Atom Industries, Lawn Edger.


2.1. Product name
ATOM LAWN EDGER – World O.E.M. Model

2.2. Description
A powerful, fast, light in weight and highly manoeuverable powered lawn edger that can edge anywhere. *
Designed as an “Original Equipment Manufacture (O.E.M.) platform” it can be manufactured and fitted with a variety of engine brands to make different models.

2.3. Principal function(s)
To neatly trim the edges of lawns with great ease, with the ability to edge anywhere including curb and gutters, around tight corners, in places of limited space in very quick time and without having to carry the unit. By simply tilting the edger sideways, it can also edge along walls and fences, eliminating the use of whipper snippers. All this cannot be achieved by any other lawn edger in the world.
The Atom lawn edger reduces the edging time of the average house from around thirty minutes using all other brands, to around five minutes using Atom.
It also functions as an “O.E.M. platform” so it can be easily supplied to other engine manufacturers, and for other companies who require supply with different engine requirements.

2.4. Brief as given by client to designer
Not applicable.

2.5. Relevance of external form and ergonomic considerations
The light in weight compact construction and "wheelbarrow" action means there is no pushing heavy machinery and there is no bending or carrying by the operator (as required with other brands e.g.brushcutters and whipper snippers). The operator walks in a normal upright fashion. This enables people such as senior citizens or people with back problems to be able to edge their lawns without any strain on their body.

2.6. Aesthetics
The Atom lawn edger has a very modern streamline design as evidenced by the super strength polyamid casing and components. This high-tech polyamid design has never been achieved by any other manufacturer in the Outdoor Power Equipment industry.

2.7. Safety
Safety was paramount in developing this edger. Many safety features that are only found on the Atom lawn edger include: *
A fully enclosed blade guard.
A ground hugging debris deflector unaffected by wheel height adjustment.
An automatic safety clutch that only engages when the throttle is activated i.e. the blade will not spin at idle speed.
A safety throttle interlock by which the throttle can only be activated when pushing down on the throttle interlock. This prevents accidental acceleration.
The operator stands behind the machine well away from the blade guard protected spinning blade. The handle cross-brace also prevents the operator pulling the machine back on himself.
A fully enclosed transmission (no V-belts etc.) means safer operator use. The Atom lawn edger meets all Australian, EU and USA safety standards.

2.8. Design problems encountered and solved
Numerous problems encountered and overcome include the design of the following: Crown Gear and Pinion
Determining what gear ratio was needed. Numerous gear ratios were tested before the 3.5:1 ratio was decided. Also different types of gears were tested before we came up with the correct spiral beval gear with heavy tooth construction to be able to stand up to constant intermittent pounding by the blade, and rough use by operators.

Clutch Drum
Size and material of drum was determined by trial and error.

Main Drive Shaft
Firstly made with flexible joint connection then different types of rigid shafts which proved expensive to manufacture. Final design of the rigid shaft was made from ground stock exactly to bearing size. Bearing locations are ridges rolled in which eliminated drilling two holes and inserting roll pins or having to use circlips and machined circlip grooves.

Blade Shaft
Originally machined from hex bar and centreless ground - very expensive. By co-operation with cold form specialist we were able to have finished part produced (to grinding tolerances) at much reduced cost.

Combined Throttle Trigger Safety Interlock and Ignition ON/OFF Switch
This involved much design work as it is the first interlock safety trigger system designed to fit tubular handles. Several designs were made and tested before finalising the design. The later EU requirement for the ON/OFF ignition switch to be close to the operator's hand involved further design, prototypes etc. before finalising the design so that the ignition switch is incorporated with the trigger throttle system.

Anti-Vibration Handle
To minimise vibration transfer to the operator, several designs were made and tested involving shape and material. This new hybrid design with polyamid handle grips and steel tubing enables us to fit the edger into a smaller carton for container shipping. Also the throttle trigger system is moulded into the handle saving assembly time. All together considerable cost savings.

Another design problem over come, was making the two piece blade cover, wheel arm, height adjuster and debris deflector all out of a single die. A total of 9 parts are made in this die, with the blade lid interlocking with the blade cover without screws, but very stable. Cross-Blade
Patents applied for. Not only is the design new but also many problems had to be over come for its manufacture. We now manufacture this hardened spring steel blade without rivetting i.e. blades now interlock each other with formed spiggots and holes in the blade.

Polyamid Main Casings
These parts have been remarked by overseas designers and manufacturers as "works of art". Extremely tough (stronger than aluminium), many design alterations and prototype mouldings had to be made to achieve the final result. The glass filled polyamid casing material is specially formulated for us to achieve high strength without distortion under work load.

Multiple use Concentric Drive Bolt
Produced in volume by cold forging. Eliminates expensive machined internally sized and threaded hubs which had to be welded onto each clutch drum. The Drive Bolt eliminates welding. It is also used on one special model edger to be supplied by us to Little Wonder, a major and prestigious USA manufacturer, as a non-rigid coupling.

2.9. Important and innovative features
Design and production costs are paramount and this new designed lawn edger has major cost reductions to aid in mass production. A total of 97 fewer parts are used over our previous models and assembly operations have been reduced considerably. *
The "O.E.M. platform” can be manufactured with a variety of engine brands to make different models. Our own Atom branded models will comprise of a 31cc 2-stroke and a 26cc 4-stroke Ryobi engine. A 1360 watt electric motor will also be added to our range of models.
The "O.E.M. platform” is to be sold to other manufacturers who can screw on their own engine and sell it under their own brand name (see “Mantis” section 2.18 para.2), or manufactured complete by us (with engine attached) for other companies (with the engine and colour of their choice) with a “badged” brand name.
The unique breakthrough patented "wheelbarrow" design enables the operator to edge anywhere. Other edgers are limited by their designs which restricts where the operator can edge. The Atom lawn edger also has the ability to instantly tilt sideways to edge up against walls and fences.
The self locking (with stress slip relief) blade shaft is unique. No key, no keyway, no spline system, as are required on other brands. Added advantage is that the blade is very easy to replace compared to other brands.
The gearbox design is the worlds first high volume “plastic” gearbox working sucessfully under such hard and stressful conditions.
The safety throttle interlock with the throttle trigger control is a first for any lawn edger. As part of this throttle control system is also the on/off ignition switch.
Cross-blade interlocking system (see 2.8 cross-blade).
Incorporated in the hybrid handles is an anti-vibration system for operator comfort.
A 6 position height adjustment allows a cutting depth of up to 80mm (3") deep.
In use each Atom Lawn Edger can easily be transported and can fit into the boot of a small car. For storage, it can be hung up on the garage wall taking up very little room.
All our edgers using this “O.E.M. platform” (with or without engine attached) will pack into a very small carton, thereby packing more units into a container and minimizing export container freight costs.

2.10. What environmental considerations if any, were taken into account?
The Atom lawn edger uses small capacity engines (under 35cc) with a fully enclosed 3.5:1 gear drive transmission for positive transfer of power to the long blades. Many other edgers have large capacity engines (with 3 & 4 HP) burning much more fuel, and use belt drives that can slip. The Atom lawn edger is very fast to use, substantially reducing the time it takes to edge, therefore there is less engine running time and dramatically less fuel consumption. Fuel consumption and exhaust emissions are up to 90% less for the same job than that required (or emitted) by other lawn edgers.

2.11. Engineering considerations (if applicable)
The engineering considerations include those listed in question 2.8 above.

2.12. Software / electronics considerations (if applicable)
Not applicable.

2.13. Product life cycle
The Atom lawn edger is maintained in the same way as any other outdoor power equipment i.e. whipper snippers, brushcutters etc. However, unlike some other brands such as three wheel type, the blade can easily and quickly be replaced in the field with two spanners. Also lubrication of gears if ever necessary is a simple task of removing a “fill and bleed” screw and squeezing grease from a bottle directly into the gearbox. If cared for the unit has a life span of twenty five years and longer for the average home owner.

2.14. Do you have a patent or design registration for the product?
Patents Granted:


678 575

Patents Pending: Japan, Europe and other countries. Design Registrations Granted:

United Kingdom
204 1668




2.15. Is the product currently being exported?
We have confirmed orders to the USA for delivery in early 2000. Customers in Europe have scheduled orders for March and April 2000.

2.16. Does the product replace goods which are currently being imported?
Absolutely! The Atom lawn edger replaces the several brands of bladed edgers currently imported as well as many whipper snipper sales as a lot of people use their whipper snipper only for edging their lawns. Apart from the engines (which cannot be sourced within Australia), the Atom lawn edger is totally Australian designed and made and our company is wholly Australian owned.

2.17. Proof of success / market potential
The world market potential is very high. This new model will be lower in cost and the same “O.E.M. platform” is to be sold internationally to other manufacturers and in different colours to use with their own engines. The same “O.E.M. platform” means much higher sales due to lower cost and with economies of scale benefits. This will be on top of our current older models of which we have sold over 20,000 units both in Australia and overseas in less than five years.

2.18. Why is it a good design and why does it deserve a design award?
There are two main reasons why the Atom edger is a good design: *
As the worlds best they are far more manoeuverable than any other edger and they edge anywhere. They are light in weight (8kgs) and can be used by anyone including senior citizens or people with back problems as there is no carrying or bending by the operator. They also complete the job much faster than any other edger and cut a much neater edge than whipper snippers. They edge faster, go anywhere, outperform any other lawn edger available in the world, and are a pleasure to use.
This new model has the added benefit of using a common “O.E.M. platform” (in different colours) and putting several brands of engines onto the edger base. We already have orders for the USA which uses a 26cc Kioritz engine and is to be marketed as “Mantis”. One European customer will use the platform for their Mitsubishi engine. Our own Atom branded model will use a 31cc 2-stroke and 26cc 4-stroke Ryobi engine. This potential of being able to adapt a multitude of engine brands means the edger can be manufactured for many different companies worldwide. This means the export potential for this designed and manufactured lawn edger is enormous.

Award-winning, world famous, Atom lawn edger

Notaras World FirstsIPAChapter_4.pdf

As young banana growers on the New South Wales North Coast, Angelo Notaras and his brother John quickly discovered the benefits of putting mechanical equipment to novel uses. For instance, they were the first to use centrifugal pumps for banana irrigation, drawing water up lifts once considered far too great except for piston pumps. They also invented a highly effective new crop spraying system. They increased production several times over, establishing practices still followed on banana farms.

However, they became so absorbed in machinery that in 1960 they left the farm and set up a workshop in Sydney. By the late 1960s their company Atom Industries had a small factory, making only their own inventions. The mainstay was a heavyduty drill that can be attached to a chainsaw.
The Atom drilling attachment is still as popular as ever, and nine-tenths of Australia’s rural fencing is built with its assistance.

The Notaras brothers realised they could invent a chainsaw far more advanced than the European models that dominated the market. Features that made it superior included a self-cleaning air filter, a carburettor that plugged into a seal, turbo-charging electronic ignition and a longer, troublefree working life. The Commonwealth Government encouraged the brothers to develop the chainsaw for commercial production. In particular, the
support would see them through the first critical years—while they found export markets to boost volume and convinced customers of the advantages of invisible features such as the air filter.

The saw went into commercial production in 1972. But a few months later, in 1973, the tariff was halved, which put an end to the domestic market for the saw. At about the same time, the Australian dollar was revalued sharply, so that export sales were no longer possible. It was a heartbreaking combination.

Atom Industries stopped production immediately and took all the specially made tooling to the scrap heap. Thirty years later European saws have finally caught up with the ill-fated Australian chainsaw. All the dearer European models are now being fitted with self-cleaning air filters and other improvements like those invented by the Notaras's, whose patents have expired.

A far more successful venture is the Atom range of motorised lawn edgers, launched in 1994. Lawn edgers then were slow and difficult to use. The Notaras brothers had the idea of making a two-handled edger that could be steered around the garden as easily as an empty wheelbarrow. In the last few years it has captured market dominance in Australia, ousting both dearer and cheaper imports.

One of Atom’s new ventures is a recently patented two-stroke engine. The conventional modern two-stroke—invented over a hundred years ago—produces a high volume of toxic fumes and wastes petrol. By using air to displace the exhaust the new engine will be cleaner and more economical.

Angelo and John work together on all their inventions. Often each will go home, after a day considering a problem, and think of a solution that night. Meeting again next morning they’ll discover that both have independently reached identical solutions. John keeps a pad at his bedside and sometimes wakes to record an inspiration.

Most of their innovations are not eye catching new machines but clever improvements to existing products. For THE CUTTING EDGE instance, in place of a conventional chuck for their drill, they invented a ring with a screw through it, which is cheaper to make but holds the drill bit tighter with use, instead of working loose like a chuck.

Atom Industries holds dozens of patents and design registrations covering a range of innovations. However, they decided not to patent their “augur stop”, which is standard on Atom drills. Whenever a knot of timber, an old bolt or some other obstruction causes the drill to jam, the augur stop switches the transmission into neutral, stopping the motion instantly. Drills are much safer with this feature, which could easily be engineered into a wide range of other powered machinery.

Because of its potential to improve the safety of millions of workers, the Notaras brothers preferred to make it freely available — just as John Ridley declined to patent his stripper (see page 8) from a desire to benefit the community.

A recent innovation is an ingeniously simple centrifugal clutch, developed for electric lawn edgers. Direct drive is standard around the world for light and medium electrical machinery. Adding a clutch radically reduces breakdowns and prolongs the life of the motor.

When they try to sell their new technology overseas, John and Angelo routinely find that major manufacturers would sooner stick with existing procedures than introduce improvements developed by little-known outsiders. As a result, most of the superior technology in their mechanical products remains unique to Australia.

Curiously, though, Australian manufacturers
rarely take the opportunities presented by Atom’s innovations. The clutch, for example, could readily be adopted in all sorts of appliances and tools to give Australian products a quality advantage. Angelo suspects that experts working for some manufacturers are reluctant to concede that they could have been doing better all along with something they didn’t think of. That may be easy to say, but it underlines a problem repeatedly faced by Australian inventors: their difficulty in getting attention and credence, without vast resources for sales promotion of their ideas.

The brothers often win awards for innovation, which can be a useful aid in promotion. A wall at Atom Industries’ modest inner Sydney factory is crowded with them. Amongst them are the Mechanical Engineers of Australia Product of the Year
award, four years running from 1994 to 1997, for various lawn edgers; and the 1976 Inventor of the Year Award for the Atom electric ignition system. Frequently inventions aimed at making better, more durable products lead to significant cost savings, and vice versa.

At the moment the two brothers are working on a plan to reduce from seventeen to eight the number of pieces in the assembly at one end of the lawn edgers. This could take dollars off the manufacturing cost. Like many simplifications in assembly techniques that they have worked out over the years, it will speed up their output.

When Australian manufacturers have to compete with those in other countries, it is not good enough for them to be equally efficient, or able to match the quality of an import at equal price. They have to do better just to be able to survive.

Astonishing though it sounds, Australia’s tariff regime operates to protect overseas manufacturers from local Australian competition. For example, if Atom Industries imports an engine for one of its lawn edgers, it has to pay duty. But a lawn edger made in America with the same engine comes in duty free. In this way Australian manufacturers are effectively forced to subsidise their overseas competitors, to the extent of hundreds of millions of dollars every year. In recent decades, many have shut down their operations; and, saddled with this handicap, many others will have to do so as time goes on.

Thanks to on-the-spot ingenuity, Atom Industries is too far ahead of the competition to be immediately threatened. But in the long run all such enterprises are vulnerable to foreign takeovers followed by transfer of their plant to other countries so that “high” Australian wages need not be paid.

Chippy’s grant awarded to Sydney team

The inaugural Peter Frilin­gos Heart Foundation Re­search Grant was awarded to Sydney doctor Brett Garner yesterday.

The Daily Telegraph, 2GB and the National Rugby League helped raise more than $70,000 for the Heart Foundation in memory of chief rugby league writer Peter “Chippy” Frillngos, who died of a heart attack at his desk in May last year.
Dr Garner and his research­ers from the University of NSW will use the grant to develop drugs that promote cholesterol removal from the arteries.
Mr Frilin­gos’ widow, Maureen, sel­ected the re­search pro­ject winner.

Daily Tele­graph editor David Penber­thy said yesterday, it was an honour to help fight heart disease in Chippys memory.
“He was a mentor to a gen­eration of sports writers, a wit with words and a friend to everyone here,” he said.
“Every year over 50,000 Aust­ralIans die after a heart attack. Chippy was one of those and he was the one we all knew, so it makes us proud that we do something in his name that will make a difference to heart disease in the future.
“If there was anything Chippy didn’t like, it was people mak­ing a fuss of him. He will be looking at us now, saying:
"Turn It up! Stop gibberlng and get on with it."

Newsletter of the Faculty of Medicine and Medical Graduates‘ Association:
April, 2004. p. 19

Mitchell Notaras, a graduate of Sydney University and a resident at the Royal Prince Hospital, has founded a scholarship in at the Royal Prince Alfred perpetuity in colo-rectal surgery.

The University has received a donation of $1.1million. Mitchell is the son of a Greek immigrant. His father came from the island of Kythera and settled in Grafton,
in NSW. The family became prominent citizens in the town. Mitchell was educated at Grafton high school and
Newington College in Sydney. Drs Mulhearn and Harris,who were doctors in the town stimulated his interest medicine. Both of them had sons who later joined the staff of RPAH.

After graduation he spent two years as
resident medical officer at the hospital. During that time he became interested in surgery and met various visiting surgeons including Rodney Maingot with whom he was associated later in London.

Mitchell travelled as a ships surgeon to England where he obtained jobs at Hammersmith, St Marks and University College Hospital. After obtaining his Fellowship he became Senior Lecturer and
Consultant Surgeon at University College Hospital.

Mitchell was appointed Consultant Surgeon at Barnet and Edgeware General Hospitals where he met and assisted Australian trainees.He was a teacher in surgery at the University of London.
He visited and lectured in many countries and was a named visiting Professor in Norway, Brazil and the Sudan.
Throughout his surgical practice his main interest was colo-rectal surgery.This was stimulated by his time at St Marks. While there he described and published the operation of lateral anal sphincterotomy which remains the procedure of choice for the treatment of anal fissure.
Despite having a busy surgical practice he established,with others, a company, bgene, which became a leader in Europe, specialising in the manufacture of molecular biological reagents, instrumentation and, through collaborations with universities and industrial partners, gene and DNA technology.After some years Abgene was taken over by the Apogent Corporation of the USA.
Dr Notaras studied medicine in Australia with the help of a Commonwealth Scholarship. He has remained grateful for the eduction he received at the Univeristy and the Hospital. He also had a desire to contribute to education, particularly in the field of colorectal cancer. As a result he has established a three-year scholarship which will be available to post fellowship scholars. The program is for one-year research at the University of Sydney, a year in an approved overseas unit of excellence and a year as a senior registrar in colo-rectal surgery at RPAH. The recipients will be selected jointly
by the University and the Colo-rectal Surgical Society. The scholars will be expected to proceed to a higher degree at the University.
To fund the scholarship, Dr Notaras has donated $1.1million. A scholar will be appointed every two years.
