The following text has been translated from advertising literature published by National Farm Machinery Co. of Montamagny, Quebec, about 1921. The literature was translated from the original French by students in the Petitcodiac Regional High School in Petitcodiac, New Brunswick, where Donald Taylor teaches.

The National engine, which won the gold medal at the last Provincial Exposition, is so superior that it's not necessary to demonstrate. It has proven this by how it is fabricated as well as by its principles and how it functions. It leaves all the other machines on the market today far behind.

General advantages of the National engine. The mechanisms of our engines are simple. Everyone with a little attention, even without experience, can succeed in making it work. Also, we make a machine that costs almost nothing and is so inexpensive to run that all those who need more power just can't pass up a National engine. Superior material. Our engines are built from the best materials, by workers with great experience and are sold by responsible agents and manufacturers. They are, in the highest degree, built solidly, efficient, resistant, and they have a simple mechanical structure.

Scientific service. Our chemists are doing every detailed analysis of all the pieces in the engine. Before it leaves the factory it undergoes a service inspection. They are not shipped out of the factory until the inspector certifies that the construction is done perfectly and that it produces a surplus of power.

Economy of the combustion. Because of the simplicity of the models and the perfect balance of the parts of our engine, the length of the piston, the size of the iron wedges, the appropriate weight of the flywheels, the precision and minute drilling of the piston rings and the force of the shaft; thanks also to our method of holding the combustion charge ready for exhaust by the valve, the attention that we give to the general construction and to several other points described later on, our motors are without contest the most economical ever built in this country. Our clients who already have a National motor know that their machines painlessly pay for themselves in no time by the economy of the combustion.

Base. Like the foundation of a. house, the base of the motor is essential for it to last. In our motor, it is separated from the cylinder, the surface is smooth to receive it, and the sub-base is bolted solidly to assure perfect alignment. This base is exceptionally large to conserve the rigidity of the iron that will not move under load.

Crankshaft. The crankshaft is steel forged with carbon with a steam hammer, and not welded. This increases the resistance force. The crankshaft of each engine is big enough to support easily the effort needed for the total development of its power, even under adverse conditions. The crankshaft leaves enough space on each side of the motor for the pulley to be mounted on either side.

Piston. Pistons are made of homogeneous metal, well polished and perfectly fitted to the cylinder. The piston is of formidable weight to assure expansion and compression are equal when heated.

Rings. The rings of the piston are made of special metal, well turned, with a slightly arched exterior, very elastic, well fitted and machined on every contour to assure efficient compression and perfect ignition, which is necessary to obtain efficient power.

Connecting Rod. All our motors have a steel connecting rod also forged by a steam hammer. It forms an 'I' shape and its stiffness supports the effort of the output. Its length is proportional to crankshaft to assure a uniform distribution of power and to eliminate unnecessary strain. The iron wedges of the connecting rod are coated in tin. They are kept in place with bolts and safety nuts.

Wheels. In our motors they are of convenient dimensions to get the greatest advantage of extra force after each explosion. They have the weight needed to support the shock of the explosion and assure a regular speed that is the purpose to the motor.

Speed regulator. The motor regulator is built very simply and works perfectly, even when the machine is at top speed. It controls effectively the function of the motor.

The muffler. The muffler, forgotten by others, has been given special attention by us. It is constructed in such a way to suppress any danger of an accident even when they're used inside a building. Carburetor. It is easy to pretend that a gas motor functions with ordinary oil, but successful usage must be based on practical experiences. Our carburetor was built to render possible effective use of petroleum (kerosene) as fuel. There are three important and essential points for a petroleum motor: vaporization, compression and spark. Our carburetor uses all these vital points to make a perfect mechanism.

Cylinder head. The cooling is by circulation of water. The cylinder head is fitted to the cylinder by a liquid tight joint that fits perfectly. It can be replaced separately in case of accident. The valves are in the head. Oiling. The cylinder has a lubricating system which adjusts to regulate the flow of oil that lubricates the piston, and the end of the connecting rod. The crankshaft end of the connecting rod is lubricated by grease as are the crankshaft bearings. The smaller parts are arranged so that they are lubricated easier and conserve oil.

Magneto. All our motors are supplied with a Webster three pole magneto that is, in fact, a small alternator inductor. In this magneto, the constructors ensured that it not only has excellent ignition but also is long lasting and durable.

Bearings. These bearings, large, substantial and coated with anti-friction metal, allows the machine to operate without vibration. The bearing seats are smooth and the oil drains assure perfect lubrication. The bearings are replaced as easily as the ones in an automobile. This is an important advantage for the life of the motor.

Ignition. The ignition is very important for the spark is essential for a good working motor.

Cylinder. The cylinder is bored with great precision and the surface smoothed with great care to ensure accuracy. The water jacket around the cylinder is complete and large enough to ensure perfect cooling. Our motors don't suffer with temperature changes and work well in cold weather without losing their effectiveness.

Finish. All our motors are finished by hand. The oil, paint and varnish that we use are the best on the market. The exterior surface is covered by two good coats of adhesive paint, then polished carefully before receiving the final coat of varnish.

With a 'National' motor, the buyer is his own expert.

14 POINTS OF THE NATIONAL MOTOR

1. The National motor is essentially Canadian.

2.  Each National motor develops more power than expected.

3.  All pieces of a National motor are interchangeable and can be furnished at any time.

4. Each National motor produces its spark by means of a Webster magneto and not by means of a battery.

5. The National motor is economical because with the minimum fuel, it produces the maximum work.

6. The National motor, thanks to its regulator, can change speeds without stopping.

7. The National motor has a long, heavy crankshaft forged by a steam hammer and not welded like many others.

8.  The muffler is built in a fashion to avoid all danger of fires so that the motor can be used indoors.

9.  The simple spark mechanism, strong and easily changed, has perfectly insulated electrodes.

10. The National motor does not produce vibrations and therefore works with more force and with less wear and tear.

11. The cylinder here has a water circulation system that prevents the heating of the valves and ensures more durability.

12.  Our carburetor is perfected; at all times and at all speeds it produces a perfect mixture.

13. We have gathered in the workshop of National Motors the best experts in the country.

14. The National motor is not shipped to our clients until it is minutely examined and approved by our inspection service.

Our motors are mounted on a hardwood truck. In each machine's box we put a can of oil, a box of grease, a can niter of cylinder oil, a wing-nut key, an instruction book containing a list of spare parts, and inspection certificate signed by the chief inspector. Before starting our motor, the client should read the instruction book.
