I saw Charles Wendel, 'The Reflector,' at the Tatton 1000 engine rally here in the UK recently, and I promised him a shot of my latest project.
The Termatt and Monahan Company is believed to have come into being in about 1910, with a series of engines starting with 1, 2, 4, and 6 HP sizes. By 1914, 9 and 12 HP sizes were added to the range on trucks.
Here in England these little 1 HP size engines are rare, with their distinctive arched base or crankcase, although I know of at least five examples. I bought my engine from a dear friend here in Kent who had it in his garden shed for nearly 40 years. I found that the governor weight and arm were missing as was the exhaust box. I was most fortunate in obtaining the parts required from the famous Alyn Foundry in the northeast of England. Mr. Graham R. Corry, the proprietor, also does various other castings for most of the popular British and American makes, as well as casting sets for scale Gardner engines; a vertical open crank, plus a horizontal engine called the RLE; plus a very easily constructed Robinson hot air engine also in scale.
My T&M, when found, had a high tension magneto fitted, an EIC magneto, a very well known magneto company which generally supplied them to the early motorcycle trade. It was originally fitted to the top right hand side of the hopper on a bracket, and chain driven from the crank. As this style of fitting was unsightly, I refitted the magneto on its original mounting plate under the arched base. And again, used the chain drive. When new, the range of T&M engines were generally fitted with battery and coil ignition, but some engines could be supplied with magneto as an extra fitting.
I'm told that if the rocker arm bracket, which operates the exhaust valve, is fitted to the head with two fixing bolts and has a small flange on either side, to hold it in the correct place, it is an earlier style engine. The later ones had one fixing bolt and a steel pin to do the same job, i.e. to steady the bracket.
Perhaps a few dimensions might be in order here. The 1 HP T&M has a 215/16 inch bore with a 3 inch stroke and a 1 inch crank throw. The flywheels are 15 inches in diameter with a two inch face.
Through the pages of GEM, I have been in correspondence with a chap in Canada who owns a complete 2 HP T&M. His engine is much larger than mine as one would expect. It has 25 inch flywheels and a 2 inch face. This engine also has the motif T&M with a circle around it cast into both sides of the hopper, whereas my engine does not have this particular feature and there is no engine plate or serial number.
The T&M marque would also appear to have many parts which are common to the Gray Engine Company of Detroit, Michigan. Amongst some of the parts are the governor and the carby, but it is not thought that either firm was connected in any way. Further information of the Termatt and Monahan Company can be found in Mr. Wendel's yellow book, page 509.
