SKETCHES OF THE ORIGINAL COFFEE POT. Click on the images for an enlargement.

The drawings above show the layout of the Hudson Bros (Clyde) steam tram bogie which was purchased by the Toronto Hotel and Tramway Co.in 1899. A timber cabin was built over the machinery. It was then used to pull the tram of one covered carriage and a flat top goods wagon between Toronto and Fassifern.

The boiler was a vertical fire-tube, 3 ft in diameter, 5 ft high, and coal fired, producing steam to 200 lb/sq inch.

The engine was triple expansion with four vertical cylinders, two over each crank in tandem form. The High Pressure cylinder was of 5 inch diameter and the intermediate was 6.5 inch diameter. Low Pressure steam finally entered two cylinders each 7.5 inch dia. Steam entered the HP at 200 psi and was finally exhausted from the LPs at 22psi. The crankshaft and axle was of the one unit. In later years this engine operated as a twin simple with the two top tandem cylinders removed.

The cast iron brackets on which the cylinders were mounted contained slots enabling the engine unit to slide up and down with the sprung cranked driving axle. Side cranks coupled the front and rear axles.
