When running to a fire some shavings, chips, or cotton on which some paraffine has been melted is put in this smoke-pipe and lit, and as the engine is drawn along the sparks and smoke will shoot out from the top of the pipe in a very realistic manner. The seat is made of a box on top of which a back and side-arms are arranged as shown in Fig. 1, and when it is complete it is attached to the side-rails and truss. The upper edges of the side-rails are decked over in front of the box so as to make a platform, and at the front end of the frame a dash-board is arranged and held in position with battens.
A small, water-tight keg is fastened to the platform between the knees of the truss by means of screws passed up through the bottom of the platform and into the under side of the keg. One or two openings are made in the keg and a hose-coupling driven into them so that the long hose may be attached when at a fire. Short lengths of hose and couplings extend from the top of the pumps to the keg, so that when the pumps are in action the water is forced into the keg and out through the openings. There will always be a cushion of air above the water which is more or less elastic, and when the water is forced in faster than it can escape through the nozzles the air-cushion will take care of the pressure automatically.
Small carriage wheels and axles support the frame, and at the front a fifth wheel is arranged so that the front wheels can be turned. Back of the barrel the frame is decked at the under side so as to make a fuel-box where more smoke and spark making materials can be stored. It would be well to fasten a lid to this compartment so that sparks dropping from the smoke-pipe will not fall on and ignite the contents. If it is possible to obtain a force-pump it can be mounted on one of the bases arranged at the side of the barrel.
The suction-hose should come from the under side of the barrel and be attached to the base of the pump. The coupling to which the long hose is attached should be arranged at the side of the keg or it can be screwed directly on the outlet of the pump. A short length of the hose—a coupling and nozzle—may be supported on hooks and a standing Y as shown in Fig. 1. The hook on the barrel is made from a piece of iron bent as shown at Fig. 3 A, with holes bored to receive screws. If the iron is too hard to work a wooden bracket can be made, as shown at B, and screwed fast to the barrel.
