Abstract: 5181. Bruce, A. March 7. Carburetting.- Relates to carburetting-plant of the kind described in Specification No. 3243, A.D. 1907, and consists in the provision of a water motor controlled from the gas-holder, the construction of the driving - gear of the air-pumps, the construction of the petrolmeasuring device, and the provision of a purifier on the air-supply pipe. Water is supplied through a valve 125 and pipe 13 to a water motor 4, the valve 125 being controlled by the gas-holder 2, through a lever 123. The valve casing 7 of the water motor 4 is provided with a water-inlet pipe 13 and exhaust pipe 14, and is made with an extension 15 within which works a plug cock 16. The cock 16 is formed with two passages 17, 18, and has a spindle 19 which is operated by the movement of the piston 8 by means of a link 37 on a sliding bar 38 moving with the piston and engaging the end of an arm 36 on the spindle 19. In one position of the cock 16, water passes through the inlet pipe 13, passage 22, and a slot 24 and moves the valve towards the other end of its casing, live water thereby passing through the valve and passage 12 to the cylinder 4, exhaust from the other end of the cylinder being meanwhile effected through a passage 11 and the valve to the pipe 14. When the cock 16 is turned, the.actions are repeated in the reverse direction. Water may be supplied to the motor 4 from mains or from an accumulator. Fig. 18, comprising a cylindrical vessel 131 supporting a weight carrier 133 and adapted to be raised by handgear 145. Water is supplied from a chamber 136 through a pipe 137, and is led off to the engine through a pipe 138. The exhaust from the engine is preferably returned to the chamber 136. Toe piston-rod 9 of the motor 4 is connected to racks 52, 53 between which is mounted a toothed sector 51, the formation of the teeth 51<a>, 51<b>, 52<a>, 52<b> being such that, while the racks reciprocate, the sector 51 is rotated continuously in one direction and causes the reciprocation of the air-pumps 92. The petrol-supply device, Fig. 6, is driven from a rod 65 and wheel 47 geared to a wheel 46 on the axle 45 of the sector 51. The petrol tank is provided with a projecting cylinder 69 in which are reciprocated three pistons 70, 71, 72. The centre piston 71 is fixed to the piston-rod 66, while the pistons 70, 72 are simultaneously adjustable by means of right and left handed screw-threads on the piston-rod. When the pistons are at the end of their upward stroke, as shown, the space 69<1> fills with petrol through a port 73, and on the inward stroke, this petrol is discharged through a port 74, passage 75, and tube 76 to the top of the carburettor 84. At the same time, the space 69' becomes filled, and on the outward stroke, the petrol therein is discharged through the tube 76. Air is admitted to the space 69<1>, during its discharge, through a pipe 77 and ports 79, 74, and to the space 69<2> through a pipe 80, the pipes 77, 80 leading to the space at the top of the petrol tank 67. The bottom of the carburettor 84, Fig. 1, is preferably connected by a pipe 99 to the top of the tank 67. Air is drawn into the carburettor through a purifier of known construction.
