Specification of Letters Patent.

Patented Mar. '7, 1922.

Application filed January 10, 1921. Serial No. 436,268.

To all whom it may concern:

Be it known that I, GEORGE CHARLTON VVILDMAN, a subject of the King of Great Britain, residing at The Cedars, Riley Crescent, Penn Fields, Volverhampton, Eng land, having invented certain new and useful Improvements in Engine-Starters, of which the following is a specification This invention comprises certain improve ments in or relating to means for facilitating the starting of internal combustion engines. o

According to the present improvements the device is a self-contained unit and comprises a petrol recptaclelocated internally of a hot water receptacle, openings being lprovided for pouring in a quantity of petrol into the petrol receptacle and for pouring a quantity of hot water into the hot water receptacle when it is required to start up the engine, in combination with means for attaching the device to the induction pipe of the engine whereby petrol is drawn into the cylinder or cylinders on the suction stroke of the engine.

Figure 1 is a sectional elevation of a double tun-dish constructed according to this invention.

Figure 2 is a central longitudinal section of a device constructed according to this invention, and V Figure 3 is a transverse section on line X X of Figure 2 looking in the direction of arrow a.

According to a convenient embodiment of this invention the device comprises a cylindrical or other shaped receptacle 1 for receiving hot water, and a cylindrical or other shaped receptacle 2 enclosed therein for receiving petrol. The receptacle 1 comprises a cylindrical wall 3 and flanged end plates 4 and 5 which are soldered thereto. The receptacle 2 comprises a cylindrical tube which fits in thelsockets 6 and 7 on respectively the end plates 4 and 5. The p end plate 4 has formed thereon a projection 8 and a hole 9 therein registers with holes in the walls of the cylindrical members 2 and 3 to form a petrol inlet to the receptacle 2. A hole 10 is formed in the wall 3 to form an inlet opening for the hot water. A boss 11 having a hole 12 therein is provided on the end plate 5, such hole 12 being located at the bottom of the receptacle 2 and forming the petrol outlet from the receptacle. A tap or cock 13 is provided with screwed ends 14 and 21, one end having the upturned nozzle pipe 15 fitted thereon. The tap or cook 13 is screwed into a tapped hole into the induction pipe of the engine, the up turned end of the pipe 15 thus passing into the interior of the induction pipe and being upwardly directed. The bore of the tube 15 is sufiiciently'small to spray the petrol, the upturned end not only directing the spray upwardly but also preventing petrol running out of the receptacle 2 by force of gravity. This pipe 15 has a tapered end 22 for tightly fixing thesame into the tapered end of the bore of the ltap, thus enabling such pipe 15 to be fixed in any "desired -=po'sition in relation to the tap. The 1 tap 13 is normally retained screwed into the induction pipe of the engine and to facilitate connecting the starter thereto a union is carried by the boss 11. This union comprises a milled disc 23 rotatably mounted onthe pipe 24 which is screwed into the boss 11. The milled disc is retained on said pipe 24: by means of the collar 25 and the screwed bore is adapted to screw onthe end 21 of the tap, a washer 26 ensuring a pctrol tight joint. For the convenience of pouring in the petrol and hot water the double tun-dish 16 is provided, the pipe 17 thereon entering the hole 8, whilst the pipe 18 enters the hole 10. An air vent 20 is drilled in the member 5 to allow the petrol to readily flow into the receptacle 2. A drain cock is fitted to the wall 3 for the purpose of draining away the water after the device has been used.

When it is desired to start the engine, for instance, in cold 'weather the device is screwed on to the tap 13, which as stated is normally retained screwed in position on the induction pipe. A quantity of petrol is contained in the receptacle 2 and boiling water in the receptacle 1, which thus heats the petrol in the receptacle 2 and causes such etrol to readily vaporize. The crank shaft is then rotated either by a self starter or by the starting handle, when it will be found that the gas drawn into the cylinder will be fired after the first compression stroke. The tap 13 need only be opened to allow petrol to be drawn into the cylinders immediately before starting up, thus providing against the likelihood of the petrol being drawn away before the time required to start the engine. The carburetter throttle is preferably closed while starting up with the petrol contained in the receptacle 2 so that a charge of petrol may be drawn into the cyl nder, the throttle, however, being then opened im- 'mediately after the engine commences running, and in the case of hand starting the throttle is opened after the charge is drawn in but before the engine is started. 7

The tap 13 is, in the case of a multiple cylinder engine, fixed to the manifold at a point before it branches off to the several cylinders, If desired fastening means may be incorporated so that the device may be retained .normally'in connection with the induction, pipe.

Claims.

1. A device for facilitating the starting of internal combustion engines co'mprisinga hot WLliGPl'BCGPtEtClG, a petrol receptacle located internally of the hot water receptacle, a conduit leading from the petrol container to the induction pipe of the engine, and means for fitting the device to the induction pipe, substantially as set, forth.

- '2. device for facilitating the starting of internal combustion engines comprising a hot Water receptacle, a petrol receptacle located internally of the hot Water receptacle, a conduit leading from the petrol container, a tap or cock adapted to be fitted to said "conduit and to the induction pipe, and a nozzle pipe fitted to the side of the tapente'ring the induction pipe, substantially as set forth.

3. A device for facilitating the startingof internal combustion engines comprising a hot Water receptacle, a petrol receptacle l0- carted internally of the hot Water receptacle, a conduit leading from the petrol container, a union carried by such conduit, a tap or cock detachably screwed to said conduit and screwed into the induction pipe, and a nozzle pipe upturned at one end and tapered at the other end, which. latter end is adjustably fitted to the cock, substantially as set forth.

In Witness whereof I have signed this specification in presence of two Witnesses.
