ODILON BRISBOIS, CHICAGO, ILLINOIS, ASSIGNOB TO AUTOMATIC STARTER COM- I'ANY, OF CHICAGO, ILLINOIS ,.A CORPORATION OF ILLINOIS.

To all whom it may concern: 3e it known that I,'ODILON. Bnisnols, a cltizen of the United States of America, and

a resident'of Chicago, county of Cook, State of IlllIlOlS, haveinvented certain new and which is particularly adaptedto be operated manually for starting multi-cylinder hydrocarbon engines of high-powered automobiles wherein the pistons and their connections are too heavy to be readily cranked in the usual manner; and to provide a starter of this class in which the carbureted air is used for the starting charge, and-in which all of the cylinders are simultaneously charged so through the act of operating the ignition apparatus thereof. These objects. are accomplished by the device .shown in the accompanyingdrawings, in which- Figure l is a top plan of a six-cylinder hydrocarbon engine provided with starting .mechanism constructed according to this in-' vention and showing the same in position within the frame of an automobile which is shown artly'broken away. Fig. 2 is a topplan of the pump which forms part'of the starting mechanism andthe auxiliary carbureter. Fig. 3 is anend elevation-of the same. Fig. 4 is a side elevation, showing the upper ends of the engine cylinders and their connections with the fuel feed pipes of the starter. Fig. 5 is an enlarge detail showing the arrangement of the fuel inlet valve and riming pet-cock of one of the engine cylin ers. Fig. 6 is an end elevation of the s ame.,. Fi 7 1s a detail of the device whereby the charge in any cylinder-may be ignited, regardless of the position of the I brush and distributer of the spark ng circuits. Fig. 8 is a sectional detail of the same on the line AA of Fig. 7. Fig. 9 is a detail of the same on the line B-.-B of Flg.

tus which is simple in construction and;

as to insure positive starting-of the engine,

In the drawings, the engine cylinders are TAR'IER FOR HYDROCARBON-ENGILIES.

designated 2. 3 is the usual transom which Patented May 31, 1910.

' designated 1, and the frame of the vehlcle 1s separates the motor space from the remainder of the vehicle. tanks and operating mechanism of the engine do not form a part of the herein described invention, they are omitted from the drawings. The parts herein described as fuel inlets are the auxiliary fuel inlets which form a part of the starting mechanism, and they may be entirely independent ofthe fuel inlets through which the engine cylinders are charged during the -normal operation v thereof. 1

In the construction shown in the drawings, there is an individual auxiliary fuel inlet pipe 4: for each cylinder, and each of these pipes 4 is connected with its individual cylinder 1 by means of a fitting'5 which is inserted between the engine cylinder and the usual priming pet-cock 6. Each pipe 4 is provided with a controlling valve 7, and for convenience of operation, the operating levers 8 of said controlling valves are connected together and controlled by the operating rod 9- which extends through the transom 3 and is provided with a handle 10. Interposed between the controlling valve 7 and the' fuel inlet pipe 4 of each cylinder is a check valve 7. The priming pet-cocks: 6

also have their levers connected together by with an a link 11 which in. turn is connecte As the carbureter, fuel operating rod 12 extending through the.

transom 3 and provided with a handle 13.

'In the form shown in the drawings, the

starting carbureter is separate from and auxiliary to the main ca'rbureter, the former being shown at 14 in the drawings, and the.

latterjbeing omitted. 'Each-of'thef'pipes 4 -connects with the pump valve fitting 1.5

which is connected by a passage 16 with its individual pumping cylinder 17, and which is also connected by the pipe 18 with a mixing chamber 19 of the carbureter. .'Valves 20 and 21 in the'valve casing 15 control theflow of gas to and from the pump cylinders 17. In the form shown, the pump has as many cylinders as there are enginecylinders,

'and each pumping cylinder controls the sta'rtin link with means located in convenient position for manipulation by the operator of the vehicle while he is seated at the steering wheel.

The ignition of the starting charge is accomplishedbyfmeans of the same ignition apparatus which is used in the normal oper; upon of the engine, but the sparking circuit 0 which is connected in a shunt so as to be capable of short circuiting the distributor shown are assumed to be of the usual form I in which the primariesare grounded. It is then only necessary to ground the switch members 29 as indicated to complete the shunt circuit around the distributor contacts. Springs 28 normally urge the members 29 away from the contacts 27 so that in the shunts are normally open.

The, operation of the device shown is as follows :--Assume that the engine is at rest. 1

The starter fuel-fe'ed valves T are opened by pulling the handle 10. Ihen,when the pump 17 is operated, oil drawn into thecarbureter, vaporized and mixed with air.

Each individual pumping cylinder draws a quantity of the gaseous mixture from the mixing chamber of the carbureter and forces it into its respective engine cylinder l. Thus, every one of the engine cylinders is simultaneously charged with fresh gas under pressure. After a few strokes f the pump 17, the valves 7 are closed by means ,of' the handle 10, and then the sparking circuit is closed by means of the usual 'con-.

trolling switch, not shown in the drmvings. Frequently'the enginewill start on the clos- "ach'cylinder is provided with a switch located below -the floor of the vehicle, the f lever 24 is connected by operating mechanism indicated by the mg of said switch. If the engine, however,

happens to have come to rest in such position that all of the sparking circuits are open at the distributer, then by rocking the distribute! by means of the usual sparkadvancing lever (not shown), it may be possible to close one'ot' the circuits and start the engine. :If the engine fails to start after closing the switch and shifting the distributer, the operator presses the buttons 29, one at a time, thus closing the respective primary circuits and igniting the charges in the compression spaces of the respective'cylind'ers. There is therefore no position'of the main shaft from which the engine cannot he started. Even in two and four-cylinder engines, Where the cranks are so arranged that there is a position of dead center, the jar'due to the successive explosions in the cylinders hasbeen-found to rock the shaft-away from dead center and start the engine without requiring the shaft to be manually turned awaytrom dead center. v

What '[claim as my invention and desire to secure by Letters Patent is l. The combination of a inulticylinder" a battery;

hydrocarbon engine, a carburetor, of pu1nps,-one tor each cylinder, having the plunger rods connected to a single transverse bar )HSSEITOS connectin' each um Wlth the 7 b carbureter and with 1ts jrespective engine cylinder, and mechanism for causing, the oscillation of'said bar for forcing an'explosive mixture into the engine cylinders.

2. In anautomobile the colnbinationofa multicylinder hydrocarbon en ine, a carburetcr, a battery of pu1nps, one or each cylina der, having-the plungerrods connected to a single transverse bar, passages connecting each pump with the carbureter and with its respective engine cylinder, nd mechanism controlled from the seat of t e 'operator, for causing the oscillation of'said bar for forcing an explosive mixture into the engine cylinders.

3. The combination of a multicylinaer hydrocarbon engine, a carburetena battery of pumps, one for each cylinder, having the plunger rods connected to a single transverse bar, passages connecting each pump with the carbureter and with its respective engine cylinder, and a single mechanism for causing the oscillation of said bar for forcing an explosive mixture into all of cylinders.
