STARTER FOR INTERNAL-COMBUSTION ENGINES.

To all whom at may concern.-

' Be it known that we, LUTHER V. MoUL- TON and PALMER A. Jones, citizens of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Starters for Internal-Combustion Engines; and we do hereby declare the following to be a full,

' clear, and exact description of the invention,

such as will enable others skilled in-the art towhich it appertains to make and use the same. q

Our invention relates to improvements in starters for internal combustion engines; andits object is to provide a simple and reliable manually operated device for admitting a fluid under pressure to the engine cylinders; to provide means for automatically-controlling the adjustment and movement of said device toproperly conform the same to the engine; and to provide the devlce with various" new and useful features described andpar- Our device consists'essentially of a'manually {operated valve adapted to successively admit fluid under pressure to the respective 1 .cylinders of the engine in the order of the 30 working strokes of their pistons, and means operated by the engine to control the manual adjustment and movement of the valve and the opening and closing of the throttle, as

swillmore fully appear by reference to the accompanying drawings, in which:

Figure 1"1s aslde elevation of a devlcc' embodying our invention; Fig. 2 an end elevation of "the same with portions omitted;

valves-8 are provided in said pipes to prevent back pressure when the engine is work- 111g. y

9 is a rotative and longitudinally movable shaft manually operated by means of a crank 10.

11 represents a constantly rotated adjusting and controlling member mounted concentric with the axis of the shaft 9 and preferably journaled on the tubular portion of the valve case 3. This controller is driven synchronously with the cam shaft '17 of the engine by any suitable means so as to make one revolution to each complete cycle of the engine; the means shown being a sprocket wheel 16 on the cam shaft connected by a chain 15 to a sprocket wheel forming the member 11.

13 is a manually operated valve adjustiug and controlling member adapted tocoact with the controller 11 to adjust, the valve, to control the rotation thereof and to control the opening of'the throttle, for which purpose the controller 11 is provided with a segmental recess or openim 19, and a lug 14 is provided on the member 13 to engage therewith. -This opening 19 is elongated to permit of a limited movement of the lug therein and one end of the opening as at 27, presents a square shoulder or stop to the lug lfil: andthe other end is inclined as at 28, whereby" the lug 14 engages the shouldered end 27 to limit the manual rotation of the valve, and is forced out of the opening when brought in contact with the inclined end 28, thus longitudinally moving the shaft and permitting the throttle to close. The lug also traverses theface of the controller 11 to prevent 'opening'the throttle except when the valve 21 is properly adjusted to start the engine, as here-. after described. The valve 21 is preferably conical and has a single opening 22 through which the fluid escapes through the ports and pipes to the cylinders. Longitudinally movable in the axis of this valve is the shaft 9.- The adjusting member 13 is fixed on this shaft and is slidably connected with the valve by means of one or more pins 12 longitudinal movement of sald shaft, WhlCll' val-ve21-is at the right Each port communicates with a respective cylinder of the engine by means of the pipes 4,5, 6 and 7 as heretofore described. Thus as the valve is rotated,the openlng 22 comes successively opposite the various openings 26 in the order in which the pistons in the various cylinders of the engine perform the working stroke, and is properly controlled in its rotary movement, byv contact of the lug 14 with the end 27 of the slot 19. j

The valve case is closed by a hollow head in communication with the tank 2, by means of a pipe 25, and in this head is a throttle valve 23 to admit the fluid to the valve 21 inline with the shaft 9 and opened by the latter has a reduced end engaging and carryingdthe throttle valve as at 9. This valve 23 isclosedby a spring 24, and the shaft 9 by, the same-means is moved longitudinally controlling members.

18 is a pipe through which the tank2 may be charged with compressed fluid 1n any convenient manner. A washer 20 attached to the end of the valve: 21 serves to hold the same in place and to .hold the controller 11 on. its bearing.

The device-operates as follows: The tank 2 is-charged with compressed air or other suitable fluid under pressure by anyconvenient means and the device so adjusted that when the lug 14 is opposite the opening 19, the opening 22.will be opposite the par- .ticular port 26 which communicates with the-cylinder inewhich the piston is .on the working stroke, it being understood that the device shown is organized to cooperate with what is known as a four cylinder four cycle engine. The controller 11 being rotative once to each complete'cycle of the engine, this opening 19 will always be so positioned that it will accurately determine the proper adjustment of the valve whenever the lug 14 is brought into the opening 19 and in contact with the end 27 thereof. It will also be noted that the lug 14 traverses the surface of the controller 11 and effectually prevents opening the valve 23' except when the adjustment to properlygadmit fluid to the proper cylinder-of the-engine, also that the'movement of the engineas it starts, turns the member 11 at the'proper speed so thattas long as the lug 4 is manually held against "the end 27 of the slot, the valve 21 will be properly operated to adm1t flu d to the cylinders of the engine 'in succession as each piston therein makes the working stroke. The

other three strokes overtake the lug, 14 and move the shaft longitudinally thus automatically closing the throttle 23. If by any chance the engme should stop with the working stroke of a cylinder so nearly complete that admission '1 of the fluid thereto would not carry" theengine over the center, and start the same, or the engine stop in such position that the opening 22 comes between two ofthe: ports 26 whenthe lug 14 is in'contact with'the, end 27 of the slot,then,a backward-turn of the crank 10 would move the lug 14 backward in the slot 19 andthus open up the next preceding portin the valve case and, thus kick the engine backward byad mission of fluid to the; next preceding cylinder, whereupon a forward-movement of the valve would properly start the engine. Usually the lug would'first be opposite the face of the controller 11, and thus when turned to find the slot, it "would enter the same at the end next the incline. This would automatically find the proper adjustment to make the engine kick back if the working piston should be too low to start properly. It thus becomes only neces sary in starting the engine, to manually turn the crank 10 and at the same time press on the same to move the shaftlongitudinally." The matically discontinued and the throttle closed, whenever the engine turns so that" the controller 11' overtakes the member 13.
