appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure 1 is a longitudinal sectional ele rational view of my starting mechanism, secured to an engine cylinder, shown fraginentarily with the section taken through 1--1 of ig. 2, showing the means in con nection therewith for indicating the position of the isten in the engine cylinder and showing oy dotted lines certain shifted posiions of the hammer and breech block; Fig. is a longitudinal sectional view thereof, 'alzen through 2-2 of Fig. 1, showing cerrim P-r -acilitate the illustration; Fig. 3 is a side elerational view of the cartridge exploding mechanism, der, with certain parts and portions theref broke away and in.- section, and Fig. l is a transverse sectional View thereof, taken through '-li of Fig. 3.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

The barrel 1, adapter 2, engine cylinder 3, gasket 4, cartridge 5, frame 6, breech block 7, pin 8, spring 9, screw 10, hammer 11, pin 12, firing pin 13, spring 14, firing pin retaining screw 15, spring 16,

spring casing members

17 and 18, pin 19, screw 20, trigger member 21, spring 22, screw 23, valve 2i, screw 25, spring 26, washers 27, nut 28, spring 29,

spring casing members

30 and 31, screws 22 and 33, pins 34, extras tor 35, camshaft 36, valve rods 87 and the piston position indicating members 38 and 39, constitute the principal parts and portions of my engine starting mechanisnn The barrel 1 is provided at one end with a reduced threaded portion 1, which is adapted to be screwed into a threaded'recess of the adapter 2, which adapter is also provided with a reduced, externally threaded portion 2, which portion is adapted to be screwed into a threaded recess in the wall of the engine cylinder 3. It will be noted that the adapter 2 is used only when the reduced I portion of the barrel does not conform with the recess provided in the engine cylinder, and further, that the externally threaded portion of the adapter is made to accomm0- date the hole already provided in the engine cylinder. It will also be noted that the bore of the barrel, the adapter, and the hole ain parts and portions thereof in plan to separate from the engine cylini through the cylinder wall are in alignment with each other to facilitate the passage of the gases, under pressure, into the engine cylinder. Interposedbetween the end of the barrel and the adapter is a gasket 4. The bore of the barrel at its opposite or outer end is slightly enlarged to receive the cartridge 5, of special construction, which is retained in position by the breech block 7 The cartridge 5 is provided with a paraffin or similar readily combustible wad to retain the powder therein, which wad is quickly burned up when the explosion takes place. Said outer end of the barrel is also-externally threaded to receive and support the frame 6 in which is pivotally mounted the breech block 7 by means of the pin 8. Said breech block is retained in position against the end of the barrel and the cartridge by means of the sprin 9, secured within the frame 6 by means of the screw 10. A hammer 11 is also pivotally mounted in the frame 6 by means of the pin 12 extending therethrough and secured in the frame. Said breech block 7 and hammer 11 are so constructed and positioned relatively to each other that the breech block bears against the hammer member and cannot be forced backwardly when the hammer member is forward from its extreme rear position. Nor

' can the hammer be released and allowed to move forwardly when the breech block is drawn backwardly or disengaged from the rear end of the barrel 1. A firing pin 13 is reciprocally mounted ,in the breech block 7 and retained therein by the screw 15. The firing pinjs retained in a withdrawn position by the spring 14:, positioned around the same and between the shoulders within the breech block and on thefiring pin. When the hammer member 11" is released, it is 16, positioned within the telescoping

spring casing members

17 and 18, the member 18 being pivotally connected to the hammer member 11 by means of the pin 19, and the other casingv member being pivotally mounted within the frame 6 by means of the screw 20. The hammer member 11 is retained in a backward or cooked position by means of the trigger member 21, reciprocally mounted in the lower portion of the frame 6. The rear portion of the trigger member 21 is reduced and resilient, which permits the same to be forced downwardly'or away from the hammer member by means of the down wardly extending pawl portion 11 on the latter. Said trigger member is further held in engagement with the pawl portion 11 by ates or trips the hammer for firing. The

lug 21 spaced from the end of the trigger member and from the lug 21, extends a greater distance from the trigger member,

and is adapted to retain the hammer memmember, which portion extends outwardly through the frame 6, and is adapted to be depressed manually. At the opposite end of the trigger member 21 and outside of the frame 6 is provided an upwardly extended portion 21 provided with a slot 21 through which slot extends the screw 25, which piv otally connects the trigger member with the valve24. The tapered valve 24 is rotatably mounted in and extends transversely through an enlarged portion of the barrel 1, a hole 24 being provided in. the valve to provide a continuous passage from the outer end of the barrel to the engine cylinder. The small end of the tapered valve is reduced, forming a straight portion24", which extends through the wall of the barrel. Around this reduced portion is positioned the compression spring 26with washers 27 at either end thereof bearing against the barrel and the nut 2-8, which nut is secured "to the end of the portion 24 for adjusting the tension of the spring 26. The enlarged end of the valve is provided with an outwardly extending lug 24, in which is se-' barrel, which serveas stops for the open and closed positions of the valve. The valve 24 is held in a closed position, shown in Figures 1 and 2 of the drawings, by means of the compression spring 29, positioned in the telescoping

spring casing members

30 and 31,

the former being pivotally connected to the frame 6 by means of the screw 32, and the latter casing member being pivotally connected to the lug 24 by means of the screw 33. Reciprocally mounted in the outer end of the barrel 1 is the extractor 35, as shown best in Fig. 2 of the drawings and by dotted lines in Fig. 3. Said extractor is provided with a downwardly extending portion 35, which extends into the recess-7 of the breech block 7, as shown best in Figs. 1 and 3 of the drawings, the ends of the recess portion engaging the portion 35", withdrawing or 1 forcing the extractor inwardly, for extracttion engine, which operates the valve rods.

37 when the cam-shaft is positioned at the side of the engine frame, is also used to indicate the position of the piston within the engine cylinder prior to starting the engine with my starting mechanism. This starting position of the piston is a position slightly past the top dead center with a charge of combustible gases in the combustion chamher. On the cam-shaft 36 is secured an indicating linger 38, which extends outwardly therefrom, and spaced therefromand in line therewith when the piston is positioned as stated, is positioned a corresponding indicating finger fixedly secured to the frame of the engine. it is obvious that since the speed of the camshaft is one-half the speed of the crank-shaft, as in an engine of the fourcycle type, the indicating fingers 38 and 39 will align with each other once every two strokes of the piston, and when properly secured to the cam-shaft will indicate the proper position o the piston for starting.

It is obvious from the above that when the indicating fingers 38 and 39 are positioned in. alignment with each other, and with a cartridge 52 in the chamber of the barrel, the opening 24 of the valve 24 will align with the bore of the barrel when the handle portion of the valve is turned clockwise, drawing the trigger memberfil outwardly from the frame 6, rotating the hammer member 11 about its pivot, and by the time the opening 2 of the valve is in alignment with the bore of the barrel 1, the harm mer member will be released by the trigger member, permitting the same to spring forwardly to engage the tiring pin and discharge the cartridge, permitting the gases to be forced into the combustion chamber of the engine cylinder, forcing outwardly the piston and igniting the gases therein, Immediately, when the handle 24 is released, the spring 29 will automatically close the valve and force the trigger member 21 into the frame 6, permitting the same to engage the pawl portion 11 of the hammer member 11. Though I have shown and described a particular construction, combination and arrangement of parts and portions, 1 do not wish to be limited to this particular construction, combination and arrangement,

but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It 1s obvious from this construction that there is provided an internal combustion engine starting mechanism which may be readily connected and secured to an internal combustion engine cylinder for forcing outwardly the piston in the same and simultaneously igniting the gases therein, thus starting the engine; that there is provided a novel manually operated and automatically controlled mechanism of this class, and a mechanism in which a cartridge is used to supply the energy for moving the piston in the cylinder to which it is connected and is adapted to ignite the gas therein; that there is provided aunechanism of this class in which the trigger mechanism for discharging the cartridge is operated simultaneously with the opening of the valve by which the cartridge chamber is connected with the engine cylinder; that there is provided a mechanism of this class in which the valve and trigger are automatically returned to their original position when the operating lever is released; that there is provided an adapter for a mechanism of this class by means of which the mechanism may be readily secured to any gas engine cylinder at the spark plug opening or other similar opening therein; that there is provided a novelly constructed mechanism of this class, and a mechanism which is very simple and economical'o-f construction, du-
