and useful Improvements in Gas-Engines, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in gasen'gines and my invention consists in features of novelty hereinafter described and pointed out in the claims.

Figure I represents a side elevation of my improved gas engine. Fig.'II represents a vertical section of a portion of my device, showing the valve rods and means for operating the same. Fig. III represents an enlarged detail viewof my improvement for adjusting the length of the ignition rod. Fig. IV is an enlarged detail perspective view of the lever and pawl for operating the gas supply valve. Fig. V is an enlarged detail section of a device for operating the gas supplyvalve. Fig. VI is an enlarged detail view of the valve operating device and showing my improved governor in connection therewith. Fig. VII represents an enlarged detail vertical section of the valve operating device. Fig. VIII is an enlarged vertical section of the carburetor. Fig. IX is a transverse section taken on line IX, IX, Fig. VIII.

Referring to the drawings: 1 represents the base of my engine, and 2 the frame to which the various portions of the device are connected.

3 represents the main drive-shaft, and 4 the balance wheel mounted on the same. On one end of the drive-shaft is located a double.

staggered pinion 5, with its teeth extending at a different angle from that of the driveshaft. The pinion 5, meshes into a gearwheel 6, having its teeth, of course, constructed on the same principle as the teeth of the pinion 5; said gear-wheel also being double, similar to the pinion. The gear 6, is journaled at 7, to the frame 2. (See Figs. II, and VII.)

8 represents a roller journaled at 9, on the outer face of the gear-wheel 6, saidroller 1'e-* volving with said gear-wheel, and permitted to revolve on its pinion 9. As the fiy-wheel 4, travels in the direction shown by the arrow in Fig. I, the pinion 5, will be driven in the same direction, or in the direction shown by the arrow in Fig. VI'which will cause the .to the gas admission valve and permits the gas to enterinto the cylinder. The lever 10 is provided with a beveled shoulder 13, against which the roller8 bears and gradually'presses down said lever.

14 represents a pawl which is pivoted to the lever 10 by a head 15, (see Fig. IV) which passes into an opening 16 in said lever (see Fig. V), the pawl havinga lower beveled end 17, and an arm 18, which fits into a slot 19, in the lever 10, said arm having at its outer end a weight 20, for holding the pawl when in its normal position, into engagement with the gas operating valve rod. The lower beveled end of the pawl 14, engages, when in its normal position, a shoulder 21 on a thimble 22, which is attached to the upper end of the rod 23 to which the gas valve is secured.

24 represents an additional shoulder on said thimble with which the pawl 14, at times engages.

25 represents a pendulum, which may be pivoted at 26, to the frame 2, said pendulum having an adjustable beveled sliding block 27,1ocated thereon, and also having an adjustable weight 28 located thereon. The lower end of'the pendulum 25 is pivotedto one end of a rod 29, the other end of said rod being pivoted at 30 to-a quadrant shaped wiper 31, said wiper being pivoted at 32 to the frame. As the roller .8 travels around with the gear 6 in order to depress the gas admitting valve rod, said roller will come in contact with the beveled block27 on the pendulurn 25,- and throw the same outward to a certain degree, which is regulated by the momentumv of said roller. As the pendulum 25 is thrown outward, the wiper 31 is drawn into engagement with the pin 33 on the pawl 14; and if the momentum is sufficiently strong the wiper 31 will be drawn against the pin 33 with sufficient force to throw the pawl out of engagement with the upper shoulder 21, on the thimble 22 thus not admitting so great a charge of gas into the cylinder, and the pawl will be allowed to press against the lower projection 24 on the thimble 22, thus opening the gas supply valve to a lesser degree, and admitting a smaller charge of gas. Should the velocity of the engine be sufficient to not require a new charge of gas on every revolu-' tion of the roller 8, the pendulum 25 will be struck with sufficient force to draw the wiper 31, down sufficiently far so that an enlargement thereon, will come into engagement with the pin 33 and throw the pawl entirely out of engagement with the thimble 22, thus not opening the gas valve and not admitting any more gas until the velocity has been sufficiently decreased and a further charge of gas is demanded for the operation of the engine. As the roller 8 performs its circuit it comes in contact with a beveled head 36 located on the upper end of a rod 37 to which the valve which controls the ignition tube is secured.

38 represents a rod to the lower end of which is secured a valve 39, which controls the exhaust port of the engine, said rod and valve being operated by a roller 40 on the inner face of the gear-wheel 6, said roller operating a lever constructed similar to the lever 10 which operates the gas valve.

41, 42 represent lugs on the gear 6, one on each gear, through which passes a pin 43, on which pin are located coil springs 44, 45; the object of said springs being to prevent backlashing in said gears.

46 represents acasing surrounding the gear, having a removable face 47 which may be removed in order to inspect the gear. This casing may be partially filled with oil, so that as the gears are operated the oil will be thrown up and over said gears and the other operating devices, and the latter thus be thoroughly lubricated at all times.

Where the ignition rod, gas supply valve rod, and exhaust valve rod pass into the lower portion of the casing, I have shown tubes 48, extending upward in said casing for the purpose of preventing the oil from passing out around said rods, the thimble 22 upon the-rod 23 telescoping with the tube in which said rod operates serving also for this purpose.

49 represents a set screw for limiting the backward movement of the wiper 31.

50 represents a set screw for limiting the forward movement of the pendulum 25; and 51 represents a set screw for limiting the downward movement of the weighted end of the lever 10. The rod 37, to which the valve 52 which controls the ignition tube is secured is made in two parts, said parts being secured to collars 53, 54, between which is a movable collar 55, having a handle 56, and a projection 57, on the lower side of the collar with a V-shaped space 58, in the collar 54, into which said projection may pass when it is desired to shorten the rod 37, thus not opening the valve 52, and allowing the gas to be fired as quickly as it would be otherwise, which is necessary at times when starting the engine. When it is desired to lengthen said rod in order to fire the charge of gas more quickly, the collar 55, is turned by the handle 56, the projection 57, being forced out of the V-shaped opening 58, up onto the lower collar 54, thus lengthening the rod, as shown in Fig. III.

59, 60, represent smooth faced disks, located on the pinion 5, and gear 6, which bear against each other and thus relieve the strain to some extent on said gears and their journals, as they are sometimes subject to greater strainthan at other times while the engine is in operation, said disks also lessening the noise of the gear.

61 represents the gas supply valve, located on the lower end of the rod 23, said rod having an arm 62 adjustably secured thereon which may be set so as to come in contact with the collar 53, on the ignition rod 37, so that as a supply of gas is being taken into the cylinder, said arm will depress said rod 37, thus opening the valve controlling the ignition tube and allow any burned products of cornbustion contained therein to pass out.

63 represents the ignition tube; 89, the port through which the gas enters, which then passes to the valve 61 into the chamber 65, and from thence through a port 66, into the cylinder, where it is fired.

90 represents the port through which the exhaust is discharged past the exhaust valve 39, when the same has been opened by its operating device.

68 represents flat springs on the ignition rod 37, 69 flat springs on the gas supply rod 23, and 70 flat springs on the exhaust valve rod 38, said springs being fixed at their lower ends and having their upper ends secured to adjustable collars 54, 72, and 71, by which the springs may be adjusted, in order to hold the respective valves situated on the lower end of said rods in a closed position while in their normal condition.

73 represents the frame of the carbureto which is attached to the walls of the chamber 65, said carburetor having a removable bottom 74, and a removable top 75,by which access may be had thereto.

76 represents a tube through which the gasoline or coal-oil is admitted.

77 represents a chamber in which the tube is located, said tube discharginginto an opening 78, controlled by a valve 79, the stern of said valve having an opening 80 at its upper end into which the set-screw 81 extends, said set-screw forming a guide and limiting the upward movement of said valve. The valve 79, is held closed by a coil spring 82 surrounding the stem of said valve and pressing against the disk 83 thereon.

The gasoline or oil enters into the carburetor from the tube 76, through the opening 78, into a chamber 84 where it is carbureted bymixing with the air which passes in through an opening 85, in the wallof the carburetor and through the holes 86 in the same, the gas then passing through openings in a disk 87, located on the lower end of the valve 79, said gas then being deflected by the funnel shaped portion 88 and then passing through openings in the disk 83, thence through a port 89 and then into'the cylinder through the gas valve 61, where it is fired. Said valve 79 is lifted by thepressure of the air coming in through the openings and the holes 86 in the wall of the carburetor, in its effort to enter and fill the vacuum formed in the main cylinder at the beginning of the out stroke of the piston,

and remains open until the out stroke is nearly completed or until the gas valve 61 is closed. The products of combustion pass out from the cylinder at the proper time, past an exhaust valve 39, through a port 90 into a tube 91, located in the carburetor, said exhaust passing around the supply tube 76, and heating the same in its outward passage, thence up through a space 92, in the wallof the carburetor, and thence out through a port 93 mm conveyed to any desired point. I

94 represents a port leading directinto the body of the carburetor, through which air may be admitted at times when the gas contained therein is too dense and requires more air to be thoroughly carbureted.

I have described my device in connection with the vertical engine, but by making certain mechanical changes the same may be used with a horizontal engine.
