In a gas engine, the combination with a cylinder having an igniting chamber, and an adjustable flexible electrode mounted in said chamber, and adapted to be adjusted inward and outward according to the wear, of a rotatable electrode operating with said stationary electrode and acting safely in one direction only, a hook-crank for the rotatable electrode, the shaft of the latter extending outside of the chamber of said crank, a reciprocating rod, one end having a pin normally engaged with said hook-crank when said end is rotated in one direction, and disengaging automatically when reversely rotated, an eye post forming a guide for the middle portion of said rod to guide it in its reciprocation, and means to rotate the other end of said rod and effect its reciprocation and the rotation of said electrodes.

2. In a gas engine, the combination with an igniting chamber having a screw threaded opening and of contracted size at one end, of the electrode mounted in said opening, a sleeve thereon having a flange at its inner end, insulating material about said sleeve and flange and a collar about said insulating material, and screw threaded into said opening at its larger end, whereby the said collar will press upon the hanged sleeve and interposed insulating material and maintain the said electrode in position.

3. The combination with a gas engine, cylinder having an igniting chamber, electrodes mounted therein and an operative connection therefor, of a centrifugal governor mounted on said shaft, a carburetor, and a pipe connecting its igniting chamber, a mixing and regulating valve mounted in said pipe, the valve consisting of a perforated collar to admit air and a sliding piece forming the valve proper and having a reduced central portion to admit of the passage of the charge, a lever arm to reciprocate said valve proper and actuated by said governor, and an adjustable connection between the said valve proper and the said lever arm.

527,635 Oct. 16, 1894 Gas Engine Henry Voll Springfield, Clark County, OH Abstract:
This invention relates to certain new and useful improvements in gas engines, and the particular feature of such engines that constitutes the subject of this invention is the device for regulating the quantity of the explosive agent or ingredient, which is to be mixed with atmospheric air to form the charge. This regulating device performs also, incidentally, the function of forcing the explosive ingredient into the air which forms the remainder of the charge, and in this sense this device is in the nature of a pump, one stroke of its piston acting to assist in raising the inlet valve and the other stroke operating to eject or force out the gasoline or gas taken in during the out-stroke. Combined with this piston is a hit-and-miss device consisting of a rod which strikes a blow to operate the said piston in one direction, and of a pivoted piece operated by a governor so as to move in and out of line with the striking bar, according to the speed of the engine, whereby when the speed is excessive the piston will not be actuated during one or more cycles of operation, whereby the explosive ingredient will not be taken in during the time of such excessive speed.

Claims:
1. In a gas engine, the combination with a cylinder and two valves, a supply pipe communicating with the cylinder through one of said valves and a discharge pipe communicating with the cylinder through the other of said valves, an air pipe into which the discharge pipe enters and a casing and valve permitting and cutting off communication between the air pipe and the main cylinder, a piston in the first named cylinder and a spring to force it outward, of a slotted piece pivoted to the piston, a governor whose shaft connects with said piece through said slot, and a reciprocating rod having a striking plate and actuated from the engine shaft.
2. In a gas engine, the combination with a cylinder having two valves, a supply pipe communicating with the cylinder through one of them, a discharge pipe communicating through the cylinder with the other, a piston working in the cylinder, a spring actuated rod connected with the piston, a piece pivoted to the piston and having a slot, a governor having a reciprocating shaft connected to the pivoted piece through said slot and a reciprocating rod adapted to strike the pivoted piece or not according to its position.
692,082 Jan. 28, 1902 Governor for Gas Engines Andrew Sonander Springfield, Clark County, OH Abstract:
The object of my invention is to provide a governor simple in construction, consisting of few parts that can be easily replaced, the combination and adjustment being such as to give perfect regulation.

Claims:
1. In a centrifugal governor, the combination with a shaft, a yoke attached to said shaft, a movable sleeve and a spring housed therein to hold said sleeve in normal position, of balls having arms pivoted to said yoke, independent of but adapted to engage and move said sleeve against the action of said spring, substantially as specified.

2. In a centrifugal governor, a bifurcated frame, a shaft journaled in said frame, having a reduced portion, forming a shoulder thereon, a movable sleeve bearing on the reduced portion of said shaft and having a recess therein bearing on the larger portion of said shaft, a spring in said recess bearing against the shoulder of said shaft, a yoke attached to said shaft, balls having arms pivoted to said yoke and adapted to bear against one end of said sleeve and a pivoted lever adapted to contact With and be moved by said sleeve, substantially as specified.

3. In a gas-engine, the combination with a centrifugal governor having a bifurcated frame, a shaft journaled in said frame having a reduced portion forming a shoulder thereon, a movable sleeve bearing on the reduced portion of said shaft and having a recess therein bearing on the larger portion of said shaft, a spring in said recess bearing against the shoulder of said shaft to hold said sleeve in its normal position, a yoke attached to said shaft, balls having arms pivoted to said yoke and adapted to bear against one end of said sleeve to move the same in one direction, of a supply-valve, an intermediate movable member of the operating mechanisms for said valve, a spring to hold said movable member in its normal position, and a pivoted lever, one end of which contacts with one end of and is moved by said sleeve when said sleeve is operated by said balls, the other end of said lever contacting with said movable member, whereby said movable member is thrown in and out of engagement with said operating mechanisms, substantially as specified.

4. In a gas engine, the combination with the movable member of a centrifugal governor a supply-valve and an intermediate movable member of the operating mechanism for the supply-valve, of a pivoted lever, the respective ends of which contact said movable members and an adjustable pivot for said lever to regulate the speed of said engine and take up the wear in the operating parts, substantially as specified.
764,712 Jul. 12, 1904 Friction Clutch Henry S. Credlebaugh Springfield, Clark County, OH Abstract:
Our invention relates to improvements in clutches, and particularly to clutches of the friction type, the object of our invention being to provide a clutch in which the power which drives the parts can be utilized to throw the clutch members into engagement with each other and also to provide means by which only the minimum amount of movement of the parts is required to engage and disengage said clutch members.
