GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 445,178, dated January 27, 1891.

Application filed August 4,1890. Serial No. 360,849. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL S. HENRIE, a citizen of the United States, residing at Three Rivers, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Governors; and I 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 to which it appertains to make and use the same.

My invention has special reference to that class of governors adapted to be used to regulate the speed of small motors, such as treadmills, animal-power, gravity-power, (be.

The object contemplated is to provide a simple, cheap, strong, and elfective governor which will prevent accidents arising from eX- cessive speed in such motors with which it may be connected, such as motors for pumping water with an ordinary hand pump, churns, (be; and with this purpose in view my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a longitudinal section of my complete device; Fig. 2, a transverse section through line or x of Fig. 1, and Fig. 3 adetail view of the pawl-and-ratchet mechanism.

My governor is attached to a shaft a, mounted in bearings r r, adapted to be connected with any suitable motor. This shaft is provided with a driving-disk 11, secured to rotate with the shaft. This disk drives an oblong rotary head 0 through the medium of pawls (Z, hinged to the driving disk or wheel 7), and a ratchet f, formed upon a sleeve g integral with said head 0. hen using animal-power, tread-mill, &c., where the power is continuous, the driving-disk Z), pawls (Z, and ratchet f can be dispensed with and the oblong head 0 keyed fast to shaft A. The ratchet device is only used to facilitate the winding up of the weight when gravity-power. is used. The oblong rotary head 0 runs loose upon the shaft a, and is provided with a longitudinal way 72 extending transversely to the axis of the head and containinga reciprocal sliding check-bar 1, said bar being movable transversely to the shaft by means ofacam hereinafter described, said check-bar having an elongated slot 3 which permits it to have a limited cndwisc movement across the face of the head. This check-slide is made longer than the head, in order that one end will always project beyond it and engage stop it, rigidly secured to a projection on the casing t. The projecting end, which I will, for convenience, call a dog, is provided with a cushion Z to overcome the shock of coming in contact with the stop 76. A balance-wheel n is fixed upon the sleeve 0 of an eccentric cam 1, which cam reciprocates the sliding check 6 by coming in contact with the anti-friction rollersj, fastened to the face of the sliding check-bar. The edge of the cam is provided with a re cess a; to intermittently receive the rollers j, for the purpose hereinafter set forth. A crank-pin 8 projects from the side of the flywheel, by which the latter is connected with any suitable mechanism. The cam, the reciprocating sliding check, the rotating head, the driving-shaft, and pawl-and-ratchet mechanism are all inclosed within the casing t.

The preferred construction of my device having been set forth, I will now proceed to describe its operation. \Vhen power is applied to the shaft a, so that it moves in the direction indicated by the arrows, it actuates the drivingdisk Z), which imparts motion to the loose head 0 through the medium of the pawls (Z and ratchet f. As the head a revolves it carries with it the sliding check-bar '1', the lower end of which is projecting beyond the end of the head a, and as this end advances it strikes the stop it, and the shock is made easy by the rubber cushion Z. The end of the slide remains resting against the stop, while the balance-wheel, which continues to revolve, brings the cam around so that its periphery will engage the lower anti-friction roller j upon the sliding check-bar and move it clear of the roller, thereby liberating the head 0, and at the same time causing the upper roller to drop into the recess 20 in the back of the cam. The momentum of the fly-wheel drives the cam forward again another half-revohr tion, whereupon the operation just described will be repeated. Hence it will be seen that while the main shaft a is intermittently stopped and started, the balance-wheel, which is actuated by any suitable power, is given a continuous and uniform speed.

The advantage of my device over those in common use is that the main shaft is made to come to a dead stop each halfsrevolution, thereby preventing the mechanism from getting under too great headway and causing accidents and trouble.

It is evident that many slight changes which might suggestthemselvesto a skilled mechanic could be resorted to without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the precise construction herein shown.

Having thus described my invention, what I claim as new,and desire to secureloy Letters Patent, is

1. In a governor of the class described, a rotary shaft having a head secured to rotate therewith, in combination with a reciprocating check-bar having its opposite ends arranged to alternately project beyond the edge of the head, and a cam and continuously-rotating balance-wheel adapted to intermittently actuate the bar to check and release said. head and shaft, in the manner and for the purpose substantially as described.

2. In combination with a rotary shaft having a driving-disk secured to turn therewith, a head loosely mounted upon said shaft and actuated by pawls upon said disk, a reciproeating check-bar arranged across the face of said head, anti-friction rollers upon said bar, a cam mounted loosely upon the shaft and located between the rollers so as to actuate the slide, and a balance-wheel arranged to turn with the cam, all adapted to operate in the manner and for the purpose substantially as described.

In a governor, a shaft having a reciprocating slide mounted thereon and movable at right angles to its aXis, in combination with an actuating-cam secured to rotate loosely upon said shaft and carrying with it a balance wheel'having a continuous motion, whereby the shaft is intermittently stopped and started, in the mannerand for the purpose substantially as described.

4. The combination of a driven shaft having a driving-disk secured to rotate therewith, a loose head provided with a reciprocating check-bar having its opposite ends adapted to alternately extend beyond the radius of the head, and a rotary cam having asleeve carrying a balance-wheel secured to rotate with the cam, in the manner and for the purpose substantially as described.

5. In a governor, a shaft, in combination with a reciprocating check-bar and a cam so arranged that the one alternately actuates the other, in the manner and for the purpose substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

, DANIEL S. IIENRIE.
