AUTOMATIC FRICTION-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 600,497, dated March 8, 1898.

Application filed May 11,1897. Serial No. 636,020. (No model.)

To all whom, it may concern:

Be it known that we, CYRUS MOORE and PERRY SAVILLE EST, of Perry, in the county of Shiawassee and State of Michigan, have invented a new and Improved Automatic Friction-Governor, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved governor which is simple and durable in construction, very effective and automatic in operation, and designed for use on windmills, engines, and other machines and apparatus.

The invention consists principally of a friction-rim, one or more brake-blocks adapted to move in engagement with the inside of the said rim, levers fulcrumed on a wheel turning with the shaft or other movable part of the machine on which the device is used, and a loose spring-pressed device connected with the said levers to cause the same to swing simultaneously inward or outward.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a transverse section of the same. Fig. 3 is a face view of part of the rim. Fig. 4 is a perspective View of the diskarm. Fig. 5 is a perspective view of the tension device for the disk. Fig. 6 is a side elevation of the connecting-rod between the disk and levers, and Fig. 7 is an enlarged perspective view of one of the brake-blocks.

On the shaft A or other movable part of the machine on which the device is applied is secured a wheel B, on the web of which are fulcrumed at O a series of levers O, each carrying at or near its free end a weight D. Each of the levers O is pivotally connected by a link E with a brake-block E, arranged close to the inner surface of a rim 1?, having lugs F for fastening the said rim to a support, such as the frame or other stationary part of the Each brake-block E is pivotally connected by a link E with the wheel B, so that the blocks are held in proper position in notches cut in the rim or web of the wheel B. The free end of each lever O is pivotally connected by a rod G with a .disk H, mounted to rotate loosely either on the shaft A or on the hub of the wheel B, as illustrated in the drawings, and on the said disk II is secured an arm H, pivotally connected with a tension device, consisting of a rod I, pivoted on the arm H and fitted to slide near its outer end in a bearing .I, attached to the wheel B. A spring K is coiled on the outer end of the rod I and rests with one end on the bearing J and at its other end is engaged by a thumb-screw I, screwing on the extreme outer end of the rod 1 to regulate the tension of the said spring, and consequently the pressure on the arm H and the disk II. The free end of each brakeblock E is provided with a lug E fitted to move in a guideway or recess formed in the web of the wheel 13, as illustrated in the drawlngs.

The operation is as follows: \Vhen the shaft A is rotated, the wheel B moves with it, and when. the speed of the shaft increases beyond a normal rate the weighted levers O swing outwardly by centrifugal force, whereby the brake-blocks E are moved in frictional contact with the inner surface of the rim F, so that a braking of the wheel 13 takes place, and consequently the speed of the shaft A is reduced. WVhen the levers O swing outward, the rods G pull on the disk H, so as to turn the same in the direction of the arrow (1, whereby the arm H pulls on the rod I against the tension of the sprink K, and when the speed of the shaft has decreased to its normal rate then the levers O swing inward again to move the blocks E out of engagement with the rim F, and this motion of the levers is accelerated by the action of the spring K on the rod I drawing the disk H back to its former position. It will be seen that this device is very simple and durable in construction, can be readily applied to various machinery, such as windmills and the like, and is not liable to get out'of order.

Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent 1. An automatic friction governor, comprising a fixed rim, a fixed part on the shaft or other movable part of the machine on which the governor is used, weighted levers fulcrumed on said part, brake-blocks pivoted to the said weighted levers and part, and a spring-controlled device connected with the said levers for accelerating the return of the same to a normal position, substantially as described.

2. An automatic friction-governor, comprising a fixed rim,a plurality of brake-blocks, adapted to move in engagement with the inside of the said rim, a part fixed on the shaft or other movable part of the machine on which the governor is used, levers fulcru med on the said part and pivotally connected with the said brake-blocks, a loose disk pivotally connected with the said levers, and a tension device for the said disk, substantially as shown and described.

3. An automatic friction-governor, comprising a fixed rim, a plurality of brake-blocks adapted to move in engagement with the said rim, a wheel secured on the shaft or'other movable part of the machine on which the on the said wheel and pivotally connected with the said brake-blocks, a loose disk concentric with the said wheel, links connecting a to return the same to a normal position, substantially as shown and described.

4. In an automatic friction-governor, the combination with a fixed rim, and a wheel mounted to revolve, of weighted levers pivoted to the wheel, and brake-blocks pivoted to the said wheel and levers, substantially as described.

5. In an automatic friction-governor, the combination with a fixed rim, and a revoluble wheel having notches and guideways in its rim, of weighted levers pivoted to the wheel, brake-blocks in the notches of the wheel and provided with lugs fitted to move in the guideways of the wheel, 'a link pivotally connecting the blocks to the rim of the wheel, and

- links pivotally connecting the blocks to the levers, substantially as described.

6. In an automatic friction-governor, the combination with a fixed rim, a revoluble wheel, pivoted levers, and brake-blocks carried by the levers, of a loose disk, an arm secured to the disk, a bearing on the wheel, a

, rod secured to the arm working in the said bearing and provided with a thumb-screw at its end, and a spring on the rod between the bearing and thumb-screw, substantially as 5 described.

governor is used, weighted levers fulcrumed CYRUS MOORE. PERRY SAVILLE WVEST.
