UNITED STATES PATENT OFFICE.

JASPER A. HOUSE, OF EAST BERKSHIRE, VERMONT.

H ORSE-POWER SPEED-REGULATOR.

v SPECIFICATION forming part of Letters Patent'No. 287,327, dated October 23, 1883.

Application filed August 31, 1883. (No model.)

To all whom it may concern:

and having brake-pads g on their outerex Be it known that I, JASPER, A. RoUsE, a tremities.

citizen of the United States, residing at East Berkshire, in the county of Franklin and State of Vermont, have invented certain new and useful Improvements in Horse-Power Speed- Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in devices for preserving uniform motion in horsepowers and preventing liability to accident, which might otherwise result from a sudden increase of speed; and it consists of a loose pulley having a split hub, for greater convenience of adjustment over the wheel-clutch, and a foundation-block provided withweighted arms, and on which two lever-brakes are pivoted, and to which is bolted a leaf-piece, by means of which an adjustable grip is formed, for readyand reliableatt'achment to the wheelclutch between the loose pulley and the drivewheel. The whole forms a speed-regulating attachment which is entirely separate and distinct from the drive-wheel, and so constructed that it can be attached or removed with the greatest convenience.

In the accompanying drawings, in which similar letters indicate like parts, Figure 1 is an elevation showing the relative positions of my speedregulator and the drive wheel. Fig. 2 is a plan view of my device. Fig. 3 is a side elevation of a horse-power, showing the application of my invention. Fig. 4 is a plan view of my foundation-block, with the weighted spring-actuated arms passing through swinging ears and operating brake-pads. Fig. 5 is a plan view of the loose pulley and split hub.

A is the drive-wheel ofahorse-power, which is attached in the usual manner to the arbor B by means of the clutch O.

D is what I term a foundation-block, designed to be rigidly clamped to the'clutch 0, inside of the drive-wheel A, and separate from it, as shown in Fig. 1, by means of the leafpiece E, which is bolted to it at d (I, thus forming an adjustable grip around the clutch, so that it may be readily removed at will. It also forms the support for the weighted arms F and the bell-crank levers G, fulcrumed at e,

H H are swinging ears, through the lipi 011 the end of which the arm F loosely passes. These ears are pivoted to the block D at h, in order that they may more readilyiadj ust themselves to the varying positions taken by the arms F as they move outward and back to place, and thus avoid the tendency to bind the arms to which stationary loops are liable.

J is a regulating-spring coiled around the 7 arm F, between the adj usting-nut j and the lip 45 of the ear H. The arms Fterminate in slotted weights f, which are designed to slide freely on the block D, to which they are loosely attached by the flat-head rivets K. By this construction the arms F are made more sensi tive to the action of the centrifugal force, by which they are carried forward, than they would be if confined to the plane on which they move by fixed loops in the ordinary way.

L is a loose pulley, which is so hung on the clutch 0, back of the foundation-block D, that the brake-pads g g on the outer end of the levers G may impinge upon its rim and control its motion as they are carried forward by the outward movement of the arm F, which is 0011- nected with the other extremity of the lever G. It is provided with asplit hub, M, attached to ears upon its rim at n n, for the purpose of more conveniently putting it on over the clutch 0, without requiring the clutch-key to be removed, whenever it becomes necessary to shift the regulator.

P is a compound lever fulcrumed at p to the frame of the horsepower, as shown in Fig. 3. Its upper end is connected tothe hub M, at r, of the loose pulley L by the rope s, and its lower end to thelever R, pivoted at v, on which a brake-pad, T, is so arranged that as the lever R is raised it is brought in contact with the rim of the drive-wheel A...

In operation the arms F F are set so that the pads g y do not impinge upon the rim of the loose pulley L, and the rope sbeing loose,

the brakepad T is out of contact with the drive- I press tightly against the rim of the loose pulley L. This pulley, no longer loose, is thus compelled to revolve upon the arbor B of the drive-wheel A, thereby winding the rope around its hub M, which draws down the end of the lever P, and at the same time raises the lever B until the brake-pad T is pressed against the rim of the drivewheel. The speed of the drive-wheel is thereby checked until by the re duction of the centrifugal force the weighted arms F F are drawn back by the action of the spiral spring J, and the pads g graised. The pulley L, being thus free from the pressure of the pads g g, againbecomes loose and relieves the rope s from its strain around the hub M, and also the driving-wheel from the pressure of the pad T.

, The degree of centrifugal force required to move the weighted arms F F is regulated at will by varying the tension of the spring J by the adjustment of the nut 5.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

- 1. In a speed-regulator, the combination of levers P and R, combined together and with the drive-wheel A, substantially as shown, and for the purpose set forth.

3. In speed-regulators, the foundation-block D and 1eaf-piece E, by which it may be readily attached to the clutch C, substantially as described.

4. The combination, in speed-regulators, of 40 the weighted arms F,-adjustable spring J,

swinging ear H, and brake-levers G, with the foundation-block D and leaf-piece E, substantially as set forth.

In testimony whereof I do aflix my signa- 45 ture in presence of two witnesses.

JASPER A. ROUSE.
