To all 'whom it may concern:

Be it known that I, T. G. PALMER, of' Shultzville,

in the county of Dutchess, and State of New York,

have invented new anduseful Improvements in Brakes forHorse-Power for threshiug-maohines and other like purposes; and I do hereby' declare that the following is a full and complete description of the con.V

struction of the same, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figure 1 is a side view of a horse-power, with the driving-wheel, belt,and brake in position;

Figure 2 is atransverse section, showing the brake; lever resting uponthe hinged support, which forms a part of the trigger; and

Figure 3 is a transverse view ofthe lever, after the trigger has been caused to fall, by the action of the belt, and the brake brought into action.

The horse-power is ofthe ordinary kind, having an endless belt provided with wooden lugs, and rest-ing upon friction-wheels.

A represents the driving-wheel, and

B represents the belt, which passes around the pulley ofthe threshing-cylinder or other shaft to be driven. This belt may be open or crossed, as its action upon the trigger will be the same in either onse, as will be fully shown.

C represents the lever of the brake, and

D represents the rubber which acts upon the drivingfwheel A.

E represents a hinged support for the lever C of the brake. The inner end of this is hinged by a staplebolt to the frame of the horsepower, in such a position that the belt, when thrown olf from the pulley G of the threshing-cylinder, will pass a little above and in front of it. The outer end of this support is formed into a hook, as shown at E, figs. 2 and 3.,

.F represents a trigger, which is secured tothe frame,

just below the bolt that secures the support E to the frame, the trigger' being long enough, when extending horizontally, to reach beyond the belt, as shown in figs. 2 and 3. It is bent in the middle, as shown, and provided on the upper side of theobtuse angle with a sharp'noteh, into which the hooked end ofthe support E accurately its. When the trigger is set, it has the position shown in gs. l and 2, thearm C ofthe brake resting with its weight upon the ,support E, the outer end ofthe trigger F being horizontal alittle distance below the belt B, as shown inl iig. 2. Now, while in this position, if the belt, from any cause, be slipped from the pulley, it would fall upon thetrigger, and move it forward in the direction of the running of the belt,.and in doing so would release the support E,

bringing the parts E 'F C into the respective positions lshown in fig. 3, and thus bring the rubber D into iirm contact with the periphery of the driving-wheel A, and by this means put aA stop to the motion of the horse-power.

It is obvious that the belt can run in either direction, either open er crossed, and the same results would follow:

What I claim as my improvement, anu desire to secure by Letters Patent, is

The herein-described'brake-combination, consisting of the. lever C, rubber D, support E, and'tri ger F, or their equivalents, all constructed and arranged as and4 for the purpose specified.
