UNITED STATES PATENT OEEIC.

J. M. RANDLE, OF BRIGHTON, ILLINOIS, ASSIGNOR TO HIMSELF AND J. W. HILL, OF SAME PLAGE.

IMPROVED HORSE-POWER.

Specification forming part of Letters Patent No. 53,378, dated March 20, 1866.

To all whom 'it may concern:

Be it known that I, J. M. RANDLE, of

` Brighton, in the county otMacoupin and State of Illinois, have invented a new and useful Improvement in Horse-Powers t'or Hay-Derricks or other similar uses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure l of the annexed drawings is a perspective view of one of the improved horsepowers. Fig. 2 is a plan ofthe same. Fig.3 is a transverse vertical section ot` the machine through its axis, and Fig. et is a sectional elevation ot` the clutch-post which forms the journal for the rim-wheel.

This invention consists in making a horsepower in such a manner that it can be unshipped by a man at some distance from itfor instance, on top ot' a load ot hay in the case ot' a hay-derrick.

A Vis a foundation frame-work, upon which the other parts are erected. B isa vertical journal erected upon A, upon which the metallic hub O rests and around which it revolves.

C is a horizontal wheel rmly attached to the hub C, and provided with a flange, c, around the lower edge of its periphery, to keep the draft-rope D from ruiming oft at the bottom.

E is a vertical post, in the lower end ot' which is a cylindrical cavity, with the threads of a female screw cut therein that fit the screw-threads e on the upper end ot' the journal B.

E is a ring, with clutch-joints d on the lower end of it, that lit into the clutch-joints d on the upper end of the hub O when all the parts are together and in operation. rlhe clutchring E is placed on the lower end of the post E in such a manner that it may receive a slight vertical motion sufficient to raise the clutches I out of the clutches d.

The curved metallic arm E3, projecting from 011e side of the postgE near its lower end, furnishes atV orV a fulcrum for the lever E2, which is connected with the clutch-ring E by means of two pins, that enteri a groove made around the periphery of the clutch-ring, so that said ring may revolve around the post E without the pins x stopping its rotary motion.

A cord, E, is fastened to the lever E2 near its outer end, from which point ot' attachment it passes up in a diagonal direction to a mortise made for its passage through the top end of the post E, and from thence it passes on to the location of the operator, which, in the case of a hay-derrick, will be on top of the load of hay.

When the operator draws up the cord E4 it will raise the long arm ot' the lever E2 high enough for the pins x to elevate the ring E sufficiently to allow the clutches d to become disconnected from the clutches d', thereby affording a very economical and effective shipping and unshipping arrangement tor that 'class ot' horse-powers which are suitable for hay-derricks.

Au iron arm, G2, has an annular end which surrounds the upper end of the hub C, and there are clutch-openings d', similar to those in the upper end ot' the hub C, made in the upper part of this annular end.

When the clutches d are down they enter the clutches d in both the lever C2 and the hub C, and so couple all these parts together.

The motive power is to be attached to the outer end of the lever O3, the inner end of which is trmly secured to the arm C2.

One end of the draft-rope D is trmly fastened to the periphery of the wheel C', from which point the other end is conducted out through the timber-head A', where it should pass over a sheave, (not shown,) and then be attached to the wei ght to be raised.

The machine, constructed as above described, and the horses attached to the outer end ot' the lever C3, when the team has turned the wheel O far enough around to take up a sufficiency of the rope D to raise the Weight (not shown) attached to its outer end to the required elevation, the operator will draw the cord E, which will, as has been shown, disconnect tlic clutches d and d', and so stop the motion of the (.lrat't-rope D instantly, although the team may continue to advance.

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

The combination of the wheel C', arm C2, lever O3, and journal B with the post E, clutch-ring E', lever E2, and ropes D and E4, when constructed and arranged as and for the purpose set forth.
