IMPROVEMENT IN HORSE-RAKES.

Spectjcaton forming part of Letters Patent No. 30,010, dated September 11, 1860; reissue No.

3,213, dated November 24, 1868.

To all whom it may concern Be it known that I, DANIEL STRocx, of Chambersburg, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Horse-Rakes and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had t'o the accompanying drawings, forming part of this specification, in which- Figure 1 represents in perspective a horserake embracing my improvements, the lines showing, the relative position of the parts when the crop is being gatheredy by the rake, while the lines represent the attitude assumed by the raking mechanism when elevated for the purpose of discharging the gavel, orto facilitate the transportation of the machine; and

Fig. 2 represents, in perspective, a device for v securing the teeth of the rake-head in such manner that they may readily be removed or replaced.

Similar letters ot' reference indicate corresponding parts.

Horse-rakes may be divided into two classes, the rst of which consists of those in which one or more series of teeth are secured upon a rotating` shaft, and the second of those in which a single series of teeth, having a vertical reciprocating movement, are attached to a rake-head. This latter class is again suscep- `tible of division into two varieties, in one o f which the teeth are all rigidlyv secured to the rake-head and move withit, whilein the other' the teeth are arranged upon the rake-head in such manner that each tooth of the seriesy is capable of moving independently both of lthe rake-head and of its fellows.

The freedom of movement and consequent facility of adaptation to the varying circumstances under which a horse-rake is required toact, possessed by this variety, give it many advantages over the former, and it is to this variety that my improvements are chiefly applicable.

The object of my invention is to provide a cheap, simple, and eiicient implement, adapted to the varying Wants of the farmer; and my improvement consists in 'arranglng the rakehead and straining-frame (of which latter the pressure-bar forms a part) in such relation to each other that the rake-head shall occupy a positionl near the center of the strainingframe, the two being united together and rotating upon the same axis, by which arrangement the construction of the machine is simplitied and many advantages attained in its operation, as hereinafter more fully set forth.

To accomplish these objects I mount an axle (having thills which supportl the platform for the drivers seat inserted into it) upon two wheels, which turn on their axle like those of a common cart, which, in fact, this part of the machine very much resembles'.

Two horizontal beams `extend backward from the axle, one near each wheel, to support two vertical standards in which the rake-head is pivoted. The pressure-bar is suspended from the rake-head by means of radius-bars, which allow it to oscillate freely on its axis.

-This pressure-bar is suspended in very nearly the same level as the axle of the machine, and

forms part of an oblong frame which I call the strainin g-frame, to the upper bars of which are attached the springs which control the teeth. The rake-head, therefore, forms the center of oscillation of this frame as well as of the pressure-bar.

Rake-teeth of any proper form are inserted into sockets on quadrant -levers (pivoted at their front end to the rake-head,) and held in place by means of a pin inserted into the socket at a right angle to the tooth, which latter can readily be removed from or replaced in its socket by removing-the pin.

Upon the top bar of the straining-frame a series of springs formed of short cylinders of india-rubber are placed, there being one for each tooth.

A rod passes down' through the center of each cylinder and the top bar of the strainingframe to about the level of the rake-head.

The upper end of each rod is tted'with an adj ustin g-screw to regulate the strength of the spring, and to its lower end 'a strap is atsuitable springs L, adjustable rods l, tighten- I, substantially as and for the purpose `deing-nuts l1, straps l, and quadrant-levers I, scribed.

for holding the rake-teeth and regulating their tension, substantially as and for the purpose Y DANIEL STROUK' described. Witnesses:
