TOALL WHOM ITVMAY OONCERN:

Be it known that I, C. E. MURRAY, of Sugar Valley, in the county of Clinton, and State of Pennsylvania, have invented a new and improved HorseiRake; 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 malte and use thc same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates toa new and improved revolving wire-tooth horse-rake, and it consists in a peculiar means employed for holding the rake, and revolving the same at proper intervals, in order that it may discharge its load, and also in a certain means to allow a vertical play to the teeth, to admit of them conforming /to the inequalities of surface over which they may pass. A

In the accompanying sheet of drawings* Figure 1 is a plan or top view of n1y,invention.

Figure 2, a side sectional View of the same, tak-en in the linea: a', fig. 1.

Similar letters of reference indicate corresponding parts.

A represents an axle, having a wheel, B, on each end of it, and two arms, C C, projecting from its rear side, to serve as bearings for the rake-head D,'the latter being allowed tolturn freely in the former.

.This rake-head is provided with two sets of teeth, E E', which are constructed of wire, and curved in the -usul form, as shown in g..'2, one'set of teeth projecting from the shaft in a direction reverse to the other set.

On one'end of the rake-head D there is attached a ratchet, F, provided with two teeth at opposite points, and is a pawl, which engages with said ratchet, said pawl working on a pivot at a, and having a spring', Ib, bearing against it, the spring having a tendency to keep the pawl engaged with theyratchet.

The rear end ofthe pawl G is provided with an oblong slot, c, and is connected to a rod, H, by a pin, cl, which passes through the slot c.

The front end of the rod II is attached to an arm, I, 'which is secured to one end of a shaft, J, the latter having its hearings e on a foot-board, K, the rear end of which is permanently secured to the axle A, and the front end supported by spiral springs f, on rods fx fX, attached to the thills L L, said rods passing through the foot-board K, and. serving as guides for the same, as will he fully understood by referring to fig. 2.

The arm I has an eye, y, attached, through which a spring, h, passes.

This spring. is secured to the foot-hoard K', and has a tendency to throw the arm I backward. in the direction indicated by arrow 1, (see fig. `2.)

To the extreme end of the rake-head, near the ratchet F, there is secured a plate, M, having an oblong slot, z', made in it, with a notch or recess, j, at each end of the slot, (see fig. 2,) and N'is a rod, the frontend of which isiscrewed into a har, O, the latter being secured to and projecting'from .the arm I. r

The rear end of the rod N has a pin, It, projecting from it, which passes through the slet z'.

The rake is retained in position by the` pawl G, which engages with the ratchet F, the pawl G, and rod II, holding the arm I forward, and keeping the spring 7L depressed.

While the rake is`thus held or retained in position, the lower set of teeth, E, rake up the hay, and when a suiicient quantity of hay has been gathered by them, the operator, -by pressing his foot upon a troadle attached to shaft J,forces back the rod II, therod N yielding or giving' sufficiently to admit of the rod vII forcing down the rear end of the pawl G, so that the front end of the same will'be raised out from the teeth of ratchet F.

When this is done, the spring instantly forces back the arm I, and the krod N acts against the plate M, turning: it and the rake-head D a half revolution, in the direction indicated by arrow 2, so as to bring the set of teeth E down to a working position, where they are retained by the 'vpawl Gr, which engages with the other teetl of ratchet-F.

After each half revolution of the rake, the arm I is moved forward and the spring h depressed bythe driver actuating a treadle of shaft J, the rod N, by this movement of the arm, heing drawn forward, so that the pin Ic of said rod may catch into the forward notch or recessj, of slot The several parts are then in n condition to ad'mitof another half revolution of the rake "being,r made, when required.

By having thefoot-'nonrd K. resting on springs Connected with the thills, the rake-teeth areallowod to rise and fall, to conform to the inequalities of surface over which they may pass.

By this means the teeth are prevented from being bent or unduly strained.

claim as new, and desire to secure. hy Letters Patent-` 1. The rake, provided with two sets of teeth, E E, and hung at the rear of the axle A, as shown, in coinbination with the ratchet F, pan'l G, rod H, arm I on shaft J, spring L, and the rod N, and slotted plate M, all arranged to operato in the manner substantially as und for the purpose set forth. I

2. The resting of the front end of the foot-board'K on spiral springs f, which rest on the thillsiL L. substantially in the manner as and for the purpose set forth. Y Y

The above specification of my invention signed by me, this 17th day of December, 1867.
