IMPRVEMENT IN HORSE-RAKES.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom, 'it may concer-n.- i

l Be it known that 1, G. M. L. MCMILLEN, ofDayion,y in the county of Montgomery, and State of Ohio, have invented a new and improved Horse Hay-Rake; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, making a partof this specification, in which Figure 1 is a longitudinal vertical section. i

Figure 2 is a detached side view, a portion in section.

Figure 3 is a top View.

This inventionis a simple, cheap, convenient, and effective device for automatically locking down the teeth so as to hohl them in contact with the ground, while allowing them to be easily raised bythe attend-v ant when occasion may require.

In the drawings- T T indicate the thills;

W, the wheels;v

A, theaxle; and

t t, the rake-teeth, the latterbeing attached to a roeking beam, (or to a rocking axle, if such a construction is preferred in such a manner that they can all be raised or depressed by a single movement of a lever.

L is the lever employed for that purpose, and

R, the connecting-rod, through which the movement is communicated from the lever to the rake-head, roel;- ing beam, or axle. i

The Vleveris bent inthe form clearly shown in fig. l, so as to apply the` power properly fto the rake-head, while adapting the lever to the spring-catch and lever hereinafter described.

Thus constructed, the lever is pivoted, at p, to one of the `tl1ills, behind tlie\vliifiletree, or to a supporting-bar provided for the purpose;'and a right-angled lever, M, pivoted at m to a supporting-bar 0, is em'- ployed in` connection with it, in the manner which I will now describe.

l .Said lever M combines in itself a spring-catch and atreadle, the catch or latch being shown at 0the spring arm of the lever, and prevent ythe latter from' being depressed, and the teeth from being raised.

The spring is to operate the catchautomatically, so

that the attention of. the driver will not be required to l lock the teeth down.

The treadle is to enable the driver to conveniently disengage the latch from the lever by a single move- 1 'ment of his foot, thereby leaving the teeth free to rise. l

4rBy a slight pressure upon the lever M at the pointu, the lever is rocked on its axis rn, the catch e is withdrawn from the lever L, and the teeth t tcan beraised at will Upon' removing the root from thepart fu, the spring s operates to restore the lever M to its former position, and when the lever L resumes its place, it is locked automatically by the spring-catch, in a manner that can beclearly understood from figs. 1 and 2L The whole apparatus is very simple, cheap, and conv venient of-operatiom and can readily be applied to v rake are raised and depressed, when constructed in any other manner than as herein shown; but v What I do claim as my invention, a d desire to secure by Letters Patent, is-

Thedevice herein shown and described, consisting essentially of the right-angled lever M, having a spring,

s, under its ange at oneeud, and a snap-catch, c, at y the other end, when constructed and applied to a rake in connection with the lever L, rod R, and teeth t t, as

shown, and employed for the ,purpose herein set forth.
