' IMPROVEMENT IN HORSE-RAKES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE DEAL, of Wilmot, in the county of Stark, and State of Ohio, have invented an Improved Horse-Rake; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification- Figure 1 being a plan of the rake, V

Figure 2 a side elevation thereof, the near wheel being removed to show the working parts more clearly.

Like letters designate corresponding parts in both figures.

The rake is supported by two wheels, A A, and their axle B, and is steadied and guided by thills C C, as

usual with this class of rakes. The driver sits on a seat, E, to direct the horse'and manage the rake.

The first feature of my invention consists in mounting the tooth-roller D on arms I I, which are hinged, at G, to supports a a over or upon the. axle B, and extend forward therefrom, substantially as represented, so that I am enabled thereby to bring the points a: :c of the rake-teeth L L nearly or quite vertically under the axle or centre line of supportr- This arrangement causes the points of the, rake-teeth to rise and lower with the wheels as they ascend over knolls, ridges,'and obstructions, or sink into hollows and depressions, so that the teeth run about as closely and uniformly over uneven asseven ground, without encountering obstructions. The forward ends of the hinged arms are adjusted up and down by set-screws H H, arranged as represented, or in any equivalent manner, for the purpose of raising and lowering the tooth-roller, and ccnsequentl'ythe front ends of the teeth, as may be desired. The centre of motion on which this adjustment is made is in the line G Gr, situated nearly in a vertical positionover the points of the teeth, so that the adjustment of the teeth does not throw them out of proper position. The front ends of the rake-teeth are bent upward around the toothroller D, or attached thereto in any suitable manner, and the said roller turns in its hearings in or on the hiuged arms I I. Back of the centres G- 'G of the arms I I, the teeth-areall supported and lifted by a transverse bar, S, which may also be connected with the tooth-roller D by rods r r, figv 1. The teeth are respectively secured in place .on thebar S by staples or .loops 8 s, which allow some play of the teeth separately, when they strike obstructions, while their elasticity ordinarily keeps themdown in the proper position for action. 7

The second feature of my invention consists in an improved lookingdevice, to keep the liftingbar S down, for holding the teeth in op eratingposition. The general construction ofthis'device is not essentially difl'erent from others heretofore used.

There are one or two pairs of arms, N O, N O; tlre arms NN being pivoted at b b to a cross-bar, f, attached to the thills C G, or toany fixed or firm part of the rake-support, and the 'arms 0 0 being pivoted at c c to N O, N O-are nearly or exactly in line with each other, the rake-teeth are held down in position, as indicated by black lines in fig. 2, but when the arms are bent forward, as indicated by red lines in the same figure, the

teeth are raised fromtho ground, to release them from the gathered hay, or so as to allow the rake to be drawn from place to place. .Ordinarilythese arms are locked by bringing their pivot-connections d d a little'below the direct line, beneath the pivot-points dag-and stopping their further descent by some arrangement; and, with devices heretofore invented, it is necessary to bring the pivot-centres d at below said lines, in order to secure thelocking, since'the'resisting pressure of the teeth acts directly to force the arms upward, unless they fall below the dead-point lines. The'same action causes the lock to bind forcibly, as soon as the-arms fall below the dead-points, so that it is hardto unlock them., I

By my invention, the arms 0 O (which are represented as forked, or double, so as to embrace both sides of the arms N) extend forward beyond the connecting-pivots d, along the arms N N, well toward the forward ends thereof, substantially as represented, and have stops (or, if double, stirrup-connections) g g, to rest on the said arms N N, and permit each pair of arms N O to descend exactly in a line with each other,'and no further. This position, exactly on the dead-points, or all the pivot-centres 0 db in astraight line, when the arms overlap, as described, locks the arms down, since the resisting pressure of the'rake-t eeth, lifting on the rear ends of the arms 0 O, as they turn upward around the tooth-roller D, the centre of which is situated further forward than the rear ends of the said arms 0 O, or so that the teeth make an acute angle withlthe arms, produces a depressing action on the forward, ends thereof, around the pivots d 01, thereby holding the arms N N down, without passing below the dead-point; and, on the other hand, the arms are unlocked readily, since there are no dead-points to lift them past. This overlapping of the arms also strengthens their connections, and prevents sagging. These arms are also self-looking by their weight. Gne'(or, if desired,both) of the aims N N has a lever-handle, P, projecting upward, by which to actuate the arms. There are d ifl'erent'pivot-holes, e e, in the arms N N, or O O, or both, for receiving the pivot-pins cl d, in order to lengthen or shorten the distance between the cross-barf and standards R R, and thus vary the height of the rake-teeth at .pleasure. When the arms N O are bent, and the rake raise l, they are held up by a hook, T, which is hinged to the crossbar f, and

hooks into or around one of the standards RR, as represented in fig. 2, or by anyeqnivalent means. A pedal or foot-lever, K, may be attached to the tooth-roller D, for raising or holding up the teeth by the feet, ifdesired; and counter-weights, Q Q, may be seonred on arms projecting forward from the tooth-roller, so as to partially balance the rake-teeth, and render them easy to raise.

- What I claim asmy invention, and desire to secure by Letters Patent, is- I The combination and arrangement of the hinged arms I I, adjusting-screws H H, or their equivalent, toothroller D, and rake-teeth L L, substantially as and for the pnrpose herein specified.

I also claim the locking-arrns N O, overlapping as described, in combination with the rake, arranged in relation to said arms substantially as and forthe pnrpose herein specified.

The above specification of-my improved horse-rake signedby me, this 31st vday of Angnst, 1867.
