HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 314,622, dated March 31, 1885.

Application filed December 14, 1883.

T0 aZZ whom it may concern.-

Be it known that I, E. FOWLER Sronnnnn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Horse Hay-Rakes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawingsfiorming a part of this specification.

My invention relates to an improvement in horse hay-rakes of that class known as selfdump rakes, in which the traction of the wheels is employed at the will of the operator to elevate the teeth and discharge the collected loads, and this while the machine is either going forward in a straight line or is in the act of turning in either direction.

It also relates more particularly to that class of rakes which have been long and favorably known to the trade as Hollingsworth rakes, which are merely hand-dumping rakes, and are chiefly distinguished from other rakes by and derive their principal merit from having the teeth attached to a rocking frame consisting of two or more parallel bars supported upon arms pivoted to the axle, and with the teeth adjustably pivoted, so as to be capable of forward and backward adjustment to accommodate them to light or heavy raking, at a point between the bars of the rocking frame or rakehead and in line with the oscillating axis of said rocking frame. The most desirable manner of attaching the teeth in this class of rakes is by means of thimbles journaled or strung upon a rod or shaft just over the axle, which rod serves not only as a pivotal bearing for the teeth, but also for the side arms of the rocking frame, which are mounted and journaled thereon. y

The object of my present invention is to render rakes of this class self -dumping by means of pinions revolving with the carryingh ls, other pinions or segmental pinions seur d to the arms of the rocking frame cont i ith the oscillating axis of said frame, a d i t mediate pinions meshing with said gm ntal pinions, which at the will of the operator can be made to engage with the pinions upon the carrying-wheels, to effect a locli (No model.)

between the carrying-wheels and rocking frame, which, as the machine advances or turns, causes the tilting of said frame and the elevation of the teeth.

The novelty of my invention consists in the construction and-combination of the parts, as will be herewith set forth and specifically claimed.

In the accompanying drawings, Figure 1 is a side elevation of a rake embodying my in-' vention with one of the carrying-wheels re moved and the latch and detent omitted and with the teeth down at work. Fig. 2 is an enlarged end elevation, showing the operating mechanism for effecting the lock between the carrying-wheels and rakehead in position when the teeth are at work gathering a load.

Fig. 3 is a corresponding view showing the positions of the parts just after the lock has been effected. little more than half of the axle, showing the relative position of the parts thereto attached.

The same letters of reference are used to indicate identical parts in all the figures.

A represents the axle provided with spindles, upon which the carrying-wheels B revolve. Secured to this axle are the customary thills, O, with cross-girts D, supporting the seat-beam E, to which is attached the drivers seat F.

Therockin g frame or rake-head is composed, preferably, oftwo front bars,G, between which are secured the spring-supports H for the forward ends of the rake-teeth, and a rear staple bar, I, said bars being connected at their ends by the arms J, which are journaled at or near their middle upon a shaft or rod, K, above and extending the length of the axle, and mounted in suitable standards or bearings, L, extending up from and attached to the axle.

The teeth M, of the shape shown, after be ing passed through the staples in the rear bar, are adjustably clamped in thimbles or eye bearings, one of which is shown in dotted lines, Fig. 4, which are journaled upon the shaft K in the usual or any suitable manner, and have their forward projecting ends supported by the usual or any suitable spring- Fig. 4 is a front elevation of a 1 guides, H, connected to the front bar or bars of i the rocker-frame.

ICO

At or about the middle of the rocker-frame is secured the lifting-arm N, which, attached to both the front and rear bars of the rockerframe, serves as means of connection for the usual hand-lever, O, as shown in Fig. 1.

This much of the rake constitutes the ordinary hand-dump rake of the Hollingsworth class.

Now, to render this rake self-dumping, I employ the following instrumentalities:

Attached to or formedwith the inner ends of the hubs of the carrying-wheels are pinions P, which continually revolve with the carrying-wheels, and suitably fastened to or formed integral with the arms Jon their outer sides, directly over the pinions P, and concentric with the oscillating axis of the rockerframe, are segmental racks or pinions Q, which, however, do not mesh with the pinions P.

Just outside of the racks Q and hung loosely upon the projecting ends of the shaft K, or upon spindles in line with said shaft, or upon other spindles slightly out of line with said shaft, are short rearwardlyextending arms R, to the inner and lower ends of which are journaled the intermediate pinions, S, which mesh with the segmental pinions Q at all times, but only with the pinions P when it is desired to dump the rake by its own traction.

, Extending along the front of the axle and secured in suitable bearings is a rock-shaft,

T, to the outer projecting ends of which are rigidly secured. crank-arms U, which extend back under the arms R, and have, preferably, friction-rollers a secured to their rear ends, which bear against the arms R.

Keyed or otherwise rigidly fastened to the rock-shaft T, preferably at or near its middle, is a pendent arm, b, from the lower end of which a chain, cord, or pedal mechanism extends and is attached to the seat beam or frame within ready access of the drivers foot.

Through a perforation or slot in the arm 7) is passed the front end of a bolt, 0, which extends back through the axle, which is eounterbored from its rear side, as shown particularly in Figs. 2 and 3, to receive a spiral spring, d, which, encompassing the bolt, bears at its front against the front wall of the counterbore, and at its rear against the head of the bolt, as shown. The tension of this spring may be adjusted by a nut, e, upon the front end of the bolt bearing against the arm I), as will be readily understood.

The purpose of the spring-bolt just described is to hold the arm I) in such position that the.

arms U will hold up the arms R, and thereby keep the intermediate pinions, S, disengaged from the pinions P, as shown particularly in Figs. 3 and 5, and also to retract the rock-shaft T, and raise the pinions S when the lock has been broken. Also keyed upon the rock-shaft Tis a downwardly-projecting slotted detent, f, directly under the'lifting-arm N. Through the slot'projects the forwardly-extending latch 9,

which is pivoted to the axle. as shown, has near its forward end a locking-notch on its under s'ide,'and is preferably forced down by any suitable spring, h, interposed between it and the axle.

The end or nose of the latch may be rounded or beveled, as shown, and the arm N has an- From this construction it will be readily understood that when the driver wishes to dumpthe rake he merely presses his footnpon the chain, thereby drawing forward the arm b, and turning the rockshaft T, which. as it turns, throws forward the detent f until the notch in the latch g engages it, and thereby holds theroek-shaft T locked. This turning of the rock-shaft throws down the arms U and permits the arms R, with their attached pinions, to drop, so that said pinions S come into mesh with said pinions P.

that in said figure the tilting of the rake-head is nearly completed, and the revoluti in oft-he pinions P is imparted, through the intermediate pinions, S, to the racks Q, in such manner that the rocking frame or rake-head is tilted forward, and the teeth thereby elevated. This tilting forward of the rocking frame or rakehead continues until the roller 6,. upon the arm N, or any other suitable striking device on said arm or rocking frame,come s in contact with and lifts the latch thereby freeing the detent, and releasing the rock-shaft T, which, through the retraction of the spring cl, acting upon the arm I), is so turned as to raise the arms U, which carry up the arms R, thereby lifting the intermediate pinions, S, outof gear with the pinions P. In case the spring d should prove insufficient to turn back the rock-shaft T and effect the disengagement of the pinions S and 'P, the roller 1' would come in contact with the detentf, and, forcing it back, would thus exert the tilting force of the rake-head directly upon the rock-shaft T to cause the raising of the arms U and disengagement of the pinions S and P, as will be readily understood, and the rocking frame being thus released drops back with the teeth to a raking position.

It will be seen from this construction, and from the fact that the arms P are loosely pivoted, that, should the rake be in the act of turning in either direction, the self-dumping would The parts are now in the position shown in Fig. 3. except.

take place just the same from the wheel trav- Should the spring (2 and the pressure of the rolleri upon the detent f prove insufficient to turn the rock-shaft T to lift the arms U and effect the disengagement of the intermediate pinions, I provide forward extensions, j, to the arms U, so situated that lugs or detents it upon the outer arms of the rocker-frame would press upon the extension j just after the roller '5 had released the latch g and acted upon the detent f, so that any further forward tilting of the rocking frame would be thrown directly upon the extensions 9' of the arms U, and cause them instantly to be thrown up in the rear, to release the intermediate pinions and break the lock between the carrying-wheels and the rocking frame or rake-head. Furthermore, if desired, the arm I) and detent-arm f may be united in one piece instead of being separate, as shown.

As also will be readily understood, in this construction, the shaft K may be dispensed with, and, if desired, independent hearings or pivots for the rake-teeth and the rocking frame may be employed, care, however, be ing taken that their axes are coincident.

The rake herein described is a modified form of the rake described in my application No.1l4,518,filed on the same date herewith,and wherein the power of the carrying-wheels, or either of them, is exerted through the medium of pinions secured to the ends of a shaft which carries the rake-head instead of directly to the side bars of the rake-head.

Having thus fully described my invention, I claim-- 1.' In a horse hay-rake, the combination of the rake-teeth attached to a rocking rakehead, the rocking rake-head having segmental racks or pinions directly and rigidly secured thereto at its ends concentric with the axis of racks or pinions directly and rigidly secured thereto at its ends concentric with the axis of the rake-head, pivoted arms carrying iutermediate pinions constantly meshing with the segment-racks, pinions revolving with the carrying-wheels, mechanism which, at the will of the operator, causes the locking, by means of the racks and pinions, of the carrying-wheels to the rake-head to cause the tilting of the same as the machine advances or turns, and mechanism which, when the teeth have been sufficiently elevated to discharge their load, disengages the pinions and racks and releases the rake-head from the carrying-wheels.

3. In a horse hay-rake such as described, the combination, with the outer arms of the rocking frame, of the segmentpinions Q, rigidly attached thereto, the arms R, intermediate pinions, S, constantly-revolving pinions P, and lifting-arms U, attached to the rockshaft T, with means for rocking and locking said shaft, substantially in the manner and for the purpose specified.
