HORSE HAY-I-RAKE.

SPECIFICATION forming part of Letters Patent No. 314,623, dated March 31, 18185.

Application filed January 11, 1884. (No model.)

To all whom it may concern.-

Be it known that I, E. FOWLER Sronnnnn,

a citizen of the United States, residing at Day ton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Horse Hay-Rakes, of which thelollowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming 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 machine is employed at the will of the operator to elevate the teeth and discharge the i5 collected load, and this while the machine is either going forward in astraight 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-dump rakes, but which are chiefly distinguished from other rakes by and derive their principal merit from having their teeth attached to a rocking frame con- 2 5 sisting of two or more parallel bars supported on side arms pivoted to the axle, and with the teeth adj ustably pivoted, so as to be capable of forward or backward adjustment to accommodate them to light or heavy raking, at a 0 point between the bars of the rocking frame and in line with the rocking axis of said rocking frame. The most desirable manner of attaching the teeth in this class of rakes is by means of thimbles or eye-bearings mounted 5 upon a rod or shaft just over the axle, which rod serves not only the purpose of a pivotal bearing for the teeth, but also for the arms of the rocking frame,which are journaled there- The object of my present invention is, in addition to the functions of the rod or shaft above mentioned, to utilize the same by proper connections to effect the lock between the carrying-wheels and the rocking frame or ral; e- 4 5 head, in order that the traction of the machine may cause the rocking of the rake-head and elevation of the teeth.

The novelty of my invention consists in the combination, with the rake-teeth, the rake head, and carrying-wheels, of an oscillating non-rotating locking-shaft upon which the teeth and rakehead are coincidently journaled, and connecting mechanism whereby. said shaft can be oscillated to effect a lock between the rake-head and the carrying-wheels at the will of the operator, to cause the elevation of the teeth as the rake advances or turns.

It also consists in the construction and combination of the parts, as will be hereinafter 6 set forth and specifically claimed.

In the accompanying drawings, Figure 1 is a side elevation of a horse hayrake embodying my invention with one of the carryingwheels removed. Fig. 2 is an enlarged end 6 elevation of the rake-head, axle, and operating mechanism showing the position of the parts when the teeth are down at work. Fig. 3is a corresponding view, showing the posi' tion of the parts when the teeth have just .about reached their highest point of elevation and the lock between the carryingwheels and rake-head is about to be broken. Fig. 4 is a front view of little more than half of the rake-head and 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, C, with cross girts D supporting the seatbeam E,t0 which is attached the drivers seat F.

The rocking frame or rake-head is composed, preferably,of two front bars, G, between which 85 are secured the springsupports H,for the forward ends of the raketeetlnand a rear staplebar, I, said bars being connected at their ends by the side arms, J, which are journaled at or about their middle upon a rock shaft, K, just 0 above and extending the length of the axle, and mounted in suitable standard-bearings,L, extending up from and attached to the axle.

The teeth M, of the shape shown, after bein g passed through the staples in the rear bar, 5 are adj ustably clamped in the thimbles or eyeloearings, which are strung and pivoted upon the rock-shaft K in the usual or any suitable manner,and have theirforward projecting ends supported by the usual or any suitable spring- I00 the axle A, and from the lower end of which guides, H, connected to the front bar or bars of the rocker-frame.

' At or about the middle of the rocking frame is secured the lifting-arm N, which, attached to both the front and rear bars of the rockerframe, preferably encompasses the rock-shaft K;.and the usual hand-lever, 0, Fig. 1, is attached to the forward end of this lifting-arm N by suitable connecting-links.

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

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

Attached to or formed with the inner sides of the hubs of both carrying-wheels are pinions P, which continually revolve with the carrying-wheels; and suitably fastened to or formed integral with the side arms, J, on their outer sides directly over the pinions P, and concentric with the rocking axis of the rake-head, 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 rock-shaft K, are bell-crank arms R, to the lower rear ends of which are journaled the intermediate pinions, S, which mesh with the segment-pinions Q at all times, but only with the pinions P when it is desired to dump the rake by its own traction.

Just outside of the arms R, and keyed or otherwise rigidly secured to the projecting ends of the rock-shaft K, are the downwardly and forwardly inclined arms T, which, by means of set-screws a, bear against and support the forward ends of the arms R to hold their rear ends elevated, as seen in Figs. 1 and 2, for the purpose of sustaining the intermediate pinions, S, out of engagement with the pinions P. I have shown the set-screws as inserted through the arms T and bearing against the arms R, but it is evident that the set-screws-might be inserted through the arms R and bear against the arms T. These setscrews are desirable for purposes of adjustment to insure the coincident engagement of the pinions S and P on both sides of the rake, as will be readily understood, though they might be dispensed with and the arms T and It be made to engage directly.

As a means for oscillating the shaft K to allow the pinions S and P to come into mesh, I employ the pendent arm 12, which, rigidly fastened to the rock-shaft K at or near the middle of the rake, extends down in front of 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 I) is passed the front end of a bolt, 0, which extends back through the axle, which is counterbored from its rear side 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 the spring may be adjusted'bynuts 6 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), and consequently the shaft K, in such position that the arms T will hold up the arms R, and thereby keep the intermediate pinions disengaged from the pinions P, as shown particularly in Figs. 1 and 2, and also to retract the rock-shaft K and raise the pinions S when thelock has been broken.

Projecting through a slot in the arm b is a latch, f, which is pivoted to the axle, as shown, has near its forward end a locking-notch on its under side, and is forced down by any suitable spring, g, interposed between itand the axle; The end or nose of the latch is rounded or beveled, as shown, and suitably located upon the rocking frame is a projection or arm, h, carrying a small friction-roller, 2', adapted to come in contact with the nose of' the latch and lift the same when the teeth have reached the desired point of elevation, and to aid, if need be, in forcing back the arm b, and, by oscillating the rock-shaft K, raising the arms R to disengage the pinions S and P.

From this construction it will be readily understood that when the driver wishes to dump the rake he merely has to press his foot upon the chain, thereby drawing forward the arm (2 until the notch in the latch f engages with and holds it locked. This drawing forward the arm I) oscillates the shaft K, which as it turns raises the arms T and permits the arms P to drop and bring the pinions S and Pinto engagement, whereupon the revolutions of the pinions P are imparted through the pinions S to the segment-racks Q, and the rakehead is tilted and the teeth thereby elevated. This tilting of the rocking frame or rake-head continues until the rolleri or other suitable strike comes in contact with and lifts the latch f, thereby freeing the arm I), which through the retraction of the spring d is drawn back, and the pinions S are lifted out of engagement with the pinions P to release the rake-head. In case the spring 01 should prove insufficient to turn back the rock-shaft K and effect the disengagement of the-pinions S and P, the roller z would at this moment come in contact with the arm I), and, forcing it back, would thus exert the tilting force of the rake-head directly upon the rock-shaft K to cause the. lifting of the pinions S,- but should the spring d, together with the pressure of the roller 6 upon the arm b prove insufficient to turn back the rock-shaft K and effect the disengagement of the intermediate pinions, I provide lugs or pins j upon the arms J, which would come in contact with the forward extensions of the arms R just after the .roller 2 has released the latch f and has acted upon the arm I), so that any further forward tilting of the rocking frame would be thrown directly upon the forward extension of the arms R and cause them instantly to be thrown up in the ICO Its

rear to release the intermediate pinions and break the lock between the carrying-wheels and rake-head.

It will be seen from this construction, and from the fact that the arms R are loosely pivoted, that, should the rake be in the act of turningin either direction, the self-dumping would take place just the same from that wheel traveling forward, while the intermediate pinion, S, neXt to the other wheel, would merely be thrown back like a pawl escaping from a ratchet without becoming locked, as will be readily understood.

Matters shown and described herein but not claimed are included in my applications No. 114,518, filed December 14, 1888, and No. 114,519, filed December 14, 1883.

Having thus fully described my invention, 1 claim 1. I11 a horse hay-rake, the combination, with the rake-teeth, the rake-head, and carrying-wheels, of an oscillating non-rotating locking-shaft upon which the teeth and rakehead are coincidently journaled, and connecting mechanism whereby said shaft can be oscillated to effect a lock between the rake head and carrying-wheels at the will of the operator to cause the elevation of the teeth as the machine advances or turns.

2. In a horse hay-rake, the combination, with the rake-teeth, the rake-head having segmental racks or pinions rigidly secured thereto, the carrying-wheels having pinions revolving therewith, intermediate pinions constantly meshing with the segmental racks, and an oscillating non-rotating locking-shaft upon which the rake-teeth and rake-head are coin cidentlyj ournaled, and connecting mechanism, whereby upon oscillating said shaft the intermediate pinions are brought into engagement with the pinions upon the carrying-wheels to the rake-head and cause the elevation of the teeth as the machine advances or turns.

8. In a horse hay-rake, the combination of the rocking rake-head carrying the rake-teeth and having segment racks or pinions rigidly secured thereto, pivoted arms carrying intermediate pinions constantly meshing with the segment racks, pinions revolving with the carrying-wheels, an oscillating non-rotating shaft upon which the rake-teeth and rakehead are coincidently journaled, arms secured to the ends of said shaft for controlling the intermediate pinions, an arm also secured to said shaft for rocking it to permit the pinions to come into engagement, a locking device to hold said shaft in its rocked position, and a project-ion upon the rake-head to unlock said shaft and permit its return to effect the disengagement of the pinions when the rake-teeth have been sufficiently elevated.

4. In a horse hay-rake, the combination of the rocking rake-head having segment-pinions rigidly secured thereto, pinions revolving with the carryingwheels, the rock-shaft K, upon which the rake-teeth and rake-head are coincidentlyjournaled and provided with arms T and Z), and the arms R, carrying intermediate pinions, S, substantially as and for the purpose described.

5. The combinatiomwith the rock-shaft K, provided with arms '1, 0f the loosely-hung pinion-carrying arms R, and set-screws a, for effecting the adjustment of the arms R, substantially in the manner and for the purpose specified.
