Specification of Letters Patent.

Application lefi April 29,1905. Serial No. 258,098.

To @ZZ whom it may concern.-

Beit known that I, WILSON W. MILLER, a citizen of the United States, residing at Newton, in the county of Harvey and State of Kansas, have invented a new and useful Push-Rake, of which the following is a speci- Iication.

This 'invention relates to improvements in that type of rake wherein a forwardly-projecting fork is employed on which the hay or other material is collected and is ordinarily transported to astacker.

One of the principal objects is to provide a rake of this character with means for ej ecting the load therefrom, and to furthermore provide novel mechanism of a very simple nature for effecting the movement of the ejector, said mechanism being compact and out of the way, easily thrown into and out of operation, of such a nature that it may be readily and cheaply manufactured, and, furthermore, being durable, not liable to derangement, and efficient in operation.

The preferred embodiment of the invention is illustrated in the accompanying drawings, Wherein- Figure 1 is a top plan view of the rake. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation, the fork-tines being shown in section. Fig. 4 is a longitudinal sectional view through the structure. Fig. 5 is a detail plan view of the drum and clutch. Fig. 6 is a cross-sectional view on the line 6 6 of Fig. 4.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a fork 7 1s employed,` comprising forwardly-extending tines or teeth 8, secured at their ends between a pair of transverse holding-bars 9. This fork is provided at its opposite sides with boxes 10, in which is j ournaled an axleshaft 11, to which are rigidly secured groundwheels 12, constituting a support for the rear portion of the fork. A rearwardly-extending tongue 13 has its front end secured to a yolrebracket 14, the terminals of which are pivotally connected to ears 15, secured to the fork over the axle-shaft. A cross-bar 16 1s fastened to the rear end of the tongue, and journaled upon the end portions thereof are caster-wheels 17. To the cross-bar are connected whiflietrees. 18, whereb the draftanimals may be hitched to t e machine.

to, the front end being adapted to move along the surface of the ground, as shown in Fig. 4, or be elevated above the same, as illustrated in Fig. 2. For the purpose of eecting these movements and holding the fork in different positions a lever 22 is employed, which is Vmounted on a rack-plate 23, secured to one side of the tongue 13 just in advance of the usual seat 24. To this lever is connected a link-rod 25, having at its front end an eye 26, that pivotally receives the central portion of a bowed cross-rod 27, the ends of which are fastened to the side portions of the rake; It will thus be seen that the operator by moving the lever in one direction or the other may depress or elevate the front end of the fork and may also secure it in either po- For the purpose of removing the load from the fork an ejector is provided in the' form of an open frame 28, located transversely upon the fork and movable thereover. This frame is provided at its ends with keeper-brackets 29, embracing the side teeth or tines 8 and having rollers 30 operating upon the opposite faces of said teeth or tines. The frame, furthermore, has journaled in its lower bar a series of antifriction-rollers 31, which operate upon the intermediate teeth or tines. The ej ector-frame 23is connected to an actuating-l bar 32, which is slidably mounted directly upon the tongue 13 and is movable longitudinally thereof. Connection is made by means of a rearwardly-projecting bar-section 33, rigidly secured to the ejector-frame at the central portion thereof and having its rear end pivotally connected, as shown at 34, to the front end of the actuating-bar 32.

The end portions of the ejector-frame are braced by links 35, connected, as shown at 36, to the ends of said frame and having their rear ends pivotally connected, as shown at 39, to the actuating-bar 32. The ejector is IOO IIO

urged to upright position by a coiled spring 40, connected to its central upper portion and to the front end of the actuating-bar. In order to reduce the friction between the tongue 13 and actuating-bar 32, aroller 41 is carried by the latter, which operates on the upper face of the former, while another roller 42, carried by a guide-bracket 43, operates against the lower face of the tongue 13.

For the purpose of effecting the operation of the ejector a cable 44 is secured to the rear end of the actuating-bar 32, said end being provided with a depending guide-lug 45, that is movable in a slot 46 in the rear portion of the tongue. The front end of this cable is adapted to be wound upon a drum 47, loosely journaled on the central portion of the axleshaft 11, to which it is adapted to be clutched by means of the clutch members 48, one of which is secured to the drum, the other being lfixed upon the axle-shaft. The drum clutch member 48 is provided with an annular groove 49, in which is engaged the forked arm 50 of a bell-crank lever 51, pivoted upon the tongue 13 and having a link connection 52 with an actuating-lever 53, located just in advance of the seat 24 and on the opposite side of the tongue to the lever 22.

In loading the rake the fork is depressed and the drum unclutched from the axle-shaft. Therefore, as the rake is propelled Jforwardly the hay will collect thereon and move the 'ejector-frame rearwardly. When a load has been collected, the operator elevates the front end of the fork and the load can thus be transported over the field to a stacker or to the place at which such load is to be deposited. To remove the load, the front of the fork is again depressed, the drum is clutched to the axle-shaft, and the rake is backed. Thereupon the cable will be wound upon the drum, thus moving the actuating-bar 32 forwardly with respect to the tongue, and consequently pushing the ejector toward the front end of the fork. As a result it will be seen that the load will be ejected from said fork. As soon as this action has been accomplished, the fork can be againraised, the drum unclutched, and the rake returned to the field for a repetition of the operation described.

It will thus be seen that a simple mechanism is provided for ejecting a load from the fork, that this mechanism is compact and is entirely out of the way, being located wholly in rear of and below the fork. Moreover, the parts are such that there is little liability of derangement and comparatively little friction in operation.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
