IMPROVEMENT IN HORSE HAY-RAKES.

Specification forming part of "Letters Patent No; 160,993, dated March 23, 1875 reissue No. 7,179, dated June 20, 1876; application tiled May 20, 1876.

To all whom it may concern:

Be it known that I, WILLIAM S. ARCHER, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Horse -Hay-Rakes; and I do hereby declare that the following is a full, clear, and exact description thereof, that Will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to'the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view of the horse hayrake, showing the several improvements. Fig. 2 is part of the rake-head, to which the forkteeth are to be attached. Fig. 3 is a front view of the adjusting-plates by which the elevation of the fork is regulated. Fig. 4 is a sectional elevation of part of Fig. 1, on the line a: as, showing the method of pivoting and operating the hand-lever and the treadle. Fig. 5 is a sectional elevation of Fig. 1, on line y y, showing the hinge by which the horse-shafts are connected to the rake-head. Fig. 6 represents a cross-section and a plan view of the plate-clips which retain the teeth upon the rake-head, and the guard-plate over the teeth to stop the hay. Fig. 7 represents two views of the flanged plate for the support of the wheel-spindle at any point which may be required by the adjustment, as shown in Fig. 3, of the two plates.

The nature of this invention relates to several improvements in horse hay-rakes, whereby they can be more economically constructed, and their operation be more readily controlled, and also in simplifying the devices, and thus rendering the whole apparatus less liable to derangement of parts, as will hereinafter be more fully described.

In the drawing, A A represent the teeth. B is the rake-head, to which the teeth are attached by plates L, in sets of two or more. C O are wheel-spindles in the rear of the rake-head, and fastened adjustably thereto by plates, to be described hereafter. D is a footlever, hinged at one end under the shaft, and to which is fastened a chain, d", leading over a pulley, d, and under the pin 0, and another pulley, f, and affixed to a catch, a, on the lever F. E E are the horse-shafts, which are hinged to the rake-head B at B, and permanently fastened to the beams E at the rear, and E in front, which act as braces, and ,form the frame of the rake. F is a hand-1e ver of peculiar structure and action, having no fixed fulcrum,'but bearing upon a fulcrumpin, 0, alongthe groove 0, thus, while in mo- .tion, lessening the power of the long arm F ;by increasing the distance between the fulcrum-pivot c and the other end of the lever at d, where the weight of the load in the teeth will increase the motion of discharge, as the rake-head turns in the direction of the arrow in Figs. 4 and 5, by the resistance of the load against the teeth, they acting as levers to turn upwardly and permit the load to drop out. The pin b in the lower slot 61' of the lever acts as a guide, and is never reached by the upper end of the slot, therefore cannot act as afulcrum. G H are plates, pivoted together at h, and secured in position relative to each other laterally by a screw-bolt at h, where there are represented three holes but any number desired may be used. The flangeplate g has screw-holes, by which the plate G is secured permanently to the axle or turning beam. In the plate H there is a projecting pipe, it, through which the wheel spindle passes to receive the Wheel, the other end of the spindle being secured in a flanged plate, I, by a groove, 3, formed in a segment of a circle, '5, so that when the plate H, carrying the spindle in the pipe h, is moved to either of the positions at h, the other end of the spindle at 0 can be moved to its parallel position with the axle B, and secured there by the nut-andscrew fastening c. This movement of plates G'r-and H is to adjust the teeth to a higher or lower position, to suit the ground or character of the work to be performed. J is a plate secured to rake-head B, having a tongue, j, to which is pivoted a double link, j, the upper end of which is pivoted to the'end d of lever F. This link j permits the free movement of the rake-head B, when the load causes it to rotate in direction of the arrow to be disresumes its proper position.

charged K is the hooked end of the teeth A A, which laps over the rake-head B, and is held in position loosely by the clip or plate L, which is constructed with two shanks, L L, having within them grooves to cover the teeth,

and a cross-bar,- 1, which is fastened to the rake-head B by a screw at I, so that by this arrangement two teeth can be secured by one the bolts 11 c and pulley d are so arranged that the upper end of the slot 61' shall never bear upon the pin 1) to form a fulcrum.

The construction and operation of the rake are as follows: The teeth A A are attached to the rake-head B, whichcan be turned to raise them and discharge the load either by its weight or by the lever I The rake-head B is hung to and in front of the spindles O O,upon which the wheels revolve. The teeth AAare held in position for raking by the pressure of the drivers foot upon the treadle-lever D, and the load, when accumulated, discharges itself upon releasing the foot from the treadle,which discharge may be assisted by the hand-lever E, if found necessary from any unusual cause. This automatic discharge of the load is due to. the manner of hanging the rake-head B to the shafts E, and in such relation to the wheelspindles G O that sufficient leverage is ob: t ained, by the action of the load'on the teeth,

to easily turn the rake-head, thereby causing the teeth to be raised and. discharge the load. This is effected by placing the center of revolution so far back on the, shafts as, to throw the weight of the rake-head and the plates attached thereto proportionately beyond that center, so asto act, in some, measure, as: an auxiliary weight to the load and its resistance along the ground in dragging, so that, all of that weight on the rake-head helps the revolvin g tendency when the foot-lever is released; So soon as the load shall have been discharged g the pressure of thefoot on the treadledraws the leverF down again, and the rake-head B The driver can reset the teeth by the foot-lever alone, andthe teeth are retained in their raking position by the pressure of thefoot acting upon the, chain, which, being fastened to the lever F at a, and passing under the pin 0, gives a powerfulcontrol of the lever when down, because the distanceof the fulcrum-pin 0' from the. end of the lever at d is the shortest possible when the teeth are gathering the load, which, in the present case, made upon the proper proportions suited to practical results, gives the long arm to the short'as fourteen to one. So soon, however, as the load is ready for discharging, the lever 1) being released, the revolution of rake-head B draws the end 01 of lever F downward and forward, constantly diminishing the proportion from fourteen to one to the maximum of ten to five, which gives arapidly-increasing motion in discharging theload. These are. the proportions in the present case, but any other may be used.

The foot-lever is swung at one end to the shafts but any other means may be employed to draw the chain tight by the application of the foot.

The hand-lever can be used alone to hold the rake-teeth, or for lowering and raising them.

The teeth-fastening is an improvement upon my former patent, granted April 11, 1874.

The teeth pass over the rake-head B, and are bent down to the front thereof, and are held loosely in grooves in the clip or plate L, which plate, having two grooved shanks,

holds'two teeth, and by the perforated connecting-barl is held down by one screw in hole Z, thus afl'ording a ready means of fasteningor releasing the teeth when necessary. The spring of the teeth is accomplished by the two points of bearing- -v iz., at K and k.

A perforated plate, P, is employed to prevent the hay from passing upon the back of the teeth, as seen in Fig. 6. This plate P has a shank, p, by which it is fastened to the.

axle by thesame bolt which secures the clip L, and covers the teeth in pairs, whereby it 'is made to act as a support for two rake-teeth against side pressure, as well as to prevent the clogging of the hay around the upper ends of thetceth.

In this construction of a horse hay-rake there is no gearing, clutches, or ratchets in the wheels, or any other machinery to effect .the discharge of the load; nor is it necessary able and swinging rakahead, hinged at its rear side to the shafts of themachine, it be-.

ing arranged with reference to the wheelspindles, substantially as shown, whereby the position of the outer ends of the rake-teeth can beregulated with reference to the ground,

and whereby the resistance offered by the material to be gathered is. made to aid in swinging the head to a position below the spindles, for the purpose of facilitating the discharge of the load, substantially as set forth.

2. The slotted curved lever F, in combina- 'tion with .the connecting-links j and j and rake-head B, substantially as and for the purpose described.

3. The slotted plate G and plate H, combined with the spindle O, slotted plate I, and rake-head B, substantially asand for the purpose describcd.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of May, 1876. I

WILLIAM S. ARCHER.
