IMPROVEMENT IN HORSE HAY-RAKES.

Specification forming part of Letters Patent No. 166,1 1S, dated July 27, 187.5; application filed January 22, 1875.

To all whom it may concern Be it known that we, CHARLES M. LUEKIN and CHARLES G. ALLEN, ofthe town ofBarre, county of Worcester and State oi' Massachusetts, have invented new and useful Improvehaving apawl engaging with the same, which is.

secured to the axle, such pawl being operated by means of a rod running parallel with and secured to such axle, and operated by means oftreadl'es, levers, and springs, and the action of the same controlled by the feet of the driver while upon his seat, or by the hand ofthe driver by prolonging the arms of such levers, 8vo., in the manner hereinafter described and pointed out in the claims, the construction, operation, and combined action of such pawl, ratchet,

levers, and treadles being intended to accomplish the result of discharging, at the proper time, the hay or other analogous material con4 tained within and by the teeth of the rake. Also in the-construction and arrangement of ,the hay stripper-bar, and its connection with the outer teeth at each end of the rake, and the stripper rods or arms also connected to such stripper-bar, and to a cross-bar, to the latter of which the shafts are attached, as well as to the axle.

In order to enable others skilled in the art to make and use this invention, we will describe the construction and operation of the same.`

In the drawings, Figure l is a top or plan view of the machine. Figs. 2 and 3 are side views in cross-section, showing the position of the rake in two positions, with the arrangement of levers, treadles., and strippers. Fig. 4 shows the position of the pawl, engaged with ratchet, with the projections or lugs formed upon such pawl, and their relation to the vent-arms upon the longitudinal rod in cross-section. Fig. 5 shows a top and plan view of same. Fig. 6 showsv the shield surrounding the ratchet and the pawl, with 7c engage.

the projections on the pawl, which is attached to the larger shield.

In the drawings, A represents the axle, as well as the rakevhead, to which the teeth a a a are secured, such teeth being bent in the form of a halfecircle, or nearly so. B is a crossbar, to which are attached, at right angles, the hayvstrippers a a and a a". of the hay-rake h are pivoted to the axle or head A by means of the bent arms L", and by means of such arms connect the lcross-bar B and axle A together, 4as seen in Fig. 3. The teeth, secured to the axle, can be raised or lowered by turning the axle or pressing the same downward by means of the arm or footpiece e at the left of the drivers seat, who can operate the same and control the movement ot' said teeth, when desired, by raising such teeth when passing over stubble or uneven surfaces, or other obstacles. This device just described is arranged to co-operate with the lever g, rod g', and arm g", the latter se-y cured to the axle A. By pressing down with the foot-lever g, the teeth are held in contact with the hay upon the ground, and the motion of the teeth over uneven ground or obstacles controlled in a similar manner as when they are operated by the arm or footpiece e. The stripper-bar C is secured inposition on the under side of the teeth, by being connected to the end teeth by means of a staple or clevis, t', said end teeth passing through eyes (formed within such staple or clevis) upon the upper side of such stripper-bar C. The two outer stripper-rods a", in addition to being secured to the cross-bar B are also secured to the stripper-bar by means of the. connectingrods a, so that whenthe teeth are raised, or are being raised, the rods a. a and a" a force the hay from the teeth, and are in the position seen in Fig. 3, partly in dotted lines. Another mechanism is also used to perform this operation of releasing the hay from the teeth by means of the motion of the wheels. To the inner portion of the hubs of such wheels are secured ratchets m, with which the pawls The latter are pivoted to the larger shield n, and are raised out of or forced into contact with the ratchets by means f the bent arms upon'the' end of the rod b.` While the rake is in motion the pawls lc rest upon The shafts the said bent arms and disconnected from the ratchets m, the lugs 1 formed upon such pawls then being upon the ends of the bent arms oi' the rod b. A cani shaped projection, 2, is also formed. upon said pawl. so that When the arm or support is removed from the lug 1 the arm presses upon and vdownward the cam 2, forcing the pawl in contact with the ratchet m. The connection of the shield n, to which the pawls areL attached, to the axle causes such axle to rotate, thereby raising the teeth ofthe rake, when the paWls and rachets are in contact with each other. To control the operation of the rod b I employ the foottreadle or lever f, rod f, and arm f the latter securely fastened to the rod b, and Within the control ofthe driver upon his seat p. A spring, d, connects with the rod b and arm f which, upon removal of the foot of the vdriver from the lever f, causes the arms on the end ofthe rod b to resume their support of the lpawl, as before mentioned. To aid in the return ofthe rake to its proper position after the hay is released, I attach a spring, c, to a rod that secures the right-hand shaft to the axle A, so that When the axle is turned downward the spring is Wound up by means of its c011- nection with the axle and rod, and upon the 'withdrawal of the foot from the lever g the spring o causes the axle to return toits normal position. The levers f and g are secured to the foot-board h, and the seat p, and brace la also secured to the foot-board la', as seen in Figs. 1 and 2. The stripper-bar C slides freely upon the end teeth of the rake, and acting also as a support to the teeth aa a., as well as aiding inthe discharge of the hay from the rake.

What We claim as our invention, and desire to secure by LettersPatent, is

- 1. The combination of the leverf, rod fwith the rod b,' and pawl 7c with its lugs 1 and 2, and ratchet m, when constructed and arranged to operate in the manner and for the purpose herein described. 4

2. The stripper-bar C, in combination with the end teeth a a, stripper-rods a, and connecting-rods a", in the manner and for the purpose herein described.

3. The combination of the stripper-rods a" with the connecting-rod a!" and stripper-bar C., and cross-bar B, in the manner and for the purpose herein set forth.

In testimony whereof we have signed our names in the presence of two subscribing witnesses.
