HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 229,349, dated June 29, 1880.

vApplication filed May 5, 1880.

To all whom it may concern:

Be it known that I, WALTER ADRIANOE, a citizen of the United States, residing at Poughkcepsie, in the county of Duchess, in the State of New York, have invented new and useful Improvementsjn Horse Hay-Rakes, of which the following is a specification.

My invention relates to that class of rakes embodying independent wheel-shafts and lifting mechanism co-operating with the wheelshafts, as described in Letters Patent of the United States granted to me October 2, 1877, No. 195,783, or October 15, 1878, No. 209,004.

My present invention consists in the combination, with the rake head and independent,

wheel-shafts, of a lifting-arm attached to the rake head and mounted loosely on either wheel-shaft, or both of them, ratchet-teeth formed in the eye ofthe lifting-arm,-a springpawl sunken into the wheel-shaftin a suitable manner to engage such teeth, a sliding collar mounted on the wheel-shaft for the purpose of depressing the spring-pawl, thereby holding the latter out of gear, a spring acting on the sliding collar with a tendency to force the same into its operative position, and a rock-shaft carrying a crank which connects with the sliding collar by a suitable rod, for moving back the sliding collar against the action of its spring, so that when the rock-shaft is operated in a suitable manner the rake-head is lifted through the medium of the wheel-shaft.

The rock-shaft carries a pedal for its operation by the foot, and with the same is combined a trip-lever, which is arranged to be brought into the path of the rake-head by the direct action of the pedal, so that in the upward movement of the rake-head it displaces the trip-lever, while the latter acts on the pedal of the rock-shaft to throw the lifting mechanism out of gear automatically.

This invention is illustrated in the accompanying drawings, in which- Figure 1 shows a portion of a rake, partly in plan View and partly in section, embodying my invention. Fig. 2 is a cross-section thereof in the line as 00. Figs. 3 and 4. are detail views of parts. i v

' Similar letters indicate corresponding parts. The letter A designates the rake-head, and

B a portion of the rake-frame, in a suit-able part of which are mounted the independent (No model.)

wheel-shafts. These wheel-shafts and their concomitants being substantially identical, I have deemed it necessary to show only one of them, as at G.

TheletterDdesignates the lifting-arm. This arm is attached to and supports the rake-head A, while it is mounted loosely on the wheelshaft 0, so that it is capable of swinging on such shaft.

On the inner surface of the eye, whereby the lifting-arm D is mouhted on the wheel-shaft O, are formed ratchet-teeth c, with which engages, under certain conditions presently explained, a spring-pawl, f. This pawl f is sunken into the wheel-shaft C, the latter being to that end provided with a suitable recess, and it extends in adirection; away from the lifting-arm D lengthwise of thcshaft, so that theshank of the pawl is next to the liftingarm on the shaft.

The letter G designates the collar for de' pressing the spring-pawl f, the same being mounted on the wheel-shaft C, so as to slide thereon, and being subjected to the action of a spring, H, having a tendency to hold the same close up to the lifting-arm 1). When the sliding collar G is brought to the position last named, which is its normal position, it bears on the shank of the spring-pawl f and holds the same outof engagement with the ratchetteeth a, the result of which is that the wheelshaft is permitted to turn without acting on the lifting-arm D. A

I is the rock-shaft, J the crank on the rockshaft, and K the rod whereby the crank connects with the sliding collar G. The rock-shaft I extends at a right angle to the axis of the whecl-shaft G, and on the forward'end thereof is a pedal, 1, whereby the shaft is adapted to be, operated by the foot. The crank J is a double one, and connects with a sliding collar on both wheel-shafts of the rake. The connecting-rod K is hung on the pin of the crank J, and it acts on the sliding collar G by means of a pin, a, the collar being constructed with a knuckle, 0, against which the pin impinges. The end of the connecting -rod K extends through the knuckle 0 of the sliding collar, and forms a support for the spring H, the latter being a spiral spring and bearing against an end piece of the rake-frame.

When it is desired to lift the rake-head A the driver operates the rock-shaft I, when the sliding collar G is pushed back against the action of its spring H through the medium of the crank J and the connecting-rod K, thereby releasing the spring -pawl f, which latter' then engages the ratchet-teeth 0, so that as the wheel-shaft 0 turns with the wheel the liftingarm D partakes of its motion, thus moving the rake-head to an upper or forward position.

The letterPdesignates the trip-lever, which, together with the pedal 1, constitutes a throwoff mechanism for regulating the upper position of the rake-head. The trip-lever P has its fulcrum on a pin or staple attached to the front timber of the rake-frame, and one arm of such lever projects in a forward direction beneath the pedal Z of the rock-shaft, while the other arm thereof extends rearwardly a sufficient distance to be brought into the path of the rake-head. The rearwardly-projeeting arm of the triplever P is heavier than the forward arm thereof, and hence such rear arm has a tendency to fall, thereby elevating the forward arm and causing the same to bear up against the pedal lot the rock-shaft. 7

When the rock-shaft I is set to act on the lifting mechanism the forward arm of the triplever P is depressed by the action of the pedal l, and the rear arm thereof rises, so as to be broughtintothe path of therake-head. Hence when the rake-head reaches a certain heightit strikes and displaces the trip-lever P, which latter thereupon acts on the pedal l to return the rock-shaft I to its original or normal position, whereby the lifting mechanism is automatically thrown out of gear and the rakehead is permitted to fall.

It should be remarked that the trip-lever P and the pedal for setting the same may be used with lifting mechanism other than that herein described.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a horse hay-rake, the lifting-arm D, attached to and supporting the rake-head, and having an eye which is provided on its inner surface with a series of ratchet-teeth, e, and which loosely embraces the axle of the supporting-wheels, in combination with a springactuated pawl, f, pivoted within a longitudinal recess in the axle, and having its free end extending into the eye of the lifting-arm, for engaging and disengaging the ratchet-teeth therein, and mechanism,substantially as described, for disengaging said pawl from the ratchet-teeth, all essentially as and for the purpose set forth.

2. In combination with the lifting-arm D, having an eye provided with ratchet-teeth e, the pawl f, pivoted within a longitudinal recess in the periphery of the axle, a spring for throwing the free end of such pawl outward into engagement with the said ratchet-teeth, a collar encircling the axle and pawl, and a lever and connecting-rod and spring for actuating said collar to release the pawl, all substantially as shown and described.

3. The combination of the rock-shaft I, arranged at right angles to the axis of the wheelshaft, and provided with a double crank, J, and mechanism, substantially as described, connected with said double crank, for-lifting and releasing the rake-head, with a pedal connected to the rock-shaft and a pivoted tripping-lever having one end projecting beneath the pedal and its other end adapted to be brought into the path of the rake-head by the depression of the pedal, essentially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses. r
