HAY-RAKE.

SPECIFICATION forming part, of Letters Patent No. 586,264, dated July 13, 1897. Application filed June 19,1895. Serial No. 553,377. (No model.)

1" 0 coZZ whom it may concern:

Be it known that I, EDGAR A. WVRIGHT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Hay-Rakes, of which the following is a clear and full description, reference being had to the accompanying drawings, in which Figure 1 is a plan View of a hay-rake in which my invention is exemplified. Fig. 2 is a sectional elevation showing the raketecth and their controlling parts in the normal position, Fig. 3 is a similar view showing the rake-teeth and their controlling parts in the discharging position. Fig. 4 is an enlarged sectional elevation. Fig. 5 is a front View of one end of the rake-head and adjacent carrying-wheel and parts. Figs. 6, 7, 8, 9, 10, 11, and 12 are details of construction. Fig. 13 is a plan view of the convertible pole and shafts when in the position to be used as a pole. Figs. 1i and 15 are side elevations showing a manual discharging apparatus applied to the rake. Fig. 16 is a sectional view of the ratchet-wheel D.

My invention refers to that class of hayrakes which is supported on two carryingwheels and drawn by animal power and in which the rake-head carrying the rake-teeth is adapted to be rocked upon the axles of the said carrying-wheels as axes in order to discharge the load.

The object of my invention is to provide a rake thatis more effective in its operation and more durable and less expensive in construction.

Referring to the drawings, A and A are the usual carrying-wheels.

B is the rake-head, preferably of anglesteel, and to which the rake-teeth are attached. The rake-head terminates at each end in axle-seats B and B suitably secured thereto, preferably, as shown, by bolts. The stub-axles b and b are secured at b and b. As shown in Figs. 5, 6, and 8, the axle-seats are secured to the rake-head by bolts b two of which are further utilized in securing the axle b.

The hubs a of the carrying-wheels are fitted with bushings a, the peculiar feature of which is the means by which the ratchetwheels D are secured thereto.

Referring to Figs. 11 and 12, will be seen lugs a on the bushing near its inner end. In the ratchet-wheel D, Fig. 12, is an aperture d, having notches cl, corresponding to the lugs or projections a on the bushing.

61 d are inclined surfaces upon the face of the wheel D. To secure the said ratchet- Wheels to the said bushings, they are slipped thereon from the inner end past the lugs a and then given a peripheral motion in a direction opposite the direction of wheel travel until they tighten by means of the inclines d binding between lugs a and the flanges a Axle-seats B and B are provided with shields and supports for an automatic discharging attachment, as shown in Figs. 5 and 6. In Fig. 8 is shown a similar axle-seat B adapted to be secured by the same bolts to the rake-head B, to be used when a manual discharge device is used and which does not have a shield for the ratchet-wheel or a support for the trip-rod, which is unnecessary in a hand dump-rake.

lVhen rakehead B, carrying the teeth C, is rocked to discharge the load, it rocks upon the stud-axles h and b in the supportingwheels, when used either as an automatic or a hand dump-rake. When used as an automatic dump-machine, the head is thrown into engagement with the wheels in order that it may be rocked to discharge by the mechanism which will now be described. The triprod F is rotatably supported in the castings B and B at f and f and its ends F and F are made pawl-shaped, so as to suitably engage the teeth of the ratchet-wheels D. The trip-rod is controlled by a cam G, which is pivoted upon the bracket g, suitably secured to the hound-frame. The cam-lever extends rearwardly from its pivot, which extension has formed therein a curved slot 9', and extends forwardly, terminating in a foot-pad The rod F is bent in the form of a crank at the point f which crank is situated so as to engage the can1-s'lot-g and radiate from the rod F relatively to the pawls F and F so that the Weight of the said lever G acts to hold the pawls at the ends of the rod normally out of engagement with the ratchetwheels D. The pawls are thrown into engagement with the ratchet-wheels by the operator pressing with his foot upon the pedal 9 of the lever g, as will be seen by referring to Fig. 9, in which the full lines indicate the tripped position and the dotted lines the normal position of the cam-lever and triprod. lVhen tripped as above described, the rake-head is rocked upon the stub-axles as centers by means of the ratchet-wheels and the trip-rod supported and carried in the axle-seats B and 13 until the parts reach the discharging position, (shown in Fig. 3,) when the crank f reaches the end of the slot in the cam'lever. A continued stress of parts to rock the rake-head, forcing the pawl's out of engagement with the ratchet-wheels, causes the rake-head to drop back to its initial position.

To hold the rake in its raking position until a sufficient load has been gathered, a footlever H is provided, pivoted in the bracket 7t, and has a footpad h attached at its upperend by means of which the operator appliesstress to hold the rake in the raking position. A bracket 72?, suitably secured to the rake-head, serves a double purpose, one to sustain the trip-rod in about the center of its length and another to afford a pivot to which the connecting-rod H is attached, which connectingrod connects the foot-lever to the rake-head. The rear end 71 of the said connecting-rod is slotted in order that the rake-head may have a limited movement, or, in other words, to give a limited floating action to the rake as a whole as it travels over uneven ground. The front end. h is preferably provided with a number of adjustment-holes by which the foot-lever and the connecting-rod can .be coupled together, so that the positions of the points of the teeth are adjustable to suit the different conditions under which rakes are used. It is desirable that a hand-lever I should be provided in order to move the raketeeth to their discharging position when the liable to strike the operator.

machine is stationary. It is pivoted preferably upon an axle coincident with that of the foot-lever H, and so pivoted as to remain stationary when the rake is moved to discharge its load, unless it is itself the means for discharging the load. This is the preferred construction, because if the lever moved every time the rake was discharged it would be This lever is rendered operative in the manner as above described, preferably by placing it alongside of the foot-lever and in front of the foot-pad at the upper end of the said foot-lever, so that when the said hand-lever is pulled rearwardly by the operator it will strike the said foot-pad and carry the foot-lever with it to discharge the load of the rake.

Pivoted conveniently upon the foot-lever is a latch J, having a toe-padj at its upper end and a hook or pawl j at its lower end,

the said hook adapted by the aid of gravity to engage teeth 71 upon the bracket h when the rake is moved to its discharging position. A number of teeth may be provided upon the bracket it, so that the latch may engage any one of them, no matter what adjustments are made in the operative lengths of the connecting-rod, as previously described. The purpose of the latch J is to hold the rake-teeth -in their discharging position when the machine is being drawn over a road or from field to field. The operator takes his foot 01f the cam-lever after tripping the trip-rod into enit on the pad of the latch J, so that the machine will not be latched in its discharging position under ordinary working conditions.

1nal position, the operator removes his foot from the latch and places it on the foot-lever to hold the machine when raking.

The teeth 0 are secured to the rake-head B by clips 0, as shown in Figs. 4 and 5. The teeth project forwardly through slots 0' in the rake-head, are preferably coiled a number of times to provide elasticity, (preferably twice, as shown,) and extended transversely to form an axis 0 the termination of the said axis being bent, as 0 The clip 0 forms with the rake-head a journal-bearing for the axis 0 The bent portion 0 forms a limit to the free play of the rake-tooth in its support, as shown in Fig. 4. It will thus be seen that the rake as a whole has a limited rocking movement in its normal position and also that each rake-tooth has an independent limited said movement is limited by the bent portion 0 striking the side of the rake-head.

In Figs. 1-1 and 15 is shown the manuald israke in place of the automatic discharge device previously described. N is an arm bolted to the rake-head B by the same bolts 72 and n used to secure the arm h (previously described) thereto. Link O'is pivoted to the said arm N and extends forwardly to a point adjacent to the bracket 0, in which the handlever P is pivoted. The link 0 is pivoted to the hand-lever P at p, and its front end 0 rests upon the ledge 0' upon the bracket 0,

' when the teeth are in their raking position.

5 This construction provides a lock for the f lever, as will be clearly understood by reference to Fig. 14.. The bracket 0 is secured to the hound-frame by bolts 0 and 0 which i are also used in securing the bracket h of the self-dump device in the same place. The hound-frame is hinged to the rake-head by hinges secured to both parts by bolts common to both the self and'hand dump devices,

; but the location of the hinge-pivots are preferably difierent in order that the weight of the operator may assist in dumping the rake.

i It will be understood that I do not intend to limit my claims to the particular'forms of gagement with the ratchet-wheels and places movement upon its attachment-clip, and the" charge device, which can be applied to the- \Vhen the parts have returned to their nor- IIO automatic or manual discharging apparatus herein shown and described, because either may be used in connection with my invention when materially modified.

The hound-frame upon which the operators seat is attached and to which the convertible pole and shafts are attached, as will be hereinafter described, is hinged to the rake-head at 7; and L in anyconvenientmanner, and it consists of two pieces, preferably of angle metal, one piece K being bent to form the front sill and the ends 7.: and the other piece K forming the rear sill of the frame.

The parts K and K are preferably secured to each other by means of the hinge-pieces L and 7.9 A draft-bar K is secured to the front and rear sills in the centerof their width and projects forwardly to provide means whereby the thills when converted into a pole are attached to the frame and whereby the whiffletree is pivoted to the said frame when the thills are used as thills.

Referring to Fig. 13, it will be seen that when the thills are placed together to form a tongue they are bolted together and lie between the parts 7t and the draft-iron K The bolt that secures the whiffletree to the draft-iron is utilized to secure the tongue, and the braces m and 'm serve to hold the tongue in place.

The particular means shown in the drawings of attaching the draft-bar to the front sill is a distance-piece k through which rivets are passed'to secure the parts together. This piece extends forwardly in an arm between which and the forward extension of the draftbar the thills or the whifiletree are attached. The draft-bar K is secured to the rear sill K when both are of angle metal, preferably by rivets orbolts passing throughadistancepiece 75, which piece has a rearward extension L which extension affords means for holding the cleaner L in place. The said cleaner maybe considered as any of the wellknown kinds and is shown in the drawings as consisting of the gas-pipe 1, carried upon the bar 70 in brackets Z and Z and rearwardlyprojecting fingers Z secured to the said gas-pipe and held in position by the transverse distance-rod Z*. The cleaner is adapted to rock in the brackets l and Z and one of the fingers Z projects through a slotted hole in the extension 76, whereby a limited movement to the cleaner is permitted.

M and M are the thills or shafts bolted to the ends 7& and 7c of the hound-frame, preferably by bolts on, and braced to the said frame by braces m and 771 To give the thills the correct position, the ends k and k are made to converge forwardly, as shown in Fig. 1. IVhen two horses are used, the thills are converted into a tongue by bolting them to the bar K of the hound-frame, as shown in Fig. 13, and byswinging the braces m and m upon the bolts that secure them to the said frame and bolting the forward ends of to secure by Letters Patent, is-

1. In a rake, a hound-frame, the front side and end of which consists of a single angle- 80 bar so bent that the said end pieces may converge in a forward direction to contract the space between the thills secured thereto at their forward ends to the extent desired, said angle-bar having its vertical member at the inner side of its ends, and the butt-s of said thills secured outside of said vertical member and beneath the horizontal angle, substantially as described.

2. A rake hound-frame adapted to receive thills, said frame constructed of angle-iron and consisting of a rear bar, a front piece and end pieces formed by bending the same, said end pieces secured to said rear bar, the butts of the thills bolted within the angles of the said end pieces, and the latter converging in a forward direction to such an extent as to throw the forward extremity of the thills the proper distance apart, substantially as described.

3. In a rake, convertible thills and tongues and hounds constructed in the following manner: a hound-frame formed of a single piece of angle-iron, having end parts converging relative to each other in a forward direction and adapted to receive the butts of the thills substantially as described, secured to the bar K, and having the intermediate forwardlyprojected bar K secured to the said bent bar and to the bar K adapted to receive the butts I I0 of the thills when placed side by side to form a tongue for the purpose set forth.

4c. In a rake, convertible thills and tongue constructed in the following manner: a hound-frame having end parts converging relative to each other in a forward direction and adapted to receive the butts of the thills, substantially as described, and having the intermediate bar and forwardly-projecting bar K adapted also to receive the butts of the [20 thills when placed side by side to form a tongue, the said bars to which the thills are secured when formed into a draft-tongue deflected downwardly relative to the plane of the sides of the hound-frame to which they 12 5 are secured when used as thills, whereby the. tongue so formed is lower at the front end than the parts forming it are when used as thills, substantially as described.

5. In a rake, the combination of the rake- 1 0 head of angle metal, with a series of teeth projecting through slots in the vertical pornals assume relative to the head determining the amount of free movement of the said teeth in their supports, substantially as described EDGAR A. YVRIGHT.
