HAY-LOADER.

SPECIFICATION forming part of Letters Patent N 0. 761,710, dated June '7, 1904. Application filed November 28, 1903. Serial No- 183,050. (No model.)

T (Ii/l whom, it may concern:

Be it known that 1, GRANT PLUMMER, a citizen of the United States, residing at Salina, in the county of Saline andState of Kansas, have invented a new and useful Hay-Loader,

' of which the following is a specification.

This invention relates to a novel hay-loader of that type in which a wheeled frame, propelled by draft-animals, equipped with a ver tically-movable fork normally disposed in position to constitute a rake and tiltably mounted upon its support in order to permit the dumping of a load accumulated by the fork in the normal position thereof and subsequently elevated to the top of a stack.

Theobject of the invention is to improve the construction andmounting of the fork and to provide novel means operated bythe ad- Vance of the loader to elevate the-fork;

A further object of the invention is toprovide means whereby the fork-elevating mech anism may be thrown into and out of operation and the fork retained in its elevated position, so. that a load of hay having been accumulated by thevfork and the latter raised the machine may be transported from a winnow to the stack, with the fork held station' 'ary during such movement.

A furtherobject ,ofjthe invention is to so mount the fork that itwill be dumped by the weight of the load when released and will then automatically resume its normal position with relation to the fork-frame.

Subordinate to the recited objects are various others which will appear-during the succeeding description of the illustrated embodi ment of the invention,

In the accompanyingdrawings, Figure 1 is a perspective'view of my hay-loader complete, the fork being inits normal or depressed position in close proximity to the ground to facilitate the accumulation'of a load of hay as the loader is advanced. Fig. 2 is a vertical longitudinal sectional View of the subjectmatter of Fig. 1, the elevated and dumped positions of the fork being indicated in dotted lines. Fig. 3 is a plan View of the loader With a portion of the fork-elevating mechanism broken away in order to more clearly show parts which would otherwise be hidden, and

- the bar 13 and disposed below the teeth.

Fig. 4 is a detail view showing the pawl-andratchet connection between one of the carry- "and connected by transverse frame-bars 2, lo-

cated adjacent to the opposite ends of the frame and at intermediate points. At a point slightly in advance of the rear end of the base is located a vertically-disposed arch 3, stiffened by inclined braces 1, extending from the upper end of the arch to the beams 1 at advanced points. The frame thus constructed is supported by carrying-Wheels 5-and casterwheels 6, located, respectively, at the front and rear ends-of the frame. The carrying- Wheels 5 are mounted upon a transverse driving-shaft 7, journaled in-suitable boxing carried by the frame and having pawl-and-ratchet connection with the carrying-wheels in a manner well understood in the art (see Fig. 1) to compel the rotation of the wheels andshaft when the loader is advanced over the field and to permit independent rotation of wheels when the loader is backed or turned.

- From the upper end of thearch 3 is swung by any suitable character of connection a .ver-- -t1cally-movable fork-frame 8, comprising for-.

wardly-diverging side bars 9 and l0,extended beyond the front end of the frame and carrying a tiltable fork 11. The fork 11 comprises. a series of tapering teeth or tines 12, connected at their rear ends to a cross-bar 13, disposed above the teeth, and also to a second cross-bar 11, located somewhat in advanc(eS of ee Fig. 1.) The rigid retention of the bar 11 is bar 14 and the end-teeth of the series; Pivotal connection'between the fork and forkframe is preferably effected by means of bearing-brackets 16, attached to the bar 14. and having pivotalconnection-with the front extremities of the side bars 9 and 10 of the fork-frame. This particular charater of connection, however, is not essential and may insured by braces 15, extending between the be substituted by any other possessing the necessary durability.

At the rear side of the fork 11 the latter is provided with a vertically-disposed guard 17, comprising a series of teeth 18, connected by a guard-bar 19, which latter is normally engaged by a locking device in the form of a catch 20, pivotally mounted at its lower end upon a transverse bar 21, connecting the side bars 9 and 10 of the fork-frame at a point in rear of the fork. (See Fig. 2.) Normally the rear bar 13 of the fork rests upon the fork-frame, as shown in Fig. 2, and is rigidly retained in such position by the catch 20, the latter being yieldingly retained in its engaging position by a spring 22, preferably secured to the catch and having a free end disposed to bear against the rear side of the bar 21. hen

the fork-frame is swung up to the position indicated in dotted lines in Fig. 2 for the purpose of elevating the load accumulated upon fork, the catch is drawn back in opposition to the spring 22 by means of a cable 23, secured to the catch, and extended back to the drivers seat 24, supported at the rear extremity of the loader-frame. When the catch is thus withdrawn from the fork, the weight of the load of hay accumulated thereon will tilt the fork to the inclined position, (indicated in Fig. 2,) the tilting movement of the fork being limited by any suitable means as, for instance, a chain 25, secured to the

bars

13 and 21, respectively. As soon as the load of hay is discharged from the fork the latter will tilt back to its normal position upon the forkframe by reason of the fact that the rear end of the fork structure is sufficiently heavy to compel this movement.

The fork-elevating mechanism, which embraces the means whereby the fork-frame is raised from the position shown in Fig. 1 to that indicated in dotted lines in Fig. 2, comprises a swinging arch or fulcrum support 26, composed of side bars 27 and connecting-braces 28. This arch or support is pivotally connected at its lower end to one of the transverse bars 2 of the frame-baseas, for instance, by means of bearing-brackets 29, secured to said bar 2 and having pivotal connection with the lower ends of the bar 27 Between the upper extremities of the bars 27 is extended a transverse shaft 30, constituting the fulcrum of a fork-elevating lever 31. The lever 31 is in the form of a trussed frame including side bars 32, equipped intermediate of their ends with bearing-brack ets 33, mounted upon the shaft 30 adjacent to its opposite ends, but preferably opposed to the inner sides of the side bars 27 of the swinging fulcrum-support, which latter thus constitutes means for preventing undue lateral vibration of the lever. The side bars 32, which diverge toward their front ends have terminal pivotal connections with the transverse bar 21 of the fork-frame by means of suitable bearing-brackets, so that when the lever is swung by power applied to the rear end thereof the fork-frame will be swung up for the purpose of elevating a load of hay accumulated upon the fork. As has been premised, this application of power to the fork-raising lever is effected by the advance of the loader.

Upon the shaft 7 at a point within the confines of the frame is loosely mounted a drum 34, upon which is wound one end of a forkelevating cable 35, passed around a pulley 36, secured to one of the bars 2 adjacent to the rear end of the frame. The opposite end of the cable is attached to the rear end of the lever 31 and when wound upon the drum in a manner to be described causes the lever to swing and the fork to be elevated by the upward movement of the fork-frame. On one end of the drum 34 is formed a clutch-face 37, designed to be engaged by a clutch-collar 33, splined upon the shaft 7 and urged toward the drum by a spring 39. The collar 38 is designed to be withdrawn from engagement with the drum by means of a bell crank clutch member 40, mounted on one of the transverse bars 2 of the frame-base and connected to a rod 42, extending to a hand-lever 43, arranged immediately in advance of the drivers seat and provided, as usual, with a spring-latch engaging a toothed segn'ient 44 to retain the lever in its adjusted positions. When the loader is advanced, the carryingwheels rotate the shaft 7 and the clutch-collar 38, the latter serving to rotate the drum and to wind the cable 35 thereon.

It will be obvious that after the fork is loaded and elevated it may be desired to transport the leader a considerable distance to the stack, and as the clutch-collar33 will be withdrawn from the drum during such movement means must be provided for preventing the reverse rotation of the drum, so that the latter will not be prematurely lowered by the unwinding of the cable. The present embodiment of such means comprises a brakeband 45, passed around one end of the drum 34 and having one extremity secured to the adjacent frame-bar 2. The free end of the brake-band 45 is attached to a brake-rod 46, connected to a brake-lever 47 similar to the lever 43 and likewise having a spring-catch engaging the segmental rack 44. \Vhen the fork has been raised, the brake-lever 47 may be manipulated to apply the brake to the drum, and the machine may be transported to the stack after first withdrawing the clutchcollar 38 from engagement with the drum.

Any suitable means for attaching the draftanimals to the loader may be provided; but by preference a draft-bar 48 is bolted to the frame-base immediately in rear of the arch 3 and is provided at its opposite ends with swingletrees 49. The usual hold-back chains 50 are connected to the side bars 1 of the. framc-base at the proper points, and these bars are also provided with loops 51 for the attachment of the head-straps.

Briefly, theoperation of the loader is as follows: The device, organized as shown in Fig. 1 of the drawings, is drawn over the field, and the fork acting as a bull-rake accumulates the load of hay. The clutch lever 43 is then manipulated to permit the engagement of the drum by the clutch collar 38, and a farther advance of the machine will thus effect the rotation of the drum, such motion being communicated thereto from the carrying-wheels. As the drum rotates,the cable 35 will be wound thereon, drawing down the rear end of the lever 31. The swinging of said lever will necessarily be accompanied by the swinging of the fork-frame from the rear arch, and as thelever is connected to said frame it follows that as the latter moves. up the fulcrum of the lever will shift. It is to accommodate this shifting movement of the fulcrum that the swinging support 26 is provided.v As the ver 37 is manipulated to apply the brake, the

lever 43 is manipulated to disconnect the drum from the shaft, and the loader is advanced toward the stack. When the stack is reached, the operator, by apull upon the cable 35, withdraws the catch from the guard-bar 19 of the fork, the latter is tilted forward under the weight of the hay, and as soon as the latter is discharged upon the stack the fork drops back and is reengaged by the catch. The loader is now advanced for a new load, and having arrived at the proper point the brake is released to permit the fork-frame and fork to drop back to their initial positions for a repetition of the described operation.

It is thought that from the foregoing the construction, operation, and many advantages of my improved hay-loader will be clearly apparent; but while the present embodiment of the invention is thought'at this time to be preferable I desire to reserve the right to effeet such changes, modifications, and variations of the illustrated structure as may fall fairly within the scope of the protection prayed.
