SPECIFICATION forming part of Letters Patent No. 783,636, dated. February 28, 1905.

Application filed June 1904. Serial No. 210,685.

To (LZZ whom, f/l; may concern:

Be it known that I, DAVI I) S. H ARROLD, a citizen of the United States, residing at Cleveland, in, the county of Stutsman, State of North Dakota, have invented certain new and useful Improvements in Hay-Rakes, of which the following is a specification.

The objects of my invention are to provide a hay-rake of simple, durable, and inexpensive construction designed to be advanced over a Held by draft-animals and to deposit hay in a row at the center of' the machine-frame.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a top or plan view of the complete machine with the pivoted rake-sections in their position at right angles to a foreand-aft line through the machine. The dotted lines indicate the position of one of the pivoted rake-sections in its position parallel with a fore-and-aft line through the machine. Fig. 2 shows a detail side View of one of the traction-wheels. Fig. 3 shows a detail front view of one of the stationary rake-sections in position at right angles to a foreand-aft line through the machin c. Fig. 4- shows a side elevation of the complete machine. Fig. 5 shows a longitudinal sectional view of the machine on the line 5 5 of Fig. '1. Fig. 6shows aside elevation of the machine with the pivoted rakesections in position parallel with a fore-andaft line through the machine. Fig. 7 shows a top or plan view of one of the rigid rakesections and one of the pivoted ral e-sections adjacent thereto. Fig. 8 shows a transverse sectional view on the line 8 8 of Fig. 7. Fig. 9 shows a transverse sectional view through the stationary arm on the line 9 g of Fig. 7.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the body portion of the machine-frame. 1n

the said machine-frame is a rotatable axle 11, upon which the traction-wheels 12 are rotatably mounted. Adjacent to each traction-wheel 12 is a ratchet-wheel 13, fixed to the axle 11, en-

gaged by spring-actuated pawl M, mounted on the traction-wheel. In this way the axle 11 is rotated when either traction-wheel is advanced; but the axle is not rotated when either traction-wheel is moved rearwardly.

The numeral 1 L indicates a beam extending forwardly from the body of the machine frame, and 15 indicates an extension of same, provided with a caster-wheel 16*, to which a tongue is pivoted to swing in a vertical plane.

I have provided means for raising and lowering the forward end of the beam lat relative to the extension 15, as follows: The numeral 16 indicates a bell-crank lever 'fulcrumed at 17 to the extension 15 and having its rear end pivoted at 18 to the beam 14 and having its other end projecting straight downward. A rod 19 is pivoted to the downwardly-projecting end of the bell-crank lever 16 and is extended rearwardly and pivoted at 20 to the lower end of a lever 21, which is fulcrumed to machine-frame at 22 and is provided with a pawl 23, designed to engage a sector at, fixed to the machine-frame. By manipulating the lever 21 the forward end of the beam 14: may be raised and lowered.

At the front of the body portion of the machine-frame are two lixed rake-sections extending at right angles to a fore-and-a'ft line througl'i the machine, with a space between them to permit the hay gathered by the lixed ral e-sections to pass between the said sec tions. Each of the lixed rake-sections comprises the body portion 25, having at its front edge an arm 26, spaced apart from the body portion 25. The rake-teeth are made of metal bars, the upper ends of which are lixed at 27 to the part and the central portions of which are projected through an arm 26. then downward at 28. and the lower ends are extended forwardly at 29. l.\ [ounted above the inner end of each fixed rakesection is a bracket 30, to which the arm 31 is pivoted. This arm 3.1 is provided with a rod 32 atits top, and a munber of spring rake-teeth 33 are connected to the arm 31 by being wound upon the rod 32, with one end 34 secured to the arm 31, as shown in Fig. 8. The said ratchetteeth are then inclined forwardly and downwardly and are passed through the limitingguides 35, secured to the front of the arm 31. In this way the said teeth 33 are normally held by the resiliency of the metal of which they are formed in position against the front of the arm 31, and their outer movement relative to the arm 31 is limited by the guides 35. The outer one of the teeth 33 is arranged to pass beyond the outer end of the body portion of the fixed rake-section, as shown in Fig. 7. i

I have provided means for automatically operating the pivoted rake-sections upon the advance of the machine, as follows: The numeral 36 indicates a shaft pivoted to the machine-frame in front of the axle 11, and fixed thereto is a mutilated gear-wheel 37 and two drums 38. Wound upon each drum 38 is a cable 39, projecting forwardly through the guides 40 and then outwardly around a direct pulley 41 with its outer end fixed to the bracket 42 at the front of the arm 31. Fixed to the axle 11 is a mutilated gear-wheel 43, designed to mesh with the gearwheel 37. This gearwheel 43 is provided with a pin 44, which pin is arranged to engage a slotted arm 45, which arm receives the gear-wheel 43 and is fixed to a rock-shaft 46 in the rear of the axle 11. In this way during each revolution of the gearwheel 43 the arm 45 is engaged by the pin 44 and elevated and held in its elevated position until the pin 44 passes beyond its end, whereupon it is free to drop.

I have provided means for causing the pivoted rake-arms to return to their position at right angles to a fore-and-aft line, as follows: On the ends of the rock-shaft 46 l have fixed arms 47, and to each of said arms I have attached a contractable coil-spring 48, and a cable 49 is attached to the spring and to an eye 50 at the rear of the arm 31.

In practical use and assuming that the machine is being advanced over the field containing cut hay both of the fixed rake-sections will collect the hay lying in their path. The pivoted rake-sections when at their rearward limit of movement have their teeth yieldingly held against the arm 26 of the fixed rake-sections, and when'the pivoted rake-sections begin to moveforward the teeth 33 will be yieldingly held against the front of the arm 26, so that the lower ends of the teeth 33 will move downwardly and engage the hay carried by the fixed rake-sections. Then as the fixed rakesections move forwardly they will carry the accumulated hay to position between the fixed rake-sections, so that as the machine is advanced the hay will be deposited in a rowat the center of the machine. The said hinged rake-sections are slowly moved to their inward limit as the machine is advanced, and when this limit is reached they are quickly moved to their rearward limit by the springs 48. This operation is produced as follows: The springs '48 normally hold the hinged rake-sections at their outer limit of movement, and they also hold the arms 45 at their downward limit. -When the machine is advanced, the mutilated gear 43 is rotated, and it turns the mutilated gear 37. hen the gear 37 is turned, the drums 38 are moved in a direction to wind up the cable 39, and thus slowly draw the hinged rake-sections forwardly and inwardly. Before the hinged rake-sections reach their inward limit of movement the pin 44 has engaged the arm 45 and elevated it, thus applying considerable tension to the spring 48. hen the inner limit of movement of the hinged rake-section is reached, that part of the mutilated gear 43 having no teeth is moved to position adjacent to the mutilated gear 37. Hence the latter gear-wheel is free to rotate, and the springs 48 will then operate to quickly swing the hinged rake-sections to their outer limit. Then as the mutilated gear progresses farther the pin 44 passes beyond the arm 45, and the said arm drops, thus relieving the tension on the spring 48. The position of the rake-teeth relative to the ground-surface may be varied by a manipulation of the lever 21.
