HAY-LOADER.

SPECIFICATION forming part of Letters Patent No. 404,096, dated May 28, 1889.

Application filed September 2'7, 1888. Serial No. 286,593. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH LASACK, of Oxford Junction, in the county of Jones and State of Iowa, have invented a new and Improved Hay-Loader, of which the following is a full, clear, and exact description.

My invention relates to an improvement in hay-loaders provided with side rakes and reciprocating elevating-bars; and the object of the invention is to provide a device of simple and effective construction whereby the hay may be effectually gathered from the sides as well as from the rear of the machine and conveyed from said sides to the body, and from thence to a wagon or other vehicle adapted to transport the same.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the loader. Fig. 2 is a plan view of the same centrally broken away. Fig. 3 is a front elevation broken away at the top to illustrate the upper crank movement. Fig. 4 is a longitudinal vertical section on line 0c of Fig. 2. Fig. 5 isa plan View of the boxes journaling the upper crank-shaft. Fig. 6 is a side elevation of the boxes, partly broken away; and Fig. 7 is a tranverse section on line y y of Fig. 6.

In carrying out the invention the drive- Wheels 10 of the hay-loader are secured upon an axle, 11. Upon the said axle 11 the main frame of the implement is supported, which is composed mainly of side bars, 12, crossbars 13, and the verticalstandards 15, attached to the side bars and front cross-bars, as best illustrated in Figs. 1 and 4.

The standards or uprights 15 are provided with a suitable brace, 16, secured, respectively, to the same and to the side bars, 12, and upon the front cross-bar, 13, the tongue 17 is pivoted in the casting 17 provided with hinged braces 18, secured to the tongue and to the staple 18 at the extremities of the said front cross-bar. This main frame is adapted to support the chute or elevator, and consists of the parallel side pieces, 19, upon the upper faces of which a series of transverse bars, 20, are secured, extending from the top to a point approximating the bottom, and upon the said cross-bars 20 a series of longitudinal spaced slats, 21, are attached, which slats constitute the floor of the chute or elevator. Side rails, 22, are provided for the elevator or chute, being attached thereto by suitable standards, 23, as best shown in Fig. 1.

The chute or elevator frame is attached to the main frame, resting at the lower end upon the rear extremities of the said frame and being supported near the upper end by the standard 15, as best shown in Figs. 1 and 4, from which it will be observed that the elevator is given an inclination from the ground upward.

To the rear end of the elevator shoes 24 are attached, which shoes curve in direction of the rear and are adapted to run upon the ground and balance the loader. The rear standards, 23, are carried upward above the side rails, 22, having attached thereto at the upper end a brace, 25, which brace, extending diagonally forward, is secured to the side pieces of the elevator. Upon these uprights or standards or near the rear end of the brace 25 the rake-head 26 is rigidly secured, which rake-head is provided with a series of raketeeth, 27, curved downwardly over the rear end of the loader to a contact with the ground, as illustrated in Figs. 1 and 4.

The rake-teeth consist of spring-wires of suitable diameter, the upper ends of which are rigidly secured in the head. The wire is then carried forward at right angles from the head and is bent upon itself, forming a coil, 28. From thence the wire is carried rearward, passed through the guide-staple 29, and then downward in a gradual curve to the ground, as best shown in Fig. 4.

For elevating the hay in the elevator I provide eight or more elevating-bars, 30. These bars are provided wit-h a series of longitudinally-arranged stop-hinged fingers, 31, and the said elevating-bars are adapted to be alternately reciprocated and moved to and from the bed of the elevator by means of crankshafts 32 and 33, hereinafter described. 7

The fingers 31 of the rake-bars 30 are by preference bent at a right angle and attached to the bars 100 sely bythe staples 34 and pro ards 23, projecting upward from the sides of jected down through slots 35, produced in the said bars, so that the rear ends of the slots lock the fingers against downward movement or permit the said fingers to have an uninterrupted upward movement. In this manner the fingers will ride over the hay upon the downward movement of the bars 30 and engage therewith upon the upward movement of the said bars. This motion will cause the hay to be rapidly and continuously carried up the elevator.

The crank- shafts 32 and 33 are provided with a series of oppositely-bent crank-arms, 36, one crank-arm being provided for each of the elevating-bars 30". The upper crankshaft, 32, is journaled in one pair of the standthe elevator, as best shown in Fig. 3, and the several crank-arms are attached to the several elevating-bars 30 through the medium of a sliding bearing-block,' 40, in a casing, 38.

The bearing-block and its casing is best illustrated in Figs. 5, 6, and 7, and" consists, preferably, of a rectangular casing, 38, provided with a longitudinal slot, 39, which slot, extending through a portion of the top, likewise extends through the sides, as best illus trated in Figs 5 and 6. WVithin the slot 39 the bearing-block 40 is held to reciprocate, which bearing-block is provided in the side with a central aperture, 41, to receive the shaft, and is preferably made in two horizontal sections united in any approved manner. The bearing-block is further provided in the upper face with a small aperture, 42, leading down into the aperture 41,'the aperture 42 being purposed to receive oil to lubricate. This sliding bearing-block greatly facilitates the true revolution of the shaft, inasmuch as I it will not be affected by the vibration or irregular movement of the loader over uneven ground.

The crank-shaft 33 is similarly constructed to the upper crank-shaft, 32, one crank-arm being attached to each of the elevating-bars; but the said lower crank-shaft, 33, is journaled to each of the rake-bars in ordinary fixed bearings, 43. The extremities of the lower crank-shaft are preferably j ournaled in.

boxes 44, attached to the lower standards, 23, as best illustrated in Fig. 1, and upon opposite ends of the two crank-shafts 32 and 33 a sprocket-wheel, 45 and- 46, is respectively secured.

Above the axle 11, and slightly to the rear, a shaft,47, is journaled to and beneath the pieces 19 of the elevator, carrying upon each end, respectively, a sprocket-wheel, 48 and 49, which sprocket-wheels are connected by chain belts 50 and 51 with the sprocket-wheels 45.and 46 of the several crank-shafts, as best illustrated in Fig. 2. The said shaft 47 is also provided at or near the center with a third sprocket-wheel,

' 52. To the rear of the axle 11 the side bars,

12, of the main frame are connected by a crossbar, 53, and from the front of said cross-bar at each side of the center two longitudinal beams, 54 and 55, are projected, in the front ends of which the axle 11 is journaled, the said longitudinal beams 54- and 55 being united near their middle by a transverse beam, 56.

Upon the axle 11 a spur-wheel, 57, is keyed or otherwise secured, which spur-wheel meshes with a pinion, 58, rigidly attached to a short shaft, 59, parallel with the axle, and the shaft 47, journaled in the said longitudinal beams 54 and 55 in front of the connecting-beam 56, as best shown in Fig. 2. At one side of the pinion 58 a sprocket-wheel, 60, is keyed upon the shaft 59, connected by a chain belt, 61, wit-h the sprocket-wheel 52 of the shaft 47. Through the medium of thisconnection motion is transmitted from the drivewheels through the axle 11 to the crank- shafts 32 and 33. A bevel-gear, 62, is also rigidly attached to the short transverse shaft 59, meshing with a bevel-pinion, 63, fast to a longitudinal shaft, 64, journaled, respectively, in the cross-bar 53 and cross-beam 56 between the longitudinal beams 54 and 55. The said shaft 64 is provided upon its rear end with a crank-arm, 65, carrying'a wrist-pin, and between the said crank-arm and the cross-bar 53 a spur-wheel, 66, is attached to the shaft. A second shaft, 67, is also journaled in the transverse beam 56 and cross-bar 53, parallel with the said shaft 64, which shaft is provided in similar manner with a spur-wheel, 68, and a crankarm, 69. The spur-wheels 66 and 68 of the two parallel shafts 64 and 67 are made to mesh, motion thereby being communicated through the axle 11, the spur-wheel 57 and pinion 58, and the bevel-gear 62 and pinion 63 to the parallel shafts 64 and 67.

An auxiliary rake is attached at each side of the loader near the lower end, which rakes are given an inclination to the front, whereby they extend diagonally from the elevator, so that the hay collected by them will tend to find its Way to the main or central rake and be forced up the elevator, together with the hay collected by the main rake, through the medium of the reciprocating rake-bars 30.

The side rakes each consist of a rectangular head composed of two parallel side bars, 72, and two connecting end bars, the outer end bar, 73, of which projects rearwardly beyond the side bars, as best illustrated in Fig. 2. From the said projecting end bar, and likewise from the front bar of the head, hangers 74 are projected downward, and in the lower end of the said hangers a wheel, 75, is journaled, the said wheel and hangers being adapted to support and ride the side rakes.

Upon the forward side bars, 72, of the heads of the side rake-frames a series of rearwardlycurved teeth, 7 6, are secured, the lower ends of which teeth engage with the ground. The teeth, which consist of suitable steel wire, are held to the ground or prevented from rising too far therefrom by striking an obstruction through the medium of staple-like guides 77, attached to the top of the rear side bar over IIO the rake-teeth, as best illustrated in Figs. 1, 2, and 3.

The side rake-heads are provided at or near their outer end with a brace-bar, 7 8,which bar extends diagonally forward to a pivotal connection with the lower end of the main framestandard 15, and the inner ends of the said rake-heads are likewise pivotally connected to the pieces 19 of the elevator-frame of the loader through the medium of a verticallyadjustable bar, 79, attached, respectively, to the side of the elevator and the forward side of the rakc-head, as best illustrated in Fig. 1.

Below the side rake-head and somewhat to the rear of the same, forward of the teeth 76, a shifting device is suspended from the side rake-heads, consisting of an essentially-rectangular frame, 81, from the rear side of which a series of inwardly-inclined fingers, 82, are projected, which fingers may be straight and rigidly secured to the frame or be constructed similar to the fingers 31, located upon the reciprocating elevator-bars 30.

The frame of the shifting device is suspended from the rear bar of the side rakeheads, and, as the said shifting device is purposed to reciprocate to and from the sides of the loader, the suspension is effected through the medium of a guide-rod, 83, the inner end secured to the upper face of the rear bar of the frame at or near the center and extending outward at an inclination forward and inward, beyond the outer end of the said bar of the frame, from whence it is carried downward and inward, the lower end, 83 passed through an eye, 85, and held in position by a set-screw, 86, as best illustrated in Fig. 3, and from the rear extremity of the projecting arms 73 of the side rake-heads a bar, 84, is downwardly extended, terminating in an eye, which eye encircles the upper inclined portion of the guide-rod.

The inner end of the frame of the shifting device is bifurcated, and in said end one eX- tremity of a connecting-rod, 85 and 86, is respectively pivoted, the opposite end of said connectingrods being attached to the eX- tremity of crank-arms 65 and 69 through the medium of wrist-pins thereon. Depending arms 90 are secured to the side bars, 12, of the frame, the lower ends of which are slotted and form supports for the bars 86, as clearly shown in Figs. 2, 3, and 4.

The connecting-rod 86 is united with the crank-arm 65, and the connecting-rod 85 with the crank-arm 09. The said crank-arms (35 and 69 are so attached to their shafts 64: and 67 that their extremities will at all times extend in the same direction. Thus it will be observed that when the shafts 64 and 67 are rotated the shifting device of one side rake will be carried outward and the shifting device of the rake upon the opposite side be drawn inward, one shifting device delivering the hay to the main rake, the other normally preparing for suchdelivery.

' In operation, as the implement or machine is drawn forward, the main rake carries up the hay to a contact with the fingers 31, attached to the carrying-bars 30, which bars, through the medium of the crank-shafts, the shaft 47, and the drive-wheels, are alternately reciprocated, one set of bars engaging the hay and carrying it up from the main rake as the other set essentially release the hay previously carried up. Thus the hay is without interruption carried forward from the bottom of the loader to the top and delivered into any convenient conveyance. The tendency of the side rakes, which are at an angle or a rearward inclination to the body of the loader, is to feed the hay collected by them beneath the body of the loader and in the track of the main rakes. This transfer of the hay is greatly facilitated through the medium of the shifting devices attached to the side rakes, which devices reciprocate in the same direction, whereby as one of the shifting devices is carried in direction of the body of the loader it passes down the inclined plane of the traveler, engaging with the hay collected by the side rakes, and carries the same in a body almost directly within the track of the said main rakes, while the shifting device upon the opposite side, which is projected away from the body of the loader, passes up the inclined plane of the traveler, whereby the teeth are elevated, and upon the neXt movement of the carriers the outermost shifting device, passing down the traveler, engages the hay upon that side and feeds it to the main rakes, and so on until all the hay desired is collected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
