Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed June 2, 1908. Serial No. 436,258.

T 0 all whom it may concern:

Be it known that l, JOSEPH A. Sorrrnrz, a citizen of the United States, residing at Marquette, in the county of Hamilton and State of Nebraska, have invented certain new and useful Improvements in Hay-Stackers, of which the following is a specification.

This invention relates to an improved hay stacker, and has for one of its objects the provision of means for elevating hay or other like produce to an unusually high altitude; another object is to provide means for use in forming more than one stack without changing the position of the stacker.

The invention includes certain devices found to be convenient for operating the parts, and includes features relating to durability and economy of construction, and to adjustable means for increasing the sweep of the fork.

With these and other objects in view the invention presents a novel combination and arrangement of parts as described herein, pointedout by the claims and as illustrated by the drawing, wherein,-

Figure 1 is a side view of a hay stacker embodying my invention, the fork being in a lowered position; areinforcing-rail being shown broken away to disclose the pivotal mounting of the frame. Fig. 2 is a somewhat similar view to that shown in Fig. 1, the fork being elevated; the base support being partly broken away. Fig. 3 is a rear view of parts shown in Fig. 1, the operating crane or lever being sectioned at its pivotal mounting. Fig. 4 is an enlarged detail relating to Figs. 1, 2 and 3, to clearly show relative position of parts, the guide-rail being partly in section. Fig. 5 is a plan view of the locking-bar and a part of the guide rail and swing-lever, said rail and lever being partly in section. Fig. 6 is a plan view of the fork, lifting arms and holding-plate, a part of the forkcontrolling cable being also shown. Fig. 7 is a view of the rear end of the fork.

Referring now to the drawing for a more particular description, numeral 1 indicates a hay stacker which may be provided with any suitable base 2 so that the revoluble and up right frame 3 may be sustained, substantially in a vertical position.

Base 2 may be conveniently constructed ",y use of parallel bed-plates 4 upon which are secured side-plates 5, and between the ends of side plates 5 are secured cross-plates 6. I employ a series of bearing-rollers or wheels 7 pivotally mounted upon and sustained by straps 8, these straps belng secured upon and extended above plates 5 and 6.

' The parts thus described provide a suitable and inexpensive supporting base, preferably rectangular in form, since stacks are to be formed upon either side of it, as will be seen. Rollers 7 are preferably mounted oppositely disposed, as pairs so that the weight of the upright, revoluble frame 3 may be adequately sustained.

I provide the disk 9 having its center pivotally mounted by pin 10 traversing the middle of the disk and base block 11, said base block bein secured between side plates 5. The upright frame 3 consists of four corner posts 12, one of which, however, for convenience is indicated at 12; an upper structure is added to these posts, as will be described. These corner posts have their lower ends secured upon and near the outer edge of disk 9 at equal distances apart, and reinforcing rails 79 may be employed, as clearly shown, for securing the posts. Said posts extend upward convergently, and attheir upper ends and upon their outer sides 1 preferably employ inverted U shaped plates 18, which operate as reliable securing means; the posts are also held in fixed relation to each other by the horizontal U-shaped holding-plate lel, having parallel arms 15 secured upon plates 13. I do not wish to be understood as limiting myself to the exact details mentioned, and other means may be employed, if desired, for securing the corner posts. in elevating large loads of hay there is a considerable strain upon the frame, and all of the parts should be adequately sustained.

Lifting-arms 17 are sustained upon arms 15, their pivotal mounting being shown at 16. Arms 15 are apertured near their ends as shown at 18, to furnish a pivotal mounting for arms 17 when it is desired to elevate fork 19 to an altitude greater than it would be elevated when mounted as at 16.

Frame 3 is extended upward to its apex 20 from the upper ends of posts 12 preferably as an iron structure, employing legs 21 suitably secured upon said posts. The material used or particular form of this upper structure is notimportant, however. so long as a suitable mounting is provided for operating-lever 22, and for pulley 23. The operating-lever or crane 22 is pivotally mounted at 24t upon plates 25, these plates being secured upon legs 21. Between plates 25 and apex 20 are secured plates 26 upon which pulley 23 is mounted. As thus described, operating lever 22 is mounted to swing in the same direction as arms 17. Longitudinally disposed upon each arm 17 is secured rod 27 upon which is a ring 28, and I employ a pair of connecting cables 29, one end of each cable being secured at 82 to the front end of operating lever 22, the opposite ends of these cables being connected to rings 28. Upon the rear end of lever 22, at 83, is secured cable 30, which passes over pulley 31, secured upon the rear of base 2, and any suitable power may be employed for drawing the cable; and as is apparent, a movement of this cable when drawn outward, will operate lever 22 to raise liftingarms 17.

Fork 19, best shown in Fig. 6, comprises tines 32 secured by cross-piece 33, and, in order that provision may be made for a suitable mounting of the fork upon arms 17, the tines'are assembled in groups, as the central group 34 and side groups or pairs 35. I employ inclined braces 36 extending upwardly from the rear end of pairs or groups 35 to posts 37, the latter being secured transversely upon the rear end of tinegroup 34, and by this construction an open space or recess 38 is provided, within which extensions 39 of lifting-arms 17 may pass to pivotal mountings 40 upon crosspiece 33, and upon the lower part of the fork. Posts 37 are supported by braces 41, and upon the upper end of these posts are secured longitudinal rods 42, having thereon, rings 43.

Arms 17 are secured together by cross pieces 44 and 45, and by diagonal braces 46, and upon the middle of cross piece 44 is secured pulley 47. I employ cable 48, having end-portions 49 secured to rings 43; cable 48 engages pulley 47 and passes over pulley 23 upon frame 3, and thence passes clownward to sustaining-bar or latch'50 upon which it is secured, as shown at 51. As thus described, the fork may have a swinging movement under control of cable 48. As shown in Figs. 1 and 2, posts 37 are substantially vertical, and tines 32 are horizontal. These posts remain vertical while the fork is being elevated. After a'load has been placed upon the fork, the rear end of operating-lever 22 may be lowered by the power employed; this movement will raise arms 17 and the load will thereby be elevated, bar 50 remaining'stationary at this time and sustaining fork 19, so that posts 37 remain in a vertical position while the load is moving upward; and posts 37 remain vertical, under control of latch 50, until the forkis dumped, and this operation will presently be explained. 7

Secured upon and near the rear ends of side, base-plates 5 are posts 52, upon the top of which is secured engaging-rail 53, having notches 54, within which may be held the rear end of swing-lever 55, the latter having a pivotal mounting at 56 upon one of front posts 12.

Between rear posts 12 and 12 is mounted the reel or drum 57 upon one end of which is mounted the ratchet-wheel 58 engaged by the pawl 59. Upon lever 22, between its rear terminal and its pivotal mounting 24 is secured, at 60, the end of cable 61, the opposite end of this cable being secured in groove 62 of the reel. 1n groove 63 of the reel is secured cable 64, and to cable 64 is secured the weight 65.

Upon the rear post 12 is secured the guide-rail 66 which extends, substantially, parallel with and inwardly of post 12. This guide rail is extendeddownward, and near its lower end is formed to provide the recess 67 and shelf 68.

Upon the lower part of corner post 12' and upon its outer side, 1 construct the guiderail 69, the same being disposed longitudinally thereon and having an aperture 70 near its upper end adapted to receive therein, trip-rod 71, said rod having one end pivotally mounted at 72 upon the outer end of pawl 59, its opposite terminal being disposed adjacent lever and, upon occasion adapted to make contact with said lever, for purposes hereafter explained.

I provide the locking-bar or keeper 73, pivotally mounted at 74 upon swing-lever 55. Between keeper 73 and lever 55 is provided the spring 7 Guide-rail 69 is apertured at 76, and the inner end of keeper 73 is transversely bent to form the finger 77. By reason of the resiliency of spring 75, finger 77 normally presses inwardly to engage within aperture 76, and as shown by Fig. 5, may enter recess 81 to thereby detain lever 55 in a fixed relation within one of recesses 54 of rail 53.

1 provide the detaching-bar 78 mounted upon the outer part of the guide rail 66. The latch or sustaining-bar 50 has its pivotal. mounting at 80 upon a front corner post 12; it passes within guide-rail 66 and its free end passes rearwardly of recess 67, and this latch is adapted to have a seating, near its end, within said recess, in contact with and beneath shelf 68. By manually swinging said bar 78 in an inward direction, latch 50 will be dislodged from shelf 68, thereby allowing the latch to swing upward, and it is obvious that this operation will permit tines 32 of the fork to move to a vertical position, and this constitutes the means for dumping or unloading the fork.

From the description thus given it will. be understood, that when the rear end of operating lever 22 swings downward, it is detained by pawl 59, since weight 65 causes reel 57 to revolve, and cable or strand 61 becomes wound upon the reel. Ratchet 58, upon the end of the reel, is engaged by the pawl, and after the rear end of operatinglever 22 has been lowered. to the position shown in Fig. 2, it is securely held by the pawl. At this time, the fork is in an elevated position, and its tines are horizontal for sustaining thereon the load which theretofore was placed thereon. During the movement just described, c: ble is dr wn outward to pass upon pulley 31, and this movement is aided, somewhat, by weight As soon as the fork has been elevated, the operator manually presses the outer end of lever 7 3, sidewise, in a direction of lever thereby raising finger 77 from aperture 76. Lever 55 is then raised upward siiilficiently to lift it from recess 5 1 of rail 53. Frame 3 may then be readily rotated 90 degrees, in either direction, by the operator, by pushing or pulling lever 55, sidewise, whereby fork 19 is moved sidewise to the location of the stack. After the fork has been thus moved to the desired position, it is dumped, by manually moving the detaching-bar 78, as already described. The operator then swings frame 3, to carry fork 19 away from the stack, and by then raising lever somewhat further, it will make contact with the lower end of rod 71, which will raise this rod, thereby carrying pawl 59 out of engagement with the teeth of ratchet wheel 58, which releases operating-lever 22.

As soon as lever 12 has been released, its front end will move downwarr arms 17 and fork 19 having similar movements. The parts are so balanced that the fork and arms 17 have a weight somewhat greater than weight 65 plus the weight or friction of other parts to be overcome, and, in operaation arms 17 swing downward with a gradual movement, as soon as the reel has been released from the pawl, and this, as has been seen, is under control of the operator, who, at the proper moment, raises lever to push upward the trip-rod 71. By repeating the operations, as described, successive loads may be carried from the ground to the stacks, and these stacks may be formed upon either or both sides of the stacker.

I have shown a plurality of recesses a l formed in rail 53, and in operation, swinglever may be inserted in any of these recesses, as desired.

During the revoluble movements of frame 3, the weight of the several parts is sustained upon rollers 7 these rollers have a broad surface for contact with the lower surface of disk 9.

Operating-lever 22 may have a greater length than shown, if desired, and by reason of the power derived from this lever and by use of weight 65, very large loads may be moved by the fork.

Rods 27 are constructed so that when arms 17 are mounted. in apertures 18 of plate 15, said rods will have an adequate length to sustain rings 28 together with strands or cables 29, for the front end of the operatinglever.
