HAY-STACKER.

SPECIFICATION forming part or Letters Patent No. 716,738, dated December 23, 1902.

Application filed May 7, 1902.

To aZZ whom it may concern.-

Be it known that I, MARVIN H. MOONEY, a citizen of the United States, residing at Gault, in the county of Grundy and State of Missouri, have invented certain'new and useful Improvements in Hay-Stackers, of which the following is a specification.

This invention relates to certain new and useful improvements in hay-stackers of that type in which the fork is carried by swinging arms mounted to move in the arc of a circle from a substantially horizontal to a substantially vertical position; and the purpose of the present improvement is to embody in a device of this class two stackers connected for simultaneous operation, whereby when one is elevated and delivering its load the other is lowered to receive a load or jag, the two stackers being so organized as to practically counterbalance and operated by a horsepower from which extend cables or the like, the slack on one cable directly operating in connection with one stacker loosening the remaining portion of the cable connecting with the other stacker.

A further object of the invention is to facilitate the formation of a stack and elevate more hay or straw within a given time by;

the same amount of power than is usually required to operate one stacker and also to embody in each of the stackers, which are cooperatively related, means for topping the stack.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter.

described and claimed.

In the drawings, Figure 1 is a perspective view of a stacker embodying the features ofthe invention and shown arranged in'operative position. Fig. 2 is a rear elevation of one of the stackers shown elevated and a part of the frame supporting the same. Fig. 3 is a detail plan view of an attachment used in connection with each fork for locking the tines in position for topping. Fig. 4 is a transverse vertical section through the supporting-frame for the stacker, showing one of the stacking devices in edge elevation and positions of adjustment in dotted lines. Fig.

vertical section through a portion of the supporting-arms of one of the stackers, showing means for lengthening or shortening said arms. Fig. 7 is a top plan view of the horsepower device particularly arranged for use with the double stacker and showing a portion of the frame of the latter. "Fig. 8 is a longit udinal vertical section through the center of the horse-power, with a portion of one of the base -runners of the stacker frame shown in side elevation.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numerals 1 and 2 designate, respectivcly, elongated runners, which form the base structure for the entire device and with the parts attached thereto are adapted to be dragged over the ground-surface to the place or position where it is desired to erect or form a stack. Secured to the upper edges of the runners 1 and 2 are cross-strips 3, which hold the said runners in positive spaced relation and'in'upright position, the said strips being terminally extended beyond the outer side of the runner 1. The strips 3 for a greater portion of their length are formed with longitudinal slots 4, which extend through the ends thereof connected to the upper edge of the runner 2, and pivotally secured in the said ends of the strips resting on the runner 2 are compensating bars 5, one being located in each strip and steadied in their rising and lowering movements by brace-rods 6, attached thereto and movably connected to the upper edge of the runner 2 on opposite sides of the point of attachment ofthe strip 3. As both stacking devices are similar in construction, one only will be particularly described. On opposite sides of the strip '3 the lower ends of members 7 of the fork-arms are pivotally connected to therunner 1, and cooperating therewith are upper members 8, the respective members 7 and 8 being terminally provided with angular sleeves 9, slidin'gly engaging said members and held in adjustable position in relation to the latter by pins or bolts 10, whereby the arms are made telescopically adjustable to accommodate different heights of the stack during the formation of the latter. It will be understood that the engaged extremitiesof the members 7 and 8 will be supplied with a suit length of said cables which may be found necessary in the operation of the stacker. It is obvious that these stop-cables 11 prevent the fork-arms from swinging over too far, but permit the fork to assume such angle that it will readily become unloaded or allow the charge or jag of hay or straw carried thereby to slip over onto the top of the stack. The upper members 8 are connected to the head of an elevating fork or rake 14, comprising a plurality of tines 15, arranged in parallel planes with the said members 8 and having a corresponding series of angular tines 16 pivotally connected thereto. For ordinary stacking purposes the tines 16 are permitted to occupy the angle shown by Fig. 1; but when it is desired to top the stack the said tines 16 are elevated, as indicated by dotted lines in Fig. 4, and held in such position by a keeper 17, comprising a bar 18, pivotally mounted at its ends to one of the fork or rake bars and adapted to be thrown upwardly under the tines 16. Between the lower extremities of the members 8 and the head of the fork or rake 14E braces 19 are located and connected at opposite terminals, respectively, to the fork or rake head and the lower terminals of the members 8. The braces 19 relieve the fork-arms of strain, particularly when the said arms are elevated orduring the elevating operation thereof, and connected to the free end of the compensating bar 5 are the two ends ofpull-rods or analogous devices 20, which diverge and are attached at their opposite ends to the fork or rake head, the said pull-rods or analogous devices removing the pulling strain direct from the arms of the fork and transferring it to the said fork. These pull-rods oranalogous devices 20 are intermediatelyseparable to accommodate lengthening and shortening of the arms, and when the members 8 of the arms are projected their full extent the upper portions of the pull-rods are used. Then the arms are telescoped, the upper portions of the pull devices are detached from the lower portions of said devices and folded into the heads of the forks, as shown by Fig. 2, and held against movement by the said lower portions of the pulldevices, which then have their upper ends connected to the heads of the forks.

With the improved double stacking organization a particular form of horsepower is used, and comprises opposite runners 22, connected by a cross-strip 23, to the center of which a sweep 24 is pivotally attached on the upper squared end 25 of a center post 26, rotatably mounted and vertically disposed in the said strip 23, the center post having its lower extremity depending below the strip and also squared, as at 27, to receive a cableattach'ing arm 28,'provided with a loop swivel or eye 29 in its outer end for this purpose. Through the medium of the center post 26, constructed as set forth, the sweep 24 and arm 28 are caused to move simultaneously and equally in proportion to their length, and at a suitable elevation in the runners 22 are a pair of guide-sheaves 30, disposed in a horizontal plane and in longitudinal alinement. The sweep 24 is also supplied with suitable draft-attaching appliances, such as a singletree, and is long enough to permit a horse attached thereto to travel around the runners 22. The terminals of an operatingcable 31 or the like are secured to'the eye 29 on the arm 28, and the opposite portions of said cable are passed over the exterior portions of the sheaves 30, the one part of the cable extending away from the inner side of one runner 22 and the other part from the outer side of the opposite runner. That part of the cable which extends away from the inner side of one runner passes over a sheave 32, horizontally disposed in the front extremity of the runner 2 of the stacker organization, directly under the secured end of the forward strip 3, and thence transversely across and through an opening 33 in the forward extremity of the runner 1, over a verticallydisposed sheave or pulley 34 in the end of the strip 3, which projects outwardly over said runner 1, and thence to the free end of the adjacent compensating-bar 5. The other part of the cable 31 passes through a sheave or pulley 35, secured at an intermediate point on the outer side of the runner 1, thence through a pulley or sheave 36 on the end of the other cross-strip 3, and is terminally connected to the adjacent compensating bar 5. It will be seen that the cable 31 through the connection thereof to the arm 28 virtually becomes a continuous cable terminally attached to the two compensating bars.

The purpose of connecting the cable-terminals to the bars 5 is to relieve the pulling strain directly from the arms of the forks or rakes, so as to prevent fracturing or breaking said arms, and the liability to injury of the arms is further prevented by the use of the pull-rods or analogous devices 20, heretofore explained and also attached to the compensating bars.

The horse-power devices, as well as the compound sta'cking structure disclosed, may be simultaneously 'moved from one place to another by dragging the same over the groundsurface through the medium of connectingrods 37, detachably secured to the front ends of the runners l and 2 and the rear ends of the runners 22, as clearly shown by Fig. 7; but after the apparatus as an entirety has been disposed in the position desired the said connecting-rods may be detached and the horse-power moved any distance desired from the stacking organization itself.

When the improved device as an entirety is arranged for use, the parts will be disposed as shown by Fig. 1, one set of armsand their forks being lowered and the other elevated and the horse-power placed at a distance from the front extremities of the runners 1 and 2. To permit the arms of each fork or rake to lower very close to the ground-surface, the upper edge of the runner 2 at the front and rear extremities is formed with slots 38, into which the arms of the forks or rakes are adapted to be depressed, as clearly shown by Fig. 1. The improved device having been arranged in convenient position to the quantity of straw or hay to be stacked, the arm 2' is set in rotative motion by means of adraftanimal, the one fork being first loaded with the hay or straw by an operator, it being understood that the fork or rake which is loaded will be the one that is in lowered position. When the sweep 24; is moved from the position shown by Fig. l in the direction of the arrow, the right-hand portion of the cable 31 will be drawn forwardly by the arm 28, and thereby gradually elevate the forward fork or rake by pulling onthe compensating bar 5, which when the said fork or rake is lowered willstand in an approximately vertical position. The pulling force of the said righthand portion of the cable will be exerted through the compensating bar and the pullrods or analogous devices 20 andconcentrated on the head of the fork or rake, and as the said forward fork or rake is elevated the left-hand portion of the cable is gradually slackened or moved rearwardly and allows the rear fork or rake to lower, and when said rear fork or rake is at its lowest position it is loaded and immediately starts to elevate just at the time that the forward fork or rake is unloaded or has deposited its load on the stack. This elevating operation of the rear fork will occur when the sweep 24 arrives at a point approximately opposite that shown by Fig. '1, and simultaneously the forward fork will begin to lower, and thus the alternate elevating operation of the two fork structures is carried on regularly withoutreversing the draft-animal and during the continuous movement of said animal in one direction. This is due to the fact that when the arm 28 terminally arrives in its closest relation to the two sheaves or pulleys 30 of one runner 22 all the slack necessary in the one portion of the cable to permit the fork or rake structure controlled thereby to fully lower will have been exhausted and the pulling strain on the other portion of the cable necessary to elevate the remaining fork structure will have been completed, and immediately the fork structure that has been lowered will start to rise or elevate and the one that was elevated will lower. By this means a stack may be quickly formed, and in view of the fact that the two fork structures counterbalance each other or are exact counterparts in weight the draft-animal is only required to lift approximately the same load weight, and, in fact, the load weight will be slightly decreased in view of the assistance in pulling the cable, due to the lowering of the empty fork structure.

The improved device is comparatively simple in its construction, and in view of the economicaloperation and expedition resulting in the formation of a stack owing to the dual fork organization a very useful farming implement will be produced.

Having thus fully described the invention, what is claimed as new is 1. A hay-stacker having dual fork structures adapted to be alternately raised and lowered by pulling power applied from a single source.

2. A hay-stacker having dual fork structures and power appliances adapted to alternately elevate and depress the same.

3. A hay-stacker having dual fork structures of equal weight adapted to alternately elevate and depress, and a cable device connected to the said structures and actuated from a single power-producing medium.

4. A hay-stacker having fork structures adapted to alternately elevate and depress, the elevation of one structure assistingin the depression of the other and vice versa.

5. A hay-stacker comprising a pair of independent fork organizations, and operating devices correlatively connecting said organizations whereby when one is elevated the other will be depressed, and vice versa.

6. A hay-stacker comprising a pair of independent fork organizations movably mounted to alternately elevate and depress, a horsepower having an arm, and anoperating pull device made continuous through attachment to said arm and terminally connected to said fork organizations.

In testimony whereof I affix my signature in presence of two witnesses.
