WILLIAM E. ARNOLD, or WATERVILLE, KANSAS.

I-IAY-STACKER.

Application filed August 22, 1912.

To all whom it may concern:

Be it known that I, WILLIAM E. ARNOLD, citizen of the United States, residing at WVaterville, in the county of Marshall and State of Kansas, have invented certain new and useful Improvements in Hay-Stackers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to hay stackers, and has for its object the production of a hay stacker which will cause the hay stacker to be swung as soon as the hay fork has been lifted to the desired position.

Another object of this invention is the production of an efficient supporting standard and means for engaging the lifting crane whereby the hay fork may be efliciently swung after the same has been lifted to the desired position.

l/Vith these and other objects in view, this invention consists in general of certain novel details of construction and combinations of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the drawings, Figure 1 is a perspective view of the hay stacker. Fig. 2 is a central vertical section through the supporting joint for the hay crane. Fig. 3 is a diagrammatic View in top plan of the supporting standard showing the manner in which the same is wound around the supporting standard before the crane has been swung. Fig. 4 is a diagrammatic view of the crane and stacker showing the position of the crane after the same has been swung.

By referring to the accompanying drawings by numerals, it will be seen that 1 designates the base frame which may be supported upon wheels 2 for conveying the frame from place to place. These wheels 2 are carried by the axles 3 which are journaled in the side members of the frame 1. Of course, it should be understood that the frame may be used as a sled when so desired by removing the wheels 2, and for this reason the side members of the frame 1 are beveled as indicated at 4. The base frame 1 is provided with a pair of parallel, centrally arranged, supporting cleats 5, and the outer ends of the side members of the supporting frame 1 are connected by means of the transversely extending brace members 6. A central supporting standard 7 is carried by the centrally arranged, transversely ex- Specification of Letters Patent.

tending members 5, and has a downwardly projecting tongue 8 fitting between the parallel members 5 to assist in supporting the standard 7 in its vertical position. The standard 7 is provided with flattened portions 9 upon the corners thereof, and diverging braces 10 are secured to the standard 7 at their upper ends as indicated at 11. The lower ends of the bracing members 10 are secured to the supporting frame 1.

The standard 7 is provided at its upper end with a socket 12, which socket is lined with a metallic lining 13 for receiving the pivot pin 14 of the crane supporting yoke 15. This crane supporting yoke 15 is substantially U-shaped in cross section and carries between its upwardly extending arms a pivot bolt 16, upon which pivot bolt 16 is pivotally mounted a crane member 17. A bracket member 18 straddles the crane l7 and is provided with a pair of upwardly extending arms which carry at their upper ends a pin 19 over which passes the bracing cable 20. This bracing cable 20 is secured at its respective end to the crane 17 as indicated at 21. By means of pivotally securing the crane 17 to the standard 7 in the manner described, it will be seen that the crane may be easily swung when so desired both vertically and horizontally.

The crane 17 carries at its forward end a pulley 22 and also carries a centrally arranged pulley 23. A hay fork lifting cable 21 passes over the pulleys 22 and 23 and also passes over a pulley 25 carried by one of the transversely extending members 5 as illustrated in Fig. 1. Draft means may be attached to the swingletree 26 for raising the hay lifting fork 27, which hay lifting fork is attached to the opposite end of the cable 24. The hay lifting fork 27 carries a depending cable 28 for allowing the hay lifting fork to be lowered when it is so desired. The hay lifting fork 27 may be of any desired form for accomplishing the desired purpose. A swinging chain 29 is connected to the rear end of the crane 17 as indicated at 30, and the opposite end of the swinging chain 29 is connected to the standard 7 by means of a securing eye 31.

When the device is in operation the forward end of the crane 17 will extend upwardly so as to have the hay placed upon the lifting fork 27 at which time the swinging chain 29 will be wound around the crane 17 in a spiral manner. As the hay lifting fork 27 engages the crane 1 7 and the horses continue to pull upon the cable 24, it will be seen that the crane 17 will be swung for the reason that the swinging chain 29 will be compelled to unwind from the supporting standard 7 owing: to the fact that the PIES? hay loading device.

From the foregoingdescription, it will be seen that a very simple and eflicient device hasjbeen produced whereby the crane will be automatically rotated "on swung as soon as the hay lifting fork has comein engagement with the crane 17 through the medium of'the'. chain '29 which is {adapted toxbe wound around the standard 27, and which chain will unwind as the "draftmeans continueslto pull upon the cable 24:- Of course, it should be understood that as the crane is being swung or rotated upon the standard the forward end of the crane .willbe caused to be swung downwardly.

(It should, of, course, beunderstood that when the hay: fork is flOiLdGdQthGhfiY fork will rest upon the-groundand after the fork is loaded the draft animal which is attached to the tree26' will moveaway from the hay'lifting devicethereby raising thehay lifting fork-up upon the pulley 22. The arm 28, of the fork will then come in contact with'the pulley by the continual pulling upon the cable 2 1 and the vdraft animal will cause the forward end of the beam 17'to swing around at right. angles to the positionas shown in Fig. 1. This swinging movementwill, of course, cause the forward end of thebeam 17 to swingdownwardly owing to the factthat the pressure of the swinging chain 29 will be relieved from the rear end of the beam 17 owing to the fact .that this chain will be unwound from the standard 7.

VBy carefully considering the drawing, especially Fig. 1, it will be seen that the forward end of the beam or boom 17 is, kept M29155 wound around the standard 7, and as elevated for the reason that the chain this chain 29 is wound around the standard Y 7 it will'be-seenthat the length of the chain 29 will be reduced thereby bringing the lower end of thebeam or boom 17 in closer engagement with the standard 7. When the boom 17 swlngs at right angles 'to' the posi-- tion shownin Figh-Zl, it will-be seen thatthe I chain 29will be unwound from the standard thereby allowing additional swinging movement'of theboom 17.

Having thus Y described the invention, what is claimed as new, is

In a -hay"loader, the combination with a supporting frame, of a centrally located standard provided with a cylindrical upper end, aboom-pivotally -mounted='upon said standard and capable of 'rotating thereon,

means for pivotally -supporting said booing for vertical swinging movement, a flexible means connectedyto the rear'end of said boom, and'passing around said cylindrical upperend of said' standard and being secured to one. side of said standard,- a hay lift' ing fork, a cable-carriedzby. said boom and supporting-said hay lifting fork, and said cable adapted to'ca'use said boomto swing as pressure ls-brou'ghtto bear upon said cable, said flexible means engaging said boom being adapted'to be unwound'from said standard as said boom -isrotated for causing 'fthe outer ,end of said boom to be lowered as saidboomis rotated.
