2 Claims. (Cl. 212-83) This invention relates to apparatus adapted to be set up in an open field for the purpose either of stacking hay or removing hay from a stack.

Heretofore difiiculty has been experienced in ordinary carriers of this type because it has been practically impossible to bring the wagon into proper relation to the carrier and, as a result, the load being conveyed has not been able frequently to clear the stack.

An object of the present invention is to provide a simple and efficient apparatus which can be set up readily in a field and can be adjusted to different heights, said apparatus including an extension for the carrier under which the body of the vehicle to be loaded or unloaded can be positioned so that the hay can readily be lifted therefrom and lowered thereto and can be transported at a high level so that hay thus can readily be lifted from or deposited upon the center of the stack.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of the apparatus in position adjacent to a stack, portions being broken away.

Figure 2 is an end elevation.

Figure 3 is an enlarged vertical transverse sec-- tion through the skeleton beam and the track thereunder, the carrier being shown suspended from the track, said section being taken on the line 33, Figure 1.

Figure 4 is an enlarged central vertical transverse section through the carrier.

Figure 5 is a vertical longitudinal section therethrough.

Referring to the figures by characters of reference A designates a skeleton beam of any desired length formed preferably of three angle strips indicated at l, 2 and 3 which are joined by triangular straps l regularly spaced so that the resultant beam is substantially triangular in cross section with a fiat top and with downwardly converging sides, as shown particularly in Figure 3. The ends of the beam can be closed by means of triangular plates 5 which also serve to stifien the beam and constitute a means for attachment to hangers 6. These hangers have heads I at their upper ends from which are extended stems 8, the stems at the two ends of the beam projecting in opposite directions but being in alinement.

The beam is reenforced longitudinally by a truss 9 in the form of a rod secured at its ends to the top of thebeam at the center of the ends thereof andsecured at its center to the center of the bottom of the beam.

Depending from the bottom strip 3 and the triangular connecting strap 4 are rods H] the lower ends of which are secured to cross strips I I which, as shown particularly in Figure 3, have angle strips 12 secured on the end portions thereof. These strips are oppositely disposed with upwardly extending flanges cooperating to form a track. This track extends throughout the length of the beam A and one end of the track is also extended well beyond the adjacent plate 5 to which it is connected by a bracing rod I3.

Depending from the track at a point adjacent to the center of beam A is a strip M.

The beam A is adjustably supported by telescopic standards B formed of an upper angle strip l5 and a lower angle strip It, the two being slidably connected so as to telescope one upon the other and being held against relative displacement by guide bands H which embrace the strips, the lower band being secured to the upper strip I5 while the upper band I! is secured to the lower strip it, these bands being slidable along the opposed strips. The construction is so obvious that detailed illustration thereof is not deemed necessary.

A pulley I 8 is carried by the upper end portion of each of the lower strips l6 and a drum or windlassl9 is carried by the lower portion of said strip l6. To this drum is secured one end of a cable 20, said cable being extended upwardly over pulley l8 and thence downwardly, its other end being attached to the lower portion of strip l5 as indicated at 2 l A carrier has been indicated at C. This can be of the same general construction as the carrier shown in Patent No. 1,421,102, issued to me on June 27, 1922. The carrier is provided with wheels 22 adapted to travel along the track I 2. Sheaves 23 are carried by the lower portion of the carrier. Arope 24 is fastened at 25 to the carrier and has a free end portion 26 extending in one direction from the carrier. The other end portion of the rope extends in the opposite direction thereof and longitudinally under the track 12, it being movably supported at one end of the track by a pulley 2?. The rope 24 is provided with a bight 28 depending from the carrier C and this bight supports a sheave 29 having a hook 3B and an upwardly extending eye 3|. This eye, when raised, is adapted to engage a latch 32 and means are provided in the carrier whereby the latch can be released when it comes into contact with the trip [4. This means can be in the form of a slide 33 adapted to drop into the path of a portion of the latch when said latch is elevated into holding position. The construction of the carrier and the parts associated therewith is substantially the same as disclosed in my patent hcreinbefore mentioned and, therefore, constitute no part of the present invention.

When it is desired to set up this apparatus for the purpose of stacking hay, the standards B which are provided at their upper ends with :3

sleeves 34 journalled on the stems 8, are set up so as to converge upwardly, thereby supporting the skeleton beam A above the point where the stack is to be located. By means of the windlasses l9 and the cables 20 these standards can be elongated so as to raise the beam A as far as desired. Suitable means, such as pawl and ratchet mechanism 35 will of course be provided for each Windlass so as to prevent retrograde movement of the Windlass after the standard has been elongated. This ratchet mechanism is of the conventional form aand detailed illustration thereof is not deemed necessary.

Before the parts are set up as explained the carrier is of course placed on the track l2 and the rope adjusted. This carrier is free to move longitudinally of the track and when it is on the extension of the track as shown in Figure 1, it can support the hook 30 and any hay fork or the like which may be suspended therefrom, directly over the load to be carried. By paying out rope 25. the sheave 29 can be lowered for engagement of its hook with the load and thereafter, by pulling on one end of the rope 2 1, the load can be elevated and the carrier drawn along the track [2 to a point exactly over the center of the position where the stack is to be formed. At this point the trip l4 will release the sheave 29 for gravitation with its load, in

an obvious manner. Thereafter by pulling on the other end of rope 24, the carrier can be moved in the opposite direction on track I2 and between one pair of standards B so as to assume a position on the extending end portion of track l2 directly over the load to be carried. The operation can then be repeated. Obviously the foregoing operation would be reversed should it be desired to remove hay from a stack and transfer it to a vehicle.

Importance is attached to the fact that the track is suspended from a skeleton beam. This provides strength and lightness and enables a track of considerable length to be utilized in connection with the apparatus.

What is claimed is:

1. Apparatus of the class described including a skeleton beam comprising connected spaced strips, end plates secured to said strips, hangers extending therefrom, stems projecting from the hangers, a pair of standards pivotally connected to each of the stems, all of the standards constituting means for supporting the skeleton beam, each of said standards comprising telescopically connected members and means for shifting the members relative to each other, a track suspended from the beam and having one end portion extending between the standards'of one pair and beyond the end of the beam, a brace connecting the outer end of the extension portion of the track to one of the stems, and a carrier movable along the track and onto and off of the extension.

2. In apparatus of the class described the combination with adjustable supporting elements, of a structure mounted therebetween and including angle strips disposed in parallel relation, connections therebetween, said strips and connections providing a skeleton beam angular in cross sectional contour, a truss rod secured at its ends to the end of said beam and at its center to the bottom thereof, a track parallel with and below the beam and having one end extending therebeyond, spaced connections between the track and the bottom of the beam, and a supporting connection between the projecting end of the track and one end of the beam.
