Application January 5, 1945, Serial No. 571,447

2 Claims.

This invention relates to haymovers whereby hay or other materialmay be lowered from or raised to a point horizontally distant from the point to which the material is lowered or from which it is raised.

The device is of simple construction and may therefore be manufactured at low costs. While it is described and illustrated as lowering hay from a loft not shown to a point horizontally distant from the latter, it may be used in places other than a farm and also for raising a load.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of the haymover in raised position prior to the lowering operation.

Figure 2 is a front elevation of the mover.

Figure 3 is a top plan view of the device.

Figure 4 is a vertical section of the mover on line 4-4 of Figure 3.

Figure 5 is a transverse section through a haytrack and side view of a device for controlling the position of the mover.

Figure 6 is a section on line 66 of Figure 5.

Referring to Figures 1, 2, the. hay mover has a fulcrum beam B placed on the floor of a barn or other building in which hay is stored. The beam may carry at one end or both ends an extension E passing through clips 2 secured to the beam and controlling the movement of the latter and of the structure supported thereby. A pair of upwardly converging struts 3 is secured with its lower end to one side of the beam and another pair to the other side thereof. The pairs are in upwardly diverging relation and carry at intermediate points bracer 4 and at their upper ends a platform 5. Each strut may be composed of overlapping sections a, b, bolted (6) together and may be extended or shortened as the occasion may require.

In the lower portions of sections b are additional boltholes 1. On the lower sections are button like attachments 8 around which the ground end of the rope may be coiled or tied while the platform is being loaded. Beneath the latter are diagonal braces 9. On the top of the platform and in adjacent corners thereof are eyes It] to which the ends of a rope I I or other flexible member are secured. At the midpoint such rope is aifixed to the depending frame I2 of a pulley l3 over which a longer rope 15 passes. One end of the latter is attached to the lower end of a carrier frame l3 traveling on a track T depending from the roof of the building. The last named rope passes from the pulley named upward and over another pulley l4 secured to the carrier and thence downward. On the track is a haycarrier H having a fork or other hay-supporting means.

The operation of the device is as follows:

Hay is to be placed some distance in front or behind the mover (Figure 2) The vertical length of the mover is so chosen that the platform is just beneath a batch of hay held by the fork of the carrier. After the platform has been loaded with the hay, the ground end of the rope hitherto held by one of the buttons is released therefrom and the hay supporting structure is slightly tilted forwardly or rearwardly and its downward swing is controlled by the ropes. When the mover is in horizontal position the hay has not only been lowered but also moved horizontally a distance equal to the height of the mover.

Obviously hay can also be raised by the reverse operation.

Owing to the mechanical advantage of the rope and pulley arrangement a pull on the ground end of this rope can balance a load on the platform having twice the value of the pull.

Having thus described and illustrated the preferred form of my invention, it is understood that changes may be made that do not depart from the spirit of my invention the scope of which is defined in the appended claims.

While the block and tackle of my apparatus is of the simplest kind involving a mechanical advantage of l to 2, other mechanical devices involving a greater advantage may be used.

I claim as new:

1. In a load mover, a fulcrum member pivotally supported, struts secured to the member and composed of adjustable sections rising therefrom and braced at intermediate points, a platform supported at the top of the struts, a flexible member attached with its ends to one side of the platform and its midpoint to a pulley, a second flexible member passing over the pulley and having one end secured overhead and having its intermediate portion passing over a pulley secured overhead and its remaining portion extending downward, and means for connecting the ground end portion of the second flexible member to one of the struts.

2. In a load mover, an overhead carrier including means for holding and dropping or receiving a load, downwardly converging platform means for receiving or delivering a load to the first means and being pivotally supported, means for controlling the descent or rise of the platform involving a mechanical medium, and an attachment on the platform means for holding the controlling means, said downwardly converging platform means being vertically adjustable.

WILLIAM WEDOE.
