HAY-UNLOADING nrrnnnrus.

To all whom it mayconcem:

Be it known that I, ALBERTULOH, a citizen of the United States, residing at Chelsea, in the county of Tamaand State of Iowa, haveinventedcertain new and useful Improvements in Hay-Unloading Apparatus, of which the following is a specification, reference being vhad to the accom panying drawings.

" unloading apparatus and has for its. pri- It is a further objectofthe invention to provide an apparatus for the above purpose, which is simple in its construction,.highly serviceable and convenient inpractical use, and maybe manufactured and installed at relatively small cost. I

With the above and other objects in View, my invention consistsin the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the ac companying drawings, in Which, t t Figure 1 is a side elevation of my improved yhay unloading apparatus" showing the carriage in its dischargeposition within the barn; Fig. 2 is a similar view, the carriagebeing disposed exteriorly of the barn in its load receiving position; Fig. ,3 is an elevation on an enlarged scale of the weight ed cable pulleys, illustrating the connections of the cables; Fig. is a side elevation of the drumcoperating gearing; and Fig. 5 is a topplan view thereof. l

Referring in detail to the drawings, 5 designates a longitudinally extending track Specification of Letters Patent;

This invention relates to an improved hay which is suitably mounted in the top of the barn and at one of its ends extends exteriorly thereof. Upon this track, the traveling carriage 6 is arranged and is provided. with a hay fork indicated at 7. The

track, carriage and fork may be of any or- I dinary or approved construction, said fork being equipped with the usual trip device whereby its load may be released. 8 indi cates the cord extending from the trip device, wherebythe same may be actuated.

Upon the inner end of the elevated track 15, afpulley or sheave 9 is suitably; "mounted, and asecond pulley or sheave 10 is also supported by the track adjacent to the pulley 9.

11 indicates a suitable yoke or frame in I which a pair of pulleys 12 are rotatably mounted,the axes of said pulleys being in vertical alinement. To the lower, end of this yoke frame, suitable weights 13]. are

tional pulley 14 is mounted in bearing arms 15 depending from the frame 12. Ina suit able support 16 fixed to the floor or other suitable stationary part ofthe barn structure, a pair of pulleys 17 are rotatably mounted. "One end of a rope or cable 18 fixed, and between these weights an addiis attached to a bail 19 depending from the axis of the pulley 14:. This cableiis carried downwardly. around the uppermost pulley 17, and then upwardly around the pulley 14 and again downwardly and around the lower pulley 16. From this lower pulley, the cable 18 is extended around suitable guide pulleys indicated at 20, and attached to one section of a double drumshown at 21 whichis suitably mounted upon the forward end wall of the barn. The operating means for this drum will be hereinafter described. Acable 22 is also attached at one of its ends to the other section of the drum 21 and passes around a guide pulley 23 and then rearwardly over the guide pulley 9, said cable extending downwardly from" this guide pulley and around the lowermost pulley 12 and then upwardly around the pulleylO, and from the pulley ,lOthe cable extends downwardly around the upper pulley 12 and again 'upwardly,and is fixed at its end'to a bail or loop indicated at 24. A second cable 25 is also attached to this bail and extends downwardly around the upper pulley 12 and then upwardly over the pulley 10 and against downwardly and around the lower pulley 12 and upwardly over the pal-- ley 9. This cable is extended from the latter pulley over a pulley 26 mounted on the carriageffi and under a sheave 27 from which the hay fork is suspended, the end of the cable being suitably secured to one 1 end of the carriage. A cable 28 isalso attached to the forward end of the carriage 6 and extends exteriorly of the barn over a supporting sheave 29 mounted on the exfixed, and with the same a manuallypperable gear 3 L meshes, said gear having a crank handle 85. I p

36 designates guide loops for the cables which are wound upon the drum sections, and it will be noted that the cable which is connected to the weighted pulley block extends around its drum section in one directionwhile the other cable 22 extends around the other drum section in a relatively opposite direction. It will thus be apparent that whenone of the cables is unwound from the drum, the other cable is wound thereon.

In the operation of the device, it will be understood that the weighted pulley carrying block to which the cable 24 is connected, normally tends to pull the carriage inwardly to the inner end of the track 5. Assuming that the hay fork has been supplied with a load of hay, the operator, upon turning the crank of the gear 34C to the right, rotates the drum so that the cable 22 will be wound tation of the gear 3-4, the cable 22 will unwind from the drum while the cable 24: will be wound thereon, thus elevating the pulley block. The weighted pulley 30 on the end of the cable 28 will thusmove downwardly upon the guide cord or cable 32 and the carriage and hay fork will be moved outwardly along the track 5 into position to receive anotherload of hay. In this manner, it will be seen that the device may be operated entirely by one man, and the contents of the hay rack easily and quickly loaded into a barn.

From the foregoing description, taken in connection with the accompanying drawings, the construction, manner of operation and several advantages of the invention will be fully understood. The member indicated at 37, fixed to the under side of the track at its outer end,,is for the purpose of operating the latch device which holds the hay fork in connection with the carriage so that the hayfork may be pulled downwardly in position to receive the load.

It will be appreciated that the apparatus as a whole is comparatively simple in its construction and can be readily installed in an ordinary barn at nominal cost. It will be apparent that the several operating parts of the apparatus may be otherwise mounted and'arranged than as above referred to, and

the detail structural features'of these parts may be variously modified and I, therefore, reserve the privilege of adopting allsuch legitimate changes as will fairly fallwithin the spirit and scope of the invention as claimed.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is e r I 1. Ina hay unloading apparatus, the combination of a track extending interiorly and exteriorly of a barn, a carriage to travel upon said track, a pair of weighted pulleys, cables passing around said pulleys, guides forthe cables, one of said cables being connected to the carriage, a manually operable drum, the other of the cables being attached to the drum to be wound thereon, an additional cable connected to the weighted pulleys at one of its ends and'also attachedto the drum to wind thereon in an opposite direction with respect to the first named pulley, and means for manually rotating the drum in either direction to raise or lower the weighted pulleys and permit the carriage to travel in either direction upon the track.

2. In a hayunloading apparatus, an elevated track, a hay carriage to travel thereon, gravity means operatively connected to the carriage to move .the same in one direction on the track, manually operable means for elevating said gravity. means, a weighted pulley and a cable connecting the same to the carriage to move said carriage in an opposite direction with respect to its movement in the descent of said gravity means, and means for guiding the movement of said weighted pulley. V

' 3. In a hay unloading apparatus, an elevated track, a hay carriage to travel thereon, gravity movable means operatively connected to the carriage to move the same in one direction, manually operable means including a reversible drum and cables winde ing thereon from opposite directions, one of the cables being connected to said gravity the cables being connected to said gravity In testimonyvwhereof I hereunto ailix my means to lower the same and gravity movsignature in the presence of two Witnesses.
