Letters Patent No. 93,236, dated Aflgust 3, 1869.

`nvmRovr-.D HAY-ELEVATQR.

The Schedule referred to in these Letters. Patent and making part of the same.

-and l)elivcry-Apparatns57 and we do hereby declare that the following is a full and exact description .thereof, reference heilig had to the acco nip .ftnying drawings, v

and to the letters of reference marked ther-con.

Figure l represents a sidoI elevation of the skeleton or frame-work ot' a barn to which my apparatus has been attached;

Figure 2, a side. elevation of the windlass;

Figure 3, a front view of' the same;

Figure 4, a side elevation of the carriage and the devices by which' it is held in the desired position during the hoisting-operation; p

Figure `5 represents a front view of the same, in which the red outlines indicate how the carriage is 4released at the end of the hoisting-operation; and

Figure 6 is a plan or topview of thesaine, the red outlines 'indicating the same, as in the preceding figure. f

Corresponding letters referto corresponding parts in the several figures.

Our invention relates to portable hoisting-apparatus,

' which may be used for loadi'u g an d unloading hay, straw,

manure, 85e., or for excavating purposes, saidlapparatus beingso constructed as to deliver the raised substances It consists in the construction and arrangement of its several parts, as hereinafter more fully described.

To illustrate the operation of our apparatus,we have shown it in the drawings as attached to a barn.

A represents the wire rope or guy on which the cary riage is placed.` One end of it is secured, by means of a hook-and-eye bolt, to one end of the barn, under the roof,.and it is then extended along horizontally to the vother end of the barn, and, after it has been passed over the block a, which is suspended from the rafters, it is attached to the drum of a windlass and wound upon it until it has the required tension.

B represents the windlass, which may be of the most simpleconstruction, its sole object being-to hold the wire rope or guy at the necessary tension. It is secured under the block a to a cross-beam of the barn in any convenient manner.

C represent-s' the frameof the cam-inge, which may be made of sheet-metal, and must have theneccssary strength and dimensions to carry the different parts which are attached to it.

Near each end and in its upper portion it has grooved rollers, c c, which are placed between the sides of the frame and revolve on shafts, which are secured in the vtache-d therefrom-.-

frame in such a manner that they can be yeasily de These grooved rollers rest on the guy, and in order to keep thc carriage always in proper position on it a 'friction-roller, c', is place( in the frame between the groovcd rollers, and in such a manner that as the latter rests on the upper surface of the wire rope, its lower surface lies on top of the friction-roller. v

D represents the pulley', which revolves on a shatt secured to the sides of the frame of its carriage on one end of it, and in its lower portion. Over this the tackle passes by means of, which substances may be raised. p

E E represent two levers ot' the form clearly 'shown in fig, 5 of the drawings. They are hinged to lugs on the ii'am'e of the carriage in such a manner that their long curved arms extend downward vertically, and that that portion of the tackle to which the cone I, hereafter to be described, is attached, may move between them. The inner sides of these arms of the levers may be made concave where they are madeto moet, thus surrounding the tackle; r

"To the ends of the short arms, the latches Fare .hingcdgand they are acted o'n by the springs c e, which are fastened to the Sides of the frame, so as to throw them apart and bring the long arms together.

F F representA the latches or hooked levers, which are pivoted on each side of the frame to lugs in a horizontal position. One end of them is attached to the vin fig. 6, extend a short distance beyond the carriage and hook over the doublccatch. G represents the double catchwhich is clamped to the wire rope at the proper point, and in such a manner that, as the carriage is drawn up to it, the latches.

F will vhook over the catches and hold thc carriage in the proper posit-ion until they are again released from it by the action of the cone.

The catch consists of two plates of metal, the straight inner sides of which have longitudinal grooves, in which the wire rope lies, when theyare clamped to it. On the outer sides, on one end, theyare provided with hooks, as shown in fig. 6. 1 I

H represents the tackle, which is passed between the lsuspended arms of thelevers E over the pulley D of the carriage along in a horizontal direction to the i end of the barn over the pulley of the block h, which is suspended from the rafters, thence in an oblique 'direction to the'block h, which is attached to the side of the barn, and then down to the block h2, which is secured to the iioor of the barn.

I represents the cone, which is attached to that end of the tackle which hangs from the pulley of the carriage, and t which the weight to be raised is attached.`

i It slips over the tackle, ,and may be secured to it at any to the endV of a rope, k, said rope passing over the block It, which-is suspended from the rafters directly above the guy and backof the double catch and carriage, and thence to that end of, the carriage nearest to the catclnwhen it is secured to said carriage in any convenient manner.

The weight must be heavy enough to draw the carriage back to the catch when the load has been deposited. I

The operation is as follows:

A load of hay or grain is drawn directly under the carriage di' the apparatus. The cone is secured to the tackle, so that it will release the carriage when the hay or grain has been raised to the necessary height. The hay is now taken up by means of a fork attached to the end of the tackle, which hangs down from the carriage and raised by employing the necessary power at the other end of the tackle until the cone is drawni between the levers E, separating them, and thereby releasing the latches from the double catch.

The carriage will at once be drawn along the guy 'up to the point where it is desired to deposit the hay,

'its latches becolne engaged thereto by the action of the counterweight.

When it is desired to remove the apparatus from one place to another7 the tackle and its blocks can be taken down first, then the guy andwindlass removed, and lastly the carriage and counterweight.

Some of the advantages of this apparatus consist in its peculiar construction, by .which we are enabled to transport it from place to place with ease and rig it up at a small expense, and that it will deliver raised weights at any given point.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, isl l. The doublecatch G, substantially as and for the purpose described.

A2. The combination of' the cone I, tackle H, levers E, springs e, .latches F, and` double catch G, substantially as and for the purpose set forth.

In testimony whereof, we have signed our names toA these specifications in the presence of two subscribing witnesses.
