lTO WHOM IT AMAY GONCERN: A l

Beit known that I, JOHN Wasrovun, of Taylor Post-Oiiice, vin the countyf of Ogle, vand State of Illinois, t have invented anew and useful Improvementin lLlevators;` and do declare that the following 'is a true and i accurate description' thereof, reference being had to the accompanying drawings, and to-the letters of reference marked thereon, and being a part o'f this specification, in'which like letters indicatelike parts in each ligure.

'Figure 1 is a top view.

Figure 2 isa side elevation,

Figure 3 is 4'a front view'of the extension-arm.

Figure 4 is a bottom view of the same.

The nature of my invention consists in constructing an elevator, for the purposeof raising a wagon-box or hay-rack filled with grain, hay, straw, or other heavy material, in the field, for building stacks equally as well' asn theharn, for the purpose of raising hay to the level ofthe bays', and is'easily moved from place to,plaee, being provided with adjustable wheels for that purpose. l y

To construct my apparatus, I build a frame, A, surmounted by the platform B, upon which I erect the standards C, at the top of which I place the sheaves D. i Y

'E are wside-timbers, secured to the standards C, in the front of whiclris journalled the shaft F, at the'centre of which is secured the ratchet-drum G, held-in position by the pawl H, and Vsecured by the stop I. i. Y

J are wheels, revolving upon proper axles ,in the pedestalsiK pivoted to the-,rear ends ofthe side-timbers E'. These pedestals are secured in an upright position by means of-the pinsI L wheni'tis desired .tomove the. apparatus.

M are horizontal rods, provided with guides, N,'sliding in grooves in the standards C.. l

O are guide-pulleys at the sides of the two rear standards. I. Y A, 4

P are elevating-ropes, secured lto the horizontal rods M, and running over the sheaves D, the two rearA ones also under the guide-pulleys '0, and wound upon the Ashaft F by unwinding the drag-rope Q'from the ldrum G, and to which the team is attached by means of a'proper hook orother device. l R are transverse extensionearms, which are intended to form .the base of a hay-rack, or may be secured to a, wagon-box by proper hooks, and are so constructed that by means ofthecrossed cords running'over suitable pulleys, and secured alternately to the inner ends ofthe extensionsarins R1 and Rz, when eitherof them Vis drawn out or retired, the corresponding one is caused togadvanceor retire at the same time.

To operate myapparatus, we will suppose it to be placed yalongside of a hay-stack in course of erection.

"The wagon, represented in the drawings by the block of woods, is surmounted by a hay-rack, resting upon the extension-arms It, is drawn-upon the platform VB, the horsesstraddling the drum G as they pass o, stopping immediately after passing off, which will bring thedouble-tree's .directly overthe drum. The double-trees are then detached from Athe tongue of the wagon, and attached 'to the hook on-the drag-rope l The sliding arms R1 and R2 are then drawn out so as to project over therhorizontal bars M The team is then driven' ahead. As the mg-rope unwinds from the drum G, the elevating-ropes P are wound upon the shaft F, and the rack, with its load, is elevated to the desired height, the Apawl H retainingthe drum G in its position, and, if necessary, the stop I may be used to insure greater safety. Y 4

After the hay is unloaded from the rack to the topof the stack, hy throwing the pawl H out of gear, the rack willl he lowered on to thewagon, by its own weight, asithe team is backed up; the drag-rope Q being re-wound upon the drum G, ready for elevating the next load. y l I This apparatus serves equally as well for elevating hay or straw-in the barn, being placed on thejloor between the bays. To move lit from place to place, the rear end is slightly elevated, bringing the pedestals K to a vertical position, where they are secured by the pins L. The front end of the'machinemay be'seeured t0 the rear axle of a wagon, or rest upon .the rear end of the box, when the whole may be moved with ease. V

What I claim as my invention, andpdesire to secure by Letters Patent, is i 1. The extension-arms.RI and R2, in connection with any suitable hay-rack or wagon-box, when used for the purposes herein described and set forth. l

2. The combination and arrangement of the frame A, platform B, standards C, provided with sheaves D and guide-pulleys O, the side-timbers E, pedestal K, wheels J and pins L, the shaft F, drum G, pawl H, stop I, horizontal bars M, guides N, elevator-ropes P, and drag-ropes Q, in connection with the extension-arms Rl and R2, when constructed, arranged, and-operating substantially as described, and for the purposes herein set forth.
