HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 271,218, dated January 30, 1883,

Application filed October 28, 1882. (No model.)

T 0 all whom ti may concern Be it known that I, ELI A. BYERS, a citizen of the United States, residing at Birmingham, in thecounty of Van Buren and State of Iowa, have invented certain new and useful Improvements in Hay-Elevators; and I do hereby declare the following to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and'use the same.

My invention relates to that class of hayloaders which are adapted to be swung from one side to the other, or entirely around the supporting-points when desired.

The nature of my invention will more fully appear from the subjoined description and the accompanying drawings, in which Figure 1 represents a perspective view of my device, showing all the parts in position; Fig.2, a top plan view of the guy-rope support; Fig. 3, a side elevation of lover I provided with a clevis, and Fig. 4 a detail view of the lever and clevis.

A represents the mast; B, the crane; O, the brace-arm; D, the brace-rod; E, the elevating rope; F, the drag or sub-elevating rope; G, the swing-rope; H, the check or stop; I, thelever; K, the hay-fork; L, the guy-ropes, and M the crane-rope.

The mast A is preferably between twentyfive and thirty feet high, and its sides are formed of flat pine scantling two inches wide and four inches thick, banded at each end, sprung apart at the center from six to eight inches, and cross-pieces about every three feet for bracing the mast-beams. The bottom of the mast is provided with a bearing, a, which is stepped in a plate, A, supported by any suitable means. The upper end is also provided with a pivot, to, which passes through a guy-rope support, A This support is pro vided with arms o to which the guy-ropes are attached.

Below sunort A is a rin A havin anarm, a to which the upper end of the iron brace-rod is attached. This rod D passes downwardly and over the brace-arm, and is attached to a ring and hook similar to ring and hook A a upon the upper end of the mast.

About ten feet from the top of the mast is the brace-arm 0, attached to said mast by means of bolts which pass through a foot, 0, on brace-arm 0. Upon the outer end of this arm is a groove or eye, 0, for the brace-rod D.

The crane Bis formed of two pieces of scantling, joined together at their outer ends, splayed at their inner ends, and provided- With crosspieces I) b for holding the inner ends apart. The said inner ends embrace the mast, and are pivoted to the elbows c of the bracearm C at b b. The outer end is provided with a pulley, m to which the cranerope M is secured. This rope passes over a pulley, m, fixed near the top of the mast, and is prevented from slipping when the crane is fixed in position by a cleat, m, attached near the lower end of the mast.

The under side of thecran'e is provided with two pulleys, c 0, over which theelevating-rope E passes. This rope is preferably endlessthat is to say, the ends are spliced together after they have been passed over pulleys e e and through eyes 6 and it, placed respectively on drag-rope F and hay-fork K. The object in making this rope double is to prevent the fork from twisting when lifted, and also to equalize the strain upon the difi'erent strands which make up the rope. When the fork islifted by pulling upon the drag-rope F the elevatingrope E adjusts itself in eyes 0 7c and pulleys c and o. By these means the weight is also suspended between the two pulleys, and is pre vented from gyrating or twisting in such a manner as to interfere with the lift-rope and the proper distribution of the load. To the eye 6 is also attached the drag or sub elevating rope F and the swing-rope G, which passes over pulleys i i on lever I, and are attached to the hook it on the whiffletree N.

The swing-rope G is provided with a check or block, H, having a set-screw or other device for fixing it to the rope, for a purpose that will hereinafter be described.

The lever I is attached to the mast by means of a olevis, P, which is provided with nuts, so that the lever can be changed from one side to the other of the mast; or it may be passed through the mast, as shown in Fig. 1. It is obvious that many other devices could be used for that purpose. Upon the short arm of the lever is a pulley, i, over which the drag-rope F passes. This pulley is preferably provided original position.

with a central stock, which fits over the end of the lever and holds the pulley at right angles to the length of the lever, so that when the arm is changed the pulley will always be in position to receivethe drag-rope. Thelon g arm of lever I is provided with an eye, t, which may also have a small pulley for the swing-rope G. The object of this arm is to check the movement of the swing and drag ropes, so that when the load has been lifted a sufficient distance the crane will swing around to any desired point. This is accomplished by settingcheckHatapredetermined point. The horse pullingin the Whiffletree causes the ropes F and G to pass over pulleys it" and draw the elevating-rope E upwardly. When the check H strikes the eye or pulley t" the elevating movement is stopped and the crane begins to turn upon its bearings. When the load has been dumped the crane is turned back to its If desired, a second check, H, may be placed on swing-rope G at a suitable point between the whiffletree and the lever, so as to regulate the drop of the fork. This check may also be useful to turn the crane back to its original position.

If desired, the plate A may have its upper face inclined, so that when the mast is turned thebase will move up the incline, and when the power is removed it will move down the incline and assume its original position.

If necessary, small rollers may be placed upon the bottom of the mast, so that it wil turn with greater ease.

' 2. Ina hay-elevator, a pivoted mast having a lever provided at one end with 'a pulley and at the other with an eye or pulley, for the purpose set forth.

. 3. In a hay-elevator, a pivoted mast having a reversible lever provided with a pulley at one end and an eye or pulley at the other, for the purpose set forth.

4. The combination, substantially as described, of a revolving mast, a crane, an elevatin g-rope having a hay-fork suspended therefrom, a drag-rope passing over one end of a lever on the mast, a swing-rope passing over the opposite end of the lever and-having acheck or stop, said lever on the mast and provided with pulleys for the drag and swing ropes, and a whiffletree for the drag and swing rope, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ELI A. BYERS.
