HAY-SLING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 357,964, dated February 15, 1887.

Application filed November 3, 1886. Serial No. 217,898.

To all whom it may concern.-

Be it known that I, PHILIP A. MYERs, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Improvement in Hay-Sling Attachments for Hay- Oarriers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to hay-carriers, and my object is to combine with an ordinary carrier adapted to be used with a fork or equivalent device an attachment for connection with a sling, so that the user may avail himself either of a fork or sling in connection with thejsame carrier.

I have shown the attachment in connection with the form of doublelock reversible carrier in Letters Patent of the United States granted to me on the 4th day of November, 1884, but do not limit myself to the combination, as the attachment, without material change, may be applied to other carriers.

In the accompanying drawings, Figure 1 represents a section taken longitudinally of the carrier, with the operating parts in the position assumed by them when the load is down. Fig. 2 is a similar view with the load raised. Fig.

'3 is atransverse section on line mat of Fig. 2.

The sling attachment is supported upon a frame composed of two side pieces, A A, a convenient shape of which is shown in Fig. l; but the shape may be varied, provided that it is adapted to be attached to the carrier to support the working parts herein described. The two sides are held together and the frame is completed by the bolts which hold the frame to the carrienand the working parts to the frame. Between the sides at the angle of the longer arms of the side pieces and the bottom bars is located the pulley B, which turns on a bolt, 12, passing through thesides and wheel; but on the other angle of the frame, opposite the shorter arms, on the bolt 0, passi ng through the frame, is pivoted the dog 0, which stops the rope and sustains the load after it has been raised. In order to apply this frame to the carrier shown in my said Letters Patent, the wheels (shown in dotted lines and marked in the drawings D D) are removed, and the bolts d e, which serve to hold the wheels in the frame, serve also to hold the frame of the sling (No model.)

attachment to the frame of the carrier by passing through holes in the ends of the arms of the frame after those holes have been brought to register with the holes of the pulley-bolt in 5 the carrier-frame. The arms of the frame are arranged to fit outside of the carrier-frame, and on the bolt 6, within the frame, in the position formerly occupied by the sheave, is placed a lever, F. Theinner endofthislever is formed with a head, wedge-shaped on its upper side and having shoulders 1 1. This construction fits it to act in the place of the pulley-block in the ordinary carrierthat is to say, when the end'of the lever F is forced up, it spreads the trip-levers or catches J, and when the shoulders l 1 have passed up above the corresponding shoulders on the trip-levers the springs 1, Fig. 3, of the levers force them inand catch and retain the end of the lever F. The under side of the lever Fis channeled longitudinally, and in the end underneath is pivoted the upper end of the depending arm G. This arm carries on its lower end the loop or bail g, which is substantially at right angles to the arm, and is suspended in substantially a horizontal position below the pulley, thus forming a guide for the rope and directing the bundlepulleys thereto, so that when a bundle is drawn up it raises the bail, and thus pushes up the wedged end of the lever F and causes it to catch into the trip-levers, whereby it is held in elevated position.

The dog heretofore described is slotted, and the depending arm passes through it freely.

The wedge end of the lever F has also the same effect as the hoisting-pulley in spreading the trip-levers to release the carriers from the knocker or stop S on the track after the bundle is raised, and allows it to move in the 0 same manner on the track to its proper position over the mow. This lever F is released and drops when the carrier returns to the stop or kno'clzer, and allows the trip-levers to engage with the notches in the sides of the 5 knocker on the return of the carrier, in the same manner as described in my aforesaid patent.

The suspension of the load after it is raised is effected by means of a dog, heretofore described. The outer end is armed with teeth formed to fit against the rope as it passes over the pulley. To bear against the rope, it drops into position shown in Fig. 2. It is held up out of contact with the rope when the lever F and loop are down by means of a spur, H, on the pivoted end of the level-F, which extends downwardly within and slightly past the end of the corresponding spur, h, on the pivoted end of the dog. These parts are so arranged that when, as aforesaid, the arm and loop are down, as they normally are when not pushed up by the load, the spur on the lever F holds back the spur on the dog, and thus holds the dog out of contact with the rope; but when the lever F is forced up by the rising load of the bundle the spur H is moved inwardly and the dog is allowed to drop againsttherope,and the arrangement is such that the backward strain upon the rope tightens the grip of the dog, and thus the load is held securely. As the lever F and arm depending-therefrom are held up by the trip-levers while the carrier is conveying the load to the mow and returning, the dog is allowed full and free action upon the rope, and, as above explained, the releasing takes place upon the arrest of the carrier upon its return. To insure the prompt releasing of the lever F when the trip-levers are spread, a spring, f, is applied to said lever, tending to force it downward, this action being secured by the spring coming in contact with the knocker or stop S. The loop is mainly for the purpose of insuring contact with the bundle-pulleys with some part of the rising load, and need not be in the shape shown. It is sufficient that the lower end of this arm should be provided with convenient means for effecting contact with the rising load. The mode of gathering the bundle in the sling-pulley shown is one in common use, and is notherein claimed. Any other form of sling may be used in the place of that shown. The downward movement of the arm is limited by the spurs on the lever and dog.

The apparatus above described does not require any disarrangenient of the carrier or any change in the stop or trip mechanism of the carrier or way, and it may be applied to the carrier quickly and easily. Further, it may be adapted to other carriers without material.

change, as it may be attached to the carrierframe otherwise than as above explained.

It is essential only that the carrier have some mechanism to perform the function of the trip-levers and be operated by the rising load, and have also equivalent of the knocker or stop on the track thereof, on which mechanism the lever F may operate, as explained.

I claim as my invention 1. In combination with a hay-carrier having mechanism for catching and retaining the load, adapted to be releasedby a mechanism on the track in connection with a stop, a frame supporting a pulley, B, a dog, 0, on the frame adapted to bear on the rope upon the pulley, a lever, F, connected to a depending arm, G, arranged to be lifted by the rising load and adapted to be operated in connection with the catches onthe carrier and stop or trip mechani'sm on the track, and mechanism connected with the lever for holding the dog out of contact with the ropewhen the load is connected to the carrier, all substantially as described.

2. In combination with the frame of a hayearrier having trip-levers J, adapted to a knocker or stop, S, on the track, a lever, F, pivoted upon the frame adapted to engage with the trip-levers and to release them from the stop, an arm depending from said lever adapted to be lifted by the rising load, a sling and pulley, as B, and a dog mechanism controlled by the lever F, substantially as described.

3. In combination with the frame of a haycarrier having trip-levers J, adapted to a knocker or stop. S, on thetrack, a lever, F, having a spur, H, pivoted upon the frame, adapted to engage with the trip-levers and to release them from the stop, an arm depending from said lever adapted to be lifted by the rising load, a sling and pulley, as B, and a dog, 0, having a spur, H, substantially as described.

4. In combination with the frame of a hay carrier having trip-levers J, adapted to stop mechanism on the track, a lever, F, fitted to engage with the trip-levers, a deg, C, with mechanism whereby they are controlled by the lever F, and a depending arm, G, connected to the levers F, having a loop or bail, 9, adapted to the loop and sling, all substantially as described.

5. In combination with a frame of a hay carrier provided with mechanism adapted to engage with the stop mechanism on a track and a catch and retaining mechanism for hoisting the load, a supplemental frame, as A, adapted to be connected to the frame of the hay-carrier in the place of its ordinary pulleys, a lever having a depending arm pivoted on said connecting-frames and having a depending arm adapted to be operated by the rising load, and the dog controlled by said lever, substantially as described.

6. In combination with the frame of a haycarrier of the class described, a supplemental frame, A A, connected to the hay-carrier frame by bolts d e, a lever, F, pivoted on the bolt 6 and provided with a spur, H, and dog O, pivoted on the supplemental frame having a spur, h, and depending arm G, pivoted on the lever F, provided with a bail or loop, 5 and pulley B, pivoted upon the supplemental frame, and a suitable sling, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
