JOHN H. BURKHOLDER, OF ASHLAND, OHIO.

HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 545,943, dated September 10, 1895.

Application filed March 4, 1895 To all whom it may concern:

Be it known that I, J OHN H. BURKHOLDER, a citizen of the United States, and a resident of Ashland, county of Ashland, State of Ohio, have invented a new and usefnllmprovement in Hay-Carriers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in hay-carriers, the object of which is to provide means by which the carrier may remain locked in connection with the track while the load is being elevated and at a desired instant be automatically or manually unlocked or disengage the carrier-frame from the stopblock to drop the brake upon the hoisting rope to hold the rope and load against reverse movement while it is being inoved on the track to a desired place of deposit.

With these objects in view my invention relates to certain features of construction and combination of parts, as will be hereinafter described and claimed.

Figure 1 of the accompanying drawings is a view in perspective of a haycarrier illustrating my invention. Fig. 2 is a vertical section showing the carrier locked to the stop-block. Fig. 3 is a side View, partly sectional, showing the carrier as disengaged from the stop-block and the parts dropped down to grasp the hoisting-rope to hold the load at a point of desired elevation. Fig. 4 is a perspective of the lower part of the carrier-frame. Fig. 5 is a similar view of the drop-frame that carries the pulley and the rope grip or brake. Fig. 6 illustrates in plan a swivel connection of parts of the carrier-frame. Fig. 7 represents a detached part of the swivel connection.

A denotes the track; B, the upper portion of the carrier-frame, in which are supported the carrier-wheels C and swivel-ring D, on which is supported a corresponding ring E. The ring D is made in two parts provided-with perforated lugs, said parts being secured to gether by bolts which pass through said lugs and also secure the ring D to the frame 13. The ring E, which is within the ring D and is formed to rest thereon, is made in two parts, each of which is made integral with a side part of the frame F. A swivel connection is thus formed by which the lower part of-- said Serial No. 540,424. (No model.)

frame F may be turned to carry the running portion of thehoisting-rope G to either side and to allow the carrier to be operated either way on the track. The lower portion of the frame F is formed substantially as shown in Fig. 4 and will be referred to as the fixed portion ofthe frame. At the top portions ofthe frame F are provided parallel bars a, to which is pivotally secured a lock-block I-l, having prongs b and b, that are adapted to engage the prongs c and c of the stop'block .T, which is secured to the track A. The drop-frame K is formed substantially as shown in Fig. 5, and forms a support for the movable part cl of the brake Z,- the fixed part e forming a part of the frame F.

To connect the frame K with the frame F the upper end portionsfof frame K are inserted in the loops or sockets g, formed on the upper part of frame F, and the lower end portions h are set in recessesj, formed on the lower part of frame F. The upper part (Z of the brake z is carried by frame K and is held in position Within the frame F by a bolt It, passed through the side parts of the frame K and extending through openings in the frame F. (See Figs. 1 and 5.) The pulleyLis placed between the circular portions of the frame F and is journaled on a cross-bolt, as m, supported in the drop-frame K. A link, as M, connecting the bolt m and frame K with the upper end portion of the pronged block H, is provided, as shown in Figs. 1, 2, and 8. The lower end portion of the link M is bifurcated. The prongs pass down on each side of the pulley L and are pivotally secured on the bolt m, and the upper end of the link passes up between the downwardly-projected prongs n of the block H, that are pivotally secured to the parallel bars a, and is pivotally secured to said block at a point above its pivotal connection with the frame F.

N denotes a lock-lever, that is pivotally se cured to the frame F on bolt 0. The inner end of said lock-lever is bifurcated, and to the inner ends of the prongs p is pivotally secured a clevis-like trip P. The hoisting-rope G is secured by one of its ends to the clevis q, sup ported in the drop-frame K. The other end is passed about the pulley R, up and over pulley L, and out between the clamping-jaws cl and e of the brake.

5 the parts in locked position.

[0 from engagement with the lock-block II, when the frame K, with the loaded fork, will sink until arrested by the upper part (1 of the brake closing on the rope G. As the frame K sinks, the block H, with which said frame is connected by the link M, is pulled over from connection with the stop-block J to the position shown in Fig. 3, the prong 12 passing between the prongsp of the lever N, and with the parts in such position the fork with the load will be held in an elevated position until the carrier has been drawn over the track to a place of deposit, when the load may be dropped in the usual way; or when desired the lock-lever N may be operated to release the drop-frame at any desired point of elevation by drawing on the cord T, which will operate the lock in a manner similar to that hereinbefore described, after which the carrier may be drawn back to the place of beginning and locked in 0 engagement with the stop-block J. The prong b, engaging the prong c of the stop-block, will raise the locking-block into position shown in Fig. 2. The weight of the trip P, having drawn the locking-lever N down into position, holds The rocking of the locking-block H on its pivotal connection will by its linked connection with the frame K raise it to its elevated position, as shown in Figs. 1 and 2.

'When the invention is used in connection with a hay-sling instead of a fork, two pulleys, as R, will be placed on the rope G, to which the ends of the sling will be connected in the usual way.

Having thus fully described the nature and object of my invention, what I claim is 1. The combination, with a track, A, carrier, B, and frame, F, of the stop block, J, having downwardly projected prongs, c 0',

secured to the track, a locking block, H, having prongs, b b, pivotally secured to the frame, F, a lock lever, N, adapted to hold the block, H, in engagement with the block, J, a drop frame, K, a link, M, connecting the block,

H, with frame, K, a brake shoe, (1, carried by the frame, K, and a rope, G, substantially as described and for the purposes set forth.

2. The combination, with a track and a stop block, of a carrier having a non-vertically movable frame, another frame adapted to move vertically thereon, devices adapted to lock said latter frame in connection with said stop block, a brake, a draft rope, a pulley journaled in said Vertically movable frame, and devices for releasing the last mentioned frame from said stop block, whereby said brake is closed and the draft rope is made fast to the carrier, substantially as and for the purposes set forth.

3. In a hay carrier, a fixed and a movable frame, devices for locking said movable frame in position, and devices for releasing it, a pulley mounted in said movable frame, a draft rope passed over said pulley, a rope brake, one part of which is carried by the fixed frame, the other part being carried by said movable frame, whereby, when the latter frame is released from the locking devices, it will sink a distance, so as to actuate the brake to grasp the draft rope, substantially as and for the purposes described.

4. In a hay carrier, the combination with two parts of a frame, one of which is fixed and the other is movable, of a locking block, pivotally connected with said fixed part of the frame, and a link connecting said looking block with said movable frame, whereby the latter, with the parts supported thereon, may be raised and held in its elevated position by the engagement of said locking block with a stop block, substantially as and for the purposes described.

5. The combination with a track, of a carrier, having a relatively fixed frame depending from said track, and a frame adapted to move vertically on said fixed frame, devices for raising and locking said movable frame in its elevated position, a rope brake made in two parts, one of which is carried by the fixed frame and the other by the movable frame, a pulley journaled in the movable frame, a draft cord passed over said pulley, a tripping device adapted to be raised by said draft cord and to release said movable frame, whereby the latter is allowed to sink so that the draft rope is grasped by the said brake, substantially as set forth for the purposes specified.

In testimony whereof I have hereunto set my hand this 26th day of February, A. D. 1895.

JOHN H. BURKIIOLDER.
