HAY-CARRIER.

Specification of Letters Patent.

Patented July 25, 1905.

Application led March 13, 1905. Serial No. 249,759.

To @ZZ whom, it may concern:

Be it known that I, JOHN H. BURKHOLDER, a citizen of the United States, residing in Ottawa, in the county of Lasalle and State of Illinois, have invented a new and useful Improvement in Hay-Carriers, of which the following' is a speciiication.

This invention relates to the construction of hay-carriers; and its main object is to provide such carriers with means whereby the turn-table of the carrier will be locked against swiveling except when the fork-pulley is released by the trip-block. As it is desirable to swivel or reverse the carrier only when it is locked in the trip-block, it will be seen that my invention is adapted to prevent all unnecessary and undesirable turning while the load is @n wat@ to its destination.

The invention consists in a carrier having a turn-table which is locked against swiveling while the carrier is loaded and is also adapted to be released from thelock by the trip block or device.

It also consists in the novel combinations of parts and devices and novel constructions of parts and devices hereinafter described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of the invention, and Figs. 2 and 3 are sections upon the lines 2 2 of Fig. 1, Fig'.

2 showing the carrier in the position given in Fig. 1 and Fig. 3 showing the position after the carrier has been engaged by the tripblocli. Fig. 4is a horizontal section, and Fig. 5 is a section at right angles to that given in Fig. 2.

In the drawings, 6 represents the carriertrack, and 7 theordinary construction of tripblock.

8 represents the frame in which the supporting-wheels 9 are journaled and forming the car or carriage of the carrier. In the lower part of this frame a circular groove IO is formed, in which the rim 11 of the turn-table is supported in the usual manner. Depending from the rim is the main body 12 of the turn-table, in which are pivoted the rope-pulleys 13 and also the grappling-dogs 14. The drop-lock is shown at 15 with the usual overhanging arms 16 for engaging the trip-block. The lock is adapted to move down between the upper arms of the dogs, as plainly seen at Fig. 2. The drop -lock also has wings 17 moving' between guards or ways 19 on the inside of the frame 8 and is movable vertically in such ways in the usual manner. The guards hold the drop-lock from turning with the turn-table, as will be understood.

In order to lock the turn-table against swiveling, I cut out the rim of the turn-table upon opposite sides, as shown at 2O in Fig. 4, these openings being so located that the wings of the drop-lock will enter them when the droplock assumes its acting position. The openings in the turn-table rim are larger, preferably, than the wings in order to insure without fail the entrance of the wings into them when the drop-lock is allowed to fall into position between the grappling-dogs. If necessary, the wings are made somewhat longer than heretofore to enable them to move down into the rim and effect the locking of the turntable, as will be understood from Fig'. 2. The drop-lock effects this locking of the turntable whenever the forli-pulley 24 is raised so as to operate the dogs, and it releases the lock whenever it is raised by the trip-block. It is shown thus raised at Fig. 3, and while raised the turn-table can be turned in either direction and to any extent desired; but the locking is resumed, ofcourse, whenever the drop-lock is permitted to fall to its lowest position by the entrance of the fork-pulley into the bellmouth of the turn-table and the spreading of the locking ends of the grappling-dogs which then takes place.

The dog's are adapted to support the forkpulley by entering under the rim of the pulley-sheave in the manner set forth in my pending application, Serial No. 237,488, filed December 19, 1904, and, as will be noticed, the arms 21, whereby they are swung by the forlipulley, are disconnected from each other instead of being united, as in the customary construction. In order to permit their independence of each other, I provide two stops for each dog', one at 22 and one at 23, one serving to limit the swinging of the dog in one direction and the other in the opposite direction.

I claim-- 1. In a hay-carrier, the combination of the turn-table and the drop-lock, the turn-table having openings in its rim adapted to be entered by the drop-lock.

2. In a hay-carrier, the combination of a swiveling turn-table, a drop-lock adapted to lock the turn-table, and grappling-dogs controlling the position of the drop-lock.

3. The combination in a hay-carrier appaswiveling turn-table, the fork-pulley and the drop-look, of grappling-dogs mounted on separate pivots in the turntable and each independent of the other, euch dog being also provided with Stops limiting' its movements in both directions.
