JOHN FARRELL, OF HUNTSVILLE, NEYV JERSEY.

HAY-CARRIER.

SPECIFICATION forming part of Letters Fatent No. 404,525, dated June 4, 1889.

Application filed August 7, 1388. $erial No. 282,153. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN FARRELL, of Huntsville, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Hay Carriers, of which the followingis a specification.

This invention relates to a traveling carriage for conveying hay.

The invention consists in certain details of construction and combination of parts, which will be fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation, with parts broken away, of my improved track and traveling carriage for conveying hay. Fig. 2 is a vertical longitudinal section of the same, showing the locking-lever and fork in lowered position. Fig. 3 is a top view of the carriage. Fig. 4. is a detail side'view of the latch.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the supporting-track on which the carriage is supported and runs, the track made of metal of inverted-U shape, and'provided with longitudinal slots a, for attaching the suspending ropes or hangers X, by which the track is suspended from the rafters of the barn. At proper intervals the track A is provided with filling-blocks A of wood or other suitable material, for stiffening the track; or the entire track may be filled with stiffening material.

The carriage D is made of a cast or mallea ble metal frame I), which is provided at its upper part with bearings for flanged rollers Z), by which the carriage is supported and runs on the track A. To the lower end of the frame I) is applied aswiveled lower movable part B" of the carriage-frame, the swiveled connection being made in the nature of a turn-table. As the lower part B is guided by a flanged guide-ring b in an exterior guidering b of the top frame I), the upper part of the carriage is made of two longitudinal halves, which are united by bolts c, passing through ears 6' of the frame-sections, as shown in Figs. 1 and 2. The lower swiveled part B has two forked ends B and 15", so as to support; at one end B the f ulcrumed lockinglever O and at the other end B the guidepulley D for the suspending-rope D of the fork, which rope is passed over a pulley E, from the pulley-frame of which the fork-head is suspended in the usual manner.

The locking-lever O is provided with a tubular or grooved arm 0, which is curved on a segmental line of about the same radius as the pulley E, from which the fork-head is suspended. WVhen grooved, as shown in the drawings, it is provided at its lower end with a curved band or collar 0 and at its upper endthat is, near the pivot-it is provided with a collar 0 One end of the rope D is passed through the collar C through the groove in the under side of the arm C, and

through the collar 0 and is then knotted above saidcollar C or otherwise provided with an enlargement, whereby the rope is held firmly and securelyin said locking-lever.

To a transverse pivot of the lower yokeshaped part B of the frame is pivoted a lock in g-latch F, which is provided at one side with a heel F, that engages a stop f at one end of the arc-shaped end of the locking-lever O, or the inclined part F of said locking-lever, when the fork is to be locked in raised posi-' tion, as shown in Fig. 1. The latch is also provided with a central socket g, that is engaged by a fixed stop g, attached to the track or a filling-block of the same, as shown in Figs. 1 and 2, wherever the latch is to be disengaged from the locking-lever, so that the fork can be lowered.

The top edges of the socket g are beveled from two opposite points in the longitudinal plane of the socket downward toward two diametrically-opposite points in a transverse plane of the socket, so that the top edges of the socket are V-shaped, thus permitting the stop g to enter into the socket even when the latch strikes the stop at an angle.

The latch is pivoted centrally to the swiveled frame of the lower movable part B, so as to interfere as little as possible with the ready turning of the swiveled part and exert thereby no injurious strains 011 the same, while being reliably acted upon by the stop when arriving at the same. A transverse stop or bridge f of the movable part B preventsthe latch swingingtoo far toward the roller 1), and thus prevents it from passing the stop. The fork, after having been loaded with hay, is raised up to the carriage by pulling the rope D in the direction of the arrow 00', Fig. 2, the rope-pulley E runs upon the arm 0 of the locking-lever, said arm passing through the frame of the pulley E, and then the said rope D swings the locking-lever into the position shown in Fig. 1. lVhen the locking-lever is raised, the latch F is free to drop by its own weight; but as the entire carriage is drawn in the direction of the arrow :13 by the rope I) the left-hand side of the socket g is pressed against the left-hand side of the stop g, which assists in swinging the latch down in a position for locking the lockingdever in place. The pulley E of the fork is now supported on the arm C of the locking-lever, and said locking-lever is locked in place by the latch F, thus preventing the load of hay on the fork from descending, and the fork which is now securely supported from the carriage travels with said carriage in the direction of the arrow 11:. \Vhen the carriage arrives at the point where the hay is to be discharged, the fork is emptied in the usual manner by pulling on the fork-rope, (not shown,) the fork being still suspended from the raised lockiug lever C in the manner shown in Fig. 1.. By means of said fork-rope the carriage is then moved in the inverse direction of the arrow 0: until it arrives at the stop g, which, en gaging the socket g, swings the latch F in the direction of the arrow 0:, Fig. 1, and into the position shown in Fig. 2, whereby the lockinglcver is released and can swing from the position shown in Fig. 1 into the position shown in Fig. 2 until it is stopped by the stop f on the locking-lever engaging the heel F on the latch F. As soon as the locking-lever swings down the fork-pulley E runs down the same, and as the rope I) is slackeued the fork descends, ready to take another load. The latch F produces the reliable locking of the locking-lever owing to its central position in the turn-table of the movable part of the frame, and to its being heavier at one side, so as to be readily tilted when released from the fixed stop g. hen the stop g is in the socket g, the lower part B of the carriage D can be turned axially and the apparatus work in an opposite direction, the stop and socket preventing the carriage from running on the rail while being thus reversed.

All the parts (locking-lever, latch, and supporting-frame) are made of cast or malleable iron, and are made as light as possible consistent with strength, and perform their fu netions of locking and unlocking in a reliable manner without interfering with the ready swinging of the lower movable part of the frame according to the direction in which the fork is moved in discharging its load of hay.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a hay carrier, the combination of a carriage having a lower swiveled portion, a latch pivoted to said swiveled portion at the center of the same, and a locking-lever provided with an arc-shaped upper part having a stop at one end and an inclined port-ion at the other end, and with an arnrat the lower end, substantially as set forth.

2. The combination, in a hay-carrier, with a track, of a carriage provided with a lower swiveled part, a latch pivoted centrally to said swiveled part and provided with a socket, a fixed stop on the track for engaging said socket, a fulcrumed locking-lever pivoted to the lower movable part of the carriage and provided with an arc-shaped upper part havin g a stop at one end and an inclined portion at the other end, and a guide-pulley for the fork-supporting rope, substantially as set forth.

3. The combination, in a hay-carrier, of a traveling carriage having a lower swiveled part provided with a fixed transverse stop, a latch pivoted centrally to said swiveled part and provided with a socket and with a stop at one end, a locking-lever provided with an arc-shaped upper part and a stop, a rope attached to the lockinglever, a traveling guidepulley for the fork, and a pulley at .the opposite end of the lower swiveled part, substantially as set forth.

ft. The combination, in a hay-carrier, of a carriage having a lower swiveled part, a latch pivoted centrally to said swiveled lower part and provided in its top with a socket having its top edges inclined from two diametrically-opposite points in the longitudinal plane of the latch to two diametrically-opposite points on the transverse line of the latch, a track on which the carriage runs, a stop on said track, which stop can enter the socket on the latch, and a pivoted locking-lever that can be engaged and locked in place by the above-mentioned latch, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

.TOIIN FARRELL.
