HAY-CARRI ER.

SPECIFICATION forming part of Letters Patent No. 488,330, dated December 20, 1892.

' Application tiled July l, 1892. Serial No, 43 8,726. (No model.)

To @ZZ whom t may concern:

Be it known that I, HENRY H. DURR, of

Utica,in the county of Oneida and State of New York, have invented certain i new and 5 useful Improvements in Hay-Carriers; and I do hereby declare that the following is a full,

clear, and exact description ot' the invention,

which will enable others skilled in the art to which it appertains to make and use the same, lo reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

My invention relates to an improvement in hay carriers and tracks therefor.

In the drawings which accompany and to which this specication refers, Figure l shows in side elevation the improved car or carrier in 'connection with a section of the track on zo which it runs, a track suspending hook and a trip block. Fig. 2 shows a cross section of the rail and edge or end views of the carrier, suspending hook and trip block. Fig. 3 shows a side view of the frame of the carrier. Fig. 4 shows an edge View of the same. Fig. 5 shows the carrier in section with the working parts in open position. Fig. 6 shows the saine in connection with the bail pulley, which, however, has not a bail, but a headed bolt or Fig. 7 shows in perspective one of the gravitating jaws. Fig. 8 shows in perspective the gravitating catch block.

Referring more particularly to the reference numerals in a lnore particular description of the device, 1 indicates the track which has upwardly and downwardly extending headed flanges and laterally projecting plain flanges, on which the wheels of the carrier run. The track is suspended by hooks 2 lo cated at intervals along the track and which engage by lips the head of the upwardly extending tlange. The trip block 3 consists of two duplicate parts or halves clamped to the head of the lower web of the track by means 45 of bolts 4 and 5. The trip block is provided with a double inclinedor cam face G on each part. The carrier consists of a frame 7. On each side of the frame and engaging in suitable 5o recesses to insure their retaining proper positions, are secured pairs of arms 8 and 9,

which extending above the frame carry the carrying wheels l0, 1l, and extending below the frame, carry rope sheaves l2, 13. The arms S and 9 are secured by bolts 14 and 15, and a bolt 16 which also serves as a pivot for the jaws. The lower end ot the frame is provided with a bell shaped mouth 17 which is located vertically between the sheaves 12 and 13 and is adapted to receive and guide the upper end of the bail pulley 18 into engagement with the

holding jaws

19 and 20. The jaws are located just within the bell mouth and are pivoted on. bolt 1G, and each is provided with aholding arm o., a securing and supporting projection b andacounter weighted arm c. Sliding in ways 2l,in the upper part of the frame, is a gravity catch 4block 22, having upwardly extending arms 22, having inwardly extending project-ions 22h, adapted to ride upon the cam faces of the trip block. The catch block is also provided with walls or shoulders 22C adapted to engage behind the projections b on the jaws, and secure them locked, or the catch block will become itself locked by the shoulders 22c engaging upon the top of the projections 5,1) of the jaws. On the trip block 3, are provided at each end shoulders 3a andl 3l against which the projections 22b engage when the catch block is in elevated position, and prevent the carrier from leaving the trip block. The bailpulley 18 is provided with a headed projection or spindle 1Sa adapted to enter the carrier, and the ends of the arms of the jaws are made hollowing to adapt them to engage it.

In operation the carrier is placed upon the track as shown, and the trip block is placed at the point in the track directly above the place where the load is to be received, and the trip block secured. The rope is placed over one of the sheaves, thence through the bail pulley and secured to the other sheave. The carrier is adapted to run in either direction from the trip block, depending on which way the rope is placed in. When the carrier in passing, along the track, arrives at the trip block, the projections 22h of the catch block ride up the inclines 6 on the trip block and raise the block 22 until the projections b on the jaws become disengaged, which allows the

jaws

19 and 20 to separate by reason ot the IOO counter weighted arms c, thus releasing the bail pulley. After the catch block has been vraised and has passed off from the highest part of the incline 6,11he block is supported and secured in elevated position by the projections l), ZJ on the jaws. In this position it prevents the carrier from leaving the trip block by reason of the ripper ends of the arms 22a butting against one or the other of the shoulders 3 or 3b of the trip block. When the bail pulley is elevated to the carrier by drawing on the rope R, the projecting end 182L enters the month of the carrier, by which it is directed against the counter weighted end c of the jaws, and continuing upward, throws the jaws from the position shown in Fig. 5 to that shown in Fig. G, the jaws at the same time centering the bail pulley projection in the carrier. When the jaws have been brought into the position shown in Fig. 6, the catch block drops in behind the projection b, b on jaws and secure them, at the saine time it becomes disengaged from the shoulders 3 or 3b, as the case may be, and the carrier is allowed to move off, the jaws supporting the bail pulley and load. When the carrier is returned to the trip block, the bail pulley is released by thel jaws and the carrier held as before described.

What I claim as new and desire to secure by Letters Patent is:

l. The combination in a hay carrier of avcar having an opening for receiving the bail pul- 1ey,a pair of independent jaws pivoted upon a common pivot located directly overl the bail pulley opening, each jaw having an upwardly extending projection, a sliding catch block having shoulders adapted to hold the projections together in locked position and to engage upon the ends of the projections and become itself locked, a trip block having inclined face and retaining shoulders, and a bail pulley, substantially as set forth.

2. The combination of a car having a bail pulley opening, a pair of jaws pivoted upon a common pivot located directly over the bail opening, each jaw having a projection eX- tending above the pivotal point, acatch block having shoulders adapted to engage the projections from the outer sides and hold them together, and a bail pulley having a headed spindle, substantially as set forth.

3. In a hay carrier the combination of a car frame, pairs of arms extending above and below the frame, intersecting each other, and carrying the track wheels on their upper ends and the rope sheaves between their lower ends below the frame, the frame having notches or recesses for receiving the arms and retaining them in their proper positions, substantially as set forth.

In witness whereof I have affixed my signature in presence of two witnesses.
