FRANK VENEER, OF GALESBURG, ILLINOIS.

CARRIER.

SPECIFICATION forming part of Letters Patent No. 643,785, dated February 20, 1 900.

Application filed November 24, 1899. Serial No- 738,155. (No model.)

To all whom it may concern.-

Be it known that I, FRANK WENNER, a citizen of the United States, residing at 215 \Vest South street, Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Carriers; and I do hereby declare the following to be a full, clear, and exact description of 'the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to carriers for removing hay and other articles from wagons, cars, &c., and placing the same in suitable storagereceptacles.

I will now describe my invention, reference being had to the accompanying drawings,

forming part of this specification, in which Figure 1 is a side elevation of the apparatus with the parts in the position ready to receive the lifting-block Withits burden. Fig. 2 is a similar view showing the lifting-block suspended in the carrier. I

Like symbols of reference indicatelike parts in both views.

In the drawings, 2 represents the frame of the carrier, said frame preferably being composed of the side pieces 3 3, secured together by bolts 4. Mounted in bearings in the upper portion of the frame are the rollers 5 5, adapted to fit and travel on the track 6 in the manner common to these devices, the track being supported by hangers attached to the rafters of the building. Secured to the under side of the track is the stop-block 7, having the depending lug 8. Also mounted in suitable bearings in the side pieces 3 3 are the locking-wheels 9 10 and the rope sheave or pulley 11. The hoisting rope or chain 12 passes around the pulley 11 and around a sheave 13, mounted in the lifting-block 1a, and is connected to the frame at the point 15. The lifting-block 14 has a downwardly-extending portion provided with a sustainingloop 16 and an upwardly-extending portion 17 provided at its upper end with a cross-bar 18, the purpose of which will be explained hereinafter.

The locking- wheels 9 and 10 are provided with the recesses 19 and 20, respectively, for engaging with the lug 8 of the stop-block 7 and the cross-bar 18 of the lifting-block 14.

The wheels 9 and 10 are also provided with the cut- away portions 21 and 22, respectively, which are adapted to engage with the locking-block 23, mounted in the frame 2, which block may be an integral part of the frame or be separate and secured thereto. The frame 2 is also provided with the slot 24 for receiving the upwardly-extending portion 17 of the lifting-block 14.

The wheel 10 is so weighted that normally and unchecked it will assume the position indicated in Fig. 1that is, will be in readiness to receive in its slot or recess 20 the cross-bar 18 of the lifting-block. The wheel 9 is so weighted that normally it will take the position shown in Fig. 2that is, will be in readiness for the reception in its slot 19 of the lug 8 of the stop-block 7.

The operation is as follows: The parts being in the position shown in Fig. 1-that is,

in readiness to receive the lifting-block with its sustained load-the rope 12 is pulled and the portion 17 of the lifting-block enters the slot 24 in the frame and, striking against the upper side of the slot 20 in the wheel 10, causes said wheel to revolve in the direction of the arrow thereon, which brings the portion 10 of said wheel through the portion 17 and under the cross-bar 18. The revolution of the wheel 10 thus caused brings the point 1O thereof beyond or out of the path of the part 9 of the wheel 9, and the part 9 by reason of the Wheel being Weighted will rotate into the recess 22 of the wheel 10. The wheel 10 is thus secured against movement in one direction by the contact of the point 10 with the wheel 9 and in the other direction by contact of the point 10 with the locking-block 23 and by the weight of the load. Consequently the lifting-block and its burden are held against downward movement until the locking-wheel 10 is unlocked from such position. The movement of the frame now in the direction of the arrow will cause the lug 8 of the stop-block to strike against the side of the slot 19 of the wheel 9 and rotate the wheel still further in the direction of the arrow thereon until the upper corner of the slot 19 in said wheel is below the level of the lower edge of the lug, when the carrier and its burden may be moved on the track 6 to the required position. After the disengagement of the burden the carrier is returned for a repetition of the operation. On the return of the carrier the lug 8 of the stop-block 7 enters the slot 19 of the wheel 9, which causes said wheel to resume the position indicated in Fig. 1. The passing of the point 9 of the wheel 9 out of the path of the point 10 of the wheel 10 permits the latter, by reason of its construction and the Weight of the lifting-block, to turn and resume the position shown in Fig. 1, which will carry the point 10 of the wheel out of the way of the cross-bar 18 and permit the lifting-block to be lowered. The engagement of the portion 9 of the wheel 9 with the wheel 10 and the point 9* with the lockingblock 23 prevents rotation of the wheel 9 until the lifting-block is again brought back and the cross-bar engages the wheel 10.

The advantages of my invention will be apparent. It is simple in construction, durable in character, and in so far as the looking feature is concerned entirely automatic in its action.

Various modifications may be resorted to by the skilled mechanic without departing from the spirit of theinvention or sacrificing any of its advantages.

1. The combination with a track having a stop-block, of a frame movable on the track and having a locking-wheel provided with a slot for engaging said stop-block, and a second locking-wheel provided with a slot and with a portion for engaging the lifting-block when the latter enters said last-named slot, said locking-wheels having each a recessed portion for engaging the other wheel.

2. The combination with a track having a stop-block, of a frame movable on the track and having a locking-wheel provided with a slot for engaging said stop-block, a second locking-wheel provided with a slot and with a portion for engaging a lifting-block when the latter enters said last-named slot, said locking-wheels having each a recessed portion for en gaging the other wheel, and a lock-block for engaging said recessed portions of the locking-Wheels.

3. The combination with a track having a stop-block, of a frame movable thereon having aweighted locking-wheelmounted therein and provided with a slot for engaging said stopblock, a second weighted locking-wheel provided with a slotand with a portion for engaging a cross-bar on a lifting-block when the cross-bar enters the last-named slot, and a lock-block on the frame for limiting the motion of said wheels.

4. The combination with a track having a stop-block, of a frame movable on said track, a locking-wheel provided with a slot for engaging said stop-block, a second lockingwheel mounted in the frame and having a slot and a portion for engaging a cross-bar on an upwardly-extending portion of a lifting-block when the latter enters said lastnamed slot, each of said wheels having a recessed portion for engaging with the other wheel,and a lock-block for limiting the movement of each of said wheels.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK 'WENNER.
