BATCH-BOX-HOISTING APPARATUS.

Application filed July 3,

ing Apparatus, of which the following is a specification.

The present invention has to do with what is known as batch box apparatus. In the art of handling materials such as concrete aggregates, transported in industrial railway cars which comprise the batch boxes as the car bodies, a crane is generally utilized to lift the batch boxes off of the car trucks when the cars reach the site where the concrete aggregates are to be used.

The object of the invention has been to design grappling and hoisting apparatus for the batch boxes, capable of being readily engaged therewith by a single operator, and additionally capable of lifting boxes from a position at a higher or lower elevation than the elevation at which the boxes are to be dumped.

In the accompanying drawings;

Figure 1 is a side view of a portion of a crane, a batch box, and grappling, hoisting and dumping apparatus of my invention associated therewith.

Figure 2 is an end View of the batch box and certain parts of the hoisting and grappling apparatus showing more clearly features of construction not disclosed to best advantage in Figure 1.

Figure 3 is a plan view of the batch box and certain of the engaging barand other parts. 7

Figure 4 is a sectional View showing more clearly the stop hook on the mast of the crane before engagement of the stop therewith.

Figure 5 is a View like Figure 4:, excepting that the stop is in position to engage the stop hook.

In Figure 1 are best shown the various features of my apparatus. At 1 I designate the mast of any suitable crane comprising the said mast and a boom 2 braced by a guide rod 3, these parts being illustrated in, a fragmentary manner since they are conventional. The mast 1 is adapted to rotate in suitable bearings or brackets, one of which is shown at 4* in Figure 1, and upon whatever part is used to support the mast, the latter part- 1922.

not shown. The batch box 5 comprises a pair of bottom dumping doors 6, links 7 in the opposite ends of the box connected with the doors 6, and havingloops or eyes 8 forming connections for their upper ends. Hooks 9 engage in the eyes 8 and are adapted to be simultaneously handled or manipulated by being connected together rigidly by a handle or bail 10. On the sides of the door of the box 5 are keepers or loops 11 with which may be engaged the engaging bar 12. A fabricated channel structure comprises a cross piece or hoisting bar 13 equipped with a pair of grooved guide wheels 14, about which the hoisting cable 16 is looped, as best shown in Figure 1, said cable being attached at one end at 17 to the upper end or the boom 2, passed downwardly around one of the wheels 15, upwardly around a similar wheel 18 on the upper end of the boom, downwardly around a second of the Wheels 15, and upwardly over a similar wheel 19 on the boom 2, which is above the wheel 18. From the wheel 19 the cable 16 passes to a guide wheel 20 on a bracket 21 adjacent the mast 22, after which the cable is let off to any suitable power operated drum winding means by which the cable is wound in and let out. Attached to the engaging bar 12 as a sort of counterbalancing means therefor, is the chain-23 which has the branch chains 24 at one end directly connected to the bar 12, the other end of the chain 23 passing over a similar guide wheel 2% coaxial with the guide wheel 19, the chain thence passing over a similar guide wheel 25 on the bracket 22 and extending downward parallel to the mast 1 and having secured thereto the weights 26. The weights 26 may be guided by a guide rod 27, if desired, and the chain 23 carries a stop 28 adjustable thereon. As seen in Figure 1, there is located in a stationary position adjacent to the mast 1 a hook or abutment 29, see also Figures 4 and 5. This hook or abutment 29 is located so that under certain conditions it cooper-- ates with the stop 28 on the chain 23, and under other conditions there is no cooperation, during movement of the chain.

The operation of the invention may now be described. \Ve shall assume that in Figure 1 the batch box is located above the truck of the industrial car of which it forms the body, and an operator has by manipulation of the engaging bar 12, en-

gaged it with the keepers 11, and b manipulation of the handle l0 has engaged the hooks 9 with the loops or eyes 8. By inhaul on the cable 16, and further assuming that the parts have the relative ar rangement of Figure at, there is an upward pull upon the lifting bar or cross piece 13 and lowering of the stop 28, and in this way the batch box 5 through the connections between the member 13 and the hooks 9 may be readily lifted oil of the industrial car. lVhen'so raised the batch box 5 may be swung into a position over a skip or other receptacle into which it is to be discharged, by turning the mast l and swinging the boom 2 which is carried thereby. When the batch box hasbeen swung into its dumping position just referred to, the chain 23 will be received by the hook 29, with the stop 28 beneath the latter, and the degree of swinging being illustrated somewhat by the positions of the chain in Figures i and 5. By letting out on the cable 16 after the chain 23 has entered the hook 29, and after the box 5 is of course in its dumping position, the supporting or lifting bar 13 will'be lowered, lowering the box 5 and pulling downwards on the chain 23. This action-raises the stop 28 and when the stop 28 reaches the hook 29 lowering movement of the box is stopped by the discontinuance of downward movement of the engaging bar 12; Thereupon the continued letting out of the cable 16 permits the doors 6 to move downwards whilst the box 5 is stationary, thereby dumping the boxand emptying An inhaul of the cable 16 after the dumping operation described first raises the doors 6 to closed position and then causes the box 5 to beraised during whichoperation the counterbalancing weights 26 move downwards, as well as the stop 28. The crane may then swing the box back to its position over the'truck of the industrial car, the chain 23 disengaging tromthe hook 29, and the box may be lowered until it rests on the'truck, whereupon the operator will disengage the parts 9 and 12 from the co-aeting parts of the box 5, and thus release the cables and hoisting equipment from the batch box.

As above suggested the primary purpose of the weights 26 is to counterbalance the bar 12 so that the latter will always hand and available to be grasped by the operator to engage it with the keepers 11 on the box Obviously the apparatus described is one wherein the batch box is lifted from a position at a higher or lower elevation than the elevation at which the box is to be dumped.

The hook 29 is adjustable verticallyof the mast, being held in position thereon by any suitable clamps at held by bolts. It will be obvious, therefore, that the hook 29 may be elevations than the particular elevation at which the batch box or boxes must be dumped. By adjusting the hook 29 to a lower position relatively to the mast 1, and correspondingly adjusting the stop 28 on the chain 23, the derrick can pick up the boxes at a still lower elevation thanaccording to the arrangement which is illustrated, the dumping of the bucket of course being always controlled by the position of the hook 29. The maximum height at which the boxes may be pickcd'oli' 01'? the cars, or the car trucks, more precisely speaking, is only dependent upon the height of the derrick mast 1'.

Havingthus described my invention what I claim as new and desire to secure by Let ters Patent is,
