A loading skip ifor 5:3' single operator may readily engage the raising the concrete aggregates and charg- 11o ing them into a concrete mixer, not shown, is used. The end of the machine equipped with the skip 4 has the crane and grappling apparatus of my invention applied thereto. rlhis crane includes the mast 5 which is stepped upon an arm 6 pivoted to the trame 1 at 7, and directly supported upon a bracket 8 carried by one of the multiplanes 2.

rThe .mast 5 is equipped with the boom 9 braced by a guy rod 10, and at the base ot the mast 5 is a winding drum 11, the cable 12 of which winds about in opposite directions and leads ot to some suitable power driving means which enables the mast 5 to be driven positively in either ot opposite rotative movements, tor swinging the boom 9 in corresponding directions to carry a batch box 'trom an industrial car to the skip 1, and back again.

rl`he machines ot my invention, as generally depicted in Figure 1, are so large, having a capacity as large as fifty-six cubic feet, that power mechanism is necessary for preferred operation of machines ot' such size.

The batch box 13 employed by me comprises a body having the bottom dumping doors 14. Connected with the doors 14tare links 15 which lead to the upper portion of the sides ot the batch box, as seen in Fig, 3, an-d are attached to loops or eyes 16, the peculiar form ot which is best seen in Fig. 5.

The ends ot the batch box are provided with keepers 17 ot' somewhat U form rigidly secured thereto.

The hoisting means tor the batch box 13, as per my invention, comprises the constructions shown in Figures to 3 inclusive, rather than the construction which is illustrated in Fig. 1, which terms the subject matter oi an application tor patent separate from this one. 1n general principle the hoisting line control, however, is the same as shown in Fig. 1, where the hoisting cable 18 is seen as passing over a wheel 19 on. top ot the trame 2() of the machine, down thru a hollow portion ot the mast 5, under a wheel 21, thence out over a wheel 22 on the upper end ot the boom, thence down over a guide wheel on a cross piece 23 forming a part ot' the supporting and grappling means for the batch box. Frein the wheel 211. the cable or line 13 passes up around the second guide wheel coaxial with the wheel 22` thence down around the second guide wheel coaxial with the guide wheel 24; on the member 23, thence up to point of attachment 25 at the upper end ot the boom. As shown best in Figs. 3 and 5, my method of passing the hoisting cable 13EL about the guide wheels 22", 221, and 22C, on the boom 9, and certain guide wheels 24 on the cross-piece 23, is much the same previously described ertcept that the line is finally secured to-the cross-piece 23 and is looped three times at the upper end of the boom and twice about the guide wheels oi the member 23, all in a self evident manner on reference to Fig. 4. Also in my construction of Figs. 3 and 5, 1 support the batch box in two ways. 1n the tir-st place the cross-piece 23 is a door supporting bar or member controlling the opening and closing of the door owing to the provision or' chains 23a which connect said member 23 with hooks 26 adapted to engage in the loops or eyes 16 connected with the doors 141. 1n order that one man standing at a side or end ot' the batch box may manipulate the hooks 26 to engage them with the members 16,` l utilize a handle or bail 27 ot U form which is rigidly attached to the hooks 26 and capable ot rocking or tilting them to simultaneously engage them with the said parts 16.

Keepers 17 before mentioned are engageable by a second supporting bar 28 having seats in its opposite ends preferably to receive the keepers 17 when said bar is shifted lengthwise to cause its ends to be received by said keepers. On the bar 28 is carried the block 29 that carries the grooved guide wheel 30 about which the cable 18L is passed according to the method shown in Fig. 4,-, The operator who is to manipulate the handle or bail 27 may also readily manipulate the second supporting bar 28, which may be called the keeper engaging bar for the batch boi; 13. Connecting the upper end of the boom 9 and the block 29, or the bar 28, in practical effect, are the stop chains 31, two ot which are preferably employed so that the upper supporting bar or cross-piece 23 and guide wheel 30a mounted thereon may be disposed therebetween. rlhe cable in the construction now described is attached to thebar 23 at 32.

"With the construction set torth as above, it will be evident vthat it the engaging and supporting parts' of the grappling means are carried over the batch box 13 as it rests upon the industrial car, the operator may readily grasp the engaging` bar 28, and the bail 2'?.y as the cable 18EL is slaciked to lower these parts over the. car. An uphaul on the cable 13a will then lift the box 13 with its load or contents, and by throwing into operation proper control means, the drum 11 may be caused to turn by the` cable means 12 connected thereto, whereby to turn the mast 5 and swing the boom 9 to bring the box 13 over the skip si. The operator thereupon slacks out the cable 13il to lowery the apparatus to lbring the batch box 13 down almost into the skip et. The chains 31 are suliciently long and may be adjustable, so that as the batch box reaches about the position shown in Fig. 1` the chains 31 become taut when the cable 18a is laid out a sutticient amount. rThereupon the downward progress of the box 13 is stopped and 'the llt) ree

\ tremity thereof, a stop -in on the cable 18,

cable 181 permits further slackening of the 23 to lower thus the supporting cross piece lowering the hooks mitting the doors 14 to open and dump the contents of the box. An inhaul of the cable 1 8a nowV closes first the doors 14 by uplifting the supporting cross member A23, and when the doors are closed further movement on the cable 18L will exerta pull on the engaging bar 28 cooperating with the keepers 17, whereupon the boom 9 may be swung back over theindustrial ca1 body or truck and the batch box lowered into place on the latter to` be returned tothe place of supply of materials and be reloaded. Y

Referringnow to the construction in Figures 6, 7, and8. It willl be observed that a. large numberof the parts illustrated are substantially'the same as shown and described hereinbeforefand rare ,correspondingly numbered therefore. In the modified form, however, I provide on the boom 9, preferably dependent from the outer exbracket 34 arranged so that its lower end may abut with the member 23 at a. certain point in the upward movement of the latter. The hoistingr drum cable 181is'passed about guide wheels on the upper outer end ofthe boom and on the lifting vmember 23, substantially as illustrated in the diagrammatic view Fig. 8. lt will be apparent that by the operation of the cable 18a the batch Vbox-13 may be elevated a certainfdistance without dumping. `When the batch box is disposed above the place where it is to be dumped by hauling doors will be elev ted until the crosspiece orbar 23l abutsrwith the stop bracket. 34. lNhen thisabutment takes place the upward movement of the doors will cease because the doors are primarily connected with the member 23.. Further inhaul on the cable 18a will then causethe body of the batch box 13 to continue its upward movement and such movement relative to the doors 14 will cause an opening, or dumping action of the doors in relation to the body of the box. The rela.- tive movements of the parts-are shown in Fig. 7V where the dotted lines illustrate the member 23 as having reached its upper limit of movement and the additional dotted lines show the batch box body elevated some distance after the member 23 comes. to a stop enabling the dumping action of the doors 14 to take place. The arrangement of the parts and the construction of Figs. 6 to 8 is especially adapted for use where it is desired to dump the batch box .13 at ay point which is higher in elevation than the place from which the batch box is removed from the industrial car truck of which it forms the body. y

rlhe principal eects of the several con` structions of my invention are to employ 26 and links 15 and perthe box and its closed f batch box and the doors,

the cable as a single line operating 'means for raising the batch box from its` car, shifting it from the place where it vis to be dumped and then cause a relative movement of the body of the'box and its doors so that the doors assumel an open positionv the box and cause dumping off The relative movement of they in respect to its contents. doors and the batch box body may beestablished in either of the two ways shown in the drawings, and possibly other methods` of a correspond-ing nature.

the opening of the batch box may becaused to take place incident to a limiting ofthe downward movement permit additional its doors, or by permitting a limited upward movement of the doors anda continued or further movement of the batch boxbody after the doors have ceased to move upwardly therewith.

the manner of connecting ther YengagingV hooks' 26 .and the relative arrangement of' the engaging bar 28 makes for a saving of labor inthe" handling of the batch box, as one man can readily attend to this particular work while working fromv one side ofjthe box, inan evident manner.4
