camz. r. Bnos'rnom Nn FRANK LANG; or EAGLE BENn-rINNEsoTA- Be itlmown that we, CARL F. BnosrRoM and-FRANK LANG, citizens ofthe United States, residing-at'Eagle Bend,-in the county -o' Todd and State of Minnesota, have in vented a newand useful Litter-Carrier, of

^ which the followi'n is a specification.

Our inf.- ention r e ates tol litter carriers but" Y may also be applied to carriers in general,

for ore, coal, earth, sand-pte., and the object 1s to improve such carriers 'as hereinafter s et forth and pointed out in the appended claims.

In the accompan ing drawing, Figure 1 'is a side 'elevation o our litter-carrier shown' as suspended from atrack wire or cable. Fig. 2 is an end view of Fig. l. Fig. 3 is a top View of the track wire and the portion of the device aboveA it in Fig. 1. Fig. 4 is a section on line a-a in Fig.'1. Fig. 5 is an enlarged -and modified side view lof the abutment on the track wire or cable that trips the device. Figi. 6 is a leftA end view of the receptacle so that they may swing t0 the open positions shown in dotted lines in Fig. 2 for emptying the receptacle by dump .ing .or .droppin its contents out. 'Each of said wings Y or ottoni sections is normally held closed by a spring 5 laced on the hinge pintle 6 and engaging wit i'one end the wing and with the other' end the side of the re-A ceptacle. To preventpremature opening' of l the bottom sections when therec tacle' is a vertical lever?, pivoted at S and having a {in ger4 9 4adapted to enter apertures l0 in the fixed to 'the ends of the receptacle and has its horizontal bar 1 3x extending l o'ngittldmallyf Lrrrnacnnmnn.

and centrally above the receptacle. To said 'I bar 13x are journaled two vertical hangers 14., each with'a grooved pulley'15 adapted to ride on the cable 1. Y The top of the hangers are connected by a horizontal brace 16 havin its lends 'pivoted at 17. The endsof p" ey shafts 18 are extended in opposite directions beyond the hangers, and each, such end is pivotally secured to the ends of a rod 19 passed 'dia' onally between the two hangfers, so that w en the track 1 is curved laterally the two pulleys will more readily follow the curve, as shown in Fig; 3. l

The hook levers '7 have their upper ends 'connected-'by rods 20 and 20? to a trip lever 22, which is' pivoted at 23 to the bail and has its upper end provided. withal head 24C4 having a gap 25 for 'the track wireand transversely thereto a notch 26 for engage y ment with an abutment 27, which is'made in two halves secured on the track wire, ,partly by a clamping bolt 28 andpartly by 'a cam'lever .29 mounted on the bolt between thehalves of the abutment. Theflatter are held-in non-rotatable` position on the boltl by`a.'pin 30 passed through them at the point where a support 31 holds them apart `so as-to create a space for the cam between them.

The rod 20 is at all times impelled upwardly by a` spring arm' 32 fixed at 33 to the bail, whereby the trip-lever 22 is normally held at an incline either as in the full line or in the dotted line position shown in Fig. 1 and thereby holds the hooks 9 either engaged or in disengaged position. .There isv also provided on the rod 20 a coil spring 34, which is. normally partly compressed lbetween a collar 35 on the rod and a support.-

ing arm 36, -pivoted at 37 (see Fig. in a lug'38 on the bail, saidsupport has a notch 40 for the rod 20, and is held bya spring 39 in contact with the rod 20, and also, when so desired, in the disengaged position shown in dotted linein Fig. 4:.

' .In operation, the track wire 1 may be horizontal 4or inclined,4may extend from a certain placejto another, 'orit may be endless, returning 'to its starting point. In using the device for the removal of litter from a s table out to acertain point on the higher up to'a post or tree beyond the,v

the hooks 9 and' lets the load field the track wire is -'xed with one end to or near the stable, and the other end a little dumping place, the receptacle is filled and given a good ush as from left to right in pin-.the stable, it then runs valong until the 'notch 26 is-engaged by the 'abutment 27, whichtilts lthe tri lever to ig. 1, away;

the dotted position and thereb isengages ro throu h the bottom which is opened by t e weig t of tha-litter. As soon as the load is out the springs 5 close the bottom again and as the gravitycomniences' to move the device back again toward the barn, the trip lever is operated inthe opposite direction by the same abutmentl and thereby the hooks 9 are' again engaged-` with lthe bottom sections to lock them in the closed position, and the receptacle is thus ready to receive. the next load.` Thlsgoperation of the trip lever and the hooks 9 is the same if the receptacle -is I hauled-back and forth by an endless cable' and ower. But if the track or track wire is Q the endless type, the spring arm 32 1s dlsengaged from rod 20 an or arm 36is swung downinto meeting contact with the endeof the spring 34, and the latter tends to hold the trip lever always in the sameA one inclined position and throws it back to that position and locks 'the bottomsections aft-er the load has been emptied by the action of the abutment on the lever in one direction.

' To make the device at different places it is only necessary to move the abutto the upper part of the frameaand having' two opposite arms extending one-above' and the other below its fulcrum, a rodextending from each locking lever and connected withthe trip lever, one-above and the other below its fulcrum, said trip lever havingliu its upper end a notch for engagement withl the abutment to operate the lever "and llet it pass in either direction, and a .spring arranged to hold the trip-lever inclined with its notch in position to engage the abutment. 2. The combination with an elevated track and a tripping abutment secured thereon and projecting from the lower side thereof,
