accomplished by the application oi the air to the inaterial.

ln Figs. 3 and 4, l have shown, somewhat .diagrammatically, a ioriu or' jigging device to agitate the bags and also a iorrn o device for discharging the same. 1 is an arm pivoted to the frame and having a forwardly projecting lower portion 2 attached to a cross-bar 3. There must be two or more el the arms 1, and the cross-l bar 3 is thus arranged at one side ol' the bags While they are beingfilled. and thisvr arm-end ,2 is at each end of the bracket 3", to which the arm 2 is pvoted and which is supported by the two, rollers 3b 3 which travel between the guidey rails 6 6. The bar 3 has throiiglit a rod 4 on which are mounted within the bar 3 aserics of upwardly bent pusher fingers 5 5. A cross-rod 7 connects the two elbow crank levers iormed by the

parts

1 and 2, and this cross-rod 7 may be manipulated toinove the pusher fingers in or out to iorce the bags away from the filling tubes FP on which they hang. When they are forced from such tubes, they fall in the inclined position indicated in Fig. 3 against the back 8 oi the jigging board or frame. This back or traine-piece connects with the end -ij'ieees 9--9, 'which are mounted 'on the vertical parts VIT 1Q-10, which'are in turn supported by ,the pitman 1.1i-u Ll from the eccentric A12--12 on the shaft 13. Thus the ligging-board or frame is kept in vertical motion. y v

The bottom oi the frame lll, on which the bags really rest, is hinged at 15-15 so that itcan be swung down into the position shown in dotted lines in Fig. 3. A hole in the floor, at 16, permits the bags to drop through as they pass down the chute 17. ing from this .bottom 14, is the lever 18, with the treadle 19 hanging therefrom, so that the operator can easily restore the bottom to the position shown in'full lines in` Fig. 3. This bottom is held in such position by means oi the hooks 20-20, pivoted at 2l to the fixed bar 22-22,

associated with the jigging board and held in locking position by the spiral spring 23. The upper end of the hook 2() lies in the path of the bar 3, so that when the latter has moved far enough in, as indicated in dotted lines in Fig. 3, to tilt the bags over and free them irorn the tubes P, the hook will also be swung on its pivot and the bottom 14 will be released so that the bags can iall down as above described. These parts, as above suggested, are to be taken. diagrammatic and their'paijts may be greatly varied without departA ing from the spirit el this part ol my invention. What is here important is a j'igging board of such a nature that during a portion of the jigging process, the bag may be free to hang on its filling tube, while during the remainder of the process it is supported onv thejiggingboard. lt is also important to have some means ior pushing the bags off when they are filled. Thus un` i filled bags when put on the tubes Pl) with the bottom in the position shown in dotted lines hang ireely and though the jigging board is still being vertically moved, the bags arenot affected. When the jigging board .is thrown up into the position shown in full lines, it begins toiact upon the bags.

telerring toFigs. 5 and (i, l here show diagrammatical'ly a modification oi parts of Fig. 2. For example, if in Fig. 2, no means be'shown for pushing the filled bags oil", they will bang there, and it would only be The connection between the bar 3.

under certain special conditions or circumstances that 'they could be pushed ofi by the air\ pressure. I desire to combine plungers and an air device, sothat. the bags may be filled by air and then b e pushed ofi by the plungeyrs. The pipe SA is changed somewhat in term and located beyond the base-board A. This pipe is connected at its ends with arms S Sl from the eccen tric-strap S2 on the eccentric S3, driven by the shalt l S4. The plungers S5 consist each of a long inwardly projecting .portion which is supported in the tube-like part SG on the base A, and the projecting end of which is passed through the pipe S, being screwed so as to be air tight. This plunger S5 may be a tube with a small axial aperture S7 and it may be plugged at SS. A small perforation SJ in' this tube plunger within the pipe S, permits the air which is led to such pipe S by hose connection SO to pass into the tube aperture S7, and thence out of the end of such tube plunger.

The use and operation oi my invention are as iollows:

When a given kind oi material is `to be filled it may be applied to the storage hopper in suitable quantities. By the arrangement of the two board valves, attached to one and the saine operating arm, an intermediate set oi measuring compartments or hoppers may be produced. They, of course, may be dispensed with if they are unnecessary. When the arm is' thrown in one direction Vthe openings in the storage hopper are iree, and the material can flow thence into the meas` uring hoppcrs until all are filled. By reversing the arm the feed will be cut off bute-ach measuring hop-y I per will be connected with its appropriate downspout. As soon as this is done the material begins to How down'the spout into the lower semi-tubularportion. Assuming that the bags lare all in position and are held there by the spiral spring, they may now be filled by turning the air valve and allowing a current of air to flow into the pipe. Any desired pressure may be used as the case may require. This air escapes through the very small holes, lt, into the' back end'oi each of these semi-tubular parts whence it rushes ior Ward carrying a stream of the material into the bag, and also blowing the chaff, dust and the like from the material up through the hood or d'ischarge-way,4 A1. It will be understood that when the measuring hop'- `pers are filled the lever is reversed to cut oft the supply'above and permit the material from each hopper to flow into its appropriate down-spout. The vprocess of filling the bags will continue until each has lbeen filled, and the material has been entirely exhausted from each-of the measuring hoppcrs. .The lever can then be reversed and the bags be removed and new ones be slipped onto the tubes while the. material is re-filling the measuring hopper-s.

iisA

Oi course, it will be understood that the niaterial v can be supplied in any desired manner, and with or without measurement or by bulk or weight.' The essential point is that the material is fed by air pressure to the bag,vand that the chaff, dust and the like may be blown out of thematerial without other contrivance than that here shown. In order to inflate the bags, or blow the sizing out o them, the air may be turned on before the-supply of material is turned en. When thel jigging d evice is used, the bags are pushed oli when 4filled in a group, and then, by dropping them down the hinged bottom, they will `all slide out onto the chute below and thus to the packing-tables. There are many kinds ol' bags used and some o them are so shaped that. when empty they are much longer thunwhen filled. For example, the Satchel bottom bags are of this class, and it is necessary, in order that such bags may be properly filled, that the bottom may be properly expanded by the materiel from within before the jigging process begins. There muy be various reasons for this not necessarydiere to be dis'- cussed. In onyevent, with the device of Fig. 8, the,

bags are simply suspended from the filling tubes/'QQ und then supplied with a. certain quantity yof inatterinl. This drops down into the bag, expands the bottoni, and brings it into a. proper condition to rest upon. the bottom of the )ligging-board. ',The operator may then throw the bottom upmid thus the jigging is applied to the bags themselves." Some method of discharging they begs nutonnrticnlly er in groups is necessary, because, to pull them off by'hand, would be too' expensive and require too much time. f l

lfVith/regird to/the device of Figs. 5 nnd'iiLno such pushing-ofi' device ns than: shown HFigQS/is necesf sary for, when the bugs :ircdlleol7 theplunger will itself force material into the bug suilicientlyto fill the'snnie and .cause ybzig to be pushed ofi of the tube. I I. It is obvious 'that 'I have shown the ports in Figs. 5 and G dizigiznnmaticolly and it might be better to greatly/change these ports. The" openings from ther tube-like part `O into the hopper K ond the spout A1 should be controlled or of such size ns to permit.' the plunger to bring oboutthe described result.
