SACK-HANDLING MACHINE.

Application led March 19, 1924. Serial'No. 700,200.

To all whom 2f may concern Be it hereby known that I, IRA T. ENG Lrsrr, a citizen of the United States, anda resident of Portland, in the county ofl Multnomah and State of Oregon, have invented a new and useful Sach-Handling Machine7 of which the following is a speci- 'i iication.

This invention relates to the handling of grain and similar materials.

An object of my invention is to provide an exceedingly simple and efficient sack handling machine which will transport sacks of grain horizontally or up an incline, and empty the sack of its contents at a given point.

A second object iste provide means for holding the saclr while emptying.

A third object is to provide means for assembling emptied sacks in shape for securing same in ybundled form, or for sorting. A fourth object is to so construct the machine that its pointof emptving can be readily varied. f

I accomplish these results in the manner set forth in the following specification and illustrated in the accom an 7in@` drawinfrs in which Figure 1 is a lsideV elevation of my device on a reduced scale of which Figure 2 isa front elevation and Figure '3 is a plan. Figure 4 is a vertical section along the line l--fl in Figure 1. Figure 5 is` an enlarged vertical section along the line 5-5 in Figure 6. Figure 6 is a vertical section taken along thel line 6 6 in Figure 5. Figure 7 is a section along the hne7-7 in Figure 5. Figure 8 is a bag assembling device.

Similar numbers of reference refer to the same parts throughout the several views. i Referring in detail to the drawings, I have illustrated my device as mounted on a base consisting of the horizontal members 10 which are joined at their forward end by a tie 11. rlhe members 10 and 11 are supported bythe casters 12. v

Against the inner side of the members lO I have hinged the upright standards 13 en the shaft lll whose outer end is provided with a slidable handle 16 and a ratchet wheel 17 which engages a. pawl 18 on 'one of the members 10. Cable drums 19 are secured on the shaft lll. On the inner sides of the upper ends of the standards 13 I have mounted the pulleys 2O on the shaft perspective of the 2l, which also serves as a tie between the members 13. Cables 22 wind around the drums 194 and ypass over the pulleys 20.

On the rear end of the members 10 I' have mounted the bearings 23 which carry the 'shaft2l, which also serves as a tie between the members 10. On the center of the shaft: 241- Vis placed a wide'pulley 25. Between the pulley 25 and they bearings 23 I have placed the bearings 26 on which are slid-` ably mount-ed the two angle irons 27 provided with a spacer 28 whose screw 29 bearsr against the bearing 26 'and serves yas a tight ener. Spacer collars 'SO are placed between the members 25 'and 25 and spacer collars 31 are placed onthe shaft 2e between the me1nbers23 and 26."

The forward ends of the angle irons! 27 are separated by thebearing blocks 32 and se* cured the-reto. A shaft 38 bears in the blocks 32 and has on one end a large spreche 34. A wide pulley is secured on the shaft- 33 and a wide conveyor 36 passes-around the pulley 25 and 35 and can be driven by the sprocket 34. A iioor 37 isV provided under the upper run of the conveyor 36. Suitable upright supportsSS for the floor 37 are mounted on the angle irons 27.-

vBetween the members 27 is mounted a counter shaft 39 whose sprocket 40 drives the sprocket 34 through the chain 41. On the counter lshaft 39 is alsoplaced a pulley 4t2 which is driven t-hroughthebelt rby the motor alwhich is mounted on the raised base L15 sufficiently highV to permit sacks of grain on the conveyor 36 to pass freely under same.

Attached to the lowervmembers 27 is a transverse angle iron i6 from which is hung the arms 47 whose bent lower ends 48 are secured to a horizontal l iron Shelably placedV on the member LlQis a sack gathering or assembling frame 5()v provided with a handle 51' and the long straight needle-s 52 which are held practically parallel to the lower run of the conveyor 36. @n the conveyor is placed a. plurality of sach supports Each support 53 has its lower edge curled to receive a pivot 54 which is supported by the standards 55 formedon the strap 56 which, in turn, is secured to the conveyor 36. A similar strap 57 is secured to the'conveyor 36 a short distance fromthe strap556 and carries the brace rods 58 which engage the curl 59 on the uploo per end. ,of the snol;A 'suppprts 5.3.- These braceshold the member 53 rigid with rela,-

tion to the conveyor 36 and yet permit its easy movement around the pulleys and 35,.

On the rear side edgesni'fthe linemiloers 53 are secured thebearings (SO-Which carry a.v pivotally mounted flat 'ba-r 61 providedvvith rounded ends 62 Whichgjdurnal in the; beany ings 60. Eaoh bar 61 is provided With curved needles which arexhent': onI a. radius.

Whose center is; the axis` olf the shaftrend 62.*.

On one of the endsiZ I have secured aA rocker arm 6.4. provided with a rol-'ler 65 which can engage the somewhat. blunt-lendsV 6.6.01l the angle. iron trackjffand mindingH upon said tra-cli ca ise said. curved needles to'be passed throughl thesack sup-port and tlie'bottom of any sack which inayi'ibe restingV upon same.

The sacks on the filled frame are now seivied to- `rether and the needles 52 Withdrawn and the fra-ine 5() made available for other sacks.

In this Way no straightening of sacks is required and they areall put in vshape for handling. n

In some cases it may be preferable to tie these sacks,l as is c-omn'ionlyunderstood,

which, of course, would not `interfere with the operation of. sackgathering.
