.This invention relates to a bag or sack holder, and it is primarily an object of the invention to provide an apparatus of this kind which initially maintains or supports a sack or bag with its mouth open to facilitate filling and which also operates to close said mouth after filling so that I the mouth portion of the bag will be in proper position for sewing or the application of other fastening means.

m It is also an object of the invention to provide an apparatus of this kindwhereby the bag or sack supported. thereby after having its mouth portion closed can be readily released.

The invention consists in the details of con- 15 struction and in the combination and arrangement of the several parts of my improved bag or sack holder whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better 25 understood, I will now proceed to describe the Figure 3 is a view similar to Figure 2 but showing the device in open position to receive the mouth portion of a' bag or sack, the holding latch and other parts being omitted;

As disclosed in the accompanying drawings, B

denotes a supporting beam for my improved apparatus although I do not wish to'limit myself to the use of a beam as any other element possessing the requisite strength and having the required 15 dimensions may be employed with equal facility.

Held by the stud bolts' l or otherwise to the under surface of the beam or support B at desired spaced points therealong are the blocks 2 of required dimensions. The inner end of each of said blocks 2 at its lower portion is provided with an inwardly disposed extension 2'. The blocks 2 proper are also provided in their upper surfaces with suitably spaced recesses or slots 3 to receive the stud bolts l hereinbefore referred to. At this time I wish to state that I do not care to be limited as to the manner of securing the blocks 2 in place.

The outer end of each of the extensions 2' is provided with a socket 4 which rotatably receives an end portion of a main bag or sack holding bar 5 and said bar 5 at a point immediately adjacent to the free end of one of the extensions 2' carries an outstanding segment plate 6. This plate 6 is of desired dimensions and, as herein disclosed, one end thereof contacts with the extended end portion of a sliding bolt 1 whereby the extent of rotary movement of the bar 5 in one direction is positively limited. This bolt 1 is slidably disposed through two upstanding lugs 8 carried by the extension 2 of one of the blocks 2. The bolt 1 between the lugs B has disposed therethrough a pin 9 and interposed between this pin 9 and the inner lug 8 is an expansible spring encircling the bolt '1. This spring H3 serves to normally maintain the arm I projected in the path of travel of the segment plate 6.

Encircling each end portion of the bar 5 is a coil spring ll. One extremity of each of said springs is secured, as at l2, to the bar 5 while the opposite end portion thereof is anchored, as at I4, to the free-end face of the adjacent extension 2' of a block 2.

. When the bolt 1 is extended for contact with the segment 6, the bag engaging hooks l5 carried by the bar 5 are disposed upwardly as desired to properly and eifectively hold the portion of a bag or sack engaged therewith. However, when the bolt 1 is retracted in a manner which will hereinafter be more particularly referred to, the weight of the contents of the bag or sack upon the hooks I 5 will cause the bar 5 to rotate inwardly and downwardly a distance sufficient, as particularly illustrated in Figure 11, to allow the bag to readily free itself from said hooks l5. During this movement of the bar 5 the springs II are placed under tension so that promptly upon freeing of the bag from the hooks I5 the bar 5 will rotate upwardly and rearwardly and thus return the hooks i5 to their desired raised position to be engaged by another bag or sack.

It is to be noted that the segment 5 at its peripheral portion is of such length to hold the bolt i retracted during the entire period the bar 5 is swinging downwardly and until the bar 5 swings upwardly a distance suflicient to cause the plate 6 to pass entirely beyond the bolt l whereupon said arm 1 under the action of its spring 10 will be projected for proper engagement with the segment 6. Each of the blocks 2 is provided therethrough in its lower portion with an elongated slot it which extends within the extension 2 of the block. This slot I6 is horizontally disposed and the outer portion thereof is intersected by a vertically disposed slot I! or, in other words, the slots l6 and I! are in right angular relation.

Extending through each of the slots I6 is an elongated flat arm I8, said arm I 8 extending at all times beyond the opposite sides of the block 2 and its extension 2'. The arm it has disposed through its middle a tight pin E9, the end portions of which freely work in the slot I! above and below the slot Hi. This pin l9 provides a pivotal mounting permitting the arm I8 to readily swing and at the same time the slot ll will permit said arm l8 to have limited movement in a direction lengthwise of the bar 5.

Each arm l8 for each block 2 carries a head 20 while the end portions of these arms !8 at the opposite sides of the blocks 2 are tied or connected by an interposed retractile member 2| of desired strength and herein disclosed as a coil spring. This spring 2! serves to constantly pull the ends of the arms l8 remote from the heads 2!] one toward the other but limited by contact of the pins [9 with the inner ends of the slots l1 and by the contact of the heads 20 with the adjacent sides of the blocks 2.

The inner end of each of the heads 29 has disposed lengthwise therethrough an opening 22 which has disposed therein an end portion of a tubular bar section 23. This tubular bar section 23 has a slot 24 disposed lengthwise thereof and inserted within the end portion of this bar section 23 within the opening 22 is a solid filler member 25. The member 25 is keyed to the bar section 23 by a pin 26, the extremities of which extending beyond the tubular bar section 23 and engaging within the slot 21 whereby the bar section 23 is held against endwise movement with respect to its head 20 yet is permitted to have limited rotary movement.

The ends of the bar sections 23 remote from the heads 20 have telescopically engaged therein the reduced extensions of the hinge members 28. These members 28 are pinned, as at 29, or otherwise securely held in position. These hinge members 28 project a desired distance beyond the adjacent ends of the bar sections 23 and are formed and constructed to interlock so that a pivot member 30 may be suitably disposed therethrough to pivotally connect the inner end portions of the bar sections 23. This pivotal connection at 30 permits the inner end portions of the sectional bar 23 to swing outwardly away from the main bar 5 as the arms l8 move inwardly of the slot H and swing upon the pivot members l9 under the action of the retractile spring 2i.

Freely mounted within each of the bar sections 23 for movement endwise thereof are the blocks 3| and extending outwardly from each of these blocks 3| and passing out through the slot 32 of the bar section 23 are the bag engaging hooks 33. Interposed between adjacent blocks 3i and between an end block 35 and the inner end of a filler member 25 and also between the second end block 3| and a hinge member 28 are the expansible separating members 34 herein disclosed as coil springs. These springs are of a tension to normally maintain the blocks 3! in desired spaced relation but readily permit the blocks 3| to have movement lengthwise of the bar section as the bar sections 23 are moved into or out of parallelism with the bar 5, thus permitting proper adjustment of the hooks as the bars close the sack.

The hooks 33 carried by the bar sections 23 are also normally upwardly directed as preferred. The filler member 25 of one of the bar sections 23 extends outwardly a slight distance beyond its associated head 25 and said extended portion carries a segment 35, one end of which, as particularly illustrated in Figure 7, contacts from below with an extended end portion of a bolt 36 whereby the hooks 33 are held in their normal raised position. This end portion of the bolt 36 is maintained projected by the coil spring interposed between one of the bearings 38 through which the bolt 36 moves and a stop pin 39 disposed through the arm 36.

Upon inward movement of the bolt 36 the extended portion will be retracted to release the segment 35 whereby the weight of the filled bag will cause the bar sections 23 to swing downwardly a distance sufficient to allow the bar to pass therefrom. As these bar sections swing downwardly and inwardly they place under tension the springs 49 encircling the outer end portions of the bar sections 23 and secured, as at 4| to said bar sections and as at 42 to the adjacent ends of the heads 20. This tension of the springs 40 is sufficient to rotate the bar sections 23 upwardly as the bag is disengaged therefrom to return the hooks 33 to their normal raised position and with the arm 38 projected to engage an end of the plate 35 to hold the hooks 33 in such raised position.

It is to be noted that this segment 35 is of a length to extend over the adjacent end of the bolt 36 when retracted and at all times during the downward movement of the hooks 33 so that said bolt 36 will not be projected until after the plate 35 has been swung back to its normal position.

The inner end of the bolt 36 carries an upstanding post 43 with which is adapted to contact an end portion of a swinging lever 44. This lever 44 is pivotally connected intermediate its ends, as at 45, to the upper surface of the extension 2 of a block 2 and the outer end portion of this lever 44 is freely disposed through the end "portion of the bolt 1 remote from the plate 6: of

the bar This lever 44 when pushed in one direction by hand, or automatically as disclosed in my application for patent on a bag sewing apparatus: executed on even date herewith; will simultaneously move the bolts: 1 and: 36 into retracted position so that the hooks l5 and. 3-3: may readily swing downwardly under the weight of a filled bag torelease the same. This releasing action preferably takes placeafter the mouth portion of the bag which has previously been. held between the bar 5. and the closed bar sections 23 has been sewed or otherwise closed.

Normally, the bar sections 23 are in. the positionillustrated in Figure 3 and which arrangement readily allows the desired application to the holder of the mouth portion of an empty bag. After the bag, has been. filled, as by discharge through a grainspout or otherwise as may be ure 5) wherebythetbar sections 23' will be maintained'in. such closed position until the latch is moved into released position as by an operator striking or pressing the .latch ,46 from below. This latch 46: has a tailor stem portion 4'! which is hingedly connected at a desired point intermediate its end, as at, 48, to a side face of the beam or support B. This tail or extension 4'! ex" tends beyond the opposite side of the beam or support 3 and, underlies-an outstanding bracket 49 carried. by the beam or support B.

Freely disposed through the overlying portions of the extension or tall 4] and bracket 49 is a headed shank 50, said shank having a nut 5| threaded upon one end portion thereof and engaging the. extension or tail 4'! from below. In-

terposed between thebracket 49 and the head 52 of the shank 50 is an expansible member 53 herein disclosed as a coil spring encircling the shank. This spring 535 is of desired tension and serves to normally maintain the latch 46 in its working position yet permits the same to readily swing uponits hinge 48 to have proper engagement or disengagement with its associated bar section 23.

Disposed along the inner portion of the bar 5 and fromsubstantially one extension 2' to the other and also extending along the major portion of the. bar sections 23 below the hook members l5 and 33 respectively are flanges 54. These flanges 54: extend inwardly one toward the other and when the bar sections 23 are in closed position the outer free longitudinal edges of the flanges 54' closely approach each other. 'These flanges serve to effectively hold the mouth portion of the bag in closed position and in proper formation over the bag content so that the sewing or other closing operation may be materially facilitated. It is also to be stated that with the use of these flanges 54 it has been found possible to sew or close the bag closely adjacent to its upper free margin with a resultant increase in bulk of material within the bag or sack.

From the foregoing description it is thought to be obvious that a bag or sack holder constructed in accordance with my invention is particularly well adapted for use by reason of the vious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood. as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention" in practice except as hereinafter claimed,
