2 Claims. 1

This invention relates to bag holders and more particularly to a holder for su porting the open end of a bag of flexible material, such as cloth, in open condition while the has is being filled with material, such as grain.

It is among the objects. of the invention to provide an improved bag holder for supporting the open, ends of flexible bags in open condition, which holder is quickly and easily adjustable in height to accommodate bags of different lengths and to permit the starting of the bag filling Operation at a low level to avoid unnecessary lifting and gradually raising the open end of the bag as the bag is filled, which provides for tilting the open end of the bag to facilitate filling thereof, which is easily adjustable in size to accommodate bags to different sizes, which is of light Weight and easily reducible to a compact condition for transportation or storage, .and which is, simple and durable in construction, economical to manufacture, and easy to use.

Other objects and advantages will become apparent from a consideration of. the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure l is a front elevation of a bag holder illustrative of the invention with a bag operatively supported thereby;

Figure 2 is a side elevation of the bag and bag holder assembly illustrated in Figure 1;

Figure 3 is a top plan view of the bag holder;

Figure 4 is a cross sectionon an enlarged scale on the line 4--4 of Figure 1;

Figure 5 is a cross section onan enlarged scale on the line 5-5 of Figure2; and

Figure 6 is a cross section on an enlarged scale on the line 5-6 of Figure 3.

With continued reference to the drawing, the bag holder comprises two elongated, substantially straight legs l and II. A foot piece or foot I2 is secured to the leg It at one end of the leg by suitable means, such as the bolt I3, and extends to opposite sides of the leg substantially perpendicular to the latter. A pad 14 of antislip material, such as soft rubber, is secured to the end of the leg and to the surface of the front 12 at the corresponding end of the leg. A similar foot I is secured to the leg H at one end of the latter by a bolt l6 and an antislip pad I! is secured to this end of the leg and to the surface of the foot adjacent the end of the leg at which the foot is attached.

A generally annular band 18 of thin walled flexible material, such as tempered steel, has overlapping end portions l9 and 20 and is of a size to fit within or around the open end of a bag, such as a grain bag.' U clamps 2! and 22 receive the overlapping end portions of the band l8 and are apertured at their open ends to receive clamp bolts 23 and 24' respectively. A wing mitt-5 is threaded onto the bolt 231 and a similar, wing nut 26 isthreaded onto the bolt 24 for clamping the overlapping end portions of the band {8 together against movement. relative to each other.

With this arrangement. the

wingnuts

25 and 26 can be loosened and the band l8 adjusted to accommodate it to bagsofa selected size and then the wing nuts tightenedv .to secure the band in the adjusted condition.

The leg I I is provided near its end opposite the foot It with a tapered hole 21' and the leg HI is provided near its end opposite the foot 12' with a similar hole, not illustrated. The band I8 is provided with bolt holes at substantially diametrically opposed locations therearound and a bolt 28 extends through one 01' the bolt holes in the band l8 and through the tapered hole near the end of leg I!) opposite the foot If! while a similar bolt 29 extendsthrough the other bolt hole in the band and through the tapered li'ole IT-in-the leg H.

The end of the leg Ill opposite the foot I! is disposed at the inner side of the band l8 and the bolt 28 extends through the bolt'hole-in the end of the leg 3! oppositethe foot l2 and through the corresponding bolt hole in the band. The bolt has a head 30 at the inner side of the leg and a washer 3t surrounds-the bolt between thehead 30 and the leg It. A coiled compression spring 82 surrounds the bolt 28 at the outer side of the band l8 and bears at one end against theband. A washer33 is placed on the bolt 'atthe outer end of the spring 32 and a wing nut 34 is threaded onto the bolt and bears against the washer 33 to compress the spring.

The end of the leg ll opposite the foot I5 is also disposed at the inner side of the band l8 and the bolt 29 extends through the hole 21 in this leg and through the corresponding bolt hole in the band. This bolt has a head 35 at the inner side of the leg I I and a washer 34 surrounds the bolt adjacent the leg ll while a washer 36 surrounds the bolt between the bolt head 35 and the leg II. A compression spring 31 surrounds the bolt 29 at the outer side of the band l8 and bears at one end against the band. A washer 38 is placed on the bolt at the outer end of the spring 31 and a wing nut 39 is threaded onto the bolt 29 and bears against the washer 38 to compress the spring 31.

With this arrangement the feet I! and I at the lower ends of the legs and Il may be spread apart, as indicated in broken lines in Figure 1, to lower the band It to accommodate the height of the band above the floor to the length of a particular sack and also to lower the band so that the bag filling operation can be begun at a low level to avoid unnecessary lifting of the material being placed in the bag. The legs I0 and H are held in downwardly diverging condition by the antislip pads 14 and IT and also by tightening the

nuts

34 and 39 against the

springs

32 and 31 to tighten the connections between the legs and the band. The pivotal connections provided by the

bolts

28 and 29 between the legs [0 and H and the band l8 also permit tilting of the band, as indicated in broken lines in Figure 2, to facilitate filling the bag, this tilting movement being limited by the shoulders 42 on the legs. With this arrangement the bag holder will stand up on a smooth or slippery surface or on an uneven surface such as the surface of a cultivated field.

Suitable spring clips 40 are attached to the band It by suitable means such as flexible strands, and are utilized to clamp the portion of the bag at the open end thereof to the band. In securing the openend of the bag to the band IS the end portion of the bag is rolled over the band, as indicated in Fgure 1, and the clips 40, such as spring closed clothespins are then applied to the band and the portion of the bag within the band and rolled over the band to firmly secure the bag to the band. These clips do not damage the bags and the rolling of the bags over the band prevents tearing or other injury to the bags.

If desired, the legs l0 and II may be provided with additional holes, as indicated at 4| in Figure 2, below the upper ends of the legs for attachment of the band to the legs at levels below the upper ends of the legs.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
