SACK HOLDER Filed March 30, 1953 I INVENTOR. '1 fez/7y Z. Weak/cell? nited States Patent SACK HOLDER Harry L. Westervelt, La Grange, Ill. Application March 30, 1953, Serial No. 345,326 4 Claims. (Cl. 248-97) This invention relates o a device for holding a sack open and upright to facilitate filling the sack, and has proved device of this kind.

It is a main object of the invention to provide a simple without sacrificing ruggedness and quality.

Further objects of the invention not tioned here will be apparent from the detailed description and claims which follow, reference being had to the accompanying drawings in which a preferred embodiment of the invention is shown by way of example and in which:

Fig. 1 is a front elevational view of Fig. 2 is a plan view of the device;

Fig. 3 is an end elevational view of the device;

Fig. 4 is a cross sectional view through one of the lugs on the device, showing also a sack registered therewith; and

Fig. 5 is a view similar to Fig. 4, showing the sack retaining means in operated position.

Farmers, feed dealers, and many others, have occasion frequently to fill sacks,

the device;

to manipulate a scoop to fill the sack.

The present invention provides a device which will hold the sack open so that the workman will have both hands free to manipulate a scoop or other tool for filling the sack.

sacks are now in very common use. Furthermore, the prior art devices of which I am aware, were either permanently attached to an upright member, such as a Wall or post, or were of such heavy construction as to make moving the device from place to place extremely difiicult.

The present invention in its lightweight sack holding device capable of being used about by one person easily, as required in the normal usage of a device of this kind.

Grain sacks, gunny sacks, and the like, come in a number of different heights and girths, and to be able device of the present invention is Referring now to the bottom of the device sufiiciently to prevent it from being top heavy and apt to be tipped over when in use.

Mounted upon the tubular member 9 by a pivotal connection is a latch consisting of a bar 14 that has in its lower edge serrations or teeth 15 adapted to be registered with a keeper plate 16 fixed upon the bar 10. A spring 17 extending between the member 9 and the bar 14 is tensioned to hold the teeth 15 in engagement Aswill be seen in Fig. 2, the arcuate portions 11 and Id open in a direction facing each other and each is provided with a pair of lugs 20 and 21 secured to the, arcuate wardly and outwardly from the lug. a

As will be seen in Figs. 2 and 4, when a sack is registered the ar'cuate member supportingv the lug. thereby to securely.

bind the sack to the device.

After the sack is thus secured in place, the pivoted upright, consisting'of members 4 and 10, may be pushed outwardly far enough to draw the top edge of the sack taut so as to make it easy to fill the sack with a scoop or similar device.

In the case of sacks of exceedingly large girth, it is advantageous to provide adjustment of the relatively fixed upright of the device so as to keep the sack centered or substantially centered therein. To this end, the bracket 30, by which the brace bar 6 is secured to the base, may be moved to any one of a number of positions, one of which is shown in dotted lines in Fig. 1. This eifects movement of the fixed upright outwardly so as to accommodate the device to the greater girth of the sack. The device may be adjusted to the height of the sack by loosening wing nuts 13 and pushing the upper tubular members 9 and 10 downwardly from the position shown. Fixed to the lower ends of members 9 and 10 are plates 31 which extend outwardly therefrom into the space between tubular members 3 and 4 respectively, and angles 32 fixed thereto. These plates 31 run in a groove and prevent wobble between the members thereby aiding in maintaining the uprights rigid in all positions.

The resilient clamping members must be sturdy and sufficiently elastic to permit them to be stretched over the lugs and the portion of the sack registered therewith a number of times without breaking. I have found that when cut from India rubber of good grade, the lugs 24 have long life and maintain suflicient tension on the sack to securely bind it to the device. When it is necessary to replace a resilient member 24, screws 23 and clamping plate 22 are removed and a new member inserted in a convenient manner.

When composed of thin wall metallic tubing, such as thin wall conduit, the uprights of my improved device are sufficiently sturdy to withstand the hard usage likely to be encountered and at the same time are light enough so that the device is not too heavy to be easily moved by one person. able hard wood, the device does not easily tip over, and since the bag rests upon this baseboard the tendency for the device to tip is lessened by the weight of the contents in the bag.

While I have chosen to show my invention by illustratingand describing a preferred embodiment of it, I

have done so by way of example only, as there are many 4 modifications and adaptations which can be made by one skilled in the art within the teachings of the invention. Having thus complied with the statutes and shown and With the baseboard composed of a suitdescribed a preferred embodiment of the invention, what I consider new Patent is pointed out in the appended claims.
