UNITED STATES DANIEL MCKENZIE, OF GUF'LPH, CANADA.

BAG HOLDER.

Application led December 11, 1923.

To LZ1 ywhom t may concer/n:

Be it known that I, DANIEL MoKENzrn, a citizen of Canada, residing at Guelph, in the county of lVellington and Dominion of Canada, have invented new and useful Improvements in Bag Holders, of which the following is a specification.

This invention relates to a sack or bagholder of the type which is intended for sup porting bags in an open position while being filled.

One of its objects is to provide a portable device of this character which is adjustable to fit different-sized bags or like receptacles which vary in depth and width.

Another object of the invention is to provide a simple and inexpensive bag-holder which is strong and durable in construction, and which is easily operated and adjusted.

In the accompanying drawings: Figure 1 is a front view of a bag-holder embodying my invent-ion. Figure 2 is a side view thereof. Figure 3 is a top plan view of the same. Figure 4 is an enlarged fragmentary vertical section on line 4 4, Fig. 2. Figures 5 and 6 are enlarged fragmentary transversel sections on the correspondingly numbered linesin Fig. 4. Figure 7 is a detail perspective view of one of the bag-holding brackets and its supporting arm. Figure 8 is a side elevation of a modified form of the improvement.

Similar characters of reference indicate corresponding parts throughout the several views.

In the embodiment of the invention shown in Figs. 1-7, inclusive, the improved bagholder comprises a portable base or bag-rest 10 to the rear side of which is fastened an upright post or standard 11 seated at its lower end in a socket 12 and held in a ixed position therein by a set screw 13 or other suitable means. If desired, this base may be provided with bolt holes 14, for the purpose of securing it in a permanent position, but it is preferably unfastened, so that the device may be readily carried to any location to suit working conditions.

Adjustably mounted on the standard 11 to slide lengthwise thereof or to turn relatively thereto, are upper and lower heads or guides 15, 16, respectively, which may be provided with cam levers 17, 18, or other appropriate means for locking them in a set position on said standard. To the opposite sides of the lower head 16 are pivoted substantially up- Serail No. 679,920.

right bag-holding arms 19 fulcrumed at 2d" to swing in a vertical plane toward and from each other. The upper ends of these arms are provided with forwardly-extending brackets 21 of substantially hook-shaped form in cross section, with which thel mouth permit said arms to be manually contracted for t-he purpose of applying and removing` the bags to and from the brackets 21. Coil springs 25 housed in openings 26 formed in the head-extensions 28 tend constantly to urge the bag-holding arms outwardly to the corresponding ends of the slots, as shown by full lines in Figs. 1 and 2, in which position the mouth of the bag is stretched taut and held open with its marginal edges engaging the hook-shaped brackets 21.

As shown in Figs. 1 and the top edges 27 of the bag-supporting brackets slope forwardly so as to bring the back end of the bag-mouth higher than its front end. thereby awiiding spillingv material over the backy of the bag during filling operations.

By loosening the cam levers 17, 18, the respective heads 15, 16, together with the bagholdings arms can be raised or lowered on the standard 11 and properly set to suit the length of the bag to be filled, the brackets 21 being so located that the bottom of the bag will rest upon the base 10. In order to contract or expand the arms to suit bags of differentwidths, the upper head 15 is correspondingly raised or lowered relatively to the lower head 16 without changing the height of the arms. Likewise, when it is desired to adjust the device to suit bags which are larger as regards both their depth and width, the lower head is raised toward the relatively fixed upper head 15, which movement results in simultaneously raising and expanding the bag-holding arms to the position shown by dotted lines in Fig. 1.

In applying a bag to the brackets 21, their arms are compressed or drawn toward each other to the position shown by dotted lines in Fig. 4, so as to permit of readily attaching the mouth of the bag to the hooked upper sides of said brackets, whereupon the arms are released and returned to their initial position by the springs 26, thereby tightly and firmly securing the bag in place ready for filling purposes.

' Should it be desired to turn the bag-holding arms and their heads on the standard 11, this can be easily eEected by loosening the cam levers 17 18 and turning the parts to the position desired.

In the modification of the device illustrated in Fig. 8, the base or platform 28 is provided at its rear side with an upright flange 29 from which extend a pair of bearings 30 in which are journaled wheels or rollers 31 for facilitating the moving of the bag-holder 'from one place to another. The standard 3Q, upon which the heads 15, 16 and associated parts are mounted, terminates at its upper end in a rearwardly-extending handle 33. The position of the wheels 31 is such that the plat-form assumes a substantially horizontal position at rest, it being necessary to tilt the device rearwardly when moving it about.

I claim as my invention:

1. A bag-holder, comprising a standard, upper and lower guide heads adjustable lengthwise of said standard, bag holding arms arranged on opposite sides of said standard and ulcrumed at their lower ends on said lower head, the upper ends of said arms being guided directly on said upper head for lateral and longitudinal movement relative thereto, and means within said head and contacting with said arms for extending them to their expanded position.

2. A bag-holder, comprising a standard, upper and lower guide heads adjustable lengthwise of said standard, said upper head having vertical slots near its opposite upper and lower guide heads adjustable lengthwise of said standard, said upper head having substantially horizontal extensions on its opposite sides provided near their outer ends with vertical slots, bag-holding arms arranged on opposite sides of saidy standard and tulcrumed at their lower ends on said lower guide head, the upper ends of said arms passing throughv said slots, and coil springs housed within said extensions and bearing at their outer ends against said arms.

4. A bag-holder, comprising a standard, upper and lower guide heads adjustable lengthwise independently of each other on said standard, means for locking said heads in a set position on the standard, bag-holding arms arranged on opposite sides of-said standard and fulcrumed at their lower ends on said lower guide head, said upper head h aving substantially horizontal extensions on its opposite sides provided near their outer ends with vertical slots, the upper portions of said arms engaging said slots, and resilient means engaging said arms and tend ing normally to move them to their expanded position, said slots being of sufiicient length to permit said arms to be contracted without adjustment ot said guide heads.
