BAG HOLDER AND OPENER.

Specification of Letters Patent.

Patented Nov. 21, 1916.

To all whom it may concern:

Be it known that I, HIYozo KAWATE, a subject of the Emperor of Japan, and resident of Seattle, King county,'lVashington, have invented certain new and useful Improvements in Bag Holders and Openers, of which the following is a specification.

My invention relates to paper bag holders and openers, and consists of certain novel constructions and combinations of parts which will be hereinafter described and particularly pointed out in the claims.

The object of my invention is to provide a device which is cheap in cost and which may be conveniently and quickly filled with a bundle of bags which are held thereby until wanted for use and which will cause the opening of the bag when it is withdrawn from the pile.

In the accompanying drawing I have shown my invention in the form which is now preferred by me.

Figure 1 is a face view, Fig. 2 an edge view, and Fig. 3 an end view of the device in its empty or closed position. Fig. 4 is an edge view of the device distended for the insertion of sacks. Fig. 5 is a detail showing a type of catch which may be used. Fig. 6 is a view of one end of the device with a few sacks in place illustrating the operation of the device. Fig. 7 is a top view, and Fig. 8 a side view of a modified construction with a number of sacks in place.

My invention is based upon the utilization of a helically coiled spring or springs as the bag holding agency. The bottom edges of the bag are inserted between the coils of the spring while the latter is distended, and they are then yieldingly held between the coils when the spring contracts.

The common square bottom paper bag as it is received by the trade, is folded so that the bottom lies alongside the body. It is so made that one side, at its mouth, is slightly longer than the other, the short side being that one which connects directly with that edge of the bottom which is outermost when the bag is folded.

If a helically coiled spring, as 1, which has been coiled close, be distended, it makes an opening between each coil, which opening is adapted to receive the edge of a folded bag, and it will hold the bag securely if it is allowed to collapse or retract while the bag isbetween the coils. It is possible to quickly place a large number of bags in this way. If a bag, so held, is engaged by the mouth end of the side which is not held between the coils of the spring and pulled, itwill first be opened, as shown in Figs. 6 and 8, and then be withdrawn. It is thus in condition for receiving the goods which are to be placed tllGIElIlh The whole oper' atlon is natural, quickly done and the opening is automatic.

The device as shown in Figs. 1 to 6 has a main frame board 2 and two bars 8 sliding in guides which are shown as holes bored in the board 2. At one end of the frame is a lateral arm or board 20 to which one end of springs 1 is secured and at the other end is a hanger plate 21. The outer ends of rods or bars 3 are connected by an off-set cross bar 30, to which the other ends of the spring are connected. The springs lie close to the surface of the board 2.

The board 2 may be provided with catches for retaining the rods 3 when drawn out and while the bags are being placed therein. The catches herein shown consist of levers 4t pivoted at 41 and having a pin 12 connected thereto and lying in a lateral bore which intersects the bore or guideway 00' copied by the rod 3. These rods 3 may be provided with notches or apertures in which the pins 42 may engage, but as herein shown, the pins engage the inner ends of the rods, and thereby prevent retraction of the springs 1. The pins 12 are pressed inward by springs 10, to engage the rods 30.

In the modified construction shown in Figs. 7 and 8, pairs of links or crank arms 6 are connected by cross bars 5, and are pivoted at 60 to frame bars 7. The springs 1 are shown as connected to the cross bars 5. Without any bags in place, the parts would assume the position shown in these figures by dotted lines. To insert the bags, the arms 6 are turned away from each other to distend the springs as is shown in dotand-dash lines. The device may be suspended, as by cords 70, in any convenient place.

What I claim as my invention and desire to secure by Letters Patent is:

1. A bag holder and opener comprising a frame, a helically coiled spring supported thereon, means for distending the spring to insert the bag ends between the coils thereof, and automatically-engaging means for holding said sprlng distended.

2. A bag holder and opener comprising a springs connecting said bars, and means for supporting said bars to permit their movement toward and from each other, said means limiting their inorement toward each other.

4i. A bag holder and opener comprising a frame board having guiding holes bored therein, bars slidable therein and connected to move together, helically coiled springs secured at one end to saidbars and at their other end tosaid frame board, and automatically engaging means for holding said spring in distended position.

5. A bag holder and opener comprising a frame board having guiding holes bored therein, bars slidable therein and connected to move together, and helically coiled springs secured at one end to said bars, at their other end tosaid: frame board, and spring-pressed catches adapted to hold said springs in distended position.

Signed at Seattle, YVashington this 9th dayof November, 19-15.
