' 1 Claim. (01. 150-10) This invention relates to a bag frame and has for one of its objects to provide a device which will snap closed when moved into a position approximating its closed position and, due to some I resiliency; will tend at all times when closed to maintain a closure of a bag to which it is attached. Another object of the invention is to provide a device which from closed position may be merely pulled open without releasing any locks or latches 1 and which may be closed by externalioppositely directed pressures toward each other and there be maintained closed without the need of any locks or latches.

- Another object of the invention is to utilize a 15 leaf spring for urging the device either to open or closed position, which spring may, if desired, be a part of one of the resilient closure members.

Another object of the invention is to provide two flat ribbon-like resilient members which may be bow outwardly toform an opening or will lie in substantially face-to-face contact to close the opening with suitable devices connecting them at their ends for assisting in such movement from opened or closed position.

With these and other objects in view, the invention consists of certain novel features of cone struction, as will be more fully described, and

particularly pointed out in the-appended claim.

In the use of bag frames it is desirable to proll vide aframe device which may be pulled from its opposite sides to open the bag and by applying positioned beyond a certain angle so that they will snap closed, whereas when moved open beyond a certain position the same spring will cause them to snap open-and thus I am enabled to provide a frame, the flat ribbon-like members of which will bow outwardly to provide for the opening of the bag but which when pushed together will maintain themselves closed by reason of the inherent resiliency and the hinge connection at their ends, and by being flat and in face-to-iace contact will occupy a minimum amount of space; and the following is-a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawing, in designates the pouch material of the bag which is assembled upon a frame by a suitable covering for the frame as at H. The frame is designated generally l2 and, as illustrated perspectively in Fig. 2, is formed of two flat ribbon-like members ll-il' which are identical and usually of spring steel of a temper which will cause the members to have considerable resiliency and berather still.

The members are connected together at their ends by hinges whichconsist of a part it having eyes ll-ii and a part II having eyes W-ll".

It is provided with a cut-out or recess 22 throughwhich the cam or finger II will swing when the two parts are moved relatively about that pintle.

A pair of leaf springs 23 are mounted between the part ll and the end of the member II to extend through the opening I! and be in a position to be engaged by the cam or finger 2|. This cam or ilnger'll is disposed at substantially right angles to the plane or body portion as shown in Fig. 8;-the springs 2I,'which are illustrated as two in number in Figs. 7 and 8, will eng e the finger 2| in a position outwardly of the pintle so as to tend to move the hinge parts ll and it about the pintle toward each other as shown in Fig. 8 so as to tend to close the ends of the memmentary leaf spring, whereas inl ig. 12 I have bers I3 and I3; whereas when the a members l3--l3' are pulled outwardlyso as to bow them into the position shown in Fig. 2, which may be accomplished by a handle 24 on the opposite sides of the bag, then the spring will engage the finger illustrated two such additional supplementary springs, it being understood that any \desired number of leaf springs may be built up to obtain the desired control and will be reversed and the hinge reversed in the 2| on the opposite side 01' the pivot pintle I1 and tend to swing the two hinge parts it and it open or outwardly as shown in Fig. 7.

In Figs. 2, 7 and 8 I have illustrated the members 13-18 as provided with square ends and two leaf springs such as .23'applied in connection with the hinge by being mounted between the: hinge part I4 and the ribbon member I3 and there held in position by the rivets III. In some cases, howeverya single spring 23, such as shown in Fig. 13, will be utilized in a similar manner to that shown in Figs. 2, 7 and 8, whereas in some cases three springs 13, as shown in Fig. 14, will beutilized instead oftwo springs.

The flat ribbon-like members ll-ll' are formed of spring steel stock and in some cases it may be desirable to form such members as shown at 25 in Fig. 9 with the spring tongue 2' formed as one piece with the stock thereof and in such an arrangement no separate spring need be provided, this structure being illustrated in section in Fig. 10. In some cases it may be desirable to supplement the pressure of the spring tongue 26 by an additional spring, such as 23, and in Fig. 11 I have illustrated one such. additional supple- Joining oi the parts together. Where, however. when separate springs are utilized, as 23, it will be immaterial whether the hinges. are symmetrically arranged to each other at the opposite ends of the device.

In each of the showings which I have illustrated, it will be apparent that the ends of the ribbon-like members,'as II, II which are connected together, are spaced by reason oi the construction of the hinge which connects them or by reason of the means which connects the ends to the parts of the hinge. This serves, as will clearly be apparent from Fig. 3, to bow the ribbon members inwardly when in closed position and assist in holding the members in contact at their center portion.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended olaim.

I claim:

A bag frame comprising two resilient fiat ribbon-like members in iace-to-face contact when in closed position, a hinge at each end of the frame, each connecting the adjacent ends of said members together, each hinge being provided with two parts with one part being notched, a

pivot connecting said parts and means including BENJAMIN BLACHER.
