BAG-FRAM E.

SPECIFICATION forming part Of Letters Patent No. 448,139, dated March 10, 1891.

Application filed December 23, 1890. gerial No. 375,567. (No model.)

To whom it may concern.-

Be it known that BENJAMIN MAYER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in BagFrames, which improvement is fully set forth in the following Specification and accompanying drawings.

My invention consists of a bag or satchel frame having a spring connected therewith, substantially as described, whereby said frame may be automatically opened and held opened, said spring being mounted on the pivots of the frame and having its ends hearing against the frame, thus providing an inexpensive and practical device for the purpose intended.

It further consists of the combination of parts hereinafter described.

Figure 1 represents a perspective view of a bag having a frame embodying my invention. Fig. 2 thereof. Fig. 3 represents a vertical section of a portion at a right angle to Fig. 2. Fig. 4 represents a top view ofa portion, showing the ends of the spring concealed.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a bag, and B designates the frame thereof, said parts, excepting the feature of my invention applied thereto, being of usual construction.

0 designates the pivot of the jaws of the frame, the same having connected therewith the wire springs D, a portion of each of which is of the form of a coil E, which is fitted on the pivot, and the ends F of the springs project from the coil in opposite directions and bear upon the jaws of the frame, itbeing seen that when the jaws are closed the springs exert pressure against the same in such manner that when the fastenings are released said jaws are forced open or apart and held open, as will be seen in Fig. 1. IVhen the jaws are closed, the ends F ride freely on the jaws, while the coils are contracted, so that the springs exert the proper pressure on the jaws, whereby when the latter are released they are thrown open, as previously stated.

represents a vertical section In order to provide stability for the ends of the springs and increase the bearing-surface thereof, said ends are bentlaterally, forming lips G, which areincontact with the jaws, as shown in the several figures. The said lips G also present a rounded surface to the jaws, thus lessening the liability of said ends being caught against the said jaws. The springs are prevented from displacement by means of Washers or heads H, which are placed on the inner ends of the pivots and riveted or otherwise secured thereto, it being noticed that said pivots are made sufficiently long to connect the jaws, sustain the springs, and hold the heads. It will also be noticed that both ends F extend from the same side of the coil of the spring at the outer sides of the frame, so that the lines of their contact with the jaws are substantially in the same plane, whereby there will be no liability of the ends leaving their seats on the jaws and entering the bag, the injurious effect of which would be evident.

In Fig. 4 I show the ends of the spring covered by plates F, said plates forming with the jaws closed chambers, the same concealing said ends, without, however, interfering with the freedom of motion thereof. As said ends of the spring are thus guarded, they are prevented from catching the contents of the bag or being caught by the same. The plates F are removed in Figs. 2 and 3 and the right side of Fig. 1.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A bag-frame having pivoted jaws, a coiled spring bearing against the same, having its ends projecting in opposite directions, and covering-plates secured to said jaws, forming a chamber within which said ends are located and have their play, said parts being combined substantially as described.

BENJAMIN MAYER.
