UNITED STATES MICHAEL JOSEPH H. CUNNINGHAM, OF LYNN, MASSACHUSETTS.

BAG, SA'I'OI-IEL, AND SIMILAR RECEPTACLE.

Specification of Letters Patent.

Application filed March 6, 1909.

Patented May 6, 1913.

Serial No. 481,836.

To all whom it may concern of Essex, in the State of Massachusetts, have invented certain Improvements in Bags, Satchels, and Similar Receptacles, of which the following is a specification.

My invention relates to the,construction of bags, Satchels and similar receptacles having a variable carrying capacity which can be enlarged or reduced in size and shall be cheap and simple to manufacture.

My invention therefore resides in the construction necessary to telescope a bag, and means for looking it in position.

In carrying out my invention, 1 provide an internal structure for holding the flexible body of the bag distended, and in order to permit the bag to be enlarged or retracted to maximum or minimum size, this internal structure is made of two sections, one section being in the form of a frame or box of fixed dimensions arranged in the bottom of the bag, and the other of variable dimensions or expandible and contractible so that it can slip into or around the box section in telescoping relation thereto. The advantage in having the upper contractible and expansible section of variable dimensions is that when the bag is opened to its full extent, the walls of the bag will be perfectly fiat so as to have the appearance somewhat of a suit case and yet the bag will be held rigidly dist-ended. I

construction showing the top portion of the bag, telescoping outside the lower portion in contradistinct-ion to the construction shown in Fig. 1.

Referring to the drawings in detail; 1 represents a bag or satchel made of any flexible material, preferably of soft leather, having a frame 2 and 3, secured thereto, which can be opened or closed in relation to each other and serve as a suitable access to the bag, 1. Secured to the frame 2 is a suitable carrying handle 4, of well known construction. The leather or flexible material is carried under the bottom, 5, of the bag, 1, and is adapted to receive a box, 6, having U-shaped ends. The box, 6, is rigidly secured to the bag, 1, by any suitable means.

Secured to the bag, 1, is a movable frame,

7, consisting of vertical arms 8 and 9, to which are secured four U-shaped strips, 10, 11, 12, and 13 connected together by means of cross levers 14, 15, 16 and 17, these levers are pivotally secured together as shown at 18 and 19. The other extremities of the said levers are also pivoted to the U-shaped strips as shown at 21 and 22. By this construct-ion, a flexibility is given to the frame 7, which facilitates in operation. When the bag is in an extended position as shown in Fig. 3, the frame 7 is identical in shape to the box 6 hereinbefore mentioned, permitting straight contour of the said bag. The U-shaped strips are constantly forced outward by means of springs 25 and 26, the springs also tend to force the telescoped portions together, partially retaining them in position, as shown in Fig. 1. The frame 7 also cares for the loose ortion when the bag is in a telescoped position. The upper portion 27 and 28 of the vertical arms 8 and 9 extend upwardly and are adapted to receive the latches 29 and 30 respectively and are rigidly secured thereto by means of rivets. The latches 29 and 30 cooperate with the catches 31 and 32 which are rigidly secured to the box 6 by any suitable means, preferably rivets.

The frame 7 is suitably secured to the bag 1 by means of the rivets which hold the latches 29 and 30 in position, and also at the upper U-shaped strips 10 and 12; by so doing the lower strips 11 and 13 are free from the bag allowing the loose flexible material to adjust itself to conditions when the bag is in a telescoped position as shown in Figs. 1 and 2.

A suitable lining is provided and is indicated by dotted lines in Fig. 3.

My alternative construction shown in Fig. 4 consists in the upper portion of the bag telescoping outside the lower portion by means of the same mechanism described above, it is held in position by means of a suitable catch and latch 40 and 41 respectively. In Fig. 4 the catch and latch extend below the bottom of the bag, which would hinder the bag from resting on a flat surface and to obviate this I have provided specially constructed feet 42 which extend below the catch and latch 40 and 41 respectively, thereby eliminating any adverse results from the same. a

In operation the bag is held in a telescoped position by means of the catches and latches 29, 30, 31 and 32 respectively. The frame 7 assists in the same by means of the friction caused by the spring 25 and 26 forcing it against the flexible material and box 6. When the operator wishes to extend the bag the latches 29 and 30 are released from the catches 31 and 32, at this point the bag is pulled out the full length and is retained in a straight line in relation to the box 6, by means of the frame 7. To reset the bag the operator takes hold of the bag in the location of the frame 7 forcing it inwardly against the springs 25 and 26, any downward movement of the frame 7 with the bag attached thereto, will cause it to be forced into the box or frame 6, carrying with it the loose leather or flexible material, until it is in the location when the latches 29 and 30 ride down the inclined surface of the catches 31 and 32 and snap into position, thereby causing the upper and lower portions of the bag to be securely locked together reducing the same.

In accordance with the provisions of the patent statutes, I have described the principles of operation of my invention together with the apparatus which I now consider to be the best embodiment thereof; and I want to have it understood that the apparatus shown is only illustrative and that my invention can be carried out by other means.

Having thus described the principles of my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination of a flexible bag, with a pair of devices secured respectively to the upper and lower portions of the bag for holding the walls thereof distended and capable of telescoping movement, one of the devices being of fixed dimensions and the other of variable dimensions to permit of the telescoping of the devices.

2 The combination of a bag capable of being increased or reduced in size, with an internal structure for holding the walls of the bag distended, said structure consisting of a box secured in the bottom of the bag, and a frame arranged in the upper portion of the bag and capable of expanding and contracting both longitudinally and transversely to permit of telescoping of the frame and box.

3. The combination of a bag, a box arranged in the bottom of the bag and having an open top, a frame disposed in the bag above the box to cooperate with the latter for holding the walls of the bag distended and each wall flat, said frame being contractible and expandible in a horizontal plane to permit the box and frame to telescope, and means exterior to the bag andv fastened thereon for holding the frame and box in telescoping relation.

4. The combination of a bag, with upper and lower frames secured respectively to the upper and lower portions of the bag and arranged to telescope, one frame consisting of oppositely-disposed U-shaped members and yielding means operatively connected with both members for permitting them to move toward or away from each other for changing the horizontal dimensions of such frame to permit the frames to telescope.

The combination of a bag, with tele scoping frames mounted within the bag and forming supports for the walls thereof to prevent inward collapsing, one frame being expandible and contractible and consisting of sets of oppositely-disposed bowed members, means connecting and holding the members of each set in spaced relation, and means for connecting the inner ends of the members of one set with the members of the opposite set for permitting the frame to expand or contract.

6. The combination of a bag, with telescoping frames mounted therein for holding the walls of the bag distended, one frame being of fixed dimensions and the other being of variable dimensions, said other frame consisting of sets of oppositely-dlsposed horizontal U-shaped members, crossed links pivotally connecting the members of one set with those of the other, and means operating on the links to yieldingly force the sets of members apart and hold the frame expanded.

7. The combination of a bag, with separate frames arranged therein for holding the walls of the bag distended, one frame comprising two oppositely-disposed U- shaped sections capable of yielding to permit the bag to expand and contract transversely, and yielding means disposed be tween the. sections to permit the bagto be contracted longitudinally, said means tending to hold the bag expanded longitudinally.

8. The combination of a bag capable of bag for imparting permanent rigidity to the walls thereof adjacent the bottom, and

means telescopically related to the firstoutward movement to vary in horizontal dimentioned means and attached to the upper mensions for telescoping with respect to the portion of the bag to prevent collapsing of first-mentioned means.
