SPECIFICATION forming part of Letters Patent No. 495,151, dated'April 11, 1893'.

Application filed May 31,1892. Serial No. 435,092. (No model.)

To all whom it may concern,-

Be it known that I, EMMANUEL DESMARAIS, of Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Extension Hand- Bags, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specifica- Figure l is a'perspective view showing my improved bag closed in its most compact form; Fig. 2 a like view showing the bag extended longitudinally; Fig. 3 an end elevation showing the inner side of one of the body members; Fig. gt a like view showing the extension flaps turned out; and Fig. 5 a perspective view of the part shown in Fig. 4.

Like letters of reference indicate corresponding parts in the different figures of the drawings. I

My invention relates especially to extension hand-bags or valises; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following In the drawings, A B represent the body members of the bag and O D the cover members. These members are all constructed of the same general form consisting of arectangular box each having an open end, 61, as best shown in Fig. 5. Each member has its outer corners bound or reinforced at, f. The body member, A, is slightly greater in width so that its companion member, B, will telescope therein when the open ends, cl, of said members are registered. Each body member has a flap, g, 9 connected to the upper edges of its sides and end by a flexible joint, h, said flaps being adapted to be turned inwardly into said members, as shown in Fig. 3. When turned outward, as in Fig. 4, to extend the bag body vertically they are secured in alignment respectively with the sides and ends by overlap pieces, 1', fastened to the tlap,g and having a button-hole for receiving a button, j, on theadjacent side flaps.

The cover members,0 D, are p of the same construction as the body members without the flaps, g, 9 The member, D, telescopes into the member, 0, longitudinally and both are of such size that the bodymembers can telescope vertically therein. Said covers have strap loops, t, for a strap, o, having a handle, to, by which the members are held together. Straps, 0c, encircling said members laterally are also employed.

In use when only a small amount is to be carried in the bag the flaps, g, 9 are turned inward and the body and cover members telescoped until the members, B D, are practically covered by their companions. The whole is then secured together by the straps, o, 00, forming a compact bundle as shown in Fig. 1. The valise may readily be elongated by drawing the members, B D, outward from the members, A C, respectively to any desired length so long as the walls of companion members at their open ends slightly overlap. The

whole is secured by'the straps as before' As the members are ordinarily forced or closed tightly against the contents of the bag such contents prevent the same breaking or the members separatingat the joint. As an additional precaution the members, A D, are respectively constructed slightly longer than their companion members, 0 B, as shown in Fig. 2, forming an overlap joint which will not break readily particularly when the central strap, 00, is employed.- The cover members may be moved vertically on the body to enlarge the bag in this direction in the same manner as the ordinary extension bag of this class. And as a further provision I employ the flaps, g, 9 the use of which in manner above described enables the device to be changed in capacity from the small compact hand-bag of Fig. 1 to a large valise or trunk.

Having thus explained my invention, what I claim is- 1. An extension bag comprising two independen t longitudinally telescoping body members, and two independent longitudinally telescoping cover members adapted to receive and telescope vertically on said body members,

provided with folding extension flaps, g, 9 at their upper edges in combination with the telescoping cover members,C, D,-and-the strap,

1), for securing them on said body members substantially as specified.

4. In an extension bag the telescoping body members, A, B, having vertically folding oxtension flaps, g, 9 the fastening strap, 1;, and buttomj, for securing the flap together in vertical position; the telescoping cover members, C, D, adapted to receive said body members; and the straps, v, 00, for securing said members together, all being combined and arranged to operate substantially as set forth.
