To all whom it may concern:

Be it known that we, Karl Kruppa and Oscar Lehrer, citizens of the United States, residing at Fort Reno, in the county of Cana5 dian and Territory of Oklahoma, have invented certain new and useful Improvements in Enlargeable Telescopic Cases or TravelingBags ; and we do declare the following to be a full, clear, and exact description of the into vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which forma part of 15 this specification.

Our invention relates to traveling bags and cases, and especially to that class of bags known in the art as “telescopic,” in that theyare composed of two separable parts, each slid2o able on the other, whereby the bag or case is closed and its size· increased or diminished perpendicularly at will.

It is the object of our invention to provide and produce a case or bag that can be auto25 matically adjusted and its size extended both longitudinally and laterally with equal facility and ease as it could heretofore be extended perpendicularly, and thus to. provide a case enlargeable into three or more sizes, ac30 cording as the principle might have been extended in its construction, as occasion, should arise for its use by the owner, avoiding the necessity heretofore existing of keeping a number of different-sized valises, traveling35 bags, or cases to carry larger or smaller quantities of articles compactly for· the purposes of each particular trip, and also providing a case that could be turned by unfolding into a “full-dress-suit case” with the same facil40 ity and ease that it could be folded into an ordinary-sized traveling-bag, thus saving a great expense to the general public and supplying a long-felt want. We attain these objects and ends by the mechanism illustrated 45 in the accompanying drawings, in which—

Figure 1 is a perspective view of our complete device. Fig. 2 is a transverse section of our complete device. Fig. 3 is a longitudinal section showing it with one extension 50 extended. Fig. 4 is a longitudinal section showing it with two extensions extended.

Fig. 5 is a perspective view of the lower part of our receptacle, showing the manner of folding. Fig. 6 is a perspective view of our improved hook and catch. Fig. 7 is a detailed 55 view of our folding triangles.

Referring to said drawings by letter, A denotes the top half or section of our complete case.

B denotes the lower half-section of our com- 60 plete case.

G denotes our original improved adjustable handle complete; D, the bottom section of handle, which can be constructed of wood or metal and is made in a solid piece with a slot 65 through same extending along its center sufficiently far to permit adjustment to all extensions of case orbag; E, thumb-bolt to pass through top of case and bottom section of handle D and secure same to case, which 70 when loosened by turning the top permits the adjustment of the handle to any longitudinal extension of the case by sliding the handle and also by revolving around said thumbbolt to permit adjusting to any lateral, exten- 75' sion, and by buckling the short strap F into the ring G at side of case form a perfectly-secured handle when so laterally extended. II is the top section of said handle.and is a leather strap or other flexible material fastened at 80 each end of bottom section D with rivets or bolts on either side of slot I, through which leather straps J J pass and are buckled together to bind and hold the two halves or sections of the complete receptacle together 85 and also to support the handle.

K K K K are'.folds in both sections of case when folded to.its smallest size; likkk, same folds when enlarged to second size; L, our improved hook and catch, adapted to hold 90 folds in place and give strength and stiffness to the sides of the. receptacle; Μ Μ Μ M, our original triangles, constructed of the same material that the sides of the case are constructed of and of like weight and thickness, 95 which may be either of leather, wood, or pasteboard or metal, covered solidly with leather, cloth, or other flexible material, bound around the edges with steel or other metal rods or wires underneath the’ outside 100 cover to give strength and stiffness to both the sides and triangles; N N N N, rows of g 606,221 stitching between the four triangles through the leather, cloth, or other material 'with which they are covered, (and with which the sides and bottom of the receptacle are cov5 ered,) forming a strong durable flexible hinge between the adjoining points of said triangles (shown in Fig. 7) when folding or unfolding the sections of said complete case to enlarge or diminish the same; 0 0, leather io protectors stitched on the outside of covering to triangles to prevent the triangle - points from puncturing the covers when folded and to reinforce same; P P, like leather protectors to reinforce corners of triangles where they 15 are joined to the main body of case-sections by stitching, as shown in the drawings. Said protectors are sewed through and through the material as the 0 0 protectors above described; Q, adjoining points of the inside of 20 the triangles and stitchings; r, Fig. 7, our four triangular pieces, which when covered and joined together by stitching, as above described, form the folding and enlarging features of our invention.

. S' S³, S^s, and S⁴are the spaces between the adjoining sides of our complete set of triangles before they are covered over with leather, cloth, or other material and stitched together, as above described, and each space is suffi30 ciently larger than the other to fold up smoothly when the case is diminished, space S' being double the width of space S^s, and so on; Z, metal rods or wires extending around top of case under the cloth or leather cover35 ing which forms the outside to strengthen and stiffen the same; t, similar metal rods to support corners perpendicularly underneath cover, as above set forth.

Our case is constructed, as above set forth, 40 of pasteboard, cardboard, wood, or metal or other stiff material covered with leather, cloth, or other flexible material, reinforced and strengthened with wire or metal rods around the top, bottom, and up the corners when de45 sired, with our original complete handle constructed, as heretofore set out, of wood, metal, and leather, adjustable to all extensions of case automatically. The case and all of its parts may be made as light or as heavy as 50 desired aud may haye as many trays or inner receptacles as desired constructed on the same principles as the lower section of case, only smaller to fit inside thereof, with our triangular folding arrangement applied to the construction and operation of said trays or inner 55 receptacles, so that they may be automatically enlarged or diminished as.the case is so enlarged or diminished, making a complete enlargeable telescopic case and inner receptacles more perfect and complete in all its de- 60 tails than any other case yet designed.
