GOLLAPSIBLE BOX.

FFTQ.

WASHINGTON I. TUTTLE, OF BALTIMORE, MARYLAND.

GOLLAPSIBLE BOX.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed January 14, 1907. Serial No. 352,246.

To all whom it may concern:

Be it'known that I, WASHINGTON I. TUT- TLE, a citizen of the United States, residing at Baltimore, Maryland, have invented new and useful Improvements in Collapsible Boxes, of which the following is a specification.

This invention relates to telescoping boxes or rece tacles, which are characterized by. a series oi nesting sections, which, when the box or receptacle is in collapsed or telescoped condition, lie one within the other in close relation, but which may be extended telescopically to increase the capacity of the box; suitable connections being made between the sections so as that they will not become separated from one another.

Broadly considered, telesco ing boxes and receptacles of this general 0 aracter are old, and my present improvements have to do with certam'details ofconstruction of this generally old type, which make for chea ness, strength and durability; which resu t in a receptacle having maximum ca acity in both its colla sod and extended con ition'; and which, eitl fer in extended or collapsed condition, present an interior which is practically free from objectionable crevices and projections, which crevices and projections would not only interfere with the close packing of the receptacle, but would also form catch-alls for the contents of the box.

. In the drawings herewith, in which I have illustrated one embodiment of my invention in order that the samemay be clear to those skilled in the art: Figure 1 is a perspective view of a box constructed in accordance with my invention, the box being shown in that view in collapsed condition with the cover open. Fig. 2 1s a slmilar'vlew showing the 1 box extended and the'cover closed. Fig. 3

is a longitudinal section of the collapsed box. Fig. 4 isa transverse section of the box extended. Fig. 5 is a detail view to show the means for locking the box sections together in collapsed condition.

Referring to the drawings by numerals, corresponding parts being designated by like numbers in the different views, 2 indicates the box bottom, which, as shown in Figs. 3 and 4, has the peripheral head 3 which forms a seat to receive the vertical wall 4 of the box, said bottom 2 and its attached wall 4 forming the lower section of the box. The wal'l'4 is rolled inwardly at its top to form an inwardly projecting bead 5, and preferably the head 5 greater is reinforced by a wire, so as to give stren th and rigidity to the section and reduce likelihood of distortion, which, it is a parent would interfere with, if it did not absolutely prevent, telescoping of the sections.

Sliding within the bottom section first described, is a second section 6, which is pro vided at its bottom with an outwardlyturned, wire-reinforced bead 7; the sections fitting snu ly with their oppositely turned beads 5 an 7 in contact with the proximate walls; and it.will be seen by reference to Fig. 4 that in extended position of the box these beads engage each other and lock the parts against complete separation; but in collapsed condition (see Fig. 3) the section 6 rests upon the bottom 2 of the box.

Reference to Figs. 1 and 3 shows that the bottom section and the section 6 are substantially of the same height, so that when nested, as shown more clearly in Fig. 3, the section 6 projects but little, if any, above the outer or bottom section. Within the section 6 is mounted another section 8, which, in the present embodiment of the invention is shown as the topor last section said section 8 having an outwardly-turned wire-centered bead 9 which engages a similar head 10 turning inwardly at the top of section 6, as clearly shown in Fi 4. The section 8 has secured .thereto, in t e three-section ty e of receptacle herein shown, the cover 11 w 'ch is hinged at 12 to the side wall of section 8, the said section 8 being beaded at 13 near the top to give it rigidity and form the cover bead, and preferably the upper edge of the section is turned injas at 14 to give greater strength and a neat finish to the top. The cover 11 is provided with a projecting button 15 which is secured by a washer 16 on the underside of the cover,

which button 15 is designed to receive a latch 17 secured to the section 8 by means of a U- shaped fastener 18, the ends of 'WhlCh pass through slits in the front of the section andare turned down as shown clearly in Fi 4. The said top section 8' carries also the bail 19 which is secured to the ends of the section by means of cars 20 the side limbs 21 of which enter slits in the walls of section 8 and are bent down so as to lock the cars 20 firmly in place. The said cars 20 preferably stand away at their bail-engaging ends from the .walls of the box, (see Fig. 3), so as to give clearance for the handle or bail 19 and permit it to swing freely out'of contact with the box, said bail 19 being of such size as that it will fall outside of the box as shown in Fig. 1 and be out of the way, either'for convenience in packing the boxes or to permit free opening of the cover 11. The said ears 20 have their lower ends 22 sprung outwardly, as shown, so that when the box is in collapsed condition the ends or links will enter between the sections 4 and 6. (see Fig. 3) this entrance of the ends 22 being automatically effected when the sections are telescoped together. Each downwardly projecting end 22 has a small teat or projection 23, referably stamped up from'the metal, whic engages the rib 5 on the lower or bottom section to 1 lock the parts together in collapsed position;

' eflective loc "the natural elasticity of the adjacent walls of the sections clamping the locking end 22 sufficiently to effect this locked condition, but not reventing the ehd 22 from snapping into anc out-of place. This feature is of considerable im ortance as it gives a simple and king device to hold the arts in collapsed condition, if it should so appen that the frictional engagement of the secv tions was insufficient and this feature is of heads 9 and 10, is free to telescope within the sections below it until it rests upon the bottom 2 of the lower section. The cover section 8, furthermore, is so proportioned relative to the other sectionsof which the box is made, that, when the box is in collapsed condition, it extends above the other sections, thereby giving clearance for the ears, bail, and cover so that they will not interfere with the collapsing of the box by striking the lower sections, and also permits the use of the downwardly extending locking end of the ear. It will be seen that in the collapsed condition of the receptacle the interior surface of the box is unbroken, its area being defined by the bottom, the cover, and the surrounding side walls of the upper section 8, only, without projections or crevices at any point on its interior to collect and retain the material packed therein. This absence of crevices and catch-alls is partly due to the fact that the sections are so connected to each other that there are no interior upwardly-facing beads,ledges, orprotuberances to catch the material which may be placed in the box, for it will be observed that since each of the several sections telescope Within the adjacent lower section and have at their lower ends outwardly rojecting beads, it is possible to provide in 'vidual sections with smooth interior faces, and have the jointsv between the several sections for downwardly facing ledges, so that material can find no lodging place on the interior of the box either when it is in extended or collapsed condition. When the box is in collapsed condition as shown in Fig. 3, and as described above, this condition of an absolutely smoot hinterior, without break or crevice, is due to the fact that the sections may telescope without hindrance until they rest upon and are supported by the bottom 2 of thebottom section, and since there is nothing to prevent close contact between the lower edge of the cover section 8 and the bottom of the lower section, obviously no crevice or opening exists through which the material can creep, and an absolutely smooth interior is secured. Furthermore, by thus constructing the upper section and assembling it with the other sections as described, the walls of the section 6 and bottom section can never come in contact with the material initiall packed into the box, which is usuall to acco, (it being understood that this ox is primarily intended, although not restricted, for use as an original package in which tobacco issold, the box, after the contents originally placed therein have been used, havin been found very serviceable as an extens1on lunch box or kit) and these side walls are thus kept sweet and clean and uncontaminated by the contents of the original packa e, so that after the tobacco has been use it becomes necessary only to clean the inner wall of the top section 8 and the bottom 2 to fit the box for use as a lunch kit or receptacle.

It will be understood, of course, that such changes in form and construction as involve merely the work of the designer and mechanician may be made without de arting from the s irit of my invention, and I 'do not,

there ore, limit myself to the details of construction shown and described except in so far as I am limited by the prior art to which this invention belongs.

Having fully disclosed my invention, I claim:

1. In a collapsible box and in combination; a bottom section, one or more intermediate sections, an uppersection of greater height than the other said sections which projects above the tops of the other sections when the box is in collapsed condition to form a lid and hail carrying extension, anda lid and hail secured to the extended portion of said upper section.
