WVILLIAMS. SCALES, OF EVERETT, MASSACHUSETTS.

COLLAPSIBLE TUBE.

SPECIFICATION forming part of Letters Patent No. 624,649, dated May 9, 1899.

Application filed January 7, 1899.

To all whmn it may concern.-

Be it known that I, WVILLIAM S. SCALES, .of Everett, county of Middlesex, State of Massachusetts, have invented an Improvement in Collapsible Tubes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve the construction of collapsible tubes; and it consists, essentially, in a collapsible tubular body crimped at one end to fold inward toward the middle of the tube and a head comprising two plates, between which said crimped end of the tubular body is clamped. The head will have an opening through it as an outlet, which may be closed by a cap or stopper. As a means of connecting said plates together to clamp the end of the tubular body flanges may be formed on a neck which will receive said plates between them, and said neck will have a hole through it which will serve as an outlet for the tube.

Figure 1 shows in vertical section a sufficientportion of a collapsible tube embodying this invention to illustrate the same, the parts being in assembled position but not clamped together; Fig. 2, a similar vertical section showing the parts clamped together, and Figs.

3 and 4 details showing the crimped end portion of the tubular body.

The collapsible tubular body is herein composed of an inner tube a and an outer tube 1), said tubes being laid one upon the other, although so far as my invention is concerned said tubular body may be composed of one or more tubes, as may be desired.

One end of the tubular body, whether composed of one or more tubes, is crimped for a short distance-i. e., it may be first scored, as at a and thereafter plaited or folded to close inward and partially close the end of the tubular body, and said plaited or folded end portion I herein call a crimped end.

In Figs. 3 and 4: the end portion of the tubular body is shown as crimped. The head is composed of two plates 0 and d, preferably made circular and of any suitable size, and said plates are also preferably made of metal and dished, and the crimped end portion of the tubular bodyis placed between said plates 0 and cl, as represented in Fig. 1.

A tubular neck 6, preferably made of soft Serial No. 701,491. (No model.)

metal, is provided, which is inserted through central holes formed in the plates 0 and d, and said neck c has formed at its lower end a flange e, upon which the bottom plate 0 rests, and said neck 6 is also provided with a shoulder 0 which when compressed by suitable dies provided for the purpose will project laterally and from a flange which may be pressed down onto or impinged upon the uppermost plate (Z of the pair of plates, and thereby firmly and securely clamp and hold said pair of plates together with the crimped end portion of the tubular body between them. The collapsible tubular body will thus be securely and tightly connected with the neck.

A closing-cap f will be provided, which is herein shown as provided with an internal screw-thread which is turned onto a screwthreaded portion on the neck e, although said closing-cap f may be otherwise constructed or a stopper used as a means of closing the tube.

While I have hereinshown the two plates c and d as clamped and held together by flanges on the neck 6, I do not desire to thus limit my invention, as said plates may be oth erwise connected or clamped together, so as to firmly hold the end portion of the tubular body between them.

The crimped end portion of the collapsible tubular body being composed of the same ma;

terial as said collapsible body, will of course,

yield or collapse, notwithstanding it is crimped, unless reinforced or stiffened, and it is desired that they completed collapsible tube shall have astiffened or unyieldinghead, and consequently the two plates 0 andd are made of metal and serve to reinforce or stifien the head of the tube in addition to serving as a clamp for engaging and holding the upper end of the tubular body, and to furthermore insure proper rigidity for the head one of the two plates, preferably the bottom plate a, will be made of a diameter approximately equal to the internal diameter of the tubular body.

I claim- 1. In a collapsible tube, a collapsible tubular body having a crimped end, a head comprising two plates between which said crimped end is clamped, the bottom plate being approximately the internal diameter of the tubular body and a tubular neck having flanges for holding said plates securely together, sub- I said plates securely together, substantially as described.

In a collapsible tube, a collapsible tubular body, and a head comprising vtwo dished plates between which one end of said tubular body is clamped, and a tubular neck having a flange and a compressible shoulder e which constitute means for securing said neck to the plates and also means for holding said plates together to clamp and hold the tubular body, substantially as described.

4. In a collapsible tube, a collapsible tubular body having a crimped end, and a head comprising two plates between which said crim-ped end of the tubular body is clamped, the bottom plate being approximately the internal diameter of said tubular body, substantially as described.

5. In a collapsible tube, a crimped-top collapsible tubular body, a head comprising two plates between which said crimped top is clamped which serves also to reinforce and stiffen said crimped top, to provide an unyielding head for the tube, a tubular neck and means for connecting said neck to'the I plates which also holds said plates securely together, substantially as described.

6. In a collapsible tube, a crimped-top collapsible tubular body composed of two layers of material laid one upon the other, both layers being crimped, a head comprising two plates between which said crimped end portion of thebody is clamped, and a tubular neck having flanges for securing said neck to the plates and also for holding said plates Securely together to clamp the crimped top of the tube, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILLIAM S. SCALES.
