CLOSURE FOR MAILING-T BES.

SPECIFICATION forming part of Letters Patent No. 758,129, dated April 26, 1904.

Application filed August 6, 1903.

T aZZ 1117710721, [25 may concern:

Be it known that I, HARRY D' EL MAR, of New York, in the county of New York and State of for possible mutilationof the contents of the tube.

A particular object of the invention is to provide a closure of the kind set forth that is adjustable, so that it can be made to fit different sizes of tubes and can therefore be made to always provide a solid resistance to the exit of any of the contents of the mailing-tube.

I have illustrated the device in the accom panying drawings, in which Figure 1 is aperspective of a mailing-tubeclosing device being inserted in a tube, the tube being shown in dotted outline. Fig. 2 is a central longitudinal section of Fig. 1, on a slightly-reduced scale, showing the manner of engagement with thetube. Fig. 3 is a perspective of a modified form of Fig. 1; and Figs. 4 and 5 are modifications of Fig. 3, changes being mainly in the shape of the article. r

In the drawings similar reference-numerals indicate corresponding parts in each of the several views.

In the form shown in Fig. 1 I have provided a plate 10, which is furnished on one end with the lip 11, and extending down along this plate from the lip is a slot 12, the material cut out to furnish the slot forming a tongue 13 and having the strips 1d folded over the back to form a way for a strip 15, that is provided on its end with a tongue 16, the tongue 16 be ing on the end opposed to the tongue 13f On the end of the strip is arranged a turnedover portion 17, which is adapted to ride in Serial No. 168,440. (No model.)

perforations from the inside of thetube. The

ends of the tongues are pulled sharply through and then bent-toward the end of the tube and around the end and clamped over on the inside. These closures are preferably made of thin flexible metal, such as brass or tin, andare quickly and easily manipulated and secured in place and removed with despatch.

In Fig. 3 I show a modified form of com struction in which I provide a plate 18, being folded over, as at 19, to form, in conjunction with the turned-over leaves 20, a channel for the two adjustable strips 21. These strips are both adjustable and are provided with the tongues 22, struck up from the body of them and integral therewith, and with the end lips 23, which-are adapted to bear against the inner walls of the tube to furnish means for limiting the outward movement or the extension of the elements of the device. A lip 24 on the inner ends of the strips 21 can be formed so as to limit the outward movement of the sliding strips 21 and also prevent the -accidental withdrawal or the loss and separation of the parts. In this construction I provide an'artiele of the class described that has a larger adjustment, as the arms are adjustable to the body portion.

In Fig. d is a device similar to the one shown in Fig. 3, but with the part. 19 bent back over upon itself to stiffen the plate,'and I also place transverse arms 25 integral with the plate 18 and furnish these arms 25 in turn with the lips 26, in this way providing a wider closure and one adapted to prevent the slipping or issuing of-anything from'the mailingtube that might get past a single strip, as shown in Figs. 1 and 3. In this construction I employ the usual sliding strips 21, which have the end lips 23 and the tongues 22, as described before.

In Fig. 5 is shown a still further modified form in which I employ a circular disk 27, which may be provided with the peripheral flanges 28, extending part Way around this disk, being formed with the overlapping parts 29 to form a slot or channel 30 for the sliding of the adjustable arms. In this construction a solid closure is provided, or in case of alarge tube an approximately tight fit, and the contents of the tube are insured against any withdrawal While the device is inserted in the end of the tube.

These modifications are employed and secured into and withdrawn from the tube in the same manner as the construction shown in Fig. 1. In these constructions I have provided an article of the class described that has a range of usefulness not approached by other devices of this class on account of the adjustable feature of my construction,-by which it is adapted to be fitted into tubes of largelyvarying diameters.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1; A closure for mailing-tubes comprising a plurality of members slidable in relation to each other, means for guiding the sliding parts,

and flexible tongues produced on the opposed ends of the members and adapted to be thrust through the sides of the mailing-tubes and folded over upon the tube. 1

2. A closure for mailing-tubes comprising a plurality of members extensible longitudinally in relation to each other, means for guiding the members, lips on the outer ends of the device adapted to abut with the walls of the mailing-tube, and flexible tongues produced on the end portions of the device and arranged to extend through the walls of the mailing-tube and be bent over upon the same.

3. A mailing-tube closure comprising a body portion, transverse arms on the body portion, said bqdy portion being bent to form a channel, members arranged to slide in the channel in the body portion, and means for securing the ends of the members to a mailing-tube.

4. A mailing-tube closure comprising a circular body portion, said body portion being bent to form a diametrically-arranged channel, members arranged to slide in said channel, and means for securing the sliding mem bers to the walls of a mailing-tube.
