GEORGE G. SNYDER, OF NEW YORK, N. Y.

FASTENING nEvioE.

Specification of Letters Patent.

Application filed October 4,

Patented Nov. 14., 1916. 1913, Serial No. 793,492. Renewed April 6, 1916. Serial No. 89,474.

To all whom it may concern Be it known a citizen of the the city of New York, county of is a tubular stem 2, the upper portion of which is providedwith an interior annular enlargement or offset to form a shoulder 3.

Surrounding the hollow stem 2 and closely that I, GEORGE C. SNYoER, United States, residing in New York,

and State of New York, have invented cerembracing the exterior portion of the entain new and useful Improvements in Faslargelnent is a cylindrical thimble 5 having tening Devices; and I do hereby declare the its base terminating in a narrow outwardly following to be a full, clear, and eXact deturned horizontal flange 6, the thimble and scription of theinvention, such as will enthe stem being so proportioned that the up able others skilled in the art to which it per portion of the thimble tightly engages appertains to make and use the same. the outside of the upper portion of the stem, The invention relates to fastening devices, while the lower portion of the thimble is especially of the button-type, and has for spaced laterally from the stem, thereby leavits object to provide a simple and efficient in an annular space 10 between the stem form of fastening which may be convenand the thimble, as clearly illustrated in iently made of two pieces of spun, stamped Figs. 1 and 3. The lower end of the hollow or pressed metal, which, when assembled, stem 2 extends beyond the flange 6 on the will constitute an open centered button or thimble 5, as shown in Fig. 1. the like comprising a main body portion A button of the type described is made including a head and a tubular stem formed by stamping the head 1 and hollow stem 2 of a single piece of metal, and a thimble from sheet metal or other suitable material telescoping with the stem and cohperating and then applying a thimble ofthe form therewith to form a shank inclosing an anshown in Fig. 2 to the stem. By providing nular clamping space between the stem and a close fit between the upper portion of the thimble for the fabric to which the device thimble and the enlarged portion of the is secured. In the preferred forms of the stem, thetwo parts, when assemble by invention the outer. shell of the shank, pressing the thimble over the stem, will not which may be either the stem, or the thimbecome disassociated and the complete butble, is provided with an out-turned flange, ton is sold with the parts so assemble and the inner shell of the shank is projected When applying the device to fabrics, the beyond the edge of the outer shell. to admit fabric material is perforated at the point of the lower edge of the inner s ell being where the button is to be attached without, turned outwardly to form a flange cooperathowever, cutting out any portion of the ing with the flange on the outer member and material,'. and the portion of the material assist in clamping the device to the fabric. surrounding the punched opening is forced In the accompanying drawings, Figure 1 into the annular space 10 between the is a vertical section through a button inhollow stem 2 and the thimble 5 by any volving the invention; Fig. 2 is a vertical suitable means, such as a tubular mandrel section through the thimble member of the or the like after which the projected lower fastening device; Fig. is a vertical secend of the stem 2 is turned outwardly to tion through a button applied to a fabric; form a flange 4, see Fig. 3, substantially Fig. 4 is a vertical section through a modiarallel with the flange 6 on the lower edge fied form of button applied to a fabric; and of the thimble. These various operations Fig. 5 is a similar view 0 a further modiof punching the fabric, stretching the fication. punched fabric over the hollow stem 2 and Referring to Figs. 1, 2 and 3 of the drawforcing the portion of the material suri'ngs, 1 indicates the head portion of a butrounding the punched opening therein into ton, which may be formed of any suitable the annular space 10, and finally turning material, preferably non-corrodible metal, theflange l on the lower end ofthe stem 2, having an open ce ter surrounding which may be conveniently effected by the machine applied securely the fab minimum, even if the fabric is of the finest and sheerest character. The gripping action between the cooperating parts of the button and the fabric is clearly exemplified in Fig. 3, in which the fabric is shown as securely embraced between the cooperating flanges 4 and 6.

In the modification shown in Fig. 4, the button head 1 is provided with an integral tubular stem 2, the upper portion of which is enlarged to provide an interior shoulder The lower edge of the stem 2 is provided with an out-turned flange 4:. In this form, the thimble is located within and coaxial of the stem 2', in which respect the button difiers structurally but not operatively from that shown in the preceding thimble is located coexteriorly of the stem. In Fig. 4, the hollow thimble 5 is of less diameter than the lower portion of the stem 2 to provide an annular space 10 between the thimble and the stem, and the upper part of the thimble is enlarged to form an annular shoulder 5 which fits snugly into the corresponding shoulder 3' formed in the upper portion of the stem 2. As manufactured and sold to the trade, the thimble 5 projects beyond the flange 4 on the stem and is adapted to be turned up by the means described in connection with the form of button shown in Figs. 1 and 3 to form a flange 6 when the button is applied to the fabric. It will be noted that the gripping action between the parts of the button and fabric is similar in all respects to that shown in the and the button is applied therein shown.

11 certain types of fabrics, the binding or and the poses, and in such cases, the flanges, suchas be omitted. Such a form of is illustrated in Fig. 5 which is simiwith the exception that the lar in all respects to that shown in Fig flange 4 on the stem 2 is omitted, and the thimble 5 does not project or extend beyond the lower edge of the stem. In applying this type of but ton, the material is perforated and the edges thereof pace 10, after which the lower edge of the thimble 5 is expanded sufliciently to grip and compress the material against the adjacent wall of the stem.

While the invention has been illustrated and described as applied to buttons, it is obvious that it is likewise applicable to other types of fastening devices, and in this re spect, the button is to be regarded merely as exemplary.

What I claim is 1. A fastening device comprising inner and outer telescopic tubular memb an annular clamping space for the fabric to which the device is secured.

2. A fastening device comprisinginner and outer telescopic tubular members having central openings therethrough, one of said members having a portion of reduced 3. A fastening device involving inner and outer members, one of said members comprising a button head having an integral tubular stem and the other member comprising a coaxial thimble said stem, one of 4. A button involving inner and outer members, one of the same comprising a head and an integral tubular stem and the other comprising a coaxial'thimble attached to d stem, one of said members having a with the other member an annular fabric clamping space, the end of the thimble extending beyond the stem and adapted to be turned outwardly to form a clamping flange cooperating with the lower edge of the stem.

5. A button involving inner and outer members, one of the same comprising a head and an integral tubular stem having a flange on the lower end thereof and the other comprising a coaxial thimble attached to said stem, one of said members having a portion of reduced diameter extending throughout a part of its length to constitute with the other member an annular fabric clamping space the end of the thimble eX- tending beyond the stem and adapted to be turned outwardly to form a clamping flange cooperating with the flange on the stem.
