CUFF-BUTTON.

Speccaton of Letters Patent.

Patented Dec. 3, 1912.

Application led November 21, 1911. Serial No. 661,479.

To all whom it may concern:

Be it known that I, HENRY C. JOHNSON, a citizen of the United States, residing at Astoria, Long Island City and State of New York, have invented certain new and useful Improvements in Cui- Buttons, of which the following is a specification.

This invention relates to cuff buttons.

The object of the invention resides in the provision of a cud button particularly adapted for holding together the ends of cuifs formed of unstarched fabric, said button including in its structure a clamping member adapted to be operated on the stem of the button to clamp the fabric at one end of the cuff between the same and the outer head of the button whereby accidental disengagement of the button from the cuff and possible loss of the button is guarded against.

A further object of the invention resides in so constructing the outer head of the button and the clamping member that when the clamping member has been operated to full clamping relation with respect to the fabric the elasticity of the latter will serve as a means to lock the clamping member against movement from clamping position.

With the above and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a side elevation of a culi' button constructed in accordance with the invention, Fig. 2, a longitudinal section of what is shown in Fig. 1, Fig. 3, a section through the button hole at one end of an iinstarched cuff showing the button applied, certain parts of the button being in section and the clamping member positioned in full clamping relation to the fabric of the cuff, Fig. 4, a view similar to Fig. 3 with certain parts of the button in section and the clamping member positioned to show the compression of the fabric that would arise when the clamping member is moved from full clamping position shown in Fig. 3, the

elasticity of the fabric serving to resist such compression and thereby locking the clamping member against movement from full clamping position, and Fig. 5, a section on the line 5-5 of Fig. 1.

`Referring to the drawings the button is shown as comprising an outer head 10, an inner head 11 and a shank 12 connecting said outer and inner heads. The outer head 10 is of substantially elliptical formation and has its inner face dished as at 13. The shank 12 is threaded as at 14 and movable on this threaded portion of the shank is a clamping member 15 whose long axis is of greater length than the short axis of the outer head but of less length than the long axis of said outer head.

In applying the button the fabric at one end of the cuff is disposed between the outer head 10 and the clamping member 15, while the fabric at the other end of the culi' is disposed between the clamping member 15 and the inner head 11. When the button is thus associated with the cuff it is only necessary in order to secure the button against accidental disengagement from the cuff and possible loss, to operate the clamping member 15 toward the outer head 10. During the `final movement of the clamping member toward the outer head and when the long axis of the clamping member is disposed parallel to the short axis of the outer head the fabric will be compressed between the clampingmember and outer head so as to resist further movement of the clamping' member. This resistance however is manually overcome and the clamping member is moved to the position shown in Fig. 3 when the button will be secured to t-he cuff in a manner that will provide against accidental disengagement thereof. When the clamping member is disposed in the position shown in Fig. 3 movement thereof away from clamping position would result in a compression of the fabric between same and the outer head, but as such compression of the fabric is resisted by the elasticity of the latter, such elasticity will serve to efficiently lock the clamping member against accidental movement fromfull locking position.

What is claimed is:

The combination with a cuff button including a threaded stem and a head having its under face dished, said head having a maximum and a minimum transverse dimension, of a clamping member screwed on to In testimony whereof I ax my sgnat the stem and adjustable thereon into and ture, in the presence of tWo Witnesses. out of the concavty of the head said clamping member being longer than the minor di- HENRY C' JOHNSON' mension and shorter than the major dmen- Witnesses: sion and narrower than the minor dimension FRANCIS BoYLE, of the head.
