CUFF-BUTTON.

SPECIFICATION forming part of Letters Patent No. 626,433, dated June 6, 1899.

' Application illecl March 24,1899. Serial No. 710,324. (No model.)

T0 (tZ/ 'l0/wm, it mfr/y concern: i

Be it known that I, HENRY A. L. LIBAIEE", of New York city, county and State of New York,have invented new and useful Improvementsin Cuff-Buttons, of which the following is a specification.

This invention relates to a separable cuffbutton which is made springless and so formed that the elasticity of the cuff itself will prevent the two sections of the button from becoming accidentally seperated.

In the accompanying drawings, Figure lis a perspective view of a cud provided with my improved button; Fig. 2, atop view thereof; and Fig. 3 a detail perspective View of the two parts of the button, showing them separated.

The letters a a' represent the two heads of the button secured at au inclination to a stem b and a tube c, respectively. The stern b is of a diameter to iit into the tube and carries a laterally-projecting pin b. The tube c is provided with a bayonet-slot c', which merges into a return-pocket c2. At the free end of the tube c there is formed a collar or flange d, which is cut away opposite the slot c', so that the latter is accessible to the pin b. The slot c' extends only along the inner part of the tube c, and the pin b is placed at a distance from the end of the stem h. Thus when the two sections of the button are assembled the tube will telescope the inner end of the stem only, while the outer end of the stern remains exposed, and consequently the collar d will be placed at a distance from each of the heads a a.

In use the stem Z2 and tube c are slipped through the two buttonholes of the cuif A, and the stem is pushed into the tube and rotated, so that the pin b passes through the slot c' Ainto the pocket c2, when the parts will be properly connected. In this closed position one flap A of the cuff will be supported upon the stem b and bear normally against the head a, while the other flap A2 will be supported upon the tube c and bear normally against the head ct'. Thus the natural elasticity of the cuff will tend to force the two parts of the cuff-button outward in opposite directions, so that the pin b is prevented from becoming unseated. Ii", however, either of the flaps A' A2 is subjected to ou tside pressure, as when the wearer bears upon the cu in writing, the flaps would be apt to be pushed off the inner ends of their respective seats b and c and upon the seat of the other flap; but as the button is made springless this displacelnent of the cul would remove the outward pressure against the heads et a and would render the parts b c liable to become separated. This tendency is, however, overcome Vby the separating-flange d, which con nes each cuifsection to its seat and prevents it from passing over the edge thereof and upon the adjoining seat. Moreover, if the sections do become separated the ange CZ will hold the section c a securely suspended from flap A2, while the pin b' Will hold the section b a securely suspended from ap A'.

To open the button, it is only necessary to force the heads inwardly against the resiliency of the cuff and to then turn one of the parts, so as to disengage the pin b' from the slot c c2.

What I claim is- In a springless cuff-button, the combination of stem b having inclined head a, and pin b', set back from the end of the stem, with tube c, having inclined head cd, and a bayonet-slot c', c2, that extends along the inner end of the tube only, and with a collar d, mounted on said inner end and cut away op posite to slot c', substantially as specified.
