IMPROVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 53,9S6, dated April 17, 1866.

To all whom 'it may concern:

Be it known that I, JOHN M. J oHNsoN, of Mamaroneck, in the county of festchester and State of N ewYork, haveinvented anew and use` ful Improvement in Button-Fastenings; and I do hereby declare that the following is a full, clear, and exact description thereof, which will others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in which- Figure 1 represents a longitudinal central sect-ion of this invention, the line a' at', Fig. 3, indicating' the plane ot' section. Fig. 2 is a detached elevation ot the pointed stud which I use to pierce the cloth and fasten the button. Fig. 3 is a horizontal section ot' the same, taken in the plane indica-ted by the line y y, Fig. 1. Fig. et is a longitudinal central section ot' a modification ofthe same.

Similar letters of reference indicate like parts.

This invention consists in the arrangement ot' a pointed stud, with a suitable U-shaped or curved groove, 'in combination with a pin or key projecting' from the inner surface ot' the hollow shank ot' a button, and with a suitable spring secured to the exterior or interior ot' said shank in such a manner that, by means ofthe pointed stud, the material to which the button is to be attached can be readily pierced, and by introducing said stud into the shank and slightly turning it the pill or key is made to catch in the recess of the groove inthe stud4 and thebutton is securelyheld,and by a slight compression otl the spring the stud can be released and the but-ton detached whenever it may be desirable.

A represents a pointed stud, made ot' metal or any other suitable material, and provided with a groove, a, the inner end ot' which is curved or U-shaped, as clearly shown in Fig. 2 of the drawings. Said stud is pointed, so

that by its aid the material to which a button is to be fastened can be readily pierced at the desired spot.

The button B, which is to be fastened by spontaneously.

means of the pointed stud H, is provided with a hollow tubular stem or shank, l), from the inner surface ot' which projects a pin, O,which can be made to catch in the U-shaped groove a of the stud A.

A spring, d, of india-rubber or other suitable material, which is secured to the shank of' the button, has a tendency to keep the stud and the button apart, and if the pin O has entered the inner end ot' the U-shaped groove a it is prevented by said spring from getting out spontaneously.

The spring l may either be secured to the exterior ot' the tubular shank l), as shown in Fig. 1, or to the interior thereof', as shown in Fig. 4, and it may be made of india-rubber or otl metal, in any suitable form or sha-pe.

In order to uni'asten the button the stud must be pressed in against the action ot' the spring d until the pin O leaves the inner end of the groove a, when the stud is slightly turned and withdrawn.

By this arrangement a button can be readily fastened to a garment or other article and unfa-stened therefrom without the aid ot' any other instrument: The stud makes its own hole, and when properly introduced into the button it is not liable to become detached It can be made cheap, it is durable, and its operation is so simple that it can be readily understood by the simplest lnind.

What l claim as new, and desire to secure by Letters Patent, is-

The pointed stud A, with its U -shaped groove, as described, in combination with the pin O projecting from the inner surface ot' the tubular socket b ot' the button B, and with a spring, d, constructed and operating substantially in the manner and for the purpose herein specified.

The above specitication of my invention signed by me 011 this 3d day of January, 1866.

JOHN M. JOHNSON.
