REMOVABLE PIN-ON BUTTON.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed February 12, 1916. Serial No. 77,912.

To all whom it may concern Be it known that I, ANGELO C. ROVELLII, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Removable Pin-On Button, of which the following is a specification.

The principal objects of the present invention are, first, to provide a separable button which can be readily and, if necessary, repeatedly applied to a. garment or the like without marring the same, which when ap plied is firm, strong and practically impossible of accidental or unintended separation, and which can be readily detached by the convenient separation of its parts whenever it may be necessary or desirable so to do; and second, to provide a construction, combination and arrangement of parts which is comparatively easily made and assembled and in which appropriate materials can be used.

One embodiment of the invention is chosen from others for illustration in th acompanying drawings in which Figure 1, is a sectional view of a button embodying features of the invention. Fig. 2, is a similar View of a button embodying a modification of the invention. Fig. 3, is a top or plan view of Fig. 1. Fig. 4, is a top or plan view of Fig. 2. Fig. 5, is a top orplan view of a detached. part of the button, and Fig. 6, is a side elevation, partly in section, of another part of the button on an enlarged scale.

In the drawings 1, is a set of opposed inwardly yieldable spring tongues carried by the button 2, and adapted to permanently grip and immovably hold a cylindrical shank 3, against sliding motion in outward direction and to permit of freedom of sliding motion in inward direction. 1, is a pin having a needle or like point 5, adapted to repeatedly penetrate a fabric, as a, without marring it, and having a cylindrical shank of uniform diameter adapted to be permanently and immovably gripped by the tongues 1, and having a thread 6 constituting the sole means by which the pin can be released from the tongues. Two tongues are shown but the number may be increased.

I will now described what I believe to be the best construction for a button having the structure, characteristics and advantages above described.

7, is a plate or disk of spring sheet steel or the like and it is perforated as at 8, to provide the tongues 1, and it is also perforated at 9, to form generally semi-circular concavities in the ends of the tongues. The tongues are formed by what is called 'cracking the piece that is left between the perforations 8. The ends of the tongues therefore have a slight inward permanent set. The button 2, is provided with a seat 10, upon which the disk 7, is seated and also with a concavity 11, having a hole 12, which serves as a guide when the pin is inserted and which may be of larger diameter than the pin since it need not engage the later. The disk 7, is held to its seat and against rotation by means of fingers. As shown in Fig. 2, which illustrates a small button, the fingers 18, originally projected from the top of the button but are bent down as shown and in this instance they are doubled on themselves which increases their strength and rigidity. As shown in Fig. 1, which illustrates a large button, the fingers 13, are struck up from the base 1 1, of the enlarged part of the button and are bent as above described. The dotted line 0, indicates the front part or ornament that is usually applied to buttons and which forms no part of this invention.

In use the pin and button body 2, can be assembled by merely pushing the pin into the body and this is easy because the tongues permit the pin to pass between them freely in this direction. The pin does not mar the fabric even though repeatedly pushed through it. The button body and pin are securely held together by the gripping action of the tongues on the pin when an attempt is made to pull the latter out of the button body. The tongues also oppose relative rotation of the pin and button body sufficiently to prevent their accidental detachment, but these parts can be relatively rotated, when desired, and when this is done the parts are easily separated.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of con struction and arrangement without departing from the spirit of the invention which is not limited in regard to such matters or in any way other than the prior art and the appended claims may require.

What I claim is:
