LOOP AND BUTTON CLASP.

L236,12 Specification of Letters Eatent.

Application filed August 18, 1914. Serial No. 857,354.

To all whomy t may concern: f

De it known that I, HENRY J. STUART, a citizen of the United States, residing at Derby, in the county of New I-Iaven and State of Connecticut, have invented a certain new and useful Improvement in Loop and Button Clasps, of which the following is a specification.

VMy invention relates to button clasps for garment supporters and like articles, but more particularly to that class of the same in which the button is provided with an elastic collet.

The object of my invention is to provide a button having an elastic collet and a tapecovered base plate which can be economically and quickly assembled.

I vattain this and other objects of my invention in the device set forth in the following description and accompanying drawings in which like reference characters refer to corresponding parts.

In the drawings:

Figure l is a front view of the lower extremity of a hose supporter;

Fig. 2, a central longitudinal sectional view thereof;

Fig. 3, detail views of the rubber collet forming the head and shank of the button;

Fig. 4, a top plan view of the button base and stud;

Fig. 5, a front view of a fragmentary portion of the apertured tab;

Fig. 6, a side view of the base and stud showing the tab secured to the stud, and

Fig. 7, a side view of the button after its arts have been assembled.

The button clasp, which is shown depending from a fold in the extremity of the supporting strap A, consists of an attaching link B, a button loop C, and a button take or tab D which carries a button E at itsV lower extremity. The button loop C, which is connected to the lower side of the link B by a lip F projecting from the upper side thereof, is provided with a bridge Gr and has the sides of its lower extremity contracted to engage the shank of the button E. Vith the exception of the button E the device thus far described is one of the common forms of loop and button clasps well known in the art. Referring to Figs. 1 to 7 inclusive, in Vwhich. the parts are shown enlarged the button E consists of ametal base D. Projecting outwardly and riveted to the base 2 is a wire stud 3. The stud 3 is headed to form a convex cap 4, which is preferably annularly recessed on its under side, to form a peripheral biting edge 5. The elastic rubber collet 6 is shaped to form a head 7 and a shank 8. The collet 6 is provided with a central aperture 9 having an inside cylindrical wall 10 flared outwardly at its upper extremity. The diameter of the wall 10 is less than that of the head 4 and preferably less than that of the stud 3. One extremity of the tab D is punched, before it is applied to the button, to form an aperture 11.

. To assemble the button, the stud 3 is first riveted to the base 2. 'Ihen the apertured extremity of the tab D is slipped over the head 4 of the stud, or to be more exact the head 4 is slipped through the aperture 11 in the extremity of the tab, thereby securing the tab to the stud so that its upper end 12 will slightly overlap one end of the base 2, as shown in Fig. 6. The rubber collet is then sprung over the stud by rst placing the under side of its shank 13 against the head 4 then pressing down causing the head to distort the rubber in the wall 10 of the aperture as the collet passes down on the stud. The pressure of the collet is continued until the under side of its shank 13 presses the edges of the aperture 11 in the tab hard against the front face of the base 2. The vertical dimension of the collet and stud are preferably so arranged relatively to each other that, when the downward pressure on the collet is relieved, the latter springs upwardly engaging the underside of the head 4, and causes the peripheral edge 5 of the latter to become embedded in or bite into the flaring extremity of the wall 10 of the aperture. In this manner the collet is held between the under side of the head of the stud and the top of the base, or to be more exact the front of the tape-covered base, and coacts with the base to prevent displacement of the tab. The tab is then carried around in back of the base 2 and upwardly through the link B, then downwardly and rearwardly through the loop passing over the top of the bridge G. The overlapping ends 12 and 14 of the tab are then sewed together by stitches l5 immediately adjacent t0 the upper end of the base 2,5th`e'e`nd 112 being folded in to form a. hem which prevents fraying. The button base, being confined between the layers of the 'tab 4which are Wider than'the base, is entirely Covered and concealed, thereby obviating any disadvantages incident to the exposure 'of a metal part. It should be noticed that the eXpansive force 'exerted Iby the rubber forming the collet effects a grip Abetween the parts Which prevents them from becoming loose from Wear andi strain and also prevents them from being twisted out of longitudinal alinement. For this reason it is not `necessary to close the layers of the tape along the side edges of the base. In the above description I have referred to thecollet as being made of spring or elastic rubber, yet I may employ a 'collet made out of any other mate rial having characteristics which will enable it to besprung on to a headed stud. Ipre fer, however, to employ `a collet made of spring' rubber since it is the best material, so far as I am aware, to hold the parts together and'to grip the garment.

While the. preferred forms lof my invention are embodied in the devices above'described yet the same are susceptible to such modifications as may fairly come Within the scope of the appended claims.

Having now described my invention What I desire to claimandprotect'by Letters Patent is:

l. In a ybutton clasp a button comprising a baseon vwhich is'mo'u'nted a headed stud, the said base having its front Vsiderfcovered with4 tape which surrounds *the stud and a spring rubber collet surrounding said stud 'in front of the tape and containing a passage therethrough of less diameter than'the head of the stud, the said collet being held against the tape by the under side of the head of the stud, and the saidstud passing entirelythreugh said collet. f

2. In a button clasp a 4button 'having a base on which is mounted a headed stud7 the said base having its frontside-covered With fabric material through which saidstud e tends and an elastic collet slipped over the stud in front of the fabric material and containing a'passa'ge therethroughI of less diameter thanthe head of the-stud, the said stud passing 'entirely thro'ugh `the collet `Which latter entirely fills the space `between the front side of the fabric material and thc under side of the headfofthe stud.

In Witness whereof I have hereunto s'et myhand on this-23rd day of July, 1914.
