BUTTON FASTENER Filed June 22, 1936 Patented Oct. 3, 1939 UNITED STATES PATENT OFFICE BUTTON FASTENER Application June 22, 1936, Serial No. 86,554

22 Claims.

Thisinvention relates to button fasteners suitable for all types of garment buttons, especially uniform buttons, and also suitable for emblems.

The principal object of my invention is to provide a metal staple-like fastener which will permit quickly putting a button on a garment or taking it off, Without sewing and without damage to the goods.

I am aware that various forms of wire staples have been proposed for button fasteners, but they have invariably contemplated the use of fairly heavy wire so as to permit notching the wire to receive keeper means, or else have involved the heading of the end of the wire to cooperate with the keeper means. In either event, such fasteners were too heavy and too large and resulted in damage to the fabric. The fastener of my invention involves the use of light wire staples pointed on the ends so as to facilitate passing the same through the fabric` and avoid damage thereto, besides affording the requisite degree of ilexibility, which is taken advantage of in the locking of the staples to their retainers. The retainers, in accordance with my invention, are of small size to be inconspicuous when in place abutting the fabric on the inside and have therein slidable keepers adapted for quick and easy operation with a linger-nail or any convenient small object. The retainers are so designed that although the keepers may be operated easily they nevertheless fasten the buttons securely against accidental removal.

The invention further aims to provide a fastener for buttons, emblems, and the like, the parts of which are susceptible of manufacture in large quantities at low cost, the retainer being designed for production from sheet metal by simple blanking and forming operations, and the keepers and staples used in connection therewith being likewise designed for economical production.

In the accompanying drawing illustrating the invention- Figure 1 is a -perspectve View, approximately actual size, of a typical staple and its cooperating retainer;

Figs. 2, 3, and 4 are sections showing three kinds of buttons all using the same form of retainer but different staples of generally similar form;

Fig. 5 is a cross-section on a larger scale through the retainer, taken on the line 5-5 of Fig. 2;

Fig. 6 is a view similar to Fig, 5, but showing the keeper in a moved position with the staple removed;

Figs. '7 `and 8 are cross-sections on the correspondingly numbered lines of Fig. 5, and

Fig. 9 is a section similar to Fig. 7, showing a modied or alternative construction.

Referring first to Fig. 1, I0 is the staple and Il is the retainer therefor, both made in accordance with the invention. The staple shown happens to be one adapted for insertion through an ordinary two-holed button I2 (Fig. 2) in the fastening of the button to the garment fabric, indicated at I3. The retainer II is designed as hereinafter described to receive the prongs I4 of the staple in the holes I5 and to lock the prongs therein by means of the keeper i6, which, as will presently appear, is slidable back and forth in the retainer to and from locking position. Where it is de-v sired to have the staple rigid with the button, as in Fig. 3, a staple like that shown at Illa is secured to the back wall of the button I2a in any suitable or preferred manner, but is formed so as to provide the same prongs III as on the staple IIl for cooperation with the keeper I6 in the retainer II. Also where a button like the uniform button I2bshown in Fig. 4 has an eyelet II projecting from the back thereof, my invention is applicable by simply forming a loop I8, as indicated on the staple IDU, to receive the eyelet I'I, the staple being otherwise similarly formed as the staple I0 to provide prongs I4 for cooperation with the keeper I6 in the retainer II. Manifestly, an emblem may be equipped with a staple rigid with the back thereof similarly as the button I2a, so that my invention enables the fastening of emblems quickly and easily and, as will soon appear, the prongs of the staple being pointed and of small cross-section, no damage is done to the fabric so that the emblem or button, as the case may be, can be put on and taken off repeatedly Without any perceptible damage to the material. This is particularly advantageous in the case of fancy buttons, which, as is well known, have to be removed from a garment when it is sent to the cleaners. With my invention, such buttons can be removed and replaced readily, and all of the work of cutting off and re-sewing buttons is eliminated, and, besides, no damage is done to the material. It will soon appear that while a twopronged staple is generally preferred, it would be possible to fasten buttons with a single-pronged staple, where, for example, as in the case of an ornamental button, there would be no particular objection to the buttons turning. Ordinarily, however, two-pronged staples are preferred.

The staple I0, as well as the staples Illa and Illb, is formed from a single piece of spring Wire of small cross-section to provide the two substantially parallel prongs I4 pointed on the ends, as indicated at I9, to facilitate passing the prongs through the fabric. The prongs are crimped, as at 20, in a predetermined spaced relation to the pointed extremities I9 to provide offset portions used in the locking of the staple in the retainer II on the abutments 2l provided in said retainer for that purpose. Now, the small cross-section of the wire employed not only facilitates forming the staples in the manner described, but it is of advantage from the standpoint that it reduces the weight of the assembly proportionately, makes for still easier passage of the prongs through the fabric when a button is being fastened, and increases the exibility of the prongs to facilitate locking the same in the retainer. The staples may be made either so that the `prongs I4 as'they Y are entered through the holes I5 have to flex inwardly toward each other slightly in order to pass the abutments 2l, or else the prongs will be arranged to passthe-abutments 2I without flexing inwardly toward veach other as the prongs are ,entered through the holes I5, and then these prongs will be arranged to flex outwardly to engage the offset portions 20 with the abutments 2l, under the action of the keeper I6. The latter is guided in the holes 22 to slide back 4and forth in the retainer I I, and has its intermediate portion enlarged to keystone shape to provide the inclined cam surfaces 23, which, upon movement of the keeper transversely with respect to the staple and between the prongs I4 thereof, are arranged to engage the prongs from the inside vand move the same outwardly to engage the offset portions 20 with the abutments 2I and thus lock the staple against removal from the retainer. At the high points of the surfaces 23, slight depressions are formed, as indicated at 24, to accommodate the prongs I4 and thus lock the keeper releasablyin its operative position, that is, the prongs I4 at the extreme point of their spreading toward the abutments 2I` are permitted to drop back a trifle into these recesses 24, just enough to resist movement of the keeper back toward its retracted position in which it appears in Fig. 6. The keeper, it will be noticed in Figs. 5 and 6, has the two ends thereof reduced for projection throughthe holes 22 and to provide operating ends a and b, one of which projects from the retainer when the keeper is in either of its two extreme positions, so that it is at once apparent to the user which Way the keeper must `be moved to fasten or unfasten a button, as the case may be. Thus, when the button is fastened, as in Fig. 5, the operating end b projects, and one may unfasten the button by simply depressing this end with the finger nail, or any small object suitable for this operation. In the other extreme position, the end a, projects as in Fig. 6, and when this end is depressed after the prongs of a staple have been entered in the retainer, the prongs will be locked as previously described. One can easily tell by the slight click which is'audible when the prongs I4 snap into therecesses 24 at the end of the movement of the keeper I6, so that there is no danger of leaving a button only partially fastened. In passing, attention is called to the transverse groove 25 provided in the retainer I I opposite the holes I5 and in alignment therewith. This'groove receives the pointed ends I9of the prongs, and not only protects the same from damage, but holds the ends of the prongs. against side-wise movement with respect to the retainer, so that the stav and e.

ple is firmly held in right-angle relation to the retainer. This is of advantage from the standpoint that the button is always properly supported and will not sag untidily, and it is moreover of advantage because the staple is held in the proper relation to the keeper so that there is less likelihood of the staple becoming accidentally unlocked.

In Fig. 9, the staple I0 is shown as formed like the staple Ill, but with its offset portions bent outwardly as at 20 instead of inwardly as in Fig. '7. The abutments 2I' on the retainer II for cooperation with these offset portions are correspondingly shaped.` Similar results are obtainable with such a construction, although at present I prefer the one previously described.

In conclusion, it will be seen that I have provided as fastener for buttons, emblems, and the like, of unusually simple and economical construction and one which is moreover extremely light and compact. A saving in cost is realized by reducing the construction to three parts, to Wit: The staple IE, retainer II, and keeper I6. Furthermore, the fact that the stap-le can be formed in a simple Way from spring wire and the keeper I6 can be stamped from sheet metal to the form desired in a single operation, makes for greater economy. Then too, the retainer is made from a single pieceof sheet metal which is first blanked to provide a central portion c, destined for the back Wall of the retainer, and contiguous portions d, and e for the bottom and top walls, and other contiguous portions f and g for the opposite end Walls. Now, the portions d and e are longer tabs than the portions f and g, so that when all of these contiguous portions are bent at right kangles to the central portion c lthey define the four Walls of the retainer, and' the keeper I6 can be assembled in the holes 22 which open from the outer ends of the tabs'f and g, whereupon the portions d and e of the tabs d and e, respectively, can be bent inwardly at right angles thereto to complete the assembly. In the rst forming operation, a rib 26 can be formed in the central portion c to provide on the inside thereof the groove 25, previously described. At the same time, the abutments 2| can be formed in the portions d Then only two additional forming operations are required, one to bend the portions d, 6, f, and g at right angles to the central portion c, and another to bend the portions d and e at right angles to the portions d and e, respectively, as previously described.
