io claims'.

My inventionrelates to new and useful im; provements in vises that are to be incorporated in tack, buttons. l

As is well known to those skilled in the art, tack buttons may be made from a molded composition in which thereis located a vise, or vise and anvil, vso that when the tack is driven up into the button for attaching purposes, the vise will guide the tack within the button and deform the prong to thus securely attach the button to its cloth.

Or, in the same manner, when the tack button is formed with a thin metal shell and cap, there is provided a vise and anvil tolikewise deform the prong of the tack and hold the button head in pla-c e. In both instances, the vise or the vise and anvil also prevent the prong of the tack from piercing or deforming the face of `the button.

One of the principal objects, therefore, of the present invention is to provide a vise about which may be molded the composition or plastic button, the vise being so constructed that it will not only assist in guiding the tack prong within the vise but will provide an ample sizechamber for the deformed end of thetack and prevent the point from piercing the face of the molded button, Again, if the vise is used with a metal shell tack button, the vise will .prevent the tack from piercing and disfiguring the embossed cap and securely 'hold the deformed tack prong to thus attach the button to its cloth.

Still another object of the invention is to provide a vise that may be quickly and cheaply manufactured and quickly assembled in a button structure.

Still another object of the invention is to provide a vise that is preferably made in two parts,`

that is, the body portion and acap, the ca-p being rimmed over the body portion to complete the structure. l

Still another object of the invention is to provide a vise that has its upper portion depressed to form a chamber to receive the deformed end of a tack prong and wherein `the.y `substantially integral lcap may be eliminated and aseparate anvil or blank positioned over the vis e,if sodesired. Still, inother instances'it may be possible to just utilize the vise and do away with both the cap and the anvil.k i

Still another object of the inventionfis toI provide a vise wherein the cap, when the cap `form is used, in reality performs a `double. function, that is, it functions as the top wall ofthe cham- (ol. 24-94.)y

ber to Complete, .the 'samefandalso acts 'as an therefrom, unless destroyed, as'the greater the upward force of the tack the tighter the rim Aoi the cap will pull about the rim of the body porf.,

tion.

Still another object'of the invention is to provide `a new and novel form of v.vise `that will guide, receive, and deform the end of the tack during the attaching operation and, at the same time, provide an ample chamber for the deformed tack prong,v so that there is no likelihool or `chance of the crackingofthe plastic button during the attaching operation.

With these and other objects in View, the invention consists in certain new and novel features and combination of parts, as will be hereinafter more fully explained and pointed out inthe claims. n I

Referring v`nowto the drawing showing a preferred and a modied form,

" Fig-8 is a bottom plan view of the button; Fig. 9 is a Viewv similar to Fig. 7, but showing thebutton attached toits material; vand Fig. 10 shows a slightly modiedfform, that is,

the visev used in conjunction 'with a separate anvilpy.. l

At the outset, it might be mentioned that I have only illustratedthe present visev as..being are relatively small, generally less than onequarter inch in height and slightly over onequarter inch in diameter across the cap, but for purposes of clearness. of illustration, I have shown the vise and the button on a greatly enlarged scale.

Referring now to the several views,-I have shown in Fig. 1 the partly formed vise I, which has 'been pressed from a; small. rectangular piece of copper stock (not shown), copper being preferably used due to its ductility and to the furtherfact that it is rust-proof and will not be affected when used in a composition button.

y In Fig. l, I have shown the further step in the formation of the vise, the top surface having been partly depressed and the flaring rim being yannularly depressing the wall in this manner,

it permits the plastic of the button head to flow about the depressed portion and thus more tightly bind the vise against movement within th button head.

The top portion of the metal vise is bent downwardly and inwardly on itself, as may be seen at 8, to form the side walls of the chamber 9 for the reception of the deformed tack prong, as will beshortly mentioned.

The metal that is pushed downwardly, as at v8, terminates at Ill just slightly above the upper edge of the metal, forming the restricted throat 5 heretofore mentioned.

In the formation of the vise, after the metal is forced downwardly at I8, itis pierced, so that the opening I I is in direct registry with the opening of the restricted throat 5.

Now t0 form the dome of the chamber 9, in the preferred form, there is provided the cap I2, as may be seen in Fig` 4, whichI is loosely fitted over the ared rim 'I of the Viseand then rimmed or rolled, so that the downwardly extending iiange I3 of the cap will snugly t about the outer periphery of the flared portion l, as may be clearly seen in Figs. 7 and9.

When this cap is fitted in place, it will be seen that the chamber 9 is completed and will accom'- modate the deformed end I 4 of the prong I5 of the tack I6.

The cap can be of metal of any desired weight .or thickness, so that when the tack Ill in the attaching operation is driven up into the vise, it will be turned and deformed, as may be seen in Fig. 9, without any possibility of going through the cap.

In Figs. 7 and 9, I have shown the vise molded within the plastic button I'I. Thisbutton has the integral hub I8, the flared head portion I9, while a relatively large entrance 20 may be seen, so that if the tack tends to bend in its attaching operation, it will notv Contact with the side walls, which might tend to crack or break the button.

.In Fig. 9, I have shown the tack with its prong I5 having pierced the cloth ZI and deformed within the chamber 9, thus holding the button tightly in its final position.

within said chamber.;

prong may be easily accommodated within the chamber 9.

The tack willbe guided while entering the vise through the restricted throat 5 and also will be guided by the lower end of the Walls 8 that form v the chamber`9, so that there is little likelihood of the tack being driven anywhere except into its receiving chamber 9.

In the modied form as shown in Fig. 10, it will be seen that the vise proper V is in every respect similar to the vise shown in the preferred form, with the exception that in this instance, the usual cap is eliminated. However, in the button Il' just above the vise V, there is provided the separate blank or `anvil 23 to complete the chamber, so that when a tack is driven up into `the vise, its prong will impinge against the said anvil 23, as will be readily understood, and be deformed within the chamber of the vise.

This vise without the integral cap is also readily adaptable for metal shell buttons, as the vise rests within the hub while the anvil placed directly over the vise will be held in place by the button cap (not shown).

From the foregoing, it will be seen that I have provided a vise preferably formed of two parts, which, when assembled, constitute substantially an integral structure.

Due to the internal structure of the vise, the tack, during the attaching operation, will be properly guided up into its chamber, where it will strike against the cap and be readily deformed. Also, due to the size of the chamber and its somewhat resilient sidewall, the deformed prong will be readily accommodated while the internal walls `of the chamber may give slightly without transferring the strain to the outer walls of the vise and consequently to the button.

Finally, in the preferred form, by constructing the vise as shown, an economy may be effected in that the body may be of lighter gauge material than the cap. It will also be understood that it may be possible to use the vise without either a cap or an anvil if the vise were to be used in, say, a solid metal button wherein the top wall of the button would be capable of turning the tack and deforming it within the vise chamber.

Having thus described my invention, what I .claim as new and desire to secure by Letters Patpressed, the upper end of the vise extending back within 4itselfto form the side walls of a slightly .resilient flaring chamber, the bottom of the vise being perfora'te and extending upwardly and inwardly -to form a slightly restricted throat for the. guidance of the prong of the tack fastener,
