PIN-ON BUTTON.

To all whom it may concern: i

Be it known that I, ANGELO C. RovIiLLI, a citizen of the United States, and a resident of Philadelphia, in the county of Philalike that they can be repeatedly put through a fabric at different places to move the buttons without marring the fabric. The pins are attached to the buttons or button-bodles by clamping devices or provisions of the but-' tons or button-bodies which permit of de? tachment only by turning the studs to unscrew threads on them from disengagement with those devices. The pins or studs must, of course,-have heads which appear on the back of the fabric, which must be large enough not to pull through, and which constitute the sole means for unscrewing the pins. To provide these needle-like pins with appropriate and satisfactory heads at the small cost permissible in the case of such articles presents difficulties. Heretofore the heads consisted of pressed metal disks through which the pins with very small heads were driven, until the head of the pin contacted with the metal disk. The resulting union depends upon a mere tight fit and unless great care is taken, objectionable burs are formed which tend to wear the fabric. Such stud heads are heavy, which in the case of a light fabric is a disadvantage where a row of buttons is employed, for their weight tends to pull the garment and produce an unsightly effect. Without the exercise of great care in manufacture, the heads or disks are apt to be or become loose and turnable on the pins and in that case the pins cannot be unscrewed from the buttons or button-bodies and the buttons become immovable on the fabric and one of the prin- .cipal advantages of the pin-on buttons is Specification of Letters Patent, Patented Apr. 19, 1921.-

ance and finish of the inside of the garment. Sometimes when the stud and button-body have been separated to remove them from the garment, for example to press or wash "it, the stud, being small and comparatively lIlOOIlSplCIlOllS, is lost or mislaid, and as heretofore constructed and under such circumstances the buttonbody was useless, and much annoyance and discomfort resulted.

The principal objects of the present inventlon are, first, to avoid the defects and disadvantages to which reference has been made; second, to provide a stud for pin-on buttons which shall be light and comparatively inexpensive to make and of which the head shall be sightly and thin and well adapted to afford a good finger grip when detaching or unscrewing the parts of the button; third, to insure proper unscrewing act10n between the parts of the button when 1t is to be taken apart; fourth, to avoid the necessity for care in preventing obiectlonable burs and loose joints, such as are apt to be formed orleft where pressed metal caps or disks and pins are united without solder, the cost of which is'prohibitory; fifth, to provide a comparatively inexpensive button-body well adapted for cooperation with its stud and constructed in such a way that it can be sewed on in case the stud is lost or mislaid, and sixth, to provide a comparatively inexpensive, durable and attractive pin-on button possessed of the advantages herein set forth.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it chosen for illustration in the accompanying drawings forming part hereof, and in which- Figure 1, is a view of the under side of the button-body.

Fig. 2, is a section on the line 22 of Fig. 1.

Fig. 3, is a section on the line 3-3 of Fig. 1, showing the stud, and

Fig. 4, is a perspective view of the stud.

The stud consists of a continuous wire of appropriate gage for providing the threaded cylindrical shank 1 having a pointed end 2 of reduced diameter. 3, is a coil of the same wire and it constitutes a fiat head disposed at right angles to the shank and connected with it by a radial portion 4. The head consists of the coil 3 and part 4, is

generally flat for these parts lie in the same plane, and this head is light in weight and attractive .in appearance, since it consists of wire of fine gage disposed in a generally ring-like form or coil which in no way resembles a button and hence does not detract from the interior appearance or finish of the garment. The ring or coil-like shape of the head along with the radial portion 4: afiords a good finger hold for unscrewing the shank from the button-body or button proper. Since the shank-and head consist of a continuous piece of wire they are rigidly connected and there is no possible chance forin close contact with the fabric and no part 7 of the stud tends to unduly enlarge the opening in the fabric through which it is arranged. The button-body consists of a shell 5 and a clamping device 6. The clamping. device comprises a disk perforated to provide oppositely inclined inward fingers7, each notched at its end, as at 8, to

receive the end of the stud, and these fingers permit of the insertion of the stud, automatically grip its shank against withdrawal, and permit the stud to be screwed'o-ut of their grasp. The shell is provided with a projectinghollowshank 9, havinga central hole formed in its countersunk-portion and adapted for the passage of the stud. The clamping disk is arranged in the shank and is'held'in place by its inner wall and by tongues 10, punched out of the wall of the shank, leaving openings ,11, through'wh'ich thread may be passed in order to sew on the button. a In use the described parts cooperate as ,a pin-on button having the desirable features hereinreferred to. The button may beputon by passing the stud throughthe goods the button may be taken off by unscrewing the stud and body, or if'the stud be lost or mislaid the button-body can be sewed'on.

What I claim is: I 1. A stud for pin-onbuttons consisting of acontinuous wire and comprising a threaded cylindricalshank having a pointed end, and a circular coil constituting a flat head and disposed at rightangles to and concentric with the shank, substantially as and for the purposes described. V

v 2. A pin-0n button comprisingthecoinbination of a stud consisting of a continuous wire and comprising a threadedshank having a pointed end and a coil, and a buttonbody consisting of a tongued clampingdisk and a shell havingla neck in which the disk j is arranged and. which is provided with punched disk clamping tongues, and with -and inserting it intothe button-body, and.

thread openings formed where the tongues are punched, substantially as described.
