L. REITER TACK BUTTON Sept. i7, l935.

Filed April 26, 1954 INVENTOR I [ues Helfer BY 1 Patented Sept. 17, 1935 UNITED STATES PATENT oFFlcE 13 Claims.

This invention relates to tack buttons and particularly, to the type adapted to have the head thereof covered with cloth for use in caps and other articles of wearing apparel.

Such buttons consist of various parts adapted to be assembled by the user and sold separately, usually in sets. Each set may consist of a head designed to be covered with cloth or the like by the user, a cup to hold the head, and means to secure the button to a sheet of material, which means may include a slitted washer and a cooperating tack.

My invention contemplates the provision of simple and adequate means for rmly and permanently connecting the cup portion of the button to the fabric or other material to which the button is secured, which means may be quickly and easily assembled, and once assembled, cannot be separated without destruction of the parts.

My invention'further contemplates the provision of a grooVed tack adapted to cooperate with a slitted washer provided-with a perforated offset portion, part of the washer entering the grooves of the tack in such a manner as to permit the forcible passage of the tack in one direction, but preventing retraction of the tack in the other direction.

My invention further contemplates the provision of a simple method of making the slitted washer.

My invention further contemplates the provision of simple and effective means for securing the button head to the button cup against ac-V cidental separation and against separation under the usual stresses.

The Various objects of my invention will be clear from the description which follows, and from the drawing, in which,

Fig. 1 is a top plan view of my improved button in the assembled positions of the parts, cer- -tain of the parts being broken away to show the underlying structure.

Fig. 2 is a vertical section of the same, showing the parts in assembled position andv secured toa piece of material.

Fig. 3 is a top plan view of the cup portion of the button showing the slitted washer and the means for securing said washer in place in the cup. Fig. 4 is apvertical section of my improved button as it appears prior to the bending of the lrim of the button head intov its secured position.

Fig. 5 is a vertical section of the slitted washer as it appears in the rst operation of making the same.

Fig. 6 is a similar View of the same as it appears after the next operation.

In the practical embodiment of my invention 5 which I have shown by way of example, the button comprises four parts. The parts, as has been hereinbefore indicated, are sold disassembled to the user, who covers one of the parts and then assembles and secures said parts to an article 10 of apparel to form the complete button. One of the parts, the button head It, is made of suitable material, preferably thin non-rusting metal, and is provided with a preferably convex top as i I and a depending bendable cylindrical ange 15 or rim l2, being completely open at its bottom to receive the cup portion I3 of the button.

Said cup portion serves a double function. First, it serves as retaining means for the slitted washer Iii, and second, it serves as a means 2o for r'mly holding the button head i0 in place. The cup is therefore provided with a bottom portion I5 which is provided with a central opening as Iii for the passage of the shank I'I of the securing tack I8. 25

The material I9 surrounding the opening It is preferably bent slightly upwardly in order that the point 2B of the tack and part of the shank I'I may be readily passed through the opening without material resistance, said opening being also made preferably somewhat larger than the diameter of the shank Il for that purpose.

Upstanding from the bottom I5 and integral therewith is the outwardly flared wall portion 2i of the cup. At circumferentially spaced intervals, part of the material of the wall 2| is bent inwardly and downwardly away from the wall and on to the upper surface of the peripheral portion 22 of the washer I4, thereby securely clamping said washer against the bottom l5. Clamping lugs as 23 are thereby provided and openings 24 are thereby formed in the wall 2|.

The central opening 25 in the washer is of less diameter than that of the shank I'I of the 45 tack, whereby the material 2b of the washer surrounding the opening 25, inwardly overhangs the material i9 surrounding the opening I6 in the Vbottom of the button cup. Furthermore, said material 2t of the washer is offset from 50 the peripheral portion 22 of the washer, as will be seen from Figs. 4 and 6. To form the offset portion 26, and at the same time to form the opening 25 and the spaced slits'2'l, the washer Ell is cut from sheet material while the slits 21 55 and the opening 25 are simultaneously cut, the cutting dies being suitably shaped to offset the slitted portion 26 laterally in a manner which will be clear from Fig. 5.

In the above described operation of forming the washer, it will be noted that the slits 2'I are opened or spread, and that the portion 26 is offset a greater distance than is desired in the finished washer. To close the slits 27, the material 26 is then pushed back toward the plane of the periphery 22 into the position shown in Fig. 6 whereby the slits are closed and the desired lateral offset is attained.

The shank I I of the tack is provided with a series of opposed circumferential grooves therein as 28 and 29, each of the grooves being adapted to receive the inner peripheral portion of the material 2S of the washer. To assemble the parts, the point 29 of the tack is pushed through the material 38 to which the button is to be secured and through the opening I6 of the bottom of the cup portion until the point 2i) passes into the washer opening 25. Further pressure exerted upon the tack causes the shank I'I to enlarge the washer opening 25, the slitted portions of the washer being additionally offset at the same time into the position shown in Fig. 2. When the head 3| of the tack and the bottom I5 of the button cup have been brought as closely together as is possible, they cooperate to clamp the material 3i) between them, the portions 25 of the washer at this time slipping into the

grooves

28 and 29.

Since the washer is of substantially the same diameter as the cup bottom I5, it will be evident that the tack I8 cannot be retracted without destruction of the parts, whereby the parts are firmly and permanently secured together and the button secured to the material 3U.

At its upper end, the cup portion I3 is provided with a rim 35 which is slightly flared outwardly and which is of greater diameter than any other part of the cup. Said rim 35, however, is of slightly less diameter than the rim I2 of the button head whereby the cup rim may be easily inserted within the rim of the head with an infolded part 36 of the button cover 31 therebetween, as will be clear from Fig. 4. The height of the rim 35 is comparatively small as compared to the total height of the button and is further of less height than the connecting wall portion 38 which connects said rim 35 with the wall 2| of the cup portion and which is integral with the rim and said wall 2 I.

The lower portion of the connecting wall 38 is preferably' cylindrical in shape while the upper portion 39 is curved outwardly to `ioin the bottom of the rim 35 and to provide a re-entrant concave recess for the reception of the lower portion of the button head rim I2 when said rim is bent to secure the head of the button in place.

As will be seen from Fig. 2, the button head is covered with the cover 31 which is usually of ilexible material matching the material 3U, such as fabric, leather or the like, the cover being infolded about the lower edge of the rim I2. The parts having been assembled into the position shown in Fig. 4, the rim I2 is then bent inwardly toward the re-entrant recess provided by the curved portion 39 of the connecting wall 38 to lock the rim in place, the rim being, if desired, confined in suitable dies to prevent excessive crimping thereof. The extreme peripheral edge 40 of the button head rim I2 is thereby carried inwardly a sufficient distance to prevent separation of the cup portion I3 from the button head I 0. As shown in Fig. 2, which indicates the final or assembled position of the parts, the extreme upper edge of the cup rim 35 is preferably arranged outwardly beyond the extreme lower edge 40 of the button head rim I2 when the button has been completely assembled, whereby the button head cannot be separated from the cup accidentally or under the stresses normally or accidentally put upon the button when in use.

It will be seen that I have provided a simple, 10 inexpensive but efficient structure adequate to permanently secure the button to an article of wearing apparel and practically inseparable therefrom without destruction or distortion of the parts, that I have further provided a but- 15 ton wherein the head is securely attached to the button cup without danger of separation of the parts, and that I have provided a structure which while simple, is well adapted to meet the severe requirements of practical use. 20
