SPECIFICATION forming part of Letters Patent No. 452,572, dated May 19, 1891.

Application filed November 10, 1890. Serial No. 370,963. (No model.)

T all Z whom it may concern: central opening through it into the shank. Be it known that I, THEOPHILUS R. HYDE, As here represented, the attachment between J r., of Waterbury, in the county of New Haven the back and the shank is made by constructand State of Connecticut,have invented a new ing the shank with an internal flange 1) at its 5 Improvement in Buttons; and I do hereby deother end somewhat larger in diameter than 5 5 clare the following, when taken in connection the diameter of the hole through the back w1th the accompanying drawings and theletand the metal around the hole of .the back ters of reference marked thereon, to be afull, turned into that end of the shank and closed clear, and exact descriptionof the same, and upon the flange b, as seen in Fig. 2, and so as To which said drawings constitute part of this to firmly unite the back and shank; but this speclfication, and represent, in is a common construction for uniting the Figure], aside view of the button complete, back and shank, and for which other known enlarged; Fig. 2,a vertical section of the same; means of connection or construction may be F g. 3, a vertical central section showing the employed. 15 button as applied; Fig. 4, a central section of The flanged or flaring end of the shank gives the collet for upsetting the end of the fast a broad bearing for the button upon the surener; Fig. 5, a modification. face of the material to which it is to be ap- This invention relates to an improvement plied, and the shank is of alength correspondin that class of buttons which are provided ing to the space required between the button 20 with ashank projecting from the back and so and the surface to which the button is to be as to form a firm bearing on the surface of the applied. material to which the button is to be attached The fastening device consists of a tube C andleave a space between the back of the butof an external diameter corresponding to the ton and the said material, the object of the diameter of the hole through the back, but of 25 the invention being to provide such a button considerably less diameter than the diameter with a fastening device within the said shank of the flange orbase of the shank. This tubuas a permanent part of the button itself, but lar fastener is constructed with a flange dprojecting through the shank, so that while around one end, and so that it may be set the shank takes its firm bearing upon the surthrough the back from the front, and so as to 0 face around the hole through which the said bring the flange d to a bearing upon the infasteningpasses the fastening device willproside of the back.

The shank Bis permanently known manner between the back and thefront, and rigidly attached to the back of the butso as to avoid the necessity of the depression 50 ton or made a part thereof, the back having a in the face, it only being necessary that there [00 15 produced by means of a collet F.

5 through the material E corresponding to the tubular fastener C, and so that, the button being placed upon one side, as seen in Fig. 3, the fastener will extend through this opening in the material, and the flange of the shank E will come to abearing upon the material surrounding the hole. Upon the reverse-side the fastener is upset, so as to clamp the material between the flange of the shank and such upsetting of the fastener. This upsettingis best This collet is constructed as seen in Fig. 4-, and consists of a cap G, of sheet metal, and a back it, also of sheet metal, the two closed together at their edges after the usual manner of closing the The back II is constructed with acentral hole I, corresponding to the end of the tubular fastener .l, and the cap G is constructed with a central depression J toward the said hole I in the back This depression J forms a conical projection toward the hole, the center of which is substantially the center of the hole I, and so as to form a deflecting-surface between the front and back This collet is preferably of a diameter substantially corresponding to that of the diameter of the flange a of the shank l; of the button. 7

In applying the button it is set upon the 5 material, as before described, with the fastening-tube O projecting through the hole in the material. Then the collet is set upon the projecting end of the fastener C, so as to bring the end of the fastener into the hole I of the collet, the conical projection J standing within the end of the tube. Then pressure is applied to force the collet onto the tube, in doing which the end of the tube is expanded by the conical projection of the collet and the 5 end of the tube forced between the back and front of the collet. The collet as thus constructed is composed of two pieces only, is very simple in its construction, and securely holds the button. The material to which the button is applied is thus clamped firmly between the flange of the shank and the collet on the back, and so that a bearing is had to such an extent around the hole through the material that the strain of thebutton is taken outside the hole, and so that there is little or no liability of the fastener so working upon the hole as to make it possible to accidentally detach the button.

Instead of a collet such as I have described, a collet I" may be applied, as seen in Fig. 5, having a hole through it corresponding to the end of the tubular fastener and upon which that end will be upset, as clearly seen in Fig. 5, and substantially the same resultaccomplished.

In some cases the tubular fastener may be upset directly upon the material without the interposition of acollet, and substantially the same as an eyelet is upset, the material being so firm as to make such an upsetting practicable; but a collet of some character is desirable.

By this construction of button a broad bearing-surface is provided, and the button contains within itself means for fastening, while the flange around the shank, surrounding, as it does, the hole through which the fastener passes, serves to support the material to which the button is applied and give it a firmness to prevent the easy withdrawalof the fast- C1161.

I claim- A button composed of the metal back A, united to one end of a tubular shank I the other end of said shank. expanded to form an annular projecting flange a, the back constructed with a central opening into said shank, combined with a tubular fastener 0, extending through the opening in the back and through the said shank, the fastener perin anently secured to the button and of a length to project beyond the flanged end of the shank, substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
