BUTTON.
SPECIFICATION forming part of Letters Patent No. 659,905, dated October 16, 1900.
Application filed December 29, 1899. Serial No. 741,936. (No model.)
To rtZZ whom it may concern:
Be it known that 1, JOHN PETER CARL WEIS, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Pearl, Shell, or Similar Buttons, of which the following is a specification.
This invention has reference to an improvement in pearl, shell, horn, and similar buttons; and it consists in the peculiar and novel construction whereby metal shanks are secured to the buttons, as will be more fully set forth hereinafter.
In buttons made of tortoise-shell, pearl, horn, and similar material it is desirable to secure metal shanks without penetrating the face of the button. When the shanks are secured by screw-threading the button-blank, the shanks soon get loose.
The object of this invention is to firmly and durably secure the shank without penetrating the face of the button, and to this end I provide the back of the button with two undercut circular recesses and insert a shank provided with a dovetail end, securing th same by metal washers.
Figure 1 is a view of the back of the button, showing the same provided with two concentric undercut recesses. Fig. 2 is a sectional view of the button. Fig. 3 is a sectional view of the button, showing the shank inserted in the central recess with a metal washer surrounding the dovetail end of the shank. Fig. i is a sectional view of the button, showing the end of the shank secured in the central recess. Fig. 5 is a sectional View of the button, showing the shank extending through a dished metal washer. Fig. 6 is a sectional view of the button, showing the shank firmly secured in the button; and Fig. 7 is a sectional view of a complete button.
In the drawings, a indicates the back of the button; I), the face or front of the button; 0, the shank-wire; d, the dovetail end of the shank; e, the central undercut recess in the back of the button; f, the undercut recess concentric with the central recess 6, and g a metal ring having an internal opening slightlyin excess of the diameter of the shank, so as to pass readily over the shank. In practice I find that a ring of copper answers best, and in carrying out my invention I place the dovetail end d of the shank into the central recess 6 within the ring as is shown clearly in Fig. 3. The button is placed into a suitable holder and the ring g is subjected to pressure by a suitable die or a burnishingtool until the ring is spread out laterally to fill the recess and bear on the dovetail end of the shank, thereby firmly securing the end of the shank.
To give to the shank a firm lateral support, I place the concaved or dished washer 7L around the shank and into the undercutf, as is shown in Fig. 5, and I then force the metal washer it into the recess by a suitable die or by means of a suitable burnishing-tool, so as to completely fill the recess and crowd the metal against the shank. In practice I find the use of a burnishing-tool in a lathe to be sufficient to secure a firm connection of the shank by the spreading out of the ring 9 and the washer lb. The washer h may be of any suitable composition of metal, and while I find copper well adapted for the ring g other metal or composition of metals may be used.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a pearl, shell or similar button, a metal shank having a dovetail end, and a metal ring expanded into the undercut recess and onto the dovetail end of the metal shank; whereby the metal shank is secured to the button, as described.
2. In a pearl, shell or similar button, the combination with the button and the two concentric undercut recesses e andf, of the shankwire 0 having the dovetail end d, the metal ring g compressed to fill the space between the dovetail end of the shank and the undercut margin of the recess c, and the washer h compressed to fill the space in the recess f between the undercut margin and the shank, as described.
3. In a pearl, shell or similar button, two undercut concentric recesses one below the other, and a shank having a dovetail end secured in the recesses by metal forced into the recesses and expanded to secure the shank, as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN P. CARL WEIS.
