IMPROVEMENTS IN BUTTONS
Year: 1885

page_text: We CHARLES STEPHEN GOODWIN, of the City and State of New York, United
States of America, Secretary of Cemetery Association, and NOYES FINK PALMER
of Jamaica, State of New York, United States of America, Civil Engineer, do
hereby declare the nature of our invention for IMPROVEMENTS IN BUTTONS, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
This invention relates to a button made with a removable cap piece, so that the
appearance of the button may be readily changed.
In the accompanying drawing, fig. 1. is a central section of our improved button.
Fig. 2. is a similar section of the cap piece.
Fig. 3. a similar section of the head.
Fig. 4. a side view of the shank.
Figs. 5, 6, 7, and 8 are corresponding views of a modification.
With particular reference to figures 1-4 the letter a represents the head of a
button, convex on top and provided with a central screw threaded aperture,
extending from face to face. bis the removable cap, being made in the form of a
curved shell, the lower or concave side of which is of less curvature than the
convex side of head a. In this way the head and cap are separated and the
covering of the head will not be injured by the cap.
The cap b has a turned down edge, which embraces the edge of head a. At the
center the cap b is provided with a screw threaded pin c having a conical shoulder d
at the top. The pin c fits into the screw threaded aperture of head a, the shoulder d
preventing the cap from being screwed down too far.
e is the shank of the button made with an upper and lower flange f, f¹, and with
screw threaded pins g, g', projecting outward from such flanges. The lower pin g¹
is embraced by a nut h. In use, the head a is screwed upon pin g, while pin g¹ is
passed through the garment and is embraced by nut h. The cap 6 is screwed upon
head a, as already described.
With particular reference to figures 5-8, the head a is screw threaded around
its circumference, to fit a corresponding internal screw thread on cap b. A small
tongue or spring catch i on head a fitting into a notch on cap b, prevents the parts
from becoming automatically unscrewed. In order to separate the parts a, b, the
tongue i must be first depressed so as to be clear of the notch.

page_text: In place of using the shank e, we employ a twisted spring j, fitting with its two
ends into an enlargement of the central perforation of head a while its looped end
projects beneath said head. By means of this loop the button is attached to the
garment.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
First. The combination of head a, perforated at its center, with cap b, having
pin c, and with the shank e, having pins g, gl, substantially as specified.
Second. The combination of convex perforated head a with curved cap b,
having pin c, the curvature of cap b being less than that of head a, substantially as
specified.
Third. The combination of perforated head a, with cap b, having pin c, and
shoulder d, substantially as specified.
Fourth. The combination of perforated head a, having tongue i, with cap b,
having a notch to receive said tongue, and with the spring ), substantially as
specified.
Dated the 29th day of September 1885.
