COMPLETE SPECIFICATION.
Improvements in Separable Buttons.
We, WILLARD AI INGALLS, Jeweller, and ALBERT SHERMAN DAVIS, Lawyer, both
residing at South Bend, in the County of Pacific, and State of Washington, United
States of America, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: —
Our invention relates to a novel form of separable button, and more particularly
to that class of jewelry buttons intended for collars, cuffs and the like, and the
object is to provide a simple and efficient button of this class.
To this end the invention consists in the construction, combination and arrange-
ment of the same as will be hereinafter more fully described and particularly pointed
out in the claims.
In the accompanying drawings the same reference characters indicate the same
parts of the invention.
Figure 1 is a perspective view, partly in section, of our improved separable button
with the parts assembled.
Fig. 2 is a similar view, with the back and head separated; and
Fig. 3 is a transverse section through the hollow shank 2.
1 represents the back of the button, and 2 the integral hollow cylindrical shank,
which is formed with an internal flange 3, and 4 represents a longitudinal radial
tooth or rib, fixed to the inner wall of the shank 2, contiguous to the flange 3.
5 represents the button head, and it is provided with a solid stem 6, terminating
in a conical point 7, from which an integral spring pawl 8 extends divergingly
from the stem 6. The free end of the pawl 8 terminates in a tooth 9, which is
adapted to engage the flange 3 in the hollow shank 2, to hold the head in place
in said shank. The conical end 7 of the stem 6 snugly fits a correspondingly
formed recess 10 in the shank 2, which serves to hold the solid stem 6 in place in
said shank.
The rib 4 is preferably V-shaped in cross section, so that the spring tooth 9 may
ride upon either of its inclined sides to carry it out of the path of the flange 3, and
thereby release it from the back portion 1, when it is desired to separate the button.
Although we have specifically described the construction and relative arrange-
ment of the several elements of our invention, we do not desire to be confined to the
same, as such changes or modifications may be made as clearly fall within the
scope of our invention, without departing from the spirit thereof.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim fis: :-
1. A separable button comprising the back having the integral tubular stem
formed at its lower end with a conical seat and at its upper end with an inwardly-
projecting continuous annular flange, and with an internal rib provided with
inclined sides, and a head provided with a stem tangentially slit longitudinally
its length from its upper to its lower end to form a spring arm terminating at its

page_text: upper separated end in a tooth adapted to engage the inwardly-projecting flange,
the conical end of said stem resting in the conical seat of the shank, whereby
lateral or wabbling motion of one part of the button with respect to the other part
ia prevented, substantially as set forth.
2. A separable button comprising the back 1, the integral tubular shank 2,
provided with the conical recess 10, annular flange 3, and tooth or rib 4, in com-
bination with the button head 5, provided with a stem 6, formed with a conical
point 7, and a spring arm 8 terminating in a tooth 9 adapted to engage the flange 3
of the shank 2 to secure said head to the back, substantially as shown and
described.
Dated this 28th day of December 1897.
