PROVISIONAL SPECIFICATION.
Spring Shank Button.
I, WILLIAM DUNCOMBE DALE of 57 Cecil Road Plaistow, Essex, Aeronaut,
do hereby declare the nature of this invention to be as follows:
My invention consists & is comprised of the attachment of a spring or springs
to the shanks of buttons of any or every description, and the object is to keep the
button, when sewn on the garment always flat and in position by means of the
action of the spring or springs above referred to, so that the buttons will always
look flat and tight onto whatever they are sewn, and so prevent the dropping and
slovenly appearance so often seen in buttons now in general use. The
shank of the button is loose or detached and the spring or springs are in the body
of the button and are attached to the loose shank in such a manner as always to
exert a pressure so as to force the loose shank into the body of the button. I do
not bind myself to any particular shape of button, nor to any particular shape or
kind of spring or springs.

COMPLETE SPECIFICATION.
Spring Shank Button.
I WILLIAM DUNCOMBE DALE of 57, Cecil Road, Plaistow, in the County of
Essex, Aeronaut, 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 :-
My invention for a spring button has for its object to keep the button when
secured to the garment always flat and tight against the material and so prevent
the drooping and slovenly appearance so frequently presented by buttons as
ordinarily constructed and secured, and consists in forming the button with a loose
shank one end of which is secured to the garment in any suitable manner while
the other end engages with a spring or springs enclosed in the body of the button
so as to always press the back against the material.
In the accompanying sheet of illustrative drawings,
Fig. 1 represents in cross-section and to an enlarged scale a button secured to a
garment in an open or unbuttoned condition and
Fig. 2 represents the same in a buttoned condition.
The shank a which works loosely in a slot b in the back c of the button is secured
to the material by the pin d and washer e (but it may be secured by sewing or any
other convenient means) while the other end terminates in a disc f which engages
with the back of the spring g enclosed in the body of the button so as to always
tend to force the said disc towards the crown of the button and consequently the
back of the button against the material to which the shank is attached.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
°
1. A button having a spring or springs engaging with its shank so as to press the
back of the button against the material to which the shank is secured substantially
as described and for the purpose set forth.

page_text: 2. The arrangement and construction of spring buttons substantially as described
with reference to the drawings.
