PROVISIONAL SPECIFICATION.
Improvements in Button Attachments.
1 JAMES HENRY LYNDE of 17 Cooper Street, Manchester in the County of
Lancaster, Civil Engineer, which invention has been communicated to me from abroad
by Francis Gascoigne Lynde of Ahmedabad, India, Civil Engineer, do hereby declare
the nature of this Invention to be as follows:-
--
This invention relates to improvements in button attachments and consists mainly in
dispensing with the usual shank and split pin attachment and instead combining with
the button a fang or claw device by which the button may be readily attached to or
detached from a garment as required.
In carrying the improvements into effect a hollow metal button is constructed in the
ordinary way but instead of the usual shank, two fangs or claws are substituted.
These fangs or claws are preferably bent at right angles and one is fixed in the body
of the button while the other is movable or both fangs may be movable so that they
can be brought together and inserted into the eyelet or hole in the garment and when
inserted can be moved apart so as to retain the button in position.
For greater safety a combination of a cam plate and spring may be used so that it
is impossible to move the fangs from the extended position unless one of them is first
partially pushed into the button so as to release a catch in the cam plate.
The several thicknesses of cloth when the garment is buttoned will prevent the
movable fang being pushed into the button accidently. The garment being unfastened
sufficient movement will be allowed for the movable fang to be partially pushed into
the button and so disengage the cam plate from its catch. It can then be turned
towards the other fang and be withdrawn from the eyelet hole.

COMPLETE SPECIFICATION.
Improvements in Button Attachments.
I, JAMES HENRY LYNDE, of 17 Couper Street, Manchester, in the County of
Lancaster, Civil Engineer, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Francis Gascoigne Lynde, of Ahmedabad,
India, Civil Engineer, 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 improvements in button attachments and consists mainly
in dispensing with the usual shank and split pin attachment and instead combining
with the button a fang or claw device by which the button may be readily attached to
or detached from a garment as required.
In carrying the improvements into effect a hollow metal button is constructed in
the ordinary way but instead of the usual shank two fangs or claws are substituted.
These fangs or claws are preferably bent at right angles and one is fixed in the body
of the button while the other is movable or both fangs may be movable so that they
can be brought together and inserted into the eyelet or hole in the garment and when
inserted can be moved apart so as to retain the button in position.
For greater safety a combination of a cam plate and spring may be used so that it
is impossible to move the fangs from the extended position unless one of them is first
partially pushed into the button so as to release a catch in the cam plate.
And in order that this invention may be fully understood and readily carried into
LD

page_text: effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figures 1 and 2 are two views of the under side of a button provided with the
improved attachment and showing the fangs or claws in two positions.
Figures 3 and 4 are two sectional elevations of the button."
In these views which for the sake of clearness are drawn upon an enlarged scale, a
designates the movable fang or claw and 6 the fixed fang which is soldered to the
body of the button c. The movable fang a is soldered to a catch or cam plate d with
a bent and recessed end e which fits over the shank of the fixed fang 6 and is thus
retained in position, the cam plate d being pressed down by means of the spring f.
When it is desired to insert or remove a button made as described the movable
fang a is pressed inward thus compressing the spring f and releasing the jaws e of the
cam plate & thereby allowing the movable fang a with the cam plate attachment to be
turned round into the closed position illustrated by Fig. 1. The fangs can then be
inserted into the garment and when this has been done the movable fang a is turned
back to the extended position, Figs. 2 and 3, and retained there by the jaws of the
cam plate d embracing the internal portion of the fixed fang band being pressed
down by the spring f.
The several thicknesses of cloth when the garment is buttoned will prevent the
movable fang a being pushed into the button accidently. The garment being
unfastened sufficient movement will be allowed for the movable fang a to be partially
pushed into the button and so disengage the cam plate d from its catch. It can then be
turned towards the other fang bas described and be withdrawn from the eyelet hole.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The arrangement use and application of fangs or claws forming the improved
button attachment substantially as and for the purposes herein set forth.
2. The combination with the fangs or claws, forming the button attachment, of the
cam plate and spring for locking and retaining said fangs in an extended position as
described with reference to the Drawings annexed.
