Improvements in Buttons.
We, TномAS CARLYLE and JOHN MARK CARLYLE, of Lower Portland
Street, Aston, Birmingham, in the County of Warwick, Manufacturers do
hereby declare the nature of our said 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 has for its object improvements in buttons which are made fro.n
glass and which are more compact than those now in use and though mounted with
metal shauks will allow of them being secured tightly up against the dress or
material without the liability of hanging in a loose manner which is generally the
case with shank buttons. We call our new button the "Girder Shank Button."
In order that our invention may be clearly understood and easily carried into.
practical effect we have appended hereunto a sheet of drawings from which we will
proceed to make known our invention. We would however have it clearly under-.
stood that we do not confine ourselves to the exact shape or pattern of the example
illustrated but only to the back or shauk portion thereof.
Figure 1 is a side view of our new button.
Figure 2 is a plan of the same button.
Figure 3 is a cross section through the shank B on the line 1. 2.
Figure 4 is a cross section at right angles to the section Figure 3 on line 3. 4 and.
also through the shank.
Figure 5 is an end view of the shank B and Figure 6 is a front view.
Figures 7 and 8 are alternative shapes for the shank B.
Figures 9 and 10 are sections of the metal I prefer to use for the shank B but
these may be modified with similar effect.
We make our button from glass in a heated or plastic condition when it is pressed
into moulds in the usual manner, but we so construct our moulds that the hollow a¹
is made straight across the back of the button A as shown upon the drawings, but
the edges or angles a² of this hollow may be rounded so as to make the eye of the
shauk still more accessible.
In manufacturing the buttons we prepare the shank B of any convenient section
of metal but preferably flat as shown and in a machine bend it to the formation
shown at Figure 6 when the depression 6' is clearly seen as well as the outwardly
turned out ends of the shank a³.
These shanks are imbeded in the plastic glass in the mould and cannot be
withdrawn without first breaking the button. It will be noticed at Figure 3
that the top or arch of the shank forms a part of the curve of the back of the
button and does not project therefrom and the recess or groove a¹ allows the
button to be sewn on the garment with the greatest facility. The shank may
however be modified in shape such for instance as shown by Figures 7 and 8 with
similar effect, and the section of metal we prefer to use are shown at Figures 9
and 10 but these may be varied.

page_text: 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 :-
The improvements in buttons made from glass or plastic material in moulds
consisting of the shank B embeded in the material A which is formed with the
hollow a substantially as herein set forth and shown in the drawings.
Dated this 24th day of June 1896.
