PROVISIONAL SPECIFICATION.
Improvements in and connected with Buttons.
I, ALFRED WILLIAM KNIGHT, of Cuckñeld, in the County of Sussex,
Ironmonger and Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to buttons and to means for securing the same.
A button constructed according to my invention is adapted to be secured by
what is known as a bifurcated rivet and for this purpose it is provided with a
central depression or boss forming a hollow shank.
In the bottom of this depression are formed holes having between them a
central bar and two recesses to receive the bent over ends of the rivet when
clinched in the same manner as described in the Specification of my former Letters
Patent No. 1151 of 1894.
In applying my invention to small buttons where there is not room to clinch the
ends of the rivets outwards, I form the central bar with recesses in which the
enda of the rivet when clinched inwards will fit.
In some cases I form the rivet in one piece with the button, that is to say,
1 provide the back of the button with two prongs.similar to the prongs of a
bifurcated rivet and in securing buttons of this kind I make use of washers
or "boss-caps" of the kind described in the Specification of my Patent before
referred to.

Improvements in and connected with Buttons.
I, ALFRED WILLIAM KNIGHT, of Cuckfield, in the County of Sussex,
Ironmonger and Engineer, 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 relates to buttons and to means for securing the same.
A button constructed according to my invention is adapted to be secured by
what is known as a bifurcated rivet and for this purpose it is provided with a
central depression or boss forming a hollow shank.
In the bottom of this depression are formed holes having between them a central.
bar and two recesses to receive the bent over ends of the rivet when clinched in:
the same manner as described in the Specification of my former Letters Patent
No. 1151 of 1894.
In applying my invention to small buttons where there is not room to clinch the
ends, of the rivets outwards, 1 form the central bar with recesses in which the'
ends of the rivet when clinched inwards will fit.

page_text: To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a plan; and,
Figure 2 is a section of a trousers or like button constructed according to my
invention:
Figure 3. is an elevation; and,
Figure 4 is a plan of the bifurcated rivet:
" phenoty
Figure 5 is a section shewing the button secured to a piece of cloth or like
material:
Figure 6 is an elevation of a punch employed to apply my buttons; and,
Figure 7 is a plan view of the operating face of same:
Figure 8 is a section of a modified form of the trousers or like button shewn in
Figures 1 and 2:
Figure 9 is a plan of the underside of same; and,
Figure 10 is a section shewing the button applied to a piece of fabrio :
Figures 11 and 12 are a vertical section and a plan respectively shewing the
modification as applied to a boot button; and,
Figure 13 is a section showing this button applied to a piece of leather or
the liko :
•
Figures 14, 15 and 16 are corresponding views to Figures 11, 12 and 13 but
abowing a trousers button constructed 'similarly to the boot button illustrated in
the latter figures.
The various figures are drawn to an exaggerated scale.
Similar letters of reference indicate similar or corresponding parts in the several
figures.
a.is my button, and b is the bifurcated rivet for securing the same.
Figures 1, 2 and 5, is the central depression or boss of the button a forming
a hollow shank; d,d are the holes in the bottom of the depression ; e is the
central bar between the said holes, and f, fare the two recesses to receive the bent
over ends of the rivet b, Figures 3 and 4, when clinched as clearly shewn in
Figure 5.
In order to secure a button of this construction to a piece of fabric, the
prongs of the rivet bare first passed through the fabric h, Figure 5, and theu
through the holes d, d into the depression or boss o of the button a.
T'he prongs
of the rivet bare then clinched or turned over in the manner shewn, by means of
the punchi, Figures 6 and 7, the use of which punch is illustrated by the dotted
lines in Figure 5.
.
In the arrangement illustrated in Figures 8 to 10, the bottom of the hollow
boss o is entirely open and the front of the button a is provided with an outer
shell forming a passage to receive, the ends of the prongs of the rivet b, as
shewn in Figure 10.
The arrangement of boot button shewn in Figures 11 to 13. is similar to the
trousers button just described except that the button and its boss are solid and the
passages for the prongs of the rivet bare made through the same, the ends of
the prongs when securing the button being turned into a recess m in the top of the
button as shewn in Figure 13.
The trousers button illustrated in Figures 14 to 16 is constructed in the same
manner as the boot button just described and therefore needs no description.
Instead of applying my buttons by hand with the aid of a punch as hereinbefore
described they can be easily and rapidly applied by means of a Thomson's
automatic feed clinching machine.
Having now particularly described and ascertained tho nature of my said inven
tion and in what manner the same is to be performed, 1 declare that what I
olaim is:
:
1. A button having a central depression or boss adapted to receive the bent
over ends of a bifurcated rivet when clinched substantially as, and for the purpose,

page_text: hereinbefore described and illustrated in Figures 1 to 5 of the accompanying
drawing.
2. The modified form of button hereinbefore described and illustrated in.
Figures 8 to 10 of the accompanying drawing.
3. The modified forms of buttons herein before described and illustrated
respectively in Figures 11 to 13, and Figures 14 to 16 of the accompanying
drawing.
