A communication from H. THIER, of Königstein on the Elbe, in the Empire of
Germany, Button Manufacturer.
I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I. Mech. E. and Chartered Patent Agent do hereby declare the nature of this
invention to be as follows:-
1
The improved button herein described is unprovided with any covering of
cloth or woven fabric of any kind being merely a plate made of metal (preferably
of an alloy of nickel and zinc) or of celluloid covered with metal (preferably the
alloy just mentioned).
The buttons may be manufactured in two ways: a plate of the same sheet-metal
may be inserted into a cap of the same sheet metal and both connected together
by pressing or stamping in such a manner that the edges of the cap grasp the
plate inserted therein. In the solid plate or disc thus formed, the necessary holes
of the button are punched. The sharp edges resulting from this operation in
the front part of the button enter the body of the back part, while the edges
forming in the latter are rolled up so as to damage neither the thread used in
sewing the button on, nor the material to which it is sewn. Or a celluloid plate
or disc is covered with a metal plate or cap in the same manner as has been just
described, it being, however advisable in this case to form the edge, which closes
the joint separately in the shape of a ring connected with the two plane discs
(say one of nickel and zinc and the other of celluloid) by a suitable stamping
process. In this case the edge may be formed of some other metal if preferred
such as brass or tombac.
As the celluloid forms no sharp edges when punched out, it is only necessary in
this case to roll or turn up the sharp edges of the metal back; or, when the
perforation is made from the back, the sharp metal edges will be sunk into the
substance of the celluloid plate.
The buttons hitherto used in connection with underclothing have, as is well-
known, been either covered with or enveloped in canvas, or like material or have
had a piece of such material applied to them in a final operation. Such buttons
practice has shown to become damaged very soon in washing or mangling. The
metal or metal and celluloid button herein described has the great advantage over
those cloth covered buttons, that it is exceedingly strong and durable, and forming
practically one solid flat piece, it is not liable to be damaged in mangling; in
addition to which it has a better appearance, especially when provided with a
celluloid plate, which it does not lose through washing.

Improvements in Buttons.
A communication from H. THIER, of Königstein on the Elbe, in the Empire of
Germany, Button Manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The improved button herein described is unprovided with any covering of cloth
or woven fabric of any kind being merely a plate made of metal (preferably of an
alloy of nickel and zinc) or of celluloid covered with metal (preferably the alloy
just mentioned).
The buttons may be manufactured in two ways: a plate of the sheet-metal may
be inserted into a cap of the same sheet-metal and both connected together by
pressing or stamping in such a manner that the edges of the cap grasp the plate
inserted therein. In the solid plate or disc thus formed, the necessary holes of the
button are punched. The sharp edges resulting from this operation in the front
part of the button enter the body of the back part, while the edges forming in the
latter are rolled up so as to damage neither the thread used in sewing the button
on, nor the material to which it is sewn. Or a celluloid plate or disc is covered
with a metal plate or cap in the same manner as has been just described, it being,
however, advisable in this case to form the edge, which closes the joint, separately
in the shape of a ring, connected with the two plane discs (say one of nickel and
zinc and the other of celluloid) by a suitable stamping process. In this case the
edge may be formed of some other metal, if preferred, such as brass or tombac.
As the celluloid forms no sharp edges when punched out, it is only necessary in
this case to roll or turn up the sharp edges of the metal back; or, when the
perforation is made from the back, the sharp metal edges will be sunk into the
substance of the celluloid plate.
The buttons hitherto used in connection with underclothing have, as is well-
known been either covered with or enveloped in canvas, or like material, or have
had a piece of such material applied to them in a final operation. Such buttons
practice has shown to become damaged very soon in washing or mangling. The
metal or metal and celluloid button herein described has the great advantage over
those cloth covered buttons, that it is exceedingly strong and durable, and forming
practically one solid flat piece, it is not liable to be damaged in mangling; in
addition to which it has a better appearance, especially when provided with a
celluloid plate, which it does not lose through washing.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is :-
1. A button for washable clothing unprovided with a covering of woven material
consisting of a plate of metal (preferably an alloy of zinc and nickel) or of a plate
or disc of celluloid covered with a metal plate the two parts being united
substantially as specified.
2. A. button for washable clothing unprovided with a covering of woven material
consisting of a plate of metal (preferably an alloy of zinc and nickel) or of a plate
or disc of celluloid covered with a metal plate the two parts being united, the sharp
edges of the metal plate produced when the thread holes are punched being either
sunk into the substance of the celluloid plate or rounded or turned over sub-
stantially as specified.
