This Invention relates to a new or improved machine or apparatus. for the
manufacture of buttons with thread backs and with flexible backs.
The novelty of this Invention consists in the simple construction and arrange-
ment of the machine, with the employment of a movable carrier having a limited
movement, and with double punches for the manufacture of buttons of varying
form and dimensions, known as buttons with thread backs and with flexible
backs.
The regular alternate motion or backward and forward movement of the carrier
in connection with the moulds which correspond with the punches suffices for the
complete manufacture of the button without there being any need to displace the
machine. By this arrangement the operation of working is carried out by the
machine itself, so that it can be worked by any one after a little practice.
The advantages obtained by this machine do not depend entirely in making
well finished buttons rapidly, but also in effecting a saving of the textile fabrics
employed, effecting at the same time greater solidity of construction than here-.
tofore.
The object desired was the combination of an apparatus capable of being used
in the manufacture of both kinds of buttons above described, and this is effected
simply by a change of the punches attached to the carrier, and of the dies or
moulds, or of the material used for the manufacture of the buttons, according to
the kind of button intended to be manufactured.
It will be evident that as many different moulds or dies and punches are
required as it is desired to obtain buttons varying in forms and dimensions.
The machine or apparatus consists of a frame which can be fixed to a bench
of any kind.
A rod is arranged to move up and down in guides on the frame, being actuated
by a weighted lever, and a carrier or holder is attached to the lower end of the
sliding rod for holding the punches, and the moulds or dies with their settings are
fixed to a support.

page_text: In order to effect the manufacture of a button with thread back all the com-
ponent parts are prepared before hand, and are placed on the die or mould of
the apparatus as follows:-
First, the top tissue; second, the top metal, after which the die or mould is
raised; third, the covering of the button; fourth, the cap; and fifth, the pasteboard
filling.
One pressure suffices to fix all these pieces; the thread back is then placed into
the left hand punch, after which one pressure suffices to set it on the body of the
button and to finish the latter completely.
For the manufacture of buttons with flexible backs, after having placed the
punches and moulds required for this kind of button on the machine, the pieces are
placed on the die or mould as follows:-
First, the tissue serving for the formation of the back; second, the metal which
is to form the back for the inscription, that is to say; the bottom portion of the
button; third, the filling, consisting of a pasteboard disc.
The first punch serves to ram in the filling by setting the lever in motion and to
turn up slightly the outer rim of the metal back so as to fit it by a second
.operation for the reception of the head of the button'; then are placed on the die or
mould the tissue for forming the upper portion of the button and the cap.
After having placed the second punch opposite the mould, one pressure with the
lever suffices to finish the button completely.
