COMPLETE SPECIFICATION.
Process and Apparatus for the Manufacture of Cards Armed with
Metallic Staples for Holding Buttons or Studs.
1, JACOB PROSKAUER, Manufacturer, of Schmiedestrasse, Leipzig-Plagwitz, in
the Kingdom of Saxony, do hereby declaro 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 :-
This invention has for its object, to provide sheets of cardboard with clamps or
metallic staples suitable for holding buttons or studs.
The clamps are formed from wires and then attached to the said button holder
cards, the required length of wire being first out off and then formed into a staple
or clamp by means of suitable dies, after which the staple is connected with the
card by means of a separate card plate.
.
In the accompanying drawings,
Figs. 1,and 2 are vertical sections of an apparatus embodying my invention;
Fig. 3 is a partial front view of the same;
Fig. 4 is a horizontal section along line R-R of Fig. 1 ;
Fig. 5 is a plan;
Fig. 6 is a horizontal section along line S-S of Fig. 2;
Figs. 7 and 8 are separate views of the lower die or matrix ;
Figs. 9 and 10 are separate views of the bending plate;
Figs. 11 and 12 and 13 are diagrams of the entire machine representing the
movable parts. at consecutive stages of operation;
Figs. 14 to 19 are enlarged views of the principal working parts at various
etages of operation; and
Figs. 20 and 21 represent a finished button holder card armed with metallic
clamps or staples.
The principal parts of the staple-forming and staple-driving mechanism are the
stamp or upper die A, the matrix or lower die B, and the mechanisms D and F for
operating the said dies, the former comprising a treadle and a grooved lever or
cam C, and the latter a spring f.
The die and the matrix are provided with grooves a for the wires arranged in
pairs, and with ridges or projectious & separated from each other by blanks c, as
shown by Figs. 7 and 8.
The staple wire t is drawn off suitable bubbins or drums by means of feed
rollers H, and pushed into the feed channels d which also serve to keep the wire t
in a straight line.
T
At the end of the feed channels the wires are cut off by means of a knife S
set in motion at the required inoment from the cam shaft g by means of cam
levers G.
The pieces of wire which have been pushed into the grooves a of the die and
matrix are subjected to pressure and moulded into the desired shape by driving the
die A and matrix B against each other intermittently, as indicated by Figs. 15
and 16. The number of nicks formed in the back of each staple corresponds to the
number of buttons to be held.
The same operation serves to bend the staple wire at the ends k, as shown
by Fig. 17, the matrix being finally pushed down by the die until the spindle
supporting the same is stopped by a retaining hook, which then holds the
matrix B in its lowest position, as indicated by Fig. 12.

page_text: While the matrix occupies this position, a plate P (Fig. 10) carrying on its
underside the sheet of cardboard to be armed with wire clamps, is inserted
between the die A and the matrix B, after which the retaining hook his released,
60 that the matrix may be jerked upward by the spring f, and the ends k, k, of the
clamp driven through the card K (Figs. 13 and 19) after which the concave
bending surfaces o, o, which may be arranged in various ways, bend the ends of the
wire down, so as to establish a firm connection between the card K and the
clamp t. As shown by Fig. 20, the staples or clamps are arranged in pairs parallel
to each other, so that each pair may hold a series of studs to the right and left of
their shanks.
According to the number of the grooves or recesses formed in the face of the die
and of the matrix, more or less clamps or staples may be applied to the card
simultaneously, and the shape and construction of the various parts, and the
arrangement of the entire machine may, of course, be modified according to the
size of the staple card and the special purpose for which it is intended. Cards
armed with metallic staples as described, may be used for holding various kinds of
buttons and studs.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The process for the manufacture of cards or sheets armed with wire-staples or
clamps for holding buttons or studs, which consists in forming or arranging the
said staples or clamps in pairs as parallel rods provided with intermediate bends or
nicks, driving their ends through the card or sheet and clinching them.
2. A staple press adapted to operate substantially as described with reference to
the drawings.
