COMPLETE SPECIFICATION.
Improved Machine for Stapling Cardboard Work, such as Boxes.
I, ADOLPH GREIFFENHAGEN, of 76, Dresdenerstrasse, Berlin, in the Empire of
Germany, Manufacturer, 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 :-
This invention relates to an apparatus to fasten staples or clamps in cardboard
work such as boxes in a rapid and certain manner in one operation or at one
stroke.
I attain the object of this invention by the mechanism illustrated by the
accompanying drawings in which:
Figure 1 Sheet No. 1 is a view in elevation of the machine,
Figure 2 Sheet No. 1 is a view in section thereof on the line a, a, Figure 1,
Figures 3 and 4 Sheet No. 1 and Figures 5, 6 and 7 Sheet No. 2 are views
showing details of construction, and
Figure 8 Sheet No. 2 is a perspective view of one of the staples or clamps.
Throughout the views similar parts are marked with like letters of reference.
The machine consists of a cast frame A which carries a plate B for the attach-
ment of the apparatus, and also has a projecting arm C provided with two holes
parallel with each other through which the tension rod D and the punch E pass.
The punch E is provided at its lower end or head with a piece a in which is a small
recess a adapted to serve as a support for that portion of the staple or clamp X
which is formed with triangular teeth a, e, the free leg of the staple or clamp X
being held by the two toggle levers & pivotted at 6° to the piece a and controlled
by springs fo
Pivotted to a plate B' mounted in the plate B are a pair of jaws g formed on the
ends of arms H the free ends of which are controlled by springs G attached to a
standard F. These jaws gare arranged so as to be capable of rotating in the
outer edges of an opening in the plate B and are situated exactly opposite to the
piece a. The arms H carry noses which engage with a pair of guide pieces d, d,
fulcrated on a triangular shaped plate D' carried by the rod 1, the said guide
pieces being arranged at an angle and pressed together at their apex by suitable
springs such as f.
The mode of operation is as follows:-
:-
A staple or clamp X is placed in the manner above stated between the toggle
levers b, and the cardboard box is placed upon the jaws g at the place where the
staple or clamp is to be fastened. Now by actuating the tension rod D, the
punch E is moved (together with the staple or clamp) towards the cardboard box.
At the same time the noses c, and consequently also the arms H are forced apart
by the action of the guide pieces d, d. By this means the inner edges of the
jaws g, 9. are drawn inwards in such a manner that the jaws form an angle into the
opening of which the triangular teeth., of the staple or clamp now pass. By
the pressure of the piece a, the teeth of the staple or clamp are forced through the
cardboard, and are caused by the inclined surfaces of the jaws g, g, to bend inwards.
At this moment the noses c, c, on the arms H, H, have reached the ends of the
guide pieces d, d, where they are furthest apart and are now violently pulled
towards each other over the ends of the said guide pieces by the special springs G, G,
so that the jaws g, 9, are shot back again into the plane of the table B, and thus
effect a firm and certain fastening of the teeth of the staple or clamp against the
cardboard.

page_text: To render the apparatus again ready for use, it is merely necessary to move the
guide rod D in the reverse direction which is conveniently effected by a suitable
spring such as L. This causes the guide pieces d, d, to come into contact with the
noses c. c, when the said guide pieces give way and allow the noses c, c, to pass
through them and when clear of them they are shot by the action of the springs f. 1,
back again into their normal positions, thus rendering the apparatus ready for
action again.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is:
(1.) The improved machine for stapling cardboard work such as boxes, substan-
tially as set forth.
(2.) A machine for fastening staples or clamps in cardboard boxes and the like
at one stroke, in which the staple or clamp is held by catches or toggle levers band
is pressed by a punch or plunger against the cardboard so that the staple or clamp
pierces the cardboard and its teeth are caused to glide or turn inwards along the
legs of the angle formed by the jaws g, g, so that by the sudden shooting back of
the said jaws, the teeth of the staple or clamp are completely turned or bent inwards
and pressed against the cardboard, thus effecting a perfectly secure and yet simple
and rapid fastening of the staple or clamp, as set forth.
(3.) In the machine as specified in the preceding claim, two guide bars d, d,
arranged at an angle with each other, along which the noses c, c, of the arms H
slide in such a manner that on the descent of the plunger, the arms are opened and
thereby the jaws g, g, are caused to form an angle with each other, which produces
the first preliminary bending of the teeth of the staple or clamp, whilst the final
fastening is effected on the noses c, c, becoming disengaged with the guide pieces
and the arms H, H, being brought together by the action of the springs G, G, as
set forth.
