Improvements relating to Wire Staple Driving Machines.
1, FRIEDRICH REHWOLDT of the firm of Brehmer Brothers of Plagwitz
Leipzig in the Empire of Germany, Machinery Manufacturers 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 machines used for driving wire staples into or through
materials such as paper for binding together numerous sheets thereof for instance
in the so called wire stitching of pamphlets or the like and the object of the
present improvements is to enable such machines to properly drive such staples,
even when the same are made of very thin wire, into or through a great thickness
of such papers or other sheets to be fastened together, without bending the staples.
The improvements consist in adding to the machine piercing needles adapted
first to piece the sheets to be secured together and while inserted through the
holes made by them serve as guides for the two legs of the staple which is driven
by the driver while the said legs lie in grooves provided for that purpose along the
needles.
The legs of the staple are thus accurately guided through the holes mude
and are supported throughout their passage through the mass of sheets by the
needles previously driven therethrough so that by use of this invention either
thinner staples may be used or a greatly increased number of sheets or in other
words material of considerably greater resistance may be perforated and secured
by such staples.
Reference being made to the annexed drawing which illustrates this invention
as applied to the head of a staple driving machine,
Fig. is a vertical central section of such head.
Fig. 2 a similar section on line R R Fig. 1.
Fig. 3 a similar view showing the needles passed through the material to be
secured previous to the driving of the clamp or staple.
Fig. 4 is a section and Fig. 5 a section thereof on line S S Fig. 4 showing the
clamp or staple driven and mechanism in that position.
Fig. 6 is a horizontal section on the line N N Fig. 4.
Fig. 7 is an enlarged view of the needles the driver and the clamp or staple.
Fig. 8 is a section thereof on line OO Fig. 7, and
Fig. 9 is a section on line P P Fig. 7.
The needles bare fixed in a reciprocating driver a moved by suitable
mechanism in the head of the machine. These needles are guided in suitable slots
in the head of the machine as previously the legs of the staple have been guided,
but the needles themselves are also provided with longitudinal slots or guide
ways o o in which the legs of the staple i are guided when about to be driven and
during the full extent of the driving and in which also the lower end of the staple
driver is also guided.
The machine operates as follows; When the staple driver is in its highest
position and the needles are also in their highest position, the staple i either
placed ready made in the machine or produced therein is brought under the driver
and so that the legs thereof lic in the respective paths of the slots o o in the
needles bb. The needles are then driven and as they descend they pass about
the legs of the staple i, upheld by the block d, and further pass through the pile
of paper or other material to be clamped. When the needles have been driven
through this material, the staple driver in descending deflects and removes the
block and presses down the staple the legs of which move and are guided in the
slots o o in the needles bb until the clamp is fully driven, whereupon the needles bb
.

in the usual manner.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;
In a machine for driving wire staples, needles bb adapted to be driven into and
through the material into which the staple is to be inserted and to remain in such
material while the staple whose legs are guided in longitudinal slots in said needles
is driven, whereby the staple is supported through the material for the purposes
and with the advantages herein before described.
