I, CARL ERNST PREUSSE, of Leipzig-Anger-Crottendorf, in the Kingdom of
Saxony, German Empire, manufacturer do hereby declare the nature of this
invention to be as follows:-
This invention refers in general to machines for stitching together the sheets
of signatures and the like by means of threads, and in particular to that class
of said machines in which the working points of the needles are situated at
he upper ends of the same. My improvement in machines of said class relate
to providing the machine with an abutment-plate secured to a lever, and adapted
to be placed upon, or raised from, the working table, or upon or from the sheets
of signatures respectively, by means of said lever.
I have shown my improved machine in the accompanying drawing, in which:
Figure 1 is a side-view of the same,
Figure 2 is a vertical section through the abutment-plate afore mentioned,
Figure 3 is a plan of said plate, together with a portion of the lever holding
th: same, and
Figure 4 shows a signature provided with the thread.
The plate e, Figures 1, 2 & 3, is the abutment-plate and is held by the lever c.
The latter is supported by the standard i, and may be operated from a treadle
or the like by the mediation of the connecting rod g. The signatures to be
stitched are placed upon the angular table a, which is supported by the standard h.
The signature b is placed upon said table after the abutment-plate e has been
raised by the lever, c. Said plate is then lowered so as to rest upon the edge
of the bent signature, and the needles f (which may be operated by any desired
means) are then caused to pass through the signature. There are, of course,
suitable perforations in the table a as well as in the plate e (see Figure 2).
The thread d, which up to then was situated below the edge of the signature,
or at the lower or inner side of the latter respectively, is thus carried through
the signature in the manner indicated in Figures 2 & 4, when the signature may
be removed from the table a and replaced by a fresh one.

I, CARL ERNST PREUSSE, of Laipzig-Anger-Crottendorf, in the Kingdom of
Saxony, German Empire, manufacturer do hereby declare the nature of this
my 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 refers in general to machines for stitching together the sheets
of signatures and the like by means of threads, and in particular to that class
of said machines in which the working points of the needles are situated at
the upper ends of the same. My improvements in machines of said class relate
to providing the machine with an abutment-plate secured to a lever, and adapted
to be placed upon, or raised from, the working table, or- upon -or-from the sheets
of signatures respectively, by means of said lever.
I have shown my improved machine in the drawing left with the Provisional
Specification, in which-
Figure 1 is a side-view of the same,
Figure 2 is a vertical section through the abutment-plate afore mentioned,.
Figure 3 is a plan of said plate, together with a portion of the lever holding
the same, and
Figure 4 shows a signature provided with the thread.
The plate e, Figures 1, 2 and 3, is the abutment-plate and is held by the lever c.
The latter is supported by the standard i, and may be operated from a treadle
or the like by the mediation of the connecting, rod g. The signatures to be
stitched are placed upon the angular table a, which is supported by the standard h.
The signature 6 is placed upon said table after the abutment-plate e has been
raised by the lever c. Said plate is then lowered so as to rest upon the edge
of the bent signature, and the needles f (which may be operated by any desired
means) are then caused to pass through the signature. There are, of course,
suitable perforations in the table a as well as in the plate e (see Figure 2).
The thread d, which up to then was situated below the edge of the signature,
or at the lower or inner side of the latter respectively, is thus carried through
the signature in the manner indicated in Figures 2 & 4, when the signature may
be removed from the table a and replaced by a fresh one.
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:-
A machine for stitching together paper sheets of signatures and the like,
characterised by the employment of an abutment-plate adapted to be placed
upon or raised from the working table and in which the needles operate from
bottom to top substantially as described.
