RESEOSZ
I, EUGENE FLORIAN CONE, of No. 37 Grand Street, Hartford, in the State of
Connecticut, United States of America, Tool Maker, do hereby declare the nature
of this invention to be as follows
--
In the specification of Letters Patent of Great Britain, granted February 11th 1879, to
David McConnel Smyth, No. 538, the signatures are described as being laid in succession
upon arms marked e of the drawings that are revolved around progressively and raised
to bring the signatures up to the place of sewing and then drawn down and out of the
sheet after it is sewed. In this class of book sewing machines there is also a gauge
upon the arm to determine the position of the folded signature lengthwise upon said
arm. In some book sewing machines all the needles and the loopers act in one direc-
tion and tend to move the sheets along further towards the ends of the arins.
My invention relates to the combination with the arms upon which the sheets are
held while being sewed, of a fence or gauge against which the heads of the folded
signatures are received, so that they are sustained and kept in the proper positions
relatively to the sewing mechanism, and there is no risk of the head or top edge of the
book being irregular.
The sheet carrying arm is provided with an end gauge or clip, and this clip may be
fitted to slide upon said arm or it may swing as described in the specification of said
patent No. 538 (79). After the sheet or folded signature is laid upon the said arm this
gauge or clip determines the position of the head and holds the sheet until it is brought
around to place and raised up to the sewing mechanism. In this operation the sheet
carrying arm comes close to the bend or angle at the end of a fence.
This fence is in the proper position for the heads of the signatures to come against the
same, and the fence is supported in any suitable manner, preferably by a standard
screw and slotted plate, so that the fence itself may be moved to occupy the proper
place. A cam piece may extend below the plate with the fence riveted to the plate,
but these parts may be made separately and held by the one screw. The cam piece
is inclined so that the gauge or clip is swung or slid as the arm is raised, but the
signature itself cannot move end wise upon the arm during the sewing operation
because the head of the folded signature at the back of the arm comes against the fence

page_text: and is kept in position thereby, and the heads of the previously sewed signatures are
against said fence, so that they cannot be displaced or become irregular in consequence
of the pull of the threads, under the action of the loopers or needle, being endwise of
the folded signatures.
In some book sewing machines the arm and the gauge draw down out of the signature
before the sewing operation is completed, and the pull of the threads in sewing being
end wise, the signature is not always sufficiently supported by the one side of the
folded head that comes against the fence. This is especially the case with thin paper.
To guard against this difficulty I make use of a spring that is fastened at one end to
the slotted plate before referred to and the other end rests upon the top of the arm at the
end of the folded back of the signature as said arm brings the signature up to the place
when it is sewed, hence this spring remains as a gauge to prevent the signature being
moved end wise after the arm and gauge have been drawn down out of the signature

I EUGENE FLORIAN CONE, of No. 37, Grand Street, Hartford in the State of
Connecticut, United States of America, Tool Maker, do hereby declare the nature of
the said invention for "IMPROVEMENTS IN BOOK SEWING MACHINERY," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
In Letters Patent of Great Britain No. 538, granted to David M. Smyth, Feb. 11'
1879, the signatures are laid in succession upon arms that are revolved around
progressively, and raised to bring the signatures up to the place of sewing, and then
drawn down and out of the sheet after it is sewed. In this class of book sewing
machines there is also a gauge upon the arm to determine the position of the folded
signature lengthwise upon said arm. In some book sewing machines all the needles
and the loopers act in one direction, and tend to move the sheet along farther towards the
end of the arms.
My invention relates to the combination, with the arms upon which the sheets are
held while being sewed, of a fence or gage against which the heads of the folded
signatures are received, so that they are sustained and kept in the proper positions
relatively to the sewing mechanism, and there is no risk of the head or top edge of the
book being irregular.
In the drawings, Figure 1, is a plan view showing my improvement.
Fig. 2, is
an elevation of the fence and a portion of the sheet supporting arm, and Fig. 3, is a
plan of the arm and clip.
The arm e is the same as shown in the aforesaid patent, and the mechanism for sewing
is of any desired character, such, for instance, as that shown in British Letters Patent
No. 2277 of May 24, 1881 and the same does not require to be represented.
The arm e is provided with the end gauge or clipf which clip may be fitted to slide
upon said arm as shown, or it may swing as shown in said patent No. 538 (79). After
the sheet or folded signature is laid upon the said arm, this gage or clip determines
the position of the head and holds the sheet until it is brought around to place and raises
up to the sewing mechanism. In this operation the arm e comes close to the bend or
angle 3 at the end of the fence 2. This fence 2 is in the proper position for the heads
of the signatures 4 to come against the same, as seen in Fig. 1, and the fence is
supported in any suitable manner. I have shown a standard 8 on the book sewing
machine, a screw 7, and slotted plate 12, so that the fence itself may be moved to
occupy the proper place. The cam piece 10 is shown as extending below the plate 12,
with the fence 2 riveted to the plate 12; but these parts may be made separately and
held by one screw 7. The cam piece 10 is inclined so that the gage or clip f is swung
or slid as the arm e is raised; but the signature itself cannot move end wise upon the
arm during the sewing operation, because the head of the folded signature at the back
of the arm comes against the face 2 and is kept in position thereby, and the heads of

page_text: the previously sewed signatures are against said fence 2, so that they cannot be displaced
or become irregular in consequence of the pull of the thread under the action of the
loopers or needles, being endwise of the folded signatures.
In some book sewing machines the arm e and the gage draw down out of the
signature before the sewing operation is completed, and the pull of the thread in
sewing being endwise, the signature is not always sufficiently supported by the one
side of the folded head that comes against the fence 2. This is especially the case with
thin paper.
To guard against this difficulty, I make use of the spring 15, that is
fastened at one end to the plate 12, and the other end rests upon the top of the arm e
at the end of the folded back of the signature as said arm brings the signature up to
the place where it is sewed; hence this spring remains as a gage to prevent the
signature being moved endwise after the arm and gage have been drawn down out of
the signature.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
1st. The combination with the signature holding arm, in a book sewing machine, of
the stationary fence or gago against which the heads of the folded and sewed signatures
rest while the sewing is being performed, substantially as set forth.
2nd. The combination with the signature holding arm, of the fence against which
the heads of the folded signatures are received and the spring 15, the end of which is
in line with the fence, for the purposes and substantially as set forth.
