Gentleman do hereby declare the nature of this invention which has been com-
municated to me from abroad by J. S. Jones, of New York United States of
America 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 improved mechanism for sewing
together the "signatures" (folded sheets or sections) of books and also for forming
at the same time the channels for the "bands" by punching a series of openings
in the back of the signatures being sewed. I will proceed to describe this inven-
tion with reference to the accompanying drawings in which
Figure 1 represents a vertical section of the improved machine the section being

A, designates the frame of the machine to which are secured the bearings B for
the rock shaft C on which the oscillating arms D are mounted. In the outer ends
of these arms are formed bearings E for the gudgeons a (Figure 5) projecting from
plates 6 between which the signature carrier F is secured. In the example shown
in the drawing the plates b with the signature carrier F. are held in a vertical
position during the oscillations of the arms D by guide arm c mounted on the
gudgeon a the free end of which carries an antifriction roll d which engages a
stationary cam G secured to the frame A. The oscillating motion is imparted to

page_text: the arms D by a bell crank lever H pivotted to the frame at J' one end of which
lever engages a crank or arm J mounted on the rock shaft C: while its other end
is. held in contact by a coiled spring 8 (figure 5) with a cam K mounted on the
main shaft L. In operating this machine the signature to be sewed on, is placed
by the attendant on the carrier F, when the latter is in the position indicated in
dotted lines in Figure 1. By the mechanism above described the carrier is brought
to the position shown in full lines, in the said Figure 1 against the stop plate A'
running across the machine and under the combined punching and sewing
mechanism in which position it is automatically held by a spring bolt e Figure 4
which is mounted in the stop plate.
In this combined punching and sewing mechanism the needles f which usually
are pointed are blunt and act as punches passing through the signature and into
the opening g (Figures 3. 4 8 and 9) in the upper edge of the carrier F which acts
as a die by which means pieces are cut out from the back of the signatures (as
shewn in Figure 7) of sufficient size to form channels for the bands. A groove is
formed on each side of the needle above the eye in which grooves lies the needle
thread (which in this macbine forms the "band" for the book) so that when the
needle passes through the opening g in the carrier the said thread is protected
against chafing or being cut by the sharp edge of the opening g.
The needles fare secured to a needle bar M running across the machine and
to it are connected rods B¹ baving roller studs at their lower ends that engage
grooves in the cams K and N Figure 2 which are of a proper shape to give the
necessary motions to the bar M to cause the needles to pass up and down through
holes in the stop plate A¹ which holes serve as guides to the needles when making
their downward movement and as strippers when they move upward and out of the
signature, preventing the signatures from moving up with the needles.
The tension C¹ the take up D¹ and the shuttle E¹ are of common construction
and together with the needles f form an ordinary organized sewing mechanism but
the invention is not confined to the exact construction thereof, described.
To permit the trimming of the edges of the book after it is sewed it is necessary
that the shuttle thread should not extend to the outer edge of the book so as not
to be cut by the trimming operation and for that reason it is customary to slit the
back of the signature from its outer edges to where the two outer needles pierce it
so as to admit the shuttle thread. For this purpose two knives b¹ Figure 2 are
employed one at each end of the carrier F which pass into recesses in the stop
plate A¹ and cut the desired slits as the carrier strikes against the said stop plate.
As the stitch necessary for the work done by this machine will permit the
passage of the shuttle from either direction the motions of the shuttle carrier h is
so timed that it will go first one way as the needles come down and then back
when the needles are down a second time. To effect this the shaft O which drives
the shuttle carrier h is geared to the main shaft L in such a manner that the
former will make one revolution while the latter makes two revolutions. The
shuttle carrier h is connected by a pivot i to one end of a lever P which is pivotted
atj to an oscillating arm Q while its other end is pivotted to a sliding box which
is guided in the ways l. From the shuttle carrier h extends rods m m which are 4
connected to the oscillating arm by pivots n n situated on opposite sides of the
pivot ; while the connections between these rods and the shuttle carrier h are
formed by pivots n¹ n¹ situated on opposite sides of the pivot i which connects
the shuttle carrier to the lever P. If the rods m m are made of rigid material
only one such rod is required but if cords are used in place of the rigid rods both
are needed.
The oscillating arın Q is mounted on one end of a shaft o which has its bearings
in the standard R secured to the main frame while on the other end of this shaft
is secured a crank S from which projects a stud or roller p which engages the
slotted end of a lever T turning on a pivot q extending from the standard R. 5
Near the centre of the lever T is mounted a roller r which is engaged by a groove'

page_text: in the cam U mounted on the shaft O. It is obvious that as the cam U revolves
the lever T will oscillate on its pivot and impart a similar motion to the arm Q to
which the lever P is pivotted. This will cause the shuttle carrier which is
secured to the lever to pass back and forth in a straight line carrying the shuttle
through the loops formed by the sewing mechanism in the usual way.
In the example shown in the drawing the needles act as punches, making it
necessary to have dies to cooperate with them formed in the signature carrier.
These dies are formed by two parts or wings F1 F2 one of which is rigidly secured
to the plate b Figures 8 and 9 while the other is connected to the said plate by
the pivot a³.
.
Between the wings F1 and F' is a recess A³ in which the loops of the needle
thread are formed and through which the shuttle is carried in order to form the
stitch. When the shuttle has passed through the signature carrier. the latter is
opened in such a way that the shuttle thread which then lies in the loops of the
needle thread can be drawn out of the signature carrier as the needle thread is
drawn up taut by the sewing mechanism.
When this has been done the signature
carrier is again closed and is free to recede to its outer position to receive a new
signature. It must however be understood that it is necessary to make the wings
of the signature carrier movable only when dies for punching are formed in the
same. When ordinary needles are used both wings of the signature carrier may
be rigidly fastened to the plate b and sufficient space left between them to permit
the drawing up of the shuttle thread. The shuttle rests at each end of its stroke
to permit the back and forward motion of the signature carrier.
In Figures 8 and 9 are indicated the two positions of the signature carrier as
hereinbefore described. From the movable wing F2 projects an arm 63 which is™
acted on by a latch plate c³ secured to an arm d³ projecting from the needle
bar M. This latch plate is secured to the arm d³ by pins es working in slots f³ in
said latch plate. Figure 9 shows the signature carrier closed the needle punch
ready to descend and the latch plate resting on the arm 63. As the arm d³
descends with the needle bar the latch plate will slide inward out of the way of
the arm b³ until it has passed the said arm when it will again fall outward by its
own weight. Figure 8 shows the needle ascending, the latch plate in its outer
position acting on the arm 63 and the signature carrier opened in which position it
will remain until the arm d³ has reached the end of its upward stroke when the
arm b³ will slip off the lower edge of the latch plate and the signature carrier be
closed by the action of the spring g³ ready for a new operation.
The inner surface of the wing F¹ of the signature carrier is provided with
recesses a² into which the needles pass as they come down and which guard them
from the shuttle as the latter passes through the signature carrier (see Figure 3.)
One end of the needle thread which in this machine is the "band" to which the
signatures are sewed is secured to a block V and as the needle recedes after the
passage of the shuttle this thread is drawn taut by the take up D¹.
The signature or the carrier is attached to this "band" by the shuttle thread
and when the latter recedes the signature will not be carried back with it but
remain suspended from the band. Openings 62 (figures 3. 8 and 9) in the side of
the stop plate serve as thread guides through which the thread passes on its way
to the needle.
After the needles have performed their sewing operation and before the signature
carrier can move to its outer position it is necessary to release the latter by with-
drawing the spring bolt e.
This is done by a tumbler c² pivotted to the lower end of a rod d³ secured to the
needle bar M. Just before the needle bar reaches the end of its upward stroke the
rod d and the tumbler c³ will be in the position shewn in dotted lines in Figure 4..
As the upward motion of the needle bar continues this tumbler which is hield in
that position by the pin e² will press against the nose f³ on the spring bolt forcing
the same back and out of connection with the plate b of the signature carrier,"

page_text: leaving the same free to the action of the bell crank lever H. It will be under-
stood from the drawing that when the needle bar descends the tumbler will strike
the nose f and as it is free to turn in that direction it will fold in and not act on
the bolt.
