IMPROVEMENTS IN BOOK-BINDING, AND IN APPARATUS FOR THE PURPOSE
Year: 1884

page_text: I, ERNEST DE PASS, of 6S Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of said invention for,
IMPROVEMENTS IN BOOK-BINDING, AND IN APPARATUS FOR THE PURPOSE, to be as
follows:-
-
This invention relates to a new method of book binding and to apparatus for
the purpose, and it consists in binding all kinds of books, pamphlets, ledgers, and
the like, by means of bands or tapes of suitable material, without employing the
usual means of stitching the leaves with thread or wire.
The leaves of the book to be bound are placed according to its thickness, in a
gathering of from 1 to 2 centimeters (to of an inch) and perforated or cut by
means of a thin chisel, at a distance of about 21, millimeters (✓✓✓ of an inch) from
the back of the leaves, and this is done as many times as appears necessary for the
solidity of the binding. Through the perforations or cuts which have been so
forined the bands or tapes, preferably of linen or cotton, are passed by means of
an appropriate needle, hereinafter described; and these bands or tapes are of the
length necessary for attaching them to the cover of the book. After this operation
the back of the book is treated with glue and the further proceeding is the same
as hitherto.
An apparatus well adapted for the aforesaid purpose is illustrated in the
accompanying drawings, in which
Figure 1, is a front elevation,
Figure 2, a cross section, and
Figure 3 a plan.
The apparatus consists of a base p'ate B, on which a standard A, is bolted, this
latter supporting a fly wheel L. On the axis of this wheel are secured two
eccentric discs, one of which, m', placed behind and bearing the lever m, is in the
form of an arched triangle, and the other, a', placed in front, and bearing the guide
rod a, with a chisel b, at its lower end, is an ordinary round eccentric disc. In
front of the standard, and sliding upon a bar, is a sliding plate d, with a moveable

page_text: bar C, and an iron band f, the last named containing a certain number of incisions g,
formed at regular intervals apart. On the sliding plate d, just at the place where
the chisel descends upon it is a groove, extending its whole length, to receive a
wooden strip x, which is destined to secure the chisel against any direct collision
with the iron of the base plate. Under the bar c, and exactly against the projecting
angle, the gatherings of paper P, which are to receive the perforations or cuts,
are introduced, and are pressed upon the sliding plate by means of screws and
nuts k, k.
A revolution of the fly wheel L, causes the lever arm m, with its tooth n, at the
lower end, by descending, to disengage the corresponding pins o, o, attached to the
lever p, and at the same time the sliding plate to advance a step to one side, that
is, to push the next incision g, just under the descending chisel which, at this
moment, is cutting the gathering of leaves; by continuing the rotation, the lever
arm m, returns to its former position and, at the same time, tho chisel is withdrawn
from the gathering. The operation is repeated as many times as the gathering
requires perforations or cuts. After unscrewing the nuts kk, the presser bar c, is
raised by means of the spiral springs r, and the gathering is taken out, and a new
gathering inserted. In order to perform the same operation upon this new
gathering the fly wheel L, is turned, this time in the opposite direction, and so on.
Between the head of the chisel b, and a screw 8, in the guide rod a, a small
wedge t, is introduced which serves to counterbalance the possible shortenings of
the chisel, by grinding.
The distance of the perforations or cuts from the back of the gathering can be
varied by means of a small metal plate interposed between the chisel and the guide
rod a.
The breadth of the chisel is immaterial, about 3 to 5 millimeters (to
of an inch) is preferred.
A flat needle N, seen in figure 4, serves for drawing the bands or tapes through
the perforations or cuts of the gatherings. This needle may consist of two thin
steel blades brazed together for about "/rds of their length. Between the unbrazed
ends the band or tape is inserted, and is fixed therein by wax, glue, or other
suitable medium.
The apparatus herein described and illustrated can be modified by other
mechanical means, for instance, by attaching a chisel or a whole system of chisels
for the same purpose, on presser bars of paper cutting or paper folding machines,
or the like, or to lever contrivances.
Having now particularly described and ascertained the nature of said Invention,
and in what manner the same is to be performed I declare that what I claim is :
First. The method herein described of binding books of every description,
pamphlets, ledgers and the like in such a manner that the leaves of the books to
be bound are put together in gatherings of from 1 to 2 centimeters (+ to * of an
inch) in thickness and are perforated by means of a thin chisel, at a distance of
about 2 millimeters (16 of an inch) from their back as many times as the solidity
of the binding requires, after which operation bands or tapes of suitable material
and length are passed through the said perforations or cuts and the ends of same
attached in the usual way to the cover of the book, all substantially as herein
described.
Second. The apparatus herein described, and shewn in the drawings, for binding
books of all kinds by providing them with a certain number of perforations or
cuts, at regular intervals apart, destined to receive flat bands or tapes, said apparatus
consisting of a base plate B, in combination with a standard A, two eccentric
discs a¹, and m³, set in movement by the fly wheel L, the guide rod a, with
chisel b, the lever arm m, the sliding plate d with the presser bar c, and the lever p
with pins o, o, substantially as described.
Third. The modification of the above claimed apparatus consisting in attaching
one or several chisels to other mechanical means for instance to the presser bars

page_text: of paper cutting machines or to paper folding machines, or the like, or to lever
contrivances,
Fourth. The needle N, berein described, and shewn in figure 4, for drawing the
bands or tapes through the gatherings of paper which have been provided with
5 perforations or cuts near their back.
