ERNEST DE PASS, of 68 Fleet Street, in the City of London, Follow of the
Institute of Patent Agents, IMPROVEMENTS IN BOOK-BINDING AND IN APPARATUS
THEREFOR, Communicated to me from abroad by Friedrich Wilhelm Schwarz, of
Offenbach-on-the-Main, in the German Empire.
This invention relates to a new method of and apparatus for binding books,
pamphlets and tho like. It consists in binding such articles 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 5 centimetros, and perforated by means of a thin chisel at
a distance of 2%, millimeters from the back of the leaves, and this is done as
many times as appears necessary for the solidity of the binding. Through the
cuts which have been formed in the said manner the bands, preferably made of
linen or cotton, are passed by means of an appropriate needle; and these bands are
of such a length as is 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 consists of a base or base-
plate on which a standard is bolted.
This latter supports a fly-wheel which is
put in movement by hand. On the axle of this fly-wheel is secured an eccentric
disc which raises and lowers a guide-rod which carries, at its lower end, a chisel
fixed thereon by a screw.
The gatherings of paper are placed upon a board, and are provided with suitable
cuts. On one side of this board a presser-board is secured by a moveable hinge
joint, and this presser-board carries on one sido, and on its whole length, an iron
band containing a certain number of slots or incisions, and near the binge-joint is
a spring which retains the presser board upright during the moment the paper is
placed on the gathering-board. A moveable rule is provided to guide the gatherings
of paper. A steel plate engages in an elastic and indented tongue of steel attached

page_text: to the gathering board and holds the presser board fast upon the gathering of
paper. The paper is laid upon the board so that its back is placed under the slots
or incisions of the iron band and held fast in position by the presser board which
can be maintained higher or lower by means of a regulating screw according to the
thickness of the gathering. After this, the gathering-board is laid upon the baso
plate, and by turning the wheel the chisel makes a cut through one of the slots or
incisions in the iron band and through the gathering, and this operation is repeated
with the other slots or incisions. In order to regulate the position of the
gathering board a small notch or incision is made at its edge opposite the centre
of every one of the slots or incisions of the iron band, which incisions must
correspond with a small projection contrived on the standard.
The needle which serves to pass the tape through the cuts in the gatherings
consists of two thin steel plates brazed together for about /, of their length. The
tape is put between the two unbrazed ends and fixed between them by wax, glue,
or the like.
