PROVISIONAL SPECIFICATION.
Improvements in Bookbinding.
I, WILLIAM WILSON, of 12 Johnstone Terrace, Edinburgh, Scotland,
Bookbinder, do hereby declare the nature of my said invention to be as
follows:-
My invention relates to that class of bookbinding which is technically known as
"bound work," and its object is to supersede the ordinary process of hammering
"laid on
the tape or cord (known as slips) "laced in or
the cover boards.
My invention consists in the application of a rolling pressure to the slips, after
"lacing in or "laying on," so as to press them into and render them flush
with the boards; this operation having been hitherto generally performed with the
hammer.
"
I mount two roller-segments by the ends in a frame and parallel with each other,
and with a plate between them, the whole being so geared together that the roller
segments turn towards each other, and the plate travels to and fro between and
with the segments.
The board of the book to be operated upon, is placed on the plate, the back
edge of the upper segment being cleared away to admit it, and, on the machine
being put in motion, the plate moves backward, carrying the board with it, and
subjecting the board and slips to the pressure exercised by the roller-segments,
which brought to bear up to the back edge of the board, forcing the slips into
the board.
By the use of this invention pressure can be so applied as to make the slips
perfectly smooth with the surface of the hardest board, with a saving of time, and
absence of all noise.

Improvements in Bookbinding.
I, WILLIAM WILSON, late of 12 but now of 5 Johnstone Terrace, Edinburgh,
Scotland Bookbinder, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
"
My invention relates to that class of bookbinding which is technically known as
"bound work," and its object is to supersede the ordinary process of hammering
the tapes (known as slips) "laced in
"laid on
or
the cover boards, by rivetting
the slips to the boards.
My invention consists in the application of a rolling pressure to the slips,
after "lacing in " or "laying on," so as to press them into and render them flush
with the boards; this operation having been hitherto generally performed with the
hammer.

page_text: According to my invention, I mount two roller segments upon suitable spindles
or axles, in a frame and parallel with each other, having a metal plate between
them, the whole being so arranged and geared together that the plate lies hori-
zontally between the segmental surfaces, and the plate travels to and fro' between
and with the segments.
The board of the book to be operated upon is placed upon the plate, the back
edge of the upper segment being cleared away to admit it, and, on the machine
being put in motion, the plate moves backward, carrying the board with it, and
subjecting the board and slips to the pressure exercised by the roller-segments,
until the back edge of the board is reached, forcing the slips into the board in its
progress. The motion of the rollers and plate is then reversed.
By the use of my invention the pressure can be so applied as to make the slips
perfectly smooth and level with the surface of the hardest board, with a saving of
time and absence of all noise.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawing, being an
elevation of my invention.
a is the frame of the machine. is the upper segmental roller, mounted
upon an axle at c in adjustable bearings. d is a hand lever whereby the roller b
is operated, and e is a balance weight. The roller bis formed to a longer radius
at than at g, so as to provide clearance for the introduction of the plate h, upon
which the board and tapes are placed.
The underside of the plate h is supported by the segmental roller k, which is
mounted upon an axle m carried by a cast iron bush n, the underside of which is
inclined so as to correspond with the inclined surface of the sliding wedge o. p is a
screw attached to the wedge o, having a hand wheel r, whereby the height of the
bush n and roller k can be regulated and the pressure adjusted. s is one of a pair
of toothed racks, shown by dotted lines, attached to the plate h. Into these racks
corresponding toothed segments, attached to the rollers, gear, so as to ensure
simultaneous movements to and fro.
By the use of my invention, pressure can be so applied as to make the slips
perfectly smooth, and level with the surface of the hardest board; also stouter
slips may be used, and a great saving of time is obtained.
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 :-
1. The improvements in bookbinding substantially as and for the purposes
described.
2. The improved method of attaching slips to the board in bookbinding
operations, substantially as and for the purposes herein before described.
3. The application and use of the improved apparatus, whereby pressure is
applied in substitution of and for the ordinary method of hammering, substantially
as and for the purposes herein before described and illustrated by the drawing.
