COMPLETE SPECIFICATION.
Improvements in the Furniture of Printers' Chases.
We, WESLEY PETTY, of the Whitehall Printeries, Leeds, printer and JOHN
EDWIN TAYLOR of 16 Garfield Terrace, Bramley, Leeds in the county of York,
letterpress printer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
form or
any
Our invention relates to improvements in chase furniture applicable to
type of chase, and has for its objects the better manipulation of the chase in locking
up, and also increased security in moving the same. In locking up chases fitted
with the ordinary furniture hitherto known and used, of large size, such for instance
as double demy, or larger posters, containing a mass of metal type, the centre portion
thereof is frequently found to drop, while the sides are quite safe. According to our
invention we overcome this difficulty, and obviate its disadvantages, by so arranging
the chase furniture as to support the central portion of the mass from the sides, or
safest part of the forme, employing "side bars" and "reglets" made of wrought
iron, or other suitable metal which can be used in any ordinary printers chase
without requiring the expenditure of more time or trouble than is necessary to lock
up a forme in the usual way. The adoption of the improved furniture according to
our invention also prevents marking,"
," which may be caused by the rising of
material that should be lower than the type; and is also especially applicable for
formes in which the type lines are set diagonally, and for small type formes in which
it is advantageous to lock up in one section, instead of dividing into two or four,
such for instance as time-tables, or the like, having very little margin around
the pages.
In the following description of our invention, and the manner in which it is carried
out, reference may be had to the accompanying sheet of drawings.
"
Figure 1 represents a side bar, two of which are intended to be used in the
preparation of each forme, one close to the wood furniture of the chase, and one
close to the side-stick upon the opposite side thereof, used (with the footstick) for
locking up the forme in such a manner that the higher part a and the lower part b
are exactly opposite to each other; and Figure 2 represents the style of "reglet'
employed by us, in which the small projecting part c upon each end is made so as to
engage with, and rest upon the depressions 6 on each of the side-bars, thus forming
a support for the central mass of the forme. A similar "reglet," with the lower
portion d placed uppermost is arranged so that the projections c fit into and under
the part indicated by a on the side bars shewn by Figure 1, this arrangement
effectually preventing "marking" or "springing" as hereinbefore referred to.
Figure 3 shews the method of using the improved side bars and "reglets," the
dotted lines representing the chase furniture, side and footsticks used in locking up a
forme.
Two, three, or more "reglets" may be employed, resting upon the bars as before
described, and two, three, or more under the bars, according to the requirements of
the case, subject to the discretion of the person whose duty it is to lock up the
forme, this operation being accomplished in the usual manner, but by the employment
of the side bars and "reglets" according to our invention, said forme is rendered
perfectly rigid, and may be moved with perfect safety.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is,
First. In chase furniture used in letterpress printing the employment of side bars,

page_text: Figure 1, and reglets Figure 2, substantially as and for the purposes herein
described with reference to the accompanying drawings.

"
Second. In locking up a forme the employment of two, three, or more "reglets
shewn by Figure 1, with projections c resting in depressions 6 on the side bars
shewn by Figure 2, and two, three or more similar "reglets placed under said
side bars, substantially as and for the purposes herein described, and as shewn by the
drawings.
