Improved Means for Locking and Justifying Type.
I, THOMAS JONES of 12 Garnons Street, Carnarvon, Printers Overseer, do
hereby declare the nature of this invention to be as follows:-
My invention is devised with a view to effect an improvement upon the systems
which at present obtain for locking and justifying type for printing purposes
generally and which said improved device, I propose to term the quod bar self-
locking chase. Hitherto it has been customary to effect the locking by means of a
fixed rectangular iron frame termed a "chase." For instance assuming a frame
or "chase" is employed size 10 inches by 8 inches and the type for printing a card
or page size 5 inches by 6 inches has to be locked or justified therein the difference
between the two dimensions above stated must be made up or filled up with what
is known as printer's furniture and the locking be effected by tapering pieces of
wood known in the printing trade as quoins on side and bottom of matter, small
wedges being then employed to tighten the whole up. This operation is repeated
in every case; and, the filling up &c. must be replaced by another packing to suit
the difference between the size of matter and the inside measurement of the frame
or "chase."
Now, in accordance with my invention, and which I have also illustrated in the
accompanying sheet of drawings, I dispense with the necessity of filling up and
finding and fitting in wedges &c., all as above; the device according to my said
invention being contrived so as to act as an extensible and diminishable frame to
suit any size of matter. That is to say in accordance with my improvements it is
only necessary to close the "quod bars "hereinafter identified to the matter and to
secure the ends of said bars by means of screws and nuts or equivalents as shewn
in accompanying drawing adapted to the grooved outside framing of the "chase."

said spanner to be used for operating the locking nuts and screw H shown also in
section Figure 3 and the box key (portion of Figure 4) being employed to tighten
and release the nuts and screws when required; I is a movable bar which on the
nuts H being operated locks the type securely in position in the rectangular space
indicated by the dotted lines d. Figure 1. Of course as it will be readily under-
stood the number of the overlapping adjustable sliding bars, could be increased
when required, thus, for instance, say, a form of 8 or 16 pages, having to be
printed, said bars C. C. D. D. could be introduced between the
pages
&c.
A great saving of time is effected by means of my invention secing that by
means thereof, while, as hitherto, the compositor is looking for the necessary fillings
and locking apparatus to make the matter ready for machine, a job could be
worked off during that time by the aid of any invention and since change of jobs
on machine, takes place so often in a day, the time gained for men and machines
will be very great.
Dated this 21st day of March 1892.

Improved Means for Locking and Justifying Type.
.I, THOMAS JONES of 12 Garnons Street, Carnarvon, Printers' Overseer, 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:-
My invention is devised with a view to effect an improvement upon the systems
which at present obtain for locking and justifying type for printing purposes
generally, and which said improved device I propose to term the quod bar self
locking chase.
Hitherto it has been customary to effect the locking by means of a fixed
rectangular iron frame termed a "chase." For instance, assuming a frame or chase
is employed, size 10 inches by 8 inches and the type for printing a card or page
size 5 inches by 6 inches has to be locked or justified" therein the difference
between the two dimensions above stated must be made up or filled up with what is
known as printers' furniture and the locking be effected by tapered wood on bottom
and side of matter, small wedges being then employed to tighten the whole up.
This operation repeated in every case; and, the filling up &c. must be replaced
by another packing to suit the difference between the size of matter and the inside
measurement of the frame or "chase."
Now, in accordance with my invention and which I have also illustrated in the
drawings filed with the Provisional Specification of this my said invention, I
dispense with the necessity of filling up and finding and fitting in wedges &c.; the
device which I employ, being contrived so as to act or serve as, a frame capable of
being either extended or reduced to suit any size of matter. That is to say. In
accordance with my improvements, it is only necessary to close the "quod bars"
hereinafter identified, to the matter and to secure the ends of said bars by means
of screws or nuts or equivalents as shewn in the drawings, adapted to the grooved
outside framing of the "chase."
Referring to the drawings,
Figure 1 is a plan view of my improved device;

Figure 2, cross section on line a, Figure 1.
A, A are the two ends of the frame or chase. B, B, the sides thereof;
C, C., D, D, overlapping sliding adjustable bars. E, E, E, E. grooves or slots
in A A, B, B. F, adjusting nuts and screws for fixing the bars C, C., D, D in
position as required. G (Figure 4) shews a combined spanner and box key for
operating by means of the spanner portion the locking nuts and screw H. The
box key portion of the device Figure 4 being employed to tighten and release,
respectively, the nuts and screws F, when required. I is a movable bar, which on
the nuts being operated, locks the type securely in position in the rectangular
space indicated by the dotted lines d, Figure 1. Of course, as will be readily
understood, the number of the overlapping adjustable sliding bars could be increased
when, required; thus, for instance, say a "form" of 8 or 16 pages having to be
printed, said bars, C, C, D, D could be introduced between the pages &c.
A great saving is effected by means of my invention seeing that by its use
instead of as heretofore the compositor having to look for the necessary fillings
and locking apparatus to make the matter ready for machine, the time so occupied
is saved, as now, under my improvements during such time a job could be worked
off and seeing also that change of jobs on machine occurs so often during a day,
the time gained for men and machines, will consequently, be considerable.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and what manner the same is to be performed, I declare that what I
claim is:
The time and labor saving means to be employed for locking and justifying type
substantially as herein described and shewn.
