A. NEW OR IMPROVED QUOIN AND SIDE STICK FOR LOCKING UP PRINTER'S FORMES
Year: 1885

page_text: I RICHARD SIMON of 300 Alfreton Road, Nottingham, Engineer, do hereby
declare the nature of my said invention for "A. NEW OR IMPROVED QUOIN AND
SIDE STICK FOR LOCKING UP PRINTER'S FORMES," to be as follows:-
My invention consists of a new or improved quoin and side stick made of metal
for locking up Printer's formes.
The quoin consists of a wedge shaped box made hollow so as to obtain lightness
and at the same time a small but positive amount of spring or elasticity which
helps to hold the quoin in its place when driven in by means of the shooting stick
used by Printers. The ends of this box are open, with the exception of a small
rib or web across to give strength.
The side stick consists of a wedge shaped casting two or more times the length
of the quoin but of the same width and having the two edges of the top or
inclined plane side grooved so as to permit the edges of the hollow box-wedge or
quoin to slide thereon. The central part between the two grooves acts as a guide
and prevents the quoin tilting.
I also make the side sticks in lengths of two four or more wedges cast end to
end so that large formes can be easily and quickly locked up by using 4 of my
new quoins or box-wedges.

Printers' Formes.
I RICHARD SIMON of 300 Alfreton Road, Nottingham Engineer, 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 a new or improved quoin and sidestick for locking up
printers' formes made of metal, preferably cast iron or steel and will be understood
by reference to the annexed drawings.
The quoin (Figure 1) consists of a wedge shaped box A made hollow as at B so
as to obtain lightness and at the same time a sinall but positive amount of spring
or elasticity which helps to hold the quoin in its place when driven in by means of
the shooting stick used by printers. The ends C of this box are open with the
exception of a small rib or web D across to give strength.
The sidestick (Figure 2) consists of a wedge shaped casting E two or more times
the length of the quoin but of the same width and having the two edges of the
top or inclined plane side grooved as at F so as to permit the edges of the hollow
box wedge or quoin A to slide thereon. The central part G between the two
grooves F, F, acts as a guide and prevents the quoin A tilting.
Figures 3 and 4 are side and top views respectively of the quoin and sidestick
together.
I also make the sidesticks in lengths of two, four or more wedges cast end to
end as shown at Figures 5 and 6 so that large formes can be easily and quickly
locked up by using four of my new quoins or box wedges.
Figure 7 represents a chase containing formes locked up with quoins and
sidesticks constructed according to my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The new or improved quoin and sidestick and the modification thereof as shown
in the annexed drawings.
