PROVISIONAL SPECIFICATION.
An Improved Metallic Quoin for Locking-up Printers' Formes and
the like.
I, THOMAS ASHFORD, of 84, Railton Road, Brixton, London, S.W., Commercial
Traveller do hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable printers' formes to be more readily
locked-up than can be done by the methods now in use.
By this invention I provide two plain oblong triangular wedges, made of malleable
iron, steel or other suitable material, the two placed together forming one complete
quoin. For the larger sizes I make the wedges hollow, for two purposes, first and
principally in order that they should be as light as possible compatible with the
requisite strength; secondly to enable either of them to be easily driven out or
unlocked by inserting an iron shooting-stick (which I make for the purpose) against
the solid end of the wedge. The smaller sizes I make solid, as their extreme
narrowness (if cast hollow) would not permit sufficient room for the insertion of the
shooting stick. I obviate this by making a slot on the top portion of the wedges
which secures the lightness which would have been obtained if cast hollow, and
provides the requisite space for the insertion of the shooting-stick.
I purpose making these quoins in about eight different widths (each size
proportionately long) which will fully meet the requirements for all ordinary
purposes.
Dated this 13th day of November 1894.

COMPLETE SPECIFICATION.
An improved Metallic Quoin for Locking-up Printers' Formes and
the like.
I, THOMAS ASHFORD, of 84, Railton Road, Brixton, in the County of Surrey,
London, England, Commercial Traveller 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 :-
The object of this invention is to enable printers' formes to be more readily locked
up than by the methods now in use.
By this invention I provide two plain oblong triangular wedges, made of malleable
iron, steel, or other suitable material, the two placed together forming one complete
quoin. For the larger sizes I make the wedges hollow for two purposes, viz., first
and principally in order that they should be as light as possible compatible with
the requisite strength; secondly, to enable either of them to be easily driven out
or unlocked by inserting an iron shooting stick (which I make for the purpose)
against the solid end of the wedge. The smaller sizes I make solid, as their extreme
narrowness would not permit (if cast hollow) sufficient room for the insertion of the
shooting-stick. I obviate this by making a slot on the top portion of the wedges,
which secures the lightness which would have been attained if cast hollow, &
provides the requisite space for the insertion of the shooting-stick.

page_text: I purpose making these quoins in about eight different widths (and proportionately
long) which will fully meet the requirements for all ordinary purposes.
I make the longer sizes of these quoins with an occasional rib across the hollow
portion of the wedges, according to the length required, for the purpose of securing
the necessary strength.
They are mostly made of the same angle, for the purpose of rendering them
interchangeable; that is to say, if two wedges of the same width were too narrow
or too wide, when placed together, to fit the required space, another wedge of a
different width can be applied, so that any ordinary space can be quickly & easily
fitted, without padding with leads, reglets, or furniture of any kind. By using two
wedges of different angles these quoins can be locked-up against an ordinary
tapering sidestick.
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. An interchangeable hollow metallic quoin, that will fit any ordinary sized
space, without padding with leads, reglets, or furniture of any description.
2. A hollow metallic quoin that will lock-up equally as well when placed against
a flat or a tapered surface.
