PROVISIONAL SPECIFICATION.
Improvements in Printers' Quoins.
We, FRED WAITE, of 32, Mount Pisgah, Otley, in the County of York,
Printers' Engineer, and WAITE AND SAVILLE, LIMITED, of Falcon Works, Otley,
aforesaid, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in printers' quoins and its object is to
provide a simple and readily adjustable quoin without loose parts and free from any
liability to slip or shake loose.
For this purpose we employ a guide piece having parallel guides between or
upon which guides a sliding or adjustable block is fitted. This sliding block is
adjusted within the said guides-to expand or contract the quoin-by means of a
screw fitting a female screw thread cut in the block. To keep the sliding block in
position in the guide piece the head of the screw operating the sliding block may
fie in a recess in the said guide piece and be so arranged that whilst it is perfectly
free to be rotated, to turn the screw, it is prevented from longitudinal movement in
relation to the guide piece. Or other means may be employed to confine the
screw longitudinally. The said screw may be tightened by means of a toggle lever
fitting holes formed in the head, or in any other convenient way.

COMPLETE SPECIFICATION.
Improvements in Printers' Quoins.
We, FRED WAITE, of 32, Mount Pisgah, Otley, in the County of York,
Printers' Engineer, and WAITE & SAVILLE, LIMITED, Falcon Works, Otley,
aforesaid, 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 :-
This invention relates to improvements in printers' quoins, and its object is to
provide a simple and readily adjustable quoin without loose parts and free from
any liability to slip or shake loose.
For this purpose we employ a guide piece having parallel guides between or
upon which guides a sliding or adjustable block is fitted. This sliding block is
adjusted within the said guides-to expand or contract the quoin-by means of a
screw fitting a female screw thread cut in the block. To keep the sliding block
in position in the guide piece the head of the screw operating the sliding block
may lie in a recess in the said guide piece and be so arranged that whilst it is
perfectly free to be rotated, to turn the screw, it is prevented from longitudinal
movement in relation to the guide piece.
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents a plan view of our improved quoin.
Figure 2, represents a side view, and Figure 3, an end view of the same.
Figure 4 represents a sectional view on the broken line a, b Figure 1.

page_text: Figures 5 and 6 respectively represent a separate plan view of the guide piece
and the sliding block.
The guide piece A is provided with parallel guides B, B between which the
sliding block C is fitted. The screw D fits the female screw thread cut in the
hole E through the block C and its head F lies in the opening or recess G formed
in the guide piece A, and the screw is thereby confined longitudinally. Holes H
are drilled through the head of the screw to admit the end of a lever to tighten
up the screw when the quoin is in position.
The underside of the sliding piece is preferably a little above the underside of
the guide piece so as to allow it to slide freely in or out when in position. And
to maintain the sliding block in this position in relation to the guide piece the
sliding block is provided with lateral lips J, J arranged to rest upon the top of
the guides B, B.
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 :
A printer's quoin consisting of a guide piece having parallel guides between, or
upon, which a sliding block is fitted adapted to be adjusted by a screw confined
longitudinally within said guide piece, substantially as herein shown and described.
Dated this 11th day of September 1894.
