PROVISIONAL SPECIFICATION.
Improvements in Quoins and Side Sticks for Use in Printing Chases
and Machine Beds.
We, EDWARD THOMAS CLEATHERO, of 16 Tollington Place, London, N. and
EDMUND WILLIAM HORNSEY WALKER, of 31 Bouverie Street, London, E.C.
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of constructing quoins and side
sticks for use in printing chases, and machine beds, the object of the invention
being to produce a simple and safe adjustable quoin and one which will have great
strength of resistance when being driven up or tightened within the chase.
In carrying our invention into effect in one convenient manner, we make our
quoins preferably in pairs in the form of two oppositely-shaped wedges arranged
so that the two inclined surfaces meeting form or produce two parallel surfaces on
the outer faces. We cause one wedge or quoin to slide by the side of the other so
as to expand or contract upon the forme within the chase by providing a number
of serrations or rack-like teeth within the upper surface of the inclined face, and a
corresponding number of recesses or serrations in the opposite face. We employ
an improved key or fork for manipulating the two sliding wedges arranged in such
a manner that one key or pin of the fork enters within one recess on one of the
wedges, while the other pin or limb of the key enters a recess upon the other
inclined face. Upon the key being turned, one wedge is driven over the other,
and a closer contact is made between the chase and the forme; to release the
wedges or quoins the key or handle is turned in the opposite direction.
We prefer to form our quoins with the serrations on each side so that the key
can be employed to move the wedges in either directions, one wedge being thrust
in one direction and the other being thrust forward in the opposite direction and
sliding one upon the other.
Instead of making the serrations or recesses with open mouths, or with entrances
from the front or the face of the inclined part of the wedge, we sometimes make a
number of holes instead, the holes being formed suitable for the leg or pin of the
key to enter, one pin or one leg of the key entering in one hole upon one of the
wedges while the other enters upon the companion side-hole on the other wedge.
When making our improved side-sticks or providing for great lengths within the
chase we may use short quoins for locking purposes, the quoins being formed with
the serrations or pitched holes for the pin to enter at any particular position and
the side-sticks having suitable holes or serrations for the other member of the key
to enter.
We construct our improved quoins and side sticks from metal, wood or other
suitable material, and we make the manipulating or actuating key of a suitable
form convenient for providing the necessary adjustment upon the wedge surfaces,
preferably providing it with steel pins for easy replacement in the event of wear or
breakage, or the pins may be cast or formed solid with the key.

and Machine Beds.
We, EDWARD THOMAS CLEATHERO, of 16 Tollington Place, London, N. and
EDMUND WILLIAM HORNSEY WALKER, of 31 Bouverie Street, London, E.C.,
Engineers, 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 statemeni :-
This invention relates to an improved method of constructing quoins and side
sticks for use in printing chases, and machine beds, the object of the invention
being to produce a simple and safe adjustable quoin and one which will have great
strength of resistance when being driven up or tightened within the chase.
In the accompanying sheet of explanatory drawings-
Figure 1 is a front elevation and
Figure 2 is a plan showing our improved quoins and side stick.
Figures 3 and 4 are detail elevations showing smaller quoins, and
Figure 5 is an elevation of the operating key or spanner.
In carrying our invention into effect in one convenient manner, we make our
quoins preferably in pairs in the form of two oppositely-shaped wedges A B
arranged so that the two inclined surfaces meeting, form or produce two parallel
surfaces a bon the outer faces. We cause one wedge or quoin A to slide by the
side of the other B so as to expand or contract upon the forme within the chase by
providing a number of recesses A2 alternating with serrations or rack-like teeth A¹
within the upper surface of the inclined face, and a corresponding number of
recesses B and serrations B in the opposite face. We employ an improved key
or fork C for manipulating the two sliding wedges, arranged in such a manner that
one key or pin D of the fork enters within one recess A² on one of the wedges,
while the other pin or limb D' of the key enters a recess B' upon the other
inclined face. Upon the key being turned, one wedge is driven over the other,
and a closer contact is made between the chase and the forme; to release the
wedges or quoins the key or handle is turned in the opposite direction.
We prefer to form our quoins with the serrations on each side so that the key
can be employed to move the wedges in either direction, one wedge being thrust
in one direction, and the other being thrust forward in the opposite direction and
sliding one upon the other.
Instead of making the serrations or recesses with open mouths or with entrances
from the front or the face of the inclined part of the wedge, we sometimes make a
number of holes instead, the holes being formed suitable for the leg or pio D of
the key to enter, one pin or one leg of the key entering in one hole upon one of
the wedges while the other enters upon the companion side-hole on the other
wedge.
When making our improved side-sticks or providing for great lengths within the
chase we may use short quoins, for locking purposes, the quoius being formed
with the serrations or pitched holes for the pin to enter at any particular position
and the side-sticks having suitable holes or serrations for the other member of the
key to enter.
We construct our improved quoins and: side sticks from metal, wood or other
suitable material, and we make the manipulating or actuating key of a suitable
form convenient for providing the necessary adjustment upon the wedge surfaces,
preferably providing it with steel pins for easy replacement in the event of wear or
breakage, or the pins may be cast or made solid with the key.

page_text: 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;-
1. The improvements in quoins and side sticks for use in printing chases and
machine beds substantially as and for the purposes herein before described and as
illustrated in the accompanying drawings.
2. The construction and arrangement of a pair of oppositely tapered wedges
forming the outer faces parallel, and having holes or serrations by means of which
when a suitably formed key is employed one can be made to slide or move over the
other substantially as and for the purposes hereinbefore described.
3. The improved key or manipulating lever for use in connection with printing
quoins and sticks substantially as herein before described and as illustrated in the
accompanying drawings.
