PROVISIONAL SPECIFICATION.
Improvements in or connected with Frames or Chases for Blocks
and Type.
We, LAUTER SYDNEY BRACHER, of Waterloo Road, Stockport, in the County
of Chester, Manufacturer, and WILLIAM WELLS COLLYER, of Shaw Heath,
Stockport, aforosaid,. Manager, do hereby declare the nature of this invention
to bo as follows:-
This invention is for an improved method of securing type, blocks or similar
printing tools within the frame or chase of a printing machine and is more especially
adapted for use in a frame where the space is limited or where it is necessary to
fill the space within the frame with type or the like thereby leaving no room to be
occupied by any of the locking devices at present in use for the purpose.
In carrying out the invention we use a frame or chase of the ordinary shape
with this difference viz. :-one or more of the inner faces of the frame instead of
being made vertical or more properly at an angle of 90 degrees to the plane of the
frame is cut back at the bottom of the frame so as to present a surface inclined
about 10 degrees from the vertical or about 80 degrees from the plane of the
frame thereby making the space in the frame slightly larger at the bottom than at
the top.
To each of these inclined surfaces we fit a wedge shaped plate whose edges are
parallel but whose sides are inclined to each other at an angle of about 10'degrees
and it will be seen that when this wedge-shaped plate is applied to the inclined
inner face of the frame with its thicker edge at the bottom of the frame the side
of the wedge which is presented to the opposite inner face of the frame is at an
angle of 90 degrees to the plane of the frame and in the proper position to bear
against the bodies of the type or blocks within the frame.
The whole of the space at the top or face of the frame is available for type or
the like the space occupied by the wedge although enclosed within the frame being
outside of such space as may be occupied by type or the like thereby allowing
type to be set close to the frame at the face.
The peculiar shape of the frame renders it difficult for the type or other contents
of the frame to fall outwards in the direction of the face but the contents are easily
unlocked. if moved in-the opposite direction.
In practice we find that it is desirable to incline two adjacent inner faces as
described leaving the other two sides vertical but this arrangement may be varied.
The method of applying the invention is as follows:-The frame is slightly
raised from the imposing table being held in this position by parallel slips
placed under the edges of the frame but not allowed to come over the type space
in the frame.
The wedge or wedges are placed in their respective positions, and the type rule
or other material is filled closely into the frame being allowed to project a little
below the frame and resting on the imposing plate. The slips supporting the
frame are then withdrawn and the frame is pressed down on to the imposing plate
thereby forcing the wedges upwards into the frame and laterally against the type
locking it firmly into place.

We construct the frame or chase A with one or more preferably two of the inner
sides instead of being vertical or more properly at an angle of 90 degrees to the
plane of the face a of the frame is cut back at the bottom of the frame so as to
present a side a¹ inclined about 10 degrees from the vertical or about 80 degrees
from the plane of the frame thereby making the space C in the frame slightly
larger at the bottom than at the top.
To each of these inclined sides we fit a wedge shaped plate or strip B whose
edges are parallel but whose sides are inclined to each other at an angle of
about 10 degrees and it will be seen that when this wedge-shaped plate B is applied
to the inclined inner side a' of the frame with its thicker edge at the bottom of the
frame the side of the wedge which is presented to the opposite inner side of the
frame is at an angle of 90 degrees to the plane of the frame and in the proper
position to bear against the bodies of the type or blocks within the frame.
The whole of the space at the top or face a of the frame is available for type or
the like the space occupied by the wedge although enclosed within the frame
being outside of such space as may he occupied by type or the like thereby allowing
type to be set close to the edge of the face a of the frame.
This peculiar shape of the frame renders it difficult for the type or other contents
of the frame to fall outwards in the direction of the face but the contents are easily
unlocked if moved in the opposite direction.
In practice we find that it is desirable to incline two adjacent inner sides a¹
as described leaving the other two sides vertical but this arrangement may be
varied.
The method of applying the invention is as follows:-The frame A is slightly
raised from the imposing table D being held in this position by parallel slips
placed under the edges of the frame but not allowed to come across the type space C
in the frame.
The wedge or wedges B are placed in their respective positions, and the type,
rule or other material is filled closely into the space C being allowed to project a
little below the frame and resting on the imposing plate D. The slips supporting
the frame are then withdrawn and the frame is pressed down on to the imposing
plate thereby forcing the contents of the frame including the wedges B upwards.

firmly into place.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Frames or chases for printing blocks or type constructed with one or more of
the inner sides inclined at an angle of about 80 degrees to the face in combination
with one or more wedge shaped plates or strips inserted from the back to secure
the type in position substantially as described.
2. A frame or chase for type or printing blocks constructed and arranged in
combination substantially as described and shown.
