We THOMAS WHITE SMITH of the firm of H. W. Caslon and Company of
22 Chiswell Street in the County of Middlesex Type Founder and CHARLES
JAMES GAMBLEN of 7 Monteith Road Old Ford North Bow in the County of
Middlesex Printers' Rulo Maker do hereby declare the nature of our invention
for IMPROVEMENTS IN APPARATUS FOR SUPPORTING AND SECURING STEREOTYPE
AND OTHER PLATES IN POSITION FOR PRINTING THEREFROM to be as follows:-
In order to printing from stereotype and other plates being effected it is usual
to mount these plates on blocks of a height adapted to support those plates level
with the height of ordinary type and various plans have been adopted for securing
such plates in their desired position on the blocks, and in proper position for
being printed from but various inconveniences attend all the arrangements which
are in use, so far as we are acquainted with them.
The object of our invention is to provide means for supporting and securing
auch plates which shall be, cheaper in construction and in use, as well as better
adapted to their purpose.
In carrying out our invention we form the blocks or supports of metal hollow
on the under side and with bevelled edges to the walls resting on the bed of the
machine or other surface during use, and these blocks we arrange beneath the
plates according to size packing them with leads and rules to the figure required
and then around the edges of these blocks and so as to clasp the bevelled lower
edges of the walls thereof and the edges of the stereotype or other plate to be
secured we place catches or pieces of brass or other suitable metal, having straight
sides and bevelled inclined edges corresponding with the bevelled edges of the
blocks and adapted to overlap the thin edges of the plates and to hold the plate
down to the blocks.
To prevent edge clips or catches such as described from shifting endwise thin
pieces of metal of the proper length and size may be inserted between the catches
and against the blocks.
Should the plate to be held in position happen to be out of the square or out of
truth, such defect can be justified or remedied by padding or filling up the space
between the catch and the supporting abutment by card or leads.

page_text: The parts having been adjusted as described the whole will be secured in
the chase or frame by wedging or otherwise in manner as is well understood.
These catches may be readily produced by pressure from divided portions of
strips of metal of the proper widths and thickness.
Amongst other advantages attendant on the use of this invention are the
thinness and lightness of the catches, their facility of application at various parts
of a plate so as not to press or bear always upon one particular point and their
removeability to other points of hold at will should the plato break away also the
lessened liability of such catches to project sufficiently over the edges of plates to
print” or deface the sheet printed from the plate held by them.

COMPLETE SPECIFICATION,
We THOMAS WHITE SMITH of the firm of H. W. Caslon & Company of
22 Chiswell Street in the County of Middlesex Letter Founder and CHARLES
JAMES GAMBLEN of 7 Monteith Road Old Ford, North Bow in the County of
Middlesex Printers' Rule Maker do hereby declare the nature of our invention
for IMPROVEMENTS IN APPARATUS FOR SUPPORTING AND SECURING STEREOTYPE
AND OTHER PLATES IN POSITION FOR PRINTING THEREFROM, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
These improvements relate to means for retaining stereotype and other plates
upon blocks during printing therefrom.
In order to printing from stereotype and other plates being effected it is usual
to mount these plates on blocks of a height adapted to support those plates level
with the height of ordinary type and various plans have been adopted for securing
such plates in their desired position on the blocks, and in proper position for
being printed from but various inconveniences attend all the arrangements which
are in use, so far as we are acquainted with them.
The object of our invention is to provide means for supporting and securing
such plates which shall be, cheaper in construction and in use, as well as better
adapted to their purpose.
In carrying out our invention as illustrated by the accompanying drawings in
which Fig. 1 is a side view of a block a with a stereotyped plate b resting on it
held by the catches or clips c We form these blocks or supports of metal a
hollow on the underside a¹ and with bevelled edges a² to the walls resting on the
bed of the machine or other surface during use, and series of these blocks a we
arrange beneath the stereotype or other plates according to size packing them with
leads and rules to the figure required and then around the edges of these blocks
and so as to clasp the bevelled lower edges a¹ of the walls thereof and the edges
of the stereotype or other plate b to be secured we place catches or pieces of brass
or other suitable metal c having straight sides c¹ and bevelled inclined edges c²
corresponding with the bevelled edges a² of the blocks and adapted to overlap
the thin edges of the stereotype or other plates b and to hold that plate b down to
the blocks a
To prevent edge clips or catches such as described from shifting endwise thin
pieces of metal of the proper length and size may be inserted between the catches
and against the blocks.
Should the plate to be held in position happen to be out of the square or out of
truth, such defect can be justified or remedied by padding or filling up the space
between the catch and the supporting abutment by card or leads.
The parts having been adjusted as described the whole will be secured in
the chase or frame by wedging or otherwise in manner as is well understood.
These catches may be readily produced by pressure from divided portions of
strips of metal of the proper widths and thickness,

page_text: Amongst other advantages attendant on the use of this invention are the
thinness and lightness of the catches, their facility of application at various parts
of a plate so as not to press or bear always upon one particular point and their
removability to other points of hold at will should the plate break away also the
lessened liability of such catches to project sufficiently above the edges of plates to
'print" or deface the sheet printed from the plate held by them.
"
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The construction or arrangement of parts for supporting and securing |
stereotype and other plates in position for printing therefrom as set forth.
Dated this 8th day of June 1885.
