PROVISIONAL SPECIFICATION.
Improved Means for Holding or Permitting Substitution of Blocks
or Plates in Boards for Printing Purposes.
I, WILLIAM JOHN CUMMINS, of Eagle Printing Works, Bishop Auckland in
the County of Durham, Printer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improved means for holding or permitting substitution
of blocks or plates in boards for printing purposes.
Instead of inserting the block plate electro or the like in the board or as part of
the principal block or plate on the board from the front side and then securing it
there by nailing packing or otherwise I arrange in the board frame on the face of
which there may be any number of blocks each requiring means for holding or
adjusting certain parts of the matter to be printed therewith and at the rear side
thereof adjustable or movable parts or wood or other strips so that after removing
one or more such parts as the case may be access can be had to the backs of the
blocks or plates on the board and into the required openings or spaces therein
I then drop the plates or blocks containing the required matter to be printed with
the principal blocks or plates and thereafter I replace the wood or other strip or
movable piece which presses against and keeps the main plates or parts of same in
the required positions.
Button clamp spring or other equivalent fastenings serve to unfasten or fasten
the adjustable strips or pieces above alluded to.
The separate or minor parts can conveniently half-lap joint onto the main
plates or blocks and be there retained or removed with facility as above
foreshadowed.
Dated this 1st day of April 1896.

Improved Means for Holding or Permitting Substitution of Blocks
or Plates in Boards for Printing Purposes.
I, WILLIAM JOHN CUMMINS of Eagle Printing Works, Bishop Auckland in
the County of Durham Printer, 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 improved means for holding or permitting substitution
of blocks or plates in boards for printing purposes.
Instead of inserting the block plate electro or the like in the board or as part of
the principal block or plate on the board and then securing it there by means of
nailing packing wedging and the like clumsy processes as has hitherto been the
case I arrange in the board frame on the face of which there may be any number
of blocks each requiring means for holding or adjusting certain parts of the
matter to be printed therewith and at the rear side thereof adjustable or movable

case may be access can be had to the backs of the blocks or plates on the board
and into the required openings or spaces therein I then drop the plates or blocks
containing the required matter to be printed with the principal blocks or plates
and thereafter I replace the wood or other strip or movable piece which presses
against and keeps the main plates or parts of same in the required positions.
Button clamp spring or other equivalent fastenings serve to unfasten or fasten
the adjustable strips or pieces above alluded to.
The separate or minor parts can conveniently half-lap joint onto the main
plates or blocks and be there retained or removed with facility as above
foreshadowed.
I will fully describe my invention with reference to the accompanying drawings
in which Figures 1 and 2 show back and front elevations of part of a board fitted
with blocks or plates Figures 3 and 4 showing sectional plan and vertical sectional
views on respectively lines A B and C D in Figures 1 and 2 and in the following
description like marks of reference designate like parts.
Referring to the drawings to the front of the board 7 are attached in any
convenient manner the blocks or plates 8 on which may be formed or inscribed
the required matter to be printed. In each of such blocks plates electros or the
like as the case may be there is an opening into which is intended to be inserted
from the back and through a suitable slot 11 cut in the board 7 a part of a block
plate or electro (such as 9) in such a manner that such part can be readily removed
or interchanged. I prefer to half-lap the part 9 onto the part 8 as shown by a
"beard" as at 10 so that the front part of the part 9 is in allignment with and in
its correct position with regard to the front of the part 8.
Having thus dropped into their required positions as many of the parts or
electros 9 as there are parts or plates 8 or as may be required I replace the wood
or other strip 12 in the slot or opening 11 so that it presses against the rear faces
of the parts 9 and holds them securely in position the strip 12 itself being made
secure in or as part of the board 7 by any simple means for example by the
buttons 13.
The whole board is now ready for printing from and to change the parts 9 it
is only necessary to remove the several strips 12 which at once gives access to
them when if desired other parts 9 can be substituted and the process continued
as described.
One strip 12 can thus hold a series of adjustable parts such as 9 and the
simplicity of the arrangement is found to give in practice very economical
results.
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. The improved means for holding or permitting substitution of blocks or
plates in boards for printing purposes consisting in the provision of openings in
the boards for giving access to the required interchangeable parts and of
adjustable strips for securely holding such parts in the required positions the
several parts being arranged disposed or adapted for use substantially as and for
the purposes herein set forth.
2. The improved means for holding or permitting substitution of blocks or
plates in boards for printing purposes substantially as herein described and
illustrated in the accompanying drawings.
