PROVISIONAL SPECIFICATION.
Improvements in Paper Perforating Machines.
We, THOMAS CHARLES THOMPSON and SYDNEY THOMPSON both of The
Albion Mill, Trumpet Street, Gaythorn, Manchester, Printers' Engineers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to paper perforating machines and its objects are to
provide means whereby sheets of paper of any width may be perforated at any
part and also to provide means for readily removing the pins or punches or any
required group or number of pins or punches from the sliding beam.
In machines as usually constructed the standards or brackets for carrying the
sliding beam are in line with the dies and thus limit the width of the sheet of
paper which may be placed under the punches. In carrying this invention into
effect one or both of the brackets or standards is or are placed behind the line
of dies so that paper of any width may be placed under the punches in any lateral
position. Between the standard or standards and the bed of the machine a gap is left
into which the front edge of the paper may fall. The releasing plate through
which the punches pass is attached to the standards by screws or other suitable
devices.
The punches or pins are formed or secured in the usual manner upon a plate or
plates which is or are attached to the sliding beam with the interposition of
suitable packing pieces which may be firmly secured in place. These packing
pieces are of such a depth that when they are removed the plates carrying the
punches may be raised until the punches are clear of the releasing plate, and then
be readily removed from the sliding beam. Their removal is thus effected without
removing or altering the position of the beam. It is preferred to form the line of
punches in sections, each section being provided with its own packing piece so that
it may be removed without reference to the others.

Agents for the Applicants.
We, THOMAS CHARLES THOMPSON and SYDNEY THOMPSON both of The
Albion Mill, Trumpet Street, Gaythorn, Manchester, in the County of Lancaster,
Printers' 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 statement :—
This invention relates to paper perforating machines and its objects are to
provide means whereby sheets of paper of any width may be perforated in any
part, and also to provide means for readily removing the pins or punches or any
required group of pins or punches from the sliding beam.
In machines as usually constructed the standards or brackets for carrying the
sliding beam are in line with the punches or dies and thus limit the width of the

page_text: sheet of paper which may be placed under the punches. In carrying this invention
into effect one or both of the brackets or standards is or are placed behind the line
of dies so that paper of any width may be placed in any lateral position under the
punches. Between the standard or standards and the bed of the machine is left a
gap into which the front edge of the paper may fall. The releasing plate through
which the punches pass is attached to the standards by screws or other suitable
devices.
In order that our invention may be more readily, understood we have hereto
appended a sheet of drawings to which we make reference hereinafter.
Figure 1 illustrates the machine in end elevation.
Figure 2 illustrates it in front elevation.
A is the frame of the machine provided with table B carrying the dies C.
The brackets or standards D of the machine instead of rising from the table in a
line with the dies or punches, occupy a position to the rear so as to leave a gap
between them and the table of the machine as illustrated by Figure 1. These
brackets carry the sliding heam E which is operated in the usual or any suitable
manner from the shaft F. Fixed to the bottom of the sliding beam are the
punches or pins or needles G which pass through the releasing plate H.
In the arrangement shewn the paper which is to be perforated can be moved to
any extent laterally as it is not limited by the: standards or brackets and any
width of paper may be placed in the machine. Both brackets are illustrated as
being placed behind the line of punches but if desired only one may be so placed.
The front edge of the paper falls into the gap between the bracket or brackets.and
the table.
In order that the punches or needles G may be more readily removed from the
sliding beam of the machine I prefer to form them upon or secure them to plates
or blocks J which are attached laterally to the lower part of the sliding beam.
Above the blocks and between them and the body of the beam are interposed
packing pieces K which are similarly secured to the side of the lower part of the
beam. If it becomes necessary or desirable to remove the punches or any group
of them from the machine then the packing pieces or any required packing piece
is removed and the needles or the required group of needles, after being released
from the beam may be raised until they are free of the releasing plate and then be
bodily removed.
.
In the drawings we have shewn the needles or punches subdivided into three
groups but we may use any desired or suitable subdivision, or all the needles across
the machine may be attached to one and the same plate or block. As many
packing pieces are preferably employed as there are groups of needles."
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. A paper perforating machine in which the sliding beam bracket or brackets
is or are placed or arranged behind the line of dies, substantially as and for
the
hereinbefore described and as illustrated by the accompanying
purpose
drawings.
2. In a paper perforating machine the combination and arrangement with the
punches and the sliding beam of an interposed packing piece or packing pieces,
substantially as and for the purpose herein before described and as illustrated by
the accompanying drawings.
