PROVISIONAL SPECIFICATION.
Improvements in Perforating Machines.
I, ALFRED PARTRIDGE of 5 Cannon Street Manchester in the County of
Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines that are employed for perforating paper,
card-board, and like materials, for the purpose of division.
In the accompanying sheet of drawings Figs. 1 and 2 represent respectively part
front view and part side view of a machine constructed according to this invention;
in these views similar letters refer to similar parts.
I form the shaft a, the lugs b, and the lever d, of cast metal or other suitable
material in one piece.
I place the shaft a parallel with the surface of a table or stand e that may be of
any convenient form and resting on metallic supports or on a bench; I support the
shaft a, by means of brackets or bearings fand g, that are placed near to each end
of said shaft.
I form the bracket fin two parts so that the part f¹ may be removed by
unscrewing the set screw h.
I connect the sliding frame j, which carries the punches k, to the shaft a by the
connecting links 1, which are placed at an angle as shown in Fig. 2.
I connect the end of the lever d to the rod m, which at its lower end is attached
to a treadle n whose fulcrum is at o. The foot rest p, which is attached to said
treadle is kept raised by the spring y when not in work.
The action of the treadle n, is adjusted by the screwed end m¹ of the rod m..
In order to perforate the material by means of the punches k, said material is
placed on the table under plate s, when the operator depresses the front end of the
treadle by means of the foot rest p, which causes the rod m to pull down the
lever d, thereby causing the centre t to be placed in the same plane as the centres u
and v.
By these means the frame j, with the punches &, is pressed down and the punches
perform their work of perforation; when the foot rest p is released it is raised by
the spring g, and the punches are withdrawn, the plates pressing the material off
the punches in the usual manner.
The rise and fall of the foot rest p is regulated by the slotted bar x that may be
attached to the supports of the table.
The top of the table at one end is open and free to draw the material away after
it has been perforated.
When it is required to take out the shaft a, the part of the bracket is
removed, when said shaft can slide out freely.
Dated this 8th day of September 1892..

Improvements in Perforating Machines.
1, ALFRED PARTRIDGE of 5 Cannon Street, Manchester, in the County of
Lancaster, Engineer, 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 machines that are employed for perforating paper,
card board, and like materials for the purpose of division.
The drawings to which I hereinafter refer are those left with the Provisional
Specification, in which Figs. 1 and 2 represent respectively, part front view and
part side view of a machine constructed according to this invention in these views
similar letters refer to similar parts.
I form the shaft a, the lugs b, and the lever d, of cast metal or other suitable
material in one piece; I place the shaft a parallel with the surface of a table or
stand that may be of any convenient form, and resting on metallic supports or on
a bench I support the shaft a by means of brackets or bearings and g that are
placed near to each end of said shaft.
I form the bracket f in two parts, so that the part f¹ may be removed by
unscrewing the set screw h.
I connect the sliding frame j, which carries the punches k, to the shaft a, by the
connecting links l, which are placed at an angle as shown in Fig. 2.
I connect the end of the lever d to the rod m, which at its lower end is attached
to a treadle n whose fulcrum is at o. The foot rest p, which is attached to said
treadle is kept raised by the spring when not in work.
The action of the treadle n, is adjusted by the screwed end m³ of the rod m.
In order to perforate the material by means of the punches k, said material is
placed on the table under the plate s, when the operator depresses the front end of
the treadlen by means of the foot rest p which causes the rod m to pull down the
lever d, thereby causing the centre t to be placed in the same plane as the centres u
and v.
By these means the frame j with the punches & is pressed down and the punches
perform their work of perforation; when the foot rest p is released it is raised by
the spring and the punches are withdrawn, the plates pressing the material off
the punches in the usual manner.
The rise and fall of the foot rest p is regulated by the slotted bar that may be
attached to the supports of the table.
The top of the table at one end is open and free to allow any size of sheet to be
perforated without folding.
When it is required to take out the shaft a, the part f¹ of the bracket fis
removed, when said shaft can slide out freely.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1st. In a perforating machine that is employed for perforating paper, card board,
and like materials the combination of a longitudinal shaft such as a with links
such as that are moved by the action of said shaft from an angular position to a
position at right angles to the shaft, for the purpose and in the manner substantially
as herein before described.
2nd. A perforating machine that is employed for perforating paper, card board,
and like materials, and operated by a treadle, constructed with the top of the table
open at one end, in the manner and for the purpose substantially as herein before
described.

page_text: 3rd. The combination of parts forming a perforating machine that may be
employed for perforating paper, card board and like material, constructed in the
manner substantially as herein before described.
