I JAMES GILBERT CUMMING of 51 Lothian Road, Edinburgh in the County of
Mid-Lothian, North Britain, Machinist, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object the separating of single sheets of paper from a
pile consecutively with certainty and rapidity and the feeding or moving of the
single sheets into or through Printing, Ruling, Calendering, Folding and similar
machines.
The first part of the invention consists in employing in combination an Electric
magnet, contact breakers, and battery, arranged so that a sheet of paper in going
through a contact breaker, breaks the electric circuit and controls the moving forward
of sheets of paper from a pile.
Second In a guard made of thin cloth or paper, attached by a spring to the
rear end of the machine and placed on the top part of a pile of paper, which is
laid on a vertically movable horizontal table, which by means of levers, keeps the
top sheet of the pile on the level with the lower part of a scraper.
Third In employing in combination a scraper made of a thin piece of wood or
other suitable material, fixed to a horizontally movable rod above the guard and
controlled by the electro magnet, contact breakers and battery, to lower on the guard
when moving forward and to rise off the guard when returning, thus allowing the
guard to return to its position. The contact breakers control the scraper, so that
the sheets of paper from the pile are either moved forwards or stopped at any time or
part of the machine.
The rod to which the magnet and scraper are attached is actuated by a crank fixed
to a driving shaft on the side of the machine.
Fourth In a horizontally reciprocating har with several automatic grippers and
attached by rods to an oscillating shaft.
The second part of the invention consists
First. In a guard in combination with an electro magnet, contact breakers battery,
and scraper-The contact breakers control the guard, so that the sheets of paper

page_text: from the pile are either moved forward or stopped at any time or part of the
machine.
Second. In the employing of a scraper attached to a horizontally movable rod
moving forwards and backwards and actuated by a crank fixed to a driving shaft
on the side of the machine-The scraper is lowered on the guard when moving
forward and raised off the guard when returning, the raising and lowering of the
scraper is done by two cams on the side of the machine.
The third part of the invention consists
First In a gripper in combination with an Electro magnet, contact breakers,
battery, and scraper to control the moving forward of the sheets of paper from the
pile, constructed so that the gripper when released by the magnet rests on the rear
end of the sheet of paper, which is under the first one, thereby allowing the first sheet
to be taken away without moving the rest.

JAMES GILBERT CUMMING lately residing at 51 Lothian Road, now at 7 Union
Street, Edinburgh in the County of Midlothian North Britain Machinist 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 has for its object the separating of single sheets of paper from a
pile consecutively, with rapidity, and the feeding or moving of the single sheets into
or through Printing, Ruling, Calendering, Folding, and similar machines.
The first part of this Invention consists―
First. In the employing in combination of an Electro magnet, contact breakers
and battery arranged so that a sheet of paper in going through a contact breaker
breaks the Electric circuit and controls the moving forward of sheets of paper from
a pile, as will be hereinafter explained.
Second. In a Guard, made of thin cloth or paper, attached by a spring to the rear
end of the machine, and placed on the top part of the pile of paper which is laid on
a vertically movable horizontal table, which by means of levers, keeps the top sheet
of the pile on the level with the lower part of a scraper, as will be hereinafter
explained.
Third. In the employing in combination a scraper made of a thin piece of wood or
other suitable material, fixed to a horizontally movable rod above the Guard, and
controlled by the Electro Magnet, contact breakers and battery to lower on the Guard
when moving forwards, and to rise off the Guard when returning, thus allowing the
Guard to return to its position.
The contact breakers' control the scraper so that the sheets of paper from the pile
are either moved forward or stopped at any time or part of the machine.
The rod to which the Magnet and Scraper are attached is actuated by a crank
fixed to a driving shaft on the side of the machine, as will be hereinafter
explained.
Fourth. In a horizontally reciprocating bar with several automatic grippers and
attached by rods to an oscillating shaft, as will be hereinafter explained.
In the Drawings Figure 1 is a side elevation, figure 2 is an end elevation and
figure 3 is a plan of figures 1 and 2. Figures 4. 5. 6. 7. 8. 9. 10. and 11, are detail
views of this invention.
The frame of the machine consists of two sides A, A¹, connected together by cross
bolts or stays, B is a vertically movable horizontal table on which the pile of paper C
is placed, this table rests on four levers B', B1, B1, B¹ as shewn in fig. 1 and 2, and
raised by means of a lever with a movable balance weight B2, so as to keep the top
sheet of the pile up against the point of the Scraper D (fig. 1).
A wire from the negative pole C of the battery J is connected to the magnet E, and
a wire from the positive pole of the battery, connected to the metal plate f, which
extends across the machine, and on which rests the contact breaker F, a wire is
connected from the contact breaker F, to the lower part F, of the contact breaker Ft,
and from the contact breaker F¹ to the magnet E, (as shewn in fig. 1).
The Scraper D is carried on centres d, and controlled by the magnet E in'
combination with the contact breakers F, and F¹, and a battery J. The Scraper D

page_text: and magnet E are moved backwards and forwards by means of rods K, connected
to a crank K, and fixed to a driving shaft K2 on side of machine, (as shewn in
fig. 1).
The Scraper D moves over the surface of the Guard H, which lies on the surface of
the pile of paper G.
The contact breaker F (which is in combination with a contact breaker F¹, a
magnet E, and Electric battery J) when in circuit, communicates the current to the
lower part F, of the contact breaker F¹, and by means of the, contact breaker F',
moving against the cam G, it is brought in contact with the lower part F³, and the
circuit is completed with the magnet E, only when the magnet E and Scraper D are
moving forwards. The contact breaker F¹ breaking the circuit before returning by
moving against the cam G¹, thus loosing connection with the lower part F³.
The Scraper D to which is fixed an armature E', is drawn up against the magnet E,
and by turning on the centers d, the end or point of the Scraper D is pressed down
on the surface of the Guard H-By the friction of the Scraper D on the Guard H,
the single sheets of the pile of paper C.are thus moved gradually forward to the
contact breaker F.
When the front edge of the first sheet of paper from the pile C, moves through
between the contact breaker F, and the metal plate f, the electric circuit is broken,
and the magnet E releases the scraper D, which rises off the Guard H--The scraper
continuing to move backwards and forwards without touching-the Guard H, and the
pile of paper remains stationery.
The Grippers L, which are fixed to a cross bar L' are moved backwards and
forwards by means of rods M connected to a crank M¹ fixed to a shaft M2 on the side
of machine (as shewn in Fig. 1).
The cross bar L₁ in moving backwards towards the contact breaker F, moves
against a lever P (as shewn in fig. 1) which is connected by a rod P₁, to an arm
attached to a spindle P' which turns on centres, and on which the contact breaker F
is fixed-The cross bar L' in moving the lever P, causes the spindle P³, to turn on its
centres which moves the contact breaker F, down under the level of the sheet of paper
(as shewn in fig. 1).
The Grippers L after gripping a sheet, which is done by means of a cam 1 opening
the grippers L and allowing the grippers L to close ou the front edge of the first sheet
of paper.
The sheet is then moved forwards and by means of a cam 11 opening the grippers L,
the sheet of paper is dropped on to tapes R, which runs it into the Printing, or other
machine.
When the sheet of paper moves over the contact breaker F, the cross bar L' releases
the lever P, which moves the contact breaker F up under the sheet of paper into
circuit again, thereby sending the electric current to the magnet E which acts on the
Scraper D and again moves the sheets of paper in the pile C forward to the contact
breaker F which waits on the Grippers L to take away the sheet and so on till the
pile of paper C is finished.
said
Having now particularly described and ascertained the nature of my
Invention, and in what manner the same is to be performed, I declare that what
I claim is.
First. The electric contact breakers F and F¹ with cams G and G' combined with
the magnet E, Scraper D and battery J, substantially as described.
Second. The Guard H, substantially as described.
