PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Separating and Feeding Sheets of
Paper to Printing, Ruling, Embossing, and other Machines.
I JOHN JAMES ALLEN of the Allen Machine Company Limited, 3 George Street,
Halifax in the County of York, Engineer, do hereby declare the nature of this Inven-
tion to be as follows:
The object of this invention is to facilitate the separation of sheets of paper from
a pile, register the same to the grippers of printing machines, and for preventing
setting or smearing of such sheets during the process of feeding.
For this purpose I employ a movable table balanced by springs or weights, upon
which I place the sheets; also an arrangement of adjustable discs or fingers above
the table in which indiarubber or other flexible material is inserted for manipulating
the sheets.
The discs or fingers are mounted upon a shaft driven by a chain and chain-wheels
from the printing machine and are adjustable laterally to the margins of the sheets.
For the aforesaid purpose I employ a bracket or series of fingers in front of the
table, for holding the sheets in position; for controlling the sheets at the back, and
preventing the discs from taking more than one sheet at a time, I employ adjustable
fingers in which are inserted needle points, or sharpened instruments, or india rubber,
mounted on a bracket or brackets, immediately behind the table.
For securing the accurate delivery of the sheets to the grippers, I employ an
automatic arm which is fixed to the side of the printing machine, and is operated
by a connecting rod and cam or eccentric from the main or other shaft.
The action is as follows:-
When the ream or pile of sheets has been placed in position upon the table, the
two discs propelled by the chain wheels operates upon the top sheet and draw it
from under the adjustable fingers at the back, after which it is passed forward by
means of the aforesaid discs, through two gripper rollers in front of the feeding.
apparatus, on to endless bands when it is placed in position by the automatic arm, to
be taken hold of by the grippers of the printing or other machine.

Improvements in Apparatus for Separating and Feeding Sheets of
Paper to Printing, Ruling, Embossing, and other Machines.
I JOHN JAMES ALLEN of the firm of Allen Machine Company Limited 3 George
Street, Halifax in the county of York, 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 :-
The object of this invention is to facilitate the separation of sheets of paper from a
pile, register the same to the grippers of Printing and other machines, and for
preventing setting or smearing of such sheets during the process of feeding.

page_text: I employ moveable tables C and C¹, balanced by weights or springs D upon the
studs E, on the table CI place the sheets F, also an arrangement of adjustable discs
or fingers G upon shaft H, above the table Cin the said "discs indiarubber or other
flexible material J is inserted for manipulating the sheets.
The discs or fingers upon the shaft are driven by its chain K and chain wheel K'
from the chain wheel attached to the printing machine, and are adjustable upon their
shaft laterally preferably by the margins of the sheets.
For facilitating the placing of the pile of sheets in position upon the table CI fix
a rod W across the back of the table, upon this rod are two adjustable fingers W
projecting up against the end of the table and which are immediately thrown back
after the sheets have been adjusted, and before the machine is set in motion.
I also employ adjustable brackets or lays L and a series of fingers or discs M
(preferably of indiarubber) (in front of the table C) fixed upon a rod M¹ sliding
vertically within the brackets M² such brackets being adjusted upon a slide M³ for
controlling the ends of the sheets.
For controlling the sheets at the back and preventing the discs G from taking more
than one sheet at a time, I use hinged or pivotted fingers N preferably adjustable in
which are inserted needle or knife points P, the said fingers may be worked radially
as shown, or may slide vertically.
For securing the accurate delivery of the sheets to the grippers 0, and putting
the required tension on the sheets, I employ an arm R with runner R', which is
fixed upon a cross shaft R2, and is operated by a lever S, and weight S', at one end
of the shaft R².
The gripper rollers O are driven from the shaft H by gear wheels T and T, the
shaft is driven by intermediate gear wheel T3 and pinion T². The gripper rollers O
pass the sheets to the endless bands or aprons X which run upon the pulleys Y
and rollers X¹, within a table Z³ and deliver the sheets to the grippers of the
printing or other machine. In course of delivery the sheets are operated upon by
an automatic feeling arm Z, which derives its motion from a connecting rod Z¹ and
cam Z, upon the main or other shaft, for the purpose of registering the delivery of
the sheets to the grippers; the said feeling arm can be adjusted to suit the various
widths of the paper used.
Having fully described the nature and particulars of the said invention, and
the manner in which the same is carried into effect, I claim.
