Paper to Printing, Embossing, and other Machines.
I JOHN JAMES ALLEN of 12 Saint James's Street, Halifax in the County of York,
Engineer do hereby declare the nature of this invention to be as follows:-
This invention consists of a platform upon which the sheets are placed to be operated
upon. A descending bar (preferably of angular or semi-angular shape) a portion of
the underside of which is covered with rubber or other suitable material, is placed
immediately in front of the sheets; or a series of fingers may be employed for the
same purpose. A series of drums, in some of which blocks of india rubber or other
suitable material are inserted are mounted on a shaft which extends over the width
of the paper the plain drums being for the purpose of keeping the paper under
control, whilst the drums in which the india rubber blocks are inserted are for the
purpose of separating the sheets in the following manner.
One or more of the drums
aforesaid in which the india rubber blocks are inserted are attached loosely on the
above shaft driven by a separate band from the rest these moving in one direction
facilitate the separation of the top sheet only from underneath the fingers in front
of the sheets, which immediately stretches itself over the fingers whilst the plain surface
drums operate upon the top sheet for the purpose of keeping it under control-the
remaining drums in which the india rubber blocks are inserted revolving in an
opposite direction propel the sheets forward to the grippers of the machine. Side
guides are provided for the purpose of keeping the sheets in position.

Fig. 2 is a front elevation in section of Fig. 1, through the line Y. Z.
Fig. 3 is a front elevation of Fig. 1.
Fig. 4 is an elevation of lever and weight.
In a suitable frame A, I employ two tables B and (pivotted and connected by con-
neeting bars (; the table B is for the purpose of holding the bulk of the weight of
paper and the table is kept perfectly horizontal or level, I form a recess C² in table C
across which is placed an elastic or other yielding material (³, preferably indiarubber,
so-as: to secure an even controlling pressure upon the sheets from first to last.
Above the table is placed a finger disc D, for propelling the paper forward to two
gripper rollers E F, fixed in the frame A.
At each side of the finger disc D, is a second finger disc G, loose upon the
'shaft D¹, and operated by reversible cranks G¹, upon a second shaft G³, and connecting
links Gs, crank G, to the shaft D'; these finger discs G move first in an opposite
direction to the finger disc D, and by connecting links G from the inner cranks G',
to the loose discs G, draw back and separate the top sheet from the rest, then the
discs G are reversed, and with the disc D propel the sheet forwards.
.
Each of these finger discs is provided with an indiarubber or other elastic projection,
or finger S upon their peripheries for separating, registering, and feeding or propelling
the sheets forward to the gripper rollers; the aforesaid discs are made sufficiently large
to take the largest sheets of paper used on the printing and other machines, they are
required to feed, thereby taking all the smaller sizes.
The table is mounted upon a spindle H which is attached to it by means of a
bracket J, and is held in contact with the discs by means of the spring K, lever T,
and adjustable weight T for increasing or diminishing the pressure or friction as
desired, at the same time the table is kept perfectly level.
Fingers L M are fixed th'a suitable slide L' (adjustable by means of the screw L'
and bracket L³) for holding the sheets of paper to be fed to the gripper rollers, in the
proper position upon the table C; the finger L is pointed so as to penetrate and hold
the sheets, whilst the finger M controlls the table and forms a guide for each sheet to
pass over to the gripper rollers.

page_text: Upon the sheets being placed in position upon the tables B and C, and beneath
the fingers L and M, the discs G are operated in one direction by means of the cranks,
connecting links, and gear wheel P, so drawing back and separating the top sheet
from the rest under the finger L, as soon as that is accomplished, the aforesaid discs G
are reversed, and with finger discs D grip the sheet of paper and propel it forward
over the finger M. to the gripper rollers E, F, which in turn pass it forwards to the
grippers of the printing, embossing, or other machines; the aforesaid motion being
repeated until the very last sheet of paper upon the tables has been removed, or
operated upon.
The discs are operated by a gear wheel P and handle P¹ gearing with another
wheel R operating the gripper rollers.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The separating and feeding of sheets of paper to printing, embossing and
other machines, by means of reversible and registering discs for the purposes set
forth.
2. The combination of a suitable double feed table B and C, finger discs D, G, G,
moveable or reversible cranks G³, G', and connecting links G³, G, fingers L, M,
and gripper rollers E, F, operated as and for the purposes shown and described.
3. The combination of the double feed table B and C, finger discs D and G G,
fingers LM, and gripper rollers E F, as and for the purposes, substantially as shown
and described.
4. The combination of the double feed table B and C, finger discs D and G G, and
fingers I. M, substantially as shown and described.
5. The combination of the finger discs D, and G G, reversible crank G¹, with
connecting links G, and the double feed table B and C, substantially as shown and
described.
6. The combination of the finger discs D, and G G, reversible cranks G¹, with con-
necting links G and fingers L. M substantially as shown and described.
7. The combination of the fingers L and M, and double feed table B and C, as and
for the purposes shown and described.
8. The finger disc D, and the gripper rollers E, F for the purposes as shown and
described.
9. The table C having recess C, and elastic or other similar covering C³, as and for
the purposes described.
10. The general construction and arrangement of apparatus for the purposes
substantially as shown and described.
