PROVISIONAL SPECIFICATION.
An Improved Method of Feeding Paper to Cylinder Printing
Machines, and in Appliances for the Purpose.
I, MARTIN WRIGHT, of The Cyltine Manifold Copying Machine Company,
Highfield Works, Upper Kent Street, Leicester, Manager, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved method of feeding paper to cylinder
printing machines, and in appliances for the purpose, the object being to fit
adjustable stops on a reciprocating table or board capable of moving towards the
cylinder by springs, or their equivalents, and to return by cams for the reception
of fresh sheets of paper in succession.
As an example of my invention, I arrange a reciprocating sliding table on
bearers which can be moved forward rather suddenly by springs to feed the paper,
previously placed upon the table, to the grippers of the cylinder which open in the
usual manner for the purpose of receiving it. The table is returned by cams from
the cylinder axle and held back for enabling an attendant to select and place a
sheet under and against the gauges ready for the next feed.
The table or board slotted or recessed for adjustable gauges to be set at any
desired part by screws according to the size of the sheets to be printed. These
gauges have their overlap points looking forwardly, and the paper as laid on, is
passed a little to the front, and then drawn back under the points and against
them, which in the next forward movement of the table, takes the sheet to the
grippers.
If the sheet is not brought back to bear against the gauges, it will be overtaken
by them, and then be forced forward to the grippers. By this means, the close
application of the attendant's eye and hand to feed the paper to the front stops, so
essential under the present system, is obviated.

COMPLETE SPECIFICATION.
An Improved Method of Feeding Paper to Cylinder Printing
Machinės, and in Appliances for the Purpose.
I MARTIN WRIGHT of The Cyltine Manifold Copying Machine Company,
Highfield Works, Upper Kent Street, Leicester, Manager, 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 an improved method of feeding paper to cylinder
printing machines and in appliances for the purpose the object being to fit
adjustable stops on a reciprocating table or board capable of moving towards the
cylinder by springs cams or their equivalents and to return by cams or springs for
the reception of fresh sheets of paper in succession.
As an example of my invention 1 arrange a reciprocating sliding table on bearers
which can be moved forward rather suddenly by springs or cams to feed the paper
previously placed upon the table to the grippers of the cylinder which open in the

page_text: usual manner for the purpose of receiving it. The table is returned by cams or
springs and held back for enabling an attendant to select and place a sheet under
and against the gauges ready for the next feed.
The table or board is slotted or recessed for adjustable gauges to be set at any
desired part by screws according to the size of the sheets to be printed.
These gauges have their overlap points looking forwardly and the paper as laid
on is passed a little to the front and then drawn back under the points and against
them which in the next forward movement of the table takes the sheet to the
grippers.
If the sheet is not brought back to bear against the gauges it will be overtaken
by them and then be forced forward to the grippers. By this means the close
application of the attendants eye and hand to feed the paper to the front stops, so
essential under the present system, is obviated.
My invention will be understood by reference to the annexed drawings of which
Figure 1 represents a part sectional elevation in which the reciprocating table is
actuated by a spring to feed the paper, the return of the table being effected by
a cam.
Figure 2 is a similar elevation in which the table is moved towards the cylinder
by a cam and returned by a spring.
A is the printing cylinder B the pressure cylinder, C the table and D the spring.
E is the adjustable stop or gauge on the table.
The invention is here shown in connection with a machine patented by me on
the 18th day of November 1891 No. 20064 in which the lever frame F is made to
lift the pressure roller for work during printing.
The cam by my present improvements is actuated by gear G and according
to Figure 1 the cam is formed by a flat edge of a disc H to press directly against
the lever I pivoted at J but according to Figure 2 the cam F is of nose shape on
the disc H and presses against the tail K of the lever I pivoted at L. In both.
cases the table reciprocates in a straight plane but it can be set to move at an
angle or otherwise as desired.
M is the gripper for taking the paper round with the pressure cylinder B for the
printing and for releasing it when the printing is completed.
It will be seen from the shape of the cam that a sufficient pause of time takes
place to enable an attendant to place the paper on the table ready for its movement
to the cylinder.
Having now particularly described the nature of this invention and in what
manner the same is to be performed I declare that what I claim is
The means or appliances hereinbefore described and shown for feeding paper to
cylinder printing machines especially to those machines previously patented by me
as aforesaid or any equivalent machine.
