PROVISIONAL SPECIFICATION.
Improvements in Striker Motion for Paper Ruling Machines.
I JOHN SHAW, of Westgate, Honley, in the County of York, Ruling Machine
Maker, do hereby declare the nature of this invention to be as follows:-
An invention for changing or altering the speed of the cam shaft in a Striker
Paper-ruling Machine by means of an emery roller driven by the friction of the top
cloth, at the end of the shaft of which said roller is fixed a change wheel driving a
carrier wheel, which said carrier wheel drives the wheel driving the cam shaft. The
nature of the invention is such, that these three wheels are all interchangeable one
for the other, & being thus, the cam shaft can be run six different speeds without
resorting to any fresh change wheels.
COMPLETE SPECIFICATION.
Improvements in Striker Motion for Paper Ruling Machines.
JOHN SHAW Westgate Honley near Huddersfield Ruling Machine Maker 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:
To provide means whereby paper may be so regulated in passing through the
Machine that the successive sheets shall lap or immediately succeed each other in order
to present unruled paper to the pens without having a gap between the sheets and
consequently cause the pens to run over and saturate the cloth or apron with ink, or
make it necessary to elevate the pens to ride over such gaps either of which entails
loss of working time of the Machine.
In order to accomplish this, 1 place a skeleton shaft across the Machine in the usual
position of pen cylinder. On this shaft I have cam head and wing or gate lifter-the
end of the skeleton shaft projecting through the frame of the Machine where marked A
to admit of wheel marked B. In front of this said shaft and parallel with it I place a
cylinder marked C coated with emery or other suitable material.
Through the cylinder is also a shaft parallel with skeleton shaft A the end of
which projects through the frame of the Machine to admit of wheel marked D.
The endless cloth or apron I press against the cylinder with a small roller causing
the cylinder to be rigid and to rotate exactly with the cloth.
I have a radial plate E fixed between the two projecting shafts referred to.
In this radial plate is a slot hole with a pin or stud in, on which is a carrier wheel
marked F.
The three wheels B, D, F, are interchangeable. I gear the three together and by
changing these wheels either one for the other, or other wheels that I have, I vary
the speed of cam head and gate lifter to any speed, causing gate to open at any point,
thus regulating the distance of the sheets passing through the Machine.
In other Ruling Machines the power for this motion is gained from the wheels on
the front feed rollers direct, by means of wheels and cone drums.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The Motive Power to drive the Skeleton shaft which regulates the stop gate. This
s gained by the cylinder covered with emery or other suitable material being driven

page_text: by the Cloth or Belt, such cylinder with the intermediate change wheels or friction
gear conveying the power to skeleton shaft on which is cam head and-gate lifter-
thereby causing the sheets of paper. to pass through the Machine in.any-position.
Dated this 30th day of May 1889.
JOHN SHAW.
