IMPROVEMENTS IN PRINTING " MACHINERY.”
Year: 1880

page_text: LETTERS PATENT to Frederick Payne, of Otley, in the County of York,
Machine Maker, for an Invention of "IMPROVEMENTS IN PRINTING
"
MACHINERY.”
PROVISIONAL SPECIFICATION left by the said Frederick Payne at the
Office of the Commissioners of Patents on the 21st October 1880.
FREDERICK PAYNE, of Otley, in the County of York, Machine Maker.
"IMPROVEMENTS IN PRINTING MACHINERY."
This Invention has reference to the stopping cylinder machine, or what is known
as the "Wharfedale machine." In the process of printing it is necessary from time
to time to stop the rotary motion of the cylinder, also the motion of the grippers
and feeding board, and the object of this Invention is to arrange the mechanism so
that these parts can be stopped at the proper time, and also to arrange the stopping
mechanism that it can be set or fixed ready for action during any portion of stroke
either backward or forward, and this I accomplish by the use of a horizontal
sliding bar caused to slide backward and forward by means of a cam on the crank
shaft. One end of this horizontal sliding bar is made taper or V shaped, and it is
set opposite to a horizontal lever also having one end taper or V shaped, and the
two are so arranged that when the cylinders and grippers and feeding board are
required to be in motion the horizontal bar slides under the taper lever, but when
the cylinder and grippers and board are required to be stationary the attendant
operates a handle which brings into position a small cam allowing a spiral spring to
lift up the taper lever into such a position that on the return traverse of the
sliding bar it is caused to slide up the incline of the lever, by which means the
taper end of the sliding bar is raised, lifting up the ordinary vertical rod, which
disconnects the parts employed in operating the cylinder grippers and feeding
board.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Frederick Payne in the Great Seal Patent Office on the 21st
April 1881.
FREDERICK PAYNE, of Otley, in the County of York, Machine Maker.
"IMPROVEMENTS IN PRINTING MACHINERY."
This Invention has reference to the stopping cylinder machine, or what is known
as the "Wharfedale machine." In the process of printing it is necessary from time
to time to stop the rotary motion of the cylinder, also the motion of the grippers
and feeding board, and the object of this Invention is to arrange the mechanisin so
that these parts can be stopped at the proper time, and also to arrange the stopping
mechanism that it can be set or fixed ready for action during any portion of stroke
either backward or forward, and this I accomplish by the use of a horizontal
sliding bar caused to slide backward and forward by means of a cam on the crank
shaft. One end of this horizontal sliding bar is made taper or V shaped, and it is
set opposed to a horizontal lever, also having one end taper or V shaped, and the
two are so arranged that when the cylinders and grippers and feeding board are
required to be in motion the horizontal bar slides under the taper lever, but when
the cylinder and grippers and board are required to be stationary the attendant
operates a handle which brings into position a small cam, which presses down a
spiral spring, allowing the taper lever to drop into such a position that on the
return traverse of the sliding bar it is caused to slide up the incline of the lever,
by which means the taper end of the sliding bar is raised, lifting up the ordinary
vertical rod which disconnects the parts employed in operating the cylinder and
grippers and feeding board.
In order that the Invention may be more fully understood, I have given referenco
to the accompanying Sheet of Drawings, wherein Fig. 1 is elevation of so much of
a "Wharfedale printing machine as is necessary to shew my improvements. A. is
the cylinder, and B the vertical rod which disconnects the parts employed in
operating the cylinder and grippers and feeding board, all arranged in the ordinary
manner; C is the horizontal sliding bar, which is caused to move backward and
forward by means of the cam D on the crank shaft E. The horizontal lever or bar
is shewn at F, which, when required, can move upon a pin e for purposes hereinafter
explained.
The action of the apparatus is as follows:-When the machine is at work, and
the cylinder and grippers and feed-board are not required to be stopped, the various
parts are in the position as shewn in Fig. 1, the end of the bar C sliding underneath
the end of the bar F, but when the attendant requires the cylinder and grippers
and feed-board to be stationary without stopping the whole machine he turns the
handle G (say, in the direction of the arrow), operating the cam H, which presses
down the part I and spiral spring J, lowering the end of the bar F, as shewn in
Fig. 2, so that on the return stroke of the sliding bar C the latter will be caused to
rise, and acting under the lug c on the vertical rod B, which will be lifted and
thereby disconnect the parts employed in operating the cylinder, grippers, and
feeding board. When the cam is operated upon in the reverse way the spiral
spring J will lift the part I, placing the lever F in the position as shewn in Fig. 1.
To prevent breakages, if the points a and b of the bars C and F should "prop" or
come into contact a slot K is formed in the bar F, which would allow the said bar
to be pushed backward; L is a spring for bringing the bar back into position again.
When the bar F is down ready for the bar C to slide over it the bar F cannot bo
pushed backward in the slot K, as the .lug d is in contact the fixed projection f,
which keeps the same rigid.
Having now described the nature of the said Invention, and described with the
aid of Drawings how the same may be carried into practice, I would have it

page_text: understood that I do not limit myself to the precise details or configuration of the
parts I have described and shewn, as the same may be varied or modified without
departing from the nature of my said Invention, but what I do claim and desiro to
be secured by Letters Patent is,-
The combined' use of the bars C and F, operated in the manner and for the purpose
substantially as herein shewn and described.
In witness whereof, I, the said Frederick Payne, have hereunto set my hand
and seal, this Eighteenth day of April, in the year of our Lord One
thousand eight hundred and eighty one.
FREDERICK PAYNE. (LS.)
