IMPROVEMENTS IN PRINTING MACHINERY
Year: 1885

page_text: I, ALFRED JOSEPH SANDERS, of Sackville Works, Meanwood Road, Leeds, in
the County of York, Printer's Engineer, do hereby declare the nature of my
invention for IMPROVEMENTS IN PRINTING MACHINERY, to be as follows:-
This invention refers to that class of machine which is fitted with a cylinder
having an intermittant rotary motion, generally known as the " Wharfedale."
The object of my invention is to provide an easy, expeditious, & safe way of
stopping the motion of the Cylinder, Grippers, Points, & Feedboard, whilst the
rest of the machine continues to run; and this, in such a manner, that (there being
only one period during which they can be stopped & started) the operator may
be able to actuate the handle which finally stops or starts them, at any time, & at
any part of the revolution of the machine.
The means I use may be briefly described as follows:-A bar, actuated by a
cam on the Crank shaft, has an advancing and retiring motion given to it, in the
direction of its length, & towards one end of a bell crank lever, (fixed further
along the frame); the end of the bar, however, stops short of the bell crank lever,
at such a distance as to allow an intermediate bar (which latter is hinged to the
beforementioned end of the bell crank lever) to be brought into, or thrown out of,
line with the advancing bar. This intermediate bar is in connection with the
stopping & starting handle, & the whole is arranged in such a way that, when the
intermediate bar is in, or out, of line, the bell crank lever is actuated or left at
rest, as the case may be-The other end of the bell crank lever is connected with
the "crutch," or vertical bar, which operates in the usual way.
The end of the intermediate bar has a V shaped groove cut in it, & part of this
groove is further fitted with a sliding piece (acted on by a spring) which gives
way in case of danger.
The end also of the advancing bar is pointed so as to fit into the groove at the
head of the intermediate bar. A short length of this advancing bar is hinged so
as to allow the end to swing out of the way of the intermediate bar in case this
latter is brought into line at the time when the former has already travelled
forward & into the position which the end of the intermediate bar occupies when
raised.
The stopping & starting rod raises the intermediate bar by means of a toe,
which can be depressed, at any time, leaving the intermediate bar free to follow aô
soon as it is released by the action of the cam withdrawing the advancing bar.

page_text: I, ALFRED JOSEPH SANDERS, of Sackville Works, Meanwood Road, Leeds, in
the County of York, Printer's Engineer, do hereby declare the nature of my
invention for IMPROVEMENTS IN PRINTING MACHINERY, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention refers to that class of machine which is fitted with a cylinder
having an intermittant rotary motion, generally known as the "Wharfedale."
The object of my invention is to provide an easy, expeditious, & safe way of
stopping the motion of the Cylinder, Grippers, Points, & Feedboard, whilst the rest
of the machine continues to run; and this, in such a manner, that (there being
only one period during which they can be stopped & started) the operator may be
able to actuate the handle which finally stops or starts them, at any time, & at
any part of the revolution of the machine.
The means I use may be briefly described as follows:-A bar, actuated by a
cam on the Crank shaft, has an advanving and retiring motion given to it, in the
direction of its length, & towards one end of a bell crank lever, (fixed further along
the frame); the end of the bar, however, stops short of the bell crank lever, at
such a distance as to allow an intermediate bar (which latter is hinged to the
before mentioned end of the bell crank lever) to be brought into, or thrown out of,
line with the advancing bar. This intermediate bar is in connection with the
stopping and starting handle, and the whole is arranged in such a way that, when
the intermediate bar is in, or out, of line, the bell crank lever is actuated or left at
rest, as the case may be. The other end of the bell crank lever is connected with
the "crutch," or vertical bar, which operates in the usual way.
The end of the intermediate bar has a V shaped groove cut in it, & part of this
groove is further fitted with a sliding piece (acted on by a spring) which gives
way in case of danger.
The end also of the advancing bar is pointed so as to fit into the groove at the
head of the intermediate bar. A short length of this advancing bar is binged so
as to allow the end to swing out of the way of the intermediate bar in case this
latter is brought into line at the time when the former has already travelled
forward & into the position which the end of the intermediate bar occupies when
raised.
The stopping & starting rod raises the intermediate bar by means of a toe,
which can be depressed, at any time, leaving the intermediate bar free to follow as
soon as it is released by the action of the cam withdrawing the advancing bar..
In order to fully explain my invention I have annexed a drawing in which
Figs. 1 & 2, are side elevations. The former shows the intermediate bar in gear,
whilst the latter shows it out of gear. The same letters refer to the same parts in
all the figures.
The bar A, which is guided by the slot A¹ & also by the bracket A2, has an
advancing and retiring motion given to it, at the required times, by a cam B, fixed
on the Crank shaft C-or by any other suitable means.
This bar ends in a swing

page_text: piece D, hinging at D¹ in such a manner that whilst free to swing upwards it can
fall no lower than shown on the drawing. The end of this swing piece is also
suitably pointed.
E is the fulcrum of a Bell Crank lever which has one end F connected to the
intermediate bar G whilst the other end H is in connection with the crutch or
vertical bar I. The intermediate bar G in addition to its connection with the bell
crank lever, is acted upon by a toe on the bar K and is thus connected to the
stopping and starting handle L. This latter is fitted with a quadrant L' and
stops Land L³. The toe on the bar K is provided with a roller K¹ to lessen
friction and wear and the foot of the bar is guided by a pin & slot K². The end
of the intermediate bar G has a V shaped groove cut in it to suit the pointed end
of the swing piece D, & an upper part of this groove is further fitted with a
sliding piece G¹ kept in position by the spring G² fixed behind it. The object of
providing the sliding piece is to guard against the danger which might arise were
the point of the swing piece D to come into fixed contact with the end G¹ of the
intermediate bar. Were this to happen now the sliding piece would fall back and
compress the spring and the crutch I would not be actuated, and finally the swing
piece would fall into gear when the bar A was next fully withdrawn.
In case the rod K is lowered before the required time nothing will be effected
until the bar A has retired & has thus permitted the intermediate bar to fall. On
the contrary if the intermediate bar be raised when the swing piece D is in its
advanced position this latter is lifted upwards & does not fall into gear until it
has again retired.
From what has already been described it will be seen that the attendent can at
any time throw the stopping and starting handle over so as to actuate or stop the
cylinder &c. but the effect will not be produced until the proper time has arrived.
It is scarcely necessary to state that the weight of the intermediate bar causes
its fall when permitted, but springs could be made to assist the action if found
necessary.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The apparatus forming the complete stopping and starting motion, con-
structed, arranged, and operated as described and shown on the drawing, with the
object & for the purpose set forth.
