An Improved Automatic Brake for Lithographic and Letter Press
Printing Machines.
I JONAS RUSBY of 30 Purton Street, Dewsbury Road, Leeds, Mechanic, do hereby
declare the nature of this Invention to be as follows:-
The object of my invention is to construct a self acting brake which does not
interfere with pressure during printing, as it neither takes pressure off nor puts it on.
I construct the brake wheel preferably with a solid back and a flange or rim, on
the boss inside or out or on any convenient part of the shaft of the brake wheel I cast
or fix two swells, which are of suitable length and suitable distances apart to put on
the brake at the proper time, the brake consists preferably of a semicircular block
acting upon the inside or other suitable part of the flange of the brake wheel, the
block is carried in a suitable slide, and upon the inside of the block is a runner
carried in a steel or other suitable neck or bush formed with a recess which can be
partially filled with oil, so that it is self oiling, the bush is adjustable by means of
Screw and lock nuts or by springs either metallic or indiarubber, the action is as
follows:-
As the projections on the shaft or boss come in contact with the runner the brake is
put on and kept on during such contact as required.

1 JONAS RUSBY of 30 Purton Street Dewsbury Road Leeds, in the county of York
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:-
The object of my invention is to construct a selfacting brake which does not
interfere with pressure during printing, as it neither takes pressure off nor puts it on.
I construct the brake wheel preferably with a solid back and flange or rim; on the
boss, inside or out, or in any convenient part of the shaft of the brake wheel I cast or
fix two swells which are of suitable lengths and suitable distances apart to put on the
brake at the proper time. The brake consists preferably of a semicircular block
acting upon the inside of the flange of the brake wheel. A slide or sliding bush is
carried by the brake block, in the centre of the slide is a screw with lock nuts and
underneath a spring which regulates the pressure of the brake, a steadying slide is
attached to the brake block in any suitable manner and works within a suitable
bracket under the centre of the brake wheel, fixed on the frame side, a spring relieves
the brake when not required. Upon the inside of the block is a runner carried in the
slide or sliding bush before described or the bush is formed with a recess which can be
partially filled with oil so that the runner is selfoiling. Instead of a single brake
block two brake blocks may be used if required one to act upon the bottom of the
inside of the flange of the brake wheel and the other against the top, both constructed
as before described.
The action is as follows:-As the projections on the shaft or boss come in contact
with the runner the brake is put on and kept on during such contact as required.
DESCRIPTION OF DRAWINGS.
Fir 1 is a front elevation of my annaratna Fio 2 is a section of Fig.
The
Kia 1 is a front elevation of my annaratna Fio 2. is 3 section of Fiơ. 1. The
rest of the figures are details.
The brake wheel has preferably a solid back A and a flange or rim K; on the boss
inside or out, or on any convenient part of the shaft of the brake wheel I cast or fix
two swells G and G which are of suitable lengths and suitable distances apart to put
on the brake at the proper time the brake consists preferably of a semicircular
block B acting upon the inside of the flange of the brake wheel. A slide or sliding
bush C is carried by the brake block B, in the centre of the slide is a screw H with
lock nuts H¹ and underneath a spring J which regulates the pressure of the brake, a
steadying slide F is attached to the brake blocks in any suitable manner and works
within a suitable bracket E under the centre of the brake wheel, fixed on the frame
side, a spring L relieves the brake when not required.

page_text: Upon the inside of the block is a runner D carried in the slide or sliding bush
before described or the bush is formed with a recess M which can be partially filled
with oil so that the runner is selfoiling. Instead of a single brake block two brake
blocks may be used if required, one to act upon the bottom of the inside of the
flange K of the brake wheel and the other against the top, both being constructed as
before described.
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 general arrangement and construction of an inside automatic brake as shewn
and described.
2. The slide or sliding bush such as C applied inside or out for brake purposes as
shewn and described.
3. The use and employment of swells (or their equivalents) upon the boss or upon
any convenient part of the cylinder shaft for the purposes shewn and described.
4. The use and employment of a brake block B operating upon the flange K of the
brake wheel either singly at the bottom or double acting upon both top and bottom as
hereinbefore described.
