PROVISIONAL SPECIFICATION.
Improvements in and relating to Ticket Printing Machines, partly
applicable to other Printing Machines.
I PETER HOOKER, of Pear Tree Court Farringdon Road E.C. Engineer do
hereby declare the nature of this invention to be as follows:-
This my invention has reference to improvements in and relating to ticket-
printing machines the said improvements being also partly applicable to other
printing machines and my invention consists of certain details of construction and
arrangement of parts hereinafter described and set forth.
My invention has reference firstly to the mechanism for operating the several
parts from the driving shaft of the machine and the manner in which I carry out
this part of my invention consists in operating the slidė or bed carrying the type
beds and numbering mechanism by means of an eccentric and strap upon the
driving shaft which is connected directly to the said slide. The said slide also
operates the inking mechanism and ticket feed the operating levers of which are
connected to the said slide by means of links or rods.
My invention also relates to the inking mechanism and ink feed for ensuring an
equal supply of ink to the machine while in operation.
Hitherto it has been customary to supply a fresh charge of ink to the machine
while in motion by means of a hand roller at intervals as required which caused
the printing on the tickets to gradually become fainter as each charge of ink
became exhausted. Now I propose to provide the machine with an automatic ink
feed in order to overcome this objection and in carrying out this portion of my
invention provide an ink-duct or trough adapted to form a reservoir for a supply
of ink and mechanism for causing the ink contained therein to be evenly transferred
to the inking roller and type.
The said mechanism consists of a roller to receive a supply of ink from said duct
and a feed roller adapted to intermittently transfer a portion of the ink on said
roller to the distributing roller from which in its turn the type inking roller is
supplied. The distributing roller is rotated from the driving shaft of the machine
by means of a chain and sprocket wheels on the respective shafts or other
equivalent means and the main supply roller is rotated from the distributing roller
shaft by spur gearing. Upon the axis of the said main supply roller is mounted a
dise having a cam-groove in the face thereof in which engages a stud upon one
arm of a bell crank lever mounted upon the framing at a suitable point the other
arm of said lever forming one of the bearings for the shaft of the feed roller the
opposite end of said shaft being carried in a rocking lever in a similar manner.
The parts are so adjusted that as the cam-disc before referred to is rotated the
bell-crank lever is oscillated upon its fulcrum and the feed roller carried by said
lever is caused to alternately contact with the main supply roller from which it
receives a supply of ink and the distributing roller to which the ink is transferred.
In order to ensure the even distribution of the ink I prefer to arrange the cam
disc so as to cause the feed roller to remain longer in contact with the distributing
roller which allows a better distribution of the ink and I also provide throwing off
mechanism for the purpose of regulating the supply of ink to the feed roller prior
to the running of the machine.
The ink duct or reservoir may be divided into a number of compartments by
suitable divisions or equivalent means the rollers receiving the ink being similarly
divided and by adopting this arrangement either a single colour or two or more
colours may be used simultaneously upon the machine at will.

page_text: The part of my invention just described relating to the inking mechanism is also
applicable to other printing machines as will be readily understood by those skilled
in the art to which it appertains the construction and arrangement of the parts
being slightly modified to suit the machine to which it is applied.
I also connect the type inking roller carriage to the operating lever by means of
a pin which may be removed when it is desired to withdraw the said roller the
removal of the pin allowing the roller carriage to be drawn out from the rear of
the machine.
There has also been considerable difficulty hitherto experienced in inserting the
chases in the machine and in order to facilitate this operation I form the front of
the box with a vertically sliding plate which is depressed when the chase is inserted
and is secured in its raised position after the insertion of the same thus securely
locking the chase in position."

COMPLETE SPECIFICATION.
Improvements in and relating to Ticket Printing Machines, partly
applicable to other Printing Machines.
1 PETER HOOKER of Pear Tree Court Farringdon Road London E.C.
Engineer 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 my invention has reference to improvements in and relating to ticket
printing machines the said improvements being also partially applicable to other
printing machines and my invention consists of certain details of construction and
combination and arrangement of parts hereinafter described and set forth.
The accompanying drawing illustrates the manner in which 1 carry my invention
into practice.
Fig. 1 of the said drawing being a cross section of a portion of a ticket printing
machine having my improvements applied thereto.
Figs. 2 & 3 are details of the same hereinafter described.
My invention has reference firstly to the mechanism for operating the several
parts from the driving shaft of the machine and the manner in which I carry out
this part of the invention consists in operating the slide or saddle A carrying the
type beds and numbering mechanism by means of an eccentric upon the main
driving shaft a the strap e of the said eccentric & being connected to a pin upon
the before mentioned slide or saddle. The slide A also operates the inking
mechanism and ticket feed the bell crank levers for actuating which are connected
to the said slide by means of links or rods which are journalled on pins projecting
from the said slide..
My invention also relates to the inking mechanism and ink feed for ensuring an
equal supply of ink to the machine while in operation.
Hitherto it has been customary to supply a fresh charge of ink to the machine
while in motion by means of a hand roller at intervals as required which caused
the printing on the tickets to gradually become fainter as each charge of ink
became exhausted. Now I provide the machine with an automatic ink feed to
overcome this objection and in carrying out this portion of my invention I provide
an ink duct or trough D adapted to form a reservoir for a supply of ink and
mechanism for causing a supply of ink contained therein to be evenly transferred
to the inking roller and type. The said mechanism consist of a roller e to receive
a supply of ink from the said duct d and a feed roller fadapted to intermittently
transfer a portion of the ink on said roller e to a distributing roller from which
the type inking roller is supplied.

page_text: A pinion (rotated by means of a chain wheel upon its axis which is connected by
an endless chain with a similar wheel upon the driving shaft of the machine or other
means) engages corresponding toothed wheels upon the shafts of the supply roller e
and the distributing roller g thereby imparting rotary motion to the said rollers.
The before mentioned pinion is mounted upon an eccentric shaft or boss thereby
allowing the disengagement of the pinion from the toothed wheel on the axis of
the supply roller for the purpose of readily throwing the latter out of action.
Upon the axis of the supply roller e is mounted a disc i having a cam groove in
the face thereof in which engages a stud jupon one arm of the bell crank lever k
mounted at a suitable point upon the framing the other arm of said lever forming
one of the bearings for the shaft of the feed roller the other end of said shaft
being carried on a rocking lever in a similar manner.
The whole of the parts are so adjusted that as the cam disc i before referred to
is rotated the bell crank lever is oscillated upon its fulcrum and the feed
roller carried by said lever is caused to alternately contact with the main supply
roller e from which it receives a supply of ink and the distributing roller g to
which the ink is transferred.
The bell crank lever & has a projecting lug thereon carrying a stud & which
engages a cam groove on the periphery of the disc i (as shewn more clearly in
Fig. 2) and by this means a rubbing or vibratory motion is imparted to the roller f
thus effecting a more uniform and even distribution of the ink. I also prefer to arrange
the cam groove in the face of the disc i so as to cause the feed roller to remain
longer in contact with the distributing roller which also facilitates the better
distribution of the ink.
The ink duct or reservoir d may also be divided into a number of compartments
by suitable divisions or equivalent means the rollers receiving the ink being
similarly divided and-by adopting this arrangement either a single colour or two or
more coloured inks may be used simultaneously upon the machine at will.
This part of my invention relating to the inking mechanism is also applicable to
other printing machines as will be readily understood by those skilled in the art to
which it appertains the construction and arrangement of the parts being slightly
nodified to suit the machine to which it is applied.
I also connect the type inking roller carriage m to the operating lever o by
means of a pin p which may be removed when it is desired to withdraw the said
roller, the removal of the pin p allowing the carriage m to be drawn out of its
guides from the rear of the machine the end of the said guides being open.
There has also been considerable difficulty hitherto experienced in inserting the
chases and in order to facilitate this operation I form the front of the box with a
vertically sliding plate R (shewn in front elevation in Fig. 3) which is depressed
when the chase is inserted and is secured in its raised position by the screw after
the insertion of the same thus securely locking the chase in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvements in and relating to ticket printing machines substantially as
described and illustrated in the accompanying drawings.
Dated this 2nd day of August 1894.
