An Improvement in Ticket Printing Machines.
I PETER HOOKER of Pear Tree Court Farringdon Road London E.C.
Engineer do hereby declare the nature of this invention to be as follows:-
This my invention relates to an improvement in ticket printing mchs. & my
invention consists of the details of mechanism & combination of parts hereinafter
described. & set forth.
In ticket printing machines hitherto constructed it has been customary to print
the tickets during their passage through the mch. upon one side only the ticket
blanks being placed in a vertical shoot or guide from which they were delivered
one at a time into a guide in the bridge piece or platen being forced along said
guide by the delivery of the succeeding ticket. During their passage they received
the impression from the type such impression being made upon one side of the said
ticket. After traversing the guide in the bridge they were made to ascend a shoot
or guide corresponding in form to the feeding shoot. If it was desirable that both
sides of the ticket should be printed it was necessary that the tickets after the
printing upon one side had been effected should be again passed through the
machine in order that the other side might be printed.
My invention is devised with the object of constructing the mch. in such a
manner that both sides of the tickets shall be printed during the one passage of
the ticket through the machine thereby effecting a considerable economy of time
& labour.
I carry my invention into practice in the following manner. The bridge or
platen of the meh. is made longer than that usually employed the mch. to which it
is applied being wider & having 2 type beds & forms arranged wider & in
alignment with the guide in the said bridge.
The operation of the mch. is as follows. The tickets are fed in succession along
the said guide in the ordinary manner by an oscillating lever, during their passage
they are numbered by the usual mechanism & receive the impression upon one side
of the said ticket from the first set of type. Immediately after passing the said
type the ticket is turned completely over face to face in such a manner that upon
proceeding upon its travel along the guide in the bridge or platten the blank face
of the ticket is presented to the second set of type so that by this means both sides
of the ticket receive an impression.
The reversal or turning over of the tickets is effected by means of a drum or
cylinder which is partly cut away the said drum being mounted midway between
the formes & the axis of rotation being at right angles to the guide in the bridge
piece. The said drum or cylinder has a passage therein which is in alignment with
& registers with the guide in the bridge piece the length of the guide in the drum
is preferably equal to the length of one ticket. An adjustable strip is fixed upon
the face of the guides the object of such strip being to adjust the width of the
guide to the thickness of the ticket.
At one end of the cylinder is loosely mounted a pinion coaxial with the said
cylinder the said pinion carrying upon its inner face a pawl adapted to engage a
ratchet wheel upon the end of said cylinder.so as to rotate the latter in one
direction only. The before mentioned pinion engages with a rack which is mounted
to slide in horizontal guides upon the edge of the bridge the end of said rack being

page_text: connected by a suitable rod or link to the oscillating ticket feeding lever so that
the movement of the latter will impart a reciprocal motion to the rack & thus the
pinion will be alternately rotated in either direction. The drum will therefore
receive a rotary motion during one motion of the rack & remain stationary on the
reverse motion. A locking pawl & ratchet prevents the backward rotation of the
said drum & 1 also provide a spring catch adapted to engage a notch in the drum
to prevent the drum rotating more than a half revolution.
The tickets which are intermittently projected along the guide in the bridge are
in succession forced into the passage through the drum or cylinder which rotating
as before described completely reverses the ticket. After this has taken place the
ticket within the drum is pushed along as the next ticket takes its place the whole
of the tickets being thus in succession reversed. The drum has 2 cam surfaces or
wipers upon the face of the same so as to force the tickets in the guide adjacent to
the drum slightly apart & thus prevent the edges of the ticket within the drum
from contact with the adjacent tickets which would result in preventing the free
working & rotating of the cylinder.

COMPLETE SPECIFICATION.
An Improvement in Ticket Printing Machines.
I PETER HOOKER of Pear Tree Court Farringdon Road 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 relates to an Improvement in Ticket Printing Machines and
my invention consists of the details of mechanism and combination of parts
hereinafter described and set forth.
In ticket printing machines hitherto constructed it has been customary to print
the tickets during their passage through the machine upon one side only the ticket
blanks being placed in a vertical shoot or guide from which they were delivered
one at a time into a guide in the bridge or platen being forced along said guide by
the delivery of the succeeding ticket.
During their passage they receive the impression from the type such impression
being made on one side of the ticket. After traversing the guide in the bridge
they were made to ascend a shoot corresponding in form to the feeding shoot.
If it was desirable that both sides of the ticket should be printed it was necessary
after the printing upon one side of the ticket had been effected as described, that
the latter should be again passed through the machine in order that the other side
might be printed.
My invention is devised with the object of constructing the machine in such a
manner that both sides of the ticket shall be printed during a single passage of
the ticket through the machine thereby effecting a considerable saving of time and
labour.
In order that my invention may be better understood reference is made to the
accompanying drawings in which
Fig. 1 is an elevation of the upper portion of a ticket printing machine shewing
my improvement applied thereto."
Fig. 2 is a plan of the same and
Figs. 3, 4 and 5 are details of parts hereinafter described.
Like letters of reference indicate corresponding parts in all of the figures.
In constructing a machine according to my invention I make the bridge or
platen A longer than that usually employed the machine to which it is applied

page_text: being wider and having two or more type beds and formes a, b, carried upon a
common slide B and arranged in alignment with the guide in said bridge. When
in operation the tickets are fed in succession along the said guide in the ordinary
manner by an oscillating lever C; during their passage they are numbered by the
usual mechanism D and receive an impression upon one side of the said ticket from
the first set of type b. Immediately after passing the said type the ticket is
turned completely over face to face in such a manner that the blank face of the
ticket is presented to the second set of type a so that by this means each side of
the tickets receives an impression.
The reversal or turning over of the ticket is effected by means of a drum or
cylinder E (which may be solid but is preferably of skeleton form as shewn in
Figs. 3, 4 and 5) the said drum being mounted midway between the formes and
having its axis at right angles to the guide in the bridge piece. The said drum or
cylinder has a passage e therein which is an alignment with and registers with the
guide in the bridge piece.
The length of the passage e through the drum is preferably equal to the length.
of one ticket. An adjusting strip is fixed upon the face of the guide to adjust
the width of the passage to the thickness of the ticket.
At one end of the cylinder E is loosely mounted a pinion 9 coaxial with the
said cylinder the said pinion carrying upon its inner face a pawl h adapted to
engage a catch or toothed plate upon the end of said cylinder so as to rotate
the latter in one direction only. The before mentioned pinion g engages with a
rack F which slides in horizontal guides upon the edge of the bridge the end of
said rack F being connected by a suitable rod or link to the oscillating ticket
feeding lever C so that the movement of the latter will impart a reciprocal motion
to the rack F and thus the pinion g will be alternately rotated in either direction.
The cylinder E will therefore receive a rotary motion during one motion of the
rack and remain stationary on the reverse motion. A locking pawl p prevents
the backward rotation of said drum and I also provide a spring latch adapted
to engage a notch n in the cylinder to prevent the latter rotating more than a half
revolution.
The tickets which are intermittently projected along the guide in the bridge are:
in succession forced into the passage through the drum or cylinder E which
rotating as before described completely reverses the ticket. After this has taken
place the ticket within the drum is pushed along as the next ticket takes its place
the whole of the tickets being thus in succession reversed.
same so
The drum or cylinder E has two cam surfaces or wipers c upon the face of the
as to force the tickets in the guide adjacent to the cylinder slightly
apart and thus prevent the edges of the ticket within the cylinder from contact.
with the adjacent tickets which would possibly interfere with the free rotation of
the cylinder.
Although I have described a rack and pinion for operating the cylinder I wish.
it to be understood that I do not wish to confine myself to this method as any
other suitable mechanical device may be substituted for the said purpose without
departing from the spirit of my invention.
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
1. In a ticket printing machine the combination of two or more type formes.
arranged in the same plane with the ticket guide in the bridge or platen and a
rotary device for turning over the tickets adapted to make a half revolution
simultaneously with each impression the whole being constructed arranged and
operating substantially as described and illustrated.
2. The combination with a ticket printing machine of a rotary cylinder having
a passage therethrough in alignment with the guide in the bridge or platen and
means for imparting a half revolution to said cylinder at each impression stroke

as described and illustrated.
