PROVISIONAL SPECIFICATION.
Improvements in Ticket Punching and Registering Machines.
I, JOHN SMITH COMRIE, Civil Engineer, of 7 & 8, Great Winchester
Street, E.C., London, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the improvement of ticket punching & registering
machines, & particularly that of Patent No. 14,694 1886 in which it is proposed to
be used by mutual consent & arrangement.
By its means one coiled spring is made to do duty for the two blade springs now
controlling pawls of register ratchet wheels, one of the pawls being reversed. The
invention also prevents the piling of punchings in hopper by means of a second
plunger or arm which pushes away the punches from back of die & it is actuated,
like the first, from the handle or lever.
1 also do away with spring which controls the lever arm or dog which prevents
the lever or handle returning to normal position except a full stroke be made, & I
achieve this by somewhat strengthening the spring which holds driving dog in
position against driving ratchet wheel of register & connecting driving dog with
check dog by means of a pin or bar which is fixed on the under side of driving at
present & now is lengthened to the full depth of case & is fitted into a hole in said
check dog so that the two dogs move simultaneously, being thus locked or tied
together, & the spring actuating or controlling driving dog at present, is thus made
to actuate or control both.

COMPLETE SPECIFICATION.
Improvements in Ticket Punching and Registering Machines.
I, JOHN SMITH COMRIE, of 7 & 8, Great Winchester Street, in the City of
London, Civil Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to improvements in the well known bell punches for
punching tickets on omnibuses, tramways and elsewhere, and recording or
registering the number of tickets so issued.
This invention is shown in the annexed drawings in which
Fig. 1 is a general plan-view of a punch embodying this invention.
Fig. 2 is an elevation of certain parts of this punch seen along line II Fig. 1
looking towards the handle of the punch.
Fig. 3 is a plan partly in section of portions of the mechanism.
Fig. 4 is an elevation of the pawls or dogs actuating the registering wheels
seen on line I I I I Fig. 1 looking towards the handle of the punch.
Fig. 5 is a plan of the spring actuating these pawls.
A is the lever operating the internal parts as usual. B is the pawl or dog
driving the ratchet wheel C. The dog B has a pin B¹ extending downwards and
engaging with the spring D and also with an arm E. This arm E by pin e engages
with the lock plate E- which prevents the return motion of lever A unless its
movement or stroke has been completed.
Heretofore two springs were required for this check-motion but by lengthening
the pin B' until it engages with the arm E and by making the spring D somewhat

one spring.

The descent of the arm A also actuates the pawls or dogs F and which act
upon the counting mechanism. Now as usually constructed each punch requires
two springs for these two pawls and these are usually flat springs
springs. By arranging these pawls in the manner shown in the dra vings I am
enabled to use one spring for both, thus further simplifying the construc on of the
punch. I employ the coiled spring 4, separately shown in Fig. 5. As will be seen
in Figs. 1 & 4 this spring is mounted on the same stud as the pawl G. One end
of the spring engages with a notch in the pawl F the other end g¹ with a notch in
pawl or dog G. When arm A is pressed down the part a thereof is carried against
the part of the pawl F and carries the other end towards the counting wheel sec
Fig. 1 and also Fig. 3. The dog B at the same time turns the wheel c one tooth
and the pawl G is also operated. When the lever A is released and carried back
to its position of rest by the helical spring A¹ the spring H carries the dogs for
pawls F and G back to their normal position.
J is the chamber receiving the discs of paper or card punched out of the ticket.
These discs, commonly known as "punchings" are apt to accumulate in front of
the punch or die, that is to say at j. In order to obviate this I attach to the
extension a¹ of the arm A an arm or second plunger K carried forward at each
descent of lever A. and its corner k will break up any accumulation of punchings
at j. The parts not referred to in the above description are of the usual
construction.
In conclusion I have to point out that I am well acquainted with the contents of
the Specification of Letters Patent No. 14694 dated 12th November 1886 and
that I do not claim anything therein shown but
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 punching and registering apparatus the combination of the pawl
or dog B, pin Band spring D with arm E so as to enable the spring D to act upon
the arm E (with which pin B' is made to engage) as well as upon the pawl Bas
and for the purpose set forth.
2) In a ticket punching and registering apparatus the arrangement of the
spring H acting upon the pawls F and G as set forth and shown in the drawing
and for the purpose hereinabove specified.
3) In a ticket punching and registering apparatus the second plunger or arm K
provided for the purpose of breaking up accumulations of punchings at j.
