Improvements in Ticket Punches.
I, THOMAS GIBSON, of 26, Galveston Road, East Putney, in the County of Surrey,
Instrument Maker, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to insure that all the series of operations, namely,
punching the ticket, ringing the bell and operating the registering mechanism, must
be performed before another ticket can be punched.
The punch works in the usual manner in a hole passing across jaws formed in a
block, and is pivotted to a lever operated by a pusher. The punch is prevented from
descending when there is no ticket in the jaws, by an arm pivotted to the lever which
comes against a slide carrying a projection which protrudes between the jaws, through
a slot in the block. When a ticket is thrust between the jaws, it engages with the
projection and moves the slide against the action of a spring, tending to keep it in the
locked position.
The pusher and punch are now free to move, the arm passing through a slot in the
slide.
On the lever is pivotted a double pawl, one-tooth of which operates the ratchet
wheel of the recording mechanism, and the other tooth engages with a dog on the
backward movement of the pusher if the recording mechanism has not been operated.
When however the recording mechanism has been operated, the tooth of the ratchet
wheel turns the double pawl about its pivot so that it does not engage with the
dog.
The end of the pusher in its descent engages with a spring catch pivotted to the
bell haniner, and in passing it rings the bell, and it does not escape from beneath
this catch until it has almost reached its highest position again.
The pusher is raised by a helical spring in place of the usual flat or bow spring.
Dated this 20th day of September 1898.
İmprovements in Ticket Punches.
I, THOMAS GIBSON, of 26, Galveston Road, East Putney, in the County of Surrey,
Instrument Maker, 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 this invention is to insure that all the series of operations, namely,
punching the ticket, ringing the bell, and operating the registering mechanism, must
be performed before another ticket can be punched.

page_text: The punch works in the usual manner in a hole passing across jaws formed in a
block, and is pivotted to a lever operated by a pusher. The punch is prevented from
descending when there is no ticket in the jaws, by an arm pivotted to the lever which
comes against a slide carrying a projection which protrudes between the jaws through
a slot in the block. When a ticket is thrust between the jaws, it engages with the
projection and moves the slide against the action of a spring, tending to keep it
in the locked position.
The pusher and punch are now free to move, the arm passing through a slot in the
slide.
The drawings shew a ticket punch made in accordance with this invention.
Figure 1 is a side elevation, and Figure 2 is the same with the outside cover
removed.
a is the pusher, and the jaws for receiving the ticket. c is the hinged cover of
box d, into which the pieces punched out of the tickets fall.
The punch e, works in the usual manner in a hole f, passing across the jaws b,
formed in a block g, and is pivotted to a lever h, itself pivotted at ¹, and operated by
the pusher a. The punch e is prevented from descending when there is no ticket in
the jaws, by an arın i pivotted to the lever h, which comes against a slide j, shewn in
plan in Figure 3, carrying a projection j', which protrudes between the jaws b, through
a slot g' in the block g. When a ticket is thrust between the jaws, it engages with
the projection j¹, and moves the slide j, against the action of a spring k, tending to
keep it in the locked position. The pusher and punch are now free to move, the
arm passing through a slot 72, in the slide 1, its path being regulated by the pin ¹.
On the lever is pivotted a pawl l, the tooth of which is always pressed in the
direction of a pin m, by a blade spring fixed to the pawl l, and engaging with a
lug n, on the arm i, as will be seen in the end view shewn in Figure 4. When the
pusher is pressed down, the pawl operates the ratchet wheel o of the recording
mechanism.
At the end of the lever h, are teeth 2, which as the lever moves downwards, engage
with a catch p.
The catch P is pivotted at p³, and is pressed upwards by the spring q. On the
catch is a pin p2, which engages with the hammer of the bell, and turns it
against the spring & The catch p prevents the lever h from moving upwards, until
all the teeth have passed over it, these teeth being such that the recording
mechanism must have been operated before the upward movement. When all
the teeth h² have passed the catch, the hammer flies back and rings the
bell 7*1.
After the operations are completed the pusher is raised by the helical
spring t.
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. A slide locking the mechanism until pushed inwards by the ticket, substantially
as described.
2. The combination of a slide and an arm actuating the mechanism and operated
by the handle or pusher, the arm being locked by the slide when the latter is in its
forward position, substantially as described.
3. Ticket punches substantially as described and illustrated in the drawings.
