Improvements in Ticket Punching and Recording Devices.
I, DAVID MCGILL, of 135 Camberwell New Road, in the County of Surrey.
Veterinary Surgeon do hereby declare the nature of my invention and in' what
manner the same is to be perfornied to be particularly described and ascertained
in and by the following statement :-
My invention relates to ticket punching and recording devices, and has for
object the provision of means whereby the operation of the punching device is
prevented, until a ticket or other article is placed in proper position in the device
for punching, the punching device being freed froin the influence of the locking
device after the edge of the punch has partially cut the ticket or other material.
My invention is designed to overcome the great difficulties that have obtained in
machines previously made, with reference to fraudulent use of the machine by
conductors and others, in which, means have been provided for locking the
punching and recording mechanism, until some resistance, such as a ticket, is
interposed between the punch and die. It lias however been found, that in a
variety of ways the locking mechanism can be manipulated and unlocked by an
unscrupulous person, and the punching mechanism can be operated without a piece
of the ticket being punched out as a record of' a fare taken.
This result may be achieved for instance by a hair or fine wire being applied to
tie the locking gear back into the unlocked position, so that the punching operation
can take place whether a ticket is put into the space between the punch and die or
not, as the case may be.
My invention consists in arranging upon the punch a locking device, or a
tumbler, connected to locking device, in such a way, that the edge of the punch
is so situated with reference to said locking device, or operative tumbler, that the
edge of the said punch protects the locking device by cutting into the ticket or
other article before the contact of the locking device with the ticket is sufficiently
made to unlock the punch, and therefore, when the punch is unlocked, a clipping
must be deposited in the receptacle as a result of the operation.
In order that my invention may be the better understood, I will now proceed to
describe the same in relation to the accompanying drawings hereunto annexed,
reference being had to the letters and figures marked thereon. Like letters refer
to like parts in the various figures:
Figure 1 is a sectional elevation of one forin of punch, according to my invention,
the punch being shown after having made a partial movement downwards and
being in the locked position, and is thereby prevented from further downward
movement, sufficient to operate the recording mechanist, or allow any record to be
made by a clipping being deposited.
Figure 2 is a similar view with the ticket shown in place, and the ticket clipping
n the act of falling through the die.
Figure 3 is a detail view of the punching device showing the ticket in place,
operating the locking device, so as to put it into the unlocked position to allow the
ticket to be punched.
Figure 4 is a plan of the die and
Figs. 5 6 and 7 are different views of the punch..
To carry my invention into effect, I'arrange operative means such, as a lever A,

page_text: within a die D. The punch C is made with a flat back the edge of which is not
adapted to cut, and in this back a recess F is made in the body of the punch
extending to the bottom end thereof. Within this recess is pivotted the locking
device or means for operating a locking device; I shall here describe the punch as
having the locking device placed therein, but it must be understood that the
alternative is clearly within the essence of my invention.
The locking device as shown in the drawing consists of a tumbler or detent E,
which is pivotted within the recess F of the punch C. This tumbler and detent E
has on its lower side a small projecting edge H, adapted to engage against the
edge of the die D when the tumbler or detent E is in its lowest position, the edge
of the tumbler or detent E is so formed at the back of the notch or edge H, so
that when the detent E comes in contact with the ticket, the detent E will slide
upon the said ticket and be turned around its axis, so as to allow the punch to be
moved down into the die. In order to maintain the tumbler Ę in its normal locking
position, a small spring G is supported at one end upon the die block, the other end
being free to act upon the detent E to force it into its lowest position. The cutting
edge of the punch C is so made that it protects the detent E from being operated
by anything else than that from which the punch C can take a clipping.
To carry this out it will be noticed from the drawing that the punch has its
edge of an undulating form, the front and back portions being prominent while the
part of the edge between these said portions is set back. In this manner the.
tumbler E is entirely protected from being tampered with and the punch enters a
portion of the ticket before the tumbler E is completely operated into the unlocked
position, so that unless the punching operation is completed, the ticket cannot be
withdrawn, and therefore the device cannot be rung off, unless a clipping is left as
a record of the transaction. The part of the ticket that is not cut by the punch
on the partial operation of the device before the locking device is unlocked, is
sufficient to form a platform, rigid enough to move the tumbler into the position
so that the device is unlocked. It will be noticed that the tumbler has only to be
moved sufficiently to allow the notch or projection H to pass the edge of the die,
when the specially curved edge of the tumbler acting against the die, tends to
continue to move the tumbler about its axis to the position shown in Figure 2
against the pressure of the spring G.
It is advisable that the punching mechanism should be controlled by any of the
well known devices, so that when the punch is moved downward so as to perforate
the ticket, it is restrained from returning to the normal position until its proper
stroke has been completed, in order that the recording and signalling mechanism
may be operated with certainty, every time the punch clips a ticket.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1st. In a ticket punching and recording device, a punch having a locking device
or operative means for a locking device arranged at the end of the punch and
moved therewith, the edge of the punch being adapted to protect the locking gear
from operation except by direct pressure on the material in being partially punched,
in combination with a die.
2nd. In a ticket punching and recording device, a punch having a recess at its
end a tumbler or detent pirotted to the punch within the recess, adapted with a
projection to engage the edge of the die in the locking position, and to be moved
into the unlocked position by the ticket or other material, during the cutting of
the same, in combination with a die beneath the punch, substantially as described.
3rd. In a ticket punching and recording device, a punch having a locking device
or operative means for a locking device, carried thereby, the edge of the punch
being adapted to protect the locking gear from any influence except that produced
by the cutting of the ticket or other article.

4th. In a ticket punching and recording device, a punch with a recess, a pivotted

page_text: and spring pressed tumbler, arranged in the recess and adapted to engage with
the die in the locked position, and to be operated into the unlocked position by
contact with the ticket or other article, substantially as described.
5th. A ticket punching and recording device, constructed and arranged substan-
tially as described and illustrated in the accompanying drawings.
