I THOMAS JOHN WHITING of 7 South Place Finsbury London, E.C., Printer do
hereby declare the nature of this invention and in what manner the same is to be
performed in and by the following statement:
My invention relates to an improved construction of boxes or receptacle for con-
taining a roll of a continuous band of paper tickets, which is drawn out and torn off
by the conductor as the tickets are required. In such boxes as at present constructed,
the band of tickets can, after having been drawn out through the slit, he pushed back
again into the box, and by this means a fraudulent removal of part of the roll of
tickets can be effected without immediate detection. My invention has for its object
to prevent the possibility of such fraud, and it consists in providing means within the
box whereby, when a length of the continuous band has been drawn out through the
slit, it is prevented from being pushed back again. Various arrangements may be
employed for carrying my invention into effect: Figure 1 of the accompanying
drawing shews a perspective view of a ticket box with the simplest arrangement,
which prefer to employ applied thereto.
The box A has a cavity B formed at the side of the slit through which the band
issues and in this cavity is fixed a pin C in such a position that the paper band D has
to bend sharply round it on its passage from the roll to the issuing slit E. This pin
will allow the ticket band to be drawn out with a certain amount of friction, but it
will effectually prevent the band from being pushed back again in the contrary
direction.
Fig. 2 shews another arrangement in which a latch G is pressed against the pin C
by a spring, the latch being drawn away from the pin by the outward pull on the
band, so as to let this pass freely, but being made to nip the band when this is not
pulled. Fig. 3 shows a similar arrangement with two spring latches H. H and Fig. 4
shews an arrangement with two rollers 1 I covered with elastic material, that are made
to nip the band passing through between them sufficiently to prevent it from being
pushed hack

page_text: In order to provide against the box being opened by unauthorised persons who
might tamper with the roll of tickets, 1 make the hinged lid F with a latch H' which,
on closing the lid, is engaged by a spring catch K as shewn in section in Fig. 1 and
in plan in Fig. 1, so that the lid cannot be opened without withdrawing the spring
catch K. This is done by inserting a pin through a hole & in the lid F, and the pin
bearing against the inclined side of the catch K pushes it back releasing the latch H
and permitting the lid to be opened.
In order however that any such opening of the box may be detected, there is placed
in a cavity under the lid before it is closed down, a small disc (indicated by the dotted
line L Fig. 1) of penetrable material such as paper, card, wood shaving or the like,
which may be coloured or marked in any way to give identification. As this disc lies
immediately under the hole of the lid, when a pin is inserted to disengage the
latch H', the disc is penetrated by the pin, and consequently the official, whose business
it is to open the box, can know by the penetration or absence of the disc which he had
placed under the lid that the box had been opened.
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,
1. In a roll ticket box, means whereby the ticket band is prevented from being
pushed back into the box after it has been pulled out, substantially as herein
described.
2. In a roll ticket box a pin C situated in a recess in the box and so arranged that
the ticket band has to bend sharply round it before passing out through the slit,
substantially as and for the purposes herein described.
3. In combination with a roll ticket box and its lid, a latch, spring catch, and pin
with a disc of penetrable material guarding the hole by which the pin is inserted to
release the latch, substantially as and for the purpose set forth.
Dated this 5th day of September 1888.
