Improvements in Alarm Ticket-delivery Apparatus for Tramways,
Omnibuses, and the like.
I, ERNST KNOOP, a subject of the Emperor of Russia, of No. 5 Consistorskaja in
the City of St. Petersburg, in the Russian Empire, do hereby declare the nature of
my invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to that class of controlling apparatus which cause a bell to be
struck, as soon as a ticket is drawn out and in position to be torn off from the con-
tinuous roli, so that a certain control may be exercised not only by the officials but
also by the public.
In order to make my invention more clear I refer to the accompanying drawings,
which form part of this Specification and in which similar letters denote similar parts
throughout the several views.
Fig. 1 is a sectional plan of the apparatus the supporting plate being shown partly
in section the hell and casing cut through the middle.
Fig. 2 is a side elevation seen from the direction of the arrow in Fig. 1 with the bell
and plate D removed.
Fig. 3 is an end elevation of the mechanism without the casing.
Fig. 4 is a detail view of the ratchet device for preventing the roll from being turned
backwards.
a is a rotary drum for the reception of the paper B, arranged in the casing A, the
cylinder of which drum is provided with small spikes for gripping the paper eni, in
winding the same on to the roll. A second roll 6, revolving round a pivot riveted or
in any other convenient manner affixed to the plate D, has a circumference equal to
the length of two tickets. This roll or drum has a rough surface so that the paper
on being pulled out of the casing at r, revolves the drum b. In the end of drum or
roll b (Fig. 2) are two pins cc, which as the drum revolves strike a projection d in the
boss of the bell hammer f. This hammer f is pivoted to the plate d and under the
influence of a spring m tending to retain it in the position, shown in Fig. 2. The pivot
on which the drum a revolves projects through the plate D and is formed to receive
the bell g which is screwed on to it. The hammer ef as shown in Fig. 1 also extends
through a slit ir. the plate I said slit being shown in dotted lines in Fig. 2. The
druma is allowed a small lateral play on its pivot by means of the spring to prevent
the same from being stopped by any unevenness in the breadth of the paper or manner
in which the same is wound on the drum.
The ratchet and wheel ih prevent the drum b from being turned backwards the
ratchet wheel h being fixed on the pivot of roll or drum b whilst the ratchet with its
spring revolve with the drum.
The paper B is wound on the drum a as shown in Fig. 2, then passes under and
round roll on to which it is held by a spring holder k¹, under a pressure roll a
(Fig. 2) and out of the casing at r. On pulling the end of the paper out of the
apparatus, the roll 6 will be revolved and one of its pins will strike the projection < on
the hammer boss, pressing it downwards against the influence of the spring m.
however the drum continues to revolve the pin c will run off the projection d releasing
the same when the bell will be struck and the ticket may be torn off.
As
It is obvious that I can make the drum of any size and provide it with as many
pins to actuate the bell two or more times per revolution, if so desired, without
departing from the nature of my invention.

page_text: 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 and desire to secure by Letters Patent is :-
1. In combination with the drum a arranged on its pivot with a spring as specified,
and a bell g, a hammer ef pivoted to the frame plate D and having a spring m and
projection d said hammer actuated by the pins c c in the revolving drum b, substantially
as described.
2. In combination with the drums a and b, bell and hammer ef, the casing A
having outlet r, the pressure roll & and spring holder in the manner and for the
purpose, substantially as described.
3. In combination with the drums a and b, hammer e f and bell 9, the ratchet
device, arranged on the end of the drum in the manner and for the purpose.
substantially as described.
