I JULIUS RIEDEL of No. 14 Borsig Strasse in the City of Berlin, Prussia, Germany,
Engineer, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
ALARM APPARATUS FOR TRAMWAY AND OTHER CARS OR CARRIAGES" to be as follows:-
--
This invention relates to the construction of an alarm apparatus for tramway and
other cars or carriages according to which the signal gong or hell is connected to the
handle of the brake lever in such manner that the driver can if desired brake the car
or carriage and at the same time set the alarm apparatus in operation.
The alarm apparatus hitherto employed or proposed to be employed with tramway
and other cars or carriages possessed the great disadvantage that the alarm apparatus
could only be put in operation by employing a complicated lever mechanism which
readily gets out of order through wear and tear in the joints and this gave rise to
stoppages so that the alarm apparatus in many cases fails to act.
Now in order to avoid all disadvantages arising from such said lever or other
complicated alarm apparatus I employ the handle of the brake lever or spindle as
standard for the alarm bell or gong-The movement of the tongue or tongues is
effected by means of a muff or collar arranged around the bell standard which said
muff or collar can slide on the said standard and can act as handle for operating the
brake spindle or can be arranged in immediate connection with the same The bandle
can be arranged above or below the bell or gong and the tongue or tongues can be
operated from the said muff or collar or from a knob above the said handle by forming
their rear ends in suitable manner as will be explained in the final specification to be
filed in this matter.

Improvements in Alarm Apparatus for Tramway and other
Cars or Carriages.
I, JULIUS RIEDEL of No. 14 Borsig Strasse in the City of Berlin, Prussia Germany,
Engineer, do hereby declare the nature of my said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to the construction of an alarm apparatus for tramway and
other cars or carriages according to which the signal gong or bell is connected to the
handle of the brake lever in such manner that the driver can if desired brake the car
or carriage and at the same time set the alarm apparatus in operation. The alarm
apparatus hitherto employed or proposed to be employed with tramway and other cars
or carriages possessed the disadvantage that the alarm apparatus could only be put in
operation by employing a complicated lever mechanism or more complicated parts
which readily get out of order through wear and tear in the joints, the effects of snow,
frost and atmospherical influence in general and this gave rise to stoppages so that the
alarm apparatus in many cases fails to act and besides this complicated mechanisms
are always expensive.
Now in order to avoid all disadvantages arising from such said lever or other
complicated alarm apparatus I employ the handle of the brake lever or spindle as
standard for the alarm bell or gong. The movement of the tongue or tongues is
effected by means of a muff sleeve or collar arranged around the bell standard which
said muff or collar can slide on the said standard and can act as handle for operating
the brake spindle or can be arranged in immediate connection with the same.
According to my improved construction the bell is arranged so near the handle
that an extension of the handle or sleeve leads direct to the tongue or tongues
whereby the advantage is achieved that the centrifugal action of the increased weight
of the parts will facilitate the braking operation and besides this the entire mechanism
is arranged compactly so that the same can be readily removed from or applied to the
crank of the brake spindle by being inserted in a muff ring or socket attached to the
said brake spindle crank. The handle can be arranged above or below the bell or
gong and the tongue or tongues can be operated from the said muff or collar or from
a knob above the said handle by forming their ends in suitable manner as described
later on in this specification.
In the accompanying drawings,
Figure 1 represents a section of the bell with my improved mechanism and a part
of the brake spindle crank in elevation.
Figure 2 and 3 are like representations of modified arrangements of my improved
mechanism.
Figure 4 is a representation of the application of my improved apparatus.
My improved mechanism consists of the standard bc which fits loosely into a ring
or carrier attached to the crank a of the brake spindle. The belly is preferably

page_text: attached to the superior part of the said standard b c which according to the device
represented by Figure 1 is arranged to receive the pivots ss' on which the upper ends
of the tongues p p oscillate and with a slot to receive the connection between the
upper extension of the muff or hand piece or sleeve f. The inferior end of the said
standard b c is provided with a catch z so as to prevent the device from being
inadvertently drawn from the ring d in operating the bell or gong. f is the sleeve or
hand piece for the brake and also for the alarm apparatus and is generally made in the
form of a sleeve which can be moved up and down on the standard between the stops g
and to operate the tongues pp for which purpose the extensions of the said sleeve f
reach to the upper ends of the tongues p p and are so arranged that when the
sleeve fis moved up and down the tongue or tongues of the bell or gong will he
operated.
is a ring fixed to the standard b c which acts as stop for the sleeve fand also for
the ring d on the brake a.
In order that a stroke of the tongue may be caused at each up and each down stroke
of the sleeve f two tongues can be employed as represented in Figure 1 or as shown
in Figure 2, the same object can be attained by causing the transverse connection of
the sleeve extensions to gear between the two prongs kl at the head of the tongue p
near the fulcrums so that the said extensions of the sleeve will operate the tongue p
at each up and each down stroke.
If it is desired to operate the tongue by means of lateral pressure it is only
necessary to provide the sleeve with suitable lugs to receive a pivot n running
through or attached to the short arm or arms of a bell crank lever or bell crank
levers with the fulcrum at m whilst the superior end o of the same gears into a slot
of the bell tongue p direct or by means of a suitable stud or pivot.
Figure 4 represents as aforementioned the application of my improved device to a
tramway car or carriage.
From the foregoing it will be seen that I have shown and described the main
features of my invention so as to enable those skilled in the art to readily understand
the same, but I wish it to be understood that I do not confine myself to the special forms
of the parts as represented by the accompanying drawings or to the exact proportions
and mode of connecting the said parts as these can be varied in many ways without
departing from the nature of my said invention.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. An alarm apparatus for tramway or other cars or carriages in which the brake
spindle or the crank arm to the same is employed as support or carrier for the said
alarm apparatus whereby the bell or gong is arranged above the crank arm of the
brake spindle and a sliding sleeve on the standard of the alarm apparatus is so
connected either direct or indirect with the tongue or tongues of the bell or gong that
the said tongue or tongues are set in operation to sound the bell or gong when the
aforesaid sleeve is moved up or down on the standard substantially as described in the
foregoing specification and shown in the accompanying drawings.
2. The arrangement application and employment of a ring or carrier to the end of
the crank arm of the brake spindle so as to permit the ready application or removal
of the alarm apparatus, substantially as described in the foregoing specification and
shown in the accompanying drawings.
