JOHN REUBEN TOZELAND, Engineer 110 Lefevre Road, North Bow, E. HUBERT
FREDERICK TOZELAND, Electrician 110 Lefevre Road North Bow, E. do hereby declare
the nature of this invention to be as follows:-―
The object of our Invention is to provide an electric alarm which can be set to ring
at any required time and continue to ring until stopped.
The apparatus is enclosed in a wooden box with a lid and handle at top so as to be
easily carried.
.
At the bottom of box is fixed two "Le Clanche " Batteries which ring the
electric bell fixed over the batteries. Up one side of the box is fixed a rod hereafter
called the time rod which is divided into spaces representing hours, half hours &
quarters starting at the bottom with 0 and numbering upwards, at the back of this
time rod and at the top of box is an ordinary pendulum clock work arrangement with
a drum attached to the winding axle, the drum has connected to it by a string or other
suitable material a weight which slides up and down at the back of time rod, the weight
has a small hand attached to same which points to the hours on time rod and is used
in setting the alarm.
To set the apparatus say to go off in 4 hours, wind the weight up on the drum until
the hand points to the figure 4 on time rod, the clockwork is then set in action by
touching pendulum which gradually lowers the weight to the bottom of rod. When
the weight has reached the figure 0 on rod it touches a cranked lever which releases a
hinged lever weight and allows it to fall on to a wedge shaped connection between the
batteries and bell, immediately setting the latter in motion, the bell can be stopped
from the outside of box by means of a lever which throws the hinged weight off
connection.

FREDERICK TOZELAND, Electrician 110 Lefevre Road North Bow, E. 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 our Invention is to provide an electric call alarm which can be set to
ring at any required time and which will continue to ring until stopped and our
Invention consists of the arrangement of the several parts in a box so as to be easily
removable.
To clearly explain our Invention we have prepared the accompanying drawings-
Fig. 1 shews an elevation of our "Portable Electric Call Alarm" looking towards the
front and shewing the arrangement of the several parts in the Box-Figure 2 shews
a section through Box &c. The same letters of reference indicate the same parts
in the two figures.
A is the box enclosing apparatus which has a glass door in front shewn at A¹ in
figure 2-B are the works of an ordinary pendulum clock. C is a drum fixed to the
winding axle of the clock and has a handle D attached to same for winding up clock,
this drum C has a grooved edge as shewn by dotted lines on which winds a cord
or string E, attached to the end of string E is a weight F having a small hand G
which points to the hours on the time rod H. The time rod H is divided into eleven
spaces, each space representing one hour, each hour is again divided into four parts
representing quarters-J is a cranked lever working on a pin at K-L is a guide to
prevent the lever J from falling over towards right hand side of box. M is an hinged
lever weight working on a pin at N-00 are Le Clanche batteries which ring the
electric bell P. R is a switch which completes the current to set the bell in motion-
S.S.S are the electric wires thro' which the currents pass to connect the several parts
of the apparatus together.
"
Having described the several parts of our Invention we will now describe the action
of our
"Alarm"-The "Aların can be set to go off at any time required during
eleven hours. We will take for an example that it is required to ring in six hours
from the time of setting the apparatus. Wind up the string by the handle D on to
the drum C until the hand G points to the figure 6 on time rod H as shewn on
drawing Adjust the cranked lever J and the lever weight M as shewn on the drawing
(Figure 1) Set the clock work in motion by touching pendulum and in six hours
time the weight F will have lowered to the bottom of time rod H touching the cranked
lever J at J¹ and lifting same in the direction shown by arrows on Figure 1 at the

page_text: same time releasing the lever weight M which falls on the switch R and sets the electric
bell in motion, the bell will continue to ring until the weight M is lifted off switch.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is :-
The combination & arrangement of the several parts of our "Portable Electric Call
Alarm" namely, the time rod, Clock, Batteries, Bell & Levers enclosed in a box
substantially as shewn on the accompanying drawing & described in the accompanying
Specification.
