Improvements relating to Alarm Bells for Velocipedes.
I, LUCIEN STEPHEN CRANDALL, of the Village of Parish, County of Oswego, and
State of New York, United States of America, Gentleman, 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 :-
My invention relates to the application of an electric alarm bell and actuating
apparatus to bicycles and other velocipedes, whereby I am enabled to arrange the
parts neatly and in a manner by which I may effect their ready withdrawal for the
renewal of the cell or repairs of parts or connections as occasion may require.
My invention consists in arranging the battery and actuating solenoid within the
steering tube and the super-position of the bell upon the handle bar in alignment
therewith.
In the accompanying drawings which illustrate the application of my invention,
Figure 1 is a sectional elevation showing the arrangement of bell and actuating
apparatus within a cycle steering tube.
Figure 2 is a plan thereof with the bell removed.
Figure 3 is a section on a y Figure 1, while
Figure 4 is a plan of the handle bar on a reduced scale.
In carrying my invention into effect as illustrated in the drawings I provide a frame
or cradle A of semi-circular section having a complete annular flange a at its upper
end which serves to hold the cradle within the tube on introduction therein. The
cradle is provided with a base support a' upon which rests a dry battory B, such being
held in position by spring clipping arms a provided upon the cradle, so that the cell
is firmly secured in position upon the cradle though capable of ready removal when
required. A solenoid C is super-posed above the cell and is suitably secured to the
cradle; the extremity of the soft iron core E of the solenoid C projects above the
level of the flange of the cradle and an armature piece F is disposed immediately
above and is secured upon a spring-striking lever G, the extremity of which is
provided upon a bracket D which is in turn secured upon an extension of the cradle
flange.
The bell is secured upon a bridge piece H provided upon the handle bar which is
secured upon either side or to the flange of the cradle, and supports the bell I from a
pin or pillar f. The connections and wires are properly insulated and a contact.
button J is provided upon the handle K in a suitable position for actuation by the
thumb or fore-finger.
A contact button may be arranged with wire connections upon each handle.
Upon contact being made the current passes through and the core of the magnet is.
energised and the armature piece is attracted, thereby instantly breaking connection
and de-energising the core, thus allowing the striking lever to retreat under influence.
of its elasticity. Contact is thereupon again made and so the striking lever is rapidly.
vibrated in the usual way.
I do not confine myself to the actual disposition of the cell, solenoid, connections or
operating parts as indicated in the drawings, as I may for instance provide the cell
and solenoid within the handle bar upon opposite sides of the steering tube, in which
case I provide the striking lever vertically disposed, or I may provide the cell within
the handle bar and the armature and spring striking lever disposed as indicated in the.
drawings.

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 is :-
(1.) In velocipedes, the provision of an electric alarm bell with battery, solenoid
and operating parts substantially as herein before described.
(2.) In velocipedes, the provision of an electric alarm bell, with battery, solenoid
and operating parts, the solenoid being arranged within the steering tube and having
its core protruding, the vibrating lever being super-posed, and the bell arranged upon
the handle,bar in alignment with the axis of the steering tube substantially as
described.
(3.). In velocipedes, the provision of an electric alarm bell with battery, solenoid
and operating parts secured together or upon a cradle or frame of suitable form. to
correspond with the interior diameter of the steering tube into which the frame is
placed, the solenoid being super-posed upon the battery, the vibrating lever being
arranged above the solenoid and the bell being secured upon the handle bar in
alignment with the steering tube substantially as described.
(4.) In velocipedes, the provision of an electric alarm bell with battery, solenoid,
and operating parts arranged substantially as described with reference to the
Figures 1, 2 and 3 of the drawings.
