Improvements in and relating to Bells for Tables, Bicycles, and
Burglar Alarms.
I, WILLIAM ODDY, Mansfield Estate, Ringwood Hampshire, Window Blind
Manufacturer, 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:-
This invention relates to bells for tables, bicycle and burglar alarms & consists in
the improved construction and arrangement of same and is carried out in the
following manner reference being had to the annexed drawings in which,
Figure 1. is a side elevation of my invention part of the casing being removed
for purposes of clearness.
Figure 2. plan view of same.
Figure 3. view of arrangement of clips attached to window frame when bell is
employed as a burglar alarm.
Figure 4. view of clips on bell.
Figure 5. view of bell on a stand when used as a table bell.
Figure 6. view of bracket attached to bell when used as a bicycle bell.
Referring to figure a is the hammer which is carried upon the spindle b, this
spindle having bearings in the side plates b, d is a palate or escapement piece
attached to the spindle b, and engaging with the toothed escapement wheel e carriei
upon the spindle f, which has bearings in the side plates b'. This spindle is
driven by a small toothed wheel g, which engages with the larger toothed wheel /
through the medium of spur wheels 1 & 2. This wheel is connected to one enl
of a coil spring i (Fig. 2). The other end of this coil spring i is connected to the
spindle and controlled by a pawl 1, engaging with the ratchet wheel K fixed to
the spindle (Fig. 2) & controlled by the spring m (Fig. 1). The wheel is free to
revolve on the spindle j when acted upon by the spring. n is a suitable thumb piece
or key for rotating the spindle; when winding up the spring i. o is the bell which
is carried by the rod p secured to the top of the casing as shown in Figures 1 & 2.
9 is a flat spring secured to the casing at (Fig. 1), to this flat spring q is connected
a rod or push piece, which terminates outside the casing in a knob or handle.
This flat spring controlls the action or movement of the small lever s attached to
the spindle b. It will be seen that when the spring i is wound up, & the lever or
push piece t moved in the direction of the arrow 1, the palate d is free to vibrate
owing to the levers being released by the spring 9 being removed from contact
with same & thus the bell is rung by the hammer a as long as the spring q is
removed from the lever s.
Referring to Figure 3. 3. & 4. are two socket pieces attached to the side of the
window frame in which two clips 5. & 6. (Fig. 4) attached to the casing 1 of the
bell engage, the spring 7 retaining said clips in engagement in the sockets.
8 is a spring attached to the window sash 12. It will be seen that when the
window sash is raised, or lowered according to the arrangement thereof the spring 8
comes into contact with the push piece t & by moving same causes the bell to
be rung.
Referring to Figure 5. In this case the stand 9 is provided with a similar set of
sockets as described in Figure 3 so that the casing & bell may be attached thereto
& used as a table bell when desired.
Referring to Figure 6. In this case the bracket 10. is secured to the casing.
The bell may then be readily attached to the bicycle or like machine by any of
the well known means, such as a spring clip etc.
It will thus be seen that by the above arrangement the bell may be used as a

page_text: bicycle or table bell & also as a burglar alarm as desired, being attached to the
window or table stand by the clips as shown.
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. The improved door bell, in combination, a push piece attached to a spring a
small lever engaging with said spring and carried by a spindle, a hammer attached
to said spindle, a palate piece engaging with an escapement wheel attached to said
spindle; a train of wheels, a coil spring operating said train of wheels, a spindle
terminating in a key or thumb piece for winding said coil spring, a bell struck by
said hammer, a casing enclosing said mechanism and supporting the bell, said
casing being attached to the window frame or other suitable place by means of clips
and sockets, a controlling spring and a bent spring attached to the window sash,
said bent spring engaging with the push piece, when the sash is raised or lowered,
substantially as described.
