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 an improved arrangement of door bells as follows.
In order that my invention may be fully understood I will now refer to the
annexed drawings.

escapement wheel carried upon the spindle, which has bearings in the
casing c. This spindle is driven by a small toothed wheely, which engages
with the larger toothed wheel h. This wheel his connected to one and of a
coil spring i
The other end of this coiled spring i is connected to the
spindle and controlled by a pawl I, engaging with the ratchet wheel / Oxed to
the spindle j, & controlled by the spring m (Figure 3). The wheel is free to
revolve on the spindle when acted upon by the spring. n is a suitable thunb

Figures 2 & 3. 7 is a flat spring secured to the casing at r, the top of this spring is
bent over so as to act upon the small rod or lever attached to the spindle b. is
a push piece which passes through the door and casing cand is attached to the flat
spring 7. The action is as follows:-When the coil spring i has been wound up by
the spindle j, upon pressing the push piece the bent ead of the fat spring qʻwill
take up the position shown by the dotted lines in Figure 2 thua freeing the small

of the palate escapement piece d and toothed escapement wheel c. Upon roleasing
the push piece the flat spring q will return to its initial position and the bent end
of same will arrest the motion of the small rod or lovers and stop the mechanism.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed 1 declare that what
I claim is :-
1. The improved door bell, in combination a push piece attached to a spring
baving a bent ond, a small lever engaging with the bent end of dat spring and
carried by a spindle, a hammer attached to said spindle, a palace pieco cugaging
with an escapemont 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 substantially as described.

Referring to Figure 1a is the hammer which is carried upon the spindle b,
this spindle having bearings in the sides of the casing c. d is a palate or
escapement piece attached to the spindle and engaging with the toothed
escapement wheel e carried upon the spindle, which has bearings in the

with the larger toothed wheel h. This wheel is connected to one end of a
coil spring i The other end of this coiled spring is connected to the
spindle aud controlled by a pawl 1, engaging with the ratchet wheel k fixed to
the spindle, & controlled by the spring m (Figure 3). The wheel is free to
revolve on the spindle 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 2 & 3. is a flat spring secured to the casing at ?, the top of this spring is
bent over so as to act upon the small rod or lever s attached to the spindle b. is
a push piece which passes through the door u and casing cand is attached to the flat
spring . The action is as follows: When the coil spring i has been wound up by
the spindle j, upon pressing the push piece the bent end of the flat spring will
take up the position shown by the dotted lines in Figure 2 thus freeing the small

rod or levers and allowing the hammer a to vibrate to and fro through the action
of the palate escapement piece d and toothed escapement wheel e. Upon releasing
the push piece t the flat spring will return to its initial position and the bent end
