IMPROVEMENTS IN CALL AND OTHER BELLS
Year: 1885

page_text: I JAMES HENRY STONE trading as Benton & Stone of St Paul's Square
Birmingham in the County of Warwick Manufacturer, do hereby declare the
nature of my said Invention for "IMPROVEMENTS IN CALL AND OTHER BELLS
33 to
be as follows:-
The object of this invention is a simple arrangement of mechanism applied to
call or other bells whereby it becomes possible to give a succession of blows to the
bell clapper and thus to obtain a continuous ringing or sounding of the bell similar
to an electric bell, without the intervention of springs and consists in mounting
the clapper or hammer upon a pivot by means of a loose joint, so that as such
pivot revolves the clapper is free to strike the bell by centrifugal force at each
revolution of the pivot and then to pass by and fly outwards again ready to strike
the bell once more and so on continuously.
In this manner I secure a clear ring of the bell for each blow of the clapper and
I obtain the requisite continuous ringing action as aforesaid by gearing the said
pivot say for instance by a train of wheel work or by means of an endless band
passing over grooved pulleys to a spindle, which spindle is capable of being revolved
in either direction by a knob or button secured at one extremity or revolved in
any other convenient manner.

page_text: I JAMES HENRY STONE trading as Benton & Stone of St Pauls Square,
Birmingham in the County of Warwick, Manufacturers, 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 this invention is a simple arrangement of mechanism applied to
call or other bells whereby it becomes possible to give a succession of blows to the
bell clapper and thus to obtain a continuous ringing or sounding of the bell similar
to an electric bell without the intervention of springs and consists in mounting the
clapper or hammer upon a pivot by means of a loose joint, so that as such pivot
revolves the clapper is free to strike the bell by centrifugal force at each revolution
of the pivot and then to pass by and fly outwards again ready to strike the bell
and so on continuously.
In this manner I secure a clear ring of the bell for each blow of the clapper and
I obtain the requisite continuous ringing action as aforesaid by gearing the said
pivot say for instance by a train of wheel work or by means of an endless band
passing over grooved pulleys to a spindle which spindle is capable of being revolved
in either direction by a knob or button secured at one extremity or revolved in
any other convenient manner.
And in order that this my said invention may be the more readily understood
and carried into practical effect I have hereunto annexed a drawing of one
arrangement of my invention applied to a Call Bell but it should be observed that
the improvements are equally applicable to sounding other bells in a similarly
continuous manner.
Fig. 1 is a side view and Fig. 2 a front view or plan (both partially in section)
of a Call Bell embracing my improvements.
A is the base or stand and B the gong or bell-this latter being supported upon
the hollow stud C rising from the frame D This frame carries a train of wheel-
work consisting of a toothed wheel E affixed upon the central spindle F and' to the
outer extremity of which the actuating knob or button G is also affixed. The
wheel E gears with a pinion H upon an intermediate spindle I which also carries a
toothed wheel I¹ gearing in its turn with a pinion J upon the clapper spindle K.
The clapper L is mounted loosely upon a pivot M affixed in the face of the disc N
carried by the same clapper spindle K and as seen more clearly by a separate front
view in Fig. 2.
It will thus be apparent that the wheel-work is so geared up to give an
accellerated speed to the clapper spindle and that by giving a partial revolution
to the actuating knob or button G a series of complete revolutions are imparted to
the clapper spindle. It will be further apparent that being mounted loose as
aforesaid the clapper L is free to strike the bell B by centrifugal force at each
revolution of the clapper spindle and then to pass by and fly outwards again ready
to strike the bell once more and so on continuously.

page_text: Instead of employing toothed wheel-work it will be obvious that the revolution
of the clapper spindle could be effected by grooved pulleys and endless bands and
that there are many other mechanical equivalents for imparting the necessary
revolutions to the clapper spindle when so mounted as aforesaid.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
Mounting the clapper of call and other bells upon a spindle capable of being
revolved and whereby a succession of blows are imparted to the bell substantially
as and for the purposes herein before described.
