IMPROVEMENTS IN ELECTRIC BELLS AND MOTORS
Year: 1884

page_text: I JOHN CHARLES BAYLEY of Parkstone near Poole in the County of Dorset
Ironmonger do hereby declare the nature of my invention for IMPROVEMENTS IN
ELECTRIC BELLS AND MOTORS to be as follows:-
My invention relates to a method of obtaining continuous rotary motion from
a vibrating armature which is exemplified in the accompanying drawing, an
armature a, caused to vibrate by an electromagnet f, is connected by a rod e to a
soft iron disc d which is mounted loosely on the spindle c On this spindle is
rigidly fixed an Electro-Magnet b, connected in series with the Electro-Magnet f.
The action is as follows:-When the Electromagnets b, f, are excited, the disc-
armature d is held tightly by the magnet b. The armature a being attracted by
the magnet causes the spindle c to turn through a small angle, on the circuit being
broken at g, d is released and a falls back to its original position. Thus c is caused
to rotate continuously in the same direction. The motion thus obtained may be
used to ring a bell, or for other purposes.

I JOHN CHARLES BAYLEY of Parkstone near Poole in the County of Dorset
Ironmonger do hereby declare the nature of my invention for IMPROVEMENTS IN
ELECTRIC BELLS AND MOTORS 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 electric bells and motors and consists of means whereby
vibrating or reciprocating motion is transformed by means of a sort of electric
clutch as hereinafter described into rotary motion in one direction. To a shaft or
spindle I rigidly fix an electro-magnet (one or more) and on the same spindle
I loosely mount a soft iron disc which just touches the poles of the electro magnet
and forms an armature thereto. To this disc I connect excentrically a rod or bar
which receives vibrating or reciprocating motion from the armature of another
electro magnet connected in series with the first described electro magnet. In
connection with the rod or bar is a contact maker and breaker by which when the
rod and disc move in the one direction contact is made with a battery or source of
electricity so that the disc being held to its electro magnet the electro magnet
moves with it through a small angle; when on the other hand the rod and disc
move in the other direction the contact is broken and the disc is no longer held to
its electro magnet which therefore does not move with it. These actions being
repeated at every to and fro movement of the rod and disc the electro magnet and
its spindle continue to rotate in the same direction and the continuous rotary
motion thus obtained is utilized to ring a bell or as a motor.
Figure 1 of the accompanying drawings is an elevation and Figure 2 a plan
illustrating my invention applied to an electric bell.
a is the armature of an electro magnet b, and is arranged in the usual manner
for electric bells, h being the contact spring and g the contact screw. c is a light
rod or bar attached at one end to the armature a and at the other end loosely to a
soft iron disc d. fis an electro magnet on which the disc d rests, and which is
rigidly fixed to the spindle e. At one end of the spindle e is an insulated cylinder u
to which one end of the wire on the electro magnet fis attached and which makes
contact with the battery by means of the spring j. The two electro magnets b
and fare connected in series and the connections are so arranged that contact is
made or broken for both electro magnets at the same time by the spring h. When
the current passes, the electro magnet b attracts the armature a and thus, by
pushing the rod c, moves the disc d forward through a small angle and as the electro
magnet fis also magnetized it is held to d and is moved with it together with the
spindle e. The circuits being now broken at g the electro magnets b and fare no
longer magnetized and the armature a returns to its first position drawing with it
the bar c and the disc d. But as the electro magnet f is no longer magnetized it is
not drawn with the disc but continues to revolve by virtue of the momentum
already gained. When the armature a has returned to its original position contact
is again made and the actions just described are repeated and so on continuously
by the successive makings and breakings of the contact at g.
On the spindle e is a cam i which at every revolution acts on the spring arm of
the hammer k of the bell l.
If instead of ringing a bell it is required to actuate mechanism for any other
purposes the rotary motion of the spindle or shaft e can be taken off by any
suitable gearing.

page_text: It is evident that instead of the electro magnet b and its armature a any other
suitable apparatus connected in series with the electro magnet f can be employed
to impart vibrating motion to the disc d, such for example, as a solenoid whose
core would move the disc d or a rotary electric motor fitted with an excentric or
cam to move the disc.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In electric bells and electric motors an electro-magnet mounted rigidly on a
spindle or shaft, and having an armature not rigidly fixed on the spindle, the said
armature receiving a reciprocating movement from a vibrating rod or bar, this
movement owing to the alternate magnetization and demagnetization of the said
electro magnet being in the one direction with, and in the other direction without,
the said electro-magnet and spindle which therefore receive a continuous rotary
motion in one direction substantially as herein before described.
2. In electric bells and electric motors the imparting of a continuous rotary
motion to an electro-magnet and its spindle substantially as hereinbefore described
from a vibrating motion derived from another electro-magnet or equivalent apparatus
connected in series with the first named electro magnet as set forth.
3. Constructing electric bells and electric motors as herein before described.
