Complete Specification Lelt, 29th Aug., 1895-Accepted, 5th Oct., 1895
We, JOHN M NAY RIMINGTON, of 4 Picton Place, and TIMOTHY SHEPHERD,
of 17 St. Thomas Street, both in the City and County of Newcastle-upon-Tyne, do
hereby declare the nature of this invention to be as follows:-
Our invention has reference to bells and in mechanism for operating the same
and consists essentially of a dome, provided with a suitable number of protuberances,
pivotted and adapted to revolve, together with a spring hammer or its equivalent
located to come into contact with such protuberances when the dome is caused to
revolve, and means for effecting such revolution.
In carrying out our invention the revolving dome may run upon a pivot formed by
a pin in its centre having a tapered point on the inside and outside of the said dome.
A suitably shaped base-plate and bridge-piece is centred to receive the pivot of
the dome one of which centres is in an adjustable screw to regulate the distance to
the pivot points. A slotted sleeve is made to fit loosely over the central pin, its
slots engaging with a cross-pin or its equivalent carried by the first mentioned
pin thereby preventing the one revolving independently of the other but
allowing the sleeve an upward motion over the central pin. The lower end of
the slotted sleeve is formed with ratchet teeth adapted to engage with one or
more correspondingly shaped teeth or projections on the upper end of a pinion
wheel running on a short central pin in the base-plate which latter pin also serves
as the lower bearing for the dome spindle. A rocking arm, which may be shaped
into a finger piece, is pivotted to the base-plate. The opposite end of this arm is
formed into a toothed sector which engages with the pinion wheel herein before
mentioned. A spring hammer is placed on the base-plate in a position to catch the
protuberances on the dome as it revolves.
Upon operating the racking arm or finger-piece the toothed sector drives forward
the pinion wheel the ratchet teeth on the upper end of which gear with those on
the end of the sleeve, revolving such sleeve and with it the dome the pro-
tuberances of which come in contact with the spring hammer resulting in a
continuous ringing until the dome again becomes stationary. A suitable spring
effects the return of the rocking arm after use revolving the pinion wheel in the
opposite direction but producing no other result as the ratchet teeth on the pinion
wheel and sleeve respectively ride over each other.
It will be obvious that the above described bell may be applied to various uses.
For example to adapt it for use on a velocipede, a suitable clip is attached to the
Lase-plate for the purpose of fixing it to the machine. For table use it may be
fixed to an ornamental or other base and in that case we prefer having the dome
pin in a horizontal position and a light spring forcing the sliding sleeve into gear
with the pinion.
It will also be obvious that two domes may be fixed to one spindle and operated
in accordance with our invention.

We, JOHN MCNAY RIMINGTON, of 4 Picton Place, in the City and County of
Newcastle-upon-Tyne, and TIMOTHY SHEPHERD, late of 17 St. Thomas Street,
Newcastle aforesaid, but now of Kenilworth, Oakfield Road, Birmingham, in the
County of Warwick, 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 :-
Our invention has reference to bells and in mechanism for operating the same
and consists essentially of a dome provided with one or more protuberances,
pivoted and adapted to revolve, together with a springing hammer or its equivalent
located to come into contact with such protuberances when the dome is caused to
revolve, and means for effecting such revolution.
In the accompanying drawings,
Figure 1 is a central vertical section, Figure 2 is an elevation, and Figure 3
is a plan with the dome removed showing our invention applied to a velocipede
hell.
Figure 4 shows its application to a door, and
Figure 5 to a table bell.
In carrying out our invention and referring more particularly to Figures 1, 2
and 3 the revolving dome A may run upon a pivot formed by a pin or spindle a at
its centre having a tapered point a' on the inside and one a on the outside of the
said dome. A suitably shaped base-plate B and bridge-piece C is centred to
receive the pivot of the dome one of which centres is in an adjustable screw D having
a back-nut d located either at the bridge or base-plate to regulate the distance
to the pivot points. A sleeve E is made to fit loosely over the central pin or
spindle a and has slots e, e which engage with a cross-pin F carried by such
pina or other means are provided for preventing the sleeve E revolving inde-
pendently of the central pin or spindle a but permitting of lateral motion of the
one over the other. This sleeve is forced to gear with a pinion wheel G by a light
spring S. The one end of the sleeve E is forned with ratchet teeth adapted to
engage with one or more correspondingly shaped teeth or projections g on the
adjacent end of a pinion wheel G which runs on the pin D. A rocking arm K,
which may be shaped into a finger-piece as shown, is pivoted at to the base-
plate and may carry a projection A arranged to come in contact with the dome and
to act as a brake or silencer. The opposite end of the arm K is formed into
a toothed sector L which engages with the pinion wheel G. A hammer M
having a springing stem m secured to the base-plate and preferably maintained in
position between two pins p¹, p² catches the protuberances b, b on the dome as it
revolves.
Upon operating the rocking arm K the brake or silencer leaves the dome, the
toothed sector L drives forward the pinion wheel G the teeth or projections g of
which gear with those on the sleeve E evolving such sleeve and with it the
dome A the one or more protuberances of which come into contact with the
springing hammer Me-ulting in a continuous ringing until the dome of itselt
again becomes stationary or by contact with the brake or silencer k'.
spring N effects the return of the 1ocking arm after use, the pinion wheel G being
revolved in the opposite direction but producing no other result as the teeth or
projections and ride over each other.
A suitable
For
Obviously the bell such as described may be applied to various uses.
example to adapt it for use on a velocipede it may be secured thereto by one or
more suitable clips. The drawings show two spring steel clips R, the base-plate of
the bell being provided with lugs T from each of which a screwed stem U projects.

page_text: The spring steel clips R are each provided with slots at their extremities through
which the screwed stem U passes and they are clamped between the lug T and a
fly nut V. For other uses a cord or wire may be attached to the rocking arm K
and the finger piece may then be dispensed with or for door bells a hanging
pawl W as shown in Figure 4 is fixed to the rocking arm so that it will be
operated on opening the door X as indicated by the arrow.
For table use it may
be fixed to an ornamental or other base and the operating mechanism may be
similar to that herein before described or the pinion wheel, sleeve and rocking
arm may be dispensed with as shown in Figure 5 by placing a knob t upon
the top of the dome after passing its central pin through the bridge which in
this and other cases can be made on the inside instead of the outside of the
dome.
Obviously also two or more domes may be fixed to one spindle and operated in
accordance with our invention and the pin or spindle may be vertical as shown in
Figure 1 or horizontal as indicated in Figure 4.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim 18:
1. A bell comprising a dome, provided with protuberances b, pivoted and
adapted to revolve about, and come in contact with, a springing hammer M
and means for effecting the revolution of such dome.
2. In a bell, the combination with a pivoted dome having one or more pro-
tuberances and a springing hammer M, of operating mechanism comprising a
toothed sector L a pinion wheel G and a sliding sleeve E substantially as set
forth.
