PROVISIONAL SPECIFICATION.
Improvements in the Mounting or Hanging of Tower, Turret, and
such like Bells.
I, WILLIAM LEWIS BAKER, A.M.I.C.E. of 22 Hillier Road, Wandsworth
Common in the County of Surrey, Architect do hereby declare the nature of this
invention to be as follows:-
In order to provide for the efficiency of bells mounted or hung on a stock or
beam and intended to be moved or turned round their vertical centre line for
the purpose of changing the positions of the parts or places on the sound bow
worn by the strokes of the clapper or by those of a clock hammer, I carry and
transfer to the stock or beam the weight of the bell and the stresses caused by
ringing, partly by means of a suspension cradle or sling fitted round a boss upon
the crown of the bell this hoss being formed and adapted to receive the said
cradle or sling; and partly by a central suspension bolt or bar the lower or tail
end of which is formed as a hinged joint for the clapper, and in order that the
latter shall always swing upon this joint in its proper plane I form a part of the
central bolt square or angular in section which part I pass through a corresponding
hole in a metal socket piece firmly fitted into the stock or beam and thus insure
that the said bolt shall not turn round in that member but so that the bell may be
moved freely round upon the collar of the central bolt when all the suspension
bolts and fittings have been slackened for that purpose; and further in the case of
large bells which from their weight would require more energy to move or turn
them round their vertical centre line I provide a joint of anti-friction balls between
the under side of the crown of the bell and the upper side of the collar of the
central suspension bolt or bar.

1, WILLIAM LEWIS BAKER, A.M.I.C.E. of 22 Hillier Road, Wandsworth
Common in the County of Surrey, Architect 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 :-
In order to provide for the efficiency of bells mounted or hung on a stock or
beam aud intended to be moved or turned round their vertical centre line for the
purpose of changing the positions of the parts or places on the sound bow worn
by the strokes of the clapper or by those of a clock hammer, I carry and transfer
to the stock or beam the weight of the bell and the stresses caused by ringing,
partly by means of a suspension cradle or sling fitted round a boss upon the
crown of the bell, this boss being formed and adapted to receive the said cradle or
sling, and partly by a central suspension bolt or bar, the lower or tail end of
which is formed as a hinged joint for the clapper, and in order that the latter shall

page_text: always swing upon this joint in its proper plane I form a part of the central bolt
square or angular in section which part I pass through a corresponding hole in a
metal socket or piece-firmly fitted into the stock or beam and thus insuring that
the said bolt shall not turn round in that member but so that the bell may be
moved freely round upon the collar of the central bolt when all the suspension
bolts and fittings have been slackened for that purpose; and further in the case of
large bells which from their weight would require more energy to turn them round*
their vertical centre line I provide a joint of anti-friction balls between the under
side of the crown of the bell and the upper side of the collar of the central
suspension bolt or bar.
An adaptation of the improvements to a bell hung on a timber stock or beam
is illustrated by Figs. 1, 2, 3 and 4 of the accompanying four sheets of drawings.
The suspension cradle or sling a, is shown in section in Fig. 1, in plan in Fig. 2,
and in elevation in Fig. 3; it is formed of two segments united by bolts b, b, Figs. 2,
and 3, so as to be an easy fit round a central boss c, cast on the crown of the
bell and so as to take a bearing against the under side of the circular flange ex, cast
upon the central boss; the bell is firmly secured to the stock or beam e, by two
double ended stirrup bolts, f, two eye bolts g, g, central in the width of the
stock and carried up through it, and with one central bolt h, all these being
furnished with plates and nuts on the top of the stock; each stirrup bolt f, f
passes under a hook or lug k, Figs. 2 and 4 formed on the cradle or sling, and
each of the two intermediate bolts g, g, is formed with an eye at its lower end
through which one of the cradle connecting bolts b, b, Figs. 2 and 3 passes; the
central bolt, passes through the central boss and the stock and under the crown
of the bell is formed with a collar 1, and is then continued downwards and
terminated with a joint n, to carry the clapper; the bolt h, has also a part h*,
formed square in section which part is passed through a corresponding hole in a
metal socket or bush m, firmly fitted into the stock or beam so that the clapper
joint n, shall always act and the clapper swing in the direction as regards the
stock indicated by the dotted arc Fig. 1. An adaptation of the improvements to
a bell hung upon a metal stock or beam is illustrated by Figs. 5, 6, 7 and 8 of the
drawings; the cradle or sling is formed by two separate bars or pieces a, a,
straight by preference shown in section in Fig. 5, in plan in Fig. 6, and in elevation
in Fig. 7; the inner side of each of these impinges on the body of a central boss c,
cast on the crown of the bell, and a part of the upper side of each takes a
segmental bearing on the underside of a circular flange c* which forms a part of
the central boss as shown at * on Fig. 6; the bell is firmly secured to the stock
or beam e, by four bolts f, f,f,t, and by the central bolt h, which passes through
the crown of the bell and the stock, is formed with a collar l, under the crown
and is then continued downwards and terminated with a joint n, for the clapper ;
the central bolt has also a part * formed square in section, which part is passed
through a corresponding hole in the bottom table or flange of the stock so that
the clapper joint n, shall always act and the clapper swing in the direction as
regards the stock indicated by the dotted are in Fig. 5.
Referring to each of the examples given :-In order to freely move the bell
round its vertical centre line for the purpose of presenting any places or parts in
the circumference of the sound bow to the wear occasioned by the blows of the
clapper, I first slaken all the suspension bolts by their nuts, but the central bolt
to a less extent than the others so that the whole weight of the hell may be
temporaly carried by the collar 1, of that bolt see Figs. 1 and 5, and then the hell
may be easily moved round on that collar as may be required.
The modification Fig. 9, applicable more especially to heavy bells shows a part
of the central bolt in section and the joint or fitting between the bell and the
collar l, formed with anti-friction balls interposed for the purpose of reducing the
amount of friction which would be set up by an ordinary collar when it may bo
desired to move the bell round its vertical centre line for the purpose herein before
described.

page_text: My said improvements apply to bells hung upon any form of stock beam or
girder formed or constructed either of wood, metal or of both.

on the
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 :-
:―
1. The provision as hereinbefore described of a cradle or sling as a part of the
fittings in the mounting or hanging of tower, turret and such like bells in order
that a bell so mounted or hung may be readily placed in a condition admitting of
its being easily moved round its vertical centre line for the purpose of occasionly
changing the position on the sound bow of the blows of the clapper.
2. And in order to further facilitate and expedite that purpose, the further
provision of a joint of anti-friction balls interposed between the bell and a collar
on a central suspending bolt.
