PROVISIONAL SPECIFICATION.
Improvements in Bell-sounding Apparatus.
I, GEORGE WILLIAM EVERY, of 102, Barnsbury Road, Islington, in the County
of London, Clock Manufacturer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to apparatus for obtaining sounds resembling the tone of
such bells as are used in cathedrals, large clocks and other places.
According to my invention I employ bars or rods of any suitable material such
as steel and of any suitable section. These bars I hang in a row or rows in such
manner that they may be struck by hammers or other striking mechanism. By
lengthening weighting or altering the diameter of the bars any tone or note may
be obtained.
A convenient way of suspending the bars in my improved bell sounding apparatus
is as follows:-
Round the upper extremity of the bar I place a collar having two or more lugs
thereon. This collar is shrunk or otherwise fastened preferably at one of the
nodal points of the rod. To each of the lugs I fasten a cord preferably of
non-conducting material the other end of which cord passes over a hook on the
framework or is fastened to the framework in any other convenient way.
In some cases I provide means to regulate the swinging of the bars when struck
by the hammer, as on the haminer coming down a second time the bar might be
at too great a distance to be struck by the said hammer. This would also prevent
the necessity of removing the bars when moving a clock fitted with apparatus
constructed according to my invention.
Apparatus constructed according to my invention may be used in all cases where
chimes of bells are now employed and clock sounding mechanism generally.

COMPLETE SPECIFICATION.
Improvements in Bell-sounding Apparatus.
I, GEORGE WILLIAM EVERY, of 102, Barnsbury Road, Islington, in the County
of London, Clock 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 :-
.
My invention relates to apparatus for obtaining sounds resembling the tone of
such bells as are used in cathedrals, large clocks, and other places.
According to my invention I employ bars or rods of any suitable material such
as steel and of any suitable section. These bars I hang in a row or rows in such
manner that they may be struck by hammers or other striking mechanism. By
lengthening weighting or altering the diameter of the bars any tone or note may be
obtained.
The bars may be suspended in various ways such as by placing a collar having
two lugs thereon shrunk or otherwise fastened to the bar at one of its nodal points
and suspended by non-conducting material from the lugs. I have also found after
careful experiments that by drilling a hole through the bars at their upper nodal
points and threading a cord of non-conducting material through same by which
LD

page_text: cord they are suspended I obtain bars which vibrate with almost perfect freedom
and chimes may be rung thereon or music played by suitable mechanism.
In order that my invention may be better understood and easily carried into
effect I will proceed to further describe same with reference to the accompanying
drawings.
Figure 1 is a front view of the upper part of my bar bell sounding apparatus
showing the way they are or may be conveniently suspended and having striking
mechanism attached.
Figure 2 is a side sectional view of the mechanism shown in Figure 1 and
Figure 3 is a view of my bar bells suspended in a frame and from which view
the approximate proportions may be seen.
Similar letters of reference refer to like parts in all the figures.
A are the bar bells which are shown suspended by cords B to the hooks C on
the cross bar D. The hole B' is drilled at the nodal point of the bar through
which the cord B is passed as shown. E are the striking hammers which are
actuated by the pins on barrel F and spring G. My striking mechanism as
shown in Figures 1 and 2 I have found very effective in bringing out the full tone
of the bells and it does not get out of order as do most striking mechanisms at
present in use; besides I am able to supply these striking mechanisms at a com-
paratively, very low cost as compared with those heretofore employed.
In some cases I provide means to regulate the swinging of the bars when struck
by the hammer, as on the hammer coming down a second time the bar might be at
too great a distance to be struck by the said hammer. This would also prevent the
necessity of removing the bars when moving a clock fitted with apparatus constructed
according to my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
:-
First. In bell sounding apparatus, suspending a bar of suitable material from its
upper nodal point, by a connection of non-conducting material in such a manner
that it is free to vibrate on being struck by a hammer substantially as described
and illustrated with reference to the accompanying drawings.
Second. In bell sounding apparatus the combination of the bars A formed with
holes B', the cord B, hook C, and cross bar D, together with suitable striking
mechanism substantially as described and illustrated with reference to the accom-
panying drawings.
Third. The bar bells A. so suspended and arranged that chimes may be rung
thereon or music played substantially as set forth.
