PROVISIONAL SPECIFICATION.
Improvements in Tubular Bells.
We, THOMAS LATHAM of Fleet Works Coventry in the County of Warwick
and JOHN HARRINGTON of 14 West Kensington Gardens in the County of
Middlesex Manufacturers do hereby declare the nature of this invention to be as
follows :-
Heretofore tubular bells have been closed at one or both ends by a plug or cap,
which acted to communicate the vibration more quickly and completely from the one
side to the other. This mode of construction however had the disadvantage that
the tube was sometimes injured in driving in a plug, whilst a screw plug or cap
required very exact fitting to prevent chattering between it and the tube.
Now, according to the present invention we are enabled to obtain all the advan-
tages of a plug or cap combined with simplicity and cheapness of construction, by
the use of a cross bolt or plug.
In carrying the invention into effect we form near one or both ends of a
tubular bell, a hole in each side thereof, such holes being diametrically opposite
to each other and of such a size as to receive a hollow or solid cross plug or bolt,
which is brazed soldered or otherwise fixed in position to ensure its solidity with
the tubular bell.
The cross plug or bolt may be of copper, brass or other suitable material.

COMPLETE SPECIFICATION.
Improvements in Tubular Bells.
We, THOMAS LATHAM of Fleet Works Coventry in the County of Warwick
and JOHN HARRINGTON of 14 West Kensington Gardens in the County of
Middlesex, Manufacturers do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Heretofore tubular bells have been closed at one or both ends by a plug or cap,
which acted to communicate the vibration more quickly and completely from the
one side to the other. This mode of construction however had the disadvantage
screw
that the tube was sometimes injured in driving in a plug whilst a
plug or cap required very exact fitting to prevent chattering between it and
the tube.
Now, according to the present invention we are enabled to obtain all the advan-
tages of a plug or cap, combined with simplicity and cheapness of construction, by
the use of a cross bolt or plug.
In carrying the invention into effect we form near one or both ends of a tubular
bell, a hole in each side thereof, such holes being diametrically opposite to each
other and of such a size as to receive a hollow or solid cross plug or bolt, which is
brazed, soldered or otherwise fixed in position to ensure its solidity with the
tubular bell.
The cross plug or bolt may be of copper, brass or other suitable material.

page_text: In the accompanying drawings
Figure 1 is an elevation and Figure 2 is a plan of the upper end of a tubular
bell provided with the present improvement, both figures being drawn partly in
section.
a, is the tube of our improved tubular bell, b, b, are the holes in the sides thereof
through which the supporting cord passes, and, c, is a cross plug or bolt which is
represented as solid and which is passed through and rivetted into countersunk
holes formed near the upper end of the tube a. The cross plug or bolt c, may
however be hollow as shown by the dotted lines and instead of being rivetted in
position as shown it may be brazed, soldered or otherwise fixed in position, care
being taken that the joints are made perfectly solid with the tube so as to prevent
any chattering of the parts against each other.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
A tubular bell fitted with a cross bolt or plug at one or both ends substantially
as herein shown and described.
