Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, DAVID WAUDE, of 96 Andover Road Seven Sisters Road, London, N in the
County of Middlesex, Engineer, do hereby declare the nature of my invention for
IMPROVEMENT IN THE ARRANGEMENT' AND APPLICATION OF DOOR KNOCKERS AND
BELLS, to be as follows:-..
( An arrangement in combining Door Knockers and Bells, by which the act of
Knocking rings a bell on the inside of the door.
In carrying this into practice, the bell is fixed to the inside of the door, and
communicates with the Knocker by means of a rod, or piston, passing through &
hollow stud, one-end of which stud is fixed in the Knocker, and the other, or inner
end supports the bell and the hammer which strikes the bell. The rod, by being
driven by the Knocker, actuates the hammer which strikes the bell.
On the Knocker there is a spring stud or a hinge, which may be pressed upon
when knocking so as to drive in the rod. The spring stud may be dispensed with
and the Knocker made to ring the bell whenever it is used.
I claim the above mentioned arrangement, a rod going through a hollow stud or
tubing; the hollow stud supporting on the inner end the bell and likewise the bell
hammer, the inner end of the rod resting against the hammer and actuating it
every time the Knocker is used; or actuating it only when the person wishes the
bell to ring, which is effected by pressing down the spring stud or hinge, to bring
a shoulder in contact with the outer end of the rod.

County of Middlesex, Engineer, do hereby declare the nature of my invention
for IMPROVEMENT IN THE ARRANGEMENT AND APPLICATION OF DOOR KNOCKERS
AND BELLS BY WHICH THE ACT OF KNOCKING RINGS A BELL ON THE INSIDE of
THE DOOR, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In carrying this into practice, the Bell, E in the accompanying drawings is
fixed to the inside of the door and communicates with the Knocker, A, by means
of a rod or piston, C, passing through a hollow stud, D, one end of which stud is
fixed in the Knocker and the other or inner end supports the Bell, and the
hammer, F, which strikes the bell. The rod, C, by being driven by the Knocker, A.
actuates the hammer, F, which strikes the bell, E. On the Knocker there is a
spring stud or hinge, B. which may be pressed upon when knocking so as to drive
in the rod or piston, C. The spring stud or hinge may be dispensed with and the
Knocker made to ring the bell whenever it is used.
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
In the above mentioned arrangement,―
1, The rod, or piston, C, passing through the hollow stud or tube D and with its
inner end resting upon the hammer F and actuating it when the Knocker is used.
II. The hollow stud, or tube D, supporting at its inner end the bell E, and the
bell hammer, F.
3, the spring stud B, or hinge attached to the Knocker in such a way as to
bring a shoulder in contact with the outer end of the rod, when the spring is
pressed upon by the fingers in Knocking, but when not pressed upon the rod is not
actuated and the bell does not ring.
Dated this 20th day of September 1884.
