Improvements in Pneumatic Attachments for Acting on the
Movement of Repeating Clocks and other Time-keepers.
I, GEORGE GRANT LOBBAN, of 33, Mornington Road, in the Parish of
St. Pancras, in the County of Middlesex, Gas Engineer, do hereby declare the
nature of this invention to be as follows:
My improvements consist of a piston, valve, or bag of india rubber or other
flexible material acting on, or connected with, the lever, or other device for con-
trolling the repeating portion of the striking part of the clock or other time keeper;
this is connected by a pipe or tube either flexible or otherwise with an india rubber
ball or squeeze, the compression of which at any distance from the clock acting
on the piston, valve, or india rubber or other flexible bag, frees the lever or
other device controlling the movement, thus causing the clock or timekeeper to
strike.
Dated this 19th day of November 1890.

COMPLETE SPECIFICATION.
Improvements in Pneumatic Attachments for Acting on the
Movement of Repeating Clocks and other Time-keepers.
I, GEORGE GRANT LOBBAN, of 33, Mornington Road, in the Parish of
Saint Pancras, in the County of Middlesex, Gas Engineer, 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 consists of the adaptation of the well known principle of the
pneumatic bell to repeating clocks & other timekeepers, whereby the clock or time-
keeper may be caused to strike, such clock or timekeeper being at a distance from
the person operating it.
This may be done as follows, either with a bellows or other shaped bag A. Fig. 2.
of india rubber or other suitable material of a flexible nature or a cylinder &
piston B. Fig. 1. either attached to the frame holding the movement or to the outer
caseing of the clock or timekeeper and acting on the lever, C. Figs. 1. & 2. or other
device in connection with & starting the striking portion of such timekeeper; the
bellows or other shaped bag or cylinder is connected by means of a small tube or
pipe D. Fig. 1. (flexible or otherwise) with a pear shaped or other suitable
squeeze or push E. Fig. 1. by the compression of which the bellows or other shaped
bag is caused to expand or the piston rod to rise, as the case may be thus moving
the lever or other device in connection with and controlling the action, so causing
it to strike.
I do not bind myself to these or any other modes of working, but prefer to use
one or other of the above described methods.
Having now particularly described and ascertained the nature of said
my

page_text: invention, and in what manner it is to be performed, I declare that what I
claim is
1. The general application of the pneumatic principle as applied to repeating
clocks and other timekeepers.
2. Any and every mode of applying it to such purpose.
Dated this 7th day of March 1891.
GEORGE GRANT LOBBAN.
