Improvements in Clocks.
I, EDWARD THURSTON CHASE, of 902, Chestnut Street, Philadelphia Pennsylvania,
United States of America, Watch Maker, 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 in general to striking and chimney clocks, and more particularly
to that class of clocks called "Hall Clocks"
In many hall clocks the sound of the gong is so faint as to be heard but a very
short distance, and hence the usefulness of the clock is greatly impaired; the object
of my invention is to furnish a device by means of which the sound of the gong or
gongs will be increased and an otherwise practically unsaleable clock made saleable
and useful.
In the accompanying drawing in which similar letters of reference indicate similar
parts throughout the several views.
Figure 1 is an elevation of the back of a hall clock showing the gongs and bracket
to which they are secured, and, my device for increasing the sound.
Figure 2 is a side elevation of the same, and
Figure 3, a section of bracket a on line 1, 2, Figure 1.
A is the gong, B a bracket to which the gong is secured, C the back and D the
bottom of the clock The sides and front of the case are not shown.
a is a bracket
attached to bracket B, and b a rod one end of which is attached to bracket a and the
other of which rests either directly upon the bottom D of the clock or upon a support c
which is placed upon the bottom D.
The bracket a which is preferably constructed of metal is secured to the bracket B
which carries the gongs The lower part of this bracket a is furnished with a boss d
which is bored and threaded The upper end of the rod 6 is threaded as shown and
is screwed into boss d, its lower end resting either directly upon the bottom of the
clock, or preferably upon a metal support c which rests upon the bottom D. The
rod is screwed down so as to make a firm contact with the support c, and this rod
may be constructed either of wood or metal and may be either hollow or solid. It
will be understood that the connection between the bracket B and bottom D may be
made simply by a rod one end of which touches the said bracket and the other the
bottom, but the manner in which the connection is shown as made in the drawings is
preferable, for it may be adjusted at any time.
It will be further understood that by the bottom D of the clock I mean any
diaphragm placed across the case of the clock and secured to the sides and back of
the case, in the drawings the bottom D is shown near the lower part of the case but
this bottom may be raised to any height, provided of course, that it is not so high as
to interfere with the action of the pendulum.
The device above described and shown greatly increases the sound of the gongs in
all chunney and striking hall-clocks.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is :-
First. In a striking or chimney clock a rod supported thereon one end of which
bears against the bracket carrying the gongs and the other against the bottom of the
clock, substantially as and for the purposes set forth.
Second. The combination with the gong bracket and bottom of a striking or
chimney clock of a bracket having a threaded boss, a rod one end of which is

page_text: threaded and screwed into said boss and a support resting upon the bottom of
the clock and against which the lower end of said rod bears substantially as
set forth.
