Improved Means for Advertising.
1, VICTOR ISIDORE FEENY of 60 Queen Victoria Street, London, in the
County of London Patent Agent (a communication from the Western Clock
Advertising Company of 819 Market Street, City and County of San Francisco,
California, U.S.A., a corporation duly organized and existing under and by virtue
of the laws of the State of California) 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 :-
This invention relates to the general class of exhibiting mechanism, known as
advertising clocks.
It consists in the series of advertising placards, in connection with a clock-work
nechanism and intermediate devices for periodically exhibiting successive placards,
which will be hereinafter fully described.
In the accompanying drawings,
Figure 1. is a front elevation, a portion of the casing being broken away.
Figure 2. is a side elevation, part of the casing being broken away.
Figure 3. is a detail of the end of lever H.
A. is a casing of suitable ornamental character. In its lower front it has a
sight aperture a, the top of which has a hood a¹ which serves as a guide for the
successive advertising placards B, as they approach their point of dropping to
exhibit their faces. The placards are pivotally mounted in the circumference of
revoluble end disks C, carried by a shaft D, which is mounted in suitable
standards b.
In the top of casing A is a clock E having the usual dial and hands. The
mechanism of the clock is of the ordinary description and is designated
generally by e.
In the lower portion of the clock frame is a shaft F which carries a pinion t.
This pinion engages the gearing of the clock mechanism, as shown, whereby it and
the shaft F derive a rotary motion. Shaft F also carries a cam wheel G con-
sisting of a disk with a circumferential series of inclined drop planes or cams g.
His a pivoted lever, one extremity of which bears on the cams of wheel G, an
antifriction roller ŉ preferably intervening.
To the other extremity of lever H is connected an actuating pawl I which
engages with a ratchet J on the shaft D below. A retaining pawl K controls this
ratchet.
L is a gong, and M is a striker carried by the lever and adapted to hit the
gong.
The operation is as follows
--
The shaft F being rotated by the clock mechanism, the cams of wheel G bear
down successively upon the lever H, and successively relieve it.
Bearing down upon this end of lever H raises its other end, and this movement
lifts pawl I, which, through its engagement with ratchet J turns shaft D and the
end disks C.
A placard B is thus brought forward past the guide hood a' and it then drops by
gravity thus exposes its face.
Then the cam, relieving the lever H, said lever drops its lower extremity, and
lowers the pawl I for engagement with the next tooth of the ratchet J, and this
same dropping of lever H causes the striker to hit the gong and thereby attract
attention to the exhibition of the placard. The operation being repeated the
several placards are successively exhibited.

page_text: The time during which each placard is exbibited can be properly determined by
the movement given to the cam wheel G.
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
1st. An advertising clock, a driven shaft of which carries a cam wheel which
through a lever and a pawl and ratchet transmits rotation to a shaft upon which
are mounted disks carrying a series of swinging placards which are successively
dropped into sight by the rotation of the shaft, substantially as herein described.
2nd. An advertising clock, a driven shaft of which carries a cam wheel which
through a lever and a pawl and ratchet transmits rotation to a shaft upon which
are mounted disks carrying a series of swinging placards which are successively
dropped into sight by the rotation of the shaft, and a striker carried by the lever
and adapted to operate upon a gong, to call attention to the dropped placard,
substantially as herein described.
Dated this 20th day of June 1893.
