THE EXHIBITION OF ADVERTIZEMENTS
of
Near the top of au oblong or other suitable shaped case I fix an ordinary
clock; below the face of the dial is an opening in the case for the purpose.
exhibiting the advertisements
Now the means by which I cause the advertisements to appear without in any
way interfering with the works or movements of the aforesaid clock is, as follows,
viz-I insert a barrel inside the case so that as the barrel revolves it presents a
full face to the opening in the case.
On this barrel are fixed various advertisements which are presented one or more
at the time in the opening of the said case-The means by which and the way in
which this roller is made to move or revolve are a very important part of the
Invention as I totally disconnect the movements of the clock with the gearing-
which works the aforesaid roller thereby doing away with the liability of injury to
the delicate works of the clock which they would be liable to sustain from the
friction caused by the revolving of the said roller. therefore cause the said roller
to revolve Either by works which cause it to revolve a certain distance and then
stop for a certain period or by fixing to it a similar gearing that is employed in
causing the barrel of an ordinary musical box to revolve with the exception that
when one advertisement disappears and another one replaces it at the opening a

page_text: small bell sounds so as to call attention to the fact of a different advertisement
appearing this bell or alarm is worked by pins protruding from some part of the
barrel, which pins divide the advertisements and as the said pins revolve they
either release or force down a lever acting on an ordinary clock bell or gong.
This bell can be sounded in various ways as employed in ordinary clocks, the 5
only object of the bell sounding-being to denote a change of advertisement
The gearing working the roller is entirely disconnected with that working the
clock so that the clock can be wound up separately

FREDERICK WILLIAM LITTLE, of 26, Newman Street, Oxford Street, London, W.
Clerk, IMPROVED APPARATUS TO BE EMPLOYED IN CONNECTION WITH CLOCKS FOR
THE EXHIBITION OF ADVERTIZEMENTS
My Invention relates to improved means or apparatus to be employed in con-
nection with clocks, or clock cases, for the exhibition of advertisements, without,
in any way, interfering with the ordinary works of the clock. My invention will
be readily understood on reference to the accompanying drawings, in which
Fig 1 is a front view of a clock, or clock case, to which my improved advertising
apparatus is applied:
Fig 2, is a vertical cross section of the same; and
Fig 3 is a back view, the door of the case being removed.
:
t
In carrying out my Invention I fit near the top of the case A, an ordinary
clock B, and below which I form glazed openings C, C', in the case, for the purpose
of exhibiting the advertisements, in the manner as hereinafter described.
:
The means by which I cause the advertisements to appear, without in any way
interfering with the works or movements of the aforesaid clock is, as follows: viz,
I mount two drums or barrels D, D', inside the case A, so that as these drums or
barrels revolve they present either a full face, or a portion of their face to the
openings C, C¹, in the case.
Upon the surface of each of these drums or barrels are painted, fixed or other-
wise marked, advertisements, which, by means of the mechanism about to be
described, are presented, one or more at the same time, at the openings C, C¹, of
the case..
The means by which, and the way in which these drums or barrels are made to
revolve are a very important. part of the invention as I totally disconnect the
movements of the clock with the gearing which works the drums or barrels
thereby obviating liability of injury to the delicate works of the clock which they

page_text: would be liable to sustain from the friction caused by the revolving of the said
drums or barrels.
I therefore cause the said drums or barrels to revolve by means of a mechanism
arranged as follows: I fix on the top and on one side of the case A, a clock move-
ment F, F, indicated in dotted lines in the drawing, of ordinary construction, which
sets in motion a disc H around the periphery of which a suitable number of pins
is fixed. This disc acts by means of its pins h, upon a lever L. A greater or less
number of pins may be carried by the disc according as it is desired that the
advertisement should appear more or less often at the openings C, C¹. The lever L,
carries a pawl or clawker K, an arm M, for preventing the said pawl or clawker
falling too low at the time it performs its function, and a pin N, upon which rests
a click P. This click P engages with pins e, which are fixed on the inner face of
a ratchet wheel E, which is mounted upon the axis of the upper drum D. This
ratchet wheel is maintained in position by means of the click P, and a piece Q
provided with a friction roller q. The object of the pawl or clawker K, is to cause
the ratchet wheel E, to revolve, and, at the same time, the drum or barrel D, in
such a manner that, when the advertisements disappear at the openings C, C¹,
other advertisements replace it.
The lower drum or barrel D¹, receives its movement from the upper one by
means of the toothed wheels d, d', which are fixed to the said drums or barrels.
On the periphery of the toothed wheel d, are pins or studs d*, which engage
and release a lever R mounted upon the axis S, upon which is fixed the arm T, of
the hammer U, which strikes the bell or alarm X, each time the drum or barrel
has turned a distance equal to that between two of the pins of the drum, and so
calls attention to the fact of another advertisement, or advertisements, appearing at
the openings C and C¹
This bell, alarm or gong can be sounded in various ways, as employed in
ordinary clocks, the only object of the bell, alarm or gong sounding, being to denote
a change of advertisement.
Z, Z, are springs, the first of which acts upon the piece Q, and the latter upon
the lever L, for the purpose of restoring the said piece and lever to their normal
position.
Although I have described and shewn my invention as arranged for two drums
or barrels, I wish it to be understood that I may use one drum or barrel, or three,
or more, drums or barrels, also that the means or apparatus herein described and
shewn as applied to a clock or clock case may likewise be applied to other cases
or boxes.
Having now described the nature of my Invention, and the manner in which the
saine may be performed, I declare that I claim.
1. Constructing, arranging and fitting clocks, or clock cases, with means or
apparatus for the exhibition of advertisements in the manner substantially as
herein described, without in any way interfering with the works of the clock.
2. In combination with, and actuated by ordinary clock movement F, F, the
disc H, provided with pins h, for the purpose of operating the lever L, and causing
the drums or barrels bearing the advertisements to advance or partially revolve at
certain determined intervals of time as herein described.
3. The special arrangement of mechanism actuating the drums or barrels, the
same consisting of the pin disc H, the lever L, pawl or clawker K, arm M, click P,
piece Q, with friction roller q, and ratchet wheel E provided with pins e, and
mounted upon the axis of the upper drum or barrel, all as herein described and as
shewn in the drawings.
4. In combination with the mechanism herein described, the drum or barrel, or
drums or barrels, carrying advertisements and so arranged as to be operated at
certain determined intervals of time by the independent clock movement F, F,
the said barrels or drums being provided with toothed wheels for the purpose of
transmitting motion from one barrel or drum to another, or others.

page_text: 5. In combination with the upper drum or barrel, and its toothed wheel, the
means herein described and shewn for operating the striking mechanism at each
change of advertisement.
