We, HENRY Moox, of. Osborne House, Alcester Road, Moseley, near the City
of Birmingham, Manufacturer, WILLIAM JOHN DAVIS and ERNEST EDWIN
MOTTRAM, both of 2, Pleasant Grove, South Shore, Blackpool, in the County of
Lancaster, Advertising Contractors, do hereby declare the nature of this inven-
tion to be as follows:
This invention consists of improvements relating to advertising clocks, our
object being to provide simple and effective means for automatically changing
the advertisements by the action of the clock mechanisin.
In the application of our invention we arrange in the clock case, preferably
beneath the ordinary dial face, the pair of prismatic frames on the sides or
panels of which the required advertisements are displayed. The case has a glass
front or is fitted with glass on both sides in addition to the front, according to
the position or service for which the clock is required."
The prismatic frames are rapidly rotated by means of suitable gearing
arranged in combination with the striking mechanism of the clock. Such rota-
tion is not continuous but is effected intermittently, each complete revolution
of the frames being performed in a number of stages or periods corresponding
to the number of faces on the frames each face having preferably a different
advertisement thereon. Each stage of movement is accomplished with a uniform
rapidity to give the necessary continuity of the advertisements, but a period of
rest is provided between each stage sufficient to permit of the effective separate
displayal of every advertisement on the frames.
We provide for the period of rest by the arrangement and combination of an
arm or arms mounted on one of the rotating spindles forming a part of or con-
nected with the striking mechanism, with a timing disc mounted upon one of
the rotating spindles forming a part of or connected with the ordinary time
mechanism of the clock. The said timing disc has a notched rim and the inner
portions of such rim are tapered or inclined from the narrow central web to the
respective edges of the periphery.
Upon each of the arms herein before referred to we attach a flat spring upon
one end of which is affixed a pin or peg projecting through the arm and beyond
its opposite side. On the rotation of the arm the projecting peg abuts against
the periphery of the timing disc and thus arrests the arm and the complete
advertisement rotating mechanism until one of the grooves or notches in the
rim is brought into alignment with the peg. The peg will then pass through
the slot, under the action of the mechanism which is then set free to again
revolve, move across the face of the disc, and on travelling up the inclined
surface of the rim will be pushed back, against the action of the spring, to per-
mit of its passing clear of the periphery as the arm rotates.
By the use of timing discs having rim slots of the required pitch working in
combination with one or more arms on the advertisement driving mechanism,

advertisements.

Improvements relating to Advertising Clocks.
We, HENRY Moox, of Osborne House, Alcester Road, Moseley, near the City
of Birmingham, Manufacturer, WILLIAM JOHN DAVIS and ERNEST EDWIN
MOTTRAM, both of 2, Pleasant Grove, South Shore, Blackpool, in the County of
Lancaster, Advertising Contractors, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
This invention consists of improvements relating to advertising clocks, our
object being to provide simple and effective means for automatically changing
the advertisements by the action of the clock mechanism.
On the accompanying sheets of explanatory drawings (five in number) to be
hereinafter referred to.
Figure 1 is an elevation representing the front portion of our advertising
clock, and Figure 2 a similar view showing the back portion of the same: the
wood or other casing of the clock being omitted in each view.
Figure 3 is an elevation (with the front plate. removed) showing the gearing
for driving the advertising display frames.
Figure 4 is a plan and Figure 5 an end view showing the display frames
driving gear and the intermittent stop mechanism. Figure 5ª is a sectional
end view of the timing disc.
Figure 6 is an elevation showing the intermittent stop mechanism.
Figures 1 and 2 are drawn to a smaller scale than the other figures.
The same reference letters in the different views indicate the same parts.
In the application of our invention we arrange in the clock case, preferably
beneath the ordinary dial face A, a pair of prismatic frames as BB (built up
of metal or other material) on the sides or panels of which the required adver-
tisements are displayed: the lower ends of the frame spindles are supported
in footstep bearings fixed on the bottom of the clock case. The case has a glass
front or is fitted with glass on both sides in addition to the front, according to
the position or service for which the clock is required.
In order to provide an expeditious means for attaching or removing the
prismatic display frames B B we slot the supporting brackets 623 in the manner
shown at Figure 4 and thus by slightly raising the spindles with their sup-
porting bushes we are enabled to readily and rapidly withdraw the adver-
tisement without interfering with the mechanism of the clock.
The frames BB' are rapidly rotated by means of suitable gearing arranged in
combination with that operating mechanism of the clock which is ordinarily
employed for striking or chiming purposes. The rotation is not continuous but
is effected intermittently, each complete revolution of the frames being per-
formed in a number of stages or periods corresponding with the number of faces
on the frames, each face having preferably a different advertisement thereon.
Each stage of movement is accomplished with a uniform rapidity to give the

page_text: necessary continuity of the advertisements, but a period of rest is provided
between each stage sufficient to permit of the effective separate display of every
advertisement on the frame.
The mechanism for driving the frames comprises the toothed wheels CC¹
mounted on the frame spindles respectively, the said wheels gearing respec-
tively with the face or contrite wheels 1) D' mounted on the spindle d.
The face or contrite wheel E fixed to the said spindle d gears with the pinion F
fixed to the spindle f and the pinion F which is.also fixed to the spindle f gears
with the wheel G mounted on the spindle g. The said spindle g is driven from
the first motion spindle by the wheel H and the pinion G¹ which gear together.
The spindle receives its motion through the pinion H which gears with a
wheel rotating with the fusee which is ordinarily employed for the operation of
the chiming or striking parts of the clock. The spindle f herein before referred
to is also connected by the gear wheels f f f and ft with the usual flier f.
We provide for the period of rest by the arrangement and combination of a
lever as J, preferably double-armed (mounted on one end of the spindle con-
nected by the gear wheels and with the afore-described frame driving
mechanism), with a timing dise K mounted upon one of the rotating spindles
as forming a part of or connected with the ordinary time or going mechanism
of the clock. The said timing disc K has a notched rim and the inner portions
of such rim are tapered or inclined from the narrow central web to the respec-
tive edges of the periphery as shown at Figure 5.
Upon the outer end of each of the arms of the rotating lever J, we affix
laterally a pin or peg as L. On the rotation of the lever the projecting pegs
abut in turn against the periphery of the timing disc K and thus arrest the
arm and the complete advertisement rotating mechanism herein before described,
until one of the grooves or notches in the rim of the disc K is brought into
alignment with the peg. The peg L will then pass through the slot, under the
action of the mechanism which is set free to again revolve, move across the face
of the disc, and pass out through a slot on the opposite side, or up the inclined
inner surface of the rim, the pin or peg L being for the latter purpose, fixed
to a spring piece permitting of lateral movement. This action is repeated on
every rotation of the arms of the lever J, and as there are two arms two pauses
are obtained during one complete revolution of the spindle on which the lever
is mounted.
To neutralize the effect of friction between the projection Land the periphery
of the timing disc K we taper or back off the said periphery between the slots
or notches as shown at Figure 6, in order that the surface in contact with the
projection L shall possess the properties of an inclined plane. By so doing the
pressure exerted through the arm I tends to accelerate the motion of the timing
dise and thus irregularities in the motion of the clock, due to the intermittent
frictional resistance of the projection L, are avoided.
By the use of timing discs having rim slots of the required pitch working in
combination with a lever having one or more arms rotating with the advertise-
ments driving mechanism we can arrange for the effective displayal of the whole
of a desired series of advertisements.
We provide for the disconnection of the advertisement rotating mechanism
to prevent its operation during the night or at other times when not required,
by a lever M pivotted on one of the clock frame plates, the free end of such
lever resting upon the periphery of the cam N rotated through gear wheels n,
1, 2, 3, and 4, from the ordinary spindle carrying the minute hand of the
clock. The cam N is so shaped that at a certain pre-determined time the free
end of the lever M will fall à sufficient distance to bring a lateral projection P
from the lever into such a position that it acts as an abutment for a peg Q,
projecting from the wheel hereinbefore referred to, thus stopping the adver-
tisement driving mechanism, until by the continued movement of the cam N
the lever M is raised at the pre-determined time,
