declare the nature of this invention to be as follows;-
-
By means of a wheel made in such a manner that the said wheel will contract
or expand, this wheel to carry a certain number of advertisments known as
lantern slides, by means of a powerful light the slides are shown upon screen or
boards, this wheel is moved by dead weight round axle & by means of movable
cogs a star allows one at a time to pass, said star is worked by clock work.

We, WILLIAM JOHN HAWKINS, Photographer, and REGINALD HARCOURT WRIGHT,
Physician and Surgeon, both of l'artington, in the County of Chester, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
.
statement:-
Our invention relates to advertising apparatus of that kind wherein a series of
lantern slides or transparencies is mounted upon a wheel adapted to be intermit-
tently rotated and arranged in conjunction with a projecting lantern in such a
manner that as the slides are successively brought into focus a picture or other
advertisement will be projected on to a screen, sheet or other surface.
Apparatus of this kind as heretofore constructed is defective and mainly for the
reason that no efficient means are provided for accurately bringing the slides into
focus. The chief object of our invention is to overcome this difficulty and to this
end the slides are mounted in frames carried by arms upon a wheel which arms
are independently adjustable so as to permit of focussing the slides individually.
Our invention also comprises an escapement in the form of a star wheel, which
is operated by clock mechanism in such a manner that at predetermined intervals
the wheel is allowed to rotate under the action of a suitable motor, and a brake
for steadying the movement of the apparatus during the time that it is being
rotated by the motor so as to prevent the jarring or shaking which would other-
wise be produced when the wheel is brought to rest.

page_text: To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which;-
Figure 1 is a sectional side elevation of apparatus constructed according to
our invention;
Figure 2 is a sectional plan of the same:
Figure 3 is a section on the line - Figure 1 but drawn to a larger scale
illustrating the arrangement of one of the arms carrying a slide and also the
means which we employ for causing the intermittent rotation of the wheel:
Figure 4 is a plan view of the slide holder of one of the armis drawn to the
same scale as Figure 3: and,
Figure 5 is a side elevation of a brake which we use for steadying the motion
of the apparatus the said figure being drawn to a larger scale than Figures 1
and 2.
t
a is the box or framing in which the apparatus is mounted, is the wheel carried
in suitable bearings upon the shaft or spindle and d, d are the arms for carrying
the lantern slides, the said arms at their inner ends being carried in clips e, e
The
adjustable upon the rim of the wheel and fixed thereon by set screws e
arms d, d are provided at their outer ends with frames f, f in which the lantern
slides (one of which is indicated by the letter y in Figures 3 and 4) are mounted
The arms d, d are not fixed to the clips e, e but are made to slide therein in the
radial direction of the wheel set screws h, or the like being provided for securing
the said arms in any position.
With this arrangement it will be understood that the arms d, d can be arranged
nearer together or farther apart according to the number of slides which the wheel
is to carry so that the said wheel may be balanced, and that the frame for carrying
each slide is radially adjustable towards or away from the axis of the wheel b.
i is a lamp or other apparatus for illuminating the slides and j, j are the usual
lenses, the said lamp and lenses being adjustable upon the plate or bark of the
framing.
It will be noticed by reference to Figure 2 that the said lamp and lenses project
laterally from the said bar k and that the frames f, f of the arms d also project
laterally so as to pass in front of the lamp.
7 is a weight which serves as a motor for rotating the wheel the said weight being
connected to one end of a cord the other end of which is coiled around a drum
or pulley m on the shaft of the wheel in such a manner that the said weight
will rotate the wheel in the direction of the arrow Figure 1.
n is a clock mechanism which as shewn is also operated by a weight (indicated
at a) the movement of the said clock being controlled by a pendulum .
an
r.
is our star wheel escapement which serves to control the intermittent motion
of the wheel and which is mounted upon the outer end of a spindle y which
forms extension of the arbor of one of the clock wheels, the said
outer end of the spindle being carried in a bearing or bracket
This star wheel p. which is clearly shewn in Figure 3, is designed
to co-operate with cogs s, upon the clips, e the cogs being arranged
in a different plane from the cogs on the alternate clips. With this arrange-
anent it will be understood that as the star wheel pis rotated by the clock
mechanism the cogs s, will be alternately engaged with and released by the
said star wheel, that is to say, one of the cogs, say the cog s, will by bearing against
one of the teeth of the star pretain the wheel b stationary against the action of
the weight until such time as the said tooth has moved out of the path of the
cogs the wheel being then rotated until it is arrested by the next following
tooth of the star wheel which, during the time that the first mentioned tooth
of the star wheel was passing the cogs and moving out of its path was entering
the path of the next cog t and so on. In practice a uniform distance must be
maintained between the cogs so that each time the wheel is released by the
escapement it will move a sufficient distance to bring the slide next to that which
was previously exhibited into focus.

page_text: It will be obvious that the sudden stoppage of the wheel together with the
arms and slides carried thereby by the successive inpingement of the cogs s, t
against the star wheel would produce an amount of vibration which might con-
siderably impair the efficiency of the apparatus owing to the possible derangement
or shaking of the slides in their frames. In order, therefore, to prevent such jar
we make use of a brake arrangement for steadying the motion of the wheel. 'The
form of brake which we have found to give good results and which is indicated
by the letter in Figures 1 and 2 and which is shewn drawn to an enlarged scale
in Figure 5, comprises a recessed pillar in which is pivoted a block o acted
upon by a spring which normally tends to cause the said block to project beyond
the face of the pillar to form an inclined surface against which the arms d, das
the wheel rotates will impinge, the resistance which the backward movement of the
block, under the action of the arms d- and against the pressure of the spring,
offers serving to give the required check to the rotation of the wheel. It will be
understood that the position of the said brake and the strength of the spring
must be such that the wheel is practically brought to rest just at the moment
that the cog which is to retain the wheel comes in contact with the star wheel p.
By the time this bas taken place the arm of the slide being exhibited should just
have passed the extremity of the block so that the latter will have sprung out-
wards as indicated in Figure 5, and support the said arm during the time that the
slide which it carries is being exhibited.
We find it advantageous to place upon the top of the block wa pad y of india-
rubber.
The length of time during which a slide is being exhibited will depend upon
the rate at which the star is rotated and which of course is dependent upon the
clock mechanism.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. In an advertising apparatus wherein a series of slides are carried by a wheel
and adapted to be successively brought into the focus of projecting lenses providing
the said wheel with a series of arms adjustable radially and circumferentially upon
the said wheel and carrying the lantern slides, substantially as described.
2. In an advertising apparatus the combination of a wheel driven by a motor
the said wheel being provided with a series of circumferentially and radially
adjustable arms carrying lantern slides, a star escapement co-operating with
moveable cogs in connection with the said wheel and operated by clock mechanism
and a lamp and lenses for projecting the pictures or other advertisements on the
slides on to a screen or the like, substantially as described,
3. In an advertising apparatus the combination of a wheel driven by a motor,
