Improved Means for Advertising.
I, WILLIAM JOHN HAWKINS Photographer Thelwall Lane Latchford Cheshire
do hereby declare the nature of my invention for an IMPROVED MEANS FOR
ADVERTISING to be as follows:-
Box 3 ft. square 18 in. deep, in which is placed a 3 ft. wheel, upon this wheel
transparent lantern slides with advertisements, these revolve in front of a powerful
lamp, by shining through condensor & object lens the picture or advertisement is
thrown upon a screen 4 ft. wide. These advertisements stop dead upon the screen
for the space of one minute, & then jump at one bound to the next. The wheel is made
to hold 30, so that the same advertisement comes around every half hour. A clock
is arranged in such a manner that this minute work guides the advertisement wheel.
The clock work, & wheel is driven by weight, the clock moves up a lever, once a
minute. When the lever is free of the advertising wheel, it moves to the next, but
is prevented moving more than one on a/c of the lever falling into position. It
will take one minute for the clock to raise the lever again.

COMPLETE SPECIFICATION.
Improved Means for Advertising.
WILLIAM JOHN HAWKINS late of Latchford Warrington, now of Hawthorn
Villa Flixton near Manchester Photographer 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 :-
The apparatus which is automatic is enclosed in a box (wood) 3 ft. 2 in.
square x1 ft. 6 in., has first, a wheel 2 feet 9 in. diameter, to which from the
rim are placed 30 sheets of glass 31 in. x 3 in. upon each of these glass squares,
is an advertisement or view, the said picture is put upon the glass by means of
photography, this wheel has a spindle running through & fixed to each side of the
box to this spindle a winding gear is fitted so as to wind the cord round the said
spindle, the weight placed at the end of cord, which cord is run over a pulley, &
by the falling of the weight turns the wheel. The rim of wheel 2 in. wide is a
series of pins placed in twos in an upright position 2 pins for each slide or square
of glass 60 in all, over this rim is placed a double tongue lever, each tongue to fit
one of the pins, by the twisting of the lever, first one pin is released & then the
second, by falling back into first position, allowing the wheel to travel the distance
of one glass square, until the first tongue of lever stops it dead, & it repeats the
action, one minute elapses from the meeting of the first pin to releasing of the
second pin.
At the clock end of lever, is fitted to the clock a loose wheel with pins upon the
edge & surface, the wheel under this is fitted with pins upon the surface & is worked
by the clock.
By the circular movement of this lower wheel, the top or loose wheel is moved
round by the edge pins coming into contact with the surface pins of the lower
wheel. By means of this circular movement the loose wheel surface pins rises the
lever & releases the pin upon the wheel A.

page_text: The clock & big wheel to be wound up as often as required. Underneath the big
wheel to come under the glass is fixed a 4 in. condensing lens & on the other side
of the rim or circle of the glass is fixed a double acromatic lens. When the strong
light which is under the 4 in. condensing lens is lighted, the light by shining
through the condenser, through one of the glass squares also through the acromatic
lens streams through a small hole in the box & on to the screen, wall or hoarding,
and shows the advertisement or picture which upon the small square of glass,
upon the big wheel.
The lime which is attached to the burner is turned once in a revolution of the
big wheel, a small bar is attached to one of the spokes of the big wheel & turns
another lever placed underneath the lime. To put the light out a platform is put
upon the bottom of box directly under the big weight, that drives the advertising
wheel. When this weight comes in contact with this platform, it presses it down
& with a connection with platform & taps puts it out.
Improved means of advertising by night in the open air upon walls & other
places, to which a board 8 feet square can be placed, this invention is to bring a
fresh picture upon the said board at stated intervals without the aid of any person
to be in attendance. The following automatic arrangements are here given. Fig. 1
and 2, shows the machine closed in a box 3 ft. 2 in. square by 18 in. wide, large
wheel with 10 spokes & iron felly or band 2 in. wide, fitted to this iron felly are tin
grooves X. in these grooves the transparencies B are placed.
Lime light burner C. 4 in. condensor E. acromatic lens F. this acting in the
same manner as the magic lantern. The pictures to be exhibited passes between
the condensor E & lense F. To keep these pictures at stated intervals & when
time is up, to move to the next, is the object of this invention. Clock work G.
upon the front plate of this clock are two wheels H & I. H is worked direct from
clock, the pins upon face of this wheel coming into contact with pins upon wheel I,
this wheel which is loose is forced round, the end of lever bar J which rests upon
the pins in the face of wheel I. By the circular motion of this wheel it raises the
end J & gives a circular motion to the rod, which at the opposite end to J is fixed
a double tongue head K. Upon the iron felly of wheel A is fixed a number
of pins L two to each transparency fixed to the wheel Fig. 2, these pins are placed
one a little behind the other, the cord M running over pulley pulls the wheel round.
When the head K stops the first pin, the clock by raising J. moves K first tongue
off the pin, the second pin then comes against the second tongue, the first pin is
now past the first tongue. When the loose wheel on clock is released from J,
K falls back into place, the wheel is again caught, by 1st pin of next two, upon
first tongue.
By this means each transparency is brought in its turn & stayed between E & F.
Platform N the weight by falling upon it, pulls the connection & turns the two
gas taps O. O. and so puts the light out. To turn the lime, R will at once show it
the lime P is upon a spindle this spindle has a clock wheel at the base of spindle an
elbow-wheel works into this, from this elbow-wheel a shaft is carried, upon the end of
this shaft is placed a star wheel, every time the spoke Q passes this star wheel it
moves one of the arms of the star by this action the circular motion is given to
the lime.
S is the oxygen pipe from cylinder U to burner C.
Tis gas pipe connecting burner C to surface gas main.
V the pendulum of clock, W a stop catch to stop wheel A rebounding.
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. I claim the formation of the wheel A which enables a glass transparency to
move between the condensor & lens in such a manner that each transparency is in
exact position & requires no focussing, & will show each picture sharp & clear.

page_text: 2nd. The formation of the double tongue lever and pins I to said wheel by this
action to stop said wheel at stated interval.
3rd. The loose wheel I attached to clock the pins set in this wheel in such a
manner as to raise the lever J at stated intervals.
4th. Also the wheel H its pins coming into contact with wheel I.
5th. Also the arrangement for turning the lime as shown by R.
6th. Also platform & connections for the purpose of turning gas off as shown N
and O. O.
