PROVISIONAL SPECIFICATION.
Improvements in Apparatus to be employed for Advertising
Purposes.
We JAMES HENRY PATTERSON JOHNSTONE, 57 High Road, Lace Designer,
and FRANK WILKINSON, Beeston Hall, Lace Manufacturer, both of Beeston,
Nottinghamshire, do hereby declare the nature of this invention to be as
follows:-
The apparatus consists of the following parts; a box of suitable size and shape,
made of wood or other suitable material or materials, is provided at the front or
upper part with a stereoscopic lens or lenses capable of adjustment either by means
of a rack and pinion, screw and wheel, or their equivalent.
The back of the box is somewhat lower than the front, to allow the top to be
covered by a fixed or moveable plate of glass, set at about an angle of forty-five
degrees, to light the interior of the box by day, or by gas or other light above it
by night.
The ends of the box are provided with bearings in which the axle of a cylinder
revolves.
The revolution of the cylinder may be effected by bevel toothed gearing or a
worm and wheel, either being actuated by a handle operated by an attendant or by
any person using the lens or lenses.
The cylinder may be formed with any number of flat sides to receive cards upon
which photographs may be mounted.
The cards may be secured to the cylinder by pointed pins, clamping screws or
spring clips. Or the cards may be linked together by tapes or bands of india-
rubber, or other material or their equivalent to form an endless chain of
photograph bearing cards.
One end of the cylinder carries a circular plate of metal having recesses formed
it its circumference equal in number to the sides of the cylinder, a spring catch
engages in one of the recesses, and holds the cylinder and photograph in proper
position to be seen through the lens or lenses, until changed for the next by partly
turning the cylinder.
་་་་་
Each photograph may represent the advertisement required alone, or in con-
junction with a scéne, portrait or other representation.
Two or more sets of advertising apparatus as above described may be placed end
to end, or a double row may be placed back to back and secured to a plain or
ornamental stand and fixed in any public resort.
Or
Or two or more sets may be placed end to end and secured to, or let into a wall
or other suitable surface.

Improvements in Apparatus to be employed for Advertising
Purposes.
We JAMES HENRY PATTERSON JOHNSTONE 57 High Road Lace Designer
and FRANK WILKINSON Beeston Hall Lace Manufacturer both of Beeston
Nottinghamshire 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 :—
DESCRIPTION OF THE DRAWINGS.
Figure 1, is a front view of the apparatus with a door removed to show a cylinder
hereafter referred to.
Figure 2 shows a left end view with the side removed.
Figure 3 an enlarged plan of one of the sides of the cylinder.
Figure 4 a front edge view of one of the cylinder sides.
Figure 5 an enlarged left end view of a stereoscopic lens frame.
Figure 6 shows an end view of a cylinder we employ when using an endless chain
of photograph bearing cards.
Figures 7 show a plan and edge view of one of the links of an endless chain.
The apparatus consists of the following parts "see Figures 1 and 2" a box 1 of
suitable size and shape made of wood or other suitable material, is provided at the
upper front part with a pair of stereoscopic lenses 2 carried by a frame 3 sliding in
a bracket 5, beneath the lenses the frame has a toothed rack 4 at each side, which
engage with two toothed pinion wheels secured on an axle 6 "shown in the enlarged
view Figure 5" the outer right end of the axle terminates in a nut 7 by which the
lenses may be adjusted.
The back of the box is somewhat lower than the front the top being covered by
a plate of glass 8 to light the interior of the box by day, or by gas or other light
above it by night.
The ends of the box inside are provided with bearing plates 9 in which the axle
of a cylinder 10 revolves.
The revolution of the cylinder is effected by bevel toothed gearing 11 actuated
by a handle 12 operated by an attendant or by any person using the lenses.
The cylinder may be formed with any number of flat sides "a twelve sided
cylinder is shown at Figures 1 and 2" to receive cards upon which advertisements
or photographs may be mounted.
Each photograph may either represent the advertisement alone, or in conjunction
with a scene, portrait or other representation.
A card may be secured to each side of the cylinder as shown by the enlarged
views Figures 3 and 4, the right end of each card being passed under a strip of
metal 13 which holds it down, a spring clip 14 holding it in position. The left end
of the card being held down by a strip of metal 15 bent to the form shown at
Figure 4 hinged to a plate 17 secured to the underside of the cylinder, the lower
inner end of the strip 15 being pressed upon by a plate spring 16 also secured to
the underside of the cylinder.
Or any number of cards bearing advertisements and photographe may be linked
together to form an endless chain, by placing the ends of each card under the
spring clips 18 of two series of links 19 like the one shown in plan and edge view
at Figure 7, the ends of each link being hinged to the ends of two adjacent links by
loops 20.
When endless chains of advertising cards are employed a smaller four sided
cylinder may be used provided with a flange 21 at each end, an end view of one
such cylinder with one end flange removed is shown at Figure 6.

page_text: Two or more sets of advertising apparatus as above described may be placed end
to end, or a double row may be placed back to back and secured to a plain or
ornamental stand of suitable height and fixed in any public resort.
Or two or more sets may be placed end to end and secured to, or be let into a
5 wall or other suitable surface.
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 :-
The construction and employment of advertising apparatus substantially as
O described and illustrated in the drawings annexed.
