Improved Apparatus for Displaying or Exhibiting Advertisements or
Pictures.
We, JOSEPII BISPHAM LEATHER BARROW, of York House, Dickinson Road, Long-
sight, Manchester, in the County of Lancaster, Engineer, and THOMAS BUTLIN
MARGETTS, of Flower Dale, Table Cape, Tasmania, Grazier, do hereby declare
the nature of this invention to be as follows:-
-
This invention relates to that class of advertisements or picture displaying or
exhibiting machines wherein the subjects to be displayed are photographed
painted or printed upon glass or other transparent plates which are arranged
around a disc or wheel which is intermittently caused to make a small portion of
a revolution at a time, so as to bring the subject between an illuminated lantern
lens and a screen, in such a way that the representations of various pictures or
advertisements will each in its turn be exhibited or displayed upon the said
screen for a given time.
These discs or wheels are usually caused to move the required distances at the
proper times by means of expensive clockwork, and the object of our invention
is to dispense with such clockwork, and to construct a very simple and efficient
automatic apparatus which will effect the same object.
We use a plain simple disc or wheel to the periphery of which the transparent
pictures or advertisements are attached by frames in such a way as to radiate
from the centre, their faces being parallel to the face of the disc or wheel; and.
on one side of the said disc or wheel we fix in the face of the same a series of
pins or projections.
At a convenient distance from the disc or wheel we fix a bracket supporting the
fulcrum of a lever one end of which is provided with a spring clip or other
suitable elastic connection or arrangement so formed that as the said lever is
caused to oscillate it shall at each oscillation leave one of the said pins or pro-
jections on the disc or wheel and take hold of the next, so that as the said lever
is caused to oscillate to and fro at regular intervals it will at each oscillation cause
the disc or wheel to be turned a portion of a revolution corresponding with the
distance between the frames and thus change the picture or advertisement.
The intermittent oscillation of the lever caused at suitable intervals in the
following manner. The other end of the lever is made or provided with a scoop
or receptacle which projects beneath the mouth or delivery orifice of a box or
hopper which is fixed to the wall or otherwise above the scoop, and a receiver of
convenient form is placed on the ground or floor below the same.
The hopper
is filled with dry sand or other suitable dry and heavy powder or granulated
material, and the mouth or discharge orifice thereof at the bottom is fitted with
a valve upon opening which the sand or other material will flow through the

page_text: mouth or orifice into the scoop at the end of the lever. As soon as a sufficient
weight has accumulated in the scoop it causes that end of the lever to descend,
and the other end thereof rising will cause the disc or wheel to perform the
portion of a revolution necessary for changing the picture or advertisement.
The sand from the scoop is discharged into the receptacle beneath and this end
of the lever being thereby lightened, rises again and causes the other end of the
same to descend and take hold of a fresh più or projection on the dise or wheel,
and so on at intervals continuously so long as the hopper contains any of the
sand or other heavy material. The length of the intervals may be varied by
opening or closing the valve more or less so as to regulate the descent of the sand
or other material, and when the hopper becomes empty the action will cease
altogether, but may immediately be set to work again by the attendant lifting up
the full receptacle and "dumping" its contents again into the hopper.

COMPLETE SPECIFICATION.
Improved Apparatus for Displaying or Exhibiting Advertisements or
Pictures.
We, JOSEPH BISPHAM LEATHERBARROW, of York House, Dickinson Road, Long-
sight, Manchester, Engineer, and THOMAS BUTLIN MARGETTS, of Flower Dale,
Table Cape, Tasmania. Grazier, 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:-
This invention relates to that class of advertisement or picture displaying or
exhibiting machines wherein the subjects to be displayed are photographed
painted or printed upon glass or other transparent plates which are arranged
around a disc or wheel which is intermittently caused to make a small portion of
a revolution at a time; so as to bring the subject between an illuminated lantern
lens and a screen in such a way that the representations of various pictures or
advertisements will each in its turn be exhibited or displayed upon the said
screen for a given time.
These discs or wheels are usually caused to move the required distances at the
proper times by means of expensive clockwork, and the object of our invention
is to dispense with such clockwork and to construct a very simple and efficient
automatic apparatus which will effect the same object.
On the accompanying drawing we shew the manner in which we carry our
invention into practical effect,-
Fig. 1 being a front elevation and Fig. 2 a side elevation of the improved
advertising or picture displaying machine.
According to our invention we use a plain simple disc or whee! (A) to the
periphery of which the transparent pictures or advertisements are attached by
frames (B) in such a way as to radiate from the centre, their faces being parallel
to the face of the disc or wheel and on one side of the said disc or wheel, we fix
in the face of the same a series of pins or projections (C).
At a convenient distance from the disc or wheel we fix a bracket (D) supporting
the fulcrum of a lever (E) one end of which is provided with a spring clip (F)

page_text: or other suitable elastic connection or arrangement so formed that as the said
lever is caused to oscillate it shall at each oscillation leave one of the said pins
or projections (C) on the disc or wheel and take hold of the next so that as the said
lever is caused to oscillate up and down at regular intervals it will at each
oscillation cause the disc or wheel (A) to be turned a portion of a revolution
corresponding with the distance between the frames and thus change the picture
or, advertisements.
The intermittent oscillation of the lever is caused at suitable intervals in the
following manner: —The other end of the lever is made or provided with a scoop
or receptacle (G) which projects beneath the mouth or delivery orifice (H) of a
box or hopper (I) which is fixed to the wall or otherwise above the scoop and a
receiver (J) of convenient form is placed on the ground or floor below the same.
The hopper (I) is filled with dry sand or other suitable dry and heavy powdered
or granulated material and the mouth or discharge orifice thereof at the bottom
is fitted with a valve (K) upon opening which the sand or other material will flow
through the mouth or orifice into the scoop (C) at the end of the lever.
As soon as a sufficient weight has accumulated in the scoop it causes that end
of the lever to descend and the other end thereof rising causes the disc or wheel (A)
to perform the portion of a revolution necessary for changing the picture or
advertisement.
The sand from the scoop is discharged into the receptacle (J) beneath and this
end of the lever being thereby lightened rises again and causes the other end
of the same to descend and take hold of a fresh pin or projection (C) on the disc
or wheel, and so on at intervals continuously so long as the hopper contains any
of the sand or other heavy and like material. The length of the intervals may
be varied by opening or closing the valve (K) more or less so as to regulate the
descent of the sane or other material, and when the hopper becomes empty the
action will cease altogether, but may immediately be set to work again by the
attendant lifting up the full receptacle (J) and "dumping" its contents again into
the hopper. Or the hopper (I) may be interchangeable with the receptacle (J)
and each be fitted with a false floor (I*) and made to fit into the upper part of
the outlet (H).
To facilitate the tipping of the scoop it may be hinged to the lever (E) with a
preponderating balance on the lever side of the hinge and designed to tip up
quickly, as indicated by dotted lines, when the weight of the same lowers the
lever, and reset itself automatically. The tipping movement is limited by a
small projection (L) on the hinge coming against the lever.
In addition to the lever and clip we may employ a falling weight and cord as
shewn by dotted lines for driving the disc (A) and use the lever and clip as an
escapement."
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1: In apparatus for displaying advertisements or pictures and in means for
operating such machines, a magic lantern a disc or wheel with radially disposed
frames on its periphery adapted to rotate and bring the said frames across the
line of projection of the said lantern, a series of pins on the edge of the said wheel
corresponding to the spacing of the said frames, a lever mounted upon a fulcrum
and at one end engaging intermittently with the pins on the wheel under
successive oscillations, and thereby propelling the wheel, a scoop fitted with
granular material, such as sand, and provided with a valve controlled outlet,
substantially as herein set forth and illustrated on the accompanying drawings.
2: In means for propelling a disc or wheel for the purposes aforesaid pins on
the edge of the said wheel, a pivotally mounted lever with spring clip at one
end and a scoop at the other end and a hopper fitted with granular material

page_text: immediately above the scoop with valve controlled outlet, substantially as herein
set forth.
3: The combination and arrangement of parts substantially as herein set forth
and illustrated on the accompanying drawings.
Dated this 12th day of May 1900.
