PROVISIONAL SPECIFICATION.
Improvements in Appliances for Displaying Advertisements,
Information, or the like.
We, FREDERICK WALTER BLOOD, of 70 Grafton Street, Liverpool, in the
County of Lancaster, Packing Case Manufacturer, and CHARLES BATES of
219 Beaufort Street, Liverpool aforesaid, Sign Writer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to appliances for displaying advertisements, information
or the like, its object being to provide a simple appliance whereby the various
matters displayed may be changed at intervals either automatically or otherwise.
In carrying the invention into effect, we construct a frame within which we
mount a series of bars, preferably of a triangular cross section, capable of rotation
or oscillation about their longitudinal axis, and bearing the advertisements on
their various faces. The bars may be mounted parallel to each other in a
horizontal position, or in any other desirable manner. It is preferable, however,
to arrange them one above the other, so that their forward faces form a continuous
surface upon which the advertisements may be placed.
The axles of the bars are all connected by levers or other suitable mechanism
with an operating device upon or in proximity to the frame in such a manner that
the whole or any given portion of the bars may be turned to expose a fresh set of
advertisements, etcetera. The movement of the bars may be effected by hand, or
they may be so connected to a spring or other motor that their movement may be
performed automatically at stated intervals.
The appliance may be arranged as a fixture, or it may be alapted to be carried
or wheeled through the streets.

COMPLETE SPECIFICATION.
Improvements in Appliances for Displaying Advertisements,
Information, or the like.
We, FREDERICK WALTER BLOOD of 70 Grafton Street, Liverpool, in the
County of Lancaster, Packing Case Manufacturer, and CHARLES BATES of
219 Beaufort Street, Liverpool aforesaid, Sign Writer, 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 appliances for displaying advertisements, information,
pictures, scenery or the like, its object being to provide a simple appliance whereby
the various matters displayed may be changed at intervals either automatically or
otherwise.
The invention is best described by aid of the accompanying drawings, in
which:-
Figure 1 is a front elevation with a portion of the framing removed to show the
gearing;
Figure 2, a transverse section;
Figure 3, a side elevation;
Figure 4, a longitudinal section on an enlarged scale;
Figure 5 CHASE Coation

page_text: Figure 6 an end elevation on an enlarged scale.
In these
A, is the frame within which we mount a series of bars B, preferably of a
triangular cross section, capable of rotation or oscillation about their longitudinal
axis, and bearing the advertisements, pictures, information, etcetera, on their various
faces. The bars B may be mounted parallel to each other in a horizontal position,
or in any other desirable manner. It is preferable, however, to arrange them one
above the other, as shown in the drawings, so that their forward faces form a
continuous surface upon which the advertisements, pictures, etcetera, may be
placed.
The axles of the bars B are all connected by toothed gearing C or other
suitable mechanism.
D is a handle or lever having a ratchet d adapted to operate the ratchet wheel E
which is mounted on and secured to the axis of one of the toothed wheels C. By
moving this handle, the whole of the bars B may be turned to expose a fresh set of
advertisements, pictures, etcetera. F is a hinged flap adapted to press upon the
faces of the bars B and controlled by a spring f. By means of this hinged flap,
the surface of the bars is kept level, as the tension of the spring / keeps the hinged
flap pressed against the face of the bars so that their flat faces are all kept in line.
Instead of the movement of the bars B being effected by hand, they may be so
connected by a spring or other motor, or to the axle or wheel of a vehicle, that
their movement may be performed automatically at stated intervals.
The appliance may be arranged as a fixture or it may be adapted to be carried
or wheeled through the streets. It is well adapted for stage scenery, where the
scenery has to be changed with great rapidity, in which case it is arranged at the
back of the stage and the bars turned to expose a fresh scene at the conclusion of
cach act, or at other stated intervals.
It is evident that a portion of the bars B may be made to move independently of
the others, or some of them may be fixed and the others made capable of rotation
or oscillation about their longitudinal axis.
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. An appliance for displaying advertisements or the like in which a series of
bars B mounted parallel to each other are made capable of rotation or oscillation
about their longitudinal axes and bear advertisements, pictures, information, etc. on
their various faces, the axes of said bars being connected by tooth gearing or other
suitable mechanism, whereby on rotating one of the toothed wheels all or a portion
of the bars are rotated simultaneously to expose a fresh advertisement, picture or
the like substantially as described.
2. The general combined arrangement and construction of parts forming the
improved appliance for displaying advertisements, information or the like substan-
tially as set forth.
