PROVISIONAL SPECIFICATION.
Improvements in Advertising Devices and Apparatus.
I GEORGE ANDREW MACBETH of 41 Conyers Road Streatham, Surrey S.W.
Engineer do hereby declare the nature of this invention to be as follows:-
My invention has reference to an improved system of advertising and is
particularly applicable to wheeled vehicles or machines and has for its object the
economical and effective display of advertisements and notices in an attractive and
public form.
I am aware that attempts, have hitherto been made to utilise the wheels of vehicles
for advertisement purposes, but they have been unsatisfactory by reason of the said
advertisements revolving with the wheel, and rendering them difficult to be read
or deciphered.
Now my invention overcomes this objection and provides a means whereby the
advertisements or notices are always capable of being read notwithstanding the
revolution of the wheel.
I will now describe my invention with reference to the application to one wheel
of a vehicle. In carrying out the same I attach to, or mount upon, the wheel, a
plate or tablet of circular, or other form, or shape, whereon is displayed the
required advertisement or notice, the said tablet being so weighted and arranged
that it tends to remain in a stationary or nearly stationary position with respect to
the wheel, although the wheel freely revolves. This plate or tablet may be carried
on suitable rollers or projections attached to the wheel or may be mounted on arms
extending to the centre of the wheel or it may be attached to a second tablet fixed
to the wheel. In some cases I employ a second tablet or plate which can be or is
attached to the wheel and revolves therewith.
One of the said tablets can be perforated with the required design or advertise-
ment, and the other may be colored with one or more colors so that the said colour
or colours may be visible through the said perforations. In other cases I employ
designs.or figures on the fixed tablet, and arrange the perforated tablet so that
when the wheel revolves peculiar optical effects are produced.

Improvements in Advertising Devices and Apparatus.
I, GEORGE ANDREW MACBETH of 41 Convers Road Streatham Surrey S.W.
Engineer 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 :-
My invention has reference to improvements in advertising devices and apparatus
applicable to the wheels of vehicles and of the character and kind described and
set forth in the Specification left with my application for provisional protection.
I will now proceed to describe my invention, reference being had to the accom-
panying drawings of which
Figure 1. is a front elevation of my improved advertising apparatus shewn
attached to the wheel of a vehicle.
Figure 2. is a side elevation of same shewn partly in section.
Figure, 3. is a side. elevation partly in section and shewing my improved
apparatus with two tablets or plates one (the back plate) being attached to and

page_text: capable of revolving with the wheel, the other (the front plate) being loosely
mounted, and caused to retain about a vertical position by means of a weight.
Figure 4. is a plan of the fixed back plate which may be painted in two or more
colours.
Figure 5. shews the front plate or tablet with perforated letters through which
the colours of the back plate or tablet can be seen.
Figure 6. is a sectional elevation to an enlarged scale shewing the method of
attaching the back plate to the wheel and of mounting the loose front plate.
Figure 7. is a plan of same.
Figure 8. shews another arrangement for attaching the back plate and of
mounting the loose front plate on rollers.
Figure 9. is a plan of same.
Figure 10. shews an arrangement in which the loose front plate is carried by
projections or spindles attached to the back plate.
Figure 11. is a part plan of same.
Referring to Figures 1 & 2.-When the desired advertisement is painted or
otherwise shewn on the surface of the tablet or plate a. I provide a ring or flange b.
having a circular path c. which can freely revolve within a circular opening in the
tablet or plate a.
The said ring or flange is provided with lugs g. into which are placed guides,
studs or rollers f. for the purpose of preventing the tablet or plate from working off
the path c
I employ four or more set screws such as h. for the purpose of adjusting
and retaining the ring or flange b. in a position concentric to the wheel.
I attach the said ring or flange b by bolts or studs e. which pass between the
spokes n. of the wheel and are retained by suitable washer plates j. and nuts k.
The plate or tablet a. is provided with a weight I which tends to retain it in a
nearly vertical position whilst the wheel is revolving, so that the advertisement
can be properly read when the vehicle is travelling.
Referring to Figs. 3, 4, 5, 6, & 7, of the drawings, when the advertisement is
formed by perforated letters or devices I attach a plate or tablet a¹ so that it can
revolve with the wheel and I cut or form the necessary letters or devices in the
front tablet or plate a.
The back plate a¹ is attached by suitable rivets or bolts a¹¹ to the ring or flange b.
This plate or tablet can be painted in two or more colours.
In the drawings (Figs. 4 & 5) c. may represent white and y. red.
As the wheel revolves the plate a' revolves with it whilst the perforated plate a.
remains in a comparatively stationary position. The red and white colours are
consequently alternately seen through the letters or devices and produce an optical
effect to attract attention to the advertisement.
Instead of carrying the loose plate or tablet a. by a ring or flange, I sometimes
employ rollers such as shewn in Figs. 8 & 9.
In this case suitable clips m. are attached to the spokes of the wheel by bolts or
studs p. To these bolts is fixed the back plate a.
Upon the outer end of the bolts I employ rollers such as q. which support the
front plate a. The said rollers and the plate a' revolve with the wheel whilst the
plate a. is held in a comparatively stationary position by the action of the weight 1.
before referred to.
In some cases I dispense with the rollers and employ studs or projections r.
attached to the fixed plate a' and which support the loose plate a as shewn in
Figs. 10 & 11 of the drawings.
It will be obvious that instead of employing a weight such as 1. the tablet or plate a.
might be made of a form or shape to give a preponderance of weight at the lower
part, for the same purpose and that in some cases the tablet or plate a. might be
retained in a comparatively stationary position by a cord, rod, or other equivalent,
attached to the body or other part of the vehicle.
I would have it observed that my improved advertising device or apparatus is
carried by the wheel itself and is quite independent of the axle so that if required

page_text: the wheel with the apparatus thereto can be removed from its axle in the ordinary
manner.
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. In an advertising device or apparatus the use in connexion with the wheel
of a vehicle of a tablet or plate carried by an attachment to the wheel and which
notwithstanding the revolution of the wheel does not revolve therewith substantially
as described.
2nd. In an advertising device or apparatus applied to the wheel of a vehicle the
combination of two tablets or plates, the one being attached to and revolving with
the wheel, the other not revolving therewith the latter having perforated letters or
devices through which portions of the former are visible substantially as described
for the purpose set forth.
