Improvements in or connected with Vehicles, particularly Designed
for Advertising Purposes.
I, EMILE HENRY TOWN END, of 20, Parkfield Avenue, Bradford Moor, Bradford.
Yorkshire, Gentleman, do hereby declare the nature of this invention to be
as follows:
an
This invention relates to improvements in or connected with vehicles, par-
ticularly designed for advertising purposes, the object being to furnish
ordinary travelling vehicle with the necessary mechanism for causing a series
of pictorial or other advertisements, announcements, or the like, to be dis-
played upon the back or sides or other convenient part of the vehicle, while it is
travelling, the length of time that each advertisement appears, depending
upon the arrangement of the mechanism, and the speed at which the vehicle is
travelling.
The advertisements, announcements or the like to be displayed, are mounted
upon an endless band or endless bands operated by chains and chain wheels
in the ordinary manner, this invention referring more particularly to the
mechanism employed to operate the driving shaft and to the general arrange-
ment of such mechanism in connection with a travelling vehicle.
In carrying this invention into practical effect, a chain wheel is mounted
upon the hub of one of the running wheels of the vehicle and connected by a
chain to a second wheel mounted upon a pin or axle arranged within the vehicle,
and carrying at its extremity a second toothed wheel connected by means of
a chain to the driving axle in such a manner that the said driving axle may
be periodically revolved.
To this end, the chain passes over a loose chain wheel mounted on the driving
axle, upon each side of which and in close proximity thereto is arranged a
fixed toothed wheel or its equivalent. A sufficient part of the chain carries
pins or studs projecting at each side thereof and designed, as the chain passes,
to engage the said fixed wheels, causing the driving axle to make one or more
revolutions as required, the said driving axle, making no further revolution
until the chain has completed its revolution and the pins are again brought
into contact with the fixed wheels.
In this manner, as the vehicle travels, the driving axle is periodically revolved,
causing the advertisements. announcements, or the like to be brought before
suitable openings in the sides of the vehicle, or they may be arranged in any
other convenient manner, the driving axle directly operating one series of
advertisements while the other series are operated through bevel gear connections
or other suitable connections.

I, EMILE HENRY TOWNEND, of 20, l'arkfield Avenue, Bradford Moor, Bradford,
Yorkshire, Gentleman, 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 improvements in or connected with vehicles par-
ticularly designed for advertising purposes, the object being to furnish an
ordinary travelling vehicle with the necessary mechanism for causing a series
of pictorial, or other advertisements, announcements, or the like, to be dis-
played upon the back, sides, or other convenient part of the vehicle, while it is
travelling, the length of time that each advertisement appears, depending
upon the arrangement of the mechanism, and the speed at which the vehicle is
travelling.
The advertisements, announcements or the like to be displayed, are mounted
upon an endless band or endless bands operated by chains and chain wheels
in the ordinary manner, this invention referring more particularly to the
mechanism employed to operate the driving shaft and to the general arrange-
ment of such mechanism. in connection with a travelling vehicle.
In carrying this invention into practical effect, a chain wheel is mounted
upon the hub of one of the running wheels of the vehicle and connected by a
chain to a second wheel mounted upon a pin or axle arranged on the vehicle
and carrying a second toothed wheel connected by means of a chain to the
driving axle in such a manner that the said driving axle may be periodically
revolved.
To this end, the chain passes over a loose chain wheel mounted on the driving
axle, upon each side of which and in close proximity thereto, is arranged a
fixed toothed wheel or its equivalent. A sufficient part of the chain carries
pins or studs projecting at each side thereof and designed, as the chain passes.
to engage the said fixed wheels, causing the driving axle to make one or more
revolutions as required, the said driving axle making no further revolution
until the chain has completed its revolution and the pins are again brought
into contact with the fixed wheels, or as an alternative arrangement two loose
chain wheels may be mounted side by side upon the driving axle, and operated
by a twin chain, while between them a fixed chain wheel is mounted upon the
driving axle. The two driving chains are united at any suitable point by one,
two or more connecting bars, which are brought into contact with the fixed
wheel mounted upon the driving shaft once in one complete circuit of the twin
driving chain so as to revolve the fixed wheel and driving axle, and in this
manner, as the vehicle travels, the driving axle is periodically revolved, causing
the advertisements, announcements, or the like to be brought before suitable
openings in the sides of the vehicles.
In order that this invention may be more fully understood I will now proceed
to describe same with reference to the accompanying drawings, in which :-
Fig. 1 is a side elevation of the operating mechanism.
Fig. 2 a rear elevation of same.
Fig. 3 a side elevation of the completed vehicle.
Fig. 4 a detailed view illustrating the method of securing the posters or the
like to the chains, and
Fig. 5 illustrates an alternative arrangement for periodically operating the
driving axle.

page_text: According to this invention and as shewn in the accompanying drawings, to
the hub a of the running wheel a', a toothed wheel b is fixed, gearing by means
of an endless chain b with the toothed wheel 62 which is loosely mounted on
the shaft c, connection between the shaft and the chain wheel being made
by means of ratchet c¹ so that the shaft c is only revolved in a forward direction,
and to this shaft two chain wheels dd are rigidly secured, gearing by means
of an endless twin chain furnished with cross or uniting bars, with two
loose wheels carried by the driving axle e, and between the two loose
wheels a fixed toothed wheel f is arranged so that as the twin chain d
revolves, the cross or uniting bars are periodically brought into contact with
the fixed wheel f, thereby sufficiently revolving the driving axle e, or to this
and as shewn in Fig. 5, a single chain fl may be employed passing over a
loose wheel mounted on the driving axle e, while on each side of the loose
wheel a fixed wheel f³ is mounted, and the chain fl carries at each side
a sufficient number of projecting pins or studs f which are periodically brought
into engagement with the fixed wheels f³f for sufficiently revolving the driving
axle e.
The driving axle e carries at each end a bevel wheel g gearing with smaller
bevel wheels g carried by the lower pair of horizontal shafts and in such
a manner as to turn the endless chains h and h¹ passing over the fixed chain
wheels mounted upon the horizontal shafts j¹, and over the loose chain
wheels suitably mounted upon the frame-work of the machine, the lower
pairs of chain wheels being preferably adjustably mounted' in slots formed in
the uprights to allow of the necessary adjustment of the chains being effected.
The endless and duplicate pairs of chains h¹ are provided with projecting
lugs to support the wooden laths to which the posters are attached and as
shewn in Fig. 4, the top and bottom laths are fixed to the poster itself and
only require to be screwed to the metal lugs at the four corners the inter-
mediate laths being practically fixtures and against which the posters or the
like bear.
The size of the driving wheels and the twin chain d' are proportionately
arranged so that with each complete circuit of the twin chain or the alter-
native single chain f¹ (Fig. 5), the driving axle e is sufficiently revolved for
bringing a fresh poster or advertisement sheet accurately in position at each
side of the vehicle in the space F.
To prevent the posters shifting out of position by the vibration of the vehicle
a suitable ratchet wheel may be mounted upon the driving axle e.
In cases where horse or motor power is to be used, the vehicle would he
built proportionately larger and an additional shafts, operated through bevel
wheels as indicated in dotted lines (Fig. 1), may be employed to revolve chains
carrying posters designed to be brought into view at the back of the vehicle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In vehicles more particularly intended for advertising purposes, the general
combination and arrangement of the parts constituting the operating mechanism
for bringing into view at the sides and end of the vehicle, one at a time and
for any required period, a series of posters, pictorial, or other advertisements,
announcements or the like, substantially as herein described and shewn with
reference to the accompanying drawings.
2. In a vehicle more particularly intended for advertising purposes, the arrange-
ment of two pairs of endless chains such as h h passing over chain wheels such
as and carrying posters or pictorial or other advertisements, and the like
and designed to be periodically partially revolved for bringing fresh advertise-
ments into view by means of suitable bevel wheel gearing or the like carried
by a driving axle such as which is periodically sufficiently revolved by means
:

a shaft such as c operated so as to be caused to revolve by a chain and chain
wheels arranged in connection with one of the running wheels of the vehicle,
and passing over loose chain wheels such as mounted upon the driving axle e,
and periodically revolving a fixed chain wheel such as f mounted upon the
driving axle e by cross or uniting bars such as 2, the whole combined and
arranged substantially as herein described and shewn and for the purposes
specified.
3. The alternative form of mechanism for periodically revolving the driving
axle e, substantially as herein described and shewn with reference to Fig. 5
