AN IMPROVED VAN FOR ADVERTISING PURPOSES
Year: 1885

page_text: We WILLIAM THOMAS BEAUMONT of 11 Lansdowne Road, and THOMAS GRIME
of 251 Middleton Road, both of Oldham in the County of Lancaster Mercantile
Clerks do hereby declare the nature of our invention for "AN IMPROVED VAN FOR
ADVERTISING PURPOSES" to be as follows:—
This invention relates to vans employed for advertising purposes the object of
the invention being so to construct the van as to contain a large quantity of
different advertisements, a certain number of which only are displayed at one time
and are changed intermittently as the van is drawn along.
The van may be made with either two or four wheels, one wheel being keyed or
otherwise fixed fast upon its axle which is so mounted so to be capable of revolving
with the same: the other wheel or wheels may be loose.
Upon the revolving axle is keyed a stud wheel driving (by means of an endless
chain) a second stud wheel mounted upon a shaft or axle inside the body of the
cart; a clutch box being provided by means of which the stud wheel can be con-
nected to or disconnected from its shaft as required. This shaft is provided with
bevil or other toothed gearing by means of which it can drive vertical rollers
placed at each corner of the van. The body of the van is made of frame work
with open panels, inside which an endless canvas is stretched round the vertical
rollers, passing round the two sides and the back, and backwards and forwards
from front to back inside, round other guide rollers, so that the length of the
canvas will be several times that of the van. Upon this endless canvas the various
advertisements are printed or painted and are seen through the open panels of
the van.
The driver of the van may be provided with a lever or treadle by means of
which he can throw the clutch box into gear at intervals so as to cause the vertical
rollers to revolve and change the advertisements which are visible through the open
panels, but we prefer to make this movement automatic by means of a cam
mounted on or connected to the revolving axle in such a way that at every certain
number of revolutions as may be desired the cam shall throw the clutch box into
gear and thus cause the vertical rollers to make a sufficient number of revolutions
(or a sufficient portion of a revolution) to display a fresh set of advertisements
through the open panels at the sides and back of the van.

of 251 Middleton Road both of Oldham in the County of Lancaster Mercantile
Clerks do hereby declare the nature of our invention for AN IMPROVED VAN FOR
ADVERTISING PURPOSES 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 vans employed for advertising purposes, the object of
the invention being so to construct the van as to contain a large quantity of
different advertisements, a certain number of which only are displayed to view at
one time, and changed intermittently as the van is drawn along.
The nature and object of our said Invention will be readily understood on 1
reference to the annexed sheet of drawings which are marked with figures and
letters of reference corresponding with those in the following explanation thereof.
Fig. 1 is a side elevation of the exterior of our improved advertising van.
Fig. 2 is a back view, and Fig. 3 a horizontal section or plan view of the same.
The van a, a may be made with either two or four wheels b, b (four being shown 1
on the drawing) and one of these may be keyed fast upon its axle which in that
case would be so mounted as to be capable of revolving with the same.
We prefer however to have the axles fixed and all the wheels loose.
Upon the boss of one of the wheels marked b¹ (or upon the revolving axle when
used) a stud wheel c, c is fixed driving by means of an endless chain d, d a second
stud wheel e, e mounted upon a shaft or axle fif at the rear end of the van or
inside the body thereof. A clutch may be attached to the stud wheel e, e so as to
connect or disconnect it with its shaft as required.
We prefer however to make the shaft in two parts ƒ, and ƒ¹ and to connect these
together by a clutch box g, g'.
At the opposite end of the shaft to the stud wheel e, e is keyed a bevil wheel
(see Fig. 2) driving a similar wheel fixed on the axle of one of a series of vertical
rollers h, h placed at each corner of the van.
The body of the van is made of frame-work a, a with open panels inside which
an endless canvas i, i is stretched round the vertical rollers h, h passing round the
two sides and the back, and backwards and forwards from front to back inside
(see Fig. 3) round other guide rollers ke, k so that the length of the canvas i, i will
be several times that of the van.
Upon this endless canvas i, i the various advertisements are printed or painted
The
and are seen through the open panels at the sides and back of the van.
roller is made movable to increase or diminish the tension of the canvas i, i
when required.
The driver of the van may be provided with a lever or treadle (not shown on
the drawing) by means of 'which he can throw the clutch box g, g¹ into gear at
intervals so as to cause the vertical rollers h, h to revolve and change the advertise-
ments which are visible through the open panels, but we prefer to make this
movement automatic by means of a cam mounted on or connected to the driving
wheel b¹ or by other suitable means in such a way that after every certain number

page_text: of revolutions with one set of advertisements displayed as may be desired, the
cam shall throw the clutch box g, g¹ into gear and thus cause the vertical rollers
to make a sufficient number of revolutions to display a fresh set of advertisements
through the open panels at the sides and back of the van.
We prefer to form pegs or projections not shown on the drawings at the ends of
the rollers h and k and to form corresponding eyelets or holes in the edges of the
endless canvas so that the latter will not slip upon the said rollers.
The drawing shows the part g¹ of the clutch gear with a notch or depression
formed in its back surface.
This part g' is continually caused to revolve by the stud wheels cand e and the
chain & and is held in gear with the part 9 by a stud or projection on the fixed
bearing x.
But as soon as the depression in the part g¹ comes opposite to this stud or
projection, the spring y pulls back the part g¹ of the clutch from the part g and
the revolution of the rollers h is arrested until the depression on the back of the
part gl has passed clear of the projection, which then returns the part gl into gear
with the part g, and the revolution of the rollers and consequently the changing of
the advertisements re-commences.
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
The improved construction of van for advertising purposes having a frame-work
with open panels and provided inside the same with a number of rollers round
which passes an endless canvas upon which the advertisements are displayed, such
rollers (or one of them) being driven at intervals by a chain or other gearing from
one of the running wheels of the van, substantially in the manner and for the
purpose herein before particularly set forth and described.
