I, HENRY SAMUEL TURNER, 3 Kensington Grove, Brierly Street, Nottingham,
Warehouseman, do hereby declare the nature of this invention to be as follows:-
I construct a van of suitable height and length provided on the underside with
two pair of wheels and springs, the front pair of wheels turn upon the outer ends
of an axle bar which is swivelled to the floor of the van to the front of which
shafts are attached and a covered seat for a driver, the floor of the van supports the
lower end of six vertical rollers, their upper ends being carried by the framing
which partly forms the roof, two of the rollers being within the van have the ends
of a length of canvas or other suitable material secured to them, the width of the
canvas or other material being about the height of the sides of the van is passed
round the other four rollers each of which revolves at one corner of the van.
The two rollers within the van are each provided at their lower end with a toothed
wheel in each of which a worm gears, the shaft or shafts of the worms are provided
with a clutch or clutches or it or their equivalent to throw either or both worms into
or out of gear with the clutch or clutches, by means of a lever or a series of levers
conveniently placed so as to be operated by the driver.
Each clutch or its equivalent is provided with a chain wheel, which is caused to
revolve by a chain passed round it, which also passes round a chain wheel secured
to one of the hind wheels of the van.
Such arrangement of parts enables the length of canvas to be alternately moved
off one roller onto the other roller at will, in passing from one roller to the other
the whole length of canvas or other material when covered with advertisements
will be alternately moved round the remaining four rollers of the van, along one
side, across the back, then along the other side, and reversed at will as the van is
drawn along. The sides and back of the van are provided with waterproof sheets
which can be let down over the advertising canvas when it rains, or the van is
at rest.

page_text: Figure 1 is a plan of an advertising van with the roof covering removed so as to
show the general arrangement of the roof framing and the relative position of six
canvas carrying rollers.
Figure 2 shows a longitudinal sectional view of the van and the relative positions
of a worm and chain wheel shaft, within the van and a chain wheel on the axle of
the hind wheels, beneath the floor of the van.
Figure 3 is an enlarged plan of part of the front flooring of the van showing the
relative position of the right front corner roller, and two rollers within the van upon
which the length of canvas is wound, together with the toothed gearing for revolving
them alternately.
Figure 4 shows a side view of the gearing and
Figure 4 a side view of the right rear wheel, chain driving wheel and a ratchet
wheel, severally referred to hereafter.
The corresponding parts in each Figure are indicated by the same letters where
necessary.
I construct each van of a suitable height and length and provide it on the underside
with two pair of wheels and springs of the usual construction the front pair of wheels
turn upon the outer ends of an axle bar which is swivelled to the floor of the van, and
provided at the front with lugs to which shafts may be bolted.
Above the floor at the front of the van a space is enclosed by boarding and
provided with a seat for a driver, the boarding at each end of the soat may be cut
away at a convenient height to allow of the insertion of panes of glass to enable
the driver to observe the winding and unwinding of the advertising canvas.
The floor of the van supports the lower end of six vertical rollers the axles of
which turn in metal bearing blocks A, four being let into blocks A' near each corner
of the van and two within the van being let into the floor, the upper ends of the
roller axles turn in bearings secured to the framing which partly forms the roof,
the rollers B within the van have the ends of a length of canvas D secured to them,
the width of the canvas being about the length of a roller is passed round the four
rollers Cat the corners, each roller at its lower end is provided with a flange to
support the lower edge of the canvas which is kept in position as it passes from
roller to roller by means of laths D¹ placed a suitable distance apart and stitched into
the canvas, the lower ends of the laths are shod with iron, and travel in either iron
troughs D at the sides and back end of the van or upon iron plates D³ shown only
at Figure 3.
The two rollers B are each provided at their lower end with a toothed wheel B¹
each alternately revolved so as to wind the advertising canvas upon it by the
following means:
Behind the toothed wheels three bearings are bolted to the floor of the van, in
which an axle shaft E revolves, provided near its outer end with a grooved wheel E¹

page_text: having studs which engage with the links of a chain E' shown at Figures 3 and 4,
the chain also passes round a grooved and studded wheel E³ which is free to revolve
upon the axle near the right rear wheel, the outer side of the wheel E carries a
toothed ratchet wheel E with which a driver E engages, being kept engaged by
a spring E which with the driver is attached to the inside of one of the spokes of
the right rear wheel, while so engaged the wheel E' will be revolved whenever the
van is drawn forward, the driver sliding over the ratchet teeth when the van is backed.
Near its inner end the shaft E carries a worm F which gears with a toothed
wheel F¹, secured to and revolving with a toothed wheel F" beneath it both turning
upon an axle bolted to the floor of the van, upon the same axle a bearing plate F³ is
free to turn carrying axle studs on which two toothed wheels F F revolve, the top
side of the bearing plate carries a stud which engages with a slot in the back end of
a right angled lever F which rocks upon an axle secured to the floor of the van, the
inner end of the lever is hinged to the back end of a rod which has its front end
hinged to a lever secured to one end of an axle bar rocking in bearings bolted to
the floor in front of the driver the right end of the bar being provided with a hand
lever F by which means when the hand lever is pushed by the driver towards the
front of the van, the wheel F will engage with the wheel F and the wheel B' at
the bottom of the right roller B causing that roller to be gradually revolved and
wind the advertising canvas upon it, but upon the lever F₁ being reversed by the
driver pulling towards him, the wheel F' will be disengaged from the wheel on the
right roller B remaining engaged with the wheel causing the intermediate
wheel F to engage with the wheel B' at the bottom of the left roller B.
When the hand lever is left in the position shown at Figures 3 and 4, the wheels B¹
of both rollers are disengaged to allow of the van being moved backwards or for
other purposes.
The length of canvas is kept tight by each of the rollers B being provided beneath
the lower flange with a friction pulley G shown at Figure 4, round each of these a
friction strap G¹ shown at Figures 3 and 4 is passed one end of the strap being
secured to a bolt projecting from the van floor and the other end to a spring
attached to the floor.
Such arrangement of parts operated as above described, enables the length of
advertising canvas to be alternately unwound off one roller and wound upon the
other roller at will, in passing from one roller to the other the length of canvas
covered with advertisements will be moved round the four corner rollers passing along
one side across the back, then along the other side and reversed at will as the van
is drawn along.
The sides and back of the van may be provided with waterproof sheets arranged
so that they can be let down over the advertising canvas when it rains or the van is
at rest.
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 :-
The construction and employment of improved advertising vans, substantially as
described and illustrated in the Drawings annexed.
Dated this Sixth day of June 1888.
