PROVISIONAL SPECIFICATION left by the said Edward Rayner at the Office
of the Commissioners of Patents on the 14th June 1882.
EDWARD RAYNER of Liverpool in the County of Lancaster Timber Merchant.
"IMPROVEMENTS IN AND APPLICABLE TO WHEELED VEHICLES FOR FACILITATING
THE UNLOADING OF TIMBER, METAL BARS AND OTHER LENGTHY ARTICLES
"
The object of my invention is so to construct or fit wheeled vehicles mainly
four wheeled wagons that deals, boards, baulks and logs of timber, pipes, rods, and
bars of metal and other articles of considerable length in timber metal or other
material may be easily and rapidly unloaded or removed when required from the
said vehicles or wagons.
My invention consists essentially in constructing or fitting the body of the vehicle
with two or more, preferably two rollers placed transversely at distances from each
other in an inclined plane from rear to front of the said vehicle. The rollers or
one or more of them is so arranged that immediately before and during the time of
unloading the timber or other articles are carried by the said rollers, which rollers
are free to rotate on their axes.
In one modification there are two rollers one free to revolve in bearings near the
front of the vehicle and the other carried in bearings near the rear end of the
vehicle. A transverse supporting piece free to turn on an axis and held in position
by studs or suitable catches is placed in front of or behind the rear roller.
The timber or other articles rest during conveyance or transit on the front edge
or board of the vehicle and on the transverse supporting piece. When it is desired
to unload or discharge the vehicle the transverse supporting piece is lowered until

page_text: the timber or load rests on the rollers the said timber or load is then free to move.
and is by the action of gravity caused to travel over the rollers and leave the
vehicle.
It will be obvious that excentrics cams and numerous devices may be employed
for retaining the load out of contact with the rollers or the rollers out of contact
with the load until the desired time. The positions of the rollers may be varied
care being taken that they are higher at the front than at the rear, or that they
should become so, as in the case of a two wheeled vehicle, by slightly raising the
front of such vehicle.
In another modification tho timber or other articles are borne by the rollers and
these latter are released when required. If necessary a friction band brake could
be used for lowering gently.

EDWARD RAYNER of Liverpool in the County of Lancaster, Timber Merchant
IMPROVEMENTS IN AND APPLICABLE TO WHEELED VEHICLES FOR FACILITATING

ور
The object of my invention is to so construct or fit wheeled vehicles mainly
four wheeled wagons that deals boards baulks and logs of timber, pipes rods and
bars of metal and other articles of considerable length in timber metal or other
material may be easily and rapidly unloaded or removed when required from the
said vehicles or wagons.
My invention consists essentially in constructing or fitting the body of the vehicle
with two or more, preferably two, rollers placed transversely, at distances from cach
other in an inclined plane from rear to front of the said vehicle. The rollers or
one or more of them is or are so arranged that immediately before and during the
time of unloading the timber or other articles are carried by the said rollers, which
rollers are free to rotate on their axes.
In one modification there are two rollers, one free to revolve in bearings near the
front of the vehicle and the other carried in bearings near the rear end of the
vehicle. A transverse supporting piece free to turn on an axis and held in position
by studs or suitable catches is placed in front of or behind the rear roller.
The timber or other articles rest during conveyance or transit on the front edge
or board of the vehicle and on the transverse supporting piece. When it is desired
to unload or discharge the vehicle the transverse supporting piece is lowered until
the timber or load rests on the rollers the said timber or load is then free to move
and is by the action of gravity caused to travel over the rollers and leave the
vehicle.
It will be obvious that eccentrics cams wedges and numerous devices may be
employed for retaining the load out of contact with the rollers, or the rollers out of
contact with the load until the desired time. The positions of the rollers may be
varied care being taken that they are higher at the front than at the rear or that
they should become so, as in the case of a two wheeled vehicle, by slightly raising
the front of such vehicle.
In another modification the timber or other articles are borne by the rollers and
these latter are released when required. If necessary a friction hand brake could
be used for lowering gently.
DESCRIPTION OF THE DRAWINGS
Fig 1 is a longitudinal section of a four wheeled cart constructed or fitted with
my improved means for discharging the load. a is the body of the cart, b front
edge or board c front roller free to revolve in bearings d. e back roller free to
revolve in bearings f. transverse supporting piece free to be turned on the axis h.
i studs or holding pins inserted through the side frame of the cart into the said
transverse supporting piece g so as to retain it in position the said piece may be
otherwise held. ; are boards carried by the said cart. When it is desired to
unload the cart the pins i are removed and the transverse supporting pieces g and
the boards are allowed to fall as shown by the dotted lines, the boards j then rest
on the rollers c. e. and are delivered by the action of gravity onto the ground.
Fig 2 is a transverse section and fig 3 a plan of a lorry adapted under my
invention for carrying and unloading timber rails pipes or like lengthy articles,
a body of lorry. b front edge or board hinged so as to turn down when not

lorry, horns or stay pieces passing through openings in the bottom of the lorry
and through clips attached to the board b. The said horns or stay pieces serve to
hold the load b upright and to prevent lateral motion of the timber or lengthy
articles being carried, c front roller working in bearings d. The bearings d are
secured to the plank m which latter is hinged so as to turn over when not required

bearing hinged at h, n quadrants attached to g. o notches, p sliding bolt, q bell crank
lever, connecting rod, s operating handle, spring to draw the bolt p into locking
position, the said spring may be dispensed with if desired or a weight may be used
instead. baulks of timber. The dotted lines show the timber being discharged.
It will be evident that when the parts b m. and g are folded down into the positions
shown by the dotted lines that the lorry will have a flat floor and may be used in
all respects as an ordinary lorry.
To discharge the timber all that is necessary is to pull the handle 8 withdraw the
locking bolt p and allow the transverse piece g to fall.
Fig 4 is a diagram of a cart or wagon body in which the transverse bearing g. is
a cylinder mounted excentrically and operated by a lever as shown by the dotted
lines.
Fig 5 is a diagram of a wagon body in which the two rollers cand e are
supported in sliding bearings and are raised by levers u as shown by the dotted
lines so as to lift the articles to be discharged free from bearing on the ends of the
said wagon body.
Fig 6 is a diagram of a wagon body in which the articles to be discharged are
carried on the rollers ce, the said rollers being prevented from turning by the
friction brakes v. The friction brakes are constructed and arranged in any
ordinary or desired manner, and to discharge the timber all that is necessary is to
release the brakes and allow the rollers to revolve freely. Any suitable means for
preventing the rollers from turning except when required such as pawls and ratchet
teeth may be used.
It will be evident that many modifications of my apparatus may be made and I
do not confine my invention to the details or arrangements described. It will be
evident that the combined rollers and retaining or releasing mechanism or apparatus
above described may be fitted or adapted to wagons and vehicles of any ordinary
construction.
Having now described and illustrated my said invention in such manner that
others will be enabled to carry my improvements into effect I claim:
First. The improvements in and applicable to wheeled vehicles substantially as
herein described for the purpose setforth.
Second. In wheeled vehicles the combination of rollers and retaining or releasing
mechanism or apparatus substantially as setforth for the purposo specified.
In Witness Whereof I the said Edward Rayner have hereunto set my hand,
and seal this
day of December in the year of Our Lord, one
thousand eight hundred and eighty two.
