PROVISIONAL SPECIFICATION.
Improved Circular Elevator, adapted for use with Various Vehicles,
Street Sweeping Machines, or the like, whereby Mud, Earth,
Sand, Stones, Turnips, Beet, or other Roots and Substances may
be Raised from the Ground and Placed into Hoppers, Carts,
Wagons, or other Vehicles.
I, WILLIAM JAMES BURGESS, of Wiggenhall St. Mary Magdalen, near Lynn,
Norfolk, Farmer and Auctioneer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide carts, wagons or other vehicles with
apparatus whereby they may be filled from the ground as they travel along.
The invention consists of a revolving circular elevating wheel the outer portion
of which rests upon the ground and may support the weight of that side of the
vehicle to which it is attached, the inner side of this wheel is provided with cups
or pockets, into which any roots, earth, sand &c. may be ploughed or thrown, or
otherwise caused to pass, or any liquid or loose substances may be brushed or
scraped or otherwise caused to pass, when at the ground level, and such
substances are carried upwards by the revolution of the elevating wheel until
they nearly reach the top, when as the cups or pockets become inverted, their
contents are dropped out into an inclined trough or hopper formed on the side
of the vehicle, which conducts these falling substances into the said vehicle.
The cups or pockets are formed so as to offer no resistance to the substances
passing into them, and are sloped so as to pass the substances into the deeper
side and retain them until they are poured out by the reversal of the cups by
the travel of the wheel.
This elevating wheel when it is to be used for lifting turnips, beet, mangel, or
such roots into a cart or other vehicle, may be formed of bars or rods, with
spaces between, which will allow the loose mould to fall away from the roots
as they are carried upwards, and when it is to be used for lifting earth, sand,
mud, small stones or such substances, it may be constructed of sheet metal, or
of any suitable substance, without the spaces or interstices between, so as to
prevent the substances from falling through as they are lifted.
When used in connection with a street sweeping machine for elevating the
mud or other street sweepings into the hopper of the vehicle, there may be
attached to the inner side of the elevating wheel, a flexible ring of india-rubber,
leather, steel or any suitable material with a thin edge, and this ring being
tapered outwards somewhat larger than the elevating wheel, will form a flat
surface on the ground as the wheel revolves, and across this flattened surface,
the sweepings may be brushed quite into the cups or pockets of the elevator.
In all cases the wheel is preferably closed up so as to prevent the mud or
other substances from being thrust right through the elevator, and a curved
shield or guard may be so placed near to the cups on the inner side of the wheel
as to prevent the mud from splashing out, or the other substances from falling out
until they reach the trough prepared to receive them, this guard being so inclined
that anything falling out of the cups (before they reach the trough) will be passed
into the cups following, and thus ensure their being brought into the trough which
conveys them in to the vehicle.

Improved Circular Elevator, adapted for use with Various Vehicles,
Street Sweeping Machines, or the like, whereby Mud, Earth,
Sand, Stones, Turnips, Beet, or other Roots and Substances may
be Raised from the Ground and Placed into Hoppers, Carts,
Wagons, or other Vehicles.
I, WILLIAM JAMES BURGESS, of Wiggenhall St. Mary Magdalen, near Lynn,
Norfolk, Auctioneer and Farmer 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:-
The object of my invention is to provide an improved circular elevator adapted
for use with various vehicles, street sweeping machines or the like whereby mud,
earth, sand, stones, turnips, beet or other roots and substances may be raised from
the ground and placed into hoppers carts wagons or other vehicles.
The invention consists of a revolving elevating wheel, which is caused to travel
along the ground and may support one side of the vehicle to which it is attached.
This wheel is provided at the inner side of its periphery with a series of sloping
cups or pockets, into which street sweepings or any loose or liquid materials may
be brushed and earth or sand, stones, beet, turnips or other substances may be
ploughed thrust or otherwise deposited, at that part of the circumference which
rests upon the ground, and as the wheel revolves these substances are carried
upwards, until as they arrive near the top of the wheel they are poured from the
cups on to an inclined surface which is placed so as to conduct them into the
hopper or body of the vehicle to which the wheel is attached.
When this elevator is used in connection with the ordinary street sweeping
machine, the main frame of the machine is. lengthened by any suitable means at
the hinder part and on this frame is placed the hopper which is intended to receive
the street sweepings when raised, beneath this hopper is placed the axle which
carries the road wheels and on one end of this axle is placed one of the road wheels
which is ordinarily used with these machines and at the other end of this axle
which is preferably cranked upwards to receive the larger diameter is placed the
elevator wheel which is intended to receive and elevate the street sweepings. The
axle is placed in such a position in relation to the revolving brushes, that the street
sweepings are brushed into the cups of the elevator wheel at the part which rests
upon the ground. The wheel is formed at its inner circumference with a tapering
ring of steel, india rubber or any suitably flexible material, which as it rests upon
the ground, flattens out to receive the materials being brushed into the cups, as the
wheel revolves these materials are carried upwards until as the cups or pockets are
gradually turned mouth downwards the sweepings are poured out on to the inclined
surface placed to receive them and convey them into the hopper. The outer side
and the periphery of the elevator wheel are preferably formed without any
openings so that the materials swept in may all be received into the elevator cups
or pockets. When used, however, for the purpose of lifting roots or other
substances with earth attached, part of the periphery of the wheel will then be
preferably formed with suitable openings through which the loose earth may fall or be
thrust as much as possible, the roots alone falling and remaining in the elevator
cups. Attached to the hopper or frame, from the lower part, a guide passes
upwards, close to the side of the cups, as high as the point where the cups by being
reversed would empty their contents on to the inclined surface, this guide is placed
to retain the materials within the cups until they have reached a suitable height to
be emptied out. In the connection of my elevating apparatus to an ordinary street
sweeping machine, I attach to the inner end of the hob of the elevator wheel a
chain wheel which is connected by a chain or other suitable gearing with the
original axle of the sweeper, a similar chain may be attached to the other side
wheel it necessary, each chain wheel being proportioned to the diameter of the

page_text: road wheel to which it is attached, whilst a pawl and ratchet arrangement in each
wheel will allow the machine to be turned about without friction this being the
arrangement commonly used for that purpose, from the original axle of the sweeper,
thus driven, motion may be coinmunicated to the revolving brush by means of the
ordinary gearing used for that purpose.
And in order that my said invention may be fully understood, I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Fig. 1 represents in plan so much of an ordinary street sweeping machine as is
sufficient to illustrate my invention, shewing the attachment of the elevator, and
the method of communicating motion to the brush.
Fig. 2 represents a side elevation of the same arrangement, the elevating wheel
being in section to shew the positions of the elevating cups or buckets.
Fig. 3 is an end elevation of the same and
Fig. 4 an end elevation of an ordinary cart shewing the elevating wheel, and the
plough beneath the cart, which may be of any form suitable for placing roots,
stones, earth or other materials into the cups or pockets of the elevating wheel.
A is the frame of an ordinary street sweeping machine, lengthened backwards to
receive the hopper or receptacle B. C is the axle which is attached to the frame A,
by the usual or any suitable bearings. D is the ordinary road wheel of a street
sweeper mounted as usual on one end of the axle. E is the elevating wheel of
suitably larger diameter mounted upon the opposite end of the axle, which is
cranked upwards at F to receive it. G G are the elevating cups or pockets. H is
the guard placed alongside the cups to prevent their contents from falling out
sidewise before they arrive at the proper height. J is the inclined plane placed
to receive the contents of the elevating cups and convey them into the hopper or
receptacle B. K K' are the chain wheels on the inner ends of the hobs or naves
of the road wheels connected by the chains L L' to the corresponding chain
wheels M M on the axle or shaft N which by the usual train of gearing
communicates the necessary revolutions to the brush O. When using my circular
elevator for the purpose of raising roots, as beet turnips, potatoes or the like the
hopper or receptacle B with the axle and wheels attached as before described may
be placed above, and attached to any suitable plough or digging machine of ordinary
construction and use in such a manner that the roots or other substances will be
passed by the plough or digging machine into the elevating cups or pockets. A
modified form of this plough being also used for passing earth sand or any similar
materials into the cups or pockets of the elevator wheel.
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 :-
1. The combination and use of a circular rotatory elevating wheel or wheels, for
the purpose of receiving, elevating and depositing into suitable receptacles the
refuse sweepings from the brushes of ordinary street sweeping machines substantially
as hereinbefore described.
2. The combination and use of a circular rotatory elevating wheel or wheels for
the purpose of receiving elevating and collecting into suitable vehicles or hoppers
roots as beet, turnips potatoes &c. substantially as hereinbefore described.
3. The combination and use of a circular rotatory elevating wheel or wheels for
the purpose of receiving elevating and collecting into suitable vehicles or hoppers
earth, stones, mud, sand or similar materials substantially as hereinbefore described.
