Year: 1872

page_text: LETTERS PATENT John Rendall and William Rendall, both of Stoke
Newington, in the County of Middlesex, Wheelwrights and Con-
tractors and Co-partners, for the Invention of "CERTAIN IMPROVEMENTS
IN SLOP CARTS EMPLOYED FOR COLLECTING SEWAGE AND STREET REFUSE AND
Sealed the 13th June 1873, and dated the 16th December 1872.
PROVISIONAL SPECIFICATION left by the said John Rendall and
William Rendall at the Office of the Commissioners of Patents,
with their Petition, on the 16th December 1872.
We, JOHN RENDALL and WILLIAM RENDALL, both of Stoke
Newington, in the County of Middlesex, Wheelwrights and Contractors
and Co-partners, do hereby declare the nature of our said Invention
for "CERTAIN IMPROVEMENTS IN 'SLOP CARTS' EMPLOYED FOR COLLECTING SEWAGE
AND STREET REFUSE AND CARRYING EARTH AND MANURE," to be as follows:-
•
-
The Invention relates more particularly to that class of cart known
as "slop cart," which is a vehicle employed by scavengers to contain

page_text: the mud, sludge, or sewage collected from the streets or thoroughfares
of cities or large towns, and is designed for the purpose of enabling such
carts when full to be "tipped" or to have their load discharged with
ease and facility, and after which to become again readjusted and locked
in position for re-use.
The improvements consists in supporting and connecting the tail board
of the cart by means of radial arms to centres or fulcra placed imme-
diately above the wheel axle on either side of the cart. These said arms
form continuations of the cart shafts, and are so arranged, with reference
to the cart or box containing the mud or other material, that the bearing
centres of the load upon the springs will be just over the supporting axle
or centre of gravity.
The hind or rear part of the cart forming the junction or seating for
the tail board partakes of the segment of a circle, agreeing with the
radia described by the lever supporting the same. Stop pieces or rests
projecting from the back base of the cart are provided for the purpose
of retaining, in conjunction with a lever lock and spring at the front of
'the cart the same in its parallel normal position. Thus when the cart
or box is being filled or full the tail piece closing in and forming the
rear end or back of the cart is in close contact with its segmental
terminations, but immediately it is desired that the load should be
discharged the front lever lock is unfastened and the cart heeled or
tilted over without any reference to the "tail piece," as this portion
being supported by the radial arms forming a portion of the cart shafts
remains undisturbed and in its normal position. The angular position
of the cart when being tilted slides from its mud retaining tail board
and thus allows the contents of the cart to be readily discharged. On
readjusting the cart on its seatings upon the shafts its terminal segments
slide up the corresponding concave segmental portion of the tail piece,
and so effectually by self-acting means close in the end or tail of the
cart preparatory to its again receiving the scavengings from the
streets.

filed by the said John Rendall and William Rendall in the Great
Seal Patent Office on the 16th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
RENDALL and WILLIAM RENDALL, both of Stoke Newington, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Rendall and William
Rendall, Her special license that we, the said John Rendall and
William Rendall, our executors, administrators, and assigns, or such
others as we, the said John Rendall and William Rendall, our exe-
cutors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN 'SLOP CARTS' EMPLOYED FOR COLLECTING SEWAGE AND STREET REFUSE
AND CARRYING EARTH AND MANURE," upon the condition (amongst others)
that we, the said John Rendall and William Rendall, our executors or
administrators, by an instrument in writing under our, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW {KNOW YE, that we, the said John Rendall and William
Rendall, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to
say:

page_text: the mud, sludge, or sewage collected from the streets or thoroughfares
of cities or large towns, and is designed for the purpose of enabling such
carts when full to be tipped or to have their load discharged with ease
and facility, and after which to become again readjusted and locked in
position for re-use.
The improvements consist in supporting and connecting the tail board
of the cart by means of radial arms to centres or fulcrâ placed imme-
diately above the wheel axle on either side of the cart. These said arms
form continuations of the cart shafts, and are so arranged, with reference
to the cart or box containing the mud or other material, that the bearing
centres of the load upon the springs will be just over the supporting axle
or centre of gravity.
The hind or rear part of the cart forming the junction or seating for
the tail board partakes of the segment of a circle, agreeing with the
radia described by the lever supporting the same. Stop pieces or rests
projecting from the back base of the cart are provided for the purpose
of retaining, in conjunction with a lever lock and spring at the front of
the cart, the same in its parallel normal position. Thus when the cart
or box is being filled or full the tail piece closing in and forming the
rear end or back of the cart is in close contact with its segmental
terminations, but immediately it is desired that the load should be
discharged the front lever lock is unfastened and the cart heeled or
tilted over without any reference to the "tail piece," as this portion
being supported by the radial arms forming a portion of the cart shafts
remains undisturbed and in its normal position. The angular position
of the cart when being tilted slides from its mud retaining tailboard
and thus allows the contents of the cart to be readily discharged. On
readjusting the cart on its seatings upon the shafts its terminal segments
slide up the corresponding concave segmental portion of the tail piece,
and so effectually by self-acting means close in the end or tail of the
cart preparatory to its again receiving the scavengings from the
streets.
In order that the Invention may be better understood and explained
in detail, we have hereunto attached a Sheet of Drawing, made upon
a scale of about one inch to the foot, letters of reference being marked
thewounon

page_text: DESCRIPTION OF DRAWING.
Figure 1 represents a front elevation of the slop cart in the position
it would assume when being filled with slop or other material. The
"dotted lines represent the position of the cart when tilted or at the time
of discharging its contents. In this view a, a, is the body of the cart
supported through the medium of the spring 6 on the axle c of the cart
wheels. Immediately above the axle c and fixed to the cart on either
side thereof is a projecting stud d, which form fulcra for the arms or
lever e, which are portions or continuation of the cart shafts f. To the
extremity of these arms or levers the tail board g of the cart is fixed.
The junction between the tail board g and the rear sides of the cart a
partakes of the form of a segment corresponding with the radia described
from the fulcra or center d. Stop pieces i, i, are provided that come in
contact with the base of the tail board when the cart is in position for
receiving slop or mud.
The action of tilting or discharging the load and the self-adjustment
of the several parts will readily be understood by the following
description, reference being had to the foregoing:-When the cart or
box a is being filled or full the tail piece or board g, closing in and
forming the rear end or back of the cart a, is in close contact with its
segmental terminations, but immediately it is desired that the load
should be discharged the front lever lock is unfastened and the cart
heeled or tilted over into the position shewn in dots, without any
reference to the tail piece 9, as this portion being supported by the
radial arms e forming a portion of the cart shafts ƒ remains undisturbed
and in its normal position. The angular position of the cart when
being tilted slides from its mud rėtaining tail board g and thus allows
the contents of the cart to be readily discharged. At the time of tilting
and discharging a portion of the tail board g¹ is drawn up by the chain k
into the position shewn in dots, and so forms a splash board.
On re-
adjusting the cart on its seatings upon the shafts fits terminal segments
slide up the corresponding concave segmental portion of the tail piece g,
and so effectually by self-acting means close in the end or tail of the
cart preparatory to its again receiving the scavengings from the streets.
Having now described the nature of our said Invention, together with
the method of carrying the same into practical effect, we would wish it

page_text: to be particularly understood in conclusion that we claim the novel and
peculiar arrangement, construction, and adaptation to carts employed
for carrying loads that require to be readily discharged of their contents
of the parts marked e and g to be employed for the purpose, and in the
manner substantially described, set forth, and fully illustrated in the
Drawing attached.
Drawing attached.
In witness whereof, we have hereunto set our hands and seals, this
Thirteenth day of June, in the year of our Lord One thousand
eight hundred and seventy-three.
