Civil Engineer do hereby declare the nature of my invention for A NEW
SCAVENGER'S CART and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement :-
:
First See Drawing: Fig 1 represents the end elevation of the Cart:
:
Fig 2 a
longitudinal Section: Fig 3 a transverse Section Fig 4 a Sectional plan at A:-
B represents the inner Chamber in the Cart corrugated at the sides as shown and
provided with three tubes C, C, C, the Chamber B is supported above the bottom
of the outer Chamber or Cart D leaving the space E, and this space is cut off from.
the space E which passes all round the Cart except at the top: between the tubes
C, C, C, and resting upon the angle irons attached thereto are the perforated
plates F, F, F, a door G is provided.
Upon the top of the cart supported by the frame H shown is provided a gas bag
which is to supply gas (under pressure) to the pipes J through the mains K such
pipes being attached only to the chamber B: Air pipes L are provided leading to
the external air with entrances properly protected from the weather: draft openings
are to be provided on top as required.
The gas bag is to be supplied through a flexable pipe connected for the purpose
from a Street Main.
M is an endless string of buckets capable of being revolved upon the drums N
and worked by the strap or chain 0 passing over the spur P and attached to the
cart wheel and working only as the cart moves (a loose pulley may be provided
that the latter may work without the foriner if desired).
Qare screw bolts supporting the spindle of the drum N and capable of adjusting
the height of the brackets by regulating the length of the chain or strap. O and by
the nuts R: these nuts although not shown sufficiently upon the drawing should
have been farther from the spindle when in its working position, and arms fixed.
upon both of the nuts R and R* as shown at R* to facilitate adjusting the heights
of the buckets M, M.
Upon the lips of the buckets M are secured strips of rubber or leather, or hairs
forming small longitudinal brushes.
The spindle of the lower drum N' is free to rise or fall and works in the channel
iron guides S. T is the hopper to catch the snow from the buckets after being
raised. T being the shoot leading into the cart this is to be covered in from the

page_text: hopper. U is the supply arm from the space E provided with proper valve and
worked by lever from the ground. U is a perforated pipe. V is a stop cock of
large dimensions.
The outer Chamber or Cart D is closed in on top and it is provided with a
door W. It is intended by means of two screws to lower the front part of the Cart
upon the axle when desired.
The working is performed as follows:-
When ready, through door W light the gas, and the buckets M being adjusted to
take the snow only (if it is desired to water the roads with the snow water) upon
the Cart being drawn in the direction of the arrow, motion is given to the buckets,
the snow tipped into the hopper T and by T into the chamber B, it is there melted
and passes through the perforated plates F, F, into the space E thence through U to
U2 and over the roads: should it not be desired to water the roads keep the valve
at U closed and take the Cart full to the nearest drain or where desired and open
the stop tap V or the doors.
"
Second For the general use of the Cart to pick up the mud and dust from
the roads, the gas bag & frame H should be taken off by the hooks provided, the
top of the Cart should then be taken off, after the protection against the weather
of the entrances to the air pipes L have been removed: the inner chamber B should
then be lifted out by means of the hooks provided after the door G has been
secured, and then the top refixed.
The picking up and filling the Cart will then be similar to the foregoing Case
No. 1; when filled take to the scavengers heaps for emptying. Should the snow
chamber B be in place and mud &c required to be picked up temporary solid plates
in lieu of the perforated ones at F may be fixed and the whole process carried on as
above.
Third For watering the roadways: the Cart being as left for the purposes
secondly mentioned. Should it be desired the buckets and hopper &e may be
removed altogether by unscrewing them from the body D of the Cart, it will, then
be a complete watering cart only, after making good the apertures with plates
provided.
Rubber, leather or hardwood bearings are to be fixed upon the drums N where
the bucket chains are carried.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is
First The form and arrangement as shown upon the drawing of a snow melting
Chamber inside a Cart and being enabled to remove the same and use the outer
Cart as a pick up for mud, or as a watering Cart substantially as described. ..
Second-Buckets fixed as shown upon the drawing and capable of being revolved
by the motion of the wheels of the Cart, regulated to any beight and capable of
scraping up and raising snow, mud &c into the Cart, or inner Chamber as required,
the buckets having rubber, brushes, or leather secured upon the lips of them
substantially as described. .
