the 20th November 1868.
I, EDWARD HODSON BAYLEY, of 42, Newington Causeway, in the
Borough of Southwark, in the County of Surrey, Wheelwright, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CARTS OR
OTHER VEHICLES FOR THE REMOVAL OF SNOW FROM STREETS, ROADS, AND OTHER
PLACES, AND IN APPARATUS CONNECTED THEREWITH FOR MELTING THE SAID SNOW
AND DISPOSING OF THE WATER THUS PRODUCED, THE SAID CARTS BEING ABLE TO
BE APPLIED, IF REQUIRED, TO OTHER USEFUL PURPOSES," to be as follows:-
This Invention consists of the combination of a furnace and snow-
melting apparatus with a cart or other vehicle, which may or may not
be used as an ordinary water cart.
A wrought-iron tank is mounted on wheels, say four in number, and
has shafts (or a pole) fitted thereto together with a seat for the driver as
in ordinary water carts. At the top of the cart and constituting the
whole of its upper surface (except the seat for the driver) is a hopper or
other suitable receptacle for the snow as it is delivered from the shovels
or hods of the scavengers. The hopper is divided into two parts, an
upper and a lower chamber, by means of a sieve or perforated plate
which prevents the entrance of stones and other foreign bodies into the

page_text: lower chamber. It is preferred to allow the hinder end of the hopper
to project somewhat over the tank, so as to allow the furnace to be
placed under the projecting end and thereby to give its heat directly
thereto. The heat is applied to the lower chamber of the hopper by
means of serpentine flues from the furnace placed in the said lower
chamber and having interstices into which the melted snow can enter,
so as to utilise the heat to the fullest extent. The passage of the water
into the tank is accomplished by means of a large pipe with its mouth
projecting into the upper chamber of the hopper; it is preferred to cover
this pipe with strong wire gauze. When the vehicle is intended to be
capable of use for watering the roads, as well as (in the winter time
only) for collecting and melting the snow, the furnace and hopper may
be removable and the vehicle can be fitted with a branch pipe and
distributors, including the improvements described in the Specification
of a Patent granted to James Rawthorne and Edward Hudson Bayley,
No. 889, (A.D. 1866). The outlet from the tank for the water from
snow may be through the said branch pipe, or through a specially con-
structed sluice valve and hose. As the snow is fed into the hopper it
comes into contact with the sieve, which is itself in contact with the
upper surface of the flues, melts and fills up the lower chamber and
as much of the upper chamber as reaches to the level of the tank pipe.
The lower part of the snow is thus always in warm water and gradually
melts and supplys the tank.
Modifications of this plan may be employed. The hopper need not
extend over the whole surface of the top of the cart, but may be placed
merely on the hinder portion thereof.
The flue surface may be obtained by placing a rectangular flue box
under the hopper, the said box having suitable partitions to form the
proper path for the furnace heat; this plan renders the sieve unnecessary.
The cart may be covered with felt or with "Spence's non-conducting
composition. Salt (chloride of sodium) or other suitable agent may be
used to accelerate the melting of the snow, and this may either be
regained by chemical processes or not.
