Complete Specification Left, 16th July. 1889-Accepted, 7th Sept., 1889
PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing Roadways and Clearing
the Snow therefrom.
I, AUGUSTIN HENTSCHEL of No. 32 Nenenburger Strasse Berlin, Prussia Manu-
facturer do hereby declare the nature of this invention to be as follows:-
My improvements relate to a construction of apparatus for melting the snow on
roadways and for washing the latter, for which I have received Letters Patent
No. 13765 dated 11th October 1887.
I will proceed to describe the said improvements with reference to the accompanying
drawings, in which Fig. 1 shews a side view of the improved machine, and Fig. 2
shews an underside plan of the same.
Experiments with the machine, described in my Specification No. 13,765 have
shown that it is not necessary for melting the snow that the water in the tank a
should be heated, and consequently the furnace in the tank described in the specifica-
tion is dispensed with.
The water-roller in the previous arrangement is also dispensed with, and in place
thereof I employ a perforated pipe which is suspended by a chain c from the framing
of the machine and is supplied with water from the tank a by means of a pipe d. At
the inlet end of this pipe is a valve e that can be opened or closed by means of a
lever.
The cleansing roller is arranged with its axis inclined, instead of being at right
angles to the direction of motion, as described in my former specification. The
caoutchouc strips upon the cleansing roller are arranged in helical lines, which are
however not continuous, but are formed of short strips of caoutchouc with small
intervening spaces as shewn at Fig. 2.
The cleansing roller receives its motion from the axle i through the toothed
gearing kkkk. The axle i carries the road wheels 1. A third road wheel mis
provided at the rear of the machine.
As shewn on the drawings, the roller is carried in a framing g that is pivotably
mounted upon the axle i and which also carries the gearing k; by this means the
cleansing roller can be adjusted to different heights, according to the varying level of
the road surface to be cleansed.
The machine is put out of action by raising the roller by means of the lever f,
which is fixed on a shaft carrying the double ended lever p one end of which is con-
nected by a rod to the frame of the roller while the other end is connected to the
valve e.
As shown at Fig. 2, the movement of the lever p, by the lever simulta-
neously effects the raising of the roller h, and the closing of the valve e, while on
lowering the roller h the valve e is at the same time opened.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Washing Roadways and Clearing
the Snow therefrom.
I, AUGUSTIN HENTSCHEL of No. 32 Ninenburger Strasse, Berlin, Prussia Manu-
facturer, 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:
My Improvements relate to a construction of apparatus for melting the snow on

page_text: roadways and for washing the latter, for which I have received Letters Patent
No. 15765 dated 11th October 1887.
I will proceed to describe the said improvements with reference to the drawings
accompanying my Provisional Specification in which Fig. 1 shews a side view of the
improved machine, and Fig. 2 shews an underside plan of the same.
Experiments with the machine described in my Specification No. 13,765 have
shewn that it is not necessary for melting the snow that the water in the tank a should
be heated, and consequently the furnace in the tank described in the specification is
dispensed with.
The water roller in the previous arrangement is also dispensed with and in place
thereof I employ a perforated pipe which is suspended by a chain e from the framing
of the machine and is supplied with water from the tank a by means of a pipe d. At
the inlet end of this pipe is a valvo e that can be opened or closed by means of a
lever f.
The cleansing roller is arranged with its axis inclined instead of being at right
angles to the direction of motion, as described in my former specification. The
caoutchouc strips upon the cleansing roller are arranged in helical lines which are
however not continuous but are formed of short strips of caoutchouc with small inter-
vening spaces as shown at Fig. 2.
The cleansing roller receives its motion from the axio i through the toothed
gearing kkkk. The axle carries the road wheels 11. A third road wheel m is
provided at the rear of the machine.
As shewn on the drawings the roller is carried in a framing g that is pivotably
mounted upon the axle and which also carries the gearing ; by this means the
cleansing roller can be adjusted to different heights according to the varying level of
the road surface to be cleansed.
The machine is put out of action by raising the roller by means of the lever f
which is fixed on a shaft carrying the double ended lever one end of which is con-
nected by a rod to the frame of the roller while the other end is connected to the
valvo e. As shown at Fig. 2, the movement of the lever p by the lever ƒ simul-
taneously effects the raising of the roller h, and the closing of the valve e while on
powering the roller h the valve e is at the same time opened.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. Apparatus for washing roadways and clearing the snow from the same consisting
of a water tank a mounted on wheels, in combination with a discharge pipe regulated
by a valve e, and with a cleansing roller carrying caoutchouc strips arranged in
helical lines, and driven from the axle of the machine substantially as herein
described.
2. In apparatus such as is referred to in the preceding claim, the combination of
the raising device for the cleansing roller with the shut off valve for the discharge
pipe substantially as herein described.
3. In apparatus for cleansing roadways, the use of a cleansing roller having
helically arranged strips of caoutchouc on its surface, such strips being either con-
tinuous or divided substantially as herein described.
