I, LUDWIG EPSTEIN, of Rosebank, East Twickenham, in the County of Middle-
sex, Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to means of propelling vans employed for collecting dust
and mud, and of operating mechanism for charging the vans.
For this purpose I provide on the van a secondary voltaic battery and an
electric motor with gearing so arranged that I can connect the motor to the
road wheels of the van thus effecting its propulsion, or can connect it to suitable
appliances such as a crane for lifting dust pails or baskets or a pump or other
appliance for removing mud, for the charging of the van.

I, LUDWIG EPSTEIN, of Rosebank, East Twickenham, in the County of Middle-
sex, Electrical Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and aseer-
tained in and by the following statement:-
My invention relates to means of propelling vans employed for collecting dust
and mud, and of operating mechanism for charging the vans.
For this purpose I provide on the van a secondary voltaic battery and an
electric motor with gearing so arranged that I can connect the motor to the
road wheels of the van thus effecting its propulsion, or can connect it to suitable
appliances such as a crane for lifting dust pails or baskets or a pump or other
appliance for removing mud, for the charging of the van.
The accompanying drawings represent one arrangement of a dust and mud
collecting van according to my invention, Fig. 1 being a side elevation, Fig. 2
an end view and Fig. 3 a plan.
a is an electric motor supplied with current from storage batteries b. The
shaft c of the motor a drives by two belts and pullies a countershaft d at either
of two speeds, both reduced, according as the one or the other belt is tightened
by tightening pulleys worked by levers e, f. A pinion on the shaft a gears
with teeth on the periphery of the casing g of differential gear from which are

page_text: driven two shafts h h from which by belts or chains the two road wheels i are
driven.
On the platform above these wheels is a tank to receive the dust and mud
collected by the appliance which I shall now describe,
A trunk containing an elevator is mounted on an axis on which when not
in use it can be canted to the position indicated by the dotted lines. On the
side of the trunk kis mounted a pulley in driven by a belt from a pulley on the
shaft d and attached to the pulley m is another pulley driving by a belt a pulley n
on the axis of the upper sprocket wheel of the elevator.
To the axis o of the lower sprocket wheel of the elevator is geared the axis of
a revolving brush 2 which sweeps the mud and dust into the bottom of the
trunk to be carried up by the elevator and discharged through a spout g into
the tank j.
The front wheels r r. are pivotted on the ends of an axle, these pivots having
lever arms s which can be connected to any suitable steering handle arranged
to turn both wheels simultaneously on their pivots.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A dust and mud collecting van having its road wheels and its dust and
mud collecting apparatus both worked separately or simultaneously by an electric
motor.
2. A dust and mud collecting van, arranged and operating substantially as
described with reference to the drawings.
