COMPLETE SPECIFICATION.
An Improved Cart for Conveyance of Refuse and other Matter.
I, HERMANN SCHELLER, Merchant, of Fennstrasse 53-54, Berlin, in the Empire
of Germany, 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 :-
This invention relates to carts or carriages for conveyance of dust, rubbish or
other refuse or matter of a dusty nature, and especially to such carriages which for
this purpose are provided with an arrangement of several compartments formed by
a guard-plate and a curtain as under Letters Patent No. 9249 of 1895. In such
carriages the inconvenience is found that the operatives may omit to close the
upper ventilation valve of those compartments which have already been filled, or
are just filled, so that the dust may pass through these opeuings which renders
nugatory the object and effect desired for the carriage.
The purpose of this invention is to prevent this inconvenience anl it is obtained
by replacing the ventilation valves swinging round hinge-joints by slides moving
over one another which are moved by the curtain and secure the closing of the
ventilation openings in the compartment-just used.
The annexed drawing shows in Fig. 1 a longitudinal section through the
carriage and in Fig. 2 a cross-section on line -.
The front compartment a of the carriage has no ventilation openings, as the
operatives have not to remain therein, and it is closed on the top by the carriage
ceiling a' the other compartments possess an opening passing through and
common to both. This opening is closed by sliding covers which are connected
with the curtain c in such a manner that the rod e, which carries the curtain and
slides upon the round iron rods d, is connected solidly with the under sliding
cover f. When the front compartment is filled and the curtain is moved, the
bow e carries with it the sliding cover f and closes the ventilation opening of the
next compartment.
When then the second compartment is filled and the curtain is moved further ou,
the raised end f' projecting upwards moves the downwardly projecting border g' of
the slide cover g which now covers the middle compartment, while the cover f passes
over the third compartment.
It will be seen from the arrangement the operatives are obliged to close the
ventilation openings when the carriage is loaded as in order to be protected
themselves against the dust they will close the curtain in their own interest.
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 :-
A cart or carriage of the nature set forth for conveyance of refuse or other
matter, having slides which close the upper ventilation openings and which
are moved by the curtain in such a manner that the compartment in which the
matter has just been placed is and remains closed on all sides.
