Improvement in Drainage and Watering Carts.
We, JOHANN STEINFELD, Gentleman, and THEODOR BECKER, Engineer,
both of Mülheim on the Rhine, in the Province of Rhineland and Kingdom of
Prussia, 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 :-
Up to the present sinks were generally emptied either, as is customary in the
country, by pumping out the night-soil by means of a hand-pump, or as is done in
emptying sinks in the town, by means of a pump, carried on a special carriage and
worked by hand or steam, which pumped the fluid into large barrels..
The invention now to be described and explained by drawings, very considerably
simplifies the emptying of such sinks, by making it possible to dispense with a
special pump working during the operation of filling.
The arrangement of the new transport-cart consists, as will be seen from
Figs. 1 and 2, in the adaptation of two air-pumps, which are attached below the
barrel A to the frame of the cart and each connected with the former by a pipe-
shoulder d. containing a valve.
These pumps consist in their simplest form, as will be seen from Fig. 4, of a
cylinder a open on one side, in which a valve-piston b is moved to and fro by means
of the piston-rod c.
The piston-rods of both pumps are attached to the shaft e provided with the
cranks and bearing the loose toothed wheels g g
These wheels catch in the
toothed wheels ii which are fixed to the axle h of the cart.
Between the loose toothed-wheels g and the cranks f the shafte is four-sided and
carries a coupling-disk n (Fig. 3) which can be connected with the wheels g by
means of the pins o.
=
The barrel, as may be seen from Fig. 1, is divided by the partition w into two
divisions A and B of which the former is the larger and receives the drainage
matter. This.division A is connected with the smaller one B by means of a tube m
provided with a cut-off valve (screw-down valve) and vacuum gauge. The tube m
may also, as is shewn by the dotted lines in Fig. 1, be arranged above the barrel A.
The apparatus thus described is intended, while the carriage is driving empty to
the sink, to create as great a vacuum as possible in the space A, so that the
contents of the sink can be forced into the barrel A by the pressure of the
atmosphere, by means of a hose which is screwed on to the cock p. of the barrel.
For this purpose the coupling-disks nn are made to gear with the wheels 99,
and the rotation of the carriage-wheels, i.e. the toothed-wheels ii connected with
their axles is transmitted by the wheels g g to the cranks f, by which means the
pumps are set in motion.
After the barrel has been filled, the coupling-disks are put out of gear, so that
the pumps do not work when the cart is full.
As, when the barrel continues to fill, the rarefied air coutained in it, begins to get
somewhat denser, it might happen that the barrel did not become perfectly filled.
On this account the reservoir B, which, in consequence of the valve k being shut
off, also contains rarefied air, is of great use, because the condensed air in A flows
over into B, after the valve h has been opened, so that the fluid cau now fill the
whole space A.
The space B, it is true, might also be dispensed with, and the tube m empty
itself directly into the valve of the pumps a.
The apparatus is also suitable for street-watering purposes in such towns where
there are no water-works, but where there is flowing or stagnant water in the

page_text: neighbourhood.
It is only necessary then to attach a rose below the cock p, as is
usual in watering carts.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :
Cart for emptying sinks and street-watering, distinguished by the arrangement of
one or more air-pumps worked by the wheels of the cart in such a manner, that on
the cart being driven in an empty state, the barrel is deprived of air by means of
the pumps, while on the barrel being filled, the pumps cease to act in consequence
of the putting out of gear of suitable coupling parts.
