Improvements in and relating to Carts for the Removal of Refuse.
I, CARL AUGUST ERNST DE LA SAUCE, Engineer, of S Usedom Strasse, Berlin
in the German Empire, 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 :-
The improved method of and apparatus for removing domestic refuse forming
the subject of this invention consists in emptying the receptacles or tubs filled with
ashes and other refuse into the dustcart while confining the dust raised thereby in
the cart and its attachments and in the construction and arrangement of the cart
and attachments suitably for this purpose and of apparatus for lifting and emptying
the tubs, the object being to save labour, carriage and time. By removing the
refuse in the manner aforesaid the carriage of the filled tubs to the refuse yard
and return carriage of empty tubs is obviated, which at present is necessary if the
inconvenience of dust in the streets is to be avoided. The return of the emptied
tub to its previous position can also be obviated in a simple manner by carrying
along in the cart an empty tub which is exchanged with the first filled tub, the
latter being emptied into the cart by means of the improved apparatus with
confinement of the dust while the eart proceeds to the next place of collection, where
the now emptied tub is agam exchanged with a filled tub and the Intter emptied
while the cart proceeds without pausing dust in the street, and so on.
In this way
a dust free removal of the refnse is greatly facilitated, as the car is no longer
uselessly loaded with empty or filled tabs or receptacles, and time and labour are
saved.
On the drawings appended hereunto a cart for the dust free removal of domestic
refu-e according to my invention is represented as an example how my invention
may be carried into effect,
Fig. 1 showing a side view and Fig. 2 a back view of the improved dust cart.
Fig. 3 a sectional back view, along line of Fig. 1.
Fig. 1 shows a modified form or arrangement of dust cart.
Referring to the drawings, on the cart frame a is carried an iron preferably
cylindrical receptacle for the domestic refuse. At the top of the back end of the
receptacle an opening c is arranged, which for the purpose of allowing the filled tubs
to be emptied through it into the receptacle & without dispersion of dust is covered
over by an iron houd d, which by enclosing the tub while it is emptied prevents dust
to be blown about.
The tubs to be emptied are placed upon a lift or cage underneath the hood,
the platform of the cage resting upon brackets. The cage e is suspended OH two
endless chains g' attached to the cage at the sides at the points g, which chains pass
over the guide pulleys h, h, h, driving chain pulleys or wheels i and the studs k
on the sides of the cage. The cage is guided in the grooves 7, into which the
stud-fixed on the cage engage. The raising of the cage with the tub can
be effected by means of two cranks, o, put upon the shaft p. Upon the latter
is fixed a spur wheel y which gears with the wheel q on shaft pon which the
driving chain pulley or wheel is fixed. The raising of the cage however
can also be effected by means of a chain wheel on shaft p which is connected
by means of a driving chain to the chain wheel on one of the back wheels of
the cart.

page_text: As soon as the cart is put into motion, or the cranks are turned in the suitable
direction, the cage is raised into the hood d up to the closed end of the
guide grooves 1. The cage with the tub then turns on the studs m into the
position shewn in dotted lines on Fig. 1, when the opening or top of the tub
will coincide with the inlet opening of the receiver and the tub empties
itself into the receiver. As the cage reaches this position, it shifts the lever a
fuletured on a stud on the inside of the hood into a position indicated by a on
Fig. 1. The bottom end of this lever is connected by a chain or cond passing
over a guide pulley to a bell crank lever engaging with a fork on its vertical
limb into a groove on the friction coupling y, so that by the movement of lever a
the friction clutch is shifted and disengaged from the spur wheel y carrying the
she cone of the clutch. The clutch slides on shaft plon
key, while the
spur wheel is loose upon the shaft, so that the disengagement of the friction
clutch stops further rotation of the shaft p'and the chain pulleys i mounted thereon.
When the enge is to be lowered again, either the cranks are turned back-
wards or the chains g hanging below the hood are drawn down, the handle
of the bell erank being raised at the same time to keep the friction clutch
disengaged.
In order that the refuse poured into the receiver may not remain heaped up
at one end, a spiral or worm conveyor is arranged inside of the same, which
when the cart travels, is rotated through the bevil wheels A and upright shaft A';
and thus moves the refuse towards the front. For emptying the receiver
suspended in a crane on the eye 13, lifted off the cart frame and inclined toward
the front, after which the sling dar Dis opened by turning the handle Cand
the contents of the receiver slide out.
it is
It is evident that the construction of the apparatus may be modified without
departing from the essential feature of this invention, which consists in effecting
the dust free removal of refuse by emptying the tubs underneath a hood into a
closed receiver by means of mechanical lifting apparatus operated by hand or from
the cart wheel while the cart proceeds, whereby the advantages herein fore
indicated are obtained. For instance Fig 14 shows a similar cart in which the
conveyor Fig. 1 is dispensed with, the bottom of the receiver being inclined so
that as the cart is driven along, the reluse automatically moves forward. The
apparatus for lifting and tilting the tubs may also be modified from those described
and replaced by equivalent apparatus effecting the same result.
K
By the use of the hereinhetore described method of and apparatus for collecti
refuse, the molestation of the neighbourhood by dust is prevented, the carriage of
empty tubs rendered unnecessary and Inbour and time saved, especially if the
emptying is effected in the hereinbefore described manner while the cart proceeds
froin one place of collection to another.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I hereby declare that
what claim is
1. The method of removing refuse by emptying each filled tub into a covered
receptacle on the dust cart by mechanical apparatus and with confinement of the
dust, such emptying being either effected at once and the emptied tub returne to
its receiving location, ar during the progress of the cart from one collecting place
to another, one emptied tub being in that case exchanged with the next filled one,
substantially as and for the purposes hereinbefore described.
2. For carrying out the method claimed in the preceding claim the combination
with a dust enrt having a covered receiver provided with a charging opening, of a
hood or its equivalent and of mechanical lifting apparatus worked by hand or from a
wheel of the cart so arranged that a tub placed into the cage of said apparatus is
lifted to the charging opening and tilted so that its opening covers the charging
opening underneath the hood or its equivalent, substantially as hereinbefore
described and illustrated by the drawings.

lifting and emptying apparatus substantially as hereinbefore described and
illustrated.
