Improvements in Dust Carts.
I, LEOPOLD BÜRGER, of No. 8 Teinfaltstrasse, in the City of Vienna I, in the
Empire of Austria, Banking Clerk, do hereby declare the nature of my said
invention to be as follows:-
-
The many attempts which have been made to provide a means for removing
street-sweepings, refuse and the like, so as to meet all hygienic requirements, show
that no effective and satisfactory result has been arrived at.
In order to fully meet all requirements, this improved cart is provided on the
top with a neck like extension or extensions having a closable lid, on which
receptacles or collectors in which the dust or refuse is collected, are placed either
by means of suitable mechanical arrangements or by hand; on operating a lever
the lid of said extension and the bottom of the receptacle are opened simultaneously,
when the contents of the latter falls by virtue of its own weight into the cart,
without it being possible for any of the dust etc. to escape again.
The body of the improved cart is in the form of a chamber, preferably of sheet.
iron, and mounted on a suitable frame work. On the top of the chamber is a neck-
like extension on which the collectors containing the dust or other refuse are
placed either by hand or by means of a suitable mechanical device suitably
arranged on the cart. Each collector is of the form of a truncated cone and
provided with an easily closable lid and a bottom in one or two parts turning on
hinges. The said extension on which the collector is placed is likewise provided
with a lid preferably in two parts which open simultaneously with the bottom of
the collector by operating a handle connected by a series of rods and a chain or
cord to two levers pivoted on the said extension. Immediately the said handle is
pulled the lid of the extension is first released when said levers strike one end of
two short double-armed levers likewise mounted on the extension and whose other
ends are thereby forced between the sides of the collector and the spring lugs
supporting the two halves of the bottom of the collector. On said supports being
withdrawn, therefore, the bottom of the receptacle falls open and the dust empties
itself into the cart. On releasing the handle, weights suitably arranged on the
free ends of said levers bring back the lid of the extension into its normal position,
which lid at the same time forces the bottom of the collector into its closed
position; the spring lugs then fall underneath of and thus support the latter.
The simultaneous opening and closing of the bottom of the collector and the lid of
the extended neck may also be effected by fixing to each half of the lid a rotable
shaft, connected by toothed segments and suitable attachments so that the same
movements are imparted to each half of the lid on the handle being operated.
The bottom of the collector is opened and closed at the same time as said lid by
means of a secondary shaft and segments suitably brought into connection with
the arms of the lever operating the lid. The bottom of the collector is prevented
from flying open too early by angle iron supports attached to and operated by one
of said levers. The lid and bottom respectively take up their normal position
when the operating handle is pushed into its original position.
The bottom of the cart is preferably made of two hinged parts either inclining
towards the centre like a hopper bottom, or highest in the centre and inclining
towards the sides; the contents may thus be rapidly let out of the bottom of the
cart either at the centre or at both sides.

page_text: The cart may also be provided with a distributor consisting of one or more rails
operated from without the cart by a handle. By this means the dust etc. is pushed
evenly all over the cart by a simple turn of said handle, and the capacity of the
cart thus fully utilized.
In order to kill any infectious germs i.e. to disinfect the cart, perforated
pipes are arranged in the bottom of same, through which steam may be passed.
The body of the cart instead of being firmly attached to the frame may also be
mounted on a turn-table, in order to facilitate the operation of same, after turning
the turn-table; or, in case the cart is to be transferred to a railway carriage or
truck, the turn-table may be substituted by suitably arranged rollers.

Improvements in Dust Carts.
I, LEOPOLD BÜRGER of No. 8 Teinfaltstrasse, Vienna I in the Empire of
Austria, Banking Clerk, 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 an improved cart for removing street-sweepings, ash-
pit refuse and the like, its arrangement and construction being such that the
receptacles or collectors in which the dust, refuse or the like is collected, form an
integral part of the cart proper.
These receptacles or collectors are placed on neck-like extensions of the cart,
either by hand or mechanically, and are provided with folding bottoms, which, on
being released, are forced open, as also the like folding lids of the extensions, by
virtue of the weight of refuse in the collectors. By this arrangement, therefore,
the collectors are emptied into the cart without any, of the dust or finer particles of
the refuse being able to escape.
Referring to the accompanying drawings,
Fig. 1 is a side view of the dust-cart and
Fig. 2 an end view of same,
Figs. 3, 4 & 5 show in sectional plan and side views respectively the refuse-
collectors and the extensions for receiving same.
Figs. 6 & 7 show a modified means for opening and closing the collectors in
sectional side view and plan;
Fig. 8 is a detail of the modification shown in Figs. 6 & 7.
As shown in Figs. 1 and 2, the cart comprises the body a, either stationarily
fixed or releasably attached to frame and provided with one or more neck-like
extensions c for receiving the receptacles d in which the refuse is collected, the
latter being placed on the extensions c, either by hand or by any convenient
mechanical device (not shown in the drawing) arranged on the cart.
Each extension c is provided with a lid c¹ (in either one or two parts) turning
with spindles c 2 and which, on the collector d being emptied, is opened and closed
at one operation, simultaneously with the similarly-constructed bottom d' of such
collector d.
In the arrangement shown in Figs. 3, 4 & 5, the two folding parts of the
bottom d¹ of the collector dare held in the closed i.e. normal position by spring
lugs or catches d 2. On the collector d being put onto the extension c the proper
position being secured by suitable guide marks or lugs, and a handle e (Fig. 1)
turned in the direction of the arrow (this movement being transmitted, for instance,
by a cord or chain g to the levers h mounted on the shafts c 2) the two halves of
the lid will turn on c2 and open. On continuing to turn the handle e the ends of

turning on pivot i, such arms being thus turned in the direction of the arrow and
the cain-like arms 12 12 forced between the walls of the collector d and catches d2
(Fig. 2); the latter are thus forced outwards, when the two halves of the bottom d'
lose their support and the weight of the refuse in the collector forces same open
and allows the refuse to fall into the cart. On releasing the handle e, the lid c¹
automatically returns to its normal position by counterbalancing weights /', on the
levers h, or by suitably arranged springs. Or the handle e may be forced back by
hand, in which case the bottom d' is turned back until it slides over, and is supported
by, the spring lugs d2 again; distance bolts d3 may also be provided for
regulating the position of bottom.d'.
Figs. 6, 7 and 8 show a modified means for opening or closing the bottom d'.and
lid respectively in one operation
mechanism. Each half of the lid
spindles K are connected by rods K¹,
a movement of each half of the lid
slot K 4 connects the rods K', K 2 to the handle m.
In order that the halves d' may be operated by the same handle m, a further
spindle n is provided with two segments n¹ each having a slanting groove n2
(Fig. 8) in which engage the arms o³, or rollers o 3, of a double armed lever o¹ 02
pivoted at o. The arms of have pins 04 04, between which the bell crank
levers p pivoted to the collector d, slide when the latter is regularly placed onto
the extension c. In the position shown in the drawing, the bell crank levers, or
arms p, engage the underside of the bottom d¹ and thus prevent same from opening
and the contents of the collector being prematurely emptied. Levers n3 and
rods n 4 having slots n connect the spindle n and segments n¹ with the handle m.
On turning the lever m in the direction of the arrow, the halves of the lid c¹
are opened as indicated by the arrows, while the halves of bottom dare not acted
upon and opened by the weight of the refuse until the lever m has almost reached
the extreme end of its movement, viz., until a pin on the lever reaches the end of
the slot n 5, whereupon the segments n¹, n¹ are turned for a certain distance in the
direction of the arrow by means of the connections n 4, n 3.
by means of the following hand-operated

At the same time the levers o', 02 are moved in the direction shown by the
arrows, by the grooves n 2 in segments n', the bell crank levers p being thus
forced from the collector d and the contents of the latter allowed to fall through the
now unsupported bottom d' into the cart.
On turning the handle m in the opposite direction, the halves of the lid c¹,
together with those of bottom d are raised and the segments n¹ returned, as
soon as the handle comes in contact with the opposite end of the slot n 5; the bell
crank levers p thus take up their normal position for supporting the bottom d¹
again. During the latter movement the connecting rods K3 and lid c¹ are not
operated, because their movements are regulated by the slot or cam K 4 of the
rod K 3.
It will be evident that both the spring catches d2 and the bell crank levers p
may be operated by hand, in which case the lid c¹ of extension c would be operated
by a suitable lever. The extensions and the collectors d would also be
simultaneously closed in the manner afore-described, so that it would only be
necessary to provide a handle for closing the collectors by means, for instance, of
suitably arranged bell crank levers.
It is of great importance that the cart which is perfectly closed in order to
prevent the escape of dust, is provided with means for rendering its contents not
injurious. For destroying any infectious gerins in the refuse, it is therefore,
preferable to arrange a series of steam pipes in the lower part of the cart and
to provide same with slits or perforations or to make them of elastic material
longitudinally divided or slotted (Figs. 1 and 2). On blowing steam through these
pipes with sufficient pressure all germs and organic matter are destroyed, and this
without the refuse deteriorating in value for manuring purposes.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A dust cart, having one or more extensions (c) for receiving the refuse
collectors (d) and provided with folding bottoms (c'), such collectors (d) having
like folding bottoms (d'), which latter are opened by the handle (e) being turned
in such manner that the nose-like ends of spring-lugs (d2). are drawn from
underneath each half of bottoms (d') substantially as described and shown in the
drawing.
2. In a dust-cart as set forth in Claim 1 spring-lugs (d2) supporting bottom (d')
of collector (d) and being withdrawn by cam-like arms (2) on the handle (e)
being turned, substantially as described and shown in Figs. 1–5.
3. In combination with a dust-cart as set forth in Claim 1, bell crank levers or
cams (p) supporting bottom (d) of collector (d) and released by segments (n¹)
provided with cam grooves (n 2) for engaging one end of levers (o', o 2), their
other ends operating the cams (p), substantially as described and shown.
4. In combination with a dust-cart slotted pipes (w) of springing material arranged
inside the latter and through which steam under pressure is admitted for disinfecting
the refuse in the cart, substantially as described and shown.
