PROVEMENTS IN CLEANING STREETS, AND IN APPARATUS CONNECTED THEREWITH.",
My Invention relates to an improved mode of cleaning streets, and consists in
forming cavities or recesses at intervals in the gutters for the reception of portable
boxes or receptacles into which the dirt and refuse may be swept, and in the
employment of tipping mud carts fitted with hoisting gear for elevating such boxes
or receptacles as required in order to empty their contents into the cart, and for
lowering the boxes or receptacles again into their cavities or recesses, the dirt and
refuse being subsequently conveyed away by the cart and discharged by tipping the
body of the same at the place where the dirt and refuse is required to be deposited
or utilized.
The cavities or recesses and the boxes or receptacles are so arranged in rotation
to each other that the boxes or receptacles when in their place are situate below
the surface of the gutter, and the cavities or recesses are closed by moveable covers
applied to them direct or by hinged lids applied to the boxes or receptacles, or by
both appliances employed in combination if desired.
The tipping carts may be of any suitable construction provided that they be fitted
with hoisting gear for raising and lowering the boxes or receptacles as before
mentioned, but I prefer to employ the arrangement herein-after described.
According to one modification the body of the cart, which is composed by
preference of boiler plate, is constructed of a segmento-cylindrical trough shape, the
centre of gravity being so arranged that the body preponderates towards the rear,
whilst a suitable bolt or catch is employed in order to retain the body normally in
its horizontal position. The body is mounted in a skeleton frame which carries the
axletrees for the wheels, and also on one side supports the windlass of the hoisting
gear, whilst the other side carries a roller or rollers over which pass the hoisting
chains to be attached to the box or receptacle. The side last mentioned of the frame
is made in two parts hinged together in such a manner that when the box or
receptacle is raised to a sufficient height, and is brought into contact with a suitable
holding clip or catch, the upper part carrying the rollers, and the box or receptacle
falls inwards, whereby the box or receptacle is tilted or partially inverted, and its
contents are discharged into the body of the cart; after the tilting of the box or
.

moveable portion of the frame is re-elevated under the action of a powerful spring
when the box or receptacle may be re-lowered into its place.
According to another modification I construct the upper part of the frame
carrying the roller, over which the hoisting chain passes somewhat in the form of
the jib of an ordinary crane, and fit it to the main body of the frame in such a
manner that when the box or receptacle is raised to the requisite height the
moveable portion or jib of the frame may be moved or swung round, so as to bring
the box or receptacle immediately over the body of the cart, when the box or
receptacle may be tilted or partially inverted under the action of any usual or
suitable tipping appliances, the box or receptacle being subsequently re-lowered into
its place in its cavity or recess for the reception of a further charge of mud and
refuse to be swept into it as before mentioned. In this case the windlass is more
conveniently carried on a stand projecting from the frame on the same side as
the moveable portion or jib, but it may be otherwise arranged according to cir-
cumstances.
The lower part of the hoisting chain or chains is fitted with appliances, such
for example as those employed in pile driving machines or boat lowering apparatus
for automatically connecting and disconnecting the box or receptacle at the required
periods.
