An Improved Dust Cart.
I, THOMAS HERBERT GASKIN, of 22, Pigott Street, Limehouse, London, E.,
Shipwright, do hereby declare the nature of this invention to be as follows:-
My invention relates to carts for the collection of household and other refuse
and has for its object to provide means whereby the separation of the refuse into
dust, cinders, and miscellaneous matters will be effected automatically by the
travelling motion of the cart, through the medium of screens receiving rapid
reciprocating motion from the travelling wheels.
For this purpose the internal capacity of the body is suitably divided so as
to keep the products of the different screenings separate, the general arrange-
ment of the compartments and screens being as follows:-The body of the cart
is entirely closed with the exception of a feed hopper at the upper part below
which is arranged an inclined screen or grid to which rapid reciprocating motion
is imparted, the inclination of the screen being downwards towards a compart-
ment at the back in which the gross refuse that does not pass through the screen
is received. The matters which pass through the screen are received upon a
second finer screen situated beneath and inclined in the opposite direction to the
first which also receives reciprocating motion to and fro in the direction of its
inclination, the cinders which do not pass through the screen being delivered
to one compartment whilst the dust which does pass through is delivered to
another, suitable means of access to these compartments being provided for the
separate emptying of their contents..
is
The screens are driven preferably from both rear wheels of the cart through
the medium of ratchet, clutch, or balance gear whereby both wheels are caused
to participate in the driving action in normal running whilst the independent
revolution of the wheels when running in curves, as in turning a corner,
permitted. The motion is transmitted through bevel and multiplying gear to
a crank or its equivalent connected to a rock shaft having oppositely extending
arms coupled to the sieves and imparting motion thereto preferably in opposite
directions so as to permit of rapid reciprocation without undue vibration of the
body. Means are provided for throwing the screen-operating mechanism out
of action when not required.

page_text: I, THOMAS HERBERT GASKIN, of 22, Pigott Street, Limehouse, London, E.,
Shipwright, 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:-
My invention relates to carts for the collection of household and other refuse
and has for its object to provide means whereby the separation of the refuse into
dust, cinders, and miscellaneous matters will be effected automatically by the
travelling motion of the cart through the medium of screens receiving rapid
reciprocating motion from the travelling wheels.
The invention will be described with reference to the accompanying drawings
forming part of this specification wherein I have represented in Figures 1 and 2
opposite side elevations of the cart, portions of the side being broken away to
shew the internal construction.
For the purpose of this invention the internal capacity of the body of the
cart is suitably divided into compartments A, B, C, by transverse partitions so
as to keep the products of the different screenings separate, the general arrange-
ment of the compartments and screens being as follows:-The body of the cart
is entirely closed with the exception of a feed hopper D which surmounts the
body of the cart. Below the hopper D is arranged an inclined screen or grid E
to which rapid reciprocating motion is imparted, the inclination of the screen
being downwards towards the compartment C at the back of the cart in which
the gross refuse that does not pass through the screen E is received. The
matters which pass through the screen E are received by a hopper F and delivered
to a second finer screen G situated beneath the hopper F and inclined in the
opposite direction to the first screen E the second screen G also receiving recipro-
cating motion to and fro in the direction of its inclination. The cinders which do
not pass through the screen G are delivered to the compartment A whilst the
dust which does pass through is delivered to compartment B. Suitable means
of access to these compartments is provided for the emptying of their contents.
For this purpose the compartment A is provided with a door A¹ at the side of
the cart body, the door being hinged at bottom and provided with internal side
flanges A2 so as when dropped down, as shewn in dotted lines, to form an inclined
shoot discharging clear of the front wheel. The partition which separates
compartments A and B is provided with an aperture closed by a sliding door 13¹
through which the contents of compartment B can be shovelled into A and out
at A' after A has been emptied; the compartment C being provided with a door C'
at the back of the cart body and the partition separating B and C being also
provided with an aperture closed by a hinged flap B² capable of being raised by
a chain to allow the contents of compartment B to be discharged into compart-
ment C if preferred. The compartment A is also provided with a hinged flap or
door A³ on top and a similar door or doors being provided at H.
The screens E and G are driven preferably from both rear wheels I I¹ of
the cart through the medium of ratchet, clutch, or balance gear whereby both
wheels are caused to participate in the driving action in normal running whilst
the independent revolution of the wheels when running in curves, as in turning
a corner, is permitted. In the example shewn the axle J is mounted to turn in
bearings beneath the body of the cart and has fast on it ratchet wheels ; one at
each end. With each ratchet wheel engages a pawl carried by the hub of the
aljacent wheel so that when the cart is moved forwards the axle will be driven

page_text: by both wheels or by one of them only according as the cart is moving in a
straight line or in a curve. The motion is transmitted from the wheel I through
a bevel gear wheel K and a pinion K¹ on a shaft L geared by bevel wheels M M¹
with a cross shaft N provided with a spur wheel O which gears with a pinion P
on a countershaft P₁ provided with a crank or eccentric Q coupled by a link Q¹
to a crank arm on a rock shaft R having oppositely extending arms ST coupled
by links S T to the sieves E and G and imparting motion thereto in opposite
directions so as to permit of rapid reciprocation without undue vibration of
the body. Means are provided for throwing the screen-operating mechanism
out of action when not required, by fitting the pinion K' to slide on the shaft L
with a feather connection and providing a clutch lever U for throwing the
pinion in and out of gear with the wheel K.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The herein described cart for the collection and screening of refuse, the cart
having the body divided into compartments, screens delivering from one to the
other and to the compartments as described, the screens being mounted to
vibrate in the upper part of the body and combined with mechanism substantially
such as described for vibrating them, driven from the wheels of the vehicle in
travelling as described.
