An Improved Machine for Cleaning Roads and the like.
CORNELIUS JESSON, Lyric Villa, Hill Avenue Victoria Park, Bristol,
Musician do hereby declare the nature of this invention to be as follows:-
A wooden frame for carrying a main wheel which runs on the ground & receives
its motion from that source. This wheel drives chains by which are actuated a
rotary brush for gathering the dirt, & an endless band for carrying said dirt from
brush to cart or receptacle for containing such dirt. The frame may also carry a
tank with water which is taken through suitable pipes or conveyances to the front
of the machine for the purpose of damping the road before sweeping. There are
two wheels in the front of the frame for the guiding of said apparatus. The wheels
& brush are provided with suitable springs & apparatus for raising or proper
adjustment of same.
The whole of the machine can be attached to the back of a cart, which drawn

Musician 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 improvements in sweeping machines especially with
reference to those that are for sweeping streets, roads, thoroughfares and the like
places.
In order that my invention may be more clearly understood I annex hereto one
sheet of drawings which are to be taken and read as parts of these presents. Like
letters correspond to like parts in all the drawings.
Figure 1. is a plan of the machine looking at it from the top.
Figure 2. is a sectional elevation through the line A. B.
Figure 3. is a detailed plan of the clutch arrangement of machine.
The arrow in front of Figures 1 & 2 show the direction the machine is supposed
to be travelling and other arrows show the direction the chains are likewise moving
when machine is progressing in the direction of arrow in front of Figures 1. & 2. &
at same time working.
C is the framework of the machine which may be made of wood, iron, or other
suitable material and may be of any desired section or shape suitable for the
purpose and desired use of this machine.
D is a chain driven by a chain-wheel W attached to shaft D and driving a
chain-wheel W1 attached to top roller shaft H³.

D2 is a chain driven by a chain-wheel W attached to intermediate shaft K aud
driving a chain-wheel W³ attached to top conveyer shaft E¹.
D³ is a chain driven by a chain wheel 'W attached to intermediate shaft K and
driving a chain wheel W' attached to brush shaft Q.
For the sake of brevity it is to be understood that all shafts where required
have suitable journals and work in bearings in any of the usual and well known
and suitable forms or patterns.
The roller shaft H³ has attached to it a cylindrical or other suitably shaped
roller H the drawing shows a round roller and in the following discription it will
be assumed to be such. His a similiar roller placed near the ground. Over the
rollers H H is a sheet apron or wide band S to which motion is given by means
of chain D' and chain-wheel W' which actuates roller H.
H2 is a roller tending to support the travelling sheet S and to prevent it from
sagging the axle of such roller H' may be adjusted in a more or less vertical
direction so as to tighten the sheet S as may be required.
M¹ slot in which can be slid the bracket carrying the
journal of the shaft H³ revolves.
bearing in which the
E are chains carried over chain-wheels G G of which is the actuating or
moving chain-wheel and G₁ the idle or following chain-wheel. The chain-wheels G
are fixed to conveyer shaft E' and the chain wheels G¹ are fixed or free to revolve
on hottom conveyer shaft G*.
F are scrapers or conveyers moving in the same direction as the sheet S and also
in more or less close contact with sheet S.
G2 is a jockey roller to keep chains E from sagging downwards and is adjusted
in the same manner as roller H2 hereinbefore described. M is a slot in which can
be slid the bracket carrying the bearing in which the journal of the shafts E¹
revolve.
The actuating mechanism is shown in detail in Figure 3.
The power for actuating the mechanism is supplied by whatever means are used
for draught. Upon the machine being moved the wheels I 13 which are in contact
with the ground revolve On the side of the wheel 13 is fixed one jaw L of any of
the usual and well known forms of clutches. The ground wheels 1, 13 are free to
revolve but the portion of the shaft upon which they revolve is reduced in diameter
the middle part J, being longer and the ends D upon which wheels I 13 are free to
revolve being smaller in diameter. M² is a feather on the large part J of
shaft JD and fits in a corresponding feather-way on the part L' L' of clutch.
Lis the projecting portion of clutch part L L which fits into the recessed part
of clutch L. L2 is a chase in clutch part L' L' into which finger N fits. The
finger N is attached to sliding bar N' which is allowed lateral movement by means
of an elongated slot at N' and slides upon and is retained in position by means of
bolts N³.
At the end of the sliding rod at P a rack is cut, and into this rack fits a
pinion O, this pinion being fixed to a rod O¹ to which is attached a hand-
wheel O².
Fixed to the larger part of the shaft is a spur-wheel I' which gears into a
pinion 12 which is fixed to the intermediate shaft K having at or near its ends
chain-wheels W2 W. The chain-wheel W by means of chain D³ communicates
motion to chain wheel W which is fixed to brush shaft Q attached to brush
shaft is a circular sweeping brush Q
The axle of the brush shaft Q works in a bearing formed in the end of a hinge
lever the hinge or pivoted part of the lever being at V1 the bearing of the lever
into which the axle of the brush shaft Q is fitted being at V. The body or arm
of the lever being indicated by V.
TT T is a bell-crank lever of which T is the long arm and has formed on it a
handle. T is the fulcrum T the short arm which is connected to the hinge
lever V V1 V2 by the link and knuckle joints T³. U is a supporting wheel for one
end or corner of the frame of the machine C.

page_text: Having described the various parts of the machine its action when working will
now be described.
The machine being moved in the direction as indicated by the arrows, and the
clutch L, L L being thrown into gear by means of the finger N and the sliding
bar N which are actuated by the hand wheel O2 hand wheel rod O' and rack and
pinion PO, motion is then given to the spur wheel 1 and pinion 12 and the
respective shafts to which these toothed wheels are fixed.
The chain-wheel W' being now put in motion by means of chain D' and chain-
wheel W and connected moving parts puts in motion the chains E carrying the
conveyers or scrapers F.
Simultaneously the chain wheel W by means of the chain D³ operating on
chain-wheel W and thence by means of the connected moving parts the brush Qis
revolved and having been lowered into position by means of the bell-crank T T' T'
and the hinge lever V V V2 so as to brush against the ground, sweeps and throws
dirt upon the apron or travelling sheet S.
The sheet S is likewise simultaneously with the other parts is put into motion
by means of chain wheel W chain D₁ and chain wheel W' and from thence by
means of connected moving parts the roller H is revolved. As the dirt is brushed
on the travelling sheet the tendency for it is to move in the same direction as the
sheet and this direction of movement is assisted by means of scrapers F until the
dirt is raised on or about the topmost portion of the sheet S when it passes over
the highest point of the roller H and the dirt thence falls into any receptacle
provided for receiving it.
Instead of chains and chain wheels as herein before described worm & worm
wheels in which the worm may slide upon a feather or belts and cords or any other
well known mechanical equivalents may be used.
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. The use of moving band or apron in combination with elevators as hereinbefore
set forth and described for the purpose hereinbefore named.
2. The combination of a revolving brush in combination with a moving band
and elevator as hereinbefore set forth and described for the purpose hereinbefore
named.
3. The arrangement clutch and spur gear in combination with the driving
mechanism for actuating travelling band and revolving brush as hereinbefore set
forth and described & for the purpose hereinbefore named.
4. The combination of parts for raising & lowering the revolving brush as
herein before set forth and described & for the purpose hereinbefore named.
