IMPROVEMENTS IN MACHINES FOR SWEEPING STREETS AND ROADS
Year: 1884

page_text: I JOHN BARROW of 8 Oldham Road, Miles Platting, in the County of Lancaster,
Mechanic do hereby declare the nature of said Invention for, IMPROVEMENTS IN
MACHINES FOR SWEEPING STREETS AND ROADS, to be as follows:-
My invention relates to improvements in machines used for sweeping streets and
roads and the object of my Improvements is to construct a machine that will brush
the dust, dirt, mud, snow or refuse into heaps instead of leaving it in rows which
are at present swept into heaps by men.
In performing my Invention I employ a frame preferably of metal which is free
to oscillate on the axle of the machine or other centre and balanced by weights (or
in other convenient manner) secured to the frame at the front of the machine: in a
bracket or by bangers secured to this frame at the back of the machine I fit a
revolving brush or brushes at an angle of about 45° (forty five degrees) or more or
less and in another bracket or by hangers a second revolving brush or brushes'
parallel or nearly so to the axle of the machine: these brushes are connected by
gears and chains to, and so are driven by the axle of the machine in the ordinary
or any convenient manner: I pivot a lever or levers to the frame of the machine
and connect the back end of this lever or levers to the metal frame which carries
the brushes the front end of this lever has a wheel or friction bowl which comes in
contact with a cam secured to or made with a countershaft connected to and
driven by the axle, to lift the brushes and leave the dirt or rubbish in heaps on the
road. Instead of cams and levers other suitable mechanism may be employed to
raise the brushes. I connect a movabe scraper to the machine so that it may act
upon the road in front of the brush or brushes when desired.
.
I employ levers and clutches that may be operated from the drivers seat to
throw the brushes in and out of gear. I fit the clutch on a long bush which
extends through the boss or hub of the wheel.

page_text: I John Barrow, of 8 Oldham Road, Miles Platting in the County of Lancaster,
Mechanic, do hereby declare the nature of said Invention for IMPROVEMENTS IN
MACHINES FOR SWEEPING STREETS AND ROADS, 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 machines used for sweeping streets and
roads, and the object of my improvements is to construct a machine that will
brush the dust, dirt, mud, snow or refuse into heaps instead of leaving it in rows,
which are at present swept into heaps by men.
In performing my Invention I employ a frame preferably of metal which is free
to oscillate on the axle of the machine or other centre and balanced by weights (or
in other convenient manner) secured to the frame at the front of the machine; in
a bracket or by hangers, secured to this frame at the back of the machine I fit a
revolving brush or brushes at an angle of about forty five degrees, or more or less,
and in another bracket or by hangers, a second revolving brush or brushes, parallel
or nearly so to the axle of the machine: these brushes are connected by gears and
chains to and so are driven by the axle of the machine in the ordinary or any
convenient manner: I pivot a lever or. levers to the frame of the machine and
connect the back end of this lever or levers to the metal frame which carries the
brushes, the front end of this lever has a wheel or friction bowl which comes in
contact with a cam secured to or made with a countershaft connected to and driven
by the axle to lift the brushes and leave the dirt or rubbish in heaps on the road.
Instead of cams and levers other suitable mechanism such as a crank may be
employed to raise the brushes;
I employ levers. and clutches that may be operated from the driver's seat to
throw the brushes in and out of gear.
:
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being bad to the figures and letters marked, thereon:
Fig. 1 is a plan and Fig. 2 a side view of my improved machine for sweeping
streets and roads and Fig. 3 is a side view of the bracket and metal frame on
which the latter is fulcrumed.
a is the ordinary wood frame of the machine to which are secured the shafts b;
c is the metal frame pivoted to and free to oscillate on the boss d¹ of a bracket d
bolted to the frame; the axle e to which are secured the wheels e¹ passes through
the bracket d the movable balance weights fare secured to one end of the frame c
to the other end of which are secured the brackets or hangers c¹ and c² in bearings
in which are fitted the revolving brushes g and g¹ respectively the latter of which
is parallel to the axle e and the former at an angle of about forty five degrees:
the bush g is driven from the axle e on which is fitted a clutch one half of which h
is keyed or secured to the axle and the other half h¹ is free to slide on the axle and
carries a chain i which passes over and drives a chain wheel secured to one end of
a stud j mounted in bearings in the bracket c¹; at the other end of the study is a
bevel pinion k which gears into and drives a bevel pinion 7 secured to the shaft of the
revolving brush g: the brush g' is also driven from the axle e by means of a clutch,
one half of which m is keyed or secured to the axle e, the other half is formed
with a spur wheel m¹ and is free to slide on the axle: when the two parts are
moved into gear with one another the wheel m¹ gears with a pinion n secured to a
stud o carried in bearings in two brackets o' secured to the frame c: a chain

page_text: wheel p is secured to the other end of the stud o and connected by a chain p' with
a similar chain wheel p² secured to one end of a stud o² carried in bearings in
brackets o³ secured to the frame c: at the other end of the stud o² is fixed a chain
wheel which is connected by a chain q' with a chain wheel q³ secured to the end
of the shaft of the revolving brush g'. The clutches h¹ and m³ are connected by a
forked rod, not shown in the drawings, which is actuated from the driver's seat by
a lever, also not shown, pivoted to the rod and to the frame a: by moving the
lever the driver can slide the clutches and m¹ into or out of gear with the
clutches h and m and so give motion to the brushes g and g¹ or stop them from
revolving as desired. The shaft of the ordinary revolving brush of the
machine is fitted and driven as usual from the spur wheels keyed to the axle e.
The double lever t is connected by an adjustable hanger t¹ (or by a screw) to the
back end of the frame c and is pivoted to a bracket to secured to the frame a: a
friction bowl u is fitted in bearings formed near the front end of the double lever t:
a spur wheel is secured to the axle e and gears into and drives a spur wheel w
fast on a shaft x supported in bearings ¹ on the frame a: a cam y is also secured
to the shaft x and as the latter revolves the can y comes in contact with the bowl u
and so depresses the front end of the double lever tand causes the back end to raise
the frame c and with it the revolving brushes g and g¹at every revolution of the
cam y. Any suitable means such as a wedge or slide may be employed to hold
down the front end of the lever t when depressed in order to keep it out of reach
of the cam y and the bushes g and g¹ clear of the ground.
When the rubbish has been swept into rows by the ordinary long brush the
brush is raised from the ground by the driver in the usual manner. The wedge or
other device is then moved to release the lever t and allow the frame c to lower
the brushes g and g¹ to the ground. The clutches h¹ and m' are moved into gear
with the clutches h and m in order to cause the brushes g and g' to revolve and
sweep the rows of rubbish into heaps.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed
I declare that what I claim is-
1.-Sweeping rows of dirt mud or other rubbish into heaps and the machine for
effecting the same, substantially as herein shown and described..
2. The revolving brushes g and g¹ substantially as and for the purposes herein
shown and described.
