I, ROBERT WADsworth, of The Sanitary Implement Works, Thomas Street,
Halifax, in the County of York, Sanitary Implement Manufacturer, &c., do
hereby declare the nature of this invention to be as follows:
This invention has reference to machines for sweeping streets, roads and foot-
paths, and for collecting and removing therefrom the mud, dust, horse dung
or other matter which the machine sweeps up, and the said machines can be
adapted for manual power, animal draught or motor propulsion, also for running
on ordinary roadways or on tramways.
In carrying out my invention, I construct machines for animal or horse draught,
of somewhat similar design to the horse street sweeping machines, which are
now much used by local authorities, but I dispense with the circular brush which
is used with these machines and is usually fixed at an angle of about 45 degrees,
and also the gearing and other necessary fittings for same. Under the axle
of the machine I suspend a box or bin of suitable size, and by means which will
admit of the same being readily attached or detached, also easily raised clear of
the ground or lowered down to the ground. Across the hinder end of the
machine, at right angle therewith, and in rear of the box or bin, I mount a
circular brush in bearings which allow the brush to be lifted up, by suitable
means, sufficiently high to admit of the box or bin previously mentioned, being
put in its place under the axle or taken out when necessary.
By gearing and a chain belt connected with the main axle, on which the
machine is mounted and propelled, I impart motion to the circular brush which
is caused to revolve at a high speed, and as the machine is drawn along the
streets or roads, the velocity of the brush has the effect of sweeping same and
lifting the mud or dust therefrom and driving it into the box or bin.
For help-
ing the mud or dust forward into the bin, the hinder portion of the bottom of
same is hung on hinges and arranged so that the man in charge of the machine,
can when sitting on the driving seat, pull a handle and the same will cause
the hinged part of the bottom to rise up quickly and throw the dirt forward to
the fore end of the bin. When the bin is full of "sweepings "it is then
lowered to the ground, disengaged from the machine and its contents emptied
into a cart or on the tip.
To enable the machine to sweep a wider width and to sweep the channel or
part of streets nearest the footpath, I mount another circular brush, at an angle
of about 45 degrees, in suitable bearings to admit of the brush revolving in front
of the "
near side propelling wheel, and I impart motion thereto, by gearing
and a chain belt connected with the main axle of the machine.

"
When preferred the said brush may be mounted in front of the off side
wheel, instead of the near side ditto as above described, or brushes may he
placed on both sides when required. When the machine is in operation the
foremost or angle brushes deliver their sweepings in line with the hinder brush,

page_text: and the latter sweeps up and collects the same into the bin as the machine. is
drawn along.
For machines for motor propulsion the construction will be as previously
described, but instead of having shafts to yoke, a horse or other animal in, the
framework of the body will be longer to provide accommodation for the motor
which may be electric, steam, oil or other suitable kind, and the machine will
be fitted with four wheels.
"
For hand or manual machines the construction will practically be the same
as the horse drawn machine, but the machines will be of a size and strength
proportionate to manual power.
In adapting my invention to run on tramways I make use of an ordinary
framework with the wheels, springs & axles which are common for electric or
steam tramcars, on the top of which the bodies are built. To one end of same,
which I will call the hinder end, I mount the circular brush which I have pre-
viously described as being at right angle with the machine, and to which I
impart motion by gearing and a chain belt from the main axletree. Instead of
the box or bin for receiving the mud or dust previously described, a portable
bin or body is placed on the framework, or a body is mounted in bearings which
admit of its being tipped sideways for discharging its contents. For raising the
"sweepings" into the body I make use of an elevator of any well-known kind
and which I place between the circular revolving brush and the body at the
hinder end, and as the mud and dust is brushed into a trough at the bottom of
the elevator by the circular brush, the buckets or scrapers on the elevator carries
the same up and delivers it into the body or portable bin.
The circular brush at the hinder end of the machine is of a sufficient length
to sweep across the tramways, and for sweeping the part of streets and roads from
the tram rails to the footpath, circular brushes such as I have previously
described as being mounted in front of the propelling wheels of a horse drawn
machine, and set at an angle of about 45 degrees, are used, which are made of
a suitable length to sweep this part of streets or roads, and motion is imparted
thereto from the front main axletree of the machine, by gearing and chain belts
as previously described.
As the widths which these brushes will have to sweep will vary, the brushes
are so arranged that the angle of same can be quickly varied to adapt them to
the various widths they will have to sweep; means are also provided to enable
the brushes to be swivelled around in straight line with the machine to allow
other vehicles to pass when necessary.
It will be understood that the power required for propelling my tramway
route road or street cleansing machine, will be such, as the towns or districts
purchasing same, have in use for propelling their tramcars.
When the machine is in operation, the foremost or angle brushes deliver
their sweepings in line with the hinder brush, and the latter sweeps up and
collects the same as the machine travels along.
As a modification, instead of the circular brush described herein as being at
the hinder end of these machines, for sweeping up and collecting mud and dust
from streets and roads, a series of brushes like an ordinary hand broom may be
secured on an endless web, mounted in bearings in an inclined position, which
will sweep the roads and convey the sweepings up an inclined plane directly
into the receptacle for holding same. The same mechanism described for impart-
ing motion to the circular brush will be applicable for imparting motion to the
endless web also.

I, ROBERT WADSWORTH, of The Sanitary Implement Works, Thomas Street,
Halifax, in the County of York, Sanitary implement Manufacturer, &c., 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 follow-
ing statement:-
This invention has reference to machines for sweeping streets, roads and foot-
paths, and for collecting and removing therefrom the mud, dust, horse dung
or other matter which the machine sweeps up, and the said machines can be
adapted for manual power, animal draught or motor propulsion, also for running
on ordinary roadways or on tramways.
In carrying out my invention, I construct machines for animal or horse draught,
of somewhat similar design to the horse street sweeping machines, which are
now much used by local authorities, but I dispense with the circular brush which
is used with these machines and is usually fixed at an angle of about 45 degrees,
and also the gearing and other necessary fittings for same. Under the axle
of the machine I suspend a box or bin of suitable size, and by means which will
admit of the same being readily attached or detached, also easily raised clear of
the ground or lowered down to the ground. Across the hinder end of the
machine, at right angle therewith, and in rear of the box or bin, I mount a
circular brush in bearings which allow the brush to be lifted up, by suitable
means, sufficiently high to admit of the box or bin previously mentioned, being
put in its place under the axle or taken out when necessary.
By gearing and a chain belt connected with the main axle, on which the
machine is mounted and propelled, I impart motion to the circular brush which
is caused to revolve at a high speed, and as the machine is drawn along the
streets or roads, the velocity of the brush has the effect of sweeping same and
lifting the mud or dust therefrom and driving it into the box or bin.
For help-
ing the mud or dust forward into the bin, the hinder portion of the bottom of
same is hung on hinges and arranged so that the man in charge of the machine
can, when sitting on the driving seat, pull a handle and the same will cause
the hinged part of the bottom to rise up quickly and throw the dirt forward to
the fore end of the bin. When the bin is full of "sweepings" it is then
lowered to the ground, disengaged from the machine and its contents emptied
into a cart or on the tip.
To enable the machine to sweep a wider width and to sweep the channel or
part of streets nearest the footpath, I mount another circular brush, at an angle
of about 45 degrees, in suitable bearings to admit of the brush revolving in front
of the near side" propelling wheel, and I impart motion thereto by gearing
and a chain belt connected with the main axle of the machine.

When preferred the said brush may be mounted in front of the "off side."
wheel, instead of the near side ditto, as above described, or brushes may be
placed on both sides when required. When the machine is in operation the
foremost or angle brushes deliver their sweepings in line with the hinder brush,
and the latter sweeps up and collects the same into the bin as the machine is
drawn along.
For machines for motor propulsion the construction will be as previously
described, but instead of having shafts to yoke a horse or other animal in, the
framework of the body will be longer to provide accommodation for the motor,
which may be electric, steam, oil or other suitable kind, and the machine will
be fitted with four wheels.

page_text: For hand or manual machines the construction will practically be the same
as the horse drawn niachine, but the machines will be of a size and strength
proportionate to manual power.
In adapting my invention to run on tramways I make use of an ordinary
framework with the wheels, springs and axles which are common for electric or
steam tramcars, on the top of which the bodies are built. To one end of same,
which I will call the hinder end, I mount the circular brush which I have pre-
viously described as being at right angle with the machine, and to which I
impart motion by gearing and a chain belt from the main axletree. Instead of
the box or bin for receiving the mud or dust previously described, a portable
bin or body is placed on the framework, or a body is mounted in bearings which
admit of its being tipped sideways for discharging its contents. For raising the
sweepings" into the body I make use of an elevator of any well known kind
and which I place between. the circular revolving brush and the body at the
hinder end, and as the mud and dust is brushed into a trough at the bottom of
the elevator by the circular brush, the buckets, or scrapers on the elevator carries
the same up and delivers it into the body or portable bin.
The circular brush at the hinder end of the machine is of a sufficient length
to sweep across the tramways, and for sweeping the part of streets and roads from
the tram rails to the footpath, circular brushes such as I have previously
described as being mounted in front of the propelling wheels of a horse drawn
machine, and set at an angle of about 45 degrees, are used, which are made of
a suitable length to sweep this part of streets or roads, and motion is imparted
thereto from the front main axletree of the machine, by gearing and chain belts
as previously described.
As the widths which these brushes will have to sweep will vary, the brushes
are so arranged that the angle of same can be quickly varied to adapt them to
the various widths they will have to sweep. Means are also provided to enable
the brushes to be swivelled around in straight line with the machine to allow
other vehicles to pass when necessary. It will be understood that the power
required for propelling my tramway route road or street cleansing machine will
be such as the towns or districts purchasing same have in use for propelling
their tramcars.
When the machine is in operation, the foremost or angle brushes deliver
their sweepings in line with the hinder brush, and the latter sweeps up and
collects the same as the machine travels along.
As a modification Fig. 7 instead of the circular brush described herein as being
at the hinder end of these machines, for sweeping up and collecting mud and
dust from streets and roads, a series of brushes like an ordinary hand broom
may be secured on an endless web, mounted in bearings in an inclined position,
which will sweep the roads and convey the sweepings up an inclined plane
directly into the receptacle for holding same. The same mechanism described
for imparting motion to the circular brush will be applicable for imparting
motion to the endless web also.
Fig. 1 of the accompanying drawings is a side elevation of a machine con-
structed according to my invention with shafts to yoke a horse in. Fig. 2 is a
plan or top view of the said machine. The letters of reference in both figures
indicate corresponding parts. A is a framework, which may be in wood or iron,
in which the axle B is mounted, and on the ends of same the propelling wheels C
rotate. On the axle B a large toothed wheel D is placed into which two smaller
wheels E and F gear, said wheels being mounted in suitable bearings on the
framework A. On the spindles G and H which carry the wheels E and F two
chain wheels I and J are placed, and by the two chain belts K and L motion is
imparted to the two circular shaped brushes M and N. The circular brush M
is mounted or carried by iron straps O which work on the spindles G previously
referred to, and the straps project beyond the spindles and have a balance
weight P on each. A chain and treadle arrangement Q is employed for raising

page_text: and dropping the brush M as required when sweeping, and for raising the brush
sufficiently high to enable the box or bin, which receives the sweepings, to be
displaced, a small windlass and chain device R is used for this purpose.
The circular brush N is mounted by iron straps S at an angle of about
45 degrees in front of the near side propelling wheel C and the straps work on
the spindle H and wheel nave G2, and motion is imparted to this brush by the
chain belt L and a cross spindle T which has a knuckle joint U. For raising.
and lowering the brush N I employ the L crank lever V, lever and quadrant. W,
coupling rod X, and chain Y.
Although I only describe and shew a brush in front of the near side propelling
wheel I would have it understood that a brush can be placed in front of the off
"side wheel when required or brushes may be placed in front of both wheels if
found necessary. A is the box or bin for receiving the sweepings and which
is suspended under the axle B, at the front end by eccentrics B³ mounted on a
cross bar C2 working in bearings D2 and actuated by a worm and wheel device E2.
The hinder end of the box A2 being suspended by chains, which are connected
to two rollers or drums F placed on the cross bar C².
The means I employ for putting the machine in and out of gear is a double
clutch device H and H for which Letters Patent were granted to me Novem-
ber 14th, 1888, No. 16,508. Fig. 3 is a detail view of the box or bin for receiv-
ing the sweepings and shews the means employed for helping the sweepings
forward to the fore end of the box. A is the part of the bottom which is hung
on hinges, B a pulley, which is mounted on the underside of the lid of the box
by a suitable carrier. C a chain, which is secured to the hinged part of bottom
and passed over the pulley B and has a handle D welded on the other end, and
when the box or bin is in position under the machine, the handle D hangs in
a carrier Z so that the driver can reach it when sitting on the driving seat.
Fig. 4, is a detail view of the cross bar C with the eccentrics Ba. Worm and
wheel device E and drums or rollers Fa. Fig. 5 is a side elevation of a machine
constructed according to my invention to run on tramways which can be adapted
for electric, steam or other traction. Fig. 6 is a plan or top view of the said
machine. The letters of reference in both figures indicate corresponding parts.
A3 is the framework with the wheels and axles B³ and C³ and other necessary
fittings usual with the under carriages of tramcars. D³ is an elevator which
is fixed to the rear end of the framework A3. E³ is the circular brush which
sweeps across the tramway and forces the sweepings into the troughs of the
elevator D³, the same being mounted thereto by iron straps F3 which admit of
the brush being raised from the ground when required. Motion is imparted
both to the elevator D³ and to the circular brush E by the chain wheel G³ on
the hinder main axle H³, gear wheels I³, chain wheels J³, K3 and L³ and chain
belts M³ and N3. 03 is the front circular brush which can be set to any angle,
so that the width it will sweep can be varied. To the fore end of the frame-
work A3 I mount in bearings P and Q³ a cross bar or shaft R³ on one end of
which is a knuckle joint S³ to which the rod or shaft which carries the brush 03
is coupled. Motion is imparted to the cross shaft R³ from the front main axle
by gearing T3 chain wheels U³ and chain belt V3 from which the brush 03
receives motion by the knuckle joint S. For supporting the outer end of the
circular brush 0 a pillar W³ is securely fixed to the framework A³ to which a
small drum or roller X3 actuated by a worm and wheel device Y³ is attached, to
which a chain 7 is applied. The framework A³ is made of a sufficient length
to project forward far enough to admit of a chain A being applied, for setting
and holding the brush 03 at any desired angle. Another chain B being placed
in rear of the brush. Although one brush is only here mentioned and shewn,
I would have it understood that the front brush may be placed on either side,
or that brushes may be placed on both sides.
Although I have not shewn by drawings a machine fitted for motor propulsion,
I would have it understood that the machine represented by Figures 1 and 2,

page_text: only requires a little longer framework in lieu of the shafts, which are shown to
yoke a horse in, to carry the motor and to which a pair of guiding wheels can
be applied.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The construction of a machine for horse draught or motor propulsion,
which will sweep the streets and collect the sweepings without the use of an
elevator, substantially as herein before described and shewn by the drawings.
2nd. The construction and arrangement of a machine to run on tramways for
electric traction or steam power, which will sweep the streets or roads and collect
the sweepings, substantially as herein before described and shewn by the drawings.
3rd. The manner of imparting motion to the fore and hind brushes of said
machines, substantially as herein before described and shewn by the drawings.
4th. The combination of the several parts herein before described and shewn
by the drawings.
