Improvements in Street Sweeping Machines.
I, ROBERT WADSWORTH, of the Patent Wheel, Axle and Waggon Works, Thomas
Street, Halifax, in the County of York, Wheel Manufacturer, and maker of Vans,
Waggons, Sanitary Implements &c. do hereby declare the nature of this invention to
be as follows:-
-
These improvements have reference to a better means for putting the Circular or
Revolving Brushes, used in Street Sweeping Machines in and out of gear with the
propelling wheels of the said machines, from which motion is imparted to the
Brushes, and consists of the application of two Clutches in the following manner -
On the inner side of the wheel naves one half of a Clutch is formed or applied,
and on the parts of the axle which fit against the inner side of the naves, the
other halves of the Clutches are mounted and made to slide on key-ways.
A Clutch Lever is mounted to each of the said Clutches in suitable bearings on
either side of the machine, and as the attendant sits in his driving seat, he can,
by means of these Levers and Clutches engage the Circular Brushes to either or
both the propelling wheels without leaving his seat.
The axle in this arrangement is the ordinary axle as used for Street Sweeping
Machines, and mounted in bearings on the machine in the usual manner, and the
wheels secured thereto in the usual manner, but in a modification of the above the
axle is formed in three parts, all of about equal lengths; the middle part consisting
of a piece of tube of suitable material, and which is mounted on the machine in
suitable bearings so that it can be rotated; the other two parts of the axle are
solid and the inner ends of the same are turned to fit to a suitable distance into
each end of the tube part, and are also mounted to the framework of the machine
in suitable bearings, and on their outer ends the propelling wheels are secured, so
that the wheels and the two outer or solid parts of the axle rotate together.
On the middle or thereabout of the said tube part of the axle, the large Spur
Wheel, which has to drive all the mechanical parts of the machine is mounted, and on
each end of the said tube part, one half of a Clutch is secured.
On the two outer or solid parts of the axle, at the parts nearest to the halves of tho
Clutches on the middle or tube part of the axle, the other halves of the Clutches are
mounted, and made to slide on key-ways.
A Clutch Lever is mounted to the framework of the machine in suitable bearings,
to each of the said Clutches, and the driver can by means of the said Lever and
Clutches; engage the Circular Brushes to either or both of the propelling wheels,
without leaving his seat, and subjecting his hands to any risk.
Hitherto the Circular Brushes in Street Sweeping Machines have been geared to
the propelling wheels by means of a ratchet wheel, (keyed on the axle next to the
inner side of the wheel naves,) and two pawls mounted on the inner side of the wheel
naves; and it has been necessary for the driver to leave his seat to put the machine
in and out of gear, and place his hands in great danger, in so doing.
Dated this Thirteenth day of November 1888.

Improvements in Street Sweeping Machines.
I, ROBERT WADSWORTH of the Patent Wheel, Axle and Waggon Works, Thomas
Street, Halifax, in the County of York, Wheel Manufacturer, and Maker of Vans
Waggons, Sanitary Implements &c. do hereby declaro 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:
These improvements have reference to a better means for putting the Circular or
Revolving Brushes used in Street Sweeping Machines in and out of gear with the
propelling wheels of the said machines, from which motion is imparted to the Brushes,
and consists of the application of two Clutches in the following manner :-
On the inner side of the wheel naves, one half of a clutch is formed or applied, and
on the parts of the Axle which fit against the inner side of the naves, the other halves
of the Clutches are mounted and made to slide on key-ways. A Clutch lever is
mounted to each of the said Clutches in suitable bearings on either side of the
machine and as the attendant sits on his driving seat he can by means of these Levers
and Clutches engage the Circular Brushes to either or both the propelling wheels
without leaving his seat.
The axle in this arrangement is the ordinary axle as used for Street Sweeping
Machines and mounted in bearings on the machine in the usual manner, and the
wheels secured thereto in the usual manner, but in a modification of the above, the
axle is formed in three parts all of about equal lengths; the middle part consisting of
a piece of tube of suitable material, and which is mounted on the machine in suitable
bearings, so that it can be rotated; the other two parts of the axle are solid and the
inner ends of the same are turned to fit to a suitable distanco into each end of the
tube part, and are also mounted to the framework of the machine in suitable bearings ;
and on their outer ends, the propelling wheels are secured, so that the wheels and the
two outer or solid parts of the axle rotate together.
On the middle or thereabout of the said tube part of the axle the large Spur wheel
which has to drive all the mechanical parts of the machine, is mounted, and on each
end of the said tube part one half of a Clutch is secured.
On the two outer or solid parts of the axle, at the parts nearest to the halves of the
Clutches, on the middle or tube part of the axle, the other halves of the Clutches are
mounted and made to slide on keyways.
A Clutch Lever is mounted to the framework of the machine in suitable bearings
to each of the said clutches, and the driver can by means of the said Lever and
Clutches engage the circular Brushes to either or both of the propelling wheels
without leaving his seat and subjecting his hands to any risk.
Hitherto the Circular Brushes in Street Sweeping Machines have been geared to
the propelling wheels by means of a ratchet wheel. (Keyed on the axle next to the
inner side of the wheel naves) and two pawls mounted on the inner side of the wheel
naves, and it has been necessary for the driver to leave his seat to put the machine in
and out of gear, and place his hands in great danger in so doing.
Fig. 1 of the accompanying drawings represents my improvements as applied to the
framowork of a Street Sweeping Machine as first described herein viz.with the
clutch arrangement mounted to the inner side of the propelling wheels. A is the axlo
which extends across the machine and through the propelling wheels B, on each side
of the machine. C are the parts of the clutches which are secured to the inner side of
the propelling wheels B. D are the other parts of the clutches which slide on
keyways on the axle and as these are slided by means of the clutch levers E into the
parts which are secured to the wheels, the propelling wheels and the axle all rotate
together, and the Spur wheel F, been keyed fast on the axle, this rotates also, and
drives all the mechanical parts of the machine.
Fig. 2 represents my improvements in combination with an axle in three parts as
applied to the framework of a Street Sweeping Machine as described herein. G is

page_text: the middle or tube part of the axle which is mounted in bearings H, to the two
middle bars J of the framework and on each end of the tube, one half of a clutch K
is secured. L are the two outer or side parts of the axle, which are secured by their
outer ends in the propelling wheels M. The inner ends of the said axles are inserted
into the ends of the tube part G and these axles are mounted to the framework N by
bearings O.
On the part of the two side axles L which comes next to the tube part G, the
other parts of the clutches S slide on keyways, and as these are slided by means of the
clutch levers P so that they take into the clutches on the tube part of the axle G, on
which the spur wheel R (which drives all the mechanical parts of the machine) is
secured, the machine is put into gear; and by sliding the clutches the reverse way the
machine will be put out of gear.
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
1stly. Fitting Street Sweeping Machines with a Double Clutch arrangement by
which the driver or attendant can gear the axle to one or both of the propelling
wheels, just as desired, so that the axle will rotate with the wheels (by which the
Circular or Revolving Brushes in these machines are put in and out of gear) or,
vice versa, without dismounting from the driving seat or placing his hands in any
danger or risk whatever, substantially as herein before described.
2nd. Making the axletree of Street Sweeping Machines in three parts, substantially
as herein before described.
