Im- PROVED MACHINES FOR SWEEPING STREETS AND HIGHWAYS
Year: 1873

page_text: LETTERS PATENT to William Greenwood, of Keighley, in the County
of York, Machinery Agent and Engineer, for the Invention of "Im-
PROVED MACHINES FOR SWEEPING STREETS AND HIGHWAYS."
Sealed the 15th August 1873, and dated the 17th February 1873.
PROVISIONAL SPECIFICATION left by the said William Greenwood
at the Office of the Commissioners of Patents, with his Petition,
on the 17th February 1873.
I, WILLIAM GREENWOOD, of Keighley, in the County of York,
Machinery Agent and Engineer, do hereby declare the nature of the
said Invention for "IMPROVED MACHINES FOR SWEEPING STREETS AND HIGH-
WAYS," to be as follows :—
This Invention relates to machines for purpose above recited and has
for its object the construction of such machines in such manner as to
remove the dirt or refuse from the surface of the street or road to a

page_text: tank or receptacle attached to the machinc, the latter being of the fol-
lowing construction:-I employ an axle on which are mounted two
wheels (on which the machine travels by horse or other power) between
which wheels is swung from the said axle a tank or receiver for the dirt
or debris. One of the said wheels is constructed with a broad flange,
and within the flange are a number of dishes or concave receptacles
into which the dirt is swept by means of a circular brush working at an
angle to the said receptacles, a guard being applied to further direct the
dirt to the said receptacles. As the wheels revolve the dirt is carried by
the receptacles formed within the flange thereof, and is discharged over
and into a trough leading to the tank above referred to and is thus col-
lected.
The mechanism for driving the brush consists of spur gear
fixed on the axle of the wheel. Intermediate wheels communicate the
rotation to a pinion, the latter carrying a peg or star wheel, a like wheel
being keyed on the shaft of the brush, and a chain working over this
star wheel communicates from the pinion the necessary rotation to the
brush. The brush is supported by means of two radiating arms from
the axle, to the other ends of which arms a link is attached, and the
other end of each link is attached to the shaft ends of tho said brush, so
as to admit of the necessary rising and falling motion of the brush
caused by incqualities of surface over which the brush must travel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Greenwood in the Great Scal Patent Office
on the 16th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GREENWOOD, of Keighley, in the County of York, Machinery Agent
and Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Greenwood, Her special
licence that I, the said William Greenwood, my executors, adminis-

page_text: trators, and assigns, or such others as I, the said William Greenwood, my
executors, administrators, and assigns, should in any time agree with,
and no others, from time to time and at all times thercafter during the
term therein expressed, should and lawfully might make, use, exercise,
3 and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVED
MACHINES FOR SWEEPING STREETS AND HIGHWAYS," upon the condition (amongst
others) that I, the said William Greenwood, my executors, or admi-
nistrators, by an instrument in writing under my, or their, or one
) of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the samo was
to be performed, and cause the same to be filed in the Great Seal Patent.
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Greenwood, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Sheets of Drawings,
that is to say:-
This Invention relates to machines for purpose above recited, and has.
for its object the construction of such machines in such manner as to
remove the dirt or refuse from the surface of the strect or road to a
tank or receptacle attached to the machine, the latter being of the fol-
lowing construction:-I employ an axlo on which are mounted two
3 wheels (on which the machine travels by horse or other power) between
which wheels is swung from the said axle a tank or receiver for the dirt
or "debris." One of the said wheels is constructed with a broad flange,
and within the flange are a number of dishes or concave receptacles,
into which the dirt is swept by means of a circular brush working at an
angle to the said receptacles, a guard being applied to further direct the
dirt into the said receptacles. As the wheels revolve the dirt is carried
by the receptacles formed within the flange thereof, and discharged over
and into a trough leading to the tank above referred to, and is thus col-
lected. The mechanism for driving the brush consists of spur gear
and a connecting link or links. The brush is supported by means of two
radiating arms from the axle, to the other ends of which arms a stud

page_text: the same, and so as to admit of the necessary rising and falling motion
of the brush caused by inequalities of surface over which the brush
must travel.
Such being the nature of this my said Invention, I will now proceed t
to explain the same in detail and for the purpose of clearly illustrating
the same, I have hereunto annexed two Sheets of Drawings, and have
marked the same with letters of reference, the same letter referring to
the same part in the various views or Figures.
A is an axle on which are mounted two wheels B and B' (on which 1
the machine travels by horse or other power), between the wheels is
swung from the said axle the tank or receiver C for the dirt or "debris."
The wheel B' is constructed with a broad flange, and within the flange
are a number of dishes or concave receptacles D into which the dirt is
swept by means of the circular brush E working at an angle to the 1
receptacles D, a guard or shoe F being applied to further direct the dirt.
into the said receptacles. As the wheels revolve the dirt is carried by the
receptacles D and discharged over and into a trough F¹ leading to the
tank and is thus collected. The mechanism for driving the brush E
consists of spur gear G and the wheel H on the axis of the brush E. 2
The brush is supported by means of two radiating arms J, J, the other
ends of which arms are connected by the collars and stud K. A link M
is attached to the shaft end M' supported by the arms M³ so as to admit
of the necessary rising and falling motion of the brush caused by
inequalities of surface over which the brush must travel, and for the 2
purpose of transmitting motion to the said wheels G and H, the link M
receiving its rotation through the agency of the catch box N. At P is
shewn a circular brush for sweeping close to the curb stone or causeway
edge, rotation being imparted thereto by the link Mand bevel gear R, T,
the link being changed from its connection at S to the point W.
Having thus fully described the nature and particulars of this my
said Invention, and shewn by Drawings and description thereof the
manner in which the same is to be or may be performed or carried into
practice, I would have it understood that I claim the construction and
use of the wheel B' in combination with the brush E, together with the 3

page_text: brush P, as and for the purpose herein fully described, set forth, and
shewn in the Drawings.

In witness whereof, I, the said William Greenwood, have here-
unto set my hand and seal, this Eleventh day of August, in the
year of our Lord One thousand eight hundred and seventy-threc.
