`it caused
`the present
`improvement
`to be de
`vised.
`.
`Referring
`to
`the drawing,
`ét and 5 desig
`nate
`the
`two sections
`of the
`improved
`nozzle,
`each
`of which
`is
`provided
`with
`inclined
`and rounded walls
`having
`diverging
`sides
`with
`iianges
`6, which when brought
`into
`register
`with
`each
`other,
`form
`a
`tapering
`chamber
`7 which
`gradually
`merges
`into
`a
`flat wide mouth 1l
`in a front wall
`8 formed
`by
`relatively
`thick
`flanges
`on
`the widest
`part
`of each
`section’.
`The sections
`are also
`formed with
`semi-cylindrical
`extensions
`9
`at
`their
`inner
`ends
`so
`that when brought
`together
`a
`cylindrical
`neck
`or nipple
`is
`formed by which
`the nozzle
`is secured
`to
`the
`discharge
`pipe
`10 of
`the
`flushing
`cart
`or
`wagon
`in any well
`known manner.
`The
`front
`walls
`of
`the
`sections
`are
`recessed
`on
`their
`dividing
`lines
`to form a wide narrow
`discharge
`opening
`11, and said
`recesses
`are
`gradually
`deepened
`toward one side
`to form
`said
`discharge
`opening
`of
`gradually
`-in
`creasing
`depth
`from one
`side
`to
`the
`other.
`rl‘hus when the device
`is
`in operation
`a flat
`tened
`stream
`of water
`of
`increasing
`volume
`in
`cross
`section
`is
`discharged
`therefrom,
`which
`preserves
`its
`_solidity
`throughout
`its
`flushing
`area.
`In other
`words,
`the water
`strikes
`the pavement
`with
`equal
`force
`for
`the
`entire
`width
`of
`the
`stream.
`The
`sec
`tions
`are
`secured
`together
`preferably
`with
`screws
`12, and it will
`be understood
`that
`if
`desired
`suitable
`packing may be inserted
`be
`tween
`the
`sections
`to prevent
`leaking.
`Pre
`vious
`to
`securing
`the
`sections
`together
`the
`walls
`of
`the chamber 7 are highly
`polished,
`which
`renders
`the
`delivery
`of
`the water
`more
`effective.
`Thus
`the
`advantage
`vof
`forming
`the nozzle
`in sections
`can be clearly
`seen. Nozzles
`of
`this
`type
`are usually
`positioned
`to discharge
`the
`stream
`from a point
`near
`the wagon
`to a distance
`from
`the wagon,
`and by
`forming
`the
`discharge
`mouth
`of
`gradually
`increasing
`width
`from one side
`to
`the other,
`the widest
`portion
`the mouth
`of
`being
`adapted
`to
`throw
`the water
`the
`greatest
`distance,
`the volume
`of water
`dis~
`charged
`will
`retain
`its
`solidity
`or
`force
`throughout.
`Having
`thus described
`the
`invention,
`what
`is claimed
`is :_
`1. A íiushing
`nozzle
`formed
`in
`sections,
`each of which comprises

`0 all whom 'it
`Be it known
`that
`I,
`Iî-IANsoN ROBINSON,
`a citizen
`of
`the United
`States,
`residing
`at
`South Bend,
`in
`the
`county
`of St.
`Joseph
`and State
`of Indiana,
`have
`invented
`certain
`new and useful
`Improvements
`in Flushing
`Nozzles,
`of which
`the
`following
`is a speci?
`cation.
`.
`in
`This
`invention
`relates
`to
`improvements
`flushing
`nozzles
`of
`the
`type used on flushing
`wagons which
`are mainly
`employed
`for
`washing
`city
`pavements,
`and has
`for
`its
`particular
`object
`to provide
`a 'device
`of
`this
`character
`that
`will
`discharge
`a
`flat
`broad
`stream
`at an angle
`to
`the pavement
`and
`means
`causing
`said
`stream
`to
`contact
`for
`with
`the
`pavement
`with
`equal
`force
`throughout
`its
`flushing
`area.
`A further
`object
`to provide
`a nozzle
`is
``formed
`of separate
`sections,
`whereby
`its
`in
`terior
`can be polished
`to make its
`discharge
`"With
`the above and other
`objects
`in view,
`the present
`invention
`consists
`in
`the combi
`nation
`and arrangement
`of
`the parts
`as will
`be hereinafter
`more
`fully
`described,
`shown
`in
`the accompanying
`drawing,
`and pointed
`out
`in
`the appended
`claims,
`it being under
`stood
`that-
`changes
`the
`form,
`proportion,
`in
`size and minor
`details may be made within
`the
`scope
`of
`the
`claims without
`departing
`from
`the
`spirit
`or sacrificing
`any of
`the ad
`vantages
`of
`the
`invention.

`Nozzles
`of
`this
`character
`are
`especially
`applicable
`to
`flushing wagons provided
`with
`a water
`tank and a tank of compressed
`air,
`by means of which
`the water
`is discharged
`with
`greater
`or
`less
`force,
`and they
`are de
`signed
`t0 project
`a diverging
`stream
`against
`the pavement
`at an inclination
`to wash
`the
`debris
`toward
`the gutters,
`but
`in nozzles
`of
`this
`character
`heretofore
`used,
`the
`force
`of
`the stream
`at
`the point
`of
`its
`greatest
`throw
`is usually
`somewhat
`than
`its
`nearest
`less
`throw.
`This
`is caused by
`the
`resist-ance
`of
`the air which
`tends
`to break
`the
`flat
`stream
`into
`a spray,
`and as
`the
`flushing
`value
`of
`the nozzle
`depends upon keeping
`the stream
`
`more ei'fective.
