Description
(54) APPARATUS PRIMARILY FOR USE IN CLEANING WINDOWS
(71) I, JOHN ARTHUR REED, a British subject, of 50 Burgh Road, Gorleston,
Great Yarmouth, Norfolk, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to an apparatus primarily for use in cleaning windows.
According to this invention there is provided an apparatus for cleaning windows or similar surfaces comprising an elongated channel member with longitudinal edges provided with flexible strips, the channel member housing a number of discharge nozzles to direct a spray of liquid towards the open face of the channel, a conduit connected through a pump to a liquid supply tank from which liquid is fed to the nozzles, valve means selectively directing the liquid to either the nozzles or to a return conduit leading back to the supply tank, and a suction line communicating with the channel for removal of liquid caught in the channel.
In such an apparatus the flexible strips along the edges of the channel form a squeegee to remove the cleaning liquid, generally water, from the window glass.
The liquid is then drawn-off by the suction created inside the channel. The apparatus includes a water supply unit having a pump for supply of water under pressure to the nozzles in the channel member, constructed as a cleaning head, and preferably a suction producing means also connected with the head by a flexible ducting which may also house the water 'feed conduit. The water is advantageously fed continuously to a manually operated valve associated with the cleaning head which normally allows feed water to return back through a water return conduit to a water tank in the supply unit. Operation of the valve causes water to be fed to the nozzles for cleaning purposes. The suction conduit may be arranged at its water supply unit end to discharge water drawn-off through the channel in the head into a return tank. The return tank can be arranged to replenish the water tank as and when required through a filter unit thus providing continuous recycling of the water.
Filter means may be provided in the outlet of the liquid supply tank.
The nozzles in the head will preferably be adjustable to produce the required spray patterns.
An embodiment of the invention is shown by way of example in the accom- panying drawings also illustrating further preferred features and in which: Figure 1 shows schematically a cleaning head and a water supply unit associated therewith,
Figure '2 shows the cleaning head in cross-section with spray nozzle dismantled,
Figure 3 shows the water control valve,
Figure 4 shows the apparatus schematically with an extension unit for cleaning second floor windows,
Figure 5 shows a section of an extension unit,
Figure 6 shows a schematic view of a second water supply unit from one side,
Figure 7 shows the unit of Figure 6 from the other side, and
Figure 8 shows a detail of the end of the flexible hose.
Referring to Figure 1 the apparatus comprises a cleaning head unit 1 and a water supply unit 2 interconnected through a flexible convoluted suction conduit 3 which encloses a water feed conduit 4 and water return conduit 5. The cleaning head 1 has a handle 6 provided with a water control valve 7 which normally connects conduit 4 with conduit 5 whereby water under pressure supplied by a pump 8 from tank 9 is fed back to the tank at 10. This allows the pump to run continuously and the water to circulate. Operation of the valve 7 causes the pressure water to be fed through the pipe 1!1 to one or a series of nozzles 12 located within a channel 13 and arranged to direct a spray in the direction 14 onto a window 15.
The top and bottom edges of the channel 13 are provided with rubber strips 16 and 17 forming blades. The lower blade 1 serves to prevent water running down the
window and the upper blade 17 assists in
the production of a vacuum within the
channel and achieved by suction applied to
the conduit 3 from suitable means pro
vided in the unit 2. The suction producing
means is conveniently powered from a motor also driving the water pump. Water
drawn-off from the head 1 is discharged
from the suction conduit 3 in a separation
chamber 18 and is collected in a return
water tank 19. The vacuum is applied to
the tank 19 through an orifice l9a.
The return tank 19 is connected to the
supply tank 9 through a filtering means
such as a cartridge filter and when the level
in tank 19 reaches a predetermined level
set by a float mechanism 20 water is trans
ferred to replenish the tank 9. This tank
includes a valve means such as a ball-cock
9a which closes when the tank is full to
prevent water being sucked back to tank
19 as the level therein falls.
The cleaning head 1 is shown in section
in Figure 2 and each spray nozzle 12
(shown dismantled) is connected to a mani
fold 12a fed by the pipe 11 from valve 7.
Water drawn-off by the suction flows in
direction A down through the handle to
the conduit 3. The nozzles 12 may be ad
justable, to achieve the required spray
pattern.
Figure 3 shows the valve 7 which has a
manual trigger 7a controlling two poppet
valves 7b and 7c. Valve 7c normally closes
the feed to pipe 11 and valve 7b allows
water from feed conduit 4 to pass to return
conduit 5. When the trigger is pressed the
state of the valve is reversed and water
from conduit 4 is fed to the pipe 11.
The handle of the cleaning head may be
adapted so that several sections can be
coupled together for cleaning windows at
higher levels and Figure 4 shows an ar
rangement wherein two additional sections
of handle 6a and 6b are provided between
the cleaning head 1 and the valve 7 to in
crease reach to enable second floor windows
to be cleaned. Figure 5 shows one such
section wherein the tubular extension 50
has an internally threaded socket 51 and
an externally threaded spigot 52 whereby
a number of such sections may be connec
ted together, the socket of one section en gates the spigot of another. Sealing means
such as O-rings may be included to provide
a seal for the vacuum. The water conduit
provided in each section has a tapered
socket 53 and tapered plug 54 each retained
by spiders 55 concentricallv and connected
by a flexible tube 56. This arransement provides coupling of the conduit when the 'sections are joined together. Any slight
water leakage at the conduit joint is not
imnortant.
The float mechanism 20 (Figure 1) is arranged so that the outlet to the filter is blocked when tank 19 is empty. The float also cuts-off the vacuum when the water level rises due to blockage of the filter preventing water flowing therethrough to tank 9.
The apparatus provides an effective method of cleaning windows or similar surfaces using high pressure water jets without substantial wastage of water and is thus self contained.
Figures 6 and 7 show a generally similar apparatus from the used return water tank side and feed water tank side respectively.
The motor unit A, which can be electrically powered or an internal combustion engine drives a water pump B and a suction producing unit C. The pump B draws water from an inlet D in the base of the feed water tank E and passes it to the outlet F (conduit 4) under pressure. The unused return water (conduit 5) is discharged back through G into tank E. The vacuum hose 3 communicates with a box H opening into the used return water tank I which is subject to a vacuum produced by unit C. The tank I has a valve unit J comprising a vertical channel with a ball float
K and arranged to be movable between a high water level position K1 in which the vacuum duct connection to unit C is blocked, this is to prevent water being drawn into said unit should the level rise too high due to a blocked filter, and a low water position K2, in which the duct to a cartridge filter L is closed when the water level falls too low whereby the suction is prevented from acting on the filter.
The feed water tank is equipped with a ball cock M which opens the outlet side of the filter L when the water level is less than a prescribed maximum.
Figure 8 shows in detail the end of the convoluted hose 3 with the water valve 7 and connection for either the head or extension tubes.
