5 Essex, both British subjects, do hereby
declare the nature of this invention to be
us follows: — ... 1
This invention relates to clettuin^ de-
vices and has for its object to provide a
10 device which can be used to clean both
sides of u window without the cleaner
having to go from the inside to the out-
side of the window, or vice versa. .
A device according to the present m-
15'vention comprises a hollow or U-shuped
member in which is si dably mounted a
cleaning material l^^^HH"*'! I'^T^u^r
locking the member and holder together
in any desired axial co-relationship, the
20 hollow member l)eing r)pen at one end
and adjacent this end being slotted to
allow part of the holder to pass there-
through so that the said holder can be
locked either in axial prolongation w^th.
25 or at an angle to, the said member. Fre-
ferablv the hollow member is in t^^o
parts pivotally connected together so
that the said member may be extended
in length when desired. Preferably also
30 the hollow member is of channel section,
whilst the holder may be m strip form
slotted throughout the greater portion ot
its length to allow the locking means
which may consist of a clamping screw
36 to pass therethrough. The cleaning
material which may be m the form of a
duster, wash leather or the like is pre-
ferably secured in the holder by means
of a spring clip or jaw. If desired, the
40 holder may be formed of a rod bent upon
itself in the form of a TJ, the spring
iawed clip being secured across the tre«
ends of the U. The said spring jaws may
conveniently consist of two plates to one
45 end of one of which* is secured one end
of a strong leaf spring, the other end
being secured in the neighbourhood of
the mid-position of the other plate, which
being such that the spring nonual y 50
tends to keep one end t)f one plate firmly
in contact with one end of the other
plate. , . ,
The U-shaped member which as pre-
viously stxited is of channel section is 53
.slotted adjacent one end, which is left
open so that when the holder is slidden
within the U-shaped member so that the
device is fully extended the holder can
pivot and the end thereof remote from qq
the spring clip can protnide through the
.slot in the U-shuped member thereby
allowing the holder to be slidden across
the U-shaped member to any desired
position in which it can be clamped by 65
the clamping screw, which may have a
butterfly nut to co-operate therewith.
According to the dimensions of the slot
so the angle at which the cleaning
material is presented to the window can 70
be varied. The U-shaped member at the
end remote from the slotted end may
have pivotted thereon another U-shaped
member of slightly less length than the
first, the two memliers being foniied 76
with cr)-operating dimples whereby when
the second member is moved about its
])ivot it can come into locked engage-
ment with the first U-shaped member to
form a prolongation thereof. When, 80
however, the second member is moved
out of locking engagement about its
pivot it is so arranged that it can col-
lapse onto the first member thereby form-
ing a portion which closes the open part 85
of the channel or U-shaped member.
It will thus be appreciated that there
is obtained n cleaning device the length
of which may be varied as desired by the
holder being slidden within the U-shaped 90
mem1>er wliicb forms the handle by which
the device is gripped, and locking the
holder in any required position whilst
tlie angle at which the cleaning material
can be presented to the window with 95
respect to the handle can be varied by
