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 

[Price 2/-! 


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
