1 Claim. (01. 15-220)
My invention relates to a window cleaning de
vice and more particularly to certain improve
ments in a window cleaning device as disclosed in
my co-pending application, Serial No. 60,27 9, ?led
5 January 22, 1936.
It is an object of the invention to ‘provide a
window cleaning device which is very simple, light,
yet rugged in construction, easy to manipulate,
and effective for window cleaning purposes.
It is another object to provide a window clean
ing device of the character more fully set forth
in my said co-pending application, with an im
proved means for movably connecting the two
arms and for manipulating the same relatively
15 to‘ each other.
l5 on one arm (in this case what is in effect the
arm 5) or that part of the arm 6 to the right of
the break 12 and which is rigid with the arm 5.
The extension member l5 may be attached to the 10
arm 5 as by means of screws IS.
The extension
member l5 passes the hinge pin l3 and extends
along and in spaced apart relation to the nor
mal position of the arm 6. Thus it will be seen
that the extension member l5 and adjacent part 15
of the arm 6 may be grasped in the hand and
Other objects and various features of inven—
tion and novelty will be hereinafter pointed out
since the extension member I5 is preferably rigid
or will become apparent to those skilled in the
from the frame 5 to, say, the dot-dash line posi
tion of Fig. 1. If it is desired to hold the arm 20
6 in the dot-dash line position, the latch mem
art upon a reading of the speci?cation.
In the drawing which shows, for illustrative
purposes only, a preferred form of the invention
Fig. 1 is a view in elevation of a window clean
ing device illustrating features of the invention;
Fig. 2 is a view in elevation of the device shown
rating point l2 occurs, whether in the arm 6 or
the arm 5 or in the bottom of the generally
U-shaped form of the arms, it will be seen that
the arms are hingedly connected to each other.
In order to manipulate the arms I provide a 5
member preferably in the form of an extension
in Fig. 1, taken from the top.
As has been more fully set forth in my afore
said co-pending application, the window cleaning
device includes a pair of arms having window
cleaning devices, such as sponges, at the ends.
These arms are adapted to- be separated to per
mit one cleaning device to be applied to each side
of the same window pane and are preferably co
extensive with and opposite each other.
with the arm 5, the arm 6 may be drawn away
ber I1 provided on the arm 6 may be moved so
as to overlie the end of the extension l5 and
thus hold the arms separated so that the sponges
or other devices 9 may be applied and removed. 25
When'the arms are in such separated position,
the device may be moved into position over a
window frame, the latter of course passing be
tween the two arms 5--B. Even if the arm 6 is not
latched to the arm 15 when it is desired to apply 30
the device to a window, the extension l5 and arm
6 are merely grasped so as to separate the two
arms sufficiently to permit the window to pass
between the pads. When the device has been ap

having pad holding boxes or the like l-B at the
M which is of the desired strength will ?rmly
35 free ends. Each box may hold a sponge 9 or
. press the pads 9-9 onto the window pane with
other cleaning, washing, drying or polishing de
vice.‘ The two arms in the preferred form are
made of aluminum comprising a relatively wide
plate member l0 having a substantial rib ll
40 thereon for strengthening purposes. The arms
ars thus very light and yet are exceedingly
strong and are preferably quite rigid. When the
arms are relatively rigid they are hinged to
gether so as to be movable relatively to each
In the form shown the arm 6 is divided at l2
and the two parts are hinged together as by
means of a hinge pin l3 passing through appro—
priate ears on the two parts of the arm, as will
be understood. A‘ spring 14 of desired and ap
propriate strength serves to urge the arm Gyto
just the desired force and the window cleaning
device may then be moved back and forth so as
to wash, clean, dry, or polish the window. In 40
order to facilitate movement of the device over
the window I preferably provide a substantial
and convenient hand grip I8 on one of the arms
(in this case the arm 6).
Thus a person stand
ing at the inside of a window may without the
necessity for reaching out or hanging over the
window sill wash, dry and polish both sides of a
window pane. The space between the arms is
unobstructed to the bottom of the bend so that for
a given reach of the arms the device may be of
ward the arm 5 so as to press the two'pads 9 to
wardeach other and onto the opposite sides of
a window pane. ‘Regardless of where'the sepa-_
minimum length.
While the invention has been described in con
siderable detail and reference is hereby made to
my said co-pending application for a fuller de- 55

scription of the advantages of a window cleaning
device of the general type herein disclosed, it is
to be understood that various changes may be
made within the scope of the invention as de
?ned in the appended claim.
I claim:
In a window cleaning device, a U-shaped arm
member having one long leg and one short leg‘,
a second arm hinged to said short leg and extend
10 ing to the end of said long leg, a spreader mem
ber rigidly secured to said short leg and extend
ing along the outside of said second arm and
spaced therefrom, spring means at the hinge to
urge said long leg and said second arm toward
each other, and latch means to coact with the end
of said spreader member and second arm for
holding said parts together and said second arm
and said long leg spaced apart against the force
of said spring means.
