A New or Improved Window Oleaning Apparatus.
I, SAMUEL KLEEMANN, of Kattowitz, Upper Silesia, in the German Empire,
Merchant, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to a new or improved apparatus for cleaning windows.
The accompanying drawings to which I will liereinafter refer illustrate the
improved apparatus in front view in Figure 1: in cross section in Figure 2:
and in horizontal section in Figure 3. Figure 4 represents one of the cleaning
pads or cushions:
The apparatus is more especially intended for use with shop windows where
the component parts may be arranged in positions in which they are not visible
when out of use.
Pivotted one in each corner of the window frame are four bars of angle iron
or the like a, c, d, e, of such dimensions that no part of the window can escape
being rubbed by one or other of them when they are moved through angles
of 90°. That side of each bar which is nearer the window pane is covered with
cloth or other suitable material so as to form a pad b which comes into contact
with the glass. By the movement of the different arms, therefore, the window
may be rubbed and cleaned in every part.
.
Opposite arms may be suitably connected together so that motion imparted
to one is communicated to the other or to the others. This may be effected by the
employment of the devices illustrated in the drawings.
As shown, cand a are connected together by means of a chain which passes
around chain wheels secured to their shafts. d and are similarly geared
together. When the bar a is moved from its vertical position downwards to the
left, the bar e moves downwards from its horizontal position to the right. Upon
the return of the bar a the bar e also returns. Bars and e similarly work in
conjunction with one another.
Motion may be communicated to the parts a and c by means of a crank handle g
secured upon a shaft h. An extension i from this handle or from the shaft
carries a link the other end of which engages with a slot 7 formed in an exton-
sion of the bar a.
The movement of the crank through one revolution thus causes the bar a
to move outwards to a horizontal position and back to a vertical position, corre-
sponding motion being imparted to the bar c through the connecting chain.
A similar device may be employed for operating the second pair of bars, or
this second pair may be so connected to the first that the movement of one handle
operates both pairs of bars.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
Annaratus for cleaning windows consisting of bare nivotted in the corners of

page_text: the window frame and provided with pads, the bars being so connected together
that the motion of one is imparted to one or more of the others, constructed
arranged and operated substantially as liereinbefore described and as-illustrated
by the accompanying drawings.
