apparatus has assumed its lowest position and the inside of the window a has been
completely cleaned and coated with liquid by the sponge, the rubber strip 9 spreads
the liquid in a uniform manner and wipes it off. For this purpose it must be
pressed against the inside of the window; this is effected by the adjusting piece
striking against a lower projection w which moves it gradually out of the notch t¹
of the screw t, and thereby renders the bar with the rubber cleaning strip 7 free
to be acted on by the spring u, which presses the strip q against the inside of the
window. If desired, the moistening of the sponge m with a special liquid can be
dispensed with, and the sponge may be employed only for the purpose of rubbing
the window panes, whilst the rubber cleaning strip serves to give the final cleaning.

COMPLETE SPECIFICATION.
Means for Cleaning Windows and the like, and for Preventing the
Deposition of Moisture and Frost thereon.
I, VICTOR STEGEMANN, of Burgerstrasse 18, Göttingen, Hanover, Germany,
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 means for cleaning windows and the like and for
preventing the deposition of moisture and frost thereon.
The apparatus I employ comprises a frame adapted to be moved over the entire
inside surface of the window and provided with receptacles to respectively contain
sponge and the liquid which is to prevent the deposition of moisture and frost on
the window and to assist in cleaning the said window. The frame also carries a
cleansing strip or squeegee of india rubber, the arrangement being such that on
downward movement of the frame (which is suspended after the manner of a roller
blind) the sponge which is saturated with the cleansing fluid comes into operation,
whilst on the ascent of the apparatus the india rubber cleansing strip comes into
action.
When not in use, the apparatus is suspended at the top edge of the window.
The drawings filed with my Provisional Specification illustrate apparatus
according to my invention,
Fig. 1 being a front view,
Fig. 2 a vertical section, and
Fig. 3 a horizontal section on the line A B of Fig. 1.
:

page_text: Figs. 4 and 5 illustrate the device for throwing the india rubber cleansing strip-
out of action, arranged at the upper edge of the window,
Fig. 4 being a longitudinal section through the window, on the line C D of
Fig. 5 and
Fig. 5 a plan of Fig. 4.
Figs. 6 and 7 illustrate the apparatus in a middle position, in which the sponge.
is operative, whilst the india rubber cleansing strip is inoperative,
Fig. 6 being an elevation, and Fig. 7 a cross section.
Figs. 8, 9 and 10 are respectively a cross section a front elevation and a plan of
the projection for placing the rubber cleaning strip out of action.
c is a frame suspended inside the window a by means of bands bb; it extends the.
whole width of the window and carries at its upper part the receptacle d for the
cleansing liquid, and at its lower part the bar f which carries the india rubber
cleansing strip, the sponge receptacle e, being arranged between the receptacle d
and the bar f. The frame c which is maintained horizontal, is by means of
pulleys g g and h and the band i drawn up and down in a well known manner along-
the inside surface of the window a. The frame c is guided on the window frame :
by means of guide rollers k. The receptacle e is open at its front portion which is
directed towards the inside of the window, and is furnished with suitable material
such as a sponge m that is capable of taking up moisture and of distributing it in a
uniform film or layer upon the window. Above the receptacle e is situated the
liquid receptacle d which is also of the full width of the window, and is provided
throughout its length with a number of small apertures n through which the cleansing
liquid drips onto the sponge. The cleansing liquid employed may consist either of
spirit (such as spirit of wine) or glycerine or a mixture of such substances. The-
sponge m is pressed, with a gentle pressure, against the inside of the window a by-
weak springs o that are arranged between the receptacle e and the frame c, and the
action of which can be regulated as desired by means of the nuts p. The arrange-
ment of the bar for the india rubber cleansing strip q, is such that the rubber
strip is moved away from the window when the apparatus is being lowered, and is.
pressed against the inside of the window on the ascent of the apparatus and after-
the sponge m has passed over the whole inner surface of the window. For
facilitating the throwing into and out of operation of the india rubber cleansing-
strip q there is arranged at the upper end of the window in the vertical groove
formed by the frame 1, a projection r which strikes against pins & on the bar f,
Figs. 4 and 5. The bar f which is adjustably arranged on the frame c so as to be
capable of moving relatively thereto, is held by set screws t, and is pressed by
springs u between the guide cheeks cc¹ of the frame c and of the bar f, against.
the window. The screws t are each formed at t¹, Fig. 5, with a notch in which the
adjusting piece v, pressed by the spring is capable of entering when the bar f,
with the screws t, is gradually moved back by the action of the projection or
abutment r. The screws t and consequently also the bar will then be effectually held
in such a position that the india rubber cleansing strip q will not then bear against.
the inside of the window a. When the apparatus has assumed its lowest position
the inside of the window a will have been completely cleaned and coated with liquid
by the sponge. The india rubber strip q then comes into action and serves to first
spread the liquid in a uniform manner and then to wipe it off. For this purpose it
must be pressed against the inside of the window; this is effected by the adjusting
piece v striking against a lower projection w which moves it gradually out of the
notches t¹ of the screws t, so as to thereby render the bar f with the india rubber
cleansing strip 9 free to be acted upon by the spring u, which then presses the
strip q against the inside of the window. If desired, the moistening of the sponge m
with a special liquid can be dispensed with, and the sponge may be employed only
for the purpose of rubbing the window panes, whilst the india rubber cleansing
strip serves to effect the final cleaning operation.

tion and in what manner the same is to be performed I declare that what I
claim is :-
.
1. In cleaning windows and the like and for preventing the deposition of moisture
and frost thereon, apparatus comprising a horizontal frame c adapted to be moved
over the inner surface of the window to be treated and held by bands b b i, and a
receptacle e for material such as a sponge, this receptacle being arranged to be pressed
gently against the inside of the window by means of springs o substantially as
herein described.
2. Apparatus of the kind referred to in the preceding claim constructed with a
perforated receptacle d for containing liquid for moistening the sponge m in the
sponge receptacle e substantially as described.
.

the reception of an india rubber cleansing strip 9 substantially as described.
4. Apparatus of the kind referred to in Claims 1 and 3 in which the bar f and
india rubber strip q are arranged in such a manner that by means of a lateral
projection the said strip will be moved away from the surface of the window the
