WKNDQW-ULNKNG DEVICE.

ltnnlteotion tied litter in, 19%. Serial Ito."7l3,ttt.

To all whom it may concern:

lie it known thet I, then B. Gnnnrn a citizen ot the United @totes, residing; et Se nttle, in the counte of lting end State 0t lt ashingrton, hove invented at certain new end uset'ul ltnnrovement in Window-mouninn Devices, of which the following is a specification.

My invention reletes to improvements in windowcleeninn devices end the object of my invention is to provide at window cleaninn; device thnt embodies e liquid receptecle hnvine on one side thereof o relatively long r gorous clennin strip through which liquid inoy he einittefslowlv tor moistening e sur thee thot, is to he cleoned end having disposed on enother side it long tlenihle squeegee strip "tor drying the surtoce thet hes heenclenned with the liquid.

Another ohject is to provide it window elennine; device heving n liquid receptecle thot is provided with or pump end cheek tnlre ineens by which liquid they he pumped.

into the reoeptocle end hy which eir preslnn the etinospheric pressure y no nonintoined in the .receptuele to h v torce the liquid through the porous clowning}; ot not desired rote.

ltnother oh ieot is to provide window clowning}; device in whieh the liquid will not "ordinnrily diseherge or lenlt troni hut will only he torced through the-eleening strip hy the eitcess uir pressure in the reeentoele when the device is in use.

Another ohjeet is to provide window clowning device ennhodyine; porous oles-n inn niede tr-oin two strips oil telt or other suitohle nonterinl hotween whioh disposed at lower oi bristles, the nod hristles heing seeurely clonnped hetween two rigid side iolotes.

li urther ohjects ore to provide o window eleoning device thet is sirnnle' etlieient end durohle in constnnetion neot onto nientol in omoeorenoe, inennensive to instintoeture end convenient to use will sews time end tether.

it eccoinphsh these oh eote hy devices illus trnted in the ncconinnnying drewings, wherein Figure l is it view in plain end Fig. 2 is a sectional view of the minetaken on line 2, 2 of Fig. l, ports heing' shown in elevation; and

Fig. 3 is n. troginentery sectional view on an enlarged scnle illustrnting ode-tail ot the hrush and pad construction.

Referring to the drowings throughout which like reference numerals indicete like parts, l have shown it reletivelv long recentecle or housing 5 hnving o hnndleshonh ti rigidly secured thereto midweyhetween its two ends and extending nt right ninm les therefrom. it tnhulnr hondle niernher is threaded into the end ot the hondle shonlr 6 end serves we or pump cylinder.

Disposed within the hnndle mernher "l is recip'rocehle piston 8 eonnected with n pin ton rod 9 thet extends outwordly throunh the outer end oi the hnndle 3' end is rigidly secured to e cup-ll which tornio n hood hold by which the piston they recigoroceted.

'i he pump cylinder hy the hondle 7 communio with short nine it is disposed w hin d connected w W l3 tends lengthwise no i one reoeptne. tlne end ot the pine outt provided with oheoh: l lthnt will innit liquid to snid pine hut will L tr vent liquid t oni "flowing nine. The other end oi" the nine provided with o ehec rolve l5 which will "p "tnit the disoherge o ioni'd into reeen Lil hut will not permit liquid he drown lttttt't the reeentecle 5 into the pump eylinder.

:he "note it hes odroin nnoningg closed e screw one to end enid renew tecle h w nrovided on the trout side one with engulorly disposed hrooltet hetween which squeegee in ruhher or other suitnhle ninteriel is securely clumped hjy holts or rivets ill.

The recentnole h is provided the other front eorner with disposed henchet goletes 2t) hetween which n clowning pod is'seeurely clnrnped ns hgr rivets or-holte hi, the nod pre erehly heing rnede no of two strips 232 oi felt or siiniler ehsorhent rentel loetween' which ere inter ooee hristles shown in it.

litrtmltets end till diverge other sutostnn telly es s; own in i d it thnt when device is tn'rned one the ltltl) pad will be conveniently applied to a window for cleaning and when the device is re-' versed the squeegee strip 18 may be conveniently applied to the window for drying the same.

In the operation of my window cleaning device when the receptacle 5 is to be filled the end of the receptacle in which the pipe 13 terminates is immersed in liquid and the pump piston 8 is drawn outwardly in the cylinder 7 thus causing liquid to be drawn in through the tubes 13 and 12 into the cylinder 7. The pump piston 8 is then moved inwardly forcing said liquid out past the check valve 15 into the receptacle 5. This operation is repeated until sufficient liquid is pumped into the receptacle 5. The filling of the receptacle 5 creates sufficient pressure therein to force enough liquid out through the cleaning pad to thoroughly moisten said pad and to render the same ready for use.

In cleaning a window the cleaning pad is first drawn over the glass, the felt pad members 22 moistening and washing the glass and the bristles 23 loosening any dirt that may tend to adhere to the glass. After this has been ,done the cleaning device is reversed and the squeegee 18 is drawn over the glass in a well known manner to remove the moisture and dirt that is left thereon.

The rate of discharge of liquid through the pad is governed by the pressure within the receptacle 5 and said pressure may be increased at any time by operating the pump. This makes it possible to construct the pad so that the device will not leak but so that liquid may be forced outwardly therethrough at any desired pressure within the receptacle.

The pad formed of a layer of bristles between two layers of felt constitutes a very efficient cleaning device, the felt serving to support the bristles and the bristles serving to clean the glass and removing any spots or dirt that tend to adhere thereto.

The foregoing description and accompanying drawings clearly disclose what now consider as a preferred embodiment of the invention but it will be understood that this disclosure is merely illustrative and that 'such changes may be resorted to as are within the scope and spirit of the invention.

V hat I claim is 1. A cleaning device of the class described embodying a liquid receptacle, an elongated cleaning pad carried by said liquid receptacle and having one edge subject to contact with liquid within said receptacle, a handle on said receptacle, and manually operated pump means disposed with said handle for filling said receptacle and for producing a pressure in said receptacle to force said liquid out through said pad.

2. A window cleaning device embodying an elongated liquid receptacle, an elongated cleaning pad carried by said receptacle and having one edge subjected to contact with liquid in said receptacle, a rigid tubular handle extending at right angles from said receptacle, a reciprocable piston in said tubular handle, a tube extending lengthwise within said receptacle and terminating in one end thereof, a check valve for permitting liquid to enter at the outer end of said tube and conduit means connecting said tubular handle with said tube.

3. A window cleaning device embodying a liquid receptacle, a cleaning pad carried by said receptacle and having one edge subjected to contact with liquid in said receptacle, a rigid tubular handle extending at right angles from said liquid receptacle, reciprocable piston-in said handle, a tube extending lengthwise within said receptacle and terminating in one end thereof, a check valve for permittingdiquid to enter at the outer end of said tube, another check valve for permitting liquid to discharge at the inner end of said tube, and conduit means connecting said handle with said tube between said check valves.

in witness whereof, I hereunto subscribe my name this 10th day of May, A. D. 1924.
