In Figs. 9 to 12 wehave illustrated a modified into the sharp 'form of the invention which is particularly adapt-l j ed for window cleaningyalthough it may con'- providing resilientisupport andv at the same time acting as aV reservoir for water which will be expelled through the perforations 32 andat the .sides ofthe cleaning element upon the applicaveniently be used for general cleaning purposes. y

A rectangular block member 22 is providedat its respective ends with horizontal slots 23 and 24,V

corresponding substantially in placement to the slots H and I2 of the first embodiment, and along the forward surface of the b loclrthere is provided a slightly upwardly inclined slot 25 extending` ber block member is simply retained in place by between the slots 23 and 2li. Within the slot 2t.

there is engaged one end of aflexible cleaning strip 26, secured by nails l2l driven upwardly from the under-side of the block 22 through the portion of the strip inserted in the slot 23, the

strip being carried beneath the block 22 in substantially spaced relationthereto and its other end being engaged in the slot 24 and secured by nails 28 driven downwardly from the upper side of the block 22 through the portion of the strip engaged in the slot 2li. engaged in the slots 23 and-24 are cut away at their forward extremities as at 25J, so that these extremities will be substantially flush with the base of the slot 25, and will, therefore,` not inter-1 fere with the engagement in the slot 25 of the,

longitudinally extending squeegee element 'v 30,'

which is secured therein by'a series of nails 3l, j driven upwardly from the under-side ofthe block Y 22 through the portion of the squeegee element engaged in the slot 25.

The cleaning element 26 and squeegeeelement 30 are both constructed of the same bias cut flexible rubberized woven fabric material as the corresponding elements of theffirst embodiment, and the cleaning element 26 is provided with a series of perfonations 32, preferably arranged in staggered rows. An'inclined ,pole handle 33 is engaged Aat its screw threaded end 34 in a threaded hole (i5l in the block member 22 and extends in opposite directionV to the sgueegee element. It will be understoodthat ifdesired the squeegee element may be provided at one end of the block member in similar arrangement to The ends of the stripV tion of Vpressure thereto. lt `will be understood of course that any other material having these properties may be employed. This sponge rubits own expansiorpressure so that it may be readily ldisengaged for the! purpose of cleaning and lfilling it with water.

We have illustrated andv described preferred and satisfactory embodiments of the invention,

vbut it will be understood that changes may be madetherein, within the spirit and scope thereof, as dened in the appended claims'.

Having thus described our invention, what we claim and desireto secure by Letters Patent is:

i. In a cleaning implement, a supporting block. member, and a cleaning element'disposed at its under-side comprising a flexible resilient strip of material of substantial thickness having spaced end portions thereof secured to said block and an intermediate portieri projecting downwardly therefrom in the form of a yieldable resilient loop, open at its longitudinal sides, said loop portion having perforations in itsprojected surface, the Walls of which are at an angle to the pro jected surface, said -perorations being in cemmunication at the inner side of said strip with said open longitudinal sides to allow'flow of water between said perforations and said open sides,

the longitudinal edges of said strip and the edges Vof said perforations adapted to move in engagethat shown in the first embodiment, in which casey the pole handle would extend in opposite direction thereto and longitudinally of the block member. 'f Y Whereas the series of 'convex cleaningl portions of the member I3 of the rst embodiment of the invention are resiliently Vsupported'b,1 the concave corrugations secured bythe nails Il, which arrangement imparts sufficient inherent stiffness to the kcleaning portions to maintain them in projected relation while allowing them` to flex under pressure, the cleaning element .-26 y is resilient supported in projected relation with` respect tothe block member 22 by an inserted ment Withtlie surface being cleaned as the strip is compressed-and iiexed through reciprocatory movement of the blockmember under pressure. 2. In a cleaning implement, a supporting` block vmember, and a cleaning element disposed at its under-side comprising a strip of flexible resilient material of substantial` thickness having spaced end portions thereof secured to said block and an intermediate portion projectingY downwardly therefrom vin the ferm4 of a yieldable resilient loop, operfat its longitudinal sides, said loop portion having perforations in itsprojected surface,

' said perforations being incommunication at the inner side of said strip with said open longitudinal sides to allow flow of water between said perforations and said open sides, the walls ofwhich are at anangle to the projected surface, and a flexi the edgesof saidperforations adapted toY move ble resilient water absorbing and expelling insert member engaged between said block member and said projected loop portion of said strip, and removably therefrom through said open `longitudinal sides, the longitudinal edges of said strip and Yinengageinent with the surface being cleaned as resilient block 36. This block is preferably formed of sponge rubber, which has the property of the strip is compressed and flexed through reciprocatory movement of the block member under pressure.
