CLEANING DEVICE Filed March 16, 1929 Patented June 3, 1930 UNITED STATES PATENT orrics GEORGE H. SUMMER-FIELD, OF CLEVELAND, OHIO CLEANING nnvron Application filed March 16, 1929. Serial No. 347,533.

This invention relates to improvements in devices for" cleaning windows, woodwork and the like and has for an object to provide a reservoir, a moistener and a squeegee combined in a compact unitary assembly in which the moistener and the squeegee are disposed relatively to the reservoir and to one another for most convenient use.

Other purposes are to provide a reservoir of such construction that it may be produced cheaply, easily and quickly from sheet material and which, in its completed form, will be stiff and sturdy even though the material troin whichit 1s io-rmed 1s relatively thin; to provide means for securing the-squeegee to the reservoir in such manner" that it is maintained firmly connected with the reservoir yet is capablefof quick, convenient detachment therefrom; to provide simple, convenient means for 'operatively mounting the moistener on the reservoir, and, in general, to provide a complete device of the type mentioned which is simple in construction, inexpensive to produce, strong,

durable and thoroughly reliable and efiicient in use. p

lVith the foregoing and other purposes in view, the invention consists in the novel features of construction, combination and arrangement of parts as willbe hereinafter more fully described,illustrated in the ac;

con'ipanying drawings and defined in the" Fig. 3 is a detail sectiono-n the' line of Figure-1; and

Fig.4.- is a fragmentary section onthe line y I e surfaces adjacent to a surface being cleaned y to the drawings in detail, it will be observed thatthe present device comprises a reservoir A, a moistener B and 1.tof Fig. 2.

.Referring now a squeegee C. I

.Reservoir A which ma 1 beformed from and the end closures 11,

iew of al cleaning the lips and through the moistener;

section takenfice'm Y By reason of the moistener -being larger any suitable material into any desired size and shape, preferably is formed from sheet metal and is of somewhat elongated form and'of substantially semi-cylindrical crosssect'ion. It consists of a body portion 10 and end closures ll, 11, body portion l0 preferably being pressed froma single blank of material to include, in cross-soction, a flat lower side 12, a curved upper side 12-3, and a pair of spaced parallel lips 14, 11 constituted by the longitudinal marginal edge portions of said body, extending outwardly from one side of portion 13 adjacent to the flat lower side 12 thereof.

The marginal end portions of body 14) are turned outwardly to provide flange 11 which are of cup like or dished formso as to lit into body 10 thereby to reinforce and stiffen. same, have their -marginal" portions 16 crimpecl over said flanges whereby the end closures are rigidly secured to the body in water-tight relation thereto,

Moistener B which may beformed from any suitable absorbent material such as lclt,

' sponge rubber or the like, preferably is" somewhat longer than reservoir 1%., of 'uch thickness as to ht when conipress'seu *between the} lipsld, 14 and of a width to ertend any suitable distanceoutwardly lJGyUllil the free edges of said lips when the inner edge thereof is engaged against the adjacent edges of the end closures 11,11. Said moistener is adapted to be detachably secured be tween the lips 14, let-in the relation stated in any suitable or desired manner, for example, as shown, by means or: a series 05- bolts 17en a -ed throu h alined o enin than the reservoir A the projectingend por tions 18 of the moistener provide guards preventing end portions of the reservoir from contacting with and perhaps marring replaced whenever occasion demands.

Reservoir A is adapted to contain water or other oleaningliquid and since the inner 1 face of moistener B is exposed to water or other liquid contained within the reservoir it is manifest that due to capillary attraction the moistener will be maintained wet so long as suiiicient liquid remains in the reservoir to wet the inner face of the moistencr. A filling opening 19 is formed in the res rvoir at any desired point and this opening may be maintained normally closed by any suitable form of cap or plug 3 preferably a cork or rubber stopper indicated at 20. The said stopper 20 is provided with a hollow plug 20, slidable in a central opening in. the stopper so that the vent opening 20 therein may be opened. and closed by the shifting of the plug. The said plug is preferably flared at its inner end as indi ated at 20 and its outer end .is formed with a head or finger engaging nob 20. The purpose oi? the vented plug 20 is to permit the water holding chamber to be vented to the atmosphere and permit free flow of water to the moistener B. \Vhen the plug is pushed in the stopper to cover the vent opening 20" water cannot, of course, leak out of the chamber and likewise the chamber is cut oil from the atmosphere. On the other hand when the vent is uncovered water may freely flow through the moistener B.

Squeegee C which may consist of an elongated strip of rubber or other pliable material 21 stiffened along its inner edge by a strip of metal 22 of substantially U-shaped, outwardly tapering cross-section, is adapted to be secured to the reservoir'body at any suitable point along the side thereof oppo site to the moistener B, and to this end an elongated channel member 23 having the same or approximately the same cross-section as the reinforcing strip 22, is riveted, soldered or otherwise rigidly secured to the body 10 to receive the reinforced inner edge of the squeegee. An outwardly bowed leaf spring 2% is disposed within member 23 and when the squeegee is engaged within said.

of body 1.0 is a threaded member 25 over.

or into which is adapted to be threaded a handle or handle socket 26 for manipulating the device. 7

In the use of the device moistener B is adapted to be employed initially to wet and to some extent clean a surface such as a window, while squeegee C is adapted subsequently to be employed to wipe the surface clean, the relative arrangement of the elements B and C as shown and described enabling the respective operations to be performed conveniently Without necessitating any material angular alteration of the position of the handle 25 with respect to the surface being cleaned, and the shape of reservoir A and the disposition of the squeegee adjacent to the fiat lower face thereof assuring that the inoistener will remain damp or wet so long as substantially any liquid remains in the reservoir.

From the foregoing description considered. in connection with the accompanying drawings, it is believed that the construe tion an d the advantages of the present device will. be clearly understood. It is desired to point out, however, that the structure shown may be modified in'various respects within the spirit and scope of the invention as defined in the appended claims.

1. A device of the character described comprising a body member, a squeegee having converging side portions, means for connecting said squeegee with said body mem ber comprising a channel member carried by the body member and having converging sides to receive therebetween the converging side portions of the squeegee, and a leaf I spring within said channel member adapted to exert pressure against the squeegee to maintain the converging side portions thereof in engagementwith the converging sides of said channel member.

2. In a device of the character described,

a reservoir, a porous moistener carried by said reservoir adapted to be supplied with liquid therefrom, said reservoir having a filling opening, a stopper for said opening, and a tube slidably mounted in said stopper, said tube being closed at its outer end, open at its inner end, and provided with a lateral opening adapted. to be covered and uncovered by sliding movement of said tube relative to the stopper to admit or deny he ontrance of air into the reservoir.

' 3. In a device of the character described, a supporting body, a member carried by said supporting body having a channel of less width at the outer side than at the inner side of the member, a squeegee having a portion of greater width than the least width of said channel disposed within the latter, and spring means urging said squeegee portion in the direction oi the portion of least width of said channel to maintain the iqueegee in assembly with said channel memrer.

In testimony whereof I hereunto ai-Qix my signature.

GEORGE H1 SOBIMERFIELD.
