This invention, as indicated, relates to a surface cleaning device.. More particularly, it comprises a unitary structure embodying means for applying a lm of moisture to a surface and hav- 5 ing a rubbing or squeegee device which may thereafter be utilized to distribute such liquid over the surface and to remove the dirt and excess moisture from such surface. It is not intended to limit the device to cleaning purposes,

1o as it may be found of advantage in spreading liquid or coatings of various kinds over extended surfaces, and may be adaptable for distributing material in powdered form in an even layer, under special circumstances. However, the.

15 principal use for said device is for window cleaning purposes, both for household use and for automobiles and the like.

The principal object of the present invention is to provide a simple self-contained surface Q cleaning device which may be made of rubber throughout, and which will serve to supply the liquid necessary for the removal of grit and dirt from the surface and in the same device provide a squeegee or similar means for removing such g softened grit and dirt and excess moisture from the surface.

Another object of the invention is to provide an article having a reservoir for cleaning material, preferably in liquid form, with a means carried by the same device for spreading such liquid and removing the excess thereof, together with the accumulated grit and dirt from such surface.

Another object of the invention is to provide 3, a receptacle, preferably formed of rubber, having one or more compartments within the interior thereof which may contain a soapy liquid mixture and clear water, respectively, in separate compartments, with means for selectively dista; charging either of said mixtures upon a surface and distributing the same over the surface and thereafter squeegeeing such surface to free the same from the mixture so applied and any accumulation of grit and dirt on such surface.

Another object of the invention is to provide an article, preferably constructed entirely of rubber, having one or more compartments therein for the reception of cleansing and rinsing fluid, embodying a self-filling construction and o special discharging features, including a valve control responsive to the position of the device in connection with the surface operated on.

A further feature of the invention comprises the provision of a holder for a sponge rubber 55 element, such holder being provided with a squeegee attachment, and also having means for automatically forcing the liquid from the sponge rubber, together with resilient means for supporting such sponge rubber and assisting in the discharge. of liquid therefrom. 5

Other and further features of the invention will appear in the course of the following description.

As is clearly shown in Figures 1 to 5 of the drawings, the preferred form of construction comprises a receptacle I, which may be formed of any suitable material, such as molded rubber, but which also may be formed, if desired, of light metal with elastic walls. The device, however, is preferably formed of rubber with a substantial degree of elasticity, and may have roughened outer wall surfaces to provide rubbing surfaces to remove material adhering to the surface operated on, and is provided adjacent one edge with a combined squeegee and valve element 2 which is of triangular cross section and is preferably a separate strip vulcanized or otherwise suitably fastened to one side of the receptacle adjacent the edge, with the angular portion of the squeegee engaging over the adjacent face of the receptacle and covering a series of apertures 3 passing through the wall thereof and entering a compartment 4 within which cleansing fluid may be received.

Adjacent the opposite longitudinal edge of the side of the receptacle, a strip of sponge rubber 5, or rubber of suitable consistency for removing compacted material from a surface, may be attached by vulcanizing or fastening in any other suitable manner, or may be formed integrally with the article itself. The interior of the receptacle may comprise one single compartment or the same may be divided into two Separate receptacles 4a, 4b, as is more clearly indicated in Figure 2, wherein a heavy central web 6 extends substantially the length of the receptacle along a central longitudinal line. When such central division is provided, one receptacle may serve as a container for soapy liquid or other cleansing fluid, and the other compartment may serve as a'receptacle for clear water for rinsing purposes. As indicated, the receptacle itself should have elastic Walls so that the filling of the reservoirs or chambers within the same may be accomplished by compressing the chamber preliminary to inserting it in a basin of liquid with the valves held f ree, whereby liquid may be drawn or sucked into the interior of the device.

As is more clearly shown in Figure 3 vof the drawings, the discharge orifices 3 for the receptacle preferably comprise a series of very small ports arranged adjacent one marginal edge of the receptacle, over which one face of the triangular combined squeegee and valve member is adapted to closely seat. Internal ribs 1 may be provided within the compartment for stifening the top and bottom walls thereof and to prevent adhesion of the interior surfaces in the event the liquid employed should be of a somewhat sticky consistency.

After iilling the device in the manner explained, the use of the same against the surface 8 to be cleaned is shown in Figures 4 and 5. As is shown in Figure 4, the device is being moved downwardly over a window surface with a valve member 2 tilted to free the valve ports 3 so that pressure upon the top and bottom walls of the receptacle will force cleansing liquid from the interior of the device against the adjacent surface to be cleaned. The sponge rubber mem ber 5 is shown as in contact with the surface in advance of the iiuid discharge orifices and serves to distribute such fluid over said surface when lightly passed thereover.

The angular position of the device toward the surface to be cleaned may be changed so as to biing the sponge rubber membera little more forcibly against the surface after the same has been fully moistened so as to dislodge any iirmly adhering particles from the surface. After the application of the iiuid and the dislodging of firmly impacted material from the surface, the squeegeeing of the surface is brought about by reversing the device and applying the squeegee edge to the surface in the manner shown in Figure 5. It will be noted that in this position the squeegee is forced against the end of the receptacle having the orices and such orifices are more firmly sealed when the device is thus moved downwardly in operative position.

When a two-compartment apparatus is used, the operation just described is performed first with the soapy mixture on one side of the device, and thereafter the other compartment is used by reversing the device and clean water is applied over the surface and the surface is again squeegeed to remove all excess moisture and to finally clean and polish the surface.

In place of having a flat face against which the combined valve closure and squeegee element bears to seal the discharge orifices, the discharge orifices may at their outer ends lie within a shallow groove Il, as is shown in Figure 6, on the exterior surface of the receptacle, and the adjacent face of the valve Sealing element may have a rounded bead I2 to correspond with the curvature of said groove and thus provide a more secure closure of the discharge orifices owing to the compression of the rib l2 within such groove and the more firm adherence of the same against the adjacent wall of the container.

The forms of construction of the apparatus shown in Figures 7, 11, 13, and 15 may be formed in molds or may be extruded, if desired. In each of said structures the squeegee and valve elements are shown as integrally formed with the receptacle for the cleansing iiuid. In the event the device is made by extrusion, the ends may be plugged and sealed in any Suitable manner by vulcanizing end walls thereto.

The structure shown in Figures 7 to 9 preferably lis formed with a channel 2| extending along one surface thereof within whicha strip of sponge rubber 22 is embedded, and adjacent which a series of valve ports 23 is provided adapted to be closed by the overhanging edge 24 of the squeegee element 25 which, as stated, is preferably formed integrally with the receptacle 26. It will be noted that the squeegee element has an angular forward face' 2l and an extension flange 24 overhanging the forward edge of the receptacle, and bearing against the valve ports at a point closely adjacent'the sponge rubber insert.l When the device is to be used for applying moisture to a surface, the action of the construction is illustrated in Figure 8,v wherein the integral overhanging valve closure is raised from valve-sealing position by contact with they adjacent surface to be operated on, and permits the free ow of liquid under thepressure upon the top and bottom walls of the Areceptacle outwardly against the surface to be cleaned. After the liquid so discharged against such'surface has been distributed thereover andv the surface is ready for the squeegeeing operation, the device is reversed and is rapidly moved over the surface .to be cleaned, carrying with such lm of liquid the grit and dirt which has been softened through the applicationof the liquid.

In Figure l1, the receptacle 3l may be formed of extruded material, as stated, but in place of using a large overhanging valve closing member, the valve closure comprises a thin lip 32 adapted to bear against an adjacent substantially rigid extension edge 33 and to seal the structure against discharge of liquid. Such sealing device is in direct line withthe discharge ports 34 from the interior 35 of the receptacle and the liquid may be readily discharged by slight pressure upon the top and bottom walls ofthe receptacle.

When the device is moved upwardly against the surface, as shown in Figure 12, the ports will be unsealed and liquid may be forced through the discharge openings against such surface. The integrallyy formed squeegee 3E on the opposite endof the apparatus may be used for the final cleansing operation or the substantially rigid edge 33 adjacent the valve ports may be used for such squeegee operation.

When the squeegee on the opposite-side of the receptacle is used, an opportunity is afforded to tightly grasp the members on the other side of the receptacle and thus manually hold the sealing elements together so as to prevent accidental discharge of liquid during the squeegeeing process.

The structure shown in Figures 13 and 14 may likewise be of extruded material and while in a measure such device is similar to the device shown in Figure 11, it illustrates a different type of valve and closure therefor, the closing flap for the valves being a relatively thin member 4l adjacent the top surface or in line with the top surface of the receptacle 42 and the valveports i3 being formed through a substantially rigid member 44 extending longitudinally of the central portion of said side adjacent thereto. The valve sealing flap therefore completely covers the outer end of the discharge port and may be held firmly thereagainst by the grip of the Aoperator in the usual course of using the squeegee element 45 on the otherl side of the receptacle.

`In Figure 14 the action of the device in discharging'fiuid against the surface being cleaned is shown, it being understood, of course, that suitablepressure is applied to the top and bottom Walls of the container to bring about the discharge of such fluid.

The structure shown in Figure may be extruded, and shows a relatively heavy body 5l of solid rubber having a suitable degree of elasticity with the rearward portion of such body being formed integrally so as to provide a cylindrical receptacle 52. The thickened body portion may be formed at one edge with a channel 53 within which is preferably embedded a sponge rubber moisture-applying element 54 against which bears the valve sealing element 55 formed integrally with the body and being in effect an overhanging depending flange of rubber bearing against a series of ports 56 parallelly arranged beneath the same and extending into the interior of the receptacle. The outer face 5l of the body portion is beveled so that when the device is moved downwardly against the surface, the valve closing flange will be lifted to permit the free discharge of the contents of the receptacle under the pressure of the hand of the operator upon the cylindrical portion of the device. When the device is bodily reversed, the edge formed by the meeting line of the outer surfaces at substantially right angles to each other provides the squeegee element 53 which when moved downwardly in reverse position is forced into valve sealing position and thus prevents any discharge of incisture during the squeegecing strokes of the apparatus.

The device shown in Figures l5 to 17, when made of extruded material, is preferably sealed at one end by inserting a suitably shaped plug 59, preferably of rubber, and vulcanizing thc same in such end and inserting in the slightly projecting end opposite thereto an annular ferrule Sl, having screw threads 62 on its exterior surface and having a series of folded prongs 63 shown as of substantially triangular shape at its inner side and adapted to be clampingly engaged upon the free edge of the cylindrical receptacle which projects beyond the body portion of the device. The ends of the triangular elements may be turned inwardly to form gripping points and struck-up tongues 5d may be formed at intermediate points on the triangular inner members shown to more securely attach the threaded ferrule to the cylindrical receptacle. A suitably threaded cap member E5 carrying a sealing washer of suitable material (not shown) may be utilized to seal the receptacle against leakage of the cleansing fluid placed therein.

When a receptacle of the character just de scribed is utilized, it is possible to use the apparatusfor distributing heavy mucilaginous material over a surface or for using material of heavy consistency, such as liquid wax. The .receptacle also may be filled with a powdered material and obviously would be suitable for mothproong operations whereby pulverized naphthalene could be ejected through the ports of the receptacle into upholstery fabrics by moving the same thereover in one direction with the valves open, and by moving the rubbing edge of the device over` such a surface after such pulverized material has been ejected thereon, the material could be forced into the fibres of the fabric. In place cf a rubbing edge, a brush attachment (not shown) may be provided to distribute the mothproofing powder through the fibres of the fabric.

A skeletonized form of apparatus is shown in Figure 19, asubstantially rigid body member 1l being provided with a recess openingat one side thereof through a channel 12 of reduced cross section in which a strip of sponge rubber 13 is secured. The body portion which receives the sponge rubber may be formed of any suitable material, but preferably is formed of molded rubber having sufficient degree of elasticity to permit the compression of the sponge rubber by the fingers of the operator when firmly applied to the free edges thereof. It may be made substantially rigid, however, if desired, and an auxiliary platelike member 14 formed of rubber or other suitable material may be provided to bear against the sponge rubber in slightly spaced relation to its outer edge, whereby pressure of the sponge rubber against such element or pressure brought by forcing said element against the surface in advance of the sponge rubber will serve to discharge liquid from the sponge rubber element. The device is preferably formed with a squeegee attachment 15 secured to one side of the body member and projecting beyond the rearward edge thereof. This element may be formed integrally with the platelike member contacting with the sponge rubber strip.

If desired, fastening pins (not shown) may beV used to secure the sponge rubber against accidental dislodgement from the recess and such fastening pins may also hold or assist in holding the squeegee element and the resilient moisturedischarging element in position against the side of the body member.

A still further modified form of construction is shown in Figures 20 and 21, wherein the liquid receptacle is in the form of a cylindrical member 8l and wherein the discharge orifices comprise a series of ports 82 extending only partially through the heavy wall of said receptacle. Said ports are preferably formed at spaced intervals at the bottomV of a channel or recess 83 provided on the inner wall of the cylindrical receptacle to permit free flexing action of said Wall at such point for a purpose presently to be disclosed. A slot 84 cut longitudinally in the outer wall of said receptacle in alignment with the series of shallow ports or passageways intersects the extreme ends of said ports and serves as a sealing means for such ports when the natural cylindrical contour of said receptacle is maintained. Upon inward deformation of the sides of said receptacle, as shown by the arrows in Figure 21, the lips 85 formed at either side of said slot which extends partially through the wall of said receptacle in alignment with said ports are drawn apart, as is shown in Figure 21, and thus open such ports and permit the pressure exerted upon the sides to eject the liquid contents through said ports and slot. Release of said pressure immediately seals said ports and the inherent resiliency of the structure maintains such ports closed under a high degree of elastic pressure, so that substantially no leakage will occur through the normal use of the squeegee member. Said squeegee member 8B is preferably integrally formed with the cylindrical member along one side thereof, and preferably spaced at a position ninety degrees from said discharge slot. The gripping action of the hand of the operator upon the cylindrical member at points on either side of the squeegee tends to more firmly hold the ports closed, and therefore this additional pressure will entirely prevent any leakage of moisture through the discharge ports during the squeegeeing operation. The ends of the cylindrical structure are preferably sealed by means of rubber plugs which may be inserted as at 81 therein and vulcanized in position, such plugs being relatively thin-walled and of elastic composition which permits the compression of the cylindrical member.

While a number of forms of the apparatus have been described, the arrangement and combination of the various elements is by no means intended to be exhaustive, and the extent and position of the valve and squeegee elements with reference to each other, aswell as the particular position and shape thereof, may be widely varied in accordance with the special purposes for which the device is intended to be used, as well as such considerations of cheapness of manufacture and the requirements of quantity production operation. The reservoir may be made as an attachment, and, as such, or as a complete device, may be used as part of a power operated windshield Wiper.
