Application October 26, 1950, Serial No. 192,203
1 Claim. (Cl. 15--121) This invention relates to a window washing sponge. The invention is more particularly applicable for use in filling stations and the like for washing the windows and Windshields of automobiles.
It is usually necessary to wash the windows and wind- I shields with a sponge, after which the surfaces are dried by means of a chamois skin or other drying medium. The principal object of this invention is to combine with an absorbent washing sponge, a relatively straight, flexible edge or corner whereby the sponge may be used for the usual washing purposes and the corner or edge may be used as a water removing squeegee.
Another object of the invention is to combine the squeegee as an integral part of the sponge where it will serve as a resilient stiffening member, hand grip, and reinforcement for the cellular sponge portion.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efiiciency. These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. 1 is a perspective view of the improved combination squeegee and sponge;
Fig. 2 is a cross-section therethrough, taken on the line 22, Fig. 1;
Fig. 3 is a perspective view illustrating a slightly alternate form of the improved squeegee and sponge; and
Fig. 4 is a magnified fragmentary corner section of another form of the improved sponge.
The first form of the invention consists of a relatively flat, rectangular block or sponge formed from foam rubber, cellular Neoprene, or similar synthetic sponge material.
One of the longitudinal corner edges of the sponge 10 is provided with a relatively straight, sharp, flexible corner edge member 11. The corner edge member is triangular in cross-section and may be applied to the sponge 10 in several ways. For instance, it could be molded as a solid portion at the time of molding the sponge to form an integral unit therewith. It could be a separate triangular strip of rubber or similar flexible material cemented or otherwise secured along one corner edge of the sponge 10.
Another method of applying the straight squeegee edge to the sponge in an economical, rapid, and facile man- 2,715,745 Patented Aug. 23, 1955 2 ner is illustrated in Fig. 4 in which the open cells of the sponge are indicated at 15. In this method, one longitudinal corner edge of the sponge 10 is dipped in liquid rubber or latex cement solution, allowing the solution to penetrate into the cells 15 along the corner of the sponge, as indicated at 16 in Fig. 4, so that the dipped corner will present a solid, flexible, resilient structure, whereas the remainder of the sponge will have an open, absorbent, cellular construction. The entrapped compound, indicated at 16, may be cured either by air exposure or heat to form a resilient solid mass.
In use, the window or windshield is sponged oif by using any desired surfaces of the sponge 10. The drying is accomplished by placing the corner edge member 11 against the glass surface and drawing it across, similar to the usual window dryers squeegee.
In Fig. 3 an alternate form of the invention is illustrated, comprising a cellular, absorbent sponge 12, to two longitudinal corner edges of one face of which flexible strips 13 are applied. The strips 13 are formed with outwardly extending, flexible bead portions 14 which serve as drying squeegees similarly to the portion 11 of the previous form.
The two strips 13, with their beads 14, form, in addi tion to squeegees, hand grips for the sponge 12, and also serve as stiffening members for resisting bending of the sponge. It has also been found that if the two corner portions 13 of the sponge 12 are gripped in the hand, it will tend to bow the middle of the front of the sponge outwardly to form a soft, rounded, and efficient washing surface. The strips 13 may be applied to the sponge 12 in any of the manners described above with relation to the strip 11.
While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claim, without departing from the spirit of the invention.
Having thus described the invention, What is claimed and desired secured by Letters Patent is:
A window washing sponge and squeegee comprising: a substantially rectangular sponge block of cellular, resilient material; a squeegee corner edge member of noncellular resilient material extending along and forming one corner edge of said block for the full length thereof, the cross section of said squeegee corner edge member forming substantially a right triangle with its hypotenuse joined to said sponge block and with its sides in the planes of the two adjacent sides of said block.
