1 Claim. (Cl. 15--244) The present invention relates to a lining for sponges of absorbent resilient material.
It is an object of the present invention to provide a lining for sponges of cellulose, rubber or other resilient material that will prolong the life of a sponge.
Another'object of the present invention is the provision of a lining so constructed that it will allow full flexibility of the sponge.
A still further object of the present invention is the provision of a lining that is water repellant.
A still further object of the present invention is the provision of securing means in the lining.
A still further object of the present invention is the provision of a lining having a portion of its side edges tapering.
A still further object of the present invention is the provision of a lining for sponges having a channel or recess.
Other and further objects of the present invention will appear in the following detailed descriptionwhen studied in conjunction with the accompanying drawings, wherein:
Figure 1 is a plan view of the water repellant lining.
Figure 2 is a side elevational view of a sponge mop equipped with the lining.
Figure 3 is a sectional view through the mop showing the head in full and illustrating the lining positioned in the recess or pocket of the mop.
Figure 4 is a sectional view taken on line 4-4 of Figure 2, the mop head and handle being omitted.
In the drawing the numeral represents the lining and it comprises a strip of water repellant material 11, having straight sides 12 and tapering sides 13, and adjacent each end of said strip there is provided holes 14. The tapered side edges allow for variations in the pockets of different sponges so there will be no binding or wrinkling of the lining when placed in the mop and cemented thereto. The inner side walls of the sponge will always contact the entire tapered end portions of the fabric thus avoiding any wrinkling or pinching of said fabric.
2,694,213 Patented Nov. 16, 1954 The lining 10 is cemented into a pocket or recess 15 of a sponge 16, the holes or apertures 14 being in transverse alignment with apertures 17 in the sponge 16, the apertures 14 and 17 receiving eyelets 18 that secure the lining to the sponge at the open end of the sponge.
The inner face 19 of the lining engages the T-shaped rubber head 20 and handle 21, thus protecting the side Walls of the sponge in the pocket 15.
In carrying out the present invention, the outside face of the lining is covered with an adhesive, the 1in ing placed in the pocket 15 of a resilient sponge, the outside face pressed against the side walls of the pocket 15 until adhered thereto, the apertures 14 and 17' being aligned and an eyelet 18 securing the sponge and lining together. The pocket 15 now being lined is ready to receive a resilient mop head 20 that is inserted into the pocket. The sponge 16 is aflixed to the mop head by passing a cord or lace 22 through the eyelets and tied.
While the present invention has been disclosed in connection with certain specific embodiments thereof, it is to be understood that these are by way of example rather by way of limitations, and that the invention is to be defined by the attendant claim which should be given a scope as broad as is consistent with the prior art.
What is claimed is:
In combination, a sponge having a pocket, a lining for said pocket, and a T-shaped head for insertion in said pocket, said pocket being open at one end and having inner walls, said lining comprising a strip of water repellant material tapering along its edges adjacent each end, said strip adjacent each end provided with apertures that receive eyelets for securing the ends of said strip to corresponding apertures in the walls of the sponge pocket at its open end, intermediate portions of said strip being attached to the inner walls of said sponge pocket and enclosing said head, whereby securing means through said apertures and eyelets will unite said sponge, lining and head.
