The improved characteristics of the sponges of this invention are attained by providing novel tufts within the framework of the sponge, and so located at or near the working surface in order that the working tips of each tuft operate as effective brush working ends.
Prior to this invention, synthetic sponges having brush tufts therein to improve their utility, although known, were not practical for many reasons. The insufficiencies of prior articles stem from the lack of a satisfactory method for constructing tufted synthetic sponges. The most common tufting method, the staple-set method, is unacceptable for setting synthetic fiber tufts in foam or synthetic sponge substrate. Synthetic sponges do not possess the mechanical ability to hold an anchor or staple during prolonged used. Therefore, U-shaped tufts normally employed in brush making cannot be durably attached in flexible or cellular substrates.
It will be apparent in the discussion which follows wherein the novel spongelike products of the invention differ from prior sponges and it should be apparent why the improved tufted sponge offers superior cleaningqualities among other advantages.
Objects and advantages of this invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the steps, methods, combinationsaand improvements pointed out in the appended claims.
.This invention consists in the novel steps, combinations, and improvements herein shown and described.
The objects of this invention will now be described. While the invention is primarily concerned with new and novel sponge-type-cleaning tools, it should be realized that the principles of this invention are attained only through 'the novel method f picking and forming synthetic filament tufts, and these principles are applicable to situations wherein: (I) multiple filament single tufts are formed, (2) multiple tufts of multiple filaments are formed, (3) complete tufted arrangements are formed, and (4) continuous modular tufted arrangements and components are formed.
It is therefore an object of this invention to providenew and useful tufted sponge cleaning tools. Another object of this invention is to provide a tufted sponge having improved cleaning qualities by having placed near or at the working surface synthetic filament tufts.
Yet another object of this invention is to provide a brushing tool having the ability to retain liquid cleaners during usage. Still another object of this invention is to provide novel brush constructions employing the tufted sponge units having the qualities heretofore mentioned in the foregoing objects.

' illustrating the tuft arrangement.
In order to describe the invention more fully, reference is now made to specific embodiments illustrated in the drawings. The invention is directed to brush making wherein tufted sponges are formed employing tuft-picking devices, filling the said tuft-picking devices with synthetic filament, heating the nonworking end of said tuft and inserting same into a sponge substrate, allowing the heated end to fuse as it cools, to the sponge, and upon removal of the picking device, leaving the tuft attached to the substrate.
When the prefused end of the tuft is inserted into an aperture on the scrubbing or working surface of the sponge substrate, the prefused end conforms to the internal confines at the base of the aperture. The heat-softened filamentary material then enters the porous surface at the base of the aperture. When the prefused end of the tuft cools, the mass of material conforms and adheres to the internal confines at the base of the aperture to hold the tuft in the sponge.
In FIG. 1, a sponge substrate 102 is shown containing tufts of synthetic filament having different trim lengths. Filament tufts 100, and 100", designated as X, Y, and 2 respectively, are attached to the substrate and their nonworking end 101, 101' and 101". The filament portion of tuft X is completely free of substrate 102 excepting at the point of joining 101. The fused portion of filament actually is hardened to and attached to the sections of substrate 102 in such a manner as to allow a bond between the sponge and the tuft. For purposes of explanation, the sponge section 102 of FIG. I is in the wet state, and shows different tuft arrangements. The tuft X protrudes beyond the surface of sponge 102, and would act more like a conventional tuft in a tufted brush during usage. The tuft Y is trimmed in such a manner that when the sponge is wet, the working tip of the filament tuft is level with the surface of the sponge. The tuft Z is trimmed in such a manner that the working tip of the filament tuft 100" never extends to or beyond the surface of the sponge 102. However, when the wet sponge is compressed in direction A as shown in FIG. 2, tufts 103 are exposed. Tufts 103 are held firmly in the sponge substrate 105 by the heat fused portion 104.
The sponge 107 of FIG. 3 demonstrates how the tufts can be effective in cleaning. Tufts 106 are deflected in various directions, as shown, when pressure from hand 109 pushes down and forward along direction B and C, thus exposing the working tips of filament tufts 106. In turn, the tips are in contact with the surface 108, and subsequently, work similar to brush tufts in removing unwanted material. The sponge portion 107 retains solvent and chemicals when needed.
While the invention is susceptible of embodiment in many different forms, there is shown now in FIGS. 4, 5 and 6 specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principle of the invention and is not intended in any way to limit the invention to the embodiments illustrated.
Particular attention is now given to FIG. 4 wherein there is shown the tuft-picking device 112 containing filament 110 fused and still in the semimelt state 111, said tuft-picking device held in support 113. Prior to the picking device indexing in direction D, a punched hole with bottom 1 14 in sponge is provided for. The hole is formed by inserting a probe through the cell structure of the sponge, thus tearing and widening an opening. The fused end portion 111 is then indexed in direction D allowing the fused portion to fuse and cool around the sponge substrate as shown in FIG. 5. When the tuft-picking device is indexed in direction E as shown in FIG. 5, there results a pretrimmed synthetic filament tuft I10 securely fastened to the sponge 115 as shown in FIG. 6. This type of construction is not possible by employing conventional methods for stapling filament tufts.
FIGS. 7-1 I show how segments with synthetic filament tufts may be assembled into a finished sponge mop. More particularly, as shown in FIG. 7, the segment 200 is comprised of tufted sponge. An end view of this segment is shown in FIG. 8. In FIG. 9 two similar segments, 200 and 200' are placed next to an untufted section of sponge 201 and are so aligned that by providing a cap 202, as shown in FIG. 10, there results a tufted sponge mop having handle 203. The finished mop of FIG. 11 is comprised of handle 203, cap section 202, and tufted sponge section 204.
Many types of cleaning tools can be manufactured employing this tufted sponge concept, that heretofore were not possible. For instance, the tufted sponge rug cleaner shown in FIGS. 12 and 13 is constructed in such a manner that allows one to hold on to aerosol cap 208 while cleaning. The sponge section 206 containing tufts 205 is attached by means of an adhesive 207 to the cap.
The preferred sponge compositions for making the tufted articles of this invention are cellulose, polyurethane and foamed polyolefins. The tufts of this invention can be composed of any thennoplastic composition such as polyamides, polyolefins, polyvinyl chloride and the like. Colorants, extenders, plasticizers and modifiers may be added to these materials as practice dictates.
The cell structure is not limited in any way, and can be fine or coarse. Also, orientation of the sponge structure can be varied, and is not limiting. The magnitude of the filaments described in the invention is in the range of 0.006 to 0.200 inch.
The tufted sponge construction of this invention can be employed to prepare improved products such as: mops, polishing brushes, abrasive strip brushes, rotary brushes, liquid-retention brushes, auto cleaning sponges, kitchen sponges, and the like.
The foregoing considerations conclusively demonstrate the advantages to be gained by providing tufted sponge constructions hereinbefore described. When such constructions are incorporated into brushing tools, there is attained new and novel products heretofore not known.
