ARTIFICIAL SPONGE AND DEVICE FOR MANUFACTURING SAME Filed oct. v8, 195o am www! lm/fam Patented Sept. 13, 1932 LEWIS CROWFORD ABRAHAM, OF AUDERG-HEM, BELGIUM ARTIFICIAL SPONGE AND DEVICE FOR MANUFACTURING SAME Appiication aleacetober 8,1930, seriaiNo.
My present invention relates to artificial Sponges for cleaning kitchen utensils vand other similar purposes and it has for its object to provide an improved sponge Vof this type formed of a bag made of gauze and stuffed with any suitable filling material.
In artiicial Sponges of this type the opening of the bag is usually closed by means of a wire inserted through the meshes ot the m gauze and tightened in order to drawthev rims of said opening close together. The ends of said wire section are usually twisted together in order to preventthe mouth of the bag' from being opened accidentally. The
method of making such a closure, as wellV as the closure itself, is objectionablein many respects. i
The making of the closure requires cornparatively much time and skill. The closure itself is objectionable in that it is not very strong andthe twisted ends of the closing wire section may easily hurt the users hands.
My present invention has for its object to provide a sponge of the type described having a fixed closure7 no dangerous unevennesses and a neater appearance than sponges Y closed by means of wire sections.-
Broadly stated my invention consists in providing a cap for closing the mouth of the bag, the rim of said mouth previously drawn close together being housed within said cap. I prefer to secure on the sponge by means of teeth formed on it and engaging the meshes of the sponge but I do not desire to limit my selit1 to this embodiment.
In the accompanying drawing:
Figs. 1 to 3 are diagrammatical views iof diiierent steps of the sponge bag closing op'- eration.
40 Fig-4 shows the finished sponge with its closing cap.
Fig. la shows ac a handle. Y The iirst step of my improved method consists in dra-wing the rims of the opening 1 ofv losing cap provided with 487,352, and inelgium October 14, 1929.
uze 2 close toforming the sponge is cut from a wire gauze tube in thev shape of a sleeve drawn toget her in the shape of a ball and turned inside out to form a bag,
the bottom '3 of which is c means of a wire section or the like.
losed inside by From Figs. 1 and2 it will be seen how the opening neck 5 by means of several radially arranged moving iin'gers 4: whose points 17 engage the f wire gauze near its edge.
In the second step of my provided with a crown of method a cap 6 teeth 7 will-be placed upon the collar `5. The teeth 7 will be bent inwardly to cause the the collar 5 as shown in Fig.
same to engage 8. To this end I use a plunger 8 which in its upward movement will press the cap'6 a gainst 'y the ends of the fingers 4 moved close together, whereby the teeth'7 engaging the on the lingers l will be be curved faces V9 nt inwardly at right angles to the ring of the cap.
In the finished sponge as showny in Fig.
4lthe rounded part of the cap only is visible and forms an ornamentwhich is for instance convenient `for printing a trade mark or any advertisement thereon.
The cap 6 may also be provided with a han-v dle 6a as shown in Fig. 4a, enabling the sponge to be easily grasped. Said handle 6a may be attached to the cap 6 in any desired way.
Having now fully described my said invention, what I claim and desire to secure by Letters Patent, is:
cap closing the' opening in having an annular series of ing intothe edge of the Ycov toward the center of the ca edges of the gauze together.
the cover and prongs projecter and crimped p to secure the ll of said bag may be contracted to form a 2. A scouring device comprising an elastic body, a cover of Wire gauze for the elastic body, the edge of the Wire gauze being drawn together to enclose the elastic body, and a G concavo-conyeX cap closing the opening in the cover and having prongs projecting into the edge of the cover and crimped toward the center of the cap to secure the edge of the gauze together, the cap and crimped w edge of the gauze being roced upwardly into the elastic body, whereby the outer contour of the cap is substantially the same contour as the gauze.
