BATH-SPONGE DEVICE.

Application fled May 1?, 924. sh m Io. 714,088.

- a simple, efficient, durable sponge device in any rial and a reenforcin which the sponge can be very. readily attached to or detached from the handle portion'. I Another object concerns the provision of means whereby the sponges can be made and sold on the market as replaceable units for given handle unit.

A -Further object concerns the provision of means whereby the sponges are adapted to be firmly and securely connected to the handle portion so that in use. this connection will not become defective.

The invention is illustrated in the accompanying drawings, of which Figure 1 is a side elevation of the device; Fig. 2 is a plan view with a portion broken away; 1 Fig. 3 is a section taken on the line 3-3 of F 2; and

Fig. 4 is a section of Fig. 2. I

The form of the invention shown in the drawings is a preferred form, although it is understood. that modifications in the construction'and arrangement of the partsand in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims. y

I In its general aspects the invention comprises the provisioii of a sponge, preferably a rubber sponge, the upper portion of which is treated with suitable cemeutitious mateg ediiu'n for the purpose of strengtheningii t The reenforced strengthened portion is? engaged by; metallic plates at the top and sides therof;; The metallic plates form a frame .whic li is adapted to engage with the handle,prefertaken on the line 4l ably in a readily adjustable manner so that the handle can be quickly applied to and removed from the body portion'of the sponge unit. In the preferred which is shown in the drawings, there is shown a sponge 1, preferably of rubber, the

form of the invention,

upper portion of which is impregnated in ny suitable manner with a. semirigid cementltlo s material 2 in which a wire mesh or fabric 3 is suitably embedded.

As shown in Fig. 4, the top of thereon forced standard is' provided with a metallic plate 4, and the sides are embraced by a ring 5 having a groove 6 therein in which the edges of the Wire3 engage and which extends slightly beyond the cementitious ma:- terial. The upper ends of this ring 5 are scalloped and turned over, as at 6, ,to hold the plate {in position.

The plate 4 is provided at opposite sides with upturned teeth 7 and 8 which are adapted to extend through apertures in a plate 9 formed on the bottom of a handlev portion 10. These teeth extend into notches formed in the handle portion and when engaged in position prevent the handle portion from turning with respect to the sponge. This plate 9 on the handle portion, as shown in Figs. 2 and 3, is turned down at its opposite end in the form of flanges 11 and 12 provided with a rib '13 adapted to engage with-the rib 6 on the sponge. The flange portions 12 and 13 are preferably of spring material sothey can he slipped over the upper edges of the sponge unit. The teeth 7 and 8 engage in the notches in the handle and prevent the sponge from moving relatively to. the'handle. \Vhen the sponge becomes worn'or needs to be taken out to be dried, the handle plate can be slipped off the sponge unit, which can be laid aside for cleaning or for drying or for replacement when the sponge is worn out.

It is thus seen that I have provided a simple. strong, durable sponge unit and a simple. and readily applied handle unit which can be easily attached together to enable the sponge to be used With the handle.

1. A bath sponge device, Which includes a sponge, a layer of rubber formed on the upper portion of said sponge, a wire mesh embedded in the rubber layer, the ends of the Wire extending beyond the rubber material, a plate covering the top of the sponge, and a flanged ring embracing the sides of the upper portion of the sponge, said ring *having a groove therein in which the ends of the wire engage, the flange of the ring holding the plate on top of thesponge. 2. A bath sponge device, which comprises a sponge "a metallic frame attached to the upper portion of the sponge and having.

teeth extending upwardly therefrom, a handle a flanged metallic late on an end of said handle the flange portion being adapted to spring over the edge of the frame on the sponge, said handle having notches therein into which said teeth are ada ted to project to maintain the sponge in a efinite position with respect to the andle portion.

3'. A bath sponge device, which includes a sponge, a layer of rubber formed on the up er ortion of said sponge, a wire mesh em ed ed in said layer. of rubber, the ends of the wire extending beyond the rubber material, a plate covering the top of the sponge, a flanged ring embracing the sides of the upper portion of the sponge, said ring having a groove therein in which the ends of;;the wire engage, the flange of the ring holding the plate on top of the sponge, said plate having teeth projecting upwardly therefrom, a handle, a plate on an end of said handle, said handle having notches therein, and sprin flanges dependent from said plate on the iandle, said flanges having grooves to engage wlth the ribs on the metal frame of the sponge whereby the plate on the handle can spring over the metal frame on the upper 'portion of the sponge. t
