4 Claims. (Cl. 15-114) bing will produce an electric charge on the sponge This invention relates to brushes and more partlcularly to the combination of a sponge and brush for simultaneous cleaning of leather orr cloth surfaces. It is an object of the present invention to provide a cleaning implement which is superior to the ordinary cloth brush because its cleaning action is more thorough.
The present invention is designed primarily for cleaning suede shoes and gloves but may also be used with good success for brushing clothing and as a bath brush, for these latter purposes the shape and size of the brush may be altered somewhat to suit the particular purpose of the brush, 15 but the construction will remain exactly the same.
A further object is to lprovide a device of this kind which is simple in construction and economical in manufacture. l
Other objects and advantages will be apparent from the description to follow, taken in connection with the accompanying drawing in which- Fig.. l is a front view of my improved brush.
Fig. 2 is a vertical section of the brush on the plane of the line 2 2 of Fig. 1.
Fig. 3 is a sectional View on the plane of the line 3-3 of Fig. 2. l
Referring to the drawing I6) represents a block of sponge rubber which is surrounded along its edges by a cylindrical brush I2 having bristles entwisted between wires II forming a frame for 30 block I0. The bare ends of wires I I are arranged close and parallel to each other and extend perpendicularv to the block lil away therefrom and form a tang I3 on the frame II. The tang I3 includes also a third pair of twisted wires I4 3 parallel to the other pairs which extend into the interior of the sponge rubber block at its cen tral plane (see Fig. 2) where they are formed into a spiral I5 forming a reinforcing frame and means to secure the block il! against lateral dis- 40 placement from frame II and brush I2. Tang I3 is preferably accommodated in an axial aperture of a handle I6. To accommodate the spiral frame I5 in the central plane of block Ii! the latter is preferably made of two parts which are 45 joined at the central plane by cementing them to each other after the frame I5 has been inserted between them. The frame l5 is preferably shaped into spiral form so that the resilient, noncorrodible'wire of which it consists may be de- 50 flected transversely to the plane of the spiral and give with the sponge rubber of block Ill, but of course neither th-e form of the reinforcing frame nor the exact shape of the block l are essential features of the device and may be altered to suit 5 special uses of the brush of which there are many. When used for cleaning suede leather articles such as shoes and gloves, the bristles I2 will engage the nap of the leather and the rubfrubber block whereby the loosened line dust particles are attracted thereto and adhere thereon,v
l. In a brush, a prismatic block of sponge rubber or the like, a frame surrounding the edges of said block consisting of a pair of wires, bristles entwisted between said wires forming a cylindrical brush thereon in contact with and covering some of the side surfaces of said block, a tang formed by the bare end portions of said wires extending perpendicular to one side of said block, a handle enclosing said tang and means held within said handle and block for supporting said block in a common plane with the axis of said brush. l
2. In a brush, a block of sponge rubber, a frame consisting of a pair of wir-es surrounding the edges of said block, bristles entwisted between said wires forming a brush thereon covering some of the sidesv of said block leaving the v faces thereof exposed, the end portions of said Wires being bare of bristles and extending perpendicularly away from said block forming a tang thereon and another wire in said tang extending into the body of said sponge rubber forming an elastic reinforcing frame therein.
3. In a brush, a blockof sponge rubber, a pair of wires forming a loop therearound, bristles entwisted between said wires forming a brush surrounding and contacting said block and-having their bare ends forming a tang adapted to attach a handle to said block and another wire forming part of said tang extending into the body of said ,block and forming a spiral reinforcement therein and ar support for said block on said handle.
4. In a brush,` a handle, a wire tang havingv a flat spiral at its outer end and forming an extension of the handle, a block of rubber on and surrounding said extension, said block-having opl WILLIAM HERTZBER/G.
