VAfurther objectof the .invention is the provision of a device o f'this character having a flexible abrasive portion adaptedy toV enter constricted spaces in a surface to be cleaned, thereby increasing the efficiency of the scrub-A ber.

As the tubular braid is passed over the former 4L the threads 2 are separated from each other and in practice suchthreads are twisted or tilted .slightly from their original` positionso that the edges 3 thereof are eX- 50 posed. to form, as t were, cutting edges for abrading or cleaning. metal, glass or other surfaces. y

In the formation of the scrubber a section 6.

may be sleeved over a hollow tube 5, as shown in F ig. V2. portion of the tubular wire `mesh fabric sleeved over the tube 5 in Fig. 2

is shown as ylying iiatly against the outer sur. face of the tube'as indicated at 7, while a.k

surface corrugation -in the tubular fabric. The *sleeve` 6 is compressed longitudinally throughout its entire length while inposition upon the tube 5, the portion? being shown lying flatly upon the surfacey of the tubeto illustrate the position of the fabric when first sleeved upon the tube and before it is com-Y pressed longitudinally as above described. lo

This longitudinal compression of the sleeve section 6 not only forms external corrugations therein thus increasing the body orl cross sectional bulk of the sleeve but also tends to increase the diameter of the braided tubular section. Y

A core 9 formed wholly or partially of a suitable abrasive material such as Woven, braided, knitted or Vlinked metal mesh Work, or of abrasive metal threads or strands such as those which are U.produced as waste in turning or planing metal parts, is inserted within one end ofthe tube 5 where it isavailable for withdrawal Withthe compressed metal sleeve 8 in such amanner as to lie within the sleeve after the withdrawal of the parts from the tube 5. ln the present instance the core 9 is shown as made from a section of tubular wire mesh fabric similar vto that which is sleeved over the tube 5. rlhe core` 9 being preferably com-` ressed vlonitudinall and curvedV transversely to make it more compact. lt will, of

course, be understood that any desired num- 'l ber of sections of wire mesh fabric Vmay be employed in lieu of the single layer illustrated in the drawings.

A Wire l0, of lessA length than the Vcore 9V may be inserted within the tube 5 adjacent to the core for a purpose which will be more fully described hereinafter. i

Upon removal of the sleeve 6, core 9 and wire l() from the tube 5 these parts assume a position substantially as shown in dotted lines in Fig. 8 with the core 9 and wire l0 lying within the sleeve 6 which is compressed longitudinally of the core to form surfacev corrugations 1l therein. The core 9 and sleeve 6 zare Vboth compressed longitudinally to permit the ends of the Wire l0 to be brought together and secured as shown at l2. The ends 13 of the core 9 are then brought together and secured to each other in any suitable manner as by stitching or linking with a wire or cord as indicated at 14. The free ends .of the sleeve 6 are then brought together and securedrto each other by stitching or in any other suitable manner. In this way the wire 10 tends to retain the core 9 and sleeve 6 in their compressed state and prevents undue eX- constricted portions ofthe surfaces to be scrubbedor to conform readily with irregular surfaces which it may be desired to clean.

'cleaned The wire `l() has the ends thereof connected together at such a point as to hold the core and isleevelagainst undue expansion while permitting sufficient expansion or movement of the core and sleeve relative to the wire as vto enable the parts of the core and sleeve to moveto a limited extent and flex sufi'iciently for efficient operation. j

Thus, among others, the several objects of the invention are achieved. lt will be understood, however, thatnumerous changes inV construction and rearrangement ofthe parts' might be resorted to without inlthe slightesi Vdeparting from the spirit of the inventionr as Vdefined in the claims. Y l

Vilhat l claim is: n

l. A scrubber comprising an annular body, a c-oreformed of abrasive material, said core being disposed over said body, and a separate tubular wire mesh disposed over the core,

' said mesh being of a length greater than the core'and being completely sleeved thereon whereby to form surface corrugations in said mesh. Y Y

2. A scrubber comprising a core of reticulated tubular wire mesh fabric, and the length of said covering being greater than that of the core and the former being conipeltely sleeved upon the latter whereby surface corrugations are formed in said covering. 3. A scouring device comprising an abrasive flexible ring-shaped hollow covering disposed in the form of an axially hollow truncated cone having an outer vedge portion, and

a core within said coveringl and spaced from the outer edge of said cone.
