UNIVERSAL Mor Application led March 19, 1928. Serial lim-262,778.

assume through the combined movements by a single clamping means:

It is a further object of the invention to provide a mop which has two dusting elements of which each may be' used independently of the other or simultaneously with each other. With these and other objects in view 2Ol `the invention yconsists in certain novel combinations and arrangements of parts hereinl after more clearly described and finally pointed out in the appended claims and illustrated in the accompanying ldrawings in which:

Fig. 1 is a front elevation of 4my universal mop, parts of cap 40 and sleeve 30 are broken away to show theinterior construction.

Fig. 2 is a sectionalelevation on line 2 2 of Fig. 1.

double mop head consistingofa plurality of wire strands l() which ared twisted about each other and hold mop material 11 between them. The wireslO'are bare of mop material in their middle part lOwhich is covered by an I shaped tubular sleeve 30. Those parts 0f wires l0 which protrude from either side' of sleeve 30 have each'the form of a com-l points and to avoid deformation of the ring shaped dusters closing the aforementioned S so that the mops have the shape of a'dumb- The' illustrations in 'the vdrawing show a` bell. The sleeve 30 between these mop heads is journalled in two bearingor clamping-l plates which enclose thefcylindrical part `of sleeve' 30, with their semicylindrical parts 40, vwhile their flat portions 41 lie flat against a plate 51 whichl forms a part of the tubular mop holder 50. The plates Il are held on laminated plate 51 by means of screw 52 and wing nut 53 about' the axis of which they may oscillate so-that their journal por-- tions with sleeve 30 and rings 100 and 101 can be oscillated to assume extreme positions :c or y indicated by dotted lines in Fig. 1

and any other position Ibetween these extremes. The two clamping plates 4:1 permit the rotation of the mop in their bearing pcr-` tion 40 and the clamping .of the mo in any position in which it may be place Plate 5l is integral with mop holder socket 54, both are made from a piece of commercial brass or steel tubing which has threads 5,5l im ressed thereon to hold a mop stick 56. T e forward end of this pieceof tubing is compressed so that the walls of the tube lie flat against each other and form' thereby the laminated plate 51 on whichk the clamping plates 41`are held by screw 52 and nut 53.

In operation this universal mop permits of many applications for which other mops cannot -be used as each\one of the two looped portions can be placed in front of the mop stick and used singly. Narrow spaces otherwise inaccessible can be cleaned in this manner, railings, the edges of boards and narrw ledges can be cleaned simultaneously on both sides by placing the two loops on opposite sides thereof. Eachmop can be used separate-until dirty or worn and then the second mop may take its' place. In any p09' sition into which either mop or ring may be placed it can be rotated completely in bearing 40 describing a sphere thereby which is of small diameter. and particularlyuseful for cleaning corners formed by two walls and ceiling for instance.v n

While I have shown and described the preferred form of my universal mop it is to be understood that such changes may be madey rings as comewithn the scope of the inven'? tion defined in the claims without departure Patent is:

Aso a mop holder having a tubular ortrifp .1. A mop comprising a pair of mop rings consisting of wires twisted about each other and a journal portion joining said rings,' mopf material held between the twisted wires' of said'rings, a bearing mounting said journal portion an said rings for rotation, a holder adapted for attachment to a mop stick and apivot arrangedtransversely'to said journal portion joining said bearing to said holder.

2.' A m'op structure consisting of two loop shaped mops arranged in a common plane, said mops being joined to each other by a middle part spacing said 'mbps from each other, a bearing mounting said middle part and said mops for' rotation therein, a mop holder adapted for attachment` to a mop stick j said holder hinge plateshaving channels or holding said sleeve j rotatably between them, a holder adapted for attachment toda mo dy to said bearing plates,

andmeans onv saidpivot for clamping said bearing'plates against. said sleeve.

i j mo loops rotatab a transverse um ring rotation and a 4. A mop structure, consisting of wires twisted about each .other and forming-two separate loops joined by a straight portion between said loops, mo material, on said loops held by the twist o said wires, a tubuj lar sleeve surrounding said straight'portion Y joining the free ends of said wires transversey to said straight portion for closing said loops and ormin means for attaching said y to a mop holder between sai loops. Y 5. In a mop structure of the kind described,

adapted for attachment tc a mop stic a ate portion on'said holder, a pair of bea g plates4 lying againstthe' sides of said plate portion, oove being formedin each late orming together a cylindricalx adapted to hold a'mop 'ramefor pivot bolt v(joining, saidbearing` plates oscillata ly to sai plate portion, and

means on said bolt for clamping said bearing plates ixedly to said frame and said plate portion.'

. 6. In a mop structure the combination with a looped mop frame holding mop material, of a straight middle part on said frame, a

ige-5,278

bearing holding said middle part for rotation therein, a holder adapted :E or attachment to a mop handle and a pivot joining saidholder to said bearing providing said frame about an' axls said middle part. V

7. In a mop structure in combination a frame supporting mop material, a holder providing means for attachment of said frame to a mop handle, vsaid holder having a liat portion, a pair of clamping plates lying against the sides ofvsaid i'lat portion and having complementary grooves forming a journal bearing, at pivot bolt joining said plates to said 'at portion, said mo frame eing interposed between said c amping plates in sald grooves and. means on said pivot bolt for clamping saidfplates to said holder in a; plurality of angular positions withthe axis of theanop handle.
