This invention rela-testo improvements in brushing and scrubbing implements, partic-` ularlyY mop heads or holders, and -it isthe principal object of this invention to provide a `a mop head with novel and improved means for holding the wire frame of the mop head to its handle sleeve with its meeting ends in intimate contact.

Another object of the'invention is the prolo vision of a mop lhead of simple and inexpen#v sive construction, yet durable andv efficient in operation.

A further obj ect of the invention is the pro vision of a mop head providing a swivel bearing to which the mop handle is secured.V

A still further object of the invention is the provision of novel and improved means for uniting the handle with its holder sleeve. rllhese and other objects and advantages of the invention will become more fully known as the description thereof proceeds and will then be specilicallydefined inthe appended claims. In the accompanying drawing, vforming a material part of this disclosure: Fig. 1 is a plan view ofthe mop and holder constructed according to the 'present invention.

F ig. 2 is a sectional detail front elevation of the mop head holder, illustrating the method of holding the wire frame in the holder.

Fig. 3 is a sectional end elevation thereof. The illustrations in the drawingvrshow a mop head consisting of a wire frame or core 10a which hold the mop 'material 2O and are twisted together in the manner shown, the

lower end ofthe mop yholder 13, the mop holder which joins the wire frame 10 to the mop stick 17l consists of two parts, the stem 13 and the cap 18. The sleeve is made from a single'piece of metal pipe or tubing preferably seamless steel tubing which is formed by special dies into the shape shown. The upper end of tube 13 is provided thereby with the screw thread 16 for holding the mop-stick 17. rlhe lower or front part of the holder is formed by compressing the tube so that opposite portions of its walls form a pair of flat plates joined together along opposite sides. At its lowest end this plate is bent into semimade of a plurality of wire strands 10 and cylindrical shae to form" one half of the bearing 12'for t ie wirey frame lQwhichholds and A'covers' the Welded joint finf'thisframe.

The secondpartof the mop holdercons'ists ofthe cap 18 bent from a Hat strip of metal having preferably double the thickness of Y the wall` of tube 13 to form a complemental part for lthat portion of the mop vholder lying downward of line y14. This capis also bent into semicylindri'cal shapeat 19 to form the second half of t-he tubular bearing 12. The cap 18 is preferablyriveted to the mop hold-v er body 13 by an eyelet rivet15---15a but may be fastened thereto in any other manner `for instance by welding along the edges, or by bolt and nut. Y`

A-very rigid mop holder is produced by terial of the stem is of double thickness, this feature cannot be obtained by mop heads .made of sheet metal.

vIt isralso of special advantage that the tubular part of my inop holder completely encloses the lower end of the mop stick, forming a cap and thereby protects it from mois ture and consequent rotting. l f

Furthermore it is easy to replace a Wornout mop-by removing the eyelet 15 and .replace the same. k

While I have shown-and described the preferred form of my device as an example of the many ways of practically constructing my improved mop head, it is toybe understood that such changes may be made in its general arrangement, and in the construction of the minor details thereof as come within the scope of the invention defined in the'claims, without departure fromthe spirit of the invention and the'principle involved.

Having thus described'myV invention, what I claim as new and desire to secure by Letters Patent is: Y

1. A mop holder consisting of a shor length of normally open-ended seamless metal tubing flattened out for part of its length tovprovide a cylindrical socket to receive a mop'handle and having one of its sides `flattened against the adjacent side toprovide'- -a flat plate closing the end of the socket and having double the thickness of the socket this invention as at all cross sections the mawall, said socket having screw threads for engaging the mop handle, and acompanion plate fastened to said Hat plate, both vof said plates having transverse grooves in juxtaposltion #@eah Qthlgmrlng 'Cylndrwlbew ing for holding aniop frame rotatably supported therein. v

2; A mop holder .consisting :of a short length of normally open-ended seamless tubing attened out for a portion of its-length to provide a flat plate of Adouble the thickness of the tubing, the remaining portion of the tubing beingoylindiieal to receivethe end of th riophandleandhaving'scfeiw threads for enffag ng' the moi handle, the said flat plate end the'oylindrieal portion 'and being positioned.substantiallyy in longitudinal doubleithethiokness ofthe Wall of the tubing fastened to said flat plate, both plates having "grooves therein in juxtaposition to each otherV for holding a inop frame rotatably mounted therein.
