To all whom it may com-em:

. Be it known that; I, DAVID L. SILVER, a citizen of the United States, residing at Clayton, in the county of Gloucester and mprovements 'in' Mop Heads and Detachable Gonnectio'nsThere' A for, oi which'the following is 'a specification, reference being hadtherein'to the-accompanying drawing.

My nvention relates generally to mop or brus heads, wherein the mop strands or brush bristles are secured between a plurality of twisted vwires, said wires being bent upon reverse turns and having oppo wires 1,v are secured adjacent each other,

"by' means 'of anencircling metallic clampsitel facing ends in substantial contact.

e invention relates specifically to means for clamping said ends rigidl in position and in substantial contact, andto the-production of means adapted for.detachable connectionto an operating handle. One of the objects of .the invention is the provision detachedfrom the ban le tion of pressure at one point only.

i of an element which will' not only provide the necessary. clalnsling1 means," but which also co-operates wi e operating handle whereby it may be automaticall secured to lthe atter by the application 0 pressure on y.

Another object of the invention is the provision of means whereb the head may be by the app ica- Still another object of the invention is I the provision of a] mop or brush handle so constructed and so (Bo-operating with .the head, that either side of the head may be *applied fiat-wise to the work, the handle remaining 'at the same inclination thereto. Other objects will be apparent from the following specifications. s

' In the drawing forming a part of this specification Fi re 1 is a com osite view ,showin the mopcad and the andle separated t erer i a I y Fig.2 is a perspective view,of the receiving end of the handle I \L ig. 3 is afraginentapy view, partly int section, showing t e han le applied to'the mo -head;'

it .isibent to clampm p I v lieferring specifically to the drawings,

the invention is here shown as applied to a mop-head A. As hereinbefore; indicated,

the invention is equally a p'licahle to a brush, or an other kind of ead.

. The mopead A: is herein shown as in eluding a sup'portin 'member 1 comprising a plurality of twisted wires, a plurality .of'strands of fabric being held-between the wires and constituting a tuft which is-of greater widththan thickness, rendering it somewhat fiat on each side.

The opposed meeting ends of the twisted mg member 2, which, by die stamping,' is bent around the wires 1 in close contact therewith, and which may be rigidly sol-' dered or. brazed thereto, whereby-.rotative or lateral movement with respect'to the laid between the flanges,transversely of the clamp, and the flanges 14: and 13 are subjected, to the action of a die which clampsv them tothe position'shown in Fig. 5, the flange 14 extending over the flanges .13, and

this construction part of the metal of the clamp is forced, under high pressure,'1 nto the spirals formed by'the twisted wires, and rotative movement between the clamp and wires, as well as movement of the clamp longitudinally of the wires, is efiectually the blank Y r the Wires being clamped therebetween. "By

substantial y flat front dicated, the stem 3 tapers from its point ofconnection to the clamp 2, and, near'the outer end thereof, is interiorl provided with a dog 5', provided with as ank-6,. en-
