The invention relates to mops. lVhile mops with heads of sheet metal and provided with pivoted handles are well known in the art, the usual types of pivotal 'y connections have not proven satisfactory in service. It has been usual to provide mop heads of sheet metal with spaced ears struck up from thebody of the mop head and proj ecting above the same to which ears .the mop handle is pivotally connected, but with such a construction the ears have to take practically all of the clamping strain and they bend inwardly after a short time an-d the pivot becomes loose and cannot be tightened up so that the handle can be set to the desired inclination for working. The present invention has been designed to obviate these difficulties by interposing a portion of the mop head itself as a bridge between the ears, above the pivot point for the handle, whereby a strong clamping pressure can be exerted and maintained between the handle socket and the mop head so that the handle can be readily adjusted and maintained in the desired position and the ears ofthe head are reinforced against strains interposed by the clamping bolt, the preferred construction also having this-bridge portion of the head struck upwardly or arched to provide increased strength at this point and also permit ears of sufficient length'to be formed integrally therewith and project therefrom without extending materially below the head and thus preventing their marring furniture, floors, etc., with which the mop may come in contact.

A further obj ect of the invention is to provide simple and effective means for connecting the mop body to the mop head. The invention further consists in the several features hereinafter set forth and more particularly defined by claims at theconclusion hereof. j

In the drawings Fig. 1 is a plan view of a mop embodying the invention;

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a side elevation view, partly inL section, the section being taken along the line 5o 3 3 of Fig. 1.

The numeral 8 designates the mop head,

formed as a sheet-metal stamping, preferably of triangular shape, -having an upwardly extending, peripheral flange 9 to which the mop body is secured by rivets 10 that pass through 60 the fabric-reinforced portion of saidfmop Thexmop-.head has a centrally `disposed bridge portion 11, 'preferably pressed* `upwardly therefrom, and-ears 12 struck out and 65 pressed downwardly on opposite sides of the`y bridge 11,.the bottom of these ears preferably terminating above the lower flatfpart 13 of the head.`y The mop head may be further reinforced by-pressing the inner body portion The mop handle 15 has socket member 16 f secured thereto in known manner by a screw `17 andk a bolt .18passing through ears 19 form'ed in the separatedpartsof the tubular 75 portion 20 of said Vsocket member, which is"` also provided with spaoed'ears 21, each having a stop. projection 22 engageable with the head to limitthe upward inclination ofthe mop handle relative to the head. l

A pivotvbolt 23 of any suitable construction,v such as a screw-bolt provided with a nut 24, passes through the ears 21 of the socket member and the ears 12 of thehead. v

It will be'jobserved'that the ears 21 of the 85 socket member straddle the bridge portion 11 of the head and the downwardly projecting ears 12 and the pivot bolt 23 is disposed below the bridge, with the result. that the clamping pressure which may be exerted bythe .,90` bolt to keep the handle in its adjusted position is resisted by the bridge and the body of the head and that this bridge, being of arched construction, is well adapted to resist these pressures. Furthermore, the ears arel 95 formed integral with the bridge and body in an arc or segmental-shaped form coextensive lwith the width and depth of the bridge, with the result that the ears are relieved of undue bearing strains and the Vpivot bolt may be U1/,00

'so Y repeatedly tightened up without danger of the ears flexing inwardly and preventing an eiiicient holding of the handle in the desired adjusted position. It is also to be noted that these ears are not formed by merely bending them up in the vform of laps from the head but are formed by drawing portions of the Ahead inwardly as the bridge portion itself is formed. p

The operation of the ymop vis similar to others of this general type, the-pivoting of the handle enabling the mop to be used in places Where the rigid handle mop cannot be readily manipulated and permitting of the setting and maintaining of the handle in the desired angular vposition relative to the head for its efficient use.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention 1s:

1. In amop, the combination of a mophead i of sheet-metal having an arched bridgepor- 1 tion and arched side portions coextensive with the bridge and forming pivot ears, -a handle having an attaching niemberprovided with pivot ears stracldling the ears of said head, and a pivot member passing through `said ears.

2. In a mop, the combination of a mop head of sheet-metal having an upwardly arched bridge portion andarched side .por-

tions coextensive with -th-e bridge and forming pivot ears, the lower edge vof said ears lterminating adjacent the bottom portion of Vsaid head, a' handle having `an attaching v member provided with pivot ears straddling the ears of said head, and a pivot member passing through said ears.

3. In 'a mop, the combination ofa mop head of sheet-metal having a bridge portion with lpivot ears depending therefrom, afhandle having an attaching member provided with pivot ears straddling the bridge and 4vears of sai-d head, Vand a pivot `member passing hthrough -said ears below said bridge.-

In testimony whereof, I IaIiX my signature.

MAX P. J ANISCI-I.
