Figure 8 'is a fragmentary plan view illu'str'ati'ng the manner in which the coupling link of the control means is connectedwith the valve stem of the, device.

Referring to the drawings in detail, and wherein similar reference charactersdes'ig nate corresponding parts throughout the several views, the 'letterA designates the handle portion of the device, B valve means carried by the lower end of the handle A, G means for controlling the valve'BfD .a soap distributing cup or cap, and E a mop proper or head'retainedin' position by means ofthecup or'cap D.

Referring now to' thehandle portion A, and which is prefe1ably :forn1 'e cl of metal, the same isfof hollowdormationnudism bodies a grip 1O tapering jatits' lower end into a tubular shankll, The lower end of the tubular shankjll'is fiaredioutwardly for.

providing an annular shoulder 1 2provid'ed with a depending ring. flange 13; lfhe'jupQ per end ofv the grip 10 is threaded for re- I movably receiving a threadedfcl os ur'e cap 14c, and which cap may be provided with a suitable ring 15 whereby theinop ay be hung up while not being used, I

This closure cap 145 when removed from the grip 10 provides an opening wher eby the hollow handle may-be readily filled with a suitable liquid soap. The valve means B, and

whichis disposed at the lower end ofthetlubu lar shank 11,

embodies a tubular valve chamher 16 dape ed to fit snugly within'the ring flange 13 and be secured thereto in any suitable manner such as by welding, soldering or "the like.

This valve chamber 16 and which extends coaxially of the tubular shank 11, is "closed at its lowe f. nd by a isc' PliQY cle Y i an axiallydisposed opening'18, aid which disc provides aseatjtoi the valvehead" reciprooably mounted the cha ber' 16. Connected to the upper side for the head 19, is a valve stem 20 which is adapted forsli'ds eme in uitab e alv stem d 21 carried by the chamber 16;

ried by the valve stem 20 between the 21' 'tbl 2 f-- guloes is a su1 a e stop 1.1 01 receivin one end of an expansion coil spring 23, the

opposite end of which springacts against the uppermost guide 21. This expansion spring 23 normally retains the head 19 in closing relation over the aperture 18 provided in the valve seat 17.

I Formed inn' ardly of one side oi? the handle portion A, is a longitudinally extending channel 24 having its upper end extending for a slight distance into the lower portion of the grip 10, and having its lower end terminating just above the flared lower end 01'? the tubular shank 11. Mounted at the lower end of the inwardly pressed channel 2% and as by soldering, welding or the like, is a guide bearing 25 provided with a guideway 26 opening inwardly off the lower end of the tubular shank '11. By extending the channel 2% upwardly into the lower end of the grip 10, and as will readily be observed in Figures 1, 2 and 8,. a relatively deep pocket 24. is provided at the upper end of the channel.

Referring now to the control means C tor operation of the valve B, the same embodies an operating lever 27 in the liorm of a bell crank lever and embodying a relatively short pull arm 28 and a longer arm 29 having a thumb piece 30 provided at its free end. This lever 27 is pivotally mounted at the juncture of the arms 28 and 29- within the pocket 2 1 with the arm 28 extending inwardly toward the axis of the handle portion A, and with the arm 29 extending toward the tubular shank portion 11 with the I thumb piece 30normally disposed outwardly past the external peripheral surface of the handle portion A. Pivotally connected at its" upper end "to the inner end. 01"" the pull arm 28,.is a lift rod 31 which extends longitudinally within thechannel 24s, and which rod has an enlargement formed at its lower end provided with a threaded bore 33.

Reciprocably mounted in the guide hearing 25, is an L shaped coupling link 34, one arm of which projects upwardly past the guide bearing 25 and is threaded at its upper end for threaded engagen'ient in the bore 38 of the-lift rod 31. The opposite arm ol the L-shapcd coupling link 34 is provided at its end with a split coupling 35 which is adapted to be clamped about the spherical head 36 formed at the upper end 01 the valve stem 20.

Disposed about the upwardly projecting end of the coupling link 34c and between the guide bearing 25 and enlarged lower end 32 of the lift rod 31, is an expansible packing 37 which serves for sealing the guideway 26 thru which the arm of the coupling means reciprocates. As will be observed in Figure 41-, when the control means C is in its non mal position and the valve head 19 in s a ing relation upon the valve seat 1'7,

packing 87 is compressed for effectively preventing escape of the liquid soap thru the guideway 26. In Figures 3 and 5, and when the control means is depressed for opening the valve head 1.9, the expansible packing 37 still serves for efiectively closing the guideway 26;

The soap distributing cup or cap D, and which is intended for distributing the liquid soap to the mop head E, is of substantially bell shaped formation, being closed at its lower end and provided at its upper side with a threaded flange 38 for threaded engagement with the lower end of the tubular valve chamber 16. The bottom wall of the cup D is bulged upwardly at its axial center as at 39, and which bottom formation of the cup tends to deflect the soap toward the side walls of the cup whereby the soap is directed thru suitable rows of apertures 40 against the mop head E. These apertures 40 are provided in the side walls of the cup for insuring distributing of the liquid soap to the mop head. By observing Figure 4, it will be seen that the ring flange 38 extends inwardly from the upper wall of the distributing cup, and provides an annular shoulder 41 which encircles the valve chamber 16 and is dis posed in confronting relation with the shoulder 12 of the tubular shank 11. v

The mop proper or head E and which may be formed 01- any suitable material, is preferably of tubular formation and bound at its upper-end by means of suitable binding strings 42. In securing the mop head in position, the distributing cup or cap D is first removed from the valve chamber 16, after which the mop head may be readily slipped over the valve chamber 'into'abutting relation with the shoulder 12. The cup I) may then be threaded upon the lower end of the valve chamber for retaining the mop head against withdrawal oil ofthe valve chamber, and in which position it will be seen that the material of the mop head engages the cylindrical'side walls of the distributing cup.

[he 7 longitudinally extending corrugations 4-5 for permitting of a firm grip being obtained upon the handle portion during use of the mop.

In use, and when it is desirable to soap the mop head E, the operator merely places his thumb or any linger upon the thumb piece 31) and presses the same inwardly whereupon the valve head 19 will be raised from the seat 17 and allow a suitable quantity of the liquid soap retained in the hollow handle A to flow into the distributing cup'or cap D and hence thru the apertures 40 upon the material of the mop head. Upon releasing pressure on the thumb piece 30, the expansion spring 28 will readily move the valve head 19 to a closed position and the thumb piece grip 10 is preferably provided with Cir ageargem Y a outwardly of the pocket 2% into a position for subsequent operations. i

- It will be seen that thechannel 24 and pocket" 24" provide means whereby the control means may be mounted in a protected and out ot'the way position. The manner of attachment of the mop head to the lower endof the handle portion A, also serves as a protecting means torthe'valve B during use of the mop. r
