This invention relates to a new and improved mop and more particularly to means for connecting the mop head and mop handle.
In mops as generally used, the handles are secured to the mop head by means ot someV form ot pivoted connection to which the handle isv detachably connected. ln general, such methods ot' connection are either by interlitting screw threads on the two parts or by a clamp carried by the head adapted to lit around the end ot the mop handle. lNith the threaded connection where the thread is simply pressed into the wood or" the handle, the thread quickly becomes worn and the handle is no longer securely 'fastened to the mop. Also, with such threaded connections, the head is easily loosened from the handle when turned in use which makes its use inconvenient. l
"With the clamp term ot connection, there are small parts such as bolts and nuts, the threads ot which wear in use and moreover these small parts are easily lost. Further, the connection or disconnection ot the handle usually requires the use ot' tools and ot handling ot the oily mop head.
It is an object ot the present invention to provide new and improved connection for mop heads and handles adapted to positively secure the two members together and yet to )ermit them to be se )aratednb f va sino'le moven ment when desired.
It is a further object to provide a conneetion of this' character which connection in itself provides pivoting between the mop head and handle.
It is a further object to provide a connection composed ot but .tew parts and adapted tor ready commercial production.
Other and further objects will appear as the description proceeds.
I have illustrated certainpreierred embodiments ot' my invention in the accompanying drawings, in which- Figure 1 is a perspective view of a mop head and the lower port-ion of a handle se# cured to the head by means ot my improved connection;

As shown in Figure 1, the mop head comprises the body 11 which is preferably formed et metal and which is provided with the upturned edo'e 12 to which is secured the mop 13. As best shown in Figures 2 and 3, the body 11 is provided with the oii'lset or raised portion 1-1 and with the struck up arms 15. rllhe reinforcing member 16, pretterably :termed of heavier metal, is located under the central part ot the raised portion la and is provided with the upwardly extending arms 1'? which are located adjacent the arms 15 et the member Y11. y
, rllhe arms 15 and 17 are provided with reg istering perlorations in whichis fitted the pivot rivet 18. The handle 19 is provided at its end with a transverse slot 20 into which are iitted the gripping members 21 and 22. The member 21 is provided with the arms 23 and 1241 which are clamped around the adjacent portion ot the handle 19. 1t will also be oted that these arms encircle the body ot the gripping' member 22 and press it inte engagementI with the handle. rllhe clamping inember 22 is provided with the arms 25 and 26 which are similar to the arms et the member 21 and which clamp the body portion oli the member 21 to the handle end.
The terrulc 27 is clamped around the handle and encloses the clamping members. rlthe lower ends of the clamping members 21 and 22 are provided with the separated grippiifig portions 28 and 29 and with the outt-urned lips 30 and 31. These members are formed et resilient 'material adapted to have a clamping action upon the rivet 18 when iitted upon it.
rllhe body member 11 ot the mop may be termed et' relatively light material since the strain troni the handle connection is transmitted to it largely through the extended surface et the member 16 which is made of stiff material.
The method of clamping the two members 21 and 22' to the handle end eectively holds the mop head.
the two members together so that no splitting lstrain isiput upon the handle end when the handle is forced into connection with the mop head` The -form of construction shown in Figure 8 presents a method of retaining the gripping members in place dii'llering lirom that shown in the other figures. In this form ot construction the gripping members 33 and 3d are placed in the slot in the handle 19 in a manner similar to that shown in the other ligures. rlhe members and have no clamping arms but have registering perorations, and are provided with a gripping portion similar to that ot' the other form of gripping members 21 and 22.
The ferrule is put in place and the rivetv 36 is inserted through registering openings in the tei-rule, handle and gripping member and its end is upset to irmiy retain the parts together.4
1n the application'ot' the handle to the mop head, the lips Z'SOfand 3l are placed in contact with the rivet 18 as shown in lFigure 6 and pressure applied. The lips are separated by the member 18 which slips up between the portions 28 and Q9 as shown in Figure v3. These' portions clamp the rivet suiciently strongly to prevent accidental removal of It may, however, be readily removed when desired simply by holding Vdown the mop head as by means oi? placing a foot upon it and pulling upwardly on the handle.. 1llhis connection in itself provides the necessary pivoting so that the mop head may rest i'iat upon the iioor or wall regardless of the angle at which the handle is inclined. The handle shown in Figure 8 is applied in a similar manner. v
l have shown certain pre'lerred embodiments ol' my invention but l contemplate such further modiications and changes as comer within` the spirit and scope of the appentv ed claims.
