UNITED MOP HANDLE -SUPPORT f Robert C. Teare, Evanston,

Ill., assignor to O-Cedar Corpn, Chicago, Ill., a corporation of Illinois Application September 21, 1935, Serial No. 41,606

2 Claims.

The invention is illustrated in a preferred em-` bodiment, by the accompanying drawing, in Which- Fig. 1 is a plan view of a mop head equipped with a coupling device embodying my invention; Fig. 2, a side view in elevation, the mop 20 head being sectioned as indicated by line 2 of Fig. l; Fig. 3, a sectional detail View, the section being taken as indicated at line 3 of Fig. 2; and Fig. 4, a broken plan view of the joint formed by the free end portions of the mop head, the View being taken as indicated at line 4 of Fig. 3.

The mop head or frame may be of any suitable construction. The specic form of mop head shown is given merely for the purpose of illustration.

In the specific illustration given, the wire frame I which forms the mop head is provided with free end portions II and I2 which are brought together to form a hinge shank. The extremities of the portions II and I2 are preferably swaged or otherwise enlarged to form an enlarged overlapping joint I3.

The coupling member I4 may be of any suitable construction and material. I prefer to form the coupling I4 of a metal blank. The blank is turned upon itself and then shaped on suitable tools to provide at one end a cylindrical sleeve I5 adapted to receive the hinge shank of the head IIJ and to provide also a rearwardly extending socket portion I6 adapted to receive the handle of a mop. The socket portion I5 may be provided with usual threaded portions I1 adapted to interlockingly engage threads on the end of the mop handle. The upper and lower halves which form the socket I6 are preferably locked together by a thimble I8 which engages the rearmost end of the metal piece I4, the thimble being hollow to permit the handle to extend therethrough.

In order to brace the cylindrical portion I5 and to maintain it in tight frictional contact With the shank of the head, I prefer to form side flanges or webs I9 between the socket portion I6 and the cylindrical bearing I5. At the same time, I provide a longitudinally extending rib 5 20 from the socket portion I6 on one side about the bend of the metal and to the socket portion I6 on the other side. In the illustration given, the rib merges with the socket portion I 6 on each side of the metal. With this construction, 10 the rib and the socket portion provide a continuous vertical reenforcement for the metal piece from end to end. The socket 29, in addition to the advantages mentioned, provides an enlarged chamber a adapted to freely receive l5 the enlarged joint I3 formed by the extremities of the end portions II and I2 of head It. The chamber 209- enables the metal piece M to rock freely on the hinge shank but prevents lateral movement of the free end portions II and I2.

If desired, the rib 2D may be omitted, the ends of the portions II and I2 not being enlarged.

In the preferred practice heretofore, it has been customary to form the metal piece Ili of two parts and to secure them together by bolts and more commonly by a bolt extending through the central portion of the coupling member just ahead of the socket. By forming the metal piece from one part, I am able to dispense with the bolt and to utilize the space formerly occupied by the bolt for forming the vertical rib with its enlargement for receiving the wire extremities.

The new coupling member can be more readily assembled than those heretofore used. After the enlarged ends have been brought together to form the joint I3, the metal piece Ill which has been only partially bent back upon itself, is drawn quickly into position with the cylindrical portion I5 receiving the shank of the head and with the chamber 2Ga receiving the joint I3. The rearmost portions of the metal piece I4 are then brought together and the thimble I8 readily inserted to lock the two parts permanently in the position shown in Figs. 2 and 3. The entire head and coupling device are thus permanently assembled, the free end portions of the head being securely locked within the member I4 while at the same time not hindering the pivotal movement of the coupling device I4.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood ther-efrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

handle coupling formed of one piece bent back upon itself to provide a handle-receiving socket at one end, a transverse bearing at the other end, and a rib extending from the socket and sur rounding the bearing, a flexible Wire frame provided with free end portions substantially axially aligned and each provided with a flattened ter minal together forming an enlarged overlapping joint, said enlarged overlapping joint being received Within said rib and locked thereby Within 10 said coupling.
