MOP-HEAD.

Application :tiled May 27, 1916. Serial No. 100,367.

To all whom t 'may concern Be it known that l, CHARLES V. ANDER- soN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mop- Heads; and 1 do hereby declare the following to be a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in mop heads and handle connections therefor.

The improved handle connection is of the general type disclosed in my prior Patent No. 1,009,883, granted to me November 28, 1911. As shown in said patent, a clamping plateor disk is mounted on the top of a scrubbing brush and spaced adjacent the periphery of said disk is a series of holes or perfor-ations. Mounted on the brush handle is a clamping plate or disk which copen ates in clampingb relation with the disk mounted on the rush. For this purpose, the disk on the handle is provided with a pin or series of pins, preferably three, which pins are adapted to fitin the selected perforations of the disk on the brush when the two disks are assembled in clamping relation and in conjunction with the perforations in the disk on the brush determine the angular position which the handle assumes with respect to the brush. A yoke pivotally mounted on the handle, is slipped over the assembled disks to lock them securely against lateral movement. Also mounted on the disk on the handle is a central pin which fits into a bearing member on the disk on the brush and enables the positioning pins to be guided into the desired holes or perforations in the brush disk.

The arrangement briefly described above permits an angular adjustment of the handle on a brush, mop, or the like, in any one of a plurality of fixed positions, and also pro vides a means whereby the handle may be readily detached from the brush and applied to other uses. A striking advantage of the arrangement lies in the fact that any number of domestic articles having similar uses may be provided with perforated clamping members or disks and a single adjustable handle will serve for all of them.

lin practice it has been found desirable that, under Certain conditions, the brush or mop at the end of the handle be permitted to slip or turn on the handle without impairing or destroying the security of the fastening between the two connected parts. For instance, when a brush is being used to clean a floor under heavy furniture, such as beds and the like, it is necessary to lower the handle in order that the brush may be pushed under the bed. The present invention, in addition to generally improving the construction of a handle connection of the above-mentioned type, comprehends means for permitting the clamped brush or mop to slip on the handle and allow the handle to be lowered from its normally high position of adjustment without making it necessary for the handle to be detachel from the brush or mop and readjusted in a lower position. At the same time provision is made whereby the handle may be also clamped to the brush or mop in a plurality of iXed positions.

A further object of the, invention is the provision of an improved mop head. ln the present instance, the mop head is particularly adapted for use in conjunction with mops of the type having a substantially continuous bead, and the clamping parts are so arranged that when a mop is secured to the head, a portion of the mop assumes a pointed shape. A mop of this shape is much more readily pushed into corners and other places ordinarily inaccessible.

A full understanding of the invention will be attained from the ensuing detailed description when taken in connection with the accompanying drawings, which illustrate a structural embodiment of the invention in a preferred form, and the novel features of the invention will be particularly pointed out and specified in the appended claims.

1n the drawings-Figure 1 is a plan view of a preferred form of mop, mop head and handle clamped thereon. Fig. 2 is a vertical section of the same, the clamping plates or disks and handle being shown in elevation. Fig. 3 is a detail side elevation of the handle connection, the parts being shown in posi-- tion to permit the lowering and raising of the handle without detaching the parts. Fig. l is a transverse vertical section of the clamping disks and the yoke for clamping the assembled disks against lateral movcment. Fig. 5 is an isometric projection of Like letters of reference indicate similar parts throughout the several views.

For convenience in description, the handle connection is shown applied to my improved mop head, which will first be described. The mop head of the form shown in the drawings consists of the main mop supporting member or segment A and the adjustable mop clamp carried by said segment.-

As shown in Fig. 2 the arcuate mop-engaging edge of segment A is provided with a groove or channel a which receives a portion of the bead or binding edge b of a hollow mop B. The lateral or transverse edge of segment A is formed with a neck A from which the clamp is extensible substantially in the plane of segment A. For this purpose, segment A is bored longitudinally, as at c all the way through the neck A. Seated in bore a is a screw threaded rod or shank C having at its outer end a head or mop engaging member C. The head C is preferably provided with a curved recess c for engagement with the bead or binding edge b of the mop B. Engaging the threads of shank C and interposed between head C and segment A is a winged nut C2 which bears against the vertical face of neck A. To prevent marring or destruction of the neck A by nut C2 an apertured reinforcing plate a2 is provided.

From the foregoing description it will be evident that turning nut C2 in one direction forces 'shank C outwardly and head C is thereby brought into clamping engagement with the bead b of the mop. By turning nut C2 in the opposite direction shank C can bel made to retreat within bore a thereby disengaging head C from the bead o of the mop and permitting the mop B to be removed from the head.

It will be noted that a. head of the type illustrated in the drawings imparts a somewhat pointed shape to the front portion of the mop with the mop bead converging on opposite sides from the terminals of the arcuate mop -engaging .periphery of segl' ment A. This 1s especially advantageous since the pointed end of the mop may be more readily pushed into corners and other places which are ordinarily inaccessible.

n Fig. 6 is shown a preferred arrangement of clip for securing the adjacent ends of the mop bead or binding edge b. One end of the mop bead is provided with an eye D which is secured, preferably by stitching, to the bead, and the other end is provided with a hook D also secured by stitching to the bead. The t Wo ends may be readily secured together by inserting hook D into eye D.

An important feature of the invention lies in the improved handle connection, whereby the handle may be detached or securely fastened to the mop head, and lowering of the handle permitted without detachment or ref cured by screws or other suitable fastening means to the top of the segment A. For all purposes, however, the two disks e, c act toy gether and hence will be referred to in the ensuing description as the disk E. Said disk is provided wih a number, preferably three elongated slots or openings located in circular order near the periphery of the disk. These slots are designated, respectively, by the characters, f, f Interposed between slots f, f and slots f and f2 are holes f3, f4, respectively. Also interposed between slots f2 and f is a series of holes f5. All of the holes f3, f4, f5 are preferably circular in shape or otherwise shaped to make a tight connection with the positioning pins mounted on the handle disk.

The slots f, f, f2, however, permit a limited amount of sliding movement of the positioning pins on the handle disk when inserted therein. Centrally located on disk E is a. tubular bearing member E which, as will be seen in Fig. 4, projects laterally from one face'of disk E.

The handle H is secured in any suitable manner to the sleeve H. The forward end of sleeve H is cut-away to form a neck /L which terminates in a disk K. Disk K and sleeve H are, in the preferred construction, integral and may be conveniently made of sheet metal. Projecting centrally from disk K is a bearing pin 7c and arranged in a series around said bearing pin 7c are the positioning pins, preferably three in number, these being designated by the characters Zt, k2, 71:3. The positioning pins project laterally in the same direction as the bearing pin 7c but are preferably somewhat shorter in length. Pivotally secured at Z to the neck z, is a clamping yoke L. The inner arm of the clamping yoke L is provided with a curved slot L and the outer arm with a lateral projection L2 whereby the neck L may be readily grasped and rotated about its pivot in the manner hereinafter described.

In assembling, the handle H is grasped and central bearing pin 7c is inserted into the tubular bearing E of disk E. The greater length of bearing pin le permits it to act as a guide for the disk K when inserting the positioning pins into the desired c0- iguanas member E the respective positioning pins of disk K may be guided into the selected holes. When this is done yoke L is grasped and rotated on its pivot in a direction to slide it over the assembled disks K and E to lock them against lateral movement. During this movement of the yoke L tubular bearing E of disk E enters slot L', as will be apparent from Figs. 2 and 3. lf, on the other hand,lthe positioning pins of disk K are inserted into slots f, f', f2, when assembling the disks, a limited movement of the/ pins is permitted in said slots, without de" stroying the clamping effect of the yoke L. 'llhis permits the handle H to be lowered, for instance, from the position illustrated in Fig. 3, to the nearly horizontal position shown in Fig. 2, the positioning pins sliding in the slots during this movement of the handle member and resulting in a relative movement of the assembled disks in their planes about the axis of central bearing pin In'. rllhe result is that when the parts are clamped together in this manner the 'handle is free to be raised or lowered as desired and the mop or other like article clamped thereon may be easily pushed into locations such as would be ordinarily inaccessible if the handle were xedly clamped in its elevated position.
