MOP FRAME AND HANDLE COUPLING.

Specification of Letters Patent.

Original application filed April 17, 1916, Serial No. 91,769. Divided and this application filed December 21, 1917. Serial No. 208,266.

To all whom it may concern:

Be it known that I, FRANKLIN P. Toor,

a citizen of the United States, and a resident of Paducah, in the county of Me- Cracken and State of Kentucky,.have invented a new and useful Improvement in Mop Frame and Handle Couplings, of which the following is a specification. H The present invention relates to mops, and this application is a division of my copending application Serial Number 91,769, filed April 17, 1916, for an improvement in mops.

This application is directed more particularly to an improved connection between the handle and the frame of a mop.

The object of the present invention is to provide a coupling or connection between the handle and the frame of a mop which is simple in construction; which removably supports the handle; which pivotally connects the handle to the frame in such a manner that the user may position or move the mop frame without danger of casual lateral displacement of the frame with respect to the handle; and to provide a coupling which may be formed or stamped from a single blank of metal.

Various other objects and advantages of more or less importance will be hereinafter described, and in part understood, from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein:

Figure 1 is a perspective view of a mop frame and handle connected together by a coupling constructed according to the present invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a side elevation of the same.

Fig. 4 is a detail longitudinal section through the coupling with the handle applied thereto.

Fig. 5 is a detail perspective view of the coupling partly overturned in the process of manufacture.

Referring to this drawing A designates a frame which, in the present instance may be the frame of a mop, and which may be of triangular form as shown. The frame A has an inwardly offset portion B formed with a transverse section or bearing C to which the coupling of this invention may be applied. The frame A is adapted to be is well adapted for use in the supported by a handle I) having a threaded end portion E preferably terminating in a shoulder F.

The coupling is formed of a single elongated piece of sheet metal having a transverse enlargement 10 intermediate its ends,

the enlargement being rounded or bent to form a cylinder of substantial length adapted to embrace the bearing C and form a support therefor. The ends 11 of the coupling extend from the enlargement 10 and are bent throughout substantially their lengths into arcuate cross section, as shown to advantage in Fig. 5, and may be provided with screw threads 12 formed by pressing the metal inwardly, the ends 11 or sections of the coupling being complemental to each other and forming a socket for receiving the screw threaded end E of the handle D.

Each section 11 may be provided with perforated ears 13 in suitably spaced apart relation from the cylinder 10, and the ears of one section abutting against the ears of the other section and adapted to be riveted for preventing casual separation of said sections 11 from operative relation. The threads 12 may extend any suitable distance throughout the lengths of the sections 11, and the latter may be transversel arcuated throughout their entire lengths or stiffening or reinforcing the sections of the cou- 'pling.' When the threaded end E of the handle D is turned into the socket between the sections 11, the shoulder F of the handle is adapted to bear against the free edge of the socket and thus bind the handle in the same.

It is to be observed that the cylindrical portion 10 of the coupling firmly embraces the cross section 0 of the offset B of the frame, so that the frame is permitted to swing about a transverse axis, but .is held firmly against movement about a lateral swinging axis. Because of the pivotal connection of the handle with the frame, falling within the plane of the frame, and substantially midway of the front and back of the latter, is prevented, and the mop itself cleaning of ceilings, walls, etc., and if it is desired to clean ledges, such as plate rails, the frame A may be swung with respect to handle D so that the latter projects below the frame for firmly holding the frame during cleaning.

Patented July 27, 1920.

It is of course understood that various changes and modifications may be made in the details of formation'and design of the above specifically described embodiment of the invention, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:

1. In a mop, the combination of handle,

a frame, and a coupling formed of a single elongated piece of metal overturned intermediate its ends and embracing a section of said frame, and the end portions of said coupling being transversely bent to form complemental socket portions adapted to embrace the end of said handle.

2. In a mop, the combination of a frame having a transverse bearing section, a handle for the frame having screw threads on one end, and a coupling comprising a single blank of metal having an enlargement intermediate its ends and overturned to form a cylinder at said enlargement and having its end portions transversely arcuated to form complemental socket sections and having screw threads in the walls of the socket sections, and means for securing the socket sections together for the reception of the de tachable threaded handle.

'tion of the metal 3. In a mop, in combination with a handle and a' frame, a coupling formed of a single length of sheet metal bent transversely at opposite ends and overturned With the bent ends together to provide complemental socket portions adapted to receive the end of the handle, said overturned porbeing rounded and adapted to engage the frame for hinging the coupling thereto.

4. As an article of manufacture, a coupling for mops formed of a single elongated piece of sheet metal With an enlargement intermediate its ends bent transversely to form a cylinder with its axis crosswise of the coupling, and the portions extending from said enlargement bent to an arcuate cross section, the last mentioned portions being complementary to provide a socket With its axis longitudinally of the coupling.

5. A coupling for mop handles comprising a single length of sheet metal overturned and rounded intermediate its ends to provide a bearing adapted to engage the frame of the mop, the free ends of the sheet of metal being curved transversely and brought together to form a socket adapted to receive the end of the handle.

FRANKLIN P. TOOF.
