Y., assignors to Empire Brushes, Inc., Port Chester, N. Y., a corporation of New York Application June 29, 1955, Serial No. 518,792 8 Claims. (Cl. 15-229) This invention relates to rnops. lt is particularly related to a spaghetti-type or yarn mop.

An object of this invention is to provide a mop of the character described comprising a molded hollow head, a clamp clamping the mop yarn and received within said head and provided with a screw socket itting into a neck in the head, the construction being such that when a threaded end of a handle is screwed into the socket, the clamp is rmly fixed within the head, thus holding the clamp, mop elements and handle in assembled relation with respect to the hollow head.

Yet another object of this invention is to provide a mop of the character described which may easily be assembled and disassembled, which shall permit 'replace` ment of parts and which shall be relatively inexpensive to manufacture degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplied in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

ln the accompanying drawings in which is shown various illustrative embodiments of this invention,

Fig. 6 is a cross sectional View Fig. 4.

Referring now in detail to the drawing, ld designates a mop embodying the invention. The same comprises a hollow head 1l which may be molded of synthetic plastic material. rIhe head il is hollow and open at its underside. lt is formed with a central noch portion ft2 from which extends outwardly top shoulder portions 13 fiar ing slightly outwardly and downwardly. The neck 12 extends up above the shoulders t3 and also is formed with a lower end portion isi projecting downwardly below the shoulder portions i3. Said neck i1?. is formed below its upper end Jiri with an inner annular rib or shoulder "16 for the purpose hereinafter appearing. The top shoulder portions i3 are connected to the neck l2 by central strengthening ribs 1?. Extending downwardly from the outer ends of the top shoulder portions 13 are end walls l, and extending downwardly from the sides taken on line 6-6 of and yet practical and efficient to a high A of said top shoulder portions are longitudinal side walls 19 interconnecting the ends of the end walls 18. The shoulder portions 13 may be of rounded transverse crosssectional shape if desired. The downwardly projecting portion 14 of the neel; l2 has a lower end edge 20 for the purpose hereinafter appearing. Thus, the head 11 is formed with a hollow chamber 2l at its underside opening downwardly. Said side walls 19 and end walls 18 may be formed with a thickened lower end edge bead ft2 extending all around for strengthening` said head.

The mop 1d further comprises an adaptor 25 carrying spaghetti-type yarn mop elements 26. These elements may be made of synthetic sponge material. However, they may be replaced by any other lexible mop elements or fibers. The adaptor 25 comprises an elongated clamp plate 27 which may be made of sheet metal. Said plate 27 has a longitudinal, central, inverted U-shaped portion 28, formed with integral upwardly curved longitudinal lips 29. The inverted U-shaped portion 28 forms an elongated, inverted U-shaped groove 30 at the under side of the plate 27. The ends of the inverted U-shaped portion 23 are notched inwardly as at 31, at both ends, for the purpose hereinafter appearing. Extending about the plate 27 is a wire loop member 33. Said wire loop member 33 has a bottom portion 34 disposed below the plate 27 in spaced relation thereto and located within the inverted U-shaped groove 30. Extending upwardly and inwardly from the ends of said wire portion 34, are curved portions 355 received within the end notches 31. Extending inwardly from the upper ends of the curved portions 35 are aligned wire portions 3d disposed above thc plate Zin spaced relation thereto, The inner ends of portions 36 may be lixed together by welding or in any other manner.

The iiexible mop elements 26 are folded inA half around the bottom wire portion 34 and are clamped by said wire portion 34 against the underside of the clamp plate 27. The mid-portions of said mop elements are hence clamped tight within the inverted U-shaped groove 30.

Mounted on the upper wire portions 36 is a metal sleeve llt). Said metal sleeve dil has downwardly projecting apertured ears 41 through which the wire portions 36 pass. Said sleeve 40 is formed with inwardly punched sets of ridges i2 for receiving a screw threaded member. it will be noted that the plate 27 and the wire member 33 are received within the chamber 21 and that the mop elements 26 project downwardly therefrom. The lower end edge 2@ of the tubular member 12 Contact the wire portions 36 on opposite sides of the sleeve d@ passes upwardly through the neck 12 and its upper end edge contacts the underside of the annular rib or shoulder 16.

The mop is provided with a handle 5G. Said handle 50 comprises an elongated wood rod 51 to the lower end of which is fitted a metal cap d2. Said cap 52 is formed with a portion S251 and a reduced externally screw threaded portion 53. The portion 53 may be inserted through the opening formed by the internal annular rib 16 and is screwed into the sleeve 4l), engaging the ribs 42. Between the portions 52a an` i 53 is formed. a shoulder 54 which contacts the upper side of the annular rib 16. Thus, as the handle is turned for screwing the portion S3 thereof into the sleeve 40, the shoulder 54 contacts one side of the rib i6 and draws the sleeve 40 upwardly against the opposite side of said rib for firmly attaching the sleeve it? and the mop handle to the head. At the same time, the loop 33 is pulled upwardly into the chamber Z1 until it contacts the lower edge 20, thus making an assembly of the mop handle 50, the adaptor 25 and the head 11. The flexible mop elements project downwardly aperture ears 41. The l below the head, so that the rnop may be used. The handle 50 may be unscrewed to disassemble the adaptor 25 with its mop elements from the head.

It will thus be seen that there is provided an apparatus in which the several objects of this invention are achieved and which is well adapted to meet the condition of pra@ tical use.

As possible embodiments might be made of the above invention, and as various changes might be made in the embodiment -above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
