UNITED STATES WALTER H. RUDOLPH, OF WEST HARTFORD, AND LOUIS, V. LUCIA, OF HARTFORD,

PATENT, OFFICE,

. CONNECTICUT, ASSIGNORS TO THE FULLER BRUSH COMPANY, OF HARTFORD, CON- NECTICUT, A CORPORATION OF CONNECTICUT.

MOP, DUSTER, AND SIMILAR ARTICLE.

To all whom it may concern.

Be it knownthat we, WALTER H. RUDOLPH and LOUIS V. LUCIA, each a citizen of the United States, and residents, respectively, of WVest Hartford and Hartford, both in the county of Hartford and State ofConnecti cut, have invented new and Improved Mops. Dusters, and Similar Articles, of which the following is a specification.

This invention relates to the class of devices more especially designed for scrubbing and other cleaning purposes, and an object of the invention, among others, is the production of a mop, duster or similar article that shall be particularly efficient for the purposes for which it is designed, that may be constructed in a very simple manner, and that shall be extremely durable.

One form of device embodying the invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a plan view of an implement e1..bodying our invention, the handle being shown as broken off.

Figure 2 is a side view of the same.

Figure 3 is a detail view illustrating a step in the process of forming our improved implement.

Figure 4 is a view similar to Figure 3 but showing another step in the process.

Figure 5 is a view of the mechanism illustrated in Figure 4, but looking in a direction atright angles thereto. 1 'Figure 6 is a view of a portion of an implement produced in accordance with our invention and showing the location of the loops in the twisted wire core.

Figure 7 is a detail view showing the form of the brush just after the twisting operation.

Figure 8 is an end view of the structure shown in Figure 7 While this invention is not limited to a structure of any particular shape, or designed for any particular purpose, yet as it finds ready application in theclass of devices known as dish mops such has been selected for the purpose of illustrating the in vention herein.

The invention is especially applicable to In the accompanying drawings thev numeral 10 indicates the handle of this improved mop that may be composed of any suitable material and to which theshank 11 of a twisted wire core 12 is secured. The mop 13 comprises a mass of loops 14 preferably composed of twisted threads that are secured to the twisted wire core in the operation of twisting such wire, and the mop forming the subject matter. of this invention comprises a plurality of said loops formed from a single strand or thread. The structure as disclosed herein comprises a mop in which all of the loops are formed from a single strand or thread, but it will be understood that it is not essential to the invention that the mop shall be so formed, as the invention contemplates a structure in which any number of such loops may be formed from a single strand or thread.

In the construction of this mop a strand or thread 15 is wound upon a form, and a wire or wires to comprise a core are placed against this wound mass upon opposite sides thereof. The form is then removed and the wire or wires are twisted whereby the several turns of thread are secured and held at their centers thereby producing loops 16. The formation .of these loops andthe manipulation of the threads and wires to accomplish the desired purpose may be efl'ected in many different ways, one of which that has been found to satisfactorily accomplish the desired end being shown herein. This comprises the use of a form consistlng of two members pivotally united and including supporting fingers 17 adapted to be posltloned in substantially parallel relation. These members on that side of the pivot opposite said fingers constitute positioning extensions 18 that serve to properlyposition the supporting fingers to recelve the thread or strand when wound thereon. As shown post projecting from the end of an operating spindle 26 and these fingers 17 are preferably flat and quite thin, this being a very suitable form for producing the loops, and after the thread has been wound upon the "fingers the wire or wires which constitute the core are engaged with theiwound mass upon opposite sides of the wound form. As illustrated herein this wire is composed of a single piece bent to provide two branches 27 that are engaged with the wound mass by inserting the branches between the fingers 17 at that end of the wound mass next to the pivot of said fingers and moving the branches until one end of the wound mass is located close to the bent end of the wire. A holde-r28, herein shown as a ring, is then placed upon the free ends of the wires to prevent them from separating. The clamp 20 is now loosened to release the form and permit it to be removed. When so removed the fingers will close toward each other, thus loosening them from the wound mass and enabling such mass to be removed from the form. Said mass is now held in the form of loops by the wire structure.

The ends of this wire structure are now twisted in any suitable manner, as by placing one or both ends thereof in a chuck or chucks for that purpose, after which twisting and as a result thereof the holder 28 will be loosened so that it may be readily removed. The structure is now in condition .for having such form imparted to it as may of a divisional application filed by us January 12, 1925, S. No. 1857.

A stop is provided to engage between the positioning extensions and thereby define the extent of openingmovement of the support, in the structure herein shown this stop being constituted by the post 25 against whichthe extensions abut in the opening movement of the outer ends thereof. The mops or similar devices illustrated herein are commonly made of twisted threads. altllo such twisted feature has been omitted from some of the views of the drawings herein in order to simplify the illustration. When the ends of such threads are free they readily untwist, this being an objectionable feature. It will be seen that the structures herein illustrated and described avoid such results as there are no free ends to unravel or untwist.

In accordance with the provisions of the patent statutes we have described the principles of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; but we desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out as embodied within the scope of the appended claims.

lVe claim-- 1. An implement of the class herein mentioned comprising a twisted wire core, and loops secured to and projecting through said core to opposite sides thereof, all of said loops being formed from a single strand.

2. A device of the kind described comprising a coreformed of a plurality of wires twisted together, and a strand of mop material formed into a plurality of loops, each having the intermediate portion of its laps clamped between the wires forming the core. 3. A device of the kind described comprising a core formed of a plurality of wires twisted together, a strand of mop material sinuously folded upon itself. to form a plurality of loops divided substantially midway between the looped ends thereof by said core wires between which the strands form ing the loops are clamped.
