MOP

Filed Oct. 6, 1937 Mw/rrk Patented Apr. 15, 1941 MOP Isaac A. Myers, Monrovia, Calif., assignor, by

direct and mesne assignments, to- Beverly Holdings, Ltd., Los Angeles, Calif., a corporation of California Application october s, 1937, serial No. 167,600 f 3 Claims.

My invention relates to a mop and method of producing same, and has for its principal object, the provision of a relatively simple, inexpensive and easily practiced method of producing strong, durable and lefficient mops from strands of yarn-like material, and which strands are interwoven with Warp threads and the yarnlike members which constitute the filling or body of the mop and the warp threads being rmly held in assembled relation by a tying-in thread or cord.

While my invention relates particularly to mops and a method of producing same, it is to be understood that my improved method of weaving and assembly of threads, strings or yarnlike members may be advantageously employed in the production of fringe or like trimming mal terials.

Further objects of my invention are to provide a mop wherein the interwoven portions of the f a mop wherein the lling and warp threads are tied together at the points where the same are interwoven, so as to minimize the tendency of the weft or filling members to pull away from the warp threads in the event that the outer portions of the filling members are caught in cracks in the oor, or in articles of furniture and the like, that are positioned upon the oor,

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:

Fig. 1 is a top plan view of a mop produced in accordance with my improved method.

Fig. 2 is a plan view of a portion of a mop produced in accordance with my improved method, and with the threads and yarn-like members that compose the mop in open or extended positions with relation to each other, in order to more clearly illustrate the positions of the warp threads, the filling members and the tying-in thread.

Fig. 3 is a sectional view showing a plurality l of layers of the woven material arranged in superimposed relation, so as to form a mop having a plurality of thicknesses.

Fig. 4 is a detail section taken through the interwoven portion of atubular form of mop.

` Fig.v 5 is a detail section showing the arrangement of the warp and filling threads, also the tying thread along the side of the interwoven portion of a tubular mop.

Referringy by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, I0 designates the filling or weft threads of the mop, I I the warp threads and I2 the tie-in thread.

The lling or weft members are formed from suitable fibrous material, preferably cotton yarn, and during theweaving of the mop, a single continuous strandv of this filling is Caused to travel first in one direction and then in another, thus forming a pluralityV of parallel iilling members; and. during the weaving operation, or thereafter, the half loops that connect the ends of the parallel portions of the filling members, are cut at the points indicated by the dotted lines a, and thus the filling IU of the completed mop, is composed of a plurality of yarn-like members of uniformlength.

Interwoven with the central portions of the weft or filling members I0 are the warp threads II, which are generally smaller in diameter and more iirmly twisted than `the yarn-like members, and these warp members pass alternately over and under the filling members during the weaving operation.

During the interweaving of the weft or filling members and the warp threads, a single tie-in thread I2 is interwoven with the filling and warp threads so that portions of said tie-in thread lie parallel with the weft or filling members I0, such portions being designated by the numeral I3 and shorter portions of the tieing-in thread lie parallel with the warp threads at the sides thereof as designated by the numeral I4.

In Fig. 2 I have shown the portions I3 of the tieing-in thread arranged between every two of the filling or weft members I0, but it will be understood that this arrangement may be varied so that the portions I3 pass between every three, four, five or more of the weft threads.

While the purpose and function of this tie-in thread is to prevent the warp threads from spreading apart, said tie-in thread also strengthens the inter-engagement of the interwoven portions of the lling members and Warp threads.

The portions I4 of the tieing-in thread lie beyond the outside members of the warp threads, said portions I4 occupying positions at right angles to the weft or lling members.

ble flexible water-proof substance, for instance rubber cement, or the interwoven threads may be secured to each other by stitching, stapling or otherwise.

In the accompanying drawing, I have shown the warp threads Il passing alternately below and over pairs of the weft or lling members I0, and while such arrangement is desirable and easily accomplished, it will be understood that such arrangement may be varied and the warp threads passed alternately over and beneath the individual weft or lling members, or over and beneath three or more of said filling members.

In Fig. 3 I have illustrated a plurality of fabric members woven in accordance with my invention, which members are disposed in superimposed relation so as to form a relatively heavy mop composed of several thicknesses of material, and in such construction, the interwoven portions of the lling members and warp threads may be connected in any suitable manner, for instance by stitching, tying or with staples.

In Figs. 4 and 5 I have illustrated a mop constructed in accordance with my improved method, and which is made up of two layers of -fabric, each layer composed of lling members, warp threads and a tying-in thread and with the sides of the interwoven portions united by the two outside warp threads which pass alternately above and below four of the filling members, thus forming between the connected side portions, a tubular structure adapted to receive the frame or head of certain types of mops now in general use.

Thus it will be seen that I have provided a relatively simple and easily practiced method for producing mops and the mops produced in accordance with the method herein disclosed possess superior advantages in point of simplicity, durability and general eciency.

Among the specially advantageous features of any invention are the tying together of the interwoven portions of the lling members and warp threads, and the provisions of the selvedge ends formed by interweaving the ends of the warp threads with the end portions of the tying-in thread.

I claim as my invention:

1. As a new article of manufacture, a mop comprising a plurality of weft or llling members of uniform length disposed side by side, a plurality of warp members al1 interwoven with the central portions only of said filling members and a tying-in thread interwoven with said warp threads, with at least two of the weft threads disposed between those portions of the tying-in thread that are interwoven with said warp threads.

2, As a new article of manufacture, a mop comprising a plurality of layers disposed in superimposed relation, each layer comprising a plurality of weft or filling members of uniform length arranged side by side, a plurality oi warp members all interwoven with the central portions only of the lling members of each layer and a tying-in thread interwoven with the warp threads of each layer, with at least two of the weft threads disposed between those portions of the tying-in thread that are interwoven with said warp threads.

3. As a new article of manufacture, a mop comprising a plurality of weft threads of uniform length and disposed substantially parallel with each other, a plurality of warp threads interwoven with the intermediate portions only of said weft threads, with the ends of said warp threads projecting substantial distances beyond the sides of the body of weft threads, a tying-in thread interwoven with the warp threads and the ends of said tying-in thread being interwoven with the projecting end portions of the warp threads to form selvedges that project substantial distances from both sides of the central portion of the mop.
