Application December 4, 1950, Serial No. 199,068

9 Claims. (Cl. 15118) My invention relates to a mop, more particularly for use in mopping oors or the like, and the objects of my invention are:

First, to provide a mop of this class having a group of mop yarn stationarily fixed to the mop head, and a secondary group of mop yarn pivtally mounted below the first-mentioned group, providing optional use of the mop as an oil mop or a dry mop, as desired;

Second, to provide a mop of this class which may be convertedfrom an oil mop to a dry mop with a minimum amount of effort;

Third, to provide a mop of this class having a novel grommet for connecting the handle thereof to the mop head;

Fourth, to provide a mop of this class having a novel detent means for holding a pivoted group of mop yarn in certain relationship to a group of mop yarn stationarily connected to the mop head of said mop;

Fifth, to provide a mop of this class which is particularly adapted to operate in confined places;

Sixth, to provide a mop of this class which is very light and compact in proportion to its utilitarian functions'as either an oil mop or a dry mop; and

Seventh, to provide a mop of this class which is very simple and economical of construction, efcient in operation, and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, forming a part of this application, in which:

Fig. l is a top or plan view of my mop Fig. 2

` is a side elevational View thereof, showing a portion of the handle broken away; Fig. 3 is an enlarged fragmentary sectional view, taken from the line 3-3 of Fig. l, showing the mop yarn of the mop omitted to facilitate the illustration; and Fig. 4 is an enlarged fragmentary sectional view, taken from the line 4-4 of Fig. 3.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The mop head I, handle grommet 2, mop head cover 3, yarn cape 4, elastic 5, yarn arm 6, yarn arm cover 'I, mop yarn groups 8 and 9, straps II) and II, and the handle I2, constitute the principal parts and portions of my mop.

The mop head I is a substantially rigid'member, preferably of elliptical shape, and this mop head I is provided with central opening Ia therein, in which the resilient rubber grommet 2 is fixed at its flange portion Ib by means of the annular ring ic, which is pressed into the enlarged diameter portion Id of the opening Ia. Thek resilient grommet 2 is preferably made of rubber or the like, and frictionally engages the outer side of thev handle l2 in surrounding relationship therewith, near the normally lower end thereof, as shown best in Fig. 3 of the drawings.

The upper side of the mop head I curves downwardly and outwardly toward the outer edge thereof, and is engaged by the resilient fabric yarn cape 4, which is provided with a resilient bead 4a substantially inwardly and above the outer edge of the mop head I, and supported on this yarn cape 4 is the mop yarn group 8, as shown best in Figs. 1 and 2 of the drawings. `This mop lyarn group 8, fixed to the yarn cape 4, extends outwardly and downwardlyfrom the mop head I, and pivoted to the middle portion of the yarn cape 4 is the arm 6, which supports the yarn group 9 on an axis laterally of the ,longitudinal axis of the mop head I. y

The arm 6 is preferablylmade of wire or the like, and is U shaped, asl shown in'Fig. 4 of the drawings, and is provided with pivotal bearing portions 6a and Sb, which are held within the yarn arm cover 1 at the seam connection 1a, which supports the yarn arm cover 1 on the lower side of the yarn cape 4. Extending outwardly from the bearing portions 6a and 6b is the lever portion Bc, over which the elastic strap 5 extends. This elastic strap 5 is fixed at its opposite ends 5a and 5b to the lower side of the yarn cape 4, and acts as a detent over the lever portion 6c for maintaining said arm 6 in certain adjacent relationship to either end of the mop head I, below the yarn group 8.V

It will be noted that the yarny group 9 is supported on the yarn armcover "I, which'` is a fabric cover, shown in Fig. 3 of the'drawings, and that opposite sides of the yarn group 9 may be used for different purposes, as desired.' One side of the yarn group S may be used as an oil mop for oiling floors, while the opposite side of the yarn group 9 may be a dry mop for dusting. It will be noted that the pivotal movementA of the yarn group 9 on the arm 6 permits opposite sides Yof said yarn group 9 to be employed optionally, and the respective portion of the yarn group 8V exposed downwardly cooperates with each' side of the yarn group9"in certain positions.

It will be noted that a portion of the yarn group 8, from the middle of the mop head i toward one end, may be used as an oil mop, while the portion from the middle of the mop head toward the opposite ends thereof may be used as a dry mop.

The straps IB and Il are secured to the arm 6, and provide means engageable with a persons foot for pivoting the arm 6 from one end to the other of the mop head l, as indicated by the arrows A and B, in Fig. 2 of the drawings.

The handle I2, in its connection with the resilient grommet 2, is movable in any desired direction, as indicated by dash lines in Fig. 3 of the drawings, and may be used to support the mop and move the same during the use of the straps lo and Il, hereinbefore described.

The operation of my mop is substantially as follows:

When the mop is used as an oil mop, one side of the yarn group 9 is disposed downwardly by certain'disposition of the yarn arm 6, and the adjacent portion of the yarn group 8, as hereinbefore described, is cooperative. Thus, one half of the yarn group 8, beyond the pivotal connection ofthe arm B, may be oiled, and the other half may remain dry.y Correspondingly, the opposite side of the yarn group 9 may be dry, so that Isimple pivotal movement of the arm 6 converts the mop from an oil mop to a dry mop, or from a dry mop to an oil mop, as desired. `The elastic 5 slides over the lever 6c during movenient of the lever 6, and maintains the same in certain adjusted position during the use of the mop. When it is desired to pivot the yarn group 9 lfrom one position to the other, as indicated by the arrows A and B, the straps l0 and Il afford a holding means, which may be engaged by a persons foot, so that simple movement of the handle in a lateral direction causes the straps IVD and ll to pull the arm 6 in a direction as indicated by either of the arrows A or B, causing the lever portion 6c to traverse theelastic 5.

A s shown in Fig. 2 of the drawings, the oiled side of the yarn group B bears against the oiled portion of the yarn group 8 and the dry side of the yarn group Bprovides a continuation of the lower-mopping surface of the Inop, together with therdry portion of the yarn group 8.

Though I have Shown and described a particuiar construction, combination, and arrangement cf parts and portions. I do not wish t0 be limited to this particular construction, combination and arrangement but desire t0 .include in the scope .0f mv invention the construction. combination and arrangement substantially as set forth in the appended claims.
