To all 1in/wm t may concern.'

Be it known that I, JOHN R. VAN DYNE, a citizen of the United States, residing at Sedalia, in the county of Bettis and State of Missouri, have invented certain new and useful Improvements in Dust` Mops, of which the following is a specification.

My invention relates to mops, andmore particularly to mops in which the mop material or brush portion is detachably secured to a frame or head.

Specifically, the present invention is designed as an improvement over the construction of mop shown in Patent No. 1,081,225, granted to Il. L. Feasel, Dec. 9, 1913.

One object ofthe invention is to simplify and cheapen the construction of the Feasel device without sacrificing any of its 'advantages. l

Another object is to provide a Vmop head of novel form especially designed to elliciently enter corners and under furniture and the like.

In order that my invention may be readily understood, reference is had to the accompanying drawing, forming part of this specification, and in which,

Figure 1 is a plan view of my improved mop complete; Fig. 2 is a side elevation from the rear of the mop head alone; Fig. 3 is a vertical longitudinal section showing the manner of assembling the parts of my improved mop; and, Fig. 4 'is a similar section substantially on the line 3 3 of Fig. 1.

Referring to the drawings in detail, I construct my improved mop head of only three pieces, such pieces comprising a pair of plates or sections A, B, and a coupling or socket member C. Each plate A and B is dish-shaped in section and consists of a flat bottom 1 provided with an upstanding marginal flange 2. This flange is bent first inwardly and then outwardly into concave form so as to provide an annular groove 3, extending around the head.

By reference to Fig. 1, it will be noted that I prefer to make my improved mop head of trapezoidal form having comparatively long parallel front and rear edges, and comparatively short converging ends, the front edge being longer than the rear edge, whereby acute angles are formed at the front corners at each end, as indicated at 4. These angles or corners are particularly effective in cleaning corners of rooms, l

and the rotation of the parts about such hinge is limited by the abutting edges 3a of the upstanding flanges. lll/'hen these edges are in engagement the sections A and B are in alinement as shown in Figs. 1 and 4. Around the base of the flange adjacent the bottom 2 may be formed a number of small holes 6, so that oilA or the like poured into the `dish-shaped head may flow laterally through such openings and impregnate the mop material.

The coupling or socket member comprises a relatively small flat plate from which projects a suitable socket 8, preferably internally screw threaded to receive a handle, (not shown). The plate 7 is rigidly secured, as by rivets 9, to one section, such as A, and extends across the hinge so as to overlie the other section B. A screw stud 10 projects upwardly from the bottom of section B, and is adapted to pass through an opening 11 in the plate 7. A thumb nut 12 is adapted to engage the stud 10, and when screwed down firmly, serves to lock the sections A and B rigidly together in perfect alinement, as shown in Figs. 1 and 4.

The mop is in the form of a ring of fibrous material 14, provided around its upper edge with a flexible binding 13 adapted to lie in the groove 3 formed in the flange 2.

It will be apparent that when it is desired to assemble the parts, the thumb nut 12 is removed and the sections swung about the hinge into some such position as shown in Fig. 3. The flexible binding of the mop is then placed in the grooves at the outer ends of the pivoted sections and yby pressing downwardly on the socket member the sections are brought into alinement, as shown in Fig. 4, exerting an expanding toggle ac tion and firmly tensioning the binding 13 in the groove. The binding is most tightly gripped at the points where it passes around the acute angles 4, as indicated at 15 in Fig. 4.

It will thus be seen that instead of employing a dish-shaped plate and a toggle plate in addition, as in the Feasel construe-Vv tion, I eliminate one of ythese plates and hinge-the dish-'shaped'plate itself so asy to provide a toggle action.'l In rother' words, my improved mop head consists of but a single plate formed o two sections, and a socket member which serves to holdthe sections in aliilement.`
