. 6, 1949 M. c. McDERMo-r'r MOP HEAD FRAME FOR INTERCHANGEABLE MOP HEADS Filed Jan. 8, 1946 'Ful Patented Dec. 6, 1949 UNITED STATE MOP HEAD FRAME FOR INTERCHANGEABLE MOP HEADS Matthew C. McDermott, White Salmon, Wash. Application January 8, 1946, Serial No. 639,836

1 Claim.

The present invention relates to new and useful improvements in mops, and more particularly to means for interchangeably attaching Various types of mop heads to the mop whereby to enable use of the mop as a dust mop, polishing mop or for other purposes where a cleaning implement of this character is desired.

More specifically, the invention embodies the provision of an open frame to which the mop material is removably secured and embodying means for swivelly mounting a handle to the frame for manipulating the mop.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in use, relatively inexpensive to manufacture, and otherwise Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view with parts broken away and shown in section.

Figure 2 is a transverse sectional view taken substantially on a line 2-2 of Figure 1.

Figure 3 is an enlarged longitudinal sectional view of the frame of the mop head.

Figure 4 is a fragmentary sectional view of one form of removable cover for the frame.

Referring now to the drawing in detail', wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a frame including a vertically disposed band arranged to form an open quadrangular enclosure, the frame being constructed of any suitable rigid material and preferably having its corners rounded, as indicated at 6, and with one end of the frame inclined and slightly curved, as shown at 1.

The front and rear bottom edges of the frame are connected by a transverse plate 8 having a stud 9 rising therefrom and formed at its upper end with a ball or knob I0.

The handle for the mop is shown at II which is preferably of wood construction and is provided with a screw I2 threaded in its front end.

The outer end of the screw projects forwardly of the handle and is split to provide resilient clamping jaws I3, the opposed faces of the jaws having recesses I4 therein to conformably receive the ball I0 to thus provide a socket for swivelly connecting the handle to the ball.

A bolt and wing nut I5 connect the jaws I3 adjacent their inner ends to place the socket at the outer ends of the jaws in properfrictiongripping relation with the ball.

A flexible cover I6 which may be formed of cloth, heavy paper or other suitable material is cut to a shape conforming to the frame 5 and is formed with a hem Il at its edges in which a drawstring I8 isloosely positioned and tied, as shown at I9.

The cover I5 is placed under the 'bottom of the frame 5 with its edges extending upwardly over the front, rear and ends of the frame and with the hem Il and drawstring I8 positioned inwardly of the frame, as shown in Figures 1 and 2 of the drawing, the tying of the ends of the drawstring thus securing the cover against removal on the frame.

To the bottom of the cover I 6 are secured groups of strands of mop materal 20 which may be of any suitable material, such as cloth, paper or the like, the mop material being secured to the cover by stitching 2| or other conventional form of attaching means.

From the foregoing it will be apparent that various types of mop covers I6 and mop material 20 may be secured to the frame 5 and removed therefrom when desired for cleaning, or for disposal where the mop cover and material are constructed of paper.

The mop head may be constructed of any suitable size, which with the swivel mounting for the head gives the advantage of working through any space the width of the head.

It is believed the details of construction, manner of use and advantages of the device will be readily understood from the foregoing without further detailed explanation.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention, the same is susceptible of certain changes fully comprehend ed by the spirit of the invention as herein described, and the Scope of the appended claim.

Having thus described the invention, what I claim is:

A mop head frame including a vertically disposed iiat band arranged to form an open quadrangular enclosure, said band comprising parallel side members disposed in horizontal spaced relation, non-parallel end members disposed in horizontal spaced relation and connecting said side members, a transverse plate centrally positioned within said enclosure adjacent the bottom thereof and connected to said side members, a ball stud 3 disposed vertically on said plate intermediate its ends thereof and adapted to engage a socket carried by a mop handle for swivelly connecting the handle to said frame, and a mop head including a hem having a drawstring therein adapted to be positioned over said band, said hem extending over the top edge of the band with the drawstring positioned interiorly thereof for securing the mop head to said band, one 'of said'non-pai'llel end members being arcuate and forming an `'acute angle with one of said side members for mopping in restricted spaces.
