An important object of the present invention is the provision of mop head mounting hardware whereby a mop head may be mounted on a mop handle with positive security limited only by the structural strength of the parts and in no way dependent on springs or other resilient means for holding power, but which nevertheless provides for easy and instant detachment of the mop head from the handle when desired, as for examfile interchanging, cleaning, or servicing the mop Another object is the provision of mop hardware of the character described which holds the mop head for pivotal movement about a horizontal axis transverse to the mop handle, whereby the mop head, which is most commonly generally planar in shape, will rest flat on the floor despite the constantly varying angle of the mop handle relative to the floor which occurs in normal usage. This pivotal movement is virtually always desired.

A further object is the provision of mop hardware of the character described which provides not only for pivoting of the mop head about a horizontal axis as already mentioned, but also for pivoting of the mop head about a second axis also transverse to the handle, but disposed at right angles to the horizontal axis. The resulting universal pivoting of the head is useful in guiding the mop head around and between obstructions which may be encountered on the floor during use of the mop.

A still further object is the provision of mop hardware of the character described providing universal pivoting of the mop head, in which pivoting about the non-horizontal axis may be selectively used or not used, as desired.

Other objects are extreme simplicity and economy of construction, efficiency and dependability of operation, and adaptability for use with mops of many different types and styles. I

With these objects in view, as well as other objects which will appear in the course of the specification, reference will be had to the accompanying drawing, wherein:

FIG. 1 is a top plan view of a mop head and handle, shown operatively connected by a mounting embodying the present invention,

FIG. 2 is an enlarged, fragmentary sectional view taken on line II-II of FIG. 1 with the mop head omitted,

FIG. 3 is a view similar to FIG. 2, with the spool lock released for detachment of the mop head,

FIG. 4 is a fragmentary'sectional view taken on line IV-lV of FIG. 2, and

FIG. 5 is a laid-out view of a blank from which the barrel may be formed.

Like reference numerals apply to similar parts throughout the several views, and'the numeral Zapplies generally to a mop head of a common type, consisting of a backing 4, usually formed of cloth or the like, to which the mop yarn 6 is stitched or otherwise attached. The backing, as shown, is generally ovate in shape, and forms a pair of pockets 8 confronting, in opposed relation, a window 10 formed therein centrally of its length.

A mop head frame includes a generally oval loop 12 of heavy wire stock, the ends of which are adapted to be inserted respectively into pockets 8 through window 10. The backing 4 may be elastic, or the top layer thereof may be detachably connected to its lower layers, or the loop 12 itself could be constructed so as to be foldable transversely to its plane, in order to permit this insertion. A pair of bars 14 extend in parallel relation across loop 12, extending fore-and-aft in symmetrical disposition to the longitudinal midpoint of said loop, and are welded at their ends to the front and rear reaches of said loop. The central portions of bars 14 are offset upwardly to project upwardly through window 10, and a horizontal cross bar 16 extends between and is welded to the midpoints of bars 14, cross bar 16 being parallel to the major axis of loop 12. The structure of the mop head and its frame may take many forms, and the specific structure thereof is not particularly pertinent to the present invention. The only essential feature thereof, in order that it may be used with the hardware forming the subject matter of the present invention, is that it include a cross bar similar in disposition to that of cross bar 16.

The mop handle mounting hardware as contemplated by the present invention includes a spool 18 constituting a cylindrical bar having a diameter larger than that of cross bar 16 and having formed longitudinally in one side thereof a groove 20 of suflicient dimension to admit cross bar 16 transversely thereinto. Said cross bar is axially rotatable in said groove. The length of said spool is slightly less than the free length of cross bar 16 between bars 14. At the midpoint of the spool, a pin 22 is fixed therein and extends radially outwardly therefrom in angularly opposite relation from groove 20, said pin being provided at its outer end with an enlarged head 23.

Spool 18 is disposed rotatably in a cylindrical barrel 24 formed of sheet metal and being of slightly less axial length than said spool. Said barrel is angularly interrupted to form a slot 26 extending longitudinally along one side thereof, said slot being of sufficient width to admit cross bar 16 laterally therethrough into groove 20 ofspool 18, when said slot and groove are angularly aligned by rotation of the spool in the barrel. Pin 22 extends through a peripherally elongated slot 28 formed in the barrel. Slidably mounted on the extended portion of said pin is an operating button 30, said button being resiliently biased inwardly toward the spool by a spring 32 disposed thereabout in a socket of said button, and bearing between the base of said socket and the enlarged head 23 of said pin. Said button is also rotatable on said pin, and is provided at its inner end with a neck 34 of reduced diameter. Barrel slot 28 is of sufficient width to admit pin 22 but not neck 34 of the button, except that at one end said slot is enlarged, as indicated at 36 (see FIG. 5) to a diameter sufficient to admit neck 34. When button 30 is urged inwardly by spring 32 to engage neck 34 thereof in slot enlargement 36, as

shown in FIG. 2, said engagement locks spool 18' -mop head frame is securely locked into groove 20,

although it is of course still rotatable therein. When button 30 is pulled outwardly against spring 32 by manual force, neck 34 thereof is freed from barrel slot enlargement 36, freeing spool 18 for rotation in the barrel. Said spool may then be turned in the barrel by lateral pressure on the button to move pin 22 through slot 28 to the opposite end thereof as shown in FIG. 3. This position is the unlocked position of the mounting. Groove of the spool is then angularly aligned with slot 26 of the barrel, and cross bar 16 of the mop head frame may then be moved transversely therefromas indicated by arrow 38 in FIG. 3 to detach the mop head from the handle. The cross bar of a new mop head may then be inserted through slot 26 into groove 20, and

button 30 moved in a clockwise direction, as viewed in FIGS. 2 and 3, until button neck 34 is snapped into enlargement 36 of slot 28 by spring 32, whereupon the mop head is again locked in assembly with the mophandle. v

The sheet metal barrel 24 is provided with a radially projecting ear40 for attachment to handle ferrule 42. Said ferrule is formed of tubular stock, the handle 44, which may of course be of any desired length, being inserted into one end thereof and secured therein by rivet 46 or any other suitable. fastener, while the other end portion of said ferrule is flattened to form a flat tongue overlying ear 40, and pivoted thereto by a shouldered bolt 48, said bolt extending through matching

holes

50 and 52 formed respectively therefor in the ferrule and ear and being secured by nut 54. Said bolt is sufficiently loose to permit freev relative pivotal movement of the mop handle and head about its axis, and is disposed at right angles to, though transversely offset from, the axis of spool '18. Y

Intermediate bolt 48 and barrel 24, a pair of corresponding holes 56 and 58 are formed respectively in ferrule 42 and barrel ear 40. Said holes are so disposed as to be accurately registered with each other only when handle 44 is disposed in normal or right-angled relation to spool 18. Integral with or fixed to lock button 30 is an arcuate finger 60 concentric with barrel 24. When said locking button is moved to its locking position as shown in FIGS. land 2, with neck 34 thereof engaged in enlargement 36 of slot 28, finger 60may enter and extend through holes 56 and 58, thereby locking the mop head and handle against relative pivotal movement on bolt 48. Said finger is withdrawn from said holes whenever button 38 is moved to its unlocked position as shown in FIG. 3. Furthermore, in this position, button 30 may be rotated manually on pin 22 so that finger 60 is angularly displaced out of alignment with holes 56 and 58, as shown in dotted lines in FIG. -3, so that when the button is returned to its locking position, finger 60 will not enter holes 56 and 58, and the pivotal connection provided by bolt 48 will remain free.

The operation of the device is believed to have been adequately described in connection with the above description of its construction. It is considered to have several novel advantages. The mounting is extremely simple, durable and economical in construction. Its operation in connecting or disconnecting a mop head to or from the handle is extremely rapid, simple and convenient. The holding power of the mounting is great, being effective up to the structural failure strength of the parts themselves, and being in no way dependent for holding power on springs or other yieldable elements. It provides at all times for relative pivoting of the mop head and handle on a horizontal axis, this being a movement which is virtually always desired. It also provides for pivotal movement of the mop head relative to the handle about an axis at right angles to and in addition to movement on said firstnamed horizontal axis. The resulting universal pivotability of the mop head relative to the handle is highly desirable when mopping between andaround obstructions with a horizontally elongated mop head, but is usually considered to be objectionable when mopping unobstructed floors. Therefore, the universal pivotability may be used or not used, selectively, as the user may desire.

While I have shown and described a specific embodiment of my invention, it will be readily apparent that many minor changes of structure and operation could be made without departing from the spirit of the invention.
