UNITED STATES PATENT OFFICE Application August 26,

14 Claims.

My invention relates to improvements in mops or clusters, and it particularly relates to that type cf mop or duster designed for polishing or dusting floors.

Mop heads now in general use are of a form having both transverse and longitudinal dimensions appro'xirnating each other, oftentimes being circular in form, many being more or less heartshaped, and others having varying forms, but all being more or less rigid so that it is necessary to move furniture about in order to properly dust or polish a floor; failure to do so resulting in the furniture being bumped and marred by reason of the fact that no yielding or flexible and especially no resilient parts are provided to come in contact with the furniture. Moreover, considerable difliculty is encountered when attempting to thrust the mop head into corners or small spaces more or less inaccessible.

The primary object of my invention is the provision of a polishing or dusting mop having slender resilient portions readily insertable into spaces usually considered inaccessible and surfacepadded or cushioned so that when coming in contact with an article of furniture or other object they will become flexed and be self-conformable to the spaces through which the mop head is to be thrust; such flexed portions being self-recoverable to normal shape after passing through the spaces.

Another object of my invention is the provision of a mop head which is inherently resilient and capable of being used in a substantially rectilinear form with a handle disposed at a right angle thereto, yet being capable of being flexed with a View of bringing the opposite ends thereof together to form a mop head of the conventional type, or closely approaching such a type, and in which the swab portion of the mop is fashioned into a form approachingthe outline of a heart and approximating dimensions in directions at right angles to each other which closely approach each other.

A further object of my invention is the provision of a resilient normally rectilinearly disposed mop or duster swab adapted for use in small spaces and provided with means at opposite ends to connect said ends together when flexing the swab so as to approximate the usual outline of a polishing or dusting mop in which the dimension of the head in one direction approximates that at a right angle thereto.

A further object of my invention is the provision of a mop or `duster head which is inherently resilient and normally retained in a straight- 1933, Serial No. 686,973

lined condition, said head being flexible under strain so that when passing it between the legs of two articles of furniture, or between other spaced objects, the mop head may be thrust through such space, even though considerably smaller in dimension than the normal length of said mop or duster head, said head having a handle secured between its ends so as to provide opposite resilient portions capable of being flexed individually or together in one direction to like or different degrees upon pushing or pulling the mop, depending upon the obstructions which it encounters under operation of the user.

A further object of my invention is to provide the conventional swab comprising assembled strands of cotton or the like arranged in an extended series and having canvas or other flexible material secured to opposite sides of the series of strands to provide a tubular upper portion for the swab into which a resilient metallic strip is adapted to be inserted, said strip being retained within said tubular upper portion in any approved manner, but preferably with screws or other fastening means serving to secure handle brackets to the swab.

With the above and other objects in View to appear hereinafter, my invention consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.

In the drawings:

Fig. 6 is an enlarged cross section through the upper portion of the mop head showing the resilientv retainer strip inserted therein.

Fig. 7 is an enlarged longitudinal section through the mop head taken on line 'I-'I, Fig. 3.

Fig. 8 is a perspective View of the mop showing the end portions of the mop head iiexed to bring their free extremities together and showing these extremities connected to form a mop head approximating the form of mop heads now in general use.

In the form in which my invention is illustrated, it comprises two main parts 9, I, which I respectively term the mop head, and the handle secured to the mop head.

The mop head is formed of metallic parts and textile material, the textile material forming the swab, which in the main does not differ from swabs now used in polishing mops. The swab designated by the numeral II is constructed of parallel strands of cotton or the like arranged in an extended series to form a comparatively thick layer. At opposite sides of this layer of strands strips of cotton or other sheet material is placed, the textile structure thus formed being sewed along the edges of the strips of cotton and through the strands of fiber, after which the structure is folded centrally along the strips of cotton and sewed together to form a tubular upper portion I2 for the swab. This tubular portion is comparatively fiat, and from the lower edge thereof the strands of cotton depend in a thick mass so as to form a comparatively flexible brush-like portion I3 of any desired height. The swab thus formed is therefore of a type in ccmmon use and it has a flexible or inherently resilient retainer strip I4 inserted into its tubular upper portion which is normally straight-lined so that when inserted into the swab the latter will be normally straight-lined from end to end.

Midway between its ends, the swab has suitable handle-fastening elements secured to one side of the tubular upper portion thereof, the elements being in the form of angular brackets E5 which are spaced apart, as at I6, and are secured to the swab by means of screw bolts il, or in any other approved manner. The screw bolts I'I are passed through the brackets, through the tubular uppei portion of the swab and through a plate I8 co-extensive with the brackets I5 and the space between them, nuts I9 being applied to the ends of the screw bolts and bearing against the plate I8.

Attention is directed to the fact that the resilient retainer strip I4 is held against movement within the tubular upper portion of the swab, and while this may be accomplished in any desired manner, I preferably provide this strip with notches 2E] at its upper and lower edges through which the screw bolts I1 are passed, thus preventing endwise movement of the strip and guarding againt the strip projecting from the ends of the tubular portion of the swab and causing furniture or other objects to be scratched or otherwise marred. The swab, the resilient retainer strip, the brackets I5, plate I8, and screw bolts I'I constitute the mop head.

The handle has a metallic ferrule ZI at its inner end which is formed of a sheet metal sleeve pressed together along a portion of its length to form a flat securing part 22 through which a bolt hole 23 is formed, and this bolt hole, when the ferrule is thrust between the brackets I5, is alined with bolt holes 26 in said brackets. Through the alined bolt holes a pivot bolt 25 is passed, the head of the bolt bearing against the outer side of one of said brackets, and a wing nut 26 threaded onto said bolt bearing against the outer side of the other bracket. Thus the handle i@ may be positioned in any angular relation with respect to the mop head and be thus retained upon tightening said wing nut,...

It will be apparent from the foregoing that I have provided a straight-lined flexible mop head and, by reason of the handle Ill being secured thereto midway between its ends, resilient opposite end portions are provided which are normally retained in alinement with each other by the resilient normally straight-lined formretaining strip III inserted into the tubular portion of the swab.

As clearly shown in Fig. 2, when moving the swab in the direction of the full-lined arrow with free space to one side of a plane passing axially through the handle and a chair or desk leg encountered at the other side thereof, as indicated at 21, the swab head will be exed at one side of the handle so as to move in contact with said leg without causing injury thereto while the mop head at the other side is retained in straightlined condition. Continued movement of the mop in the direction of said arrow will result in further flexing of the mop head at one side of the handle so that the mop can be advanced forwardly and entirely clear of the desk or chair leg and proceed to polish or dust the floor beyond the leg. The mop head is then maintained in straight-lined position, due to the fact that the flexed portion of the mop head will have been returned to its normal straight-lined condition under the inherent resiliency of the form-retaining strip I4 therein; such action occurring as soon as the end of the flexed portion clears the desk 0r chair leg.

When drawing the mop in a reverse direction, as for example indicated by the dotted arrow in Fig. 2, that portion of the mop head previously flexed toward the free end of the handle will be exed in a reverse direction-as indicated by the dotted lines at 28. Any obstruction encountered at the opposite side of the handle would cause flexure of the mop head on that side in the same manner as described with reference to the portion of the mop head encountered by the chair leg or desk leg 2.

By reason of the mop head being comparatively long and slender, either end thereof can be thrust into comparatively small spaces, such as are normally considered inaccessible to the conventional mop head. Thus my improved mop assures cleanliness in the remotest corners, as well as in the more exposed portions of a floor.

While I have referred to the mop head as being particularly adapted for polishing or dusting floors, it is quite apparent that the brackets I5 and plate I8 at opposite sides of the tubular portion of the swab form a rigid center, and these or some other medium providing a rigid center may be used as a hand grip after removing the pivoted handle IG from the swab head. In such cases the mop head could be employed for dusting furniture and other articles, or such use may be provided for the rnop head by merely shortening the handle IE).

It is, of course, understood that mop heads constructed according to this invention may be made in various lengths, depending on the conditions under which and surroundings at which they are to be used. In large quarters, such as hotel lobbies and the like, a comparatively long straightlined mop head would be of advantage over one of medium length, and since in some instances the purchaser may desire to use the mop in a form approaching those now in common use, I have provided means for connecting the ends of the normally straight-lined mop head together after flexing the portions of the mop head extending from opposite sides of the handle connection thereof. This may be accomplished in various ways, but I have provided a means which will in no manner interfere with the operation of the mop head while in straight-lined form, nor will it in any manner cause furniture or other objects to be marred.

With this in View, I provide at either the front or rear side of the swab at opposite ends thereof, tie straps 29, which may be strips of cotton or any other suitable material attached to the textile strips forming the tubular portion of the swab by the same stitching employed to form said tubular portion. These tie straps dangle downwardly from the tubular portion of the swab in the same manner as the cotton strands forming the brush portion of the swab, and it is only necessary to flex opposite portions of the swab, either forwardly or rearwardly, with a view of bringing the free extremities thereof together, after which they may be so retained by the tie straps 29.

In Fig. 8 I have shown the resilient portions of the swab bent rearwardly or in the direction in which the handle l extends, and whether or not the tie straps are at the inner or outer side of the swab, they may be easily tied together, as shown at 3B. In this manner a swab head is vformed which has considerable dimension longitudinally and transversely, in contradistinction to the straight-lined dimension illustrated in Fig. 1. However, thus arranged it would be as difficult to operate the mop over a floor with furniture or other objects arranged close together, and as in the ease of the mops now commonly in use, it would be found necessary to move the furniture. in order to properly polish or dust the iioor. However, since with somel purchasers accustomed to using a two-dimensioned swab, it may be found desirable to employ my improved swab in the form shown in Fig. 8, especially when there is a desire to clean in a superficial or haphazard manner. In the event, however, of a careful cleaning being considered advisable, and the mop is to be used in its normal one-way extended manner, it is simply necessary to untie the tie straps 29, whereupon the inherently resilient form-retaining strip I4 will snap into straightlined form and thus retain the swab in a straightlined condition. It is, however, to be understood that the swab head may be one-way extended, yet be otherwise than straight-lined.

By securing the handle to the mop head midway between its ends and providing a transversely extended fastening element, a rigid central portion is provided for the mop head, at opposite sides of which are resilient portions self-con formable to spaces larger than the rigid center portion and smaller than the maximum straightlined length of the mop head, said resilient portions being subjected to degrees of flexure according to the width of the spaces through which the mop is being passed and the obstructions encountered and returning into alined relation immediately resistance to advancement under pulling or pushing strain ceases, such strains being created by the resilient portions coming in contact with obstructions.

It will be apparent from the foregoing that I have provided what may be termed a single or one-direction mop head formed of a single strand swab which is inherently resilient by reason of the fact that it has built into it a metallic resilient element which is straight-lined, or substantially so, and thus provides a frameless mop head which differs from any other mop head known, in that a rigid intermediate portion is provided merely by means ofthe connection of a handle thereto and free unrestrained resilient outwardly-extending portions which possess equal resiliency-in both forward and rearward directions, which results in a mop head capable of being inserted into small spaces larger than the rigid portion of the mop head and smaller than the longitudinal dimension of said head.
