This invention relates to improvements in a mop anddevices of similar character of the type wherein the fabric is readily removable from and replaceable on the head of the device.

In the past, mops and similar devices have been developed to permit the ready removal of the fabric from the element or elements normally holding the same, and the remounting of the fabric. In some instances, such removal and replacement of the fabric may not ofnecessity have been accompanied with is desirable. In many instances, such devices which permitted the removal and replacement of the fabric without the actuation of any mechanical parts, did not hold the fabric in a sufficiently positive manner, but on the other hand would permit the fabric to become loosened if the same caught on any obstruction while the device was in use.

. The present invention has been designed to overcome the above noted as well as other defects and objections in the provision of a.

. mop or devices of similar character wherein the fabric may be readily and easily removed from or mounted on the head of the device without the necessity of actuating or manipucharacter and nature wherein the parts formed of metal or other relatively hard material are effectively shielded by the fabric from contact with objects when the device is properly used.

While some of the more salient features, characteristics and advantages of a device embodying this invention have been above pointed out, others will become apparent from the following disclosures.

The invention includes these and other features of construction and combinations of parts hereinafter described, and shown in a preferred form in the drawings, and more particularly indicated by the claims.

On the drawings:

Fi' ure 8 is a bottom plan view similar to Figures 3 and 6 showing a still different form of the device.

Figure 9 is a fragmentary vertical sectional view in upright position taken substantially as indicated by the line IX-IX of Figure 8.

As shown on the drawirigs: J

As seen more clearly in igures 1 to 5 inelusive, the structure selected to illustrate an embodiment'wof the present invention includes a mop head generally indicated by. the reference numeral 1, which head includes a substantially flat body portion 2 having an upwardly extending central rib 3 therein which is slotted at the rear portion thereof as indicated at 4. A handle socket 5, preferably pressed from a single piece of metal, is

1 pivoted in the slotted portion 4 in any other desiredf%manner or as shown by a rivet 6.

In this instance the body portion 2 is pro vided {with an upwardly turned peripheral flange which is provided with an arcuate outwardly turned rim 8 for a purpose that will later appear. Adjacent the flange 7 the body 2 is provided with a peripherally extending groove 9 for containing any desired a rivet 13. The strip 11 extends outwardly beyond the body portion 2 at the rear thereof, and is bent 1n opposite direction to form a pair of resilient arms 14 and 15 which substantially follow the peripheral contour of the body 2 although these arms are in spaced relationship with the said body. The arms 14 and 15 each preferably terminate before reaching the most forward portion of the body 2 thereby leaving a gap between the ends of the arms to permit the free attachment thereto of a mop fabric or similar element 16 having a tubular binder 17 thereon.

As seen more clearly in Figure 1, one end of the tubular binder 17 is slipped over the arm 14 and pushed therealong-until the end of the binder reaches a position adjacent the handle socket 5, when the opposite end of the binder 17 is slipped over the arm15 in similar manner. The resiliency of the arms 14 and 15 force the flexible binder 17 into intimate contact with the flange 7 and outwardly turned rim 8 thereon, to thereby produce a grippin action which positively holds thefabric on t e head while the device is in use.

' it is simply necessary to slip the binder 17 To remove the fabric from the head the body portion '2 to permit the carrying of a relativel large quantity of fluid, this quantity not being limited by the capacity of the groove 9. a

In Figures 6 and 7 there issliown a mop head of slightly different form than the one disclosed in Flgures 1 to 6inclusive. This mop head includes a substantially flat body portion 18 having a depending peripheral flange 19 which is also provided with an outwardly turned rim 20. In this instance, a strip 21, preferably of metal, is bent substantially upon itself adjacent the mid-portion thereof as at 22 and positioned adjacent the underside of an aperture 23 in the rear portion of the body 18 where it is secured 1n any desired manner or as shown by a rivet 24 to a handle socket 5, similar to that shown in connection with Figures 1 to 6 inclusive, the rivet acting as a pivot for the said socket. In this form of the present invention, however, the strip 21 is bent in opposite direc tions and made to follow the inner contour of the rear ortion of the flange 19 to which it is secured by a plurality of rivets 25, before it again diverges so as to form resilient arms 26 and 27 which substantially follow the peripheral contour of the body portion 18 although in spaced relationship thereto. A suitable fabric may be secured to the arms 26 and 27 in the same manner as previously described herein with regard to Figure 1. The strip 21 in this instance however aids in providing a more rigid head byl bracing and stiffening the rear portion of t e flange 19.

In Figures 8 and 9 there is shown another slightly different form of mop head including a body portion 28 which is indented or recessed as at 29 in the top thereof to accommodate a ca plate 30, secured to the body 28 by means 0 lugs 31 passing through suitable apertures in the body. The cap plate is apertured as at 32, and adjacent each side of the aperture is provided with a raised portion 33 to act as a bearing for a pivotal handle socket 3 1 having a rolled end 35 seating in each of the ortions 33. The handle socket is also provi ed with an angularly disposed tongue 36 which presses against the body portion 28 when the handle socket is pivoted, whereby the resiliency of the body portion 28 retains the handle socket in its desired position.

The body portion 28 has a downwardly turned peripheral flange 37 provided with an arcuate outwardly turned rim 38 thereon as in the previous forms. In this instance the head is rendered exceedingly rigid by a strip 40,

referably of metal, which is bent so as to ollow the inner peripheral contour of the flange 37 to which it is secured by rivets 41 or in any desired manner, the strip passing out througha suitable notch in the rear portion .of the flange 37 and then bending in opposite directions to form resilient arms 42 and 43 which function in the same manner as the arms described hereinabove.

Although in each instance in the drawings the device is disclosed as being triangular in shape, this shape being desirable in that the outward apex of the triangle may be used to reach places difiicult of access and because the contour of a triangle aids in keeping the mop fabric secured to the head, yet it is to be understood that the head may be of any desired shape. It is obvious too that the resilient arms need not of necessity'be formed of a single strip of material and may function as well if formed of a plurality of pieces, but the single strip is desirable for the added resiliency imparted to the arms thereby and for the purpose of economy.

From the foregoing it is apparent that I have rovided a mop of similar device incorporating a head which is capable of carrying liquid in such a manner that the same will drip through upon mop fabric, and to which the mop fabric may be secured or from which i it may be removed without the actuation or manipulation of extraneous mechanical parts. It will also be apparent that the present invention is simple in construction, very durable. and may be economically manufactured.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this inven tion, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art and defined by the appended claims.

I claim as my invention:

1. In a device of the character described, a head including a body portion having a flange therearound, an outwardly turned rim on said flange, resilient means extending partially around said body portion, and a fabric having a tubular binder thereon slidable over said means so as to be pressed thereby into engagement with said rim.

2. In a device of the character described, a head including a body portion having a groove therein with apertures at the bottom of said groove, a pair of resilient arms extending one in each direction partially around said body portion in spaced relationship thereto, and a mop fabric having a tubular binder slidable over said arms to be gripped by said arms and said body portion with said fabric underlying the apertures in said groove.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County,

Illinois.

PETER BROWN.
