SCRUBBlNG-BRUSH.

SPECIFICATION forming part of Letters Patent N0. 728,837, dated May 26, 1903.

Application filed August 9, 1902. Serial No. 119,057. (No model.)

To all whom it may concern.-

Be it known that I, JAMES BEEBY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Scrubbing-Brushes, of which the following is a specification. I

My invention has relation to new and useful improvements in scrubbing-brushes; and the object of the invention is to provide a brush of the character mentioned with a sim-' ple and improved means whereby it may be attached to and used in connection with a mop-head of Well-known construction.

The invention consists in providing the back or upper face of a scrubbing-brush with a clamping or holding device adaptedto be engaged and held by the jaws of a mop-head, and particularly mop-heads provided with a fixed jaw against which a movable jaw of a bridle form engages.

I have fully and clearly illustrated my invention in the accompanying drawings, wherein Figure l is a perspective view showing a brush provided with my improved attachment and clamped to a mop-head. Fig. 2 is a view in side elevation, partly in section. Fig. 3 is a perspective view of the holding device. device.

Referring to the drawings, 1 designates a mop handle or stick of such form and length as may be desired or required by the uses to which it may be subjected. At its lower end this handle is formed with a reduced portion 2, providing a shoulder 3, substantially as shown in Fig. 2 of the drawings.

Upon the reduced portion above mentioned is secured the fixed jaw of the mop-head. This fixed jaw consists of a ferrule or socketpiece 4, which fits over the lower end of the reduced portion and is secured thereto in any suitable manner, as by a fastening-screw 5. Projecting laterally from the socket-piece are oppositely-directed arms or members 6, arranged in longitudinal alinement with each other and constituting the fixed jaw of the mop-head. The alining outer faces of these jaw members are formed with a longitudinal groove or channel 7, extending for the entire Fig. 4 is an end view of the holding length of the said members and terminating at its respective ends in recesses 8, formed in the outer ends of the fixed jaw. At a point intermediate its ends the fixed jaw is provided with a recess 8 which extends upwardly into the body of the socket-piece.

Encircling the mop handle or stick 1 is a ring or collar 9, adapted and arranged to slide longitudinally of the said mop-handle and which is formed with an interior annular flange 10, adapted to abut the shoulder 3,

and thereby limit the upward movement of the collar.

11 designates a bifurcated hand-lever arranged to straddle the mop-handle and the legs 12 of which are pivotally supported upon the ring or collar 9 at diametrically opposite points thereon.

13 designates a movable clamping jaw or bridle comprising a transverse portion which lies normally parallel with the face of the fixed jaw and'is provided with rearwardlyextending arms or members 14, which converge toward each other and the rear ends of arranged an expansive spiral spring 15, the

respective ends of which abut the ferrule 4 and the sliding ring 9 and the expansive tendency of which serves to force the collar 9 away from the fixed jaw and hold the .lever depressed against the mop-stick, whereby the movable jaw is held in positive engagement with the fixed jaw.

In the foregoing I have described a Wellknown form of mop-head with which myimproved brush is adapted to be used; but it is obvious that the brush may be used in connection with any common form of mop-head in which are employed a fixed and a movable jaw of the character mentioned.

16 designates the back of a brush, which 5 may be of any approved form and to the upper portion of which my improved holding device is attached. This holding device consists of an elongated plate or strip 17, ex-

tending longitudinally of the back of the loo brush and provided with ears or extensions 18, formed with apertures 19, by which the said plate may be secured to the back of the brush by any suitable or desirable means.

Extending for the greater portion of the length of the plate 16 is a forwardly-curved flange 20, the outer curved surface of which conforms to the shape of the groove or channel in the fixed jaw. This flange 20 extends forwardly for a sufficient distance to permit its edge to terminate at a point far enough from the plate to provide a longitudinal slit or opening 21, which opens into a recess formed between the flange and the body of the plate. The opening 21 is of such width as to per mit the ready entrance of the movable jaw of the mop-head to the interior of the holding device.

At a point intermediate the ends of the curved flange is provided a rearwardly-extending projection 22, which is adapted to be seated 'in the recess 8 in the fixed jaw of the mop-head, and thereby assist in providing a rigid connection when the brush is held by the mop-head. This projection is arranged atsuch an angle that when inserted in the recess in the fixed jaw the brush and handle will be disposed at a proper angle with relation to each other.

When it is desired to attach the brush to the mop-head, the movable jaw of the mophead is inserted or hooked under the flange 19. The lever 11 is then swung on its fulcrum to bring the mop-jaws into closed relation, whereby the projection 21 will be drawn into the recess 8 in the mop-head, and the curved flange 19 will be securely clamped within the channel in the fixed jaw and the brush thereby gripped and rigidly held by the mop-head.

. Having thus fully described the invention, what is claimed as new is- 1. In a device of the character described, the combination with a mop-head comprising a fixed jaw having a recess therein, a movable jaw and means to lock the jaws together, of a brush having a projection to be seated in the recess in the fixed jaw, and means on the brush engaged by the movable jaw and thereby held in engagement with the fixed jaw to lock the brush to the mop-head.

2. In a device of the character described, the combination with a mop-head comprising a fixed jaw having a recess therein, a movable jaw, and means to lock the jaws together, of a brush having a flange thereon adapted to be, clamped between the mop-jaws, and a projection arranged to be seated in the recess in the fixed jaw when the flange is locked between the jaws.

3. An attachment a securing-plate, a flange on the plate, and a projection on the flange.

4. An attachment for brushes, comprising a securing-plate, a forwardly-curved flange on the plate, and a rearwardly-extending projection on the flange In testimony whereof I affix my signature in presence of two witnesses.
