v MOP GLAMPING DEVICE Filed Deo. 28, 1945 ATTORNEY Patented Aug. 19, 1947 narran stares anni (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) This invention relates to mops and more Darticularly to a clamping device for the handles thereof.

It is an object of this invention to provide a clamping device for a mop handle that provides a positive, unyielding, gripping action upon the mop cloths.

It is a further object of the invention to provide a device of this character that is composed of a relatively Yfew, simple and inexpensive parts, of rugged construction, easily manipulated to open or closed position, readily assembled and ineXpensively manufactured.

With the above and other objects and features in View, the invention will now be described with reference to the accompanying drawings which illustrate a preferred embodiment f the invention and will be pointed out in the claim.

In the drawings:

Fig. 1 is a front view of the improved mop clamp in open position;

Fig. 2 is a View similar to Fig. 1, but with the clamping bar in closed or holding position;

Fig. 3 is a cross sectional elevation taken along the lines III- III of Fig. 1;

Fig. 4 is a sectional plan view taken along the line IV-IV of Fig. 1;

Fig. 5 is a detailed sectional plan View taken along the line V-V of Fig. 1;

Fig. 6 is a detailed sectional elevation of the clamping bar taken along the line VI--VI of Fig. 2; and

Fig. 'l is a detailed sectional view taken along the line VII-VII of Fig. 2 showing the engagement of the clamping bar with the bail member of the mop.

The mop handle is indicated at I0. A bail II of heavy gauge wire stock, bent in a substantially triangular form, is secured to the lower end of the handle I0. The opposite sides of the lower end of the handle are channeled as at I2 to a depth that is just sufficient to receive the upper, oppostely disposed, ends I4 of the bail II, recesses I6 in the upper ends of the channel I2 being provided to snugly receive inturned projections I8 formed on the ends I4, The ends I4 are preferably formed on the bail in such manner that normally they tend to flare outwardly. Hence, when the ends are forced inwardly and a sleeve 2i) encircling the handle I0 is slid downwardly over the ends as shown in Figs. 1 and 2, the ends are rigidly socketed in the channels I2 and recesses It and thus the bail is securely but detachably mounted on the handle.

A pair of guide plates 22 are mounted on the opposite sides ofthe angular section of the ybail I I, matching, semi-circular crimps 2t (Fig. 4) being provided along the outer edges to embrace the stock ofv the bail. The Plates 22 may be permanently secured in position as by riveting or spot Welding as indicated at 26. The upper ends of the plates are reduced in width to form a tongue 28 that is snugly received in a transversely disposed slot 30 provided in the lower end of the handle Ill. The lower ends of the plates 22 are provided with flanges 32 that serve as a bearing for a purpose to be later described.

The clamping bar of the mop is generally indicated at 33. This bar is comprised of two elongated Strips of sheet metal material 34 and 3S. The strips are complementarily bent outwardly along their outer edges to form a channel 38 for receiving the vertical sides @Il and a cross bar 42 of the bail Il. The bar 33 is arranged to be adjusted with respect to the bail Il by means of a threaded stud llt. The lower end of the stud 44 is reduced as shown in Fig. 6 and has an opening it provided centrally thereof.

The bar 33 is secured to the lower end of the stud 4t by swaging the stock of the strips 3Q and 36 inwardly into the opening 4G as clearly shown in Fig. 6. It will be understood that other means for securing the bar to the stud may be employed such as by riveting, welding or otherwise. The plates 3Q and 36 are held securely together in mounted position as shown in Figs, 1 and 2 by spot welding or riveting as at d8. The upper end of the stud Q4 is guided for vertical movement in a channel formed centrally of the plates 22 by complementary, semi-circular, rounds 52 struck outwardly from the body portion of the plates 22. This channel 50 is preferably made of such a diameter that a slight frictional engagement is afforded between the inner surface of the channel and the threads of the stud dit so that the stud and the clamping bar 33 will be frictionally maintained in any position to which they may be moved upwardly and downwardly with respect to the bail I I.

A knurled or Wing nut 5d is threaded upon stud il and bears against the flanges 32 which serve as a seat for the nut. Upon rotation of the nut in one direction, the stud d@ and clamping bar i3 are positively screwed downwardly from the open position shown in Fig. 1 to the closed position shown in Fig. 2. In such closed positions, it is obvious that any rags or cloths which have been inserted between the clamping bar 33 and the cross bar 42 of the bail II will be held positively in locked position between these elements.

It is noted that the wing nut 54 and the general construction and assembly just described is such that all of the movable parts lie within the connes of a vertical plane dened by the outer edges of the sleeve 20. Hence, itfollows that there are no projecting parts that might interfere with the use of the mop around molding boards or the legs of the furniture and the like. It is also noted that the nut and threaded stud clamp operating means provides a Very simple and eiective device for clamping the mopping material on the bail, that the parts are rugged, durable, reliably operative and not susceptible to getting out of order.

The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalty thereon or therefor.

Having described the invention what is claimed as novel and desired to be protected by Letters Patent of the United States is:

In a mop construction, a handle, a bail of substantially triangular shape formed of heavy gauge Wire having a transverse bar and having straight parallel Yupper ends and an inturned projection extending from each of said ends, means for securing said handle to said bail comprising, channels on opposite sides of said handle adapted to receive said straight parallel ends of 'said bail, recesses at the ends of said grooves being adapted to receive said inturned projections. of said bail, and a smooth cylindrical sleeve encircling said handle whereby said bail is rigidly socketed to said handle; two guide plates of irregular octagonal shape rigidly mounted on opposite sides of said bail, three sides of said octagonal plates dening a tongue, a transverse slot in said handle adapted to frictionally receive said tongue, a channel formed in the central body portion of said plates by complementary semi-circular rounds being struck outwardly; a cross-bar slidably mounted on said bail and engageable with said transverse bar thereof, a threaded stud connected to said cross-bar and extending into said channel, a ange at the lower end of said channel, a nut on said stud for adjustably moving said stud and cross-bar, said flange acting as a seat for said nut, said channel frictionally and slidably engaging said stud to maintain said crossbar in any position to which it may be moved when out of engagement with said transverse bar of said bail.
