LPOLSHING Its/IOP.

Application led May 26,

T0 all @07mm t may concern.'

Be it known that l, Hnnnnnr M. STURGrs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of liissouri, have invented certain new and useful Improvements in Polishing Mops; and l do declare the following to be a full, clear, and exact description `of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of reference marked'y thereon, which form a part of this specification.

This invention relates to polishing mops and particularly to mops for cleaning and polishing floors and walls.

The invention contemplates a novel construction ofV mop head as well as novel mea-ns for fastening the mop head to the mop stick. The applicationof the invention as well as the novel details of construction will be apparent by reference to the following ,description in connection with the accompanying' drawings, in which Fig. 1 is a perspective view of a complete mop constructed in accordance with my invention.V

Fig. 2 is a disassociated view of a por tion of the mop stick and the mop head, the 'securing collar for attaching the mop head rod to the handle being` Shown partly in section. I

Fig. 3 is a sectional view on of Fig. 2, and

Fig. l is a sectional view on the line 4 4 of Fig. 2. l v

The mop head is shown as consisting, of a substantiallyl heart-shaped member consisting of two tele'scoping parts or flanged

plates

1 and 2. The topplate 1 yisl provided with a depending peripheral flange 3, having an offset or shoulder portion 4l to form a groove into which may be received the turned-over end 5 of the upstanding flange 6 integral with the lower plate 2. The turningover of the flange 6 provides a fastening means whereby the two

Vplates

1 and 2 may be securedv together and the two telescoping`

fian'ges

3 and 6 constitute a rigid support and 'spacing means for the two the line 343 plates, thus lproviding notlonly strengthrbut the desired thickness of the head to receive the enveloping mop Vcloth or Sack 7 which 1922. Serial No. 563,775.

,may be of any appropriate construction adapted to fit over the mop cloth-receiving member consistingof the plates-1 and 2.

It will be observed by reference to Fig; 2 that at the wider portion of the mop clothreceiving member there is a slot 8forrned by bisecting the two plates to leave a space for the hinged mop head rod 9 as wellas to vprovide a space to receive the knot formed by the strings 10 for fastening theimopcloth to the head, it being understood that these enveloping` cloths are generallytied tothe mop-head and some means should be provided for taking care of thevends of the f' strings so in the present construction they may readily lie within the slot 8.

The central portions of the plates land 2 are pressed in to form contacting web portions 11 and 12 and throughl these contacting portions I propose toffasten rivets orother Suitable fastening means designated 13 Aand 14 in Fig. 2 so that the centers'ofv the plates face of whichis curved to conformfto the*y curvature ofthe head 20, as will be clearly seen in Fig. 2- so that the mop head consist-v ing of the

plates

1 and 2 may be held-at any angle with respect to the rod 9 and from the drawings it will be apparent that the angle of the head with respect t0- the rody 9 can be readily changed by applying the mop cloth to the floor or the head to the-floor and tilting the rod 9 to the desired angle.

The'construction thus far described, except for the mopV cloth, is preferably entirely of metal, which maybe struck up by suitable dies and, therefore, conveniently and inexpensively manufactured.

Means is also provided` for v fastening the end of the rod 9 to the mop 4stick and by reference to Fig.v 2 it will vbe observed that the rod 9 contains a threaded head 24 adapted to be engaged by the threaded collar 25 carried by the end of the socket member 26, fastened to the mop stick 2"? by the ferrule 28 in an appropriate manner.

The socket member is provided with a slot 29 to receive the lug or projection 30 on the eXtreme end of the rod 9. `When it is desired to connect the mop stick to the rod 9, the lug or projection 30 is introduced into the slot 29 of the socket member 26 and the collar 25 is turned on the threads 24C of the rod 9 to draw the lug 30 into the socket so that there can be no relative turning movement between the mop stick 27 and the rod 9, the collar 25 effecting the tight connection between the rod 9 and the stick 27.

When the parts are assembled as shown in Fig. l, the device will be complete and it will be apparent that the mop head can be turned at any practical angle and held there due to the frictional contact between the bolt or shoe 23 and the end of the head 20. The mop head consisting of the plates l and 2 presents a broad flat contacting surface against which the mop cloth will bear to permit an eflicient contact in passing over the floor or walls and the point 3l of the head affords a convenient means whereby access may be had to corners so that the mop may be passed into the corners or recesses to permit the mop cloth or fabric to take up the dust and polish the surface.

Attention is called to the fact that the lug 30 is slightly tapered as is also the slot or recess 29 of the-socket member 26. Therefore, when the screw collar or nut 25 is turned, the lug will be drawn into the socket until it seats tightly against the wall of the recess 29 to make a rigid connection between the bar 9 and the socket member and, consequently, the stick, since the socket member is rigid with the stick, being held thereto by the ferrule 28. This arrangement prevents any lost motion or play between the rod 9 and the stick and also eliminates liability of the threaded connections working loose on account of relative play between the rod 9 and the socket member.

It is understood, of course, that the envelope surrounding the mop head conforms generically to the shape of the head and that the fibers are connected to the envelope in the usual way.

The device is susceptible of modifications without departing from the general scheme of the invention and I, therefore, do not wish to be limited in all aspects of the invention to the precise construction shown.

What l claim and desire to secure by Letters Patent is:

l. A mop head comprising two flanged plates telescoped together and having the edge of the iiange of one plate bent over the end of the complementary plate to provide a hollow fiat head, the two pla-tes having portions struck out therefrom to provide bearings, a rod support mounted in the bearings, a rod on the support having an enlarged head through which the support projects, and a spring-pressed bolt in recesses in the plates for frictionalcontact with the enlarged portion of the rod to maintain angular adjustment between the rod and the head consisting of theA two plates.

2. A mop head comprising a hollow, heart-shaped member having a slot at its widest end, a rod pivoted to the heartshaped member and having swinging movement through the slotted portion of the member, and a spring-pressed friction device bearing against the rod to maintain angular adjustment between the heartshaped member and the rod.

3. A mop head comprising a mop clothreceiving member consisting of a flat member having a slot at one end, a rod pivotally connected to the flat member and having swinging movement through the slot, and a friction device carried by the member and bearing against the pivoted end of the rod to maintain angular adjustment with respect to the rod and the member.

4. A mop head comprising two spaced plates having peripheral flanges at right angles to the plates, the flange of one plate being in telescopic connection with the flange of the other plate, the flange of one plate being bent over the edge of the other plate to provide a fastening means between the two plates, the central portions of the plates having portions offset with their respective plates so that the central portions of the two plates abut oner against the other, means riveting the two abutting portions together, the abutting portions also having bearing portions struck up therefrom, a pintle in the aligning bearing portions, and a rod carried by the pintle, the rod having means for attachment to a mop stick.

5. A mop head comprising two spaced plates having peripheral flanges at right angles to the plates, the flange of one plate being in telescopic connection with the flange of the other plate, the flange of one plate being bent over the edge of the other plate to provide a fastening means between the two plates, the central portions of the plates having portions offset with their respective plates vso that the central portions of the two plates abut one against the other, means riveting the two abutting portions together. the abutting portions also having aligned bearing portions struck up therefrom, a pintle in the bearing portions, a rod carried by the pintle, the rod having means for attachment to a mop stick, and a friction device guided by the abutting portions for engagement with the end of the rod to maintain angular relationship between the rod and the plates.

6. A mop head comprising-two substantially heart-shaped plates having edge flanges, the flange of one plate being telescoped within the flange of the other plate, the outer flange having a bent-over edge to engage the top of the complementary plate to secure the two plates together, and means for fastening the mop stick to the plates.
