Application filed September 19, A1924. SeriallNo. 738,561.

y Thisv invention relates to 'a mop andzan improved method of making a mop which maybe produced cheaply and inexpensively. l

Itis an object of this invention to provide' Ala mop head adapted to supportthemop fabric and provided with a quick attaching Vand detaching means. l Y

. It is also an ob'ect of this invention to `provide a mop head adapted to support the mop fabric in proper extended relation and having means for conforming with the changes lin the size of the inop fabric due to'either stretching or shrinkage.

Itis a further object ofV this invention to provide a mop which may be inexpensively vmade and which is provided with a simple yand inexpensive means for attachingand deltaching the mop fabric.

yIt is a further object of this invention to' '20 vprovide a mop head which is stamped out of a single piece ef sheet metal to formthe top and sides of the head.`

It is a further object of ythis inventionto provide a'rnea'ns for making a mop of this V classin which the top and si'desof the head are formed fromasingle sheet of metal,v the sides ,being shaped at the ends to form means for frictionally engaging the mop fabric, and in whichy the means 4`for attaching and detachingl the fabric is eective notwithstanding the fact that there may be arelatively wide range offvariation in size of the mop fabric.

Other and furtherl importantobjects of this invention will be apparentl froml the .disclosures inthe specification land the companying drawings.y

The invention (in a ypreferred form) is l illustrated in the drawings and hereinafter 4.0 more fullydes'cribed. n

As shown-on the drawings: A y. vThe mop headcomprises `,a single sheet of ymetal whic'hnis bent down on either side to form a top?, and vsides 1 and 2, Each ofthe sides 1 and k.2 viSv-stamped into the'form-of a longitudinal groove as shown in Figure?) to-receive a mop fabric 5 which is of the type v shown for example in my prior Patent No. 1,254,776. Afsuitable ksocket'fi is rivetedl or otherwise suitably securedto-the top 3.. The handle is secured in thefsocket 3 bya pin ll2 rigidly secured through thesocket. End edges 6 ofthe sides land 2 are deflected Youtvvardlyand act to frictionally engage the mop fabric 5 to maintain the latter rinly and -in extended .relation in the vgrooves of ,the sidesfl `and 2. f As shownin ,Figure 7 the i ends` of the sideslandr2 are cut-,along the junctionwith the top 3 .to form flexible ltongues l'which are'bent inwardly sothat :they V`act r-as braces 4tending. to l resist inward pressure -onthe sides oftheniop head and also act to keep a tensionon the mop fabric. Outwardlyf'struek tangs 14EV in the `sides assist in frictionally bindingthe, fabric. As shown. in Figure 4g. thev attaching anda detaching j means consistsrpreferably of a bolt 'Zwhich extends through the fabricy the sides l and 2 and a .clamping strip 9'intoa position betweenthe adjacent -ends .of the'mop fabric. The mop fabric isV securelyheld in position by meansv of a clamping strip 9.,apertured to l `receive the bolt and .said strip extends on C either side ofthe Y.bolt into the kchannel 11 Yeo of the fabric 5 and frictionally and securely :means of a v'wing nuty or other suitable means 8. Y y v n `Although it is not absolutely necessary,-it is frequentlyY desirable to reinovethe mop fabric ofvthi'sftype fromthe mop head so p that the `mop fabric may be washed, cleaned or renewed. It will be apparent from the structure disclosed that the use of the clamp ing strip 9 makes it possible to' accommodate and use mop fabrics which may vary` in length through a relatively wide range. In other words, when the mop snew, the fabric will be stretched tightly to a point where the ends are fairly closely adjacentI the projecting end of the bolt 7, and as time i goes on, if there is any` shrinkage in washing, the mop fabric may still be used eifec- Vtively owing to the fact that the engaging and clamping prongs 10 are somewhat remote from the boltB. On the other hand, in theevent the fabric should stretch instead of shrink, the clamping means I have provided is equally of value in that the excess maybe threaded over the'ends of the clamping strip and compressed suiliciently to permit the fabric to be firmly secured in posi-V tion as described.

.It is obvious that this mop may becheaply j and inexpensively made `diie to the fact that the head is formed of a single sheetof metal and that since the sides" are fashioned as shown forming a clamping means, the additional clamping means, is enabled to be less elaborate.H i j I am' aware that many changes may be made, andnumerous details of construction @may be' varied through a wide range `without `being `spaced and provided with means "adapted to penetrate `the mop fabric, ai mop fabric stretched around the grooved portion of the sides, `and alclamping means located between said spaced ends comprising a bolt projecting through said fabric and said gro'oved sides, saidbolt being provided with a. clamping `element on its free end and adapted to secure the mop fabric' in operaj tive positionto said head.

being spaced and provided with means adapted to penetrate the mop fabric, a mop fabricV stretched around-the grooved portion of the sides, and a clamping means located between said spaced ends comprising a bolt'projecting through said fabric and said grooved sides and a strip with pronged ends `associated with said bolt adapted to secure the mop fabric inits operative `position tosaid head. j p

4.` A'mop comprising a sheet metal head,

having integral groovedsides provided with pronged end edges, a handle socketsecured 4to said head and clamping means comprising a holt and a strip secured by said bolt and adapted to "cooperate withua side of thehead to frictionally clamp the ends of'a mop fabric on said head when said fabric is stretched around said `head within said grooved sides. j i i 5.-A mop comprising a `mop head having sides depending therefrom, a mopwfabrio stretched around said head on said sides,

and a clamping means comprising a bolt extending through said fabric and the sides of said head and a strip carried by said bolt, said strip having deflected edges adapted to BIS` frictionally engage theends of saidfabric Y Vfor clamping the fabric to said head.

6. A mop comprisinga mophead having a top and a pair of grooved sides, the end portions of said sides terminating in spring tongues projecting inwardly beneath the top forresisting inward pressure andhaving noV the end edges deected `outwardly from the i periphery of saidtop, the ends of said head between said sides remaining opema mop `fabric `stretched around said head within the grooved sides thereof, clampingn means `comprising a bolt extending through said ,fabric` and the sides of saidheadgand a strip carried bysaidbolthaving deflected edges adapted to frictionally engage the ends of saidfabric for said head.
