Application led September 27, 1911-. Serial No. 651,479.

To all whom 'it may concern:

Be it known that I, FERDINAND R.W0LTER,

a citizen of the United States, residing at' Minneapolis, in the county of Hennepin and i o State of Minnesota, have invented certain new and useful Improvements in Mop- Holders; and I do hereby declare the following to be a full, clear, and exact descrlptlon of the invention, such as will enable others skilled in the art tol which it- Aap'pertains to make and use the same.

My invention has for its object to provide an improved mop-head, the term mop-head being. used -in a broad sense to -include de# vices adapted to hold mop rags, floorand window Scrapers, andthe like. l

Generally stated, the invention conslsts of the novel devices and combinations of d evices hereinafter described and defined 1n the claims.

In the\ accompanying drawings whlch illustrate the invention in its preferred form, like characters indicate .like parts throughout the several views. u

Referring to the drawings, Figure 1 1s a plan view of the improved mop-head, wlth some parts broken away, and some. arts sectioned; Fig. 2 is a side elevation o the parts shown in Fig. 1, some portions being broken away; Fig. 3 is a fragmentary view partly in-plan and partly in. section on the line fr ma of Fig. 2; Fig. 4 is a detail in elevation, with parts broken away showing the relatively movable clamping bar of the mophead; Fig. 5 is a detail in transverse section taken on the line :v5 of Fig. 1 and Fig. 6 is a transverse section taken on the line ai w? of Fig. 1. I

The numeral 1 indicates a pole, to one end of which a cast socket-or cap 2 is rigidly secured in any suitable way. The soc et 2 is provided with a fork made up, preferably, of a pair of stiff metal rods 3, the converging ends of which'are cast, or otherwise rigidly secured in one end of the said socket 2, and the outer ends of which are bent inward or toward each other to form hook-like .projections to fingers 4.

The mop cloth or scraper blade is adapted to be clamped and held between relatively fixed and relatively movable clamping bars 5 and 6, respectively, both of which, as shown, are channel-shaped in cross section, the channel of the bar 6 being large enough to receive the channel bar 5. The channel bar 5 is preferably a stamped metal piece cloth or rag of bul provided in its channel near its ends with depressions or bulged seats 7 which are normally engaged by the hook ends 4 of the fork rods 3. This affords one extremely simple and eicient way of detachably connecting the bar 5 to the fork rods 3. The importance of thisdetachable feature will be later noted.

The relatively movable clamping bar 6 is preferably-a cast part having a centrally located stem portion 8cast integrally therewith, and formed with diametrically opposite longitudinally extended ribs ,9. This stem 8 is guided by, and movable endwise, in a guide tube 10, the other en d of which is rigidly seated in the cap. 2, being preferably cast therein. This guide tube 10 is provided with long diametrlcally opposite longitudinally extended slotsl 10l in which the ribs 9 of the stem 8 are arranged to work.` In its extreme end, the said stem 8 is provided with a depression 8 .that is engaged by an approximately spherical head 11 of a clamping lever 12 and which lever has a curved cam acting section 12 that Work's through es i' the slots 10" and bears also against the round head of a plunger- 13. This plunger 13 affordsl a yielding abutment against which the said lever acts, and it is spring-pressed by a quite strong coiled spring 14 seated in the guide tube 10, and re-acts against the cap 2. As the head 11 is wider than the slots 10, it affords a sliding pivotal connection between the said lever and the tube 10, which prevents the lever from being accidentally disconnected from the tube. As the head 11 rest-s in the depression 8 of the stem8, and this, in turn, bears against the wallsof the guide tube 10, italords additional su port or the head 11 so that these parts will readily wear. out. By the construction employed, it obviates the necessity of weakenlng the tube 10 by any bolt or rivet holes,

and renders the clamping' lever 12 readily` not when the mop-head is used to clamp a mop form, and which cannot be easily applic between the clamping bars of an ordinary mop-head, or easily re- .moved therefrom. vWith this barf madel de'- tachable, any lknd of a bulky rag or mopl 'cloth may be easily applied between the cooperating clamp bars, or removed from ,be-v tweenthe same when the-said bar 5'is detached from` the rods 3. When such mop' cloth Yor rag is` placed 'between the two clamping bars 5 and 6, the former maybe quickly and easily ap lied in working position, or detached. therwise stated, 'the feature of making the relatively fixed bar 5 removable is,l however, of 'greatest importance because of the easy and ready means it. affords for putting in and removing the mop 'cloth or rag (especially the latter fprocound less) fromthemo -head. It has been in practice, that t e fabric, suchas is being used for this purpose, after continued use, will become badly soiled andl tangled up'so that the removal from thefmop-head is 'rendered a very tedious and unpleasant tas k or operation. l

` When the clamping lever 12is turned into the position indicated lby dotted lines in Fig. 1, the relatively movable clamp bar 6' may be retracted from the bar 5, as indicated 4 by dotted lines in said view. When, however, the said lever is turned into the position indicated by vfull lines in said Fig). 1, the two clamping bars 4willv be tig tly pressed toward each' other and will be caused totightly pinch and hold the mop cloth. The yielding abutment 13, when or blades for cleaning oors, or in connection with smaller scraper blades Vor-other v cleaning devices for cleaning windows.

In actual practice, the device has been found highly efficient, very convenient, and easily operated.' Furthermore, it `may be constructed at comparatively small cost.

What I claim is: f

1. A mop-head comprising a member hav- .said detachable Y clamping bar.

ing diverglng prongs, Aa clamping bar havt ing degat-.btie "elgagemnt with' the'A said prongs a,` relatively movable clamping bar, and means for pressing the latter toward the 2.` A mop-head comprising a member. having projecting prongs, a clamping bar detachably engageable with the oset ends of said prongs, wrelatively movable clamping bar, and means for ressing' the latter toward the said detacha le clamping bar.

3.111 a mop-head, the combination'with a member having diverging prongs and a central guide tube,- of a pair of. coperating clamping bars,- one removably connected to 'said prongs. and theother yslidably mounted on sald guide tube, a'cam lever slidably pivotedto said guide tube and operative on one of thel` said: clamping bars, and a yielding abutment against which the said cam lever is arranged to act, substantially as described.

5. In a-mo Y, thecombination with a member having iverging prongs andA a central guide tube projecting therefrom, said prongshaving inwardly bent hook-like ends, and said. guidetube l opposite longitudinally-,extended fslots fof a channel-shaped clampingl bar engageableat aving diametrically its ends with. inwardly turnedl ends of said s prongs, a relatively movableclamping bar having a stem working in said guide tube and having ribs working in the slots thereof, and a sprmg-pressed cam lever workmgm the slots .of said guide tube and operative on. the stem of said relatively; [movable clamping bar, substantially as described.
