nor-FRAME.

i To all whom it may concern:

Be it known that I, EDMOND PHILnMoN BEAUDET, a subject of the King of Great Britain, and resident of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Mop-Fra1nes, and do hereby declare the following to be a full, clear, and exact description of same. g

This inventionrelates to a frame adapted to have a mop fabric attached thereto and to be manipulated preferably through, the medium of a long handlefor the washing and dusting or general cleaning of floors, walls, windows and the like. The invention 'appertains particularly to a frame comprising pivoted sections heldby a latchfdevice in a position maintaining the fabric in a substantially flat, stretched-out position, such latch device being operative to release the frame and permit of the folding or collapsing of same to loosen the fabric so that it may be thoroughly shaken -or squeezed out to remove foreign matter therev25 from. I 1 p An object'of the present invention is to facilitate the manufacture of mop frames of the abovespecified type and to economize in such manufacture by the employ-' ment of simply contructed members adapted to be readily assembled in a cooperative arrangement devised to reduce thenumber of parts heretofore used andto promote a morecomplete folding of the frame sections.

further objects as ddescribed and particularly pointed out in the accompanying claims. For full comprehension, however, of my invention reference should be' had to i the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same-parts and wherein: w l p Figure 1 isla'plan view of my improved mop frame;

Fig. 2 is asideelevation of folded? position; and a I l Fig. 4 being an enlarged detail-side elevathe frame in Fig. 3 is a transverse section. on line Specification of Letters Patent. Patented une 29, 1920. Application filed September 16, 1919. Serial No. 324,229. i if I away, to illustrate the engagement of the latch plate with the frame.

As shown in the drawings my improved frame includesisections 2 and 3 bent into U-form and overlapped at theiropen inner ends where they are pivotally connected to swlng toward each otherthrough the mesections. The pivotal sections are preferably made from stripsoffmetal plate and present openings 5 in the opposite sides thereof near their outer ends for the rej ception of removable pins 6 by means of which a mop fabric 7 is attached to the frame. The fabric is located beneath the frame and has its ends carried upwardly and inwardly over the frame ends, the pins 6 being :threaded through the fabric and holding same in' position with the frame ends which are rounded at 3* bearing thereon. v l

The frame sections are held in extended position as shown in Fig. 1 by a latch 8 which is located between the frame members at their pivoted ends, being fulcrumed between 1 its ends by depending apertured lugs '9. mounted upon a barlO extending transversely of the frame and bearing at its opposite ends in the sides ofthe frame section 3 nearthe upper edges thereof and adjacent the pivotal connection of, the sections. In the preferred constructionthe latch is of plate form and extends, in a flatposition,substantially from side to sidev of the frame, one end ofkthe latch presenting integrallugs "orf fingers 11 which.

1 extend laterallyfrom the latch over the sides of the frame section 2 and are adapted to engage shoulders .A thereon which are most .suitablypresented by forming notches 1 2 in the upper edges of said framefsection. This engagement ofthe latch with" the section 2 and the connectionpf the ,latch with, section'3 through the bar 10,

establishes a ri 'dconn'ection between the .two sectionsan ,preventstheswinging of same toward each other whilethe direct engagement ofsaid latch with section. 2 eliminates intermediate parts The end 13 of the latch is'llpwardly ofl'setabove the normal plane of the main portionfof thelatch to form a convenient presser portion whereon pressure can be applied and the latch rocked on its fulcrum to disengage the fingers from the'frame.

A coiled spring 14'enci rcling one end of the bail 4 where it extends inwardly beneath the latch forms the sides of the framcsections, has one end thereof engaged with one side of section 2 and its opposite end 16 bearing upon the underside of the presser end 13 of the latch thereby tending to yieldinglymaintain theclatch fingers 11 in V engagement with frame section 2.

, When it is desired to collapsethe frame to;loosen the mop fabric so that it can be squeezed. out or renewed, the presser end of the latch is depressed thus permitting the sections 2 and 3 to be swung'inwardly toavard each other. Thisswinging movement of thesection is yieldingly resisted and sud- 'den collapsing of the frame prevented by said spring l t-which in addition toinfluencing the latch alsov provides a connection between the two frame sections when the latch is disengaged from section 2, such conv.nection being set up through the engagement of the end 15.with section 2 and the engagement of end 16withthe latch and through the latter, with sectionc3. In order, however to permit of the sections being swung to a position with their free endsin close proximity to each other so that the ends of the mop fabric are brought close together and the fabric thereby so folded as to be s conveniently inserted in a wringer for practically its whole length, I have made section 30f less width than section 2 and disposed the pivoted ends of the former within those of section 2 thus permitting an intimate folding of the sections 'as'sliown in Fig-2, wherein section2 straddles section 3 for the major-portion of its length.

The frame is firmly braced atthe center by abridge-piece which is formed tofirmly support and brace the different members without interfering with theldescribed move H I ments thereof. Said bridge-piece consists of a flat metallic strip 17 extending between the "sides ofsection 3 beneath the intur'ned ends of bail i and 'havingiits" ends [extended T upwardly at 18'inside the pivoted'ends of r thefiframe sections to 'thez top edge thereof,

then continued outwardly "over such pivoted ends and downwardly. as at 19 on the outer s depf the latter, thus fornrling downwardly f fac'ing hooks straddling the ends. of the'sectiof splThe upwardly and downwardly extending ends of the britlge piecex are' suitably apertufe'd for the "passage of the inv ward y xtend g ends f th ba e through, said bail ends being thus provided of the ba1l.'

with bearings at, these points "apertured lugs 20 struckfup from the strip 17 ovidebe'arings for th ,I t-i'eme' inner endst 7 The bridge-piece is rigidly fixed'to section 3 by the bar 10 which passes through notches 21 in the upwardly extending portions 18 bridge-piece and said section, the collapsing of the frame being, in this construction, ac- 'complished by the swinging of section 2 which has its pivoted ends rounded at 2 to provide ample clearance betweenthem and the overhan in portions of the hooked ends D of the budge-piece.

"and prevent, relative movement between'the The above described bridge-piece provides be constructed so that the space between the bottom edge of each side of the under section 2 and the bottom edge of each side of; the

' narrower section 3 overlapped thereby, is

left unobstructed'from the free ends of" the sections tothe closed ends thereof; This construction permits theabove described intimate folding to be accomplished.

v In the preferred construction the strip17 is located below'the level of the lower edges of the pivoted ends of sections 2 and '3 to providea flat, surface extending from side to side of the frame at the center thereof and below the level of'the central portion of the frame for the purpose of providing a'firm' bearing upon the fabric at this point and to elevate the frame at the center topromote I the accumulationof dirt and like foreign matter at the center of the fabric mop and prevent similar accumulation at the sides thereof where it wouldbe continually spread over the surface being moppedl' Y i A' hook 22 pivotally carried by the frame section 2 is'adapted to swing'over and engage the bail 4 carrying the handle and thus hold same securely to the frame; With this arrangement one end of theframe may rest 'upon the floorand the cloth, being in stretched out position wi-lldry quickly.

A mop frame constructed as above de-"' the majority of themembers being stamped out from sheet metal-and readily formed, the simplicityof their construetion and par- 7 scribed "can be economically manufactured, i
