This inventiony relatesl to an improved: liquid Waxapplicator, for use-for example inwaxing linoleum or wood oors. andV theV like.
One of the objects of= the invention is to-.provide anv improved wax applicatorforb the purpose described, which is of improved structural.' sinrplicityand ruggedness andrelatively inexpensive to manufacture and maintain in perfect working condition. Y
Another. object of the invention is to` provide a deviceA of the character` described which incorporates an.: improvedwax dispensingV control valve arrangement.
Another object of: the; inw-intimil is'l to provide in. a device of the character.Vv described: an'y im proved control arrangement for-thervalve mechanism which. regulates they ratei of application of. wax fromA the device.
Another object of'4 thevv invention` is toiprovide in. ay device of the character describedv an improved valve unit which may. be' easily. assemliledy and/or removed from the device for serviceing purposes. l
Another object of the invention is to provide a'device of the character desoribed whichA em-v bodies a relatively large wax'reservoir' While be ing, atthe same time ofr unusuallyl compact and? lightweight construction.
Another object of the invention isft'oy provide'a device of the characterdescribedi which: is most convenient to use andto service;
Other objects and advantages of th'e'invention will appear inA thespeciiication hereinafter.
Inthe drawing:
Fig. 1 is a top perspective View of'arwax applicatoroi the invention; andi Fig. 2` is a transverse vertical; section there'` through, on alarger scale.
The drawings illustrate` the invention tofcomiprise essentially housing indicate'df. generally. at lll. which. is attached to a handle |52.' forvconvenient manipulation of the. waXer. Thus; itv will4 beunderstood. that the handle i12 may be of any desired shape andy dimension, and will. be forrned of any suitable material as maybe preferred. The housing structure HJ comprises a box-like sheet metal fabrication having sid-eeY and'. top wall. portions lll-i6 and end platesv |581.' The bottom. of the hou-sing lois partiallylenclosedf by a flanged sheet metal bottom' platev 20.- which`v is generally rectangular in. outer contour. to: complement the side and end` wall marginal por.- tions of` the walls lll-i8. The upturnedside` flange portions 22 of the bottom-.plate 20 may be" spot-welded or soldered or. otherwise suitably through' the interior of the housing attached.' to y thei bottom.` edges; of? the wallplates oftthe housing le. Atthegecmetricloenterothe bottom-platefit isfforrned Witha circular aperturezd.
Interiorly of the vhousing I ilna horizontal-pars tition plate? 26 is providedto-extendvin parallel spaced relation above the bottom plate 2U; and isiv searri-weidedy on soldered: or..v otherwise.l suitably attached to-theside Walllportions lll-I8 ofthe housing it, asy by means of` a depending.- 'ange 28 formediintegrally. with the partition plate 26 The plate 26l is centrally reinforced! byV ametal plate 3x9,` and; theplate.y elements 264-30; are` circularly bored and threadedV asf indicated` at 32; inf linewith the apierlfure 24 which is formed through the bottornlpl'ate 2D; The valve unit' is illustrated to comprise-peripherally knurledfbase plate134-having a 'diameter greater thanithedii ameter ofy the; aperture 3-2f through the partition plate. Thel base plate 34: mounts. at itsV upper faceI andA aperipherallyN threaded topy plate 36 which is so dimensioned and threaded as to beV adapted to screw into. and' outv of; connection with thepastition plate; elements 26`-30L TheV top plate 36 may. be attached to the platev 34 asby means oi screws 335-38; or'by welding, or any other suitablemeans.-
The plates :i4-35' are centrally boredl to provide a valve. porti 39, and a` valve plate 4ll is pivotally mounted as: at 42' upon the top plate? I3&5; andY is din'iensioned` so as to normally close the valveport 39; A crank arm 44 extends froml thevalve:plate` Mlizand is forked' and adapted at its! upperv end to receive in freely rotatable relation therein. thefreducedF neck portion 46 or thev valve controll stenreB.. The crankv arm All' is also' formed with a tab portion 4.9i which engages againstl the upper fendi ofy a compression Yspring 5,0.; the'lower endlof# thespring llibeing disposedj' to .bear vdownwardly against the top-plate 35 andJ tofbe positioned thereon by means of an` abut-l ment 521v Thus; the spring 5l] normally biases the valvefplateill into valveport closing position:
l The Valve stem` v4H! extends obliquely upwardly 50; by means? of" a metal plate 56' which is spot-V weldedror-otherwise.attached tothe housing wall.
A screwthreaded nutv 58 is also shown as beingI welded' or. otherwise fixed' tothe reinforced housingz wall portiona. The housing wall structure' and the nutvv 58: are suitably.1 threaded so` as to engage the threaded body portion of the valve stem 48 so that rotation of the valve stem 4B in one direction from externally of the housing will cause the crank arm member 44 to be pushed down so as to open the valve plate 40 relative to the port 39. Upon reverse rotation of the valve stem 48 the latter retreats, thereby permitting the spring 50 to return the valve plate 40 to port-closed position.
At its outer end the valve stem 48 carries a. pivot pin 6D which is connected to the handle structure I2 previously referred to; and as illustrated in Fig. 2 the handle construction may conveniently include a socket portion 52 into which is slip-fitted and pinned any desired form of handle 64. Thus, it will be appreciated that the operator of the waxer may pivot the handle I2 vertically to any preferred attitude for most convenient use of the device while pushing and pulling the applicator back and forth across a floor surface or the like. Also, it will be understood that simple rotations of the handle l2 in opposite directions will procure corresponding opening and closing movements of the valve device, so as to control the ow of liquid Wax, a supply of which` is indicated at 65, through the valve port 39.
A polishing pad of cloth or other porous fabric or the like as indicated at 1U is stretched across the bottom of the bottom plate 20 and thence upwardly around the side edges thereof. A band as indicated at 12 is then applied around the marginal edges of the pad 10 to clamp the latter firmly against the sides of the housing. A clamp 14 or some other suitable device is preferably employed to clamp the band 12 firmly against the fabric. Also, a rubber bumper band 15 is preferably slip-fitted over the band 12 to provide a perimetral bumper extending all around the housing l so as to enclose the assembly and prevent scarring of furniture and the like when the applicator is in use.
'I'he fabric pad 1D is readily detachable from the housing, whereupon the larger opening 24 is uncovered so that the valve unit may be readily inserted or withdrawn through the opening 24. For filling the wax reservoir a filler-opening 16 and a screw cap 18 is provided in the top Wall of the housing. Preferably, a gasket as illustrated at 80 will be employed to more perfectly seal the luncture between the valve unit and the partition plate 26. Thus, it will be appreciated that the invention provides a structurally simplified housing comprising a liquid wax reservoir having a horizontal partition plate in the bottom portion thereof; said plate being formed with a threaded aperture into which an externally threaded valve unit may be readily assembled and disassembled without disruption of the rest of the structure.
Although only one form of the invention has been shown and described in detail it will be apparent to those skilled in the art that the invention is not so limited but that various changes may be made therein without departing from the spirit of the invention or the scope of the appended claims.
