(Cl. 1'5--231i 5.Glaims. i

This invention relates toimprovements in pad holder and pad means for use in the cleaning and conditioning of oors; wailsand the; like.

The presentiinvention isin the-nature oi` an improvement on the pad holder and pad.'v means disclosed in my prior patent application Serial Number 594,645, led May 19, 1945 (now abandoned).

The general object of my invention is to pro.- vide a mop typepad holding devce'- which may be used by a person in' av standing position lto clean or condition a wall or. 'oor bythe use of the proper cleaning, waxing and polishing pads.

Another object islto providea padhold'er and pad means that may` beleiiieientlyused' in applying cleaners to a surfaceto becleaned without requiring the user toA getv these cleaners on the hands, thus making it' possible'to safely use cleaning solutions that will injure the hands if they come in contact therewith.

Another object offthis invention is to provide a mop type pad'holder to whichk various-pads of the form commonly used to:conditionziioorsiand walls may be veri/'quickly and easily attached: and detached thus making `this device especially suitable for home use rto keepA oorsand'walls in good con'- dition.

Another object is to provideapad holder comprising a substantially flatiplaten havingfangle shaped grooves in its bottonnside along its front and rear edge adapted to receive the, edgeportion of a pad that. extendsV across said platen and having resilient' pad gripping means adapted to be drawn against said pad and into said grooves to secure the pad tothe platen.

Other objectsy of the invention-will be apparent fromvthe foilowingdescription taken ,inconneetion with the accompanying drawings.

In the ydraw-ings- :igurel is a planview of` a pad'holdingdevice constructed in accordance4 with thisv invention looking in the direction of vbroken' line I-i of Fig. 2 and showing'the-pad`A gripping means inxan open position, a portion ofthe;handle-being brei. ken away.

Like reference numerals designate like parts tlfiroughoutthe several views.

The pad holding n'ieanssl'iowniinligs.` 1 to 6 comprises a flat rectangular; block orplaten Il) having a handle Irl secured to; the,V upper side thereof 'by any suitable means, such as abracket I2. Preferably the handle Hf isabout thesame length as an ordinary-:broomor mop handle and is positioned at aboutthe angle shown in the drawings tothe planeoi-,the platen for convenient application to the ioor; or wall.

TheY bottom surface;otheplaten.` Ihasan angularly shaped groovev If extending along` its iront. edge and anotherangularly shaped groove I4' extending along its rear edge1to receivethe marginal portions I5 of a pad I6. Padsoffdifferent type may be used depending: on'` thel work to be done. Forinstancethe pad-maybe a. steel woolipad or it may beiapad body with sandpaper drawn over it, orit'may beapad withV wax folded into'it `or'it maybez'azpolishingfpadfor afmop pad. In. all instances' the padsf will be,- provided with marginalportionsz corresponding to the portions I5. and with amain pad portion suitable for the work to be done.

The edges l5-of any pad Itthat is to befused are iirmly` gripped and"securely-held by` two resilient pad clamping wires VIj and I8 that coop@ crate with the respectivegrooves IS and I4. The pad clampingwires I'lrv and' i8 extend across the bottom of the platen` i!) andare thence bent at right angles and extend upwardly past the ends of the platen I0 through notches I9 in the ends of said platenr and. are thence converged. as best shown in Fig. Land: have hookV shaped bends 20 on their upper ends; The-hook shapedvmembers 2U engage Within holes 2l ina slidemember. The slide` member-"422: is of inverted U shape in cross se.ctionseel Fig. 4.V The. bottom edges of the slide member 22 are bentz1outwardly andare slidably held and` guided' beneath theinwardly bent portions. 2e' of a tracleplate 24.- The, trackv plate 24 is secured tothe handler I I-, as by screwsV 25.. A binding wire 26 extends substantially" all of the way around Athe platen Id and has end portions. 2T that aredriven intothe platen to hold said wire in proper position. Preferably thistbindngwire 2tV is; countersunk into Vthe edges and-.ends of the -platen itl.. This bindingwirevzi extends vacrossthe notches I9 that `thepad clamp.- ingA wires I1 and lfpass through and cooperates with the notches I9 in forming guide and retaining means for the pad clamping wires l1 and i8.

The slide member 22 is connected by a U- shaped wire link 28 with a lever arm 29. The lever arm 29 is connected with a bracket 39 by a pivot member 3l. The bracket 3i) is secured to the handle H near the upper end of the guide member 23--24. The rear or upper end portion of the link 28 passes through a hole 32 in the lever arm 29 and the forward or lower ends 33 of the U-shaped link 28 are bent inwardly and shaped like hooks and are engaged within holes 34 in the slide 22. The pivot 3l in the bracket 3l! is far enough away from the handle Il so that the line of pull of the link 28 will cross from one side to the other of the axis of this pivot 3l in the operation of the lever 29. This line of pull on link 28 will be between the axis of the pivot 3i and the handle H when the lever 29 lies against the handle l l and will be on the other side of the axis f the pivot 3l when the lever 29 is moved outwardly away from the handle H. Thus the line of pull of the link 2B will pass the center of pivot 3| and a self locking link and lever structure will be provided.

t The portions of the pad clamping wires l'l and yl! that operate in the slots i9 are substantially straight and substantially at right angles to the pad clamping portions of said wires and are joined to the convergent' portions of these wires by bends 35. When tension is exerted on these wires it tends to straighten them at the location 'of the bends 35and this contributes to the resiliency of the wires and makes them self adjusting to pads having marginal portions l of varying thickness. Preferably the pad engaging portions of the wires l1 and I8 are curved or bowed as shown in Fig. 2 to provide a rrn grip on the edges l5 of the pad all of the way across the platen. v

y The two pad clamping members l1 and IS are spread apart a greater distance at the location where they pass through the notches i9 in the platen I0 than they Vare at the location of the slide member 22, see Figs. 2 and 3. This provides a divergence of these pad clamping members which makes it easier to insert and remove pads than it would be if said wire pad clamping members did not so diverge. When these pad clamp- -ing members are moved from the position shown in Fig. 3 to the position shown in Fig. 2 they will be spread apart at the same time they are moved outwardly away from the platen l2. Thus they will drop any pad held thereby and will be wide enough apart to permit quick and easy application of another pad to the platen l0, after which the members il and i8 can easily be clamped against the pad so applied. The ease with which the pads are applied to and removed from this device renders it particularly desirable for ordinary home use. l

The foregoing description and accompanying drawings clearly disclose a preferred embodiment of thisinventlon but it will be understood that this disclosure is merely illustrative and .that such changes in the device may be made as are within the scope and spirit of the following claims.
