Application November 19, 1948, Serial No. 60,906

1 claim. 1

rThis invention relates to floor wax applicators,

Vand more particularly to a fountain-type applicator for liquid wax.

It is among the objects of the invention to provide an improved liquid Wax applicator which will contain a quantity of liquid wax suiicient to cover a iloor of usual size, and which will dispense the wax under manual control to apply the proper quantity to the floor, which applicator is of simplied and durable construction, includes a minimum number of simple parts, is of light weight, and is extremely economical to manufacture, and easy to assemble and use, and provides a substantially leak-prooi construction, so that liquid wax may be retained therein over long periods of time without loss.

ther objects and advantages will become apparent from a consideration of the following description and the appended claim in conjunction with 'the accompanying drawing, wherein:

Figure 1 is a top plan View of an applicator illustrative of the invention;

Figure 2 is a longitudinal, medial cross-section on an enlarged scale of the applicator shown in Figure l, certain portions being broken away and omitted in order to simplify the drawing;

Figure 3 is a side elevation of a valve plug, valve and valve-closing unit constituting an operative component of the applicator; and

Figure l is a transverse cross-section on an enlarged scale taken substantially on the line 4--4 of Figure l.

With continued reference to the drawing, the improved applicator comprises, in general, an elongated tubular handle I0, an elongated, cylindrical plug II received in one end of the handle in iluid-tight engagement with the latter, a pair of angle brackets I2 secured to the plug I I and to the plug-receiving end of the handle at respectively opposite sides of the latter, a pair of plates I3 and I4 superimposed relative to each other and carried by the angle brackets I2 at a location spaced from the plug-receiving end of the handle I, a wax-applying pad I5 clamped between the plates by suitable bolts 25 and wing nuts I6, a valve piston I1 engageable with a valve seat in the inner end of plug II, valve-closing spring means I8, a manually-movable, hollow cap I9 receiving the end of handle I0 opposite the plugreceiving end of the latter, and a jointed connector 20 connecting the cap I9 to the valve piston I1.

The handle Ill may be conveniently formed as a length of thin-walled aluminum tubing of proper diameter, and the valve plug II may be a cylindrical body of the same material having an outside diameter substantially equal to the inside diameter of the tubular handle and having a concentric, longitudinally-extending bore 2I which terminates short of one end of plug I I and a pair of diverging holes 22 extend from the end of bore 2l adjacent the one end of the plug to such one end of the plug, that is, the outer end of the plug, and a cylindrical counterbore 23 is provided in the inner end of the plug and has an annular valve seat at its inner end.

The two angle brackets I2 are secured to the plug II and the handle Ill by spaced-apart cap screws 24 which extend through registering apertures in the brackets and the handle and into screw-threaded Wells provided in the plug to secure the brackets, and the handle and the plug together in assembled relationship. Bolts 25 extend through registering apertures in the plates I3 and I4, and the end portions of the brackets I 2 opposite the handle and receive the wing nuts Iii to clamp the rectangular plates i3 and I4 together. The pad I5 may comprise a piece of sheepskin with the wool thereon doubled over and clamped between the plates I3 and I4 by the bolts 25 and wing nut I6 for applying liquid wax to a floor.

A pair of short tubes 2S extend through the outwardly-diverging holes 22 of the plug in outwardly-diverging relationship and have their inner ends joined together at the end of bore 2l adjacent the outer end of plug I I. The short tubes 26 are sealed at their inner ends to the plug II at the corresponding end of bore 2| in iluidtight relationship and diverge respectively toward the adjacent angle brackets I2 to direct liquid wax from the bore 2| onto the pad I5.

A support plate 2l having a central aperture therethrough is held in position spaced from the inner end of the plug II by a pair of supports in the form of elongated screws 28 which extend through respective apertures provided near the opposite ends of plate 21 and into screw-threaded wells provided in the end of plug II at diametrically'opposite positions. The valve piston I1 is a cylindrical body having a metal core 29 and a covering of resilient material, such as rubber, and has a tapered end portion received in the cylindrical counterbore 23 and engaging the annular valve seat around the end of the counterbore when the valve is closed. A valve stem 30 is secured at one end to` the core 29 of the valve piston and extends slidably through the central aperture in the support plate 21. At its outer end this valve stem 30 is provided with an apertured eye 3 I.

A coiled compression spring 32 surrounds the valve stem between the plate 21 and the valve piston I1 and resiliently urges the Valve piston into seating relation with the annular valve seat in the inner end of plug I I, and a U-shaped wire or staple 33 is passed through a transverse aperture provided in the valve stern 30 adjacent the eye 3| and has its legs disposed in notches provided inthe opposite longitudinal edges of support plate 21 to hold the valve stem against rotation relative to the support plate and the plug II. g

The cap I9 is a cylindrical body having one thick end wall 34 and a cylindrical iiange 35 extending longitudinally from the outer edge portion of the end wall to telescopically receive the end of handle I opposite the plug-receiving end of the handle. The end wall 34 is provided with a screw-threaded well which receives the eX- ternally screw-threaded end portion of the connector 20. The connector 20 comprises a rod 36, one end of which is threaded into the end wall 34 of cap I9, and the other end of which is provided with an eye 31. A link 38 has at one end an eye 39 engaged in the eye 31 of the rod 3B, and at its opposite'end an eye 40 engaged in the eye 3| of the valve stem 30, so that when the cap I9 is manually pulled outwardly of the handle I0 the jointed connector 2) pulls on the valve stem 30 and moves the valve piston I1 away from the valve seat in the inner end of plug I I, permitting liquid wax to flow from the interior of the handle I0 through the bore 2I of the plug and through the tubes 26 to the pad I5.

When it is desired to supply liquid wax to the interior ofthe handle I0, the cap I9 is pulled away from the adjacent end of the tube 26 and moved sideways to uncover a portion of the corresponding or upper end of the handle, so that the wax can be poured into the handle.

In using the device the cap, threaded onto the adjacent end of the connector 20, is pulled outwardly to open the Valve whenever it is considered necessary to replenish the supply of wax on the pad I5, and the wax is applied from this pad to the floor by rubbing the pad over the oor in the usual manner.

The wire staple 33 holds the connector 23 against rotating when the cap I9 is screwed onto and off of the outer end of the connector.

The invention may be embodied in other specilc forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claim rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claim are, therefore, intended to be embraced therein.

What is claimed is:

A liquid dispenser comprising an elongated, tubular handle constituting a liquid reservoir, a q ylindrical plug disposed at one end of said handle in Huid-tight engagement therewith, said plug having a concentric, longitudinal bore extending partly therethrough from its inner end with a pair of holes extending from the outer end of said plug to the adjacent end of said bore and diverging in a direction away from said bore, said plug having a counterbore in its inner end terminating in an annular valve seat, a pair of tubes inserted one into each of the holes in said plug and diverging beyond the outer end of said plug to convey liquid outwardly from the corresponding end of said tubular handle, an apertured plate spaced from the inner end of said plug, spaced-apart supports disposed one support near each end of said plate securing said plate to said plug, a valve piston seated in the inner counterbore of said plug, a valve stem secured at one end to said valve piston and extending slidably through the aperture in said plate, a cornpression spring interposed between said plate and said valve piston to resiliently hold said piston in huid-sealing engagement with the valve seat at the inner end of said plug bore, a hollow cap slidably receiving the end of said handle opposite the plug-receiving end of the latter, and a connector connecting said cap to said valve stem for movement of said valve piston away from said valve seat upon movement of said cap outwardly of said handle, said cap being movable relative to the adjacent end of said handle for uncovering at least a portion of the end of said handle for filling said handle with liquid.
