My invention relates to improvements in wax applicators, and the primary object of the invention is to provide a device or this character in which the operating mechanism is entirely enclosed; and which is of a simplified and less expensive construction, and which is especially arranged to facilitate and economize in the application of wax to afloor or other surface.

Other important objects and advantages of my invention will be apparent froma reading of the following description taken in connection with the appended drawings,wherein for purposes of illustration I have shown a preferred embodiment of my invention.

Inthe drawings:

of the combined reservoir and handle l6.

Figure 2 is a fragmentary left hand side elevational view thereof.

Figure 3 is a fragmentary enlarged side elevational view of the hand grip portion.

Figure 4 is a vertically contracted enlarged longitudinal sectional view taken through Figure 1 along the line 4-4 and looking in the direction of the arrows; a

Figure 5 is an enlarged horizontal sectional view taken through Figure 1 along the line 55 and looking in the direction of the arrows.

Figure 6 is a top plan view of the combined handle and reservoir.

Figure 7 is a bottom plan view of the lower end of the hand grip portion.

Referring in detail to the drawings, the numeral 5 generally designates the applicator which may comprise a generally conventional applicator head including a transversely elongated relatively rigid plate 6 having upturned edges 1, with a felt or other suitable material applicator body 8 arranged across the bottom of the plate 6 and having its edges overturned around the projections 1 in an inward direction and held down in place by spring bails 9 and I mounted on brackets ll attached to the plate 6. Pivoted at I2 on the said brackets are the lower ends of upwardly converging bars l3 and I4 which are rigidly secured to diametrically opposite sides of the tubular valve body l which is threaded on the lower end of the combined handle and fluid wax reservoir which is generally designated Hi.

In the present instance the valve body IS includes the beveled annular flange IT at its lower end constituting a liquid wax nozzle for guiding the stream of wax released by the valve onto the floor in rear of the applicator head, as indicated in Figure 2 of the drawings. Above the nozzle I I is the partition [8 which is provided with a central opening terminating in a valve seat IS, the interior of the element I5 being threaded at 20 to accept the lower end of the combined reservoir and handle l6, as shown in detail in Figure 4 of the drawings. A mushroom type valve 2| is positioned relative to the valve seat l9 and is connected on the lower end of the valve operating rod 22 which extends through the opening in the partition l8 and up through the entire length The rod 22 has a stop pin 23 retaining a washer 24 which directly engages the upper end of a helical expanding spring 25 which is compressed and has its lower end engaged with the top of the partition l8, whereby the valve 2| is held normally seated in the seat l9 to close oii gravitational discharge of the liquid wax 26 in the handle IS.

The upper end of the combined reservoir and handle 16 is providedinteriorly with a diametrical web 21 through the center of which the upper end of the rod 22 slides and is exposed above the element 21 a sufiicient distance to enable sufficient depression of therod 22, in a mannerto be described, to completely unseat the valve 2|. As indicated in Figure 4 the element 21 is depressedsomewhat below the upper end of the handle I6 which isexteriorly threaded'asindicated by the numeral 28 and to threadably enter and connect the lower end of the hand grip which is generally designated3ll.

The hand grip 30 comprises a tubular elbow 3| which has adjacent its lower end a partition 32 in position to press an annular gasket 33 onto the upper edge of the handle I6 to firmly connect the handle portion 3|] with the upper end of the handle and prevent escape of fluid, in this case, the liquid floor wax, from the upper end of the handle. The open upper end of the handle provides the medium whereby the liquid wax is introduced into the handle reservoir l6.

Telescoped in and secured within the upper end of the elbow 3| is a suitable hand grip 34 which may have a cylindrical shape as shown or some other suitable shape.

Between the hand grip 34 and the lower end of the elbow 3| there is formed a vertical slot 35 in the crook of the elbow through which extends the bill portion 36 of a trigger or operating lever which is generally designated 31 which is mounted on a pivot 38 traversing and secured in the sides of the adjacent portion of the elbow, the

portion 36 of the lever 31 being suitably curved and positioned for easy operation by the fingers of the operator when gripping the handle portion 30.

Within the elbow 31 the trigger has a right angularly related suitably curved cam portion 39 which bears operatively upon the upper end of a plunger rod 40 which works in an opening M in the center of the partition or web 42 and has below this partition an enlarged head 43 arranged for operative engagement with the upper end of the valve operating rod 22. Above the partition 32 the rod 40 has circumposed thereon an expanding spring 44 which works between the top of the partition and a washer 45 on the rod 40 and is held in place by a pin 46 thereabove.

As a result of the arrangement described, the combined reservoir and handle l6 being supplied with liquid wax, and the handle portion 30 having been connected in place on the upper end of the handle I6, the operator need only to draw the portion 36 of the lever 31 in an upward direction, as in pressing the trigger of a gun, to cause a discharge upon the floor or other surface being waxed, of a selected amount of the liquid wax. Thereupon the applicator head of the device need only be moved over the floor or other surface to distribute the wax in the ordinary manner.

It will be observed that with all of the operating mechanism with the exception of the lever 1 31 enclosed and concealed within the main body of the device, there are no parts to catch in objects and become impaired in their operation by engagement with outside objects, and to be subjected to deterioration due to exposure. the same time, the construction and arrangement of parts set forth above provide for economical manufacture, a reduction and simplification of parts, and a reduction in useless Weight, with consequent savings in manufacture and shipping costs. These advantages are entirely apart from and in addition to the obvious mechanical superiority due to the fewness of parts and direct and fool-proof action thereof.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not wish to limit the application of the invention thereto except as may be required by the scope of the subjoined claims.

Having described the invention, what is claimed as new is:

1. A wax applicator comprising an applicator head for reciprocation over the surface to be waxed, a combined handle and liquid reservoir connected at its lower end to said applicator head and comprising a tube open at its upper and lower ends, a valve normally closing the lower end of said tube, a valve operating rod enclosed within said tube and connected at its lower end to said valve, a handle portion removably connected to and closing the upper end of said tube, and a manually operable lever on said handle portion, said lever being operable to actuate said rod to open the valve.
