Claims. (Cl. 15131) The present invention relates generally to improvements in the art of waxing or polishing floors, and relates more particularly to improvements in the construction and operation of liquid wax dispensers for floor polishing devices.

A primary object of the present invention is to provide an improved liquid wax or polish dispenser which is readily adaptable to any standard and commercially available floor polishing mop or similar device, and which is moreover extremely simple, durable and compact in construction as well as highly eflicient in operation.

It has been heretofore proposed to provide handled floorolishers or mops for use withliquid wax or the like in polishing floors, and while these floor polishers are of somewhat varied construction, they all consistgenerally of a floor; engaging polishing head having a manipulatingthandle extending upwardly= therefrom at somewhat of an angle to the-floor. in most cases, no provision is made for supporting or carrying. a supply of polish or Wax directly on the. polishing. device and for mechanicallydistributing desired and necessary amountsthereof to the head during the polishing operation, thereby necessitating frequent interruptions and stooping or bending operations for separately dispensing quantities of the polish by hand over the unpolished areas. In other cases however, it has been proposed to incorporate liquid wax housing means and valve controlled dispensingmeans for. such wax as an integral part of thepolishing device; but suchdevices must generally be of special and relatively expensive construction and are usually also complicated' and bulky. In a few instances, it has further been proposed to provide polish housing and dispensing means adapted for merchandising as an attachment for existent floor polishing mops and the like; but in all such cases, the attachments have encountered very little commercial. success and acceptance due to their inefficiency in operation, bulkiness, cost, difficulty in application, or the rather complicated nature thereof.

Itis therefore a more particular object of this invention to provide'a polish housing and dispensing attachment: which. obviates all of the disadvantages and objections attendant. prior orpreviously proposed devices of this'general type.

Another specific object of the invention is to provide an improved liquid wax dispensing attachment which is readily applicable to any standard and commercially available floor polisherswithout need for specialtools and which may moreover be manipulated in'a most conveni'ent-manner by'a novice.

Stillanother specific object of our invention is to provide a new and improved polish dispensing accessory which comprises relatively few simple parts, all of which may be readily manufactured of suitable material andall of. which are readily accessible for inspection, replacement or repair.

A further specific object of our present invention is to provide an improved liquid polish dispensing device 2 which is extremely flexible in its adaptations and which may be quickly and easily assembled, dismantled, cleaned and stored.

An additional specific object of the present invention is to provide an improved polish dispenser comprising, a container for housing a supply of liquid polish, means for securing the container to the handle of a floor polisher,. a conduit communicating with the container for conducting polish to the polishing head, and means extending be-' tween thecontainer and the polisher handle and coacting with the conduit for controlling the flow of liquid polish therethrough.

These and other specific objects and advantages of the invention will be apparent from the following detailed description.

A clear conception of the several features constituting our. present improvement, and of the construction and operation of a typical liquid wax dispensing accessory as applied to a standard floor polisher, may be had by referring-to the drawing accompanying and forming a part of this specification; wherein like reference characters designate the same or similar parts in the several" views.

Fig. 5- is a similarly enlarged fragmentary perspective view of the flow control valve mechanism and again showing the valve in-closed positionyand- Fig. 6 is another enlarged fragmentary perspective-view of one of 'the conduit retaining clamps and the flexible polish conducting conduit.v

While the improved dispenser has been specifically shown and described herein as being especially advantageously applicable as an accessory to a particulartype of floor polisher-for use in dispensingliquid wax, it is-not our desire or intention to unnecessarily limit the scope or utility of the invention by reason of such restricted embodiment; and it is also contemplated that certain specific descriptive terms used herein shall be given the broadest possible interpretation consistent with the disclosure.

Referring to the drawing, the: improved liquid waxdispenser is shown therein as applied to a conventional floor polisher having a lower floor engaging polishing head' 8' of cloth, sponge rubber or the like and an upwardly extending and rearwardly inclined handle 9 terminating at its upper end in a gripping and manipulating portion 10; The improved dispenser comprises,.in general, a container 11 formed of suitable material for housing a supply of'liquid wax or polish 12, the container 11 having its open end normally closed by a suitable lid' or cover 13 and being formed with an apertureddis'charge nipple 14 in its bottom wall; means such as a bracket member 15 secured to a medial portionof the handle 9 by a suitable adjustable clamp 16 or the like and adapted to detachably receive the'container 11 and retain the saine securely'in p'osition'insp'aced relation to the handle 9; a flexible. tube or conduit 17 having one end attached to"the'nipp1e'14 for communication with the interior of the container 11 and having the opposite or discharge end thereof" disposed adjacent to the' polishing head 8 for'conducting liquid wax thereto, the conduit 17 being retained in position by a number of suitable clamping elements 18 frictionally coacting with the conduit and with the handle 9; means such as a bifurcated lever 19 suspended within and extending through the space betweenthe container 11 and the handle 9, one end of the lever 19 extending beyond the upper end of the container 11 to a point near the manipulating end 10 of the handle 9 and the opposite or bifurcated end of the lever extending somewhat beyond the lower end of the container 11; a flow control element carried by the lower bifurcated end of the lever 19 and coacting with the conduit 17 below the nipple 14 for controlling the flow of liquid wax through the conduit upon manipulation of the lever 19; and means such as a spring 21 coacting with the lever 19 for constantly resiliently urging the lower end of the lever away from the conduit 17 to a position whereby the flow control element 20 closes the conduit and restricts the flow of liquid wax therethrough.

As indicated, the container 11 and its cover 13 may be conveniently formed of plastic, metal, or other suitable material with the nipple 14 being molded or otherwise formed integral with the container, and the cover 13 may be retained in position either by snug frictional engagement or it may be threaded in a well-known manner with a vent opening 23 preferably being formed therein to permit entrance of air to the interior of the container to displace the liquid wax drawn therefrom. In addition, the container 11 is formed with an elongated outwardly open dovetail slot 24 extending along the outer wall from the closed bottom end to a point somewhat short of the upper open end of the container; and the bracket 15 is formed with an outer elongated platform 25 adapted to slidably enter the dovetail groove or slot 24 of the container 11 to retain the same in its position in spaced relation to the handle 9, the base 26 of the bracket 15 being preferably formed with depending side lugs 27 for snugly engaging the rounded surface of the handle 9 upon application and tightening of the clamp strap 16 by means of the bolt 28 or the like. To provide a fulcrum for the lever 19, the bracket 15 may also be formed with integral saddles 29 on opposite sides thereof; and each bifurcation of the lever 19 is provided with an inwardly directed approximately semi-cylindrical fulcrum projection 30 adapted to be seated in one of the saddles 29, the lever 19 being preferably formed of relatively flexible or resilient material to permit spreading of the bifurcations for ready application thereof to or removal from the bracket 15. The flow control element 20 may be conveniently formed of relatively heavy and stiff wire or the like bent to substantially U-shape with one leg thereof frictionally carried within corresponding slots 31 in the lower ends of the bifurcations of the lever 19, the other leg of the flow control element 20 spanning the flexible conduit 17 above a notched extension 32 of the bracket platform 25 so as to pinch the conduit 17 closed when the lower or bifurcated end of the lever is in normal lowermost position as shown in Figs. 1 and 5. The spring 21 for constantly resiliently urging the lower end of the lever 19 toward the handle 9 and away from the conduit 17 may either be in the form of a suitable coil spring or a band spring as shown, and this spring 21 may be conveniently located between the platform 25 of the bracket 15 and a seat on the lever 19 formed by a pair of inwardly directed integral flanges 33 formed on the bifurcations of the lever. As shown in Figs. 1 and 2, the handle engaging base 26 of the bracket 15 may be formed with a somewhat enlarged shelf portion 35 to provide a second seat for the clamping strap 16 when it is desired to apply the device to a polisher having a thinner handle 9.

In actual use, the improved dispensing accessory may first be assembled by spreading the bifurcations of the lever 19 and longitudinally applying the same to the bracket 15 with the fulcrum projections 30 seated in the saddles 29. The spring 21 may then be positioned within the bracket 15 between the platform 25 thereof and the flanges 33 of the lever 19, and the free ends of the bifurcations of the lever may then be squeezed toward each other with one leg of the flow control element being forced into the slots 31. Pressure may then be exerted on the upper end of the lever 19 to thereby rotate the same about its fulcrum and compress the spring 21, and with the slotted end of the lever 19 thus raised toward the notched end 32 of the platform 25, the fiow control element may be rotated to a position approximately perpendicular to the lever 19 with another leg thereof spanning the notch as shown in Fig. 5, whereupon the intermediate leg and the upwardly bent projection 36 of the lower leg will snap into and be retained by slots 37 formed in opposite sides of the lever bifurcations and the upper leg of the element will seat in the notch of the extension 32 upon release of pressure on the lever. The bracket 15 may then be applied to the handle 9 in an obvious manner with the aid of the clamp 16, and the container 11, with the conduit 17 secured to the nipple 14 thereof, may then be applied to the bracket 15 by slidably engaging the groove 24 with the platform 25. The lever 19 is then momentarily again tripped against the pressure of the spring 21 to position the conduit between the upper leg of the element 20 and the extension 32 of the platform 25, and the remaining length of the conduit 17 may be secured to the handle 9 by means of the spring clips 18 so that the discharge end of the conduit is located in the near vicinity of the polishing head, after which the container may be filled with liquid wax. The assemblage is then in condition for use and may be manipulated over the floor in an obvious manner by the manipulating portion 10 of the handle with desired quantities of liquid wax being supplied to the polishing head 8 by way of the conduit 17 upon periodic downward operation of the upper free end of the lever 19, the flow of wax through the conduit 17 being variable dependent upon the amount of pressure placed on the lever and the extent to which it is moved about its fulcrum.

From the foregoing detailed description, it is believed apparent that the present invention contemplates provi 'sion of a liquid wax dispenser which may be conveniently merchandised in the form of an accessory for quick and easy application to any commercially available floor polishers. The improved polish dispenser may be readily constructed at low cost essentially from plastics or the like, and the several parts may be readily assembled by a novice without the need for any special tools. By virtue of the location of the operating lever and the disposition of this lever within the space between the container 11 and the handle 9, the device may be readily operated in a most convenient manner from the manipulating end 10 of the handle, and the number of operating parts may be reduced to a minimum and are furthermore effectively protected from possible damage. The arrangement of the operating parts results in an extremely compact and durable structure which may be sold at relatively low cost, and the resultant unit has proven highly eflicient in actual operation. The improved accessory obviously eliminates considerable stooping or bending, and variable desired quantities of liquid wax may be applied to the floor immediately adjacent to the polishing head 8 of the polisher without splashing or flooding of the area to be polished.

It should be understood that it is not desired or intended to limit this invention to the exact details of construction of the improved liquid polish dispensing device, herein shown and described, since various modifications within the scope of the appended claims may occur to persons skilled in the art to which this invention pertains.
