4 Claims.

This invention relates to surface coatin especially the coating of floors and furniture and more particularly the waxing thereof.

The principal object of this invention is the provision of a device to facilitate the preliminary deposit on a surface of a fluid which is to be thereafter spread and/or polished.

A further object of the invention is the production of a device of the type specified by which the initial or preliminary deposit of a fluid to a surface to be coated may be accomplished by a simple manual motion of the device used to spread and/or polish the fluid after being preliminarily deposited.

A further object of the invention is the production of a device of the type specified which will include a receptacle for coating fluid of such construction that it may be detachably connected to the spreading and/r polishing device and which may be caused to deposit more fluid, as required, by placing the manipulating handle thereof in a position other than that in which it is held during the spreading and/or polishing.

Other objects and advantages will appear as the description of the particular physical embodiment selected to illustrate the invention progresses and the novel features will be particularly pointed out in the appended claims.

In describing the particular physical embodiment selected to illustrate the invention,,reference will be had to the accompanying drawings and several views thereon, in which like characters of reference designate like parts throughout the several views, and in which:

Fig. 1 is a side elevational view of aspreading and/ or polishing mop with my invention attached thereto in combination therewith; Fig. 2 is a cross sectional View on the plane indicated by the line II--II of Fig. 1, viewed in the direction of the arrows at the ends of the line; Fig. 3 is an en larged sectional view of the valve and valve-;

actuating mechanism of my device; Fig. 4 is a cross sectional view on the plane indicated by the line IV-IV of Fig. 3, viewed in the direction'of the arrows at the ends of the line; Fig. 5 isa side elevational View of the mechanism as shown by Fig. 3 but with the parts in a different position;

Fig. 6 is a view similar to Fig. 3 but of a modified form of valve and valve-actuating means and Fig. '7 is a plan view of a metal strip used in my invention.

Numeral I designates the textile or other suitable or appropriate material of an ordinary or usual fluid distributing and/or polishing mop.

2 designates any usual or ordinary block or attachment means for the mop material I.

l and 2 together constitute the head of the mop.

3 designates any usual or ordinary manipu-.

to be inserted .and frictionally held'in a cavity ;5

treated and/or may also be used as a rubber to bring the fluid which has been distributed to the desired consistency or brilliancy. Such devices are in common-use and are'quite universal inperforming the operation 'known as waxing.

In waxing a surface, it is first necessary to apply the fluid waxto one or several places and to then distribute the same and perhaps do alot of mopping in order to bring the wax to a polish. It is quite customary to have a receptacle for the wax which is separate and apart from "the distributing and/or polishing mop, but this necessitates the use of both hands and the inconvenient carrying about of a receptacle containing fluid waxing compound. It further requires, es-

pecially when waxing floors, of stooping overalall) most constantly in order to apply the wax at the proper place.

My invention contemplates carrying the Wax receptacle right on the distributing or polishing mop and the application thereof to "the surface being treated, as a floor, by an unusual movement given to the handle of the mop.

6 designates a hollow container. This container may be of any usual or desired configuration. I prefer the ordinary and well-known rectangular hollow metal can. This can may be provided with any suitable or appropriate filling opening. I prefer to form an orifice 1 in one end thereof as is quite usual, and surround this orifice by an outstanding metal nozzle 8 attached to the can by an outstanding flange '9 as by soldering or welding. The nozzle 8 is preferably formed with a rolled or pressed helical thread Ill, as is quite This construction gives a good free openthe desired fluid, such as polishing wax.

In order to position the container 6 as I desire, I provide mop handle attaching means. This may take several forms, but I prefer a single =2 strip 32. This strip is made of sheet metal of such gauge that it may be quite easily bent by the fingers from a flat condition to the condition as shown in Fig. 2. The attaching strip, as shown by Fig. 7, is made of a piece of flat sheet metal 33 cut through along the lines 34 and 35 to provide attaching tabs and pairs of aligning orifices as at any suitable means as a wing nut 46.

36 and 31 to provide bolt receptacles. The tabs formed by cutting along the lines 34 and 35 are either welded or soldered or otherwise suitably attached to the side, as 38, of the container 6, and the wholestrip 33, as dispensed to the customers would lie flat along the side 38. The customer, upon Securing the container 6, would raise the unattached ends thereof into the position as' shown in Fig. 2 around the mophandle as 3, and then secure the container in place by passing a threaded bolt 39 through one of the pair of mating orifices 36 and 31, securing the same by If the mop handle is reasonably small, the holes 31 would be used. By loosening the-inner nut 40, the handle with relation to the container may be so adjusted that the container is in just such position that the abutment 26 will just properl contact the surface being treated, as 3!, when the handle 3 israised to the vertical position, as shown in Fig. 1.

The nozzle, such as 3, hereinbefore described, is usually covered with a cap which is likewise formed with a helical thread so that it may be screwed on to the nozzle.

H, but my cap carries my valve and valveactuating means. I pierce, preferably in three places, the top or outside surface E2 of the cap, that is, referring to Fig. 4, at l3, l4 and I5, and I place a rubber disk or annulus E6 on the underside or inside of the cap having, preferably, a single orifice I! therethrough. With such a cap, if 'the container 6 were turned with the cap directed downwardly, the fluid within the container would run out, so I provide a valve means to retain the fluid in the container until such time as-I desire to have it issue.

a The valve means of my invention includes a valve disk l8 adapted to seat against the disk l6 overlapping the edges of the orifice 51. When the valve disk I8 is in such position, as shown in Fig. 3, no fluid may issue from the container 6. In order to properly position and hold the valve disk |8, I form it with an orifice l9. Through this orifice 191 place an eyelet it. Next I place a washer 2 I over the eyelet and then I spin or force over the edge of the eyelet 22 so that it will lie flat against the metal washer 2i. I then force a round stem 23 into the through bore 24 of the eyelet. This stem 23 is merely a drive fit into the eyelet, but hold sufficiently to maintain the stem in place.

When the disk l8, preferably made of soft rubher, is seated firmly againstthe disk l6, also preferabl made of soft rubber, no fluid may issue from the container 6. In order to retain the valve disk l8 in such position I thread the outer end of the valve stem 23, as at 25, and on to this screw thread I screw an abutment 26. I also interpose a helical spring 2'! between the abutment 26 and a stirrup or U-shaped member 28 extending outwardly from the cap I l. The stirrup 28 serves not only to guide the valve stem 23, as there is an orifice or through bore 29 therethrough for that purpose, but it also enables me to keep the end of the helical spring 2! away from the openings 14 and I 5, so that they are unobstructed.

It will be obvious that if pressure is applied to abutment 26 in the proper direction, the valve disk 3 will be moved from its seat and fluid in the container may flow out through the orifices l4 and Hi. If it is desired to entirely prevent any flow, the abutment 26 is screwed on to the valve stem 23 until the convolutions of the helical I, likewise, use a cap spring 21 are in contact, as shown in Fig. 5. Under such conditions the valve disk I8 is forceably drawn to the seat I6 and pressure upon the abutment 26 cannot force the disk from its seat. This is the position of the parts when the device is not in use. When the device is in use the abutment 26 is screwed outwardly on the stem 23, so that the convolutions of the spring 2'! are somewhat as'shown in Fig. 3, so that a pressure upon abutment 26 in the proper direction will open the valve.

The abutment 26 may well be of any ordinary and suitable material, but I prefer to make it of soft rubber, and to prevent undue wear upon the thread, I prefer to have a metal insert 30 through which the stem passes and which will take the wear of the thread.

The container being positioned upon the handle 3, as shown in Fig. 1, if the handle is moved to the vertical line position, as shown in Fig. l, the

' abutment 26 will contact the floor or other surface being treated, and force the valve disks l8 upwardly thereby allowing fluid to flow from within the container through the openings M and 15 to drop upon the surface being treated or the mop M. The handle 3 ma be raised to the vertical position as often as desired and as much fluid from the container 6 may be dropped upon the surface at one time or at various times as seems to be desirable. The material dropped upon the surface 3! may then be spread by 'returning the handle to its usual operating position, as shown in the inclined position in Fig. l, and distributed b the operative end I of the mop and/or polished as may be desired.

It will be noted, by reference to Fig. 2, that the strip 32 has been attached to the side of container 6 to one side of the center thereof. By this c0nstruction not only may the cam be moved up and down on the handle 3, but the cam may be rotated about the handle 3 as a center to more readily adjust the position of the cam and the relation of the abutment 26 to the surface worked upon and the mop head.

In Fig. 6 I have shown a somewhat modified form of. my invention in that the abutment member 4| corresponding to abutment 26, remains fixed on the stem 23 and the spring 21 has its convolutions brought close together, as shown in Fig. 5, by screwing the nut 42 upwardly as shown in Fig. 6.

From the hereinbefore given description it will be understood that I have provided a combination of distributing and/or polishing mop with a carried liquid container and provided means whereby, by a single manual motion, fluid may be caused to issue from the container to flow upon a surface to be treated and/or polished, which fluid is treated and/or polished by a movement of the mop holding the handle in the usual position and that, when the device is not in use, a simple motion, such as screwing a nut onto a threaded stem, serves to tightly close the container having the fluid therein so that it may be safely placed away until it isnext desired to use it, and that my device may be applied to and adjusted on the usual handle of the usual mop by the very simple device of bending a strip thereabout and threading a wing nut onto the end of a threaded bolt.

Although I have particularly described one particular physical embodiment of my invention, nevertheless, I desire to have it understood that the form selected is merely illustrative and does not exhaust the possible physical embodiments of the idea of means underlying my invention.

What I claim as new and desire to secure by Letters Patent is:
