3 Claims.

The invention relates to cleaning apparatus, and more particularly to apparatus of this type utilizing the cleaning effect of swiftly moving air, and to attachments for such cleaning apparatus, whereby wax may be applied to a surface to be cleaned and after the application of wax the floor may be polished, while at the same time air is being drawn into the tool over theawaxed surface, thus drying such surface and picking up such particles of Wax and dirt as may be rubbed loose from the floor.

In designing the apparatus, it is my aimto utilize to a large extent standard and interchangeable parts, connections and the like, which are covered by my prior patents and pending applications, and which are included in what is known as the Air-Way System, the term Air- Way being covered by a registered trade-mark.

The present application is a continuation-inpart of my application Serial No.120',240,fi1ed May 7 1935.

'One of the objects of the present invention is to provide novel means for electrically heating the wax carried by the waxing attachment. IA

further object of the invention is to iprovide improved means for connecting andidisconnect- 1 ing the electric current which supplies the heating element. Still another object of the invention is toprovide means forautomatically'breaking the electrical connection as the cleaning tool equipped with the combined waxing and'polishing attachment is moved from the waxing to the polishing position.

Referring particularly'to the embodiment of the invention shown in Figs. 1-10 inclusive, A represents a floor tool of the Air-Way type and B a waxing and polishing attachment shown 40 shaded in contrast to the tool.

Thefloor tool may be of the type shown in Patent No. 2,017,770 to Replcgle and Queen, dated October 15, 1935, to which reference may be had for further details of construction, and the waxing. and polishing attachment is similar to that set forth in my copending application Serial No.

20,240, filed May 7, 1935, except that the waxing attachment is equipped with an electrical wax heating unit. The aforesaid application may be-referred to for details of construction com- .mon to the two.

able source of suction as the pipe [3. The nozzle is adapted to be reversed about the joint I l as indicated by Figs. 3 and 4;, for example. In the position shown in Fig. 3, the waxing attachment is in operative position with its face flush with the floor, while in Fig. 4, the polisher is in operative position and air may be drawn into the mouth of the nozzle together with rolled-up bits of wax, dirt, etc. In Fig. 1, the nozzle is shown connected to the suction-producing means of a portable type suction cleaner which may be of the general construction shown in my Reissue Patent No. 16,224, dated December 15, 1925. The reference numeral M denotes the fan motor cas ing. The polishing and waxing .attachment is shown in detail in Figs. 8, 9, and 10, the same being separated from the cleaner and the parts of the attachment separated one from another to show details of construction. The reference numeral i5 denotes a wax receiving trough which may be composed of sheet metal or any suitable material and which is provided with flexible attaching clips l6 which are adapted to fit over,

the top of the cleaner nozzle. l 7 denotes the polishing attachment or bar which is preferably of felt and which extends at an angle to the plane of the wax receiving trough. Extending from the ends of the trough [5 are members l8 having openings 59 therein to permit roller shanks of the cleaner nozzle to pass therethrough and to hold the attachment in position.

The numeral 20 denotes a suitable wax cake or bar shaped to fit into the trough I5, and 2!) denotes a paper covering which is partially or wholly removed from the wax before placing the same in the trough.

The heating unit is incorporated within a telescopic cover 2! which is adapted to fit over the wax cake and the trough 15. The cover is provided with a mesh facing 22 and the heating elements are shown as comprising coils 23 extending lengthwise of the unit. 'These coils are adapted to heat the wax cake and cause the'same to flow readily. 'The ends of the coils are provided with connectors 24 which are adapted to engage the heads of prongs 25, 25, to which the members 24 are attached. This attachment is.

shown clearly in Figs. 3, 4, 5, and 6. A socket member 26 is adapted to engage the prongsv 25, 25 and complete a circuit through the heating coils. When the socket is removed, the connection is broken. The socket 26 is connected to a conductor cord 2? which is supplied from any suitable source of current. A guide 28 is provided at the rear of the attachment and a further guide 29 is shown on the stub portion l 2.

In the arrangement shown in Figs. 5 and '7, the prongs 25 are shown fitted into the socket 26, the waxing attachment being in working position. The arrangement of parts is such that when the tool is reversed so as to place the nozzle in operative position, and the waxer in inoperative position, the current is automatically broken by separating the socket 26 from'the prongs 25, as indicated in Figs. 1 and 6. This is due to the fact that the member 29 through which the cord 27 passes is located at one side of the outlet pipe l2 and is accordingly closer to one end of the cleaner than to the other, and'to the further fact that the cord 2'? is only long'enough to permit the socket member to engage the prongs when these prongs are on the side adjacent the member 29 but is too short to reach the prongs when the tool is reversed so that they are on the side remote from the member 29.

In Fig. 1, the cord 2! is shown provided with a plug 60 at the end opposite the socket 26 which fits into an outlet 28 on the motor casing I l, the outlet being similar to that described in my Patent No. 1,983,566, datedDecember 11, 1934.

In Fig. 11, the attachment is shown applied to a cleaner of the Caddy type such as illustrated in my Patent No. 1,887,600, where the heater cord 27 is provided with a switch so and a separate cord 3i supplies the fan motor. In this construction it is intended that the heater unit be automatically cut off on reversal of the floor tool, just as in the embodiment previously described. In Fig. 12 there is shown a portion of a cleaner similar to that illustrated in Fig. 1, but the connecting cord 21 is of such length that on reversal of the floor tool, the plug 66 comes out of its socket. It will be understood that in all of these arrangements where there is automatic cut-oif of the heating means on reversal of the floor tool, it is necessary to manually replace the plug in its socket before the heating unit can again be employed.

It will be apparent that when current is applied to the heating unit, the wax is made softer and passes through the net cover between the loops of the heater. If desired, an attachment such as is shown in Fig. 14 could be provided hav ing a longitudinal slot to permit the wax to pass therethrough, the attachment serving to hold the heater unit in place and protect the net cover.

In Fig. 13, a modified form of wax applier is shown which may be used with conventional types of portable cleaners and may, in fact, be used with the Air-Way type as well. also be employed with conventional extension pipes from stationary or semi-portable plants. As shown, reference numeral 46 represents a heating unit including the longitudinal elements covered by a netting 4| and carried by a rectangular guide member 43 which tightly fits or telescopes over an inverted trough member 44 carrying a wax cake 45. The fit is sufilciently tight to hold the parts together and prevent accidental removal. The trough member 44 is provided with swinging bails 45 adapted to fit over the ends of a conventional nozzle 46, as shown in Figs. 15 and 16. The nozzle may be connected through a conduit 47 and hose 48 to any suitable source of suction. It will be noted that the attachment is readily removable and the trough 44 may be moved down under pressure applied to the nozzle as the wax is used up. The ends of the heating coil are provided with conductors 49, 49, leading from the heating unit to a connector 56, which in Figs. 15 and 16 is shown as detachably carried by the pipe 57. Current is supplied to the connector 50 through a cord 5| from any suitable source; .a switch 52 being preferably in the circuit. When the heating attachment is to be removed, the bails 45 and conductors 49 are easily separated from the cleaner which may then be used in the conventional manner. In Fig. 17 the electrical connector members are shown separated from the cleaner.

In Fig. 18, the attachment is shown applied to a portable type cleaner with the connector 56 detachably secured to a casing of a fan 01' the centrifugal type. It will be noted that the members l9 correspond with the members 24 shown in the first embodiment of the invention.

In Fig. 14 there is shown an attachment which may be employed as a floor polisher separate from the waxing and heating unit, or may be combined with the heating unit. As shown, the

It may a attachment comprises a trough-shaped member 53 having bails 54 adapted to fit over the nozzle head. A central slot 55 is provided in the bottom of the attachment. The lower face of the attachment is provided with felts 5B or other polishing members. Where the attachment is secured directly over a suction nozzle, the air enters the slot 55 and passes thence to the inlet mouth of the cleaner. In this manner, particles of dirt, wax, etc. may be removed from the floor during the polishing operation.

The attachment shown in Fig. 14 could be arranged to fit over the heating unit shown in Fig. 13, and would in such case, protect the net cov- 15 ering from direct contact with the floor. In such event, the attachment should preferably be made of a non-conducting material such as phenolic condensation products, hard fiber or the like. The slot 55 would then permit wax softened by the heating unit to pass therethrough.

The attachment shown in Fig. 14 could also be applied without material modification to the form of heating unit disclosed in the previously described embodiments of the invention, with the bails of the attachment fitting over the ends of the nozzle or over the roller supports.

It will also be apparent that a polishing unit such as shown in Fig. 14 could be used with any type of pressure head. In such event, the central slot might not be required.

Various modifications of the invention have been described in detail for the purpose of illustration, but it will be understood that further variations may be resorted to without departing from the spirit of the invention.

Under some circumstances it may be desirable to make the trough l5 and the member 2! (Fig. 2) of phenolic condensation products, hard fiber or other suitable material which is a non-conductor for electricity. Similarly, the corresponding members 44 and 43 of Fig. 13 may be of the same material.

I claim:

1. In combination with a reversible suction cleaner nozzle having an inlet mouth, an electrically heated waxing attachment for said nozzle having a surface adapted to engage the floor when the inlet mouth is in inoperative position, and means for automatically cutting off the current to said attachment as the nozzle is reversed to bring the inlet mouth into operative position.

2. An attachment as set forth in claim 1, having a polishing bar extending parallel with the inlet mouth.

3. In a device of the character described, a reversible head, an attachment therefor having an electrical wax heating portion and a floor polishing portion, adapted to be selectively applied to the floor, according to the position of said head, means for supplying current to said wax heating portion when the same is in waxing position, and means for automatically cutting oil the current when the device is turned to the polishing position.
