Application filed June 30, 1916. Serial No. 106,791.

To all whom it may concern:

Be it known that I, ENOOH M. VoomLn, a citizen of the United States, residing at (lhieago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Cleaners, of which the following is a specification.

This invention relates to window cleaners, and its purpose is to provide an improved device of this kind which may be conveniently operated for effecting a thorough cleaning of Windows, or other like objects. The principal object of the invention is to provide a powerdriven window cleaner having a movable washing element and a movable drying element. A further object is to provide a window cleaner having a movable washing element in combination with improved means for supplying water or other washing fluid thereto. Still another ob ject is to provide a window cleaner having a heated drying element. A further feature relates tothe provision of a rotatable washing element and a rotatable drying element, in combination with improved'means for actuating these elements and controlling the operation thereof. Another object to provide an improved construction and arrangement of parts in a power-driven window cleaner.

These and other objects of the invention will appear more clearly from the following specification, taken in connection with the accompanying drawings, in which embodiments of the invention are illustrated. In the drawings Figure 1 is a front elevation of the preferred form of my improved window cleaner, showing vertical sections through certain parts of the apparatus.

Fig. 12 is a side elevation, taken at right angles to the View shown in Fig. 9, showing certain parts in section.

Referring to Figs. 1 to 8, inclusive, of the drawings, 1t will be seen that the embodiment of my invention illustrated therein comprises a conical washing element 15 and a conical heating and drying element 16, both of which are arranged to rotate by means hereinafter to be described, and which are adapted to be used in succession on the window, or other object, being cleaned in order to effect a washin and drying thereof. The washing mem er 15 comprises a conical supporting member 17, which is preferably constructed of metal, such as brass or the like, this supporting member comprising a base 17 which is attached to a supporting bracket 18, by which the washing member is carried. A hollow shaft 19 is attached to or formed integrally with the bracket 18, and extends downwardly therefrom in alinement with the vertical axis of the conical member 17. This shaft is hollow, for a purpose to be described, and is journaled in the spaced apart bearings 20. A groove pulley 21 is fixed on the shaft 19 between the bearings 20, and the rotation of this pulley by suitable driving means effects the rotation of the washing member for cleaning purposes. Suitable collars or washers 22 are mounted on the shaft 19 beneath the lowermost bearing 20, and a suitable nut 23 threadedly engages the lower end of the shaft. The conical supporting member 17 of the washin element is surrounded and covered b a c causing or washing member 25, whici may preferably be formed of woolen cloth, felt, or the like, and which is arranged to fit closely the member 17 and is adapted to be held in fixed position thereon by means of a split clamping ring 26 passing through a suitable hem which is provided around the lower edge of the member 25, this clamping ring being of lesser diameter than the base of the supporting member.

The member 17 is provided near its upper end with a transversely extending tube 28, which communicates with a downwardly extending tube 29. This tube forms a continuation of and may be in fact a part of the shaft 19, previously described, so that a communication is formed through said shaft to a pipe 30 which extends upwardly into the lower end of the shaft and forms a rotative engagement therewith. Suitable packing may be placed in the chamber 23 of the nut 23, in order to effect a fluidtight connection between the shaft 19 and the pipe 30, through which water or other washing fluid is supplied to the tube 29, and thence through the tube 28 to the outer surface of the supporting member 17, where the water or other fluid moistens the cleansing or washing member 25.

The pipe 30 leads upwardly from the lower end of the shaft 19 and communicates with a small chamber 32, which is formed in a supporting member 33. This chamber, in turn, communicates with a tank 34, which is carried by the member 33 and which is adapted to contain water or other washing fluid. The ends of this tank are preferably shaped to conform to the contours of the washing and drying elements, as shown, for instance, in Figs. 4, 5, and 6, and the side walls 34 conver e upwardly, being spaced inwardly from p anes which are tangent to the washing and drying elements. The upper wall of the tank is provided with a detachable cap 34", through which the fluid may be passed into the tank.

1118 supportin member 33 and the bearings 20, previous y described, are carried by suitable brackets 33 and 20, respectively, which are secured to or formed integrally with the casin of an electric motor 35. The shaft 36 of t e motor extends vertically from the casing 35 and carries at its upper end a small water wheel or vane 37, which is located in the chamber 32 and adapted to rotate therein when the motor is in operation. A suitable packing chamber 38 is formed in the mem er 33 around the shaft 36, this chamber being closed by a packing nut 39, whereby a. fluid-tight connection is made between the shaft 36 and the member 33. It will be seen that the chamber 32 and the water wheel 37 form a centrifugal pump,

by means of which fluid in the tank 34 is driven through the pipe 30 to the tubes 29 and 28, through which the fluid passes to the outer surface of the member 17 of the washing element.

A doublegrooved driving pulley 40 is fixed upon the shaft 36 between the nut 39 and the bearin 35 of the motor casing, and a flexiblc hot 41 passes around this pulley and around the pulley 21, previously described, to effect the rotation of the washing element when the motor is in operation. A second flexible belt 42 passes around the other groove of the pulley 40, and thence around another pulley 43 which is fixed on a vertical shaft 44, journaled in the bearings 45 carried by suitable brackets 45, which are attached to or formed integrally with the motor casing. A collar 46 is fixed on the lower end of the shaft 44, and the upper end of the shaft is fixed to or formed integrally with a supporting bracket 47 which is at tached to the base 48" of a conical support ing member 48, which forms a part of the drying element 16. By means of this construction it will be apparent that the operation of the motor efi'ects the notation of the drying element at the same time that the washing element is operated. A drying member or cloth 49, formed preferably of flannel, or the like, seats upon and closely fits the conical supporting member 48, and is secured thereon by means of a clamping ring 50, which is similar to the clamping ring 26 previously referred to.

The member 48 is hollow, and has mounted therein a heating member 51, which comprises a porcelain or other insulating supporting post 52, having formed on the base thereof the inwardly projecting lugs 52, which are secured to the base 48 of the conical member 48 and to the arms of the bracket 47 by means of screws 52 or the like. A ring 53 is secured to the base 48* by screws 53, and the ring is in turn secured to the conical walls of the member 48, thus permitting access to the interior of the drying member when desired. The porcelain supporting post 52 is preferably in the form of a truncated cone, and is provided on its peripheral surface with a spiral groove 54 w ieh forms a seat for the electrical resistance element or wire 55, which is adapted to effect the heating of the drying element upon the passe e of a suitable electric current therethroug The ends of this resistance Wire pass through suitable bushings 56 mounted in the base 48 of the member 48 and the extremities of this resistance element are connected to the metallic contact rings 57 which are mounted on and insulated from the under side of the, su porting bracket 48 concentrically with the axis of the shaft 44. An arm 59 extends outwardly from the upper bearing 45, and

However, instead of and drying elements simultaneously, sit or element may be employed alone by supporting the pole 68 in such a position as to causeone element only toengage the surface of the "window. this way the Window may be washed in one operation, and then dried by a suceeeding movement of the rying element over the surface thereof.' It will be seen that the heating member of the drying element. ma

be controlled by the switch v78 independ ently of the operation of the motor, sothat it is unnecessary to maintain the dryingclement in a highly heated conditionwhen it is in operation, or the dryingelement may be used without being heated if desired. The heating member of the dryingelement operates to heat the interior of the member 48, so that a highly heated chamber is rorided within the drying element, and this heat is transmitted throughthe'walls of the member 48 to the drying cloth 49, thereby serving to prevent amundue accumulation of moisture in the cloth'and. also toslice a substantially dry condition, fii'igwill be apparent that at any time during theeleaning operation the cloths or o or members 25 and 49 may be removed if theybeeome soiled or unduly saturatedwith; moisture, and new washing'or drying cloths, or the like, can be placed on the conical members 17 and 48 after releasing thesplit clamping rings 26 and 50. The particular advantage th form of cleaning device'described V hin and'drymg elements may be manipulated to contact with the corners and other inaccessible parts of the dew surface in order to effect cleaning of the entire surface of the winow.

with an outer through the centrally. located mg element by the centrifugal force a con- Y venient position on the pole 68,.so that the device may beuconveniently controlled by Referring to Figs. 9 to 12, inclusive, of the drawings, it will be see that the modified form of my invention comprises a washing element .80 and a drying element 81, which are diflerent in form from the corresponding' elements embodied in the reviously described form of my invention. The washing element 80 comprises a metallic supporting member 82, which is hollow and circular inform, being provided wall 82%, an inner wall 82', and an annular inclined wall 82. The wall 82 is preferably formed integrally with the wall 82. Projecting inwardly from the innerisurface of the wall 82 are lugs 82 and the outer wall 82 is then attached to the lugs by means of screws, or other suitable means. The washing member 83, preferably a cloth of suitable material, is seated on the outer plane surface 82", and its edges extend around the annular inclined wall 82 being secured; in position by a detachable split clamping ring 84. "The inner Wall 82"0515 the supporting member is fixed to the hub and the rim of a relatively large gear 85. This gear is fixed upon the reduced part 85 of a supplementary hub 85", which journa1ed;.up0n the stub shaft ,86 projecting from theT-upper enlarged part 87 of the bracket 88 carried by or formed integrally with the casin of an electric motor '89. The horizontally extending shaft of the motor has secured thereon a driving pinion 90, which meshes withthe gear 85., thereby causing the rotation of the washing element when the motor isin operation. A lock nut 91 engages the threaded extremity of the reduced part 85 of the supplementary hub, and serves to maintain the inner wall 82" and the gear85 securely fixed upon the supplementary hub 85. other nut 92 engages the threaded extremity of the stub shaft 86, andmaintains the hub and gear on said shaft. It will be apparent that the outer Wall of the washing member may be assembled in position on the supporting lugs 82 after the nuts 91 and 92 have been assembled in position.

The sankes for washing fluid is mounted upon the enlarged part 87 of the bracket 88, and the upper wallof this tank is prosided with a detanhaible cap 93 which may be removed to permit the filling of the tank end of the latter,
