Tarney, 205 E. Market St., San Antonio, Tex. Filed Jan. 23, 1961, Ser. No. 84,262 3 Claims. (Cl. 15-103) This invention relates to a motor driven device for cleaning windows or similar surfaces, eliminating the use of flowing water.

An important object of the invention is to provide a motor operated window cleaning device including a hand manipulated frame providing a support for a motor driven roller having window wiping blades disposed longitudinally thereof, which blades are moved into contact with the window being cleaned, removing foreign matter and cleaning the windows.

Another object of the invention is to provide a motor operated cleaning device of this character having a roller on which a roll of paper is placed together with means for feeding the paper from the roll to a position for contact by the window wiping blades, maintaining the blades clean at all times.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

FIGURE 1 is a side elevational view of a window cleaning apparatus constructed in accordance with the in- Ventlon.

FIGURE 2 is a side elevational view thereof, one side wall of the housing of the device having been removed.

FIGURE 3 is a sectional view taken on line 33 of FIGURE 2.

FIGURE 4 is a transverse sectional view taken on line 44 of FIGURE 3.

FIGURE 5 is a fragmental sectional view taken on line 5-5 of FIGURE 3.

FIGURE 6 is a sectional view taken on line 6-6 of FIGURE 4.

Referring to the drawings in detail, the frame of the apparatus is indicated generally by the reference character 5, and includes side walls 6, rear end wall 7 and on open front. 8.

As better shown by FIGURE 2 of the drawings, the forward edges of the open front 8 are inclined at 9, the side walls being connected by connecting rods 10 on which the spacing tubes 11 are mounted, the ends of the spacing tubes contacting the walls 6 holding them in proper spaced relation with respect to each other.

Mounted adjacent to the open front end of the frame 5 and so disposed that portions thereof will operate beyond the ends of the side walls of the open end of the frame, is a roller 12 which is provided with wiping blades 13 that are disposed in spaced relation with respect to each other and arranged longitudinally of the roller 12.

The shaft on which the roller 12 operates is indicated by the reference character 14 and has its ends disposed in bearings formed in the side walls 6, one end of the shaft 14 extending beyond one side wall 6 where it supports the pulley 15 over which a belt 16 operates, the belt 16 operating over a pulley 17 secured on the shaft 18 which shaft 18 has its ends also operating in bearings formed in the side walls 6, one end of the shaft being supplied with a pulley 19 which is enlarged as,

compared the pulley 17.

A belt 20 operates over pulley 19, the belt 20 also operating over a small pulley 21 secured on one end of the motor shaft 22.

The motor is indicated by the reference character 23, and is mounted on the motor supporting bar 24 that is supported between the side walls 6, as shown by FIG- URE 3 of the drawings.

Mounted within the frame 5, near the bottom thereof, are rollers 25 and feed roller 26 which are so arranged with respect to each other that a sheet of paper indicated by the reference character 27 unrolled from the roll 28, is fed therebetween, the feed roller 26 being operated by belt 28 operating over a pulley 29 secured at one end of the shaft 30 in which the roller 26 is mounted.

As better shown by FIGURE 6 of the drawings, the belt 218' also operates over a pulley 31 secured to one end of the shaft 32 on which the gear 33 is secured, the gear 33 meshing with a small pinion 34 mounted on one end of the shaft 35 to which the substantially large gear 36 is secured, the gear 36 meshing with the substantially small pinion 37 mounted on one end of the shaft 14 on which the roller 12 is mounted.

The side walls 6 are provided with vertical elongated slots 38 disposed directly opposite to each other, which slots receive the shaft 39 on which the roll of paper 28 is mounted, the shaft 39 being held in position at the bottom of the slots 38, by means of the spring latch arms 46 pivotally mounted exteriorly of the frame, the free ends of the latch arms being hooked over the ends of the shaft 39 normally holding the shaft in position. Coiled springs 41 are provided for moving the spring latch arms to their active holding positions.

It might be further stated that the shaft on which the roll of paper 28 is mounted may thus be readily and easily removed and replaced when it is desired to replace the roll of paper.

The reference character 42 indicates a hollow roller mounted between the side walls 6 of the frame 5 the roller 42 being constructed of porous or absorbing material so that cleaning fluid contained therein may penetrate to the outer surface of the roller 42 to be picked up by the blades 13 of the roller 12 and transferred to the window surface B being cleaned.

The blades 13 also have a wiping contact with the strip of paper movable over rollers 43 and 44 with the result that the blades 13' are maintained clean at all times.

A handle 45 extends from the bottom of the frame 5 and afiords means for effecting manipulation of the apparatus over a window surface being cleaned.

What is claimed is:

1. A Window cleaning apparatus comprising a frame embodying side Walls, a rear wall and an open front, a motor mounted between the the side walls, a rotary roller mounted within said frame adjacent to said open front, flexible wiping blades disposed longitudinally of said rotary roller operating through said open front in wiping contact with a window, against which said frame is held, a hollow porous roller in which liquid is contained saturating said hollow roller mounted between said side walls for wiping contact by said blades supplying moisture to said blades, a roller on which a roll of cleaning paper is mounted within said frame for wiping contact by said blades maintaining said blades clean.

2. A window cleaning apparatus comprising a frame having an open front and a motor mounted with said frame, a wiping roller mounted at the open front end of said frame wiping blades extending longitudinally of said wiping roller operating through said open end of said frame in wiping contact with the window being cleaned, a moisture supplying porous roller mounted Within said frame, over which said blade moves in Wiping contact therewith, means for supplying a strip of paper within the path of travel of said blades with which said blades contact cleaning foreign material from said blades, 'andimeans for operatively associating said motor with said rollers, operating said rollers.

3. A window cleaning apparatus comprising a frame having an open front and a motor mounted with said frame, a Wiping roller mounted at the open front end of said frame wiping blades, extending longitudinally of said Wiping roller operating through said open end of said frame in wiping contact with the window being cleaned, a moisture supplying porous roller mounted within said frame, over which said blade moves in wiping contact therewith, means for supplying a strip of paper within the path of travel of said blades with which said blades contact cleaning foreign material from said blades, and means for operatively associating said motor with said rollers, operating said rollers, reduction gearing for gradually feeding said paper strip into the path of travel of said blades for removing moisture and foreign matter from said blades. i
