WINDS??? CLEANER.

Application filed Jilly 2, 1921.

T 0. all whom it may concern Be it known that 1,.V1oron VIOLA, a subject of the Kin of Italy, and a resident of the borough of anhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Window Cleaners, 5f which the following is aspecification'.

This invention relates to improvements in window cleaners.

An object of this invention is to provide a device which simultaneously cleans both sides of a window.

Another object of this invention is to provide such a device with cleaning elements adapted to work into the corners of a windew and which may be readily adjusted to occup convenient positions.

A urther object of this invention is to provide in such a device novel means for keeping the cleaning elements always in contact wlth the window when the device is in use.

These and other objects including ease in operation, efiiciency and effectiveness are attained by the novel construction and arrangement of parts hereinafter described and shown in the accompanying drawing, forming an essential part golf the disclosure, and in which 2-- Figure 1 illustrates the application of the invention to a window.

Figure 2 is a side elevation of the device.

Fi re 3 is a front elevation of same (arms partly broken away).

Figure 4: is' a front view of the top portion thereof showing the cleaning elements turned through an angle.

In general the device comprises two flexible arms mountedat one of their extremities on a block. These arms are provided at their other extremities with removable and adjustable cleaning elements, the latter being adapted to contact with both sides of a window pane when applied, by means of the flexure of the arms and a tension bolt. Means fully described below, are provided to regulate the lateral pressure of the cleaning elements and facilitate the latter remaining in contact with the window during operation.

Referrin to the drawings in detail nu block substantially but having slightly ta lar in sha e rec ngu p mounted the tapered ends upon which are Serial lilo. aeeooe.

flexible arms 12. These arms made preferably from suitable wood and shaped to give the desired flexibility are secured at one of their ends in the tapered ends of block 11 by means of the bolts 13 and when thus secured slightly converge. By separately at taching the arms to the block the device is prevented from splitting when the former are spread outwardly as would be the case if the arms and block were formed of one piece. Block 11 is made of sufiicientlength so as'to permit the arms being passed over the frame of the window and any protru sions on the latter.

Disposed at the upper ends of arms 12 are the cleaning elements 14. These cleaning elements are comprised of preferably square or rectangular shaped cleats 15 having soft pads 18 made of felt or other suitable substance adhesivelyattached to their outer surfaces the contours of which are similar to the cleats but of larger area so that they extend beyond the edges of the cleats.

Cleats 15 are provided with arcuated slots 17 adapted to engage the bolts 18, the slots being countersunk so that the heads of the bolts will not protrude from the surface ofthe cleats and cause the pads to bulge.

Disposed between cleaning elements 14 and arms 12' are the washers. 19 and helical springs 20 the function of which will be explained below.

Bolts 18 are made of suiiicient length to extend through washers 19, springs 20 and the perforations inarms 12 and to engage wing nuts 21. I

Disposed over block 11 and parallel thereto is a tension bolt. 22 which passes through perforations in arms 12, the threaded end of which engages a wing nut 23' adapted to regulate the tension on the arms. The urpose of this bolt is to keep the arms rom spreading which might be caused by a change in the condition of the arms such as warping, etc.

Two sets of the elements 14 are provided, one for simultaneously washing both'sides of the window "and the other for simultaneously drying same. These elements may be interchanged very easily.

To use the device the pads of cleaning elements 14 are moistened and secured to arms 12. Arms 12 are then adjusted by means of tension bolt 22 until the pads 16 touch each other at their outer surfaces. By manually spreading arms 12 apart sufiicient space sprin s 20.

may be obtained between the cleaning elements to clear the frame of the window.

The pressure of pads 16 of the cleaning elements 14: on bothsurfaces of the window is regulated by the manipulation of wing nuts 21', and the co-operative action of Thus the pressure of the cleaning e ements u on the window may, within certain limitations, be regulated independently of the arms so that in case the latter for some reason fails ,-to cause sufiicient pressure to be maintained the necessary additional pressure may be produced in the manner stated above.

:lhe cleaning elements are constructed in such a manner that they fit into the corners of the window. Being provided with slots 17 they may be turned at any convenient angle soas to fit into the corners of diamond shaped windows and the like.

After the window has been washed the wet cleaning elements are removed and dry ones substituted therefor to complete the cleaning operation.

From the'foregoing it is manifest that an efficient anduseful device for simultaneously cleaning both sides of a window has been produced. The device being operated from theinside eliminates the hazards usually en" countered by one when cleaning windows.

While certain referred embodiments of this device have em shown and described,

I it will be understood that changes in the and surface pad, and resilient means for regulating the pressure of said elements upon an intervening object.

2 An article of manufacture for cleaning windows comprising a mount, a pair of flexible arms attached at one of their ends to said mount, a tension bolt engaging said armsdirectly above said mount, a pair of opposed cleaning elements removably secured to said arms at the latters free ends,

each of said elements consisting of a cleat and surface pad, and resilient means for regulating the pressure of said elements upon an intervening object.

' 3. An article ofmanufacture for simultaneously cleaning both surfaces of a window comprising a block, a pair of flexible arms attached at one of their ends to said block, a tension bolt adapted to engage said arms directly above said block,da (pair of opposed cleaning elements provi I with surface pads adapted to normally contact with each other and arcuated slots, means engaging in said slots for removably securing said cleaning elements to said arms, and resilient similar shape, said cleats being provided with arcuated slots and means engaging in said slots for adjustably sec'uringthe cleaning elements to said arms at any desired angle limited by the slot.

5 Anarticle of manufacture for simultaneously cleaning both surfaces of a window comprising a tapered block, a pair of flexible arms each having one end attached to said block, atension bolt cooperating with said arms directly above said block, opposed cleaning elements, each comprising a rectangular cleat and a yieldable surface pad of similar shape, said cleats being provided with arcuated slots, means engaging in said slots for adjustably securing the cleaning elements to said arms at any desired angle limited by the slot, and means disposed between said arms and said cleats for facilitating said pads being held in contact with the adjoining surfaces of an intervening object.

Signed at New York in the county New York and State of New York this 25th day of June, A. D. 1921.
