W NDO L NE Applieation filed. February 29, 1924.

To all whom it may concern;

Be it known that I, THOMAS J. KI FEATHER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in lVindow Cleaners, of which the following is a specification.

This invention relates to window cleaning and washing devices and more particularly to a novel and improved construction whereby the outer surface of a window may be cleaned from the inside of a room.

One of the objects of my invention is to provide a window cleaning mechanism constructed and arranged whereby the operator may raise and lower the cleaning and wiping element from the inside so asto engage the entire surface of the pane of glass to be cleaned.

Another object of my invention is to provide a. window cleaning and wiping device of the character above set forth which is GX- tremely simple in construction, highly eflicient in operation and use, extremely light and otherwise practical, easily operated and inexpensive to manufacture.

In order to more fully understand my invention, reference is had to the accompanying drawings, showing a preferred embodiment thereof, wherein;

Figure 1 is a view showing the application of my invention.

Figure 2 is a side view of the mechanism in its relation to the window and sash.

Figure 8 is a view, partly in section showing the relation of the wiper or carrying block to the supporting standards.

Figure 4 is a plan view showing the relation of the wiper and block to the supporting standard.

Figure 5 is a further view of the standard and carrier or block with the cleaning ele ment attached.

Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, 5 designates the main standard which is of a length substantially of the height of a window sash. Connected to the bottom of the standard 5, I have provided a circular connecting bar 6, which is adapted to rest on the window sill, it being at right angles to the supporting standard 5 above referred to. An operating arm 7, having a handle 8 is connected to the opposite end of the bar 6 Serial No. 696,023.

and at right angles thereto so that the arm 7 lies in parallelism with the support 5. The window frame or sash 9 and the window pane 10, whichvmay be raised and lowered,

thus permits the support or standard 5 to be positioned on the outside so that the operator may actuate the arm and the handle 8 across the outer surface of the window.

It will be seen that the bar or standard 5 is shown as square in cross section and has mounted thereon a block 11 which is adapted to slide on the standard 5. The said block 11 is further provided with opposed grooves 13 through which a cord 14: passes, one end of the pulley being knotted as at 15 whereby the block may be raised and lowered. The cord 14 extends over a pulley wheel 16 at the top of the standard 5 and is trained. over a second pulley wheel 17 at the bottom of said standard. The opposite end of the cord passes through an eye 17 adjacent the bottom of the arm 7 and is further provided with a knob 18 whereby the said pulley may be actuated and thus raise the block 11. This construction also permits the block to be raised somewhat beyond the top of the standard 5 thus allowing for the use of the device on windows of various sizes. In practice the knob 18 is of a weight to counterbalance the block 11 and hangs as a dead weight.

Reference being had particularly to Figures 2 and 4 of the drawings, it will be seen that I have provided a wiper 19 which is preferably of rubber, the latter being hingedly connected as at 20 to one face of the block 11. The block is also formed so as to permit the attachment of a cloth or rubbing element 20 secured by a strap 21 to the rear face of said block whereby the cloth or rubbing element may be attached over the rubbing member 19 when the same is not in use. Under normal conditions, it will be seen that the weight of the block will cause it to be held at the bottom of the standard 5 and that by simply actuating the pulley 14, the block and wiper or rubbing element may be raised to the desired position with respect to the window. The handle 8 permits of a sweeping motion of the wiper or rubbing element across the outer surface of the window whereby the entire operation of cleaning the window may be'easily accomplished in a comparatively short time and from the inside of the room as above shown.

While I have illustrated and described my ICU invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction. or otherwise altering the arrangement of the correlated parts without departing from the spirit Off the invention or the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is A window cleaning device of the class described comprising a vertical standard, an

15 operating arm connected to the lower end of the standard and at right angles thereto, a block slidable on the standard, a hinged wiping" element carried by the block, said block having opposed inner grooves, pulley wheels at the top and bottom of the standard, a cord connected at one end to the block and trained over said pulley wheels and through the grooves, the opposite end of the cord extending below the operating arm whereby the block may be raised or lowered during the swinging movement of the operating arm.

In testimony whereof I atlix my signature.
