PATENT OFFICE.

MILBERT C. CLARKSON, OF KANSAS CITY, MISSOURI.

OUTSIDE WINDOW WASI-IEB.

Application filed. August 4, 1923. Serial No. 655,587.

To all whom it may concern.-

Be it known that I, hlrnnunr C. CLARK- SON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in an Outside Window Vasher, of which the following is a specification.

This invention relates to window cleaners and more particularly to an improved ap paratus especially designed for cleaning the outside surface of window-panes.

The primary object of the invention is to provide a manually operated apparatus which may be manipulated by an operator on the inside of a room so that the exterior surface of the window-pane may be cleaned, wiped or dried.

The invention has for another object a device which may be extended across the window sill of a window and supported on the window sill so that an operator may conveniently operate the movable part to cause the cleaning element to be moved over the exterior surface of the window-pane.

Other objects of the invention will appear upon consideration of the following detailed description and accompanying drawings in which:

Figure 1 is a perspective view of the apparatus constructed in accordance with my invention.

Figure 2 is a side elevation of the same, parts beingbroken away to more clearly disclose the mechanism.

Figure 3 is an end elevation.

Referring to the drawings by numerals, a supporting bar 1 is provlded to support the apparatus and is provided on one end with a clip 2 which is adapted to embrace the inner edge of the window sill so that the supporting bar will be properly held in position. The supporting bar 1 is long enough to extend considerably beyond the outside edge of the window sill as shown to advantage in the drawing and is equipped with a longitudinal slot 3 extending throughout the greater portion of the length of the supporting bar. The cleaning element 4, of the conventional type, is adapted to travel over the surface of the window-pane and obviously it may consist of a brush, wiper, or drying element. This element 4, is connected by a connecting rod 5 to the supporting bar 1 by a pin 6 which is adapted ,to travel in the longitudinal slot 3. This pin 6 is connected to one end of one of the operating rods 7 which extends in parallel relation to the supporting rod and across the window sill, the inner end being so disposed as to permit the operator to readily take hold of the member 7 when the device is to be operated. A complementary operating rod 8 is attached by a pin 9 to the connecting arm 5. at a point above the supporting rod or bar 1 so that two connections with operating members 7 and 8 are thus made with the connecting arm 5. The rod 8 is disposed above the rod 7 so that they may be moved longitudinally to impart movement to the arm 5.

IVhen the apparatus is in use it will be mounted 011 the window sill as shown in Figure 1 of the drawing and the operator may grasp the ends-of the rods 7 and S, and impart reciprocatory motion thereto thus swinging the ope-rating arm 5 and causing the pin 6 to move longitudinally in the slot 3 thus imparting motion to the upper end of the arm 5 whereby the cleaning element 4 will be moved over the surface of the glass on the outside of the window-pane.

Minor changes may be made in the details of construction without departing from the spiritof the invention or the scope of the claims hereunto appended.

What I claim is:

1. In an apparatus of the character described, a supporting bar, an operating arm, a cleaning element mounted on the end of the operating arm, the said supporting bar being equipped with a longitudinal slot, means connecting the operating arm to the said bar through the said longitudinal slot and a pair of operating rods connected to the operating arm whereby a reciprocatory motion may be imparted to the operating arm for readily moving the said cleaning element.

2. In an apparatus of the character described, a supporting bar having a longitudinal slot therein, an operating arm connected to said supporting bar through said longitudinal slot, a cleaning element attached to one end of said operating arm, a pair of spaced pins carried by said operating arm, a pair of operating rods arranged in parallel relation to each other and each having one end thereof connected to said pins whereby a reciprocatory motion may be imparted to said operating rods for moving said operating arm.

3, A window cleaner, comprising a sup.- portingbar, means for supporting said bar on a window sill, an operating arin, means for slidably connecting said operating arm to said supportingbar a cleaning element attached to said operating arm and adapted to engage the outside surface of a windowpane, and a pear of operating rod-s con.- nected to said operating arm and adapted 10 to be alternately reciprocated to impart a T.
