MARTIN BOURKE, OF YOUNGSTOWN, OHIO.
SPECIFICATION forming part of Letters Patent No. 635,462, dated October 24, 1899.
Application filed March 14, 1898. Serial No. 673,682. (No model.)
To all whom, it may concern:
Be it known that I, MARTIN BOURKE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in WVindow-Oleaners, of which the following is a specification,referenee being had therein to the accompanying drawings.
My invention relates to window-cleaners, and is substantially a device for wiping the window-panes dry of Water, at the same time clearing them of dirt and foreign substances.
I will first describe the details of my invention with the aid of the accompanying drawings, in which Figure 1 represents a perspectWe view of one of the window-cleaners as ready to be placed upon a long handle such as needed in using it. Fig. 2 is a vertical section of Fig. 1 upon its mid-line, and Fig. 3 is a longitudinal sectional view of a part of Fig. 1 at right angles to Fig. 2.
In the several views the same numeral always indicates the same part.
1 represents a split tube of resilient metal, extending into the radial wings 2 and 3, the latter being about half the width of the former. Between these wings 2 and 3 is inserted the strip of rubber fabric 4 and secured in position by means of the rivets 5 or other desirable manner. The fabric 4 projects beyond the wings a sufficient distance to form a convenient wiping-surface 6 for use.
A metal handle-socket 7 is soldered to the mid-portion of the tube 1. To brace it in its position therewith, a triangularly-shaped plate of metal 8 is entered into the slot 9 of the handle-socket 7 and into the slot 10 of the tube 1 and duly soldered into position. To further strengthen the same, the edge 11 of the plate 8 is bent over to form a hook, which, engaging the edge of the slot, adds materially to the rigidity of the construction after the parts are soldered together.
The operation of my invention is as follows: The socket being placed upon a handle of desirable length and secured thereon, the rubber is brought in contact with the windowpane and the latter is wiped therewith, usually in a downward direction. The lower wing 3, as has been already noted, is made somewhat narrower than the upper wing to materially add to the pliability of the rubber wiping-surface and to increase the efficiency thereof.
Having thus fully described my invention MARTIN BOURKE.
