Application May 4, 1938, Serial No. 76,968

Term of patent 7 years To all whom it may concern:

Be it known that I, William Fader, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented a new, original, and ornamental Design for a Window Ventilator, of which the following is a specification, reference being had to the accompanying drawing, forming part thereof.

Figure 1 is a front elevational view of a window ventilator showing my new design with the inside member in partially extended position,

Figure 2 is an end; and,

Figure 3 is an edge view thereof.

The characteristic features of my design as shown reside in a pair of elements which when assembled form a ventilator having a continuous central panel surrounded by acontinuous flat margin with a V-shaped groove separating the panel and margin, wherein the panel is formed with spaced groups of louvers separated by vertical ornamental indentations which indentations are substantially equal in height to each group of louvers and extend substantially from one groove to the opposite groove.

I claim:

The ornamental design for a Window ventilator, as shown and described.
