United States Patent 0 Des. 203,991 Patented Mar. 8, 1966 "ice COMBINED INSTRUMENT KNOB AND BACKING PLATE Perry H. Rosen, Portland, 0reg., assignor to Electro Scientific Industries, Inc., Portland, 0reg., a corporation of Oregon Continuation of design application Ser. No. 64,575, Apr. 3, 1961. This application Nov. 27, 1963, Ser. No. 77,600

Term of patent 14 years (Cl. D26-13) FIG. 1 is a plan view of a combined instrument knob and backing plate showing my new design;

FIG. 2 is a side elevation thereof viewed from the bottom in FIG. 1; and

FIG. 3 is a side elevation thereof viewed from the right or left in FIG. 1.

The outer annular area of the knob is transparent and is adapted to carry indicia formed on the underside thereof in a color substantially matching the color of the underlying backing plate, whereby the indicia are rendered only faintly discernible against that background. The backing plate carries an index section of keystone shape and of a color contrasting with the backing plate to highlight the indicium displayed over it. FIG. 1 is shaded to indicate contrasting colors.

This application is a continuation of my earlier application Serial No. D. 64,575, filed April 3, 1961, now abandoned.

I claim:

The ornamental design for a combined instrument knob and backing plate, as shown and described.
