UNITED STATES PATENT OFFICE DESIGN FOR A VACUUM TUBE William Noel Eldred, San Mateo, Calif.
Application March 18, 1942, Serial No. 106,229
Term of patent 14 years To all whom it may concern:
Be it known that I, William Noel Eldred, a citizen of the United States of America and resident of San Mateo, county of San Mateo, State of California, have invented a new, original, and ornamental Design for a Vacuum Tube, of which the following is a specification, reference being had to the accompanying drawing, forming part thereof.
Fig. 1 is a side elevational View of a vacuum tube showing my new design.
Fig. 2 is a top plan View thereof.
The side of the vacuum tube opposite that shown in Fig. 1 is substantially the same as the side there shown.
The dominant features of my design reside in the vacuum tube disclosed having an envelope comprising a hemispherical top merging into a cylindrical body with a stem extending axially through the top, and having a plurality of divergent and downwardly sloping spoke-like members leading to the triode assembly caps which are centrally open at their tops, all as shown.
I claim:
The ornamental design for a vacuum tube, substantially as shown and described.
WILLIAM NOEL ELDRED.
