DEFINITION

Classification: 400/713

Attachment for shielding or screening record-medium or typewriter (e.g., against wind, etc.):

(under subclass 679) Subject matter wherein significance is attributed to a device used to cover a portion of the typewriter or the record-medium* or used to protect a portion of the record-medium.

(1) Note. One of the purposes of the shield or screen is to hide the typed material from curious or prying eyes looking over the typist's shoulder. Another purpose is to protect the typewriter of the record-medium from the effects of air moving in the vicinity of the typewriter.
