Opinion

SHOWALTER, Circuit Judge.

The complainant sues for the infringement of letters patent of the United States, Ho-. 270,522, issued January 9, 1883, to the American Bell Telephone Company, assignee of the applicant, one Thomas A. Watson. As stated in the specification, the subject-matter of the invention is “An Improvement in Telephone Switches.” I quote further from the specification: •

“The invention consists In the use of a single lever in connection with a telephone and a call circuit and proper contact points, in such manner that a movement of the lever in one direction disconnects the call circuit from the main line, brings in the hand telephone and secondary circuit of the transmitter, and at the same time completes the primary local circuit of the transmitter, while a move[574]*574ment of tlie lever in the other direction cuts out the hand telephone and secondary circuit of the transmitter, and restores the call circuit. The invention consists further in making the lever operative as a switch, as aforesaid, in the form of a hook supporting the hand telephone, and combining therewith a spring, in such manner that taking the hand telephone from the hook causes the lever automatically to disconnect the call circuit, bring in the hand telephone, and secondary circuit of the transmitter, and complete the local primary circuit; while hanging the hand telephone upon'the hook causes the lever to automatically cut out the hand telephone and secondary circuit of the transmitter, and restore the call circuit.”
