Abstract

729,033. Momentary contact switches. HYDROPRESS, Inc. Nov. 27, 1950 [Jan. 20, 1950], No. 28958/50. Class 38 (5) In a switch operated by the passage of members such as pipes 31 of varying sizes, the pipe in its passage momentarily deflects a flexible finger 29, consisting e.g. of a spiral spring, and causes the tilting of a disc 24 which in turn causes the reciprocation of a rod 13 which. operates a micro or other switch 14. The rod 13 is biased downwards by a spring 18 and its upward movement is limited by a washer 21 on the rod. The lower position of the spring 18 is determined by a washer 20 placed in a selected annular cut 22 to determine the strength of the spring. Specification 729,034, [Group XIX], is referred to.
