Abstract

790,187. Micrometer gauge heads. ROCH SOC. A R.L., P. June 28, 1956 [Sept. 19, 1955], No. 20088/56. Class 106 (2). The graduated drum 1 of a micrometer head rotates on a sleeve 8, having an enlarged part 9 of the same external diameter as the drum and carrying a datum line or vernier 10, co-operating with the graduations 2 of the drum, and spring means 14 is provided which acts both axially and angularly to keep the part 9 in close contact with the graduated end of the drum and to prevent angular play by maintaining a pin 13 on the sleeve in contact with a guiding surface 17 on the body 5 of the micrometer. The head comprises a drum 1, graduated at its extremity and secured to a micrometric screw 3, which is engaged by the body 5. The sleeve 7 has a cylindrical part 8 inside the drum 1 and a projecting section 9, provided with a vernier or at least one datum line, and of the same external diameter as the drum 1. A sleeve 11, friction mounted on the body 5, has a longitudinal slot 12 in which is engaged the pin 13. This slot need not be rectilinear, as it may be arranged to counteract inaccuracies of the micrometric thread. Instead of the slot, the sleeve may be provided with a hole of any shape provided it has at least one longitudinal guiding surface.
