Title: Improvement in precision measuring instruments for gauging linear dimensions
IPC: G01B11/06
Filed: 1931-06-23
Abstract: 384,686. Linear-dimension gauges. AKTIEBOLAGET C. E. JOHANSSON, 46, Nygatan, Eskilstuna, Sweden. June 23, 1931, No. 18200. Convention date, June 28, 1930. [Class 106 (ii).] Relates to instruments of the type having a work support and a plunger movable relatively thereto the movements of which are transmitted to the shorter arm of a pivoted indicating pointer, and consists in providing on the instrument near the end of the long arm a microscope by means of which the indication of the pointer may be read off on a still further enlarged scale. The work support 1 may be raised and lowered relatively to the part 1b by means of a screwed shank 1a. Over the support is a measuring plunger 2 normally held up by a weak spring 3 bearing against a pin 4. The plunger is surrounded by a bearing sleeve which is held in a split bracket which serves to clamp it. The sleeve terminates in a bead 7 in which the lever 8 is pivoted on a pin 9. The short arm has a knife edge 10 bearing on the end of the plunger. Secured to the head 7 is an arm 11 to which one end of a spring 12 stronger than the spring 3 is attached, the other end being attached at 13 to the lever 8. Normally the spring 12 is held out of action by the tension on a wire 17 which is attached to the lever 8 and to a lever key 15 acted upon by a strong leaf spring 16. Secured to the baseplate 14 is a bracket 20 supporting in its split upper end a carrier 21 for a microscope 22. The arrangement is such that the end of the pointer moves in the vicinity of the optical axis of the microscope. Carried by the head is a bar 23 provided with a hole opposite the end 19 of the pointer through which light may be reflected from a mirror. On the front side of the part 23 is a box cover 25 to which is secured a short tube which protects the point 19 and objective of the microscope from being illuminated from the front side. The objective is adjusted by the usual knurled wheels 28 and hinge joint. Owing to the provision of a so-called ocular micrometer between the collective lens of the ocular and eye-lens of the ocular in that plane in which the image formed by the objective of the point 19 falls, the movement of the pointer may be observed as well as the graduations on the glass micrometer. A small scale may be provided on the end of the pointer in which case the micrometer may be graduated as a vernier, or the ocular may be provided with only a hair-cross. In use, a standard block is placed on the support 1 and the key 15 pressed down after which by turning the spindle 1a the point 19 is zeroized. The blocks to be gauged are then substituted and any departure noted.
