Abstract

407,825. Hydraulic transmission of power. VOGTLANDISCHE MASCHINENFABRIK VORM. J. C. & H. DIETRICH AKT.-GES., Plauen, Vogtland, Germany. March 14, 1933, No. 7705. Convention date, March 29, 1932. [Class 69 (ii).] In hydraulically-operated machine tools, a pipe 28 leading to a hydraulic work-clamping device is fitted with an air vessel 30 and a valve 27, the latter being connected to a choke valve 16 in the oil return line from the cylinder 13; the arrangement is such that as soon as the valve 16 is open the valve 27 is closed. The Specification as open to inspection under Sect. 91 comprises also the use of a choke pump in parallel with the valve 16 and preferably mechanically connected to the supply pump 3, air-removal pipes 33 with adjustable closures 35, a drip plate 37 visible through an observation opening 36, and coarse and fine adjustment means at X for limiting the stroke of the bed 19. This subject-matter does not appear in the Specification as accepted.
