Abstract

369,899. Force-feed lubricating. CINCINNATI MILLING MACHINE CO., Cincinnati, Ohio, U.S.A.-(Assignees of Nenninger, L. F. ; 3525, Shaw Avenue, and Ernst, H. ; 3617, Edwards Road, both in Cincinnati, Ohio, U.S.A.) Sept. 25, 1930, No. 28744. Convention date, Sept. 28, 1929. Addition to 368,251, [Group XXII]. Drawings to Specification. [Class 12 (iii).] The machine described in the parent Specification is modified by the provision of hydraulic speed-changing mechanism, the hydraulic circuit being supplied by an oil pump working in conjunction with an accumulator which is so arranged that when the pressure in the accumulator has reached a predetermined maximum a valve is lifted which allows oil to flow to the lubricating system of the machine. When this occurs another valve is caused to seat and hold the pressure in the accumulator while the pump supplies the lubricating system.
