Abstract
415,879. Internal-grinding machines. CHURCHILL MACHINE TOOL CO., Ltd., Broadheath, Manchester, and ASBRIDGE, H. H., Reigate, Moss Lane, Aston-on-Mersey. July 19, 1933, No. 20362. [Class 60.] In an internal-grinding machine of the type in which the work table a is traversed to operative position by hydraulic means, which then hold it against a reciprocating stop c which gives the table short and rapid to-and-fro movements during grinding, the stop c is mounted on a spring-loaded slide c<1> in a carrier d pivoted at e and operated by power means which, in the form shown, comprise a crank f and connecting-rod g. A loaded release valve r<1> allows the piston of the hydraulic operating cylinder to be moved by the oscillating stop c. As the table a moves towards the operative position the stop c rides up an incline h on a bracket i, the upward movement causing it to operate, through a projecting portion j, a valve which diminishes the supply of fluid to the operating cylinder to lessen the speed of the table.
