Abstract

742,570. Change-speed control. GENERAL MOTORS CORPORATION. June 16, 1953 [June 25, 1952], No. 26135/54. Divided out of 742,552. Drawings to Specification. Class 80(2) The subject-matter is an abridged version of the main Specification 742,552, but the claims are directed to the front brake overrun control valve 27 (see abridgment of main Specification) through which brake-apply pressure passes to the front brake servo, the valve being actuated by the same fluid pressure which is supplied to the front brake servo for brake release, to exhaust the brake-apply pressure from the servo; and to the restrictor-valve 28 which delays front brake application during downshift to permit engine speed to rise. Specifications 522,881 and 728,461 also are referred to.
