Title: Improvements relating to gyroscopic apparatus
IPC: G01C19/44
Filed: 1932-02-10
Abstract: 393,695. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.-(Assignees of Carlson, B. G. ; 42-05, Layton Street, Elmhurst, New York, U.S.A.) Feb. 10, 1932, No. 4006. Convention date, Feb. 10, 1931. [Class 97 (iii).] A gyro-vertical for aircraft comprises a substantially non-pendulous gyroscope and light pendulous shutters pivoted adjacent air jet orifices in the gyro casing and adapted upon relative inclination of the gyro and one or more of the shutters to control air jets causing an erecting torque to reduce the inclination of the gyro directly. In the form shown the rotor 19 is mounted on a vertical axis in a casing 9 pivoting about a horizontal axis 15-16 in a gimbal 12, which in turn pivots about a perpendicular horizontal axis in the outer casing 1. Air is drawn from the casing 1 and air for driving the rotor enters through an aperture in the casing 1 and is supplied to jets 17, 18 in the casing 9 through hollow trunnions and the hollow gimbal ring 12. The air used for driving the rotor escapes from the casing 9 through main ports 21<1>, 21, 22<1> and 22, arranged in a downward extension 51 of the casing 9 and directed parallel to the gimbal axes in both directions. The ports are partially covered by pendulous shutters 23, 23<1>, 24, 24<1> (not shown) pivoted to the extension 51, opposite pairs being preferably secured to common pivot shafts. Upon inclination of the gyro one of the ports is covered whilst the opposite port is uncovered causing an unbalanced reaction which provides a torque for erecting the gyro. To diminish the effect of continued accelerations, the erecting torque is decreased upon large relative inclinations of the gyro and shutters by the provision of auxiliary ports, e.g. 26, Fig. 4, which become uncovered when the main ports opposite them become uncovered. Alternatively only main ports may be provided and the shutters so shaped that after covering the ports they partly uncover them again upon further inclination. In a further alternative the shutter uncovers firstly the main port and secondly an aperture permitting the air to escape more freely, thus decreasing the torque. The shutters instead of being pivoted may be fixed to flat springs each secured at one end to the extension 51 and carrying at the other end a weight. In a modification the shutters may operate in conjunction with pairs of driving jets spaced above and below the plane of symmetry of the rotor. A bar adapted to form an artificial horizon may be connected to a link pivoted on the gimbal 12 and moved by a crank arm fixed to the pivotal axis of the casing 9.

Abstract: 510,898. Automatic firearms. CESKA ZBROJOVKA AKCIOVA SPOLECNOST V. PRAZE. Feb. 14, 1938, No. 4534. Convention date, Feb. 18, 1937. [Class 119] The rear closure member 1 of the breech casing of an automatic firearm is locked in position by a transversely swinging member 7 which is coupled by a bayonet joint to the closure member and which engages a groove 11 in the fixed part of the firearm. The member 1 houses a breechblock carrier buffer spring 23 mounted on a rod 26 which passes freely through a breechblock carrier 5, but has a cross-piece 27 so that by turning the rod 26 through approximately 180 degrees, when the carrier is at the end of its stroke, the carrier is coupled to the rod 26 and can be withdrawn therewith. The rod 26 has a flat end 24 which slides in a slot 25 in the member 1. Accordingly, the member 7 may be turned to unlock the closure member 1 and withdraw it together with the breech mechanism, after which the cover 6 can be removed. If the member 7 is turned when the breech is. closed, the member 1 is removed without being accompanied by the breech-block carrier and in this case recoil springs bearing at one end against the breech-block carrier and at the other end against shoulders on pins in the member 1, are de-tensioned and may be removed. The ends of the recoil spring pins engage, one with a notch on the member 7 to prevent unintentional rotation thereof, and the other with an arcuate recess in the member 7 to prevent separation of the member 7 from the closure 1 by excess movement of the member 7. The safety catch (not shown) for the trigger is interconnected by a spindle 34, Fig. 4, with the member 7 so that unlocking rotation of the member 7 is prevented unless the gun is placed at safety by the lever 35.
