Abstract: 735,922. Variable-speed gearing. STANDARD MOTOR CO., Ltd. March 9, 1954 [May 7, 1953], No. 12716/53. Class 80 (2). Three separate gear-type pumps 11, 12, 13 coupled to the spindles 54 of three planet pinions 29 are mounted in a casing 14 rotatable with a driving shaft 21. The three planet pinions 29 are in mesh respectively with three sun gears 24, 25, 26, the first of which is fast on the driven shaft 22 while the others are fast on sleeves 27, 28 rotatable on the driven shaft. These sleeves 27, 28 also carry gears meshing with double gears 31 and 39, 40 respectively on. a lay-shaft 32 which in turn mesh with gears 33, 35 connected to the driven shaft 22 through free-wheel devices 34, 36. The three pumps 11, 12, 13 are fed through inlet passages 18 from reservoirs 16, 17 in the casing 14 and deliver to a common central chamber 20 from which an outlet 44 is controlled by a balanced piston relief valve 45 loaded by a spring 51. The spring 51 is acted upon through a rod 50 by a centrifugal device 49 responsive to the speed of the driving shaft and casing 14 to increase its loading and close the relief outlet 44. With the engine idling and the driven shaft stationary the planets 29 rotate planet-fashion around the sungears 24, 25, 26. As the speed of the engine and casing 14 is increased the valve 45 tends to close to increase the pressure in chamber 20 and torque is thereby transmitted from all three pumps to the driven shaft. As the engine speed is further increased the pump driving the lowest speed train 26, 39, 40, 35 is slowed down relative to the casing and shaft 22 over-runs this train through free-wheel 36. On further increase of engine speed the next pump slows down and the associated train 25, 30, 31, 33 is also over-run. Finally the remaining pump associated with the sun 24 is stopped and a direct drive results.

IPC: F41G5/20
Abstract: 131,959. Dawson, Sir A. T., and Buckham, Sir G. T. June 7, 1918. Sights.-Relates to anti-aircraft ordnance provided with means for indicating a function, or for setting the sight in accordance with a function, which varies according to the angle of sight of the target. Such an indicator may comprise a tangent elevation dial and a pointer which is automatically moved across the face of the dial during the laying of the gun so as to occupy a position corresponding to the angle of sight. According to the invention, such indicators are adapted for guns on an unstable platform, such as a ship, by providing a pendulum or other device which nullifies the effect of the operations of the pointing- gear to keep the sight on the target when the platform tilts, the indicator moving in accordance with all the vertical angular movements of the gun relatively to the true horizontal plane. In the construction shown in Figs. 1 and 2, the indicator comprises a tangent elevation dial A' mounted on the carriage, and a pointer A<2> actuated by a Bowden wire a<1> from an arm B on the cradle trunnion. The rear end of the sheath A<3> of the Bowden wire is attached to a bracket a<4> on a pendulum C pivoted co-axially with the cradle trunnions and immersed in an oil bath C<1>. By this arrangement, when the platform tilts and the arm B is moved in keeping the sights on the target, the bracket a<4> is correspondingly moved by the pendulum and the pointer A<2> remains stationary. The Bowden-wire mechanism mav be replaced by a link and toothed segment gearing with a segment corresponding to the arm B. In the modification, shown in Fig. 6, both the dial A<1> and the pointer A<2> are mounted on the cradle, and the pendulum is directly connected to the pointer.

Patent GB-135041-A (GB)
IPC: B62D11/10
Abstract: 135,041. Caterpillar Tractors, Ltd., (Holt Manufacturing Co.). Jan. 18, 1919. Compulsory differential driving.-In double endlesstrack vehicles, two separate epicyclic driving gears are used, one for each track, in such a way that a certain element in each train of gearing is held stationary for straight running, but these two elements are rotated positively in opposite directicns by the motor when turning. Fig. 4 shows a section taken longitudinally of the vehicle, and Fig. 5 shows a transverse section. A transverse axle 48 extending right across the vehicle is driven by bevel gearing 46, 47 from a longitudinal shaft 44 and carries at its ends pin wheels 51, 52 forming the driving elements of the epicyclic gears. These pinions 51, 52 mesh with planet pinions 53 carried on spindles 55, 56 to which are also fixed smaller pinions 59 meshing with central wheels 60 which are held stationary for straight ahead running. The planet pinions are carried by the driven member, to which the track-driving sprocket 19 is secured. When turning, the central wheels 60 are rotated in either direction as required, but oppositely to one another. For this purpose, they are fixed on sleeves 49, 50, the inner ends of which carry bevel wheels 61, 61<1> meshing with a bevel wheel 62 carried by a vertical shaft 63 to which the large spur wheel 64 is fixed. A pinion 65 meshes with the spur wheel 64 and is adapted to be rotated in either directicn by friction gearing 67, 68, 69 by which its vertical shaft 66 may be connected to the longitudinal main driving-shaft 45. This gearing is operated by sliding the two wheels 68, 69 simultaneouely along their shaft, so that one or the other engages the wheel 67, this movement being effected by a lever 72 pivoted at its lower end to the gear casing and moved to and fro at its upper end by the rotation of the steering column 76 through a link connexion 74. The pinion 65 is locked in position for straight running by a finger 83 also shown in Figs. 6 and 7, carried on a pivoted locking member, which is also provided with an arm 85 on which a spring 84 acts so as to tend always to take the finger 83 out of engagement with the teeth of the pinion. The finger is put into engagement, when the friction gear operating lever 72 is in its mid position, by means of a lug 77 having inclined sides secured to the lever and co-operating with a pin 79 on an arm 80 also carried by the pivoted locking member.
