Title: A safety device for rotary machines with thrust bearings
IPC: F16C32/06
Filed: 1951-04-12
Abstract: 701,530. Linear-dimension gauges. LICENTIA PATENT-VERWALTUNGS GES. April 12, 1951 [Oct. 1, 1948], No. 8532/51. Class 106 (2) [Also in Groups XXIV, XXVI and XXXIV] The amount of wear in the thrust bearing of a rotary machine is measured by the variations of oil pressure in a pipe which passes through the thrust bearing casing and discharges on to a side face of the thrust bearing disc and so near to the disc that a throttle effect is produced which varies with the distance between the disc and the discharge orifice. An oil pipe e passes through the casing d of a thrust bearing and has its discharge end disposed at a short distance s from one side face of the thrust disc a. The oil pressure in the pipe e which varies with variations of the distance s acts on a spring loaded piston f which actuates a release device g of an emergency shut off device. An orifice plate h maintains as far as possible the supply pressure of the oil constant. To enable the operator to check the axial displacement of the thrust disc, a pressure gauge i is connected to the pipe e between the orifice h and the discharge end. Since the gauge i only gives correct measurement of the displacement of the thrust disc when the pressure before the orifice h is constant, a second pressure gauge l is provided. The readings of these two gauges can be used in conjunction with a graph to give an accurate measurement of the wear in the bearing. Specification 693,021 is referred to.

Title: An improved clock
IPC: G04B15/00
Filed: 1936-03-27
Abstract: 466,371. Clocks. MEATH, R. LE N. BRABAZON, EARL OF, and BOWELL, G. B. March 27, 1936, No. 9095. [Class 139] A clock is driven by a continuously running substantially constant speed motor, for example, an electric motor, through a clutch or a frictional or other slipping device, so that the motor may still rotate when the escapement is locked during each pendulum vibration. The motor pinion 1, Fig. 1, frictionally drives a wheel 2 rigid with the shaft 3 of the escape member 4. In the position shown the pendulum 6 is swinging to the right, and the scape member 4 is locked by the pallet 5 until the pendulum swings clear when the member 4 impulses the pendulum and rotates at constant speed until it again engages the pallet 5 just before the pendulum has reached the position shown in its next swing to the right, the drive 1, 2 slipping during the time the member 4 is locked. The pallet 5 may alternatively, be mounted on a gravity arm for impulsing the pendulum. In another construction, the pinion 1 positively drives the wheel 2 and shaft 3, Figs. 3, 4, the scape member 4 and a pinion 12 geared to the dialwork being freely mounted on the arbor 3 and driven thereby through a coil spring clutch 13. As the pendulum 6 moves to the left it picks up the gravity arm 8 pivoted at 9 unlocking the scape member 4 from pallet 5 whereupon the member 4 is rotated by wheel 2 about three-quarters of a revolution by the time the pendulum, now moving to the right, passes through the position shown. The gravity arm therefore descends to the stop 10 thus impulsing the pendulum after which the lifting pin 11 on the member 4 resets the gravity arm 8 through arm 15 as the scape member 4 engages the pallet 5 disengaging the coil-spring clutch. The lifting pin 11 may alternatively be fixed to part 12, Fig. 4.
