Title: Improvements in and relating to brakes
IPC: F16D65/54
Filed: 1946-05-15
Abstract: 612,032. Compensating for wear in shoe brakes. JOHNSTON, J. W. May 15, 1946, No. 14736. [Class 103 (i)] Automatic means for compensating for wear in shoe brakes comprises an arm having a lostmotion connection with a brake shoe and movable in a guide, and a spring-loaded wedge member which allows the arm to adjust itself to take up wear when the shoe is applied, but prevents its return movement so that the return movement of the shoe is limited to that permitted by the lost-motion connection. As shown, a pair of pivoted shoes b are applied by a pair of pistons working in a hydraulic cylinder f and are interconnected by a return spring f<SP>1</SP>. Two arms i, having pin-and-slot connections k, l with the shoes, extend through slots in lugs h on a plate g attached to the back-plate c, and are interconnected by a tension spring m. Also extending through the slots are two wedge members h interconnected by a tension spring o, these members allowing outward movement of the arms to take up wear, but preventing their inward movement so that the return movement of the shoes is limited to that allowed by the pin-and-slot connections. The members n may be provided with stops, which may be adjustable, and which limit their inward movement so that an indication is given when the brake linings are worn out. The shoes may be applied mechanically instead of hydraulically.

Abstract: 1,153,423. Rotary fluid-flow meters. BRITISH OXYGEN CO. Ltd. July 11, 1966 [April 9, 1965], No.15251/65. Heading F1F. A rotary meter for measuring the aggregate volume, or volume per unit time, of a gas flowing therethrough, includes a cylindrical stator 7 containing a rotor 1 fixed to a rotatable shaft 3, which is carried by struts 6 and connected to a pointer 9 by a gear-train 8, the rotor being made of corrugated sheet-metal, the corrugations being radially orientated to obviate flexing of the rotor during operation thereof. The gas enters a casing surrounding the stator through an inlet 10 and flows towards the rotor through a plurality of tangentially-orientated slots 11, which render the gaps within the stator turbulent so as to effect rotation of the rotor, the gas being ejected axially through a passage 12. An axially-movable tube 13 can be used to reduce the effective size of the slots 11 when the rate of flow of the gas is substantially less than normal, reduction in said size being effective to increase the angular velocity of the gas within the stator. Alternatively, the tube is rotatable relative to the stator and furnished with slots such that it can be used to partially obturate the slots 11. A dial associated with the pointer 9 has two scales corresponding to the positions of the said tube when it is fully retracted and when it is partially obturating the slots 11, respectively. The rotor may be furnished with ribs, to effect stiffening thereof, instead of the corrugations; and the tube 13 may be both axially movable and rotatable.

Abstract: 1,274,945. Grinding. HEALD MACHINE CO. 24 March, 1969 [1 April, 1968], No. 15326/69. Heading B3D. A grinding machine 10 comprises a base 11, a workhead 12 mounted on the base to support and rotate a workpiece 23 having a surface of revolution to be finished, e.g. a ball bearing race, a wheelhead 13 mounted on the base and having a rotatable spindle 21 carrying an abrasive wheel 22, and feed apparatus to bring about relative movement between the work-head and wheelhead to introduce the wheel to the workpiece with controlled force for performing a grinding operation to finish the surface. According to the invention means are provided for monitoring during grinding the relationship between the grinding force (F N ) exerted by the wheel on the workpiece normal to the surface of revolution and the grinding force (F T ) exerted by the wheel on the workpiece tangential to the surface of revolution and operative when the ratio of the tangential force to the normal force falls below a certain predetermined value to bring about renewal or dressing of the wheel surface. In the machine shown the workhead 12 is carried on a table 14 slidable longitudinally of the base 11 under the action of a fluid feed cylinder 19, and is driven by a belt 48 from a motor 47. The tangential force F T  exerted between the workpiece and wheel is measured either by a transducer 52 operated by the air pressure in a conduit 51 supplying air to an idler 49 over which the belt 48 passes, or by a meter 59 in one of the three-phase lines supplying the electric motor 47.  The wheelhead 13 is carried on a table 16 slidable transversely of the base 11 under the action of a fluid feed cylinder 18 supplied with fluid from a conduit 42. The normal force F N  between the wheel and workpiece is measured from the pressure in conduit 42 by a transducer 46. Electrical circuitry is provided in a main control which compares the ratio Á=F T /F N  with a predetermined value Á 0 . When Á becomes less than Á 0  a signal is generated either to a coil 55 which causes grinding to be interrupted and a tool 29 to dress the wheel 22, or to a coil 45 which opens a valve 44 to permit a pulse of fluid to the cylinder 18 thus urging the wheel 22 against the workpiece to crush-dress it.
