Title: Improved apparatus for operating the brakes of railway and other vehicles and for other purposes
IPC: B61H13/04
Filed: 1921-03-12
Abstract: 173,991. Tinson, W. H., (Saccaggio, P. C.). March 12, 1921. Addition to 155,868. Force-transmitting mechanism.-Relates to brake and other mechanism of the kind in which the leverage automatically increases when, in the case of brakes, the tension in a pull-rod reaches a certain value consequent upon the application of the blocks to the wheels and in particular to the mechanism described with reference to Figs. 17 and 18 of the parent Specification. The disc member 60, which is keyed upon the operating- shaft S and which is engaged by the pawl 9 during the first part of the operation, is itself provided with teeth 62 which engage with the gear-wheel 49 after the disengagement of the pawl 9. When therefore the shaft S is turned to apply the brakes, the projection 10 of the pawl 9 being at first held in engagement with the recess in the disc 60 by the spring 12, the lever 48, freely mounted on the shaft S, and pull-rod P move as one with the disc. When the blocks are in contact with the wheels and the force applied increases sufficiently to cause disengagement of the pawl 9 against the action of the spring 12, the teeth 62 engage with the gearwheel 49 and the further movement of the lever 48 is effected by the crawling of the wheel 49 along the fixed rack 50. To ensure the proper meshing of the teeth 62 on the disc 60 with those on the wheel 49, there is provided on the disc 60 a first tooth 64 which is adapted to yield radially against a spring 66 and thus to pass a tooth of the wheel 49 if necessary to avoid jamming of the wheel and disc. To lock the mechanism in the operated position, the disc 60 may have teeth 63 for engagement with a pawl 71 which may be counterweighted so that it disengages when relieved of the pressure on it by slight movement of the shaft S. Grooves and holes 73, 75 may be formed in the parts 60, 48 to lighten them.

Abstract: 635,240. Casings; cylinders. PESCARA, R. P. March 28, 1947, No. 8467. Convention date, June 10, 1943. [Class 7 (ii)] In an internal-combustion engine having a plurality of in-line cylinders, each cylinder having overhead inlet and exhaust valves actuated through push rods from a single camshaft mounted near the lower end of the cylinders, and in which the stems of the valves of each cylinder are located approximately in a transverse plane with respect to the longitudinal axis of the engine, the cylinder head or heads are so constructed that the cooling water passages for cooling the valve seats and guides are confined to welldefined portions of the cylinder head so that there are left regions of the cylinder head or heads accessible from the side and having a height less than the height of the portions in which the sparking plug or plugs of each cylinder are mounted, each of the regions extending to or communicating by a passage with the side of the cylinder head to allow the free escape of oil, water or other liquid therefrom, and there being a cover or covers detachably secured to the cylinder head or heads which enclose the rocker arms, their pivotal axes and the external extremities of the valves and of which the shape as seen in plan view corresponds to the periphery of the portions of the cylinder head or heads carrying the cooling water passages. The valve cover for a four cylinder in-line overhead valve engine is shaped as indicated by its gasket 226 so that. sparking plugs 222, 322, 422 and the. ends of the top of the cylinder head are left uncovered. A region 235 in which the sparking plugs 322 and 422 are situated only communicates with the outside through the passage 250. The height of the cylinder head in the uncovered parts 234 and 235 is just sufficient to accommodate. the water jacket. The sparking plugs, one or two of which may be used in each cylinder, are inclined to the cylinder axis so that the electrodes are positioned near the centre of each combustion chamber in the end wall of which latter are situated an inlet and an exhaust valve. When two sparking plugs are used in each cylinder the inlet valve rocker arm is located in a plane perpendicular to the plane containing the axes of the two plugs and midway between these axes. In a modification for two cylinder engines, the covers thus formed may be used with each pair of a four, six or eight cylinder engine.
