Title: Safety radiator pressure caps
IPC: F01P11/02
Filed: 1961-01-19
Abstract: 951,801. Valves. STANT MANUFACTURING CO. Inc. Jan. 19, 1961 [July 11, 1960], No. 2278/61. Heading F2V. [Also in Division F4] A safety pressure cap 17 for a radiator filler heck 10 includes a cap body 18, a pressure valve 20 supported from the cap body, spring means 32 resiliently resisting movement of the valve 20 towards the body 18, and an actuator 43 which is supported on and movable relative to the body 18 to shift the valve 20 towards the body 18 against the action of the spring means 32. The arrangement permits release of the pressure in an I.C. engine cooling system before starting to remove the radiator closure cap. When the lever 43 is in the position of Fig. 1 the hot water or steam under pressure is sealed within the radiator tank 13 by the gasket 21<SP>1</SP> engaging the seat 14 due to the spring 32 confined between the diaphragm 19 and pan 26. When it is desired to remove the cap 17 from the filler neck 10, the lever 43 is shifted to the position shown in Fig. 3. Thus the cam face 45 is brought into engagement with the disc 41 and the pin 42 is moved upwardly from its position of Fig. 1 to that of Fig. 3, thereby elevating the stem 35 and yoke'33. The yoke 33 carries with it the valve assembly 20 to lift the gasket 21<SP>1</SP> bodily free of the seat 14, thus placing the interior of the cooling system into communication with the atmosphere through the vent port 15 and overflow tube 16. A spring-pressed valve 23 (Fig. 1) is adapted to open to relieve any vacuum which may arise within the cooling system, the gasket 39 prevents escape of vapour or liquid through the passage made by stem 35. The lever 43 may be so constructed that it stands at 45 degrees when holding the valve in pressure-releasing position.

Jan. 24, 1928, Gear wheels, grinding and trueing teeth of; trueing and balancing rotating tools.-In a machine for grinding toothed gears and the like wherein a grinding wheel h is mounted on a reciprocating slide g while the gear blank d is mounted on an indexable spindle c and is fed transversely on a slide b to give the required tooth depth, the gear blank is interconnected with the mechanism for feeding a trueing mechanism i up to the grinding-wheel so that an indication is given to the machine attendant of the effective relative feed movement between the grinding wheel and the work. The feed mechanism for the trueing tools i comprise a slide o fed by screw and nut gearing n, m, operated from a handwheel z through a shaft j and worm gearing k. The shaft also drives through a worm p an annular disc r carrying an index mark. A graduated disc s mounted coaxially with the disc r is rotated through gearing from a shaft u connected by bevel gearing v to the feed spindle w of the work-slide. the spindle being rotated from a hand wheel 2 through gearing x. Thus when in operation the wheel z is operated to feed the trimming tools to the wheel, the disc r is moved relatively to the disc s by an amount corresponding to'the reduction in diameter of the grinding-wheel produced by the trimming operation. This reduction is compensated by moving the work-slide by means of the wheel 2, until the markings of the discs r, s are brought to their original relative positions. Movement in excess of this represents the useful feed imparted to the workpiece and is indicated on the disc s.

Abstract: 461,459. Foot-arch supports. FIKANY, J. A. Jan. 27, 1936, No. 2495. [Class 17 (ii)] A foot-arch support comprises two curved members 4, 10 which are longitudinally adjustable in relation to one another about an average intermediate position to increase or decrease the effective length of the arch. The height of the arch is increased by this longitudinal adjustment from the intermediate position, e.g. by forming the members 4, 10 with co-operating cam faces 4<a>, 14 which causes one member to move heightwise relatively to the other when these faces abut when the length is decreased. The members 4, 10 are, respectively, in the shape of a channel and a tongue fitting therein, and the member 10 carries at its forward end a widened ovular support 12 for the metatarsal arch of the foot. The members are provided with interengaging serrated faces or pins and holes to adjust them in longitudinal position, screw or other clamping means retaining them in the desired location. The support is placed between the inner and outer soles, being secured in position by tacks driven through holes in its rear end 6, and a flap is formed in the insole to give access to the clamping means by which the support is held in adjusted position.
