Abstract
660,126. Securing knobs to spindles. WALKER, CROSWELLER & CO., Ltd., and BARKER, C. L. May 16, 1949 [May 21, 1948], No. 13754/48. Class 80 (ii) [Also in Group XXIX] A thermostatiic mixing device comprises a one-piece, stationary, cylindrical spigot 13 mounted on the crown of a boss formed on the base of the casing and having for each fluid inlet 1, 2, in the base a passage 18, 19, communicating with outlets in the spigot periphery, and a ported sleeve valve 22 surrounding the spigot and rotated by a thermal unit 36, 38 in the mixing chamber b. Each spigot passage opens into a system of several outlets in the same plane, e.g. three spaced 120 degrees apart, and the outlets in the several systems are staggered with respect to each other. The thermal unit comprises two bimetallic coils joined at the outer ends at 37, the inner end of one, 38, being connected to a bush 39 which is fixed to an adjusting spindle 30 by a pin 40 which shears under excessive torsional force, while the inner end of the other, 36, is connected to a spider 32 rotatably mounted on the spindle and having pins 34 engaging grooves in the sleeve valve. The outer end of the spindle is adjustably connected to a knob 55 for setting the mixture temperature. Leakage from the mixing chamber is prevented by the abutment, due to the spring 44, of the bush 39 on the casing and by the gland 43, the spindle passing through and being secured by a pin 49 to an annulus 45 and also carrying a pin 47 retaining the washer 46 and spring 44. Serrations on the periphery of the annulus engage internal serrations on the knob which is secured by a screw 56. In a modification the spindle carries a single pin which engages a groove in a central boss of the annulus and retains the spring in an annular groove in the annulus. In another arrangement the pin engages grooves in the walls of a cup-shaped annulus and secures a spring retaining boss on the spindle. In a further modification, the pin retains the spring in the groove while the annulus has a key fitting a key-way on the spindle.
