Abstract
406,420. Spring weighing machines. SALTER & CO., Ltd., G., and BACHE, E. W., 144, High Street, West Bromwich. Nov. 2, 1932, Nos. 30817 and 30818. [Class 143.] A spring weighing-machine, which may be combined with a lifting-jack, comprises a platform disposed above and supported by Belleville washers, the yielding of which is transmitted to a pointer. In the construction shown in Fig. 1, the platform 1 is secured to a depending stem 2 which is guided vertically by balls 11 and by the opening in the cover 13. The weight is transmitted through balls 8 to the Belleville washers 4, 5 and thence through balls 9 to the base 3. Vertical movement of the platform is transmitted to the pointer 14 through a lever 15, a link 25, sector 27 and pinion. A similar apparatus is combined with a lifting jack for use particularly with vehicles, as shown in Fig. 3. When the jack is raised, tho weight of an axle is transmitted through a non-rotating screwed stem 31 to the rotatable screwed nut or sleeve 2 and thence through balls 8, 9 and Belleville washers 4, 5 to the stand 3. The screw 31 is held against rotation by keys 38 in the cover 43 and the sleeve 2 is rotated by gearing 35, 36 from a shaft 37, the teeth being shaped so as to remain in engagement during vertical movement of the sleeve. A lever 39, 41 transmits vertical movements of the sleeve to the pointer 14 to indicate the weight supported.
