Abstract: 771,018. Weighing-apparatus. AKTIEBOLAGET STATHMOS. Jan. 12, 1955 [Sept. 21, 1954], No. 997/55. Class 143. In weight recording apparatus, wherein a type disc marked in minor order weight units is positioned according to the load, a type bar marked in major order units is (1) manually set for different weighing capacities (2) automatically set by the arrangement of type disc feeling members if the load exceeds the manual capacity setting by at least one major order unit. The type disc 1 has 100 two-figure markings 3 and is mounted on an axle 7 with an associated sector 6 with decimal markings 4. The type bar 9 is mounted in a holder 10 manually adjustable through linkage 12, 13 for different weighing capacities set on a lever 11. Ten pins 17, spring mounted in a holder 16, constitute an arcuate vernier scale such that the pressing of holder 16 against disc 1 by means of a handle 18 on a shaft 19 causes one of the pins to engage in one of a series of 100 holes 15 in the disc corresponding to each of the two-figure numbers thereon. A cam 20 on shaft 19, which normally acts on a spring- loaded lever 22 and a link 23 to keep sector 6 fixed in position, is actuated by turning handle 18 to permit clockwise sector movement until a feeling-arm 24 on the sector engages with the pin 17 that has entered one of the holes 15. In this position one of the sector markings indicates in the stamping position the decimal corresponding to the engaged pin. Further movement of handle 18 is communicated to a feeling-arm 30 of a bell-crank 29, 30, through linkage 25, 26, 27, 28. If the decimal is between 1 and 9, arm 30 is checked by a pin 34 in holder 16 and the movement of a link 31 connected to arm 30 is taken up in a slot 31a, while any further movement of handle 18 is taken up in spring 28. If, however, the disc 1 has rotated through a complete revolution, so that the decimal is zero, pin 34 engages in a hole (not shown) in the disc and arm 30 now moves further until checked by a stop 35. The resulting additional movement of link 31 is communicated through a lever 32 and a pin 33 to the bar 9, so that the latter moves relative to holder 10 to indicate an extra major order unit. In order that the markings of disc 1 and bar 9 may always be oppositely positioned, a link 14 mounted on lever 22 allows movements of sector 6 to be communicated to bar-holder 10 through lever 13. With the type set, operation of handle 18 through linkage 36, 37, 38, 39 causes a stamping pad 41 to press against.the type. After printing, a spring 42 pulls the mechanism back to its initial position on release of the handle. In modifications, Figs. 5-8 (not shown) (1) the disc has raised arcuate bars of different radii corresponding to separate ranges of 100 minor order twofigure numbers, each bar having a corresponding feeling pin. The feeling arm may be stepped or plain for coaction with a composite stepped pin or separate stepped pins respectively (2) the holes in the disc may be replaced by recesses in the edge of the disc so that the feeling pins can move in the plane of the disc for direct adjustment of the type bar without the intermediate feeling arm (3) the raised bars may be replaced by stepped radii round the periphery of the disc.
