Abstract: 299,377. Schmidt, R., and Seitz-Werke Ges., (Assignees of Fischer, K.. and Schacht, E.). Oct. 24, 1927, [Convention date]. Printed records, apparatus for giving.-A weighing machine which may, after a simple manual operation, issue a card printed with the weight and in some cases with the monetary value of the goods, and wherein a number of stepped discs or sectors corresponding to the subdivisions of the graduated weight scale, and rotatable in proportion to the movement of the indicating pointer co-operated with feeler rods which may be lowered on to the steps and during their movement actuate corresponding type wheels, is characterized in that the pointer is held in the weight-indicating position by clamping members after which a transmission gearing rotatable separately from the pointer and acting on the stepped discs or segments is moved up to a stop on the pointer and the feeler rods are brought into action. As shown in Fig. 1, by depressing the operating lever 85, the indicating pointer 73 is clamped by means of curved clamping members 76, 77, a loose sector 68 is turned by a spring 97 until arrested by a pin 99 on the pointer thus setting the stepped discs 64, 65, a lever 71 locks the stepped discs, and subsequently, during the return of the hand lever 85, the feeler rods (not shown) are lowered on to the stepped discs by a cam plate 83, lever 82 and draw spring 105, thus setting the type discs by a rack and pinion connection, and the card is subsequently automatically printed, severed from a strip and delivered by suitable mechanism operated by the rotation of the cam plate 83 upon the return of the handle 85. When converting the balance to work between higher limits of weight, a forked lever 107 may be moved so as to place the stepped discs 64, 65 out of operation and slide another pair of stepped discs into operation. To avoid the danger of the feeler rod of the hundreds disc 65 slipping off the edge of one of its steps when the tens disc 64 is in a zero position the hundreds disc is attached to the tens disc by a spring-pressed pin-and-slot connection and the feeler rod of the tens disc carries a detent which shortly before the feeler rod strikes its zero step displaces the hundreds disc slightly so as to bring its receiving step further under its descending feeler rod. If it is desired to print the monetary value of the goods, additional stepped discs or sectors corresponding to various prices per unit-weight are mounted alongside, and rotate with, the weights discs. Feeler rods may be adjusted by hand to positions over the requisite price sectors or discs, or alternatively the sectors may be adjusted, and the monetary value may be printed beside the weight record upon operation of the actuating handle. The Specification as open to inspection under Sect. 91 (3) (a), comprises also a machine, Fig. 1 (Cancelled), wherein the stepped sectors 4, 5 are secured to the fulcrum of the indicating pointer 1. To obtain a printed card, the operator depresses a handle 30 attached to a toothed sector 33 thus causing a cam 47 to swing two levers 20, 21 into locking engagement with a notched sector 28 and with an arc 25 so as to clamp the pointer assembly with its fulcrum knife-edge raised slightly off its bearing 3. During this operation the toothed sector rotates a toothed wheel 37 and ratchet wheel 38 idly beneath a pawl 41 carried by a cam plate 40. The handle 30 is now allowed to return under the action of a spring 31 and the cam plate is rotated, thereby depressing the lever 10 and drawing down the feeler rods 7 on to the steps of the sectors and setting the type wheels 15. A nose piece 42 on the cam engages a lever 43 and with the co-operation of a spring 44 causes the printing hammer 19 to descend upon a paper strip 16 and make a record. The final movement of the cam plate 40 on the toothed sector 33 may be utilized to cut off the card by means of a knife 18 and deliver the card from the machine. This subject-matter does not appear in the Specification as accepted.
