Abstract: 583,233. Registering - apparatus. COMPANIA PARA LA FABRICACION DE CONTADORES Y MATERIAL INDUSTRIAL SOC. ANON., and VITEAU, P. April 5, 1944, No. 6353. [Classes 106 (i) and 106 (iv)] Registering-apparatus in which means are provided for producing a numerical record of the quantity being measured as well as a graph record on a record strip at-definite time intervals and in which the recording means are not at the end of each time interval returned to zero but move backwardly in order to move forwardly again after they have attained the value of the quantity received during the actual recording and during the backward movement. The operation of the registering-apparatus, Fig. 1, is as follows. The quantity to be measured is applied to shaft 1 which through gearing turns the shaft 14a in the direction of the arrow f. This drive is transferred to the sun wheel 41 which turns the satellite 19 and 20, the shaft 18 thus operating the indicator 33 and the two recording means which comprise four numeral wheels and a recording element 32 which is fixed to a nut 32a which rotates on the screwed end 30 of the shaft 18, the distance of the recording element 32 from a fixed ordinate is a measure of the value received during the time interval, this value also being shown by the numeral wheels. Recording now takes place'as will be described later. The axles 36 and 36a now turn through half a revolution and one revolution respectively, the cams 9, 12 turn, the spring-pressed lever 5 drops and the wheel 6 is instantly engaged with the wheel 15 on which the quantity to be measured now acts. The shaft 20 now free from the lever 38 and urged by spring 28 turns rearwardly driving, through gearing, the cam 17a and the two recording means in a backward direction. During this backward movement the quantity to be measured is received by axle 14 (i.e. wheel 15), the cam 17 moves away from its stopping position and the planet-wheel 42 turns, driving, through gearing, the cam 17a also in a backward direction until it has been arrested by the lever 35a, whereupon the satellite 19 and the recording elements again move forwardly until the end of the time interval when the drive is taken by shaft 1 again. The recording means, Fig. 7, comprises a table 61 carrying at its upper part two wheels 62 over which the paper strip 63 passes. When at the end of the time interval the shaft 36a makes a complete revolution, the four spring- pressed levers 72 are rocked by means of cams 76 so that the hammers 74 strike the ends of the four rods 69 which slide upwardly so causing the numerals to be printed on the paper 63. The inking ribbon which is between the paper strip 63 and the printing wheels is moved automatically. At the same time as the lever 72 is rocked, the spring-pressed lever 77 is moved to strike the flexible blade 81, thus pressing the recording element 32 and the inking ribbon on to the paper strip 63. During this printing operation the numeral wheels which have been aligned by a lever-finger arrangement, Fig. 3 (not shown), are held steady by lever 38 engaging wheel 37, Fig. 1. As soon as the printing is finished, the paper strip 63 is advanced by means of the wheel 64, ratchet-wheel 88, pawl 86, spring-pressed lever 83, cam 82 arrangement.
