Abstract: 174,453. Rogers, T. W., (Krupp Akt.-Ges., F.). Oct. 29, 1920. Counters for articles; counters actuated by reciprocating mechanism; associated counters, trip &c.-An arrangement of counting-apparatus, particularly for ascertaining the haulage output of mines, consists of rows of separate counters for each work section of the mine, a totals-counter for each group of sections, and a grand totalscounter for all the groups disposed in a frame A, Fig. 1, at the upper end of the mine shaft. The number of wagon loads from any or all the sections is registered on the corresponding counter by the attendant in charge who depresses the appropriate actuating push-button h<2>. Each separate counter comprises a units and tens numeral wheel B, C loosely mounted on a hollow shaft Q supported in the frame A and rigidly connected to a shaft Q<1> extending outside the frame. To the numeral wheels, on the side facing each other are secured ten-toothed wheels B<1>, C', which are adapted to be engaged by an actuating-pawl J pivoted to plates D loosely mounted on the hollow shaft Q and oscillated by the operation of the corresponding push-button h<2>. The wheels B<1>, C' are so designed that the wheel C<1> and tens wheel C are only advanced by one step after the wheel B' and units wheel B have completed a revolution; the wheel C<1> is of less diameter than the wheel B' and one tooth space of the wheel B' forms a deep notch. The plates D embrace the numeral wheels B, C and are connected by pins d<1> to rods E, to which are connected crank arms F pivoted at a<6> and joined together by bolts f<1> against which bear the short arms G<1> of springs G, the longer arms of which are shaped to engage arcuate recesses in wheels B<2>, C<2> on the numeral wheels. The springs tend to rotate the arm F and plates D in the direction of the arrow X, Fig. 3, thereby causing a projection d<2> on one of the plates to bear against the end h' of the push button h<2>. The rods E are extended at E<3> and bear against crank-arms K<3> on shafts K which also carry cranks k<1> connected in a positive manner to the ends E<1> of the rods E associated with the totals-counters. On the shafts K are also loosely mounted arms N with projections n<1> engaging the cranks k<1> and connected bv a link P to a crank-arm m<2> on a shaft M provided with an arm m<1> positively connected to the grand totals-counter. Each totals-counter has three numeral wheels B. C, R, Fig. 2, and a special pawl J' is provided to effect the transfer from the tens denomination to the hundreds; this pawl is held out of engagement with the tentoothed wheel R<1> associated with the hundreds numeral wheel R by a lateral projection i<2> thereon which engages the pawl J and by means of a single notched disc C<4> secured to the left-hand side of the tens numeral wheel C and the pawl J<1> is operative only when the pawl J engages both wheels B<1>, C<1> and the notch in the disc C<4>. The grand totals-counter is provided with a fourth numeral wheel V which is advanced in a similar manner to the wheel R.
