Abstract
162,625. Balthasar, M. A. April 30, 1920, [Convention date]. No Patent granted (Sealing fee not paid). Actions, pneumatic. The diaphragms and valves a, b, and the striking pneumatics c, are each arranged in two tiers, the passages f from the lower valves to the lower pneumatics being arranged downwards and the passages d, d<1>, d<2> from the upper valves to the upper pneumatics being directed in turn upwards, horizontally, and downwards. These passages may be made of large cross-section without interference from the smaller tracker-bar tubes e by making the latter of metal and passing those leading to the upper diaphragms through the portions d in an air-tight manner.
