REVIEW
KRANICH & BACH
PLAYER ACTIONS
with the
Single System of Perforated
Valves are very
different
from the usual Single Valve
Actions.
Illustrating the
FAMOUS PERFORATED VALVE
Pat. May 16, 1911.
Used Exclusively in Kranich & Bach
Player-Pianos.
Illustrating the Perforated Valve in Relation to the Pneumatic.
NOTE THESE ADVANTAGES
1.—The Primary Chest and 88 Primary Valves are entirely eliminated.
2.—Elimination of Primary Valves conduces enormously to non-leakage, maximum air-
tightness-
and slowness of "pumping'
3.—When the Valve Seat is in contact with the individual pneumatic, the air exhausts
from the pneumatic directly through the valve perforation and not in an indirect
manner around angles and corners, as in every other player action. This is the
great feature which differentiates the Kranich & Bach Single Valve System from
all others.
4.—In direct contradiction to criticisms by advocates of the Double Valve Systems,
the notes in a K. & B. Player-Piano will positively speak under either heavy or
light tension if only one-half of each tracker hole is uncovered.
5.—In addition to its simplicity of construction, of maintenance and repair, the very least
we claim for the Kranich & Bach Player-Piano—and which we can demonstrate
beyond any question of doubt—is Artistic Playing Efficiency equal to that of any
other Player-Piano in existence, not excepting any.
An adequate line of finely illustrated Cata-
logues and Player literature on request.
