THE MUSIC TRADE REVIEW
Every pneumatic re-
quires a iralvc that fits
it specially. Valve space
varies from .160 to .175
of an inch. We permit a
variation of only .002
of an inch in the finished
result. The dial of this
nezv machine at right, in-
vented by Mr. Brown,
shows the exact thick-
ness of the valve in
loooths of an inch.
This Wonderful Machine
Puts Microscopic Exactness into the Simplex Action
I
T is a special measuring device which makes every valve in a Simplex
perfect to the 2-IOOOths of an inch. By doing this it destroys the re-
motest chance of valve disorder. And it puts last-degree certainty
into playing.
The young woman worker measures the valve and the unit pneumatic
under the guiding dial. Infallibly she secures a perfect relation between
valve and pneumatic—a relation which eliminates regulation and adjust-
ment later.
With this safeguard, binding, dislodgment or leaking are practically
impossible in a Simplex Action.
This machine is a master touch in action building. And there are a score of
other remarkable machines, processes and features used exclusively in the Simplex.
The genius back of it—Theodore P. Brown—invented the first interior
player action 20 years ago. He has been constantly contributing new inven-
tions to the player industry ever since. Not only his player parts, but his special
machinery have made the Simplex plant a remarkable model of factory efficiency.
Boiling 19 Parts Down to 4 Also a Simplex Feat
The famous Simplex 4-Piece Valve alone represents a startling advance in
mechanics. Mr. Brown produced it by a slow, infinitely painstaking process of
weeding out. Detail by detail he cut the construction down. This required
years. When from a 19-part valve he had evolved a 7-part one, the result
was hailed as a big event. But to-day the simple, sure efficiency of the 4-part
valve represents one of the biggest steps in player construction of the century.
But that is only a single Simplex detail.
The whole Simplex policy—years ahead of its competitors—is to wipe out
every unnecessary, cumbersome element in a player.
The Simplex Unit Pneumatic, for example, is instantly removable or inter-
changeable by the simple loosening of two easily accessible screws. Which
means no more shelves of pneumatics to unpack and repack.
The Simplex Trapezoid Tracker Bar abolishes tracking trouble at its actual
source. The Simplex Bellows Set gives instant, perfect responsiveness. The
Simplex Control is simple and sensitive to the last degree. And so on through
the list of Simplex features, will you find fundamental differences from other
actions. And here is a final point worthy of note:
Mr. Brown has established in the Simplex plant a Cost System that watches
every tiny detail of production—undoubtedly the most practical system in oper-
ation in any action factory to-day. Through this is made possible the surprisingly
lotv cost of Simplex Action.

To Manufacturers: Ship us one of your
pianos and let us install a Simplex Action
and return it to you. Test it alongside a
piano with any other action made. It will
sell itself without a word from us. A t all
events write us for prices, etc., to-day.
T o Dealers: It will more than pay you
to write us for a list of factories using Sim-
plex Actions. To-day. •
