P
UT a player piano into a modern steam-heated home an
what happens? It gradually dries out; screws beccfm
loosened and losses of air occur; and more and more peda
ing effort is required to keep the bellows full.

In other words, the high vacuum has been lost.
The securing and maintaining of a high vacuum is @n
of the greatest problems in player action building.
We have met 14 different, serious obstacles to the main
taining of a high vacuum, including the drying-out of th
action described above. We have "stayed on the job" wij]
each one of these until we "licked" it.
As a result the Simplex is one of the tightest actions kno^vi
to the trade today.
This loosening of the screws and the consequent weakening
of the vacuum, described above, have been solved in th'
Simplex by a new process of packing our joints. The sav
ing of air by this process makes pedaling at least 100% easie
than it is with actions packed by any other process.

WE TESTED TWO PNEUMATICS SIDE BY SIDI
One was packed by the old-fashioned method, the otbe
by the new Simplex method. Both pneumatics were screwe
into position as tightly as possible. In each, the vacuur,
held up practically an equal length of time.
Then we loosened the screws one turn on both. Pneij
