SPEED REGULATING MECHANISM
THE SUCCESS OF THE LAUTER VALVE
Details of Patent Just Granted to Oscar Nelson
and Peter Wiggen, of Chicago, Whereby
Means for Regulating the Speed Mechanism
for Player-Pianos Are Set Forth
As is generally recognized the valve in a
player action is one of the factors of most im-
portance, for if the valve do not seat properly
or is not air tight, if the bleed, valve stem,
valve guide, etc., are not of scientific relative
proportions, the player will not be sensitive to
the demands of the player pianist, and will not
respond. In other words, the valve must be
simple and trouble proof.
The dominating feature of the new Lauter
player action, manufactured in its entirety by
the Lauter Co., Newark, N. J., is the detachable,
interchangeable valve. Any valve may be re-
moved by simply taking out two screws and
may be readily replaced by another. All the.
tools necessary being a screw driver.
There is illustrated herewith the Lauter de-
tachable and interchangeable valve itself, and
the reference character shown on the cut are
as follows: No. 1, valve board containing air
channels and pneumatics; No. 1-A, air passage-
ways to pneumatics; No. 1-B, vacuum port
WASHINGTON, D. C, October 23.—Patent No.
1,201,609 was last week granted to Oscar Nelson
and Peter Wiggen, Chicago, 111., for a speed-
regulating mechanism for pianos, the aim be-
ing to regulate the speed of the winding and re-
winding reels or spools which carry the per-
forated music sheet over the tracker-bar, and
it consists in certain peculiarities of the con-
struction, novel arrangement and operation of
the various parts thereof.
The principal object of the invention is to
provide a variable speed mechanism of the
above named general character which shall be
of such construction and have such combina-
tion and arrangement of its parts, that the
movement of the perforated music sheet over
the tracker-bar can be readily increased or di-
minished while being wound on the "take-up"
spool, or quickly rewound therefrom on the
supply or rewinding spool, without necessitating
any change in the speed or direction of rota-
tion of the power or motor-driven shaft, there-
by affording means for the quick repetition of a
certain piece of music or tune, or if desired,
for quickly placing a certain selection or part
of the sheet, in position to be played, whether
said selection is wound on the supply spool or
shall have been wound on the "take-up" spool.
MUSIC TRACKING DEVICE
WASHINGTON, D. C, October 23.—A music
tracking device for pneumatic pianos (Patent
No. 1,201,925) has been invented by Wm. G.
Betz, Chicago Heights, 111., and one-third of
which has been assigned to Virgil H. Lock-
wood, Indianapolis, Ind.
The object of this invention is to provide an
improved means for automatically maintaining
the music sheet in pneumatic pianos in proper
alinement with reference to the air ports in
the tracker-bar.
Such alinement has hereto-
fore been maintained by means controlled by
the edges of the sheet of music, but since the
edges become worn from handling, such track-
ing means soon becomes inaccurate.
MAKE DISPLAY AT DALLAS FAIR
The J. E. Rogers Piano Co., of Dallas, Tex.,
had a very attractive display of Bush & Lane,
Farrand and Victor pianos at the State Fair at
Dallas, Tex. In this connection the advertise-
ments in the local papers were used to very
good purpose, in which the popularity of the
Bush & Lane players in Texas was pointed out.
Emphasis was placed on the fact that the Bush
& Lane instruments are used in the Kidd-Key
College, at Sherman, Tex.

produce on any player-piano that has made
them such general favorites with owners of
these instruments.
The best artists play them.

CHASE=HACKLEYJPLAYERS IN DEMAND
CHICAGO, I I I . , October 23.—The Chase-Hackley
Piano Co. reports an exceptional demand for its
line of player-pianos. Braton S. Chase, vice-
president and manager of the company, is the
authority for the statement that the demand
for players is fast exceeding anything ever be-
fore experienced in the history of the concern.
Trade conditions are excellent at the present
time, and indications point to a most success-
ful fall and winter demand for the Chase-
Hackley players.
PATENTS NEWflANO PLAYER
WASHINGTON, D. C, October 23.—Patent No.
1,200,209 was last week granted to John Max-
field, London, Eng., for a piano-player, the main
purpose being to provide a construction of
striking pneumatic with primary and second-
ary valves which shall be compact, light and not
liable to deterioration in varying climatic con-
ditions, and which shall obviate the need for
a multiplicity of connecting tubes.
