Application filed July 17,1905. saga No.26 9.9 i7." V I To all whomit may concern: 3 v j I 4 I Be it knownthat I, J oHN W. MACY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Pneumatic-Motor Governors, for all the air enterlng the motor and utilized of which the following is a specification. The object of my invention is to provide a pneumatic-motor governor such as is employed in pneumatic musical instruments for crating the devices, which propel tlt e musics. eet which will insure aneven action of the motor under. the varying conditions of bellows-pressure and, reserve uniformity in time of the music in epen'dent of the variation in vacuum-pressure of the operating neumatic system. i This ob'ect 'I attain as illustrated and described in t e specification and definitely s ecified in the claims.
The drawing illustrates the practical application of my pneumatic-motor governor with an exhaust-bellows, a pneumat1c-motor, and an airway leading from the motor to the bellows, throu h which the air passes from the former to t e latter and in which apartial vacuum is maintained of greater or lesser exhaustpressure, upon which the action of the motor depends.
Referring to the drawing and the numerals of reference, 1 denotes an exhaust-bellows of any suitable form as applied to instruments of this class. 2 isa motor of an approved form, operated by suction or-eXliaust-pressure, having pneumatics 3, which operate arevolving crank-shaft 4. Connected with the motor is an airway 5, leadin to the exhaust-bellows; which conducts the air from the motor to the bellows when the same is in action.
' The bellows 1 may be operated by the pedals '6 or by any other suitable means. At a convenient point in the airway 5 from the motor to the exhaust-bellows I place a regulating cut-ofl valve 7 of any approved type, the action of which regulates the amount of air assing through the valve-passage 8.
11 order to operate the regulating-valve automatically, I employ a overnor 9, consisting of a pneumatic or befiows maintained in a collapsed condition by a spring '10 or other suitable means. The overnor 9 is inclosed in the airway 5, whic is enlarged at thlspoint to form a pneumatic-chamber 11.
It communicates with the outer air by means of the passage L2, leading through the wall of said chamber. v The movable member 'ofsaid governor is connected with the cut-off valve 7 bly the link 13'. 't
is customary in this class of governors for its operation to pass through the 'governor-pneumatic on its way to the exhaust-j. bellows. Iavoid this in my improved conchamber in which] the overnor-pneumatic is placed and maintainer? in a collapsed condition. The pneumaticchamber becomes a reservoir for the air on its way from the mo- .tor and is rendered flexible and'elastic b the action of the governor-pneumatic, whic has free communication with theouter air. The .chamber thus becomes extremely sensitive to, the action of the cut-off valve as controlled by the governor, and a uniform vacuum-pressure is maintained therein. In this instance the air from the motor passes through the air- I way 5, including the pneumatic-chamber 11 and cut-off valve 7, on its way to the exhaustbellows. The governor 9 in the chamber 11 of the airway 5 responds to the variations in vacuumressure, with the result that if the force of t e exhaust-bellows varies the action of the governorneumatic correspondingly varies, and by t e motion of its movable member and connections with the regulating-valve there is a corresponding opening and closing of the same, which regulatesithe degree of suction or vacuum-pressure, and the motor operates with a steady and juniform motion. 7 The spring 10 maintains the governor-pneumatic in a collapsed condition and isv provided with a nut 14 or other means by which the degree of resistance in the pneu-- maticis adjusted. I
I do not confine myself to any particular style of motor or to any individual combination in a pneumatic musical instrument player, as it is apparent that m governor can be employed 1n the manner escribed in an instrument of this class.
