To all 'whom tmf-ig concern:

Be. it linoivn that l.` Airis n Loomis. a

citizen of the United tilts,l .7. 'resid at Toledo, in the county of Lucas and cat-ate oitY @hic7 have invented new and useful nr prove-ments in (lctave-lilcy Mechanism, ot which the following is a specilication.

rlhe present invention relates to ninsical instruments of the VWood Wind type; and particularly to an octave or register liey mechanism adapted to oboes to enahle the performer to place the notes emitted in either the lower, or the middle or the upper register. ln this particular description of. instrument tvv/o holes additional to the tone ioles and stoppers or covers to control them are provided near vthe month-piece end of the instrument, but. at diilcrent distances from such end, ot which one or the other alone must be opened When certain notes in 'the middle and upper registers., respeo tively, are played, and both et which must be closed when notes are played in the loner register. These holes are otl very small diameter and are liable .to become stopped by accumulation oit vWater and other foreign sulistances. hoe players experience more annoyance tro-in this canse than 'troni any other. To remove such obst the player ordinarily applies his the obstructed hole and sucks or lint betere `he can do so, he. innst remove the hole stopper Atroni the body et the instrnment .enough to leave a olea space around the hole. The rfiechanisnis previously used tor controlling these octave hole `stoppers have had Vtc be disassembled more or less completely in order to permit removal et the stoppers to the necessary distance.

The main obgects oit my invention tivoffold First, to provide means for operating` the octane or register hole .stoppers lmore conveniently to better effect than is possible with the -operating` mechanisms previously used, and second to enable they itoppersy to be easily inovec aside troni the holes Atar enough to permit application of the players lips thereto Without requiring' disinounting5` or disassembling ot the mecha- The first oi" these objects and the essential principles oi the means .which Serial Tio. 590,483.

have devised tor accomplishing it are stated and explained in my Patent No. 1,336,359

dated April (i. 192th and entitled Key mechanism Ytor Wood Wind instrument-s. So tar as that object and result are concerned, the invention herein described and t @ined is substantially identical with the mechanism Jtor the saine purpose disclosed my prior patent.

Vllhe vsecond main `object is accomplished bj: the combination With a inodilied itoiin of the octave key mechanism described in said patent ot a connection between the .ctave hole Stoppers and the means by which such stoppei's are pressed toward the body of the instrument, which is easily disergageable to permit the stoppers to be svnne' bacl entirclv clear ot the holes which they respeeyely cover.

The manner in which these objects are carried into effect and the principles ot the invention for which l seek protection broadly and in detail can be best explained in connection with a description 0l a specific mechanism embodying the invention, and 'tor the purposes ot such description attention is directed to -the drawings annexed to this specification which illustrate the Ylorin of the invention at present preferred by i e.

a. A. register key mechanism 'for woodwind instruments comprising' the combination with the instrument body having octave holes ot two stoppers cooperative with said holes, spring means normally holding both stoppers closed, and two keys coupled with both stoppers so arranged that when one key is pressed upon one of the stoppers only is opened, and when the second key is pressed upon during` maintenance of pressure on the tirst key, the other stopper is opened and the Vfirst opened stopper is closed.

fr register key mechanism for woodwind instruments comprising' the combination with the instrument body having two octave holes, ot Stoppers respectively cooperating with said holes, a floating lever articulated to both Stoppers, a movable ulcrum on which said lever is pivotally supported, a key connected with said 'ulcrum in a manner enabling it to alter the distance of the fulcrum trom the instrument bot y, when pressed upon, a second key connected with one of the stoppers, and spring means arranged to exert 'torce tending to close said stoppe/rs,V

@Tin a wood-wind instrument having tone holes and octave holes, Stoppers for the respective octave holes, a key connected to one of said stoppers and extending into such proximity to one ot the tone holes that it may be pressed upon by the knuckle of a ringer whose tip is placed over said tone hole, a coupling member engaged with both oi' said stoppe-rs, a second key, a spring organised to act on said coupling member, the

key being arranged to raise the coupling member between the stoppers when pressed upon and the spring arranged to exert force toward the instrument on the coupling member at a point between the secon-d stopper and the point at which the action of the second key is transmitted to the coupling member.

7. A key mechanism for wood wind instruments comprising two stoppers, alever extending between said Stoppers and articulated to both, a ulcrum support on which said lever is mounted and being arranged tor swinging movement about the same axis with the stoppers, a spring actuated presser disconnectedly engaged with said lever arranged to apply force thereon toward the instrument body, a key, and a disengageable pressure transmitting member between said key and Jrulcrum support arranged to cause raising of said support when the key is pressed upon.

8. ln a musical instrument the combination with a hole stopper pivotally connected with the body of the instrument, of a presser having a detachable engagement with said stopper, a spring acting on said presser causing it to apply force on the stopper toward said body, a key, and a stopper lifter connected with said key and having engagement with the stopper which engagement is positive only in the direction away from said body, whereby upon disconnection of the presser from the stopper the latter is left free to be swung away from the body.

9. A musical instrument having a lateral hole and a stopper pivotally mounted upon the body of the instrument to close and open said hole, and an operating mechanism for said stopper adapted to be readily disconnected therefrom whereby to permit wide swinging movement of the stopper away from the hole far enough to permit application of the players lips thereto, said mechanism comprising a spring-pressed arm mounted on a ditferent axis from that of the stopper and a key operated arm also on a different axis from that of the stopper, the irst-named arm being arranged to apply force on the stopper toward the body and being laterally shiftable to a position wherein it is unable to apply such force, and the key operated arm being arranged to apply lifting force to the stopper and being otherwise unconnected therewith.

A. musical instrument having a lateral tone hole and a stopper pivoted on the body of the instrument and movable to close and uncover said hole, a presser pivotally connected to said body on a different axis tc that of the stopper and being also displaceable in the direction of said axis, a spring acting on said presser tending to move it toward the body, an abutment associated with the stopper arranged to receive the pressure of said presser when the latter is in one limit of its aXial displacement and to be clear of the presser when the latter is in the opposite limit of such displacement, and a key having means for raising the stopper but being otherwise unconnected therewith.

ll. A key and stopper mechanism for wood wind instruments comprising a plurality of stoppers pivoted on substantially the saine axis to the body of the instrumentl` a lever articulated to both Stoppers, a tulcruin support carrying said lever and pivoted on substantially the same axis as the stoppers, said lever having an interior abutment facing away from the body and an angular channel leading from one edge of the lever to said abutment, a presser arm pivotally mounted on an axis parallel to the previously mentioned axes and also being movable lengthwise of its axis, said presser being adapted to pass through said entra-nce channel by virtue of pivotal and axial movement-s and come to bear on the abutment, a spring arranged to urge said presser toward the body, a key having an engagement with the fulcrum support for raising the latter and being otherwise disconnected from the Stoppers and lever, and a second key rigidly connected with one of the stop pers.
