Patented Dec. 29, 1925a BUREO E. COBB, OI LGNGYQOD, FLORDA.
Application led May 22, 1324. Serial No. 715,206.
Y all whom. t mary concern.'
Be it known that I, RUnro E. COBB, a citiren o" the United States, residing` at Long'- wood, in the county of Seminole and State et Florida, have invented certain new and usetul Improvements in Mouthpieces, ot' which the following;- is a speciication. y
This invention 'relates to mouth pieces aiflapted to be used upon brass wind instruments and it consists in the novel features hereinafter described and claimed.
in object ot' the invention is to provide a mouth piece which makes it possible for the performer upon a wind instrument, to play the notes in the upper register easily, with- .out the usual amount of muscular effort and 'excessive pressure upon the lips.
lThis result is obtained in general by proridingl` means for shallowing the air chamber or cup or the mouth piece to produce the higher note and thereby shortening` the vi- I n'ations ot the column of air, and at the same time adjusting the tube length and preventing the tones or notes from beingv sharpened or raised in pitch.
frith the above objects in view, the structure includes a base collar, which is slidably 'mounted upon a shank inserted in the tube ol the instrument, and which carries a shell inwinna rim member inserted in the outer end thereof. A cup is slidably mounted in ihe rim member and is provided with a sleeve which enters the shank, means beingl provided 'for simultaneously moving the cup rnd the base collar longitudinally of the elf, and in the opposite directions. A r is interposed between the shank and rim member, and serves to hold the rim ie Lember spaced from the end oi"- the shank.
ln the aecoli1pan vin,'f l drawing:
Figure lA is an end view of the mouth is a side elevation ol the same, ction, and cut on the line Q-2 of lll Figure 3 is a fragmentary vertical sectional. iew ot the mouth piece, out on the line 3--3 olf Figure 2.
fis shown in the accompanying drawino, the mouth piece tube oit the wind instrument indicated at "l, and the said mouth piece tube is provided at its end with a Vflange 2. A. base collar 3 is slidably mounted upon the mouth piece tube l, and carries a cylindrical shell et. A rim member 5 is attached to the end of the shell 4, and is inserted in the said shell. A spring 6 is interposed between the flange 2 and rim member 5 and is coiled around the inner portion oil the rim member. cup member 7 is slidably mounted in the rim member 5, and is provided vwith a tube tl, which is slidably received in the mouth piece tube 'l ot the instrument. Gear wheels :'J are journaled in the flange 2 and ra k arms l() are Carried by the cup 7 and mesh with the teeth of the gear wheels 9 at one side thereof. Rack arms 1l are carried by the lese collar 3, and mesh with the teeth of the gear wheels 9 at the opposite sides thereof, ifi-om the points at which the rack arms l0 engage the said wheels 9.
Jhen using the mouth piece, the perlev ner produces the lower tones in the usual way, and as he ascends the scale pressure is exerted by the hand holding the instrument, thus pressing the rim againstthe lip. The pressure thus exerted on the rim acts to turn through the shell and base, the 'ear wheels which are journalled in the Vange of the shank and the rack arms 10 and i are moved simultaneously in opposite directions, and thus the cup is moved with relation to the rim member and the mouth piece tube and the rim member is moved with relation to the cup and tube l. Then pressure is removed, the spring 6 returns the rim member and the cup to their normal positions. It thus will be seen that any' movement of the rim member in one direction acluates or moves the cup in an opposite direction, and pressure exerted to produce high tones in the instrument causes the cup to move, thus providing a more shallow air chamber between the lips of the performer and the bottom of the cup. rlhis shortens the column oit vibrating air and produces a higher tone with ease, and without the exercise ot excessive pressure. At the same time the length or' the tube of the instrument is varied, and this prevents the tone from beine' raised or made sharp, as would be the case if the air chamber only was shallowed.
Having described the invention, what is claimed is:
l. In a mouth piece, a tubular member, gear wheels journaled on the tubular meml'zer, a base collar slidably mounted upon the tidiular member, a shell carried by the base collar, a rim member inserted in the shell, a spring, interposed between the tubular mem*- ber.y and the rim member, a cup slidably mounted in, the rim member and the tubular1 member, and ruck arms Carried by the cup and the buse` collar and engaging the gear wheels et opposite sides thereof.
2. In combination With a tube musical instruinent, a mouth piece including` a rim member slidably mounted upon the tube, a compression spring holding the rim member in a predetermined position in relation tov lhe tube, a eup slidably mounted in the rim member and the tube, and means operatively connecting the rim member with the cup to cause the rim member and the cup to move simultaneously in opposite directions When the rim member is moved with relation to the tube.
In testimony whereof I eflix my signature.
RUBIO E. COBB.
