MOUTHPIECE FOR WIND INSTRUMENTS Filed July 8, 1930 I I i Patented Feb. 9, 1932 PATENT OFFICE LOGAN RIVES, OF LOS ANGELES, CALIFORNIA MOUTHPIECE FOR WIND INSTRUMENTS Application filed July 8, 1930.

' forth in my Patent No. 1,750,051, filed August 17, 1927, Serial No. 213,541, allowed July 19, 1929,'issued March 11, 1930. I

In a musical instrument of the type set forth in my patent above mentioned it has been sometimes found that the pitch is not always true when various keys are operated,

i and this seems to be due to the fact that the vibrating re'ed is not sufficiently close to what may be termed a divid ng lme connecting the two air columns and causing these to v1- brate as a single column.

An object, therefore, of my invention is the construction of the mouthpiece and attachment of such mouthpiece to a multiple tube musical instrument whereby the ports leading to such instrument are close and substantially the same distance from the vibrating reed. By this construction there is substantially no vibrating air column distinct and separate from that confined in the tubes ofthe musical instrument.

The mouthpiece may be constructed in a number of different manners for attachment to different types and shapes of multiple tubes in which the multiple air columns have a single and similar Vibration. The mouthpiece may be arranged in alignment with one of the tubes and have a port for the other tube substantially adjacent the reed, or the mouthpiece may be positioned so that the reed is substantially midway between two tubes, 01 1f the tubes connect to the mouthpiece at an angle the reed is substantially at the junction line of the various tubes.

My invention is illustrated in connection with the accompanying drawings in which Fig. 1 is a plan of one form of my inven tion taken in the direction of the arrow 1 of Fig. 2.

Fig. 2 is a side elevation taken in the direction of the arrow 2 of Fig. 1.

Fig. 3 is a longitudinal, horizontal section Serial No. 466,451.

taken on the line 33 of Fig. 2 is the direction of the arrows.

Fig. 4 is a plan of modification with the reed substantially midway between the pair of tubes.

Fig. 5 is a plan of another modification in which the tubes are connected to the mouthpiece at right angles.

Fig. 6 is a plan of a further modified form in which the mouthpiece connects to the device at an acute angle.

Fig. 7 is a plan of construction having multiple tubes with the reed in alignment with one of the tubes and meeting the other tubes at an angle.

Fig. 8 is a plan of a further modification of my invention with a mouthpiece suitable for a horn or the like.

Referring first to the construction of Figs. 1, 2, and 3. The mouthpiece is designated generally by the numeral 11. This has on the top a lay 12 for the reed. The opening in the mouthpiece is indicated by the numeral 13 and the reed indicated at 1 1 secured in place by the usual clamping ring 15. In this construction there is a port 16 to which is connected one of the instrument tubes 17, and a second port 18 to which is connected the other instrument tube 19.

It will be seen that the port 16 and the tube 17 are substantially in alignment with the reed and that the mouthpiece has a lateral offset to the port 18 so that this port and the tube 19 are offset from the axis of the reed. However, the distance between the ports 16 and 18 and the reed are substantially equal, and as the tubes 17 and 19 connect directly to the mouthpiece, which is of comparatively short length, there is no section of the tube which may influence the vibration of the air column in the air of tubes, but these are influenced only by the vibration excited by the reed of the mouthpiece.

In the construction of Fig. 4 the mouthpiece 21 has the lay for the reed 22 centrally positioned with the opening 23 through the lay. In this case there are two lateral ports 24- and 25 with the instrument tubes 26 and 27 connected therein. In this case the reed is centrally positioned between the two tubes .has the usual 26 and 27, which are parallel, and the distance from the reed to the ports 24 and 25 is substantially equal.

In the construction of Fig. 5 the mouthpiece 28 has a lay 29 for the reed and this 1s in alignment with the port 30. At right angles to the axis of the reed there is a second port 31. In these ports there are fitted the instrument tubes 32 and 33 which are thus at right angles one to the other. In this construction, however, the distancebetween th ports and 31 and the vibrating reed is substantially equal. i

In the construction of Fig. 6 the mouthpiece 34 has a lay 35 for the reed. This-lay angle with the reed secured in the lay. In this case there is a port 36 having an instrument tube 37 in alignment with the axis of the reed and a second port 38 having the tube 39 which extends from the mouthpiece and from the line of the axis of the reed at an acute angle.

In the construction of Fig. 7 the mouthpiece 40 has a lay 41 forthe reed with the usual opening. .The mouthpiece has a transverse, tubular member 42 which is illustrated as being tapered and has a port 43 on the tapered end connected to a tapered tube 44. On the opposite side there is aport 45, this being on the large end of the element 42, and to this there is connected .a tapered tube 46. In this case it will be seen that the reed and ohe reed opening have a direct action .on the aircolumn in the tubes 44 and 46. Thus, the air in these tubes will respond to the vibration excited by the reedto give the true pitch for the different notes sounded by the instrument.

Itwill be noted that the construction of Figs. 1 thrQugh 4, in which the 'mout-hpiece forms a reverse connection for the tubes, is,

in effect, equivalent to havingthe tubes themselves bent into reverse bend as shown in my patent above mentioned. Therefore, it may be considered thatwith this mouthpiece connection I have a single tube with a reverse connection, the tube being of two parts, and

the mouthpiece exciter causing the air col- ,umn in the two tubes to vibrate as a single column.

The connection ofjFigs. 1, 2, and 3, in which the mouthpiece is in alignment with one of the tubes, maybe likened to the connection of Figs. 4 and 5 of my patent; whereas, the connection of Fig. 4 may be likened to the connection of Figs. 1 and 3 of my patent.

In the-construction of'Fig. 8 the mouthpiece 47 the tubes 48 and 49 connected thereto and has a horn type or" vibrating excite-r 50.

the connector, such as the mouthpiece, form or enclose a single air column 5 that is: a sinof the air column.

\Vhile it will be apparent that the mouthpiece may be elongated so that the actual ends of the tubes may be at varying distances from the exciter, nevertheless, in such case, the

mouthpiece may be considered as forming part of the tubes so that the air vibration from the exciter is communicating directly to the single air column.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
