Jan. 25, 1938. J. SATTLER WIND MUSICAL INSTRUMENT Filed Aug. 15, 1936 ATTORN EYS A ITNESS Patented Jan. 25, 1933 UNITED STATES GFFlCE Application August 15, 1936, Serial No. 96,273 In Czechoslovakia November 1, 1935 1 Claim.

This invention relates to wind musical instru ments and has for the primary object the provi sion of a device of this character which will require on the part of the musician. less efiort to play and has the draws thereof arranged as to materially decrease the accumulation. of saliva therein and to reduce to a minimum the resistance to air passing therethrough and also provides protection to the valves of the instrument.

Another object of this invention is the provi sion of a device of this character having oscillating valves and improved operating means there for so that finger movements will be materially shortened whereby tone variations may be terially improved.

With these and other objects in view, this invention consists in certain novel features of con struction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation illustrating a wind musical instrument constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 3.

Figure 3 is a transverse sectional view taken on the line 3--3 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a fragmentary sectional view showing the arrangement of the valves relative to the draws and the bell and mouth piece tubes of the instrument.

Referring in detail to the drawing, the numeral I indicates a bell of the instrument formed integrally with a bell tube 2 consisting of upper and lower runs 3 and 4 which are joined by a curved portion 5. The runs 3 and 4 and connecting portion 5 form a continuous air passage to the bell l.

The character 6 indicates a mouth piece of a conventional type which is connected to one end of a mouth piece tube 1 paralleling the run 3 of the bell 1. One end of a draw 8 is slidably connected to the mouth piece tube 1 and includes upper and lower runs 9 and 50 connected by a curved portion II. The connecting portion H is slidably connected to the runs 8 and iii and cooperate therewith in forming an air passage leading from the mouth piece 6 by way of the mouth piece tube 1. The connecting portion it has a drain valve 12 so located that any saliva (Cl. S t-390) collecting therein may be readily drained by opcning the valve. The instrument also includes draws l3, M and IS. The draw 8 is of the maximum length, the draw I3 is slightly shorter than the draw 8 and the draw It is slightly shorter than the draw 53, while the draw l5 the shortest of all of the draws. The runs of the draws I3 and M are disposed horizontally while the runs of the draw l5 are disposed vertically. The runs of the draws 13, I4 and I5 are groups between the bell tube 2 and the runs 4 and Tubular valve casings iii. ii and iii are arranged transversely of the draws and each have ports 19, 20, 2! and 22. The run ill of the draw 8 is connected with the port 2i of the valve casing ill. One run of the draw I3 is connected to the port 59 of the valve casing l6 and the other run of the draw I3 is connected to the port 26 of said valve casing iii. A tube 23 connects the port of the valve casing Iii to the port 2! of the valve 1 casing IT. A tube 24 connects the port 22 of the valve casing I! to the port 2| of the valve casing l8. The tubes 23 and 24 are in alignment with the run ill of the draw 8 and with the run 4 of the bell tube 2 and provide between the draw 8 and the bell tube a substantially unobstructed air passage, thereby eliminating to a minimum resistance to the flow of air from the draw 8 to the bell tube 2.

One end of the draw I5 is connected to the port IQ of the valve casing ii and the other end of said draw I5 is connected to the port 23 of the valve casing 11. One end of the draw M is connected to the port 2!) of the valve casing l8 and the other end of the draw I4 is connected to the port 19 of the valve casing l8. The connection between the draws and the valve casings is such as to reduce obstructions to air flowing through the draws and valve casings to a minimum.

Mounted for oscillatory movement in the valve casings l6, ll and i8 are valve elements 25, 26 and 2'5, each having a port 28 therethrough. The interior walls of the valve casings are slightly tapered and the valve elements are correspondingly shaped for the purpose of taking up wear The' lil

guides 32 pass between the bell tube 2 and the mouth piece tube 7. Seats 34 are provided in the guides and engaging said seats are coil springs 35 to also contact the plungers for urging the plungers upwardly and to position the valve elements to close the draws l3, I4 and I5 to the draw 8 and bell tube 2. By referring to Figure 2 it will be seen that the links 30 when the valve elements are in closed position are slightly offset from dead center so that when the finger pieces are depressed the valves move into open position requiring only a very short movement of the plungers. The short movements of the plungers permit quicker opening and closing of the valve elements and consequently permit tone variations to be materially improved.

As shown in Figure 5, the valve element 26 is positioned to permit the flow of air from the draw 8 through the draw [5 to the bell tube, the other valve elements, namely 25 and 21, being in closed position. However, when the finger pieces of the valve elements 25 or 21 are depressed said valve elements 25 and 21 will move into positions similar to that shown relative to the valve element 26.

The valve casings have removable end caps 26' so that the valve elements may be easily removed when detached from the links. Also bearing discs are provided in the valve casings for the valve elements they being indicated by the character 3T.

The positioning of the finger pieces and guides for the plungers as described, permits this instrument to be played by either right or left hand musicians, Also the arrangement of the runs 4 and Ill and 9 and 3 afford a maximum protection to the valves in case the horn is dropped.

Having described the invention, I claim:

A musical instrument comprising a mouth piece, a mouth piece tube connected to the mouth piece, a bell, a bell tube integral with the bell and including upper and lower runs and a curved connecting portion and having the upper run paralleling the mouth piece tube, a draw connected to the mouth piece tube and including upper and lower runs and a connecting portion and having the lower run aligning with the lower run of the bell tube, valve casings and one of said valve casings connected to the lower run of the bell tube and with the valve casing connected to the lower run of the draw, tubes connecting the valve casings and located in a plane with the lower runs of the bell tube and the draw, a series of draws connected to the valve casings and each varying as to length and all shorter than the first-named draw, valve elements having passages mounted in the valve casings for oscillatory movement, vertically arranged plungers operatively connected to the valve elements for oscillating the latter during the reciprocation thereof, vertical guides for supporting said plungers and formed on the valve casings, finger pieces for said plungers and located in a plane slightly above the upper run of the bell tube, springs located in the guides for acting on the plungers for urging the valves into closed position, said valve casings being disposed transversely relative to the draws, bell tube and mouth piece tube and in a plane above the lower runs of the first-named draw and the bell tube.
