Oct. 7, 1952 F. N. MEYERS VALVE FOR WIND INSTRUMENTS Filed June 9, 1948 E D m v w.

INVENTOR. F350 N. MEYEIRS Patented Oct. 7, 195 2 VALVE FOR WIND INSTRUMENTS Fred N. Meyers, Andover, Ohio, assignor to The H. N. White Company, ClcvelanrLOhio, a corporation of Ohio Application June 9, 1948, Serial no. 31,989 12 Claims. (o1. s s-392) This invention relates, as indicated, to wind instruments, but has reference more particularly to the piston or valve structure of wind instruments of the trumpet or cornet type.

A primary object of the invention is to provide an improved construction of piston assembly for instruments of the aforesaid type.

Another object of the invention is to provide a novel one-piece piston guide having springretaining and other functions.

A further object of the invention is to provide an instrument of the aforesaid type which is remark-ably free from noises in the operation of the piston.

A still further object of the invention isto provide an instrument of the aforesaid character which is characterizedby precision machining, enabling perfect functioning thereof.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a longitudinal cross-sectional viewof a piston assembly embodying the novel features of the invention, with the piston stem elevating sprin somewhat compressed, in order to more clearly show certain elements of the construction; Q

Fig. 3 is a plan view of one face of the novel piston guide of the invention;

Fig. 4. is a view, partly in elevation, and partly in section, taken on the line 4-4 of Fig. 3;

Fig. 5 is a plan view'of the other face of the piston guide, and

Fig. 6 is a fragmentary elevational view, showing the keyway for the piston guide in the valve case body. Y v

Referring inore'particularlyto the drawings, i designates a portion of the valve case assembly of a musical instrument of the trumpet type,

such valve case comprising a cylindrical body 2 having various holes or openings in the walls thereof for passage of air therethrough, and having an extension 3, of reduced external diameter, provided at one point in the wall thereof with a lzeyway 3. A ballaster 5 is secured to the extension 3, and has secured to one end thereof athreaded ring 6. V

Slidably mounted within the valve casebody 2, for reciprocal movement therein, is a piston 7 having various air passageways extending therethrough adapted to be aligned with the openings in the walls of the valve case body 2. Secured within one end of the piston l is a piston bottoms, and secured within'the other end of the'piston is a piston head 9. The head 9 is provided with an annular flange it which abuts the end of the piston. A portion of the flange it is removed to provide an annular seat H, which serves a purpose to be presently described.

' Rigidly secured to the head 9 is a spring barrel l2, in the form of a cylindrical member, which is internally threaded, as at l3, and is provided withfan elongated opening It in the wall thereof, said opening being defined by side edges iii and it, which are parallel with the axis of the barrel, and end edges I1 and 18 which are perpendlcular to the side edges.

Secured to the threads l3 of the barrel i2 is a stem l9 provided with an annular flange '2!) which abuts the end of the barrel and has a portion thereof cut away, as at 2| to provide an annular seat for a compression coil spring Zla.

The piston assembly further includes a cork washer 2 2,a felt washer 23, a top cap 2%, and a finger button assembly comprising a finger button 25, the button 25 being threadedly secured to thestem l9.

' The present invention is concerned principally with the provision of a novel piston guide which will now-be described.

The piston guide comprises an annular member having a short cylindrical portion 23, which normally rests on the annularseat I I of the head 9; The inner diameter of the cylindrical portion 28 of the piston guide is approximately the same as the diameter of the portion of the head 9 which is surrounded by said cylindrical portion of the guide, so that the guide, when in said normal position, is restrained against lateral displacement from said head. The outer diameter of the portion 28 of the piston guide is slightly smaller than the external diameter of the piston I.

Portions of the cylindrical portion 28 of the piston guide are removed to form circumferentially-spaced rectangular openings 20 and 30, the

metal of the portion 28 between these openings bein displaced in a radially-outward direction to a distance of approximately the thickness of the portion 28 to provide a tongue or key 3|, which is'adapted for entry into the keyway l of the valve case body 2.

The piston guide is also provided with a short cylindrical portion 32, the outer diameter of The guide also includes a tongue 34 which projects radially inwardly from the flange 33 and is coplanar with such flange. This tongue extends into the opening H in the barrel l2, and

has parallel sides 35 and 36 which slide along the edges l and I6 respectively of the opening [4, thereby constraining the guide against rotation relatively to the barrel.

The outer diameter of the portion 32 of the guide functions to centralize the guide in the valve case, while the tongue 34 functions to maintain the guide in alignment with'the spring barrel and prevents the guide from rotating.

The tongue or key 3! is adapted to enter the keyway 4, thereby accurately locating the piston circumferentially with respect to the valve case body, and insuring that'the openings in the piston will be accurately aligned or registered with the openings in the valve case body. The key '3! also facilitates assembly of the piston assembly with the valve case.

The provision of the openings 29 and 33in the guide enable the guide to be rapidly assembled with the spring barrel,.these "openings forming clearance areas enabling the guide to be 'canted relatively to the barrel during assembly, so as to permit entry of the tongue 34.1nto the -slot 14.

Through the use of a pistonguide of the aforesaid character, in combination with other associated elements of the piston assembly, a number of distinct advantages are obtained, among which are the following:

(a) The piston is extremely'quiet in operation, performing more quietlythan in'instruments embodying conventional construction "in the piston assembly and guides.

(b) The one-piece construction of the piston guide provides a multifunction member in the form of a single element, which .can be easily manufactured and is well-adapted'to serve all of its functions. In conventional instruments, two or three separate parts are required to serve all of these functions.

(c) The instrument as a whole, is characterized by extremely easy actionof the piston'assembly, and is remarkably free from clicking and scratching noises. A

(d) Conventional forms of guides havea .two or three point bearing on thespring barrel. so that tilting of the guide is possible and frequently occurs during the action of the piston, whereas the present guide is guided along one side only, so that it cannot tilt accidently, once it.is inserted in the barrel in the required manner.

(e) The design of the guide and ,piston assembly is characterized by precision machining, enabling perfect functioning thereof.

Although the guide and pistonassembly'have been described with reference to a trumpet, it will be readily understood that the'invention is also adapted for use in wind instruments generally, such as cornets, altoes, baritones, sousaphones, etc.

It is to be understood that theiform of my inthereof, a stem secured to said barrel, said stem having an annular flange formed integrally therewith, a piston guide embracing said barrel. said guide comprising an annular member having a tongue formed integrally therewith and extending radially-inwardly into said opening, and a compression coil spring interposed between said flange and said guide, said tongue terminating at a point slightly radially inwardly of said opening.
