ATTOR Patented Dec. 18, 1934 UNITED STATES WIND MUSICAL INSTRUMENT Louis M. Schaefer, Elkhart, Ind., assignor to C. G. Conn, Ltd., Elkhart, Ind., a corporation of Indiana Application December 16, 1933, Serial No. 702,655
9 Claims.
My invention relates to valved wind musical instruments, and particularly to instruments carrying piston valves.
The piston valves of cornets, and other wind musical instruments which have reciprocating valves, are provided with some suitable means to prevent casual rotation of the valves in order that the proper and necessary registration of the valve ports and passages with the valve casing ports and passages may be effected. Such means to prevent rotation of the instrument valves has taken many forms, all of which are more or less effective, objectionable to some degree, especially because of undue friction and Wear on the various parts, and on account of audible clicking of the parts incorporated therein.
The principal object of my invention is to provide improved and much simplified means for preventing casual rotation of the reciprocatory valves incorporated in comets, and like wind musical instruments.
Another object of the invention is to provide simple and improved means for preventing rotation of the reciprocatory valve in wind musical instruments of the character described, such means comprising a stem fixedly connected with the valve eccentrically of the valve axis andslidably associated with a stem bearing means carried by the valve casing.
A third object of the invention is to provide simple and improved means for preventing rota-- tion of the reciprocatory valve in wind musical instruments of the character described, such means comprising a stem fixedly connected with the valve eccentrically of the valve axis and slidably associated with a valve casing head which is removably mounted in the Valve casing.
Still another object is to provide improved and simplified means for actuating the reciprocatory valve of cornets, or like instruments, said means including means to prevent casual rotation of the valve in the valve casing.
A further object of the invention is to provide a unitary stem for the reciprocatory valve of cornets, and like instruments, which functions both as a valve actuating element and also as means to prevent rotation of the valve in the valve casing.
Other and more specific objects of the invention are mentioned and described herein.
An embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 illustrates a iragmental side view of a wind musical instrument of the comet type in which my invention is incorporated;
tion illustrating the depressed position of the valve;
Figure 5 is a section taken on line 5-5 of Figure 4;
Figure 6 illustrates a side view of the valve casing head; and
Figure '1 is a section taken on line '7--7 of Figure 6.
Similar numerals of reference indicate like parts throughout the several views on the drawing.
Referring now to the details of the drawing the numeral 1 indicates the tubular cornet valve casing of the conventional type and within which the usual reciprocatory cylindrical piston valve 2 is mounted, said valve being normally upwardly urged by a coil spring 3 arranged within said valve casing and seated upon the inner face of the casing bottom cap 4.
The valve 2 may be provided with the usual ports and passages-mot shownwhich are well known in the art, and said valve may be provided also with a top head member 5 which may be fixedly secured therein in any suitable manner. For reciprocally depressing the valve 2 against the spring 3 a stem 6 is provided, and said stem is rigidly fixed in the valve head 5 at 7 and eccentrically in relation to the axis of the valve 2 and the bore of the valve casing 1, said stem extending substantially parallel with the axis of said valve.
The numeral 8 indicates a cylindrical valve casing head removably and non-rotatably mounted in the upper end of the casing 1 and provided with a valve stem bearing bore 9 which bore is formed in said head eccentrically of and parallel 4 with the axis of the valve 2, said head bore being traversed by the stem 6 in which bore the latter is freely reciprocable.
Desirably, the casing head 8 may be provided with an upwardly extending valve stem guide portion 10 in which the upper portion of the bore 9 is formed. The usual finger tip 11 may be mounted upon the upper end of each valve stem 6.
The casing head 8 may be provided with an annular circumferential flange 12 which rests upon the end of the casing 1, said casing head being maintained in juxtaposition within said casing by the annular flange 13 carried by the ring-like casing cap 14, said cap flange overlying and engaging said head flange 12 when the cap 14 is screwed home on the casing end at 15. The casing head 8 may be held against rotation in the casing 1 by a key 16 carried by said head and which projects into a suitable groove formed in the Wall of the valve casing 1 adjacent the upper end thereof. A vent 17 may be formed in the casing head 8, and a non-metallic valve cushion 18 may be carried on the under face of said casing head to cushion the impact of said valve.
From the foregoing it will be evident that the eccentric arrangement of the stem 6 in the easing head bore 9 and its rigid connection with the valve 2 causes said stem to function as a means for valve actuation and also as an element which prevents casual rotation of the valve in the casing. In such manner the ports and passages in both valve 2 and casing 1 are maintained in their proper and necessary relation without the use of any additional means such as keys, stars, and other usual devices.
I claim:
1. In a wind musical instrument of the character described, the combination with a valve casing and a reciprocatory valve therein, of means for reciprocally actuating said valve and maintaining the latter against rotation in said casing, said means comprising a stem fixedly connected with said valve eccentrically of the axis thereof and slidably mounted in said casing in eccentric relation to said valve axis.
