Specification of Letters Patent.
Patented Apr. 4, 1916.
Application filed September 16, 1911. Serial No. 649,692.
To all whom it may concern Be it known that I, GEORGE B. MAGKEY a citizen of the United States, residing at Anniston, county of Calhoun, State of Alabama, have invented certain new and useful Improvements in Comets, of which the following is a specification, reference being had drawing.
This invention relates to certain new and useful improvements in wind instruments and more particularly to cornets and the like, the object being to provide an instrument which is so constructed that the valve tone has the same free air passage as the open tone, the column of air passing through a passage devoid of obstructions with the least possible resistance.
Another object of the invention is to provide an instrument in which the inlet and outlet openings of the valve casings are connected by compound bent pipes in order toallow the air to pass into and out of the valve casings in a passage devoid of angles or obstructions of any kind. v
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claim.
11 the drawings-Figure 1 is a side elevation of my improved cornet showing the valves in open tone position; Fig. 2 is a section taken on line 22 of Fig. 1; Fig. 3 is an elevation of one of the valves removed; Fig. 4 is a side elevation showing the valves depressed in valve tone position; and Fig. 5 is a section taken on line 5-5 of Fig. 4.
Like numerals of reference refer to like parts in the several figures of the drawings.
In the drawing, 1 indicates the first valve casing, 2 the second valve casing, and 3 the third valve casing of a wind instrument constructed in accordance with my invention. Each of the first and second valve casings is provided with upper and lower inlets and outlets preferably at right angles to each other and in the same horizontal planes, respectively.
The valve casings are arranged as clearly shown in the drawing when the instrument is in position for playing, with the first valve casing closest to the mouth piece, the second valve casing next and the third valve casing the farthest away.
Connected to the inlet of the upper inlet of the third valve casing, is a mouth tube 4 which is connected to the mouth pipe 6 by a tuning slide 5 as clearly shown. Connected to the outlet of the first valve casing 1, is an outlet pipe 7 terminating in a bell 8. Mounted within each of the valve casings 1, 2 and 3 is a cylindrical valve 9 which is held in position by the usual spring, not shown; said valve being provided with curved passages communicating with the inlets and outlets of the valve casings.
The upper outlet of the third valve casing is connected to the inlet thereof by a vertically arranged compound bent pipe 10 and the lower outlet thereof is connected to the lower inlet of the second valve casing by a horizontally arranged pipe 11 and the lower outlet of the second valve casing is connected to the upper inlet thereof, by a vertically arranged compound bent pipe 12. The upper outlet of this casing is connected to the upper inlet of the first valve casing by a horizontally arranged pipe 13. The upper outlet of the first valve casing is connected to the lower inlet thereof by a vertically arranged compound bent pipe 14.
The valves 9 mounted within said casings are provided with curved passages constructed as shown, in order to bring into communication the inlets and outlets of the valve caslngs in such a manner as to allow the air to pass through the valves and tubes when in open-tone position, as shown in Figs. 1 and 2, in a direction as clearly illustrated by the arrows in such a manner that the passages formed thereby, are devoid of obstructions of any kind, whereby the air will pass through these passages, valves and casings with the least possible resistance. As shown, the air enters the mouth pipe 6, passes through the tuning slide 5, extension 4 into and through the inlets and outlets of the third valve casing; through the compound bent pipe 10 into and through the connecting pipe 11 and into the lower inlet of the second valve casing, from which point it passes through the valve, out the outlet through the compound bent pipe, back into the casing, out the pipe 13 into the casing of the first valve, out the outlet, into the compound bent pipe 14, back into the easing; the air following the passage thus formed which is upon curved lines in order to reduce the resistance.
In Figs. 4 and 5, I show the valves in valve tone position and the first valve casing is provided with ports to which the first crook 15 is connected, the second valve casing with similar ports to which a second crook 16 is connected and the third valve with ports to which a third crook 17 is connected, said ports and crooks being so arranged in respect to the inlets and outlets of the valve casings that when the valves 9 are depressed in order to produce valve tone, the passages thereof will bring into communication the inlets and outlets and ports. This will allow the air to pass through the mouth pipe into the third valve casing, through the passage of the valve therein and port into the third crook, through said valve casing again into the second valve, through the lower outlet and inlet, through the second; crook into and through the second valve casing again and into the first valve casing from which it passes into the first crook; the air passes through said crook into and through the first valve casing, into the bell pipe and out through the bell and it will be seen that the air, in passing through the valve casings, when the valves are in this position, follows a passage devoid of angles formed by the respective passages in order to allow the air to have the same free air passage when the valves are in valve tone position as they have when in open tone position. It will also be noticed that the air from the mouth pipe in open tone or valve tone position passes into and through the third valve from which it isdischarged into and through the second and first valves in a passage devoid of obstruction, thereby decreasing the relet at right angles to each other in a lower horizontal plane, vertically arranged cornpound bent pipes connecting one of. the lower inlets and one of the upper outlets of each of said valve casings, horizontal pipes connecting the other inlets and outlets of the first and third valve casings to these'cond valve casing, a mouth pipe tube connected to one of the upper inlets of the third valve casing, said first, second and third valve casings being provided with ports in a horizontal plane with the upper inlets to which crooks of different lengths are connected, and a bell pipe connected to the lower outlet of the first valve casing.
In testimony whereof I afiix my signature in presence of two witnesses.
