UNITED STATES PATENT OFFICE.

JOHN HEALD, OF SPRINGFIELD, MASSACHUSETTS.

CORNET.

SPECIFICATION forming part of Letters Patent No. 408,972, dated August 13, 1889.

Application filed March 20, 1889. Serial No. 303,997.

To aZZ whom it may concern.-

Be it known that 1, JOHN HEALD, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Cornets, of which the following is a specification.

This invention relates to improvements in cornets, the object thereof being to provide an instrument in which the wind-passages through the pipes and the valves thereof, in whichever positions the valves are placed, will be free and continuous and devoid of sharp angular changes in direction, whereby in the employment of the instrument embodying said form of wind-passages therethrough a scale of the greatest uniformity may be produced and the tones thereof may be most easily blown; and the invention consists in the coilstruction and combination of the various parts of the instrument, all substantially as will hereinafter more fully appear, and be set forth in the claim.

In the drawings the present invention in cornets is illustrated, and Figure 1 is a side view of a cornet constructed in accordance with this invention. Fig. 2 is a view, 011 an enlarged scale, of portions of the piston tubes or cases of the eornet, showing the middle short bowed valve-tube and the terminal portions of the longitudinally-extended valvetubes, (the first and the third,) also the portions of the outer valve-tubes proper joining said first and third pistoncases, and indicating by dotted lines the normal positions in.

their cases of the pistons and the valve passages therethrough. Fig. 3 is a view of the piston-valve for the third piston-case. Fig. 4- is a horizontal sectional view of a part of the instrument on the line 44, Fig. 2. Figs. 5 and 6 are diagrams of parts of cornet piston-cases similar to those shown in Fig. 2, but with the pistons indicated as moved to secure an opening from one section of the main-line pipe to the other, through the circuitous bowed outer valve-tubes, Fig. 5 showing, without exaggeration, the course of such passage under the construction of cornets as heretofore,-

while Fig. 6 shows the course of such passage under the improved construction.

As usual in cornets, A represents the one end portion of the main-dine pipe or passage (N0 model.)

to which the mouth-piece Z) is affixed, said pipe being connected to and entered at the lower portion of the piston-case 3.

A represents the other end portion of the main-line pipe, having its outer end of the usual bell or flaring form, and said pipe is connected at the lower portion of the pistoncase 1, and when the piston-valves 10,20, and 30 for the piston-cases 1, 2, and 3 are in their normal or uppermost positions a free and open tone-passage from the portion A through the piston-passages 11, 21, and 31 and short tubular sections 45 and 46, intermediate of and connecting the piston-cases, is established to the end portion A of the main-line pipe.

12, 22, and 32 represent the bowed valvetubes for, and connected by their ends at different heights upon, and respectively to, the

piston cases 1, 2, and 3, and by depressing any of the valve-pistons the wind, instead of passing directly across and through the lower transverse passage 11, 21, or 31 of one of the valvepistons by another passage f thereof, then in proper position, is directed into one end of the respectively adjacent bowed valvetube, and, passing through same, is thence conducted out from its other end by the last or return valve-passage g to the adjacent portion of the mainline passage.

Heretofore in this class of instruments the portions of the outermost longitudinally-extended bowed valve-tubes 12 and 32, joining with the valve-cases 1 and 3, have by their joining portions been extended to their connections with the said valve-cases at right angles to the axes thereof, and the continuations of the passages thereof through the valve-pistons have been necessarily quite angular, as will be noticed on reference to Fig. 5 of the drawings, which is a diagram illustrative of the old method of forming the tubes and passages; but, as seen in the drawings, Figs. 1, 2, and 6, the longitudii'ially-extended valve-tubes 12 and 32 (the first and the third) are constructed with their end por tions 120 and 320, at and about their junction with the outer valve or piston cases proper, inclined in more or less the same direction as the said angular air-passages through the valves, through which valve-passages said valve-tubes 12 and 32 communicate with the open tone or inain line passage. By this about its junction with its respective ease, inclined in about the same angular direction with relation to the axis of said case as s the respective passage formed through the valvepiston, and with which passage said inclined tube end connects, substantially as and for the purpose described.

JOHN HEATH).
