HENDERSON N. WHITE, OF CLEVELAND, OHIO.

CORNET.

Application filed February 10, 1913.

To all whom it may concern:

Be it known that I, HENDERSON N. VVHrrn, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Comets, of which the following is a specification.

The invention comprises a comet involving more particularly the bell tube and a slide therefor to connect with the first valve, substantially as herein shown and described and more particularly pointed out in the claim.

The object of the invention is to provide the bell tube of a cornet with a pitch-changing slide and to relate and construct said tube and slide in a particular way to connect with the first valve of the instrument, so that the playing of the cornet is made sensitive and responsive, even in scale, and capable of giving the maximum possibilities for delicate tone shading, especially in solo renditions. The relation of this slide to the other parts of the comet is such that the weight of the instrument is perfectly balanced and conveniently handled without strain or effort, giving the impression of exceptional. lightness as compared with other cornets and requiring no especial eii'ort to keep the mouth-piece in sensitive touch with the lips. Free and ample hand-room is also afforded for various comfortable grips and for convenient operation of the instrument. The added length and taper which is given to the bell tube by the double crooks and the A slide therein and the direct and unobstructed passage afforded thereby is a feature which contributes materially to improved tone results. By my improved arrangement of parts the pitch-changing slide is also placed approximately at a central point in the line of the air passage between the mouth-piece and the bell ends of the instrument, and also on the bell-communieating side of all the valves, thereby providing a cornet which will play more perfectly in tune in the different changes effected by the slide than if otherwise located in respect to the said valves.

in the accompanying drawings, Figure 1 is a side view of my improved cornet, and Fig. 2 a similar view from the opposite side. Fig. 3 is an end View of the mouth-end of the instrument, and Fig. l is a sectional view of the first valve approximately on line 44, Fig. 1.

Serial No. 747,255.

The cornet is constructed in part accord ing to accepted standards, that is, it comprises three connected valves 1, 2 and 3, respectively, the casings and pistons together being referred to as the valves. The mouth-pipe l leads directly to the third valve 3 as usual and is provided with a tuning slide 1 having a relatively large bend or crook. The third valve also co-acts with a. valve slide 5, and the valves 1 and 2 are likewise connected with valve slides 6 and 7 respectively as usual. The piston construction of the valves is also of a known type to control the air passages through the instrument, therefore, further description is obviously unnecessary to those familiar with this art.

In this instrument the bell tube is provided with a slide 8 adapted to quickly change the pitch of the instrument a half tone, from B flat to A. To accomplish this in the most practical way, the tapering tube 9 of the bell 10 is bent downwardly on a sweeping curve and projected outwardly or away from the valve 1-, see Figs. 1 and 3. This bend 11 stands therefore at an inclination to the axis of the valve, but in continuing the tube forwardly in the direction of the bell 10, it is bent upwardly into bracing and soldered engagement with the cas ing thereof, especially where turned upwardly to form a crook 12 having the straight sleeve portion 13 for the upper tubular leg of slide 8. This sleeve 13 projects in the direction of the mouth-end of the instrument. The lower leg of slide 8 is housed within the straight tube 14: which is rigidly united with the casing of valve 1, which communicates with the bell, and tube 14 extends parallel to portion 13 of the bell extension but is offset or at one side thereof. The curved connecting portion of slide 8 and its bracing finger loop 15 is thus reversely inclined relatively to that of the large bend 11 of the bell-extension and clearance is thereby obtained to either operate or remove slide 8, see Fig. 3. The sleeve 13 for the upper leg of slide 8 is on a much lower horizontal plane than the straight part of the tube 9 in axial line with the bell, and the valve slide 7 which extends from valve 1 is on a still lower plane at one side of tube 14; and approximately mid way between said tube and sleeve 13. The spaces thus provided between these parallel parts by the peculiar formation and angular relation described give the operator a good and comfortable hand hold and also opportunity to shift or change of grip to meet his particular need. Both the lower and upper sleeves of slides 7 and 8 are pro vided with suitable braces 17 so placed that no hindrance is offered in gripping the instrument or in operating the slides. The so-ealled A slide 8 is also provided with a device to limit its outward movement, said device comprising a rod 18 afiixed to the slide and slidably engaged with the lower fixed tube 14 by a stud 19, a screw nut 20 on the end of the rod serving to adjustably limit its outward movement.

The taper of the bell tube extends from the bell to the beginning of sleeve 13 for the A slide 8 and the double crook and con sequent added length to this bell tube provides an exceptionally long and gradual taper; the double crook in the bell tube and the position of the slide 8 balances the weight of the bell, making the instrument easy to handle and play. If balance of weight is in front of the valves the tendency is to pull the mouth piece away from the lips. The position of the slide 8 makes it more convenient to draw he same toward a person-that is toward the month end, than if projected to the opposite end. i also find that by placing this slide 8 in the bell tube and approximately midway of the length of the air-passage, the tone of the instrument 18 better 1n A,tl1at is when the slide is drawnthan in other instruments known to me. The preferred length of the air passage to make B-fiat is fifty and one-half inches.

The plunger of valve 1 has the usual number of cross aass'a 'es threevall told and in e operation differs in no way from the accepted models.

What I claim is:

A cornet comprising three valves and valve slides, a mouth pipe and bell tube connected with the third and first valves respectively, said bell tube having a large crook portion and a reversely bent crook portion oi smaller dimensions terminating in a straight extension projecting in the direction of the mouth end of the instrument and located between the first valve and the mouth end of the mouth pipe, and the first valve having av straight tube paralleling said extension on a lower horizontal plane and adjacent the lower return bend of the bell tube, and a slide engaged with said. extension and tube located wholly between the first valve and the month end of said mouth pipe and adapted to be withdrawn at the side of the larger crook portion of the bell tube.

in testimony whereof I my signature in presence of two witnesses.
