' MUSICAL -WIND INSTRUMENT.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed October 31, 1910. Serial No. 589,956.

To all whom it may concern:

Beit known that I, HARRY B. JAY, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Musical "Wind Instruments, of which the following is a speci fication.

This invention relates to improvements in musical wind instruments, and relates particularly to tuning and quick-key change devices for trumpets, horns and like instruments.

I have shown in the accompanying drawing my improvements adapted to a trumpet of a simple keyless type.

It will be obvious that the improvements are applicable to various forms of musical instruments of the trumpet and horn type having tuning slides or crooks.

The main objects of this invention are: First, to provide in an instrument of the class described a combined quick key change or shift and tuning device. Second, to provide a device for the purposes stated, which is very simple in structure and easily adjusted.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.-

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a side .view of an instrument embodying the features of my invention. Fig. 2 is an enlarged detail section, parts being broken away to better show the structure, with the tuning slide or crook collapsed, its extended position being indicated by dotted lines. Fig. 3 is a detail view, showing the stop member 8 adjusted to a different position from that shown in Fig. 2. Fig. 4 1s a cross section taken on a line corresponding to line 44 of Figs. 2 and 3. vFig.v

- ters refer to similar parts throughout the several views and the sectional views are takenlooking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the instrument 1 illustrated is a common type of trumpet, the same being without keys or valves excepting the water valve 2. As before stated, my improvements are applicable to any in strument of this type, having a tuning slide or crook. The tuning slide or crook 3 telescopes with its coacting parts 4 and 5, the crook being provided with 'a finger piece 6 for moving it. On the member 4 is a stop member 7, while on the slide member 3 is a coacting rod-like stop member 8. The engaging part 9 of the stop member 8 is preferably a pair of nuts threaded thereon, one nut serving as a locking nut for the other. The stop member 8 is preferably adjustably mounted on the slide 3 by means of the clamp 10, which embraces the slide and is secured by means of the clamping screw 11 (see Fig. 4). This clamp, with the parts arranged as in Fig. 1, serves as a stop to limit the collapsing movement of the slide, and the stop member 9 coact-ing with the member 7 on'the section 4, limits the extending or outward movement of the slide. The stop members being slidably associated, the tuning slide can be shifted within the limits of the stops, thus providing the quick change as, for instance, from A to B fiat, or otherwise, as may be desired, the stops being properly adjusted to secure the desired intervah By adjustably mounting one of the stop members, as the stop member 8 in Fig. 1, tuning is possible.

In the modified construction shown in Fig. 5,'the'stop member 8 is secured in the arm i2 on the section 4 by means of the set screw 13. The stop member is, in this embodiment, provided with a second engaging member 14, which limits the movement in one direction, the engaging member 9. limiting the movement in the other direction, as in the structure shown in the other figures.

Other modifications will no doubt suggest themselves to those skilled in the art to which this invention relates.

I have illustrated and described my improvements in detail in a satisfactory embodiment, although it will be obvious from the forms of the Invention shown, that it is capable of considerable variation in structural details.

Having thus described my invention, what I claim as new and desire to secure by Let Lei-s Patent, is:

1. rm instrument or the class-described,

comprising a tuning slide and. its coacting telescoping part, a stop on said coaeting part, and a second stop member slidably asso ciated with said stop and having; an adjustable stop engaging part and being provided with a clamp by which it is adjustably mounted, on said slide, said clamp beimg, adapted to serve as a stop to limit the col lapsing movement of said slide.

F one of said sections, and a second stop memher JlOVfllJly associated with said stop, said secorul. stop member being provided with an adjustable stop engaging member and with a supporting clamp whereby it is adjustably mounted on the other of said sections.

instrun'ient of the class described comprising a tuning slide member and its (:0- acting telescoping member a stop on one of said members, a second stop mounted on the other member to be adjusted thereon to limit the movement of said slide in one direction, said second stop member being provided With an adjustable stop engaging part.

5. An instrument of the class described, comprising telescoping sections, a stop on one of said sections, a second stop member adjustably mounted on the other or" said sections, said second stop member being provided with an adjustable stop enqaging part.

6. An instrument of the class described, comprising a tuning slide member and its coacting telescoping men'iber, a stop on one of said members, and a second stop member adjustably mounted on the other of said members, said second stop member being provided with an adjustable stop-engaging part.

7. An instrument of the class (lGSCIlbCd, comprising a pair of telescoping sections, a stop on one section, and a second stop member movably associated with said step and having an adjustable engaging part, said stop member being adj ustably mounted on the other section to limit the collapsing move ment of the telescoping sections.

In witness whereof, I have hereunto set my hand and seal in the presence of two Witnesses.
