WIND-INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 329,940, dated November 10, 1885.

Application filed April 13, 1885. Serial No. 162,011. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LoUIs OEsTERLE, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in find-Instruments, of which the following is aspecifcation,

ing drawings.

My invention relates to certain improvements in wind-instruments.

The object of the invention is to improve the arrangement of means for operating the different keys of the instrument; and to that end it consists of certain novel devices and combination of devices, as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figures l and 2 are views, partly in elevation and partly in section, of the keys and their operating mechanism; Figs. 8, 4, 5, and 6, different cross-sections; Fig.7,a detail view of one style of key; Fig. 8, a detail of part of the operating mechanism; Fig. 9, a view showing certain of the keys and their connections; Fig. 10, a continuation of Fig. 9; Figs. 11, 12, sections of Figs. 9, 10, respectively; and Figs. 13, 14, 15, 16, and 17, details of parts.

Like letters refer to like parts in each View.

A represents the instrument to which the improvements are applied.

B represents one of the keys, it being the sleeve, a, mounted upon a stationary shaft, b. Sleeve a is provided at one end with a crank-arm, c, in which is mounted one end of posite end to a crank-arm, e, of a shaft, f, to be referred to.

At the point shown in Fig. 1 there is secured to shaft d a key, C, situated directly above a key, D, with which it is adapted to contact when depressed.

Formed upon the side of the shank of key D is a projection, g, carrying a set-screw, h, larranged to contact with an offset, lc,when the key is depressed,the offset being formed upon a sleeve, Z, securely fastened to a shaft, m.

Secured to sleeve Z is a key, E, thus arranged to be operated whenever compound 4key C D is depressed, but which is free to be operated independently of such compound key.

Secured to shaft j', hereinbefore referred to, is an L-shaped arm, a, in the long arm of which are mounted two set-screws,o p. Screw o is adapted to contact with an offset, q, formed upon one end of a shaft, s, to the opposite end of which a sleeve, t, is secured. Screw p contacts with an offset, o, formed upon one end of a sleeve, w, loosely mounted upon shaft s. A key, F, is secured to sleeve t, and akey, H,to sleeve w.

By the arrangement of parts as thus far described it will be seen that whenever the compound key C D is depressed the key B is operated through the medium of rod d, crankarm c, and sleeve c; keyE is operated through the medium of set-screw h and offset k,- key F through the medium of rod d, crank-arm c, shaft f, arm n, setscrew q, shaft s, and sleeve t,- and key H is operated through the medium of shaft d, crank-arm e, shaft f, arm n, setscrew p, offset o, and sleeve w, arrangement being thus made for the operation of fivekeys by the simple depression of one compound key.

As before mentioned,the arrangement of key E with respect to compound key C D is such that it may be operated independently of such compound key.

Formed with the sleeve w are two bearings,

x, for a short shaft, y. Keyed upon shaft gis akey, G, the shank of which is provided with a rearward extension, a, suitably curved to partly surround the sleeve w. By this arrangenient, should key G be depressed, extension a will contact with sleeve w, the bearings .r forced to describe the arc of a circle, sleeve w partly revolved, and key H operated; but should the pressure be applied to key H there will be sufficient play to the bearings to allow of such depression without operating key G, the two keys being on different centers.

It will be understood that keys G H,when not operated upon,are held elevated by aspring, b.

The key D, hereinbefore referred to, is secured to a sleeve, c', mounted loosely upon a shaft, mf. Formed upon sleeve c are two bearings, d', for a short shaft, e. Mounted upon shaft c is a key, K, and also an arm, f, which is curved to partly surround sleeve c, this arrangement of parts being substantially IOO similar to the arrangement described in connection with keys G H, the only difference being that, instead of forming the shank of key K with a rearward extension similar to a of key G, the arm f is provided, the result being the same, but this arrangement being desirable in order to shorten elevating-spring g as much as possible. By this arrangement it will be seen that when key Kis depressed key D is operated through the medium above described, and key E through set-screw 7L and offset lc, three keys being thus operated from one, while at the same time key D may be operated independently of key K.

Key P, to be hereinafter referred to, is operated by the fourth finger, and should it be on the same level as the keys operated by the other fingers of the same hand its operation would be difficult, as the movement of that finger is not free. To obviate this difficulty I mount, upon the upper face of the key K, and a key, L, to be referred to, and between which two keys P is located, a knob, K', provided with a suitable socket, into which a screw, 7L', is inserted, as shown in Fig. 7. These knobs are ou a slightly higher plane than the key P, and means thus provided for the free working of said key P by the fourth finger.

L represents one of the keys loosely mounted upon the shaft b, before referred to. Formed upon the shank of key L is an arm, k', in which is mounted aset-screw, Z. Screw Z is adapted to contact with an offset, m, formed upon one end of the shaft m, to the opposite end of which sleeve Z is secured, the key E being mounted upon said sleeve, as before mentioned. By this arrangement it will be seen that key E may be operated from key L, but at the same time is free to be operated by compound key C D without affecting said key L. Situated directly above key F is a key, M, secured to a shaft, a, said shaft having bearings at one end in an arm, o', loosely mounted upon a shaft, p, upon the opposite end of which a crank-arm, q, is formed, to which reference will be made. Shaft u at the pointshown is provided with an arm, bwhich projects over a key, N, and in which is mounted a set-screw, s. Key N is fastened to the shaft p. At its Opposite end shaft a is secured to a crank-arm, f, formed upon one end of a sleeve, o', upon the opposite end of which a similar arm, w, is formed.

Mounted in crank-arm w is a shaft, x', which at its opposite end is secured to a crank-arm, y', formed with a sleeve, a2, to which a key, O, is secured. By this arrangement, when compound key F M is operated, the key N is operated through the medium of shaft a', arm b?, and set-screw s', while key O is also operated through the medium of shaft a', crank-arm t, sleeve c', arm w', shaft x', arm i and sleeve a2.

P represents a key secured to a sleeve, c2, loosely mounted upon shaft m. Secured to sleeve c2 is a crank-arm, d2, in the opposite end of which a shaft, e2, is mounted, said shaft being secured at its opposite end to the crankarm g', before referred to. At that end of shaft e2 where it has bearing in crank-arm d2 it is provided with a tapered opening, f2, Fig. 8, into which a set-screw, g2, is inserted. By this arrangement of parts,when key P is depressed, the keyN is operated through the medium of sleeve c2, crank-arm d2, shaft el, crank-arm q', and shaft 19'; but when key N is operated shaft e2 is allowed sufficient play, because of opening f', to avoid operating key P.

Q represents a thumb or first-finger key near the front end of the instrument, secured to a sleeve, h2, loosely mounted upon shaft p', such key being entirely independent.

To provide means for operating key N from the opposite side of the instrument, I provide the shank of such key with a tooth, k2, Fig. 3, with which a similar tooth, Z2, is adapted to contact, the latter being formed upon the shank of a ngerlever, R, mounted upon a. short shaft, m2. (Shown in Figs. 9, 15.) The key H is provided with a tooth, n2, to contact with a tooth, o2, formed upon a short shaft, p2, and to the opposite end of which a finger-lever, S, is secured.

T V represent two keys, the two first on their side of the instrument. Key T is mounted upon a shaft, g2, having bearings in suitable brackets, r2, and having at its opposite end an arm, s2. Arm s2 occupies a position directly above au L-shaped arm, t2, secured to a shaft, v2, said shaft mounted at one end in one of the brackets r2. Secured to shaft o2 about midway its length is a fingerlever,\V, by depressing which key T is operated through the medium of shaft o2, L-shaped arm t2, arm s2, and shaft q2. Mounted upon shaft q2 is a sleeve` ur, to one end of which is secured key V. Secured to the opposite end of this sleeve is an arm, which occupies a position directly above the free end of an L-shaped arm, i 2, secured to a sleeve, a3, mounted upon shaft o2, and carrying fingerlever x, the key V being thus operated by sleeve c3, arms if x2, and sleeve wz.

Finger-lever W was described as situated midway of shaft c2, and for convenience in playing I secure to the end of said shaft au additional finger-lever,Y, from which keyT may be operated.

To obtain a similar convenience in operating key V, I employ a finger-lever, A', mounted upon a sleeve, b3, said sleeve being` provided at its opposite end with an L-shaped arm, c3, above the free end of which an arm7 d, is located, said last-named arm being secured to the sleeve a3.

B B2 represent two keys mounted upon iudependent sleeves caf, to the latter of which a fingerlever,C, is secured, by which arrangement either key may be operated separately, while at the same time the position ef lever C renders the working of the two at the same time easy.

Formed with offset q, before referred to, but upon the opposite side ofthe shafts, is a tooth, g, with which a similar tooth, h3, formed with IOO IIO

arm x2, is adapted to Contact, this arrangement serving to operate key F, whenever key T is operated from its finger-lever. This arrangement is shown in Fig. 6.

What I claim is- 1. In a wind-instrument, the combination, with a key thereof, of a second key situated directly over the rst and arranged to contact therewith, the two keys moving from the same center, as set forth.

2. In a wind-instrument, the combination, with a key mounted upon a sleeve,with which are formed suitable bearings, of a second key secured upon a shaft mounted in said bearings, and a curved arm encircling the sleeve, as set forth.

3. In a Wind-instrument, the combination, with a key thereof, of a shaft provided with a LOUIS OESTERLE.
