SPECIFICATION forming part of Letters Patent No. 664,434, dated December 25, 1900.

Application filed March 30, 1899. Serial No. 711,055. (No model.)

struments that are furnished with valves or pistons; and the said improvements comprise a novel construction of valve and valve-operating mechanism having for its object to obtain a quick action with a short stroke or movement; also, a certain novel construction of adjustable shank and mouthpiece by means of which theinstrument is tuned in harmony with other instruments and higher notes and octaves are produced with less eiort and without materiallyincreasing the pressure of the lips upon the cup.

The invention includes also a novel means or device for producing a tremolo effect of any desired duration at will.

The following description explains atlength the nature of my said improvements and the manner in which I proceed to construct, produce, and apply the same, reference being had to the drawings that accompany and form part of this specification.

A indicates the bell, and A the neck and principal tubular portion of the instrument.

B B' BL are the valve casings or chambers.

C is the shank, and P the mouthpiece.

E E E2 are the tubes that form connectionpassages between the valve-chambers and the neck or body of the instrument.

F F F2 are loops or extension-tubes that are connected to the passages E E/ F.2 through the valves to increase the length of those passages, and thereby change the notes.

G is a damper-valve placed in the neck A', and Gf a lever on the outside connected to the valve for throwing it into and out of action.

H H are water-valves in the bends ot' the curved tubes E E' E2 for draining the water of condensation from the valves and passages.

The construction and operation of the piston-valves will be understood more clearly by referring to Figs. 6, 7, and 8 of the drawings. The casing bX is tubulaiand of cylindrical shape, in two parts, with the removable top portion b2 united by a screw-joint b3. The main outlet-aperture in each casing is located at the bottom, to which the tubular conductor E is joined, and the main inlet b4 is located in one side. In addition to these apertures there are two openings b5 b, to which is connected a loop or extension-tube F. One of the lastmentioned openings is located below, and the other above, the line of the inlet b4. The piston B controlling these openings is in form a hollow cylinder open at the bottom, but closed at the top with an aperture 197 in one side, and at right angles,or tl1ereabout,to that aperture a cross-passage bs, leading directly through the body, this passage being separated from the open lower part of the piston by a diaphragm b9. The piston has a longitudinal sliding movement and also a short rotary movement in that portion of the casing where the apertures b4 b5 are located, so that IOO in one position it closes communication between the inlet h4 and the outlet h5 to the extension-tube F and establishes a direct passage between the inlet b4 and the outlet blo in the bottom of the valve-casing, while in another position it connects the inlet-passage bL with the outlet b5, and thus throws the loop or extension into operation to increase the length ofthe conducting-passage. The movement of the piston to throw it into these positions is effected by the following means: A cylindrical barrel d, of smaller diameter than the piston BX, is rigidly fastened to the head of the piston, and a rod or spindle d@ having its lower end fixed in the closed top end of the barrel,ex tends outward through the end of the valve-casing. Over this rod a hollow cylindrical plunger D is fitted to work smoothly up and down through a circular opening in the cap or top of the casing bx, and on its upper end, outside the casing, is set a head or key D. The spindle working through au aperture in the lower end of the plunger extends through the center of that piece and is seated in a conical bearing d2 on the under side of the head D', the end of the spindle being pointed to fit and turn smoothly in that bearing. D3 is an elastic cushion surrounding the plunger inside the casing, and D4 is .fore the top section B is screwed on.

a cushion on the lower side of the head to prevent contact of the metallic surfaces with each other in the stroke of the plunger, and thus overcome the noise and shock incident to the movements of the keys. In the sides of the barrel are cut diagonal slots d5 CZ, diametrically opposite to each other and having' a pitch or inclination with respect to the axis of the barrel, and d6 is a fixed pin or bar having its ends fixed in the sides of the valvevcasing and extending through the slots d5 and diametrically across the barrel and the casing.

K is a helical spring having one end secured to a fixed point X on the top of the piston B and at the opposite end attached to the crossbar (Z6. The slots d5 are located diametrically opposite to each other, and they are inclined at such an angle with respect to the axis of the barrel that a quarter turn or rotation of the piston is produced by a short stroke or longitudinal movement of the plunger D. The ends of the cross-bar d6 are set into slots in the body of the casing at the joint b3 be- This construction is illustrated in Fig. 7. In the normal position of the piston the key is held up in its highest position by the spring K, and the aperture 197 stands in line with the inlet b4, so that the extension-loop is cut out and there is direct connection through the piston between the inlet b4 and the outlet bw in the bottom of the valve. This position is shown in Fig. 8. From this position when the key is depressed the pistou is forced down and atthe same time is rotated about a quarter turn, so that the cross passage 58 is brought in line with the aperture b4 and the passage across the piston is brought in line with the aperture bf in the valve-casing. In this position, which is shown in Fig. S, the extension-loop F is made a part of the conductor between the mouthpiece and the bell, and the passage is increased in length by that amount as long as the key is held down. This construction of valve-operating mechanism gives a quick and full throw and return of the valve with a short stroke and light pressure of the key.

In the present arrangement of keys, as I have illustrated in Figs. l, 2, and 5, where the improvements are applied to an instrument with three keys, the mouthpiece P is connected directly with the first valve B, and the tube E from the bottom ot' that valve is connected with the inlet of the second valve B', while the tube E from the outlet at the bottom of the second valve B is connected to the inlet b4 in the side of the third valve B2, to the bottom of which the neck or main portion of the body A' is connected by the tubular portion A2. The wind-passage through each Valve is increased in length by a separate loop or extension to each valve-casing. In the normal position of the pistons, with the keys elevated, the windpassage from the mouthpiece P is open and continuous through all the valves in the order of their connection with the bell, and only when a key is depressed is the length of this passage increased and the musical sound varied or modilied. The shank carrying the mouthpiece P on the outer end is formed of the stationary tube GX, joined at b4 to the casing B of the Iirst valve, and the sliding section C2, that telescopes on the tube C and is locked on it by a bayonetslot hand a pin orstud 7L'. (See Fig. 2.) The section C2 is composed of an ou ter tube m and an inner tube m of smaller diameter, the two tubes being united near the outer end of the shank at the screw-coupling M, that joins the mouthpiece to the shank. The stationary tube is fitted to slide closely into the space between the two tubes m m', so that while the shank is readily lengthened or shortened by sliding one part on the other a smooth passage without crevices or openings that will let out the wind is secured. slots 7L are formed in the outermost tube fnl., and the pin 7L' to engage the slot and lock the sliding tube is fixed on the outermost conductor E, as seen in Fig. 2. By partially rotating the sliding section C the pin is thrown out of the locking-recess in the slot and brought into the straight portion of the slot, so that the shank can be increased or reduced in length, as desired, after which the section C2 is locked by turning it back with the same rotative movement. A close joint between the outer tube m of the sliding section and the stationary section CX is produced by the collar M3 on the end of the tube m. This construction of extensible shank is similar to that described and shown in my former Letters Patent, No..593,690, issued to me ou the 16th day of November, 1897. The present The bayonet- IIO www... www

mouthpiece differs from the construction embraced in that patent, however, in the peculiar position and arrangement of the tongues for regulating the area of the orifice in the cup and in the means of adjusting the same. The presentim provements relate to the means of fixing the mouthpiece on the shank and the means provided for regulating the pitch of a note by varying the pressure of the lips against the cup, and the same have for their object mainly to secure a delicate adjustment of the mouthpiece without changing or affecting the depth or area of the cup as the outer shell is moved on the cup, and thereby affect in some degree the quality of the tone produced. In the present improvement one, two, or more tongues I are placed inside this shanksectionm with their tapering ends I extending into the passage px in the cup and with their opposite ends attached to the tube m/ by screws. Two of these tongues set diametrically opposite to each other are found to answerwelland give good results. Each tongue is made with a gradual taper from the broad end to the point which is set into the narrow part of the passage 19X, and at the broad end it is fastened to the inner tube by a screwj, the tongues having greater thickness at this end to produce the offset portion p5, so that the tongue stands clear of the inner tube and a space is afforded for the tubular shan k P ofthe mouthpiece to pass between the tongue and the tube. A spiral spring R, placed around the shank between the end of the inner tube m and a shoulderI p0 on the base of the cup, acts to keep the mouthpiece in a normally open or free position with the points of the tongue clear of the orifice. This spring is covered by a cylindrical sleeve M, which is' secured to the base of the cup at one end, and at the other end is screw-threaded exteriorly to take a coupling ring or band M. This lastnamed piece unites the mouthpiece to the external tube m of the telescopic section C2, the joint being formed by an inwardly-turned flange S on the coupling M and an outwardlyturned flange S/ on the end of the tube. This construction is shown in the detail sectional Views, Figs. ll and 12. The function of this coupling is to set and regulate the position of Athe tongues I in the tapering passage with respect to the orifice in the bottom of the cup, and thus increase or reduce the area of the orifice accordingly. Of the two adjustments thus provided the screw-coupling enables the tongues to be set into or out of the contracted portion of the tapering passage to a greater or less amount and their working position adjusted by hand, while the lnovement of the cup itself under the pressure exerted against it by the lips of the performer sets the tips of the tongues into the orifice to agreater or less amount, according to the pressure exerted.

In the adjustment of the tongues by hand they are set into or out of the lowermost portion of the passage a greater or less amount at the time of tuning the instrument to the required pitch, and by the pressure exerted against the cup by the lips of the performer the tips of the tongues reduce the area of the orifice, so that high notes in one or two octaves can be easily played.

G is a dam per-valve placed within the neck of the instrument and connected with a key G' on the outside. This piece is placed within the contracted portion of the bell and is fixed to the inner end of a short shaft Gg by a screwthreaded stem G3 on the valve G and a threaded socket in the end of the shaft, the outer end of the shaft carrying the key-lever G/ for turning it. A socket and bearing Gifor the shaft is formed on the side of the neck A', anda support G5 is fixed on the tube E to carry the outer end of the shaft. The valve is a thin disk, in diametersomewhat less than the internal diameter of the surrounding tube, so as to leave an annular space between the rim of the valve and the tube. It is mounted to make about a quarter-turn on the axis formed by the stem at one side, so as to stand either at right angles across the tube or else in line with the tube to stand edgewise in the passage. In the first-mentioned position the disk closes the passage, except for the annular space left between the edge of the disk andthe surrounding tube, and in the other position at right angles the disk is presented edgewise to the body of wind. Accoi-ding to the position in which it is set, therefore, the disk operates either to reduce or to modify the intensity of the sound, which it does without affecting the pitch or quality, or to leave the passage unobstructed and practically of full area, so as not to affect the volume of sound. It is held normally open by a spring T on the shaft, and it remains closed as long as the lever G' is held back.

IOO

The soi-ing is a flat stri T confined at one end in a splitstud iX on the bracket G5, with its free end inserted through a slit in the rim of a circular head t2, fixed on the shaft G2. The tendency of this spring to return to a straight line when bent sidewise by the rotation of the shaft causes it to throw the valve open when the finger is removed from the lever G". The end of the spring within the part t2 is furnished with a T-head t3, that prevents it from drawing out of the slit and forms a stop to limit the rotation of the shaft G.

If it be desired to hold the damper in closed position for any considerable time, the lever G can be locked against the side of the valvecasing by a hook Z or other suitable catch provided on the first casing, as indicated in Fig. 2.

The dam per is readily detached and removed from the bell by unscrewing it from the shaft S.

A tremolo effect in the tones of the instrument is produced at the pleasure of the player by giving a rapid rotary motion to the damper G, and in connection with this part G a means of imparting a rapid motion to it and for placing this motion under the control of the player IIO ' is provided on the instrument, so that it can be brought into action and stopped at will by the simple movement of a nger.

The construction of the mechanism for rotating the damper and controlling its motion is illustrated in Figs. 14- and 15 of the drawings. A pinion or small gear V, fast on the shaft G3, connects that part with a Wheel W of much greater diameter, the proportions in the present construction being about one to ve, and the rims of the two wheels are caused to engage each other either by spurteeth or elastic rims. One wheel is in constant engagement with and is caused to drive the other when rotated. Power is applied to the large wheel by means of the lever W', pivoted at W2, and a connecting-rod W4, attached to the free end of the lever and to a crank W5, fast on the axis of the large wheel. Oscillating movement of the finger-lever thus imparts rotary motion of the damper-shaft at a velocity considerably higher than the crank-shaft.

The dead-centers in the rotation of the driving-crank are overcome or prevented by an arrangenent of two springs Y Y, which are at-tached to stationary points-y y diametrically opposite, or nearly so, to each other and to a common crank Y2 on the end of the axis of the wheel opposite to the driving-crank, the two cranks being set at such angles with respect to each other that when the drivingcrank stands on the horizontal center line the crank Y2 on the opposite side of the wheel occupies an angular position either above or below the horizontal center line, according as the driving-crank is on one side or the other of the axis.

A stop-lever Z on the casing U, that covers the wheel, is provided for arresting the motion of the tremolo mechanism and throwing it out ot' action at will. The stop-lever Z works through the casing and'engages a slot Z2 in the wheel W when it is pressed in by the finger, or by a contrary movement it is disengaged from the wheel, and the latter is allowed to act as the finger-lever Vis vibrated. The slot Z2 is of such length that the movement given to the wheel W in one direction when the stop engages the slot will open the damper G or in the opposite direction it will close the damper, so that the same fingerlever V is made to operate both as a tremolo and to produce piano or forte effects at pleasure.

VVater-valves H are provided on the tubes E at the lowest part of the bends, from which outlets all the valves and tubes, including the loops F, are thoroughly drained.

Among the peculiar features of the present construction should be mentioned especially' the position of the valves, the arrangement of the bends or members connecting the valves with the body of the instrument, and the combination of the whole with the adjustable shank. The valves are set in stepped position instead of on a straight line, so that the keys stand in position to accommodate the fingers of the player, and the hand is not thrown out of natural position or required to be held in a cramped state. As tuning slides and elbows are dispensed with and the tubes are bent and carried in free curves from the curved neck or elbow ot' the main portion of the instrument around to the end of the valvecasings, the entire center is left open, so that the arm of the player can be readily passed through the open center, and thus the instrument can be hung on the arm or from the shoulder when not in use. This is of special advantage in instruments of the larger sizes from alto-horns upward, in which class of instrument the player can carry it on the left shoulder, with the arm passed through the open center and with the bell hanging down, while by raising and throwing the bell forward into a horizontal position the instrument is brought to position for use without removing it from the left arm. The rear bends or elbows of the curved tubes E are connected by slip-joints E to the portions that are directly attached to the valve-casings, so that longer or shorter elbows or curved portions can be substituted, as conditions may require in timing the instrument to dierent keys.

The manner ot' arranging and connecting the valves, the bell, and the mouthpiece, as above described' and shown in Figs. 1, 2, and 6 of the drawings, is productive of many advantages, especially in the construction of the larger kinds of instruments, for it will be noticed that the bell and the mouthpiece are located on a straight line, with the bell extending horizontally in front of the player, and especially the bends or coils of tubes that connect the valves and the mouthpiece to one another and to the bell are so arranged that a clear opening is afforded through which the left arm of the player can be introduced. Thus the weight of the instrument can be thrown upon and borne by the left shoulder with the bell presented to the front, and when the instrument is not in use it can be suspended from the shoulder with the bellhanging down. These features are secured, first, by the construction of the valves and the position in which they are set, whereby the connecting-tubes are carried from the bottom of the valve-cases with smooth and gradual bending, and, secondly, by dispensing with slides and crooks or extensible sections between the valve-cases and the'bell or the mouthpiece.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cornet, or similar wind instrument, the combination of the bell, the straight shank carrying a mouthpiece on the outer end, valve-cases having wind-apertures in the bottom ends and sides, and the windings or curved tubes connecting the bottom end of IOO IIO
