PIPE-ORGAN.

SPECIFICATION forming part of Letters Patent No. 468,509, dated February 9, 1892.

Application filed December 6, 1890- Serial No. 373,731. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN Soorr VoTEY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Pipe-Organs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in pipe-organs; and it consists in a novel arrangement of parts operated by and in conjunction with the stops of the organ, whereby a corresponding series of lovers may be pneumatically actuated to set a series of plungers in a cylinder or revolving agent for the purpose of arranging them in such manner as will enable the operator, when subsequently executing the music, to readily and easily produce any desired combination of registers or any number of consecutive combinations of registers, according to the music-score, by a manipulation of the fingerrail, and a further arrangement of parts operating in concert therewith whereby during the execution of the music the stops that correspond with each consecutive combination of registers are pneumatically adjusted when the cylinder to produce a certain combination of registersby pneumatic action, and to further provide for pneumatically actuating and locking the corresponding stops when said combination is produced, at the same time operating the slides that control the several registers to be used to do away with the intricate and complicated mechanism usually employed for this purpose and obviate the noise incident to its operation, which is in some cases so great as to seriously impair the tone of the instrument. This object is attained by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section through that portion of an organ containing my improved features. Fig. 2 is a plan view of the parts shown in Fig. 1.. Fig. 3 is a longitudinal section on dotted line 1 1 of Fig. 2. Fig. 4 is a transverse section on dotted .line 2 2 of Fig. 2, looking to the right.

The drawings illustrate my improved features as applied to a three-manual organ; but they may be adapted to an organ of any number of manuals.

Referring to the letters and figures of reference, A indicates the ordinary frame of the organ, having on the front thereof the keyboards B B' B", provided with the keys 0, that are connected to operate in the usual manner.

A indicates a cylinder mounted to rotate in the frame of the organ, and by suitable mechanism (not shown) is placed under the control of the operator. Said cylinder is provided with a series of plungers '12, mounted to slide on pins 0, set in the circumferential grooves n in the periphery of the cylinder and arranged in longitudinal rows therein, which is common. The plungers n are adapted to slide out and in on their respective pins 0 and are provided with a peripheral groove 0', adapted to receive a longitudinally-working slide 15 to lock said plungers in their innermost position, said plungers being locked in their outermost position by the slides 15 passing between their inner shoulder and the periphery of the cylinder A. This arrangement permits all of the plungers in any of the longitudinal rows to be locked by a single slide, either in their outer or inner position, or with part of them out and part of them in, as shown by the lower line of plungers in Fig. 4. It is by the previous arrangement of these plungers in the cylinder A, according to the music-score, that the operator is enabled to readily and easily produce any desired combination of registers when executing the music, as hereinafter set forth.

The setting of said plungers in the cylinder is accomplished in the following manner: Extending through the front of the organ, on each side of the key-boards, are a series of stops D, that are adapted to slide horizontally.

A continuation of said stops D is effected by coupling the rods D thereto, the rear end of each of said rods passing through air-chamhers I) 1), formed in the case D, as shown in Fig. 1, said rods having on the end thereof the convexed buttons at a, that bear against the outer faces of the flexible diaphragms (Z (Z of the respective air-chambers Z) b. By

this arrangement, when air under pressure is admitted alternately to the chambers Z) b through the pipes E E, the respective diaphragms (Z d of said chambers will be alternately blown out, and said diaphragms hearing against the buttons a a of the rods D will cause said rods to reciprocate longitudinally and move the stops D out and in for purposes hereinafter described.

Mounted on the rear ends of each of the stops D is an inclined arm f, adapted to engage the lower ends, respectively, of the vertical stems f, carrying on their upper ends the valves 2?, adapted to close their respective portsf in the wind-chest F, said stemsf' also carrying the disk t, adapted to close the outer opening of the portf when the valves 75 are raised, whereby by drawing outward on the stops D the arm f thereon will operate the stem f to raise the valve 6 in the windchest F from the port f, when the wind will pass through said port into the pipe F, communicating therewith, and through said pipe into the air-chamber 7t in the chest F. Said air-chamber communicates with a flexible diaphragm h, that bears against the button a on the upper end of the vertical rod h, said rod passing through the air-chamber h and the air-chamber m of the case G, and, extending through said case, is coupled at its lower end to one end of the horizontal lever H, which is fulcrumed near its longitudinal center to a support H, the opposite end of said lever carrying a friction-wheel H and being held up by a spring t, which causes said wheel to normally bear against its corresponding plunger 01 when said plunger is in its innermost position in the cylinder A, by which arrangement, when wind is admitted to the air-chamber 7L through the pipe F, as before described, the diaphragm h will be blown out, actuating the rod h and raising that end of the lever H to which its lower end is attached, depressing the opposite end of said lever upon the spring i, and carrying the wheel H down, when its corresponding plunger n will fall to its outermost position in the cylinder A, as shown in Fig. 1 and at 'n in Fig. 4. It will be understood that the number of plungers n in the longitudinal rows on the cylinder A correspond with the number of stops D of the organ and that each stop operates a separate lever H to set its corre sponding plunger, which enables the operator, by drawing out the respective stops D, to set their corresponding plungers it in the cylinder A to produce the first desired combination of registers. \Vhen said series of plungers are so set, the locking-bar or slide i is actuated to lock said plungers in their respective positions. The stops D that were drawn out to set said combination are then shoved in, when the valve twill close the upper end of the portf, cnttingotf the wind from the air-chamber h, the wind therein being permitted to escape through the lower end of the port f, opened by the dropping of the disk i, thereby relieving the lever H. The cylinder A is then revolved by suitable means to bring the succeeding row of plungers 01 directly over the series of wheels carried by the levers II, when by again drawing out the stops said row of plungers may be set for the next combination of registers, according to the music-score, when said plungers are looked, as before described, and the cylinder A again revolved to bring another row of plungers in position to be operated on by the levers I l, and so on until all of the horizontal rows of plungers in the cylinder have been set, or as many of them as is necessary to pro duce consecutively the different combinations of registersin the music to be executed. The cylinder A is then revolved until the row of plungers a set for the first combination shall stand directly over the wheels ll" of the levers H. The music may then be executed in the ordinary manner, and when it is desired to produce the first combination of registers set the operator strikes upon any one of the finger-rails I, that extend along each manual of the organ, conveniently above the keyboards thereof, (see Fig. 2,) and the inner ends of which are pivoted at a: to the organ-frame and which are connected by the coupling-rod I to the outer end of the lever 1",that is fulcrumed at its longitudinal center to the post Q, (see Fig. 3,) the inner end of said lever I being coupled to the vertical stem 1*, carrying on its upper end the valve .9, adapted to close the port 5 in the wind-chest F, said stein also carrying near its center the disk 3, adapted to close the outer end of said port when the valve 3 is raised, whereby, when the operator strikes the finger-rails I,the lcverl is operated to raise the valve 3 in the windchest F, when the wind will pass through the port 3 into the pipe G, communicating therewith, and through said pipe to the air-chamber m in the case G, in which is located a two-way valve P, controlling the ports 11 t", that communicate, respectively, with the pipes E E. This air-chamber m is common to all the valves P of the series of levers H, the position of said valves being determined by the position of the plungers n in the cylinderA. For instance, those plungers that have been set in their outermost position will bear upon the wheels 11 of the levers H, thereby depressing that end of said lever and raising the valve P, connected with the opposite end thereof, as shown in Fig. 1, which will open the porto, permitting the wind to pass through the pipe E to the air-chamber b and expand the diaphragm d, which will blow out its corresponding stop D and raise the valve 2i in the wind-chest F,when the wind will blow through the pipe F into the air-chamber 71 and raise the diaphragm It, thus drawing upward on the rod h and locking the valve P and lever H in their respective positions. At the same time the wind will pass from the chamber h,- through the pipe J, into the air-chamber 0 of the case N and raise the flexible diaphragm 0, which bears against the button 0" of the rod 11;, on which is mounted the two-way valve 10., controlling the ports i i in the windchest J, through which said rod passes, thereby lifting said rod and raising said valve from the port 1'" when the wind will pass through the pipe K and expand the bellows L, which, being connected to the twin bellows L by the rods 2, will cause said bellows L to collapse and actuate the slides that control their respective registers, (which construction is not shown, as it will be readily understood.) The blown out, when the desired register or combination of registers will be produced, ac-

cording to the previous arrangement of the plungers n on the cylinder A. After the first combination has been used the cylinder A (by suitable mechanism,'not shown) is revolved so as to bring the succeeding rows of plungers 'n directly over the wheels H, carried by the series of levers H, when the plungers n that are set in their outermost position will bear upon the wheels H" and depress that end of the lever H on which they are mounted, actuating the opposite end of said lever to raise the valve P to open the port 1, as shown in Fig. 1, and the spring 5 will force the wheels 'H up against the plungers n, that are set in their innermost position, as shown at n in Fig. 4, thereby drawing downward on the rod 71:" and actuating the valve P to close the port 1 and open the port '0, the parts being then in position to produce the next combination, the operation continuing in the same manner until all the combinations set have been used in their consecutive order. When the wheel I is resting against a plunger in its innermost position, the valve P will close the port '1) and open the port Q2, so that when the finger-rail is struck wind will be admitted through the pipe E to the air-chamber b, which will blow out the diaphragm d, drawing in its corresponding stop D, which is thereby locked in that position while that combination is being used, it being undcrstoodthat it is the plungers set in their outer positions only from which any effect is-obt-ained.

It will be observed that the ports 1; o in the wind-chest G are provided, respectively, with the vents 1 2, adapted to be closed by the disks 3 4, mounted on the rod h, the position of parts being such that when the valve P is raised to admit wind to the chamber to blow out the diaphragm d the disk 3 will be raised from the vent 1, which permits the air to escape from the chamber 7) through the pipe E as the diaphragm d is drawn in, (shown in Fig. 1,) and when the valve P is down, opening the port o to permit the wind to pass through the pipe E and blow out the diaphragm d, the disk 4 will be carried away from the vent 2, permitting the air to escape from the chamber 1) through the pipe E as the diaphragm d is drawn in. It will also be observed that when the valve t is closed the disk 25 is moved away from the outer end of the portf, which affords a vent for the airchambers h and 0 through the pipes F and J, permitting the diaphragm 0' to collapse and the valve 10 to fall, opening the port 6, when the wind will pass through the pipe K to the bellows L, expanding said bellows and collapsing the bellows L, as shown by dotted lines in Fig. 1, when said parts are in position to again actuate the slides to produce the register controlled by its corresponding stop.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-
