SPECIFICATION forming part of Letters Patent No. 488,559, dated December 27, 1892.

Application filed August 18, 1892. Serial No. 443,405. (No model.)

To all whom t may concern:

Be it known that we, CHARLES S. HAsKELL and WILLIAM E. HAsKELL, both citizens of theUnited States, residing` at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Organs, of which the following is a specilication.

The principal objects of our invention are first, to provide the swell pedal with simple and efficient attachments which normally operate when the swell is being let on to pneumatically push out stops one after another until all the stops are out, and which normally operate when the swell is being let off to pneumatically push in stops in a similar manner, whereby the power, tone and quality of the swell are enhanced and perfected; second, to provide simple, durable and efficient pneumatic and mechanical draw-stop actuating apparatus and complemental devices accessible to the organist for controlling the same in such manner that the draw-stops may be automatically and pneumatic-ally pushed out or in, collectively or singly, or in predetermined combinations or groups, or one after another as may be required; third, to construct and arrange the various parts of the mechanical and pneumatic draw stop actuating mechanism for operation in such manner that the draw-stop knobs are susceptible of the usual manipulations by the hand of the' organist as soon as said apparatus is not in action; fourth, to provide means for enabling the organist tovcontine the operation of the draw-stop apparatus to certain groups of drawstops'; and fifth, to provide a vvisual signal or telltale for indicating the names of the drawstops that have been brought into position by certain portions of the draw-stop actuating apparatus for being collectively pushed out or in by the subsequent operation of the other portions thereof.

Ourinvention consists of an organ provided with draw-stops, a swell pedal, pneumatic draw-stop actuating mechanism, and a slide operated by the swell pedal and adapted to control said pneumatic mechanism, the construction being such that the opening and closing of the swell causes the slide through the instrumentality of the pneumatic mechanism to let on and shut' off draw-stops one after another, thereby enhancing and perfecting the power, tone and quality of the swell.

.Our invention further consists of a pneumatic draw-stop action comprising a series of draw-stops, pneumatic mechanism for pushing each of said draw-stops out and in, throttle-valves for starting and stopping the pneumatic mechanism to effect the pushing out and in of stops, a slide for controlling the pneumatic mechanism to permit of the simultaneous and successive shifting of all' the stops, and means accessible to the organist for operating the throttle-valves and slide.

Our invention further consists of a pneumatic draw-stop action comprising a. series of draw-stops, pneumatic mechanism for pushing each ot' said draw-stops out and in, a slide for controlling the pneumatic mechanism, draw-plates for confining the action of the slide to certain sets or divisions of draw-stops, and means accessible to the organist for controlling the slide and draw-plates.

Our invention further consists of a pneumatic draw-stop action comprising a series of draw-stops, pneumatic mechanism for pushing each of said draw-stops out and in, combination valves respectively adapted to effect the pushing out of certain stops in predetermined combinations or groups, and means accessible to the organistforoperating said combination valves; and

`Our invention further consists of the iinprovenients in draw-stop actions hereinafter described and claimed.

yIn the drawings CL, is the framework or housing of the desk of au organ. b, are manuals or banks of keys. c, is a bank ot' pedal keys. d, is the swell pedal. d', is a cord or other connection that leads from the swell pedal d to the swell shades or shutters, not shown, and e, f, g, t, i and j, are draw-stops of which any number may be employed. These parts co-operate with the other parts of the organ, which are too well known to require illustration, in the usual manner, that is to say, the respective keys of the different banks of keys permit notes of different pitch to be sounded; the draw-stops when pulled out permit a corresponding stop of pipes to speak when the keys are depressed, and when pushed in prevent said stop of pipes from speaking even when the keys are depressed; and the swell pedal affords means for opening and closing the swell box, whereby the volume of sound is increased or diminished.

Having thus briefly designated so many and such parts of an ordinary pipe organ as are essential to a comprehension of our invention, we will now describe the construction and subsequently the mode of operation of the parts that embody vfeatures ot' the same.

Referring now to the drawings and more particularly to Figs. l, 2, 3 and 4 thereof, k is an air pressure chamber or box to which a supply ot' air under pressure is admitted through a pipe 7c', that communicates with a main reservoir 7a2. rlhis air pressure chamber 7a, is preferably located in rear of the draw-stop knobs and may be disposed in any convenient position, and more than one air pressure chamber or box may be employed.

In the presentinstance this ait` pressure chamber k, is disposed at the right hand side of the organ and directly in rear of the draw-stop knobs, so that the draw-stop rods c,f, g', h', 'i' and j', extend directly backward through the front wall of the same. It may be remarked that the draw-stop rods e', f and g', and certain of their connections are located directly in rear of and are concealed by the draw-stop rods 7L', t', and j', and their corresponding connections and consequently the concealed parts are designated upon the drawings by dotted reference letters. These draw-stop rods e', f', g', 7L', t" and j', are respectively connected with oppositely disposed bellows e2 and c3, f2 and f3, g2 and g3, 7b2 and h3, t2 and t3, and jg and js, located in the air pressure chamber 7s, and supported by means of suitable posts l. The posts Z, are respect ively provided with conduits e4 and egf" and f5, g4 and g5, h4 and h5, t* and tl", and j* and j, (Figs. l, 2, 1l, l2, and 13) that communicate with the bellows e2and c3, f2 and f3, g2 and g, h2 and h3, i2 i3, and 7'2 and/ji, and with a series of valve chambers c and c7,f6 and f7, g and gl, 7L and hl, t and '27, and js and jl'. Fach of these valve chambers is provided with two ports es and ci', f8 and fi), g8 and g, hs and h, t8 and t", and 7'8 and jf. The ports es, f8, gs, ha, t8 and js, are adapted to communicate with the atmosphere and the ports c, fg, g, hg, i9 andjf, are adapted to communicate with the interior of the air pressure chamber 7c.

el" and e, fw and f 11, gw and g, ./tw and h, @'10 and tu and j andj, are valves adapted respectively to permit the conduits e and e5, jA1 and f5, g4 and g5, h4 and h5, fi* and t5 and j and js, to communicate with the atmosphere and with the interior of the air pressure chamber. lf both ot' the conduits that appertain to one pair of bellows, or in other words, to one draw-stop, for example, the conduits 7L* and h5, are in communication with the intel'- ior of the air pressure chamber k, which is their normal position, then the exterior' and interior of the bellows h2 and h3, are subjected to the same pressure, to-wit:-the pressure of the air chamber 7a, and consequently are in equilibrium, so that the draw-stop knob h may be pushed in orpulled out manually and will remain in either position.

The above description, of course, applies to the draw-stops @,f, g, t and j, and their complemental bellows and accessories. llowever, when any one of the bellows c'fz, g2, h2, t2 and jz, is permitted to communicate with the atmosphere by the lifting of its complemental valves cw and @11,f1 and f, qw and g, hw and h, t'lo and t andjw and j ,it collapses and thus causes its corresponding drawstop to be pushed out. Similarly when any one of the bellows e3, f3, g3, 723, 'i3 andj, is permitted to communicate with the atmosphere by the lifting of its complemental valves el and @11,f10 and fu, g1 and g, hw and hu, 'im and i andy'10 and j, it collapses and thus causes its corresponding draw -stop to be IIO pushed in. It being understood that as soon as the valves c10 and 611, f 10 and f11, Q10 and Q11, 7t10 and 7t11, @'10 and @11 and 310 and 311, are permitted to descend the equilibrium of the drawf stop bellows is re-established and the drawstops are free to be be pushed in and pulled out manually in the usual manner. It may be remarked that the movements of the drawstop rods f Q 7@,@" and 3'l are availed of for operating the sliders that control the stops of pipes, not shown. Of course this result may be accomplished by means of many of the well known mechanical or pneumatic devices that are commonly employed for this purpose by organ builders and others skilled in the art. In the present instance this result is accomplished by means of bellows, (not shown,) or pneumaticsas theyare sometimes termed. These pneumatics are controlled by ports fm and their complemental valves m', and the valves m', are actuated by means of spindles m2 and centrally pivoted spring controlled levers 'm3, which latter engage and are actuated by cams/m4, carried by each pair of complemental draw-stop bellows.

@12 and @13, f12 and f13, Q12 and Q13, 7112 and 7113, @12 and @'13 and 312 and 313, are valve bellows mounted upon a suitable board n, and adapted respectively to lift the valves @10 and @11, f10 and f11, Q10 and Q11, 77.10 and 71.11, @'10 and @11 and 310 and 311, and thus cause the draw-stops e, f, Q, 7i, and 3` to be shifted. The valve bellows @12, f12, Q12, 71,12, @'12 and 312 operate to cause the draw-stops to be pushed out and are consequently referred to as the on7 bellows, and the valve bellows e13, 3113, Q13, 7@13, @'13 and V4313, operate to cause the draw-stops to be pushed in and are consequently referred to as the off bellows.

614, 3414, Q14, 7@14, @'14 and 314, Figs. l and 3, are main channels running transversely of the organ and adapted to convey a supply of air to the on bellows @12, 3312, Q12, 7@12, @112 and 312. For this purpose grooves and complemental inlets and outlets @13, f15, Q15, 7113, @15 -and 313, Fig. 3, communicating with the main channels and with the on bellows are cut or otherwise formed in the board fn.

@13, f10, Q10, 7@10, @1G and 313, are main channels adapted to convey asupply of air to the off bellows @13, 3313, Q13, 7t13, @'13 and 313. For this purpose grooves and complemental inlets and outlets @11, 3017, Q17, 7117, @17 and 317, comniunicating with the main channels and with they off bellows, are cut or otherwise formed in the board yn. The channels 614, f14, Q13, 7114, @'14 and 314, are connected with the on bellows @12, '3312, Q12, 71.12, @12 and 312, in such manner that when airis successively admitted to the channels e14, f14, Q14, 7114, @14 and 314, the draw-stops are pushed out one after another in properl order or sequence for the production of a crescendo effect. Of course Ithis order or sequence will depend upon the number and quality of the `stops of the organ and upon the taste of the organ builder the object being to bring on all the stops one after another in such order that the best crescendo effect is attained. In the present instance the drawstops are pushed out in the following order e, f, Q, h, i and 3'. The channels 613, 3313, Q10, 7113, @'13 and3`13, are connected with the off bellows @13, f13, Q13, 7113, @13 and 313 in such manner that when air is successively admitted to the channels @13, f13, Q13, 71,13, @'13 and 313, the drawstops are pushed in one after another in reverse order, and thus produce the reverse of the crescendo, e. a decrescendo eect. In the present instance the draw-stops are pushed in, in the following order-3', h, Q,f and If a supply of air is admitted into all the channels @14, f 14, Q14, 77.14, @14 and 314 at the same time, the bellows @12, f 12, Q12, 7112, @'12 and 312, are all eX- panded with the result that all of the drawstops e, f, Q, 71,0land 3', are pushed out at once. Similarly if a supply of air is admitted into all the channels @13,3313, Q13, 7@13 t13and 313 at the same time, the bellows 613, 34.13, Q13, 7113 @13 and 313, are all expanded with the result that all of the draw-stops @,f, Q, 71 and3` are pushed in at the same time. If a supplyof airis admitted to certain of the channels 614, f14 Q14, 7t14, @'14 and 314, for example, into the channels 614 and 3414, it follows that the stops e and f, will be pushed out either at the same time or successively according as the supply of air is admitted to both of the channels at the same time or rst to one and then to the other of them. Similarly if a supply of air is admitted into certain of the channels e111, 3013, Q10 71.13, @13 and313, for example, into Athe channels Q13, 7113, @13 and 313, it follows that the stops Q, 71, and3', will be pushed in either at the same time or successively according as the supply of air is admitted to all of these channels at the same time or lirst to one and then to the other of them. The upper openv portions of the apertures or ducts 613, f13, Q13, 7t13, @'13, 313, @10, 3310, Q10, 7110, @'10 and 310, that serve to admit air to the main channels, are disposed in a straight line or row, Fig. 6.. The upper open portions of the apertures or ducts 613, 3313, Q13, 7t13, @13 and 313, that serve to admit air to push out stops, vare disposed to one side of the center of said straight line or row `and the upper open portions of the apertures or ducts @10, 3310, Q10, 7110, @'10 and 310, that serve to admit air to push in stops, are disposed at the other side of the center of said straight line or row.

0,'is a slide adapted to close the upper open portions of the apertures or ducts @13, f13, Q13, 7113, @13 and3`13, or the upper open portions of the apertures or ducts @10, f13, Q10, 7t10, 110 and 310 and also to open certain of the former, for example, the inlets 613, f13, Q13, 7113 and @'13, and to close the corresponding inlets @10, 3410, Q10, 7@10 and @10, of the latter. This slide o, affords means for opening or closing all or a portion of the inlet apertures 618, f1.3,.g13, @'13 and 313 one after another, thus causing the drawastops to be pushed out one after `another and also for opening or closing all or a portion of the inlet apertures @10, f 10, Q10, @'10 and 310, one after IOO IIO

another, thus causing t-he draw-stops to be pushed in one after another. Moreover this slide o, altords means for uncovering all or a portion ofthe inlet apertures c18,f12, Q18, @'18 and Q18 at the same time, thus causing all or a group ot the draw-stops to be pushed out at the same time and also for uncovering all or a portion of the inlet apertures @19, f1, Q19, @'19 andj11 at the same time, thus causing all or a group of the draw-stops to be pushed in at the same time. Certain of the apertures @13, fis7 gisa his ,Lis7 jle, 619,]@19 gm, ]1:1,19&Ddj197 we curved and certain of them are straight, (Figs. 3, 4, 6 and 7) and the lower portions of them are disposed in three parallel lines or rows; in the present instance the lower portions ot' the apertures e151, h18, e111 and h1 are disposed in one straight line or row, the lower portions of the apertures f18, @'13, fw and 2'111, are disposed in a second straight line or row, and the lower portions of the apertures Q18, '18, Q19 and Q12, are disposed in a third straight line or row.

29,19 andp2, are three perforated draw-plates adapted respectively to open and close the apertures @18, k12, 619 and k12, f12, @'18, f 11 and @'19, and Q18, 7111, Q1D and 3'11, in order to prevent the admission of air to the corresponding main channels even when the slide o, is in position for opening them. These draw-

plates

19,19 and p2, thus attord means for excluding certain groups of draw-stops. In the present instance the groups comprising respectively the draw-stops e, h,f and 1l and Q and j from the action of the slide o. It may be remarked that in most instances the stops controlled by each ot the draw-plates would appertain to one of the organs into which the complete instrument is conventionally divided, so that the operation of the slide o, could be confined to one or more of the divisions ot the instrument, for example, to the swell organ. The lower open extremities of the apertures e111, fis, gis his2 18, jle ein, floa gio 7,/19119 and ju), are adapted to communicate with the interior of an auxiliary air pressure chamber Q,to which a supply of air is admitted through a pipe q', from the main air reservoir k2.

r, isa throttle valve for controlling the admission of air to the apertures c18, f18, Q18, 71111, 12 and l712 that tend to operate to effect the pushing out of stops.

fr', is a throttle-valve for controlling the admission ot' air to the apertures 619, f 12, Q12, h1", @'19 and 719 that tend to operate to etect the pushing in of stops.

The slide o, throttle valves r and r', and draw-plates 19,29 and p2, attord means whereby all or a portion of the draw-stops @,f, Q, h, t' and j, may be pushed out or in successively orcollectvel y or in predetermined groups. ln practice it is frequently necessary or desirable to push out draw-stops in groups other than those above referred to and commonly designated combinations by organists, organ builders and others. This result is accomplished by the employment of an ancillary air pressure chamber s, supplied with compressed air from the main air reservoir k2, and provided with complemental valves, here inaf ter designated combination valves, and of which three s', s2 and s2 are shown.

e211 and f20 are holes bored in the bottom wall of the channels e11 and f11 and Q21, h21, 21 and t7'21, are holes bored in the bottom walls of the channels Q16, h11,f11andj11". These holes e211, f20, Q21, 7t21, Q21 andj21, are all adapted to be broughtinto communication with the interior of the ancillary air pressure chamber, by the opening of the valve s', so that when the valve s', is opened the stops e and f, are pushed out and the stops Q, 7L, fi and j, are pushed in.

e22, f22, Q22, 71,22 and Q22, are holes bored in the bottom walls of the channels c11,j`11, Q11, h and 711 and @'23 is a hole bored in the bottoni wall of the channel 111. These holes e212, f22, Q22, 7t22, Q22 and @'23, are all adapted to be brought into communication with the interior of the ancillary air pressure chamber s, by the opening of the valve s2, so that when the valve s2, is opened the stops e, f, Q, h and 7' are all pushed out and the stop 7l, is pushed in.

f21, h21 and Q21, are holes bored in the bottom walls of the channels f, 71.11 and j11, and c25, Q25 and 25, are holes bored in the bottom walls of the channels e111, Q16 and 116. These holes f21, 7L21, Q21, c25, Q25 and @'25, are all adapted to be brought into communication with the interior of the ancillary air pressure chamber s, so that when the valve s3, is opened the draw-stops f, 7L and j, are pushed out and the draw-stops e, Q, and 7l are pushed in.

WVe have described means for pushing out three combinations of stops, to-wit:-e and f; @,f, Q, h and j; andf, 7L and j. However, it must be borne in mind that any number of dierent combinations may be had by employing additional valves and their accessories similar to the valves s', s2and s3 and their accessories. The Valves s', s2 and s3, serve to push out draw-stops as has been already eX plained' and these draw-stops may be subse-` quently pushed in either by hand in the usual manner or by means of the throttle valve 'r' and its accessories. The slide o, is preferably composed of celluloid or other similar material, and works between two sheets of leather o and o2, Fig. 7, which serve to prevent undue leakage. The draw-plates p, p and p", also work between sheets of leather p2 and p, Fig. 7, or analogous material inorder to avoid undue leakage.

The slide, draw-plates, throttle-valves and combination valves may be operated through the instrumentality of any suitable mechanism under the control of the organist. In the present instance the throttle valves lr and lr', are controlled b v the sidewise motion of the foot of the organist as the same rests upon the swell pedal d. This result is accomplished by the employment of lugs t and t', pivotally attached to the swell pedal d, in range of the toe of the organist, and connected together by` means of a spiral spring t2. The movement of ICO the lug t, toward the left in Fig. 2, imparts a rocking motion to the arm '63 of the roller t4, and the rocking motion of the roller t4, causes the arm t5 thereof to open the throttle valve fr. Similarly the motion of the lug t toward the right in said figure, acting through the instrumentality of the roller t6 and its complemental arms, causes the throttle valve r', to be opened. rPhe slide 0, is connected with the swell pedal el, through the instrumentality of suitable tracker-work o3, and is shifted toward the right in Fig. when the toe of the swell pedal is pushed forward in order to open the swell' shutters or shades, thereby opening the channels 614, fm, g, h, t and 714, and thus pushing out the draw-stops one after another. When the toe of the swell pedal is released in order to close the swell shades or shutters, the slide o, is shifted toward the left in Fig. l, thus opening the channels @16,f16, gw, hu", 16 and jle and permitting the draw-stops to be pushed in one after another and in reverse order.

u, is a spring controlled indicator or telltale that has the names of the stops printed or painted upon it and disposed in the same order in which the draw-stops are pushed out or in by the normal operation of the slide o. This telltale or indicator' is located behind a suitable window in sight of the organist and is connected and caused to move with the slide o, through the intervention of a suitable flexible connection u', in such man nei-that the names of the stops that correspond with the apertures that are uncovered by the slide are visible through the window for purposes to be presently described. The draw-plates jp, p and p2, are respectively controlled by setsof complement-al push buttons c and c', which operate through the instrumentality of suitable tracker work c2, to effect the required movements of the draw-plates in the direction of their lengths. The combination valves s', s2 and s3, are opened and closed through the instrumentality of combination pedals w, w and 102 accessible to the organist and their complemental tracker work w3.

The mode of operation of the hereinabove described draw-stop action is as follows The organist may play upon the banks of manuals b and pedal keys c and may shift the drawstops e,f, g, 7L, t' andj in and out and operate the swell pedal d, in the usual manner. However, the organist may enhance, perfect and completelthe tone, power and quality of the swell pedal by turning his toe toward theleft in Fig. 2, thus effecting the opening of the throttle-valve r, and then pushing his toe forward thus effecting the movement of the slide o toward the right in Fig. l. The result of these movements is two-fold, the shutter or shade of the swell-box is opened and the draw-stops are pushed out one after another in proper order for the production of a grand crescendo. It being understood that the draw-plates p, p and p2, are in on position. Si milarly the organist may turn his toe toward the right in Fig. 2,

thus effecting the opening of the throttlevalve r', and then release the pedal d, thus effecting the movement of the slide 0, toward the left in Fig. 2; the result of these movements is also two fold, the shutter or shade of the swell-box is closed and the draw-stops are pushed in one after another in reverse order for the production of a diminuendo or decrescendo effect. The organist may push all the draw-stopsout at the same timeby first shifting the slide o, toward the right in Fig. l, by pushing his toe forward and then turning his foot toward the left in Fig. 2, in order to open the valve fr. Similarly the organ-v ist may push all the draw-stops in at the same time by first shifting the slide 0, toward the left in Fig. l, by releasing the pedal d, and then opening the valve r by turning his toe toward the right in Fig. 2. In some instances it is necessary or desirable to confine the operation of the slide 0, to certainv groups of stops, for example, to the stops of the great, pedal or swell organs. The organist may accomplish this result by pressing upon one or more of the buttons 12 or fu', which serve to shift the corresponding draw-plate or plates into position for excluding or admitting a supply of compressed air to the main channels which appertain to the required group of stops, for example, the stops of the great, pedal and swell organs.

The organist in playing is frequently required to pull out stops in certain groups which are often availed of in musical compositions and are commonly designated combinations and to push in all the other stops. This result is accomplished by means of the combination pedals w, w and 102.

It may be remarked that as soon as the supply of compressed air is cut oi from the valve bellows that appertains to any of the respective draw-stops, the latter will remain in the positions that they occupied when the supply of air was cut off, and are perfectly free to be pushed in or drawn out by hand,and the supply of air is normally cut off from the valve bellows, because the valves r and r and s', s2 and s3, are normally closed and are always returned to the closed position either by gravity or by the intiuence of springs as soon as the lugs t and t', and pedals w, w and wz, are released by the organist. Obviously this result is very important and of great practical value, because it enables the organistto push outdraw-stopspneumatically and to then operate them manually without causingthem first to be pneumatically returned to their initial positions. Before the organist turns his foot either to the left or to the right in order to actuate the valves rand r', it is important that he should know the position of the slide o, and consequently the names of the draw-stops that would be actuated by such movement of' the foot. rlhisinformation may be had at a glance by reference to the indicator or telltale u, and if the slide o, is thus found to bein incorrect posi- IIO tion it may be properly adjusted by shifting the swell pedal (l, as maybe required, before the foot is turned sidewise.

It will be obvious to those skilled in the art to which our invention appertains that some of our improvements may be employed without the others and that modications ma be made in details of construction and in the disposition of parts without departing from the spirit of the invention, hence we do not limit ourselves to the precise arrangement hereinabove set forth and illustrated in the accompanying drawings; but
