ORGAN.

To all whom it may concern:

Be it known that I, EDWIN Wnrenr, a subject of the King of Great Britain, residing at 654 Holloway road, London, England, have invented new and useful improvements in Organs, of which the following is a specification.

My invention relates to organs of the kind wherein the bellows are operated by the feet of the player, the object of my invention being to provide in conjunction with the treadles means whereby a performer can play a pedal part to the music with both feet while at the same time the feet are engaged in blowing the bellows of the instrument.

According to my invention I combine with the treadles or footboards of the instrument a series of key levers or abutments which are connected by suitable mechanism with the reeds or pipes of the manual or with an independent set of reeds or pipes, the movement of the said levers or abutments being operated by pushing the feet against them.

In the accompanying drawings :Figure 1 is a sectional side view showing so much of an American organ as is necessary to illustrate the application of my invention. Fig. 2 is a sectional side view showing the mechanism in connection with the bellows treadle drawn to a larger scale than Fig. Figs. 3 and 4 are respectively a plan view and an underside view of one of the treadles, showing the arrangement of the key-levers thereon and some of their connections. Fig. 5 is a view of a detail. Fig. 6 is a plan view illustrating a modification of my invention wherein the treadle levers are arranged in conjunction with a series of reeds independent of the manual, and Fig. 7 is a plan view of a portion of Fig. 6 drawn to a larger scale and embodying certain details not shown in the latter figure. Figs. 8, 9 and 10 are sections on the lines 88, 99 and 1010 respectively of Fig. 7 Fig. 11 is a view of certain parts shown in Fig. 10 but in a diiTerent position.

a indicates the keys of the instrument, I) the reservoir bellows, c the eXhausters and (Z a treadle for operating the said exhausters, these parts being arranged in the usual manner. e, e", e e e 6 are a series of spring key-levers which are mounted on the said treadle by means of pivot pins f which extend through the treadle to the undersides thereof, the said levers being arranged in Specification of Letters Patent.

such positions that the movement of the foot forward or backward or of the toe or heel in a lateral direction to either side will cause the movement of one of the said key-levers such movement being limited by stop pins 0*, e The pivotf of each of the key-levers has attached to it beneath the treadle an arm g, the free end of which is connected to one end of a double armed lever the other end of which extends down into a position acent to the hinge 7b of the treadle. The conned tion between some of the arms 9 and the levers g is effected by links 1 and also by a pin and slot g as shown clearly in Fig. l.

Upon the base of the casing a is pivoted a series of double armed levers & with which the several double armed levers respectively cooperate, each lever 9 being at its end nearest the hinged joint of the treadle proed with a lug or extension j cooperating with 2. lug or extension on a lever i so that when the lever g is moved laterally the lever i will also be swung laterally upon its pivot. It is to be understood that the size and positions of the lugs 3, 7c are such that they will always be in contact notwithstanding the movement of the treadles. It is to be understood that the treatlle should be in its depressed position, when the valves are operated. The lever t at its rear end bears against one arm of a bell-crank lever Z as shown clearly in Fig. 5, the other arm oi which lever has connected to it one end of a sticker m, the upper end of which is jointed to one end of a lever 11 which at its other end is arranged in conjunction with a pallet or valve of a reed of the manual as will be clearly understood by reference to Fig. 1. "ffith this arrangement it will be unierstood that the movement of either of the keylevers e, e etc. can be communicated to the corresponding pallet.

Instead of the parts i, 7:, Z, m, n for actuat ing the pall ts i may employ pneumatic connections; the movements of the extensions 3', y' cooperating with the valves governing the admission of air to tubes or channels connected with corresponding pallet motors in a well known manner.

In order to allow oi reai 'ily moving the foot in contact with either of the key-levers it is necessary to provide for momentarily locking the treacles against upward movement on their hinges and this I advantageously accomplish in the following manner: To the underside of the foot-board d I rigidly attach a pneumatic chamber 0 preferably of bellows form, as shown in Figs. 1 and 2, the bottom board 0 of which is held in a practically fixed position so that during the oscillation of the treai le the pneumatic chamber will be alternately filled and emptied. In the drawing I have represented the said. bottom board 0 as provided with extension 0 which passes between rollers 0 0 carried in the framing and which allow of any slight movements of the extension due to the fact that the hinged joint of the pneumatic chamber does not coincide with the hinge of the treai le. The upper board or part of the air chamber 0 is fitted with two valves 19, p, the former of which is an oralnary i'lap valve which at all times allows the air in the chamber to escape when the footboard is pushed downward. The other valve p is of the hinged or pallet variety and is closed in the ordinary way by a spring 29 This valve 1) has arranged in connection with it a short rod 21 which passes through the treaule d and projects slightly above the same.

Upon the treadle d is a loot-plate g capable of a slight rising and falling motion relatively to the tread-lo; The loot-plate 1 may be hinged to the l'ootboard at any convenient part for instance as shown at g or it may lie freely in the recess provided for it, and be kept in position laterally by two or more loosely fitted dowel pins. This loot-plate, in the drawing, is represented as being shaped to the sole of the foot but it may be 01' any other convenient shape and may occupy the whole of the available space between the key levers e, 60, etc. The said footplate g is acted upon by a sprin T, the power oi' which is so regulated that during the movement of the treadles by the performer the said "loot-plate Q will be pressed downwards so as to hold the valve p open and allow free ingress and egress of air into and from the pneumatic chamber 0 whereby the latter will not offer any impediment to the tree operation of the footboard.

When the performer desires to operate one or other of the keylevers he first raises his foot sufficiently to take the pressure off the foot-plate g so that the spring g w ill raise tn said plate and allow the valve 10 to close under the action of its spring p. The result of thus closing the valve 33 will be to prevent the air from entering the pneumatic chamber 0 whereby it will be obvious that the top board of the chamber and also the treadle d will remain stationary until the operator again presses upon the plate g to open the lve p The groups of key-levers e, 6 disc. and the plates gon the iootboards may be inclined or splayed to suit the natural outward inclination of the feet. I g

It is to be understood that the invention isnot limited to any particular arrangement of the Key-levers, as any arrangement of such levers upon the treadles to be operated by the feet may be employed and it is also to be understood, that the number 01'' such key levers may be increased or decreased as desired. In the arrangement before described I have shown the treadle as provided with six levers so that both treadles would have between them twelve levers corresponding with the twelve semitones oi' the chromatic cale but when the invention is employed in conjunction with an independent set oi reeds l advantageously make use of the arrangement shown in Figs. '7 to 11. In this arrangement l have shown three sets of reeds r, s, t (Fig. 8) oi the scales known as 16 feet, 8 feet and 4 feet respectively, the chambers containing the several sets oi reeds being adapted to be closed by rnutes r 8 and t respectively. The corresponding reeds o'l' ie three sets are controlled by a single valve a which is operated by a sticker m controlled by one of the treadle levers or pneumatically in the manner hereinbe'lore described, whereby when either of the said trcadle levers e, c do. is operated, the corresponding valve a ill be opened to sound the particular reed of the three sets of reeds the mute of which is raised. The control of these mutes is advantageously effected pneumatically, although they may be othcru ise operated. in

the drawing 1 have represented three pneumatic motors r 3 i which are designed to respectively control the mutes through the medium of levers W, 8 i each ol' uliiclris at one end directly acted upon by its motor and at the other endcairies a stick-r rod which acts against a crank-aim on the mute in such a manner that when the corresponding motor is operated the mute w ill be raise l to allow the corresponding set of reeds to sound when the valves or pallets u are opened.

In conjunction with the several motors are passages r, s, t in the top of the wind-chest o, the said passages being respectively controlled by valves W, 8 t so as to put the motors in communication with the atmosphere. Normally the motors T 3 t are in communication with the wind-chest by spring valves r s and t respectively arranged on the un dersides of the said motors the said valve being held in the open position against the pressure of their springs by extensions W1 on the undersides of the valves 1- 3 t abuttin against extensions c on the said valves r, s and t. The motors W, s and t are normally kept closed by the springs of the mutes acting through the levers T 3 t The control of the several valves W, s and t by the performer, is ef ected through the medium of levers w x which are placed in such a position relatively with the keyboard that they can be depressed by fingers or tile wrists of the performer either independently or simultaneously. The levers w and :v are mounted respectively upon spindles w x which also carry arms w 0: which bear upon a T-piece y. This F-piece y is suspended from the casing by means of a spring 3 (Figs. 9 and 10), the spring normally holding the said T-piece in the position indicated by the dotted lines in Fig. 10. The vertical leg 3/ of the T-piece cooperates with a pivoted spring a m g which carries the valve 3 Fig. 9, and it has also extending: in a forked portion through it, a rod p which operates two spring levers w, 9: which carry the valves a and t" respectively. The rod 'f slides through holes in the levers w m and is pro vided with buttons g so that the said levers can be operated independently. ith this arrangement when the performer wishes to raise, say, the mute 8 he presses down the levers :0, w simultaneously, so that the "l"- picce p, which is acted upon at the two ends by the levers "L0 5& will be moved down vertically to the position shown in Figs. Q and l0 to lift the valve 8 tne result of which will be that the suction within the wind chest '0 will cause the motor 8 to expand by the pres- 25.33 of the atmosphere and through the mea of the lever s and the connected er rod raise the said mute sso that any i the reeds therein will sound when the reiective pallets or valves it, a, are operated y the treadle key-levers. If, on the other hand, the performer desires to raise the mute 7' he depresses the lever 93 only, so that the "i -piece, instead of hing moved down vertically is rocked to one side, as shown in Fig. 11, this movement having the eiiect of opening the valve 7- To lift the mute t the lever to is depressed whereby the l nece is rocked in the opposite direction to that shown in ll.

For the purpose of retaining open any mute which has been raised 1 provide a supporting device in connection with the crank arms or the several mounts. This supporting device, as shown, is in the form of an oscillating plate z which is controlled by a rod e having one end adjacent to the keyboard and at the other end connected to a bell crank lever which in its turn is connected by a link 2 to the plate. The connection between the rod 2 and the plate is slotted, as shown at 2*, Fig. 9, so as to allow of the oscilla -t on of the plate without moving the rod 2 Zi lion the rod 3 is pushed back the plate 2 is thrown out of contact with all the cranked arms of the mutes. If, now, any one of the three sets or" reeds is to he uses, the rod 2 is pulled outward so that the plate 2 will lie against the cranked arms with the result that when either or" the said cranked arms is lifted it ill oscillate the plate z until the cranked arm rises above it, the said plate then dropping back beneath the said cranked arm and retaining it raised, as shown in Fig. 9. ll, during the operation of playing, the performer for the purpose of extending the eilective compass of the pedal keys desires to change from one set of reeds to the other he operates the rods 9: or w or both together as the case may be, to raise the mute of the particular set of reeds desired, which operation has the effect of moving the plate 2 so that the mute previously supported thereon will drop while the mute which is being raised will be retained. by the said plate, it being understood that the slot allows of this movement of the mute, the natural tendency of the said plate being to always fall toward the cranked arms. When the plate 2 is pulled back out of contact with the cranked arms of the mute, it will be understood that either of the mutes may be momentarily raised and then lowered by the operator to allow of the sounding of a reed in any of the three sets, or the three mutes may be raised simultaneously, and held open by an ordinary draw-stop action.
