duction of a novel, useful, and feasible arrangement and control of the various means employed.

In the drawing forming a part hereof Figure 1 is a representation in diagram of the mechanisms employed together with the circuits and the relation of the same.

Fig. 2 is a section on the line 2-2 of Fig. j

Fig. 3 is an end view of the switohbar A and a front view of carrier A Figs. 2 and 3 show the relation of the contact h of carrier A and its adjacent projecting contact 7 of switchbar A t The re-' lation of the other carrier contacts to their respectively adjacent projecting switchbar 1 contacts is similar to that shown in Figs. 2-

and 3. i

Fig. 4 is a side view of a key and its associated contacts. v I Fig. 5 is a view in perspectiveof a por tion of a carrier, as A, viewed from underneath and from thecontact spring side of'the carrier, or as seen from the top side of the sponding to 0, 01.12, c, a#, b, and 0 of the f drawing and from beneath. Thus viewed the order of the contacts is the reverse oi that shown in Fig. 1, so that whereas in Fig. 1 the order from left to right is g, k, in Fig. 5 it is k; g, from left to right. In Fig. 5 the number of contact springs requisite to the octave,-as from a to c inclusive, are shown,

g, g g, g", g, and h respectively correscale.

In the drawing, D represents a battery ee A41 B47 A48, d B48, ach rePresents a note sounding device of the usual electro-magneticconstruction for the control of the speaking of anorgan pipe associated therewith, said pipe not being shown: in the drawing. Each of the note sounding devices A, A", A, is designed to controlthe speakin of a-diflerent organ pipe of a reg- 'ister, w ile the note sounding devices B, Bf', B, are each designed to control the speaking of a difierent organ pipe of another three note sounding devices controlling the organ pipes of a register, while B, B, B, represent the corresponding note sounding devices controlling the organ pipes of another register. A, A, and A, as representing notesounding devices controlling organ pipes serially an octave apart. And so with regard to the note sounding devices 13, B and B.

A tO-A inclusive and B to B inclu- It is desirable to consider register. A, A, A may represent any si-ve represent carriers of insulating material I a each independently movable longitudinally and each designed to carry contacts represented by g, h, and 2'.

A, A, A, and B, B, 13, represent switchbars of conducting material. Switchbars A A, and A, are placed adjacent to and at right angles to the contact carriers A to A inclusive. and B are placed adjacent to and at right angles to carriers B to B inclusive. Switchbar A is placed adjacent to the 9 contacts of carriers A to A inclusive.

Switchbar A is placed adjacent to the h contacts of carriers A to A inclusive.

Switch-bar A is placed adjacent to the 2' contacts of carriers A to A inclusive. Switch-bar B is placed adjacent to the 9 contacts of carriers B to B'- inclusive. Switch-bar B is placed adjacent'to the k contacts of carriers- B to 18 inclusive. Switch-bar B is placed adjacent to the 2' contacts of carriers B to B inclusive.

Each switch-bar is movable in relation to the adjacent contacts. The relation of each switch-bar to its adjacent contacts is such Switchbars B B that when a contact and itsadjacent switchbar are in the unoperated position they are out of engagement and can only be brought into engagement upon their being conjointly in the operated position. It is the function of the several carriers to bring their contacts into the range of movement of the switch-bars adjacent to those contacts.

For the purpose of facilitating the drawing of the claims and for the sake of simplitying the description of thisinvention eacli switch-bar and its adj acentlcontacts are considered as constituting a multiple circuit closer since by these instrumentalities any one of several circuits may be closed by the movement of the switch-bar and the proper carrier to their operative positions, each multiple circuit closer therefore including independently movable contacts and a switch riers B bar, each contact and the adjacent switchbar constituting a complete circuit closer within the meaning of certain of the appended claims. Thus the g contacts of carriers A to A inclusive and the adjacent switchbar A constitute multiple circuit closer No. 1: the h contacts c. carriers A to A inelusive and the adjacent switch-bar A con stitute multiple circuit closer No. 2: the i contacts of carriers A to A inclusive and the adjacent switch-bar A constitute multiple circuit closer No. 3: the 9 contacts of carriers-B to B inclusive and the adjacent switch-bar B constitute multiple circuit closer No. 4: the h contacts of carriers B to B inclusive and the adjacent swltch-bar B constitute multiple circuit closer No. 5:;

and the i contacts of carriers B toB inclusive and the adjacent switch-bar B constitute multiple circuit closer No. 6.

In the drawing each switch-bar is represented as carried by an insulating support and as having projections a to 7" each to engage with an adjacent contact. The projections a, b, c, d, e, f, of s'witchbar A are de signed to engage respectively with the 9 con tact springs of carriers A, A", A, A, A A; the projections a, b, 0, d, e, f, of,

switchbar A are designed to engage respectively with the h contact springs of carriers A A, A, A, A", A; the projections (1, b, c, d, e, f, of switchbar A are designed to engage respectively with the i con.

switch-bar A of multiple circuit closer No.

1 is moved to operativeposition. Similarly the operation of keys' A A B B B closes circuits-through electro-magnets A, A", 13 B B and moves the switch-bars A, A B B, B of multiple circuit closers 2, 3, at, 5, 6, to operative position.

If stop A alone be drawn to the out position a circuit is closed through the elcctro-magnet A and carrier A is -moved so as to bring its contacts 9, h, i, re-

spectively into the range of movement of switch-bars A, A, and A. If, now,

while stop A is drawn switch-bar A be.

closed through the note sounding device- B by reason of the engagement of the contact g of the operated carrier A by the operated switch-bar A; if switch-bar A be moved by depressing key A a circuit closed through the note sounding device 3 by reason of the engagement of the contact it of the operated carrier A by the operated switch-bar A; if switch-bar A be moved by depressing key A a circuit is closed through thenote sounding device B by reason of the engagement of the con V engagement of the contact 9. of the operated carrier A by the operated switch-bar A; if switch A be moved by depressing key A? a circuit is closed through the note sounding device A by reason of the engagement of the contact h of the operated carrier A by the operated switch-bar A.

If stop A alone be drawn to the out position a circuit is closed through the electro-magnet A and carrier A is moved so as to bring its contacts 9, It, 2', into the range of movement of switch-bars A, A, and A. If,-now, While stop A is drawn switch-bar A be moved by depressing key A a circuit is closed through the note sounding device B by reason of the engagement of the contact 9 of the operated carrier A by the operated switch-bar A; if switch A be moved by depressing key A a circuit is closed through the note sounding device B by reason of the engagement of the contact 71, of the operated carrier A by the operated switch-bar A.

If the stops and keys be operated 001-. lectively in any combination the above described results are in no way changed.

What has above been described with reference to the operation of the A stops and A keys is equally applicable to the operation of the B stops and B keys in which case the B carriers and B switchbars are involved instead of the A carriers and A switches.

The circuits involved can be readily traced by one skilled in the art.

If keys A A A", be considered as be-' longing to one keyboard and B B B as belonging to another keyboard it follows that a given note sounding device can be operated by a key in either keyboard either of the same pitch, or of the octave below, or of the octave above, singly or simulta neously.

It is obvious that further duplications of keyboards requires but a like duplication of the arrangement shown and described.

It is obvious that equivalent electromagnetic apparatus, as solenoids, may be substituted for the electromagnets.
