T 0 all whom it may concern:

Be it known that I, WILLIAM KAIsLING, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Combined Electromagnetically and Manually Cperable Organ-Stops, of which the following is a speciiication.

My invention relates to stop key devices for organs, and has to do more particularly with keys which may either be manually or electromagnetically controlled, an object of my invention being to provide an improved arrangement of parts whereby an effective and eilicient control is secured. Certain teatures of my invention reside in the combined structure includingkey and electromagnet.

For an understanding of my invention reference is to be had to the accompanying drawing in which like parts are indicated by like reference characters, and in which v Figure 1 is a side view of the preferred embodiment of my invention;

Fig. 10 is a top View of Fig 9;

Fig. 11 is a sectional View of Fig. 9, along the line 11, 11 and in the direction of the arrows indicated thereat; and

Fig. 12 is asectional view along the line I 12, 12 of Fig. 10.

Referring now more particularly vto the preferred embodiment or' my invention as shown in Figs.V 1 to 6 inclusive. A stop key 1 is provided pivotally supported by a shaft 2 resting in grooves 3 of bracket t. A snap spring 5 is provided slotted at its upper end and resting in a groove in screw '7, which screw is threaded into the tace board 8 of the organ frame A and may be adjusted. rIhe lower end of the spring 5 rests in a groove 9 in key l, said groove being so positioned that when the key in the normal position shown by the full lines in F ig.` 1 the bearing portion of the spring 5 is to the right or" a linel drawn from the pivot 2 to the slot in the screw and thus tends to hold the key in its said position. II" the key is pressed downwardly atits forward end as soon as the slot 9 has advanced to a position on the opposite side of the previously referred to line between pivot 2 and the slot in screw 7, said spring 5 acts to quickly move the key to its alternate or dotted position. Likewise when the key is moved upwardly, spring 5 tends to snap it into its normal position. In this way the key is moved into its positions by quick movement and then held thereat.

As above referred to, the key may be either manually or electromagnetically operated and for the latter purpose I provide an electromagnetic structure B comprising electromagnets 10, 11, having their cores 12, 13 fastened to a bracket 11- pre'terably of a material capable of magnetization. An armature 15 is provided and is pivoted by a pin 16 passing through a slotted end 17 of a pole piece 18, said pole piece being shown by dotted lines in Fig. 1 and extending between the spools 10 and 11 and secured to the bracket let by screws 19. This pole piece 18 is of magnetizable material so that either electromagnet spool when independently energized attracts the armature 15 thereto.

A member 20 connects armature 15 to the stop key, being fastened to the armature by screws 21 and having a slot 22 at its free end which slot coperates with a key eX- tension 23 supporting abufer 24; preferably of soft rubber tubing.

The electromagnetic structure B also controls the set of contacts C comprising an intermediate or common contact 25 and coperating contacts 26, 27. A coperating arm 28 is carried by armature 15. The arm 28 has its tree extremity slotted thus forming contact ends ot ngers 29 for cooperation with the stationary or passive contacts C)5, 26 and 2T. The contact ends of fingers 29 are bent back at right angles to the arm 28 to bring them into position to wipe over said passive contacts 25, 26 and 2T. When arm 28 is in the position shown in 1lull line) in Fig. 3, contact 26 is electrically connected to common contact 25 through the wiper iingers 29 of the arm 28, and when the arm 28 is in 'the position shown (dotted) in Fig. 3, contact 27 is electrically connected to common contact 25 through the wiper fingers 29 A various purposes and as my invention Vis of the'arm 28. The stationary contacts 25,

26, 27 are mounted upon an extension 30 preferably Vfastened to the pole piece .18 hy connected to the common contact 25l screws V3l. As shown in Fig; 3, contacts 2G and 27 are insulated from the extensionO, said contacts having prongs 32 bent under the insulating strip 33 to hold the contacts firmly thereto.V kThe common contact 25 is preferably in electrical contact With the eX- tension being secured thereto byscrevvs 34.V rIhus the frame ofthe electromagnet is' Assuming. the parts Yare in theVV position Vshown by the VVfull lines vof the different iigures, should the key lY he depressed,a s'V soon'as slot 9 on the key `passes its center,

that is a point VVon the line between jpiv'ot- 2 f and the slot'in screw v 7 ke l is sna ed downiva `dly and thebu'iiier 2a carriedhy the keyengages the'upper'side of the slot 22 of arm 2O whereby the arm is moved upwardly into its dotted position thereby carrying rinature 'i5 'and contact arm 28 into their dotted position and thus connecting contacts 25 and 27.

have referred to theinethod of moving the parts from their full to their .dotted V positions hy a manualV actuation of the stop key but these parts may VVloe actuated by an' energization ci one ofthe electromagnets. Therefore, if the parts are to he moved from their ullline to their dotted line positions, an energization of coil l1 of the electromagnet draws'thearmature 15 to its dotted poi sition whereby contactarm 28 carried thereby crosses or connects contacts 25, 27. The, consequent movement of arm'20 causes the lower edge o'tits slot/22 to engage 'the keyv .their normal or full line position? either' manualiy or hy the .electromagnet coil 10.

J Referring now to the modiiication .shown 'y' kin Figs. Tte l2, inclusive, Valthoughl have Vshown Vonly the electromagnetic structureB1 and contacts ycontrolled thereby, it isto 'bef understood 'that this device may be used in place of the device Botthepreferred form er" my invention aswillbe apparent from a comparison of the drawings.V The principal l difference in'theA constructionv of electromag-V netic structure B and B1 lies in the pole Ypiece VWhich connects the armature and Vbracket, the pole piece in the modiiied form consistingoic the U-shapedelement compris-V ing .pole extensions V181 and 182 through theV free ends oic which the pivot ypin161 extends.

[This pin 161 lies in a slot transverselycut into-the armature 151, saidlpin being 'clamped by a plate 4:0, (Fig. l0),- vvhich is positioned hetween the arm 201, 281 andthe armature. Thus the pin is rigidly secured to the Varmaturelnit pivotal in the eXtensions 181, j182.V Theiingers 291 of .arm 281 engagecontacts 251,281 and 271 Which are secured toA an insulating plate 331 in a manner similarto that shown in TEig. 6. 1nthe presentform of my invention the contacts and insulating plate are secureddirectly to the pole extension 181. Y. L f The operation of the electromagnet ofthe modified forni or" my invention is the same asY that et they preferred form, and it is thought this operation Will loe readily understood in view oi the previous description.

Although the electromagnets of my invention are adapted i'or coperation with theV stop key, it is/to heunderstoodthat I contemplate employing them mother Ways as it is evident the electromagnet may be used' in other Ways than Vthat shown. V'For' instance, it may heemployed hy itself for con-v trollingw its contacts and; thus he 'jused Yas Aa relay. ltrivill also; he apparent that changes andmodications of my'invention may oc- .'cur to othersfthis-depending upon the use to which' thedevice is put.y Therefore, l do not'desireto'he limited to theeXa-ct st'ruc- Y tures. as Ashown and'descrihe'ch Vlout aim to cover all that which'comes VWithin the Vspiritv and'scope of theV appendedY claims.' l
