JOHN T. AUSTIN, OF HARTFORD, CONNECTICUT, AssIGNoR To AUSTIN ORGAN COMPANY, OT HARTFORD, CONNECTICUT, A CORPORATION or MAINE.

GRGAN STOP-ACTON.

To all 'whom it may Concern.:

Be it known that I, JOHN T. AUSTIN, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Organ Stop-Actions, of which the following 1s a specification.

This invention relates to organ-stop-actions, one of the primary objects of the 1nvention being the provision of simple and effective means operative at the will of the organist, for simultaneously returning to their normal or off positions several stopoperating members which may be on, thus facilitating the work of the player.

Another feature of the invention is the provision of means by which several of said members can be concurrently moved from i off 77 C on.

These features can be employed separately or together but in that one Of the several forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification, these two offices are secured by the same part. As will be inferrcd, however, this is not always necessary. I do not restrict myself to the particular showing made by said drawings and the. accompanying description thereof; I may depart therefrom in several ways Within the scope of the invention defined by the claims following said description. In the organization shown there is provided a device which through the intervention of suitable means draws off any stops of a and which also draws on all thc stops of said group.

Referring to said drawings: Figure l is a perspective view of a stop-action involving my invention. Fig. 2 is a detail view in side elevation of a part of circuit-controlling means hereinafter more particularly described. Fig. 3 is a detail view in sectional elevation, of a stop-operating member, certain of its connections and a bar associated with said stop-Operating member and certain of its mates. Fig. 4c is a perspective view of said bar and its carrier and the supporting shaft for the latter.

Patented Mar. 16, 1915.

serial No. 798,322.

Fig. 5 is a sectional elevation of-a roller in its shifted relation, a portion of a trace and an actuator on said trace.

Like characters refer to like parts throughout the several figures.

An organ usually comprises several stopoperating members and these can take different forrns; for instance they might be operated directly by hand, by foot or otherwise. In the construction shown, however, the stop-operating members are shown as being manually-operable; it will be clear that the invention, however, is not restricted in this respect. In connection with stopoperating members of whatever type they may be, I provide means for simultaneously returning to normal or initial positions those stop operating members that may have been moved to their off positions, and this means may be of any desirable nature. The means in question is also preferably of such character that it is adapted to simultaneously put on a group of the stop-operating members, so that the work of the performer yyil be materially and appreciably simplie With the foregoing general observations I will now describe in detail the structure represented in the drawings. In Fig. l is shown a shaft 2, said shaft supporting for rocking or oscillating movement the bodies of the stop keys 3. When these keys are up as shown by full lines in Fig. 3 they and the stops associated therewith are considered to be off, this being the normal or initial positions of the keys. When the latter are down, however, as shown by dotted lines in said view, they and the corresponding stops, are on. There are Several rollers 4 (Figs. l and 5) supported for oscill-ation at their ends, the forward ends off positions, whereas in Fig. 5 one of them is shown in the position to which it has been shifted to effect the action of the stop connected therewith. The traces 7, 8 and extend through the respective rollers 4. The traces 7, 8 and 9 are shown pivoted to the upper ends of arms 10, 1l and 12 supported for rocking motion on the shaft 13. ln my patent for combination organ stop action, of November 11, 1913, No. 1,078,079 l have shown these stop keys, rollers and traces except as to the trace 7, exactly as already described and shown.

1 Said trace 7 carries a series' ofactuators 14,

y shafts 19' equipped with 'rigid arms'20 and connected by links, as Y21 with the respective rock arms 10, 11 and 12.` Except for the rst plunger 16 and the connections therewith, the construction thus far described is precisely as set forth in said patent, for

which reason they have been only briefly described. f

v Sustained by the shaft 2 which carries the stop keys 3 is a yyoke 22, the side branches of this yoke being perforated for the reception of said shaft and being as represented connected at their forward ends by the cross bar 23 which cross bar vconstitutes what l term a cancellation bar. This bar or its equivalent in the present case is common to and extends over or across several stop-keys or analogous members and has two stages of movement, during one of which it is adapted through the intervention of suitable means, to effect the restoration of one or simultaneously several stopkeys or like devices to their primary positions, while during the second stage of which v it is adapted to operate all the stop members with which it is coperative to effect the action of all the stops. rIhis cancellation bar 23 (see Fig. 3) is normally situated above the stop keys 3, the interval between the bar and keys being such that the bar on the completion of its initial movement or that utilized to restore one or more keys, will be practically against the upper surfaces of the keys which are up. ln other words when'the bar has completed its first stage of movement its under flat surface will be practically in the plane of the upper surfaces of those keys 3 which lare ed. On the second stage of movement of the bar it engages all the keys and swings them down to put into action thestops connected therewith. United to one of the side branches of the yoke 22 is a spring 24, 4the urpose of which is to return the yoke 22 an `therefore the Shanks thereof being pivoted to the trace 7 and the segmental heads 25 constituting -the operative parts thereof. These actuators are in the present case so disposed at all times, that on the advance of the trace 7 or its movement to the right in Fig. l, that the upper portions of the heads 25 of said actuators14 extending above the upper edge of the said trace 7, will engage theupper side bars of any rollers 4 which are shifted, to return said rollers to their original or inoperative positions. ln Fig. 5 a roller 4 is shown as occupying its shifted position. As the trace 7 is advanced, the upper part of the head 25 of the actuator 14 thereon will engage the upper sidebar of the adjacent roller 4 to swing the same over to its original or inoperative relation as shown by dotted lines in said Fig. 5. Should any other of the rollers 4 be in their operative or shifted positions, the actuators 14 on the advance of the trace 7 will return the same to their original positions. As shown the arm 10 to which the trace 7 is'connected is held position when released, by a spring as 26.

ln the `construction shown the trace 7 is advanced by electrical means set into action,v

by the bar 23 on the first stage of its movement and the electrical means for this purpose may vary decidedly. As shown said means comprises the magnet 27, the armature 28 of which is pivoted to the arm 10. The battery 29 is shown as asuitable generator; any other might be utilized as well. From one pole of the battery to one pole of the -magnet the conductor 30 extends, the conductor 31 extending from the opposite pole of the magnet to the post 32 electrically connected with the plate 33 to which is electrically connected the upright clip 34, the side branches of which are resilient and of sufficient power to comparatively tightly hub the arm -35 extending'rearwardly from vthe shaft 36 supported for rocking movement at pending from the shaft 36 is the circuit closer 39, the lower end of which is bowed to ride against the fixed contact strip 40 to which the post 41 is electrically connected,

the conductor 42 extending'from said post and being connected to the `pole of the battery 29 opposite that to. which the conductor 30 already referred to, is connected. The

.op ive -,portion `of the circuit-closing mem- I Iineriber provided 'on its=irear withthe :arcuate extension 43 terminating inthe foot` piece 44, coperati've with the arm 35. Norl vxnally'the circuit closer 39 is'outi'of engagement with the Contact member 40 as "shown in Fig. 2, the cancellation bar 23 at this time being in its original position or that` shown in Fig."3.

It will be assumed Vthat several of the keys 3 are on as shown by dotted lines in Fig. A3. To restore thesel particular keys to their original positions, the vfollowing procedure iwill'be adopted. The organist will move lthe. lcancellation-bar'downward until its under surface is brought practically against the keys which are up or olf, which as will berecalled is the first stage of movement o`f the cancellation bar. During this downward movement of the cancellation 4bar the rear portion of the yoke 22v is elevated, thus lifting the "member 37 and hence tending to :Tharanpbrtion of. said arm is in the ripof theclip 34 and as said arm is thus .lelCL 'the shaft 36 .as it is elevated with the member 37 is simultaneously rocked to throw the bowed portion-of thev circuit closer 39 .against the contact piece 40 to thusclose the described circuit and .therefore effect the energization .of the magnet 27. Then the magnet is energized it attracts its .armature 2.8 to swing the arm -10 to the right and thereby advance the trace 7, the actuators fon. said trace operating against the upper cross bars of any of the rollers 4 that may be in their shifted positions, to ret'urnsaidmllers and hence the keys conn 'ected therewith to their original or oil mi descending movement of the-cancellation bar positions'. During the primary period of A23'ftliecircuit'closer 39 sweeps across the I contact member` 40. It will be understood that when the first stage of movement of the lcancellation bar 23 has been completed, the foot 44Awill .be above .and out .of contact with the arm 35, so that when the carrier or @loser x39 away from the contact 40, toits .original .position and about the time this isre'ache'cl the "foot or abutment 44 will be againstysid arm' 35. I Awish to make it clear'rthat the circuit closer 39 passes oif from the cont-act 40 approximately at the conclusion of the second stage of movement of the bar 23. In Fig. 2 I have .illustrated by dotted lines the course taken by the ac n .win ,be assumed that theprgaaist desiesfto use-all the stops, this event he gives to the bar its complete downward movement, and this bar on the nal part of movement engages all 'thestop keys i3 'swinging themdown to the dotted line particularseriesl What I claim is: j L 'In an organ stop action, the combination of a plurality of stop operating lmembers movable 'from oli' to 011, a device independent of the organ case and 'located to 'be conveniently and directly operated by the hand of the organist during the playing of the organ, and means actuated'by said device for simultaneously returning to off those rstop members which ,are onf S 2.
