COMBINATIO N ORGAN STOP-ACTION.

SPECIFICATION forming part of Letters Patent No. 416,158, dated Qecember 3, 1889.

Application filed August 17, 1888. Serial No. 282,962. (No model.)

T to whom it may concern.-

Be it known that I, SALLUSTE DUVAL, of Montreal, Quebec, Canada, have invented a new and useful Improvement in Stop-Actions for Organs, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

The object of my invention is to produce a mechanism by which the organist can immero diately and simultaneously bring into effect any stop or stops previously selected, while at the same time all other stops are drawn in or left untouched, all depending upon the previous setting of the mechanism, the entire operation being accomplished by a single movement, while all stops are free to be operated in the usual way, excepting only at such time as the mechanism in question is in operation. I accomplish this result preferably by mechanism having for each combination pedal, piston, or movement a separate pedal, piston, or movement to do the setting of the stops to be drawn 011, off, or left untouched, after the desired selection has 2 5 been arranged or selected, by moving the stopknobs themselves in the'usual way, all operating in connection with the mechanism of the stop prepared.

My invention will be readily understood from the accompanying drawings, in which- Figure 1 represents a general elevation, partly in section, of my mechanism; Figs. 2, 3, 4, and 5, views of my stop-moving mechanism in different positions; Fig. 6, a rear ele- 3 5 vation of the stop moving and setting mechanism; Fig. 7, a view of a detail of the mechanism by which the individual stops are operated, and Figs. 8 and 9 views of a modification of the setting mechanism.

In my drawings similar letters refer to similar parts.

D D D D represent some of the ordinary stop-handles of an organ.

A A A A represent the stop-rods controlled by these handles. These rods operate pivoted levers B B B B as shown, which in turn operate the sliding stop-rods O O O C the upper ends of the levers B B B B being flattened and operating between nuts or connected in any other suitable way. These sliding stop-rods O O C C control the stopaction, the stops being thrown on when the handles D D D D are drawn outward, thereby moving inward the sliding stop-rods O C O 0 By my invention I can draw 011 any number of these stop-rods by a treadle, having determined in advance which of them I shall so operate, and I can simultaneously close all'the other stops by the same movement. This I do in the mechanism shown by means of two foot-ireadles T T and intermediate mechanism, to be described. I can likewise, by the devices shown in Figs. 8 and 9, draw on such stops as I have determined upon, close such other stops as I have determined upon, and leave the remaining stops in the position in which they may be at the time of the setting operation.

In order to accomplish the result desired, I make use of the following mechanism: Each 7 sliding stop-rod O O O (J is provided with an independent rocker n for each combination pedal or piston. It is of course understood that the sliding stop-rods O O O O are arranged parallel to each other, as shown in Fig. 7, and in the same horizontal plane, whereas the stop-handles, if desired, may be one above the other in the usual way. These rockers H are pivoted at or about their middle in some suitable way. As shown, a pin passing through a suitable slot enters the sliding stop-bar, allowing the rocker n to as sume the two positions shown in Figs. 2 and 3. As shown, the lower surface of the rocker is not flat, but the two planes meet at an obtuse angle. Fastened in slots or other suitable way at the two ends of the rocker a are the controlling-pins Z and m, having heads y, whereby they can be moved by the operation of the rocker. The rocker itself is frictionally held in either position to which it may have been moved bysprings o 0'. The arms a are caused to rock by means of the rod I, placed over them, and which can be forced down upon either end or upon the middle of the rockers, depending upon the position of the stop-rods. This sliding pusher t moves up and down in the slots II in the side frames of the mechanism. It is depressed by two rods 1* e, which are attached to arms at an angle to each other, which project from the long roller or axis 7'. The bell-crank 51:, Fig. 1, can be thrown to the right, thereby drawing down the rods 2' when the bell-crank s is raised, thereby moving backward the connecting-bar 'u: The bell-crank s is operated by the t-readle T in the wellknown way,which treadle may be raised by a spring. If, now, the handle D is pulled out, the sliding stop; rod 0 will be in the position shown in Fig. 3, and if the pusher t be depressed it will change the position of the rocker n, moving it in the position shown in Fig. 2. If, on the other hand, the handle D is pushed in, the relation of the pusher t and the rocker n will be as shown in Fig. 5 in full lines, and when the treadle T is operated the motion will be that shown in dotted lines in Fig. 5, depressing the inner end of the rocker n and moving it in the position shown in Fig. a. It is of course obvious that this motion of the rockern alternately depresses and raises the pins Z and m, which are the determining m echanism upon which the automatic stop-mov in g apparatus operates. This automatic stopmoving mechanism consists of two vibrating bars or wipers 7;. f, extending across all of the stop-rods to be effected, and held by arms proj ectin g from rollers or axis of suitable length, 2) and e, which are pivoted at their ends, as shown. These vibrating bars or wipers are operated by the treadle 'l". When this treadle T is depressed, (being ordinarily raised by a spring,) the connecting-rod a is raised, thereby elevating the lower arm of the bell-crank b, which then forces to the right the connecting-rod c and the lower arm (1 of the roller (2, which operates to throw the arms f to the left, Fig. 1; but this motion likewise throws backward the arm g, attached to c and d, and therefore forces the connectingrod h to the left, and therefore depresses the arm j, and therefore forces the arms 7; to the rightthat is, the depressing of the treadle T brings these vibrating wipers into the position shown in Figs. 2 and 4, while the release of the treadle allows them to separate, as shown in Fig. 3. Under these circumstances it is obvious that if the wipers are brought together all the stop-rods C C C C which have their right-hand pins m depressed will be forced outward, whereas all those which have their left-hand pins Z depressed will be forced inward. This operation is shown in the movement of the stop-rod G from its position in Fig. 3 to its position in Fig. 4 by the action of the wiping-arm f against the pin m. Similarly the stop rod C, Fig. 1, would be moved to the position shown in Fig. 2, if the rocker n were in the position -there shown and the treadle T were de- F, and is again out out to a depth at G. The push-bar t is likewise somewhat broader than that shown in Fig. 1. If, now, the stoprod (3 be half pulled out and the treadle T be operated, then the pusher '6' will be depressed into the position shown in Fig. 8, thereby leaving the rocker n in an intermediate position with both the pins Z and on raised so as to not be affected by the wipers. The spring E is so shaped as to retain the rocker n in this intermediate position. If, on the other hand, the stop handle .1) is pulled out, thereby pushing the stop-rod C in, and the pusher t be depressed, the operation will be as shown in Fig. fl, depressing the left end of the rocker 9t. On the contrary, if the stop -handle D" be pushed ontirely in, the operation will be to depress the right-hand end of the rocker 4'1. and lower the pin on.

It is obvious that a pneumatic or other action may be substituted for the pedal action, as shown.

It is to be noticed that an important part of my invention is in the fact that the setting or preparing of the stops for future movements is determined simply by the position of those stops.

I am aware of the patent granted to H. L. Roosevelt, July 28, 1885, in which an independent setting. mechanism was employed for each stop, so that the operator, in addition to operating the determined stops at the desired time, had, by a mechanism independent of the stops themselves, to determine in advance which of the said stops were to be operated.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in an organ-action, of mechanism for moving several stop -bars simultaneously and mechanism connected with said stop-bars capable of being set, by which all the stops previously determined upon can be thrown into or out of action simultaneously, the said setting mechanism being set to Withdraw or advance the stop-bar, depending upon the position of the stop-bar itself at the time of the setting operation, substantially as described.

2. The combination, with the parallel stopbars of an organ, of a series of pins capable of being set in two positions, the said positions being determined by the position of the stopbar at the time of setting the pins, and mechanism for simultaneously moving all of the pins which have been set in the same position, substantially as described.

3. The combination, with the stop-bars of an organ, of two pins for each stop-bar, one for moving the stop-bar inward and one for moving the stop-bar outward when set, a setting mechanism depressing one or the other of said pins as the said stop-baris drawn in or out at the time of the setting, and two vibrating bars or wipers for simultaneously moving ICO in or out the bars upon which the pins have been correspondingly set, substantially as described.

4. The combination, with the stop-bars of an organ, of two pins for each stop-bar, one for moving the stop-bar inward and one for moving the stop-bar outward when set, a setting mechanism depressing one or the other of said pins as the said stop-bar is drawn in or out at the time of the setting, a rocker upon each stop-bar for setting the pins, and two vibrating bars or pushers for simultaneously moving in or out the bars upon which the pins have been correspondingly set, substantially as described.

5. The combination, in a stop-setting mechanism, of the stop-bars C the rocker a, rocking thereon, the pins Z m, and the Wipers f k, and the pusher t, and mechanism for operating the same, substantially as described.

6. The combination, in the stop -setting anism being both controllable by the operator at the key-board, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SALLUSTE DUVAL.
