ORGAN STOP-ACTION.

Specification of Letters Patent.

Patented A11 24:, 1915.

Application filed December 23, 1914. Serial No. 878,814.

To all whom it may concern Beitknown that I, MALCOLM S. PITT, a citizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Organ Stop-Actions, of which the following is a specification.

My invention relates to improvements in organ stop actions, and 'more particularly to improved means for changing the registration of'pipe organs, the object of the invention being to provide an arrangement of auxiliary stops or other auxiliary devices equal in number to the number of organ stops, and which can be operated while playing and provide improved means for positioning the organ stops in conformity with the position of'the auxiliary stops at a single operation. Y

In playing'many different pieces of music on the pipeorgan, it is necessary to change the" registration from time to time. Frequently this means a-complete stop of the music for'an awkward length of time, and requires the operator to-hastily pull out certain stops and push in other stops, more or less marring the effect of themusic.

It is the purpose'of my invention to provide an improved arrangement of auxiliary stops which can be operated while playing, and when thetimearrives for changing the registrationby the operation of a foot leveror levers, or other device, the organ stops can be simultaneously moved to conform to the position of the auxiliary stops, thereby instantly changing the register without any appreciable loss of time, and without any extra'exertion on the part of the operator.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a fragmentary view in front elevation of an organ, illustrating my improvements. Fig. 2, is a fragmentary view in vertlcal section taken on the line 2-2 of Fig. 3. Fig. 3 is a fragmentary view in horizontal section'on the line 3-3 of Fig. 1, and Fig. 4 is a fragmentary view in vertical section on the line 4-4 of Fig. 3.

1 represents an organ or more particularly an organ console provided with stops 2 controlling the ordinary mechanism of the organ. My invention is not limited to any particular number or arrangement of these stops. For convenience of illustration I have shown nine stops at each side of the organ keyboards 3, and above the upper keyboard 3 I locate my improved auxiliary stops 4, but it is to be'understood that the number and location of these organ stops and auxiliary stops may be variously arranged without departing from my invention.

In the illustration, the stops 2 at theright of the organ, are in combination with the upper keyboard 3, and the stops at the left of the organ are in combination with the lower keyboard 3. The auxiliary stops t above the upper keyboard are divided into two series, the series at the right controlling the stops 2 atthe right, and the series of auxiliary stops 4 at the left controlling the stops 2 at the left. As the series of stops at the right and left of the organ are operated in precisely the same manner by the auxiliary stops, it is only necessary to illustrate and describe one set or series of such stops, and for convenience of illustration,

5 with slots 6 therein, and blocks 7 fixed thereto. Bars 8 are supported in the organ casing 1, and are located parallel to the stops 2. These bars 8 are mounted to slide longitudinally, and throughout a portion of their length are angular in cross section and correspond in size and shape to the angular portions 5 of the stops 2.

It is to be understood that each organ stop 2 is provided with a bar 8, and each bar 8 has a slot 9 therein and is provided on its upper face with a cam block 10. Through the slots 9 of the "bars 8, levers 11 are positioned and are pivotally supported between their ends in the slots 9 by means of transverse pins 12 projected thr'ough'the bars and the levers. These levers 11, at their free ends, are located in the slots 6 of the stops 2, and it will be noted that these slots 6 are of a length to allow a considerable movement of the levers therein without moving thestops.

For moving the levers 11 of each vertical series of bars 8, I provide a pair of vertical parallel swinging gates 13. The pairs of gates 13 are pivotally mounted on fixed horizontal bars 14, and the gates of each pair are connected by links 15 to compel them to swing together. As the pairs of gates and their operation are precisely alike, the description of one will apply alike to all.

The inner gate 13 is adapted to engage the levers 11 of the vertical series of stops which they control, and the forward gate 13 is provided with a pivoted arm 16. This pivoted arm 16 is adapted to engage the block 7 of stop 2, unless prevented by the cam block 10 on bar 8, as will be more fully hereinafter described.

To compel the pairs of gates 13 at one side of the organ to operate simultaneously, I provide a longitudinal shaft 17 supported in suitable bearings 18, and provided with. upwardly projecting crank arms 19. The arms 19 are connected by links 20 with the rear gates 13 of the series, so that when the shaft 17 is turned, it compels all of the gates at one side of the organ to swing simultaneously.

21 is a foot lever held in normal position by a coiled spring 22, and connected by a link 23 with a crank arm 24 on shaft 17. When this foot lever 21 is operated, it will cause all of the gates to swing in a rearward direction, and when pressure on the foot lever is released, the spring 22 will return the parts to normal position. I have shown two of these foot levers 21, but it is of course to be understood that the entire operation may be by a single foot lever if desired.

The bars 8 above referred to are caused to move longitudinally by means of the auxiliary stops 4, and while I have illustrated these bars as having cylindrical forward ends 25, movable in cup shaped guides 26, it is to be understood that this particular form of mounting may be varied as desired. Each bar 8 is provided with a slot 27, and a bell-crank-lever 28 is provided for operating each stop. Brackets 29 support the bellcrank-levers 28, and rods 30 connect the bellcrank-levers 28 with crank arms 31 on vertical shafts 32. These shafts 32 are supported in brackets 33, and are connected by crank arms 34 with the auxiliary stops 4.

By reference particularly to Fig. 2, it will be seen that the various rods 30 are at different elevations, so that there is no conflict of the parts in their operation. It will also be noted in Fig. 2, that the angular portions 5 of stops 2, and the angular portions of the bars 8, are so arranged that the pivoted arms 16, although at an angle, rest upon smooth surfaces of both the bars and the stops.

It is to be understood that it is my intention to provide felt pads 35 throughout the construction wherever twoparts come together, and are liable to create noise, and I may variously arrange the cooperating parts to conform to the particular instrument.

The operation is as follows: At the beginning of the performance, certain stops 2 are drawn out in the ordinary manner. As the performer plays the first part of the music, he can at opportune times, draw out the auxiliary stops 4 in accordance with the first change in the arrangement of stops, and when the proper time of change occurs, he can depress the foot lever or foot levers 21, and compel stops 2 to take positions corre sponding to the positions of their respective auxiliary stops. If the stop 2 is drawn outward, and the auxiliary stop for such organ stop is drawn outward, the bar 8 will be drawn forward or outward so that its cam block 10 will elevate the pivoted arm 16, permitting it to move rearwardly as the gates 13 are swung without striking the block 7. At the same time, the rear gate 13 will engage lever 11 and force the bar 8 to its inward position. This inward movement of the bar 8 returns the auxiliary stop 4 to its normal inward position.

If the organ stop 2 is in its inward position, and its controlling auxiliary stop 4 is drawn outward, the operation of the foot lever 21 will compel the parts to move as follows: As the auxiliary stop 4 has been drawn out, it will cause the bar 8 to move forwardly, thus bringing the end of the lever in position to be engaged by the inner gate 13, so that as the latter swings inwardly, it will compel the lever 11 to swing on its fulcrum, and move the organ stop to a forward position. If the organ stop 2 is out, and its auxiliary stop is in, the operation of the foot lever will cause the gates 13 to swing, and the pivoted arm 16 will engage the block 7 and force the organ stop inwardly, as the block 7 will be in a forward position, and the operation of the arm will not be interfered with by the cam block 10. If the organ stop 2 is in, and the auxiliary stop 4 is in, the operation of the gates 13 will not affect the parts in the slightest, as they will be in the position shown in Fig. 2. After the operation of the gates by the lever 21, such auxiliary stops 4 as are drawn outwardly, are manually forced inwardly, and a new combination set up when desired.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
