Specification of Letters Patent.

Application filed February 14, 1906. Serial No. 361,011.

T o all whom it may concern:

ie it known that l, Hman EUGENE CHUTE, a citizen of the TJnited States, and a resident of Peru, in the county of Miami and State of Indiana, have invented a new and improved Operating Mechanism for {eed-Organs, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in operating mechanism particularly adapted for use in reed organs for controlling the notes of the organ, the octave coupler, and the like, and resides in the arrangement of this mechanism, whereby the desired movement of said parts may be obtained andy controlled by the treadle of the organ.

rI "he invention involves various other features of major or minor importance all of which will be fully set forth hereinafter and pointed out in the claims.

Reference is had to the accompanying drawings which form a part ofthis specification, in which drawings like characters of reference indicate like parts in the several views, and in which Figure 1 is a section of an organ provided with my improved operating mechanism; Fig. 2 is an enlarged sectional view illustrating a part of one of the keys and the octave coupler in connection therewith; FiO'. 3 is an enlarged sectional view illustrating the two controllable reeds and the stops therefor; Figs. 4, 5, and 6, are elevational views illustrating various positions taken by the octave-coupler treadle; and Figs. 7, 3 and 9 are similar views illustrating the action of one of the stop treadles.

In the drawing applicants invention is shown in connection with an organ provided with the usual pumps or bellows 15, treadles 16 for operating the bellows, the suction box 17 the foundation reeds 18, the auxiliary reeds 19 and 20, the valves 21 controlling the communication between the reeds and the suction box, and operated from the keys 22 through the medium of pins 23, the valve 24 for permitting the passage of air through the reeds 18, the valves 25 and 26 for controlling the reeds 19 and 2O respectively, the octave coupling levers 29 and the swinging supports 30 carrying said levers.

The invention consists of treadles and connections especially adapted for operating shaft 33.

the valves 25 and 26 controlling the auxiliary reeds 19 and 20, and a treadle 31 and connections for operating the swinging carrier 30 controlling the octave coupler levers.

is best shown in Figs. 4, 5 and 6, the octave coupler treadle 31 is articulated at its inner end with a vertically extending bar 32 having shoulders 33 and 34 on its upper portion. Said shoulders 33 and 34 are arranged on opposite sides. bove the shoulders 33 and 34, near the upper end of the bar, a shoulder 36 is formed at the same side on which is located the shoulder 34. Inclosing the bar and lying above the shoulders 33 and 34 is a loop 37 fastened rigidly to a rock To this rock shaft is also fastened a crank arm 39, the crank arm 39 carrying pivetaily a link 40 which extends upward and has its upper end pivotally connected to an arm 41 on a rock shaft 42 mounted in the framing and having one or more arms 43 connected with the swinging carriers 30 so that upon the operation of the rock shaftthe carriers will be caused to take the position shown by the dotted lines in Fig. 2, thus throwing the octave coupler levers 29 into the path of the projections 44 on the keys 22.

Referring particularly to Figs. 4, 5 and 6, the operation of the octave-coupler-treadletrain may be traced as follows: Parts normally lie as shown in Fig. 4. Upon depressing the treadle the bar 32 is raised causing the shoulder 33 to rock the loop 37 and the rock shaft 3S and throw the parts 39 and 40 into the position shown in Fig. 5, in which position the coupler-lever-carrier 30 will be raised as shown by the dotted lines in Fig. 2. Upon releasing the treadle the parts 31 and 32 will under the action of a spring 45 return to the position shown in Fig. 5. To release the octave coupler and to permit the parts to return to normal or inactive position, a second movement of the treadle 31 should be effected thus bringing the parts to the position shown in Fig. 6 in which the shoulder 36 strikes a part of the framing of the organ and limits the upward movement of the bar 32, and the shoulder 34 strikes the loop 37 and throws the sameover to the other side of the center of the rock shaft 3S as Fig. 6 illustrates, then upon'releasing the treadle the bar 32. drops to the position shown in Figs. 4 and 5, and the link 40 and crank 39 are thrown down by gravity to the normal or inactive position. It will be all ' attachments. pin against which the en'd of the bar 46 seen, therefore,'that a single movement of the treadle throws the octave coupler into action and retains it in active position until it is desired to release the octave coupler, whereupon a second movement of the treadle is effected and the parts are released as described.

The treadles and their connected trains for operatingthe valves 25 and 26 and controlling the reeds 19 and 20 are similar to each other, and one, for examplethe treadle 28 for operating the valve 26, is illustrated in Figs. 7, S and 9. To the said treadle a vertically extending bar 46 is pivoted, this bar having at its upper portion shoulders 47 and 48 on opposite sides. rIhe bar 46 is at its upper portion received in a loop 50 rigidly secured on a rock shaft 5l similar essentially to the rock shaft 8S. The rock shaft 5l carries a crank arm 52 to which a link 53 is joined (see Fig. l). This link is connected at its upper end to an arm 54 which is attached to a swinging carrier 55, which is in turn connected with the valve 26 commanding the reeds 20. Upon depressing the treadle 27 the bar 46 will' be moved upward, causing its shoulder 47 to engage the loop 50, and rocking the shaft 51 so as to throw upward the arm 52 and through the medium of the parts 53, 54 and 55 raising the valve 26 admitting atmospheric pressure to the reeds 20. The parts will stay in this position excepting that the treadle and bar 46 will drop to the position shown in F ig. 8. 'Io release the rock shaft 5l and allow the valve 26 to close a second movement of the treadle will be effected, causing the shoulder 48 to engage the loop 50 and throw the rock shaft back (see Fig. 9) the same as described in connection with the treadle 31 and its 56 indicates a stop screwor may contact, and 57 indicates a spring similar to the spring above described.

Various changes in the form, proportions and minor details of my invention may be.

resorted to at will without departing from the spirit and scope thereof; hence I consider myself entitled to all such variations as may lie within the terms of my claims.`

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent:

l. In combination, a controllable part, a rock shaft in connectiony with said controllable part, said rock shaft having arms lying at opposite sides of the axis thereof, a movable member having shoulders respectively adapted to engage said arms ofthe rock shaft, means for operating said movable member, and the said movable member also having a shoulder at its upper extremity and a stop adapted to' be engaged by said shoulder to limit the movement of the movable member.

Q. In combination, a part adapted to be controlled, a reciprocating member, said member having shoulders at opposite sides thereof, means for operating the member, means adapted to be alternately engaged by said shoulders and having connection with said part adapted to be controlled to operate the same, said reciprocating member also having a third shoulder at its upper eX- tremity and a stop adapted to be engaged by said shoulder. v V

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