IMPROVEMENT IN REED-ORGAN STOP-ACTIONS.

Specification forming part of Letters Patent No. 175,253, dated March 28, 1876 application filed February 18, 1876.

To all whom it may concern Be it known that I, ROBERT G. NIoHoLAs,

of Indianapolis, county of Marion, State of Indiana, have invented a new and useful Improvement in Stop Action'for Organs, of which the following is a description, reference being' had to the accompanying drawings.

My invention relates to themanipulation of the stops in an organ, whereby I obtain a more ready control over them than heretofore; and it consists in the construction and arrangement of cranks, treadles, levers, and connecting-rods, connected with upright rods and stops, as hereinafter more fully described and set forth in the claims hereto annexed.

Figure l represents a plan view-of the upper stop-section of an organ embodying my improvement. Fig. 2 is a plan View of the lower or bellows section of the same.

The cabinet-case of the organ is represented at A, at the front of which, near the bottom, as shown in Fig. 2, are arranged the treadles VV1,W2,W 3, W4, and W5. All of these treadles except W4 (which may be duplicated if required) are hinged or pivoted in the usual manner to the base of the organ. The treadles W4 are pivoted with and attached to f the arm G1, which is also attached to the shaft G4", said shaft being arranged to partially rotate in the bearings E2 E3. The shaft G2 is provided at the inner end with a crankarm or lever, G4, which extends upward and makes connection with the rod N2, which is also provided with a pivoted lever, N1, the action of which will be hereafter more fully described. The rod G3 is also attached to the shaft G2, as shown, and extends back, and the rear end, which is provided with a fork, is arranged to operate on the stud y of the upright square rod D, which moves up and down in square sockets formed in the guides B5. The action of this part will hereafter be fully explained.

The treadle W3 has one end of the connection-rod Oz pivoted at X. The rod O2, extending back and to the rear end, is pivoted to the lever N4, which has one 'end attached to the round upright rod C, which partially rotates in the bearing B3, the operation of which will be hereafter described.

Near the central part of the front of the organ, between the treadles W5 and W2, is also a round upright rod, O3, which partially rotates in the bearings formed or attached to the bottom of the organ and to the inside of the front part above the bellows.. To this round rod C3 is attached a lever, N3', which is also pivoted to the front end of the connecting-rod O1. To the rear end of this rod O1 is also pivoted anotherlever, N5, which in turn is attached to the upright round rod O1, which partially rotates in the bearing B4, as shownk in Fig. 2.

The square upright rod D extends upward through the guide B near the upper section, as shown in Fig. l, and has the lever F pivoted to the upper end. This lever F is attached to the partially-rotating shaft G, which is supported above the stops R by the bearings E E1. At the inner end of the shaft G is also attached the lever L, (an end view only being shown.) This lever extends downward and is pivoted to the connecting rod H, which in turn is pivoted to the stop-sliding bar P, which is arranged above the stops R R at the rear of the frame S, and is operated, by means ofthe treadle W4 and its connection, to move back and pull the stop R by means of the pins 7L h arranged in the stops R at the rear lof the slide P, as shown. The round upright rod G1 can be operated by the same treadle, W4, by having the lever Nl connected therewith, which would cause a partial rotation of the rod G1, which also extends up above the stops R, and is provided with the lever N near its upper end, which lever connects with the connecting-rod O, that is pivoted at the other end with the4 stop-slide Q at r, as shown. By pressing down the treadle W4, it would cause the slide Q, by its connecting-levers and rods, to be moved forward, which, acting against the other set of pins g g of the stops R, would move the stops forward, and at the same time the pins h h at the rear of the slide P would move said slide forward. If the tread-le W4 is connected with the upright rod G1, then the connecting-rod G3 or F should be disconnected from the square upright rod D, and if the treadle W4 is connected with the square rod l), then it should be disconnected from the rod U1, the object being' to get two motions, one the opposite of the other, by the same treadle.

The upright round rod C is provided at the upper end with a rod, M, one end of which is formed with a hook which hooks around the pin M', that is attached to the bar K, which unites and operates any two or more stops R, by means of the pivoted connection-ties or rods J J', the rod G being operated, with its connections, by means of the treadle W3, as shown. The upright rod Cl being connected with the stop slide Q, as before described, is also operated, by means of the knee of the performer, to throw the stops in or out, as required. To accomplish this movement, the upright rod C3 is used at the front of the organ. The upper end oftliisrod is provided with alever, U, the outer end of which is connected with the hinged lever V at U', as shown. Any move ment of the knee that would force the hinged lever V toward the organ will partially rota te the rod U3. and by its connection with the stop slides Q will move it back, together with theslidesP, or forward it' the reverse motion is given to the hinged lever V by the knee. The slides P and Q are united together by the cross-slides T T', which operate on wires or rods u u, as shown. By these arrangements of stops, I obtain a more complete control of the different tones of the organ than heretofore and a greater variety of changes, which are necessary to a complete organ.

What I claim as new, and wish to secure by Letters Patent, is`

l. In` an organ, the combination of the treadle W4, rod G1, shaft G2, rod G3, square upright rod D, lever F, shaft G, lever L, pivoted connecting-rod H, and stoplslide P, arranged as shown, for the purpose specified and set forth.

2. In an organ, the combination of the treadle W4, rod G1, shaft G2, lever G4, connecting-rod N2, lever N1, round upright rod C',

'lever N, pivoted connecting-rod 0, and stopl slide Q, arranged as shown, for the purposes specified and set forth.

3. In an organ, the combination of the hinged lever V, slotted lever U, round upright rod U3, lever N3, pivoted connecting-rod O1, lever N5, round upright rod G1, lever N, pivoted connecting-rod O, and stop-slide Q, arranged as shown, for the purposes specified and set forth.

4. In an organ. the combination treadle W3, connecting-rod O2, lever N4, round upright rod C, hooked arm M, pin M', connecting-tie K, connecting pivoted bars J J', and stops R. arranged as shown, for the purposes specied and set forth.

5. In an organ, the combination of the stopslides P Q., cross-slides T T', slide-rods u u, stops R, and pins h h g g, arranged as shown, for the purposes set forth and described.

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

ROBERT C. NICHOLAS.
