GEORGE B. KELLY, OF WEST BOXBURY, ASSIGNOR TO MASON AND HAMLIN ORGAN COMPANY, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN ORGAN STOP-ACTIONS.
Specification forming part of Letters Patent No. 146,686, dated January 20, 1874; application filed November 26, 1873.
To all whom it may conccmt:
Be it known that I, GEORGE B. KELLY, of West Roxbury, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Reed-Organs; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it. X
The invention relates to certain improvements in operating the valve mechanism of reed-organs, with reference to provisions for independently moving respective valves, and conjointly operating all closed valves independently of such as may be open.
The drawing represents a mechanism embodyin g my invention.
Figure 1 shows the mechanism in plan. Fig. 2 is a sectional elevation thereof. Fig. 3 is an end elevation. Fig. A is a front view.
a denotes the wind-chest; b 0, two sets of the reed-cells d 0, two of the reeds. f denotes a long valve closing one set of reed-cells; and g, a similar valve closing another set. The valve f is fastened to the arms h h of two crank-pins, the parts i i of which are pivoted in bearings k 70, thereby forming the pivotpins, by which the valve is hinged, and from one of said crank-pivots i an arm, l, extends, said arm having a crank-projection, m, which, by a link, a, is jointed to a stoplever, 0. The
other valve is, by a similar mechanism, represented by letters I m a, connected to a simi lar stop-lever, 12. By depression of either of these levers, the valve connected thereto is raised to open the mouths of all of the reed-cells controlled by it, each valve being closed by the stress of a suitable spring, q. Each lever 0 p is operated to depress it by a lever, a, fulcrumcd at s, and connected to a stop key or handle. Only one of these levers 1' is shown, the other being similarly arranged to operate the levers, with which other similar valves are connected. When the stop-key is drawn out, the lever-arm 1' assumes a vertical position, depressing the lever beneath it, and opening and keeping open the valve connected to said lever, and by pressing in the key, the move ment of the arm 1* enables the spring qto close the valve, the valves being independently operated by their respective key-stops. Over the levers 0 p is placed a rocker-shaft, a, turning in stationary bearings 22, and having. at one end an arm, 10, which, by a link, 00, is connected to a horizontal arm, y, of a lever, .2, which lever has a vertical arm, a. A pin, 0 extending through a bar, 0 is connected to this arm a and in front of the head of this pin is a projection, d, from a hinged kneestop, 6 Extending from the rocker-shaft a are fingers or pins f each lever 0 12 having one of these fingers extending over it. The pins f are pressed up normally by the levers 0 p,- but by moving the knee-stop 0 against the pin b the lever-arm y is depressed, the arm '10 being thereby drawn down, turning the rocker-shaft, and forcing the pins f down against the levers 0 p, depressing said levers, and thereby opening all of the valves f g. If either of the valves is already open (by the action of its key-stop lever) such valve will, of course, not be operated by the finger f ex tending over its key-stop lever, and when the knee-stop is released any valve previously opened by its keystop lever remains open, the knee-stop connection insuring the opening of all of the valves, but only having direct action or connection with those valves not already opened by the key-stop levers, the closing valves being closed by the action of the springs q, and not by the action of the fingers and any valve held open by its lever 1' being held open entirely independently of the knee-stop connections. Through the kneestop rocker or roller u, and its pins f arranged to act upon all of the unopen valves, a full organ effect may be at any time produced, or a swell action, and this without disturbing the position or action of such valves as may have been opened for special efi'ects, such valves remaining open when the pressure upon the knee-stop is released to permit the others to close.
I claim- 1. In combination with the valves, the le= shaft with the knee-stop 0 substantially as shown and described.
Executed this 4th day of October A. D. 1873.
GEO. B. KELLY.
