Specification of Letters Patent.

3, 1911. Serial No. 642,196.

To all whom it may concern.

Be it known that I, JOHN T. Aos'rnv, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Organ-Valves, of which the following is a specification.

This invention is an improved valve for use in organs, and other instruments wherein simplicity and lightness of. construction,

ease and rapidity of operation, and fiexibility of action are desirable.

Figure l is a side view partly in section of portions of an organ embodying this improvement. Fig. 2 is an end view projected from Fig. 1. Fig. 3 is a sectional side view showing the valves of Fig. 1 and their operation more in detail. Fig. 4; is a plan view of one of the valves projected from Fig. 3. Fig. 5 is an end view, projected from Fig. 3,

showing in addition a modified form of the valve.

This is a division of my application Serial No. 246,883,1iled Feb. 20, 1905, for improvements in organs.

The drawings show the environmentof these valves to a suiticientextent to enable their construction and operative relations to be understood.

so In the embodiment of the present invention herein shown, the valves are appurtenant to the pipe bars 26, which support the organ pipes of the different stops or registers, these pipe bars in this instance formin apart of the upper wall of the ceiling o the wind chest. The pipe ducts 29, through which the air from the wind chest passes to the respective pipes, extend through these pipe bars, which are provided with stop slidto ers 30 or other suitable devices for drawing the respective stops or registers off and on.

The valves which form the subjectmatter of the present invention are employed for opening and closing thelower ends or the pipe ducts. Each valve consists of a pallet 7 carried by an integral piece of wire, bent to form the various limbs and members, comprising the eye 77, the pallet arm 76, the hinge or pivot member 78, and the operating or trace arm 79. These parts may be disposed in any desired relation. As herein shown, the two arms stand nearly at right angles to each other, joined by the pivot member 78.

formed of a layer of felt 74:, with a layer of leather 73 cementedor otherwise secured to each side of it (Fig. 3 and is attached to the pallet arm 70 concentrically with the eye 77 of the pallet arm, which is disposed in a plane suitable for supporting the pallet in proper relation to its duct. Although the round form of eye 77 is generally preferable, it is obvious that triangular or other forms of seat may be employed. For convenience lIl locating and hinging these valves in their correct position relative to the ducts, the pivot portions or members 78 are seated in saw kerts or grooves 86 in the under side of the pipe bars 26 at a suitable distance from the ducts to insure proper registration of the pallets with the ducts. In order to enable the pivot portions 78 of the valves to seat securely and yet oscillate freely in the grooves 86, the arms 76 and 7 9 extend in the same plane from the pivot member until clear of the groove, and then diverge to their desired angular relation; in thisinstance the grooves, being most conveniently cut in the under faces of the pipe bars, face the general direction of the operating arm '79. Therefore'that arm may, as herein shown, extend from the pivot member without any bends, while the pallet arm 76, after extending in the plane of the operating arm 79 far enough to clear the groove, is bent at 72 substantially at right angles to the arm 79 and approximately parallel with the under surface of the pipe bars. lVhere only a slight rocking motion of the valve is required, as in the present instance, an ordinary saw kerf, wide enough to allow the pivot member to seat freely, will generally be wide enough to allow of the required oscillation. of oscillation of the valve is desired, the sides of the groove may be made flaring, either throughout their entire length, or at the location of the arms, to a suthcient extent to allow the desired freedom and amplitude of movement of the valves.

The pivot portion 7 8 of the valve is retained in place in the groove by buttons or clips 80, which are attached to the under side of the pipe bars 26 by screws 81 or in any other convenient way. These clips may be held against turning edgewise by a wire Obviously, where a greater degree or spline 82'- seated partly in the clip and I The pallet 7 5 is preferably partly in asaw kerf or grooveinthepipe The lower en parallel with the groove 86.

s of the arms 7 9 of the valve levers are bent or otherwise pivotally con nected at 88 with the trace or tracker 83, which connects together the valves for the same note in the different stops or registers, as illustrated in Fig. 1. These traces 83, one for each scale note, are connected'either directly or indirectly by means of mechanical or pneumatic sf'ftems so as to be operated by the keys of a keyboard or the perforations of a note sheet in any well-known 'way. In the present instance they are shown to be connected by means of a rod 85 with a motor pneumatic 116 attached to a side wall of the wind chest and connected by means of the air passage 113 with any suitable relay device, like those, for example, which are shown in my original application above referred to, of which this is a division. In any case, the endwise movement of the trace 83 opens and closes the ducts 29 in the respective pipe bars, the open and closed positionsof the valve being shown in Fig. 3.

The pneumatics 116 may be operated either by pressure or vacuum systems. The return movements for closing the valves are preferably elfected by means of springs either within the pneumatics themselves or attached 'to any convenient portions of the traces 83:

This wire construction of the valve has many desirable advantages, especially for pneumatic actions of the character described. Being very light, they respond promptly to the key action. Each lever carries its own pivot or journal member, which may be seated in any suitable groove adjacent to its desired position. Either or both of the wire arms may be easily bent to any desired relation with each other, or to the respective parts with which they are connected; and in the type of organ illustrated therein, their open and-accessible disposal enables them to be observed and adjusted by an operator within the wind chest, while the organ is in full operation under normal pressure. The Wire also has a certain amount of spring in itself, so that it forms a spring return cushion which 'materially aids the repetition of the action in rapid passages. This springing property also causes the pallet to leave its seat faster than the normal speed of the action. since the airpre'ssure which holds the pallet against its seat must first be overcome before the pallet will move. The valve arms will therefore yield until this pressure is OVBIOIIIG and the pallet will then be carried away from its seat at an increased rate of speed, due to the combined action of the bar, extending movement of the trace and the recovery of the spring in the valve arms. The full v0lume and pressure of air will therefore be admitted to the organ pipe more suddenly than would take place with a more gradual opena grooved pivot sea ing of the valve, and the initial quality of the tone will be thereby improved. The spring property of the valve also permits the pressure on the back of the pallet to close the duct opening tightly even if a slight misadjustment of the valve or the action should tend to prevent such closing.

In some instances it is found desirable to employ two ducts leading to the same pipe, instead of employing a single, larger duct, dividing the required duct area between two ducts, thus enabling two smaller valves to be used instead of a single large valve. In such instances the two valves are connected together for simultaneous operation, as illus trated in Fig. 5. The two valves 126 and 127 are provided with separate pallets, each covering a duct as illustrated in the previous figures,.the difference being that the oper ating arm of one valve, in this case 127, is

connected with the corresponding arm of the valve 126, so that both are operated. by the single trace 128, which thus moves both of the valves. 126-and 127 simultaneously.
