'7 Claims.

My invention relates broadly to electric valve actions and more particularly to an electrically operated organ valve.

One of the objects of my invention is to provide a construction of electrically operated organ valve which is capable of inexpensive quantity production and assembly.

Another object of my invention is to provide a construction of electrically operated organ valve which comprises a bracket having a multiplicity of mounting means for electric valve actions in which the magnetic paths for each of the magnetic systems are maintained substantially independent and capable of variously operating any one of the valves in the multiple system.

Still another object of my invention is to provide a bracket mounting for a multiplicity of magnetic valve actions having bearing means for each of the valve actions, the bearing means being so arranged that the magnetic armatures may be readily positioned with respect to the bracket mounting for individual functioning by magnets carried by the bracket.

A further object of my invention is to provide an arrangement of bracket mountings for a magnetic valve action in which a magnetic core member is supported in the bracket, an angularly movable armature pivotally mounted with respect thereto and resilient means disposed between the mounting for the armature and a tongue which extends from the end of the magnetic core of the operating magnet whereby the entire system functions as a unit for controlling an electric valve action.

Other and further objects of my invention reside in the construction of electric valve action set forth more fully in the specification hereinafter following, by reference to the accompanying drawings, in which:

Figure 1 is a vertical sectional view through a fragmentary portion of the pressure chamber of a reed operated organ, showing the electric valve action of my invention arranged in position in side elevation; Fig. 2 is a vertical sectional view through the electric valve action of my invention taken substantially on line 2--2 of Fig. 1; Fig. 3 is a top plan view of the electric valve action of my invention; Fig. 4 is a cross-sectional view through the electric valve action, taken on line 4-4 of Fig. 1; Fig. 5 is a transverse sectional view through the electric valve action on line 55 of Fig. 1; Fig. 6 is a sectional view taken substantially on line 66 of Fig. 1, with parts shown in front elevation; Fig. 7 is a transverse sectional view through the electric valve action on line 11 of Fig. 6, showing the electric valve action in de-energized condition with the valve closed; Fig. 8 is a view similar to Fig. 7, but illustrating the magnetic valve energized and the valve open; Fig. 9 is an enlarged side elevational view of the magnetic valve of my invention showing the magnet de-energized and the valve closed, and illustrating in section the manner of mounting the armature for rockable movement; Fig. 10 is a perspective view of the mounting bracket for the magnetic valve system of my invention, showing particularly the comb-like arrangement of the supporting plate for the several adjacent electromagnets, which is so shaped that the individual magnetic lines for each of the magnetic systems are maintained substantially independent; Fig. 11 is a perspective View of the bearing rod for the several rockable armatures of the multiple valve system; Fig. 12 is a perspective view of the tongue which is secured to the end of the magnetic core for connection of the springs for tensioning each of the rockable armatures; Fig. 13 is a perspective view of the resilient strip employed on each of the magnetic armatures for tensioning the armatures with respect to the bearing rod; and Fig. 14 is a perspective view of the rockable armature which controls the functioning of the valve.

My invention contemplates a magnetic valve system for organs operative either under vacuum or pressure control in which a multiplicity of electric valve actions may be assembled in a relatively small space and independently adjusted for proper mechanical tension, and independently operated under selective control of various keys. The bracket mounting for the electric valve actions is so constructed that the magnetic paths through the magnetic actuators for each of the adjacent valves are maintained separate and independent. Each magnetic armature is provided with a mounting groove and a resilient retaining member arranged to coact with a bearing rod for insuring precision rocking movement of each magnetic armature as the associated operating magnet is energized or deenergized. The core member for each magnetic system is provided with a tongue projecting therefrom which provides a connecting means for a spring which extends to the resilient strip associated with the armature. The bearing rod around which each of the armature members pivots, is welded to the supporting bracket at opposite ends thereof and at intermediate positions along the bracket. Preliminary to such welding action the bearing rod is secured in position by means of clamping rivets which pass through the bracket. The assembly of the valve system is extremely simple in that it is only necessary to spread the resilient strip away from the armature sufficiently to permit the groove in the armature to be engaged upon one side of the bearing rod, while the resilient strip engages the opposite side of the bearing rod. The spring which extends from the end of the resilient strip is connected at its opposite ends to the tongue which is secured to the end of the core of the operating magnet. This tongue is spot-welded t the end of the magnetic core and at no time establishes connection with, or is mounted upon, the bracket per se. tion of the electric valve action of my invention will be more fully understood by detailed reference to the drawings. 7

Referring to Fig. 1 of the drawings, reference character I indicates the pressure chamber having ports 2 therein leading to the reed pressure box 3, having an outlet indicated at 4. The reed is indicated at 5, mounted at one end on the reed supporting frame 6. As represented in Fig. 2, the several reed pressure boxes 3 are partitioned one from the other for the independent passage of air therethrough under control of the electric valve action. It will be understood that the electric valve action of my invem tion may be used for both vacuum and pressure arrangements, as in the usual pipe organ system, and that the illustration of my invention in association with a reed system is merely for the purpose of illustrating one application of my invention.

The bracket for mounting the several electromagnets is represented at 1, secured by suitable means 8 to the wall of the pressure chamber The bracket 1 is provided with apertures 9 therein through which a suitable number of securing means 8 may be passed. Perforations Ill are struck out of the material forming the brackets 1 and grooves I2 are provided in the material of bracket 1 through which bearing rod l| extends. Bearing rod H is spot-welded at opposite ends l4 and I5 in the aligned grooves l2. The bearing rod I may also be spot-welded to the material of bracket 1 intermediate the ends I4 and I5. Preparatory to the spot-welding operation the bearing rod II is retained in position in the aligned grooves |2 by means of tubular rivets l6 which extend through apertures I60, in brackets 1 and secure clamping members l1 over the bearing rod After the bearing rod II is thus secured in position it may be spot-welded to the bracket at the ends |4--|5 and also in intermediate positions l8, I9, 20, 2|

and 22.

The bearing rod |l,' across the perforations I0 is now ready'to receive the several rockable armature members which control the electric valve action. The armature is formed from magnetic material shaped as shown at 23 having a groove 24 adjacent one end, and angularly disposed as represented at 25 adjacent the opposite end. The armature is perforated at 26 to provide means for securing the valve to the armature. A leaf spring 21 is secured at one end adjacent the armature with aperture 28 in leaf spring 21 in registry with aperture 26 in armature 23. The spring 21 has its opposite end displaced toward the groove 24 in armature 23 to provide a yieldable gripping face operative against the bearing rod H. An

The mechanical construcextending transversely tending from core 31.

aperture 30 is provided in the projecting resilient end of the leaf spring 21.

The armature 23 and its associated leaf spring 21 carries the plate of insulation material 3|, through which the clamping tubular rivet 32 passes. Tubular rivet 32 clamps the armature 23, resilient leaf spring 21 and plate of insulation material 3| in superimposed position, A resilient pad member 33 is secured over the head of the tubular rivet 32 and over the plate of insulation material 3|. The pad 33 supports plate 34 and the facing portion of valve gasket 35 which contacts the peripheral edge of port 2 for closing the valve and providing one of the limiting abutments for the movement of armature 23. The movement of armature 23 in the opposite direction is limited by abutment of the armature with stop 36 carried by the control magnet spool head.

The control magnet comprises the magnetic core 31 which is secured in aperture 38 in magnetic bracket 1. Core 31 is welded within aperture 38 in magnetic bracket 1 and projects therefrom. Spool heads 39 are provided adjacent opposite ends of core 31 and intermediate these spool heads the operating winding 4| is arranged. The operating winding 4| is suitably insulated by a wrapping of insulation material to which extends about the magnetic winding 4|. One of the spool heads 39'has a perforated ear 48 extending therefrom with a girdle or band of solder or fusable metal 49 thereon to provide a terminal for the end of the operating winding 4|. The perforation in ear 48 is shown at 48a forming a securing means for the connecting wire which connects the winding in the circuit. The other end of the operating winding 4| is grounded to the core 31, as indicated at 5B. Circuits to the several electromagnets are thus completed by grounding to bracket 1 on the one side and by connection of individual wires to the solder girdles or bands 49 on the other side.

The bracket or tongue 42 which forms the connecting means for the coil spring 45 that tensions the movable armature, is welded to the end of core 31 and has a projecting end 43 ex- Coil spring 45 connects between the projecting end 43 of tongue 42 and the apertured end 30 of leaf spring 21.

The core 31 is suitably shaped at the end 41 to coact with th angularly disposed end 25 of rockable armature 23 to insure maximum utilization of th magnetic lines of force which extend around the magnetic circuit established through magnetic core 31, magnetic bracket 1, magnetic armature 23 and the shaped end 25 thereof. As before noted the magnetic bracket 1 is slotted at 46 intermediate each of the portion of the bracket which are apertured at 38 so that the magnetic lines of force which thread the portions of the bracket 1 are maintained substantially independent and confined to substantially separate paths for controlling the rapid and various functioning of the several valves within a small area.

It will be understood that the electric valve action of my invention may be employed as a single unit or may be arranged in th multiple coacting units illustrated herein. The construction shown has been found to be very ractical for manufacture and production and successful in operation. However, although I have described the preferred embodiment of my invention, I realize that modifications may be made and I intend no limitations upon my invention other than may be imposed by the scop of th appended claims.
