VALVE.

' Application inea June 17,

To all whomzt may concern Be it known that l, EDWIN B. LANE, a citi zen of the United States, and a resident of proof against derangement even by severe service conditions; the provision of a valve of the above general type having actuating devicesthat require avminimum amount of energy without sacrifice of lcertainty of operation; and the provision of ran electricallyoperated valve that can be manufactured at low cost and readily installed, and requiring only the momentary application of power to its coils to operate'the several parts of the mechanism. Other objects will bein part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplied in the structure hereinafter described and the scope of the application of which will be indicated in the following claims. v

ures 1, 2 and 3 of the accompanying drawings, there is shown at lthe base or casing of a valve which may be used to control the flow 0f fluid for any one of a variety of purposes, includingv the heating of a room or space or receptacle whose temperature is to be kept within predetermined limits. rThe fluid that is controlled by the valve may be the actual heating fluid or it' may be the fuelvfor the heating device; and the fluid may be liquid or gaseous. y v.

The valve comprises generally apair of actuating coils, one adapted for opening and Ythe other for closing the valve; the valve body per se; the valve stem; and parts actu* ated by the energizing of the coils for moving the valve stem in one direction or the other.

The frame 2 serves for a mounting for the coils 4 and 5, the former serving in the present instance to close the valve and the latter to open it. A spacing device 6, preferably non-magnetic, connects the two parts of the coil frame y2 at their lower extremities and is held inposition thereon by suitable retaining devices, such as the screws 7 `be replaced by shot or liquid or other convenient mass whose weight, exerted first at one end of the tube and then at the other, serves to hold the tube in osition against accidental derangement. ktops 101 limit the travel of the ball, and preferably seal the tube, to protect the ball from steam, gas,

-moisture or other deleterious matter.

Mounted at either end of the centrally pivn oted tube or runway 11 is a core 13 slidable within therespective solenoid coil 4, 5, and so related to the coil that energization of the coil causes the core to be pulled downwardly. 1n Figure 1 of the drawings the parts are shown the position they occupy after the energization of the closing` coil 4. vSuitable The -coilspare provided with sleeves or linings 8 nonmagnetic plugs or spacing devices 38 prevent the movable cores 13 from sticking at the lower end of their stroke by reason of residual magnetism. A mass 34 is provided on the same side of the runway 11 as the lever 14, and is or' such weight and distance from the pivot 19 of the runway, as to balance the weight of the movable part 15 of the valve, which is exerted upon the under sidey of the runway at the point of contact of the lever 14 therewith. This' makes the runway balanced except for the traveling mass 12, and ensures an equal certainty of operation regardless of the direction in which the mass `12 is traveling. f 1

The closing coil 4 and the opening coil 5 are preferablyloperated from a source of v through the valve-opening contact 40 energizes the valve-opening coil 5 from the battery 36 through the movable part 38 of the thermostat, valve-,opening contact'40 of the thermostat, right-hand binding post 28, right-hand vertically-movable cup 27 thereon, and runway 11, as will be clear 'from Figure 4. This causes the right-hand core 13 to be pulled downwardly. During the first part of the downward movement of the core, the contact at the parts 27-11 is maintainer because the cup; 27 has a limited range of vertical movement upon its binding post 28, the upper and lower limits; of this range being indicated by the relative positions of the right-hand and'let-hand cups 27 respectively. When, however', the core 13 has been drawn downwardly far enough to ensure the reversal. of inclination of the runway 11, and to insure the traveling off the mass 12 to the right-hand half of the runway, the cup 27 reaches the downward limit of'A its range of movement, whereupon the further downward travel of the runway l1 breaks the circuit between the cup and the runway and therebyv denergizes the coil 5. Thus the valve is operated with only a momentary application of power to the `coil 4 or 5, and the movement of thev valve stem 15y automatically opens the coil circuit and thereby minimizes the energy required for the operation of' the valve.l 1t will be noted, (i0

moreover, that this breaking ofthe circuit does not occur at the thermostat, so that the thermostat contacts,l f which are o'l'ten comparatively delicate, are not subjected to the arcs attendant upon the breaking of' the circuits. The binding posts 28 may be insulated from the frame or casing 22 in any suitable way, as by means of' the insulating bushings 26.

lWhen the valve is in its closed position, the passage of' Huid therethrough may be en- 'tirely stopped or only partly stopped. rilhe stem isfreely mounted in an adjustable sea-t 42 which is provided with threads engaging the lower part of the valve body 16 andy with threads of' smaller diameter engaging 'a flanged-l or shouldered lock nut 43 which rests against the lower portion of the valve body 16 and is protected from steam, gas, or other deleterious matter by a cap 45,

vwhich is illustrated as screw-threaded upon the valve body 16. By backing olf the lock nut 43, the adjustable seat 42 may be raised or lowered by turning it in its threads, and

may be secured in its, adjusted position by tightening against the lock nut. ln this manner the lowermost limit of travel of' the valve stem 15 may be adjusted as desired.`

In view of the above, it will bey seen that the several objects of the invention are achieved and other advantageous results attained.

As various possible embodiments might be made ot' the above invention and as various changes might be made in the embodiment above set fort-h, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. v
