-ELECTROMAGNETIC VALVE;

Specification of Letters'latenta Patented Jan. r7,1913.

To all lwhom, t may concern.'

Beit known that I, HARRYQGEISSINGER, a citizen of the United States, residing at New York, Ain the county of New York and State of New York, have invented new and useful Improvements in Electromagnetic Valves, of which the following is a specification.

My invention relates' to electro-magnetically operated devices and more particularly to electro-magnetic valves, which are adapted to control the flow of steam or hot water to radiators. It is essential in valves' of this character that the electric actuating Acoils shall be completely 'isolated from the steam or water andthat the movable ,parts shall olperate with as little friction as possible for t e purposeof economy in the power re-` quired. It is also advisable to so arrange the valve that in case of any interruption in the electric service the valve shall be left in the olpen position and subject to manual contro It is the purpose of in invention to provide a valve which shal possess all of the above features. The valve stemis free to move with practically no friction since I avoid the use of any stulin boxes or packing. Ihave, however, provi edaconstruction which involves no loose or rattling joints and permits of noiseless operation. My valve is ada ted to bereadily adjusted to standard va ve bodies.

the casing and secured in Other advantages will be apparent froml the following description in connection lwith the accompanying drawings which rep resent in vertical cross-section one embodiment thereof.

' The valve-casing 1, is provided with the' usual seat 2,- upon which the packing 3 ofk the valve disk 4.- is adapted to rest when lowered into. the closed position, the valve being normally spring-held in the open position.

The electrosmagpe'tic actuating mecha-- nism com rises a ase member 6, provided with a tu ular extension 7, screwing into sition by a locknut 8 and packing 9.v he magnetic shell 12 inclosing the energizin coil13, is provided with a depending ho low core 14 and has an annular flange 15 fitting over the -flanged edge of the base. Wit-hin and proabove the hollow magnet coreV is iwmg a non-,magnetic tubular separator 16, closed at its upper end and having its lower flaring annular base 17 bolted to the magnetic base member 6, the joint being made steam tight by means of a gasket 18. This tube 16 forms the guide for the plunger 20 of the magnet and separates it magnetically from the core 14. A nut 22, screwing upon the upper projecting end, of the separator tube, bears up'on the top lof the magnet shell l2 and clamps it firmly upon the base 6.

The plunger rests upon the upper end of the hol ow valve stem 23, which bears upon the valve disk 4. A tubular guide and support 25 for the: valve and valve-stem is threaded within the tubular extension 7. A spring 27 having its lower end secured to the valve disk l1,-passes through the stem 23 and is sus ended from a pin-28, which passes through t e slotted upper end of the'stem and rests upon the top of the tubular guide 25. The spring yieldingly holds the valve in raised or open position and sustains the weight of the valve stem and plunger.

The operation of this valve willbe understood from the foregoin description. Normally the valve is hel in the,"0pen or raised positionV as illustrated. When the coil 13 is energized, the magnetic flux lines generated are caused to pass downwardly through the shell 12, flowing throu h the base 6 and converging in the centra posi- Ation where they jumpV across the intervening space to the plunger, completing 'the magnetic circuit by threading the gaps constituted by the non-magnetic` separator'l and enterin the core 14. It is evidentthat the ma etic ilux` will produce opposite .magnetic oles 10,101, in the lower plunger face and t e opposite portion of the base andv that the magnetic tension will' draw the plunger downwardly, forcing the valve disk against its seat in opposition to the force of the Huid-pressure 'and the spring 27. yThe parts are so adjusted that the lower portion of the plungerV will oo cu y the dot-ted line position and be held slig tly out ot contact' with thebase in order that there maybe no tendency to adhere when the coil. is denerized. This adjustmentis effected Vby raising or lowering the base member 6 in the valve casing. `The tension of the s ring 27 may 'be altered lby the'hei ht of tllie' guide tube 25 within the tubular' ase lextension 7. The electric connection with the coil may be made by means of binding posts 29,'passing through the shell said posts being inclosed in a protective housing if desired. As soon as the coil 13 is denergized, the spring 27 .will

trol of a thermostat, the electric energy will' only be expended when it is necessary to close the valve due to the use of temperature above normal. It will be observed also that in the event of an interruption of the -electric service, the valve will be left in the open position and may then be manually controlled. For the `purpose of closing the valve manually I provide a screw plug 31 in the top of the separator tube which may be forced down upon the plunger until the valve is seated. When the screw plug is Iin the normal position, as shown,'the packing 32 insures a steam-tight oint.

Engineers and others skilled in the art will appreciate the important advantages of this invention. I have provided a valve especially adapted for radiators which is exceedingly compact, practically noiseless, and in which `the electric actuating coil is completely isolated, yet leaving the valve-piston or stem free to move without any friction due to the restraint of packing. The base of the magnetic shell inclosing the actuating coil screws directly into the valve-casing and may be adjusted to any standard valves. By enlarging the lower end of the plunger and producing an attracting magnetic pole of corresponding area in the base ofthe magnetic shell, a very strong pull is produced upon the plunger.

It will be evident that various changes may be made in the st-ructure of parts which have been illustrated for the purpose of showing an embodiment of my invention without departing from the spirit thereof or the scope of my claims, which are 1. An electromagnetic valve comprising a valve casin having a valve seat, a valve disk, yielda le means for normally holding said disk in open position, means for adjusting the tension of said yieldable means a magnetic shell having a depending tubular neck threaded to said casing whereby said magnetic shell may be adjusted toward or from t-he casing, an energizing coil within the shell, and a plunger reciprocable within v`said coil having a stem passing through said neck to actuate said valve disk, said plunger having an enlarged the base of the shell to form opposite magnetic poles when said coil is energized, whereby the plunger is operated.V

2. An electromagnetic valve comprising a valve casing having a valve seat, a magnetic shell having a depending tubular neck supported upon said casing, anenergizing coil within said shell, a valve-disk having a ase coperating with stem projecting through said tubular neck, a
