VALVE.
Specification of Letters Patent.
Application filed May 12, 1914. Serial No. 837,975.
To all whom it may concern:
Be it known that I, THOMAS K. LEMON, a citizen of the United States of America, residing at Arverne, Queens county, New York, have invented certain new and useful Improvements in Valves, of which the following is a specification.
My invention relates to valves and particularly to radiator valves for use in water heating systems and analogous situations and it consists in the devices whereby I am enabled to readily and yet securely set the valve so as to regulate the flow of the medium it is intended to control be that Water, steam or vapor.
Figure l is a side view of a complete valve embodying my invention. Fig. 2 is a vertical sectional view of said valve. Fig. 3 is a cross-sectional View on line 3-3 of Fig. 2. Fig. 4 is a cross-sectional view on line 44 of Fig. 2. Fig. 5 is a perspective view of a form of stop which I employ.
1 represents the casing of the valve which is of ordinary construction with an inlet 2% and an outlet 23, except that the bonnet 2 is provided with a series of apertures 3, preferably constructed in a projecting flange 4.
The stem 5 may have the usual stuffingbox 6 and handle 7, but for the valve proper, I prefer to employ a cylindrical shell 8, secured to or formed integral with the stem 5 and fitting snugly into the cavity in the body of the casing 1. This cylindrical shell has a cut apertured in the side somewhat preferably triangular in outline,'the side 22 of the triangle placed horizontally as shown in Fig. 2, the purpose being that as the shell 8 is turned around the aperture may register with the outlet in the casing to a greater or less degree (according to which way the handle is turned) and thereby permit" a greater or smaller quantity of the inclosed medium to pass through, and the purpose of locating one side horizontally and toward the upper end of shell 8, is to keep the larger part of the opening always at the top, since better results are thereby attained.
9 is an adjustable stop, which I call a locking arm. It has a projection or finger 10 adapted to enter any one of the apertures 3 in the casing 1, and, for convenience, it is bent at right angles to the axis of the stem and apertured at 11 to permit the passage of the stem therethrough, that being a convenlent way of securing it from acciden- Patented Mar. 9, 1915.
tal misplacement. Then I provide another adjustable stop 12, which I call a stem stop. It is preferably in the form of a cylinder slotted as at l t, for a considerable portion of its lengthenough to accommodate lock ing arm 9and substantially closed at one end by a cap 15, provided with an aperture 16 for the passage of the stem 5, and a series of apertures 17 to receive lockingpins 18 which project from the button 19 through apertures 17 to and into recesses 20 in the handle 7, which is usually held in place by a screw 21 passing through it and into the stem 5.
Many times it is desirable that a valve be so arranged that it may be easily opened a given distance, but will be stopped from further opening. For instance, in heating systems, it sometimes happens that one or perhaps more of the radiators will not function because some other radiator takes too I much of the circulation, but if the valve of that other radiator be choked to a proper degree, the other radiator will operate satisfactorily. Sometimes several radiators in a system will need such regulation, sometimes only one. Such regulation is best secured by some arrangement which will permit of the operating of the valve in the dark or by some one who knows but enough of the science to turn a handle, and to secure some such arrangement without making a special valve for each radiator, it is necessary to provide some form of stop which shall automatically arrest the turning of the stem when the selected and predetermined degree of opening shall have been reached. These degrees are many and are to be selected with considerable nicety by an expert in heating in order to obtain the best results and to provide him with one instrument capable of being adjusted at a considerable number of different degrees of exposure so that the regulation may be close and yet may be accomplished without providing a different variety of valve for each radiator is my object. The one shown may be adjusted at more than 50 different degrees of opening as will be manifest.
The expert first determines, usually by experiment, what degrees of opening for the on till the pins 18 protrude through some of.
the holes 17 in the head or cap piece 15. If the adjustment is so close that the holes 17 will not register with said pins, the expert draws the casing stop or locking arm 9 back and inserts its finger in another aperture in the casing, brings the stem stop to engage ment and presses it down till the pins project through the appropriate hole whereupon he replaces the handle and secures it by turning home the screw. Having thus adjusted the two stops, he may shut olf the.
valve altogether by reversing the handle. Thereafter, when that valve is opened, the stem may be turned till the stem stop 12 (the, edge of the slot in cylinder 12) comes in contact with the casing stop or locking arm 9 when further progress will be arrested, but that arrest will always take place at the particular degree of opening theretofore selected as the very best one for the system which includes it, and as is manifest, that correct opening can be done by anyone, even in the dark, all that is necessary being that the handle shall be turned as far as the stops permit.
With the arrangement shown, there may be as many different adjustments for each placing of the casing stop or locking arm 9 as there are openings in cap 15 for the ins, so that the full number of adjustments possible is the number which may be accomplished by placing difierent holes in the cap 15 over pins 18 multiplied by the number of holes 3 inthe casing provided for the locking bar finger. This gives a greater range than would be possible, were the adjustments to be made at either of the places mentioned instead of by the combination of two different adjustable stops.
No especial width is required for the sleeve stop. The cap should preferably accommodate a number of apertures but the part extending therefrom to engagement with the casing stop or locking arm 9 may be only wide enough to give suificient strength. The greater width shown is merely for the purpose of presenting a neater finish.
Copies of this patent may be obtained for 1. A valve composed of a casing, with an inlet and an outlet with a full passage way, a plug therein provided with a stem and a through way increasingin size in a lateral.
direction, but with its upper wall substantially horizontal, the upper part of the through way being adapted to register with the full way of the outlet, substantially as.
set forth.
2. A regulating valve, composed of a casing, a stem, a plug, an inlet, an outlet, an;
adjustable casing stop, openings in the casing to receive said stop, an adjustable stem stop, means for securing it to the stem, a series of openings for the adjustable placing of the said means,: all combined substantially as set forth;
3. A regulating valvecomposed of a casing, a stem and a plug, an inlet and outlet, an adjustable stem stop provided with a cap pierced with a series of openings, a handle, a button fitted to the stem and provided with pins adapted to register with the openings in said cap and an extension projecting toward the casing, which is also provided with a series of stop engaging openings, a casing stop swiveled on the stem and pro vided with a projection adapted to engage either of the casing openings and arranged as described to cooperate with the stem stop, all substantially as set forth.
4. A regulating valve, composed of a casing, with an inlet, an'outlet and a series of stop engaging openings, a stem provided with a shell with a graduated opening adapted to register with a passage through the casing, a locking arm swiveled on the movably holding said handle to said sleeve,
all substantially asset forth;
In testimony whereof, I have signed myv name to this specification in the presence of two subscribing witnesses, this 11th day of May 1914;.
