BALANCE'D ROTARY VALVE.
SPECIFICATION forming partrof Letters Patent No. 264,525, dated September. 19, 1882. Application mea Ju1y24,1se2. (No model.)
To all whom Muay consom.-
Be it known that I, JOHN S. GLENN, of Ghicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Balanced Rotary Valves 5 and I Vdo hereby declare that the following is a full,
clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The nature of my invention relates to valves for steam or hydraulic engines of the kind described in Letters Patent No. 200,388, which were granted to me on February 191878; and it is my object to construct such a valve that is more readily adapted for a three-way cock,
or for steam-engines having a separate valve for each port, and in which the pressure and wearin g surface is counterbalanced from opposite sides, so as to be moved with very little friction, and that its surface will Wear even.
Therefore my invention consists in the peculiar construction and arrangement of the valve and casin g, and in the construction of the stuffing-box, all as more fully will be hereinafter described and specically claimed.
In the accom pany-ing drawings, Figure l rep-Y ,callyopposite screw-necks, ct and b, a screw` neck, c, that forms a continuation of the small end of the bore for the valve, and with a screwthreaded opening, d, for connecting the stuff in g-box. The screw-neck a, by a port, e, communicates with thespace above the valve-seat, and the screw-neck b communicates through two quarter-circular channels, f and f', with the two ports g and g4, that are cut through the valve-seat shell at its diametrically-opposite sides.V Intermediate of and rectangular with these ports g and g', and of equal size therewith, are formed two cavities, h and 71,', which are also diametrically opposite.
B is the valve, which is turned conically to makel a tight fit with the conical bore of the casing. This'valve has four ports, t' t and jj,
rim of valve B with stem o. This stem o has a collar, n, and above such collar the stem is conicalf The'cylindrical portion ot' the stem 4is screw-threaded for securing the packingsleeve D by a jam-nut,E, and the extremity of such stem is reduced in diameter for attaching a hand-wheel or operating-lever.
F is the stuiing-box, which is screwed intothe opening d of casing A. This stuffing-box is bored cylindrical in the bottom for admitting the collar n, and is bored out in its top end for admitting the packing-sleeve E, and
theintermediate portion is bored out conical to correspond with the conical portion p of the valve-stem. The conical chamberbetween collar u and sleeve E is filled with packing, that Four curvedarms, m, form the connection between the upper is tightened therein by screwing down the sleeve E, which packing, inpressing against the conical surfaces of the stuffing-box and valve-stem, will push the valve down and hold it in its seat, and will thus provide an elastic shoulder for such valve upwardly, while its lower edgeisbroughtto bearagainstashoulder, t", above screw-neck c, that will prevent such valve ,from hein g forced too tight in its seat. The collar n of valve-stem o is to be of a diameter to provide sufticientarea for counteracting the downward pressure upon the valve B, which pressure should be just enough and not -more than to hold such valve to its seat.
When applying the valve as a three-way cock the screw-neck b ofthe casing is to conp neet with the supply-pipe, While the screwnecks a and c are to be connected with the two branch pipes, either one of which can be made to communicate with neck b by turning the valve B so as to bring either its ports t' orj in IOO line with ports g and g of the casing, or the supply may be shut oli' entirely by turning the valve half-Way, whereby all the ports are being,r closed.
For steam-engines the neck a of casing A is Jro form part of the steam-cylinder port. Neck b is to communicate with the steamchest or steam-supply pipe and neck c with the exhaustpipe; and when thus applied the valvecasings may be cast solid with the-steam-cylinder, one to each end.
As will be seen from the above description, this valve is perfectly balanced around its circumferential face, while its end pressure can be regulated by the size of collar a. The circumferential Wearing-surfaces are equalized by the cavities 7L and h, which will also assist in lubricatingsuchsurfacesnniformly. Thestutt'- ing-box, by its peculiar construction, Will hold the valve to its seat by the interposed elastic packing, thus assisting an easy movement of such valve; and the entire arrangement ofthe alve is such that it Will answer equally Well for steam, air, or Water, and offers equal advantages as a rotary or oscillating,` valve.
l. 'Ilie conical valve B, having ports t' z' and j j and U-shaped partition K, in combination with the casing A, having screw-neck a, that communicates through channel e with portsjj ot the valve, having screw-neck b, that is connected with the diametrically-opposite ports gg by channelsff, and screw-neck c, thatcommunicates with the ports i t' of the valve, all substantially as and for the purpose set forth.
2. lThe conical valve B, having ports i and j j and U-shaped partition K, in combination ivith the casing A, having screw-neck a, with channel c, screw-neck b, with channelsff, and diam etrically-opposite ports g g and intermediate cavities, h h, and screw-neck a, all constructed and arranged to operate substantially as and for the purpose set forth.
3. The combination, with the conical valve B, havinga partially-conicalstem,o,witl1 collar a and screw-sleeve D, of the casing A, having conical stuffing-box F, the Whole being constructed and arranged substantially as and for the purpose described and shown. f
4. The casingA, that forms the conical valveseat and has screw-neck a., with channel c, screw-neck b, with channelstyf, and diametrically-opposite ports gg', intermediate cavities, 7L h', shoulder i", screw-neck c, and conical stufiing-box F, in combination with the conical valve B, having ports i i andjj, partition K, arms m, and stein o, with collar a, adjustable packing-sleeve D, andjam-nut E, the whole being constructed and arranged to operate substantially as and for the purpose shown and specified.
In testimony that I claim the foregoing as my Pinvention I aftix my signature in presence of tivo Witnesses.
