VALVE.
To all'whom it may concern: I Be it known that I, FREDEBIOKO. BLAN- OHAHD, a citizen of the United States of Wayne and State of B Iichigan, have invented certain new and useful Improvements in Valves, of which the following is a specification, reference being had therein to the The invention relates to valves designed for installations in which there is only an occasional operation, and it is the object of the invention to obtaina' construction that is always operative either from closed or line 2-2 periods of time, there is danger that they will become inoperative, due either to the corrosion and adhesion of contacting surfaces, or
the lodgment of sediment, which prevents perfect seating. There is also danger of leakage through the packing material for the stem where the latter is operated after a long period of inaction. With my improvement these defects are avoided by a simple construction, as follows:
A is the valve casing which as shown is in the form of a cross having a bore B extending completely through one pair of aligned arms and transverse bores C and D extending through the other pair of'arms, but not intersecting each other or the firstmentioned bore. E'and F are bores extending at right angles from the bores C and D and arranged parallel with the boreB- G is a cap having a threaded engagement with the end of the casing towhich the" bores 13, vE and F extend, said cap formin a chain her for receiving a disk valve mounted on a stem I passing through the bore B. J is an enlarged 'or counterbored portion of the bore B, in which is arranged a packing gland formed of the member K sleeved upon the stem, the packing material L and a spring M which is arranged between the member K, and a collar N secured to the .fip c t of Letters Yatem- -Patcnted Aug. 29, 1922. Application filedbctober 25 1920. Serial No. 419,216.
stem. The collar forms a closure for the upper end of the counterbore and the reaction I "of the spring will exert pressureon the pack- Americ'a, residing at Detro1t,'1n the county of ing and also draw the disk H seat on the casing.- a The disk is provide towards a d with one or more apertures'O for registration with one or both of the bores E and F and to prevent adhesion between the disk and the seating surface, the latter, is restricted in area. Thus as shown in Figure 2, aboss P- s1irrounding the bore F forms aiseat for the valve and to hold thedisk' from tilting, bosses Q and R are arranged at angi'ilarly spaced'intervals. The total area of bearing surface is relatively small, and consequently, there 1s nodanger of adheslon between the a valve and its seat which cannot be easily broken by the turning of the stem.
lVith'the construction. as described, in use, the valve is connected with the passage C communicating with the inlet conduit and the passageD with the outlet. Thus the fluid pressure in the'inlet will act in con junction withthe spring M to hold thevalve disk to its seat, but this pressure is not suflicient to interfere with the operationof the valve. The passage 'E preferably communt cates with the chamber containing the valve intermediate the bearing points for the valve being thus in constant communication with said chamber regardless of the position of the valve. Thus the valve may remain stationary for any length of time and whenever there is occasion to use it either for shutting off or turning on the fluid, this may be successfully accomplished. In case of the deposit of sediment upon the disk, the clearance between the disk and the casing intermediate the bearing plugs or bosses will prevent said sediment from finding access to the seat.
The packing material L is preferably of an'indestructible and non-corrosive nature, such, for instance, as a mixture of stranded lead and graphite. The pressure of the spring J being constantly exerted on the I packing, it will maintain a leak-proof joint at all times.
What I claim as my invention is:
1. A valve comprising a casing havinginlet and outlet passages communicating with a common chamber, a rotary disk having an aperture for registration with one of said passages, a seat for said disk comprising an annular portion surrounding the passage controlled thereby, and angularly spaced'bearings for holding the disk in the plane of said seat, a stem for revolving said disk passing out from said casing, and means for resiliently holding said disk to its seat.
2. A valve comprising a casing of cross form, having inlet and outlet, passages in opposite arms thereof communicating with a common chamber in the stem of the cross, a rotary disk in said chamber having an aperture for registration with one of said passages, a shaft for rotating said disk passing through the stem of the cross, a seat for the disk including an annular portion surroundingthe passage controlled thereby, andangularly spaced portions for holding the disk in a fixedplane of rotation, a packing gland for said shaft, and a spring upon said shaft reacting to resiliently press upon said packing gland and to hold said diskto its seat.
3, A valve comprlsingacross-shaped casing having inlet and outlet passages in opposite arms thereof, respectively communicating with passages extending through the stem portion of the cross, a hollow cap for said stem portion forming a chamber with which said passages communicate, a rotary disk valve in SELlCl chamber having an aperture for .reigstration with one of said passages,a seat for said disk valve comprising; a raised portion, means in spaced relation to said seat for determiningthe plane of rotation of said disk, ashaft for rotating said disk passin through the stem portion ol the cross outsid e of said casing,a packing gland in thecounterbore surrounding said shait,a
collar on said shaft also engaging said counfltBlbOl'G, and a springsleeved on said shaft reacting upon said collar and packmg gland to resiliently press upon the packing and hold said disk to its seat.
, opposite arms thereof, and respectively com municating with downwardly extending passages 111 the stem portion of the cross, a hollow cap for the lower end of the cross forming a chamber with which saidpz'issages communicate, a rotary diskin said chamber hav ing a port for registration with one of said passages, a shaft for saiddisk passing out through the stem portion of the'cross, a seat for said disk including an annular portion surrounding the passage controlled thereby, an angularly spaccdbearingsfor holding the disk in a fixed plane, a packing gland in a counterbore in said casing surrounding said shaft, a collar on saidshaft for closing the outer end of said counterbore, and a spring sleeved on the shaft intermediate said collar and packing gland.
5. A valve comprising a casing having inlet and outlet passages communicating with a common chamber, arotary disk in said chamber having a port forregistration with one of said passages, a raised seat for said disk limited in area to a relatively small portion of the disk surface, means for holding said disk in the plane of the seat, and a stem for rotating said disk passingoutward "from the casing. I p p ln testimony whereof 1 affix my signature.
