Paten d, J n-.1649?- Be it known that I, JARARD W. Lv'r rorf, a-citizen of the United States,- residing. at. Franklin, in the county of Southampton; and State ofVi'rginia, have inventednew and useful Improvements? in Bottom Blow- Valves, of which the'following is'a specifi-' cation. f r
'The resent invention relates to valves; and in 1ts present embodiment is shown in connection with that type of valve known particularl'ytor use at the bottom or leg of other apparatus if desired. J a
The object of the invention is to p ovlde. a valve of such construction that the valve less likely tobe attacked and worn either cessity for the renewal-of the seatand valve will not be so .f requent,'its life-will be pro-- longed; and its operativerless willbeflmaintained. Furthermore the construction is their roper relation for a long period withtightening pressure upon the valve stem to same time the partsgmay be maintained in a perfectly tight condition. Again the con struction' is such [that the. valve will be stopped at the two extremes of its movement (0pen and closed) 'positively, and the arrangement of valve stops-ls'such that the arts can not be assembled by careless or the proper functioning-jot the valve. I,
In the drawings herewith "I have illustrated-one embodiment of my'invention 'and that the best now known to me, but a'sthis disclosure is simpl illustrative, and 'inf no." sense restrictive ozhmy invention, it is to ehanical variations in structure'without de from the invention. a p g In t e drawings-Figurel is alongitudinal sectional view of a'valve constructed in accordance with my invention. }Fig..2 is av upper part ofthe valve casingbeing out Application filed Deceihiiet12,.191of Serial m. 596,876.
' awa to better-illustrate the relation of the.
valve stem and the valve stops; -Fig 3 is a View looking into-the upper member of the: 7 vvalve-cas n'g to show the arrangement of stops. a. I v
' Referring to the drawings by numerals; like numbers indicating likeparts inf/the to several views, '2,deno testhe lower section "ormember f the valve casingjwhichmay be of any desirable form, and is provided with" an outlet nipple The said casing member.
2- has' on its'upper surface a s'eatjwhich re.- ceives the seat member 4 ofthe .valve', which fits snugly a flanged .seat formed in the upper casing member-7, this" valve seat-,4 being formed of brass'onother suitablealloy 1 so a's'to give a goodseat surface] .The valve is of the'rotary type 'as-shown, and the said" 7 valve seat is ported as atsgm rovide the necessary outletportsr and in or 'er'ithat the seat may be placed and maintainedi in its' proper position it is preferably secured .by
a dowel pinconnection 6,as shown in Fig:
1, where it will be seen that'ardowel-I p-inrises from the casingmemberQ; a n'd.,when
i the valve seat A: is dropped to place engages i a hole therein,- the pin of thisiioweh'connec- "'tion' 6 being shorter than the hole vin the valve seat 4 to receive\ it,v1 so lthat the-dowel ."pin will not interrupt the' surfacetofthe val'veseat 4, for'ifthe dowelfpinprojected' above or levelwiththe seat surfa'ceit' would,
if ofharderlnetal thanthe valve seat, wear the valve disk-during its movements-,and if D it was of the same or softer-metal-it would in time become spread b the action of thevalve isk, and would riv'eti the valve seat inith'e c'asin both of which conditions would beundsira le.
. The casing member supports the upper half of the valve casing 7 which is provided withan finlet'ni 18 8-, thiscasingmember -7 being: bolted-1n the usual mannerjto a lower casing'member 2; as shown, and preterably as appears from Figh -2 there: is a dowel connection 9 between-these. arts in order: that they may befalways maintained in their proper relation; ;-The said casing- ,member,7 has a st'uflingbox 10 for the valve stem which "s of any suitable or desired construction, the form shown here comprising a chamber through which the valve stem passes; a] packing surrounding thevalvef 1 ag r:
stem, and. a flanged packing ri11g11 above this packing, which packing ring isheld to its place by a cap ring 12. The packing ring 10 preferably slides freely' in the packing chamber of the stuffing box, sothat in assembling the parts it may be dropped in onto the packing, and the compressing of v the packing is accomplished by. forcing the,
-' pap ring 12 against this; freely sliding pack- 111g rin. v; 1
The valve stem 13gis provided at its lower end with-a .crosshead 14 which engagesloosely lugs 15 projecting from the valve I disk 16, this valve disk having ports 17 com- 15 plementary to the ports 5 in the valveseat 4 and the said valve disk 16 in the present design is intended to rotate through an angle of ninetydegrees injgoing from one os tion to another, that is from open position The said v o to closed position, or vice versa. 7
valve disk 16 is seated in an annular cav ty or depression formed in the upper easing member 7', audit will be apparent from Fig. "*lthat the valve seat 4 and valvedisk 16 will 5fbe held'in'snug operating relation when the casing members 2 and 7 are securedtogether oth'at no force need be exerted upon-the jialvej stem 13 to hold the disk to its seat, t iereby relieving the cap ring from the necessity' of holding the valve to its seat through the medium of the -valve stem 13.-
Furthermore the valve seat 4 and the-valve disk '16 are always firmly held together so opens or closes and danger of foreign matter,
getting between the valve surfaces fromthis sourceis small,,-as the parts are constantly wiping and sweeping the surfaces clear. 7
The valve stem 13 is provided, as has been stated, with a cross head 14, and just above this cross head is a stop lug 18 projecting radially from-the stem 13, and additionally I provide thestemll'b with a small flange 19 j which bears against the underside of'the upper casing7 and prevents upward move: ment. of the valve stem 13, anddisengage-1 i ment of the crosshead and valve disk lugs.-. The said step lug 18 plays between stops 20] formed on the under side of the top wall of theupper casing 7 and these stops are' preferably formed as shown as right angle projections diametrically opposed, andfi'having' their opposite walls at exactly'nii-ety degrees apart in either direction; With this construrtion it will be obvious that when the raise stem is rotated to throw the valve through its anlmlqr travel, thelstop mg 18 will wrm t a var e movement'of ninety de- 'fluid tight in contact with the valve seat, 'andmeans-forfastening together the two the valve closeagainst the valve seat and socketformedf in one of said members, means vfor preventing the rotationf ofsaid valve .grees ,'-and that thisistopping' of the valve will secured whether the stop lug 18 plays on 'oneside'E-or' the other of'the stops 20, so
that no=-'mat ter how'the stem 13 is dropped intothe valve casing a proper angular move- 73 ment will always be secured, and no danger of lapping or bridging thevalve is present.
,This is one of the important features'of' this .valve structure for the reason that the parts This will be clear from Fig. '3, for it will there'be seen that-with the valve stem'placed in the position shown in, full lines wlth its cross head in engagement with the lugs of the valve disk an. angular movement of ninety degrees will be. secured when the stop lugis thrownfrom one extreme to theother.
It will .be apparent if the valve'stem be a dropped in, in the position shown in'dotted lines that an; angular movement of ninety degrees in the same direction may also be secured.
