-To all (whom t may concern:
able others skilledin the art tol which it.
appertains to make and use the same.
This invention relates to improvements iny joint expanding rings. l
One object of the invention'yis to provide means whereby one member of a threaded yjoint will berautomatically expanded when screwed into engagement with the adjoining member thereby forming an absolutely fluid tight connection between'said` members.
Another object is to providean expanding `device of this' `charat'zter which will be simple andhinexpensive in construction, etlicient and vreliable. in voperationiand which when applied to valve seats,-pipe couplings or other joints will form a positively tl'uid tight con- 4nection between the saine without requiring i excessive .force to be applied to'eithe'r niemrber of the oint when making the connection or .without necessitating an accurate fit between the threaded parts of tliemembers.4
lVith these and other obJects 1n view, the invention consists of certain novel tentures of'censtruction and the combination and ar rangement of parts as will be more fully described a'ld,claimed. f l 1 .In the accompanying drawings: Figure 1 is a vertical section through a valve casing showing our ,improved expanding ring applied to the-removable valve seat of the casing 'for forming an absolutely fluid tight joint-between the engaging parts of the seat and the easing. Fig. -2 .is an enlarged sectional view through a valve easing showing the application of our improvedrinfr for expandiner the ,valve seat therein, saida seat being in a reverse position from that occupied by the seat shown in Fig. 1; Fig. 3' is an end view of a valve seat constructed to' receive our improved expandingrlng; Fifi.`
l is a longitudinal section through the connected ends of two sections of pipe showing our improved 'expanding ring applied to the joint thereof. i
Referring more particularly to Fig. 1 of4 the drawings, 1 denotes the casing of a re ciprocating valve and 2 denotes the valve ywhich.isslidably mounted in the casing.
These parts may be ot' the usual or any suitable lconstruction. The valve `casing 1 is provided with a removable valve seat 3 and at the point where said valve seat is engaged therewith, said casing is threaded in, the usual manner." At the end ofthe threaded portion of the valve casing the passage `ther"ethrou'gh vis reduced to form an annular interior shoulder 4J The valve seat 3 Yis in the form of a ring having its outer surface threaded for engagement with the threaded portion of the valve casingto which the seat is applied Vand the outer portion of the valve seat is chamfered or flared outwardly toward its outer end as shown at 5 to provide an annular inclined surface 'adapted to be ybrought into engagement with our improved exp-.hiding ring which is engaged with the shoulder 4 in the valve casing. The upper surliice of the expanding ring 6 is tapered as at 7 to eoin'eidewith the 'chanifered surface 5 of the valve seatwhen the vlatter is screwed down in position in the valve casing.
`In' applying the seat the expanding ring is first placed in position on the shoulder i after which the seat is screwed downwardly by hand, until the chamfered portion thereof comes into engagement with the tapered outer' surface of the expanding' ring after which a wrench may be applied to the wrench receiving lugs S of the valve seat ,and the ylatter screwed inwardly to a greater extent which will cause the tapered surface of the expanding ring to force or expand the engaging portions "of the valve seat out--y wardly into absolutely fluid .tight engagementwith the threaded portion of the valve casing. y In Fig.l 2 of the drawings is shown a valve seat 9 constructed inv the same manner as the valve seat 3 shown in Fig. 1, said valve seat 9 being arranged in the' casing. 10 in a 're- "verse position from that occupied by the -valve seat 3 shown in Fig: l. vThe valve seat 9 shown in Fig. 2 is provided .with an expanding ring 11 constructed and arranged in thesame manner'asthe expanding ring 6 hereinbefore described and saidvalve ring operates in the same lmanner tofexpand the threadedportio-n of the valve seat'into engagement with the threads of the valve .casing for forming 'an' absolutely fluid-.tight joint between these parts init-he same manner as described -in connection with the -corresponding parts shown in Fig. 1.
lIn Fig. i of the drawings is shown the engaging ends of two sections of pipe which are connectedby a threaded joint, said joint vbeing expanded by one of our improved expanding rings 12 which is applied tothe joint in any suitable manner. In the .present instance the end of one of thepipe sections is reduced and threaded as -at land said threaded end is screwed into the interiorly threaded end of the adjoining section as shown. In the interior-ly threaded section is formed an angular inwardly, extending flange 1 4 which provides a stop'shoulder for our improved ringy 12. which 'is engaged therewith as sho-Wn. The reduced exteriorly threaded end of the opposing pipe section is chamfered on its inner side to form an inclined or tapered ring engaging. surface,f
which when the end of this pipe section 1s screwed intonthe threaded end of the opposing section will engage the tapered surface of 'the expanding ring which will expand or Jforce the chaint'ered end of the pipe out-' the machining of thehthread's to provide an accurate and tight lit between the engaging portions of a joint is obviated as the expan-l sion of one of. the engaging parts by our 11nproved expanding ring will overcome any slight inaccuracies or loose tit-ting 'of the 1 parts Aand will bring the threaded surfaces into' an absolutely fluid tight engagement.
rIhe use of our improved expanding ring also permi'ts'the parte. l of the yjointiiso :he
brought together into Huid-tight engagement scribed. l j y In constructingv our improved ring the corners at the smaller end thereof 'are pref-f e'rably slightly rounded as shown`to prevent' with much less ,force than is requiredy in thev 4usual connectio'n of" the 'partshereinv deshearing of the tapered surfaces v.with ,which l they are engaged.
f From the foregoing ldescription taken in connection With the accompanying *draw ings, the construction and operation of the 'invention will be readily understood without vrequiring a more extended explanation.'
Various changes in the form, ,pro'prtion and the 'minorV details of 'construction may" be'resorted to without departing from lthe principle or sacricing any yont theadvantages of the invention as claimed.' y
Having thus described our'invetion, what. We claim is: i j i In an expanding devicefor valve' seats,l
the combination with a valve Casin havlmg therein a stop shoulder and a threa ed valve receiving portion, of4 an' exteriorl'y threaded valve seat adapted to be screwed .into en gagement with. the threaded portion of the valve casing and having its threaded, end
chamfered on its inner s1irfacejfanvexpandd ing ring adapted to be engaged with the stop whereby when the. latter is screwed .into 'the casing, the 'tapered surface ofthe expanding ring will expand the 'threadedend/of 'the valve seatintc absolutely fluid-'tight'engage-` ment with the threaded. Surface-ofthevalve casing. y j
In testimony' x'vhereof;y we have hereunto 'set our hands in 4presence' oftwosubscribing witnesses. I
