Penick, Houston, Tex. 3 Application October 16, 1943, Serial No.‘ ‘506,610 V2Claims. (01. 251-71)‘ _* This invention relates to a valve assembly. An object of the invention is to providean assembly of the character described embodying gageable with an external annular shoulder 12 on the bonnet and thev clamp nut_l0, has a threaded connection with the valve casing as a casing with a ?owway therethrough and hav clearly shown in Figures 1 and 2.1 ing a controlling assembly in the casing provided with a ?owway which may be brought into align ment with the ?owway- of the casing to provide Within the casing there is a cylindrical con trolling assembly including the cylindrical sleeve ; ; ' _ , valve I3 one end of which has the transverse bore I4 and the other end thereof has the'vlongie - an unobstructed channel for‘ the ?ow of ?uid through the‘ valve assembly; said controlling assembly'being movable to another position’ to close the ?owway through ‘the casing and being expansible with means to expand the same to tudinal inwardly tapering bore ‘l5 wherein there is ?tted a tapering expander I16. This‘. expander form ?uid tight seals, when the’ valve is closed, through and the‘ other end is’ internally and coarsely'threaded to receive the coarse ‘threads l8 of the valve stem, I9,‘ This stem extends fits snuglyin the ‘bore 15 and is formed hollow; One end of the expander has the ducts ‘H there-. to prevent leakage of the ?uid ?owing’ through the line into which the valve assembly is con nected. ' axially through the bonnet and‘ may be turned , by'any selected meansias by the'hand wheel 20. It fijsimounted-to swivel in the'bonn'et by _~me'ans of an external rib/f2!‘ thereon which rotates-"in insideannular groove 72 2‘ in the bonnet. -"Iihejrib Another object of the invention i-sto provide novel means for expanding the controlling as sembly. ‘ ‘ - ’ The invention also embodies a novel lubricat ing system for lubricating the movable parts. is'retain‘ed in-the groove 'by means of an'irisidé With the above and other'objects in view the gland 23 which is screwed into the bonnet against said rib. invention has particular relation to certain novel The expander I6 is mounted on a coil spring 24 features of construction, operation, and arrange ment of parts an example of which is given in 25 which is interposed between it and the bottom of - the bore l5 and is retained against detachment this speci?cation and illustrated in the accom panying drawings wherein: from the valve l3 by means of the retainer ring Figure 1 shows a side view of the valve assem-. 25 which is countersunk into the outer ends of bly, partly in section, showing the valve open. the expander and valve and which is welded to the latter as shown in Figures 1, 2 and 4. Ac Figure 2 shows a side view thereof taken at cordingly by turning the stem [9 the controlling right angles to the view shown in Figure 1 and assembly may be moved to open position as shown partly in section. . shown in Figure 1 or to closed position as shown Figure 3 shows a side elevation of the con trolling assembly. ' Figure 4 shows a side view of the valve assem in Figure 4. Opposite the bore I5 the valve [3 is provided 35 bly, partly in section, showing the valve closed. on one side with the longitudinal .slit 26 so that a Figure 5 shows a cross-sectional view taken on the line 5-—5 of Figure 4. Figure 6 shows a cross-sectional, fragmentary view taken on the line 6-5 of Figure 2. Referring now more particularly to the draw the valve will be expansible. This slit is at right angles to the axis of the bore M. The expander I5 is normally held in its outer position by means of a pin 21 mounted in the valve and Which projects into a socket 28 in the expander as shown more accurately in Figure .6. Its outer end extends out beyond the valve and'is ings wherein like numerals of reference designate the same parts in each of the ?gures the numeral l designates the valve casing which is, prefer ably substantially cylindrical in form. The cas ing has a ?owway 2 transversely therethrough ‘and may have the pipe connections 3, 3, around the ?owway for the connection of the sections 4, 4, of the line to the casing. One end B of the dovetailed and works in a vertical dovetail groove 29 in the inner wall of the casing and whose lower end is outwardly curved as shown in Fig ures 2 and 4. The pin has an external annular shoulder 30 and between said shoulder and the casing is closed and mounted on the other end " internal annular shoulder 3| of the valve there is a coil spring 32. thereof is a bonnet 1 whose inner end is formed with a ?ared seat 8 which ?ts over a correspond Upon movement of the valve from open posi- ' tion, shown in ‘Figure 1, to closed position, shown » ing tapering seat 9 of the valve casing. The in Figure 4, the expander and the valve will move bonnet is secured in place by a clamp nut [0 as a unit until the valve lands on the stop 33. which has an inwardly extending ?ange ll en 55 At the same time the pin 21 will have been with 2,406,099 s" drawn from the socket 28by the outwardly curved end is adapted to project into said socket and‘ end of the groove 29 assisted by the spring 32; 7 whose outer end extends out beyond the ‘valve ’ Upon further rotation of the stem the expander and is of a dovetailed shape; means connected With-the expander for moving the controlling as sembly to one position to align the bore with the passageway‘ and to another position to align the ' I 6 will be moved further into the bore I5 thus expanding the valve and causing it to fit very closely against the inside wall of the casing I around ?owway 2. a . .
