it T a veneer. s'rEAM VALVE.

Application filed May 19, 1920. Serial no. 332,501. g

To all whom cit-may concern:

Be it known that l, ELMER O. COREY, a I citizen oi" the United States, and residing at Norwood, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Forcer Steam. Valves, of which the following specification is a full disclosure. j

This invention relates to a means for maintaining a certain spaced relation be tween an injector operating handle and the steanr inlet pipe of the injector, the provisionof such means heing'necessitated by the wearing or grinding of the valve operated by the said handle. 7

An object of the invention is to accomplish the above result by the use of a split, cylindrical cup-shaped coupling ring in which the valve stem is loosely held, and to so form the said coupling that its position within the valve may he reversed in a simple manner to compensate forthe wear of the'valve seat.

Otherobjects and certain advantages will appear in the description following, and special reference is made to the drawings, which form apart of this specification, in which:

Fig. 1, is a central vertical section through the steam inlet valve of one type of injector, showing my improved adjusting nut in position.

Fig. 2 is a fragmentary view, similar to Fig. 1, showing the reversed position of my improved adjusting nut,

Fig. 3 is a section on

line

3, 3, Fig. 1.

Fig. 1 is a perspective view of the two halves of the nut.

The numeral 1 designates generally the main casing of a double tube injector, 2 the steam inlet passage, 3 the steam inlet port, 4 the forcer steam tube, and 5 a disk-valve for controlling the port 4-. A conical valve 6, normally seated as at 6, is provided with a hinged extension 7, acting as a guide. At that side of the valve 6, opposite the extension 7 there is provided a hollow cylindrical extension or huh portion 8, interiorly threaded at 9, for the reception of a threaded plug 10, the same being provided with a central cylindrical bore 11 for the reception of the valve controlstem 12 of the valve 6. The extension 8 is chambered at 13, to receive a two-piece cylindrical, cup-shaped adjusting coupling or collar 14, which provides interior annular ribs 15 and 16, de fining

annular recesses

17 and 18.

' As shown in Fig. 1, the rib 16 engages. an annular recess 19, cut adjacent the end of the stem 12, and the head 20 rests in the re- .cess 17. This is the normal position of thev adjusting f coupling collar before the valve (Sand its valve seat 6 haveheen ground or 'worn. The valvestem 12 passes outwardly through a packing gland, in the casing 1. and 1s pivoted to the valve control lever 25, as at 26, the lower end ofthe lever 25 being pivoted to the extension 27, as at With the split collar 14L placedas shown in Fig. 1, and with the valve 6 in its closed position, the. spaced relation of the lever handle 25 relative to the stem inlet pipe 2*, is such that ample room is provided between the operators hand, which is grasping the lever, and the steam inlet pipe When, however, the valve and its seat have been ground, to a certain degree as represented by the parallel dot-and-dash lines in the drawing, the handleend 2. the lever 25 assumes the 13081131011 shown at 25",

by the dot-and-dash lines, and in such pcsi tion the 'handfof the operator strikes the steaminlet tube 2 To overcome the above diiiiculty, the position of the collar 14 is reversed, as shown in Fig. 2, the rib 15 engages the recess 19, the stem 12 is adjusted outwardly, and the spaced relation of the lever handle 25 restored, thus giving the desired hand room between said handle and inlet pipe 2.

The divided collar may be said to have a mortised connection with the end of the stem and is arranged to permit the collar to be transposed for extensibly connecting the stern within the valve. The collar, may if desired, he rigidly clamped within the socket of the valve between the end of the nut 10 and the shoulder of the valve bore as an annular end wall of the chamber or socket i 13.

threaded into the bore, the connection permitting a slight longitudinal movement of the stem within the valve 6, allowing the valve 5 to seat independently of the valve 6. The plug screw 34: is threaded into the bore of the valve 6 and bears against a shoulder at the end of the thread as a seat, for securely sealing the bore against leakage or escape of fluid through the bore from the opposite sides of the valve.

Having described my invention, I claim:

1. A valve having a cylindrical hub er:- tending from one side thereof, a valve stem provided with an. annularly grooved end en gaged into the hub of said valve, a divided collar having a plurality of internal annular ribs adapted to be alternately engaged into the groove ofsaid stein for extensibly connecting the stem to the valve, and nut engaged about the valve stem and threaded into said valve hub for confining the divided collar within the valve hub and thereby reznovably. connecting the stem to the valve.

2. A valve having a cylindrical hub extending from oneside thereof, a valve stem provided with a headed end engaged into the hub of said valve, a divided collar having means cooperating with the headed end of said stem ior extensibly connecting the stem to the valve, a nut engaged with said valve hub for confining the divided collar within the valve hub and removably connecting the stem to the valve.

3. A valve having a central socket in one side thereof, a valve stem havingan end ens gaged in said socket, a divided collar cooperatively engaged about said stem within the socket, and adapted to be set to transposed positions for extensibly connecting the stem to the valve, and means for confining the divided collar within the valve socket.

L. A valve having a central socket into one side thereof, a valve stem having an annularly grooved end engaged into said socket, a divided collar engaged over the end of said stem and cooperatively with the annular groove thereof, said collar being adapted to be set to transposed position for extensibly connecting the stem to the valve, and a nut concentric with the stem threaded into said socket "for removably confining the divided collar within the valve socket.

5. In compound valve for seating over two relatively aligned and lined ports, a first valve centrally bored to provide sockets for the ends of the stems projecting from opposite sides of said valve, a valve stem having an end engaged into said valve bore from one side of the valves, a divided collar cooperatively engaging about said stem within said bore for extensively connecting the sten to the valve, a nut threaded into said 'alve bore for confining the divided collar within the valve socket, and a second valve having a stem engaged and confined within the bore of said first valve from a side opposite to said first-named stem.

in witness whereof, hereunto subscribe my name, as attested by the two subscribing witnesses.
