VALVE.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed October 24, 1911. Serial No. 656.400%.

T 0 all whom it may concern:

Be it known that I, FRANKLIN M. PAT- TERSON, a citizen of the United States, and a resident'of Bayonne, Union county, State of New Jersey, have invented an Improvement in Valves, of which the following is a. specification.

The object of my invention is to provide a construction of a globe valve, in which the body portion shall be formed of stamped and drawn sheet steel, whereby great strength and lightness may be embodied.

My object is also to so construct the valve,

that its inlet and outlet may be adjusted to various positions in the same valve to adapt the valve for use under varying conditions.

In many uses of valves, it is necessary to have great strength without undesirable weight and my improvement exactly ful-' fils this requirement. In those cases, such as torpedo boats, where great lightness coupled with strength is essential, my invention is broadly applicable, and its adaptability is further enhanced in those cases in that the inlets and outlets of the valve may be relatively adjusted to suit the contracted spaces andpositions of the piping, resulting from the nature of the design required in boats of that character.

My invention consists, more particularly, in forming the body of the valve of three main parts, namely: a middle or diaphragm part in which the valve seat is formed or secured, said diaphragm part having its may be said to comprise, in a valve structure, a middle diaphragm portion of sheet metal, having its central part stamped and drawn so as to provide a valve seat in a plane oblique to the plane of the diaphragm, combined with two body portions respectively terminating in ports and said body -portions bolted or clamped to the diaphragm or middle portion. In the preferred form of the body portions, they are drawn from a piece of sheet metal so as to provide a flanged portion and a neck portion at an angle to the flange, said neck portion being combined with a flange secured to it, preferably by expanding the neck into the flange.

, My invention also comprehends details of construction which, together with the features above specified, will be better understoood by reference to the drawings, in which Figure 1 is a sectional elevation of a valve embodying my improvements; Fig. 2 is a perspective view of the diaphragm or middle portion; Fig. 3 is a perspective view of one of the outer or body portions: and Figs. 4 and 5 are elevations of my improved valve showing different degrees of oliquity in the flanged portions.

2 is the diaphragm or middle portion and 3 and 4 are the outer flanged body portions which are clamped together by bolts .5 to constitute the body of the valve.

The diaphragm portion 2 is stamped from a sheet ofsteel so as to provide an annular flange rim 6 and an annular seating portion 7, the plane of which is arranged at an angle to the plane of the rim 6, as will be -clearly understood by reference to Figs. 1

and 2. In forming this diaphragm portion 2, the metal is subjected to the action of dies which produce a crescent-shaped drawing of the metal on opposite sides as at 9, 9,

thereby ribbing it and simultaneously thereplane of the flange rim 6. The general con- V struction of this diaphragm portion 2 will be fully understood by reference to Figs. 1 and 2. Its shape is such that it is exceedingly strong when in place between the two body parts 3 and 4. The annular flange 6 is bored or stamped to provide holes for the bolts 5 by which it is positioned and, at the same time, secured in place between the body parts.

The body portions 3 and 4 are the same in all material respects and are made from sheetsteel by suitable dies which draw, press and stamp it into the proper shape. This shape comprises the annular flange 10 to fit upon the flange 6 of the diaphragm portion and through which the bolts 5 pass and the body space 12 which is preferably more or .less semi-spherical and extending from the flange 10, and the port portion 11 formed as a tubular neck of smaller diameter than the large diameter of the body 'portion and secured in a suitable manner to the flange 13. As shown, this flange is attached to the tubular neck 11 by the latter being expanded within the flange as at 14, said expanding being preferably formed with an outward rib extending into the groove of the flange, as illustrated. I, however, do not restrict myselfas to the manner of securing the flange upon the neck 11, as it may be attached in any suitable manner found satisfactory for the work which the valve is required to perform.

Screwed, or otherwise secured in the thoroughfare opening 8 of the valve seat portion 7 of the middle diaphragm portion, is a suitable valve seat 15 which may be formed of brass or other metal and prefer-' ably acting as a guide as well as a seat for the valve.-

16 is the valve piece, which may also be of brass and guided and seating upon the valve seatportion or bushing 15.

17 is the valve-stem and is connected at one end of the valve piece 16- and at the other end to the hand wheel 22 for operating it. This valve stem is screw threaded in the ordinary manner and screws through the bonnet portion 18 for the purpose of opening or closing the valvepiece relatively to its valve seat. The part of the stem nearer the hand wheel extends through the stuffing box 21 in the upper end of the bonnet and by which the valve may be made liquid or gas tight about the stem. The

' bonnet 18 screws into one side of one of the body portions, (as shown, the body portion 4) and to provide a proper seating surface, the collar 20, flat upon its outer surface and curved upon its under surface, may

be interposed between the bonnet and the outer surface of' the body portion 4, as clearly indicated in Figs. 1, 1 and 5. This collar 20 may be securely clamped upon the body portion with a leaded joint or it may be brazed, Welded or otherwise secured to the body portion as desired. The axis of the valve stem 17 is at right angles to the valve seat 15 and hence to the valve seat surface 7 of the middle diaphragm portion 2, so as to properly move the valve piece relatively to and from its seat. This stem -or spindle 17 is preferably arrangedat an ular construction of the valve piece and diaphragm supporting it, is not only at an angle to the plane of the diaphragm 6, but is also at an angle to the axis of the ports 11, 11, and this provides two important benefits. By providing that. the opening in the diaphragm to be controlled by the valve piece shall face the inlet port, so as to present a through passage in alinenient with the axis of the ports of the valve body, the fluid may pass more freely and with less obstruction through the valve than would be possible if the opening in the diaphrgam were in a plane parallel to the axis of the inlet port; and moreover, this transversely oblique arrangement of the thoroughfare or opening in the diaphragm, with reference to the longitudinal axis of the ports of the body, also reduces the depth of the stamped portions 9, 9, thereby strengthening the dia phragm or permitting less weight of metal to be used with equal strength. The axis of the valve stem or spindle being at right angles to the valve seat 15 so as to properly move the valve piece, it follows that as the seat is in a plane obliquely transverse to the longitudinal axis of the ports 11 of the body,

the said valve "stem or spindle is, caused to,

be arranged throughone of the body parts much nearer to its port than to the port of the other body part, this construction pro.- viding the proper space, for supporting the stufling box for the spindle without necessitating too great an angularity to the oblique union between the two body parts and diaphragm portion with respect to the axial line of. the ports. I r

In addition to the advantageous features of my construction set out above, there is a very important feature in respect of the manufacture dependent upon the general relation of the angularity of the plane of the flanges, plane of the valve seat and axis of the spindle with respect to the axial line of the port outlets, because by arranging the flanges of the body portions and the diaphragm portion at approximately .60 degrees to the axial line of the ports and the valve seat and spindle respectively at approximately 30 and 60 degrees to the axial line of the ports, I am enabled to reduce the size of the body portions to small size while maintaining the through passage aforesaid.

In the construction shown in Fig. 1, we have a straight or through valve, but, if desired, the bolts 5 may be removed and the .body portion 3 readjusted to bring its outlet portion or neck 11 into an angular position with respect to the corresponding part of the body portion 4., as will be understood by tions of the belly -part 3 may be had, the

only restriction being the number of bolts 5 employed, as the capacity for different adjustments varies as the number of bolts. All of the bolts are spaced at equal distances apart, so that the several parts 2, 3 and 4 may be reassembled in the various positions as desired. In the particular shape shown in Fig. 1, it is not possible to have the two ports 11 exactly at right angles to each other because the diaphragm portion 6 is greater than 15 to the axial line through the two ports 11 when the body portions are set for a through valve as indicated in Fig. 1. In Fig. l, however, I have shown the obliquity of the diaphragm portion 2 to the axial line of the ports 11 when the body portions are set for a through valve, such that the plane of said diaphragm portion is 45 to said axial line and in which case, it is evident that the two body parts may be adjusted so that the ports and their flanges 13 may be arranged at right angles, as illustrated.

I do not limit myself to any particular angle of the flange 10 of the body parts with respect'to the flange- 13 thereof and have therefore shown in Figs. 4 and 5 two examples, in which, in Fig. 4, these flanges l0 and 13 are arranged at 45 to each other, whereas in Fig. 5 they are arranged at 30 to each other. Any other angle may be employed, if so desired.

It will be understood that in stamping and drawing the body portions 3 and 4, the necks 11 will be of less thickness of metal than the flanges 10, but this is desirable in that the said necks are re-inforced by the extra flanges 13 into which they are expanded.

I have not shown any packing between the several flanges 10, 6, 10, as such is not necessary where the metal surfaces are made true, but it is evident that, if desired, thin gaskets may be arranged between the several flanges to cheapen the construction, the use of such gaskets forming no part of my invention.

It is evident that the particular shape of the dia 'ihragm portion 2 imparts to it great strength, which will prevent distortion by pressure on the inlet side; and it will be further understood that, as this part of the valve may be made from suitable'steel, the

. same may be 'tempered to increase the strength. The essential portion of my invention resides in the middle diaphragm portion when made of pressed and stamped sheet steel or other metal and in which the plane of the seat portion is formed at an angle to the plane of the flanged portion which surrounds it and which is adapted to be clamped between the two body portions irrespective of their construction; and more specifically, my invention resides in the combination of the said diaphragm portion with drawn and stamped sheet metal body portions having angularly arranged flanges as hereinbefore pointed out.

hile in most instances, the ports of the body portions 3-and 4 will be provided with flanges 13, it is evident that, in the smaller sizes of valves, the necks 11 may be screwthreaded for attachment to ordinary pipe fittings or for direct attachment to thepipes themselves and therefore, broadly considered, my invention is not restricted to the employment of a flange about the "ports.

I have shown my invention in the form which I prefer in the commercial adaptation of my invention, but I do not restrict or limit myself to the details thereof, as these may be modified without departing from the spirit of the invention.

Having now described my invention, what I, claim as new and desire to secure by Letters Patent, is
