VALVE.

Application file d January 1651920, SeriaTNo. 351,802. Renewed September 3, 1920. Serial No. 407,911.

To all whom it may concern:

Be it known that I, HARRY B. BEDDING, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented certain. new and useful Improvements in Valves, of which the following is a specification.

This invention relates to improvements in valves, and has particular reference to'the casing formation of hand operated valves in particular, the object of the invention being to provide a valve casing wherein is embodied an improved stem supporting and guarding structure, which latter is formed in a manner which is very economical to'produce and is substantial, effective and practical in operation and service.

For a further understanding of the invention, reference is to be had to the following description and to the accompanying drawings, in which:

Figure 1 is a side elevation of a valve casing constructed in accordance with the principles of the present invention.

Fig. 2 is an edge elevation of said casing.

Fig. 3 isa vertical sectional view taken along the line 33 of Fig. 2.

Fig. 4 is a transverse sectional view taken along the line 1- 4; of Fig. 3.

Fig. 5 is a similar view taken along the line 55 of Fig. 3.

Fig. 6 is a detail view of the stock from which the stem supporting standard is formed.

Fig. 7 is a similar view showing the manner in which the standard is expanded, and,

Fig. 8 is a view showing the completed standard.

In carrying out the steps of my invention,

use is made of a valve casing 1, which consists essentially of a vertical closure receiving portion 2 and intercepting fluid conduits 3. The outer ends of the conduits may be equipped with flanges 4 by means of which pipes or other suitable fluid conducting elements may be connected with the casing.

" The steps taken in the construction of this casing have been particularly described in my co-pending application bearing Serial Number 351,801, and filing date January 16, 1920, and accordingly, the casing 1 does'not in itself form any part of the present invention.

The upper end of the portion 2 is prowhich is mounted the base member 6 of a stem supporting structure 7. The'member 6 is preferably'-' formed from a flat blank of metal and may have its edges provided with suitable openings ,for the reception of securlng elements, which are employed as usual for the purpose of securely fastening the supporting structure 7 to the casing 1.

he member 6 is further formed with a central opening through which projects the upper threaded end of a valve stem 8 by means of which a valve structure (not shown) situated in the portion 2 may be actuated. Preferably a packing 9 is provided for thepurpose of surrounding the stem 8 at a point where the latter projects through the base member 6, and said packing functions in the customary manner to prevent undue escape of fluid from the valve casing 1. The packing 9 may be contained within a cup 10 integrally formed upon the outer surface of the base member, and a nut 11 may be telescopically mounted within the cup 10 for the purpose of applying suitable pressure to the packing 9, as will be clearly understood.

The stem supporting structure 7 further includes a standard 12 which is formed to embody an upper tubular portion 13 and downwardly and outwardly flaring leg mem Patented Mar. 1, 1921. Y i

portion of the standard12 will be materially reinforced. An internally threaded nut'16 is threadedly positioned upon the upper end of the stem 8, and is connected with a hand wheel 17 by means of a set screw 01. the like 18 whereby upon the rotation of said wheel, said nut will be revolved in uni son therewith and the stem 8 will be raised and lowered in the conventional manner. The hub of the wheel 7 is situated so as to rest upon the upper circular edges of the tubular portion 13 and the bushing 15 and 1s thus insured of a positive and substantial seat, while the lower end of the nut 16 is provided with an out-turned collar 19, which extends into engagement with the lower edge of the bushing 15. Thus by the presence of the bushing, said nut willbe prevented from being raised or the wheel 17.

The present invention consists essentially in the standard construction 12 which as will be observed is of such formation as to.

substantially enhouse the threaded end of the valve stem and also to provide a permanent and effective seat for the wheel 17 and its component parts. This standard is formed as shown in Fig. 6, from a suitable length of tubular stock, which is cut or otherwise operated upon so as to registering slots 20 therein. These s ots are of relatively greater width than their upper ends, and their sides 21 converge toward the center of the stock, and in fact are brought into engagement with each other at the lower end of the standard, so that said slots when initially formed and cut from the standard will be of substantially triangular formation. The next step in operation is to spread the lower ends of the standard so as to produce the downwardly and outwardly flaring leg members 14 until the same have assumed such positions as will be advantageous in connecting the same with the base member 6. Then to flatten the lower ends of the leg members and to expand their general width at the lower ends thereof, said leg members are flattened as at 22 to produce the configuration clearly disclosed in Fig. 8 of the drawings. When this'form has been reached, the lower ends of said standard are positioned properly upon the upper surface of the base member 6, and are then welded thereto, so that the said base member and standard when completed will be of substantially an integral, homogeneous and substantial construction. 1

It will be manifest that by virtue of the lowered upon the rotation of roduce construction described the process offorming the super-structure of a valve casing will be considerably facilitated. The standard produces a maximum degree of strength 1.. The herein described'method for producing valve stem supporting standards, which, consists in theprovision of a metallic tube of suitable dimensions, in providing registerin slots of tapering configuration in the opposite sides of said tube, said slots being terminated at one end of said tube, in flaring the ortions of said tube in an outward directlon so as to produce downwardly and outwardly converging leg members, and in welding said leg members to the base member.

2. The herein described method for pro- This is the result of eliminating used for the pur ducing valve stem standards, which consists in the provision of a metal tube, in producing elongated tapering slots in the'length of said tube, said slots having their lower converging ends'terminated at one end of said tube and their other relatively broadened ends in spaced relation from the other end of said tube whereby a sleeve is produced in said latter end, in spreading the portions of said tube surrounding said slots in an outward direction so as to produce downwardly and outwardly extending leg members, and in securing said leg members by a welding process to the base member.

In testimony whereof I affix my signature.

HARRY B. BEDDING.
