UNITED s'r'rs EDWARD E. STEVENSON, OE LOS ANGELES, CALIFORNIA, ASSIGNOR T EMSCO DERRICK AND EQUIPMENT COMPANY, OFLOS ANGELES, CALIFORNIA METHOD OF MAKING BLIND CAGE SLEEVES WITH BALL GUIDE INTEGRAL Application filed March 7, 1930. Serial No. 433,965.
This invention relates to a valve cage and method of making the same.
An object of the invention, considered as a new article of manufacture, is to provide a valve cage having the maximum strength and durability possible to secure with the use of the minimum amount of weight and material.
It has sometimes been customary to provide guide ribs within a valve cage for a ball valve, making said ribs entirely separate from the sleeve. In such cases the sleeve could not be reinforced from the material contained in the ribs. Another method of constructing valve cages has been to cast the ribs within the sleeve as an integral part thereof, but this method has not proven entirely satisfactory, due to the kind of material necessary to use in such a process and due to the roughness of the cast surfaces.
By using the method provided by this invention, the sleeve is progressively wrought upon by a series of operations whereby it is formed into the proper shape and at the same time internal ribs are formed integral therewith.
Other objects, advantages and features of invention, both with regard to the new article of manufacture thereby produced, and with regard to the method whereby said article of manufacture is constructed, may hereinafter appear.
Referring to the accompanying drawing, which illustrates what is at present deemed to be a preferred embodiment of the invention,
Fig. 1 is a longitudinal mid-section of a c lindrical metal tube which is subjected to the various steps of the method and from which the valve cage is produced.
Figs. 2, 3. 4. and 5 illustrate consecutively the progressive steps which are performed in carrving out the method.
Figs. 6 to 10. inclusive, are each end views of the sectional views opposite to which they are respectively located.
Referring in detail to the drawing, the first step of this newly invented method consists in subjecting a cylindrical piece 15, preferably made of forged steel, to the action of a-drill whereby an axialhole 16 is'drilled therethrough. v The second step of the method consists in forming, by broaching or equivalent methods the longitudinal internal ribs 17, four of these The fourth step of the method consists in V turning off the metal portion 20 of the external surface thus bringing down the exterior surface of the sleeve to a uniform diameter as shown in Fig. 4. Afurther part of this step of the method consists in boringj out the internally'contracted portion 22 at each end of the sleeve as indicated in dotted lines in Fig. 4:, with the result that the internal ly ribbed central portion measured from the inner sides of its ribs, is of the same internal diameter as theremainder ofthe tube. 7
These lasttwo operations may be performed in the order stated orin the reverse order or simultaneously, as desired. After these op erations have all been performed, screw threads 25 are tapped into one end of the finished sleeve 26 in orderto receive the externally screw threaded valve retaining ring (not shown).
In Fig. 5 a ball valve 30 is indicated in dotted lines Within the valve cage this valve being of as great a size as can be inserted past the contracted portions 31 adjacent the ends of the valve cage.
I claim 1. The method of constrcting a valve cage which consists in boring a hole axially through a cylindrical piece of steel, then forming within the tube thus made longitudinal ribs by means of channeling out from end to end of said tube circumferentially spaced recesses, then swedging down both end portions of the internally ribbed sleeve thus formed, thus lessening both the internal and external diameter of the end portions thereof, and then in boring out said contracted end signature portions and thus increasing their internal diameter to substantially the same diameter as the internal diameter of said body portion measured between the inner edges of the ribs thereof.
2. The method of constructing a valve cagev which consists in. boring, a. hole axially through a cylindrical piece of steel, then forming within the tube thus made longitudinal ribs by means of channeling out channelsfrom end to end of the tube, then swedging' down both end portions of the internally ribbed sleeve thus formed, thus lessening both the internal and external diameter ofthe end. portions thereof, and then in boring outsaid contracted end portions, and thus increasing.
the internal diameter of'each of said endportions a sufiicient amount to. remove the ribbed sutfiices within thev contracted. end. portions" of the tube.
3.. The method. ofconstructing a valve cage which consists in; boring a hole axially through. a cylindrical piece: oi metal, then forming withinthe tubethus made longitudi- 1121.1. ribsv by means. 05 machining: channels from. endito end. of said. tube,.thenswedging.
down an end: portion ofthe internally ribbed sleeve thus formed, thus lessening both the internal and; external.- diameter of. such end portion thereof, andthen in boning out said contracted end portion to. increase the internalldiameter thereofand' render it smooth.
4.. Themethod oli constructing azvalve-cage which. consists in boring a: hole axially through a cylindrical. piece; of metal-,then forming within the tube thusmade longitudinalribs by means of machiningout channels fromrencltoend of saidtube, then swedging, down both. end portionsof the internally ribbed'sleeve thus formed, thus lessening both.
the internal andexternaldiameter of the. end
portions/thereof, and then. in boringr' out saidcontracted end portions,
lirtestimony whereof I hereunto aflix. my
