(01. 251-8) 1 2 This invention relates to combination valve structure, and is a division of my application for Letters Patent of the United States ?led Febru ary 22, 1943, for improvements in Transformer cooling means, Serial No. 476,781. Objects of the invention include the provision As disclosed in my patent application above identi?ed the device of the present invention was designed primarily for use in connection with means for water-cooling existing types of elec trical transformers, which means includes as a part thereof a header pipe surrounding the up» of a novel form of valve structure; the provi sion of a'valve structure including a universally mounted discharge member and a valve member per end of an electrical transformer in outwardly spaced relation with respect thereto. At inter cap, and means co-operable between the cap of the spray from the various nozzles and the amount of water ejected from each. one inde pendently of the rest so as to enable an equal vals in the length of the header spray nozzles co-operable therewith to control the volume of 10 are mounted for the purpose of directing a spray flow through said discharge member; the provi of water therefrom upon the surface of the trans sion of a structure of the type described includ former to thereby cool it and permit it to run ing a main body portion having a passage there continuously in excess of its rated or normal ca through, a valve co-‘operable with the passage pacity. In view of the fact that such transform to control the ?ow of ?uid therethrough, a cap 15 el‘s are conventionally placed out of doors and adiustably mounted on the main body portion, often in the path of prevailing winds, it was a discharge member universally mounted on the found desirable to be able to vary the direction and body for controlling the position of the valve; the provision of a construction as above described including means for maintaining the joint be tween the universally mounted discharge mem her and the body against leakage therebetween; and the provision of a construction as above de scribed in which the discharge member comprises cooling of the transformer around its entire pe- ' riphery to be obtained despite such wind or other conditions. The present invention was conceived as an answer to such problems and while it is . shown and described herein as applied to its a spray nozzle. originally intended use, it will be appreciated that it and particularly the form of discharge member therefore may be varied to accommodate novel features of construction and combinations any particular use to which it may be put. Referring now to the drawing, in Figs. 1 and of parts to be hereinafter described with refer ence to the accompanying drawing, and then 2 a portion of the header pipe above referred to claimed, having the above objects in view. is indicated at Ill, the portion of the same there In the accompanying drawing which illus shown being provided, as indicated in Fig. 2, with trates a suitable embodiment of the present in-1 an opening I2 through its bottom wall in which vention and in which like numerals refer to like 35 is relatively closely received the short pilot por parts throughout the several di?erent views, tion 14 of a ?tting I6 secured thereto by weld~ Fig. 1 is a side elevational View of my‘ improved ing, brazing, soldering or the like as at lit.

For instance, as illustrated in Fig. 28 and concentric with the center of the surface 3, the cap member 28 may, if desired, be threaded 30, thereby providing a construction wherein the ball member 32 is prevented from downward . upwardly upon the body portion 26 to such an extent as to bring the ball valve 52 into contact movement through the cap 28 and is universally movable upon the seat 30 with respect to the cap 10 with the seat 22, under which conditions the flow of ?uid through the device will be completely shut 28 and body 26. 01f.
