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

amount of water ejected from each. one inde

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

adiustably mounted on the main body portion,
often in the path of prevailing winds, it was
a discharge member universally mounted on the

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

that it and particularly the form of discharge

novel features of construction and combinations
