Our invention relates broadly to' electron tube apparatus and more particularly to? a water cooled mounting" for high power electron tubes.

Oneof the objects of our invention is to provide an improved resilient' support for high power' electron tubes having vmeans'for circulating a cooling :duid about the anode ofthe tube, -1

I notherobje'ct of our inventionv is to provide a hi-ghpowertube support having a' water circulating jacket' arranged to receive tubes of' differing anode sizes and arranged o'r maintaining the temperature of a tube in the support substantially constant during long periods ofj operation.

Our inventionwill be'more fully understood from they specification hereinafter follow-ing by reference to the accompanying drawingsin which:

tube" support taken' oir lineV 4-4l of Figi 1.

Owing to" variatiors insize of ane'desj of water-cooled@ tubes of different manufactufersf, we have vround it necessary to constriuct socket that' is' quickly adaptable to tnbesfof various'lnanufactu-rers. This isac* complished by the insertion or removalv of a metal sleeve 1 insifdfejthe water jacket 12, the

thickness of the wall on'said metal sleevebeingr such as to reducethe water space to a predetermined best value, and thus accommodate a tubefhayinga smaller anode. The tubeV mounting' is* provided with header constructed of twoparts as indicated by reference characters 1f'an'd2. Header'portion 2 isl secured to fluid jacket 12 near lone end thereof. The parts 1 and2' of the header are se' shaped that their adjacent portions" form Vespace for passage of cooling' fluidl from" the jacket 12 tothe outlet pipef22`. The joint between' the headerpo'rtioiis 1'` and' 2 ismade lsecured to water 'for'rnjed' water passage 14 forv the purpose of land air bubbles while wate'rtight by means of gasket 5.y Theparts of the header be held together byserews or' inv other suitable manner. The divided construction of the' head' .also an afd'va'iltagev of easy access to the inner cham-ber for cleaning; purposes.

Werr provide centering screws 3 for' centering' the anode 16 of tube 17 withinv the 4jacket 4and" thusequalize the water space 15. The

centering' screws when set for the larger tube need not be disturbed for the insertion of the' sleeve 4 for the accommodation of the smaller tubei The sleeve 4: having slots 6 affords at its lower end' is adapted to slip over the pins 3L The sl'eeve'tin turn' has secured to itself three additional pins for centering a smaller anode withinizinlg the water space 15. The sleeve' 4 also may have a lug 9 attached to its upper endto prevent accidental raisin-g` of the' sleeve and closingof the watere'xit 18 aroundY the -neck of the tube.v The sleeve 4, also has a" slotV 8 cut the' full length ofy its side, the purpose of 'which is to'ca'usey the' sleeve to spring out when placed insidethe'waterjaeket i2' andfit snugly against thewal'ls of the. latter.` The slotis made narrow to prevent excess of wadiameter anode: are held pla-ce by a metal 'ring 10T fas'tenfedtothe outerw'all'of the water jacket 12', high enough tov centerproperly* a vacuum tube" of' minimum length, while the water jacket is madelongfenough to accommodate a vacuum tubeof m'aiimuin length.

A detachable ehu member or header i3 is j acket 12 having a` spirally preventing the formationA of eddy currents the water is-'passing through the jacketl 'It' has been found that after'a tube has been in use for some time there is a' tendency of' the tubeto adhere to the socketv and breakag'emay result if force is used initsremoval. In orderto facilitate removal", slots 19 have been" provided in the socket head 1 to permit of' the insertion of narrew screw'-v driver orsimilar vtool 11n-der the shoulder'2'0 ofT the'tiibe' 17' andI thereby *loosen* the tube) Without" injury'.` Holes 11 the sleeve 'and Iequalare provided for the insertion of a hook for withdrawing sleeve 4 from jacket 12 when a different size tube is to be mounted in the socket.

The water enters at 21, circulates around the annular space 15 and over the gap 18, and leaves at the pipe 22. An electrostatic shield 23 is provided at the top of the tube mounting. Slidablelatches 24 and 25 enter opposite sides of the'shield for locking the tube 17 in the socket.

A frame structure for mounting the tube is concentrically disposed about the tube. A pair of insulators 26 and 27 carry the frame structure 28 on which is mounted the ring -members 29 and 30. Spiral spring members Y 31 and 32 are disposed between the ring members 29 and 30 and the header 2 and end member or header 13 for resiliently suspending the tube structure and preventing excess shocks and vibrations reaching the tube 17.

The structure of tube mounting according to our invention has been found to be highly practical in its construction and successful in its operation, and while we have described the invention in its preferred embodiment, we desire that it be understood that modifications may be made and that no limitations upon the invention are intended other than are imposed by the scope claims. f What we claim as new and desire to secure by Letters Patent of the United States is as follows: Y
