This invention relates broadly toimproyements in electrical apparatus and more specifically to improvements insockets'for eled tron tubes. I

An object of this invention is to provide.

an electron tube socket from which the electron tube may be readily released for removal or replacement. a

1 Another object of this invention is to provide an electron tube socket in which eflicient' heat radiation isobtained.

A further object of this invention is to provide a compact liquid cooled socket for liquid cooledelectron tubes which efliciently re.

moves the heat developed in the. electron tube.

Other objects and features of this invention will be apparent to'anyoneskilled in the art from the following specification and claims.

According to this invention the depending anode of an electron tube may be removably clamped in a compact and unitary cooling liquid structure. Inlet and outlet ports are provided at the bottom of the structure thereby eliminating connections heretofore employed and which protrude from the sides, this providing a more compact unit. Clamping members are provided at the mouth of the structure for engaging a rim surrounding the anode of the electron discharge device. These clamping members are readily slipped into engagement with the rim and provide means whereby the electron discharge deviceis easily replaced. Adjusting screws are provided on the clamping members whereby the pressure exerted by said clamping members against the rim surrounding the anode may be varied. The inlet port is furthermore provided with a curved passageway extending into the interior of the structure for imparting rotary motion to the water jet issuing from the inlet port. More effective cooling of the anode of the electron discharge device is obtained in this manner.

In the drawings, Figure 1, partly in crosssection, illustrates one embodiment of this invention; Fig. 2 shows a cross-section along the line 22 of Fig. 1; Fig. 3 shows a vertical the depending anode of the electron dissectional View along'the line 33 of Fig. 4 of the base ofthe electron tube socket; and Fig.4 shows a cross-section of the socket structure along the line 1" 1 of Fig. l.

Likereference characters are used to designate like parts throughout all the figures of'the drawings. Referring to Fig. 1 of the drawings in detail, 1- designates a liquid; cooled'electron discharge tube; 2 designates 6O charge tube. A rim or flange 3 is provided on the anode'for' engagement with an inwardly extending flange 7 of the member 7 A tubular member 10 adapted to' surround the anode electrode of the electron discharge device is fittedover the portion '11 of the plug member 13. A tubular member 9 adapted to enclose the tubular member 10 is fitted over' the portion 12' of the member 13. The mem ber 7 is adapted to engage the tubular member 9 at the end opposite to that engaging the member13. J

The electron discharge device 1 is placed with its anode 2 within the tubular member 10 and is supported upon'the flange 7"by' the rim 3. Adjustable clamp members 4 in the form of rocker levers are supported by rod shaped pivot members 6 upon-the"member 7 Adjustable screw members 5 are screw threaded through the member 4. Poretions of the clamp members 1 are adapted to engage therim 3 to holdthe electron discharge device in position with respect to the tubular members 9 andr10. Screw members 5 bear against portions of the member 7 and thereby provide'means whereby the rigidity with which the electron discharge tube is held within the tubular membersmay bevaried.

An electrostatic shield 8 is provided adj acent'to the anode and flares out along-the tube. This shield is made preferably, of relatively thin copper or brass spun into shape and secured by screws or other means' to the member 7. The shield may be made integral with I the member? if desired. -95

The plug. member 13 is provided with'the outlet and inlet ports 15 and "18, respectively. Pipe fittings l6 andi17 for making hose connections to the outlet and

inlet ports

15 and 18 respectively are also provided in the plug member 13. The inlet passage through the member 13 is helical in order to impart rotary motion to the cooling liquid entering the socket structure and facilitate cooling of the anode 2. The pipe fittings 16 and 17 are provided at the bottom of the socket structure in order to reduce the cross-sectional area of the socket and render it less bulky. This type of construction lends itself more readily to design requirements and is also simpler in man ufacture.

In Fig. 2 of the drawings is shown a crosssectional view illustrating the manner 'in which the electron discharge device is se-1 cured in the socket structure. The clamping members I are slidable longitudinally of the pivot member 6 when the screws 5 are loosened. To remove the electron discharge tube it is only necessary to loosen the screws 5 and slide the clamping members 4 on the pivot members 6 back adjacent to the support 19 out of engagement with the flange 3. The position of the clamping members i when the tube 1 is to be removed from the socket is shown in dotted outline in Fig. 2.

In Figs. 3 and 4 are illustrated the helical shaped passage of the liquid cooling medium inlet. The cooling medium passes up through the passage 18 into the space within the tubular member 10. The-cooling medium then comes into contact with the anode of the electron discharge device and passes into the jacket formed between the tubular members 9 and 10 and out through the outlet port 15 as indicated by the arrows.

1 Although I have described this invention with respect to a particular construction it is, of course, understood that various modifications may be made in the detailed constructi on thereof without departing from the scope of this invention as defined by the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States is as follows 1. An apparatus of the class described, including an electron tube having an external anode and a source of electrons there for, a pair of concentrically related jackets arranged to receive said anode, means for circulating a cooling fluid around said anode and between said ackets, means adjacent the top of one of said jackets for securing said anode in position, said means comprising a pair of ball-crank levers, a supporting pivot thermionic tube having an external anode and a source of electrons therefor and comprising a socket structure arranged to receive said anode, a laterally extending flange on said anode, a head carried by said socket structure, a pair of rod members-carried by said head, extending parallel to each other on opposite sides of and in a plane perpendicular to the axis of said socket structure, rockable levers mounted on said rodmembers and adjustable laterally on said rod members with respectto said head from diametrically opposite positions with respect to said flange on said anode to positions beyond said flange for securing or releasing said anode from said socket. l

3. A device of the class described including an electron tube having an external anode and a source of electrons cooperating therewith, a socket structure arranged to receive said anode, a laterally extending flange on said anode, a head carried by said socket structure, said socket structure comprising two fluid conducting members, a pair of parallel pivot rods carried by said head on opposite sides thereof, said rods being substantially perpendicular to the axis of said socket structure, rockable clamps carried respectively by said rods and slidable laterally along said rods and adjustable screws carried by each of said clamps and adapted when adjusted to bear against saidhead and lock said clamps into engagement with the flange of said anode to retain said anode in said socket structure.
