EBN'EST G. DANIELSON OF BAIV FRANCISCO, CALIFORNIA, ASSIGNOR TO T. CUNN INGRAM, OF SAN FRANCISCO, CALIFORNIA.
ELECTRIC-TUBE sooxs'r.
Application and July 25, 1921. Serial No. 487,505.
To all wkom-it-may concem:
Be it known that I, ERNEST G. DANIEL- soN, a citizen' of the United States, and a resident of the city and county of San Francisco, State of California, have invent d a certain new and useful Electric-Tube So et, of whichthe' following is a specification. The invention relates to sockets for bold ing thermo-ionic tubes, suclr-as are'employed in. radio receiving systems. Tubes of this I type usually com rise a highly evacuated glasstube mounte on abrass base and containing a plate', a grid, and a filament. The filament is delicate andjits life is materially prolonged if thetube' is mounted in such gositionthat the filament is held'verticallyl ome receiving sets are mounted on vertically disposed panels and others are mount ed on horizontal tables and it is an object. of this invention to provide a tube mounting pr socket which may be secured either to-a panelor a table, to hold the tube with the filament vertical. Tube mountings or sockets have usually 55 heretofore comprised an insulating base having abrass or other metallic shell or socket mounted thereon'to receive the metallictube base. This combination of metallic shell ,and metallic base produces a capacitance 80- which is undesirable 'iind another object of this invention is to provide. a tube socket which eliminates th s undesirable capacitance and its consequent ground noises.
- I The invention possesses other advanta- 88 geous features,- some of which, with the foregoing, will be set forth at length in the following description, where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the presentspecification.
In said drawings:
Fig. 1 is aside elevation of the socket sc cured to a-panel and containing one type of I I a tube.
Fig. 2 is a plan view of the socket, as when mounted on a table.
3 is a section taken on the line 3-3, x I. e socket or tube mounting of my invention com rises a base 4.0f insulating material,-pre erably that known in the trade as Bakelite, having a vertically disposed flat face 5 adapted tobear against a panel 6, to
which it is held by screws 7 passing through the panel and seating in the base. The base 1 is also provided with holes 8 through which screws may be passed to hold the mounting to a table. ,The base is preferably countersunk on its under-surface and the marginal edge 9 thus formed is flat so that the'mountmg sets flat on a table. The base is vided with thickened portions 12 exten romg into the countersunk area which form sub- Secured to the base' are binding posts 13 T stantial seats for the screws 7.
to which the electric current leads are attaehed, and disposed in the countersunk area and held in-place by the binding posts are flexible conta'ct'leaves 14 with which the contactson the tube engage. By countersinkmg the'base and arranging the contact leaves in the countersunk area, they may be flexed by the tube contacts and still remain out of contact with the table on which the socket is mounted.
springingfrom the base and formed in- -tegrally..t hcrcwith is a socket 15,01 insulating matkirial, preferably Bakelite, at the bottom (if which the free ends of the contact leaves are disposed. Tlicsc'lcavcs are thus supported directly on the rim of the aperture in the socket 15. The socket is provided with a bayonet clutch socket 16 for locking thc=tubc in place; The tube mount- .ing is preferably formed of piece of molded Bakelite, making it simple and durable. By makin tionof Bakelite instead 0 metal, the losses and ground noises due to the increased capacitance in the socket are eliminated.
The overhanging lip of the bayonet clutch socket is preferably reinforced by a metallic reinforcing member 17 embedded in the- Bakelite and surrounding the socket.
I claim: 1 In a tube mounting, a socket formed of an integral he socket poi:
insulation material, said socket havin a bayonet slot for holding the tube, an a metallic reinforcing member arranged near the slot and held in the insulating material.
In testimony whereof, I havehereunto set- ERNEST e. DANIELSON,
