'Thisinvention relates to an improvement in supports for vacuum tubes for use in radio apparatuses, and has for its object to 'provide a sup ort 'of'simplel Construction capable of re ucing to a minimum the shocks and vibrations that may be transmitted from outside sources through'the support to the delicate mechanism of the vacuum tube, said shocks and vibrations often tending torel duce the efliciency of said tube and interfere seriously with its'operation.v

'It is still furtheran object of the invention to embody. in the structure of thesupport a plurality of. springs, each of said springs being formed of a continuous length of wire and having a torsioncoil formed integral therewith which is also utilized in securing the spring to the vacuum tube socket and said torsion coil has a contact arm projecting laterally therefrom and adapted to engage a terminal of said vacuum tube, said springs constituting electric circuitconnectlons to the terminals of said Vacuum tube.

Still another object of-the invention is to embody in the construction of the supporting springs a loop which is utilized in securing the support to its base. I v

The invention consists in a support for a vacuum tube as set forth inthe following specification and particularly aspointed out' in the claims thereof.

Referring to the drawings Figure 1 represents a central vertical section through a vacuum tube supportembodying my invention. A

Fig. 2 is a plan view of said support.

Fig. 3 is a detail plan view of one of the p n Like numerals refer to like'parts throughoutthe several views of the drawings.

In the drawings, 5 represents a panel constituting'abase, and constructed of suitable I insulating material. Located above the base 5 is a socket 6 also constructed of insulating material and adapted to'rec'eive and hold a vacuum tube of well known construction.

The socket 6 is yieldingl supported above the base 5 by a plurality o springs 7, each of which is formed of a continuous lengthof;

; wire and embodies thereina torsion coil 5, and said s ring. is fastened-to the under sur-v face of a nge 9 of said. socket 6 by an eye let 10, the latter extending through said;

coil and flange and having the opposite ends thereof turned ,over inthe usual well known] manner... The. springs I, 'furthermor'e,v on,-

stitute electric ci'rizuit 'connectlonsto the vacuum tube, there being a resilient contact arm 11 projecting laterally from the upper-, I end 'of each torsion coil 8, and said arm" terminates in a semi-circular portion 12 :which is I minal pin 16 of a vacuum tube and. form an electrical contact therewit Each spring 7 also embodies therein an arm 13 which projects laterally and downwardly from the lower end of the torsion'coil '8, 'and said arm terminates in a"loop.14,,

adapted to partially encircle a ter- 1 f I which-is utilized in securing said spring 7-to the base 5, a binding post'15 preferably be ing employed as a fastening member. The

median lines of the loop 14 and torsion coil 8 are parallel to each other and perpendicu lar to the upper surface of the base 5 and the 5 contact arm 11 is preferably parallel to the upper surface of said base. Betweenthe.

torsion coil 8 and loop .14 there is sufficient inclination to the arm 13 to causeithe spring 7 to yieldingly support the socket 6 above the upper surface of the base 5,and said springs 7 will absorb the shocks andvibrations transmitted thereto and prevent injury to the delicate mechanism of the vacuum tube.

- In inserting a vacuum tube in the socket 6, said tube is given a short rotating movement in the direction of the arrow at in Fig. 2 and during this rotating movement, the terminal pins 16 of said tubewill engage the'semicircular extremities 12 of the contact arms 11 and the latter will thereafter have a yield ing engagement with said ins.

It is evident that if it 18 so desired any suitable form of fastening member may be utilized in securing the support for the vacuum tube tothe base 5, said fastening member bein and base, and a connecting wire may be attached to said fastening member in any of the usual well known manners.
