ENGLAND, ASSIGNOR TO BENJAMIN ELEC- TRIO MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINoIs sHocK ABsoRBrNG lApplication mea october 21, i925, serial No Myinvention relates to shock-absorbing mounts or supports for thermionic valves and other delicate electrical devices, liable to be eHected by shocks or vibrations, and relates particularly to improved spring supports for the valves or other electrical devices, or for the supports therefor.
According to the present invention the shock-absorbing supports, are constituted by-springs, formed from spring strip metal or wire, such as brass, so bent or arranged as to provide gtpr resilient action in both verameter than the upper part.
tical and horizontal directions and ina rotary sense or in a combination of these directions. l. One end of the` spring is formed as or provided with a vertical socket or supporting member while the other end is horizontal or extends out horizontally, the intermediate portion being coiled in a spiral or helix, the spring support constituting at the same time, an electric conductor.
In the preferred form, las a shock-absorbing support for a thermionic valve, we form the springs, preferably four, from spring strip brass, each of which is so bent and coiled at one end as -to form a vertical tube or socket to receive a leg of the valve, the other end extending out horizontally, the intermediate part being coiled around the lower end of the vertical tubular part, or being of greater di- By this construction a spring support is formed which will have a shock-absorbing eiiect in vertical, horizontal and rotary directions, or any combination of these directionsf The invention is illustrated, by way of example, in thel accompanying drawings, as applied to or constructed for a thermionic valve mount or holder. y
Figure 1 represents a vertical section on the line 1-1 of Fig. 2; i i
Fig. 2 is a plan view with one corner of the mount partly broken away;
Fig. 3 shows an elevation of one-.of the springs on an enlarged scale;
Fig. 3a shows in plan view, a modification'thereof;
Fig.` 4 shows on a smaller scale, the spring (Fig. 3) in development,or laid out flat; and` MOUNT on SUPPORT 63,818, and in Great Britain June 30, 1925.
Figs. 5, 5a, 6,7, 8 and 8a show modifications. Referring first to^Figs. 1 to 4, the construction shown comprises a base 1 of bakelite or other insulating material having a central opening 2, the base being recessed on its un.
der'side thereby forming a circular flange 3 around the opening 2, and a disc or holder 4.0i' insulating material having a flange 5 around its lower edge arranged within the opening 2 and provided with holes 6 to receive the legs of a thermionic valve (not shown).
This holder 4 is supported from the base 1 by means of four springs 7, the construction of which will' be described hereafter. The inner end of each spring is constituted by a tubular part. 8, which extends up vertically and ts in one of the holes 6 in the holder 4, its end being preferably flanged outwardly, as
shown at 8a. The other end 9 of the spring.
extends out horizontally and, in the example illustrated, its end lies in a slot -10 formed on the underside of the base, these slots being shown as provided at the corners of the base 1. Each spring 7 is provided with a hole to allow the passage of al securing screw or a screw-threaded extension of a terminal 11, which is secured in place by a nut 12. Each spring is preferably provided at its outer end with a projection 13, in those cases where a soldered connection is required. i
It will be noted that the holder 4 is :freely supported in the opening 2 by the springs 7, its flange 5 lying between the flange 3 and stops 14, which can conveniently be arranged between the outer end of the springs 7' and the underside of the base 1, as shown in Figure 1. ment of the holder 4 will be limited in both directions and undue strain upon the springs of the valve. I
Thus the extent of vertical In'ove- The combinedvertical and horizontal springsheet metal of peculiar shape, one edge` 1 7 a' to 7b, and is coiled once or more around the tubular part 8 while the outer section is I twisted and bent down, as at 7e, so that the part 9 extends out horizontally. When fitted in the holder 4 the projecting part 7 e will vlie just below the underside of the holder 4 and even if the tubular part is pushed up to such an extent that the part 7a comes in contact with the underside ofthe holder the resiliency of the tubular part 8 will not be unduly v affected, since the coiled portion 8a will still lie below and out of contact with the under surface of the holder. Of course, a similar' effect could be obtained by providing a slight lug or upward projection at the point 7a (Fig. 4).
In the modification sholwn in Fig. 3a -the horizontal portion of the spring is shown as corrugated, its outer end being twisted at 7e so as to be at right angle tothe corrugated portion.
The object of employing a spring of this kind is to provide for the necessary resiliency in action in all directions, not only in a vertical direction, 'as such a spring can take up not only vertical stresses but` also those in a horizontal direction, and rotary'direction, or
in a combination of these directions.
A slightly modified form of spring of strip spring metal, is shown in made Fig. 5
40 wherein one end of the strip is bent to form a central socket 8, the strip being then wound in a conical helix and the outer end bent outwards and twisted, as in Figure 3.
This strip may be liat, or as shown in sec- '45 tion in Fig. 5a, it may be of curved cross-section.
While the strip metal construction described has been found to give most -excellent results, a spring of similar shape and characteristics can be made from spirally wound l wire, some such constructions being lllustrated in Figures 6, 7 and 8a'.
In the construction 'shown in Fig. 6 the spring has a middle coiled vertical portion 15 and horizontal end portions,*one end being coiled to form a socket,'or attached to a socket,
as shown, and the other end being formed into' a ring for securing the spring in place, and to a terminal or like connection.
l) Figs. 7 .and 8 show a springv wire bent into `a flat spiral its inner endbeing connected to a vertical socket 8 (Fig. 7), or bent into a cylindrical-socket 8 (Fig. 8,), while its outer end is formed into'a loop or ring 16.
5 The construction shown in Fig. 8a is similar to that shown in Fig. 5, the spring however, being in the form of a fiat spiral instead of a conical helix.
In all cases the spring its intended to act as an electric conductor in addition to its function as a shock absorbing support, and in all cases the construction is such as to allow movement to the holder, valve or other device supported by the springs in vertical, horizontal and rotary..directions, or in a combination of these directions.
It is to be understood that while, for the sake of example, the invention has been illustrated and, principally, described as .applied to a valve holder, it`s`use is not restricted to that, and its ends will therefore be shaped or provided for the particular purpose or device in connection with which it is to be used.
