GLASS SPRING FOR SECURNG ELECTRICAL UNITS Filed May 25. 1945 Patented May 11, 1948 'Pli'rrsn'rA OFFICE 2.441,::4 GLAss srnmc son sncUiuNG ELECTRICAL Um'rs Harry Robertson Dillon, Niagara Falls, N. Y. i Application May 23, 1945., Serial No. 595,398
2 Claims. 1
This invention relates to securement devices, and particularly concerns such devices commonly used in conjunction with electrical equipment.
As is well known in the field of electricity our# rent traverses the path of least resistance. Also an increase of resistance likewise increases the Another object of this invention is the provi: no
sion of a device constructed of an insulating and non-corrosive material for maintaining a proper constant electrical circuit to which it is applied.
A further object o! this invention is the provision of a device constructed of insulating material adapted to maintain contacts in an 'electrical circuit'l in spaced relation to each other and permitting said contacts to be closed to provide a path for an electric current.
Other objects and features will more fully appear from the following description and accompanying drawings in which Fig. 1 is a vertical view showing the securement device as applied in tubes in a radio apparatus; Fig. 2 a vertical view of the device; Fig. .'l a, sectional view of a portion thereof; Fig. 4 a sectional view, and Fig. 5 a sectional viewshowing a tube secured in horizontal position by the device.
Referring to the drawings a spring l which may be constructed of any insulating material; but preferably of glass, is provided with serrations 2 disposed on each of the ends of said spring.
'Ihese serrations, as is obvious, tend to prevent displacement of said spring and those portions of the surfaces they contact.
As shown in Fig. 1 a radio cabinet 3 is provided with a chassis I upon which is mounted the various electrical units such as a number of radio tubes 5, a transformer 6, and a shield 1, as is well known in the art.
It isobvious from the foregoing that radio tubes being adapted for insertion in the chassis to make electrical contact with an electrical circuit (not shown) therein often fail to maintain proper l electrical contact due to vibration. expansion and contraction and many other causes well known in the art.
By the insertion of springs I between the tubes and cabinet pressure is exerted upon said tubes 10 to maintain constant electrical contact between said tubes and their respective electrical circuits.
As clearly set forth in Fig. 4 constant electrical contact may be applied to various types of tubes, and in this particular case the so-called peanut 1s tube while in Fig.l 5 suchcontact is maintained with the tube in horizontal position, thereby clearly showing the device may be applied to various electrical units positioned in any angle or plane.
It isfto be understood that the spring may be applied to any electrical apparatus in electrical contact, such for instance, as used in connection with carbon brushes on a motor, generator, or the like. gs Having described this invention,
claimed is:
1. In a. device of the character described, for preventing displacement of the securement device of an electrical unit relative to the chassis of a 80 supporting cabinet, the combination of a supporting frame member and a supported element thereon containing the terminal portion of an electrical circuit, an electrical unit having an electrical conducting terminal at one end, and an 35 insulated spring seat at the other end, and a helical compression -spring disposed between the frame member and the said spring seat of the electrical unit; the terminal of the spring adjacent the' frame member being provided with ser- -40 rations, detachably gripping said frame member and readily separable therefrom, thereby mainwhat is taining constant electrical contact of the said electrical conducting terminal with said portion of an electrical circuit and obviating the produc- 46 tion of heat due to increase in resistance, said spring being formed from glass, thereby preventing magnetic disturbance and obtaining greater electrical insulation of the parts.
2. In a device o! the character setA forth in 5o claim 1, the opposite terminal of said compression 3 spring being also provided with serratiom de- Number tachably gripping the opposing end surface o! 1,984,817 said spring ses* of the electrical unit. 2,021,278 HARRY ROBERTSON DILLON. 2,032,493.
