9 Claims. (01. 250-275) This invention relates to mountings for electrical devices and more particularly to cushion type mountings for supporting electron discharge and similar devices in a horizontal posi- 5 tion from a vertical support or panel.
Cushion type mountings for electron discharge devices and the like usually comprise, in general, a base or support portion, a socket, and resilient members supporting the socket from the base or support portion. When such mountings are used for supporting an electron discharge device or the like in a horizontal position, the stresses in the resilient members are excessive so that undesirable tilting of the socket member and un- 15 satisfactory cushioning of the device results.
One object of this invention is to prevent excessive stressing of the resilient members in cushion type mountings for supporting electron discharge devices and the like in a horizontal 20 position on a vertical support or panel.
In one embodiment illustrative of this inven-, tion, a mounting comprises a base adapted to be secured to a vertical support or panel, a socket having a plurality of horizontal apertures for receiving terminal prongs on the device to be supported, and a plurality of resilient members supporting the socket from the base.
In accordance with a feature of this invention, an auxiliary resilient support is provided on the base member and adapted to engage the device to be supported whereby the stresses in the resilient supporting members are reduced. The auxiliary support may be in the form of a hanger having a supporting portion secured to the base 35 of the mounting, a cradle portion in which the electron discharge or other device may rest, and coiled springs connecting the cradle and supporting portion.
The invention and the various features thereof will be understood more clearly and fully from the following detailed description with reference to the accompanying drawings, in which:
Fig. 1 is a perspective view of a mounting constructed in accordance with this invention mounted on a vertical panel, with a portion of an electron discharge device supported by the mounting shown in dotted outline;
Fig. 2 is a front view partly in section of the mounting shown in Fig. 1 with the auxiliary support omitted;
Fig. 3 is a side elevational view of the mounting shown in Fig. 1, partly in cross-section along the line 33 of Fig. 2;
Fig. 4 is an enlarged detail perspective view of one of the terminal and contact members embodied in the mounting shown in Figs. 1 to 3;
Fig. 5 is another enlarged detail perspective view illustrating a modification of the terminal and contact member shown in Fig. 4; and
Figs. 6 and 7 are perspective views of modifications of the auxiliary support shown in Figs. 1 and 2.
Referring now to the drawings, the mounting shown in Figs. 1 to 3, inclusive, comprises-a base or support portion including two substantially square similar base or support members l and II, which may be of insulating material, such as a phenolic condensation product, secured together by a plurality of eyelets I2 and forming a central recess l3. Disposed within the recess is and spaced from the inner walls of the members l0 and l l is a socket member, which also may be of an insulating material, such as a phenolic condensation product, and which includes a body portion [4 and a base plate l secured to the body portion I4 by a central eyelet [6. The body portion [4 is provided with a plurality of apertures [1 for receiving the terminal prongs of an electron discharge device, or the like, and is provided alsowith a plurality of recesses 8 disposed one below-and in communication with each of the apertures H.
The socket member is resiliently supported within the recess l3 by a plurality of metallic members which may be, for example, of phosphor bronze, each of which, as shown clearly in Fig. 4, comprises a terminal portion I 9, a U-shaped contact portion 20, and an intermediate resilient portion 2|. Each terminal portion I9 is substantially L-shaped and is held between two plate members 22 and 23, which may be of insulating material, such as a phenolic condensation product, secured to the supportmember II by the eyelets l2. Each of the contact portions 20, as shown clearlyin Fig. 2, is disposed in one of the recesses l8, being positioned longitudinally by the top of the body portion l4 and the plate l5, and has parallel arm portions 24 frictionally held in slots or grooves 25 in the body portion I5. Each contact portion 20 is provided also with integral projections 26 which abut against the inner wall of the body portion l5 and with guide lips 21 which are in axial alignment with the corresponding aperture ll.
As shown in Fig. 5, the intermediate portion of.
tioned in an aperture 15 in the wall or panel by bolts 3| which extend through the eyelets l3. If a device, such as an electron discharge device 32, is carried by the socket l4, l5, because of the weight of the device, the socket may contact with the support members l0 and I I so that the device will not be supported resiliently and the electrodes thereof will not be protected against shocks and jars. Furthermore, the resilient portions 2| may be subjected to excessive stresses so that they may acquire a permanent set and the resiliency thereof may be materially decreased.
In accordance with this invention, the aforementioned difficulties are overcome by providing an auxiliary resilient support which carries a large part of the weight of the device 32 and holds it in such position that the socket member is maintained out of contact with the support members l0 and I.
In one illustrative embodiment shown in Figs. 1 and 3, the auxiliary support comprises a pair of resilient arms 33 which may be of sheet metal, each secured to the wall or panel by one of the bolts 3i and having an integral bent bracket portion 34 extending into the aperture 15 and engaging the wall or panel to firmly position the arms 33. A flexible strip 35 of fabric or similar material passes around extensions 36 on the arms 33 and is adapted to be engaged by the device 32. Preferably, the arms 33 and strip 35 are so formed that when the device 32 is in position, the longitudinal axis of the device 32 is at right angles to the plane of the panel or wall 30. It will be apparent, then, that the device 32 is fioatingly supported by the auxiliary support and the resilient portions 2| without excessive stressing of the resilient portions 2|.
In another illustrative embodiment shown in Fig. 6, the auxiliary support comprises a U- shaped frame member 31 which may be formed of a wire rod, provided with arcuate portions 36 adapted to be engaged by the heads of securing members such as the bolts 3| for mounting the auxiliary support on the vertical wall or panel 30. The auxiliary support shown in Fig. 6 includes also another frame member which also may be formed of a wire rod, having arms 39 secured to the frame member 31 as by welding, a hanger portion 40 adapted to engage the device 32, and resilient loop portions 4|.
In still another embodiment shown in Fig. '7, the auxiliary support comprises a U-shaped member 42 which may be formed of a wire rod, having parallel forwardly extending arms 43 to which a strip 44 of fabric or the like is suitably secured, the strip 44 being adapted to engage the device 32. The U -shaped member has secured thereto, as by welding, metallic washers 45 for receiving the bolts 3| or the like for securingthe auxiliary support to the vertical wall or panel 3|].
Although specific embodiments of this invention have been shown and described, it will be understood, of course, that modifications may be made therein without departing from the scope and spirit of this invention as defined in the appended claims.
