HAROLD H. YOUNG AND EARLB A. RYDER, OF KEYIPORT, NEW JERSEY.

SUPPORT FOR ELECTRICAL APPARATUS.

Application filed March 26, 1924. Serial No. 702,033.

To all whom it may conecm:

Be it known that we. Harrow H. Yoinve and EARLE A. Rvnrn, both citizens of the Unit-d States, and residents of Kcyport, in the county of Monmouth and State. of New Jersey, have invented certain ne and useful Improvements in Supports for Electrical Apparatus, of which the following is a specification, reference being had to the ac companying drawings forming part of this specification.

This invention relates to radio apparatus in general and more specifically to the receiving type of radio systems known as multi-tube sets and in which a number of controlling or operating instruments are usually required.

The present invention features an im proved means by which a multiplicity of controlling or operating instruments may be formed into a unitary assemblage, and a novel method of so grouping the same on a supporting member as form a compact selfcontained unit is herein disclosed.

An object of the invention is to provide a means whereby the principal parts of a radio signalling apparatus such as variable condensers, vacuum tubes, coils, transformers etc., together with their connecting members or lead wires may be pro-assembled into a unit for later introduction-into a suitable case or cabinet.

It is one ofthe prime requisites for the eflicient operation of a signalling set especially where high frequency is employed, to reduce the length of the various connecting Wires to a minimum in order to eliminate stray fields and. undesirable capacity or magnetic coupling.

Therefore it is a further object of this invention to provide a means whereby such indielectic material, the vacuum tubes require each a separate socket for support and operation.

To this end it. is a still further object of the present invention to provide a simple inexpensive method of construction in which ordinary commercially available material may be used to fabricate a support1for a lnultirl'city of such instruments without resorting to the use of expensive dies or molds for forming sockets or other equipment of a like nature.

These various objects we achieve by employing a pair of supporting members readily constructed from standard material and in which no (lies, molds or special machinery are required to fabricate the same.

lVith the construction as herein disclosed it becomes possible to so position the instruments relatively to one-another that the connecting wires may be short and direct and disposed so that they will be very little in evidence. It will be readily understood that with such material reduction in the length of the wiring system, stray coupling will be greatly reduced or entirely climinated and the general appearance much enhanced.

It has been customary in the past. when constructing an apparatus for radio signalling, to mount or secure each instrument individually to a base board or panel and to then establish the necessary connections therebetween. Such a procedure usually resulted in rather a complex wiring system which isobjectionable. Furthermore with the conventional manner of construction sub-assemblies are manifestly impracticable and such sets are usually completely assembled at one time.

lVith the form as herein shown and described We have provided a means whereby either a partial or a complete circuit may be assembled in advance for attachment to a base board or panel at some future time.

Still another object of the invention is to provide supporting means for radio instruments in which the parts are of such construction as to permit of them being distributed to the trade in a knocked down described nation an (i no features of novelty id/C1115 particularly in the claims at the specincation.

in the tilrawingst-- Figure 1 isv a plan view of the invention.

Figure 2 is a front elevation.

Figure 3 is an end view of Figs. and 2 as looking from the right hand end. i n he present instance 10 and 11 designates a pair of upstanding spaced apart nails preferably formed of dielect ic material such as bakelite and provided with a series of perforations 11 for the reception of portions of the instruments to be mounted thereon.

A plurality of variable condensers 12 are disposed between the walls '10 and 11 and secured thereto by means of the tie-bolts 13 which extend through the fixed plates of the condensers 12 and the perforations 11.

Alternately spaced with the condensers, provisions are made for the reception of a number of vacuum tubes, in which the trans versely disposed rods 14 act in conjunction with the walls as a lateral support for the lower portion of the tubes 15. Springs 16 are secured to the walls by the screws 17 and are of such construction as to make contact with the tube terminals 18 when the tubes are inserted in their respective openings. A means for holding the tubes in a relatively fixed, position with the springs 16 is provided by the'bayonet slots 19 formed inthe wall 10 and adapted to receive the locking pin on the tube.

A; top plate or cover portion 20 may be provided to insure the proper introduction of the tubes with referenceto the springs 16 which would prevent the burning out of tubes by the inexperienced, or a metal ferrule may be inserted between the walls for the same purpose; this feature is however optional and not actually necessary for the proper functioning of the device.

To the wall 11 there is secured in any suitable manner as by the bolts 13 a number of bosses 21 by which the'unit may be attached to a panel 22 by means of the screws as shown.

On the exterior of the walls 10, 11 a number of other instruments may be accommodated such as coils 28, transformers 24 and rheostats 25 and which can be secured in any preferred manner as by the brackets 29. V V

The filament lead wires 26, 27 are connected to the springs 16 as shown in Fig. 2 and are usually soldered. Other connections are madein a similar manner as shown able cone which a lead 28 is bro 'p' the tie bolt to the s-ipr urdica" k, id terminal.

It W1 be seen from the drmvings that :1 number of instruments can be convenieiuty ormed to a compact unit as hereinluriorc describec, .nd whereas there is shown in the present ibodiment a plurality of ensers and tubes, it is to be um stood however that the invention is not restricted in its scope to the exclusive use of such instruments as shown in'the drawings nor to the manner of their disposition relative to 'one another. it will be appreciated that in radio apparatus employing a multiplicity of vacuum tubes it would be advantageous to form an exclusive tube supporting unit in the above described manner in which any number of tubes may be disposed adjacent to one-another and a sinilar unit constructed for the support of the condensers, etc. This would eliminate numerous tube sockets and other expensive material. v

As a convenience-to those who wish to build their own the supporting means, comprising the walls suitably perforated to accommodate a variety of instruments may be distributed commercially either singly or in pairs.

lVe have stated that the walls are preferably formed of dielectric material; it is however considered within the scope of this invention to form said walls of metal or any electricallyconductive material and to suitably insulate the instruments therefrom as by non-conductive bushings; in

fact a certain advantage may accrue in so,

constructing said walls and connecting them with a convenient ground wire. \Vhen formed of such material, the walls would act as a shield to prevent the effect of body capacity of the operator so annoying at times during the operation of a receiving set.

Variations may be resorted to within the I scope of the invention and portions of the improvements may be used without the others.

Having thus described our invention, we claim:
