13 Claims.

This invention relates generally to an article of furniture embodying radio receiving apparatus and refers more particularly to an article of furniture comprising a base section housing parts of the radio receiving apparatus and a pedestal section clamped at its lower end to a shell having means associated therewith for adjusting certain parts of the radio receiving apparatus in the base section.

It is one of the principal objects of this invention to provide an article of furniture of the type set forth above composed of a relatively few simple parts capable of being inexpensively manufactured and expediently assembled.

Another object of the present invention is to providea shell comprising an inverted substantially cup-shaped part having the top wall removably clamped to the lower end of the pedestal section in concentric relation to the axis of the pedestal by cooperating means carried by the pedestal and base sections respectively.

Another object of this invention is to clamp the top wall of the shell part against the lower end of the pedestal section by means of a coupling having theupper end detachably secured to the lower end of a member anchored in the pedestal section and having the opposite end detachably connected to a second member extending upwardly from the base section.

Still another object of thepresent invention is to provide a support in the base for radioreceiving apparatus adapted to be removably secured to the pedestal section by means of the two members and associated coupling referred to in the preceding paragraph.

Another feature of this invention is to provide a pair of relatively rotatable telescopically engaging tubes supported on the second member for rotation about the axis of the latter and having the lower ends respectively connected to parts of the radio receiving apparatus requiring adjustment.

A further object of this invention is to provide a pair of control discs supported one above the other beneath the lower edge of the inverted cup-shapedshell part for rotation independently of each other about the axis of the second member and respectively connected to the upper ends of the tubes for actuating the latter.

Still another feature of this invention. is to provide a spacer between the coupling and support for the radio receiving apparatus in the base section for relieving the tubes from the clamping stresses exerted by the members and associated coupling.

In addition to the foregoing, the present invention contemplates an indicating band housed by the shell part in registration with a window in the side wall of the shell part and rotatable as a unit with one of the aforesaid control discs.

A still further feature of the present invention is to provide a construction wherein the control discs are supportedbetween adjacent ends of a two-part shell and wherein the shell is clamped between the adjacent ends of axially spaced pedestal sections by relatively simple means extending upwardly from the base section through the lowermost pedestal sectioninto the shell.

The foregoing as well as other objects will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure l is a side elevational view of a combined lamp and radio receiving set embodying the present invention;

Figure 2 is a view similar to Figure 1 having certain parts broken away for the sake of clearness;

Figure 3 is a sectional 3+3 of Figure 2;

Figure 4 is a side elevational view of a slightly modified form of construction; and

Figure 5 is a vertical sectional view of the construction shown in Figure 4.

In Figures 1 to 3, inclusive, I have illustrated an article of furniture in the form of a table lamp I0 having a base section II and having a pedestal sectionlfl. The pedestal section l2 supports a head 13 at the upper end thereof and the head l3 carries a shade I4 which may be of any specified shape. Upon reference to Figure 2, it will be noted that a two-part shell l5is interposed betweenthe lower end of the pedestal l2 and the base I I. As will be more fully hereinafter described, the upper part It of the shell is clamped to the lower end of the pedestal I2 and thelower part I! of the shell is secured to the base'section II.

It will also be observed from Figure 2 that a complete radio receiving set is housed in the lamp in such a manner as to be practically concealed from view. The radio receiving set emview taken on the line bodies a speaker unit [8 of suitable construction housed in an enlargement I!) at the upper end of the head 13 and is further provided with an audio transformer 20 supported in the reduced portion of the head l3 below thespeaker unit. The enlarged portion of the head also forms a support for the rectifier and audio frequency tubes 2| and 22 respectively. The illuminating plane of the pinions 42.

lamps 23 are also mounted on the enlarged portion IQ of the head l3 between the tubes 2| and 22.

The remaining parts of the radio receiving set are supported in the base section II of the lamp and are electrically connected to the parts in the head l3 by suitable electrical conductors extending upwardly through the pedestal I21 into the head It. It may be pointed out at this time that the electrical connectionsbetween the parts of the radio receiving circuit in the base section and the parts in the head l3 are detachable in order to facilitate assembly and disassembly of the lamp. For accomplishing this result, a conventional detachable plug and socket assembly 24 is suitably supported in the head l3.

Among the parts of the radio receiving set housed by the base section II are variable condensers 25 and a volume control rheostat 25 also embodying the usual off and on switch. The

condensers are distributed in the base section II in concentric relation to the vertical axis of the lamp and, in the present instance, three variable condensers are provided. These condensers are electrically connected in series and are mounted upon a support 21 housed in the base section II.

The support 21 comprises a top plate 28 having a bushing 29 concentrically arranged with respect to the vertical axis of the lamp and having fins 33 extending radially outwardly from the bushing beyond the periphery of the plate 28. The fins form supports for parts of the radio receiving circuit including the electronic discharge tubes 2| and the lower edges of the'fins are detachably secured to a base plate 32 by means of screws 33. The base plate 32 forms the bottom wall of the base section H and is adapted to fit into the lower end of a suitable cover 34 for the base section. The top edges of the fins are provided with brackets 35 adapted' to be removably secured to the lower end of the bottom shell part ll by means of the screws 36 and the cover 34 is centrally apertured to receive the lower end of the shell part ll. The construction is such that the portions of the cover 34 surrounding the central opening overlap the screws 36 and conceal the latter.

Each variable condenser 25 is carried by a U-shaped bracket 3-! and comprises the usual stator plates 38 and rotor plates 39. The stator plates 38 are secured to the base portion of the bracket in vertical spaced relationship and the cooperating rotor plates 39 are secured to a vertical shaft 40 having the opposite ends journaled in bearings supported on the legs of the U-shaped bracket. The brackets 37 are secured to the plate 28 in spaced relationship around the vertical axis of the lamprand the peripheral portion of the plate is formed with radially inwardly extending slots 4! for receiving the upper ends of the shafts 40. The axis of the condenser shafts 49 are concentrically disposed with respect to the vertical axis of the lamp and a pinion 42 is secured to the upper end of each condenser shaft 40. The rheostat 25 is also supported on the plate 28 and is provided with a vertical shaft extending upwardly through the plate beyond the The rheostat is positioned on the plate 28 in oiT-set relationship to the vertical axis of the lamp and the upper end of the operating shaft thereof is also provided with a pinion 33.

Extending upwardly through the bushing 29 on the support 21 is a tubular member 44 having a head 45 on the lower end thereof adapted to abut the lower end of the bushing 29. The upper end of the tubular member 44 extends into the upper part It of the shell l5 and is threaded for engagement with the lower end of a coupling 46. The upper end of the coupling 46 abuts the inner surface of the top wall of the shell part it and threadedly engages the lower end of a second tubular member 41. The second tubular member extends upwardly through the pedestal l2 and threadedly engages the lower end of a spacer 48 having an annular recess 49 in the lower end forming a seat for the upper end of the pedestal l2. The upper end of the spacer 48 is threaded on the lower end of the head It by means of a ring 49 forming a part of the spacer. The above construction is such that rotation of the coupling 46 relative to the tubular member 41 in one direction clamps the top wall of the upper shell section It to the lower end of the pedestal section I 2.

Referring again to Figure 2 of the drawings, it will be noted that the support 21 is held in assembled relation in the base section H by means of a spacer 50 mounted on the tubular member 44 with the upper end abutting the lower end of the coupling 46 and with the lower end engaging a washer 5| which, in turn, is seated on the top wall 28 of the support 21. As a result, rotation of the tubular member 44 in a direction to thread the same into the coupling 46 clamps the support 21 between the lower end of the sleeve 50 and the head 45 on the member 44.

Upon reference to Figure 2, it will be noted that a pair of relatively rotatable telescopically engaging tubes 52 and 53 are mounted on the spacing sleeve 50 for relative rotation about the vertical axis of the lamp. The lower end of the sleeve 52 is secured to a central driving gear 54 adapted to mesh with the pinions 42 for adjusting the variable condensers 25 simultaneously. The lower end of the tube 53 is connected to a pinion 55 which, in turn, is adapted to mesh with the pinion 43 for operating the combined rheostat and off and on switch 26.

A pair of control discs 56 and 5'! are supported in the space between the adjacent ends of the shell parts for rotation about the vertical axis of the lamp and have a diameter greater than the diameter of the shell I5 to provide for selectively rotating the control discs. The top control disc 55 is secured to the upper end of the tube 52 and the bottom control disc 51 is secured to the upper end of the tube 53. The arrangement is such that the top control disc 56 operates the variable condensers to tune the radio receiving circuit and the bottom control disc 5'! operates the oif and on switch as well as the volume control rheostat. It is important to note at this time that the spacing sleeve 55'relieves the tubes 52 and 53 from any clamping stresses resulting from securing the several parts together by the means previously described. As a result, unrestricted movement of the control discs may be had at all times regardless of the clamping pressure exerted by the securing means.

In the present instance, an indicator band 58 is secured to the tuning disc 56 and extends upwardly from the disc into the shell part IS. The indicia on the indicating band 56 is visible through the shell l5 by forming an opening 59 in one side wall of the shell opposite the indicating band.

In Figures 4 and 5, I have illustrated a floor lamp having the several parts of a radio receivaerator ing set embodied therein. It will be observed particularly from Figure that the principal difference between the floor lamp and the table lamp previously described is that the former comprises two axially aligned'pedestal sections 60 and BI. The top pedestal section 60 supports a speaker unit and shade assembly identical in construction to the speaker unit and shade assemblydescribed in connection with the first embodiment of this invention. The lower end.

of the bottom pedestal section is supported on a base preferably of the same construction as the base previously described. However, in the embodiment of the invention shown in Figures 4 and 5, the two-part shell [5' is located between the adjacent ends of the pedestal sections. The upper part It is positioned in abutting engagement with the lower end of the top pedestal section 60 and the lower part I1 is positioned in end of the coupling 46 threadedly engages the upper end of a tube M which is longer than the tube 44, previously described, but is anchored to the support for the radio receiving apparatus housed by the base in substantially the same manner as described in connection with the table r lamp shown in Figures 1 to 3, inclusive.

A spacing s1eeVe 50' is mounted on the tubular member 44' with the upper end abutting the lower end of the coupling 46 and with the lower end abutting the support for the radio receiving apparatus in the base in the same manner as thesleeve 50 defined in connection with the table lamp construction. A pair of tubes 52 and 53 are relatively rotatably mounted on the spacing sleeve 50' and extend from the shell downwardly through the pedestal section 6| into the base. As in the first described form of the invention, the inner tube 52' is operatively connected to the condensers of the radio receiving apparatus for simultaneously adjusting the latter and the outer tube 53 is operatively connected to the combined rheostat and off and onswitch. The upper end of the tube 52' extends beyond the corresponding end of the tube 53 and is secured to a control disc 56' between the adjacent ends of the shell parts. The upper end of. the tube 53' is secured to a similar control disc '51 located directly beneath the control disc 56' and having the periphery also extending between the adjacent ends of the shell parts. It follows, therefore, that the radio parts in the base are controlled in the same manner as described in connection with the table lamp illustrated in Figures 1 to 3, inclusive.

The upper end of the bottom pedestal section \is closed by a cap 63 centrally apertured to receive the outer tube 53' and forms a seat for the lower part ll of the shell IS. The bottom wall of the shell I5 is also centrally apertured to permit the passage of the outer tube 53 and associated parts therethrough. If desired, the

bottom Wall of the shell ll' may be secured at circumferentially spaced points to the cap 63 by suitablescrews 64 which are accessible through the upper end of the shell part ll".

will also be noted that my improved construction not only permits the several parts to be readily assembled but, also, renders it possible to expediently disassemble the lamp to permit'servicing of the radio receiving apparatus.
