13 Claims.

This invention relates to a combined article of furniture and radio receiving set.

More particularly, this invention contemplates an improved floor lamp having various instrumentalities of a radio receiver distributed in several parts of the lamp in such a unique manner that the dimensions or proportions of standard fioor lamp designs need not be materially altered v to accommodate the receiver and the presence of the latter is not readily apparent upon viewing the lamp.

Another advantageous feature of this inve tion resides in the provision of a combined floor lamp and radio receiving set wherein the several parts of the radio receiver, including the variable condensers, are grouped together to form a chassis unit assembly in the pedestal of the lam-p substantially midway between the base and shade of the lamp.

Another object of this invention resides in the provision of a combined floor lamp and radio re ceivingset wherein the pedestal of the lamp construction is formed of two sections and wherein the chassis unit assembly of the radio receiving set is interposed between adjacent ends of the sections.

Still another advantageous feature of this invention consists in the provision of a construction of the type set forth in the preceding paragraph wherein the chassis unit of the radio receiving apparatus is detachably secured to the upper end of the lower section of the pedestal and wherein the upper section of the pedestal is removably secured to the chassis unit.

Still another object of this invention resides in mounting a loud speaker unit in either or both the base section of the lamp or in the intermediate section containing the chassis unit and also consists in mounting a tuning control element for the variable condensers on the chassis unit independently of the upper section of the pedestal. As a result, the upper section of the pedestal may be removed without interfering with the performance of the radio receiving set.

A still further object of this invention consists in the provision of a radio receiving chassis unit assembly embodying a combined volume control rheostat and on-off switch in addition to the variable condensers previously mentioned.

Still another feature of this invention resides in rotatably supporting a pair of tuning dial members on the chassis unit beneath the lower end of the upper section of the pedestal for rotation independently of each other about the axis of the pedestal and respectively operatively connected to the variable condensers and rheostat for actuating the latter.

A still further advantageous feature of the present invention resides in the provision of a construction wherein the loud speaker of the radio receiving set is embodied in the intermediate section of the lamp constructionin compact relationship to the chassis unit and wherein the power transformer, rectifier, and amplifier tubes are housed in the base of the lamp construction.

In addition to the foregoing, the present invention contemplates a combined lamp and radio receiving set wherein the upper section of the pedestal forms a support for a shade unit embodying a loud speaker assembly which may be an addition to the loud speaker assembly previously mentioned.

With the foregoing, as well as other objects in view, the invention resides in the novel construction of the parts which not only lend themselves to economical manufacture but, in'addition, permits the same tobe readily assembled or disassembled 'for servicing. This construction will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 8 is a fragmentary sectional View illustrating a slightly modified form of construction; I

Figure 9 is a wiringdiagram of the embodiment shown in Figure 3.

Referring now more'in detail to the drawings,

it W111 be noted that I' have-illustrated in Figure 1 a combined lamp and radio receiving set comprising a base section I9, a shade section II, and an intermediate section I2 supported substantially midway between the shade and base sections. In addition, the lamp construction is provided with a pedestal I3 comprising a pair of aligned sections I4 and I5 in the form of tubes. The intermediate section I2 is supported on the upper end of the bottom section I4 of the pedestal and the lower end of the latter is removably secured to the base It of the lamp. The shade section II of the lamp is secured to the upper end of the top section I5 of the pedestal and the lower end of this section is detachably secured en the intermediate section I2 of the lamp.

The base I!) of the lamp is provided with a bottom wall It in the form of a disc having an opening I! through the center thereof and having the periphery detachably secured to an annular appearance ring It by means of the screws I9. The appearance ring I8 is removably secured to a spider 23 positioned in the base It] at'the upper end of the latter. Upon reference to Figure 5, it will be noted that the arms 2| of the spider extend radially outwardly to a point adjacent the side walls of the base and are secured to the appearance ring I8 by means of spacers 22.

The parts within the base It are concealed by a cover 23 having the lower end seated against an annular shoulder formed on the appearance ring I8 and having the upper end bearing on the top of the spider 20. The upper wall of the cover 23 is formed with an enlarged opening through the center thereof for receiving a ring 24 which, in turn, is secured to the spider by means of the fastener elements 25. The periphery of the ring 24 is threaded for receiving a nut 26 which serves to clamp the cover against the spider 29.

In the specific embodiment of the invention illustrated herein, the parts of the wiring diagram enclosed by th line 2'! in Figure 6 are located in the base I0 and are secured in any suitable manner to the bottom wall It of the base. Among the parts secured to the bottom wall I6 are the powertransformer 28, amplifier tube 23, rectifier tube 30, filter condensers 3i, and A. F. output transformer 32. These parts are electrically connected to a socket 33 having a detachable plug 34 which, in turn, is electrically connected to the radio receiving parts in another section of the lamp; The arrangement is such that the instrumentalities of the radio receiving set in the base may be removed as a unit with the bottom wall I6 of the base upon disengaging the plug 34 from the socket 33.

The lower end of the bottom section M of the pedestal is secured to a fixture 35 which, in turn, is secured to the top of the ring 24 by means of the fastener elements 25. The upper end of the section I 4 is fashioned to form a seat for engagement with the lower end of the intermediate section I2 of the lamp and is removably secured to the latter by means of a tie bolt 31. The tie bolt 31 extends upwardly through a central opening formed in the spider and projects through the tube forming the lower section I4 'of the pedestal. The tie bolt is provided with a head 38 at the lower end having a slot therein adapted to be engaged with a screw driver or other suitabl implement insertable through the opening I! in the bottom wall of the base.

The intermediate section I2 of the lamp comprises a casing 39 having a bottom wall 46 provided with a depending reduced annular hub portion 4! adapted to have a seating engagement with the upper end of th lower section I4 of the pedestal. The top of the casing 39 is provided with a removable top wall 42 in the form of a disc having the periphery seated upon an annular shoulder 43 extending inwardly from the side Wall 44 of the casing and having a relatively large opening 45 through the center thereof. Secured to the portion of the top wall 42 surrounding the opening 45 is a ring 46 having threads on the periphery thereof for detachably securing a disc 41 in seating relationship with the top wall 42 of the casing. The disc 41 forms a table top and is serviceable to support articles of different nature on the lamp.

The top wall 42 of th casing 39 is removably held in place by means of a spider 48 having a hub portion 49 extending into the hub portion 4| of the casing and threadedly engaged by the upper end of the tie bolt 31. In addition, the spider is provided with radially outwardly extending arms at having vertically upwardly projecting extensions 5| adjacent the side walls of the casing and detachably secured to th top wall 42 by means of the fastener elements 52. The construction is such that the tie bolt 31 cooperates with the spider 48 to secure the casing 39 and removable top Wall of the latter to the upper end of the bottom section I4 of the pedestal.

Suspended from the top wall 42 of the casing 39 is a plate 53 having generally radially extending vertical partitions 54 projecting upwardly from the top surface thereof and provided with lugs 55 at the outer ends which are removably secured to the underside of the top wall 42 by means of the fastener elements 56. Secured to the central portion of the plate 53 is a casting 51 having a tubular portion 58 extending upwardly through the ring 45 with its axis concentric with the extended axis of the pedestal sections.

According to the present invention, the various parts of the radio receiving circuit surrounded by the line 59 in the diagram shown in Figure 6 are carried by the plate 53 and form a chassis unit assembly. Among the parts carried by the plate 53 are three variable condensers 60 having the usual stator plates GI and the rotor plates 62. The shafts 63, upon which therotor plates of the condensers are respectively secured, extend vertically and are spaced from each other in concentric relationship to the axis of the tube 58. Each shaft 63 has a pinion 64 secured to the upper end thereof and these pinions mesh with a central driving gear 65 mounted on the casting 51 for rotation about the axis of the tubular portion 58 of the casting.

The gear 65 is rotated from a position above the table top 41 by means of a tuning dial 66 secured to the upper end of a bushing 61 which, in turn, is rotatably sleeved on the tubular portion 58 of the casting. The lower end of the bushing 6'! is secured to a gear 69 which, in turn, meshes with a pinion III rotatably mounted on a vertical stub shaft II suitably supported on the casting 51. A pinion I2 of relatively small diameter is also rotatably mounted on the shaft ll beneath the pinion I0 and meshes with one of the condenser gears 64 which also meshes with the center gear 35. Inasmuch as the remaining condenser gears 64 also mesh with the center gear 65, it follows that the condenser gears 64 are simultaneously adjusted upon rotation of the dial 66. From the foregoing, it will be seen that the gearing between the dial 66 and the rotors of" the condensers is of the speed reducing type so that the condenser rotors may be accurately tuned from the dial.

In addition, a combined volume control rheostat and off-on switch 14 are among the parts of the radio receiving set carried by the plate 53. Upon reference to Figure 2, it will be noted that the rheostat 14 is provided with a downwardly extending shaft 15 operatively connected to the lower end of a vertical shaft 16 through the medium of gearing 11. The shaft 16 is journalled in the casting 51 and is provided with a pinion 18 at the upper end thereof adapted to mesh with an internal gear 19 secured to a second dial control disc 88. The control disc 80 is positioned directly above the dial 66 and is supported for independent rotation about the axis of the tubular portion 58 of the casting.

In Figure 2 of the drawings,-I have illustrated a speaker unit 8! as also supported in the casing 39. The speaker cone 82 faces upwardly and is detachably secured to the underside of the plate 53 by means of the fastener elements 83. The hub portion 84 of the speaker extends into the hub portion 49 of the spider 48. When installing the speaker in the position mentioned aforesaid, the bottom wall 40 and the side wall 44 of the casing are perforated, as at 85, to permit the passage of sound.

It follows from the above that the chassis unit of the radio receiving set and the speaker form a compact assembly capable of being removed as a unit. Attention is called to the fact at this time that those parts of the radio receiving set in the casing 39 to be connected to the parts in the base are electrically connected to a plug 86 located in the upper end of the bottom section I4 of the pedestal. The plug 86, of course, detachably engages a socket 81 which is electrically connected to the proper parts in the base I!) of the lamp. With the above construction, it will be noted that disengagement of the tie bolt 31 from the hub 49 of the spider 48 permits the casing 39 and chassis unit, including the speaker 8|, to be removed as an assembly.

The upper section l5 of the pedestal I3 has a ring 89 secured to the lower end thereof by means of the fastener elements 98. The lower end of the ring is counterbored and threaded for connection with the upper end of the tubular portion 58 on the casting 51. The arrangement is such that the section I5, together with the lamp shade assembly supported thereby, may be readily removed from the intermediate section l2, if desired. Removal of the section l5 of the pedestal and the associated lamp shade assembly H does not interfere with the operation of the radio receiving apparatus, previously described, and, therefore, the construction may be converted from a lamp to a simple radio table or stand. In the event the section I5 of the pedestal is dispensed with, it will, of course, be advantageous to provide a finishing member on the upper end of the tube 58. Such a member is shown in Figure 7 by the reference character 9!.

As shown in Figures 3 and 9, the upper end of the pedestal isthreaded for engagement with a tubular fixture 93 which, in turn, supports the lamp shade 94 and the usual illuminating means 95. In the present instance, the tubular fixture 93 also supports a speaker assembly 96. This assembly includes a power transformer 91, a rectifier tube 98, an amplifier tube 99,-and a speaker cone I98. These elements are electrically conthe tube 58 and adapted to 'detachably engage a cooperating socket I02 which, in turn, is electrically connected to the required radio receiving parts in the chassis unit assembly, previously described as supported in the casing 39. The manner. in' which this connection may be accomplished is shown by the dotted lines in Figures 6 nected to a plug l0l located in the upper end of and 9. It will, of course, be understood that the speaker assembly 96 in the shade unit may either be used in addition to the speaker assembly 9| in the casing 39 or may be substituted for the latter speaker. In the event it is substituted for the speaker assembly 8|, the power unit in the base may also be eliminated.

In Figure 8 of the drawings, I have shown a slight. modification wherein the top wall 42 of the casing 39 is removably secured to the annular shoulder ,43' at circumferentially spaced points by means'of fastener elements I85. The construction is such as to permit the chassis unit assembly, including the speaker, to be detached from the casing by removing the top wall 42'. It will, of course, be understood that the cover disc 41 must be removed before access can be obtained to the fastener elements I85. This cover disc is threadedly mounted on the ring 4% so as to permit the same to be readily removed when desired. It may also be pointed out that in this embodiment of the invention, the spider 48 may be entirely eliminated, if desired. In the event the'spider 48 is eliminated, theupper end of the tie bolt 31' may be secured directly to the lower end of the'hub portion 4| of the casing 39.

In the event the embodiment shown in Figure 8 is used, it is desirable to provide a second detachable plug connection between the parts of the radio circuit in the base and the parts of the radio circuit in the chassis unit. A detachable plug for this purpose is shown in Figure 8 as having a socket. 81' electrically connected to the plug 86 in the upper end of the pedestal section I 4 and as having a plug 86 electrically connected to the parts of the radio receiving circuit in the chassis unit. The detachable plug 86' and socket 81' are located in such a position in the casing 39 to be readily accessible upon 1 removing the top wall 42' of the casing.

Thus, from the foregoing, it will be observed that I have provided a novel construction of combined article of furniture and radio receiving apparatus. It will also be noted that the construction shown is such as to permit its optional use as a radio table or as a floor lamp. In either case, the parts of the radio receiving set are compactly distributed in the several sections of the article of furniture to not only afford efficient operation of the radio circuit, but to also provide for obtaining a design having a neat and pleasing, appearance. In addition, it will be observed that the construction is such as to permit readily assembling and removing the parts of the radio receiving set.
