10 Claims.

This invention relates generally to radio receiving apparatus and refers more particularly to a lamp and/or smoking set embodying the several parts of the radio receiver.

One of the principal objects of this invention is to provide a lamp or smoking set construction with a radio receiving set having the parts forming the receiver proper combined in a single chassis assembly supported in the base of the construction in such a manner as to permit the chassis to be readily removed from and installed in the base as a unit. 7 V

Another advantageous feature of the present invention consists in detachably securing the chassis of the radioreceiving set in the base of the construction by means rendering it possible to remove the chassis without disassembling or interfering with the parts of the lamp or smoking set.

Still another advantageous feature of this in vention resides in the provision of a lamp or smoking set of the character set forth embodying a pedestal having a tuning unit carriedthereby at a convenient point above the base and equipped with means for actuating the several 'instrumentalities of the'radio receiving set requiring adjustment.

A further object of the present invention consists inoperativ'ely connecting certain of the controls of the tuning unit to the controllable parts means for eliminating back lash in the gearing.

With the above, as well as other objects in view,

the invention resides in the novel construction of i stantially on the plane indicated by the line 3-3 of Figure 1; I

Figure 4 is a cross sectional view taken substantially on the plane indicated by the line 4-4 of Figure 1; a

Figure 5 is a cross sectional view taken sub stantially on the plane indicated by the line 5- of Figure 1; and

Figure 6 is a fragmentary sectional view illustrating a slightly modified form of invention.

For the purpose of illustrating the present invention, I have selected a floor lamp construction having a base Ill and a lamp shade assembly II supported from the base by means of a pedestal I2. Inthe present instance, the base I is substantially drum-shaped having an annular flange l3 forming the side wall of thebase and having a web l4 forming the top wall of the base. The web I4 is centrally apertured, as at l5 and is detachably secured to the bottom of the pedestal [2. In detail, a hub I6 is threaded upon the lower end of the pedestal l2 and is provided with a radially outwardly extending flange I! at the lower end thereof for attachment to the web I 4 by means of fastener elements [8. Upon reference to Figure 1, it will be noted that the hub 16 and fastener elements l8 are concealed by means of a cover plate l9 having a threaded engagement with the upper end of the hub.

Housed within the drum-shaped base 10 is a chassis 2B of a suitable radio receiving "set having a casing 2| adapted to enclosethe severalinstrumentalities of the radio receiver including the variable condensers 22. As a matter of fact, the chassis preferably, although not necessarily, contains all of the parts of the radio receiving apparatus except the rectifier and audio tubes which are housed in the shade assembly I I of'the lamp with the loud speaker unit. I prefer to locate the rectifier" and amplifier tubes in the shade of the lamp due to the fact that in this position the excessive'heat radiated by these tubes may be more readily dissipated without the dan- 'ger of overheating the insulation employed in association with the parts of the radio receiver proper.

The chassis 20 is secured to a spider 23 housed in the base Ill above the chassis and having a hub portion 24 provided with an opening 25 therethe periphery of the base plate 21 of the chassis by means of the spacers 28. In the present instance, the fastening means 18 is shown as comprising studs 29 having the lower ends anchored in the hub of the spider and having the upper ends extending through aligned openings formed in the central portion of the web l4 and the peripheral portion of the radial hub flange ll. Suitable nuts .30 are threaded upon the extreme upper ends of the studs and serve to clamp both the spider and base I to the hub it. As a result, the chassis assembly 20 with the spider 23 may be readily removed as a unit from the interior of the drum-shaped base section ID by merely removing the cover [9 from the hub I 6 and disengaging the clamping nuts 39 from the studs 29.

Removing the chassis 20 in the above manner, however, requires disassembling the base In from the pedestal l2 and, while this may not be objectionable, nevertheless, in some cases it may prove more advantageous to remove the chassis unit without disassembling any of the parts of the lamp. This may be accomplished with the above construction by merely removing the screws 28 which are shown in Figure 1 as operable to secure the base plate 21 of the chassis unit to the spacers 28. These screws are the only fastening means holding the chassis unit in assembled relation with the spider and, accordingly, removal of these screws permits the chassis unit to be detached from the spider without molesting any part of the lamp structure. V

It wi-ll, of course, be understood that certain of the instrumentalities in the chassis assembly ZO mustbe electrically connected to the speaker unit in the lamp shade ll bymeans of electrical conductors. and that some provision must be 'made for disconnecting these conductors when it is desired to remove the chassis from the base H]. In detail, a ring 3| of dielectric material is secured to the top wall of the chassis unit and is provided with. a plurality of circumferentially spaced sockets 32 respectively electrically connected to the several instrumentalities in the chassis 20 of the radio'receiving set that it is desired to electrically connect to the loud speaker unit in the lamp shade ll. Positioned above the ring 3|. in vertical spaced relation thereto is a similar ring 33 secured to the radial flange I! of the hub l6 and carrying plugs 34. The plugs 34 correspond in number to the number of sockets 32 in the ring 3! and are respectively connected to electrical conductors 35 which extend upwardly through the pedestal l2 to the speaker assembly in the lamp shade H. The dimension of the plugs is predetermined to permit engagement of the-lower ends of the same into the sockets 32 and, when engagedwiththe sockets, the electrical conduct'ors .35 form a continuation of the electrical conductors connected to the sockets.

As will be more fully hereinafter set forth,

"provision is made for Varying the capacities of the condensers 22 in the radio receiving chassis 2| and for controlling the volume of the set by atuning dial unit 36 supported on the pedestal l2. at a point substantially above the base H]. Upon referenceto Figures 1 and 2, it will be noted'that the rotors of the several condensers 22 are simultaneously adjusted by means of gearing '31. comprising a .driving gear 38 supported on the chassis unitZD for rotation about the vertical axis of the pedestal l2 and meshing with suitable pinions 39 having hub portions respectively secured to the rotor shafts of the condensers 22. The central driving gear 38 is rotated from the tuning dial 36 by means of a tubular shaft 40 supported in the pedestal l2 and having a coupling 4| secured to the lower end thereof for connection with the driving gear 38. As shown in Figure 2, a pair of diametrically opposed radially extending slots 42 is formed in the driving gear 38 for receiving the depending lugs 43 on the coupling 4|. As a result of this construction, the lower end of the shaft 40 is automatically disconnected from the driving gear 38 when the chassis assembly 20 is removed from within the base section I!) of the lamp.

In the present instance, the chassis assembly also includes the combined volume control and on-and-off switch 44. This switch is shown in Figure 1 as having an operating shaft 45 revoluble on the axis of the shaft 40 and having the upper end operatively connected to a shaft 41 through the medium of a coupling 48. The shaft 41 extends axially through the tubular shaft 40 and the coupling 48 at the lower end of the shaft is provided with depending lugs 49 adapted to engage the opposite ends of the pin 50 which extends transversely through the shaft 45. Thus, it will be seen that the coupling 48 not only provides for operating the device 44 but, in addition, automatically releases the latter device when the chassis unit 20 is removed from within the base section ll] of the lamp.

It follows from the foregoing, that the chassis unit 20, although containing parts adapted to be adjusted from a point on the pedestal l2, may be readily removed from the base section I0 of the lamp by merely disengaging the screws 28 from the studs 29. The chassis may then be transported to any convenient point for repair without the necessity of disassembling the lamp structure.

. The pedestal I2 is shown in Figure 1 as being formed of two vertically aligned tubular sections 5! and 52 having the same or different diameters depending upon the particular design of lamp construction desired. The adjacent ends of the sections are spaced vertically from each other and are interconnected by means of the tuning dial unit 35. In detail, the unit 36 comprises a housing 53 having-a hub portion 54 at the lower end threadedly engaging the upper end of the section 5| and having an enlarged tubular portion 55 at the upper end adapted to be secured to the periphery of a flange 56 extending radially outwardly from the lower end of the section 52.

The upper end of the tubular shaft 40 terminates in the housing 53 and is operatively connected to a ring 51 through the medium of reduction gearing 58. The arrangement is such that rotation of the ring 51 imparts a relatively slow rotative movement to the shaft 48 and effects a Vernier adjustment of the condensers 22 through the medium of the gearing 31. In detail, the ring 51 surrounds the reduced annular side wall 59 of the housing 53 and an internal gear 60 is formed integral with the ring 51 for intermeshing engagement with a pinion 6| mounted one carrier 62. The pinion 6| also meshes with a ring gear 63 surrounding the annular portion 59 of the housing and secured to the latter. Inasmuch as the housing 53 is prevented from rotation and the gear 63 is secured to the housing, it follows that rotation of the ring 5'! about the axis of the shaft 40 imparts a rotative movement to the carrier 62 at a relatively reduced speed. The carrier 62 is in the form of a ring surrounding the portion 59 of the housing and connected to the upper end of the shaft 48 by means of an arm 65 having the outer end suitably secured to the ring 62. The arm 65 projects inwardly of the ring 62 through a circumferentially extending slot 66 in the portion 59 of the housing and the inner end of the arm is provided with a hub 61 secured to the upper end of the shaft 48 by means of the set screw 68. The carrier 62 is supported on the top edge of a sleeve 69 surrounding the portion 59 of the housing in spaced relation thereto and supported at the lower edge on a ring I8 which is secured to the housing by means of the fastener elements II. The ring 51, on the other hand, is supported for rotation on the sleeve 69 between the carrier 82 .and an annular bearing I2 extending radially outwardly from the sleeve 69.

For the purpose of eliminating any error introduced by back lash in the gearing 58, the pinion 6| is mounted on the carrier for swinging movement in the plane of the gearing and the carrier 62 is normally urged in a direction transversely of the axis of the shaft 48 in a direction to yieldably clamp the pinion 6| against the ring gear 63. In detail, the pinion 6| is rotatably supported on one end of a link I3 having the opposite end pivotally connected to the ring 62 and a spring I4 is interposed between the sleeve 69 and annular side wall 59 diametrically opposite the pinion 6| for urging the ring 51 and pinion 6| toward the ring gear 63. The spring 14 is in the form of a bowed leaf spring having the opposite ends engaging the annular side wall 59 of the housing substantially diametrically opposite the pinion BI and having the intermediate portion engaged by an adjusting screw I threaded in the sleeve 69.

The ring 51 carries the wave band indicating strip II in a position so that the latter is visible through a window I8 formed in the central portion 19 of the surrounding ash receptacle 88. The ash receiving receptacle 80 may have any desired shape and is secured to the section 5| of the pedestal. It will, of course, be understood that this receptacle may be eliminated, if desired, without changing any of the essential parts of this invention.

The combined volume control and "on-and-off switch 44 is also actuated from the tuning unit 38. As shown in Figure 1, a ring 8| is rotatably supported on the outer wall of the enlarged portion 55 of the housing and has a series of teeth 82 on the inner surface thereof adapted to mesh with an idler gear 83 supported in the housing 53 for rotation in the plane of the ring 8|. The idler gear 83 also meshes with a gear 84 secured to the upper end of a shaft 41 so that rotation of the ring 8| effects an operation of the device 44 through the medium of the shaft 41. It will, of course, be understood that the annular side wall portion 55 of the housing 53 is circumferentially slotted to provide for extending the periphery of the idler gear 83 therethrough into mesh with the teeth 82 on the ring 8|.

The shade assembly of the lamp is supported on the upper end of the section 52 of the pedestal and comprises the illuminating means 98, in addition to the speaker unit 9|. The illuminating means is in the form of suitable electric light bulbs carried by the housing 92' which, in turn, is secured to the upper end of the section 52 of the pedestal. In accordance with conventional practice, the electric light bulbs are arranged in an electric circuit with an on-and-oif switch 93 supported in the housing 92 in the manner clearly shown in Figure 1. In the present instance, the switch is controlled from the dial assembly 38 by means of an arm 94 having the outer end projecting through a circumferentially extending slot in the enlarged annular side wall 55 of the housing 53 for convenient manipulation by the operator. The inner end of the arm 94 is operatively connected to the lower end of a shaft 95 supported in the section 52 of the pedestal and having the upper end operatively connected to a switch 93.

The speaker unit 9| includes the usual cone 96 supported within the lamp shade in operative relation to the sounding board 91 which forms the top of the shade. Also, the speaker unit is provided with a power pack comprising a transformer 98 supported within the housing 92 and electrically connected to theaudio and rectifier tubes 99 and I88, respectively. As previously stated, the power packis electrically connected to the plugs 34 in the base III by means of the conductors 35 and the plugs, in turn, are electric ally connected to the proper instrumentalities in the chassis by means of the sockets 32 positioned on the chassis for detachably receiving the plugs.

In cases where it is desired to incorporate a tone control in the radio receiving apparatus, the construction shown in Figure 6 may be provided. As shown in Figure 6-, the tone control I81 is supported in the housing 92 and is adjusted by means of a pinion I82 adapted to mesh with a ring gear I83 fixed to the inner surface of a cup-shaped casing |84. The casing I84 is of sufficient diameter to receive the lower end portion of the housing and is provided with a hub portion I at the bottom thereof apertured to receive the section 52 'of the pedestal. The hub portion I85 is secured to a tube I88 surrounding the section 52 of the pedestal and having the lower and secured to the hub I81 of a plate I88 which is arranged in overlapping relation to the radial flange 56 at the bottom of the section 52. It follows from the above that rotation of the plate I88 effects an adjustment of the tone'control device II.

From the foregoing, it will be observed that I have provided a unique lamp construction which permits incorporating the chassis of a radio receiving set in the base thereof in such a manner as to permit the chassis to be readily removed from and installed into the base as a unit without disassembling the lamp structure. It will also be noted that the invention provides an improved tuning dial assembly which is not only conveniently located on the pedestal of the lamp structure for accessibility, but which also embodies all of the controls required for successful operation of the radio receiver. In addition, it will be noted that the present invention also contemplates incorporating a smoking set in association with the pedestal without interfering with any of the parts of the lamp or radio receiving set.
