rfipresents a vertical section on the radio circuit is o the radio chamber, formed between the partition or shelf 3 already described, and the shelf 22 below, the front of said radio chamber being closed by the drop door 23, hinged at the points 24. Be-

,hind the drop door is the control panel 25,

of the coordinating unit, which is preferably ositioned at the rightof the radio chamer,as will be understood from Fi re 2, the left hand portion of the radio 0 amber 21 being The rig it hand coordinatingvunit, carried by the control panel 25, consists of the rheostat 27, having the control'knob 28 which controls the volume of electrically reproduced sounds of the phonograph. On the coordinating unit panel 25, there is also mounted the operating knob or handle, 29 of the switch or contacting device 59, which in its extreme positions controls the circuit of the phonograph or the radio. In the B5 resent construction, when the switch handle is thrown to the left, as seen in Figure 2, to theradio indicia 30, the ra'dio circuit is closed and the radio receiving 'set is functioning. When the switch handle 29 is 00 thrown to the right of the position seen in Figure 2, to the phonogra h indicia 31, n'and t e phone aph circuit is closed, set at the electrical p cmgraph reproducer is functioning; it being understood that the loud s eaker 11 is comcircuits, and the ma er of opening and closing the circuit 0 each being apparent mon to both the radiiurm the phonograph from the wiring diagram seenin Figure 9.

The lower compartment formed between the bottom 33 and the upper shelf 22, is divided by the central vertical partition 32, into the left and right hand compartments 34'and 35, adapted for the batteries 36 and v 37 and record albums 38. The compartments 34 and 35 are closed by the doors 39 and 40.

In the constructions seen in Figures 5 and d 6, I have shown the right hand top portion or-lid 41, hin ed at the points 42, and the loudspeaker esi ated as 43, is hinged at the points 44 to 't e under side of said lid.

which is adapted to stand vertical when the phonogra h or radio is functioning, said oud spe er being common to both, as in the construction already described. The left hand top portion 45, seen in Figure 5, isprefera lv stationa or fixed.

be The electrical'coordinatmgunit, mounted upon the anal 25, is com sed of the induction coil or transformer 50, havin the grimar coil 51 and a secondary cm 52. ne si e oftheprimary coil 51 is connected through suitable connections 53 to one of 2 the two binding posts or lug contacts 54 adapted to receive the lea '-W116S from thehonograph reproducer; the other of said inding osts or plug contacts 55 being connected irectly to one side of the storage provided with the radio panel 26. 75

The coordinating unit'includes t e multiple switch or contacting device 59, having the three stationary contacts 60, 61 and 62 and having the two movable spring contacts 63 and 64 which are moved in unison by an insulatin roller 65. carried by the handle 29 pivote at 66. The movable contact 63 is juxtaposed to said stationary contact 60, while the movable con.

The second stationary contact 61 is connecteddirectly to 'one side of the secondary windi 52 of said induction coil. 50 throu h a said secondary windin being connected dir'ectly to one 'of the and speaker binding i 17 'moving the handle 29 in the direction of the arrow 71, there will also be established.

posts or plu contacts 73, through a suitable connection 4. The second movable contact- 64 is connected directly to the second loud peaker binding post or lug contact 75 irough the connection 6. Thus, upon a complete electrical circuit through the loud speaker contacts or binding 7 3and 7 5 andthe secondary. winding 52,-thro'ugh said stationary andmovable contacts 61 and 64 respectively, thereby effecting an o rative electrical connection from the reco repro-a .ducer to the loud speaker, in the extrem right hand position of the handle 29.

' One of the bindingposts 77 to which the input line of a radio set is connected, is di- 7 ing post 73, through the connection78, while the second radio in ut bindin post 79 is conhectsd through t econnection 80 to the; stationary contact Thus, upon turning the handle in the direction of the arrow 81,

the movable spring contact 64 will engage,

and make. electrical contact, with the stationar contact 62, thereby connecting said secon' second loud spea er binding post 75, thereb radio input binding post with the o ratively connecting. the radio set wit i t e loud speaker; while the honograph reproducer is disconnected. bus, the contacting device 59 has the function of electrically connectingfin series with each other the record reprodu'cer, the source of electrical energy, the .rheostat and the primary winding of the transformer; as well as to connect in series with each other the loud speaker and the secondary winding of the transformer; of connecting in series, in the opposed extreme position of the handle 29,

the radio set and said loud speaker; and to maintain each of these. elements electrically disconnected, in the intermediate or neutral position of said handle. These functions are carried out by the vtwo opposed movable. spring contacts 63fand 64, which are constantly urged towards each other, by the resiliency thereof, and the separating roller 65 interposed between said spring members, as shown particularly in Figure 9.

By-my novel construction in a cabinet, as

shown particularly. in Figures 1 and 4, in mounting the cone type e relation to one of inner walls of the chamber 2, there is obtained a novel combination of cone'loud speaker and a tone chamber 2, one wall of which acts as a sound board for said loud speaker, while the other walls surrounding act-ass tone or resonat- "ing chamber, which directs and amplifies the of speaker in spaced sound emanatin 'from' said loud speaker.

The grill front oors ermit the sound to be projected out of sai tone or resonating .chamber, with the front thereof closed and with the loud speaker concealed.

It will be obviousthat the collocation of the radio panel 26, and the control panel 25, as shownin Figure 2, imparts a symmetrical, balanced andpleasing appearanceto the cabinetfront; and 'I' may if desired construct the radio 7 drawer, (as will. understood from Figure 4,) which contains the various coacting radio elements, assembled within said drawer ggnel 26 as the front of a,

as a unit, so thatto position the radio, it :s-

. only necessary to push in the drawer. In like manner, aswill be understood from Fig-' ures 2'-and 7 to .9, the principal control elements of the panel 25 are mounted directly thereon, so that on' the removal ofthe panel all the elements thereon or carried thereby .a're readil accessible. rectly connected to the loud speaker bind- It will apparent that only the single control member '29 is nry .in order to onographic reproduction, apd

ity to the control lever 29 enables all the manually operable parts to be compactly assembled in roximity to each other.

While I have shown the radio as being contained in the drawer, so that the coacting radio elements can be readily pushed into position or. withdrawn as a unit, it w1ll be. apparent that my invention is not confined to this precise construction, as any conventhe radio receiving set by the employment of the cone loud speaker 111 tional or standard form of radio receiving set may be employed.

It will further be understood that the disc records emplo ed may have the sound reprovarious elements, reproduced sounds of a.

maximum volume are produced from the disc record without the use of vacuum tubes,

and the control of the volume of saidsounds is instantly effected by the rheostat 27 and its adjuncts. By. my novel construction I am enabled to transmit any sounds or signals locally. reproduced from the SOUIld record having its grooves formed either mechanie cally or electrically, or I can, reproduce signals of any character, such as high frequency signals received from a distant station by the manual operation of the small lever 29. p

It will be apparent that by the elimination of the vacuum tubes or other amplifying means from the circuit leading to the electrically operated phonographic reproducer, both the expense and upkeecpof said vacuum tubes is entirely eliminate so that my device can-bc operated at "a minimum of expense. 3 4

It will be evident that the size, "shape. and contour of the cabinet may be varied according to requirements, but I, referxtoemploy asmall compact cabinet having substantially the contour shown, since the depth from front to rear need be only slightly in excess of the diameter of the turn-table 9, as will be apparent from Figures 4 and 6* By positioned above the turn-table 10, as will be seen from Figures 2 and. 4, a very compact structure is attained, and the overall'height of the cabinet is reduced to a minimum. The panels 26 and 25 are positioned so as to be readily accessible to a sitting operator, and

the reproduced sounds emanating from the loud-speaker are on about a level with the operators ear, when in a sitting position andtuning in the radio, as is evident.

It will now be apparent that I have devised a novel and useful construction of combined phonograph and radio and coordinating unit therefor, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, itis to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the-invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Lettcrs Patent is 1. A detachable phonogra h and radio coordinating unit of the c aracter stated, adapted to bepperatively interposed between an electricalfrecord reproducer, aradio receiving set, a loud speaker and a source of electrical energy, comprising a contacting device having tin/operating andle, a rheostat havin an operating knob and a'transformer; said rheostat and the primary winding of said transformer being connected in series with a corresponding pair of contacts in said contacting device, and the secondary winding of said transformer being in series with a second corresponding pair of contacts in said contacting device; said contactin device also having a set of contacts to which the output line of said radio set is adapted to be connected.
