9- Claims.

This invention relates to combination radio and phonographic units, and more particularly to units employing an automatic record changer.

Automatic record changers have been employed in connection with phonographs for a number of years. More recently, they have been used quite widely in combination radio and phonograph units. In view of the fact that automatic record changers involve considerable op-- crating mechanism, they are more or less bulky in size. These automatic record changers in combination radio and phonograph units are usually disposed in a relatively deep well in the top of the radio cabinet which is accessible by opening the lid of the radio cabinet. In other instances they are mounted substantially on top of the radio cabinet but beneath a lid having a relatively deep skirt or side wall which conceals the unit when not in use. These arrangements for the most part have either been unsightly in appearance or else not readily accessible to the person who wishes to play the machine.

It is an object of the present invention to provide a novel radio phonograph construction in which the automatic record changer and phonograph unit may be quickly and easily brought to an accessible position, but which may be retracted to a concealed position when not in use.

It is a further object of the present invention to provide a novel radiophonograph carriage and cabinet in which the phonograph unit is mounted on a movable carriage which. may be partially withdrawn from the radio cabinet when the phonograph is to be played.

Another object of the present invention is to provide a novel cabinet construction for combination radio and'phonograph units in which the phonograph unit is mounted on a slidable carriage which is partially withdrawn from the radio cabinet when one or more doors on the front of the cabinet are opened.

Another and still further object of the present invention is to provide a novel supporting and mounting structure for the turntable and associated mechanism of a phonograph or other record player.

The novel features which I believe to be characteri'stic of my invention are set forth in particularity in the appended claims. My inven-= tion itself, however, both as to its organization and manner of construction, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings, in which:

Figure l is a front perspective view of a combination radio and phonograph unit;

Figure 2 is a rear elevational view of the combination radio and phonograph unit shown 1 Figure 1;

Figure 3 is a plan view of the phonograph supporting carriage in its retracted position within the radio cabinet;

Figure 4 is a view similar to Figure 3 but showing the phonograph supporting carriage in its withdrawn position; and,

Figure 5 is a vertical sectional view along the line VV of Figure 3.

A combination radio and phonograph unit as shown in Figures 1 and 2 of the drawings includes a cabinet II which houses an automatic phonograph and record changer unit l2 and a radio l3. The radio [3 is mounted in the upper portion of the cabinet H and is equipped with the usual'control knobs M, a dial l5, and a set of push button controls I6. The phonograph and record changer unit I2 is carried below the radio unit 13 partially on and partially within a housing H which is arranged to slide out of the cabinet II when the two cabinet door l8 are opened. A power cable I9 to operate the mechanism of the phonograph unit I! extends from the radio I3 as is shown in Figure 2. The pick up head 20 of the arm M is electrically connected to the radio set in the conventional manner through a cable 22.

The phonograph-unit l2 as shown includes a turntable 23 having a center spindle 24 over which a stack of records are placed and seated on the automatic record changer arms 25.

Referring now particularly to Figures 3, 4 and 5 of the drawings, it will be seen that the housing or carriage ll of the phonograph unit I2 is provided with a pair of rollers 26 on each side thereof. The housing or carriage I! as shown contains the principle operating mecha-- nism of the phonograph and record changer unit.

The rollers 26 ride in a 'pair of metal channels 21 on opposite sides of the casing or carriage H which in turn are carried in wooden crossarms 28 which are channeled out to receive the channel bars 21. These wooden bars 28. are secured to the crossbar 29 at the rear of the cabinet II and to the crosspiece 30 at the front of the cabinet. Reinforcing blocks 3| are preferably secured to the rear of the bars 28 and the crossbar 29 in the manner as shown in Figures 3, 4 and 5.

The rollers 26 riding in the metal channel bars 21 provide the necessary support for the casing or carriage I! of the phonograph and record changer unit l2.

Two guide roller elements 32 depending from the casing I! ride in a channel bar 33 to prevent lateral shifting of the casing IT. The channel bar 33 is mounted on the rear crossbar 29 and the front crossbar 30 and is suitably secured thereto in any convenient manner.

The doors IE on the front of the cabinet II are mounted on cabinet hinges 34 and are provided with knobs or handles 35, which enables them to be swung open at will. Secured to each door 18 is a rearwardly projecting metal plate 36 which is mounted on the rear face of each door. This rearwardly projecting metal plate 36 is equipped with an upwardly projecting roller element 31 which is free to rotate on the plate 36. In the bottom of the casing i! there are formed two slots 38 which extend at a slight angle to the front face of the casing H. The roller element 31 on the plate 36 of the doors l8 extend up and ride in these slots 38. From an examination of Figures 3 and, 4 of the drawings it will at once be apparent that as the doors l8 are swung open the casing I! will be partially withdrawn from within the cabinet ll. Suitable stop means (not shown) are provided to limit the outward movement of the casing l1 and to prevent the front rollers 26 from dropping out of their respective channel tracks 21.

As is clearly shown in Figure l, the phonograph and record changer unit I2 is withdrawn to a sufficient extent by the opening of the doors I 8 to render the turntable readily accessible by the person wishing to operate the machine. In this position a stack of records (not shown) may be placed over the center spindle 24 on the supporting arms 25, and the doors l8 may then be closed and the phonograph unit placed in operation in conjunction with the radio l3.

The particular typeof arrangement which has been illustrated and described has been found 1 to be particularly satisfactory since the phonograph and record changer unit may be disposed in the interior of the cabinet II in a concealed position during ordinary use of the radio and during actual playing of the phonograph itself, and yet at the same time it may be readily and quickly moved out to an accessible position by simply opening the front doors of the cabinet.

While I have shown a particular embodiment of my invention, it will, of course, be understood that Ido not wish to be limited thereto, since many modifications may be made, and I therefore contemplate by the appended claims to cover all such modifications as fall within the true spirit and scope of my invention.

I claim as my invention:
