This invention relates to novel television apparatus and more particularly to anovel cabinet type apparatus of this class wherein the picture reproducing device is normally disposed within and concealed by the cabinet, and is movable at will to an accessible or viewing position.
Picture reproducing devices such as cathode ray oscilloscopes of the type commonly used in home television apparatus comprise a tube having a long longitudinal axis and a viewing screen at one end in a plane perpendicular to said axis. Heretofore in receivers adapted for home use it has been necessary to provide a cabinet of extreme depth in order to provide for directviewing of the reproducing screen from the front of the cabinet. This is objectionable in that it materially detracts from the appearance and design capabilities of the cabinet. Further, with previously known arrangementsfor mounting the picture reproducer within a shallow cabinet formounting arrangement for the picture reproducing device of home television apparatus such that the device may be'normally concealed within a cabinet but may be'partially withdrawn therefrom to a desirable viewing position.
Another object of the invention is to provide novel apparatus of this character wherein a front panel of the cabinet is movable from a closed to an open position to move the picture reproducing device from a concealed position within the cabinet to a viewing position.
Other objects and features of the invention will be apparent from the following description.

Fig. 7 is a perspective view of the cabinet of Fig. 6 in open position;
Fig. 8 is a diagrammatic view of the cabinet of Figs. 6 and '7 in partially open position to illustrate the operation of the invention; and
Fig. 9 is a horizontal sectional view of the cabinet shown in Figs. 6, '7, and 8.
Referring first to Figs. 1 to 4, there is shown a cabinet for'television apparatus, having a panel I for the controls of the television receiver, a pivotally mounted panel 2 in the central portion of the cabinet, and a grille portion 3 behind which a loudspeaker may be mounted. In the cabinet of Fig. 1, these panels and grille are arranged in substantially vertical alignment.
With particular reference to Fig. 3, a television receiver chassis 4 is shown mounted on a horizontal partition 5 behind the control panel I. The chassis is preferably provided with any suitable controls 6 which may be accessible from the front of panel I. At the base of the cabinet behind the grille 3 there is provided a loudspeaker I which may be electrically connected by suitable wires (not shown) with the television chassis 4. As with all television apparatus of this type there is provided a cathode ray oscilloscope 8 positioned in the central portion of the cabinet. The oscilloscope 8 may be electrically connected to the television chassis by a suitable cable. It will be observed that the longitudinal axis of the oscilloscope 8 'is longer than the useable depth of the cabinet. In order to mount the oscilloscope 8 there is provided, in accordance with this invention, a housing 9 for the oscilloscope. The housing comprises a front panel to (see Fig. 2) having an opening ll, behind which the viewing screen of the oscilloscope is located, and suitable side walls l2. The entire housing is pivotally mount ed within the cabinet by a pin l3 which passes through the housing and suitable horizontal braces M which extend from the front to the rear of the cabinet.
The front panel 2 ofthe cabinet is pivotally mounted along its lower edge-by a hinge l5, and
a handle I6 is provided at the upper edge of the panel so that the same may be manually. moved from a closed to an open position. As is best shownin Figs. 2 and 4, the panel 2 is provided with a pair of slides I! which have a longitudinal slot running lengthwise thereof. Suitable studs I! carried by housing .0 are slidable in slides l1 within the cabinet, and when the panel 2 is open as shown in Figs. 2 and 1, the oscilloscopel and its housing are moved to an exposed position. A counterbalancing spring I! may be provided to cushion the movement of the housing 9 so that the oscilloscope is not subjected to shock at the end of either the opening or closing movement of the panel 2.
Fig. 5 shows a different type of cabinet embodying the same mechanism but with the panels and grille arranged differently. In this instance the panels Ia. and 2a and the grille 3a are arranged in staggered relation so as to properly blend into the design of the cabinet within which I the apparatus is positioned.
In Figs. 6 to 9 there is illustrated an alternative construction for television apparatus made in accordance with the present invention. In this embodiment the cabinet is provided with a generally rectangular housing 2| which supports the oscilloscope 22. Housing 2| is pivotally mounted at 23 for rotation about a vertical axis as shown in Fig. 8. Housing 2| has a front panel which is positioned centrally of the upper portion of the cabinet 20. To the left of panel 24, is a second panel 25, which is mounted for rotation about a hinge 26 as shown. An arm 21 having one end secured to housing 2| and the other end'secured to an edge of the free end of panel is adapted to cause movement of the housing 2|. This is shown in Figs. 8 and 9 where it will be seen that clockwise rotation of panel 25 will, by means of arm 21, cause rotation of the housing 2| to the open position of Fig. 7. It will be seen that arm 21 is an eccentric connection which permits the panel 25 to be closed when housing 2| is in either its closed or open position. When in open position the housing 2| projects forwardly of the front of cabinet 20 so that another panel 28 is toward the front and the viewing screen of the'oscilloscope is in proper viewing position centrally of panel 28 as shown.
From the foregoing description it will be seen that this invention provides an arrangement whereby a shallow cabinet'may be utilized to house a relatively large oscilloscope which is normally concealed within the cabinet in such a position that the longitudinal axis of the oscilloscope is parallel to the plane of the front of the cabinet, and wherein a front panel of the cabinet may be moved to an open position to cause the oscilloscope to be partially withdrawn through an opening in the front of the cabinet assaeso It will also be understood that the invention is capable of considerable modification and that the invention is limited only in accordance with the following claims. I claim:
