Patented Dec. 8, 1942 UNITED STATES PATENT OFFICE TELEVISION APPARATUS Raymond S. Yoder, Chicago, Ill., assignor to Galvin Manufacturing Corporation, Chicago, Ill., a corporation of Illinois Application June 26, 1941, Serial No. 399,763
(ci. 17a- 7.5)
This invention relates generally to television apparatus and in particular to a housing and supporting means for the picture means of television receiving apparatus.
In .television receiving apparatus of the prior art it is usual to employ picture or scanning tubes in providing for a visual display of the televised material. These tubes are usually about sixteen to twenty-four incheslong,` with the picture face or screen being arranged at one end thereof. It is evident, therefore, that the picture face is most conveniently viewed when the tube is in a substantially longitudinal position in its associated cabinet or supporting structure, with the picture face arranged at the cabinet front. However, the relatively long length of the tube-requires a cabinet of considerable depth to completely enclose the tube in this position whereby `to appreciably increase its size and bulk, as compared to the usual console radio cabinet, and hence its cost. In attempts to overcome this increase in cabinet size, the picture tubes have been arranged in a substantially vertical position within the cabinetswith the picture face arranged in a top wall or panel of the cabinet. In order to have the representations on the picture screen visible from a position in front of the cabinet, a top lidv or cover for the cabinet is provided having a mirror or like reflecting surface on the 'underside thereof in operative association with the picture face. Although this 'arrangement oi the picture tube in the cabinet appreciably reduced the size of the cabinet, particularly as to depth, it was not entirely satisfactory because of the indirect viewing of the representations on the picture screen, and the limited view of the reiiecting'mirror .over a rather restricted radius, as well as longitudinal level, from a position before the cabinet. Also amirror utilized in this manner reduces the illuminating elect of. the picture screen, and further increases the cost of the television apparatus.
It is an object of this invention, therefore, to l television apparatus including a shallow cabinet for a scanning tube in which the tube is sup-r Cil ported to 'provide for the ,projection of the picture screen during operation of the apparatus from the front of the cabinet and for the moving of the entire tube within the connes of the cabinet when the apparatus is not in use.
A still further object of this invention is to "provide television apparatus including a shallow 'cabinet and a scanning tube which is pivotally supported in the cabinet to provide for an angular swinging of its picture screenvduring operation in an arc outwardly f rom the `front of the cabinet, and for a positioning of the tube entirely within the cabinet when the television apparatus is not in use.
A feature of this invention is to provide a cabinet for television apparatus including a scanning tube of elongated type, which is shallow, has substantially integrally assembled top and side portions to provide for an overall rigid construction, is relatively inexpensive in cost, and is cooperatively assembled with means for supporting the scanning tube to provide for a substantially longitudinal operating position of the tube 'with its picture face at the front of the cabinet and for a substantially vertical rest position thereof entirely within the confines of the cabinet.
A further feature of this invention is found in the provision of a shallow cabinet for television apparatus including an elongated type picture unit, which has a compartment for the unit provided with an open side at the front of the cabinet and means in the compartment for pivotally supporting the picture unit so that'the picture screen thereof is pivotally movable across v such open side in an arc projected outwardly from the frontof the cabinet. A cover for ,the open compartment side is carried by the picture unit meanstherein to provide `for the assembly and removal of the same from the cabinet as a complete unit. Y
' Further objects,.features and advantages Vof this invention will become apparent from the iolf lowing description when taken in connection with the accompanying drawings in which:
Fig. 1 is a front view of a cabinet for television and radio receiving apparatus showing the picture means in an operating position;
Fig. 2 is a side view of the cabinet in Figi 1 showing the picture means in an operating position corresponding to that in Fig. l, with parts of the cabinet being removed for the purpose of clarity; I
Fig. 3 is illustrated similarly to Fig. 2 and shows the picture means with a cooperating lens for the picture screen; v
Fig. 4 is a front view of the cabinet showing the idle or rest position for the picture means;
Fig. 5 is a fragmentary detail view looking at the picture means from the rear as viewed in Fig. 4; A
Fig. 6 is a' fragmentary view of the means for supporting the picture means in the cabinet; and
Fig. 'I is a view looking toward the left as e seen in Fig. 6.
otally supported at one end on the mounting plate -38 by axis means 38 and having an enlarged bearing portion 34 to releasably lock ,the axis member 32 in such bearing. vThe latch member I3 and I4, respectively. Intermediate the abovef mentioned two compartments is a compartment I8 for receiving a scanning or picture unit I1 for the television apparatus. 'I'he intermediate compartment I8 isseparated from the two end compartments by abbreviated side wall members evident, therefore, that the top 2i of the .cabinet 38 is yieldably maintained in a latching position by a tension'spring 43 connected at one end to a lug 44 onthe'mounting plate 38, and at its other end to a lug 48 on the latch member 38.
The pivotal movement of the latching member 38 to a latching and releasing position relative to the pivot member 32 is defined by the sliding engagement of a pin element 48 carried by the latch in an arcuate slot 41 formed in the mounting platev 38. It is evident, therefore, that the extent of pivotal movement 'of the latch 38 is limited by the length of the arcuate slot 41.
In the assembly of the picture unit I1 in the cabinet I0 the unit is inserted in the compartment I8 through the open side I8 thereof with the screen 28 toward the front of the cabinet and with each axis member 32 positioned on a corresponding one of the side members I8 of the compartment I8. The entire unit is then slidably moved toward the rear of the cabinet until lthe axes 32 drop into their corresponding bearing portions 34. As the axes or pins 32 approach the bearing portions 34 they engage and move the latch members 38 away from a closing posi- I tion relative to the bearing portions 34, against the tension of the springs 43. Thus on -dropping vof-the pins 32 into the bearing portions 34,- the does'not function .as an ordinary lid or cover.
ybut cooperates with the other-fixed fralnefvporl-l tions of the cabinet to'provide in alla cabinet structure which is rigid and ruggedandjoapable of easily and solidly supportingtliereintheicoxnbined weight of the television and radio receiving apparatus. e
The picture unit I1- in comprises a picture tube 24 (Fig. 2)l having a length greater than the depth of the cabinet III.
the compartment le The tube 24 includes a picture face'or screen 28 at one end thereof, and a base or electrical connecting portion 21 at theI other end adapted for mating electrical engagement with a socket or lthe like (not shown) provided at one end of a supported ina mounting structure including side members 28 (Flgs. 5, 6 and 1) and a base portion 3|. Each side member 28 is provided with an axisv member 32 which is flxed thereon in ausual manner by means of cooperating cup members 33. i
The axes members 32 are rotatably supported,
in combination bearing and latching 38 including an open bearing portion 34 which is mounted on the top of a corresponding one of ,the wall members I3 for the compartment I8.
Each unit n is integrally formed with a mounting plate 38 positioned against a sideA of a wall member I8 and secured thereto as by screws 311.
ing portion 34 is bent substantially normal to the mounting plate 38. Each axis orv pivot 32 is releasably retained in a corresponding bearing latching members 38 are immediately returned to a latching or bearing closing position by the` springs 43. When the unit I1 is removed from the cabinet, the latching members 38 are first' moved away from a bearing closing position and the unit I1 then lifted from the bearings 34 and slidably moved forwardly of the cabinet on the side walls I8. Itis seen, therefore, that the unit I1 is inserted into the cabinet I8 as a unit through the open side I8 of the compartment I8 and is releasably supportedftherein to facilitate its removal and assembly for service and manu- .70 As is clearly evident, from Figs. 6 and 7, the bearas previously mentlned, the cablnetln is of.
a relatively shallow construction, and the tube 24 may be about two feet long, which length is Vappreciably longer than the depth of the usual cabinet now usedV for console radios and contemplated for use with television apparatus. Thus when the picture tube is in a longitudinal position, as when the television apparatus is in operation, the picture screen is projectedforwardly from the cabinet (Fig. 2) for direct viewing. With the picture screen 28 at the front of the cabinet and also projecting outwardly fro'm the cabinet, the area before the cabinet within which the. screen can be easily and comfortably portion 34 by means of a latch member 33 piv- 75 viewed is appreciably increased. Also brvirtue of the angular swinging of the picture screen vertically across the open side I9 of the compartment, adjustment of the screen isl accomplished to provide for a positioning thereof at a desired height for viewing by persons seated before the cabinet. The retention of the screen 26 in a desired adjustedposition is obtained by means including counterweights 41' carried on the mounting structure for the picture unit at the end thereof opposite the picture screen 26. The weights are of a predetermined size and adapted to cooperate with the frictional resistance at the bearings 34 to maintain the picture unit I1 stationary at any set position. It is evident of course that when thefpicture unit is not adjustable, the weights 41 can be eliminated and suitable means provided to lock the unit-. in its rest and operating positions.
When the television apparatus is not in operation the unit l1 is` swingable downwardly from its substantially longitudinal position shown in Fig. 2 with a'portion projecting from the cabinet I to a substantially vertical position shown in Figs. 4.and 5 completely within the compartment I6 and entirely within the connes of thecabinet l0. 'I'he wall portion 4 8 of the mounting structure for the picture unit l1, which is arranged opposite the base portion 3l and is substantially coextensive in length withv the tube 24,h constitutes a cover or lid for the open side I9 of the compartmenty I6` Thus as the unit Il is pivotally moved to a substantially vertical position, the cover `48 is moved into a position for closing the side i9' and hence the compartment I6. As is clearly shown in Fig. 4, the cover 48 in its closing position forms apart of the front of the cabinet I0. Thus when the 'television apparatus is not in operation, the entire picture unit Il is completely enclosed within the cabinet so as to entirely hide from view the unsightly picture screen 26 without in any way providing for an increase in the depth of the cabinet I0. A large and bulky cabinet is thus entirely eliminated, while permitting the picture tube to operate in a longitudinal position with the picture screen 26 easily andcomfortably visible at the front of the cabinet.
In some instances of installation, it is desirable that the picture or representations on the picture screen 26 be enlarged by a cooperating lens or the like. An assembly of the picture unit Il including a. lens 49 arranged in a cooperating relation with a picture tube 24' is illustrated in Fig. 3.` As shown the overall length of the unit I1' is substantially the same as the overall length of theunit I1 because of the tube 24' being somewhat shorter than the tube 24 but having a somewhat wider scanning angle. However, it is ob vious that thetubes 24 and 24 may be of the same length andv the unit il' increased to a length greater than theunit Il. 'I'his .increase in the length of the unit l1' is readily accom- .imodated by the compartment I6 by increasing the length thereof in Aa direction downwardly of the cabinet I0 an amount corresponding to the increase in the length of the unit I1'. It is seen, therefore, that the housing' and supporting of the picture unit for direct viewing thereof from the front of the cabinet, and the complete confinement thereof within the cabinet when it is not in operation, ,is accomplished equally well with a picture tube alone or with a picture tube in combination witha cooperating lens.
From a consideration of the above description and drawings it is seen, that the inventionproto a plurality o'f operating positions. The projecting of the picture screen from the front of the cabinet, when the television apparatus is being operated, improves the visibility of the plcture screen over an increased radius in front of the cabinet while its complete retraction within the cabinet when it is not being used and the covering thereof by-a front portion of the cabinet materially improves the overall appearance ofthe cabinet.
