PROTECTIVE COVER FOR- TELEVISION TUBES Filed Aug. 19, 1949 IN VEN TOR. EDWARD A. RIE BY W 0R mm Patented Feb. 19, 1952 OFFICE PROTECTIVE COVER FOR TELEVISION TUBES Edward A. Ried, Jr., Camden, N. J.
Application August 19, 1949, Serial'No. 111,117
This invention relates to a shield or cover for protecting high voltage radio tubes, such as cathode tubes, used in television receivers.
Such tubes are fragile and expensive and are easily broken and such breakage is not only expensive because of loss of the tube but may injure the worker.
This invention has for its object to provide a simple, practical and inexpensive protective cover for tubes of the character described, and a cover so constructed that the tube can be used without removing it from the cover, as, for instance, on the bench.
Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application, and in which Fig. 1 is a perspective elevational view of a protective cover constructed in accordance with the invention;
Fig. 2 is a longitudinal sectional elevation taken substantially on line 22 of Fig. 1, looking in the direction of the arrows;
Fig. 3 is an end elevation of the structure shown in Fig. 2 taken substantially on line 3-3 of Fig. 2, looking in the direction of the arrows;
6, Claims. (Cl. 17 7*316) dowel pins 2| extending downwardly therefrom and adapted to be received in recesses or sockets 22 formed in the base. Three sets of these sockets are shown and the upright or bracket 20 can be adjusted or moved to a position over any one of the three sets. The upright 20 also has a saddle 26 at the upper end thereof for receiving the cylindrical portion l2 of the tube. The tube is held in the saddle 26 by a strap 21, similar to nected by a conduit 36 to the contact 14 on the' Fig. 4 is a vertical sectional elevation taken substantially on line 44 of Fig. 2, looking inthe direction of the arrows; and
Fig. 5 is a horizontal sectional elevation taken substantially on line 5-5 of Fig. 2, looking in the direction of the arrows.
In the particular embodiment of the invention illustrated in the drawings, the protective cover comprises a base I0 which may be of any suitable material, such as wood, and a cover I I, preferably formed of transparent plastic material, such as that known under the trade-mark Plexiglas.
In Fig. 2 there is shown a cathode tube of the type used as a receiver in television sets, this tube comprising a cylindrical portion [2 and a flared end portion l3 of the usual construction. The end portion 13 has a conductive coating on the inner surface thereof (not shown) and a terminal M- leading to the conductive coating and adapted to be connected at a high potential source.
The base It) has secured thereto intermediate it ends, an upright 0r bracket l5 having a saddle 1B for receiving the cylindrical portion I2 of the tube. The tube is preferably clamped therein by means of a strap i! which may be buckled in any 'desired manner at la. The base has also supported thereon. an upright or bracket 20 having the strap 11, and is buckled in position in a like manner.
The rear end of the protective cover H has an opening 28 through which may be inserted a socket 29 which leads to the television set or other set in connection with which the tube is to be used or tested. The socket 29 is connected to the terminal 30 on the rear end of the tube.
The outer surface of the cover has thereon a contact 35, which is adapted to be connected to a high voltage source, and this contact is conportion l3 of the tube.
From the foregoing description it will be seen that the tube will be securely mounted on the base I0 and protected from outside breakage by the cover II and can be used for testing purposes on the bench when it is mounted in the cover ll. Furthermore, the protective cover is so light in construction that it can be readily transported when desired.
Although one specific embodiment of the invention has been particularly shown and described it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the variou cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
What I claim is:
1. A protective casing for television tubes comprising a base, brackets on the base for support ing the tube from below, means for holding the tube on the brackets, and a cover of transparent material dimensioned to fit over the base and receive the tube.
2. A protective casing for television tubes comprising a base, brackets on the base for supporting the tube from below, means for holding the tube on the brackets and a cover of transparent plastic material dimensioned to fit over the base and receive the tube.
3. A protective casing for television tubes comprising a base, brackets on the base for support ing the tube from below, means for holding the tube on the brackets, and a cover of transparent material dimensioned to fit over the base and receive the tube, said cover having a contact on the outer surface thereof and a conduit inside the cover connected to said contact and adapted to engage a contact on the outer surface of the tube.
4. A protective casing for television tubes comprising a base, brackets on the base for supporting the tube from below, means for holding the tube on the brackets, and a cover of transparent material dimensioned to fit over the base and receive the tube, said cover having an openingin the rear end thereof adapted to receive a socket and leads connected to thesocket.
5. A protective casing for television tubes comprising a base, brackets on the basefor supporting,
the tube from below, means for holding the tube ceive the tube, certain of said brackets being adjustably. mounted on the base;
6. A protective casing for television tubes comprising a base, brackets on the base having saddles for supporting the tube from below, means for holding the tube on the saddles of the brackets, and a cover of transparent material dimensioned to fit over the base and receive the tube.
