Application August 3, 1953, Serial No. 371,952
7 Claims. (Cl. 81-3) This invention relates to an electronic tube puller and replacer whereby a repair man can easily remove an electronic tube from a radio or television set, and in removing this tube it is so indexed that it can easily be replaced by the repair man without devoting a great deal of time to hunt the required position of the contact pins or prongs of the tube in its socket.
An object of my invention is to provide a novel electronic tube puller and replacer in which a ring is mounted on the chassis or socket in such a way that it cannot be easily disturbed, that is, it cannot be easily rotated out of its initial position on the chassis or socket. The tube engaging remover is indexed relative to the ring so that this remover can be readily returned to the position in which it originally removed the electronic tube from the set.
Another object of my invention is to provide a device of the character stated in which the ring is mounted on the chassis or the socket by means of magnets, and the tube puller is provided with a pair of arms, these arms in turn being indexed relative to the ring so that the arms will enter the ring in only one position.
A feature of my invention resides in the novel means whereby the ring can be removed by the tube puller after the electronic tube has been replaced in the set.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.
In the drawing:
Figure 1 is a perspective view of the electronic tube puller.
Figure 2 is a transverse sectional view of the ring and showing the tube puller in position to remove an electronic tube.
Figure 3 is a perspective view of the ring.
Figure 4 is a perspective view of a modified form of r the ring.
' Figure 5 is a perspective view of a tube indexing device.
Figure 6 is a transverse sectional view of the tube indexing device and showing the tube puller positioned therein.
Figure 7 is a perspective view of the socket portion of the tube indexing device.
Referring more particularly to the drawing, television and radio sets are provided with either a metallic chassis in which the various tube sockets are mounted or the upper surface of the socket itself is metallic. My electronic tube puller and replacer consists of a ring 1 which is mounted on the chassis or on the socket in a relatively fixed position by means of the magnets 2 and 3. The magnets 2-3 engage either the chassis or the socket in the chassis and, consequently, hold the ring 1 so that it cannot be readily disturbed from the position in which it is initially placed. As an alternative, a ring 4, similar to the ring 3, can be mounted in the chassis by means of downwardly projecting prongs 5-6 which enter appropriate holes in the chassis or socket, thus non-rotatably 2,783,667 Patented Mar. 5, 1957 holding the ring 4 in position and again permitting the electronic tube to be properly replaced, as will be subsequently described. The ring 1 is provided with two vertical grooves 6 and 7 which are diametrically opposed, the one groove 6 being materially wider than the groove 7 so that the tube puller and replacer, to be subsequently described, will fit into the ring 1 in only one position.
The tube puller and replacer 8 consists of a pair of prongs or arms 9 and 10, the arm 9 is wider than the arm 10 and the arm 9 fits into the groove 6, while the arm 10 fits into the groove 7 of the ring 1. The arms 9 and 10 are pivotally mounted in a head 11, which consists of two side plates 12-12. The head 11 also includes a base 13 which extends horizontally between the plates 12-12. A threaded pin 14 rises from the base 13 and a cone 15 screws onto this pin. The cone 15 engages the upper ends 16-17 of the arms 9-10, respectively, for the purpose of pressing the arms 9 and 10 inwardly against the electronic tube 18, for the purpose of removing and replacing this electronic tube from the radio or television set. A spring 19 engages the arms 9-10 for the purpose of pressing these arms outwardly when the cone 15 is threaded upwardly on the pin 14. The purpose of this spreading action being to engage outwardly projecting ribs 20-21 on the arms 9-10, respectively, these projections or ribs engaging the bottom of the ring 1 so that this ring can be readily retrieved after the electronic tube has been replaced in the set.
As thus far described, it is assumed that the same tube is replaced in the set as was removed therefrom. However, if it is found that the tube is defective and a new tube must be inserted in the set, I then provide an orienting or indexing device as follows: A ring 22 similar in arrangement and construction to thering 1, except that no magnets or pins are mounted thereon. A simulated tube socket 23 which has the same holes 24 therein to receive the prongs of the electronic tube as the real socket.
in the set, the socket 23 is provided with arms 25-26, the upper ends of which fit into the annular groove 27 in the ring 22. A set screw 28 in one of the arms 25 or 26 engages the ring 22 for the purpose of holding the socket 23 against rotation.
In operation the ring 1 or 4 is first mounted on the chassis or tube socket and is held in fixed position by means of the magnets 2-3, or by means of the pins 5-6. The puller 8 is now placed over the tube 18 and is oriented relative to the ring 1 because the arm 9 can only fit into the slot 6 of the ring 1. The arms 9 and 10 are now pressed inwardly against the tube 18 by screwing the cone 15 downwardly. Once the tube 18 has been" gripped it can be pulled upwardly by the puller 8 and removed from the set without disturbing the ring 1. The tube 18 is now checked in the usual repair mans checker. If the tube is found to be in proper working order, it is returned to the set and can be easily replaced in its socket, since the puller 8 is indexed relative to the ring 1 and the ring 1 has thus far not been disturbed. After the tube 18 is replaced, the ring 1 is removed from the set by spreading the arms 9-10 outwardly so that the ribs 20-21 engage the bottom of the ring and permit it to be pulled upwardly.
It is understood that the tubes 18 are the very small electronic tubes in common use, and in large sets these tubes are placed very close together and also in very inaccessible places so that the repairman can frequently not see the socket in which the tube is to be placed. If the tube 18 is found to be defective, it is still held in the remover 8 and this remover is then placed in the ring 22. The simulated socket 23 is now rotated until the prongs of the tube will fit into the holes 24. The set screw 28 is now screwed against the ring 22, thus fixing the socket 23 with relation to the ring 22. The defective tube is now removed and anew tube is inserted into thesocket 23. Thereafter the remover 8 is again caused to grip the new tube in the same manner previously described, and
the new'tube is thus exactly indexed-With the position of the defective tube as it was removed from the set; The new tube can now'be replaced in the set in thesame man-v ner described above.
