DISPLAY TUBE MOUNTING ARRANGEMENT Filed July 2, 1968 F 4 230 INVENTDR.
\5 x30 WILL/AM M. HENA/ESSEY ATTORNEY United States Patent 3,522,483 DISPLAY TUBE MOUNTING ARRANGEMENT William M. Hennessey, Somerville, NJ., assignor to Burroughs Corporation, Detroit, Mich., a corporation of Michigan Filed July 2, 1968, Ser. No. 742,031 Int. Cl. H02b 1/04 US. Cl. 317-99 6 Claims ABSTRACT OF THE DISCLOSURE The disclosure is of apparatus for mounting a series of indicator tubes comprising a bracket including openings for receiving the tubes and having a keyway adapted to mate with a key on a mounting member coupled to the tube. The mounting member includes a relatively large slot for receiving a group of tube pins or leads, and a plurality of holes for receiving separate ones of the leads to provide coupling and alignment of the mounting member with the tube.
BACKGROUND OF THE INVENTION There are many types of instruments on the market, for example calculators, meters, counters and the like which utilize a plurality of character display tubes mounted sideby-side in a row. It has been found that it is relatively difiicult to mount a large member of tubes, particularly tubes with flexible leads, so that they are all oriented identically without one being twisted slightly with respect to another.
SUMMARY OF THE INVENTION Briefly, the invention comprises the provision of a mounting member adapted to be coupled to each tube and held by the tube leads and including a key adapted to orient the mounting member and its tube in a mounting bracket.
DESCRIPTION OF THE DRAWING In the drawings:
FIG. 1 is a perspective view of a bracket used in practicing the invention;
FIG. 2 is a perspective view of an indicator tube and a mounting disk used in conjunction with the bracket of FIG. 1;
FIG. 3 is a bottom view of the tube of FIG. 2 showing a typical lead arrangement; and
FIG. 4 is a front elevational view of a portion of the apparatus of FIG. 1 with the apparatus of FIG. 2 secured thereto.
DESCRIPTION OF THE PREFERRED EMBODIMENT The apparatus of the invention is adapted to support a plurality of display tubes in instruments such as calculators, meters, or the like. One tube of this type is the B5750 made by Burroughs Corporation. This tube is known as a side-view tube and includes an enevelope 30 having a base or stem 40 and a dome 50 which carries tubulation 60. The tube 20 contains an electrode assembly (not shown) which includes a plurality of cathode char acter electrodes arranged in a stack, an anode electrode which surrounds the stack of cathodes, and at least two auxiliary character electrodes, usually decimal points. The stem 40 carries two parallel rows of pins or flexible tube leads 100 are connected to the cathode electrodes, two other pins 110 which are spaced apart near the rear of the tube and are secured to the anode electrode inside the envelope, and two other pins 120 near the front of the 3,522,483 Patented Aug. 4, 1970 tube which are spaced apart and are connected to the auxiliary character electrodes.
The apparatus of the invention includes an insulating mounting member or disk adapted to be coupled to each tube 20 and to be used in mounting the tube in a bracket which itself is mounted in the instrument and supports the indicator tubes in viewing position. The disk 130 has a generally fiat base from which a generally circular pedestal portion rises. The circular portion 150 includes a central slot 160, two closely spaced aper tures near one end of the slot and two relatively widely spaced apertures near the front of the slot. The disk 130 also includes a keying post which rises above portion 150 near one corner of the base.
In use, the disk 130 is coupled to a tube 20 by inserting the two anode pins 110 in the two closely spaced holes 170 and the two pins 120 to the auxiliary electrodes in the widely spaced holes 180, and the cathode pins or leads 100 are inserted in the slot. The disk 130 is pushed up against the stern of the tube and held in place by mechanical engagement of the pins or leads with it. One or more pins may be bent over to securely engage the disk 130.
The apparatus 10 also includes, according to the invention, a generally U-shaped bracket 200 which is intended to carry the display tubes 20 and includes a top wall 210, a back wall 220, and a bottom wall 230. The bottom wall 230 includes a plurality of generally circular openings 240, each of which has a keying notch 250 at the same location on the periphery of the circle. The top wall 210 carries a rubber or other resilient strip 260' cushioning the domes of the tubes and a plurality of apertures 270 which are adapted to receive the tubulations of the display tubes, if such are present.
With a disk 130 coupled to each tube 20, the tube is inserted through the large circular opening 240 in the bottom wall 230, and it is set in place with its tubulation 60 in an aperture 240 in the top wall 210, with the key post 190 forming a tight fit in the keying notch 250 in the bottom wall, and with the circular pedestal 150 inserted in and forming a tight fit in opening 240. The dimensions are sufiiciently close in tolerance so that the disk 130 carrying its tube 20 is held tightly in the bottom wall.
With this arrangement, it can be seen that all of the tubes mounted in the bracket 200 are oriented identically on their spacers 130, and all of the spacers 130 are oriented identically on the bracket, due to the keying post 190, so that all of the tubes are oriented and positioned correctly and as desired.
What is claimed is:
1. A mounting arrangement for tubes of the type which includes an envelope having a tubulation at its upper end and a stem in which a plurality of flexible tube leads are sealed, said arrangement including an insulating disk having apertures for receiving tube pins and for supporting a tube, said disk having a key post, and a generally U-shaped bracket having a bottom wall,
a side wall, and a top wall, said bottom wall having a plurality of apertures, each being identical in size, shape, location and orientation, and each including a keyway and each adapted to receive said disk, with said key post oriented in said keyway, said top wall having a relatively small opening aligned with each of said apertures in said bottom wall for receiving the tubulation of each tube mounted on a disk seated in one of said apertures in said bottom wall.
2. The apparatus defined in claim 1 wherein each disk provides a tight fit with its aperture.
3. The apparatus defined in claim 1" wherein each di'sk includes an elevated portion which is seated in frictional engagement in its said aperture.
4. The apparatus defined in claim 1 wherein each disk includes a central slot for receiving selected ones of said tube leads, and other apertures positioned near the periphery of the disk for receiving others of said tube leads.
5. The apparatus defined in claim 1 and including cushioning means positioned between each tube and the top wall of said bracket.
6. The apparatus defined in claim 1 wherein each disk includes a central slot for receiving selected ones of said tube leads, and other apertures positioned remote from said central slot for receiving others of said tube leads. 15
