6 Claims. (Cl. 340-367) This invention relates to holders or supporting means for television tubes and other similar objects and particularly articles of fragile nature, and has for its primary object the provision of means by which the tube will be securely held and safely supported while in the cabinet of the set or when detached therefrom.

The present invention relates to a holder of the type shown and described in my Patent No. 2,743,435, dated April 24, 1956, and is an improvement thereover. It contemplates the provision of a tube holder so arranged that it is easily fitted on the tube and can be permitted to remain thereon at all times whether the tube is attached to the chassis or secured to the cabinet or is disconnected from the set or cabinet. It is one of the objects of the invention to provide a tube holder which can be largely constructed of metallic rod; which will possess sufiicient strength :to protect the tube and yet shall be sufiiciently resilient or springy to enable it to be readily conformed in shape to the peripheral edge of the tube and engage or grip the same sufliciently to avoid shifting movement of the tube, but without the application of excessive gripping force likely to damage or fracture the glass envelope of the tube.

More particularly, the invention contemplates the provision of a single-rod split ring encircling the periphery of the tube and clamped about thesame, and a plurality of spaced brackets welded to either the inside or outside of the ring at the four corners (quarters) of the tube, which brackets are shaped to restrain forward and backward movement of the tube relatively to the ring and are provided with means by which they may be attached to the interior of the cabinet and to the set chassis and are also provided with means by which a wire-rod harness extending around the rear of the tube may be engaged and adjustably fitted in position and maintained on the tube. v i 1 With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawings, wherein an ilustrative embodiment of the invention is disclosed, v

Fig. 1 is a front elevational view of a holder for television tubes and other objects, constructed according to the present invention;

Fig. 2 is a top plan view of one of the brackets;

Fig. 3 is a side elevational view of .the bracket shown in Fig. 2, with parts in section;

Fig. 4 is a top plan view, on a reduced scale, of a second form of bracket;

Fig. 8 is a top plan view of the adjusting means shown in Fig. 7; and

Fig. 9 is a side elevational view of a slightly modified form of bracket, with a portion thereof shown in section.

Referringto the drawing, 1 indicates the tube-encircling and holding ring. The same is preferably composed of a single length of springy metallic rod and is of a shape to enable it to encircle the television tube 2 and closely fit about its periphery 3 adjacent to the forward or larger end of the tube as shown in Fig. 6. The ring is split or divided as indicated at 4 in Figs. 1 and 7. Secured to the ends of the split ring as by welding are angle-

pieces

5 and 6 which are transversely ribbed as shown at 7 and each of the angle-pieces is provided with an off-set end 8 through which an adjusting bolt 9 extends. The bolt is provided with a nut 10 and by suitable positioning of the nut along the length of the bolt 9 the angle-pieces are drawn toward one another or separated to an extent to draw the ring 1 closely around the periphery 3 of the tube 2 and clam'pingly grip the same. If desired, pads or otherpressure-absorbing elements might be interposed between the encircling ring and tube or between the brackets thereon and the tube.

Secured to the encircling ring by welding at positions locating them at the four corners of the tube, are brackets indicated at 11 and 12 which may be welded to either the inside or outside of the ring 1. All of these brackets are substantially similar, but have slight differences as will be apparent from a comparison of Figs. 2 and 4. Each bracket is formed with a forward, out-turned lug 13, having an aperture 14, through which bolts, screws or other fastening members may be extended to fasten the ring and hence the tube supported by it to the chassis and to the inside surfaces of the television set cabinet. Each bracket is suitably ribbed as shown at 14a and 15 thus facilitating the spot welding of the wire rod ring 1 to the brackets as well as fastening rods shown at 17. The rods shown at 17 are welded to the two brackets shown at 11, and each of these rods is provided with screw threads indicated at 16 to receive adjustment nuts 18a.

Each of the two brackets shown at 12 is formed adjacent to its rear end, with a stamped-out hook member 18. Extending rearwardly from the retaining ring 1 is a harness composed of metallic wire rod, which harness includes a pair of

rods

20 and 21 connected in spaced relation by the cross rods 22, thus providing a central frame through which the stem 23 of the television tube is extended substantially as shown in Fig. 6. Each of the

rods

20 and 21 has two legs indicated respectively at 24 and 25. As shown in full lines in Fig. 1, each of the legs 24 extends to a bracket 12 and is formed with a looped end 26 engaged with the hook 18 on each of these brackets. Each of the legs extends to a bracket 11, and each of these legs is formed at its end with a loop 27 which encircles the threaded rod 17. It will be apparent that by this arrangement, the adjustment of the nuts 18a on the two threaded rods 16 will result in the harness being snugly drawn around the rear portion of the tube substantially as shown in Fig. 6, so that the tube is thus embraced between the ring and brackets at the forward end of the tube, and the rear frame of the harness at the back end of the tube.

It is to be noted that the shape of the

brackets

11 and 12 is such that the forward portion 30 of each bracket is inclined inwardly toward the center of the tube, which arrangement tends to prevent forward shifting movement of the tube relatively to the ring 1. At its rear end, each bracket is again bent inwardly, as indicated at 31, which conforms it to the conical shape of the tube and tends to prevent backward movement of the tube relatively to the ring 1.

A modification of the manner of applying the harness to the rear of the tube is suggested in dotted lines in Fig. 1, wherein the legs 24 of the

rods

20 and 21 are disposed in crossed relationship, so that the leg 24 on rod 20 engages the bracket shown at 12a, while the leg 24 of the rod 21 is engaged with the bracket shown at 1212. This crossed relation of the legs 24 may be also employed with the legs 25 if it is found desirable or necessary.

From the foregoing, the construction and use of the improved television tube holder will be readily apparent. The device is constructed of few parts, most of which are of springy or resilient metal rod. The brackets employed in the device are shaped to not only resist shifting movement of the tube within the holder but to provide fastening lugs by which the holder and the tube held by it can be secured to the chassis or cabinet. The holder may be readily mounted on the television set chassis and can also remain on the tube when the tube is demounted from the chassis or cabinet and will then serve as a protective holder or carrier for the tube.

While I have herein suggested that the rear harness be employed in conjunction with the front encircling ring and the brackets attached thereto, it is possible to employ the ring alone and detached from the harness, particularly should relatively flat or shallow tubes come into general use. The rear harness is a safety factor in the event of a back or rear drop accident. As will be noted in Fig. 6, the members 22 of the harness are each provided with an indentation 22a which can be employed to receive the end of a coil spring 37 having its other end attached to a focussing coil 38, or rear yoke or other electrical or mechanical elements which might be needed at this location. Two springs 37 are employed at opposite sides of the tube.

In Fig. 9 is shown a slightly modified form of bracket, wherein the hook 18 is shown as being located forwardly of the angular portion 31. This hook can be employed for the reception of a grounding wire. The angular part 31 can also be provided with a rubber grommet 31a forming a cushion for contact with the tube. With this arrangement the rear harness might be dispensed with.

Having described an embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.
