SIZE COMPENSATING ELEVATION POST Filed Oct. 17, 1941 INVENTOR ,5 /)M(/'L Ci/W/uma ATTORNEY Patented Mar. 7, 1944 SIZE COMPENSATING ELEVATION ros'r Samuel 0. Miller, New York, N. Y. 7 Application October 17, 1941, Serial No. 415,350

7 Claims.

This invention relates to elevation posts, more particularly to elevation'posts for use in connection with supporting tubular gaseous tubes or illuminants in position and still more particularly to insulator elevation posts.

My invention has for its object the provision of insulator elevation posts for holding tubular gaseous discharge tubes, or so-called neon sign tubing in position without the necessity of resorting to twisted wire ties heretofore known to me to have been employed with glass elevation posts.

Still more particularly, my invention resides in the provision of an insulator elevation post which may be made of molded insulating material such as glass and synthetic plastics which will minimize the labor in affixing insulators of this character in position, as well as to present an attractive appearance whil permitting wide tolerance in size to compensate for diilerent sizes of tubings employed.

Reference will be made to the accompanying drawing for exemplification of the objects heretofore mentioned. Other objects will become more apparent as this description proceeds. For this purpose I make reference to the accompanying drawing forming a part hereof in which:

Figure 1 is a front elevational view of my device, a portion of which is shown in section to illustrate the internal construction;

Figure 2 is a side elevation thereof Figure 3 is an exploded perspective view of the sections of my device;

Figure 4 is a View similar to Figure 1 with a larger tube in position showing a sectional view of the post clip in position;

Figure 5 is a side view thereof; I

Figure .6 is a section taken on the line 6-6 of Figure 4.

Making reference to the drawing, my invention contemplates the provision of an elevation post If) shown in Figure 1 which is made of insulator materials such as glass, porcelain or synthetic thermoplastic resinous materials which may be molded, cast or otherwise shaped.

My device constitutes sections II and I2, the two forming complementary shanks of general semi-circular cross section adjacent the upper end. Each shank extends into fingers I3 and I4' angularly outwardly directed and terminate in inwardly directed sections I5 and I6, defining bearing portions I'I, I8, I9 and 20 arranged to form a seat for a tube T.

The sections II and I2, when in contact with each other, along the surfaces 2| and 22 with their bottom ends coterminus, will serve to embrace within the fingers I3 and I 4 a predetermined size of glass tubing cooperating with well known elevation post clips to thereby serve to hold the sections II and I2 together in tube embracing position without further manipulation.

Thus, it will be readily-understood that in order 'to aflix the elevation post into tube holding position the worker need merely position the sections II and I2 to opposite sides of the tube T and thereafter slip a clip (not shown) into position. This operation thereby eliminates the labor involved in twisting wires'heretofore employed to bind the tube to the elevation post.

Since it is found that the tubes vary in size, I have devised elevation post clips which cooperate with the elevation post sections heretofore described to provide a wide tolerance in adjustment compensating for various sizes of tubing which may be encountered in practice.

, For this purpose, reference is made to Figure 4 where I have illustrated a sleeve 28 generally cylindrical in cross section, which has extension cars 29 and 3!] on the respective branches of the clip through which the standard 3! passes to bind the sections II and I2 to each other, and thereby hold the fingers I3 and I4 in position embracing the tube 21.

I secure a resilient action urging the sections I I and I2 into position by the provision of resilient fingers 32--32 which engage the

grooves

25 and 26 to hold the clips in adjustable positions along the length of the sections I I and I2.

To further compensate for the difference in sizes, of tubings 21 which may be encountered, I find it desirable to bevel the faces 2I and 22 adjacent the

edges

23 and 24 thereby to secure the proper spread of the sections I I and I2 from each other while retaining as much surface contact as possible and the maximum circular character of the sections as will be readily understood. To assure longitudinal alignment of the

grooves

25 and 26 where these are used, or where screw threading is used to secure longitudinal adjustment of the elevation post Iv may also key sections II and I2 to each other and for this purpose, I thereby. provide the section. II with a depressed section 45 into which the extruded lug 46 may extend into keying engagement holding the sections II and I2 diametrically aligned and longitudinally aligned.

It will be understood that the extensiveness of the spring fingers 3232 in the clips 28 may be Varied to take care of the divergence in spring of the sections H and H. as difierent sizes of tubing 21 is encountered.

It will be observed that I have thus provided an elevation post for holding neon sign tubings or the like gaseous tubular illuminants in position, employing a preformed tube engaging elevation post eliminating thereby heretofore employed wire ties, as well as the labor incident to effecting the tie by the cumbersome twisting action to which these ties are subjected in order to effect the binding action. I

It will be observed, also, that I have provided a novel combination elevation post and adjustable mounting means therefor in connection with which the adjustable means of my application Serial No. 337,193, filed May 25, 1940, and Serial No. 369,798, filed December 12, 1940, are particularly found desirable.

It will be understood that while the most preferred results are secured by the employment of all of the features as shown in the exemplified construction, that I am not to be limited thereby and that novelty is attributed to segregated portions thereof as set forth within the scope of the appended claims.

Having thus described my invention and illustrated its use, what I claim is new and desire to secure by Letters Patent is:

In an insulator elevation post for luminous tubes, a sectionalized segment comprising shank forming portion, having at one end thereof a seat or saddle forming portion and a shaped tube engaging finger to center and to compensate for the size of the tube whereby upon assembly of said complementary segments by holding means engaging the shank portion along its length the tube may be held in accordance with the diameter of the tube by a pair of said fingers complementarily positioned in contacting engagement, holding said tube in mounted position upon said seat or saddle and held against displacement by said fingers within a range of sizes having normal variations as a result of the tube forming operations.

2.
