1 Claim. (Cl. 18913) This invention relates to a new and improved tower for supporting a television antenna, or for a similar purpose.

One object of the invention is to provide a novel tower which is s'ufiiciently rigid to require no guy wires yet sufficiently yieldable to avoid breakage under wind pressure.

Another object of the invention is to provide a tower construction from elongated prefabricated sections which may be easily assembled and attached to each other.

A further object is to so proportion the sections that the tower will decrease in diameter from its lower to its upper end.

A still further object is to so proportion the sections that they may be compactly nested into an assembly no longer than the sections themselves, thereby facilitating packaging, shipment and delivery.

Yet another object of the invention is to provide a novel construction which may be expeditiously manufactured and profitably sold at a fair price.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing, and particularly claimed.

In the drawing:

Figure 1 is a diagram showing the improved tower;

Figure 2 is a side elevation of the lower tower section showing the Way of anchoring it to the ground and also showing portions of the next section attached to said lower section;

Figure 3 is a horizontal sectional view on line 3--3 of Figure 2; and

Figure 4 is a diagram showing the sections nested.

The drawing illustrates the preferred construction, and while that construction will be rather specifically described, it is to be understood that minor variations may be made without departing from the spirit and scope of the invention as claimed.

.A six-section tower has been shown, the six sections being generally denoted at 5, 6, 7, 8, 9, and 10. These sections are of difierent diameters which gradually decrease from the lower end of the tower to the upper end thereof, permitting nesting of the sections prior to erection as illustrated in Figure 4 and imparting an upwardly tapered form to the tower when erected as illustrated in Figure 1. All of the sections are identical except for diameter and said sections are preferably all of the same length. The lower section 5 has been shown in detail and a description of this section will sufiice.

Three vertical corner members 11 are provided extending from end to end of the section 5, said corner members being uniformly spaced around the 12 as shown in Figure 3. At intervals, those corner members are connected byhorizontal tie bars 13 which are riveted or otherwise secured thereto, as indicated at 14. The corner members 11 are of tubular metal stock and the tie bars 13 are preferably metal channels with their ends flattened and then curved to provide seats 15 engaging said corner members.

The major portions of the lengths of the corner members 11 are parallel with the axis 12. The upper portions 16 of said corner members, however, incline toward the axis 12, from substantially the elevation of next to the uppermost series of tie bars 13, substantially to the elevation of said uppermost series of tie bars. From this latter elevation, the corner members 13'extend again vertically to the upper extremities of said corner members, as shown at 17. The lower ends 18 of the corner members 11 are expanded to impart an internal diameter to them equal to the external diameter of said corner members. Both ends 17 and 18 of each corner bar 11 are formed with suitably placed bolt holes 19.

The various sections 5 to 10 are connected with each other on the ground by telescoping their ends 17 and 18 and extending bolts 20 through the bolt holes 19 as seen at the upper end of Figure 2.

The entire tower is anchored to the ground after erection by engaging the expanded lower ends 18 of the corner members 13 with anchors 21 embedded in concrete 22 and bolting said ends 18 to said anchors, as seen at 23 at the lower end of Figure 2. The concrete 22 may be a single mass extending a safe distance into the ground, or three separate masses.

It will be seen from the foregoing that a simple and inexpensive, yet a highly desirable sectional tower has been provided, which will attain the desired ends, and while preferences have been disclosed, attention is again invited to the possibility of making minor variations within the scope of the invention as claimed.

What is claimed is:

A tower structure comprising a group of separate units connected together in end to end relationship, each of said units comprising a plurality of spaced, vertically disposed, elongated corner members, said corner members being connected by a plurality of transverse brace members which extend between said corner members and with said corner members define the sides of said tower, each of said units further having said corner members shaped to define a unit having a lower, elongated, straight portion, an inwardly directed, relatively short, tapered intermediate portion and a short, reduced straight upper neck portion, said corresponding portions of connected units being parallel to each other, the base dimensions of each successive unit of the group being equal to the dimensions of the neck portion of the next'lower unit and of lesser outside dimensions that the inside dimensions of said next lower unit, whereby said group of units forming a tower may be nested for shipment by telescoping each next lower unit over its next upper unit.
