rlhis invention relates to an antenna support of that type for positioning on roofs constructed of sheet metal plate provided with interlocking flanges, and has for its object to provide, in a manner as hereinafter set forth, a support of the class referred to capable of being secured ina stationary manner upon the roof without impairing the latter to any extent whatsoever.

A. further object of the invention is to provino, in a manner as hereinafter'set forth, an antenna support fo positioning upon roofs constructed from sheet metal plates provided with interlocking flanges and with the support so constructed and arranged whereby it is secured in an upright position relative to the roof without the employment of holdfast devices such as nails, which impair the roof to an extent to result in leakage.

A further object of the invention is to provide, in a manner as hereinafter set forth, an antenna support for positioning` on roofs constructed of sheet metal plate provided with interlocking flanges and with the antenna support including means to permit of the adjustment thereof to enable it to be employed in a satisfactory manner upon sloping roofs.

Further objects of the invention are to provide, in a manner as hereinafter set forth, an antenna support which is simple in its construction and arrangement, strong, durable, compact, adjustable, thoroughly eilicient in its use, conveniently set up, readily assembled and comparatively inexpensive to manufacture.

With the foregoing and other objects in view theinvention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

, ln the drawings wherein like reference characters i denote corresponding parts throughout the several views y Figure l is an elevation of an antenna supportv in accordance with this invention and illustrating an` antenna connected therewith and further the support positioned upon, a roof formedof interlocking metallic sheets.

I Figure 2is a top plan view of a pair of antenna supports inaccordance with this vention showing the adaptation thereof with respect to an antenna, the latter being broken away and also showing the supports mounted upon a roof constructed of interlocking flanged metallic sheets, the roof being broken away- Figure 3 is a. fragmentary view partly in section and in side elevation illustrating the base of the support mounted upon the roof.

Figure 4 is a section on line 4.4, Figure 3.

Figure 5 is a side elevation of one of the guy'ropes, cable or wire couplingmembers showing the adaptation thereof with respect to the interlocking flanges of a pair of metallic plates from which the roof is formed. l

Figure 6 is a section on line 6 6, Figure 5.

An antenna support, in accordance with this invention, includes a rectangular base l formed fromy any suitable material, preferably wood. The base lis of the desired height and is also of a length greater than the dis tance between a pair of interlocking spaced, opposed flanges 2, 3 of the metal plates ofthe roof il. The base l, centrally of its upper face, is formed with a socket' of a depth less than thel height of the base l. Mounted in the socket 5 is a post 6 formed of any suitable material and of the desired height. The base 1 kin p'roximity to each end thereof has its lower face provided with a transverse groove 7 having a convexed top wall 8. The distance between the grooves 7 is such that when the base l is mounted in position the grooves will be arranged over and in alignment with the interlocked flanges 2, 3.

The base 1 in proximity to each end thereo'l is formed with a pair of vertically disposed, aligning spaced openings 9, which terminate at their lower ends in the grooves 7. Ex-

tending upwardly through the openings 9, 10 are bolts 11, 12 respectively. The heads 13 of the bolts are arranged at the lower ends of the latter. The bolts extend a substantial distance above the upper face of the base 1 and carry washers 14 and clamping nuts 15.

Associated with each pair of bolts and extending into a groove 7 is an inverted, U- shaped connecting member 16 of a length greater than the width of base 1 and which projects a substantial distance beyond-each side face of base 1. The couplingl memberis mounted on an interlocking flange 2 orfand is formed at its bottom with oppositely extending flanges 17. The top of the connecting member 16 at a point between its vertical median and one end is formed with an opening 18 and at a pointbetween its vertical median and its other end is provided with an` opening 19. The bolts 9, 10 extend upwardly through the openings 18, 19 respectively and the heads 13 of the pair of bolts abut against the inner face of the top of the connecting member 16. The convexed wall 8 seats on the upper face of the top of the connecting member 16 and permits of the base l being secured level or squared with respect to the interlocking flanges 2 or 3 when the flanges incline downwardly in either direction. The connecting member 16 will extend in the same direction as the interlocking flanges 2 or 3, but when the base 1 is clamped to member 16 it will be arranged level, and this level position is had at all times by the convexed walls 8 in connection with the bolts 9 and 10, as one of the bolts will extend a greater distance above the base 1 to clamp a portion of the walls 8 against members 16 to secure base 1 in level position. With respect to the manner in which the convexed walls 8 and bolts 9, 10 functionto maintain the base 1 level when it is mounted on a sloping roof attention is directed to Figure Zl.

The support includes a series of coupling members and a series of guy wires, and by way of example, each series is shown as consisting of four coupling members or guy Wires, but this number can be decreased if desired. As shown, the coupling members and guy wires are arranged in pairs. One pair of coupling members is spaced rearwardly from the base 1 and one pair of guy wires extends rearwardly from post 6. The other pair of coupling members is spaced forwardly of base 1 and the other pair of guy wires extend forwardly from post 6. The guy Wires are disposed at an inclination Vwith respect to post 6 and have their other ends secured to post 6 near its upper end as at 17. The guy wires which extend forwardlyfrom post 6 are indicated at 18 andthe guy wires which extend rearwardly from post 6 are indicated at 19. The coupling members which are spaced forwardly from base 1 are indicated at 20. The coupling members which are arranged rearwardly from base 1 are indicated at 21. The guy wires 18 extend rearwardly and at an upward inclination from the coupling members 20. The guy wires 19 extend forwardly and at an upward inclination from coupling members 21. Each guy wire can be a wire, cable r rope, or a thin chain and which is termed a bracing element. Each guy wire has its lower end tixedly secured to a coupling member.

Each coupling member consists of an ovalshaped, hollow body portion 22 split at its botv.tomas lit-,23 and formed of resilient material.

VThe body portion 22 is reinforced by an ontwardly directed flange at each side thereol. The sides of the body portion 22 are indicated at 25, 26 and are formed with aligning openings 27. Extending through the aligning openings 27 a headed clamping bolt 28, which carries a clamping nut 29. The interloclred flanges of the metallic sheets from which the rool1 -1 is provided are formed with an-overapped part, indicated at 29, Figure 6, and which is ol" less height than the height olf the joint when it is completed. The overlapped part 29 provides a ridge or shoulder 30 on one side of the interloclied flanges and said shoulder 30 is spaced a distance above the upper face of the roof e. See Figure 6. The interlocked flanges are extended up into the body portion 22 and one side of the latter engages under the shoulder 30. As illus-- trated in Figure 6 the free end of side 25 engages under the shoulder 30 and abuts one side oi" the joint. After the body portion 22 is in such position the nut 29 is screwed home to tightly clamp the member 24 to the interlocking flanges and which maintains the clamping member stationary. As a guy wire connected to the coupling member it is held in bracing position relative to the pole.

The manner of connecting the support to the root vdispenses with the employment oi holdiast devices generally employed for securing an antenna pole in position and such holdfast devices impair or aperture the root and the result is that the root begins to leak, but by settingl up the support in the manner as herein stated such objection is not present. rlhe base 1 is positioned a substantial distance above the roof so that the passage oi water thereunder is not arrested or pi.ev(\,nted, as there is sull'icientclearance for such purpose between the lower face ot the' base l and the upper face otl the rool el.

In Figure 1 of the drawings a pair oi; autenna supports, in :uxcorilance with this iuvention are generally indicated at 81. 32 and which have connected to their upper ends the antenna or aerial 33.
