4 Claims. i

This invention relates to supporting devices and more particularly to an antenna mast supporting bracket for a television antenna or the like which is adapted to support the antenna adjacent the upper portion of a house or other building.

An object of this invention is to provide a novel supporting bracket for adjustably securing a television antenna or the like to the peak of the roof of a building such as a private home or the like, and which antenna bracket has means formed therewith for clamping engagement directly with the roof and adjacent portions or the building.

A further object or" this invention is to provide an antenna bracket having a threadedly adjustable clamping member with an angle plate swivelly mounted thereon for engagement with a building in a secure manner.

Still further objects of the invention reside in the provision of an antenna bracket that is strong,

durable, highly efficient in operation, simple in construction and. manufacture, capable of being secured to a building with a maximum of ease and convenience, and which bracket is relatively inexpensive.

These, together with the various ancillar objects of the invention which will become apparent as the following description proceeds are attained by this antenna mast supporting bracket, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a perspective view showing the bracket operatively supporting an antenna mast;

Figure 2 is a vertical sectional view of the antenna mast supporting bracket;

Figure 3 is an elevational view of the antenna mast supporting bracket;

Figure 4 is a top plan view of the invention;

Figure 5 is a perspective view of a modified form of the invention which is adapted for use on a house not having a gable; and

Figure 6 is a sectional detail of the antenna bracket as shown in Figure 5.

Briefly, and by way of introduction to the specification, it will be clear that the invention is especially well adapted for use on the peak at either end of a gable roof and that it is characterized, generally construed, by clamp means whereby a television antenna may be attached and supported wholly and directly from the selected peak comprising a rigid support member embodying an elongated vertical leg adapted to be disposed in spaced parallelism in respect to an end of the wall of said building, a horizontal leg joined with said vertical leg and adapted to extend at right angles from said vertical leg and to underlie the overhanging roof peak, horizontally disposed yoke means carried by the upper end of said vertical leg, said yoke means being U-shaped in plan and having a pair of independent spaced parallel arm portions adapted to straddle the ridge of the roof with said ridge projecting through the space between said arm portions, an end thrust and clamping plate, a jack screw swivelly connected with said plate, screw-threaded means operatively and adjustably mounting said jack screw on said horizontal leg, and means mounted on said vertical leg for the attachment thereto of an antenna mast.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral :5 generally designates a portion of a house having a peaked roof and a suitable gable on which the antenna bracket, generally designated by reference numeral IE, is adapted to be secured to support suitable television antenna or the like as indicated at M.

The antenna bracket 22 includes a principal supporting member it which is of substantially L-shape having a vertically extending leg 20 and an arm 22 extending at substantially right angles to the leg Zil.

Welded or otherwise secured to the upper portion or" the leg 29 is the eight portion of a substantially U-shaped member 24 which has depending therefrom screws as for working engagement into the tile, shingle, or other pitch type or equivalent roof forming a part of the building It). Also welded to the leg 2e are vertically spaced rings 23 and 36 which have fitted therein screws 32 and 34 which, in combination with lock nuts 36 and 38, provide means for securely holding the mast of the antenna M in an adjusted position relative thereto.

Threadedly engaged in a nut 40, welded to the arm 22, is a threaded jack screw 2 which is provided with a handle M at one end. The upper end of the screw 42 is provided with a swivel joint &6 for swivelly or pivotally mounting an angular end thrust plate 43 which when the arms of the U-shaped member 24 are positioned at either side of the fixed roof and when the handle is turned actuating the clamping screw 32, will engage the gable of the building H3 in a secure manner without digging into the wood. As can be readily seen, the screw 34 in engagement with the nut 38 provides ready means for attaching a ground line to the antenna.

Referring now to the'form of theinvention' as shown in Figure 5 it will be seen that the generally L-shaped supporting member 60 of this form of the invention also embodies a vertical leg designated by reference numeral 62 with the arm 66 extending at a convenient an angle thereto. A clamping or jack screw 68 is likewise provided with a handle and has the swivelled angle plate 12 pivotally mounted relative thereto. However, the angle plate 12 is provided with a substantially horizontal flange portion it and a substantially vertically extending flange portion 16 through which apertures 18 can be drilled for use in enabling screws 80 to be emplaced and engaged in the side of the building when the building is not provided with an overhanging peak. However, it is quite possible to permit the angle plate to become inserted under a shingle or the like thus eliminating the need of the screws 89. Obviously the form of the invention as indicated at 62 is provided with a U-shaped member 82 so that proper clamping relationship between the jack screw 88 and the U-shaped member 82 may be had.

Proper care should be given to the mechanical stability of the antenna and its support. Where located on the roofs of buildings the antenna and supporting guys, if any, should not be located so as to interfere with operations of the fire department or where liable to cross with electrical lines. In the instant installation no guy wires are obviously necessary and since the vertical leg of the L-shaped member is relatively long it provides a satisfactory foundational base and stabilizer for the portion of the antenna mast which lies alongside it, as is evident. Also, the two spaced apart rings or collars make it possible to attach the mast on the ground before the over-all mount is carried to its place of installation or, it is permissible to simply pass the mast up through the rings or collars after the bracket means is anchored and this saves time in the installation steps, as will be clear to persons skilled in the art to which the invention relates. The three-point contact feature is important and when the jack screw is tightened up the complemental portions are under tension and effective clamping results are virtually assured.

Since from the foregoing the construction and advantages of this antenna bracket are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiments shown and described, but all suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.

Having described the invention. what is claimed as new is:

1. For use on an overhanging peak at either end of a gable roof or equivalent pitch roof construction, means for supporting the pole of an antenna directly from said roof, instead of on a chimney, as usual, said means comprising a substantially L-shaped member embodying a vertical long leg and a horizontal short leg, a horizontally disposed substantially U-shaped ridge saddle embodying a bight portion and arm portions, said arm portions being at right angles to said long leg and adapted to straddle and rest firmly against the inclined portions of the roof on opposite sides of the ridge of said roof, said bight portion being secured intermediate its ends to the upper end portion of said long leg, anti-slipping members mounted on the free end portions of said arms and adapted to rest against coacting portions of said roof, nut means rigidly secured to the free end of the short leg, a jack screw threaded through said nut means and having a handle at one end and an angle iron plate at the opposite end, said plate being adjustably mounted on said jack screw, and pole embracing rings mounted at vertically spaced points on said long leg and provided with set screws.
