ATTD RN EYB United States Patent ANTENNA MAST SUPPORT Otto Harrison Gilfry, Buena Park, Calif.

Application June 4, 1953, Serial No. 359,517

1 Claim. (Cl. 248-43) This invention relates to devices for mounting television and radio antenna masts and the like on a shingle roof, and in particular a clamp or clip having a base in the form of a tongue with V-shaped notches in the edges providing prongs adapted to provide gripping elements for holding the tongue particularly in composition shingles without danger of causing a leak in the roof.

The purpose of this invention is to provide mounting elements for holding masts and guy wires of antennas in which tongues of the devices are adapted to slip under shingles of a roof and securing the tongues in position without danger of leaks.

The conventional type of mast and guy wire mounting clamps are secured, preferably with nails extended through the material of a roof and with continual working of the parts resulting from wind causing vibration and other movements in a mast the nails work enlarged openings in the rooting material and these openings eventually develop into leaks. With this thought in mind this invention contemplates a mast and guy wire mounting clamps and clips having tongues with V-notches in the edges and nail openings therethrough whereby the tongues are adapted to be inserted under wood or composition shingles and are also adapted to be secured in position with nails and the like driven through the shingles and into rafters and other supporting elements below the shingles.

The object of this invention is, therefore, to provide mounting elements for retaining antenna masts and bracing clips on a shingle roof without causing a leak in the roof.

Another object of the invention is to provide mounting elements for retaining antennas and the like, particularly on shingle roofs, in which the elements are adapted to be installed on a roof after the construction of the roof is completed.

A further object of the invention is to provide mounting elements for retaining antenna masts and the like on a shingle roof in which the mounting elements are of simple and economical construction.

With these and other objects and advantages in view the invention embodies a U-clamp having a screw with a thumb nut thereon extended through anges at one side and a tongue having serrations in the edges and nail holes therethrough extended from the closed end of the clamp.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is an elevational view of the mast holding clamp with the tongue extended from the clamp shown in section and illustrating the use of the clamp on a roof, the roof also being shown in section.

Figure 2 is a plan view of the clamp with a tubular mast, which is shown in the clamp, in section..

Figure 3 is an elevational view showing the mast holding clamp in combination with guy wires and clips for securing the ends of the guy Wires.

2,735,639 Patented Feb. 21, 1956 "ice Figure 4 is a perspective view illustrating one of the clips for holding the guy wires.

Figure 5 is a plan view of a sealing plate adapted to be positioned over the tongue of the clamp for covering nail holes through the tongue.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved mast mounting clamp of this invention includes a support member 10 having a clamp formed with arms 11 and 12 extended from the upper end and having a tongue 13 extended from the lower end, a clip 14 having a tongue 15 and an upwardly extended flange 16 and a cover plate 17 having elongated slots 1S and 19 therein.

The tongue 13 of the clamp is provided with an opening 2t) for a lead-in wire of an antenna, nail holes 21 and 22 and V-shaped notches 23 and 25 providing prongs, as indicated by the numerals 2S and 26 and, as illustrated in Figure 1 the tongue 13 is adapted to be installed over the edges of shingles and covered by the plate 17 at the ridge of a roof. The tongue 13 is adapted to be secured in position as shown in Figure l with nails 27 that may be driven through the nail holes 21 and 22. lt will be understood that as many nail holes as may be desired may be provided in the tongue.

rhe arms 11 and 12 of the clamp are provided with flanges 28 and 29 through which a bolt 30 extends and the clamp is secured around a mast 31 with a wing or thumb nut 32 that is threaded on the bolt.

With the clamp formed of comparatively thin metal the parts may be bent to the angle of a root or to a suitable angle for mounting a mast or the like on a roof. In the design shown a lead-in strip or wire 33 may be carried in over the tongue of the clamp, as shown. It will be understood that the lead-in wire may also extend through the opening 20 or may be carried through the roof by suitable means.

As illustrated in Fig. 4 the tongue 15 of the clip 14 is provided with V- shaped notches 34 and 35 which provide barbs or prongs 36 and 37 and the ange 16 of the clip is provided with an opening 38 through which a guy wire, as indicated by the numeral 39 may be attached to the clip.

With the parts formed in this manner the tongues 13 and 15 may be inserted below the shingles 40, particularly as shown in Fig. 3 and with the parts in position nails or the like may be driven through the shingles and tongues.

The cover plate 17 is adapted to be slipped over the tongue 13 to provide a cover for the nail holes to prevent water working through the nail holes.

It will be understood that by these mounting elements a mast may be installed at the ridge or on the side of a roof and with the parts secured in position as disclosed the mast will be permanently secured in position.

Guy wires such as the wires 39 may extend from clips, such as the clip 14 to a collar 41 or to a fastening element of any other suitable type on a mast or the like.

It will be understood that modifications, within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

An antenna mast support comprising a leg and a tongue joined at one of their ends to provide a V-shaped support member, a U-clamp having a pair of arms to receive an antenna mast, said arms being provided with parallel lugs extending from the ends of the arms, said U-clamp being integral with one end portion oi the leg of said support and extended from the end portion of the leg at right angles thereto, a bolt having a wing nut thereon extended through the lugs, the tongue of said support having openings therethrough to receive an 4 antenna lead-in wire and fastening means and barbs on 1,917,809 Reimann July 11, 1933 the edges thereof to engage the shingles of a roof and 1,946,757 Parker Feb. 13, 1934 said tongue being positioned at one side of said clamp 2,200,435 Thrasher May 14, 1940 at an angle thereto. 2,294,624 Miller Sept. 1, 1942 5 2,356,085 Pfa, Jr. Aug. 15, 1944 References Cited 1n the file of thls patent FOREI GN PATENTS UNITED STATES PATENTS 184,654 Great Britain Aug. 24, 1922 753,942 Wallace Mar 8, 1904 189,339 switzerland Feb. 2s, 1937
