Patented; Jan. '27, 1931 EDWARD PENDLETON S'ADLER, or nonIsvILnn, KENTUCKY AERIAL-MAST, nnaoxnr Application fi1ed IJecember 20, 1927. Serial 80,241,422; if

This invention relates to improvements in means for supporting aerial masts on the roofs of houses or the like.

A prime object of this invention is to'provide an aerial mast bracket which may be firmly attached to a chimney or a building and adapted for supporting thereon an antenna mast. of any desired length.

A further object of this invention is to provide an aerial mast bracket, particularly adapted'for supporting an antenna mast adjacent a chimney or a building or other suitable projection thereon, thebracket being of simple and inexpensive construction and easily clamped into'firm position on the chimney, after which it is a simple matter to locate the mast in the receiving portions of the bracket.

Other objects of this invention will appear from the following detailed description of the device and as disclosed in the two sheets of drawings which are made a part of this specification.

In the drawings Figure 1 illustrates an elevational view of a chimney of a building having attached thereto the aerial mast bracket and disclosing the antenna mast in assembled relationship therewith. I

Figure 2 represents a top plan view of Figure 1.

Figure 3 illustrates a side elevational view of one of the, clamping members of the aerial mast bracket. a

ure 3.

Figure 6 represents, a fragmentary view of the connecting rod between the clamping members of the bracket, disclosing particularly the loop in the rod for receiving the antenna mast.

In the supporting bracket for receiving an antenna mast, according to this invention, it is preferred that numeral 1 designates a chimney of a building or any other suitable projection upon which an antenna mast may be located and upon which the aerial mast brackets described and claimed in this application Figure 5 illustrates a top plan View of Figmaybe used to advantage." Nume'raIs'fZja-nd 3 designate the main bodyportions of vthe clampingjmembers which may be madeof'any suitable material and properly formed for the purpose desired and preferablyhaving'arm portions '4 and 5 provided at the free ends thereof with suitable elements 6 and7, which are adapted to aid materially in firmly gripping the chimney" 1 or building projection. The gripping "or'clampingmembers 2 and 3 are provided, preferably with auxiliary arm members Sand 9 formed-insuch a manner that they will'co-operate with-the gripping arm members l and 5, when desired, in firmly clamping the bracket to the building projection or chimney' lt The

bracket members

2 and ,3 are further providedwith extensions 10 and ll-for receiving in looserelationship therein the free ends of a tension'and supporting rod 12, the ends of the rod 12 being threaded, as at'13 and 14;, to receive

tension nuts

15 and 16. The tension rod 12 may be made of any suitable material, such as wrought iron or the like and" is preferably provided with a loop 17 in which theantenna mast maybereceivedr i -In operation; He invention'provides an aerial mastbracket of simple "and ine'xpen sive construction which may be easily in stalled uponia suitable projection from a building, such as particularly a chimney. The device consists primarily of two clamps each partly encircling two corners of the chimney; or other projection; The two clamping portions are connected together by means of a tension rod; The clamps are merely placed on each side of the chimney, after which the rod maybe properly located in position and the gripping -members brought under tension by means of the threaded tension nuts oneach end of the rod. The tension should not be sufficient to decrease the diameter of the loop inthe 7 inserted in the loop portions 17 of the brack- IOU ets after they are properly located in position. It is apparent that tension may be brought around the mast 18 for holding it in posit-ion by tightening up of the

tension nuts

13 and 14, thereby drawing the loop portion 17 firmly around the antenna mast. The projections 6 and 7 extending from the

clamping members

2 and 3 are preferably somewhat pointed so that they may obtain a firm grip in the mortar between the bricks or other desirable position.

After installing the mast in the supports,

the aerial or antenna may be easilytightened by moving the bracket from one side of. the chimney to the other. This operation is easily accomplished by loosening the nuts on one side of the chimney and tightening the nuts on the other side.

A ball 19 is detachably connected with the top of the mast and provided with an eye portion 20, to which the end of the aerial Wire is adaptedto be leashed. The ball is preferably'madeof red porcelain, whichwill lessen the chance of being affected by lightning and will insure the Boardof Underwriters approval.

It is to be understood that substitutions and alterations maybe madetin the above disclosure, including the drawings, within the scope of the appended claims without affecting the merits of this invention.

What I claim is:

1. An aerial mast bracket comprising clamping members adapted to grip a supporting surface, a rod adjustably and slid ably mounted in each of said clamping members and having a'loop intermediate its ends, said loop adapted to support a mast therein, and means for tensioning said loop and said clamping members.

2. An aerial mast bracket comprising clamping members adapted to grip a supporting surface, a rod connected to said clamping members and having a'loop intermediate its ends, said loop adapted to support a mast therein, and means for tensioning said loop. I

3. An aerial mast bracket comprising clamping members adapted to grip a supporting surface, a rod connected to said clamping members and having a loop intermediate its ends, said loop adapted to support a mast therein, and means for tensioning said loop and said clamping members.

In'testimony whereof I affix my signature.
