Filed Feb. 7, 1953 mit Patented Aug. 22, 1933y s'rrsfs M'AERIAL sUPron'rV mRobert G. Flor, Brooklyn, N. Y. Application February 7, 1933. ,serial No. 655,655y Y 4 claims. (ci. 18e-'31).

This invention relates to an aerial support and has for an object `to provide an improved aerial support which is to be placed inthe top of the chimney flue without necessitating any holey in the mason work ofthe chimney. e

A further object of this invention is to provide an aerial support which may be quickly and Yeasily attached and detached to the inside of the chimney flue thereby making thev placing of 'an aerial on the roof of a home, apartment or other building a simple and easy proposition and cutting down the insulation work to a minimum.

A further advantage of the use of the aerial support constituting this invention is in houses or apartments having more than a single lfamily and having an individual chimney ior each iamily whereby each tenant may set up his own aerialv support into his own chimney flue, thereby eliminating the necessity or the temptation for the other tenant to make use of the same aerial support when the original installer is unable to positively identify hisaerial as his own work. With this invention by placing his own vaerial in his own chimney flue, he positively identiiies the same and avoids the objection of having other tenants place their aerials on his support with" theconsequent detriment to his radio reception.

With the foregoing and other objectsin View, as will hereinafter become apparent, this inven- 1 tion comprises the constructions, combinations and arrangements of parts, hereinafter set forth, disclosed and shown on the accompanying drawing. In this drawing, l

Figure 1 is an elevation view showing this invention applied to a house chimney flue. Y

Figure 5 is a rnodicationr of the invention showing a square pole and square bracket.

Figure 6 is a modification of the invention showing a pole of an l. shape with brackets.

There is shown at 19 an aerial mast which is supported in accordance with this invention for Vsupporting the aerial 11, being connected thereto by the insulator 12. AThe aerial mast i0 is secured within the flue pipe 13 of the chimney 14 without making any holes yin the flue pipefor mason work of the chimney. A lower clamp 15 and an upper clamp 16 are each secured about the aerial mast 10 by means of bolts and nuts 17', the bolts 17 also serving for attaching the legs 18 and 19 of this support" theretojthe legs r18 and 19 Abeing bolted'togethe'r as at 2G. The leg 19 is in turn composed oian upper arm 21 and a lower arm 22 pivotallyV secured together by the bolt and nut 23.

ArgENr oFVIFIcE l The bolt 23 also serves asa securing'means'for the Vflanged washer 24 through which passes the Ythreaded end 25 of a tie rod 26, the other end or" the tie rod 26 being pivotally connected to about the center of the lower leg 18 by having its end 2'7 turned through an appropriately placed aperture in the `leg 18,r A wing nutv 28, placed on the threaded end k25 of the tie rod 26, serves to cause the two arms 2l-and22 or leg 19 to approach anangle of idegrees to each other as the Wingnut is tightened down on'the tie rod 26.

To install thissupport in the iiue pipe 13 of Y the chimney 14 the wing nut 28 is unthreaded until the arms 21 and 22 are at considerably less than 180 degrees to each other as shown at 21 and 22', and the bolt 20 is moved totheposition 20' causing the distance between the opposite sides of the aerial mast 10 and the outside of the bolt 20 to be less than the width of the iiue pipe 13. When in thisposition, the mast and the attached leg 18 and 19 are placed within the ue pipe 13. The wing nut 28 'is then tightened down `from the position 28 causing the arms 21 Y -and 22 oi leg 19 to approach but'notreach an angle of 180 degrees and causing the pivotal connection 26 of the legs 18 and 19 to abut against the opposite sides of the iiue, pipe 13 while the back of the clamps 15 and 16 about the aerial mast 10 are pressed against the first side of the iiue pipe 13. As will be observed, in this tightened position the legs 18 and 19 and the mast 10 substantially form a triangle vwith one point placed against one Vsideroi the chimney rlue and the other two points placed againstthe opposite side of the chimney flue, thereby serving to securely hold the aerial mast- 1() in the desired position. Although the aerial mast 10 has been shownin Figures 1 to 4 as being a solid, round element, it is obvious that the aerial mastmay be of any desired cross section, but in Figure 5 an aerial mast 30 vhas been 19, it being obvious of course that a clamp as shown in 31 might equally be used with an aerial mast 32 which is L-shaped in cross section.

The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is notl to be considered limited to the exact form disclosed, and that changes may be made therein within the scope of what is claimed without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention,` what is claimed is:

l. A radio aerial support including a mast and a holder for said mast, said holder consisting of a pair of legs pivotally clamped to said mast and to each other, one of said'le'gs comprising a pair of arms, pivotedrto each other at an angle of less than 180 degrees and means securing the pivotal point of said arm to said other leg thus causing the angle between said pivoted arms to approach 180 degrees andfso causing the distance between the pivotal point of saidleg and said mast to become greater whereby when said -sup-Y port is placed in a pipe, said mast will be held against one side of said pipe while said pivotal connection betwen said legs will be braced against causing the angle between said pivotedv arms to approach 180 degrees and so causing the distance between the pivotal point of said leg and said mast to become greater whereby when said sup- Y to said other leg, a angedwasher pivotally sen cured to said pivoted point, said tie rod passing through said flanged Washer, and a nut threaded on the end of said tie rod to bear against said '7 flange washer.

3. A radio aerial support adapted to be secured withinV a pipe comprising an aerial mast and a pair of legs pivotally clamped to said mast and 7 to each other, one of said legs comprising a pair of arms pivoted to each other at considerablyV less than degrees, andmeans secured to said angle of 180 `degrees and thereby causing the pivotal connection between said legs to increase the distance from the aerial mast.

V 1. A mast support for securing a mastwithin a Vother leg 'for causing said arms to approach an ico pipe comprising a pair or" clamps adapted'tobe secured to said mast, a pair of braces. hinged to said clamps and to each other, one of said braces comprising a pair of arms hinged to each other at an angle, and means for causing the angle between said arms to approach a straight angle to thereby extend the hinged connection between said braces. s
