AERIAL SUPPORT.

Application filed April 23, 1927. Serial No. 186,146.

This invention relates to a support for aerials such as used for radio reception, one

of the objects of the invention being to provide a support which can be connected readily to a chimney or other similar upstanding structure on a building, the same being mounted for adjustment and being easily applied to or removed from the chimney or the like.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is an elevation showing an aerial supported by means of devices such as constitutes the present invention.

Figure 2 is a section on line 22, Figure 1. Figure 3 is a plan view of the aerial support, the mast being in section.

Referring to the figures by characters of 80 reference 1 designates a collar provided at the center of a yoke 2, this yoke being provided with downturned arms 3 and 4. The arm 4 has an inturned terminal 5 while the arm 3 is provided with a binding screw 6 alining with the inturned portion 5. Legs 7 are extended laterally and downwardly from a sleeve 10 supported by collar 1 and in a plane at right angles to the plane occupied by the arms 3 and 4, these legs being formed with feet 8 adapted to rest upon the chimney C or other structure used for holdin the support. A tubular mast 9 is extende into the sleeve 10 and this sleeve has a coupling indicated generally at 11. Sleeve 10 is extended adjustably within the collar 1 where it is held by a set screw 12. If desired, and as shown at the right of Figure 1 and in Figure 3, the yoke 13, which corresponds with the yoke 2, can be formed with an extension arm 14 having an eye 15. In this eye is seated a tubular insulator 16 through which a lead-in wire L can be extended.

In practice two of these supports are preferably used, each being connected to a chimney or other similar projecting portion of a building. The yoke is placed with the arms 3 and 4 at opposite sides of the chimney C and by tightening the screw 6 said chimney or other structure will be tightly gripped. It is designed to have the parts so proportioned that when the yoke is thus located the feet 8 of the legs 7 will rest on the chimney as shown. The sleeve 1.0 can be adjusted vertically so as to bring the mast 9 to a desired elevation. Thereafter by tightening the setscrew 12, these parts can be held against relative movement. The aerial A is supported between the mast in the usual or any preferred manner with the leadin wire L extending therefrom.

Obviously this mechanism can be used on different kinds of roofs and while it is preferred to attach the yokes to the chimneys of a building, it is to be understood that they can also be applied to'any other upwardl projecting portion capable of being strad led by the yokes.

As the legs 7 are connected to the sleeve 10 said sleeve, when adjusted longitudinally relative to the yoke 2, can bring the feet 8 where they will rest firmly upon the chimney Cor the like. The coupling 11 of course permits the mast 9 to be tightly clamped in the sleeve, thereby permitting longitudinal adjustment of the mast relative to the sleeve.

Although this structure has been shown as designed primarily for use on chimneys it is to be understood that it can be connected to coping walls, to ridge boards, and at other places found most convenient.

Whatis claimed is:

1. An aerial support including a yoke having depending arms, cooperating means upon the arms for clamping upon structures of different sizes for holding the yoke thereto, a sleeve adjustably mounted Within the yoke, means carried by the sleeve for bearmg downwardly on the engaged structure to hold the yokeagainst tilting, and a mast carried by the sleeve.

2. An aerial support including a yoke having depending arms, cooperating means on the arms for clamping upon structures of different sizes to hold the yoke thereto, a sleeve adjustably mounted within the yoke, means carried by the sleeve for bearing downwardly on the engaged structure to hold the yoke against tilting, and a. mast adjustably connected to the sleeve.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

EDWARD H. CONSIDINE.
