Abstract
Abstract This invention consists of an antenna supported by a vertically disposed shaft. The lower portion of the shaft extends through a hub and bearing that is integrally formed with the apex of the antenna shaft support and mechanism housing. The mechanism that rotates the aforesaid antenna comprises two horizontally disposed gears in mesh with one another. The lower portion of the antenna supporting shaft passes down through and is secured to the center of the largest of the two gears, the shaft being provided with a locking collar that is adapted to spring-loaded mechanism activated by mechanism connected to the upper end of a flexible shaft that terminates in and is secured to the center of the second of the two aforesaid gears, the second gear being smaller in diameter than the first mentioned gear. The lower end of the aforesaid flexible shaft is secured to a hand wheel that rotates the aforesaid antenna by means of this mechanism, as will hereinafter be described.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A manually rotated antenna, comprising an antenna mounted on the upper end of a vertically disposed shaft that has its lower end extending down through a supporting housing, structure located in said housing joining said antenna vertically disposed shaft and a flexible rotatable cable in operational engagement with said structure a hand operated wheel located on one other end of said flexible cable to rotate said antenna; said structure comprises a large and a small horizontally disposed gear in mesh, the large gear being secured to said antenna and the small gear being secured to the upper end of the said flexible shaft; and mechanism adapted to lock the said antenna at any desired place of rotation.
Claim 2
Dependent Claim
117 words
A manually rotated antenna, comprising an antenna mounted on the upper end of a vertically disposed shaft that has its lower end extending down through a supporting housing, structure located in said housing joining said antenna vertically disposed shaft and a flexible rotatable cable in operational engagement with said structure a hand operated wheel located on one other end of said flexible cable to rotate said antenna; said structure comprises a large and a small horizontally disposed gear in mesh, the large gear being secured to said antenna and the small gear being secured to the upper end of the said flexible shaft; and mechanism adapted to lock the said antenna at any desired place of rotation.
Claim 3
Dependent Claim
61 words
The invention of claim 1, wherein the said locking mechanism comprises a locking collar mounted on said shaft below said large gear and a lever in actuating contact with said locking collar and said small gear at the end of said flexible shaft, and means also in contact with said flexible shaft to lock and unlock said collar through said lever.
Claim 4
Dependent Claim
154 words
The invention of claim 2, wherein the mechanism for locking the said antenna consists of a locking collar that is mounted in a horizontal position on the first mentioned shaft below the large gear, the said locking collar having a plurality of equally and radially spaced recesses in the periphery thereof in any one recess of which projects one end of a horizontally disposed spring-loaded locking pin that has its other end secured to a horizontally disposed wire whose other end passes through an opening in the apex of a horizontally disposed V-shaped lever, the end of the said wire being secured to a ball in the said lever which passes through an opening in a supporting bracket, the lips of the said lever being adapted to activating contact with structure encompassing the upper portion of the said flexible cable whose vertical movement both locks and unlocks the rotating mechanism of the said invention.
Claim 5
Dependent Claim
119 words
The invention of claim 3, wherein the said structure that encompasses the said upper end of the said flexible cable consists of a tubular member having a plurality of vertically disposed and integrally formed and vertically spaced projections therein; and a horizontally disposed disc secured to the upper portion of the said flexible cable, the said disc being adapted to press up or down against the said projections by means of the vertical movement of the said tubular member, the action thus causing the periphery of the said tubular member to move the lips of the said horizontally disposed V-shaped lever and thus lock or unlock the said locking pin from the said locking collar of the said antenna.
Claim 6
Dependent Claim
100 words
A manually rotated antennae comprising a housing, an antennae, a shaft engaging said antennae and extending downwardly through said housing; a flexible shaft extending its one end also into said housing, a hand wheel in rotational engagement with the other end of said flexible shaft; a first gear mounted on said antennae shaft and a seconD gear in engagement with said first gear mounted on said one end of said flexible shaft; supporting means maintaining said flexible shaft gear in rotational engagement with said antennae shaft gear; and a locking mechanism for maintaining said gears fixed relative one to another.
Claim 7
Dependent Claim
100 words
A manually rotated antennae comprising a housing, an antennae, a shaft engaging said antennae and extending downwardly through said housing; a flexible shaft extending its one end also into said housing, a hand wheel in rotational engagement with the other end of said flexible shaft; a first gear mounted on said antennae shaft and a seconD gear in engagement with said first gear mounted on said one end of said flexible shaft; supporting means maintaining said flexible shaft gear in rotational engagement with said antennae shaft gear; and a locking mechanism for maintaining said gears fixed relative one to another.
