Abstract
Abstract An orthogonal line generator is provided which comprises a combination of a straight line generator and a geneva mechanism. The straight line generator is a rotating system of two equal length arms. A first or base arm rotates about one of its ends while a secondary arm pivoted on the other end of the base arm rotates in the opposite direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
An orthogonal line generator comprising: a secondary arm and a secondary arm; said secondary arm being fixed at one end to a first shaft journaled in one end of said base arm; a driven sprocket gear attached to the other end of said first shaft; a second shaft attached to the opposite end of said base arm; a first drive pinion attached to the other end of said second shaft; a third shaft attached to a second drive pinion in mesh with said first drive pinion; a geneva drive gear attached to the other end of said third shaft; a hollow shaft journaled on said second shaft; said hollow shaft having a geneva driven gear fastened on one end and a sprocket drive gear mounted on the other end; a drive chain connecting said drive sprocket and said driven sprocket; and tensioning means for said drive chain including an idler sprocket adjustably mounted on said second arm.
Claim 2
Dependent Claim
157 words
An orthogonal line generator comprising: a secondary arm and a secondary arm; said secondary arm being fixed at one end to a first shaft journaled in one end of said base arm; a driven sprocket gear attached to the other end of said first shaft; a second shaft attached to the opposite end of said base arm; a first drive pinion attached to the other end of said second shaft; a third shaft attached to a second drive pinion in mesh with said first drive pinion; a geneva drive gear attached to the other end of said third shaft; a hollow shaft journaled on said second shaft; said hollow shaft having a geneva driven gear fastened on one end and a sprocket drive gear mounted on the other end; a drive chain connecting said drive sprocket and said driven sprocket; and tensioning means for said drive chain including an idler sprocket adjustably mounted on said second arm.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein said geneva mechanism causes one quarter revolution of said sprocket drive gear for every one revolution of said third shaft.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein said first drive pinion has 40 teeth and said second drive pinion has 50 teeth.
