Abstract
Abstract A mechanism for changing the direction of travel of a continuous and rapidly moving bendable rod through a substantial angle in the order of 90*. The mechanism consists of a power driven grooved guide wheel and a plurality of rotating closely adjacent smaller guide wheels located along a segment of the periphery of the main guide wheel about which the rod is to be turned. Some of the smaller guide wheels are slanted alternately with respect to the main guide wheel. The slanted wheels overlap each other so that over a given angular segment of the main guide wheel, there may be more positions of engagement of the smaller guide wheels with the rod thereby to maintain full control of the rod as its line of travel is changed and to insure complete delivery of the rod for its entire length to a rod collecting device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
Means for changing the direction of travel of a rapidly moving bendable rod, said means comprising a main grooved rotating wheel about which said rod passes as it changes direction and a plurality of rotatable smaller wheels positioned adjacent said main wheel for engaging and holding said rod against said main wheel as the rod direction changes, at least some of said smaller grooved wheels being alternately and oppositely slanted with respect to said main wheel and overlapping each other whereby the distance between successive rod engaging positions of said some smaller slanted grooved wheels with said main wheel is substantially less than the diameter of said slanted smaller wheels.
Claim 2
Dependent Claim
110 words
Means for changing the direction of travel of a rapidly moving bendable rod, said means comprising a main grooved rotating wheel about which said rod passes as it changes direction and a plurality of rotatable smaller wheels positioned adjacent said main wheel for engaging and holding said rod against said main wheel as the rod direction changes, at least some of said smaller grooved wheels being alternately and oppositely slanted with respect to said main wheel and overlapping each other whereby the distance between successive rod engaging positions of said some smaller slanted grooved wheels with said main wheel is substantially less than the diameter of said slanted smaller wheels.
Claim 3
Dependent Claim
19 words
Means as set forth in claim 1, the first of said smaller wheels being aligned with said main wheel.
Claim 4
Dependent Claim
21 words
Means as set forth in claim 1, said first and last of said smaller wheels being aligned with said main wheel.
Claim 5
Dependent Claim
21 words
Means as set forth in claim 3, all of said smaller wheels between the first and last being said slanted wheels.
Claim 6
Dependent Claim
27 words
Means as set forth in claim 1 and means for driving said main wheel at a peripheral speed not less than the delivered speed of said rod.
Claim 7
Dependent Claim
38 words
Means as set forth in claim 1 and means for causing rotation of said smaller wheels at the same peripheral speed as said main wheel when no rod is present between said main wheel and said smaller wheels.
Claim 8
Dependent Claim
22 words
Means as set forth in claim 1, the axes of said slanted wheels when extended intersecting the axis of said main wheel.
Claim 9
Dependent Claim
63 words
Means as set forth in claim 1, each of said smaller wheels mounted on a bearing carried shaft, each said bearing mounted on a support permitting movement of each said smaller wheel toward and away from said main wheel, and spring means resiliently holding each said smaller wheel against said main wheel in the absence of rod between said main and smaller wheels.
Claim 10
Dependent Claim
106 words
Means as set forth in claim 1, the first of said smaller wheels being aligned with said main wheel and having its axis parallel to the axis of the main wheel and aligned with a radius of said main wheel which is at a sufficient angular distance beyond the initial point of tangency of said rod with said main wheel to first engage the end of the rod and direct it into the bite between said first smaller wheel and said main wheel whereby the advancing rod will be continuously bent to a curvature corresponding substantially to the curvature of the circumference of said main wheel.
