Abstract

Abstract Coacting driving gears are disclosed, in certain embodiments each of the gears having an annular series of teeth and cavities for receiving the teeth, these teeth and cavities being alternately arranged and identically and evenly spaced in each of the series on the two gears so that the gears in driving relationship alternately have a tooth of a first of the gears entering into a cavity in the second of the gears, and immediately thereafter a tooth in the second gear enters into a cavity in the first gear. The axes of the two gears may be coplanar or with their axes arranged at 90* and with the axes of the coacting driving elements either arranged at ninety degrees to each other, or at a 45* arrangement. In certain embodiments where the axes of the gears are arranged at 90*, all of the teeth may be on one of the gears and all of the cavities may be on the other of the gears.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 149 words
Coacting driving and driven gears comprising on each of said gears an annular series of pin shape teeth and cavities for receiving said teeth, said teeth and said cavities being alternately arranged and identically and evenly spaced in each of said series, each of said teeth being press fitted into an opening in its associated gear, each of said cavities being cup shape having a bottom in its associated gear, and said gear in driving relationship arranged each on its coacting concentric shaft so that a tooth of a first of said gears enters snugly into a cavity in a second of said gears and immediately thereafter a tooth in said second gear enters snugly into a cavity in said first gear, whereby neither of said gears can creep longitudinally of its associated shaft because of the continuous engagement of some of said teeth in some of said cavities.
Claim 2
Dependent Claim 149 words
Coacting driving and driven gears comprising on each of said gears an annular series of pin shape teeth and cavities for receiving said teeth, said teeth and said cavities being alternately arranged and identically and evenly spaced in each of said series, each of said teeth being press fitted into an opening in its associated gear, each of said cavities being cup shape having a bottom in its associated gear, and said gear in driving relationship arranged each on its coacting concentric shaft so that a tooth of a first of said gears enters snugly into a cavity in a second of said gears and immediately thereafter a tooth in said second gear enters snugly into a cavity in said first gear, whereby neither of said gears can creep longitudinally of its associated shaft because of the continuous engagement of some of said teeth in some of said cavities.
