Abstract
Abstract A universal worm gear box capable of multiple selection assembly and gear ratios from a small number of components, wherein there is a hollow worm-rotated hub to drivingly receive a screw shaft in selective position and motion relationship to the hollow hub and a screw follower nut, and means for selectively attaching various anchoring or connecting linkages in different combinations and in different indexed positions of rotation about the longitudinal axis of the hollow hub.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
154 words
A universal gear box system for converting rotary movement to linear forces wherein the improvement comprises a gear box including a housing having opposite open side portions and having rotary-to-linear motion conversion means therein, the housing having a hollow rotary hub for the reception of and driving connection with said rotary-to-linear conversion means extending through at least one of said opposite open side portions, the housing having opposite flat faces about said open side portions with a plurality of arrangements of securing means equally spaced about each of the open side portions, and anchor members for opposing said linear forces having securing means complementary to the securing means of said open side portions and releasably securable thereto on either side of the housing in selected positions rotationally about the open side portions, said anchor members having means independent of their securing means for mounting the anchor members and gear box housing against transitional movement.
