Tony Helm universal joint (Garage Journal)

Description: |
| " This invention relates to a universal joint, and more particularly to such joints that can be made in groups having a plurality of units for increasing or varying the angle between the axis of the driving element and the axis of the driven element. The present invention is an improvement over that disclosed in the patent to Helm & Derleg No. 2,760,358, granted August 28, 1956.
In the use of mechanic's tools, it often occurs that a considerable angle exists between the axis of the driven element and the available position for the axis of the driving element. By the use of the present invention I have made it possible to transmit such driving force through angles greater and less than three hundred and sixty degrees. "
The patent number appearing on a known example marked "THOR" reflects manufacture for distribution by Independent Pneumatic Tool Co. (Aurora, IL). Also distributed by Snap-On. An extensive "GARAGE JOURNAL" discussion about the tool provides context and additional details. |
