Abstract
A technique for forming and mounting a handle which includes the steps of providing a channel-shaped body of metal with opposed flat lugs at its midportion, inserting a metal rod perpendicularly into the channel-shaped body in tangential surface contact with the inside surfaces of the lugs and in abutment with the inside wall surface or web of the body, mounting these interengaging parts horizontally in a holding jig provided adjacent the stationary lower electrode of an electric welder with the bottom lug engaged on the electrode, and lowering the other welding electrode into contact with the upper lug, so as to weld the lugs to the opposite sides of the rod at the tangential contact surfaces.

A method of forming and mounting a handle comprising the steps of:
- a. Providing a flat sheet of weldable metal with narrow, opposed imperforate flat lugs projecting from the midportions of the opposite side edges of the sheet;
- b. Forming the sheet into a channel with said lugs extending coplanar with the channel sides parallel to each other;
- c. Extending the end portion of a weldable cylindrical rod between said lugs perpendicularly to the channel to bring the end of the rod substantially into abutment with the web of the channel with diametrically opposite sides of the rod in tangential surface contact with the inside surfaces of the lugs;
- and
- d. Fusing the rod to said inside surfaces to form rigid bonds therewith.
A method of mounting a cross bar on a stem comprising the steps of:
- a. Forming the cross bar with a pair of spaced substantially flat imperforate lugs projecting therefrom;
- b. Inserting a cylindrical stem between said lugs and establishing tangential lineal contact of said stem with said lugs;
- c. Fusing said stem to said lugs by passing welding current through said lugs and stem.
