Abstract

Meshing radially serrated annular pads projecting from the meeting surfaces of two members of a belt drive tensioning device to provide locked incremental angular adjustment of the members are formed by depressing an annular indentation in each member in the side thereof opposite its meeting side so as to cold flow metal to the meeting side thereof and in coining a serrated annulus in the metal thus transferred.

Claims

1. The method of providing a locked incremental angularly adjustable connection of two flat metal members having meeting sides which consists in;

depressing separately an annular indentation in that side of each member opposite its meeting side to form annular pads having end faces projecting from the meeting sides thereof, coining radial serrations in the end faces of said annular pads, then meshing the serrations thus formed on the end faces of the pads of said members, and in detachably connecting said meshed members by a bolt passing through apertures in said members central of said annular pads.
