Coupling clamp and a method of manufacture therefor
First Claim
1. In a coupling device which is made from a single piece of a sheet metal or tubing blank and comprises an axially extending tubular body portion which defines a socket for axially receiving a transmission member, and two spaced-apart lugs which extend from said body portion and define an axially extending throughway slot in said body portion and are provided for receiving clamping means for urging said lugs toward each other for clamping said body portion onto said transmission member;
- the improvement comprising an integral tab on at least one of said lugs which tab extends directly toward said other lug a distance less than the width of said slot in a plane substantially perpendicular to said tubular body.

Abstract
Disclosed herein is a coupling clamp formed by shaping a sheet-metal blank or tube length and having an axially slotted hollow body (14) forming a socket for a shaft or other transmission member and having a lug (17) depending from either side of the slot (15), the lugs being pierced (18) for the passage of a bolt or the like by which the clamp can be tightened to bear radially onto a shaft, at least one of the lugs having at least one internal tab (13) extending at least part-way across the slot and shaped to bear radially onto a shaft on tightening the clamp.

5. In an assembly comprising a transmission member and a coupling device which coupling device is made from a single piece of a sheet metal or tubing blank and comprises an axially extending tubular body portion which defines a socket in which socket is coaxially engaged said transmission member, two spaced-apart lugs which extend from said body portion and define an axially extending throughway slot in said body portion, and clamping means combined with said lugs for urging said lugs toward each other and thereby clamping said body portion onto said transmission member;
- the improvement comprising an integral tab on at least one of said lugs which tab extends directly toward said other lug a distance less than the width of said slot in a plan substantially perpendicular to said tubular body, said tab defining an edge which bears on a part of the periphery of said transmission member when said body portion is clamped by said clamping means.
