Abstract

A cast iron pipe hanger clamp having a solid body with upper and lower jaws projecting from one side, and a boss projecting from the center of the opposite side and braced by upper and lower pairs of spaced flanges. The boss has a threaded bore with jam threads to receive a threaded pipe hanger rod between the spaced flanges, the load of the supported weight being distributed and loading the upper flanges in tension. A setscrew in one jaw locks the clamp in position and loads all four flanges in compression, reducing or eliminating tension load in the upper flanges.

Claims

1. An integral cast iron pipe hanger clamp having a body portion with spaced jaws projecting in one direction from one side thereof, one of said jaws having an opening for a setscrew to secure the clamp to a supporting beam, wherein the improvement comprises a boss projecting in the opposite direction from the center of the other side of said body portion, and upper and lower pairs of spaced flanges extending from the side of said boss to said other side of said body portion, said boss having an opening between said flanges to receive a pipe hanger rod.

2. A pipe hanger clamp as set forth in claim 1 in which the opening in said boss is internally threaded with the threads terminating in jam threads adjacent one face of said boss.
