Abstract: A coupling for joining the open ends of unthreaded pipe sections is disclosed which includes a first coupling member adapted to be fitted over and adhered to the open end of one of the pipe sections and a second coupling member having a portion thereof fitted over and adhered to the open end of the other pipe section and a portion thereof adapted to be fitted on and adhered to the first coupling member. The first coupling member is designed so that the end thereof can be brought into abutting relationship with the open end of the pipe section containing the other coupling member while maintaining the longitudinal axis of both of the pipe sections parallel to each other at all times.

Abstract: A pipe-supporting clamp is disclosed in several embodiments adapted to be permanently embedded in the masonry floor of a building structure for supporting a pipe extending through the center of the clamp. The device has anchor means formed therewith which are surrounded by the masonry material to prevent movement of the device in the floor. A means is also provided adjacent one end of the device for forcing a portion of the interior wall of the device into engagement substantially all around the circumference of a portion of the pipe to clamp the pipe against movement within the device.
