Description: |
| "In making a joint by pouring molten metal about a pipe or like part it is the custom to employ a dam or joint-runner made of putty or clay or some such plastic material that is not injured by heat; but there are many objections to the use of such material, as the dam is not of a permanent materal in its nature and can be used but once and in one place. The object of my invention is to provide a portable joint-runner of a material not readily affected by heat or cold and one that can be used on different sizes of pipe and in all places where a joint-runner is needed..." |
