Excerpt from Oxygen Mine Rescue Apparatus and Physiological Effects on Users As the most effective means of putting into concrete form and of testing the feasibility of the recommendations of this report, the Bureau of Mines has attempted to develop an apparatus along the physiological lines for which it calls. During the past two years 7. E. Gibbs, an experienced mechanical engineer, has been at work for the bureau on this problem. Mr. Gibbs, aided by the advice and cooperation of the authors of this report, has produced an apparatus which, in experimental tests, has shown itself superior to the older types, but which has still to be subjected to further tests in service. Its principal features have been patented for the Bureau of Mines, and, if finally successful, will be made available for general use.
