THE STANDARD HOSE COUPLING

THE STANDARD HOSE COUPLING

Last week a short history of the progress made in the adoption of a standard hose coupling was printed in this journal. It showed that since 1872 the subject has been before the fire engineers of this country but that comparatively little has been done to bring about the selection of a universal thread until 1879, when a six-thread to the inch standard was adopted. A change, however, to 7 1/2 threads to the inch was proposed at the Springfield convention in 1891 and this was finally decided upon and approved at the Duluth convention of the I. A. F. E. in 1905. According to the last report made by Mr. F. M. Griswold, chairman of the Standard Thread Committee of the National Fire Protection Association, only 683 places have adopted this standard thread, owing principally to the cost and inconvenience of making a change from that already in service. Some cities, however, realizing how important the improvement was, had all couplings and connections made to conform with the standard threads. As there are probably five thousand places that could be equipped with the universal thread, it will be seen that the progress made so far has been slow since 1905, and that unless more interest be taken in the movement it may be a great many years before its universality is accomplished. The work of bringing this important matter to a satisfactory conclusion remains with the fire engineers themselves. They are the most interested in its success as they realize how necessary it is to have couplings of a standard thread ready in case they be called upon to assist or have occasion to seek outside help to stop serious conflagrations. One of the surest means to bring about the speedy standardization of hose couplings is to have the matter introduced at the annual conventions of the I. A. F. E., showing the progress made from year to year and an effort made to smooth out the troubles of those who have been unable from one cause or another to adopt the improvement. Perhaps the appointment of a Standard Coupling Committee to look after and report progress at the meetings would be one practical way to advance the cause and bring about speedier and more encouraging results.
