The Wireless Telephone as a Fire Chief’s Aid
Chief Moran of Hartford, Conn., Fire Department Receives Messages in His Moving Car from a Residence—Not Perfected in England
A GREAT deal of interest has been aroused by a series of experiments that have been conducted by Chief John C. Moran of the Hartford, Conn., fire department in the use of the wireless telephone outfit, messages having been successfully transmitted from the home of C. G. Tuska in Oakland Terrace in that city to Chief Moran and other offices of the department while driving in the chief’s car. Through the use of a portable wireless telephone outfit rigged up by Mr. Tuska, it has been possible for Chief Moran and the members of his department to receive messages in any part of the city while the car was in motion. The experiments were conducted on Monday and Tuesday, June 13 and 14. Early in the afternoon of Tuesday Superintendent of Fire Alarms E. A. Sullivan, with Driver Philip Duffy, went to Mr. Tuska’s house, where an inspection was made of the room and apparatus used in experiments, the portable outfit having been transferred to the chief’s car, the party proceeding first to the Capitol grounds. J. C. Randall, in charge of sending the messages, first sent the message: “Do you get me.” Mr. Tuska, who was “listening in” heard this message very distinctly, but there was no way of replying as there was no sending apparatus on the car. This message was followed as the party drove from one part of the city to another by reproduction of records played on a victrola and other messages from Mr. Randall. These were heard with no appreciable diminution of the music, despite the fact that the automobile was making rapid progress. Commissioner John J. McIntyre and Commissioner W. J. Rankin were also members of the party, and were very enthusiastic over the possibilities of the apparatus in conjunction with fire fighting. It was thought possible that there might be some difficulty in the east section of the city owing to the fact that several new steel buildings are in process of construction, but this apparently had no effect on the wireless as the voice and music tones were heard equally as clear here as in other parts of the city. It may be that great possibilities are opened for the use of the wireless in fire departments through these experiments that the progressive chief of Hartford is making. Your letter dated 12th April, addressed to the Chief Officer, London Fire Brigade, has been passed by him to us, in order that we may give you a certain amount of information regarding the experiments we carried out in wireless telephony, between the London Fire Brigade headquarters and a mobile fire tender. These tests were carried out some months ago, the wireless telephone sets emplo3’ed being of our standard aircraft type. A very successful demonstration was carried out between the headquarters and the fire tender over a range of ten miles. We understand that the fire brigade were satisfied with these tests.
Not Perfected in England
It will be recalled that FIRE AND WATER ENGINEERING made some inquiries recentty of the chief of the Paris, France, fire department and his reply, which was published in a subsequent issue, seemed to show that the use of wireless telephony in connection with sending fire alarms was not a very great success. FIRE AND WATER ENGINEERING also wrote to the chiefs of the London and Liverpool fire brigades and their replies, which follow, would seem to indicate that thus far the use of wireless has not proved very successful in these cities. It may be that, after all, America will lead in this progressive step, as it has in so many other matters of fire-fighting

To the Editor:
Replying to your letter of the 12th instant, it is contrary to the regulations of the council for me to express opinion for publication on any matters experimented with by the London Fire Brigade. The experiments carried out with wireless telephony were undertaken for us by the Marconi’s Wireless Telegraph Co., Ltd., Marconi House, Strand, London, to whom I have forwarded your letter. Doubtless they will be pleased to give you all the information that you desire. Yours faithfully,
A. R. DYER, Chief Officer,
London Fire Brigade.

To the Editor:
In reply to your letter of April 12, re the above, experiments were made in August last year. A receiving and transmitting set were installed in the Central Fire Station, and a similar set carried on an -engine which went to Britannia Street, a short cul-desac off Atlas Street, a distance of 1600 yds., both streets consisting of cotton warehouses, there also being a large bottling store and a mill. There was much iron about, but a message was received from the engine when there, with 18-inch copper wire aerial 32 feet long, 10 feet above the ground and supported by an ordinary ladder. Part of the message got jammed through other wireless working at the same time.
A second experiment was made from a field on the outskirts, about four miles away. The message sent from there did not reach the Central Station.
As a result of the experiments it was decided that the wireless telegraph is not at present suitable for fire brigade work, due to its unreliability, delicacy of construction, maintenance, liability to vibration, etc. The recent successful wireless tests in London were with telephony. These machines are very delicate. An exhibition was given at the university in this city; it was successful. The machines were the property of the Marconi Company, the distance was 13 1/2 miles, but the machines are very expensive and open to exactly the same disadvantage as the telegraph machine, but to a larger degree.
The chief officer of the London Fire Brigade, in answer to my inquiry, wrote that, in his opinion, the wireless machines were not yet suitable for fire brigade work, except, perhaps, between fireboats and the shore.
Any further information you may desire, if in my power, I shall he only too pleased to furnish you with. Meanwhile, I remain Yours very truly,

The firemen of Katontown. N. J., have presented the township committee with a check for $775 to be used to meet the cost of installing a Denver quadruplex siren. Several weeks ago the company at their own expense laid hardwood floors in the room donated for their use and purchased furniture amounting to over $500 for their club room.
