The meeting was called to order at 2.30 p.m. The President read his annual address. The President.-There is now an opportunity for any business if any is to be presented this afternoon. If not we will proceed to the reading of papers. Is Professor Robinson's paper ready? Professor Robinson.-I have brought in two small items at this meeting for the consideration of the Society, and I hope not to take much of the time of the Society with them. One is in regard to the back pressure on valves. The other is a supplement to the paper I read at the Philadelphia meeting on "Pumping Engines." The matter I have to present on the subject of valves was experimentally obtained by a student in the mechanical laboratory of the Ohio State University about a year and a half ago. The question is often raised, I presume, by members of the Society in practice what pressure to allow for a slide valve in determining the resistance of that slide valve. We are at first, perhaps, inclined to take the whole area of the slide valve, multiply that by the pressure in the steam-chest, and call that the pressure of the valve in its seat. I directed these experiments for the purpose of throwing some light on the question. Professor Robinson then proceeded to explain his drawings. The President.-While we are waiting for the next paper, I have an explanation which I wish to make at the request of Colonel Laidley. Colonel Laidley is the officer of the army to whom we are indebted, I presume, for the bringing up of the form of testing machine finally adopted by the United States Board and built and put down at Watertown. In debate, I think at the last meeting, it was stated that the contract made for that board had been annulled before the board itself had taken action. He says that this was an error; that it became necessary that the board should either have the machine. that had been contracted for or lose the money appropriated for it, or annul the contract. The board chose the latter alternative. "Had it not done so, the contract would not have been annulled,” he continues," and I should have had at this moment the machine." He goes on to express his regret at that action. He desired a correction of the statement to be made. A paper by Mr. Hill on the "Difficulties of Road Locomotion, their Cause and Cure," was read by the Secretary. Mr. Oberlin Smith read a paper on the Systematic Preservation of Drawings." The meeting then adjourned till the following day at 7.30 P.M. In the evening was held the subscription dinner, attended by a large delegation of the membership. It was held in a room adjoining the headquarters, and several ladies were present. It was a very pleasant reunion. |
