M 1 •\ ON THE SCROLL DRUM. 85 ON THE SCROLL DRUM. By GEORGE FOWLER. In a late discussion on Mr. Daglishs paper upon the Counterbalancingof Winding- Engines, reference was made to a series of experimentsconducted by the writer upon the actual expenditure of power in largewinding* engines. These experiments formed the subject of a paperpublished in the Transactions of the Institution of Mechanical Engineers. It was shown by these experiments that the uniformity of load to beobtained by a system of counterbalancing, or by the scroll drum, wasmerely one element in the question of winding economy, and that themass of machinery in motion introduced dynamical considerations ofeven greater importance; that, in fact, it was as necessary to compensatefor dynamical forces as for statical ones. Since the date of those experiments, considerable alterations havebeen made in the working loads upon the scroll drum there referred to,and it may probably be interesting to compare the results of the ol
