Among the recent improvements that have been made by Dr. Sargent in gymnasium apparatus is a new arrangement of pulley-weights, which tends to reduce the friction to a minimum, and thereby renders work on them easier and more agreeable. This result is accomplished by substituting rolled shafting, similar to that used in mills, in place of the plain iron rods now in use in the old machines; by changing the bearings so that the weight box will run exactly parallel to the bars, and thus prevent lateral pressure, and by increasing the diameter of the pivot...
...notice a very marked improvement, and one that will, in time, cause the old machines to be supplanted by the new ones. For, as Dr. Sargent says, a man does not so much mind the weights in the box, but he instinctively turns to the machine with the less friction...
...Sargent has also introduced a system of swivel pulleys in the higher weights, so that side movements can be performed without involving any lateral friction. To the sliding chains and other machines of a similar nature, the perpendicular rods which support the pulleys have been directly attached, instead of being fastened to the wall or floor as has heretofore been the case. In this way each machine is entirely independent of stationary fastenings, and, when necessary, may be easily transported. Three horizontal bars, parallel to each other, have been placed in the gymnasium. By this means a greater variety...
...students have attempted to settle for themselves have been amicably arranged, and no lasting ill feeling has resulted. Could a committee composed of members from various faculties do better? We think not. No committee containing human elements can be infallible, and we believe that instead of lessening the friction between athletic rivals, the committee proposed above will only change its direction...
...examinations for this half-year are nearly completed, and they have passed off as a whole with but little friction and unnecessary inconvenience. The college at large is to be congratulated on the results. But pleasant as it may be for those who have completed, or almost completed, this trying undertaking, a hard task remains for quite a number of men. It seems hard that the examinations in two such courses as History XII. and History XIII. should come on these two successive days at the end of the examination period. These two courses cover contemporary periods in the history...
