September, 1905 '7 good type, with a large oil reservoir in the hub, and, as it ran 1,500 a minute, it will be seen, in this case, too, that extreme care was needed to insure a good fit and a good support for the frame. This was put in, and no trouble was experienced with this pulley for nearly a year, when, one day, without warning of any kind, the shaft was forced to one side from its clamps, and the pulley came to the floor with a crash, striking the spot from which the writer had just moved while making some adjustment to the tilt of the upper wheel. The pulley was demolished, and the belt got rubbed a little, but in half an hour we were running again with another old pulley in place. This old pulley was a plain, cast iron hub, and, as I foresaw some trouble for the proper means of oiling, I had a groove cut in the shaft half its length and a half-inch deep, into which oil was dropped from a cup at one side, the capillary attraction keeping the pulley well oiled as long as the cup was not neglected. There is one poor feature about this resaw rig that should have been avoided, and that is, the machine must run all the time the mill is running, or the belt must be taken off. As the sawing was rather intermittent, this did not work any hardship, but if it had been in regular use, a friction clutch pulley would have been the logical remedy. This machine was intended to be driven from under the floor, and that would have been the proper position for the drive shaft, but the owners of the mill were set against any proposition of that kind at the starting of the mill, though an after ex- perience showed that it would have been, by all means, the cheapest in the end. The little saving on the lower framing does not compen- sate for the costly frame and the longer belts and increased cost of maintenance of the over- head shaft. This method o
