The remainder of thespace between two consecutive bearings is occupied by a hollowshaft outside the main shaft. This also rests in bearings andcarries the pulley or gear giving motion to the disconnectibleshaft or machine. It also carries the corresponding half of thefriction-clutch. This hollow shaft is called a quill. Whennot in motion it has no connection with the main shaft andoffers no impediment to its motion. When the clutch is thrownin gear by means of the handle, Figs. 176 and Ijda, the quillrevolves with its attachments. The Penstock.—This term is applied to the pipe whichbrings the water from the canal or other source of supply to theflume. • It is a very unimportant detail of the system when thesource of supply is near the wheel. When, however, as some-times occurs, it takes a length of miles, it becomes of primaryimportance, and phenomena
