| B A clutch control enables each or both of the carriages to be mechanically moved in either direction and stops are provided which can be set to automatically check the feed of the carriages at the proper point. A hand-wheel provides for rapid manual traverse of each table in either direction. The spindles are operated through a clutch, each controlled by one of the two treadles located at the base of the center leg of the machine. By depressing either one or both of these treadles, the rotation of either one or both of the spindles may be stopped. In operation, the work, which is already drilled, is mounted on the carriage, supported and held by the two rests. The reamer shank is passed through the drilled hole in the work and is fastened in the spindle chuck, allowing the cutting portion of the reamer to extend beyond the work. Then, with the reamer rotating, the carriage feed is engaged, moving the work away from the head, of the reaming machine and causing the reamer to be drawn through the barrel. A gear pump, mounted on a special base located back of the head of the reaming machine, is driven by means of a vee belt from an auxiliary pulley on the main drive shaft. Oil is pumped through the hollow shank of the reaming tool and escapes through small holes in the reamer itself, assuring delivery of an adequate supply of lubricant to the work. The oil then passes out through the ends of the barrel, carrying chips with it, is strained, and flows back into the reservoir located beneath the bed. | ||
