Davenport Milling Machine
The illustration shows a new hand- and power-feed milling machine that has been placed on the market by the Davenport Manufacturing Co., Meadville, Penn. It is known as the company's No. 2 machine. The feed of the table is obtained either through the hand lever, which gives rapid movement or through a handwheel, which gives a slower and more sensitive feed. The hand lever may be used in any position, or disengaged entirely, by means of a spring plunger. One full movement of the hand lever moves the table about 5 in. Power feed is available in either direction, and is obtained through a chain-driven feed box, giving six changes. This is assembled as a unit and placed in the column. All parts of this mechanism are oiled from one large pocket, which is filled through an opening in the column. The table is provided with T-slots and has oil grooves on the sides and pockets at the ends. The spindle is of forged crucible steel, is hollow and runs in bronze boxes, which are adjustable for wear. Large reservoirs with glass indicators to show the oil level are provided. The countershaft gives two speeds and is equipped with clutch pulleys and self-oiling bearings. Equipment includes arbor, draw-in rod, oil pot, wrenches and overhead works. If desired a lubricant, pump piping, etc., can be furnished as an extra. All machines have a reservoir cast integral with the bed. |
