Abstract
1472862 Bar-stock feeding WICKMAN MACHINE TOOL SALES Ltd 30 April 1974 [15 March 1973] 12544/73 Heading B3B A bar feed control device mounted on a multispindle lathe comprises an arm 15 fixed to a shaft 14 which can be rotated to angularly swing the arm 15 and moved axially to laterally move the arm, the arm including a stop surface 17 and a projecting finger 16. In a method of controlling the bar feed, the shaft 14 is moved axially to move the arm 15 away from a spindle 12 and also rotated to swing the arm 15 into alignment with the said spindle so that a bar fed through the spindle chuck to engage the stop surface 17 protrudes more than is required. The arm is moved further angularly so that finger 16 knocks the bar so that if only a short section of the bar is remaining it will be knocked from the spindle chuck. If a long section of bar is remaining a lost motion drive in the rotation of the shaft 14 allows the arm 15 to bear against the bar. The shaft 14 is then retracted axially to move the bar back into the spindle chuck to a required machining position, and then rotated to swing the arm to a clear position.
