IPC: B23Q7/03
Abstract: 171,905. Thompson, J. T. Nov. 30, 1920. Milling-machines. - Metal-working machines, particularly such as are adapted for the quantity production of small articles, are provided with a feeding belt device which may either be traversed or held stationary during the cutting operation, and which comprises adjustable automatic means for gripping and positioning the blanks and for releasing the finished articles. The table 8, Fig. 1, may be traversed by a screw 7 on guides supported on a bracket on a vertical slide 3 operated by a hand-wheel 4. The spindle 40, driven by reduction gearing from an electric motor 44, carries a bevel-pinion driving through an inclined shaft 49 and gearing, a pinion 31, Fig. 3, on a shaft carrying an elliptical pinion 35 and an intermittent pinion 36 engaging respectively with an elliptical pinion 37 and a pinion 38 loose on a shaft 24. The blank-carrying feed-belt 25, supported by the table 8, runs over sprockets 12, 11, the latter being connected by spur and bevel gearing to the shaft 24. By means of a clutch member 39 operated from a pedal 59, the shaft 24 may be locked to either of the pinions 37, 38 to impart either an intermittent or a variable speed to the feed-belt according to the nature of the work to be performed. In an intermediate position of the clutch member the feed-belt remains stationary, and the initial setting may be performed by means of a hand-wheel 80. The work-pieces are carried on chucks 60, the jaws of which comprise members attached to adjacent links of the belt, one jaw being adjustable as shown in Fig. 5. The jaws are thus automatically opened as the belt passes over the sprockets, the blanks being inserted in the chucks near the sprockets 12 and automatically discharged while the belt passes over the sprocket 11. The feedbelt is held firmly to the table to prevent chattering during the cutting operation by adjustable guides 74, which may also engage the work. A spring-controlled rack-bar 81 connected to the clutch-operating mechanism carries a finger 84 so positioned that any blank that is not correctly chucked slides the rack-bar to shift the clutch to its neutral position and so stop the feed-belt.
