Abstract

1,170,829. Rolling threads; blanks transferring. HARTFORD SPECIAL MACHINERY CO. 6 Oct., 1967 [7 Dec., 1966], No. 45803/67. Headings B3B and B3M. A mechanism for feeding blanks from a feed shoot to a working station, which comprises, for example, a pair of thread-rolling dies 18, 20, includes a reciprocating starter blade 26 which is carried by parallel arms 94 and 96 pivoted at 52 and 92 and which is provided with a lostmotion connection with a driving crank 50 to prevent feeding movement of the blade in the event of jamming of a blank. Reciprocating movement of the blade is controlled by a pivoted crank 50 (Fig. 3, not shown), which is moved anticlockwise by an adjustable spring system 36 and which is moved clockwise by a pneumatic cylinder, or cam follower mechanism 35. Clockwise movement of the crank retracts the arm 94 and hence the blade 26 due to the abutment of faces 134 and 136 on the crank and arm 94. Upon anticlockwise movement of the crank the arm 94 is normally held in contact with the crank by the spring system 110. An extension 100 of arm 96 is biased by an adjustable spring system 110 to urge the blade 26 to the right. But in the event of the blade 26 jamming, the crank continues its movement, Fig. 5, while the arm 94 remains at least partly retracted. The relatively light biasing force of the spring system 110 ensures that the blade 26 is stopped readily, if jamming occurs, without causing undue damage to either the dies 18, 20 or the blanks. The feeding mechanism is suitable also for pointing, slotting, or head-trimming operations.
