Crank 1 rotates about fixed axis A and is connected by turning pair C to slider 6 which moves along slot f of link 2. Slotted link 2 oscillates about fixed axis B and is connected by turning pair D to slider 7 which moves along guide h of slider 8. Slider 8 reciprocates along fixed table 9. Link 3 is connected by turning pair K to slider 8 and is loaded by spring 5. When crank 1 rotates, slotted link 2 transmits reciprocation to slider 8 and link 3. When link 3 is in its extreme left-hand position, one workpiece b drops out of chute a into groove c of pawl 4. When link 3 moves to the right, dog d, mounted on link 3, runs onto lug e of pawl 4, pushing it downward. This releases workpiece b which is then held against the datum surface by link 3 actuated by spring 5.
