In a gravity feeder, the escapement allows parts to be fed one at a time.

• A. Escapement
• B. Screw guide
• C. Clamping cylinder
• D. Torque tool

Answer: (A)

In a gravity feeder, the device that controls the release so parts come out one at a time is the escapement. It acts like a timed gate that holds back the next part until the previous one has moved forward enough, then lets the next part drop or slide through. This prevents multiple parts from spilling at once and keeps the feed consistent, which is essential for reliable downstream handling or assembly. The other options don’t fit this role. A screw guide helps keep parts aligned on their path but doesn’t regulate the timing or the single-item release. A clamping cylinder holds parts in place during processing but doesn’t manage sequential release from the hopper. A torque tool applies fastening torque and isn’t part of the feeding mechanism at all.
