Thanks again. #14 I think is the spring that locks the latch that closes the barrel & cylinder to the frame. The spring I'm referring to raises the "pawl" (Thanks Tom) which engages the cylinder when the hammer is pulled to the rear. It raises the pawl and locks the cylinder with the chamber in alignment with the barrel.

Here is a description I found:

As the Pawl Spring tensions up against the Lifter, the Pawl moves forward and engages the cylinder ratchet. The Lifter also causes the Hammer to rotate rearward, causing the Hammer Strut to begin compression of the Mainspring. Pressure on the Sear Spring causes the Sear to rise and engage the SA notch on the Hammer. Continual pressure on the Trigger causes the Lifter to rotate the Hammer such that the Hammer disengages the Sear. By this time, the Pawl would have fully rotated the Cylinder and the "cylinder notch" integral to the Trigger should proceed from the frame and engage and secure the Cylinder. The Hammer drops and the gun discharges.

Release of the Trigger allows the "cylinder notch" to drop free of the Cylinder. The Trigger Spring pushes the Trigger back towards its position of rest, allowing the Pawl to withdrawl from the Cylinder Ratchet and the Lifter to reengage the Hammer. Pressure from the lower leg of the Mainspring pushes on the Hammer, causing it to "rebound" away from the spent cartridge.
