15.  Q. Is the Baker gear a direct or an indirect motion?

A. It is direct, going ahead for an inside admission and indirect backing up, and just the opposite for the outside admission type.

16.  Q. What parts of the Baker gear take the place of the link which is used by the Stephenson or Walschaert motion?

A. The radius bars and reverse yoke.

17.  Q. What relation to the main pin is the eccentric crank set to?

A. The eccentric crank always follows the main pin.

18.  Q. Should the eccentric rod or eccentric crank break how is the engine put in condition to proceed?

A. The disabled side can have lap and lead travel and a port opening equal to the lead for all cut-offs.  First block the bell crank by using a “U” bolt (which should be provided) in the holes placed in the gear frame for this purpose.  Throwing reverse lever in mid-gear will help to get bell crank in position to block.  Second, take down broken parts.  Third, knock out back pin of short reach rod and throw reverse yoke in forward motion against gear frame.

19.  Q. What is to be done should a gear connection rod break?

A. Do the same as for a broken eccentric or crank.

20.  Q. What is to be done should the upper part of gear connection rod break?

A. If break is close to the middle pin, do the same as for a broken eccentric rod and also tie lower end of gear connection rod to keep it from swinging.  If break is near the top and below the jaw, first block the bell crank and wire the connection rod fast to radius bars.  If break is through top jaw, do the same as for broken eccentric rod.

21.  Q. What is to be done should a radius bar break?

A. Do the same as for broken eccentric rod.

22.  Q. If the horizontal arm of bell crank should break?

A. Same as broken eccentric rod.

23.  Q. What is to be done should the vertical arm or bell crank break?

A. Take down union link combination lever and valve rod, then block valve over ports by using set-screw in valve stem cross-head provided for that purpose.

24.  Q. Should you break cross-head arm or union link, what would you do?

A. If rod be provided to secure lower end of the combination lever to guide yoke, remove broken parts and proceed with full train, working engine at long cut-off.  Otherwise would remove broken parts, combination lever and valve rod, cover ports, and proceed on one side.

25.  Q. What do you do if a union link should break?

A. Same as for a broken cross-head arm.

26.  Q. What is to be done if a combination lever should break?

A. Tie combination lever plumb, same as for a broken cross-head arm, if it is possible.  If not possible, take down the combination lever and valve rod and cover the ports.

27.  Q. What is to be done if a valve rod breaks?
