| A hydro-static lubricator in the cab supplies the booster and the stoker. |
| By this simple contrivance the capillary action can be stopped or renewed in a second, without removing the top of the lubricator. |
| The lubricator is located in the cab so there is a gradual descent in the oil pipe from the lubricator to the steam chest. |
| The ratchet wheel and pawl shown in fig. 48 are part of the lubricator. |
| If lubricator feeds regularly when working steam and too rapidly after shutting off, what is the trouble? |
| Carefully adjusting the drips from the lubricator, he set them to give a more liberal supply than was usual. |
