AUTOMATIC OILER.
An Automatic Oiler is used on an engine to keep the cylinder, piston and valve lubricated, and is most essential for the safety and easy operation of these parts. It works automatically and is supplied with a glass tube through which the oil can be seen passing into the cylinder. The feed can be regulated to allow just the required amount of oil to pass into the cylinder.
Where a sight-feed automatic oiler is used on an engine there can be no excuse whatever for the engineer to allow the cylinder to run dry and cut, as he at all times can see whether oil is passing into it or not.
Q. How do you fill an automatic oiler?
A. Close valves D and E, open valve G to draw off the water. Close valve G and take out filling plug C, fill A with oil and replace plug C, then open valve D, and the flow of oil to the cylinder can be regulated with valve E.
Q. Will the oil feed as soon as the oiler is filled?
A. No; time must be given for sight-feed glass and condensing chamber to fill with water of condensation.

Q. How is a double connection automatic oiler attached?
A. First, the steam pipe must be drilled and tapped above the throttle with ½ or ¾ inch gas tap, as may be necessary to receive the oil discharge pipe of oiler and put oiler in place. Then tap the steam pipe about 18 inches if possible above the top of the condensing chamber and fit in a ¼ inch gas pipe for steam connecting tube, which attaches to the top of condensing chamber. ([See illustration.])

Where the steam pipe cannot be tapped 18 inches above the condensing chamber, it may be tapped lower down and the steam connecting tube of required length be bent in a horizontal coil. With the single connection oiler it is only necessary to drill and tap one hole in the steam pipe.

Q. Should oiler become clogged, how can it be cleaned?
A. Open the valves, by which steam can be forced through it, and all the passages will be cleaned. This can be done without stopping the engine.
Q. If oiler is not in use and in danger of freezing, what should be done?
A. Leave valves D, G and E open, and all water will be drained off.
Q. If the glass tube in oiler should get broken, what should be done?
A. Shut valves D and E, remove broken glass and replace with new.
Q. How can oil be prevented from sticking to lubricator glasses?
A. A very simple remedy is to fill the glass with glycerine and let the oil feed through it.
