that I have concluded that they are among if not actually the best sight feed Lubricator on the market to-day.  The query referred to was:  “Why does my glass fill with oil?” Now the answer to this is so simple and so clearly no fault of the Lubricator that I am entirely satisfied that by recommending either of these Lubricators you will get value received; and here is a good place to answer the above query.  If you have run a threshing engine a season or part of a season you have learned that it is much easier to get a poor grade of oil than a good one, yet your Lubricator will do this at times even with best of oil, and the reason is due to the condition of the feed nozzle at the bottom of the feed glass.  The surface around the needle point in the nozzle becomes coated or rough from sediment from the oil.  This coating allows the drop to adhere to it until it becomes too large to pass up through the glass without striking the sides and the glass becomes blurred and has the appearance of being full of oil, so in a measure to obviate this Powell’s Lubricators are fitted with 3/4 glasses-being of large internal diameter.  The permanent remedy however is to take out the glass and clean the nozzle with waste or a rag, rubbing the points smooth and clean.  The drop will then release itself at a moderate size and pass up through the glass without any danger of striking the sides.  However, if the Lubricator is on crooked it may do this same thing.  The remedy is very simple-straighten it up.  While talking of the various appliances for oiling your engine you will pardon me if I say that I think every traction engine ought to be supplied with an oil pump as you will find it very convenient for a traction engine especially on the road.  For instance, should the engine prime to any great extent your cylinder will require more oil for a few minutes than your sight feed will supply, and here is where, your little pump will help you out.  Either the Detroit or Powell people make as good an article of this kind as you can find anywhere, and can furnish you either the glass or metal body.

Hard Grease and a good Cup come next.  In my trips over various parts of the country I visit a great many engineers and find a great part of them using hard grease and I also find the quality varying all the way from the very best down to the cheapest grade of axle grease.  The Badger Oil I think is the best that can be procured for this purpose, and while I do not know just who makes it, you will probably have but little trouble in finding it, and if you are looking for a first class automatic cup for your wrist pin or crank box get the Wm. Powell Cup from any jobbing supply house.

These people also make a very neat little attachment for their Class “A” Lubricator which is a decided convenience for the engineer, and is called a “Filler.”  It consists of a second reservoir or cup, of about the same capacity of the reservoir of Lubricator, thus doubling the capacity.  It is attached at the filling plug, and is supplied with a fine strainer, which catches all dirt, and grit, allowing only clear oil to enter the lubricator, and by properly manipulating the little shut-off valve the strainer can be removed and cleaned and the cup refilled without disturbing the working of the Lubricator.  This little attachment will soon be in general use.
