Compression grease cups are used extensively on engines for lubricating the crank-pin and wrist-pin, also pillow block bearings for crank shaft; in fact this method of lubrication for all kinds of bearings and journals is becoming universally adopted.
In construction the Besly Bonanza Cup is simple and durable. The outer casing is threaded and fits tightly over the bottom part of cup. After the cup has been put in place, remove the top part, fill it with Helmet oil or grease and screw it on the lower part for two or three threads. The cup is then in working order.
To insure a plentiful supply of grease to the journal or bearing, all that is necessary is to give the top part of cup an occasional turn.
C. H. Besly & Co.’s Helmet Solid Oil is for use in compression cups, and is a perfect lubricant, in fact it is said to be the best.
MINNEAPOLIS TRACTION ENGINE.
The engine is supplied with a return flue, straw, wood and coal burning boiler. The shell of the main flue is cylindrical in shape, but tapers toward the front end. By this arrangement the return flues can be set lower at the front end, which it is claimed has some advantage in protecting front end of flues when ascending steep hills.
The steam used is superheated by being conducted through a pipe which extends from the top of the dome on the inside of boiler through the front head and smoke stack to the steam chest.
The engine is of the Side Crank, Side Gear style, the frame of which is the girder pattern with bored guides, and has an overhanging cylinder attached to one end, and contains the pillow block bearing at the other.
It is fitted with the Woolf Valve Gear for reversing, [Friction Clutch], [Cross-head Pump], [Injector], Syphon for filling water tank on front end, and a large Foot Board with Tool Boxes attached. The wheels are of steel, and the traction or drive wheels are furnished with malleable mud cleats extending diagonally across the entire width of tire.
