this specification.
This'invention relates to improvements in lubricating systemsifor engines and more particularly to engines of the internal com bustion type.
It is one of the objects of the present 1nvention to provide a lubricatmg system which is adapted to oil the cranked shaft of the engine continuously while the engine is in operation.
A further object. of the invention is to provide a lubricating systemin which the same oil may be used over and over a ain.
A further object of the inventio is to provide alubricating system in'which the 'oilflowing from the bearing is screened and cleaned from foreign matter before it is again'fed to the bearings.
.A further object of the invention is to provide a lubricatingsti'uction which "is strong and durable and is well adapted for the purpose .described.
'With the aboveand other objects in view,
-the invention consists of the improved lubricating system and its parts and combinations as set forth in the claims, and vall equivalents thereof.
In 1 the accompanying drawings in which thesame reference characters indicate the same parts in all of the views: Figure l is a vertical sectional fragmentary view of an opposed horizhntal internal combustion enine provided with the improved lubricating system; Fig. 2i's a similar viewv in horizontal section; and Fi the lower portion oft e crank case and the oil pump.
Referring to the drawings the numeral-8 indicates the opposed cylind'e'rs, 9 the crank case, 10 the cranked shaft, 11 the cam; shaft,
12: the pistons and 13 the connecting rods between the pistonswand the cranked shaft. The connecting rods are of tubular form and their bores 1 L (only onebeingshown) extend to points adj aeen t; ;.to the piston pins 15 and the cranked shaftand are in communication therewith by-oil holes 16. Elongated inlet charging openingsl? for the connect:

In use the rotatlon of thegear pump will draw up .the oil fromuthe crankcase and force it on th connecting rod are oscillated up and down, the oil within the said-rods will alternately flow to theopposite ends of the rods and lubricate the bearthe oil'holes of the rods.
ings therepf through The surplus oil flowing from or discharged from the bearings will drop to the bottom portion of thecrank case and pass through the again be drawn into the pum same course as before descrlbed while/the engine is in operation.
.From the foregoing seen that the lubricating system is ofvery screen and the screened oil will,
