Workorsnkshoft 14L, tho lattes: sing hollow for: iogout of cossooting-rod bearings midi splashing on to the cylinder walls and hence under such circumstances these walls are not properly lubricated.
It is to overcome this objection that the thermostatically-controlled ports have been proy ided, and, accordingly, when the engine and the lubricant are cold, the ports 23 and 24 are open and the oil is pumped or played out through them directly on to the cylinder walls, the wrist-pin bushings under such circumstances creating enough back pressure on the oil to effect its delivery through the connecting-rod openings in the manner stated.
Just as soon as the motor warms up. for instance to a tcn'iperature of sixty degrees Fahrenheit, the oil will pass by the bearings and on to the cylinder walls.
To prevent over oiling under such conditions, the thermostat, by expanding, turns the sleeve 22 and closes the holes through the sides of the connecting-rod thus cutting ofi' this extra supply of oil which is not then needed.
In other words, surplus or extra oil is played or fed on to the cylinder walls while they are cold and before th normal lubricating system has become cflicicnt after which the supply of auxiliary oil is automatically terminated.
An appliance of this kind is particularly advantageous to temporarily or preliminarily supplement the action of the force-feed lubrication system and it overcomes one of the recognized serious disadvantages of the latter.
The new structure having once been installed in a motor, its action is entirely automatic and it requires no attention on the part of the operator who is assured that the engine is receiving adequate, but not undue lubrication under all conditions.
The advantages accruing from the employment of a construction of this character are more or less manifest and those skilled in this art will readily understand that many minor mechanical changes may be made in the one embodiment of the invention presented and still be within the purview of the invention as defined by the appendcd'claims and withoutthe loss of any of its material benefits and advantages.
\Ve claim:
1. In an internal-cornbustiou engine, the combination of the engine-cylinder, the reciprocatory piston therein, the crank-shaft, the connecting-rod associated with said piston and crank-shaft and having a passage therein with means for delivering the contents of said passage on to the cylinder wall, means to supply lubricant to said connecting-rod passage, and automatic means gov erning the discharge of said lubricant through said delivery means.
2. In an internal-combustion engine, the combination of the engine-cylinder, the reciprocatory piston therein, means to lubricate said cylinder and )isto1i, tl1e crankshaft, the connccting-rod associated with said piston and crank-shaft and having a passage therein with means for delivering the contents of said passage on to the cylinder wall, means to supply lubricant to said connecting-rod passage, and thermostatic means automatically governing the discharge of such lubricant through said delivery means.
3. In an llllGl'llill-COl'IllHlStlOn engine, the combination of the engine-cylinder, the reciprocatory piston therein, means to lubricate said cylinder and piston, the cranbshaft, the connecting-rod associated with said piston and crank-shaft, said connectingrod having a lengthwise passage therein with a lateral discharge port to direct the delivery of the contents of such passage on to the engine cylinder, a spiral thermostat in said passage controlling said connectingrod discharge port, and means to supply lubricant to said connecting-rod passage.
In witness whereof wehavc hereunto set our hands and seals.
