Pre-lube device

A device for lubricating an internal combustion engine upon ignition and prior to the start thereof, comprising:

• chamber means for storing a quantity of oil of sufficient amount to prelubricate said engine, said chamber means being adapted for fluid communication with said engine,
• pump means in fluid communication with an oil pan of the engine and with said chamber means for the supplying oil under pressure to said chamber,
• rigid moveable piston means disposed within said chamber for evacuating oil from the chamber to said engine, said piston means having an elongated rod associated therewith;
• said piston rod having a head mounted to an end surface thereof,
• power chamber means disposed adjacent to said oil chamber means, said power chamber means including power spring means, at least one surface of which abuts said piston means for moving the piston means under pressure within said oil chamber means in order to evacuate oil therefrom, and
• locking means for releaseably receiving said piston rod head, comprising moveable roller means adapted to receive and secure said head said roller means comprising multiple rollers adapted to move radially outwardly from the diameter of said piston rod and adapted to secure said head around the circumference thereof, in order to secure said piston means associated therewith against movement such that when said ignition is actuated it causes movement of said roller means thereby releasing said head and said power spring means, whereby said piston means is moved under pressure in such a manner as to evacuate the oil from said chamber into and throughout said engine in order to lubricate the engine prior to start.
