Thepump is driven by the crankpin mechanism (H and G in theengraving) and the piston rod E. A lever (J) is driven by thefittings attached to it, and the ratchet wheel D is advanced bya certain number of notches, as determined by the stroke,which depends upon the position of the fitting K. The lubri-cator is mounted upon a stand and placed in a convenient loca-. LUNKENHEIMER ilECHANlCAI. OH. CUP.

Acheck valve is placed in the oil connection to secure satisfac-tory working of the device. In starting the engine, if moreoil is desired, the ratchet-wheel may be turned by band. Theratchet-wheel and pawls are of hardened tool steel, all othermetal parts being of hard bronze composition.
