collected ing chamber 32 by way of conduit 38 leading from check valve 37. When plunger 23 moves inwardly the oil is forced up through check valve 39 arranged directly over chamber 32 at its inner end, across through a groove 40 formed in cap 41 secured to casing 42 of the pump, down through conduit 43 and out through pipe 44 which leads to a collecting sump (not shown). Bolts 45 serve to secure cap 41 to casing 42.

A pipe 46 is connected to pipe a part of the oil coming from an aperture 47 in eccentric 13. When a bore 48 formed in eccentric ring 14 registers, during the course of rotation of eccentric 13, with aperture 47, the oil will spurt through bore 48 and come out a little above the pump and a little towards eccentric 13, so that the rollers 27 will be in the path of the oil as it is thrown outwardly by centrifugal forces. The arrangement is such that the rollers 27 will be lubricated from bore 48 at the time they come in contact with cam 31. i

It is to be understood that various modifications and changes may be made in the em bodiment herein described without departing from the scope of my invention as set forth in the appended claims.

Having thus described my invention,

What I claim is V 1. In a drivingmechanism, the combination of a rotatable eccentric, an eccentric ring therefor, an annular lip extending outwardly and upwardly from said eccentric and forming an annular trough adapted to collect oil flowing from the bearing surfaces of said eccentric and ring, and an oil pump arranged wholly within said trough at the point furthest removed from the center of rotation of said eccentric, whereby said pump may be substantially submerged in the oil at said point in said trough.

2. In a driving mechanism, the combination of a rotatable eccentric, an eccentric ring therefor, an annular lip extending outwardly and upwardly from said eccentric and forming an annular trough, an oil collecting reservoir in said trough located at the point furthest removed from the center of rotation of said eccentric, a cam on said eccentric ring, a pump in said reservoir comprising a plunger having a slotted crosshead, a rock lever adapted to be rocked by said cam, and an arm rigidly connected to said lever and cooperating with the slotted crosshead of said plunger.

3. In a drivin mechanism, the combination of a rotata le eccentric, an eccentric ring therefor, an annular lip extendingoutwardly and upwardly from said eccentric and forming an annular trough adapted to collect oil flowing from the bearing surfaces 44 and leads pump 10 to of said eccentric and ring, and a reciprocat- 1ng pump so arranged within said trough at the center of rotation of the point furthest removed from the center of rotation of said eccentric that the axis of its plunger is tangent to the circular course which it travels with said eccentric.

4. In a driving mechanism, an eccentric, an eccentric ring therefor, a trough on said eccentric surrounding said ring and adapted to catch oil flowing from the bearing surfaces of said eccentric and ring, an oil pump fixed in saidtrough at the point furthest remove( from the center of rotation of said eccentric, a cam on said ring, actuating means for said pump engaging said cam, and an oil conduit leadingfrom said-pump through said eccentric and ring to said cam, the continuity of said conduit being controlled by the relative movement of said eccentric and ring.

5. In a lubricating mechanism a narrow chamber, means for passing oil into said chamber, a pump within said chamber, said pump comprising a base, a cylinder arranged on said base a plunger adapted to be reciprocated in said cylinder and having a crosshead, two supports arranged on said base and at opposite sides of said crosshead, a rock lever mounted on and between said supports and adapted to be rocked around an axis at right angles to the axis of said plunger, an arm rigidly connected to said rock lever at one end and cooperating at its other end with the said crosshead. p

6. In a driving mechanism, an inner rotatable ring,a bearing surface thereon, an outer non-rotatable ring on said bearing surface, a trough surrounding said bearing surface to catch oil flowing from said bearing surface, a pump in said trough, a conduit attached to said pump, said pump removing the oil from said trough through said conduit.

The foregoing specification signed at Oil City, Pennsylvania, this 7th day of November, 1928.

JOHN REID.
