Application filed April- 7, 1911. Serial No. 619,524. I
To all whom it may concern: Be it known that I, ANDREW C. DANVER, a cit-izen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements 1n Automatic Oili'ng Devices for Push-Rods of Automobile-Engines, of which the follow-' ing is a specification. My invention relates to improvements in automatic oiling devices for push rods for automobile engines, and the purpose of my invention is to provide a method by which the reciprocating movement of the push rod will operate an oiling device so that the push rod will be constantlyand thoroughly lubricated so long as any oil remains in the crank case of the engine. I- accomplish this object'by the -mechanism disclosed in the1accompanying drawings in which F'gure 1 "shows a vertical section through the push rod with its inclosing guide and showing also a portion of the valve stem OP. erated by the pushro'd. FigrQ, a cross section through g the line wa; of Fig. 1, and Fig. 3, a vertical section with the push rod at that point of its movement farthest removed from the position shown in Fig. 1.
The various parts of the mechanism are designated by the same letters throughout the several views.
In Fig. 1, a, a, a and a represent in cross section the different parts of the inclosing guide or jacket of the push rod; a being the outer portion ;0f the guideta the flange by which the guide is secured to the engine-case; a a projecting lower end of the guide fitting into a suitable hole in the engine case; 'anda the vertical wall of the guide recessed by the annular; recess 7), as hereinafter described.
al is the push'rod, bored out so as'to form the chamber Z.
k. is the cam and h the roller by which the" push rod is operated, the roller being secured to the push rod by the pin or, stud .ir
The wall of the push rod is cut away in the line of the plane of the roller, as shown at l in Figs. 1 and 3, thus leaving additional space for the entry of the oil as it is splashed by' the movement of the cranks.
e is' a bolt or set screw threaded into the push rod as shown and having the check nut e thereon.
g is the valve stem and e the head of the fiber cushion f against which the lower end of the valve rod strikes.
About the middle of the thickness of the cylindrical wall H3 of the push rod guide is an annular recess represented by the letter '6; This recess extends all the way around the push rod guide and is of such a depth as may be necessary for the purpose for whichit is intended-the depth shown in the drawing being about the proportional average depth desired. This annular recess b divides the upper portion of the push rod guide intotwo concentric cylinders, as shown best'in Fig. 2 by the letters aa Toward the bottom of the annular recess are cut the holes m'm through the inner wall a of the' push rod guide. These holes may 'beas many in number as may be found best adapted to accomplish the purpose desired. There are also anumber of holes in the wall of the push rod (i as shown at m, equal in number to those in the push rod guide a, and adapted to come into opposition' with the holes m -m at certain points in the travel of the push rod both upward and downward.
lVithin'the annular recess 6 is coiled a spiral spring 0 extending from the bottom of the recess practically to the upper end of the push rod guide when uncompressed.
Secured to the top of the push rod by the check nut e is the member (Z which moves with the-movement of the pushrod itself. The member d has two projecting flanges d-d the outer one operating principally as a dust cap but the inner one, d performguide so as to form a piston therein, thus converting the chamber 6 in the push rod guide in conjunction with the projection d into a pump operating with the operation of' the push rod itself.
it is a slight depression extending circumferentially around the push rod and serving to retain a slight body of oil to aid in the lubrication of the push rod.
The relative size of the various'parts is such that the push rod d fits the casing a in such a manner as not to rattle, but still so as to leave an oil space between the two, this oil space being indicated by s.
The operation of my device is substantially as follows :The splashing of the oil by the cranks of the engine keeps the cam,
the roller, the space 8' i and the interior of the lower cavity of the push rod constantly covered with a film of oil. As the push rod cess Z) and this continues until the push rod reaches its highest point, as shown in 1. As the push rod descends it pushes a portion of the oil back through the same holes into the cha ber- Z until the holes m cease to be in opposition .to the holes 'm'- m/, when the pressure in the annular recess 1) then forces the oil through the holes m-m' into the oil space between the push rod and the inner wall of the push rod guide a thus keeping the push rod thoroughly and completely lubricated so long as any oil remains in the crank case; As will be seen in Fig. 3, this pressure upon the oil takes place during the time required by the push rod to pass from the point where the holes m cease to be in opposition to the holes m'm' to the point where the ush rod reaches its lowest position, as shown in said Fig. 3. This alternate lifting and forcing outward of the oil continues as longas the engine is in operation. While much of the oil reaches the chamber I) through the holes m- -m'm' still some oil reaches said chamber from the space s between the push rod and its guide.
- The roller h fits somewhat loosely in the push rod d sc that there is abundance of space around and at the sideof the roller h for oil to get intoand partially fill the chamber Z3 Some oil is also drawn up through the space 8 .by the suction of the piston d before the beginning of opposition of the holes m with m' -m.
The spiral spring 0 helps to maintain contact between the top of the push rod and the valve stem but serves principally to displace the oil in the cavity 6 by the compression of the spring as the push rod descends, thus,
helping to force the oil through the holes m-m into the oilspace s.
lVhile the drawing discloses only the roller operated by ,a cam, it will be easily seen that my device is equally applicable to an engine where the push rod terminates in a flange or mushroom head, the only con dition in connection therewith being that there should be means for the oil to reach the interior chamber of the push rod.
Having now described my in vcntion, what I claim and desire ent is 1. An automatic oiling device for p'ush to obtain by Letters Pat-' rods for automobile engines comprismg a push rod; a push rod guide having a pump chamber therein and a piston fitting said chamber and connected with and operated by the push rod, substantially as set forth for the purpose specified.
2. An automatic oiling device for push rods of automobile engines consisting of a hollow push rod; a push rod guide having a pump chamber therein;a piston fitting said pump chamber and connected with and operated by said push rod; one or more holes connecting said pump chamber with the interior surface of said push rod guide and one or more holes connecting the interior surface of said push rod with the exterior surface thereof and adapted to alternately come into and recede from opposition with the holes, between said pump chamber and.
the inner surface of said push rod guide, substantially as described.
3. An automatic oilin device for push rods of automobile engines comprising a push rod; a push rod guide having a pump chamber therein; a'.piston fitting-said chamber and connected with and operated by said push rod and a spiral spring situated within said chamber and adapted to be compressed by said piston and operating when compressed to aid in the displacement of the oil in said chamber, substantially as described. In testimony whereof I afiix my signature in presence of two witnesses.
ANDREW C. DANVER.
