ROBERT E. BEAUBIEN, OF CHICAGO, ILLINOIS.
FORCE-FEED ENGINE-LUBRICATOR.
Specification of Letters Patent. Patefited Dec, 16, 1919.
Application filed April 10, 1919. Serial No. 288,942.
To all whom it may concern:
Be it known that 1, ROBERT E. BEAUBIEN, citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Force-Feed Engine-Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to lubricating systems for internal combustion engines, its general objects being to provide a simple and inexpensive oil pump so constructed that it can easily and efiectively be attached to a completely manufactured engine for operation by the valve-actuating mechanism without requiring any machining of the original engine parts. More particularly, my invention aims to provide an oil pump adapted to be operated by a connecting arm interposed between the valve stem and the push rod of a puppet engine valve, and to provide simple means for preventing this connecting arm from rocking, to provide a simple and easily attached mounting for the oil pump, and to utilize the valve spring for holding the connecting member in effective operative position. Still further objects will appear from the following specification and from the accompanying drawings, which drawings show my invention as applied to the ordinary Ford automobile engine. In the drawings,
Figure 1 is a vertical section through one of the valves of a Ford engine and the mechanism for operating the latter, showing the oil pump of my invention as attached to the same.
Fig. 2 is a perspective view of the cover plate carrying the oil pump, and of the oil pipes and dash gage connected to the same.
Fig. 3 is a vertical section taken centrally through the pump parallel to the face of the cover plate carrying the latter, and showing the check valves and pipe connections of the pump. I
Fig. 4 is a perspective view of the member which operatively connects the plunger of the oil pump with the valve stem and pushrod of the engine.
Fig. 5 is a perspective view of a pump plunger and a connecting member arranged for use without a spring in the cylinder of the pump.
In the engines as now used on Ford automobiles, each valve stem is raised at the proper time by a push-rod abutting against the lower end of the valve stem, the rais ing of the push-rod being effected by a cam, and both the valve stem and the pushrod being returned by a spring. The'adjacent ends of the valve stems and the pushrods, as well as the retracting springs for the several valves are housed by a recess in the engine casting, to which recess access is afforded by a plate which is laterally guided and which is held in its normal position by a single bolt extending through a perforation in this plate. In applying my invention to such an engine, I remove this plate and substitute for it a plate of corresponding outside dimensions, which substitute plate 1 carries a pump cylinder 2 closed at its upper end by a cap 8. When this substitute plate is in position, the pump cylinder extends vertically parallel to, and directly opposite, one of the valve stems 4 of the engine. Between this stem 4. and the adjacent plunger 5 I insert an operating member 6 having one end thereof bent back parallel to its main portion and perforated with a bore corresponding to the outside diameter of the valve stem 4. The main portion of this connecting member is inserted between the adjacent ends of the valve stem and the push-rod, with the valve stem extending through the perforation in the connecting. member and clamping the connecting member between itself and the push-rod. The free end of the main portion of this connecting member 6 extends through an opening in the plate 1 into the pumpcylinder and supports the plunger 7 of the pump, which plunger is continuously urged downward by a light spring 8 interposed between the plunger and the cap 3. Thus arranged, the reciproication of the push-rod 5 and the valve stem 4: by the cooperating action of the cam 9 and the spring 10 will raise and lower the plunger 7 of the pump with each reciprocation of the valve. Consequently, each downward movement of the plunger 7 will draw oil in through the lateral inlet 11 of the pump, and each raising of the plunger 7 will force oil out through'the outlet 12, the said inlet and outlet being provided with suitable check valves, such as the balls shown in Fig. 2. In practice, the inlet 11 may be connected through a pipe 13 with the pit of the engine, while the outlet 12 is connected through a pipe let to the bearings which are to be lubricated, this connection being desirably made through a glass covered gage 15 mounted on the dash 16 of the automobile after the manner shown somewhat diagrammatically in Fig. 4.
lVith the parts thus arranged, it will be obvious from the description, that after re moving the ordinary valve cover of the engine, the valve stem l can readily be pried up, so as to permit of slipping the connecting member 6 into position. Then by simply substituting the cover 1 and the pump parts carried thereby, for the original valve cover, and bolting this plate 1 in position, the oil pump will be operatively mounted without any drilling or other work on the original engine parts. By making the bore in the shorter end of the member 6 a close fit for the valve stem 4, I avoid a rocking of this connecting member with respect to the valve stem, so that the pump plunger 7 is moved in unison with the valve stem and for the same distance. Consequently, by making the cylinder of the pump of a suitable diameter, I can readily obtain a sufiicient displacement in a pump cylinder to afford an effective oil circulation even with the relatively small lift of the cam 9.
However, while I have illustrated and described my invention as applied to the engine of a Ford automobile and as having the plunger 7 of the pump continuously pressed against the connecting member 6 by a relatively light spring 8, I do not wish to be limited to the construction and arrangement here disclosed, it being obvious that the same might be varied in many ways without departing from the spirit of my invention. For example, the plunger of the pump might have a groove turned in the same near its lower end and this groove might be straddled by a fork in the longer end of the connecting member, as shown in Fig. 5, thereby avoiding the need of a spring 8 while still moving the plunger of the pump in unison with the adjacent push-rod.
I claim as my invention:
1. The combination with a puppet valve stem and a push-rod in alinement therewith, of an oil pump disposed with its plunger parallel to the said stem, and a connecting member clamped between the said stem and rod and engaging the pump plunger for operating the latter conjointly with the movement of the valve stem.
2. The combination with a puppet valve stem, a push rod alined therewith and adapted to raise the stem, spring continuously forcing the stem toward the rod, an
oil pump having its plunger disposed parallel to the said stem, and a member rigidly connecting the said stem and plunger for operating the plunger conjointly with the stem, the said member being clamped between the adjacent ends of the stem and push-rod by the pressure of the said spring.
3. Mechanism as per claim 2, in which the connecting member has one end bent back upon itself and perforated to permit the valve stem to extend therethrough, whereby the wall of the said perforation cooperates with the clamping pressure of the spring in preventing the connecting member from rocking with respect to the valve stem.
4. The combination with a slidable valve stem, of an oil pump disposed with its plunger parallel to the said stem, and means rigidly connecting the said stem plunger for causing a movement of the valve stem to operate the plunger of the pump conj ointly therewith.
5. Mechanism as per claim a, in which the connecting means are slidably and manually attachable to the valve stem.
6. The combination with a slidable valve stem and a push-rod in alinement therewith, of an oil pump disposed with its plunger parallel to the said stem, and a connecting member clamped between the said stem and rod and engaging one of the last named two members for preventing a rocking thereof with respect to the said members, the said connecting member being operatively connected to the plunger of the pump for op erating the latter conjointly with the movement of the said push-rod and stem.
7. Mechanism as per claim 1, in combination with spring means continuously pressing the plunger of the pump against the connecting member.
8. In an internal combustion engine having a slidable valve stem moved in one direction by the movement of a push-rod abutting against the end of the. said stem and having the adjacent ends of the valve stem and push-rod housed in a recess, a plate covering the opening of the recess and extending parallel to the valve stem, a pump cylinder carried by the plate and also ex tending parallel to the valve stem and hav ing an opening from the cylinder into the said recess, and means extending through the said opening and operatively connecting the valve stem and the plunger of the pump for causing a movement of the said stem to move the plunger of the pump in unison with the stem and in the same direction therewith.
