INTERNAL-COMBUSTION ENGINES.

Patented July 30, 1918.

To all wrwm it may concern.'

Be it known that we, Gnou. HAMELIN TAYLOR, a citizen of the United States, and BoUoEwIJN B. NnUTEBooM, a subject of the Queen of the Netherlands, residing at Deiroit, county of lVayne, State of Michigan, have invented a certain new and useful lmproverncnt in Castings for Internal-Combustion Engines, and declare the following to be a full, clear, and exact description of the same. such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the ac.

companying drawings= which form a part of this spefication.

Our invention relates to internal combustion engines and a special object of our iniprovenients is to provide an improved lubrieating system.

In the accompanying drawings:

Figure l., is a sectional elevation of a portion of a gas eiigine embodying our invention.

Fi 2, is a sectional plan View, the section icing taken on the line B-B Figs. 1, 5 and 6. i

Fig. 3, is a plan view of the parts shown in Fig. 1, the top or cover being removed,

ig. 4., is a section in the plane indicated by the line DMD Figs. 2, 3 and 5.

Fig. 5, is an elevation of the upper end ot' the part shown in Figs. 1 and 3.

' Fig. 6, is a section on the line F-F Fig. 9 looking from the left of said line.

Fig. 7 is a section of thernold in which the casting forming the body7 of the engine is made showing the cores in place.

Fig. 8, is a detail sectional view on the line H-H Fig. 7.

Fig. 9, is a plan View of the part shown in Fig. 7, the upper portion of the mold being removed.

a a is the Casting forming the bpdy of major portion of the engine. b is the cover or top which is formed se arate from the body u, and is secured in p ace to close the upper end of the cylinders and passages. o is a reservoir for lubricating oil secured at the bottom oli' the casting a. 2 is`the crank case. d is a bearing for the main shaft of the engine. g is the valve actuating counter shaft. e and f are the gear wheels through which the motion from the main shaft is conveyed to the counter shaft g.' The counter shaft g and the gear wheels e f are located in'the crank case and the bearingd j is a partition extending upward from the bottom and into the reservoir z adapted to prevent the oil from flowin `in too large quantities toward one end o said reservolr when it is tilted. lo is a conduit leading from the bearing d to the reservoir z' and extendi over the gear wheel f. Z isan over-flow ipe.. 3 3'* is the crank shaft located Vin tige casing 2 and resting in part in the bearing d. The pipe l is opened at its lower end to the reservoir c and extends a short distance up into the crank case 2 so that oil ing in` the crank case shall llow back through the pipe Z into the reservoir c. m is a small aperture formed through a wall or conduit lc just above the ear wheel f so that a small portion of 4oil owing through the conduit will drop upon the gear wheel f and be thereby conveyed to the gear Wheel e. The gear wheels e and f are located in the crank case 2 so that any excess of oil will flow into said crank case.

fn. (Fig. 4) is a pipe leading to the reservoir zat its upper end and communicating with passages which open through a pipe z beneath the level of the oil'in the reservoir c. o is a non-return valve opening toward the reservoir z' in the passage between said reservoir and the reservoir c. p is a similar valve also located in the passages .forming a communication between said reservoirs. q is a plunger between the valves a and p, by

" the reciprocation of which oil is drawn from the reservoir c and forced through the pipe n into the reservoir Iv' is a cam upon the counter shaft g which cam acts to actuafe the plunger q in a well known maiiner.

.s is a. srall conduit in the casting a, opening at its upper end to the reservoir and having its lower end above the cam r. Oil runs throu h the cdnduit s and drops upon said cam t eV excess flowing into the crank case 2. t, is a conduit similar to s having its upper end opening into the reservoir i and its lowr end opening into a cup-like receptacle w'above one of the intermediate bearings /uf for the main shaft of the engine. v (Fig. G) indicates one of the connecting rods of the en lne which is pivoted to a piston 8 in a cy nder 7.

accumulat- Y is an aperture formed in the bottom of the reservoir z' so that the oil passing there through by gravity shall drop upon the lower end of the connecting rod y and form a lubrication, therefor. 30, 3() are the exhaust ports, and 3l, 31 the' intake. ports, these are ocated in line with each other.

3, 3 indicate water passages forming7 parts of the water jacket or the cylinder 7, 7 formed inthe casting a. 4, indicates one of the exhaust passages of which there are two entirely similar locatedA at opposite ends of the castiu and extending in the same plane longltut inally ofthe casting. 5, indicates the intake passage. This has two branches extending in opposite directions and located al'iproxiinately in the plane of the exhaust passages 4, and also extending longitudinally of the casting. The passages 4 and 5 extend upon opposite sides ol the line of valves and are offset to :ti-vonuuodate their appropriate valves4 i?, is an openingr to the watt-r invia-t in the casting a. 34 indicate the ports to the intake and exhaust valves. 10 is a passage leading upward front the reservoir t'. opening at the top of the casting i through which the reservoir z' may be filled. ll, is a cap adapted to close the upper end of the passage 10. 12, (Fig.1) isan intermediatebean ing for the counter shaft 1H, is a conduit opening at its upper end to the reservoir and at its lower end to the hearing 12 so as to supply lubricating oil to said hearing.

14 (Figxl) is a passage opening to the crank vcase 2 at its lower end and at its upper end to the reservoir z' above the normal level of the oil in said'reservoir. The passage 14 serves as an overflow to prevent too great an accumulation of oil in the reservoir i.

The casting a. is formed in the four-part mold of which the divisions are indicated by the reference figures 15, 16, 17 and 18 in Fig. 7.

19, is the core for the cylinders and crank case. 20, and 23 are the cores for they water passages `of thewater 'aeltets. 1 The core 20 is secured in place by t ie qore'prints 20", 20 resting in the sections 1n ofthe ino-1d and by core prints 20PZ, 2092 also resting in said sections of the mold. The core riuts 20 and 2092 are so located that they 's all form the passages for the water to and from the Water jacket 3.

The core 23 rests upon and is supported by the core 20. I21 and 21 are corresponding cores adapted to form the lexhaust passages 4. These are sup orted in place by the core prints 21", 21 w ichextend laterally and are supported by the core part 16. The prints 21p are so located as to form the exit opening from the passages 21 and 21, 21',

21l are vertically extending core prints reaching from the cores 21, 21, These extend into and are supported by the upper section 15 of the mold and are so located as to form the opening above the ports for the exhaust valves. 22, is a core adapted to forni the intake pipe 5, this is supported by a laterally extending core print 22" and by vertically extending core prints 22W. The mold is divided between the sections 1T and 18 at the larger part of the crank case as indicated at Fig. 7 and between tho ) arts 17 and 18 intermediateY thc portions of t e mold 25, 2G which 'forni the oil reservoir i, the portion 25 being on the part 17 and the portion 26 on the part 16. Said mold is again divided in a line at approximately the-center of the portions forming the inlet and exv haus( passages 4" and 5.
