Lessons *and there diverges into a pair of laterale each of, which ends in a short vertical riser, 36 which delivers direetly'rto a chamber 37 in which a pair of inlet Ivalves 355 is arlranged. The laterals from the fuel passageI 35 are Within a easing 38 which is preferably formed integral with the cylinder casting, and immediately above this portion 38` is a horizontal exhaust channel. :39 which is connected to the several exhaust valve chambers 40. ily arranging the fuel supply passage in the manner indicated, the fuel (i. e., the carbureted air) is caused to pass through the water jacket and delivered to Water jacketed inlet chambers and. is therefore eontinuously surrounded with the heated water of the water jacket. The temperature oit this water is always such as to prevent con densation of the gasolene or other hydro carbon but at the saine time preventsthe carbureted airfrom reachinga temperature of combustionbefore it enters a cylinder.

The detachable casing member 14 is provided in its bottom 'with an oil-retaining chamber 4t2, which at its middle is depressed "at 43. Arranged above the, oil chamber l2 are two horizontal shelves 44. Each of these Shelves is flanked at its ends by vertical ribs or flanges 4:5. and at its middle is provided with a flange i6 which is slightly less in height than the llanges The two shelves are separated at their adjacent ende so as to 'orm a passage l? communicating with the depressed portion orf the main cha1nber l2, and the shelves at their ends do not extend to the end oitthe casing, thus leaving openings 48, the arrangement being such that oil discharged upon the shelves 44C will be retained thereon at a depth equal to the height of {ianges' 4i?) and will flow over those flanges into the reservoir l2-JMB. Each of the shelves la is placed beneath a pair of cranks of the crank-shaft, each crank dipping down into the space between flange el@ and one of the flanges 45.

Leading from the lowest point in the de pression lf3 is a strainer outlet 5]. which discharges into pipe leading upwardly to a pump casing 33. This pump is substantially 'lt-shaped, the stem of the l being threaded into the casing; i4 and bored to ceive reciprocating pump 'plunger 5e norn mally urged outwardly by light spring within the casing and at its outer end engagging a cam 5G carried by the cam shazt't :20. The head ot the is pertorated from. end to end and provided with an inlet valve 57 and au outlet valve 5S and leading from the outlet passage beyond 'valve 58 is a pipe 59 which is connected to a pair `of divergent delivery pipes 6l, the ends ot' which pass through easing 14 so as to discharge upon each shellc Communicating with chamber 42 is a vertical supply passage 62 in the upper end of which is rotatably mounted a filling neck or .litting 63, said neck being normally closed by a swinging,T perforated plate 65, the rarrangement being such that' air may have free 'flow into the crank casing through perforations ot the plate but no dirt will enter owingto the `fact that under running con# ditions the filling fitting is presented ddwnwardly. ln order to till the casing with) oil, the vfitting G3 is turned upwardly and plate G5 swung to one side so that lubricating oil may pour freely into the casing until a desired level has been reached,indication ot the level beingl secured by opening cock G6.y

Formed in the main casing' member l0 4between the level oit the crank shaft 15 and cam shaft 20 is a horizontally arranged bea-ring 7l, in which is mounted an intermediate shaft T2. At its outer end shaft. TQ carries.

a coupling member 73 adapted to detachably eopera'te with a coupling member 74 carried by the shaft 75 of a magneto or other generator 76 mounted upon a projecting bracket "(7 carried vby or formed integral with casing member 1th Shaft 72 carries a spiral gear 78 which meshes with a spiral gear 79 on crank shaft l5 and also carries, a spiral gear 8l. which mesheswith a spiral gear 82 carried 'by cam shaft 20.," The two spiral gears 78 and 8l are preferably oppositely pitched so that the thrust of' one will counterbalance the thrust of the other. The inner end of aft 72 is supported in a bear ing 83 carried by the adjacentcap bearingi9.
