WATERCOOLING SYSTEM FOR HYDFOCARBON-ENGINES.

Speeification'of Letters Patent.

Application filed October 2s, 1906. Serial in. 340,238.

To all whom it may concern:

Be it known that I, JAMES W. PACKARD, a citizen of the United States, residing at Lakewood, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Water-Cooling Systems for Hydrocarbon- Engines, of which. the following is a specification.

The present invention relates to means for cooling the various working parts of a hydrocarbon engine and also for cooling the exhaust to assist in condensing and muttling the same.

The invention will be described in connection with the accompanying drawings in which,

Figure 1 is a side elevation partly in section of a four-cylinder hydrocarbon engine embodying the lnvention; Fig. 2 is an end view of the same, partly in section; and Fig. 3 is a plan viewof the lower half of the casing showing the water circulating conduits in dotted lines.

The accompanying drawing illustrates a hydrocarbon engine having four cylinders arranged in line and in pairs, each pair being inclosed within a casing 10. The engine may be of any approved construction and its details will not be described herein as they form no part of the present inven-' tion. The crank shaft 11, as shown, is mounted in bearings 15 in a sectional crank casing comprising an upper section 12, a middle section 13 and a bottom section 14.-. The crank shaft bearings are formed in the upper face of the middle section and the lower face of the upper sect-ion so that by separating these sections the crank shaft may be removed. The lower half of the crank case may, so far as the present inven 'tion is concerned, be formed in a single piece instead of the two

parts

13, 14. The

particular construction of thecrank case is not an essential feature of the present invention except in so far as the water cooling system is concerned. The crank case is partially filled with .oil into which the several cranks dip as the crank shaft rot-ates and the splashing of the oil lubricates thepylinders, crank pins, crank shaft beariiigs'and other parts exposed to the interior of the crank caser I have found it advisable to partially heat ,and stationary motors.

before utilizing it to cool the cylinders. I

also preferably pass the water throughthe casing of the exhaust passage as it flows from the crank case to the cylinder casings for the double purpose of condensing the exhaust and thereby muffling the same and raising the water to a'still'highcr temperature. flows to and through the cylinder casings and from the cylinder casin it may be dis- From the exhaust casing the water charged, although in some instances it lead the water from the cylinder casings into the exhaust pipe .o further cool and condense the exhaust. The invention is particularlyapplicable to marine motors as such motors are not exposed to the cooling effect of the atmosphere as are motors used in motor vehicles, The. invention is however applicable to hydrocarbon motors regardless of' the they may be applied.

The section 13 of the crank case is cored out to forms continuous channel 16 from an inlet 17 to. an outlet 18, as shown in dotted lines in Fig. 3. The channel 16 runs completely around the casing under the end bearings thereof and it is offset inward at each side opposite the middle bearing", as shown in the drawing. All of the bearings, and the oil in the casing, are thus kept cool. The water may be supplied to the inlet 17 in any suitable way. As shown, it is pumped through a pipe 19 by means of a rotary pump 2-0, the shaft 21 of which is driven'in some suitable way by the engine. The pipe 19 conducts the water to the inlet 17 and from said inlet the water flows in the direction of the arrows, Fig. 3, to the outlet 18. From the outlet 18 the water flows through a pipe 22 to the exhaust casing 23.

This casing is suitably cored to produce in.

particular use. to which ternal channels 24 extending lengthwise of the casing and nearlv surrounding the exhaust passage 25. The channels 24 conduct the water to an outlet pipe 26 having two branches 27 which conduct the water to the lower parts of the cylinder casings 10. The water is suitably circulated through these casings and discharged through piping 28 at their upper ends. The water leaving the cylinder casings may be discharged finally as through apipe 29 'or it may be directed into the exhaust passage 25, as through the pipe 30.

Thepipes

29, 30, maybe provided with

valves

31, 32, to direct the water'as desired.

In cases where it is not desirable to permit all of the cooling water to enter the exhaust, I provide an opening 33' between the channel 24 and the'exhaust passage to admit a relatively small quantity of the 2 0 cooling water to the exhaust passage to cool and condense the hot ases, for the purpose of lessening and mu ing the exhaust and also to cool the exhaust pipe to a tempera-- ture at which it will not burn an attendant 25 .or other person touching it. I also provide a valve 34 for the opening "33 and means for locking the valve 1n any desired position. In thedrawing I have illustrated an ordinary needle-valve providedwith means for setting it and a lock nut 55 for holding it in any desired adjustment. I 4 It will be understood that the particular shape and course of the channels in the'various parts of'the motor may be varied and the arrangement of pipes and conduits may be varied without departing from the spirit and scope of the invention. Furthermore the crank case may be made in two parts separated along a plane passing through the 40 shaft bearings instead of three parts as shown. I The invention is furthermore ap-. plicable to engines having more'or less cylinders than the number shown in the draw- As previously stated the invention is particularly desirable "in and applicable to hy-- i I carbon engines for marine purposes, such as motor boats v Y Y -Having-desc 'bed my invention what I desire to secure by Letters Patbon engine, the combina- 1 er having a" water jacket .CBBQCOIIIPIlSlIlg bear ngs trolled means for-conducting a portion of for the crank shaft, of a-"channel in said crank case having transverse portions extending to the crank shaft bearings, means .for circulating water through said channel whereby the bearings are kept cool and the water partially warmed, and means for conducting the water from the crank case to and through the said cylinder water jacket.
