To (rZZwz-om it may concern# Be it known that l, An'rnnnl. BULL, a subject of the Kingof Great Britain, and a resident of Detroit, county of 1Wayne, and
State of Michigan, have'invented certain,
tion engines; and particularly to vthe con-- structionand arrangement of the cooling liquid space orwater jacket `thereof whereby the cylinders and combustion chambers, and the valves and other parts of the engine, are cooled and maintained at a propertemperature for effective operation.
The principal object ofniy invention is to providecertain new and improved features of construction and arrangement in andrelating to thel cooling yliquid j acket'of an internal combustionengine; with the end in view of equal'izing the flow` of cooling liquid to the several parts of the engine to be cooled, so that the various portions in question will be properly and sufliciently cooled when the engine is/in use. g
A further object of Amy invention is to provide an improved cooling jacket construction for internal combustion engines in which the cooling liquid is caused to iiow adjacent the valves of the engine immediately as it enters the cooling liquid space or cooling jacket, and in which means are proyided for regulating the flow of cooling liquid in the vicinity of the valves in such amanner as to secure substantially equal cooling effect as regards each of the valves with which the engine is provided.
A further object of my invention is to provide an improved cooling liquid jacket construct-ion for multiple cylinder' internal combustion engines wherein4 the iiow of cooling liquid is distributed throughout the cylinder block wherein the several cylinders are contained, and throughout the head which closes the upper end of said block in such a manner as to secure proper cooling effect as regards each of the several parts to be cooled; the construction and arrange ment of the` cooling means or jacket structure in question being' such as to secure a supply of cooling liquid directly to the vicinity ofthe valves of the engine in the first instance, and thereafter to cause the cooling .liquid to circulate through thecylinder block, and from thence into the head of the lengine. i
vl/"Vith the .above and other objects of invention in view, my invention consists in the iinploved cooling liquid jacket construction and arrangement for multiple cylinder in- 'ternalv combustion engines illustrated in the `accompanying drawings and hereinafter described and claimed; and in suc-h variations and modifications thereof as will be obvious to thoseskilled inthe art to which my invention relates so long as such modifications come within thescope of the concluding claims wherein the distinguishing features of my invention are particularly pointed out.
Referring now to the drawings wherein the preferred embodiment of my invention is illustrated:

Figure 3 is a view showing a section upon a vertical transverse plane indicated by the lines 3, 3, vFigures l and 2 the impeller of the pump however being omitted. i
Figure l is a view showing a section upon a vertical/transverse pla-ne indicated by the line 4, ll, Figures land 2.
Referring now to the drawings, the reference numeral 5 designates a cylinder block having a plurality of cylinders formed therein as indicated by e.the reference nu lll@ meral 6 and which cylinder bleek is pro- Y i vided with an internal cooling ,liquidl space formed by a jacket surrounding lthe said cylinders, the jacket space within the block being ordinarily common to all the cylinders thereof as is usual in internal comhnsticn engines the type to which my inventien relates.
iet
est) Located Within the space-enclosed by the cooling jacket of the cylinder block is a l vpartition 7, which parti-tion extends longitudinally of the block and is disposed adju-- cent the upper end thereof; the said partinally of the cylinder block and located adja cent the head end thereof, as best shown in Figures 1 and 4. The cooling liquid is supplied to this space or passage through an inlet port l0 which is in communication with the out-let of a: suitable cooling liquid circulating pump; the casing of thepump being designa-'ted by the reference numeral 11 and which pump is illustrated as of the centrifugal type, the rotary impeller thereot` being designa-ted by the reference numeral 12 in Figure 1.
The longitudinally extending partition 7 is shown as provided with a plurality of bosses 13 formed integral therewith as the cylinder'block iscast and which bosses provide bearings for the stems of the several supply and exhaust valves with which the engine is equipped, the seats of said valves being designated by the reference numeral 14 in Figure 4 and which valves are ot the ordinary poppet variety, although theyvare not shown in the drawing; the said valves being obviously arranged along the partition in question, and 'properly spaced relative to the severalpcylinders so as to secure a proper supply of combustible mixture to anda proper flow of burned gases from the several cylinders.
' rlhe partition 7 is shown as provided with a plurality of holes spaced along its length and indicated by the reference numerals 15, and through which holes the cooling liquid which is supplied to the isolated or divided oft portion of the water jacket space 8, as aforesaid may escape ,from theA said space at several points along theD length of the partition; the cooling liquid as it flows l through the holes entering into the main cooling liquid space 9 enclosed by the jacket ot the engine, as will be appreciated. 4'The end of the partition 7 remote from the inlet e5 cooling liquid supplied to the passage 1 ,asiste liquid from the partitioned otl portion 8 of the jacket space at various points provides a coo-ling system in which a supply of con1- paratively cool liquid is secured for the valves which are located remote troni the inlet end 1() o't' the said passage, and secures substantially equal cooling effect as regards each of the valves.
The open upper end ot' the cylinder block is closed by a cylinder head 17 which is hollow to thereby provide an internal cooling liquid or jacket space 'for the head, and the interior of the jacket space of the head placed incommunication with the jacket space of the cylinder block; so that the cooling liquid whichis supplied to the block rises into the hollow head and escapes there from through a manifold or 4passage 18 ot.' gradually increasing area, as best, shown in Figure 2, 'from which passage the same flows through a suitable conduit 19 to the upper end ot' the radiator 20, downward through said radiator, and from the lower end thereofthrough a yconduit 21 to the pump 1l.
Preferably the interior of the cylinder head 17 is placed in communication with both the portions of the jacket space which are separated by' the partition 7, that is with both the isolated portion or passage 8 andiivith the main portion 9 of the said jacket space lthe communication between the the said passage upward, and into the interior of the head providedptor; while the main portion 9 of the jacket space is placed in communication with the interior ot the head through similar passages 23 likewise spaced along the cylinder block and which provide toia iiow ot' cooling liquid Yfrom the said jacket space'into thefinterioi of the head at several points along the length of the block. 'i
The areas oit the several passages Q2, 23. as well also as of the passages 15 provided in the partition 7, are so proportioned as to secure lan equalization of the flow of cooling liquid throughout the entire system wherebjv a proper temperature will be maintained at all the parts oi the engine to be i cooled; 'the holes 15 and 22 being oil re- 2 macerie 'of the jacket-space and from thenceI intol 'the interior Vof the head through the passages 23, as'Will be appreciated, so that all 'the coolingliquid supplied through the port 10 eventually reaches the interior ofv the head and escapes therefrom through the outlet passage 18 to the radiator.
rlhe cooling liquid inlet conduit 21 isi-con nected With an elbow 2li located at one end of the cylinder block; and the cylinder block at the end -in question is provided with an internal chamber 25 into which the cooling liquid is discharged, and which chamber is separated from the-jacket space of the block by a suitable Wall as shown at 26 in ltigure 1. This chamber is p-rovided with an annular outletvopening 27 which lies substantially in the plane of the end of the block and which opening leads into the interior of the'pump casing 11, thus supplying cooling liquid thereto; the said pump casing being detachably secured to the end Wall of the said chamber and of the cylinder block as by means ofa series of bolts 28. The cooling liquid acted upon by the im- 'peller of the pump is discharged therefrom .through an outlet passage A29 which registers with the port 10 above referred to; and the inlet end of the passage 8 adjacent the` outlet passage 29 and port 10 is divided off from the chamber 25 into which the inflowing Water is discharged through the elbow 24 by suitable side and end Walls 30, the outlet passage 31 thus extending through the .inlet chamber 25 of the pump, as /best show-n in Figures 1 and 3 of the drawings.v
The impeller 12 is carried by a combined fan and propeller shaft 32 which isrotatable in a bearing carried by the pump casing 11, as shown,- and the inner end of whichv shaft is preferably steadied by and supported in the end of a bearing provided in a. boss 33 'which' projects from the inner Wall 26 of the cooling liquid receiving chamber 25; and it will be appreciated that the pump features of my invention here'described provide a pump the casing of which is open along one side, and which may therefore be cast Without the'use of a core; and that the entire pump mechanism may be -easily assembled with the engine and is firmly supported therefrom in an easily accessible position. j
