To all whom it may 0mm; w ,Be 1t known that I, VVILLIAMSHxBEN- NETT, a citizen of-the United States ofAmeiw ica, and resident ofAuburn in-thecount-y of Cayuga, in the State of'Ne'W York, have invented new and useful Improvements in Internal-Combustion Engines,-of which the; following, taken in connection with the ac companying drawings, isa full, clear, and

chambers insufficiently spaced relation to enable them to be water-jacketed through 1 out the greater'portions of their areas in .7 such a manner that the major-portionsof the jackets will be exposed to atmospheric air for additional cooling purposes and at the same time to maintain communication between said jackets and that which surrounds the cylinders. V Y
Another 0 ject is'to provide for the cirr cul'ation of the cooling agent entirely through both of the valves as a part of the same system by which the cooling agent is circulated through the ackets of the-valvecasings and'cylinders; c.

'A still further object i m" divide the valve casings in such a manner that the outer halves may be removed for inspection or repairs of the-correspondingvalves and also topermit the casings-tovbe fitted more'closely to said valves by the use of-suitable shims.
Other objects and uses relating to' specific parts of the engine will be brought out in the following description. i In the drawings:

The engine showncomprises a plurality of, in this instance, six cylinders lee-east enbloc in 'an upright position and mounted V a s r v c .7 upona suitable base or crank-case 4-c2 for Qne of the objects is to arrange'the'valve- 7 receiving a corresponding number vof .re-
ten-against ,endwise movement." I These'valve-casings are preferably spaced 7 adjacent ends of the valvesto hold the :lat-- asuliicient distance apart at opposite sides I of' the cylinders to 1 enable the. greater portions thereof to be exposed tothe :atrnosphere for Tcoolingfpurposes-and are pro- .95 a: "vided with lengthwisecircularbores-'for're ceivingseparate rotary valves and I with a series, of iii-thisinstance six intake- 1 ports lO one for each .cylinder while responding numberof outlet portsil also oneforeachcylinder; V t N p 7 The valves '8 and .9are similar in construction,, each being provided with a "circular lengthwise opening r-.l 2's ex;tend- -ing therethrough fromend tofend, andicircum ferentially' elongated peripheral peckets That is, the relation of each intake pocket 13 to its inlet ports -4- and 10--and also the relation of each exhaust pocket -13- to itsports -5 and 11 of the same cylinder are such as to cause the valve 8 to close the fuel-inlet, and the valve 9 to open the exhaust during the exhaust stroke of the piston 3- from the position shown in Figure -3, immediately following which or during the next succeeding suction stroke of the piston, the valve -8- will be adjusted to open the fuel-intake while the valve 9 will close the exhaust, whereupon during the next succeeding compression and firing strokes, both valves will have been adjusted to close the intake and exhaust of that cylinder, so that the piston of said cylinder will then be in the first position mentioned or as shown in Figure -3 ready for a repetition of the operations just described.
The spark-plug, as -14 is preferably secured in the head of the cylinder, midway between the valve casings 6 and 7- so as to bring its terminals in adirect line between the inlet-port l-- and exhaustport 5, thus causing'the inflowing explosive mixture to impinge directly against the terminals for more speedv and effective ignition and also tending, in a measure'to clean and cool said terminals.
The major portions of the walls of the cylinders -1 and valve casings -6 and 7 are hollow to form water jackets 1F communicating with each other to establish a single circulatory system for water or other cooling agents.
' The central lengthwise openings l2 through the valves 8+ and -.9 also form a part of the same circulatory system and for this purpose each communicates at one end (preferably its rear end) with a chamber 16- in the'corresponding end of the valvecase, said chamber being connected by a radial opening -l7 with a conduit 18- leading to the adjacent end of the water jacket 15-. I
The opposite or front end of the opening 12- of each valve communicates with an adjacent chamber -19- in the corresponding end of its valve-case, said chamber being provided with a radial inlet 2() which is adapted to be connected by a flexible pipe 2l to the bottom of a radiator not shown, but in a manner well understood in this art.
In order to complete the circulatory system,
flows through the openings -12-- in the valves -8 and 9 into the rear end.
chamber 16 and thence through the. outlets -l7 and pipe '18 into the rearendv of the water-jacket 15 to completely fill said jacket for taking up the heat from the cylinders and valves, after which the heated water or other, cooling agent is conducted through the outlet -22- and pipe 23;- back to the top of the radiator in which the heated cooling agent is cooled and the circu lation repeated in the manner just described.
It is preferable to provide some means for forcibly circulating this cooling agent rather than to rely wholly upon the automatic siphoning action and for this purpose I have provided the front ends of each of the rotary valves with impeller vanes 24, arranged in such a manner as to constitute with the adjacent ends of the valves rotary pumps by which the water or other cooling agent is drawn from the bottom of the radiator throu h the pipe 21- and inlet 20 into t e chambers -19 and is then forced through the valves and remaining portions of the circulatorysystem in the manner previously described. The opposite ends of each valve are pro vided with annular flanges 25 adapted to ride against the inner end walls of the chambers 16- and -19- to hold said valves against endwise movement, the outer end walls, as -26 and 27 of each of said chambers being removable to permit access to the adjacentends of the valves if desired. j V p i 7 Both of the valve-casings --6-,. and 7 are preferably divided diametrically throughout the entire lengthsof the valves, so that the outer halves thereof, as shown more clearly in Figures 2--- and 3- may be removed to permit. the removal and replacement and adjustment of either valve without disturbing the other valve or itsbearing, said removable sections being normally secured in place by bolts 28 which permits the use of thin shims if necessary to produce the desired fit of the valves in their respective chambers.
The front ends of the valves are provided with shafts 29 journaled in suitable stuffing-boxes -30 in the adjacent end walls of the chambers --19-and are provided with sprockets 31-, connecte d by a belt 32 for transmitting rotary motion from one valve to the other in the same direction. a V V 7 One of the shafts is provided with an additional sprocket -33 adaptedtobe connected by a belt 3 l to the crank-shaft, as 35- of the engine, the means for transmitting motion from the crank-shaft to the valves being shown more or less diametrically in Figure 5.
' What I claim is:
In an internal combustion engine, a series of upright cyllnders arranged 1n tandem and provided with separate sets of ports in opposite sides thereof, cylindrical valve chambers extending continuously acrossboth sides of said cylinders and communicating with the adjacent ports and ';having their opposite a cooling liquid through the. valves, means for rotat ng said valves, and impellers se-- i cured lto'one' end of said valves-to rotate therewith wholly within the adjacent enlargements' of the valve chambersp,
In witness whereof I have hereunto'set my hand this eighth'day of October, 1918..
