an oil well into which the oil from the various bearings of the motor drains and from which it is drawn and 11e-circulated. A pump forv this purposeis shown at 13 in Fig. 1, the oil being drawn from the bottom of the crank case where it settles through the screen 14, and pumped through a conduit 15 in which there is a pressure regulating valve 16, toa screen 17 and the I 18 surrounding the same. From the chamber 18 the oil is led under pressure through pipes 19-and 2O to the various bearings of the motor. 'Said bearings will be hereinafter further described1v Cylinder blocks 21v are shown as formed separately from the crank case and detachabl secured thereto.

An engine of four c luider. blocks 21 is shown in the illustrative forni of the invention herein, each block comprising three cylinders, two blocks being arranged withtheir cylinders in line and the two pairs of blocks being in V rela tion. Thus a 12 cylinder V type motor is illustrated.

The cylinder blocks 21 are water jacketed as at 22 and suitable inlets 23 and outlets 24 are provided. Each of the cylinders han` an inletport 25 trolled b" puppetvalves 27 and 28.1es ectivey. i )rings 29 maintain these va ves yiel ingly spark plug 30 Vfor each of the cylinders. Y

' A.- carbureter 31 is preferably 'mounted' .in the space between the 'cylinders and branched intake headers 32, one for the cylinders on 'one side'oi the motorand another for the cylinders on the other side of the and an outlet port 26 con-` in closed position, There is a A motor, connect the carburetor with the various intake ports of the cylinders. Suitable exhaust'pipes 33 are connected with the -exhaust ports ofthe motor. n

Mounted in the main bearings of the crank case is a crank shaft 36. In the form shown this crank shaft has similar disks or cheeks 37, all of which. are connected together by the crank pin and main bearing parts of' th'e crank shaft.

The entire gear casing 58 is substantially ot Y form, the lower .part of it extending down around the gear 55, and the upper art being in the Jform of two branches exten ing diagonally upward adjacent to but separated from the rear ends of the cylinder blocks.

' The upper part of each of these branches ofthe gear casing is formed byea detachable esame? cap 84, which as shown particularly in F 2 is provided with an oil filler spout 65. Thus the oilin the crank case may be brought to the proper level by introducing oil through the spout 65, Where it will enter the gear cas ing 58 and run down into the crank case.

l'n the motor herein shown, the camshaft and operating` mechanism for the

valves

27 and 28 are in the forni of a detachable unit lor each of the two pairs of cylinder blocks. Each such unit comprises a tubular cam shaft casing 88 Which extends lengthwise ol the motor and which is mounted on top of and connects the tivo alined cylinder blocks. This casing is divided into several compartments 67, 88 and 69, by

bearings

70, 7l and 72 for front end of the cam shaft 73. A supplementary bearing 72 may be provided as shown in each of' the cornpartinents 67 and 68. The cams 74 formed on the cam shaft 73 are all arranged in .the tvr main compartments 67 and .68 and the cam shaft extends through the front be'ariu?2 and into the end cornpartment 89. his end compartment 69 is very small 'compared with the other cornpartments and is termed largely by a cao 69 screwed on to the end of is supplied With oil under pipe 20 which is a continuation of the pipe 20 shown in Fig. l. Any other equivalent means may be used to supply oil under pressure to this compartment.

The cam shaft 73 is drilled out to malte it hollow and'oil leads 75 are. provided from its interior to eaclrof the

bearings

70, 7l and 72. The rear end of the cani shaft is closed but the :front end is open to the compertinent 69 so that the oil under pressure in that compartment passes into the cani shaft and through the oil leads T5 to the bearings above referred to. The oil flowing from these bearings accumulates in the compartments G7 and 68, which are. interconnected by a channel 78, similar channels 76 being provided in the bearings 72 and from the rear compartment 87 it overflows through the openings 7'? Fig. through the bearing 70 into the gear casing 58 and down into the crank case where it is collected and again circulated as herein above described.

The con'ipartinents 67 and G8 above referred to are formed W 'h top openings 78 above the various cams on the cani shaft 73. Each of these openings has a cover @"9 and between the cover and the casingr is pivotally supported one or more rock shafts 80. Each of these rock shafts 8O is drilled.

out as shown for instance in Figs. l and and has an oil lead 8l leading from its interior to its hearing' surface. An oil cup 82 is also formed in the upper part of the rock .shalt and a downwardly extending lug` 88 on the Cover T9 directly over the cup 82 causes soule or the oil splashed up onto the cover to dep into the cup. This oil then the casing. t. pressure by trains ofgears Which passes into 'the roel; shaft 8C and to its been v in# surface.

ach roclr shaft has an arm 84 upon which is a roller 85 in contact with one of the earns 74's of the caro s raft, and the end ot the rock shaft 8O that extends outside of the cam shaft casing is provided with an arm 86 haring an adjustable plunger 87 in contact with the stem of one ot the

valves

27 and 28.

From the above description it will be seen that the camshaft casing 66, the camshaft, and all of the rock shafts and other operatarts may be assembled before the unit is aced on the motor. lt may then be attached to the tops of the cylinder blocks by the lugs 88 and bolts 89. It may also be secured to the gear casingr 58 by the cap 64 Whichhas a part 9() cooperating with a part 91 on the gear casing, which parts are arranged to clamp the tubular `casing; G6 between them. Endwise movement or' the tubular casing 66 relative to the gear casing 58 is prevented by reason of the llanges 92 on the tubular casing. By this connection of` casings and cylinder blocks a very strong and ri id construction is obtained. l

gThe spur gear on the crank shaft has been herein above referred to. This gear forms one oic a train 01"' gears between the crankshaft and an auxiliary shallJ 93 which, )in the forni ofy the invention shown, is mounted directly above and parallel to the cra-nir shaft. This auxiliary shaft 93 is mounted in bearings 94 and :95 in the gear casing 58 and is shown connected Witha generator 97 for supplying electric current to the spark plu s of the motor. The generator .is mounts on a bracket 98 arranged between the cylinder; blocks.

Freni the auxiliaryshaft 93 there are two extend in opposite direction and are arranged to operate the two earn shaft at ouehalt crank shaft speed, Of these trains of gears, only several gears of one of the trains areherein shown., including a gear 107 nieshin with an idler gear 109, which meshes with cured to the rear end of one of the cam shafts T3. A similar idler gearlOQ meshes with the gear 108 and .itsell meshes with a gear ll() on the other cam` shaft 78. lt will be understood that the gear 106 has just half as many teeth/as each of the gears lll), so that the cam shaft 73 will operate at one! half crank shaft speer, for operatingthe motor on the four stroke cycle. I

All of the gears above referred to are shown as of the straight tooth spur type but it Will be understood that other equivalent gears may be used for the saine purpose..

Referring to the arrangement oll the cam shaft casing' and the gear casing', it will be seen that the former niay be reniorcd by removing the bolts 89 and the caps4 (it. `rAlso the upper part 6l of the gear ca/*sing may bc a gear ll() seof me @aging will deacned and @his par@ 110% am. il@ ma wel Hm uppe parts 01E ha waiving@ ohm gems 106, l0? ami 108.
