The invention contemplates the arrangement the transmission shaft since both of these gears, in parallel relation and in a common crank-case on their facing sides. are formed with clutch ele I0 of the crank shaft II and transmission sh'aft ments designed to be selectively engaged with the clutch member 25 which is mounted on the trans I2 of the engine or motor whose cylinder Il sur mission shaft between the gears 2U and ll and 50 ' l 50 mounts 4the crank-case and is .of the usual air is axially movable of the transmission shaft but cooled variety and equipped with the conven „ , tional inlet and exhaust valves actuated by push `precluded from angular or turning movement rods i5 bearing respectively on the cams I8 and with respect thereto, as by being keyed to the transmission shaft. Shifting of the clutch mem Il. y 55 V'l‘he‘cams il and I1 are formed as elements oi' ber Ii is accomplished by means of the shifter '55 2 2,127,884 38 which is provided with any sui? ible actuating means 31. The transmission or power shaft i2 extends far enough through the sleeve 3i to provide a mounting for the starting gear 38 which is op eratively connected with the transmission shaft through a conventional overrunning clutch I9, or its equivalent, so that if movement is imparted to the gear 38, the transmission shaft will be turned as a result, whereas if the transmission shaft is turning from power derived from the motor, the gear may remain at rest. In m'esh with the gear 28 is a segment 48 designed to have an angular or turning movement imparted 15 to it through the starting treadle Il. In starting the motor, the elements of the intermediate and full transmission shaft speed ' to the sprocket 62. The clutch 53 is interposed between the trans mission shaft 52 and the cam shaft 61 which is in the form of a sleeve loosely surrounding the Cî transmission shaft. The cams 65 respectively actuate rockers 68 ' and 69 which in turn respectively actuated the intake and exhaust valve push rods 10 and 1|. -In that form of the invention illustrated in Figure 5, the construction is modified to the ex tent of having the drive clutch 80, which is sub stantially identical to the drive clutch 53, con nected with and driving anelement of the trans mission shaft, this element being in the form of a short tubular shaft 8| in which the pilot clutch 22 will be engaged but the clutch mem 82 of the main portion of the transmission shaft ber 3l will be in neutral position. Depression ' 83 is received. The cams 84, which operate the of the started treadie 4| will impart angular valve rockers are identical in contour with the 20 movement to the sector 40 which, through the cams 65 which are preferably integrally formed gear 38, will effect angular or turning move on a sleeve extension 85 of the driving member ment of the transmission shaft I2, turning move of the clutch 88, the shaft 8| rotating in the ment to the cam shaft I8 being imparted through sleeve extension of the clutch, which sleeve ex the clutch22. But with the turning of the cam . tension rotates on anti-friction bearings in the 25 shaft, the crank shaft will also be turned -and wall of the transmission case 86. the motor will be set in operation. But then the A gear 81 .carried at the end of the shaft 8i transmission shaft will turn through power de and integral with or secured thereto is provided rived from the cylinders. Starting of the ve with clutch lugs on one side and this gear meshes hicle is accomplished by first releasing the clutch with the gear 88 on a counter-shaft 89 substan 30 22 by actuation of the rod 2l through its finger tially identical with the counter-shaft 54. The 28, sothat the clutch member 35 may be shifted into engagement with the lgear Il, when the sprocket 33 will be turned from its transmission gear 88 is mounted in common with the gears 90 and 9i on a sleeve 92, the gear 9| meshing with a gear 93 floating on the section 83 of the shaft through the gear train 34, 28, 38a and 39, transmission shaft, this portion of the transmis sion shaft extending to the exterior of the trans mission case 86 and carrying the drive sprocket 94. The section 83 of the transmission shaft is splined, as indicated at 95, so that the gear 96, which is mounted on this section of the shaft, may move axially with reference to the trans mission shaft but not angularly with respect thereto. The gear 96 is provided with clutch lugs on opposite faces so that it may be interlocked either with the gear 81,' or interlocked with the 35 thus giving a lower angular speed to the sprocket Il than that at which the transmission shaft turns. Shifting to high speed is accomplished by first declutching. as aforesaid. and then shift ing the clutch member 35 into‘ engagement with the gear 2l, when the angular speed of the sprock et 38 will be the same as that at which the trans mission shaft turns. In that form of the invention illustrated in 45 Figure 3, synchronous'operation of the crank shaft and transmission shaft is effected by a positive operative connection between the two which may be in the form of a chain traversing. sprockets on the two shafts or in the form of a gear couple of which the driver 88 is carried by the crank shaft and the driven Il by the tra’ns 30 gear 82.
