HYDROCABBON-MOTOR.

Specification of Letters -Ilatent. Patented Sept. 16, 1919.

Application filed November 11,1915, Serial'Nu. 60,813.

To all iii/tom it may concern Y Be it known that I, DORSAY ,MCCALL Winnie, a loyal subject of the King of England, and resident of Detroit, Wayne county, State of Michigan, have invented certain newand useful Improvements in Hydro-I carbon-Motors, of which the following is a specilication. This invention relates tohydrocarbon molO tors, and particularly to hydrocarbon motors of the so called \f typo.

One of the objects of this invention is a novel arrangement and construction of the valve. operating,r mechanism of a V type motor.

Another object is to provide a Valve ,operating mechanism, uhich is Asimple in construction and efficient in operation; which may be easily assembled and disassembled 2o and is comparatively inexpensive to manufacture. v

Another object of this invention is to pre vide a motor of the V type. having its valves and operating mechanism so arranged that the valve mechanism of opposite cylinders muy be operated by the same cam, or cams,

through suitable intermediate' members or roi-ker arms, which may be assembledA in position and disassembled therefrom, without disturbing correlated parts, such as the cam sha1" t and the valve mechanism proper; and to provide a valve mechanism havin tlnse parts so arranged that the lift on the talipets will he straight upward, instead of having;r a lateral thrust component, as in previous valve operating mechanisms of this type. i.

Other objects will appear from the followingdescrption. taken in connection with 4G the drawings, which form a part of this specification. and in which:

Figure 1 is a longitudinal vertical section,

.substantially on the line 1 1 of Fig. 2

of a motor embodying a form of this inveni5 fion. showing parts broken away;

Fig. 2 is a transverse view, showingr parts broken away;

Fig. I3 shows a side view of an assembly of a prateria-.d form of valve operating rocker arms and supporting members;

Fi 4: shows a face view looking upwa'd y, of the assembly shown in. Flg. 3; an Y l Fig. 5 is an enlarged fragmentary view of the valve operating mechanism. `5

Referring to the drawings, l0 represents the motor lbase or crank casc on which is suitably mounted in V relation a plurality of cylinder blocks 11 and 12, which are secured thereto, as by bolts 13. The cylinders are. provided,y with pistons 14,- Which are adapted to 'be connected with 'the crankshaft 15 by means 4of connecting r'ods 16 and 17, suitably attachedV at their upper ends to the pistons 14, by means of the usual piston pins 18- i Y The crank shaft 15 may be mounted in suitable`be'arings 19 in thecrank vcase 10, which are secured therein by means of detachable caps 20and bolts 21. It will be 70 noted that as the cylinders in the blocks 11 and 12 are arranged opposite each other, one of each of the connecting rods 16 and 17 are adapted to vbe journaled on a single crank 22. This may be done by providing one of the connecting rods, such as 16, with a forked portion 16',l which has suitably se cured thereto, as by pins 18, a journal member 19, which may be secured in position in 'the detachable caps 23, as by bolts 24. The 8o other connecting rod 17 is adapted to be sleeved within the yoke arms on the journal member 19 and secured in position, as by cap 254 and bolts 26. Arranged adjacent one end of the crank shaft 15 is a driving gear 85 27, which may be secured thereto, as by a. bolt 28, and a ily Wheel 29 may be secured to 'the opposite end of the crank shaft by bolts 30.

Each of the cylinders is provided with an inlet valveand an exhaust valve mecha nism, arranged in the adjacent or inner sides of the cylinders and comprising a bushing31, suitably arranged in the upper portion of the cylinder and having mounted therein a valve 32 of the puppet type, which is provided with a collar 33, arrangedon the stem 34 thereof. .A valveclosmg s rlng 4 35 is suitably arranged between the cylinder and the collar 33. Adjustable4 tappets 36 100 driving 1t, such as 'gear 43",- jn the form of a ch A U `vided. i cover plate 46 for. the drlving l mechanism, arranged at the front 'end vof cylinder blocks arms 54 .and 55 are arranged in bushings 37, wliibl'in'i'ay behel -in position .in the crankca'se 10, as by a pressed fit, and arranged ,onthe up per end of the tappi-.its is 11n-adjustable contact portion 36 wh'ic sition by nuts 38 arranged on the different parts of the tappetsfor adjusting a proper clearance between the valve stem` '34 and tappets 3G. The actuating means Afor the valfv'es will new be more particularly. described.-

This cani shaftlmay be secured in position by ranssi'lch asa pin 42, and may be provided with 'means for a gear/43,' Winch isar-" izit''e'd adjacentits front end and adapted f "eseured thereto, as by a `bolt 44. A driv'fiiigf connection from' the gear 27 tothe ain It5 is protlie motor, may be 10,as by b olts 47. lt will he understoodthat the crank-case is provided at its upper side with an'opening 48, lwhich is adapted to be closed-by a cover or supporting plate 49, which may be secured in position asl by bolts '.50. The supporting plate 49. is provided with a plu'- rality of sets of downwardly extending lugs 51 and 5l', Lin which are arranged 'suitable bushings 52 for supporting nods 53 and 53', respectively.. It will be"understood that in an eight cylinder motor, as illustrated, having its cylinders arranged at a ninety degree angle, each of the canis'is adapted .to operate two valves arranged in opposite cylinders, as shown.

These rocker are held in prdper relation by means of the spacers 56, which may be secured to
