Fig. 4, is a side elevation showing the main casting of the frame and one of the cylinder castings and attached parts separated from the frame. Fig. 5, 1s a section on the line E-E Fig. 1 looking from the left of said line..-

a a indicates the engine casing as a whole, and b b is the frame or main casting to which the other parts of the casing are secured.

c is the bottom, or oil pan, of the caslng.

d is a cover extending over the portion of the frame between the cylinder casting and inclosing part of the mechanism.

e is a housingor extension from the easing 1) which extends over the fly wheel 40 and is-extended laterally to form lugs, or supports, it h for the engine.

f is a casing at one end of the frame or casting b inclosing some of the mechanism of the engine.

g, g indicate a pair of lateral extenslons at one end of the casting 6, serving as lugs to support the engine at this end while the lugs h it above described support the engine at the other end.

The covers 25 fit against the surface 22* and are bolted thereto to cover the cylinders. The castings 2222 are finished off along their faces 23-24 at right angles to each other and fit against the side edges of the upwardly extending partitions z j Z and the uppbr edges 4 of the side walls m and the upper edges of the end walls 0 p and are secured in this position by bolts, as shown in Figs. 2 and 26-26 are the valves, the stems of Which extend inwardly toward each other and are acted on by the cams on the shaft 19, as indicated most distinctly in Fig. 2. This valve construction is particularly described and claimed in a copending application filed January 21, 1915, Serial No. 3435 of 1915.

The exhaust passages 30 open through the flat horizontal uppersurfaces of the casting 2222 and cast aluminum manifolds 2727 are secured by bolts on said surface so that the passages 30 shall open into said manifold. The bottom, or oil, pan 0 is secured to the

lower edges

2, 3 of the walls m and together with said walls form the inclosed crankcase. An air pump may be mounted upon the front of the frame I; as shown and means provided to removably couple said pump to the shaft 19. By this means facilities are afforded for'inflating the tires.
