Obviously the latter approaches nearer to the three-point ideal, and, compared with some single front endsuspensions, is clearly a cheaper arrangement to pro-duce. But, like the Galloway arrangement, it is a four-point suspension, nevertheless, and something has toyield when there is frame distortion; probably the framewebs accommodate themselves to the conditions of themoment. The hemispherical trunnion bearing for the nose ofthe crankcase, somewhat on the lines of that shown inFig. 3, is most usually favored by engine designers with GAlXOVAf BELSIZE Fig-. 4-.

In the case illustratedthe cross member is an angle casting with stiffeningwebs each side of the center, as shown; but as a rule apressing of the usual channel section is favored, whichnecessitates a modification of the trunnion bracket—unless there is a pronounced dip in the cross memberor a relatively high crankshaft center. This modificationgenerally consists of securing the bracket to the verticalweb of the pressing by horizontal bolts. But whetherthe bracket be supported as shown or otherwise, a splitbronze bushing with a parallel bore and hemisphericalexterior surface is almost invariably an accompaniment,with a grease cup in the bracket cap. What is probably unique in front end engine mount-ings is the arrangement shown in Figs. 4 and 5, whichis used on the Belsize, a medium-price
