RE 40/50 H.P. REAR ENGINE FOOT. X.4062 N. SCHEME 364. RECEIVED In accordance with Mr. Royce's directions, I send you herewith his criticisms of the above scheme as follows. Do not use washers between the engine foot and the frame, but use large taper washers underneath the bolt heads on the outside of the frame. The bottom edge of the foot may be cut off so as to fit in to the frame where the radius occurs in the latter part at the bottom corner. The alignment of the engine is to be effected by sliding the cantilever part of the foot on the standard. The former piece will be split on one side, and have bolt bosses for clamping to the standard, as shewn in the sketch - The idea is that when the chassis are sent on test they shall be clamped by the bolts, but there will be nothing else to hold the engine. After the chassis have been through the road testing and have settled down they can be easily re-aligned, and when the correct position has been found, the hole for the dowel screw can be drilled in position on the chassis. The drilling of this hole can be accomplished by making a small hole first, the drilling being guided by a screwed bush in the 1/4" tapped hole in the cantilever. The small hole can afterwards be opened out to the full size required. The dowel screw should be locked with a sheet metal washer. (Contd.) | ||
