When an engine is to be located permanently it is best to mount it on a concrete foundation as shown above. In the table each letter shows the distance between the points as indicated in the drawing above.     To make a foundation like this dig a hole as long and wide as indicated by "F" and "G" and as deep as the sum of "E" and "H." If ground is not solid line hole with lumber or sheet metal to prevent caving. Make a box or frame without top or bottom of size as indicated by C, D and E. Across the top of this box securely attach a couple of strips 2 or 3 inches wide, thickness as indicated by "J" and spaced as indicated by "A," measuring from center to center. These strips should be long enough to reach clear across the hole for foundation and box hung in the center of it. The top edge of box must be perfectly level. In the cross strips bore holes of size as indicated by "K" spaced as indicated by "A" and "B." Foundation bolts of length indicated by "L" fitted with large washers on the bottom should be hung from the cross strips. A piece of pipe or tubing larger than the bolt should be placed on the bolts as indicated by the dotted lines in the diagram. The pipe or tubing should come about 1/4 inch below the top of the cross pieces and is put in so bolts can be shifted on account of a variation In the bolt holes in the engine base.     If engine is to be raised from ground the measurement "E" and length of bolts "L" should be Increased to correspond with the height of foundation above ground but measurements below ground must not be changed.     The concrete should be made up of one part good Portland cement, two parts clean sharp sand and four parts clean gravel or crushed stone. Mix thoroughly while dry and then add water, again mixing well till you have a slushy even colored mixture. Place this in the foundation hole, tamping solidly. fill up to within 1/2 inch of the top of the, box. Then fill up the, remaining space with a mixture of one part cement and two parts sand mixed thoroughly and moistened sufficiently so it can be spread and troweled smooth. Let the foundation set for two or three days when the wood forms can be removed and space around foundation be filled with earth or cinders. Then mix cement and water about like thick cream and fill the spaces between the pipe and bolts. Mount the engine, put nuts on bolts and screw down tight. It will be best to let the foundation harden for at least a week or ten days before using the engine. -11-
