222 CONSTRUCTION OF MACHINES. [Clmp. 11.

5. To hoist the wheat from a shelling-mill, if there beone.

One elevator may effect all these objects in a mill right-ly planned, and most of them can be accomplished inmills ready built.

Suppose it be wished to hoist about 300 bushels in anhour, make the strap 4^ inches wide, of good, strong,white harness leather, in one thickness. It must be cutand joined together in a straight line, with the thickest,and, consequently, the thinnest ends together, so that ifthey be too thin, they may be lapped over and doubled,until they are thick enough singly. Then, to makewooden buckets, take the but of a willow or water birch,that will split freely; cut it in bolts, 15 inches long, andrive and shave it into staves, 5^ inches wide, and three-eighths of an inch thick; these will make one bucket, each.Set a pair of compasses to the width of the strap, andmake the sides and middle of the bucket equal thereto atthe mouth, but let the sides be only two-thirds of thatwidth at the bottom, which will make it of the form offig. 9, Plate VI.; the ends being cut a little circular, tomake the buckets lie more closely to the strap and wheel,as it passes over. Make a pattern of the form of fig. 9,by which to describe all the rest. This makes a bucketof a neat form, to hold about 75 solid inches, or somewhatmore than a quart. To make them bend to a square atthe corners e c, cut a mitre square across where they areto bend, about 2-8ths through; boil them and bend themhot, tacking a strip of leather across them, to hold themin that form until they get cold, and then put bottoms tothem of the thin skirts of the harness leather. Thesebottoms are to extend from the lower end to the strapthat binds it on. To fasten them on well, and with de-spatch, prepare a number of straps, If inches wide, ofthe best cuttings of the harness leather; wet them andstretch them as hard as possible, which reduces theirwidth to about l£ inches. Nail one of these straps tothe side of a bucket, with 5 or 6 strong tacks that willreach through the bucket, and clinch inside. Then takeall inch chisel, and strike it through the main strap
