If the crown head be 145, 5G, and 19, what grist pinion will produce yarn No. 186 from 18 hank rove double, when the carriage gains on the rollers 12J inches in a draw of 54? SOLUTION. Hank rove, 9-J-186 = 20.66 Roller draught Full draw-, 54: 20.66:: 54 full draw. Gaining of the carriage, 12.75 inches. 41.25 Length delivered. Holler draught, 20.66 In the seventeenth draught table, 15.78 inches of roller draught will be found to be the nearest to 15.75 inches K.D., and the grist pinion 31. When double rove go below 9 banks to tbe pound, double the grist of the yarn you intend to spin from, and proceed as before exemplified.--If the crown head be 150, 60, and 26, what grist pinion will reduce 8.8 hank rove double, to No. 64 yarn, when the gaining is 4.5 inches in a draw of 56? SOLUTION. Grist wanted, 64 X 2 Double of jrist wanted, 128 Hank rove, 8.8-f-128 = 14.54 Roller draught. Full length, 56: 14.54:: 56 full length. Gaining of the carriage, 4.5 inches. In the eighteenth table yon will find that 13.37 is uearost to 13.18, and the grist pinion 30. To find how many Nos. a given number of inches gained by the carriage, will add to a given grist of yarn, suppose No. 64. As the length delivered by the rollers: is to the given grist of yarn: : so is the full length of the draw: to the grist obtained with the gaining. If No. 64 be the grist of the yarn given out by the rollers, what grist of yarn will be obtained, allowing the carnage to gain on the rollers 5 inches in a draw of 56? From 56 inches, the full length of the draw, Deduct 5 inches gained by the carriage Length delivered, 51: 64::
