LUMBERING IN PIKE EEGION OP CALIEOENIA. 75 



width may be either 12 or 14 inches. The length of a saw for a 

 9-foot band is 56 feet, and for an 8-foot band the length is 45 feet. 

 The cost f. o. b. San Francisco is $2.25 per foot for 12-inch widths, and 

 $3.15 per foot for 14-inch. 



As the slabs and boards are sawed from the log they fall upon 

 live rolls, consisting of iron cylinders 1 foot m diameter and 2^ or 3 

 feet in length, spaced 4 feet apart in two parallel series extending 

 from each band saw to the trimmer conveyor in the rear of the mill. 

 The rolls are rotated continuously in the direction of the rear of the 

 mill by means of shafting and gears. An off -bearer stands behind each 

 saw for the purpose of seeing that the boards and slabs fall on the 

 rolls free of the saw. 



The boards pass down the Uve rolls until they reach the edgers^ 

 where an automatic transfer removes them to the edger table. An 

 edger is provided for each band saw. The usual type is a 60-inch gang 

 with four or five circular saws. Two men are required at each edger, 

 a pointer and an edgerman. The boards are fed through the edger, 

 the saws having first been adjusted to cut off the edgings and saw the 

 boards into the widths desired. 



From the edgers the lumber and edgings pass to a double series of 

 Hve rolls, about 6 feet wide and 30 feet m length, termed rear edger 

 tables. Underneath these tables there are a number of conveyor 

 chains working toward the side of the mill where the slash saws are 

 located. Two or three men are stationed at the rear edger tables for 

 shoving edgings off onto the slasher conveyor. One of these men 

 also tends the slasher. Slabs do not go through the edgers but pass 

 directly down the rolls and are thrown off on the slasher conveyor by 

 the same three men. The slasher consists of from five to seven circu- 

 lar saws set either 3 or 4 feet apart on a shaft. The slabs and edgings 

 pass under these saws and are cut in lengths for cordwood or lath 

 bolts. 



The rear edger tables deliver the lumber to the trimmer transfer, 

 whore another chain conveyor moves the boards to the trimmer. The 

 trimmer consists of 10 or 1 1 circular saws, mounted in a row. It may 

 be either of the underneath or overhead type and be either hand or 

 pneumatic lift. Its function is to trim off the ends of the boards to 

 standard lengths. After going through the trimmer the boards pass 

 to the sorting table, where the grading and sorting is done. The 

 crew at tlu; trimmer consists of the trimmerman, wlio adjusts the 

 saws, and two men who arrange the boards on the trimmer ta})le. A 

 tliird man is often necessary on the trimmer conveyor. 



A short conveyor is located behinc] the slaslu^r for the purpose 

 of transporting the slabs and edgings to the main conveyor and 

 refuse burner. Lath l)olts and wood are connnonly picked out of this 

 conveyor, when utilized. On tlie low(!r lloor of the jiiill Is locaUul all
