NETT HARDWOOD LUMBER COMPANY, MEMrillS. TENN. 



SAWMILL I'LANT OF THE liEN- 



of about thirty-five hundred feet are made hourly. The system 

 works with equal effieieucy on gum, oak, chestnut and all other 

 varieties of hardwoods, as well as on white pine, sugar pine, 

 yellow pine, cypress, California white and sugar pine, and ail 

 other soft woods. It has proven especially efficacious in the han- 

 dling of both red and sap gum, and white and red oak, as well 

 as majde, birch and other northern hardwoods. 



These preparators have an interior diameter of l()'(5".\17'lj". At 

 the back end is riveted a sheet steel dished head, and on the 

 front is secured a cast iron flange nearly 12 feet in diameter, to 

 which is fitted the Kraetzer patent .ioint, with a combined sheet 

 steel head and door. The shell is made of %" flange steel, in 

 :iccord:ince with manufacturers' standard specifieations. 



At the friint end of the shell a east iron ring it fitted, provided 

 with all necessary pipe flanges. On the interior at the bottom of 

 the shell are two steel rails running the full length of the cylinder, 

 usually with a four-foot gauge. The shell is designed for a work- 

 ing pressure of forty jiounds, and is provided with proper supports 

 running the entire length underneath the rails. The cylinder is 

 mounted on a concrete or brick foundation. On the front end of the 

 shell is fitted a flange which consists of a cast iron ring riveted to it. 

 The inside face of one-half of this ring is grooved, and fitted with an 



asbestos gasket, % im'h by I',-., inches. The other half is an exten- 

 sion flange fitting over a corresponding projection on the other half 

 of the shell. The door ring, which makes the steam-tight joint, 

 is made of cast iron without grooves. The door is guided at the 

 top by a wrought iron bracket, and is sujiported on two cast 

 steel brackets, provided with cast iron roller-bearing wheels, which 

 run on a section of steel rail, supported on a concrete foundation. 

 On one side of the door ring is fastened a east iron bracket, ami 

 on the door a lug, which is fitted with a swing eye-bolt and hand 

 wheel. This eye-bolt holds the door in its correct position on the 

 vertical joint. The door, which weighs about 12,000 pounds, can be 

 opened and closed by one man. The total weight of the apparatus 

 is 24,000 pounds. 



The quantity of steam required to load the cylinder two to 

 three times an hour is very moderate, anil usually lumber manu- 

 facturers have sufficient surplus steam in their boiler jilants to 

 suppl.v the necessary amount without the use of a supplemental 

 boiler. 



Further particulars covering the cost of the preparator, and the 

 necessary transfer and storage tracks, trucks, etc., can be secured 

 by addressing The Kraetzer Company, iiST South Dearborn street, 

 Chicago.
