Every turbine needs asbestos insulating blankets to conserve the power-giving h eat And be cause every turbine presents a special problem, every blanket is a custom-made Job- Even though the casttnfs on certain types of turbines are identical the pipes on the out side are made to suit the genera ting station where the turbine are to be installed. Mr. Shingler has to design the insulating blankets to fit these pipes. . His first step is to get the en- ' glneering drawings for each | new turbine.

A motor-driven cutter, 1 like that used In the cutting rooms of large clothing manu facturers, shears the heavy rock wool cloth into the weird shapes needed to fit the many curves of the turbine castings. Because different classes of turbines operate at different tem peratures, the type of asbestos blanket differs according to the temperature involved. Blankets of asbestos cloth are good up to 850 degrees.

They're actually two sheets of material with five-inch edges stitched to them. When a blanket Is Marly complete. It Is blown chock-full of glass wool. Sewing Isn 't Simple B la n k e ts like th e se a r e n 't stitched up on a gently-whir ring owing machine like mother uses. The turbine blankets are stitched with a thick cord made of asbestos wrapped around a heavy wire. The machine that does the sewing U much like that uatd by a shoemaker. Just as a mattress is quilted to keep the stuffing from shift ing or bunching, the asbestos blankets are tufted with steel wire and washer*. ( Some of these tufting `'but tons" have hooks on them, Uke the hook of * hook-and-eye. When the blanket is placed in position, wire Is laced back and forth between the hooks to hold the sections together. Modem design has stream* lined the turbines with sleek < outer covers of m etal so the customer rarely aces the fine handicraft of Clamance Shlngter and his associates. But be cause their Job is done to such exactness, the customer has more reasons to be sure his new turbine will operate efficiently-
