PRACTICAL IDEAS ..here's the trading fifing and maintenance short cuts STSVfi KIONKA, Airoeioto fdilor Blow.er Ups Production, Saves Over $10,000 a Year Before iNStalunc ii for^d draft blower system on four 125-hp, hrt boil ers, seven men were neoded for o 24hour working day. That wbi to operate a sawmill of 80,000-board-feet capacity per shift. Three men worked eoch shift to slack wood slabs and hand-feed the wood furnaces. Seventh man banked end fed the fires' during the graveyard shift. In winter, under certain weather con ditions, because mill is in a narrow vai- luy, there wasn't enough draft to burn the wet redwood. Redwood has a ten dency to smother fires, causing lost pro duction. To help overcome this condition, we selected a tank for 300 lb of domestic hesvy fuel and piped it to each boiler. Then we Installed lines to carry steam to heat and blow fuel into furnace boxes. This system increased cost from 1800-1000 a mo, but did little good. Then f got the idea of putting in a forced-draft system. 1 used a 7yUj- electric motor from spares supply,W. ing and blower from an, Idle pkS. We bought dampers and eibowt (at targe 24-in. air-supply line. Cotton about $200. I installed e*eryihla|& about d0 days, during my iptm.tim at operating engineer.

M J Herzihc MUeca, Minn. n' ^ rtgvlotof Any kncinekr, who has had rubber hose age prematurely or from radiant heal, can profit from a simple idea we tried. Two boilers with both oil and 6as burners, aketeh, operated severs) months on gas fuel. One week after starting to burn oil, robber gas-burner hose was badly cracked and charred on side next to furnace. New hose were installed, but in several days (hero was noticeable burn ing. The hotter and more luminous oil flame impinged a beam ot radiant heal no bote, enough to burn it. Vfe wrapped hose with tin foil, held in place by a spiral of asbestos twine. This reflected heat so well thst tin foil aetuolly felt coot to the hand. Afier using it for more than a year we've had no further trouble from burning and charring. - J n MisKHHEiMKn Tulia, Okla. In July 1952, Piston Ring Manual, de vice can be improved to hold split pis ton rings white turning to true circle. Sketch shows clamping rig I mode for this purpose. Split ring is collapsed into clamp while nut is only light enough to keep ring from opening. Then nut is tightened. Since we make only.a few rings down here (away from supply houses) during overhauls, clamp need hold only one at a time.
