Show I ENGINES RUN ON SNOW. H NEW LOCOMOTIVE BUILT FOR M NORTHERN PINERIES. H Mounted on Sleds, the Machine Hauls H Great Loads of Logs Has Novel H Traction Device Speed of H Five Miles an Hour. H Minneapolis, Minn, A now nml H iowcrfiil snow locomotlvo for i.o In H InrRO part In hauling logs In thu H iilncrlcs of northern Minnesota, Wis- H L-onsIn and other northwestern states V' hali been built nud put Into service. H A portablo hollar, firebox pattern, Is H mounted on a heavy channel Iron H frnmo which extends from the extremo H front to the- rear or the machine. The H channels support the cab and tho coal H tender. A water tank Is carried under H tlio boiler on thn name frame. The H latter In turn Is supported by thu H heavy traction wheels In tho rear and H by tlio sled In front. Tho boiler Is ton H feet In length, 35 Inches In diameter, H tubes Hi Inches. H Four cylinders are provided for H transmitting power. Those aro at H (ached In pairs, two ermines on each H side of the bollor, bolted to tho frnmo H and boiler In nn uurlght position. H Kacli pair of engines la equipped with H reversInK link motion. H Tho traction device consists nf two H heavy runners, one on either Bldo of H Die eiiglno, which aro carried on u GV4- HH Inch Iron shaft. On each end of theso f runno's Is attached a pair of heavy fcj boxes In which Iron shafts run. Koch fl shaft has a heavy sprocket wheel and H these wheels mesh Into and carry tho H tread on log chains, Tlio latter aro Hj 12 Inches wide and nbout 2$ feet long. H Kach pair of runners also has two H tool-stool roller chains. Theso chains H are shown on tho sides of tho sprock- H ets under tho tread chain. This trac- Hj tlon dovico Is novel and certainly the H most Interesting purt of this locoino- H When tho engines aro started power Is truusuiltted by spur pinions on crank shafts to pinions on tho fiont end of tho drlvliiK shafts. On tho tear end of these liilng shafts uro attached at-tached bovel pinions which inesh In lai'KO hovel Keurx miming on millls on tho iiinlu bearing. Theso hovels also have a spur fiear nttnehed to Iheni which rarrles tho power through nn Intermediate gear and another spur gear to tlio shaft of tho rear sprockets, tho tear being the driven sp'rocket. All Rearing Is cut from solid steel. Tho runner eastings, sprockets, tri'ad chains jind ull'parts subject to severe strain nro niado from a high grade of cast stcol and aro built for sovero woik. Tho cab Is titled up In tho usual locomotlvo lo-comotlvo stylo, each engine having quadrant and level for tovorslng. Tho regulnr typo of locomotlvo throttle Is used. Theso engines weigh about 10 tons without coal or water and about 18 tons when ready for tho load. With 200 poundB of steam pressure thoy do-vclop do-vclop about 100 horsepower aud luivo a speed of from four to.flvo miles an hour. When tho roads aro well graded and Iced theso engines will handlo from soven to ten heavy logging sleds. Sov cral engines hauled 00,000 feet ot green hemlock and hard wood to the loud aud niado three round trips ovory ten hours on an elght-mllo road, or CO miles a day. Tho bulldor of theso snow locomotives, locomo-tives, ii manufacturing company of Knu Claire, Wis., has dollvored several of them to lumber llrms. principally In Minnesota nml Wisconsin, and successful suc-cessful records wero niado. Ono on glno near Walker, Minn., took nine sleds to the lundlng, each slod carry Ing 12,000 feet of whlto plno nud Nor way logs, and ono made four trips on a llvo-mllo road ovory day. This engine Is particularly serviceable whon tho timber Is scattorod or stands In small bodies |
