Text Appearing Before Image:
Fig. 12.—Sweets straight-line engine. The cross-head is shown in Fig. 15. It is of steel or malleable iron casting, and is threadedon the piston-rod and secured bv being split and clamped by the binding-bolts. The cross-head pin is a hollow steel castingmade fast to the connecting-rod, and turns in two adjustableBabbitt-lined boxes in the cross-head. The object of this is to secure lightness, extra wearingsurface, to prevent side swinging of the connecting-rod at the fly-wheel end, and to giveready means of oiling. The cross-head is what is known as the slipper-guide sort, the lowerguide being adjustable in the vertical direction. It rests upon and is bolted upon two mclinedplanes, and may be readily raised or lowered to bring the piston-rod in perfect alignment. 304 ENGINES, STEAM, STATIONARY KECIPROCATING.
Text Appearing After Image:
IlO. 22Fios. 13-22.—Dftuils of Sweets straif^lit-line engine. ENGINES, STEAM, STATIONARY RECIPEOCATING. 305 The crank-shaft and wheels are shown in Fig. 16. The steel crank-pin and shafts forcedinto the large bosses of the two wheels form a solid structure, dividing the strain equallybetween the bearings, and give an opportunity to balance the reciprocating parts properly,furnish a support for the governor, and relieve the main bearings of a good part of the thrustof the piston. The main journal-boxes are shown in Fig. 17. These sleeves. A, are made eccentric andlined with Babbitt-metal cheek-pieces B, which bring the shaft concentric with the outside ofthe shell. The cheek-pieces are retained in place by Babbitt-metal feather C at the bottom,and a brass wedge D at the top. This furnishes a complete bearing at the bottom and sides,and one in which the wear can be compensated for. Narrow metal liners are introduced atthe bottom, which can be removed and placed by the side of the wedg
