Abstract
619,461. Sawing stone. R.I.T. REALIZZAZIONI INDUSTRIALI TECHNICHE S.R.L. Dec. 11, 1946, No. 36631. Convention date, Dec. 22, 1945. [Class 124] In a multi-bladed stone-sawing machine all points of each blade describe closed trajectories comprising substantially rectilinear lower portions for the sawing strokes merging at both ends into curved upper portions for the return strokes. As shown, one cross-head ? h of the blade-carrying frame rests on counter rollers m carried by main rollers i, whilst the other crosshead e is pivotally connected to intermediate points c of connecting rods ab, a<SP>1</SP>b<SP>1</SP>, the ends a, a<SP>1</SP> being rotated about fixed points o, whilst the ends b, b<SP>1</SP> are pivotally connected to cranks oscillating about fixed points d. The driving shaft for the ends a, a<SP>1</SP> may carry a pair of fly-wheels s; s<SP>1</SP>. The side members of the frame are also connected by a pair of bladetensioning members f, g, and the frame is supported by three screws v<SP>1</SP>, v<SP>2</SP>, v<SP>3</SP>.
