Abstract
1,078,505. Grinding. F. C. LEONARD. June 20, 1966 [June 29, 1965], No. 27471/65. Heading B3D. [Also in Division B5] A mechanical saw, which may have a toothed or abrasive blade, comprises means for continuously determining the length of that portion or portions of the cutting edge of the blade which is in contact with a workpiece at any instant during a cutting operation and means responsive to the determining means for varying the loading applied to the saw blade such that the load is at all times proportional to the contact length. The determining means may comprise a pipe 10 having a slot or number of jets directed towards a copy 11 of the cross-section of the workpiece to be cut, the pipe, at one end, being connected to an inlet pipe 12 and restriction 13, and, at the other end, to an outlet pipe 14 which includes a restriction 15 and is connected to a cylinder-and-piston device 16, 17 adapted to apply a loading to the blade of the machine, the pipe moving over the copy in correspondence with the movement of the blade through the workpiece. The copy may be of metal or wood or be formed from an assembly of small rods mounted in an open-ended box, the assembly being pressed against the end of the workpieoe to displace the rods engaged by the workpiece and thus form a replica of the workpiece. In another embodiment which does not use a copy of the workpiece, a twin blade assembly is used to cut the workpiece, the blades being spaced apart by a small distance and sealed by a packing piece at their back edges and ends to form a manifold. Air or liquid, such as coolant, is supplied to the assembly which is also connected to the loadapplying device of the machine. As the blade moves in contact with the work, the latter acts on the space between the blades to vary the flow of fluid therethrough and consequently the pressure of fluid supplied to the loadapplying device.
