Of side-cut devices, the rotary cutter is per-haps the most simple in construction, and themost reliable in operation. Its action is entirelyautomatic and extremely sensitive to regula-tion. It produces bricks of uniform thicknessand smooth angles. Being independent of re-ciprocating action, the cutter may be run atany desired speed, and as the wires always movedownwards and forwards, making an angle withthe top surface and outer edge of the bar, allobstructions are pushed from the surface intothe body of the bar, thus preventing the rufflededges common to many side-cut bricks. In the machine shown in Fig. 3, the pair ofbevel gears (a) are encased in a dirt tight casewhen the machine is in operation. These gearstogether with the measuring wheel situated im-mediately under the bar of clay, forms the con-.

The bar ofclay is supported on the bottom face and at oneside thus ensuring a smooth sharp cut. Theslit .through which the wire passes is just wideenough to accommodate the thickness of thewire used. The two vertical side-plates (b)are hinged so that they will open outward if astone or other hard substance is pushed againstthem by the cutting wire, and after expellingthe same return instantly to the normal positionof support.
