Rail′way-sweep′er.
(Street-Railway Engineer- [1871] ing.) Stationary splint-brooms at the fore part of the engine are commonly used for clearing small obstructions from the track. Rotary brushes are also used. Fig. 4141 is of this kind. It is fixed on a diagonal shaft and rotated by gear connection with the axle. By means of the screw Q, levers L M, and connecting-rods R S, it may be lifted out of gear and clear of the track when desired. Fig. 4142 is a plan view, which shows the relation of the brush-cylinders to the bed and the wheels. The brushes are revolved by gearing on their shafts and on the wheel-axles, or by belt and pulleys; are adjustable vertically; may be preceded by oblique and vertically adjustable scrapers; set obliquely to clear the horse-track, or revolve in line with the rail to clear the wheel-track.
