Locomotive appliances . aribbon of paper, having thereon horizontal and per-pendicular lines, each horizontal line from the base orzero line representing five miles per hour, and eachperpendicular line a mile post along the road. If the locomotive is moving at the rate of twentymiles per hour the pencil will trace its mark on thefourth line from the base or zero; and for every miletraveled the paper will move under the pencil one-halfinch, or the exact distance from one perpendicularline to another. By examining the chart, the exact speed at whichthe train passed any point on the road, the numberand location of stops, the distance, speed and locationof any backward movement that may have beenmade, can be determined at a glance. In the cab of the locomotive, in view o( the engineer, 408 LOCOMOTIVE APPLIANCES. is placed a gauge similar in appearance to a steamgauge, the needle of which points to the number ofmiles per hour the locomotive is moving. This isconnected to the piston of the machine by a small wire. Fjg. Railway Speed Recorder. enclosed in a one-eighth inch gas pipe.
