THERMOSTATIC CUT-OUT FOR ELECTRIC LIGHTING SYSTEMS.-This r~ent improvement combines with the main conductor of an electric lighting system a switch constructed and arranged to electrically connect the main conductor with the electric conductor of a huiiding. When, however, the temperature of the electric wires extending through the building exceeds a predetermined degree, the switch automatically shol~-circuits the current through the main conductor. This effect is accomplished by a wire connected to the switchlever and extending through the building, connected, or joined, at intervals by fusible joints or links. A wcight is provided for shifting the switch and short-circuiting the current upon the fusion of the joints or links. RAILWAY SNOW PLOW--A late invention comprises a ear or truck which carries two vertical and two horizontally-inclined endless aprons with supporting rollers, by which the snow is carried up and compressed, the upper horizontal apron being adjustable in inclination to regulate the amount of compression to whi5h the snow is submitted. All of the aprons are driven by rods and gear wheels from an engine, mounted upon the truck, and arc supported and adiusted by ropes and tackle from an upright frame on the car. The snow is divided and directed onto each of the aprons, and prevented from falling between them by an angle board above the adjoiifing ends. To the front of the ear is a funnel with its sides flanged to lap the mp and bottom plate. To the front of the funnel is a rceiproeating cutter-bar driven out by an angle-lever and crank-wheel from "the apron roller-gearing. INCANDESCENT ELECTtlICAL h m u m N A ' r m N . - - I n this improvement illuminated signals, symbols, designs, or figures are composed of electrical conductors bent or tbrmed into the required shape, and having numerous electrical vacuous cells removably attached or connected thereto.

These conductors have cavities or depressions therein, or grasping devices attached thereto, located opposite each other so as to hold incandescent electric lamps or vacuous cells ill ele(~ trical connection EI,EC~rRIc LAI~'TERN. This novel lantern is composed of wire frame-work of similar contour to the ordinary oil lantern. The upper part of the frame suppress a secondary battery, and an incandescent lamp is'supported directly below. Electrical connections for charging the battery, and similar connections between such battery and the lamp, are provided. There is a bail for carrying the lantern, and a removable top to give access to the batter.v. SToP-CocK.--In this improved cock or faucet an interior elastic flexible tube is provided, and an opening is cut away in the exterior metal tube to expose a portion of the flexible tube. A lever having a depending stirrup, arranged to compress the elastic, tube, is employed so as to stop the flow of the liquid. The lever, tbr this purpose, is eccentrically pivoted to a hand-operating lever, suitably journaled in bearings cast on the cock. RAH:WAY TRAIN TELEGRAPH.--This apparatus is designed for telegraphic communication between a number of moving trains and any number of intermediate stations. I t employs two suspended insulated main wires--one wire connected at one end with one terminal battery, and die other wire at its opposite end with another terminal battery--in combination with a traveling truck or sheave, connected electrically with the moving train, and in contact with the main wires, and havingjnleading and out]cading wires. The main wires are severed at the stations, and commcting wires from the severe
