. Railway and Locomotive Engineering . May, 1913. RAILWAY AND LOCOMOTIVE ENGINEERING 163 General Correspondence Portable Jig for Use in Applying Con-vex Headlight Protector : Convex protector glasses used inconnection with arc houses of loco-motives equipped with the electricheadlight present a most difficult andtedious piece of work in applying themto the door-rim when the same is at-tached to the house, in many caseshigh upon the engine. This diflicultyarises because of the numerous strips, expander and holderrings that are a part of the methodused to hold the glass in place. In case the rim is removed from tlichouse and laid upon a bench, the con-vex shape of tlie glass still presents afeature that is annoying because ofthe construction of the rim, in mostcases built to allow the glass to dropdown into it. Fig. 1 is a sketch of a light and port-able stand that will alleviate everydifficulty experienced while workingwith these glasses because of theirconvexity and the construction of The door rim drops down into tlieband of the stand which securely liol(l>it. The small legs keep the point ofconvexity on the glass from toueliini;the floor or bench and also allowsenough space for placing the liandunder it to shift the glass while apply- iiiK the \ibiulion strips, lugs, the rim held in this manner, theapplication of one of these glassestakes up but a very small amount oftime, and at the same time the deviceeliminates all danger of breakage tothe expensive convex glasses. 1.
