LUMINOUS PAINT.Not U«cd for Keyholes—Of Value onClocks and in Powder Mncazinei.“No, said a dealer in paints iu response to an inquiry on the subject, “luminous paint would not afford a cheap, simple aud easy solution of the street corner sign problem aud furnish signs that could be read easily by night as by day. because there is too much light everywhere at night in the city to permit such signs to show plainly.“Paint a sign of luminous paint at the entrance to a dark alley and you would tiud that it could be plainly seen, as would be the case also with a doctor's sign painted in a shadow or a house number iu a similarly protected situation. Luminous paint is used to paint stones marking tbe entrnuce to drives, aud it is put to various other uses.“Used for painting keyholes? No. I can’t say that it is. It hus been suggested that in this use an urea or a foot square should be painted on the door, with the keyhole at the center. The man trying to find the keyhole would certainly get within that foot-square area without difficulty to start with, ami once there, he would work naturally toward the center. Hut, seriously, while 1 don’t know of any reason why it shouldn't be I have never heard of luiiiiuous paints being used on keyhole plates. A simple use for luminous paint is on match boxes, which are thus made visible and easy to find night. Thousands of clock faces havY\ been painted with luminous paint, and proper sort of contrivance painted wifti it can be made to serve as a lantern.“A while ago we had a call from a powder manufacturer, who wanted to know if we could fresco the interior of a powder magazine in such a way as to make it light enough there so that they could read the* marks on the powder barrels. We could scarcely do that for him. but we could supply him with something that would serve the same end. which we did.Cardboard Is treated in such a manner with luminous paint as to make it suitable for a background for signs, and of luminous cardboard we made a simple light giver by means of which the marks on the barrels could be read. This was a suitably mounted or framed sheet of the cardboard, a foot or thereabouts square with a handle on one side; something like a framed picture, with a handle attached to it.This is kept hanging in the otllce in the light, and when required for use it is simply carried into the magazine and held over the barrels to read the markings by in getting out the packages they want. You couldn’t read the fine print in a newspaper ‘by such a light, but you onn read readily by. it the markings it was designed to reveal: the powder concern sent for a dozen more of these cardboard illuminators right away.“Obviously such a means of shedding light could be used iu cellars and so on anywhere, in tLie city or out of it.’*—New York Sun.
