In the construction of this lamp I do not claim the invention of any new material of which the lamp is inade, nor the mode of using the locket and wick tube by inserting it into a cup of oil; but what I do claim as my invention, and wish to secure by letters patent, is the peculiar form which I give to the lamp cup: that is, by depressing the top of the lamp cup where the wick tubes are inserted downwards in such a manner as to elevate the sides of the cup some one or more inches above the top of the wick tube, and thereby surrounding the flame of the lamp with a transparent shield; for, when a lamp cup is depressed in the centre in this manner, it forms a hollow rim around the sides and top of the lamp, which is intended as a protection against the numerous accidents occurring every day by oversetting of lamps and spilling the oil, or setting on fire articles coming into contact with it, when overset. In this lamp, instead of the oil, when overset, running out at the vent holes, or the top, (or the socket, should it fall out,) the oil runs into the sides, which, being

Y large enough to hold all the oil, prevents any spilling, and at the same time surrounding the flame. T. F. STRONG.
