IMPROVEMENT CAST-METAAL LAMPS.

Specification forming part of Letters Patent No. 100,39, dated March 1, ISQ.. .N, l

Be it known that I, T. F. HAMMER, of Branford, in thecounty ot',` New Haven and State of Connecticut, have invented a nersT Improvement in CastfMetal Lamps; and I do hereby letters of reference marked thereon, to be a and which said drawings constitute part of this speciticatioma'nd represent, inl Figure l, a side view ot' the casting; Fig. 2, a side -vieW turned one-fourth around from Fig. l; Fig. 3,-a vertical central section in of Fig. 2; Fig. 5, the lamp complete, and in Fig. 6 a {sectionof the body of a hangin glamp constructedi in like manner. f

This invention is designed for lamps for the use of manufacturers where they are liable to forother purposes.; and the invention con sists, first, in forming the body from cast metal, so as to form the neck and filling-tube all in the same pieceand at the same operation 5 also, in forming upon the body, during means of securing the handle to the lamp, or

as a means of suspending the lamp.

A is the body ot' the lamp; B, the lling tube; the body Aformed with a neck, C, and

cast from metal, by molding in the usual manner, the neck und filling-tube being formed,

PATENT OEEQICE. f

so thatthey maybe tapped (lut and fitted l i l l with caps, as seen in Fig. 5. I'prefer to cast these lamps from iron made ma leable, as less liable to breakage or injury thanany other cheap metal. l e

In hanging lamps the casti g is madein substantially the same` manner with the iill` i ing-tube and Wick-neck in abouttlresame'rel-W ative position as in Fig. 7 The form of the lamp is immaterial, though for hand'lamps the shape shown in Figs. l and 2 is believed to be the mostdesirable.

To hand-lampsit is necessary that the handle D be attached, as seen in Fig. 6. To this end I form, in the process of casting, studs u j upon the bodynof.ithelamp,.upmyliiclljthemng handle isplaced, (being previously perforated 1 i, accordingly,) then the' studs riveted down g onto the hjandle, as seen inFig. A j l I claim my invention- 1. A cast-metal lamp consisting ofthe body A, tube B; and projections a, all in one and the same piece, and produced at the same opt' eration of 2. In cast-metal lamps, the projections a a, cast and formed upon `the body during the process ot' casting, substantially in the manner and for the'purpose specified.
