' The operation of producingtne lamps with handles vupon them vissagis follows: jWe first close the tivo .halves for jing the loiver section 'of' the molde'ndintroduce het gloss into the matrix g g', whichigla'ss wiiLfloi'v vto thehin-v t'om of themetrix.

The mold is then opened and the nished lamp taken out-fol" n ..repetition ot the process.
The handle J, Whitt4 is me `first thingpmduced, is cast in the vmatrix 'made for, it by dropping or inserting a. piece of ht glass in rsaid matrix, so that the lglass willfbe more or' less exposed beyond the lower opening of this matrix, then cutting 0E e. s 'ufi'cient length of the piece of glass above the matrix to form the upper part of the handle`,which pieeeis pressed over so as tollie into thenpper portion ofthe vmatrix with its end depressed. .This forms the yhandle completealnd ready to' be attached to` 'thebody'of the lamp or'other-article, as above described, and obvietes the objections und labor required to produce glass handles by. hand, as hitherto practiced in themnufectnre of'blown glassware. f
Having described our invention, what we claim as'new, and desire to secure by Letters l. Producing'handles vforgless lamps and other glassware by castingthem in l'nolds ready t0 be attached to such articles, substantially as described.

of attaching glass 'liandles'to lamps or other'` artielesof .glass in the process of blowing's'nch;

4.' Dropping h'ct flexible glass into y a mold for the purpose of forming ahandle-or handles for the bowl' of a-lani p or other vessel.
