- MOLD FOR GLASSWARE.

SPECIFICATION forming part of Reissued Letters. Patent No. 9,904, dated October 18, 1861,

1 Original No. 145L629, dated October 14. 1813. Application for reissue filed August 5, 1881.

['0 all whom it may concern:

Be it known that I, GEORGE E. DOM-AX, of Somerville, of the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Glassware-Molds, 850.; and I do hereby declare the same to be described in the following specification, reference being had to the accompanying draw ings, of which- I FigureIis atop view ofall ofa mold or apparat'u's of my invention except the press-plunger, to be described. Fig. 2 is a front elevation, and Fig. 3 a vertical section, of such apparatus with its press-plunger.

The object of my invention is to mold a-handie and apply it to what is termed by glass- "rare-makers a blow-over article; also, to blow the said article in a mold and form andapply or affix a handle to the said article while it is in the mold; and my invention consists, in part, in the combination 'of a handlematrix and a press, essentially as hereinafter described, with a mold or device for holding against the said matrix the glassarticle, so that molten glass may he forced into the matrix and against the glass article and become connecteddheretn and constitute a handle therefor.

In using my apparatus the articlc of glass ware may be molded or formed in the mold, and subsequently have the handle applied to it.

In the drawings, A A denote the twohalves or mainparts of the mold, they being hinged togetlier and mounted upon a base, I, in the ordinary manner.

C C are handles extending from such parts A A, and for aiding in opening and closing them.

D represents one hnlfofthe matrix Forforming the body of thearticle, the other half corresponding with suchpart l), with the exception of the gates thereof.

Within the shell of the mold is the handleforming matrix E, one half of such matrix be ihg formed in each half of the mold,a1rd,open- .ing into the main matrix by two mouths, a a, provided, respectively, with gates G G, by which communication between the handle-matrix and the body-matrix ma y be cut 911' as oocasion may require. These gates extend transversely through one half of the mold, and are connected to anupright bar, H, which, by

'pressed through the passage b into the handleformiug matrix, in order to fill such and form a handle and cause the endsof such handle to so impinge against the heated glass article in the body-matrix as to be firmly afiixed to it, (the said article.) This employment of the presser or plunger insures not only the formation of the handle, but a strong and positive fixation of it s to the body portion of the articleof glassware.

Having described the mechanism for forming'a glass article and its handle and fixing them to each other, the method or process of using such i; as follows: The gates G G are first to be closed, in order to interrupt commu: nicaiion between the body matrix and the bandle-matrix. The glass-blower having collected on the end of his rod or blow-pipe a suflicient quantity of molten glass to form the body of the article, and having manipulated and treated it in the ordinary manner, places it in the body-matrix and closes together the several parts of the mold. This having been efi'ected,

he next inflates the glass, so asto cause it tofill the bod y-matrix and form therein the body portion of the article. Having done this, he' opens the gates and pou rs into the font or presschambers. sufiicie'nt quantity of glass in a molten state to form the handle of the article,

and he puts the plunger'into the press-chamher and forces the glass'thereof into the bandle-forming matrix, the end portions of the handle being by such firmly pressed into contact with the outer surface of the article in the body-matrix, a strong union of the handle and body being thus produced.

Having thus described my invention, what I claim as such is as follows, viz:

'1. The combination of the handle-forming matrix, and its press, with a device for holding or supporting against tbesaid matrix avessel or article of glassware, while ahandle is being formed, in the said matrix and against the said vessel or article, by means of the matrix and the press, substantially as set forth.

2. The combination of the handle-matrix, and its gates and press, with a device for holding or supporting against the matrix a vesseLor article of glassware while a handle is being formed, in the matrix and against the said vessel or article, by means of the matrix and the 10 press. substantially as set forth.

3. The process of molding a handle of glass, and fixing it to an article of glassware, such consisting in confining the article in a holder or mold, andagaiust a handle-forming matrix, and by means of a press, as described, forcing glass, in a molten state, into the said matrix, and against the glass article held thereto, all

' being substantially as set forth.

4; Blowing a vessel or article of glassware 20 in and forming it by a mold and by means of a handle-matrix, and a press, as set forth, and while the said article is in a sufllclently-heated state-,moldingahandh from molten glass,with-' in said matrix, and forcing such handle therein, againsttne blown and heated article in the mold, so as to cause the handle and article of glass to combine with or to be connected to each other, as described.

5. The combination of'thehandle-forming matrix, and its press, with a mold for molding, in manner as described, the body of an article of glassware, and holding it against the handleforming matrix, in order that arhandle, while being made in such matrix, may be forced into contact with and united to the said body, all being substantially as set forth.
