IMPROVEMENT IN (irliA'SS-lldOULDS.A

TO ALL WHOM IT4 MAY CONCEll-N:

Bo it known that I, DAVID TURPIE, of Sandwich, in the county of Barnstable, and StateV of Massachusetts, have invented an Improvement in Moulds forForning Glassware with Ilandles; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suilicient to enable those skilled in the art to practise, it.

Moulded articles of glassware having handleshave heretofore shown on the outer surface from rim to base at leasttwc vertical seams, occasioned by vertical joints in the moulds, at'the parts where the casing separates to discharge or free the moulded handle,'and the object of my invention is to mould articles of glassware with handles, (likebeer-mugs for examplc,) without seams continuing them from the top or rim to the base of the glass.

In moulding or pressing handled mugs, 85e., the mould has heretofore been composed ofthe following principal parts-a base, an outer vertical shell, in two or more parts, having in one joint thereof the part of the mould in which the handle is formed, a plunger, and a. top-piece, which forms the rim of the glass, and guides the plunger. -i I' New, my invention consists in adding to said parts a hollow slotted cylinder, and certa-in pieces which are attached to the outer shell, 'and extend into the 'slot in the hollow cylinder, and nearly through itI In the old arrangement, the outer vertical shell formed the outer cylindrical 'surface of the glassware, as well as thcvwhole of the handle. In my arrangement, a part only ofv the 'handle is formed in the Outer vertical shell, and all of the outer upright surface of thebody of the glass article is formed by the inner surface of th slotted cylinder. Of the drawings which represent a glass-mould, embodying my inventionl' f Figure 1 is a vertical central section, taken-in the plane of line z z, seen in Figure 2, which is a plan of the mould with the top-piece and plunger removed.l

Figure 8 is a horizontal section of a part of the mould, taken on the line y y seen in fig. 1.

a denotes the plunger, which forms the cavity or interior of the moulded article 6. c is the top-piece, which guides the plunger and forms the top edge of I). d is the outer vertical shell, which is made in halves, and is hinged and held together 4by lapin/and ears in the usual. manner. e is the base, which is locked in the outer caso in the usual manner.A fis the slotted cylinder, which forms the outer part of the body of b, and a portion of the handle, thebore off being somewhat taper, so Vthat said cylinder can be lifted oiffrom the glass with ease,

by means of the handles g, which are let into Yslots formed in d, and by which the relative position of the slot infis determined with regard to so much of the handle-mould as is formed in ol. On eachside of the joint in d, onthc side of the pin It, are secured pieces z' and y', said .pieces entering and lling a portion of. the slot inf, and the vertical joint of the outer case continuing throughthe vertical-central plane of said pieces. The piece zforms the part ofthe surface of themould which makes the inside of the handle, and the piecej forms a part which makes a portion ofthe lower outer surface of the handle, and the inner surfaces of the' pieces and j aremade so as to form flat surfaces or faces, or a kind of panel on the surface o'f the body of b, within and beneath the handle. f

Now, when the outer part, d, of the mould is closed upon the'base-piece e, and is-secured by the pin k, the slotted cylinderfis pushed into its place, the slot therein sliding down over the pieces z' and j, and the handles g entering the slots in the casing d; then the top, c, is applied, andthe plunger a is forced, bythe action of a press, down upon the molten glass, which has been previously deposited in the mould. The action ofthe plunger displaces the molten glass, -causing it toll all the vacant space in the m'ould,pressing into the channel which forms the handle. Theplunger being then withdrawn, the top-piece is removed, and the slotted cylinderfis lifted out of the mould off from the glass, and the pin 7L being withdrawn, the two parts of the outer casing cl are swung open, and the moulded glass is left standing on the base, e, from which it is then lifted oli'.l

It will be seen that by the described construction ofthe mould, but one seam orjoint line is shown on the article, said scam extending along the centreof the handle to the base of the mug, but not from the top of the handle to the top of the mug. Of coursethe inner surface of the slotted cylindcrf may be formed so as to mould uted as well as Yplain ware.

I claim a glass-mould, constructed and arranged to operate substantially as and for the purpose described.

DAVID TURPIE.
