IMPROVEMENT IN THE MANUFACTURE OF GLASSWARE.

Specification forming part of Letters Patent No. 163,787, dated May 25, 1875; application filed April 19, 1875.

' of this specification, in which, like letters indicatin g like parts- Figure l is a view in perspective of a glass vdish having claw-shaped feet pressed thereon.

Fig. 2 is a top or plan view of one form of mold in which such article is made. Fig. 3 is a sectional view thereof in the line x w, Fig. 2. Fig. 4 is an inverted or bottom view thereof, and Fig. 5 is a plan sectional view as formed by a horizontal plane passing through the mold on a level with the upper face of the movable side sections.

In a separate application filed by myself and August Sperber, February 27, 1875, we described and claimed one construction of mold suitable for making a bowled article of glassware with feet pressed thereon at the same operation, such feet having an inward or re-entrant cunve on their outer sides or edges, or being, as I now for convenience designate them, claw-shaped.

,My present improvement relates to the article thus made, that being my own invention, and to another construction of mold for making the same.

The mold shown in the drawing consists of an unjointed part, B, for the pressing of the bowl therein, and which part may be either made as a part of, aixed to, or arranged on a base part, B. This base part B has a neck, b, in the outer periphery of which are the leg or foot cavities a, which latter communicate with the bowl-cavity above, and below'the neck b the base B flares outwardly, as atb', so as to form a bottom to the footcavities a, and also a base for the hinged sections D.

These hinged sections D encompass the neck b; but such parts of them as come opposite to the foot-cavities a are so formed, as at d, as to close up the foot-cavities a on the outer sides or edges thereof, and' thus make the cavities complete for the pressing of the feet a therein; but also these faces d are shaped so as, when in position for pressing, to form each a re-entrant part, extending inwardly beyond the extremetip of the foot a', or end of the cavity a, as illustrated in Fig. 3. Thus, in the foot a', as pressed therein, I get on the outer side or edge of it an inward curve.

The sections D are hinged together, as shown in Fig. 5, so they may be brought up and closed onto the neck b while the pressing is being done, and also so that, in order that the article, when pressed, may be re moved from the mold, they may be thrown back until the parts d are beyond the tips of the feet a.

To this end two of the sections should receive iirst an outward motion, in which they will be guided by stems c affixed thereto, and playing in slots e in the base-ange b', and then all may receive a backward motion by the stems c c c passing along the slots e; but other modes of giving these sections D an 0utward-or backward horizontal motion may be employed; nor is it essential that they should be hinged one to another.

The mode of pressing will be readily understood by those skilled in the art.

This construction of mold gives a iinless body or bowl, A, the only iin produced being along the joint formed by the re-entrant part d and the edges of the cavity a; and such fin, by a bead or otherwise, may be so perfectly concealed as not to be objectionable. In this manner I produce a bowl, A, having a Iinless or seamless body, and pressed claw-shaped feet made thereon at the same time and in the same operation.

The same mode of manufacture may be employed in the production of footed articles of hollow glassware generally.

I claim as my invention- 1. As a new article ,of manufacture, aprcssed iinless or seamless hollow article of glassware having claw-feet pressed thereon, substantially as set forth.

2. The combination of hollow mold B, hav- In testimony whereof I have hereunto set ing a cavity of any desired form for pressing my hand.' the body of the article to be made, a base, b, in which are the foot-cavities a, and movable sections D, having re-entrant faces d, .and Witnesses: moving in horizontal planes7 substantially as J AMES M. CHRISTY, set forth. GEORGE H. GHRIsTY.
