`WASHINGTON BECK, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN GLASS-MOLDS.
Specification forming part of Letters Patent No. 180,450, dated August 1, 1876; application led June 23, 1576.
To all whom fit may concern:
Be it known that I, WASHINGTON BECK, of Pittsburg, county ot' Allegheny, State of Pen nsylvania, have invented or discovered a new and useful Improvement i-n Glass Molds and Bowls; and I do hereby declare the following` to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawing, making a part of this speciication, in which like letters indicate like parts.
Figure 1 is a vertical sectional view of my improved mold, and of a glass bowl pressed therein, with the plunger in elevation. Fig. 2 is a like view of the mold inverted for the discharge ot' the bowl; and Fig. 3 illustrates the product of the operation involved.
My improvement relates, chiefly, to the manufacture ot' hollow pressed glassware,wherein a ligure, out, monogram, or other design, is to be pressed or imprinted on the outer side or vertical wall or walls of the article to be made. For this purpose I make the design on the end of a die, and operate the latter through the sides of the mold, toward and from the axial line of the bowl-cavity, so that when forced in the die-face shall constitute a part of the cavity-wall, against which the molten glass is to be pressed, and so that, with a backward or reverse stroke of such die, it will clear the glass article, and oiier no impediment to the removal of the latter from the mold.
Myimprovement can be used with any kind A of mold ordinarily employed in pressing articles I make use of a movable die, c, which plays loosely in a suitable hole in the side wall of the mold. rllhis die e has on its inner face a 4representation or counterpart of the design to be pressed or imprinted into or onto the glass, and it is so arranged that while the pressing The usual ring-plate d is employed, as
is being done its inner end shall constitute a part of the wall or faceof the cavity, and so that after the article is pressed it may be shifted back out of the way of the discharge of the article from the mold. To this end I make the die c with a rear extension, c1, which projects outside the mold, and has a hole, e2, therein. In convenient proximity thereto I pivot on the side of the mold a bent lever, s, preferably weighted, and with the weight s so arranged, by preference, that when the mold is in position for pressing, the lever s, passing through the hole c2, will, under the action of the weight, force the die e forward to the pressing position. rlhis position is fixed by means ot' a stop, i, inserted at the proper point. These parts are so shaped that the ringplate d will engage the outwardly-bent arm of the lever, and prevent the pressure of the glass on the end of the die e from forcing such die backward while the pressing is being done, which latter is done in the usual way. When the plunger and ring-plate are removed, the mold is inverted, and the weight s then operates to throw the die c back out of engagement or contact with the glass article c, as illustrated in Fig. 2. The weight of the movable bottom, or a slight jar, or both, will then suffice to effect the discharge of the glass article from the mold, with the desired design pressed on,- or in the outer face of its vertical wall.
For the purpose of holding the die e forward while the pressing is being done, the bent lever may be so shaped as to be engaged bythe spring-plate of the press, or by the foot-mold or bed-plate, as the mechanical equivalents of the construction described and shown, andthe mode of effecting such arrangements of bent lever and moving die, so that the latter shall move through the lateral Walls of a mold toward and from the axial line ofthe mold-cav ity, in combination with asuitable stop at the limit of forward motion, will be readily understood by those skilled in the art.
The die c may be duplicated at one or more points around the mold.
I thus produce a inless or seamless bowl or cup-shaped article of' glassware, having the l name, monogram, or other proprietary mark of the owner thereon. Such an article is shown in Fig. 3. By the addition ot' an ordinary footmold, nless or seamless goblets having sueh proprietarymark may be produced by the operation described.
The mode of making other hollow bowlshaped nless articles of glassware with such mark thereon will be understood by the skilled Workman.
I claim herein as my inventionl. In combination with a glass-mold and a moving' die passing through its side Walls toward and from the axial lille of its cavity, a Weighted bent lever to effect the movement of the die, and a suitable stop to limit its inward motion, substantially as and for the purposes set forth.
WASHINGTON BECK.
