MANUFACTURE OF GLASS JEWELS.
SPECIFICATION forming part of Letters Patent No. 309,381. dated June 17, 1884'.
Application tiled March 2Q. 1884.
To (LZZ whom it may concern.-
Be it known that I, HENRY O. LUTHER, of Providence, in the State of Rhode Island, have invented an Improvement in the Manufacture of Glass Jewels, of which the following is a specification.
The nature of my invention consists in the improved construction of the dies and tongs for pressing the jewels, and for holding the same while cooling, or for fire-iinishing, as hereinafter set forth.
Figure 1 is a vertical section of the press employed for pressing the jewels from melted glass. Fi 2 is a detail view showing a front elevation of the die-holder and a vertical section of the lower portion of the die and the jewel-lifting tongs. Fig. 3 is a detail view showing the upper and lower dies as closed upon each other to form a jewel. Fig. et-is an edge elevation of a jewel. Fig. 5 shows a plan. View of the tongs for removing the jewel from the die. Fig. 6 represents a section taken in the line :0 5c of Fig. 5. r
In the accompanying drawings, A is the frame of the press; B, the sliding head, which serves to carry the upper die, 0. The lower die is made in two .parts, of which D is the fixed exterior, and E the movable interior, portion, which is operated up and down in timely relation to the np-aud-down movement of the die C by means of the pivoted lever F and rod G, which connects at its lower end with a treadlc. The inner portion, E, of the die is made to rise from the outer portion, D, by means of the pin a, secured to the connectingbar G, which serves to elevate the portion E upon the arrival of the die 0 at its upper limit of movement, as shown in Fig. 1. The tongs H, for removing the jewel I from the die E, are provided with the two jaws Z I), having a groove, 0, adapted to receive the edge of the jewel, as shown in Fig. 6.
In the manufacture of the glass jewels, the heated end of the glass rod is to be placed between the upper and lower dies. Then a sudden downward movement imparted to the die C will bring the dies together, with the heated glass between them, as shown in Fig. 3, and
. {No model.)
upon the upward movement of the sliding head B the inner portion, E, of the lower die will be raised by means of the pin a, as shown in Fig. 1, from which position the projecting edge of the jewel may be inelosed by the groove 0 of the jaws Z) Z of the tongs, as shown in Fi 2, and then removed from the die E, either for the purpose of cooling the glass jewel or for fire-finishing the surface of the same.
Heretofore in the manulacture of such glass jewels the jewel, after being formed in the dies, has been still retained attached to the glass rod, and as the jewel requires a considerable length of time to cool to the required degree of hardness to bear handling and contact with its fellows, the glass bar from which the jewels are to be formed will be keptfrom the furnace for a long time, thus entailing a loss of heat; whereas with my improvement the glass bar may be removed to the furnace upon the instant of the closing of the dies, and while the bar is being held in the furnace and manipulated by the left hand of the operator the tongs held in the right hand may be used to remove the jewel, and to hold it while cooling or while the same is being lire-polished. Thus the heat of the furnace may be utilized to a greater degree than heretofore, and a greater number of jewels may be turned out by the operator in a given time.
The jaws Z) Z) of the tongs are intended to I hold the jewel loosely, so as not to distort the same when removed from the die while in a highly plastic condition.
I claim as my invention The improvement in the manufacture of glass jewels, which consists in the combination of the upper die and the lower die, made in two parts, and means for operating the same, substantially as described, with the tongs provided with the groovcdj aws adapted to remove the jewel in a plastic condition from the elevated inner portion of the lower die without danger of distortion, substan tially as described.
