TILE PRE SS-MOLD.

To all whom. it may concern:

Be it known that I, WILLIAM PAssMoRE MEEKER, a citizen of the United States and of the State of New Jersey, residing at Ma plewood, Essex county, New Jersey, have invented certain new and useful Improvements in Tile Press-Molds, of which the following is a specification.

l\-Iy invention relates to that class of pressmol-ds which are designed to form glass tiles with undercut lugs or projections thereupon, and consists in the particulars hereinafter set forth.

The drawings illustrate the following parts of my improved press-mold.

Figure l is an end view and Fig. 2 is a side view of the plun er; Fig. 3 is an end view and Fig. 4 is a si e view of the top and end frame; Fig. 5 is an end view and Fig. 6 is a side view of the detachable sides; Fig. 7 is an end view and Fig. 8 is a side view of the base; Fig. 9 is an end view of the assembled aress with the plunger down and showing tie molded glass in broken lines; and Fig. 10 is a longitudinal sectional view taken on the line V W of Fig. 9, omitting the glass; Fig. 11 is a. perspective view of the molded form of glass; Fig. 12 is an end view and Fig. 13 aside view of one end of a modified form of plunger; Fig. l t is a crosssectional view taken on the line X X of Fig. 15 which is a longitudinal sectional. view of one end of the modified form of top and end and mold body to be used with the modified plunger shown in Figs. 12 and 13; Fig. 16 is a cross-sectional View taken on the line Y Y of Fig. 17 which is a longitudinal sectional view of another modified form of top and end plate combined with a mold body, like that shown in Figs. 14: and 15, and Fig. 18 is a cross-sectional view taken on the line Z Z of Fig. 19 which is a longitudinal sectional view taken on the line Z of Fig. 1.8, of one end of a modified form of mold-press for making coves or bases.

In all the figures corresponding parts are referred to by similar reference letters.

The obj ect of my improvements is to produce, by a single operation of a reciprocating plun er, a glass tile having a smooth, fimshed ace on one side, and oppositel inclined undercut lugs upon its other si e or And this may be accomplished by the back.

use of the form of mold press illustrated in Figs. 1 to 10 inclusive, or by the use of the modified forms illustrated in Figs. 12 to 19 inclusive.

In the first mentioned form my pressmold is provided with a base or body A having a centrally disposed gutter or groove B, shown by broken lines in Fi "s. 7, S and 9, and also havin raised ends 6 C preferably provided with c epressions c 0 upon the tops thereof.

Removable side members D D rest upon the base A, and the top E rests upon the side members D D with its depending ends F F fitting inside of the same and resting upon the raised ends C C of the base.

The plunger Gr has its nose H shortened so as to pass down between the raised ends C C of the base, while the body of the plunger extends out over the raised ends 0 a so as to overlap the same, as shown in Fig. 1.0. The plunger is provided with recesses 71. it adapted to form the upper lugs on the back of the tile, and with other recesses h It ada )ted to overlap the corners of the raised en s C C and to leavebetween them and such corners recesses of the form shown by the broken lines in Fig. 9, and ada )ted to form the lower hook-like lugs. u on t e tile.

It will be seen that when mo ten glass is placed in the body of the mold and the plunger is forced down upon it, the lass will be spread up into the sides and en s of the mold, and forced into the recesses in the plunger, so as to take the form shown in Fig. 11. The plunger may then be raised, coming freely away from the molded glass, the top and ends removed, and the sides then lifted off the base, carrying the molded form of glass with them, which may afterward be annealed and separated into its tile sections. The slight space between the ends of the plunger and the ends of the mold, and the recesses upon the tops of the ends of the mold cooperating with slight corresponding recesses in the plungers ends, will produce end webs I I with their top webs z i shown in Fig. 11, which serve to stiffen the molded form of glass during the process of handling and annealing. It will be seen that by breaking or cutting away the gutter web J and the end webs I i, the com leted tile sections K K will remain with the ugs k is inclined in one direction, and with hook-like lugs k 70 inclined in the other direction. Such lugs are of advantage in firmly locking a tile upon its backing. 1

In the form of press just described, the tile is formed with its finished face down and its lugs up. But in the modified forms of press, shown in Figs. 12 to 19 inclusive, the tile is formed with its smooth face up and with its back and lugs down. This is accomplished in the form shown in Figs. 12 to 15 by forming in the mold body A recesses a a and attaching to the outer edges of the plunger G spurs g g which pass down through suitable recesses e e in the top E so as to rest within the recesses a a in the position shown by the broken lines in Fig. 14. This, as will be seen, will form an undercut portion in the recesses a a. so that when the plunger is brought down upon the melted glass it will be molded into the form shown by the broken lines in Fig. 14, with inclined lugs near the lower edge of each tile section, and an oppositely disposed hook lug at the upper edge of each tile section. And by raislng the lunger and removing the top this molded orm can be removed from the mold by turning the mold over.

In the modified form shown in Figs. 16 and 17, spurs g 9, shown in broken lines in Fig. 16, are attached to the top E and fit within the recesses a a, so as to form undercut sockets therein of a form like those formed by the spurs g 9 shown in Figs. 12 and 14. A plunger having a face corresponding with the upper broken lines shown in Fig. 16 is used; and it will be seen that by withdrawing the plunger and raising the top E the molded tile form can be readily freed from the mold by turning it over.

The mold shown in Figs. 18 and 19 embodies the same principle illustrated in Figs. 16 and 17, and shows it applied to forming a curved tile, commonly called a cove; recesses a a being formed in the body A, into one of which a lug g fits to form an undercut socket, while the opposite edge of the top E overlaps the other recess a so as to form it also into an undercut socket. And it will be seen that the molded glass may be readily removed from this form of mold also, by raising the plunger G and removing the top.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is

1. The combination, in a glass-tile moldpress embodying a male member and a female member, of a lug-socket having portions disposed successively at angles oppositely inclined to the tile-face forming portion of the mold.

2. The combination, in a glass-tile moldpress embodying a body-base and a reciprocating plunger, of a lug-socket having portions disposed successively at angles oppositely inclined to the tile-face forming portion of the mold.

3. The combination, in a glass-tile moldpress embodying a body base and a recipro cating plunger, of a lug-socket formed between the mold-press members and having portions disposed successively at angles oppositely inclined to the tile-face forming portion of the mold.
