MANUFACTURE OF TILES, BRICKS, AND THE LIKE.
Specification of Letters Patent.
Patented Au 8, 1905.
Application filed September 27, 1904. Serial No. 226,212.
To all whom it may concern:
Be it known that I, JOHN HENRY MARLOW, a subject of the King of Great Britain and Ireland,and a resident of Edin burgh,in the county of Mid-Lothian, Scotland, (whose postal address is 15 Temple Park Crescent, Edinburgh, Scotland,) have invented certain new and useful Improvements in or Connected with the Manufacture of Tiles, Bricks, and the Like, (for which I have obtained a British patent, No. 11,803, dated May 2 1, 1904,) of which the following is a specification.
My said invention relates more particularly to the dies used for recessing and undercutting the recesses so formed in tiles, bricks, and the like, and has for its object to improve the construction and action of such dies, so that a clean and satisfactory undercut recess is formed in a simple and expeditious manner.
In carrying out my invention the upper part or that part of the die which forms the undercut recess consists of two plates loosely connected. To the under side and preferably at each end of the upper plate there are adjustably connected what might be termed two plungers, adapted to work in and forming counterparts of two slots which extend completely through the lower plate. The lower plate has formed on or fixed to its under side and preferably at each end thereof a dovetailed piece of any convenient shape, and the slots hereinbefore referred to pass down on each side of the dovetailed piece. These slots are horizontally inclined and pass through the lower plate obliquely, so that they are farther apart on the under side of the plate than on the top. The upper plate is capable of being raised a predetermined distance before the lower plate is raised, and this insures that the plungers are withdrawn from the undercut in the recess formed in the tile before the dovetailed piece on the lower plate is withdrawn from the recess in the tile. In order that my said invention and the manner of performing the same may be properly understood, I hereunto append a sheet of explanatory drawings to be hereinafter referred to in describing my improvements.
Figure l is a sectional end elevation showing the die in the position for forming an undercut recess. Fig. 2 is an inverted plan of a part of the upper plate, showing the method of adj ustably connecting the plungers. Fig.3 is an inverted plan of a part of the lower plate, showing the plungers as having been withdrawn from the undercut recess in the tile. Fig. 4 is a back view of a tile after the recess and undercut have been formed, while Fig. 5, 6, and 7 are respectively sections of tile as taken on the dotted lines a 7), c d, and c f. 7
In the drawings the same reference-letters are used to mark the same or like parts wherever they are repeated.
As shown in Fig. 1, a box or receptacle A, which may be of any convenient form or shape, is provided with the usual bottom plate B, which can be raised or lowered by means of a rod 0, and the tile-forming material D is placed on this plate. The upper part of the die consists of two plates E F, loosely connected. for example, by means of pins (not shown) fixed in one plate and working in slots in the other plate, so that the upper plate E can be raised to the extent indicated by the dotted lines before the lower plate F commences to rise The upper plate E is smaller than and works within the lower plate F, and to theunder side of the upper plate and preferably at each end thereofithere are adjustably conering-plate J, as shown in Fig. 2, so that the plungers can move horizontally and vertically away from or toward each other. These plungers G H work in slots K, which extend completely through the lower plate F.
As shown in Fig. 3, 'a dovetailed piece L, which may be of any convenient shape, as may be found most suitable in practice, is formed on or fixed to the under side and preferably at each end of the lower plate F, and this dovetailed piece forms the body of the recess in the tile, while the plungers G H form the undercut. In Fig. 3 the plungers are shown in the position they will occupy in the slots K when the upper plate E has been raised to the height indicated by dotted lines in Fig. 1.
As shown in Fig. 4, the extent of the undercut in the tile is indicated by dotted lines on each side of the recesses M; but, if desired, the undercut may be formed along more than two sides of the recess.
In the case of large tiles any convenient number of undercut recesses may be formed and they may be disposed in such a way as may be found most convenient in practice. In the case of narrow tiles the dovetailed piece L for forming the main body of the recess M may be dispensed with, and the plungers Gr H may be so disposed as to form a single undercut recess at each end of the tile.
I will now describe the operation of forming an undercut recess in a tile according to my invention. The two plates E F, forming the upper part of the die, are 'raised sufficiently far to allow of the tile-forming material D to be placed on the plate B in the box or receptacle A. The plates E F are now forced down on the top of the tile-forming material, and by means of the dovetailed piece L and plungers G 1-1 working in the slots K an un.
dercut recess M, such as is shown in Fig. 1, is formed 1n the tile. After the necessary pressure has been applied the upper plate E, carrying the plungers G H, is raised to the position indicated by the dotted lines in Fig. 1, and the plungers are now clear of the undercut in the tile and the upper and lower plate having slots therein in which the plungers work.
In witness whereof I have hereunto set my hand in presence of two witnesses.
JOHN HENRY MARLOW. WVitnesses:
ROBERT LUIKLATER, GEORGE PATTERSON.
