S. G. BRINKMAN. TILE CUTTING MACHINE.

No. 600,856. Patented Mar. 22,1898.

F/Gfi. 06.5.

TILE-'CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,856, dated March 22, 1898.

Application led June l0, 1897. Serial No. 640,134. (No model.)

To @ZZ whom it may con/cern,.-

Be it known that I, SEBASTIAN G. BRINK- MAN, of New York city, county and State of New York, have invented an Improved Tile- Cutting Machine, of which the following is a specification.

This invention relates to a machine for subdividing tiles into smaller sections, the invention being more particularly designed to iit the tiles for fireproof partitions.

By my invention I can cut the tiles in a quick and accurate manner without producing chips, breakage, or waste.

In the accompanying drawings, Figure l is a side elevation of my improved tile-cutting machine, the front half of the bed-plate being removed to expose the lower cutter. Fig. 2 is a vertical cross-section on line 2 2, Fig. l, showing the upper cutter raised; Fig. 3, a similar section with the upper cutter lowered; Fig. 4, a detail face view of portion of one of the cuttingblades; Fig. 5, an end view of one of the teeth; and Fig.V 6, a cross-section on line 6 6, Fig. 4.

My machine consists, essentially, of a frame carryinga pair of cutting-blades, of which one is movable, and provided with teeth of such a construction that they will wedge into and divide the tile without chipping or breaking it.

a d represent the split standards of the machine, braced, as at b, and provided with a Xed lower blade c and an upper verticallymovable blade d, though of course the lower blade may also be made movable.

In order to impart a powerful stroke to the movable blade, I prefer to employ the construction illustrated, and in which such blade is attached to a slide e by toggles e', while the slide is in turn attached to a beam et of the frame by toggles e2. The ,slidee is actuated by hand-lever f, fulcrumed to the machineframe at f and connected to the slide by means of a link f2. If the hand-lever is depressed, the slide will be drawn outward and will simultaneously descend to lower the blade d, which is guided in a rectilinear direction by means of abutments d', gliding along the standards a. A raising of the handlever will cause a corresponding raising of the slide and blade CZ, as will be readily understood.

The lower blade c is flanked by the two secper blade and is thus depressed the bed will descend beneath the cutting edge of the lower blade, so that both blades may simultaneously operate upon the tile, Fig. 3.

The teeth d of the serrated cutting-blades are so shaped that they operate as wed ges and exert a lateral thrust within the grooves cut. To this effect each tooth increases in thick ness not only from point to root, but also transversely from both of its inclined cutting edges toward the center, which I make in the form of a rounded corner d2, Fig. 6.

"While the cutting edges of the blade are in a plane with the body of the blade, the cleaving edges cl2 are at right angles thereto, so

that the teeth are diamond-shaped in crosssection. The edges d2 extend to the roots of the teeth, while the adjacent inclined surfaces of the teeth are joined around the points of the rentrant angles of the blade, as shown, to form a beveled clearing-surface.

Cutting-blades of this construction need only to enter the tile for a comparatively short distance, when by means of the lateral wedgelike action produced within the grooves cut the core of the tile will be split in a line between the grooves to produce a clean and very reliable cut. g

By my machine I am enabled to form, more especially, the odd pieces of tiling used in building up a reproof partition in a quick, accurate,and convenient mann er and without producing waste or chips or running the danger of destroying the tiles entirely, as frequently occurs by hand-splitting.

The fireproof earthernware baked tiles which I contemplate to cut are of a very tenacious nature, and I have found that by the peculiar construction of cutting and @leaving tooth described a quick, clean, and accurate division may be effected.

l. A cutting-blade having a serrated edge formed of pointed teeth diamond-shaped in cross-section, and vpresenting cutting edges in line with the body of the blade, and cleaving edges at right angles thereto, said cleaving edges extending to the bases of the teeth, the adjacent surfaces of the teeth bein g joined to form a beveled clearing-surface, substantially as specified.

2. A tile-cutting machine composed of a frame, a loWer and upper blade having Wedgeshaped teeth, a slide, means for actuating the slide, toggles that connect the slide to the upper blade and to the frame, and of a divided 1o spring-supported bed embracing the lower blade, substantially as specified.
