BRICK AND TILE MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,698, dated October 23, 1888.

Application filed February 16, 1888. Serial No. 264,293. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK E. FREY, a citizen of the United States of America, residing at Bucyrus, in the county of Orawford, in the State of Ohio, have inventeda new and useful Improvement in Brick and Tile Machines, of which the following is a specification.

My invention has relation to improvements in automatic cut-offs for brick and tile machines; and the object is to provide a cut-off to sever the slab or column of clay into lengths on the carrying-belt of the tile-table, which cut-off is operated by the carrying belt, impelled by the movement of the unsevered part of the slab of clay as it progresses from the ma chine.

The novelty of the invention audits nature are specially pointed out in the claims made hereto.

I attain the purposes of my invention by means of the mechanism illustrated in the accompanying drawings, wherein Figure l is a perspective of my improvements attached to a brick-machine. Fig. 2 is a perspective of a section of the endless belt, showing the angle-irons or arms which operate the cut-off. Fig. 3 is a detail view of a pair of the angleirons removed from the belt. Fig. 4 is a perspective of the reel with the cutoff wire. Fig. 5 is a plan view of the tables. Fig. 6 is a modified form of the table and cutoff. Fig. 7 is a detail view of the supportingbracket for the cut-off.

The same parts appearing in the different figures of the drawings are designated by the same notations, and reference being had there to, A designates the frame of the tile-table. which consists of parallel side pieces, 1, united by suitable cross-ties and supported on legs, as at 2. The side pieces are arranged at such distance apart as to take between them the endless carrying-belt B, which is arranged on rolls or drums 3 4 at each end, the former of which is of larger diameter than the latter to give greater frictional surface in its contact with the endless belt; but both drums are arranged to carry the upper line of the endless belt on a horizontal line and a little flush of the upper surface of the side pieces of the frame. A

series of rollers, 5, as indicated in Fig. 6 of the drawings, is journaled in the side pieces and sustain the endless belt in a horizontal position and from sagging below its proper line of movement. Secured to and arranged across the endless belt B are a number of metal rods, 6, or cross-bars, the ends of which project be youd the edges of the endless beltand over the sides of the frame and are formed withjournals 7 on the projecting ends, andsecured and fitted on thejournals at each side of the endless belt are angular irons 8, consisting of two arms arranged at right angles, which are pivoted on their hearings in the intersecting angle of the arms, the angle on the outside being rounded to prevent them from catching as they are moved over the ends of the belt-supporting rollers in the frame. These irons 8 are the means by which the reel of the cut-off is rotated and made to perform its duty of cutting off the forms. They are placed at determined distances on the belt in order that the slab may be severed in the desired lengths. On the carrier-belt between the cross-bars 6 are secured pads of felt, 9, or any other suitable yielding material, upon which the continuous slabs of clay are pushed and are carried along on the apron upon them. These pads serve the following purposes: First, they keep the clay from contact with the crossbars on the apron, thus preventing the under side from being damaged; second, they afford a yielding bed for the outting-wires to impress themselves slightly below the under surface of the column of clay. It will be observed that when the wire is traversing the space where the cutting-arm of the reel is vertical it moves somewhat faster than in the other regions of the cutting arc, owing to the peculiar engagement of the arm of the reel with the vertical arm of the angular iron. To carry the forms out of the way of the Wire, a secondary table is provided, hereinafter described, the apron of which moves faster than the apron of the main table, so that when the form is severed it is in contact with the apron of the secondary table and is drawn out of the way of the wire in its ascending movement.

Secured on each side of the table-frame is a bracket, 10, in which are adjustably arranged the stems .of bearing-boxes 11, in which are mounted the journals of the shaft 12. On the reel is secured a small roller, 15, which engages with the angular irons 8, and as these irons move forward the rollers are run down the length of the iron, causing the roll to rotate, and of course carry the wire through the clay. The horizontal arm of the iron serves as a base-piece to keep the vertical arm of the iron from yielding backward. The small rollers serve to keep the movements synehronistic. As itwillbe perceived,in order to obtain a square cut, the clay, the endless belt, with the angular irons and the reel, must all be moved in unison, a condition which permits the wire on a revolving cutter to cut square through the longitudinally moving body beneath it. It will be perceived that this is accomplished simply by making the slab serve as the power to revolve the cutoff. It is essential that the cutting-wires be arranged on a line with the axes of the rollers on the reel-arms; otherwise the cut will be curved. I therefore attach to the inner faces of the reel-arms small spring-supports 23,with open end slots, 24:, in which the cutting-wires are seated. In the supports 23 are set'screws 25, by which the tension of the wires is adjusted.

G designates the second or auxiliary table, which consists of side rails, 16, connected together by cross-pieces and mounted on supports of any suitable kind, substantially as shown. In each end of this frame is journaled a roller, l7 18, about which is stretched an endless apron, 19, to receive and carry the forms from the main table. The shaft of one of the rollers is extended and has fixed thereon a band-pulley, 20, on which is arranged a belt, 2I,which is extended and arranged about a larger pulley, 22, on the shaft of the drum of the main carrying-belt. It will be per ceived that the endless apron of the secondary table is driven by the motion of the endless apron of the main table and primarily by the movement of the clay from the machine, and also that the power is so arranged as to drive the apron of this secondary table faster than the apron of the main table.

To prevent distortion or breakage of the forms in their passage from one table to the other, I arrange a small roller, 26, between the adjacent ends of the two tables to carry the forms. I prefer to support this roller on bearings 27 on the side pieces of the main table and give it rotary motion by small belts 28, extended to and arranged about the end roller of the secondary table.

In Fig. 6 of the drawings I have shown a modified arrangement and construction of the angular arms and reel in connection with the slab of clay and apron of the main table. In this construction I arrange a shaft, 29, under the main table and on the end fix a sprocketwheel, 30. The end of the shaft of the roller or drum 3 is extended, and a sprocketwheel, 31, is fixed on the extension, as shown, and about these sprocket-wheels is arranged an endless belt, 32, on which at predetermined distances are pivotally secured the angular irons 8. I also extend the shaft 12 of the cutofif and mount thereon a spider of the sameconstruction of the spiders of the reel, as hereinbefore described. The operation and result are identical with that attained by the construction herein first specified.

In the passage of the euttingwires through the clay it happens that clay will adhere to them. In order that they may be cleaned, I arrange a brush to contact with them and brush off the adhering clay. The device consists of a frame, 33, the legs of which are adjustably supported in the bracket 10, substantially as shown, and on the horizontal bar of the frame is secured a brush, 34. To catch the sweepings from the wires, I suspend a trough, 35, on the shaft of the reel, as shown.

What I claim is 1. The combination, with a brick-machine, of a tile-table provided with an endless apron adapted to be moved by the progression of the column of clay, angular irons pivotally secured to said apron at predetermined distances, a cut-off reel mounted over the end less aprons, and rollers on the ends of the arms of the reel to engage with the vertical arms of the said angular irons, substantially as described, and for the purpose stated.

2. In a tile-table of the kind herein described, an endless carryingapron having a continuous inner surface and a covering of felt divided into sections, substantially as described.

3. In a tile-table, the combination, with the endless carrying-apron, of angular irons, as 8, pivotally mounted on cross-bars secured on the apron, pads of a yielding material secured on the endless apron between the said crossbars, and a cut-ofi' mounted over theendless apron and adapted to be operated by the vertical arms of the angular irons, substantially as described.

4. The combination, in a tile-table, of an endless apron, angular irons 8, pivotally secured on the said apron, a cut-off reel mounted over the endless apron. rollers on the ends of the arms of the reel to engage the vertical arms of the angular irons, a secondary tile-table at the end of the main table provided with an endless carrying-apron, and means, substantially as described, for moving the endless apron of the secondary table, as specified.

In witness whereof I have hereunto set my hand in the presence of two attesting witnesses.

FREDERICK E. FREY.
