T0 at whom itmaty concern.-

Be it known that I, WILLIAM FREY, a citizen of the United States, residing at Canton, in the county of Stark'and State of Ohio, have invented certain new and useful Improvements in Brick-Gut-Off Tables, of which the following is a specification.

My invention relates to a series of transverse dies operating on each side of the wires in a brick-cut-off table for smoothing or rounding the edges and, if desired, to impress the intervening faces of the bricks; .and the objects of the improvements are to smooth or round the edges and to smooth the faces antomatically at the same time the cuts are made. I attain these objects by theconstruction and mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of parts of a brick-machine and of acut-off table, showing the dies adapted thereto; Fig. 2, a transverse section-of the cut-01f table; Fig. 3,2. similar section showing the manner of operating the dies; Fig. 4:, a longitudinal middle section of the cut-0E table with the cut-off frame in the middle position, as shown by broken lines in Fig. 3; and Fig. 5, afragrnentary section showing the dies arranged to impress the intervening faces of the bricks.

Similar numerals 'refer to similar parts throughout the drawings. I

In the manufacture of bricks by the stifi mud process the clay column 1 as it emerges from the mouth 2 of the brick-machine 3 is cut across by wires,as 4, at suitable intervals for forming the bricks. The wires are attached in a cut-off frame, as 5, to the bar 6 below and to the tension hooks 7 above, which parts or similar ones are ordinary in cutoff tables. On each side of the clay column I provide a series of plates 8, which substantially correspond in height and width to the ends of the bricks to be cut and are spaced apart, with the'narrow intervals 9 between them. The side plates are joined on the ribplates 10, and the rib-plates are attached to the body of the cut-01f table by means of posts, as 11, at each end. The rib-plates are provided with the transverse slots 12, which open into the intervals between the side plates and receive the cutting wires at the end of each cut. The table-plate 13 is at- Serial Fe. 149,619. (No modek) tached to the cut-0E frame at each end and is provided with the transverse slots 14, in which the cutting-wires and the lower dies operate.

The upper die-frame is composed of the transverse die-bars l5 and the longitudinal connecting-bars l6, and these bars are preferably securely joined at their intersections by rivets or otherwise. The upper die-bars 16 are provided with the longitudinal slits 17, in which the cutting-wires are free to operate, and on each side of these slits, on the under side of the die-bars, are formed or attached the edge dies 18, which are formed concavely or otherwise to mold the brick edges to the desired shape. The upper die-frame is held in proper place by the guide-posts 19, which are attached on the rib-plates and extend upward through the apertures 20 in the die frame, which apertures are preferably slightly slotted transversely of the frame to give freedom to its movements. The upper die-frame is normally located above the clay column, so that the lower edges of the dies freely clear the same, in which position the frame is sustained by the coil-springs 21, which are preferably located around the guide-posts and rest on the rib-plates. The lower die-frame 8c is similarly composed of the die-bars 22 and the longitudinal connecting-bars 23. In the lower die-bars are likewise provided the longitudinal slits 24 for the cut-off wires, on each side of which slits are formed or attached the edge dies 25. Thelower dies operate in the transverse slots 14 of the table-plate and are normally located so that their upper edges freely clear the clay column.

The links 26 are pivoted on each side of the 0 upper die-frame, and the lower ends of these links are pivoted to the outer ends of the reversing-levers 27, which reversing-levers are in turn pivoted to the lugs 28 on the ribplates. The links 29 are pivoted on the inner 5 ends of the reversing-levers, and the lower ends of these links are pivoted to the lower die-frame. The inner ends of the reversinglevers are preferably bifurcated to receive the cut-off wires, and the links 29 operate in the transverse slots 14 of the table-plate. By this lever-and-link connection when the upper die-frame is depressed to bring the upper dies down to mold the edges on the upper side of the clay column the lower die-frame is automatically elevated to raise the lower dies to mold the edges on the lower side of the clay column. As there should be more clearance between the clay column and the dies above than below, on account of the slightlyvarying thickness of the clay column, I prefer to make the outer arms of the reversinglevers longer than the inner arms, which arrangement brings the upper and lower dies into effective operation at the same time.

The tread-bars 30 are transversely located at intervals on the upper die-frame and have elevated sections 31 in the middle, substantially corresponding to the width of the clay column, from which elevated section the upper faces of the bars incline downward toward each end. The tread wheels or rollers 32 are journaled in the brackets 33, which are attached at intervals on the cut-off frame and are so located that the tread-wheels will travel on the tread-bars as the cut-0E frame moves transversely in making the alternate cuts. The parts are so located and arranged that the tread-wheel rests on the tread-bar at the lower end of the inclined part when the cut-off frame is at the end of its side-wise movement, and in this relation the upper and lower die-frames are in their normal positions, as shown in Figs. 1 and 2. When the cut-ofl' frame starts in its sidewise movement to make a cut, the tread-wheels first depress one side of the upper die-frame and correspondingly elevate the same side of the lower die-frame by traveling on the inclined part of the tread-bar, as shown in Fig. 3, and when the tread -wheels reach the middle of the tread-bars the entire upper and lower dieframes are depressed and elevated, respectively, so that the edge dies above and below are squarely pressed into the clay column, as shown in Fig. 4 and by broken lines in Fig. 3, thus forming the smooth or round edges at the same time the wires are cutting the brick between the edge dies. As the cutoff frame completes its movement the operation of the frames is just reversed by action of the spiral springs, and when the movement is completed the edge dies stand free above and below the clay column ready for another operation.

It will be understood that the die-frames can be so guided and stayed that they will move squarely up and down; but I prefer the rocking movement, because it requires less power to operate the dies, and there is also a slight endwise rubbing of the dies against the edges of the bricks, which gives a greater smoothing effect. The upper edge dies can also be joined between the respective wires, and the entire upper surface of each brick impressed by the die, if desired, as shown in Fig. 5; but for general purposes I prefer to confine the dies to the edges of the bricks.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In a brick-cut-off table, a cut-0E frame, a depressible die operating against the clay column, a tread-bar on the die, and a wheel in the frame traveling on the bar.

2. In a brick-cut-oif table, a cut-off frame, a depressible die operating against the clay column, a tread-bar on the die having inclined ends, and a wheel in the frame traveling on the bar.

3. In a brick-cutoff table, a cut-off frame, a depressible die above and a reciprocating die below operating against the clay column, a tread-bar on the depressible die, and a wheel in the frame traveling on the bar.

L. In a brick-cut-otf table, a cut-off frame, a'depressible die above and a reciprocating die below operating against the clay column, a tread-bar on the depressible die having inclined ends, and a wheel in the frame traveling on the bar.

5. In a brick-cut-off table, dies above and below the clay column, reversing-levers pivoted on the table, links connecting the dies to the respective ends of thelevers, and means for depressing the upper die, whereby both dies impress the column.

6. In a brick-cut-off table, a cut-off frame, a plate in the frame operating under the clay column, a transverse slot in the plate, and a die-frame below the plate having a die operating in the slot against the clay column.

7. In a brick-cut-otf table, a cut-off frame, a cut-off wire in the frame, dies impressing the clay column above and below while the cut is being made, and slitsin the dies through which the wire operates.

8.. In a brick-cut-off table, a cut-off frame, a cut-off wire in the frame, a die impressing the clay column while the cut is being made, and a slit in the die through which the wire operates.

9. In a brick-cutoff table, a cut-off frame, a cut-off wirein the frame, and a die impressing the clay column alongside the wire while the cut is being made.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
