BmcK-cUr-orr TABLE.

The 4present invention relates to brick cut of tables wherein peculiar shaped brick are cut by a wire or arseries of wires passing transversely through a column ofy clay, theV column of clay resting and moving upon a platen or support, abovewhich column of clay is located an upper or top platen ar ranged parallel withthe clayy column supporting platen, i

The objectsl of the present invention are, first, to provide means for guiding the brick cutting wire or wires and second,to so guide the wire or wires that the column of clay will be cut into "blocks of the desired size, the faces of which are provided with what might be termed opposite concaved' andconvexed faces, the convexity and concavity of the faces beingdivided about midway between the longitudinal centers of the brick or blocks. l attainthese objects together with other objects readily apparent to those skilled in the art by the construction and arrangement of the various devices illustrated in the accompanying drawingsy in whichl Figure 1 is a side elevation of the cut off table showing the column formingv die. Fig. 2 is atop plan view of the same# Fig. 3 is a transverse vertical section on line 3 3, Fig. 2. Fig. 4c is a longitudinal vertical section showing the position of the cutting i wires at their positions midway between the ends of the brick or substantially so. Fig. 5 is a similar view showing the position of the wires at the beginning of the cut or at the end of the cut. Fig. 6 is a plan view showing a portion of the top platen illustrating the slots in the lower platen in dotted lines. Fig. 7 is a top plan view of a portion of the bottom or clay supporting platen. Fig. 8 is a perspective view of a cut brick or block produced.

Similar numerals of reference indicate corresponding parts in all the ligures of the drawing.

In the accompanying drawings, 1 represents the die which is connected tor an ordinary brick machine which machine within itself 'forms no specific part of the present Specification of Letters Patent.

invention. The top platen 2 and the bot-` tom platen 3 are connected to the thrust bars 4 yby means of the flanges V5 and the clamping bolts 6 or their equivalents, the only object and purpose beingto space the platens 2 and 3 so that the column of clay will pass between the two platens, said platens being so arranged with reference to each other that the upper platen will be spaced ashort distance from the top of the column ofy clay, this being preferablevas by sofspacing the platens there will be no frictional contact as between the upper face of the column of clay and the bottom or undery thrust bars are connected tothe movable frame 7, which frame within itself may be Y of the ordinary construction and is mounted upon suitable traveling rollers or wheels 8, which travel back and forth upon suitable tracks or ways 9. It will be understood that the frame 7 together with the different parts carried by said frame must necessarily travel in unison with the travel of the clay column adjusting ythe* die of the brick machine during the time the cutting wires are passing'through the column of clay and in order to accomplish this simultaneous movement of the frame carrying the cutting wires and the `columnrof vclay the usual mechanism for intermittently and automatically moving the frame with the column of clay must be provided but such mechanism is well 1 known in the art and has no specific reference yto my present invention and for that reason such mechanism is not illustrated but it will be understood that in order to carry out the complete working of a brick cutting machine such mechanism mustvnecessarily be present.

The top platen 2 and the bottom platen 3 are provided with the curved slots 10 and 11, which slots are formed of suiiicient length to allow the cutting wires to move back and forth suliicient distance to pass through the column 0f clay. For the purpose of producing a brick or block such as shown in Fig. 8 the curved slots 10 and 1l are arranged as shown in full lines and in side of the top platen 2. These platens 2 f e and 3 are carried by the thrust bars 4, which dotted lines Fig. 6; that is to say the slots in l 10 and 11, the cutting wire or wires will fol` low the curvatureV of the slots and by reason of the fact that the slots in the 'lower platen are Ycurved in the opposite direction from the slots in the upper platen the wireor wires will change position during the movement.

of the wire` or wires, the movement being such as to give to the faces of the' brick, thel curvature illustrated in Fig. 8. In Fig. 4E the wires are shown in their positionsassumed about midway between the eXtreme movements ofthe Wires and in 5 the wires are shown in their positions assumed at the beginning of the cut or at the formation of a cut. By providing curved 'slots' in' the top and bottom platens and spacing, said platens from each other a sufficient distance to allow a column of clay to pass between said platens, the wire or wires will in a sense be oscillated, that is to say` the lower portions of the wire will be moved through the arc of a circle and the upper portion of the wire will be moved in a similar arc but of opposite curvature, thereby producing a bars 13 being provided with the usual con-V necting heads 14, whichfare provided with the springs 15, but these parts are'common in brick cut off tables and need no specific description as the only object is to hold the wires in proper tension andrso far as the .Copies of this patent may be obtained for present invention'is concerned may be of any wellknown mechanical construction.

does not take place but they cross each other in different horizontal planes so that the ends of the slots are located in di'erent vertical planes, by which arrangement the cutting wire or wires are not in a true vertical position at vany time, except when the wires are at thek points where the slots cross each other in dierent horizontal planes.Y

Having fully described my invention what I claim as new and desire to, secure byLetters Patent, is-

In a brick cut off table, a cut 01T frame, a lower platen adapted to support a column of clay, said platen provided with. a series of transverse curved slots, an upper platen located above said column of clay, said upper platen provided with a series of transverse, oppositely curved slots, a bar adapted to reciprocate transversely above thev clay column, a second bar adapted to reciprocate transversely beneath the clay column, and wires carried between said bars, said wires located through the oppositely curved slots in the upper and lower platens.

In testimonyY that I claim the above, I have hereunto subscribedl my name'k in the presence of two witnesses.
