The defects in this device are in that 50 of the brick; also to cause said supporting the end of the bar is not, so to say, suffi- 10o ciently retarded to prevent the aforesaid breaking of the clay at the bottom of the cutoff while the latter is being effected, and, secondly, in that the position the roller is required to occupy is such that it is struck by each of the cut-off wires in the course of the rotation of the cut-off belt or wlieell This invention, which will now be described, fully obviates the aforesaid defects which interfered with the perfect operation of the ma chine.

Referring again to the drawings, F is avertically-sliding plate located under the advancing clay bar X about the distance of half the length of a brick,'or in front of the point of complete severance of the bar, as seen clearly in Fig. 1, so that when the brick m is about to be entirely out off it is supported by said plate, and, being about balanced, it has no tendency to drop and break off. The plate is made with a flat top and beveled or dropping edge toward the cut-off, as shown, so as to insure that the end of the clay bar will properly strike and slide upon the plate. The friction of the clay upon the surface of the latter holds back the projecting end, thus insuring the coherence of the yet unsevered part of the clay on the line of cut-off, so that when the wire reaches near the bottom of the bar the almost-severed end is prevented from being moved or jumped forward by the final force of the wire as it cuts through. In this way the heretofore breaking off or raggin'g of the lower edge of the brick is obviated. It is necessary that this plate should be dropped or moved out of the way of the wire; otherwise it would be struck by the latter as the cut-off wheel A, which carries the series of wires, continues in its rotation. The top of the plate must also be nicely adjusted to the line of the under side of the clay bar. A combination of mechanism will now be described,although it is here remarked that the invention is not confined to the particular mechanism shown.

The plate F WOlkS in a guide-box, G, which is secured to the frame It. To its lower extremity is pivoted one arm, K, of a rock-lever on the end of shaftj, journaled in brackets e on the under side of frame It. On a stud, e, projecting from the other arm, K, of said le- 'ver at about right angles thereto, is pivoted a rod, J, made in two parts-one with arighthand and the other with aleft-hand screwthread-with an adj usting-nut, n, and setnuts 77/, whereby the length of the rod may be readily shortened or lengthened at pleasure. The upper portion of said rod is flattened, and extends through a guide-slot, 01 in an an gle-bracket, O, that is bolted to the side of the frame. A spring, S, connects the projecting ends of the fixed bracket ()and the arm K of the rook-lever, the stress of the spring tending to draw up the said arm, and consequent'y odepresstheslidi *gsupportingplate F. A roller, r, is journaled on the free end of rod .T, which roller rides upon the edge of a circular disk, P, upon the shaft a a, that bears the cut-off wheel and belt and tappetwheela which shaft is journaled in abort, q, upon the standard q Fig. 2. Said diskis provided with depressions T, with rounded ends, the number of which depressions and intervening elevations, T, respectively, s equal to that of the cut-off wires. The posltion of roller 0" is such that it rides against the edge of the disk, being held there by the stress of the spring S. \Vhen the roller is riding upon the elevations of the disk, the plate F is retained in the position where 1t performs its function of supporting the projecting ends of the clay bar; but as the disk continues its rotation the spring causes the roller to enter the depressions, and obviously at the same time the arm of the lever is raised up, and by the sequence hereinbefore described the plate is drawn down out of the way of the cutoff wire, and is then held a sufficient time (regulated by the length of the depression) until it is again elevated by the roller riding upon the elevated portion of the disk. It will of course be understood that the arrangement of the devices is such that the raising, retaining, and dropping of the sliding plate shall successively occur and continue at and during such intervals as will effect the purposes of the invention.

In the drawings one of the wires has just completed the cutting off of a brick from the bar of clay. The roller 1' is about to drop into a depression upon the cam-disk, which occurring, the plate will be dropped and the brick be permitted to descend flatly upon the offbearing-belt.

Having thus described the invention, that which is claimed as new, and for which Letters Patent are desired, is

1. In a brick-machine of the class recited, the combination, with the continuously-moving belt E and the rotating cut-off device arranged with relation thereto, substantially as shown and described, of the plate for supporting and retarding the advancing end of the bar of clay while a brick-length is being severed therefrom, said plate being located between the point of severance and delivery beyond said belt, substantially as described.

2. In a brick-machine of the class mentioned, the combination, with the rotating cut-off devices, of the supporting-plate located with relation to the point of severance of the clay bar, as shown and described, together with mechanism, such as shown and described, for bringing and retaining the plate in position to support the end of said bar and for moving the same away from such supporting position out of the path of the cutolf wires, substantially as and for the purpose set forth.

3. In a brick-machine of the class mentioned, the combination, with the rotating cut-off devices, of the vertically-sliding plate located relatively to the point of severance of the clay bar, as shown and described, the rocklever, the rod, the bracket, the spring, and the disk having the elevations and depressions, all constructed and adapted to operate substantially as and for the purpose set forth.

4. In a brick-machine of the class mentioned, the combination, with the rotating cut-off devices, of the belt for carrying the clay bar, the offbearing-belt with its surface below the said carrying-belt, the supportingplate located with reference to the point of final severance of the clay bar, as shown, together with the mechanism for elevating, depressing, and retaining said plate, all constructed and adapted to operate substantially as and for the purpose set forth.

5. In a brick-machine of the class mention ed, the combination, with the rotating cut-off devices, of the vertically-sliding plate located relatively to the point of severance of the clay bar, as shown and described, the rocklength, the bracket, the spring, and the disk having the elevations and depressions, all constructed and adapted to operate substantially as and for the purpose set forth.

6. In a brick-machine of the class mentioned, the combination, with the rotating cut-off devices, of the sliding plate located with relation to the point of complete severance of the clay bar, as shown, the rock-lever, the rod, the disk having the elevations and depressions,andmeans for holding the free end of said rod in contact with the disk by a yielding force, substantially as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature this 19th day of June, A. D.
