. To all whom t may concern: The machine B has a suitable main frame Be it known that we, JOHN TV. AREGOOD I, a cutter-frame J, a carrier K, a receivingand GEORGE H.

The main frame I has its legs l provided This invention i's an improvement in that with suitable guides c' for the upright bars j class of brick-machines wherein the clay is of the cutter-frame J. On the top frame we 6o ro formed into a long slab or slabs fed along a support'bearings N for the rollers O of the carrier, then cut into brick lengths, and then several belts P, which constitute the carrier fed off the carrier; and the present invention K.

Now this is of especial ciples of our invention, the purpose being to importance, as in forcing the slabs of clay roo. 5o reciprocate the rod F by the turning of the across the carrier the belts may move with it master-wheel. independently of the sprocket-Wheels, so that the said belts will in a measure serve as rollers upon which the slabs move forward, so that instead of the slabs being forced along the belts and become rucked up by friction therewith t-he belts are moved forward by the slabs of cla)7 and so serve as rollers for the clay as t-he latter moves forward to position upon the carrier. The particular form of clutch shown includes ratchet-disks 1, fixed 0n the shafts O', and the ratchet-disks 2, xed to the sprocket-wheels and normally in contact with the disk 1. The operation of said mechanism will be fully understood from the foregoing description in connection with the drawings.

At the rear end of the machine the carrier delivers the cut bricks to a discharge-belt M, o which they may be taken by hand. This belt is passed around guide- rollers 3, 4, and 5 and a drive-drum 6 on a shaft 7. This shaft 7 also has a pinion Sand a bevel-gear 9. The pinion S meshes a gear-wheel 10, which in turn meshes a pinion l1 on one of the rollers O, usually the rear one of such rollers, as shown. The bevel-gear 9 is meshed bya pinion 12 on a shaft 13, to which is fixed a'clutchsection 14. A clutch-section 15 is movable into and out. of engagement with the clutchsection 14, and is supported on ashaft 1G, hav ing fixed and loose pulleys 17 and 1S, which may receive a drive-belt from any suitable drive-shaft.

The clutch-section 15 is moved into and out of clutch with the section 14 by means of the crank-arm 19 on the rock-shaft 20, such crankarm being connected by rods or links 21 with the clutch-section 15, so that the rocking of the shaft 2O moves the clutch-section into and out of engagement with the section 14, in order that the shaft 13 and the parts geared therewith may be driven at certain intervals in the operation of the machine, as will be further explained hereinafter. This shaft 2O and a similar shaft 22 have cranlcarms 23, to which the slide-rod F connects, and they are also provided with crank-arms 24, connected by links 25 with the uprightsj of the' cutterframe. It will be seen, therefore, that the longitudinal movement of the rod effects the vertical movement of the cutter-frame and also the movement of the parts necessary to adjust the connections between the driveshaft 16 and the shaft 13, as before described.

The cutter-frame is provided with the cutterbows 2G, which are spring-metal plates secured between their ends to the top bar of the frame J and adapted at their ends to receive the wires 27, which are held taut by the tension of the bows, such tension resulting in the construction shown, from the resiliency of the spring-plates and the supplemental springs 28. The springs 2S are supported on a rod 29, extended between and through the arms of the bow, provided outside said arms with heads or nuts 30 and between their ends with nuts 31, the springs 28 bearing between the nuts 31 and the arms of the bow, so that the tension of said springs may be regulated by adjusting-nuts 31, as will be readily understood. The spring-bow operates as a spring or yielding support for the cutting-wires 27, which are of considerable importance, inasm uch as it avoids the breaking of the wires. In case they should come in contact with a stone or other unyielding` body in the clay the wires will yield and not be broken, as would result if they were stretched in an unyielding support. To enable the convenient application of wires to the bows, we provide compressing devices for forcibly bringing the ends of the bows nearer together. In lthe construction shown the compressing device includes a lever 32, which fulcrums between one of the heads 30 and the side arm of the bow arranged at its lower end to bear against the said arm and having its upper or handle end provided with a detent-pawl 33, engaging a ratchet 3l. Then it is desired to applya wire to the bow, the lever 32 may be pressed out at its upper end. This will force the ends of the bow inward toward each other, in which position they will be held by the ratchet and pawl while the wire is being applied, when the pawl may be released and the bow will expand and hold the wire taut.

In practice we make the belts P of clear i gum, so that they may be fitted tightly on their rollers and will not be inj uriously affected by the moisture in the clay.

It will be understood that in practice we prefer to arrange machines B, on opposite sides of the pug-mill and operate the latter to force slabs of clay alternately to the said machines.

The slabs forced from the pugmill pass across the heated table L onto the carrier, the belts of which are moved by the moving clay and render the forward movement thereof easier, as will be readily understood. Then the slab has been forced onto the table, the master-wheel will have been revolved to such extent as to bring its cam to such position as to force the slide-rod forward. This movement of the slide-rod operates through the rock-shafts and their crank-arms and connections to lower the cutting-frame, forcing the wires through the clay and below the same into the grooves q, and then move the clutchsection to cause the gearing to operate to advance the carriers and feed the cut bricksout of the machine.

IOO

It will be seen that the cutting-wires do not move upward through the cuts made by them in the clay, and so give the ends of the bricks a ragged appearance; but after forming a clean cut through the slabs the wires remain in the grooves q until the bricks are fed off the machine. After the carrier has been operated to feed the bricks olf, the cam of the master-wheel will operate the slide-rod to lift the cutter-frame and adjust the clutch-sections apart, when slabs of clay will again be forced onto the carrier, and the operation proceeds, as before.

Having thus described our invention, what we claim as new is- 1. A machine substantially as described having its carrier composed of a plurality of carrier-belts of lengths approximating that of bricks, the said carrier-belts being powerdriven independently of the movement of the clay, whereby the cut bricks may be discharged from said belts by the power applied to the belts, substantially as set forth.
