Letters Patent No. 113,847, dated April 18, 1871 antedated April 8, 1871.

IMPROVEMENT IN MACHINES FOR MAKING BRICKS AND TILES.

The Schedule referred to in these Letters Patent and making pari: of the same.

this specification, in which- Sheet 1 Figure l represents a longitudinal section of the machine for making bricks and drain-pipes. y Figure 2 is a front elevation and view of the same. Figure 3 represents the month-piece and mold for ,the pipe and collar.

Sheet 2- Figure 4 represents a longitudinal section of the front part of the machine, showing the mouth-piece and cut-off of the bricks or drain-pipes.

Figure 5 is a side elevation of the vertically-operating knife and cut-ofi' of the bricks and pipes.

Figure 6 represents a longitudinal section of the mouth-piece, showing the mold for the bricks and pipes.

Figure 7 is a front view of the brickemold.-

Figure 8 exhibits a longitudinal section and front view ofthe mold for making the drain-pipes.

The nature of my invention consists in theJ arrangement and combination of a double-danged screw in front, a single-flanged screw in the rear, (on thesame shatr't,) with oblique cutters operating around the rear screw, but in opposite direction, and iced-rollers above the knives; also, the shape and construction of the mouth-piece, forming and molding the collar with the pipe at the same operation, with the dovetail piece sliding on the brick-mold and the mouth-pieces ofthe pipe-molds sliding in dovetail guides in front of the dovetail plate; also, the construction of the knife or cutter operating'in a reciprocating motion, by which the bricks and pipes are eut olf at the mouth-of the machine with accuracy and facility; also, the movable Acylinders surrounding the double screw, that is attached by a bayouet-1ock so as to be easily removed and a larger or smaller cylinder attached to the headplate of the machine sc as to mold large or small pipes; also, a revolving core in front ci' the double screw.

The object of my invention is to manufacture bricks or draimpipes by one machine, tempering its own clay, and enabling meto manufactnie terra-cotta pipe and common drain-pipe with thevsame facility, the double screw giving increased pressure uponl the clay, while the collar is molded at the same time with the pipe.

To enable others skilled in the art to make and use my inventiomI will proceed to describe its construction and operation, asfollows:

A represents the upright frame or iron plates that support the devices.

B represents thehopper at top,in which the clay is put. l

G, the cylinder or lower part of the hopper that the rollers D, knives E, and screw F operate in.

The rollers D D are operated by toothed wheels 'Gr G at the end. The pinion H that is geared into one of the toothed wheels, G, drives the two oblique knives, I I, that are attached to a circular plate, J, at one end and a ring, K, at the other end, the knives working independently of the main axis L, a'nd in an opposite direction from the single-flanged screw M, so that there is a free passage for the clay.

The front end of the axis L operates in an upright support or post, N, as a bearing, which bearing is between the single-flanged screw M and the doubleflanged movable screw P in front. p

In front of the double-flanged screw P is the core Q that is screwed into the end of the main shaft L infront of the screw P, and this core forms the inside oi' the pipe and its collar.

The outside of the core R, as shown atiig. 3, is made in two halves, with abuckle'or fastening, S, at top, and au adjustable rght-and-leit hand screw, T, below, for the purpose of freeing the pipe and collar when molded. This mold It also slides to either side in a slotgU, be-

llow, suliciently to clear the pipe,aud is held securely on each hall' by two pins, V V, ou the outer cylinder W, the .cylinderW bcing'movable and attached to the front of the hopper@ by a bayonet-joint, X.

`The mouth-piece `Y for making bricks lits onto the front of the cylinder W also by a bayonet-joint, and

the plate Zl that holds the molds Z'LZL forV making" pipes is fitted by a dovetail to the front of the inouth-- piece Y, as shown at gs. 6 and 8. The molds for making pipes Z2 Z" lit into the .plate Zl in a dovetail, the plate Zl being made ot' metal and with dovetails on the front and back sides so as to be movable when required,and the plate has twoor more apertinr'es, ac-

cordingito the number of molds to be used for making two or more pipes at the same time.

The knife a that cuts oli` the brick or pipe as it passes from the mouth of the machine is a horizontal knife at the lower side of .a square upright frame, b, that is attached to a cross horizontal pitman, c, that has a reciprocating motion, the pitman c being attached to cranks (l d of the toothed wheels e e that give the pitman a lateral, upward, and downward movement; and the knife a being permanent] y fastened to the center of the pitman O, receives its lateral, upward, and downward motion, and as it descends in a perpendicular line to ont olf the brick or pipe passing from the mouth-piece, it moves with the pipe, cutting it perfectly straight at each downward ont.

The knife is operated by band-wheel, f, and belt, moving regularly with the band-wheel and belt that drive the machine. p

The center-wheel g, as shown at iig. 5, is to give the same motion to wheels e e. The knife a operates at right angles with the month oi' the machine.

h andj represent a table and apron, intended to be used for carrying oithe bricks 'and pipes when molded.

As the clay is passed through the hopper B it is carried, between the horizontal rollers D D,to the tem.
