SPECIFICATION formingpart of Letters Patent No. 309,037, dated December 9, 1884.

Application filed April 10, 1884. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES A. TARRAGON, of Portland, in the county of Multnomah and State of Oregon, have invented anew and useful Improvementin Brick-Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a sectional rear elevation of my improved machine. Fig. 2, Sheet 1, is a side elevation of the same, parts being broken away. Fig. 3, Sheet 2, is a plan view of the same, partly in section, through the line 00 00, Fig. 1. Fig. at, Sheet 2, is a plan view of the grate, the shaft being shown in section. Fig. 5, Sheet 2, is a sectional plan view of the machine, taken through the line yy, Fig. 1. Fig. 6, Sheet 2, is a front eleva tion of the lower part of the machine.

The object of this invention is to provide a simple, effective, and convenient machine for making bricks.

The invention consists in a briclemachine constructed with a vertical shaft placed in a vertical hollow cylinder, and provided with radial arms carrying teeth to break up the clay, and plates to force the clay through a grate secured in and to the said cylinder, whereby the clay will be crushed as it passes down into the machine. WVith the lower parts of the cylinder and shaft are connected a hollow grinding-cylinder having a tapered and corrugated inner surface, a cylinder having spiral corrugations and radial wings, substantially as herein shown and described, whereby the clay is crushed and ground as it passes down through the machine. end of the shaft, within a recess in the base of the machine, are attached curved wings to push the clay out throughopenings in the said base at the opposite sides of its recess. In the ends of the base of the machine, opposite the side openings to the recess, are formed chambers, in which move carriages carrying molds hinged to rods attached to the ends of the said carriages and held erect by springs, so that the said molds can be readily brought into position to receive clay and withdrawn To the lower end of a crank-shaft, D, having a pulley, D,

upon its outer end, to receive adriving-belt driven from a steam-engine or other convenient power. v

To the inner end of the crank-shaft D is at tached a miter-gear wheel, ll, the teeth of which mesh into the teeth of the miter-gear wheel L, attached to the upper end of the vertical shaft G. The upper part of the shaft G revolves in bearings in the frame 0, and its lower end revolves in a bearing in the bottom of the recess H, formed in the upper middle part of the base A below the lower end of the hollow eylinder'B.

To the opposite sides of the vertical shaft G, at or a little below the top of the hollow cylinder B, are attached the inner ends of two radial arms, 1', which are made triangular in form, and are arranged with the correspond ing sides of the two arms in the same plane and with their lower sides horizontal.

To the forward parts of the horizontal lower sides of the arms I are attached one or more knives or teeth, J, which are inclined downward and forward.

To the rear inclined sides of the arms I are attached the upper ends of short bars K, to the lower ends of which are attached plates L of such a length as to leave spaces of about half an inch wide between their ends and the shaft G and the shell of the hollow cylinder B.

The bars K are'made of elastic material, so that the plates L, should they strike a lump of clay or other hard substance that they cannot break, will yield and pass over the obstruction.

To the shell of the hollow cylinder B, just below the lower edges of the plates L, is secured a grate, M, formed of parallel bars connected at their ends by a rim fitting into the interior of the said cylinder B.

In the center of the grate M is formed a bearing, N, to receive the shaft G and keep the said shaft in position.

The clay is fed into the upper. end of the cylinder B through a spout, O, or by other suitable means, where it is worked .by the arms I, knives J, and plates L, and is forced by the said plates through the grate M, all lumps being broken up between the tops of the grate-bars and the said plates L.

In the lower part of the hollow cylinder B is secured a hollow cylinder, 1?, the interior of which is tapered downward or made in the shape of an inverted truncated cone. The tapered inner surface of the hollow cylinder 1? is grooved, as shown in Fig. 5, to adapt it to grind the clay.

To the shaft G, in such a position as to be within the lower part of the grinding-cylinder 1, is secured a wheel or cylinder, Q,which is tapered downward or made in the form of an inverted truncated cone. The wheel or cylinder Q is made of such a size as to fit into the lower part of the grinding-cylinder I, and upon its face are formed spiral corrugations to adapt it to grind the clay and at the same time feed the clay downward.

To the shaft G, at the top of the grindingwheel or cylinder Q, is attached a conical hub, R, to which are attached radial wings S, the outer edges of which are tapered downward to correspond with the taper of the inner surface of the cylinder 1?, so that the clay will be broken up and fed downward between the outer edges of the said wings and the corrugated inner surface of the said cylinder.

To the lower end of the shaft G, within the recess H of the base A, are attached curved wings T, to push the clay as it falls into the recess H outward and force it through the openings U at the sides of the said recess II into the molds V. The molds V are placed edgewise with their open sides toward the openings U, and are hinged at their lower edges to rods \V, attached at their rear ends to carriages X. The carriages X and molds V are placed in passages a in the end parts of the base A, and have longitudinal grooves Y formed in the opposite sides of their lower parts to receive the guide cleats Z, attached to the opposite sides of the passages or chambers a. The carriages X are mounted upon wheels I) to cause them to move forward and back easily.

To the outer ends of the hinging-rod XV are attached the inner ends of the coiled springs c, the outer ends of which are attached to the outer ends of the molds V. The springs c are made of sufficient strength to raise the molds V, when left free, into an erect position. Vith this construction, as the filled molds come out of the chambers a, they are turned downward into a horizontal position, as shown at the right-hand part of Fig. 6, and discharge the bricks upon offbearing -boards, ready to be taken to the drying-yard. The outer ends of the molds V are provided with handles (Z, for convenience in controlling them.

To the rear ends of the carriagesX are pivoted the forward ends of the connecting-bars e, the rear ends of which are pivoted to the lever f, upon the opposite sides of and equally distant from the pivoting-point of the said lever. The lever f is pivoted. to a bar, '5, attached to the base A or other suitable support, and one end of the said lever f is extended, and to it is pivoted the end of a short connecting-bar, g, the other end of which is pivoted to the lower end of the lever h. The lever h is pivoted to a bar, 9', attached to the standard k, which is attached to the base-A or other suitable support.

To the upper end of the lever 71 is pivoted the end of a short connecting-bar, Z, the other end of whiclris pivoted to the crank D of the crank-shaft D, so that the carriages X will be operated by the revolution of the crank-shaft D to carry the filled molds V outward alternately to discharge the bricks and draw them inward to be again filled. The carriages X have plates m attached to their inner sides, to close the openings U and prevent the clay from being forced into the passages a while the filled molds are being carried out, emptied, and returned to the said openings U. I

The guard-plates m may be provided with friction-wheels to roll along the outer sides of the passages a and strengthen the said guardplate against the outward pressure of the clay.

The machinery may be provided with wheels, so that it can be readily moved from pit to pit.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a brick-machine, the combination, with the vertical shaft G and its driving mechanism, and the vertical hollow cylinder B, of the arms I, downwardlyprojecting teeth J, and downwardly-inclined plates L, and grate M, substantially as herein shown and described, whereby the lumps of clay will be crushed as they pass down into the machine, as set forth;
