TO ALL WHOM IT MAY CONCERN:

Be it known that I, DARIUS WELLNGTON,`of Boston, in the county of Suffolk, and State of Massachusetts, haveinvented an Improved Brick-Machine; and I do hereby declare that the following, taken in conneetion with the drawingswhich accompany and form part of this speoiieatiomis a description of my invention suliicient to enable those skilled in the art to practise it. i

My invention relates to an organization of mechanism for converting clay into bricks for burning, and the invention consists in the peculiar combination and arrangement of parts by which the crude' clay, after being divided and pulverized in a pug-mill, is fed from thence into a series of moulds, automatically and successively K v brought under and fed vfrom the mill, and is solidified in the moulds and ejected from them, the surface of the mould, after being filled, being passed under a cutter, which cuts off the clay in the mould from that above it, and then under a throat-piece, which presses the loose clay into any unfilled parts of the mould, and then under a scraper, which smooths the surfaces of the bricks, and scrapes all projecting pieces or edges of clay from the mould.

The drawings represent a machine embodying my invention- A showing a side elevation, and A B a vertical longitudinal section of the same. y a denotes a strong bed, supported on a suitable frame, and extending nearly from end to end of the machine. Over thisbed is erected a pulveriaing-mill, b, in' which is a vertical rotary shaft, c, carrying a series of inclined blades, d, which, in their rotation, not onlydivido or break up the crude clay entered at the mouth of the mill,

but press it downwards towards the bed.

This shaft is supported i-n a bearing, e, on the framework above the bed a, and carries at its foot a bevelgearf, which meshes into and is driven by a bevel-pinion, g, on'the driving-shaft h.

At the lower part of the mill, a stationarywing, z',`stretchos across from the hub or bearing e to each side of themill, and the pulverized material pressed down by the blades dis stopped from further rotation by these wings, and collecting against them, is caught by the upper edge of a screw-blade, k, bounded by a ring or cylinder, l, this screw-blade, in its rotation, pressing the clay down against and into the moulds beneath.

The moulds m m traverse over the top surface of the bed a, and between suitable guides or ways, which keep the moulds' in position as' they slide over the bed. v i

The moulds tpinto a square opening, u, and drop through the same on to the bed a. In'rcar of this opening is a reciprocating plate or follower, o, the front end of which, as the follower goes back, comes under and flush with the rear wallp, allowing an empty mould to drop through the opening udown upon the bed.

' As the follower goes forward, it pushes tile mould before it, so as to carry said mould just from under the opening and sliding it from under the mould, resting upon it, which mould falls down upon the follower, and

-when the follower next goes back, falls down in front of it upon the bed a, its movement forward, by the next forward movement of the follower, carrying thc mould, inadvance of it, under the mill, where the rotation of the screw-blade fills it with clay.

The follower is attached to slides, g, on opposite sides of the machine, and these slides are connected by connecting-rods r to geared crank-wheels, s, meshing into and driven by a pinion-gear, t, on the driving-shaft. The shaft of the crank-wheel is so hung that when the connecting-rods are moving forward to advance the follower and moulds, they are in line with the slides q, and thereby prevent that strain upon the slides and follower which would takc place were the connection otherwise made.

The mould under the mill being filled, it is pressed forward by the empty mould next in rear of it, and as it moves on, it passes under a. scraper, t', which cuts the clay in the mould o from the mass vof clay above. This leaves the mould charged, except on its sides, where the clay may not ll out closely, or may be drawn back as the mould moves under the scraper. Ithereforo place an'inelined throat-piece, u, in front of the scraper, and as the loose clay above the mould hugs down under `this throat-piece, it is again compressed down snare 2 against the mould, and ii'lls all inter-sticos `left therein, an adjustable knife or .doctor, y, then trimming -oi allsurfaee clay as the mould passes under it.

The filled mould passes beyond the d octor, and is brought-to a state of rest (as the follower@ moves back) directly under a vertieallyreciprcating plunger or compresser-block, o. This block and a discharge-block orl piston, ze, are xed to the under surface of a platen, x, at the opposite ends of which are fixed slide-plates a', having vertical slots b', throughl which project guide-screws e.

To each plate aisjointed a. lever, dturnin'g on a fulerum, e', and'earrying at itsrear end a`pinf, pro. jecting into accom-groove, g', on the inner face of the gear-wheel 8,'the cam-groove being concentric with the axis of the gear, excepting in that part thereof acting upon thpin, while'the follower o is retreating and the moulds are at rest. i c

l As the follower rst begins to retreat, the cam forces the adjacentend ofthe lever up, and thereby depresses the `opposite end, earryingthe block e down into the lled mould beneath it, and compressing or solidifying the clay in the mouldfthe block being raised bythe continued aetionjof the cam as the follower completes its retreat.

The next forward movement of the follower carries the mould with the solidified clay underthe dischargeblock w, where it stops (as the follower retreats) while the discharger w descends. Thisrforward movement of the mould carries it'beyond the bed clover ,which it has. previously slid through all its intermittent movements) on t side rails 7L', leaving the mould open at its under surface. The discharged plunger then descends, and

ejects the clay from the mould in the form of av smooth,compaet, solid brick, the bricks falling upon an eud' less apron, i', by which they may be conveyed to any desirable locality for drying. l

The next forward movement of the moulds pushes oif the empty mould, which is then returned to the mouth or opening n to bc refilled. i l

The mechanism organized substantially as shown, .may be vused in the conversion of peat into portable blocks for fuel, as well as for the manufacture of bricks. i

` I claim, in combination with the follower, (which intermittently feeds forward the series of moulds,) and with the rotating pulverizing-blsdcs d and feed-screw c, (which break up the clay and force it into the moulds,)

I the scraper-bart', the throat-piece u, and the doctor y, each arranged to operate substantially as set forth.

Also, in combination with the reducing and feeding-mill b, and with the mould-feeding mechanism, the solidifying-plungerv, and expelling-plunger w, when arranged to operate substantially as described.

' Also, the arrangement of" the bevel-gcarf, at the bottom of the pulverizing aud'mould-iilling mill 6, to be driven by'a pinion, g, on the driving-shaft, just above the bed a, substantially as described.

Also, the arrangement ofthe crank and cam-wheel s, connecting-rod r, slides q, lever d', and slide-plates a', for driving the follower o and pluugers e w, substantially as described.

' DARIUS WELLINGTON.
