IMPROVED BRICK-MACHINE.-

cro'ALL WHQMIT MAY coNcnRN:

Be it known that I, `DAVID SMITH, of Newburyport, in the county o-frEssex, and State of Massachusetts, have invented certain Improvements in Brick-MachineSg and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.

With reference to the drawings Figure 1 represents a perspective view of a machine, showing `my improvements, a portion of the framework, 850.', being broken away, the better to show the workingparts, and a portion of the cylindrical case of the grinding and moulding-portion of the machine being removed 'to show the parts within.

`Figure 2 shows the arrangement of the moulds, so as to have a clear space above for the material to he pressed'directlydownward into them as well as outward radially, as shown in iig'. 1.

Figure 3 shows a sand-ease, arranged over the moulds Z, so that after being lled, the moulds pass through sand with` the moulded brick, so that the exposed parts become sanded to prevent sticking in the press, Sto.

. 4The three gear-wheels a b e serve to give movement to the various ,operative parts through their respective shafts d ef. The driving-power may be applied to .shaft drthrough the gear a, or otherwise, to ycause it to revolve with its attached arms Zij kVandso drive the gears b c and their shafts ef. Or either of the shafts ef may be made lthe driver, if preferred. v 4

Around shaft oZis the case g, into 'which the material for bricks is put.V The arms Zz grind and stir the same, Aand by their inclined or screw-shape press the material downward through a stationary perforated plate or grating, z'. This'grating insures the passing of the material with a suicient degree of nencss to the arms j lc, which further stirand reduce it toda proper consistency for moulding.

The' arms j lc are attached to and revolve with the shaft d.

Just outside of arms jZc-s arranged an annular series oi` brick-moulds, Z, open at top and sides. Into these moulds Z the material is pressed by the arms j 7c, the partj of which is in screw-blade form or angular, form topress downward ,into moulds Z, while the part/c has a spiral or curved eccentric form, and operates at the same time to press the material outward into the moulds Z, more perfectly when they arrive in succession at the side shown-in the foreground of the drawing and opposite to the presses hereinafter alluded to.

Thea'nnular series of moulds Z forms a larger circle than the case for4 grinding up and pressing the material Vinto the moulds, so'that in their revolution they pass at one point entirely outside of the case or to au open space afforded for the operation of the presses, hereinafter described.

The series of moulds Z has an intermittent movement, each period f which correspondsto or measures thedistance from centre 'to centre of the adjacent moulds.

And each mould, after being filled, stops in succession at a point opposite to that where the arms j Zt press `closest to thermoulds.v 'A series of presses, m o, also arranged and moving in a circular track, has a correspending intermittent movement, and each press m o in the series stops in its movement'directly against one of the moulds Z, also at rest, at the same instant.

Atthis same moment the follower n has a movement from a point within the track of moulds' l, toward one of the presses m, moving the moulded brick thereby from the mould into the press, and properly pressing'it with the same movement. ,A l

.The mouldsZ and presses then pass along in the direction of the arrows to the next point of rest and coincidence, and a cam, within the series of presses m o, acts on the movable back o of thevpress and forces the new-formed and pressed brick,p, outgof the pr'ess; then, it rests on a rim or table, g, fromwhich it may be taken by hand or an endless belt, or otherrautomatic carriage or stationary table may be arranged instead to receive the brick as it leaves thepress. l i l The movable back o is pressed hack again by theintroductiou of the next brick, at a point where the cam, which throws it ou t, is inoperative. The series of moulds Z receives its Vmovement from the. cranks of shafts e andf through pawls r s.

The-'series of" presses, or m o, the movable parts, receives'its, rotary intermittent movement from the series of moulds Z, by means of the gears tand u connected to the series of moulds Z, and the series of presses, these. kwheels t and u playing into cach other.

` The arm v serves to give the follower n a movement up and down in the slide w, and this movement keeps the material scraped off, that otherwise might adhere and accumulate, 'so as to give roughness to the brick, and allows it to pass over the brick inward, preparatory to the pressing operation.

The slide w is operated with a reciprocating intermittent movement, so as, by the follower n, to move` the i moulded brick from the mould into the press m, and press it by meansof a pin and slot, 5, in lever e, and the of presses m o, constructed. and operating substantially as described.

rods 2 and 3 embracing cranks on shaftf, and which operate said lever s.

The lever v receives its movement from the' crank :v of the shaft c, which it embraces and operates follower n through the crank-arms y.

The sand-case 4, iig. 3, furnishes sand to the surface of the moulded bricks as they pass toward the press. l

The sand thus applied to the surface tends to prevent the brick from adhering too tenaeiously to the press. The machinery may be made of iron entire, or the same, or other metals combined with wood, accordingto the convenience or facilities of the maker.-

'lhus having described my improvements, what I claim as my invention, and desire to secure by Letters Patent, is as follows:

` Claims.

2. The intermittent rotary series of presses m o, constructed and operating in combinationA with the follower n, substantially as described. q I f '3. The combination and arrangement of the annular series of moulds Z, and the intermittent rotary series Witnesses:
