\ lllieffprocess of.V forming. bricks by `provedymodelis as follows.` `The -clay isztemp,ered;..by any-of the usual,` millsor. mixersl andi: discharged 0r=` shoveled,4intoa wheel barrow or otherl` conveyance inwhich ity is.` co-nveyedgto ,thez yard, and Vdeposited upon the hard surface prepared -for. its reception between f the. parallel guides a, placed `at the, u distance of. 18` or 27 inches,(ori the lengthlofz` two or three brick apart). These lguidesur.,l arel about eightor teny feetlong,' and of the thickness, of a y brick, their ends have, slits.

. a', cui'J them"through` `which metal-wedges `pass to the ground, serving; tokeepj the` guides in line. andfasten them'uto the yard; thexcross guides. b, give the requisiteldistance to :be preserved lbetween `the rguides a'.

Before laying. dow-n the guides a, lwet their irneryedges andfsprinkle@ them with sand to` prevent the?L adhesion of the mortar, ythough `ifffa-ny` such l` adhesion takes place, afthin` knife "passed 4between the: guide4 and edge ofthebed will readily insure separation. .y Atfter the s mortar. A is f depositedv between ther guidesqa, `as above described it isv spread-.out land smoothed over the top by the scraper or! lute B, whichto prevent adhesionis occasion'allyjdipped in Waterl onsand.` Afterl `iillingethe space between the guides 4@and smoothing the upper surface, byy means of the,` scraper ior'lute. B, the. guides a, `are removed, and `rthere remains on 4the yard a bed. offmortar the thicknessiof "a brick, `and in Width vequal Ito two` `or three times: thelength of 3a bricklaccording to the` distance.. apart of theguides a. The gage Gr, sho-wnin Figs.y 2, "and 3,"is then placed over the bedqwith the interiorface d, against one of the longitudinal edges of the bed, then the blades of the cutter H, shown in Figs. 4 and 5, are inserted in 'the slits f, in the top of the gage, and drawn through them, dividing the bed in `the lines m,'m, of Fig. 11. This operation is repeated until the whole bed is formed into sections containing each twoor three bricks, as seen in Fig. 11, the gage being moved longitudinally as the operator finishes the portion of the bed beneath it. This movement may be facilitated by 4constructing on gage G, wheels and handles, so that said gage' may be rolled along the bed as required for the operation. Instead of the cutter H, there may be used a series of knives or cutters secured perpendicular to a board, and otherwise so arranged as to pass simultaneously through the slits f, of the bed D, into the bricks E. The bed D, is

then suffered to remain where formed until the clay in drying causes a separation along all the lines m, m, and n, ln., dividing the bed into separate and distinct bricks. The edging tool shown in Figs.k 13, and 14, is then inserted in the transverse lines m, m, and the bricks raised on edge as seen in Fig. 12. This tool is nothing more than a piece of board with a projecting sheet iron,

' .or other metallic blade g, as seen in Figs.

13 and 14. The bricks are now in a rough condition, and for the purpose of bringing them into a condition suitable for facing brick, I pass the tool P shown in Figs.

4"15 and 16, over the upper edges of the row of bricks when placed as seen in Fig. 12. This tool has a smooth metallic surface c, equal in width to the thickness of a brick, bounded on one side by the flat plated,

- vand on the other by theknife 71, both perpendicular as to the surface c. The surface c, as the tool is drawn toward the operator compresses and smoothes the edge of the brick, while the plate d, and knife z', sharpen the edges and trim off any superfluous thickness of the brick. The ends of the brick may be smoothed in the same way if it be so desired. After pressing and polishing the upper edge of each row of bricks as above f described, they are allowed to remain until sufliciently dry to remove for burning. In lthis manner with but few attendants, may4 be formed with the utmostrapidity bricks that will be equal in quality to any produced by the ordinary process of molding, and equally as durable for all building purposes. Having thus described my improved mode of manufacturing bricks, I wish it to be understood that I make no claim to any portion of the processes of manufacturing bricks set forth in the French patents of Capgras, and Chanon, June 21st, 1843, and Charles Henry Maigret, May 22d, 1840, But What I do claim as new and of my own invention, and desire to secure by Letters Patent is:

The manufacture of bricks substantially as above described; that is to say by first spreading the tempered mortar or clay at once upon the ground where the bricks will be left to dry and in beds of certain desired length, width and thickness, and then while the mortar is in a soft state, or before it shall crack by too much drying, producing therein lines of weakening or separation dening the dimensions of the bricks without regard to their smoothness or final finish; and after the bricks in drying shall have separated from each other along the lines thus formed, turning them on edge, and squaring and polishing their edges and dening the thickness of the same by rubbing over them the metallic tool P or otherwise substantially as set forth; the desired thickness of the bed being produced by means of guide bars or molds and scraper or lute substantially as specified, whereby I am enabled to dispense with of bearers, and otherwise to simplify the manufacture of bricks.

In testimony whereof I have hereunto signed my name before two subscribing wit,

nesses.
