Be it known that I, VVILLis'B'NEHEmQa citizen of the United'States of America, residing at Decatur, in the county of Mor gun and State of Alabama, havezinvented' 1 usual-and customarylongitudinal parallel certain new and useful Improvements in Apparatus for the Manufacture 'o f Rou'gh- Texture Brick, of which the following is a specification.

' My invention relatesto an apparatuspan ticularly intended for the productionot a novel type of rough texturebrick ,in accordance With-the processforming the subject "matter' ot a companion application filed of even date herewith, Serizil'lloJTfiQl, which brickis characterized byhaving its face provided with irregular flattened relief patches that give it a pleasing variable 1mto that of rotten stone. 7 V

"for proviclin'g the longitudinal scoreson one or more faces of the brick column in, comv bination With means, however operated, for.

transversely scoring the'top scored surface of the column and means 'to roll such sun' face to flatten the raised portlons andbond the displaced patches to thecolumn. It is to be understood that the mechanism,

which is hereinafter described in 'detail and' -Wlllcll is illustrated in its preferred embodiment only intl e accompanylng drawings,

The shaft 115 carriesv fast. thereon a bevelled gear 19 whichi meshes with a? bevelled gear 20 on" a shaft .21 at right; angles to .the' shaft '15 v and mounted in anelongated hearingQQ .on'the I On the overhung end of the shaft 21I mount a crahkcliskfEZS having 35 pin 24. to which a connecting rod 25 is coupled at one end, its othen end being con nected' between the lugs 26" on the frame of. v a reciprocating carriage 27 supported on eafchvside two pair of rollers 28 whi'ehl 7 travel between horizontaltracks '29 formed bylspacedconnected bars disposed transversely of andabove the scored .columna. The tracks are mounted on brackets of depending below it and attached to, its sides I a U-bar' 31 parallel with the column l'and having depending from' its under face a series of adjustable screws'32pointed at 'their lower ends and adapted to transversely scorefthe longitudinally scored top surface secured in the; plate; The u'pper tra ckibars' are cross braeed ve head the flat-bar at one and by tliti'r'ched bar at the; end near the crank disk; 7

It will be noted that the carriage will move with very little friction in its guide tracks and that the transverse scoring of the column face does not interpose a heavy duty on the drive which would cause a slippage of the column 4: on the measuring belt '6. This enables me to utilize the movement of the column to apply the transverse scoring thereto so that it will be uniform.

To the right of the cross scoring mechanism I mount journal brackets 36 in which I pivot the arms 37 which in their free ends are adapted to receive the axis 38 of a roller 39 which is adapted to rest on and to roll flat the raised portions left by the intersecting scores on the top surface of the column. This roller has the usual fabric cover it) to give a rough texture surface to the pertions which are rolled fiat in relief relative to the main body of the column. Beyond the roller the finished column passes to the cutting reel, not shown, but which in the usual manner will subdivide the column into bricks having their faces with the rug texture finish which is produced by-my process in the top surface of the column.

While I have shown and prefer to use a mechanical drive for the transverse scoring which is co-ordinated with the movement of the column, nevertheless my invention contemplates in its broadest aspects the combination of mechanisms, however operated, which will produce upon any desired surface of the column, intersecting diagonal scorings and mechanism for rolling the resultant irregular surface.

In operation, as the clay column 4; is expelled from the die 1, the scoring devices 2 and 3 will apply to the top and side surfaces of the column longitudinal scorings 5 in the usual manner, and the column thus scored will pass onto and by its weight will drive the measuring belt 6. From this bolt, through its forward idler 8 and the transmission mechanism described, the carriage 2'? will be reciprocated back and forth with a travel which will cause its scrapers 32 to traverse the full width of the top face of the column except about a quarter of an inch along each side to avoid injury to the corners of the column. Due to the factthat the transverse scoring takes place cotempo raneously with the longitudinal movement of the column, these scorings are diagonal and not at right angles to the longitudinal scorings 5. As the scoring points pass transversely across the ridges left by the scorings 5, they tear away and displace sections of such ridges, leaving the main body portion of the column exposed and displacing the ridge section on the face of the column. In this way the surface of the double scored face is not only broken into patches by the intersecting scorings, but raised portions thereof are entirely displaced in a manner which is immethodical and variable. l v hen the raised portions are rolled a vfinished surface is produced formed by flattened high faces of irregular outline and of variable position which rise in relief above the main body surface of the column and give a surface or texture quite similar to rotten stone.

I prefer a roller 39 as the most suitable means for finishing the double scored face of the column because it is necessary to apply enough pressure to the detached portions of the top surface to obtain a satisfactory bond with the main body portion of the column and a roller is the most suitable and practical means to attain this end, though any smoothing means might produce an approximate effect.

Though I have described witi great particularity the details of the embodiment of the invention herein shown, it is not to be construed that I am. limited thereto, as changes in arrangement and substitution of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is r 1. In a brick machine, mechanism for longitudinally scoring a column of brick material, a mechanism for transversely scoring a longitudinally scorer. face of the column, and presser mechanism to flatten down the doubly scored face of the column.

2. In a brick machine, in combination with mechanism for producing a longitudinally scored brick column, of mechanism for transversely scoring and means for rolling the doubly scored surface of the column.

In a brick machine, the combination with mechanism for producing a longitudinally scored brick column, of mechanism coordinated with the movement of the column to transversely score it, and means to smooth the do bly scored surface of the column.

l. In a brick machine, a. cutting table for a brick column con'iprising a measuring belt, mechanism for delivering a. brick column onto said belt to drive it, means to longitudinally score the column, means to transversely score the column, means to drive said latter means from the belt, and means to roll the transversely scored surf-ace of the top.

In testimony whereof I ture.
