The VSchedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, FRANCIS E. SCOTT, of Centreville, in the county of Wayne and State of Indiana, have invented a new and useful Improvement in Drain- -Tile; and I do hereby declare the following to bea full description thereof', reference being had to the accompanyingdrawing, iu which- Figure l is a view showing how different sections are united;

Figure 2 is a cross-section; and

Figure 3, a single brick.

My 'nvention relates to a method of forming draintile of three bricks in a section, by which advantages al'e'ohtained over the usual plan of vforming tile.-

With tile-brick designed for twobricks to the section, in order to give the channel the' proper size and form, it is necessary to make the concavity of the channel surface deep, and, unless the brick is made too large and heavy, it follows thatit is quite thin centrally, beiugtl1ns liable ,to warp in the process of making, and become useless, this objection being obviatedwith brick designed for three to the section.

yThe peculiarities .of form' of a .brick for a threebrick section .according to my invention, consist in a concave surface on one side of said brick, and grooves at cach side of' saidv concave surface, by which latter v theel-bricks are locked or held together.

,':The'grooves by which the brieks'are locked or held .together in forming 'a section,`.in the accompanying peach other 'in such a manner that the peculiarities of one 4groove or set of angles are adapted to the pecu- .liarities of the-opposite groove or set of angles in forming a section of'three bricks; hence each brick has the same peculiarities.

The bottom angle of the groove atc is a right angle.

` At b, the bottom angle is an acute angle..

The outer angle atc is adapted to the cavity of groove b, and the inner angle of groove b, which is a right angle, is adapted to the cavity of groove c.

Thus the out-er face of groove b overlaps the outside surface-o` the adjacent brick.

At `the side b of the brick a narrow space is left bef` tween the concave and the groove b, whichimakes a right angle of the inner angle of groove b.

The above-described manner of forming the section of tile so locks the bricks vtogether that a pressure at any point on the section serves to unite them more firmly, instead of Vspreading them apart.

The diiierent sections forming the continuous tile are united by alternate overlapping of' the bricks, as shown in iig. 1.

Having thus fully described my said invention,

What I claim, and desire to secure by Letters Pat ent, is-

lhe improved drain-tile herein shown, consisting of' the three concave sections 1 2 3, provided at their respective locking-edges with the grooves or channels formed as shown at l and c, and adapted and combineditogether-in the manner and for the purposes herein set forth. I l

' .FRANCIS E. SCOTT.
