First-Description of one of the plates designed to form part of a roof which may be detached without destroying theadjacent parts or plates having its upper' and lower edges rabbeted. A is the platecast of a quadrilateral form, plane on the upper side as at A, except its two upper edges which are cast with rabbets A2,`on the upper surface, and its two lower edges which are cast with rabbets A3 on the under side; and at A4 where the screw passes through which is raised on the upper side in the form of a circular protuberance or curb A4L having a countersink to admit the head o f the screw, and the necessary cement for protecting the screw from the weather. The center of the plate on the under side is cast concave at A5 between the thick portions thereof Ay which form the bearings which rest upon the laths or-sheathing. Thetwkof-corners]'at-A?? aref cast straightfand parallel, forming; ob-

See Figs. 1- 3-4 and 13.

B Fig. 9, yrepresents one of the triangular plates fitted against the division wall or fire guard. The base andperpendicular of this plate are made like the two corresponding sides ofthe plate above described. The

hypotenuse or long side, which is fitted against, the fire wall, is made straight and plain` having a bearing to rest on the laths and being secured by letting the long side into a corresponding groove in the fire wall and heldsecurely bythe lap of the plates, and by cement. C, Fig. 8 is atriangular vplate arranged along the leaves. The plate is cast in thexsame form as plateA B Fig. 9, f-

vexcept that its long lside or hypotenuse which is placed parallel to the eaves is cast with a flange C nearly at right angles to the face vof the plate fitting over the eaves and conducting the water to the gutter, having the end ofeach flange cast with a notch C2 .to

correspond with the corner of the next ad# joiningplate fitted into said notch.

D, Fig. 6 is a 'triangular plate to be fitted against the comb of the roof. This plate is made in a similar manner to plate B Fig. 9, the long side or hypotenuse being placed parallel to and against the Vridge andthe two other sides which are rabbeted being fitted to the corresponding rabbeted sides 'ofthe adjoining plates-a screw being inserted in the manner above described. E, Fig. 1l isa sectional view of the cast-A ing thatcoversthe two upper edges of the plates that come nearly together at the ridge,

. or comb, cast in the shape of a saddle having a vertical flange E extending downward from the apex and arranged between the upper edges of said plates, being perforated for bolts or screws by which it is fastened to the ridge pole or other convenient place, and when properly secured effectually `secures the joint at the ridge against the entrance of water o r snow. f

The plates A are placed on thelaths in a position to bring the edges thereof at an angle of 45 degs. with the parallel lines of the eaves and ridge-or any required angle.`

The manner of uniting and securing the plates is more clearly seen at Fig. 13 which is a vertical section on theline e" a of Fig. 14.

F is the gutter secured in the cornice below the eaves the` anges of the triangular plate of the eaves extendingover the inner edges of the gutter.

. Having thus fully described the naar@ of my invention and improvement in cast .iron roong I proceed to state that what 35` I claim as my invention and desire to secure by Letters Patent' isl. Forming the rectangular plates A with rabbeted edges A2 A3 on opposite sides, flat on the upper side, or surface and concave on the nnder surface, having two of the corners A7 of each plate cut offl parallel causing the plates to combine and unite and form close joints, having broad bearings A6 to rest on the sheathing or laths, and a perforated protuberance, or lmob At, and a countersink in the same to admit the shank and head of a lscrew s back of the point of junction of the cut off corners A7 of the plates, so that when a plate is required to be removed it becomes only necessary to withdraw the screw s and slide the plate back from beneath the contiguous plates and it becomes separated therefrom asv before de- 3.' I also claim constructing the ridge cap E like an angular roof with a vertical plate E projecting down from the apex and perforated to admit bolts, or screws, by which it is secured to the ridge pole-the sloped `sides being made sufficiently wide to extend `over vthe adjoining plates on either side of the ridge asabove described and represented at E Figs. ii-ie--iawiaY y i MATHEW STEWART.
