WILLIAM BARRY, OF NEW HAVEN, CONNECTICUT.

ROOF.

SPECIFICATION forming part of Letters Patent No. 247,596, dated September 27, 1881.

Application filed March 23, 1881.

To all whom it may concern Be it known that I, WILLIAM BARRY, of

New Haven, in the county of New Haven and IO ing the side inclined stones or material of the roof, near their upper ends, each with two inclined grooves meeting attheir lower pointsof inclination about midway the width of the stone or material, and having thereat an out- 1 5 let, all arranged under theridge stone or piece,

substantially ashereinafter more t'ullysetforth 151d claimed.

In the accompanyingdrawings, Figure I is a perspective view, showing my improvement 20 at the right of thejoint, and Figs. 2, 3, 4, and

5 are details and a section of the joint.

To enable others skilled in the art to which my improvement appertains to make and use the same, I will describe it.

A indicates a stone formingapart of the roof of a vault. One-half of its overlapping parta is cut away in such a manner that the overlapping surface is inclined, and so that the cut surfaces form an acute angle. In the inclined overlapping part the groove 00 is cut.

B represents another stone forming a part of the roof, and has one half of its overlapping part I) cut away in such a manner that the overlapping surface is inclined, and so that the cut surfaces make an acute angle. These overlapping parts 06 and I) fit together, andthe surfaces of the stones form an even surface. In the upper part of the stones are out the (No model.)

grooves m it. Two of these grooves are made in each stone and inclined downward,meeting at their lower points of inclination about midway the width of the stone, where they are provided with an outlet, as at m, for draining OK the water received into the grooves or gutters m n, dripping into the latter between the joints of the ridge piece or pieces.

A groove, 0, uniting theinclined grooves or gutters at a point above their conjunction, may

be provided for aiding drainage, if desired; but it is not essential.

The stones C, Figs. 1 and 2, form the ridge of the vault, fit on the stones formingthe sides of the roof, and are united by joints made after the {orm of joint uniting the inclined side pieces. The aforesaid form of joint is old, its function, as is well understood, being to drain any water passing down between the stones into the acute angles, which will run it ofl, and to carry ofi' by the grooves a any water rising by capillary attraction or driven up by the wind. I therefore lay no claim to such construction.

I claim and desire to secure by Letters Patent- In a root, the inclined side stones or pieces having near their upper ends and under the ridge stone or piece each two inclined grooves or gutters, m a, meeting at their lower "points of inclination and provided thereat with an outlet, m, substantially as and for the purpose set fort-h.

WILLIAM BARRY.
