HENRY T. CLAY, OF GARDINER, MAINE.

SHINGLE.

Specification of Letters Patent No. 22,350, dated December 21, 1858.

To all w/wm it may concern: A

Be it known that I, HENRY T. CLAY, of Gardiner, in the county of Kennebec and State of lvIaine, have invented a new and Improved Shingle for the Covering oi' Buildings; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of ret'- erence marked thereon.

The nature of the invention consists in the peculiar shape of the shingle, it being so constructed that a portion of the shingle at the butt, (consisting of such portion as is laid or exposed to the weather, which is -generally about one third of the length on the upper side, as from Z) to c and a perfeet straight surface on the under side as from a to c. In making a shingle thus, it gives more thickness at the point Z) where the layerneXt above begins, and thus gives a longer wear to it by the abrasion of rain, and snow, than can be had by the shingle made in the common form.

`What I claim as my invention, and for which I ask an exclusive right isl. A shingle of uniform thickness at the butt, so far as it is to be laid to the weather.

2. A shingle that commences to taper at the point on the upper side, where the next layer' above covers it, and tapers all on that side,
