ELIJAH MYRIOK, OF HARVARD, MASSACHUSETTS.

CHIMNEY-CAP.

Specification forming part of Letters Patent No. 90,380, dated May 25, 1869.

To all whom it may concern:

Be it known that I, ELIJAH MYRICK, of Harvard, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Ghimney- Gaps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

It is well known that the upper courses of brick in commonly-constructed chimneys are liable to become loose by the action of the Weather upon the mortar, and the top bricks are liable to get out of place and be blown off by the wind. To overcome this diificulty castiron caps, made of one piece, have been used to some extent; but the objection to the extensive use of such caps has been found in getting caps to fit the various sizes and forms of chimneys, and such caps are heavy and difticult to place onchimneys with commonly-constructed staging; also, requiring the manufacturer to make a large outlay for many patterns also, requiring him to keep on hand a large amount of castings to fit any considerable number of the various sizes and forms of chimneys, thus rendering the general sale of such caps by country traders impracticable.

To avoid the above objections is the object of my invention.

The nature of my invention consists in constructing cast-iron or metal chimney-caps in sections or divisions, in such a manner that the same patterns may be used, and the castings therefrom will answer for all the varioussized chimneys.

In the accompanying drawings, Figure 1 is a perspective view of a chimney with metal cap constructed in sections. Fig. 2 is a top View of a cap, showing the connections that hold the cap together. Fig. 3 is a side View of the chimney-cap, showing the difi'erent parts or sections of the cap. Fig. 4 is a side view of a single angle section or division of the cap. Fig. 5 is a top view of an anglesection, showing the method of connecting it with the next section. Fig. 6 is a top view of a straight section, showing the method of connecting it with the next section. Fig. 7 is a cross-sectional view through the line a: 3 Figs. 2 and 5, showing the seat for the brick and the outer and inner flanges of the cap that hold the cap in place when placed in po sition on the top of a chimney.

Like letters represent like parts in all the figures.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a chimney-cap in straight and angled sections.

In the accompanying drawings, A A are angled sections. B B are straight sections. Each of these sections is constructed with flanges h and I, Fig. 7, lips C, Fig. 5, and D, Fig. 6, and recesses E F, which are provided with starts to fit into seats in lips D and G. (Shown in Figs. 2, 5, and 6.)

The angled sections I construct all of the same length, of sufiicient size to cover the top of about an eight-inch-flue chimney.

I construct the straight sections of different lengths-viz, the width of a brick, or about four inches, and the length of abriclnorabout eight inches.

These sections are constructed to fit into and connect with each other and with the angled sections, and all are held in position by the lips O D, starts and flanges h and I, projecting downward on the inside and outside of the chimney.

It will be readily seen that by this method of constructing chimney-caps of separate sections any desirable-sized chimney-cap may be made for either square or oblong chimney, and may be readily placed on the top of any chimney without extra assistance and from the same scaffolding employed to build the chimney.

They may be all cast from one set of patterns, and may be kept on sale at a low price at any country store, and become an article of commerce, like window-weights, glass, or nails, and thus be brought into general use.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A chimney-cap, when constructed of separate sections, held in position by means of flanges, substantially as described.

2. A chimney-cap, constructed in sections, held together by means of lips, recesses, and starts, substantially as described and set forth.
