CHIMNEY-CAP.

Specification of Letters Patent.

Patented Feb. 24., 1914..

Application filed April 12, 1913. Serial No. 760,679.

To all whom it may concern Be it known that 1, WILLIAM L. CARTER, a citizen of the United States, residing at Waterloo, in the county of Blackhawk and State of Iowa, have invented a new and useful Chimney-Cap, of which the following is a specification.

The invention relates to improvements in chimney caps.

The objectof the present invention is to improve the construction of chimney caps, and to provide a sectional chimney cap, capable of ready adjustment to fit chimneys and bricks of diiferent sizes and adapted to be arranged flat upon the top of an ordinary chimney and having spaced inner and outer walls and forming an intervening space for the reception of mortar, cement, grout, and the like, whereby a solid top is formed and the cap securely retained in position on a chimney.

A further object of the invention is to provide a chimney cap of this character equipped with sections constructed to prog vide rigid joints, whereby the sect-ions are effectually prevented from twisting or otherwise getting out of proper position with relation to one another.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a perspective view of a chimney cap, constructed in accordance with this invention and shown applied to a chimney. Fig. 2 is a plan view of the chimney cap. Fig. 3 is a central vertical longitudinal sectional view of the chimney cap. Fig. 4 is a transverse sectional view of the same. Fig. 5 is a detail horizontal sectional view, illustrating the manner of adjusting the inner walls. Fig. 6 is a detail perspective view of one of the corner sec tions. Fig. 7 is a detail view of one of the outer side plates.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the chimney cap, which is designed to be constructed of cast metal or other suitable material, is of approximately rectangular form and comprises in its construction corner sections 1, outer side and

end plates

2 and 3, and inner side and end plates 4: and 5. Each corner section consists of an outer corner portion 6, an inner corner portion 7, and an integral diagonally arranged horizontally disposed brace 8, connecting the inner and outer corner portions and located at the bottom of the chimney cap. The diagonal brace is preferably flanged, as shown, being composed of a vertical longitudinal web or flange and opposite horizontal bottom fianges, the bottom flanges being arranged in flush relation with the lower faces of the outer corner portions and adapted to rest upon the top of the brickwork of a chimney 9.

Each outer corner portion 6 is composed of two sides or wings, arranged at rightangles at the top or upper edges of the corner portion and curved downwardly and in wardly from the upper edges and presenting outer convex faces. The curved sides or wings of the outer corner portions are connected by the curved side and end plates, which are fitted against the inner faces of the sides or wings, being adjustably secured tothe same by bolts 10, piercing the sides or wings and arranged in longitudinal slots 11 of the curved side plates. The bolts are provided at their outer ends with heads and have nuts at their inner ends, and when they are tightened the similarly curved sides or wings and the outer plates are drawn tightly together and a rigid sectional outer wall is thereby formed by the said parts, which are efi'ectually prevented by such construction from becoming twisted out of proper position. The outer corner portions are provided at their upper edges with interior grooves 12, formed by oilsetting the said upper edges and receiving longitudinal upper flanges 13 of the curved angles to each other, and are adjust-ably connected by the side and

end plates

4 and 5, which are also straight. The side and end plates, which are fitted against the inner faces of the sides or wings of the inner corner portions, are provided with longitudinal' slots 15 through which pass bolts 16, which pierce the sides or wings of the corner portions. The inner side and end plates and the inner corner portions form an inner sectional wall, which is slightly higher than theouter wall, and'the said inner wall defines a central rectangular opening to register with the flue or passage of the chimney. The inner side and end plates are provided at their lower edges with longitudinal flanges 17 extending outwardly beneath and fitting against the lower edges'ofthe sides or wings of the inner corner portions, and adapted'to prevent the sections of the inner wall of the chimney cap from twisting on each other.

The inner and outer walls of the chimney cap form an intervening rectangular space around the central opening, and the said space is-open at the bottom betweenthe diagonal braces of the corner sections 1, so that when the chimney cap is placednpon the top of a chimney and the said intervening space filled with mortar, concrete, grout,-or other suitable plastic material,'such filling will form a solid top for the chimney and will adhere to the brickwork and securely retain the chimney cap thereon. The chimney cap,which walls such plastic filling at both the interior and exterior of the chimney, will prevent the samefrom breaking down even though the cement top portion should crack. The curved sections or portions of the outer wall ofthe chimney cap besides operating to form a tight joint when clamped together also present a neat ornamental exterior appearance and provide an attractive finish to the chimney.

What is claimed.is:--

1. A chimney cap adapted to be placed upon the top of a chimney andcomposed of inner and outer walls spaced apart, the inner walls defining a central opening to register with the passage or flue of the chimney and the outer walls conforming to the contour of the chimney, said chimney cap being open at the top to enable a plastic filling to be supplied to the intervening space between the said walls, and braces disposed in substantially diagonal positions and connecting the inner and outer walls at the corners thereof and arranged at the bottom of the cap and adapted to rest upon the top of a chimney.

2. A chimney cap including corner sections composed of inner and outer corner portions connected with each other and having angularly related sides or wings, and inner and outer plates or sections connect-ing the corner portions and forming spaced inner and outer walls.

3. A chimney cap including corner sections composed of inner and outer corner portions having angularly related sides or wings and diagonally disposed braces connecting the inner and outer corner portions and arranged at the bottom of the chimney cap in position to rest upon the top 01": a chimney, and inner and outer plates or sec tions secured to the sides or wings of the inner and outer corner portions and forming spaced inner and outer walls.

4. A chimney cap including corner sections composed of inner and outer corner portions, the inner corner portions having straight angularly related sides or wings and the outer corner portions being provided with curved sides or wings, outer curved plates or sections secured to the sides or wings of the outer corner portions, and inner straight plates or sections secured to the sides or wings ofthe inner corner portions.

5. A chimney cap including corner sections having inner and outer corner portions, the outer corner portion being provided with angularly related sides or wings curved downwardly from their upper edges and provided thereat with grooves, curved plates or sections secured to the sides or wings of the outer corner portions at the inner faces thereof and provided with flanges fitting in the said grooves, and inner plates or sections connecting the inner corner portions. 7

6. A chimney cap including corner sections composed of inner and outer corner portions having angnlarly related sides or wings, the outer corner portions being'provided at their upper edges with grooves, outer plates or sections secured to the sides or wings of the outer corner portions and having upper and lower longitudinal flanges to embrace the same, the upper flanges fitting the said grooves, and plates or sections secured to the sides or wings of the inner corner portions.

7. A chimney cap including corner sections composed of spaced inner and outer corner portions having angularly related sides or wings, inner and outer side and end plates having longitudinal slots and In testimony, that I claim the foregoing provided also with longitudinal flanges to as my own, I have hereto aflixed my signafit against the said sides or Wings, and fasl ture in the presence of two Witnesses. tening devices piercing the sides or Wings 1 WILLIAM L.
