WILLIAM J. KAYSER AND CHAR-LES KAYSEH, OF MILWAUKEE, IVISGONSIN.

CHIMNEY CAP AND VENTILATOR.

SPECIFICATION forming part of Letters Patent N0. 320,794, dated June 23, 1885.

Application filed May 27, 1884.

To all whom it may concern:

Be it known that we, WILLIAM J. KAYSER and CHARLES KAYSER, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Chimney-Gaps and Ventilators; and we do hereby declare that the fol lowing is a full, clear, and exact description thereof.

Our invention relates to improvements in chimney caps and ventilators, and will be fully described hereinafter.

In the drawings, Figure 1 is an elevation of a chimney-pipe fitted with our improved cap and ventilator. Fig. 2 is a vertical section through the center of the same, and Fig. 3 shows the fastenings of our device.

A is the chimney-pipe, which is fastened in any suitable manner on top of the chimney A.

B is a truncated open cone set in an inverted position around the pipe A, and attached thereon, so that its upper half projects above the top of said pipe, while an annular space, a, is left between its lower rim and the periphery of the pipe A.

B is'another open truncated cone set in its upright position around the pipe A, above and opposite the cone B, the distance between the two said cones B and B being about equal to half the height of the former.

The two cones B B are connected to one another, and are supported around the pipe by means of the supportingpieces O 0, one of which is shown in perspective in Fig. 3. The edges of these supportingpieces G are shaped in a manner to conform to the inclined surfaces of the cones B B and to the sides of the pipe A, and are provided with flanges c, c, and o The flange 0, formed on the lower half of the vertical inner edge of each of the supporting-pieces O, has about two-thirds of its length bolted or riveted to the pipe, while the upper part of the same is cut and bent out to form the hook c and clasp the top of the pipe A, as shown. The flange 0, formed on the lower-inclined edge of the supportingpiece 0, is riveted or bolted onto the inner face of the cone B, while the flange 0 formed (No model.)

on the upper inclined edge of said piece 0, is

riveted or bolted onto the inner face of the cone B. An open slot, 0, is cut into the vertical inner edges of said pieces 0 G, and in these slots, which are on a suitable incline, is inserted the lower rim of the shield E, made in the form of a truncated open cone. This shield is designed to prevent the deflection into the pipe A of the forced draft created in the space a left between the cones B and B.

Around the upper rim of the upper cone, B, are fastened the upright pieces (Z (Z d, which serve to support the pipe-cap D, made in any suitable form and with its outer rim projecting sufliciently outward beyond the upper edge of the cone B to protect the top of the pipe A from return drafts as well as from rain or snow.

Though we have described our cap and ventilator as being formed with cones, it'mnst be understood that the same may be made either square or with any number of sides, and its dimensions and proportions may be varied as desired without departing in the least from the spirit of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a chimney cap and ventilator, the conibination of the upper and lower truncated cones with supporting-pieces 0, having slots 0, adapted to receive the edges of the shield, as described.

2. In a chimney cap and ventilator, the combination of the cones B and B, the supportingpicccs 0, having flanges c, c, and c, and open slot 0, and shield E, adapted to fit into theslotsv of the supporting-pieces, and cap D, with fast eningpieces (Z d, substantially as shown and described, and for the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
