SPECIFICATION forming part of Letters Patent No. 254,314. dated February 28, 1882.
( Model.)
To all whom may concern Beitknown that I, CHARLES S. HEMPSTEAD, of Masontown, in the county of Fayette and State'of Pennsylvania, have invented a new and useful Improvement in Cowls, of which the following is a full, clear, and exact description.
The object of the invention is to support a reversible cowl over a chimney by means substantiallyas described and claimed hereinafter.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure l isa sectional elevation of my improved cowl, taken on the line 00 x of Fig. 2. Fig. 2is a sectional elevation taken on the line y y of Fig. 1.
A represents the vane, B the cowl proper, and C the chimney-cap, which has an" mental outline, and is formed with the ci collar 0 and the right-angled flanges b and b, the fiangebbeing adapted to rest upon the top of the chimney, the flange I) being adapted to surround the chimney on the outside, as shown in the drawings. Secured to the under sideof the flange b by means of the bolts a a is the downwardly-bent bar D, which extends down into theschimney when the cowl is in place, and secured upon the horizontal portion 6 of this bar, by means of the screw cl, is the horizontal cross-bar E, which is formed with the upturned endsi i, through whichthe set-screws ff pass.
Upon the upper side of the flange b, and secured by the same bolts, 01 a, which secure the ends of the bar D,is placed the upwardlybent bar F, which is perforated in the center and forms the journal'of the vertical spindle H.
The lower end of this spindle is pointed and rests in a socket formed in the upper end of the bolt d, and the upper end of the spindle extends a short distance above the collar 0 of the chimney-cap, where it is reduced in size and forms the pivot for the vane-arm g. Upon the vane-arm g is placed the collar J, which surrounds the collar 0, as shown, and turns with the vane. The cowl B ismounted on the upper edge of the collar J, and is secured thereto by the clasped or rolled joint on in such manner that the cowl is adapted to be turned upon the collar for setting the cowl so that its opening will be toward or from the vane, as desired.
Upon the inside, of the chimney are placed the plates h h, (shown in Fig. 2,) against which the points of the set-screwsfj' are turned for securing the cowl in and upon the chimney.
Having thus described myinventioml claim as new and desire to secure by Letters Patent 1. The combination, with the collar 0, having flanges b I) to hold it to the top of chimney, of the bars D F, provided with end flanges secured by boltsato opposite sides of the flanges b, as shown and described.
2. The cross-piece E and the barD, secured. together by the socketed screw cl, in combination with the spindle H, cross-bar F, and the vane-arm, substantially as and for the purposes set forth.
3. In combination with the cross-bar D, carrying the cross-piece E, provided with the setscrews ff, the plates h 11, substantially as and for the purposes set forth.
