UNITED STATES PATENT ALBERT SCHMALL, OF NEW YORK, N. Y.
CHININEY TOP AND COWL.
SPECIFICATION forming part of Letters Patent No. 531,750, dated January 1, 1895.
Application led March 3, 1894. Serial No. 502,174. (No model.)
To all whom t may concern.-
Be it known that I, ALBERT SCHMALL, a resident of New York, in the county and State of New York, have invented a new and useful Improvement in Chimney Tops and Cowls, of which the following is a specification.
My invention relates to an improvement in chimney tops and cowls in which provision is made for securing the support for a rotary cowl in the top of a pipe or chimney in such a manner that it may be removed and replaced at pleasure without interfering with the integrity of the pipe or chimney and without requiring the removal of any portion of the pipe or chimney;
A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l represents a chimney top and rotary cowl in position therein, the view being taken in vertical section, and Fig. 2 is a transverse section through the chimney top and removable cowl support.
A represents the chimney top or pipe, which may be ot terra cotta or other earthen material, or it may be of galvanized iron or other met-al. The pipe is provided with lugs a on its exterior for the attachment thereto of guy wires for holding the pipe in position. On its interior it is provided with grooves of, arranged diametrically opposite and adapted to receive therein the tongues d2 on the outer edges of a sliding frame B. The sliding frame B consists of a top cross piece h and bottom cross iece h and two sides connectin Y the' ends of the top and bottom cross pieces. The top cross piece is provided with au opening h2 centrally therein for the reception of the cowl spindle C and the bottom cross piece B is provided. with a socket piece h3 for the reception of the lower end of the spindle C.
The rotary cowl, which may be of any well known or approved form, is denoted by D and is provided with an interior cross piece CZ and with a socket piece d at its upper end for the reception of the spindle C.
The cowl maybe secured to the spindle, ai-
ter being placed thereon, by means of a pin d2 inserted through the spindle above the cross piece d and, if found desirable, the spindle maybe locked in the frame B by inserting a pin c through the spindle beneath the top cross piece l).
The parte may be adjusted by simply inserting the spindle in the frame Beither before or after the insertion of the frame B into the top of the chimney and, if it is so, attached to the frame B before the latter is slid into the chimney, the only operation required is to simply slide the frame B down into the grooves iu the top of the chimney and then lock the cowl D to the spindle. its support may be removed at any time by simply sliding the frame B out of the chimney when the latter will be left open and free to be cleaned from sootl or otherwise operated upon, as may be required.
To prevent the spindle from wearing the cowl or the cowl support away at the points which bear upon the end of the spindle or upon which the spindle bears,l employ steps or bearing pieces of glass, hard en ed metal, o1l other suitable hardened material, as shown at m, Fig. 1.
Vhile I have shown several different forms which the removable cowl support may assume, it is obvious that further slight changes might be resorted to in the form and arrangement of the several parts Without departing from the spirit and scope of my invention. Hence I do not Wish to limit myself strictly to the structure herein set forth, but
What I claim is- The combination with the chimney top provided with grooves located on its interior and a cowl, of a cowl support having tongues at its periphery adapted to slide along the grooves on the interior of the chimney top, andl a spindle engaged with the cowl support and cowl, substantially as set forth.
ALBERT SUI-IMALL.
