Improvement in Stove Pipe Thinibles.

i Ion OEPHAS A. BUTTLES OF MILWAUKEE WISCONSIN.
IMPROVEMENT IN STOVE-PIPE THIIV'IBLES.
Specification forming part of Letters Pateiit No. 120,710, dated November 7, 1871.
To all whom it may concern:
Be it known that I, GEPHAs'A. BUTTLES, of the city and county of Milwaukee and State of Wisconsin, have invented an Improved Stove- Pipe Thimble; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which Figure l is a plan view; Fig.2, a bottom view; Fig. 3, a vertical section in line 00 x of Fig. 1; Fig. 4, a detached segment of the upper ring, showing, in perspective, the strengthening ribs on its under side; and Fig. 5 represents a segment of the lower ring, showing one way in which the rabbet may be made.
Similar letters of reference in the accompanying drawing denote the same parts.
This invention relates to that class of stovepipe thimbles for which Letters Patent of the United States were granted to me October 12, 1869; and consists, first, in an improvedmeth- 0d of constructing the heads for the purpose of holding the inner band more securely, and also of protecting its edges; secondly, in a method of strengthening the upper head so that it can be made very light without danger of fracture; and thirdly, in an improved method of attaching and staying the outer hand without the employment of the annular flanges heretofore generally employed for the purpose.
In the drawing, A represents the upper and B the lower head, of cast-iron, connected by the sheet-metal band 0 and inner band D. Both heads are cast with a groove, 6, around their inner edge, into which the edges of the band D that embrace the faces of the plates are pressed so as to lie closely in the grooves, below the level of the rest of the plate, whereby they are protected from catching into anything, while, at the same time, they hold the band in place much more securely. From its situation in the floor of the upper apartments of a house the head A, during the summer season when the stove-pipe is removed, is liable to be broken by the weight of people stepping upon it. 7 Greater strength is therefore needed in this plate than in the lower head B, and, accordingly, I construct it with a series of ribs, a a a, cast on its under side in lines radiating from the center of the thimble. These ribs need extend no further outward than the band C, for the reason that outside of said band the plate is supported by the floor; in fact,- they could not extend further, because it is necessary that the plate should rest flat upon the floor.
The pressure of the strengthening ribs dispenses with the necessity for the flange to support the band, as heretofore, and enables me to make the plate much lighter and, at the same time, much stronger.
The peculiar shape of the concave lower plate B enables me also to dispense with any flange on that plate, the band C resting directly against the convex surface of the metal near its outer edge, or against a square shoulder in the plate formed by making a kind of rabbet around its lower edge, as clearly shown in Fig. 3. This plate can, therefore, be made very light as well as the upper plate.
Having thus described my invention, what I claim as new therein isp 1. Securing the inner band of a stove-pipe thimble by binding its edge over into grooves e 0 formed in the outer surfaces of the heads, substantially as and for the purposes described.
2. The radial ribs to a cast in the upper plate A of a stove-pipe thimble, substantially as and for the purposes herein set forth.
3. -A stove-pipe thimble constructed with upper head strengthened by ribs a a and lower head formed convex on its upper side, said heads being connected by a sheet-metal band,'0, held by the ribs of the upper and convexity or rabbet of the lower head, and also by a short metal band, D, having its edges turned over the inner edges of the heads, substantially as and for the pur poses specified.
