STOVEPIPE-PROTECTOR.

Q Application led December 2, 1904. Serial No. 235,193.

T0 all whom, it may concern:

Be it known that I, SHERMAN BRUCE GRA- HAM, a citizen of the United States, and a resident of Corsicana, in the county of Navarro and State of Texas, have invented a new and Improved Stovepipe-Protector, of which the following is a full, clear, and exact descript1on.

This invention relates to stovepipe connections; and its object is to prevent the descent of products of condensation on the outside of a stovepipe.

The invention is especially applicable where the stovepipe is vertical and is more necessary under these circumstances.

Reference is to be had to the accompanying drawings, vforming a part of this specification, in which similar characters of reference indicate corresponding parts in both the igures.

Figure l is a perspective of my invention, showing the same in connection with a stovepipe, (represented in dotted lines;) and Fig. 2 is a vertical central section through my invention and contiguous parts as applied in practice.

Referring more particularly to the parts, 1 represents a vertical iiue, which is supposed A to pass vertically through a ceiling 2 and preferably to have a projecting extremity 3 lying belowlthe ceiling, as indicated. This flue l may be of iron, brick, terra-cotta, or similar material. To the projecting extremity 3 I apply a pipe connection 4, most clearly shown in Fig. l. This pipe connection comprises a centrally-disposed tubular thimble 5, preferably formed of stovepiping,A near the lower portion of which an annular collar `6 is attached, said collar being concave on its upper face, so as to constitute substantially a cup. The upper edge of the collar is adapted to be set against the ceiling, as shown, and the lower portion of the collar is preferably bent so as to form a downwardly-projecting mouth, which is received within the upper extremity of the sleeve 9, as indicated. From this arrangement it follows that deposits collecting in the collar will gravitate toward the sleeve and thimble. At the point at which this collar attaches to the thimble said thimble is 'preferably provided with an annular bead or recess 7, which extends completely around the same and which is formed by pressing the material outwardly, as shown. Through this bead or recess openings 8 are formed, which open communication between the space inclosed by the collar and the interior of the thimble. Below the collar and thimble a sleeve 9 is provided, which is, like the thimble l5, of tubular form, as shown, both of these received in the upper mouth of a vertical A stovepipe 10.

As indicated most clearly in Fig. 2, the

thimble 5 is thrust upwardly into the interior of the ue l and affords means for centering the pipe connection and preventing its lateral displacement.

From the arrangement described and illustrated evidently any products of combustion, such as creosote, which form upon the inner surface of the iue and which gravitate toward the projecting extremity 3 cannot find their way to the outer side of the pipe connections. If any such products sh'ould pass downwardly on the outer side of the thimble, they will pass into the space inclosed by the collar 6 and will eventually pass through the openings 8, referred to above, finding their way into the interior of the sleeve 9 and the pipe l0.

While the invention is intended especially to prevent the descent of products of com bustion on the outer sides of the pipe connections, it also operates benecially to prevent rainwater from passing down in like manner.

While I prefer to construct the device of separate pieces in the manner described, in practice I may form certain of the parts integrally or otherwise, as may seem best, for evidently the benefits of the invention depend upon the form of the complete device and not upon the minute details of its construction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A stovepipe connection comprising a thimble adapted to be inserted in a flue at a ceiling, a cup-shaped collar liaring upwardly and attached to said thimble, the upper edge whereof seats against said ceiling, said thimble having a plurality of openings therethrough adjacent to the bottom of said collar through which a substance may pass from said collar.

2. A stovepipe connection comprising a thimble adapted to be inserted at the base of a stack or chimney, a concave collar adapted to collect drippings coming down said thimble, and a sleeve below said collar, the interior whereof is in open communication therewith to pass said drippings from said collar into said sleeve.

3. A stovepipe connection, comprising a centrally-disposed Substantially tubular thimble having a circumferential bead formed in the wall thereof, with openings through said bead, a cup shaped annular collar formed about said thimble and connecting therewith below said openings, and a substantially tubular sleeve projecting below said collar and adapted to be received within a vertical stovepipe, said collar affording means for return ing drippings to the interior of said sleeve.

4. In combination, a substantially Vertically-disposed iue, the lower extremity whereof projects below a ceiling, a tbim ble received within said projecting extremity of said ilue
