SPECIFICATION forming part of Letters Patent No. 482,808, dated September 20, 1892.

Application iiled November 30, 1891. Serial No. 413,546. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, JOHN R. MCGORON, a citizen of the United States, residing at Terrace Park,in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Stovepipe-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures ot reference marked thereon, which form a part of this specification.

This invention relates to improvements in stovepipe-fasteners, and has for its object to provide new and improved means to hold the stovepipe in place on said fastener, a portion of this latter being used to form a part of these means, whereby simplicity of construction, savingof material,` and a consequent reduction of the manufacturing costs are attained.

The construction of my invention is explained in the following specification and pointed out in the concluding claim, as well as illustrated in the accompanying drawings, in which- Figure 1 shows in a side or top view the device as it appears before it is put in position. Fig. 2 shows the same in a central vertical longitudinal section while being put in position. Fig. 3 shows an elevation of the inner end as it appears after the device is put in position. Fig. 4 shows the outer end under the same conditions. Fig. 5 shows in a partly-sectioned side elevation the device in position and the stovepipe connected to it.

6 represents a ue or chimney, and 7 the receiving-opening therein.

S is the elbow and upper part of a suitable stovepipe leading up from below.

The stovepipe fastener consists, substantially, of a piece of pipe9 of.suitable length, having the customary ornamental collar or iiange 10, which in this case is rigidly affixed to it, so as to prevent the pipe from sliding too far into the opening in theltlue.

To prevent the device from' falling outwardly, another flange 11 at the interior end of pipe 9 is provided. The distance between these two flanges corresponds with the thickness of wall 12 of the flue and by this construction holds the Whole device immovably in place. The upper end of the stovepipe or elbow, whatever the case may be, is held in place bybeing clamped in between the extending portion of pipe 9, as shown in Fig. 5. This outer end of pipe 9 is partly open, as shown at 13, and provided with upturned edges 14 15. A th umh-screw 16 passes through these edges and has its end provided with collars 17 17, located to either side of edge 14, whereby this latter and the screw are confined on each other in such a way that this screw is free to rotate,but not capable of any independent longitudinal movement. A nut 18 is rigidly connected to the opposite edge 15, through which the screw-threaded shank of screw 16 passes. Such a nut is required in order to increase the thickness of the metal sufficiently to permit a screw-thread to be cut into it, which otherwise could not very well be done with unreinforced sheet-iron. The effect of this construction is that when the screw is rotated in the proper direction, after the stovepipe has been introduced, edge 15, with nut 18, through which the screw passes, is advanced by this latter toward the other edge, drawing, also, the end of pipe 9 together until it impinges against the inserted end of the stovepipe and holds the same tightly in place.

The articleis intended to be manufactured and put on sale in the shape as illustrated in Fig. 1-that is, having one end provided with splits 19, which are of such a length that the uncut part of pipe 9 between the inner ends of these cuts and collar 10 corresponds with the thickness of the flue-wall through which the said pipe is to pass. The device is put in place as most plainly shown in Fig. 2. It is introduced into the opening 7 of the chimneyuntil iiange 10 comes fiat against the wall, after which the inner portion, extended beyond said wall and into the flue, is bent outwardly against the inside of the flue, the cuts in the end of the pipe making such procedure possible. After this the stovepipe is introduced into the outer end of pipe 9 and clamped tight, as already explained.

The construction and manner of holding the stovepipefastener in position on the chimney does not form a part of my invention, which latter has no constructive connection ICO with it and,in` fact, may be used on other faseners secured to the chimney in a dierent manner. In combining, however, my improvement to a fastener which I consider the cheapest and best as far as its construction and manner of connection to the chimney are concerned the sale of this particular fastener, as well as of my improvement, when combined therewith, is greatly enhanced.

Having described my invention, 1 claim as new- A stoVepipe-fastener having means to hold it in position in the chimney and being provided with the improved means to hold the stovepipe to it, which means are obtained by cutting a longitudinal slit in the fastener, and consisting of two vertical flanges which are formed by bending outwardly the cut edges of such slit, a reinforcing-nut connected to one of said flanges, and an adjusting-screw zo passing through this nut and connected to the other flange in a manner to prevent it from moving longitudinally, all as substantially shown and described.

In testimony WhereofI afx mysgnature in 2 5 presence of two witnesses.
