2 Claims. (Cl. 285-39) This invention relates to a iixture for stove pipe and the like and more particularly to a combination tlue reducer, flue stop, pipe collar and pipe reducer.

The principal object of the present invention is to provide a novel stove pipe iixture havinga plurality of uses. More specifically, it is an object to provide a iixture which may be used alternately as a flue reducer, flue stop, pipe collar or pipe reducer.

Another object is to provide a durable, neat and economical multi-use xture that may be easily, but positively, adapted for any of the stated uses or other uses suggested thereby.

These and other objects will become apparent hereinafter.

Briefly, the invention comprises a fixture including a sleeve member adapted to engage a pipe or ilue opening, a radial collar about the sleeve member and provided with a sealing edge at its outer periphery, and a plurality of inserts nested with the sleeve member and each other and having predetermined diameters adapted to receive stove pipes of different size, the center insert being a plug for altering the xture from a flue or pipe reducer to a ue stop.

The invention also consists in the parts and in the combination and arrangements of parts hereinafter described and claimed.

In the accompanying drawings which form a part of this specification and wherein like numerals refer to like parts wherever they occur,

Fig. l is an exploded side elevational view, partly in section, of the parts of a fixture embodying the teachings of the present invention,

Fig. 2 is a front elevational view showing the parts of the fixture in assembled relationship,

Fig. 3 is a sectional view of the fixture taken substantially along line 3-3 of Fig. 2,

Fig. 4 is a greatly enlarged sectional view taken along line 4 4 of Fig. 2, but typical of the locking means between the other parts of the fixture also, and

Fig. 5 is a view similar to Fig. 4, but showing a modiiication of the fixture.

Referring to Fig. l of the drawings, a fixture constructed in accordance with the teachings of the present invention comprises a sleeve member 11; a collar or ange member 12 adapted to t over the sleeve member 11; large and small insert rings 13 and 14, and an insert plug 15 which are adapted to be removably interlocked with the sleeve member 11 and each other to form a ue stop, as will become apparent hereinafter.

The sleeve member 11 includes a sleeve body portion 16 having a crimped and tapered edge 17 for insertion Within a ue opening or straight stove pipe section (not shown). An annular outwardly-extending radial bead 18 is formed on the other edge 19 of the sleeve body 16 and a radial inwardly-extending ange 20 is integrally connected thereto. The sleeve member 11 is also provided with an annular axial wall 21 detining a central opening 22, the axial wall 21 being attached to the inner edge of the radial tlange 20 in concentric spaced relation with the sleeve body 16 and extending to a free or unattached edge 21. The diameter of the central opening 22 is predetermined so that the insert ring 13 or a stove pipe (not shown) may be positioned therein.

The collar 12 is provided with a central opening 24 defined by an annular axial wall 25, the opening 24 having a predetermined diameter adapted to receive the sleeve body 16 of the sleeve member 11 therethrough. The axial wall 25 is attached to the inner edge of a radial flange 26 having a sealing lip 27 formed on its outer edge. The flange 26 is also formed into an annular depression 23, which provides a second sealing lip or bead 29 positioned in the same radial plane as the sealing lip 27. When the collar 12 is positioned about the sleeve member 11 (Fig. 3), the axial wall 25 is snugly tit on the outer periphery of the sleeve body 16 and the inner edge of the radial flange 26 is abutting the annular bead 18 of the sleeve member 11.

The large insert ring 13 is channel-shaped and comprises a radial wall 31 having an annularbead 32 formed about its outer periphery, an axial side wall 33 attached to its inner periphery and defining a central opening 34, and an axial flange 35 attached to the bead 32 in concentric spaced relation with the side wall 33. The side wall 33 extends in an axial direction to a free or unattached edge 33. The axial ilange 35 is provided with an outwardly ilared free edge 36, the distance from the flared edge 36 to the bead 32 being greater than the length of the axial wall 21 of the sleeve member 11 so that when the insert ring 13 is positioned in its central opening 22, the ilared edge 36 will overlap the unattached edge 21 of the axial wall 21 and provide a positive interlock between the insert ring 13 and the sleeve member 11, as shown in Fig. 4. The annular bead 32 is thus positioned in abutting relationship with the radial flange 20 of the sleeve member 11 adjacent to the axial wall 21.

yAs shown best in Figs. l and 3, the radial ange 20 of the sleeve member 11 and the radial Wall of the insert ring 13 taper slightly inwardly so that the annular beads 18 and 32 are positioned in aprpoximately the same radial plane when the insert ring 13 and sleeve member 11 are nested together in interlocked position. The insert ring 13 is also provided with a lip 37 formed on the outer periphery of the annular bead 32. When the insert ring 13 is secured to the sleeve member 11, the lip 37 is spaced from the radial wall 20 to provide a slot so that a suitable tool may be inserted therein for removing the insert ring 13 from the sleeve member.

The small insert ring 14 is similar to the insert ring 13 and comprises .a radial wall 39 having an annular bead 40 on its outer periphery, an axial wall 41 attached to the inner periphery of the wall 39 and having a free edge 41', a central opening 42 formed in the radial wall 39, and an axial flange 43 attached to the bead 40 and having a ared edge 44 on its unattached end. The insert ring 14 may be retained within the insert ring 13 in the same manner as above described, and a lip 45 is provided on the bead 40 so that the insert ring 14 may be removed therefrom.

The insert plug 15 is also provided with an axial ilange 47 having a ilared edge 48 adapted to interlock the plug 15 with the ring 14. The iiange 4'7 is .attached to an annular bead 49 having a tool receiving lip 50 thereon, the bead 49 being formed on the outer periphery of a radial disc or plate Si. Therefore, when the insert plug 15 and the insert rings 14 and 13 are nested with the sleeve member 11 and the collar 12 is positioned thereabout, a sealed unit is provided which may be used as a llue stop. Inasmuch as most flue openings have an inside diameter of six inches, the sleeve body 16 is preferably provided with a slightly larger outside diameter to assure a tight t therebetween. When the sleeve body 16 has been inserted into a flue opening (not shown), the sealing lips 27 and 29 of the collar 12 will be positioned in abutting relation with the wall `(not shown) adjacent thereto.A As previously seen, the inserts 13, 14 and 15 are frictionally and sealably fitted in the sleeve member 11 so that soot or dirt will be prevented 'from filtering into the room through the flue stop or between the collar 12 and the wall.

When it is desired to connect a stove pipe (not shown) to the flue, the insert having an outside diameter corresponding `to the size of the stove pipe is removed from the fiue stop and the stove pipe is inserted in the opening thus provided. inasmuch as stove pipes are commonly made up .in standard three, four, five or six inch siZes-the insert rings 14 and 13, the sleeve member 11 and the collar 12 are provided with central openings 42, 34, 22 and 24 adapted to respectively accommodate the different sizes of pipe, It is obvious that if a six inch pipe is used, it may be inserted directly into the flue opening and the collar 12 may be positioned thereabout to prevent any infiltration of soot into the room from between the pipe and the flue opening.

It is now apparent that the fixture may be used as a flue reducer for connecting either three, four or five inch pipe to the six inch sleeve member 11, or a six inch pipe ydirectly to the flue with the collar 12 providing a sealing flange thereabout. Furthermore, by removingy the collar 12 the xture 10 may be employed as a pipe reducer for interconnecting a three, four or five inch pipe with a six inch pipe in the same manner as just described.

It is to be understood that the foregoing description and the accompanying drawings have been given only by way of illustration and example, and that changes and alterations in the present disclosure, which will be readily apparent to all skilled in the art, are contemplated as within the scope of the invention. For instance, although concentrically nested insert rings have been disclosed, they may be eccentrically positioned if so desired. Furthermore, it is within the scope of this invention to form the rings in shapes other than circular. Also each of the raised tool receiving lips 37, 45 and 50 formed in the parts as shown in Fig. 1 may be formed as a 2,991,448 y Y f depression or slot 37', 45', or 50' in the adjacent part, as best shown in Fig. 5 for the Idepression 37' which is typical.
