CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 758510, dated April 26, 1904.

Application filed August 4, 1902.

T0 a/ZZ whom, it may concern: l V

Be it known that I, PAUL DicKINsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Chimneys, of which the' following is a specication.

My invention relates to an improvement in the class of adjustable chimneys; and my objects are to simplify the structureV by avoiding any elbow -joint in the stovepipe leading to the chimney,which is objectionable in tending to obstruct the draft and affording lodgment to soot, to better adapt the roof-plate to be adjusted for securing the required erect position of the stack, and to better adapt the roof-plate to shed rain from the opening in the roof through which the stack extends.

My objects thus referred to are accomplished by the construction illustrated in the accom panying drawings, in which- Figure l is a perspective view showing a chimney equipped with my improvements in the form provided to permit the application of the chimney in erect perpendicular position to the apex or ridge of a sloping roof, a broken portion of which is represented. Fig. 2 is a section taken at the line y 2 2 on Fig. l and viewed in the direction of the arrows. Fig. 3 is a section taken at the line 3 3 on Fig. 1 and viewed in the direction of the arrows. Fig. 3l1 is an enlarged broken perspective View showing details of construction of the hinged sectional form of the roof-plate and parts con-V nected therewith.

A denotes the upper part of the pipe of a stove, not shown, but supposed to be located in a building B of any of the varieties commonly provided along railroads for sheltering gatemen and other employees, the sloping roof of the building being represented at C. The pipe A` projects through an opening o in the roof-apex.

I) is the stack, shown to be surmounted by a draft-ventilator E, which may involve any suitable construction and which seats at its lower expanded end over the upper projecting end of the stovepipe,where it is provided with a circumferential flange shown in its preferred form of an inverted pan. An annular serial No. 118,282. on moda.)

Fig. 3, where they overlap, and being pivotally connected together to hinge them, as shown at o, the pivots e: also passing through theadjacent sidesof the shield c to hinge the stack and roof-plate together. members of a corresponding pair of the flanges e are thus hinged together, one should be off' set, as represented at t in Fig. 3, to produce a flush joint. The flanges e form a shield H to be overlapped by the shield c. Beyond the pivotal connection between each pair ofv the hinged anges e the adjacent ends of the two plates (l are formed with mutually overlapping circular beaks ff', closed at their outer ends, as shown at f2, and adapted to work hinge-like one within the other and form a shell G for a purpose hereinafter explained.

To set the sectional roof-plate F, the plates d are adjusted about the apical opening a in the roof to extend over the shingles about the opening and with the lower portions of the flanges e abutting against the shingle ends about the roof-opening, as shown. ing the stack D iii-position the depending shield c overlaps the shield F, and the stack carrying the pipe A is fastened in erect position by bolts g g, shown hooked at their lower ends to engage with eyes g onthe plates (Z and passing at their upper threaded ends through perforated lugs g2, projecting from sides of the shield c adjacent to recesses 7L in the edges of the flange b, where the bolts are adjustably fastened at opposite sides lof the perforated ears by nuts g3 g4.

By the construction thus described the roofplate may be pivotally adjusted to extend the stack vertically from the roof at any angle to Where theA In plac- IOO a pipe leading from a stove in the building and connecting with the pipe A at its lower end by loosening the nuts and turning the stack, as required, crosswise of its vertical axis withoutdestroying the overlapping relation of the shields c and H, which would ex pose the opening a to the ingress of rain, snow, and the like, and without destroying the overlapping relation of the bealfsff, with a similar effect, the immediate purpose of the beaks being to extend the shielding of the opening a at the roof-apex, over which the overlapping beaks join the ends of the plate-sections d d of the roof-plate.

rhat I claim as new, and desire to secure by Letters Patent, is-

l. In combination with a chimney of the character set forth, a sectional roof-plate conforming to a roof-apex to straddle the same, and an adjustable connection between the chimney and roof-plate maintaining closure of the roof-opening at any angle of adjustment of the chimney on said plate. A

2. In combination with a chimney of the character set forth, a roof-plate formed of hinged sections to straddle a roof-apex about the chimney-opening therein and having an upward projecting sectional shield, and a downward-projecting shield extending about the chimney, said chimney and roof-plate being fastened together and relatively adjustable with said shields overlapping one another, substantially as and for the purpose described.

3. In combination with a chimney of the ycharacter set forth, a roof-plate formed of character set forth, a roof-plate formed of hinged sections to straddle a roof-apex about the chimney-opening therein and having an upward-projecting sectional shield, mutually overlapping end-closed curved beaks joining the roof-plate sections across the roof-apex beyond the sides of said shield and a downward-projecting shield extending about the chimney, said chimney and roof-plate being fastened together and relatively adjustable with said shields overlapping one another, substantially as and for the purpose described.

5. In combination with a chimney of the character set forth, a roof-plate formed of hinged sections to straddle a roof-apex about the chimney-opening therein and having an upward-projecting sectional shield mutually overlapping end-closed curved beaks joining the roof-plate sections across the roof-apex beyond the sides of said shield, a flange extending about thel chimney and a shield depending from said flange, said chimney and roof-plate being fastened together and relatively adjustable with said shields overlapping one another, substantially as and for the purpose described.

6. In combination with a chimney of the character set forth, a roof-plate formed of two three-sided sections each having flanges crossing their inner edges with their ends overlapping one another across the roo f-apex and pivotally connected together, said flanges forming an upward-projecting shield, mutually overlapping end-closed curved beaks joining the roof-plate sections adjacent to the pivotal connections of said fianges, a fiange extending about the chimney, and a shield depending from said fiange, said chimney and roof-plate being adjustably pivoted and bolted together and said shields overlapping one another, substantially as and for the purpose described.
