I BOOZE FLASHING.

Application filed April 11,

The main object of this invention is to provide an improved roof flashing which is highly eflicient for the purpose and at the same time is economical in structure and, easily adjusted to meet roof conditions and to the flue associated therewith.

Objects pertaining to details and economies of my invention will appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawingforming apart of this application, in which:

Fig. 1 is a side elevation of my improved roof flashing shown in operative relation to a flue.

Fig; 2 is a vertical central section on a line corresponding to line 2-2 of Figs. 3 and 4. v

Fig. 3 is a detail vertical section on a line" corresponding to line 33 of Fig. 2.

Fi 4 is a fragmentary view looking from the right of Fig. 2.

Fig. 5 is an enlarged detail on line 5- of Fig. 4;

. Referring to the drawing, 1 represents a pipe or flue which I have shown in order to clearly illustrate the use of my improved flashing. My improved flashing comprises a base member designated generally by the numeral 2 and having opposed flat side walls 3 and cylindrically curved upwardly converging end walls 1. These walls are provided with flanges 5 at their lower ends. The top member designated generally by the numeral 6 has flat side walls 7 embracing the side walls I of the base member and pivoted thereto at 8, the lower edges 9 of the side walls being pref erably upwardly inclined thereby permitting the arrangement of the pivotwell toward the bottom of the base member and the swinging of the top member on the pivot.

The

end walls

10 and 1 1 of the top member are also'preferably substantially flatand are upwardly inclined. The upper portion of the ends and side walls of the top member is shaped into acylindrical form to receive a round pipe.

The top member is preferably formed of a single sheet of material with the edges 12 and 13 of the sheet overlapping, the edge 12 being folded upon itself to form a seam channel l l'into which the edge 13 projects. These overlapping seam parts are pivoted fat 15 1928. Serial No. 269,173.

adjacent the lower edge of the top member and are provided with opposed ears 16 adjacent their upper ends through whichfthe clamping bolt 17 is arranged so that the top member maybe clamped upon the pipe or flue as one.

1 preferably provide a gasket or packing 18 Y which is of U cross section and arranged over the upper edge of the top member so as to render the joint substantially watertight.

,may be easily applied and adjusted, or installed and adjusted, to the pitch of the roof and has a substantial range of adjustment to i the flue.

Having thus described my invention what I claim as new and desireto secure by Letters Patent is:

1. An adjustable roof flashing comprising a base member having flat parallel side walls and cylindrically curved end walls, a top member having opposed substantially parallel side walls and downwardlyinclined substantially flat end walls embracing, the corresponding walls of said base member, the upper portions of said slde and end walls being conformed to approximately circular n 'IOIIH, said side and end walls of sald top member being formed of a slngle SllGGt-Oflllit- To support the top memberin its adjusted terial havingoverlapping vertical edges disposed centrally of one of the end walls, said overlapping edges being conformed to provide a telescoping seam joint and being pivot ally connected adjacent their lower ends,

clamping ears disposed in opposed relation to the adjacent edges ofsaid top member ad:

jacent the top thereof, a clampingbolt coacting with said ears, whereby the top member may be clamped upon a flue, pivots connecting the side walls of said top member 7 to the sidewalls of said base member disa posed centrally thereof and acent to their lower edges, one of said side walls of said top member being slotted, and a bolt on one of the base member side Walls disposed Walls 01 said top member being formed of a iny'hzind.

single sheet of material having overlapping vertical edges disposed Centrally oi one of the end alls, said over zipping edges being conformed to provide a telescoping seam joint and being pivot-ally connected 11dincent their lower ends, clamping ears disposed in opposed relation on the adjacent edges of said top member adjacent the top thereof, and a clamping bolt enacting with said ears whereby the top member may be clampedupon a flue,
