To all whom it may" conccmi:
Be it known that I, XVILLIAMG. KIEFER, a citizen of the United States'residing at Brookline, in the county of Norfolk i and State of Massachusetts, have invented certain Improvements in Boot Pans, of which the following is a full, clear and exact description.
This invention relates to' building con-' struction and s herein shown as embodied in. a rooi' pan or down spout :t'or draining water from a' -flat root orthe like.
Although a -root pan for draining a roof is 'needed-inost :at. the time of very. heavy rains or of cloudburst, it has occurred, in
- prior constructions, that the suddenly accumulating water has-so choked the entrance to the spout that the air normally lying in the spout cannot escape. This may be due to the "fact that said prior constructions have straight side walls and the onrushing water tends to meet at the centerof the spout and seals the air against escape. Furthermore, the area of the opening is reduced by the metal in the fiat strainer usually employed. It is one of the objects of this invention to provide an improved construction of roof pan which will eiliciently drain water without choking the spout. In accordance with this feature, the spout is made of frustoconical shape with the result that the water tends to cling to the conical sides thus leaving, temporarily at least, a central passage for the air to escape. This also provides a larger entrance area and by utilizing a strainer o't dome like form the total area of the spaces between the metal neednot be reduced below that of the entrance.
In prior constructions shrinkage of timvber columns or expansion of the spout or of the iron drain pipe to which it is" connected, has resulted in the impairment of the j o1nt between the spout and the drain or between the spout and the roof line. Condensation of moisture on the pipe and subsequent dripping onto plaster ceilings have also been a source of complaint. It is accordingly another object of this invention to provide an improved spout which will avoid these and other undesired results. Inthe construction illustrated, the spout comprises an outer wall with an expansion joint and an inner wall spaced fronithe outer wall for its whole length to form an air chamber. These and other features, objects and advantages iii-tron will appear from a con'-' oi lili sideration of the following specification and accompanying-drawings in which I Fig. i is an elevation and half' section, andv I '1 L. i
V Fig. 2 is 'an' enlarged ot the. device.
trusto-conical shape. the upper edge or rim being bent outwardly as at 18, downwardly at 20 and back inwardly again at 22 to form a. second housing. This bent portion or bead is received in and is housed by the annular housing on the roof plate 4 and I makes a'tight joint therewith.
At the lower end of the inner wall 16 is a cylinderical extension 32 the end of which is received loosely in the upper end of a drain pipe 34. The inner wall 16 and the pipe 34 being out of contact, either can expand or contract without disturbingthe section ofa portion the other. Roof pans with a single wall cause condensation of moisture on the outside and this is objectionable. To avoid this, an outer wall 26 surrounds the inner wall for its whole length and provides an air: space betweein which diminishes passage of heat and prevents condensation of moisture. This wall has its upper rim bent outwardly asat 28 and then downwardly and inwardly at 30, the rim being housed bothin the rim of the inner wall 16 and in the rim of the roof plate 4 so that a tight joint is formed. The outer wall 26 is of inverted trusto-conical shape and in two sections the lower section 36 being joined: to the upper section 26 by an annular ring 88 U-shaped in cross section. The lower end of the outer wall is cylindrical as indicated at 40 and is surrounded and reinforced by a collar 42 joined to the upper end of the drain pipe 34 with a packing of oakum or the like between. Any I expansion of the drain pipe or the outer wall will not disturbtheir union Oll account of the expansible quality imparted by a e joi'ni as. A dome shapedstrainer 46 having openings lOQ is set in the mouth of the spout and anchored by the hooked anchor member 48. The metal of the spout is preferably copper and connects With a drain pipe of cast iron, wrought iron-or sheet metal.
Although the invention has been de scribed by reference to a specific einbodi ment, it should be understood that it is not necessarily limited thereto.
' I claim:
1. A device of the class described having, in combination, a plate extending substantially in the plane of a roof and having an opening, an inner wall attached to the plate at the rim of the opening, an outer wall attached to the plate and to the inner wall at the rim of the opening, said plate having an integral housing enclosing the ends of the inner and outer walls, and a drain pipe joined to the outer wall.
2. A device of the class described having, in combination, a plate having an opening with the rim bent into a substantially closed annular housing, an inner wall in the form of an inverted cone the base of which and an outer wall spaced from the inner wall and having its upper rim bent into said housing and into the bent rim of the inner wall I S. A device of the class described having, in combination, a roof having an opening, an inner closed Wall having a flange fitted to the rim of the opening and form ing a housing, and an outer closed wall spaced from the inner wall and having a flange enclosed within the housing of the inner wall.
4. A device of th class described having, in combination, a roof having an opening, an outer wall having its upper end" bent outwardly over the rim of the opening, a drain pipe receiving the lower endof the outer wall, an inner wall spaced from the outer wall and having, its free depending end of smaller diameter and extending into the drain pipe, said inner wall having its upper end bent outwardly over the upper end of said outer wall; substantially as described. i i a In testimony whereof I have signed my name to this specification.
