ROOF SUMP.

Application filed January 31,1924. Serial No. 689,701,.

To all whom it may concern:

Be it known that I, EDWARD W. N. BoosEY, a citizen of the United States, residing at Detroit, county of Wayne, State of Michi gan, have invented a certain new and usefui Improvement in Roof Sum'ps, and declare the following to be a'full, clear, and exact description of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference bein had to the accompanying drawings, hich form a part of this specification.

This invention relates to roof sumps and the object of theinvention is to provide a roof sump which is leak proof andjwhich.

may be easily secured in position in any type of roof. Another object of the invention is to provide a roof sump which may be readily cleaned and which will not easily become clogged. A further object of the invention is to provide a roof sump which when placed in position requires no further attention and which is composed offew parts and is of consequent low manufacturing cost. Another object of the invention is to provide a roof sump which is adjustable fcr use in roofs of varying thickness.- A further object of the invention is to provide a roof sump positioned in an opening'in the roof in which the roofing extends into the opening and is bindingly secured within the basin of the sump to prevent leakage. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of constructionby which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a" section through a roof sump embodying my invention.

The drain conduit 1 terminates short of the roof which comprises the roofing boards 2 having a roof 3 thereon which may be anyparticular type, but is usually prepared roofing, gravel surfaced roofing or the like which is impervious to water and is flexible. The roofing -boards.2 are provided with an aperture 4 cut therethrough over the upfpler end of thedrain conduit 1 and the roo g 3 extends over the roof boards 2 and into the aperture 4 as shown. A basin 6 is provided having a flange 7 which is supported on the roof boards 2 beneath the roofing 3 and the basin 6 at the lower edge extends in spaced relation with the drain conduit 1 and is prevent leakage between the drain conduit and the member 6. The upright member 11 of the sump is provided with a series of apertures 12 through which water ma flow into the drain conduit 1 and this mem er 11 at the lower edge is provided with a flange 13 resting on the lugs 5 provided on the annular shoulder 14; in the basin 6. A series of threaded rods 15 are secured in vertical pos1t1on in bosses 16 provided therefor in the member 6 and these rods 15 extend upward- 1y through an annular member 17 which is substantially V shaped in cross section as shown. This annular member 17 is provided with a conical face cbrresponding with the conical face of the basin and engages against the portion of the roofing 31 extending into the aperture 4 and by threa ing the nuts.18 on the shafts 15 downwar ly, the Linwardly extending portion of the roofing 3 is bindingly engaged between the conical face of the annular member 17 and the conical face on the inside of the basin 6. An-annular member 19 substantially conical in form is provided with an aperture in the end thereof which fits over the upright mem- 'ber 11 of the sump and the member 19is provided with ave'rtical' flange 20 at the lower edge which engages the surface of the roofing 3. This member 19 is rovided with a series of apertures 21 throng which water may flow to the interior of the sump and these apertures terminate above the lower edgeof the'member'19to prevent the gravel on the roofing from passing into the interior of the sump. The member 19 is provided with a series of depressions 22 which are apertured and through which the threaded rods 15 extend, nuts 23 being provided'on therods 15 which may be turned down to bindingly secure the roofing 3 between the flange 20 of the member 19 and flange 7 of the member 6 and prevents water from enterin between boar s 2.

the roofing 3 and roofing This device is adjustable for use with roofs of varying thickness and when a concrete surfacing is used on the roof it is usually of a greater thickness than the type of roofing shown at 3 in Fig. 1. When the device is to be used with a concrete roof as shown by dotted lines 24 in Fig. l the concrete roof ing rests directly on a lead flashing 3 which replaces the roofing 3. In this case when the member 19 is positioned over the upright member 11 of the sump the annular flange 20 engagesthe surface of the concrete roofing and the nuts 23 shown on dotted lines in Fig. 1 are turned down to bindingly secure the flashing 3 and concrete roof 24 between the flange 7 of the basin 6 and the flange 20 of the member 19. In use the water passes through the apertures 21 in the member 19 and through the basin 6 and over the member 17 and through the apertures 12 in the member 11 into the drain conduit 1. B providing the lugs 5 the flange 13 of the upright member 11 is spaced from the shoulder 14: and allows water to pass therebetween so that no water will remain in the sump. B this construction a roof sump is provided which is adapted for different types of roofs and which is adjustable for use with roofs of varying thickness.

From the foregoing description it becomes evident that the device is very simple and efiicient in operation, will not easily get out of order, is composed of few parts and is of consequent low manufacturing cost and provides a device which accomplishes the objects described. Y

Having thus fully described my invention, its utility and mode of operatic what I claim and desire to secure by Lett s Patent of the United States is- 1. A roof sump comprising a basin adapted for connection with a drain conduit, the basin being provided with a conical inner face, a series of threaded rods supportedvertically in the basin, an annular member apertured to receive the rods and movable longitudinally thereof, the annular member having a conical face extending parallel with the conical face of the basin, a flashing or roofing extending between the conical faces of the annular member and basin, a series of nuts carried by the threaded rods adapted to be turned down to bindingly secure the flashing or roofing between the conical faces of the annular member and basin, an upright apertured member extending over the drain conduit, a conical member having a central aperture through which the upright member extends and provided with a series of smaller apertures through which the upper ends of the rods extend, a series of nuts carried by the said rods adapted to be turned down to bindingly engage the edge of the conical member against the roofing, the conical member being provided with a series of apertures open to the basin.

2. A roof sump comprising a basin adapted for connection with a drain conduit, the basin being provided with a conical inner face, a series of rods supported vertically in the basin, an annular member apertured to receive the rods and having a conical face extending parallel with the conical face of the basin, a flashing or roofing extending into-the basin between the conical faces of the basin and annular member, means whereby the annular member may be forced downwardly to bindingly engage the flashing or roofing between the conical faces of the annular member and basin, an upright apertured member extending over the drain conduit and an apertured conical member secured in position about the upright member.

3. A roof sump comprising a basin having a central discharge aperture and adapted for connection with a drain conduit, a flashing or roofing extending into the basin,

right apertured member supported by the basin and extending over the drain conduit, a conical member fitting about the upright member and having a series of apertures open to the basin and means for adjusting the conical member in relation to-the edge of the basin.

4:. A roof sump comprising a basin adapted for connection with a drain'conduit, a 'flashing or roofing extending into the basin, means for bindingly securing the flashing or roofing to the inside of the basin, an upright'apertured member supported by the basin and extending over the drain pipe, a conical member fitting about the upright member and adjustablemeans for drawing the edge of the conical member into tight engagement with the roofing.

5. A roof sump comprising a basin adapted for connection with a drain conduit, an apertured member supported in the basin in vertical position over the drain conduit, a conical member fitting about the apertured member and provided with apertures open to the basin, and means for adjusting the conical member in relation to the edge of the-basin.

6. A roof sump comprising a basin having a conical face adapted for connection with a drain, a flashing or roofing extending into the basin over the said conical face, a ring member having a corresponding conical face to bind the flashing to the basin, a separate grating member extending over the basin and lying in engagement with the flashing above the basin, threaded standards extending upward from the basin and;
