June 23, 1931. s. A. HARTMANN DRAINAGE SYSTEM Filed Jan. '7. 1930 A Homey Patented June 23, 1931 UNITED STAT SAMUEL A. HARTMANN, OF JACKSON, MISSOURI DRAINAGE SYSTEM Application led January 7, 1930. Serial No. 419,090.

This invention appertains to new and useful improvements for drainage systems for buildings, and the same has as its principal object, provision whereby circulating waters may be trapped beneath a building and drained off to a sewer or some other remote point.

Another important obj ect of the invention is to provide a drainage system which after '10 being installed will not require further atbuilding showing the ditches layed off andV filled with suitable coarse granular material through which water may easily seep.

sectional View substantially on line 2 2 of Figure 1.

Referring to the drawings, wherein like numerals designate like parts, it can be seen in Figure 2, that the numeral 5 represents the footing or foundation for the walll 6, this being all of the building disclosed in the drawings. f

In carrying out the present system, a vertical bore 8 is made to terminate at a level beneath the footing 5 and at spaced intervals outside of the confining area of the footing 5. Whether a ditch is dug straight downwardly or the work is consummated by tunnelling, is immaterial in providing the inwardly disposed ducts 9 which communicate the lower ends of the bores 8 with the ditch 10.

This ditch 10 extends in close proximity to the inner side of a building wall 6 and beneath the bottom level of the footing 5, as in the manner shown in Figure 2. A diagonally disposed ditch 11 connects one corner of the ditch 10 with the diametrically opposite corner and in this last mentioned corner a drain Figure 2 represents a fragmentary vertical opening 12 is provided for communicating the ditch 10 with a drain pipe 13.

The ditches 10 and 11, and the ducts 9V are filled with some suitable coarse granular material such as crushed rock or gravel and asV shown in Figure 2, the bores 8 are filled to the level 14 with this material, and from there upwardly with earth.

The concrete or cement floor or covering 15 is then laid over the entire area withinthe confines of the footing 5. It will now be seen that any water percolating through the ground beyond the side walls of the building will eyentually form fissures leading to the ducts 9 and when water has gained this point, the same will readily sift through the granular material and ultimately pass into the drain pipe 13.

Thus the walls and iioo'ring 15 will be maintained constantly dry by the novel system of drainage.

Obviously certain variances of the system may be resorted to to accommodate various shaped structures without departing from 'the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

The combination with a building including foundation walls and a bottom floor, of drainage means for the building comprising ditches arranged below the walls and floor and within the Vconfinesof the wall and following the outline thereof, a diagonal ditch connecting the corners of the first ditch together at opposite points, a drain'pipe connected with the first ditch, and lateral ditches connected with the first ditch and extending' below and beyond the foundation walls.

In testimony whereof I affix my signature.

SAMUEL A. HARTMANN.
