CHEMICAL-RETAINER FOR SEWER-PIPES.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed October 12, 1920. Serial No. 416,365.

T 0 all whom it may concern:

Be it known that I, NnLsoN R. HAGEMAN, a citizen of the United States, residin at Reno, in the county of VVashoe and tate of Nevada, have invented new and useful Improvements in Chemical-Retainers for Sewer-Pipes, of which the following is a specification.

This invention relates to a chemical container for use on vent pipes of sewers and the like for purifying the gases from the sewer before they escape into the atmosphere, the principal object of the invention being to provide a container which can be easily and quickly refilled with the chemical and which is so formed as to make the gases pass through the chemicals before escaping from the device. 7

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view through the invention.

Fig. 2 is a cross section on line 22 of Fig. 1.

In these views 1 indicates a cylindrical container which is provided with a reduced lower part 2 which is screw threaded to engage the screw threaded upper end of the vent pipe 8. The bottom of part 1 is provided with a hole 4 which is of smaller diameter than the diameter of part 2 and the lower open end of a perforated tube 5 is threaded in said hole. The upper end of this tube 1s closed as shown. Short pipes 6 have their inner ends connected with the upper part of the container, the outer ends of these pipes extending downwardly as shown. The top of the container is closed by the screw threaded cover 7.

It will thus be seen that when the device 1s placed on the end of a vent pipe and a suitable purifying chemical placed therein the gases passing from the vent pipe will'be caused to pass into the perforated tube 5, through the perforations therein into the container and after passing through the chemical will flow from the pipes 6. Thus the gases will be purified by the chemicals so that they will be free from all injurious properties when they escape into the atmosphere.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A device of the class described comprislng a container having a reduced lower end screw threaded to engage the screw threaded upper end of the vent pipe, a perforated tube within the container having its lower end in communication with said reduced part and its upper end closed, a vent pipe connected with the upper part of the container and a screw threaded cover closing the top of the container.

In testimony whereof I affix m signature.

NELSON R. HA EMAN.
