y This invention relatesv more speciflcallyi vto Aadevicve lfor chemicalizing flowing Water, and isan improvement of my apparatusentitled ,Device for impregnatingl flowing vvaterfcr g ,which U. S. Letters Patent No. 1,582,225 issuedtomeon April27,1926. The apparatus ,described in the above mentionedvlpa'tent provided for a single chemicalcontainer'and a tvalve:orreleasing the chemicals therefrom loivhenit wasdesired t-ochemicalize the flowf, tion of, the', device is avoided.

.225 .lt'is therefore achiefobject of my invenltion to y provide a device that maybenreadily fconnected, to the jiuid discharge pipes vof `,phnilbing fixtures, Asuch as7 showers, bath tubs l:and the like;` and Which `may, be utilized lto f chemicalize the Water, iovving through, the fiixtures in .a number of lsuccessive pperations.`

Chemical containers 12I tre.. removably supportedxmthe cylindlsl bymeans ef a ro- Qlyxgre'ater fI-Vulils` 'thanthe radius of cylindersfin'orderthat the vmember Will'ofer no provided with a centrally disposed bearing" lug 16, while at the lower ends of the cylin- 1 ders is a similar bearing lug 17, the boresvof both lugs being in alinement. Mountedin the bores of lugs 16, 17 is a shaft 18 that extends beyond the upper surface of the cover member to which is rigidlysecured'in anypsuitable manner alhand wheel 19 preferably. formed of bakelite or other non-corrodible substances. f Mounted on the lower end of shaft 18, is

a double edged shearing knife 22, adapted when the arm is rotated throughthe medium Y' of the hand wheel 19 to successively form a slitted opening in each of the containers to expose the chemicals carried thereby to the action of the water flowing` through the device. i Y i From the above it is thoughtrthat the operation of the device will be obvious. loading the cylinders with filled containers the cover member is unscrewed and upended. The rotatable member 14C isthen turned until its segmental openings register with the open ends of the cylinders to permitthe insertion of the chemical containers in the cylinders, the member being again rotated over the open ends of the cylinders to supportthe containers in position. Cover member is then inserted in the casing and secured thereto. When a person desires to obtain `a perfumedbath or shower, the hand wheel is rotated to force the shearing knife 22 into engagementwith one of the sealed cylinders to form a lateral cut therein to expose the chemical therein to the action of the fluid flowing through the device. vTheV content-sof one container will usually be sufficient to perfume or chemicalize a bath or shower of usual duration. Additional baths or vshowers maybe obtained until all the containers .are emptied, when Y fresh ones may be inserted` As in my patent above referred to the chemicals employed are for the purpose of softening the water, or perfuming the same, and as the salts employed are readily soluble all danger of clogging the device is obviated.

As the chemical containers are formed of inexpensive materials as well as the chemicalsf employed, it will be apparent that the same may be vended at slight cost.

What I claim is: A

A deviceof the class described comprisinlet to aiiuid pressure supply line, a chemicalcontainer formed of a fibrous material detachably VVmounted in said casing, and rotatable cutter means to mutilate a wall of said container toV expose the chemicals disposed `therein to the action of the fluid passing through the "casing I Y. L1. A device of the class described comprising a casing having'fiuid inlet and outletY openings the inlet opening adapted to be connected to a source of fluid supply, a sealed paper cylinderV for holding a chemical detachably mountedin said casing, and a manually operated shearing knife Vmounted in said casing for forming an opening in a fluid inlet andY outlet openings adjacent the bottom of said casing, the inlet adapted to be Vconnected to a source of fluid pressure, a clo-v v sure for the upper endof said casing having Y a depending cylindrical casing having an open lower end for the reception of 'a chemi- Y cal container, means to support the container in said cylindrical casing, a container cuttin knife carried said casing closure `an means for rotating the knife to'cut the container yfor releasingthe chemicals contained therein to impregnate the fluid as it passes through the casing.

6. A device of theclass described comprisingv a casing having fluid inlet and outlet openings,l said inlet opening adapted for connection to a'source of iiuid supply, the upper endof said-.casinghaving a removable closure, a yplurality of chambers formed on the :underface of said closure forholding chemical containers, said containers being removable, means for supportmg'the containers in position iny said chambers, land rotatable means carried-by said closure for forming an opening in the containers successively to v release the chemical contained therein to the action of the flowing Huid passingthrough the casing, whereby to impregnate thefluid.

7. A deviceof the class described comprising a Casing open at its upper end and hav-A ing oppositely disposed fluid inlet and outlet openings adjacent its lower end, said inlet opening adapted to be connected to a source of fluid pressure, a removable closure for said casing having a plurality of compartments open at their lower ends for the reception of chemical containers, a rotatable shaft carried by said closure having means on its upper end to rotate the same, a shearing knife carried by the lower end of said shaft and extending transversely therefrom for successively forming a cut in theV Wall of each of said chemical containers to expose the chemicals carried thereby to the action of the fluid as it passes 'through the casing, and a flat circular member having openings in its edge carried by said shaft for supporting. the chemical containers intheir compartments, said member adapted to be rotated to move the openings therein into registerwith the open ends of the compartment to permit of the removal. of the empty containers and the insertion of filled ones. v
