Claims.

This invention pertains to detergents; and more particularly to a detergent in cartridge form adapted to be inserted into waste pipes for eliminating and preventing the collection of greasy 5 matter and other waste particles which would tend to clog up the pipe.

Heretofore, clogged waste pipes have been cleaned by means of a suction device, or by pouring a soda and lime mixture into the pipe to dis10 solve the accumulated waste matter. This cleaning procedure is performed, as a rule, only when the pipe has become clogged to such an extent as to be a source of annoyance. When the pipe has reached such a state obviously the cleaning 15 operation is more difficult than if the pipe were cleaned while waste matter is passed therethrough.

It is an object of this invention to provide a plug of detergent material which can be inserted 20 in a waste pipe to prevent accumulation of greases and other waste matters.

A further object is the provision of a detergent plug for insertion in waste pipes, which plug is formed in such a manner as to offer substan 25 tially no impedance to the flow of water through the pipe.

A further object of the invention Is to provide a plug of detergent material so constructed that it may be readily Inserted within and supported 30 by the ordinary waste pipe strainer.

A further object of the Invention is to make such a plug of soluble material, provided with longitudinal apertures so that waste matter, before passing into the. waste pipe, must Alter 35 through the plug apertures, whereby the soluble detergent will be carried with the waste matter into the waste pipe, automatically and constantly cleaning the waste pipe during the passage of waste matter therethrough.

These and other advantageous objects, which will later appear are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and ⁴⁵ in which:

Fig. 1 is an exploded view showing the manner in which the detergent plug embodying the invention is inserted into the strainer head, ₅₀ Fig. 2 is a vertical sectional view of the plug inserted, the plug being shown in elevation,

Fig. 3 is a top plan view, partly in section, of the structure shown in Fig. 2,

Fig. 4 is a top plan view of the plug, 55 Fig. 5 is a bottom plan view thereof, and (CL 87—5)

Fig. 6 is a side elevational view, partly in section, of another form of the invention.

Referring to the drawing, in Fig. 1 there is shown a waste pipe f having connected thereto a strainer head 2 in the usual manner to form a 5 chamber which is covered by a perforated disc 3, as is common and well known in the plumbing art. The strainer head 2 has its lower portion provided with strips 4 which provide four quadrant shaped apertures forming a strainer through IC which waste matter passes.

In Fig. 2 there is shown a plug 5 of detergent material such as soda and lime, or other chemical compounds which are capable of dissolving greasy matters. The plug 5 is substantially cy- 15 lindrical in shape and has a head 6 having a plurality of passages 7 through which the waste matter passes. The main body of the plug 5 is divided longitudinally into four parts 8, each of which is substantially quadrant-shaped in cross ₂₀section and adapted to pass through the apertures between the strips 4 in the strainer connected with the waste pipe I. The parts 8 have passages 9 extending therethrough to further facilitate the passage of liquid waste material. In other words, the plug is provided with as many apertures, or grooves, as possible so that the plug itself will not impede the passage of waste matter through the pipe I.

From the above description it will be seen that a simple detergent device has been disclosed ⁰⁰which can be readily inserted into a waste pipe to continually provide means for preventing the accumulation of greasy matter or other waste products which tend to clog the waste pipe.

While herein is shown the plug as being di- ³⁵vided into four forked sections 8, which fit over the strips 4, it should be obvious that such a division of the plug is not necessary where a waste pipe is not provided with a head having ._nthe strips 4 as illustrated herein. In waste pipes ⁴⁰not provided with strainer strips 4 the detergent plug would rest upon the head 2 and it would not be necessary to subdivide the plug into four· parts 8.

The underside of the head 6 of the plug is pro- ⁴⁵vided with suitable means 10 to space the plug from the member 4 in order that those passages 9 which would register with the said member 4 will not be blocked thereby.

The plug may be provided with arcuate pas- ° sages 9 as shown in Fig. 1, or with passages 7a extending longitudinally throughout the length thereof, as shown in Fig. 6, or any other suitable arrangement of passages may be provided.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed in5 eluding many modifications, without departing from the general scope herein indicated and denoted in the appended claims.
