CLOSET RIM FLUSH Filed Aug. 20, 1935 Q (NVENTOR W W ATTORN EY Patented Aug. 4, 1936 CLOSET RM FLUSH James R. Beam, New Castle, Pa., assignor to Universal Sanitary Manufacturing 00., New Castle,

1 Claim.
The object of the invention is to provide a rim flush for water closets in which the jets are given an increased velocity over the normal rim jet of this character; to provide a rim flush in which the axes of the jets are at a pronounced acute angle to the plane of the rim, so that they may create a swirling eifect in the rim water much more intense than is possible under the conventional practice; and to provide a rim flush construction which is of simple form and susceptible of cheap manufacture.
With this object in view, the invention consists in a construction and combination of parts, of which a preferred embodiment is illustrated in the accompanying drawing, wherein:
Figure 1 is a view partly in elevation and partly in section of a closet equipped with the invention.
Figure 2 is a vertical sectional view, enlarged, through the bottom wall of the rim in the cylindrical surface in which the axes of the jets lie.
Figure 3 is a sectional view illustrative of the inclined rim jet employed conventionally.
The improvement constituting the invention consists in so modifying the rim II], which is of conventional form, that the jets issuing from its under face will be directed, with maximum velocity, against the surface of the bowl II but at an acute angle to the plane of the under face of the rim, so that a comparatively intense swirling motion is given to the rim water in its washdown function.
To this end, the rim is cast with lugs 12 on its under face, these lugs being substantially semicircular in cross section and each having its peak 14 of the arch lying at an obtuse angle to the under face l5 of the rim, the adjacent side or face [6 of the lug being at right angles to a plane tangent to the peak Hi. The jet duct is formed through the bottom wall of the rim and through the lug, and the rim on the interior of the bottom wall is raised as indicated at I8 at one side of a depression is, the raised portion acting as a sort of baffle to retard water flowing around the rim, so that it will be directed through the jet ducts l1 from which it will issue with considerable velocity due to the fact that the ducts lie at acute angles to the plane of the rim.
The increased velocity is due to the increase in length of the ducts I 7 over what is possible in the conventional practice, Where the lower wall of the rim (Figure 3) is punched to provide the ducts 2|, the ducts being at an angle to the plane of the rim. The effective length by which velocity to the rim water is given in such a duct is less, as shown by the lines 22 and 23, than the length possible where the lugs are employed; and the discharge mouth of the jet is open on the under side, which will cause the jet water to drop away laterally at the discharge mouth of the jet duct 5 and preclude the jet water following in a general line the axis of the jet duct. In the improved form, the jet issues from the duct at right angles to the face iii of the lug and there is no tendency for the jet water to drop off laterally from one side, as in the conventional practice illustrated 20 in Figure 3.
The angle of inclination of the jet ducts is such as to give the jet water the normal direction of swirl which, in this latitude, is left-handedly.
The invention having been described, what is 25 claimed as new and useful is:
A closet having a rim flush formed with jet ducts through its bottom wall and spaced lugs cast on the underface thereof with one in the area of each duct, the ducts each having its axis at an acute angle to the plane of said wall and continued through a lug and opening on a fiat face of the latter arranged in a plane at right angles to the axis of the duct, the upper faceof the bottom wall of the rim being depressed at one side of the intake end of each duct and having a raised portion directly above the eduction end of each duct and next adjacent the depression, the top face of the bottom wall of the rim being uninterrupted between the raised portion directly above one duct and the intake end of the next succeeding duct.
