Application December 27, 1948, Serial No. 67,460

In connection with drain pipes connecting with a basement floor and a catch basin, it frequently occurs that the basement floor becomes flooded due to the rise of Water in the catch basin. Accordingly, the principal object of the present invention is the provision of a suitable valve co-acting with the end of a drain pipe which remains in the catch basin for automatically shutting off that end and thereby preventing the backing up of water from the catch basin into the basement.

Another object of the present invention is the provision of a suitable mechanism operable by a oat for actuating the valve into an operative or inoperative position with relation to the drain pipe for closing or opening the latter.

A still further object of the present invention is the provision of a valve cooperating with the end of the drain pipe, disposed within a catch` basin, operable by a iioat for shutting off the drain pipe as the water in the catch basin rises for preventing the water to pass into the basement through the drain pipe.

A still further object of the present invention is the provision of suitable tensioning means in connection with a Valve of the character indicated, which facilitate the valve to come into operative or inoperative positions, when actuated by a oat, for shutting off or opening the drain pipe.

Another object of the present invention is to generally improve a valve of the character hereinabove indicated.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views;

Fig. l is a vertical cross-section through a catch basin with the end of a drain pipe in an Claims. (Cl. 137-104) the latter.

operative position therewith, 4with the valve in at its upper end'with conventional closure I I. Let into said catch basin IB is one end of drain pipe I2, which partially extends into said catch basin ID. The other end of said drain pipe I2 leads 'to the basement of a dwellingV and usually is directed vertically for providing drainage from the basement into the catch basin.

To adapt said drain pipe I2 for operation with the valve constituting the subject matter of the present invention, the end of said drain pipe remaining within catch basin ID is shut by closure I3, provided with handle Ill, by means of lwhich said closure I3 may be either inserted into or withdrawn from the end of said drain pipe I2. Further, U-shaped pipe I5 is connected by one of its ends with said drain pipe I2, preferably at a lowermost point of the periphery of Said U-shaped pipe I5 constitutes a sealwhen filled with water, for preventing passage of gases from the catch basin into the basement. y

The other end of said U-shaped pipe I5 is provided With outwardly flaring mouth I5, and therebelow is provided with encompassing ring Il which is rigidly axed to said U-shaped pipe I5. Either rigidly-a`1xed to said ring I1 or integrally formed therewith are four arms i8 radially projecting from said ring Il. One of said arms I8, which extends into a lateral direction with relation to said U-shaped pipe I5 is longer than the remaining three of said arms I8, as seen in Fig. 3, for the purpose hereinafter specified.

Each of said arms I8 is formed in the shape of an angle bar, to include horizontal portions I9.

Extended through horizontal' portion I9 of each arm I8 is rod 2E, each of which is rigidly maintained by a pair of nuts 2l threadedly engaging each rod 2li and holding horizontal vportion I9 of each arm IS in a clamped interposed relation. Said rods 2Q are directed upwardly.

Afxed to the outer end of the longest of said arms I8 is supporting standard 22 extended therefrom to a vertical direction. Pivoted upon pin 23, passing through said supporting standard 22, is bar 2t, which is'capable to make angular swinging motions uponl said pin 23. Suspended 'upon one end of said bar 24 is float 25.

Said bar 2li is also made in the shape of an angle bar and through the horizontal portion of which, at the opposite end, rod 26 is extended. Rigidly affixed to the lower end of said rod 26 is valve head 2l which is disposed over mouth it of said U -shaped pipe I5, in a vertical relation.

Disposed above said valve head 2i is spider plate 28, through the center of which said rod 26 is passed and to which said spider plate 23 is clamped by means of nut 29. Said spider plate 28 effects four prongs S, each of which is in a vertical alinement with each arm I8. Through each of said prongs 30 one of said rods 20 is passed.

Threadedly engaging the upper end of each rod 2G is nut 3i. interposed between nut 3i and a given prong Sil, and in an encompassing rela tion with each rod 2i? is Vcoil spring 32.

Coil spring 33 is interposed between nut 29 and the horizontal portion of bar 24 and is in an encompassing relation with said rod 26.

Set upon the upper end of rod 2 is coil spring 34, which is interposed between the horizontal portion of bar 24 and nut 35, the latter being in a threaded engagement with the upper terminaw tion of said rod 25.

In the inoperative, open position of valve head 21 with relation to mouth i6 of U-shaped piper i5, bar 24 remains in a horizontal position. In that inoperative position of valve head 2l, springs 32, bearing against prongs and spring 3Q, bearing against the horizontal portion of bar 2Q, prevent the adjacent end of said bar 2li to make any further upward shifting movement, and counteract the weight o float 25. When however water in catch basin lil rises it elevates iioat 25, causing the adjacent end o bar 2t to shirt upwardly, thereby causing the opposite end of said bar 24 to shift-downwardly. The downward shifting of said latter end oi bar 2d exerts pressure upon coil spring 33 and causes the latter to press upon nut 29 .tor shifting plate 2S and valve head 2l downwardly. This action brings valve head 2l into mouth it, effectively closing the latter and. preventing the collecting water in catch basin it from passing into U-shaped pipe l5 and drain pipe i2.

The unusual amount of water in catch basin il), which may rise above float 25 and bar 2li and submerge the two, will not detract from the operativeness of the valve. Water submerging float 25 will increase its buoyancy and therebi7 the pressure of bar 2.13 at its end adjacent rod 2t, thereby further compressing spring 33, and when the latter is compressed t0 the fullest extent, the end of said bar 2d above spring 33 will be When valve head 21 remains in an operative position within U-shaped pipe l5, springs E2 and 35i remain entirely in a loose condition upon their respective rods 2B and 26.

When water in the catch basin falls iioat 25 will necessarily fall with it for shifting bar 24 back into its normal, inoperative, horizontal position. The shifting of said bar 2li into that latter position is assisted by spring 33 as it bears pressure upon the underface of the horizontal portion of said bar 25: for driving the adjacent end of said bar 2d upwardly. This action of course elevates plate 28 with its prongs 3i) and brings valve head 2 out of mouth it of Lbshaped pipe i5. In the inoperative position of valve head 2l springs bearing against prongs 33, spring Sii, bearing against the horizontal portion of bar 2d, provide means for maintaining said bar 2t in a horizontal position by counteracting the weight of float 25, which at this stage is not supported by water but hangs upon the adjacent end of said bar Zei. In any sudden fall of Water in catch basin it said springs 32 and siact as cushions for preventing jarring of the mechanism as the adjacent end of bar 2d makes sudden upward thrust.

Rods .26, being passed through prongs 3d, constitute guiding means for said spider plate 2S and valve head 2, by virtue of which arrangement valve head 2 is guided in its shifting in a incapable oli further downward shifting. ,7.

true vertical direction so that it may be shifted into mouth i6 or out of it without difficulty and without'disarrangement of parts. The opening in the horizontal portion of bar 2li, through which rod 2t is passed, should be made oblong relative to the length of said bar 2t, so as to permit accommodation of said bar 2:3 with relation to said rod 2B as the former 'makes angular shifting motions with relation to said rod 2t.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
