DRAINAGE VALVE.

Application filed March 18, 1925.

To @ZZ whom t may concern:

Be it known that I, HERMAN MocKUs, a citizen ot the United States, residing at Chicago, in the county et Cook and State ot illinois, have invented new and useful lmprovements in Drainage Valves, ot which the following is a. speciiication.

This invention relates to new and useful improvement-s in drainage valves and more particularly to a. device of this character which is applicable to drainage openings and the like which are usually placed in the floors of basements, cellars, etc.

rlhe main object of my invention is the provision ot a drainage valve whereby the same is so constructed as to be readily applied to the usual drainage openings in basements and is normally in a closed position to prevent any backing of water from the sewer from entering the basement and which can be quickly and readily actuated when it is desired to drain any water from the basement floor.

Another object of my invention is the provision of a drainage valve including suitable means for normally retaining the valve in a closed position with additional means whereby the same may be manually manipulated for operating the valve to permit drainage thru the drain pipe to which the valve is attached.

A further object ot my invention is the provision of a drainage valve wherein the operating parts thereof are within the usual concrete iooring in basements and the like so as to prevent articles from being brought into contact with the working parts whereby the valve will be ready for operation at all times.

With the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which:

Fig. 1 is a top plan View of the drainage valve constructed in accordance with my invention, parts thereof being broken away and illustrated in section,

Fig. 2 is a longitudinal sectional view, and

Fig. 3 is a detail transverse section on the line 3 3 of Fig. l.

Referring more particularly to the drawings, the numeral 1 indicates a drainage pipe leading to weil-known drainage system Serial No. 16,496.

and attached to the upper end ot this pipe is a catch basin 2, having a. perforated plate 3 arranged horizontally against the hasement adjacent the upper end thereot. This basin is usually set inte the concrete flooringet' a` basement and generally at a low spot whereoy any water on the iioor ot' the basenient will readily run toward the base 2. ris this catch basin 2 normally remains in an open position, the water from the sewer has a. tendency to back thru the same into the basement ot. the building and in order to prevent this backing of the water, I have constructed a novel 'term ot valve which normally closes the communication to the sewer and prevents any backing of water therein.

Suitable housings 5 and 6 are arranged adjacent the basin 2, said housings being preferably in spaced relation as shown in 2 and connecting the housings is a .sl-.neve .7,

lsl'ovable thru the housings 5 and G and the sleeve 7 is an operating shaft 8.' the inner end ot which is connected as at 9 to a perforated valve plate 10. The plate l0 is mounted within the suitable opposed guides 11 connected to opposite sides ot the basin 2.

The shaft S is provided adjacent its inner end with a head 12 which normally hears againsta shoulder 13 in the housing 5. Disposed between the head 12 and the outer wall of the basin 2 is a. coil spring 14: which normally retains the shaft 8 in an outward position with the hea-d 12, bearing against a shoulder 13. This position retains the periorations in the valve plate out ol' alignment with the pertorations in the plate 3. h

The housing 6 has extended outwardly therefrom a shaft 15, having a hand wheel 16 upon its outer end and a c ank arm 17 at its inner end which is arranged within the housing. The c'ank arm 17 is connected to the outer end of the shaft 8 by means of a link 18 whereby it will be noted that when the shaft is rotated, turning the handle wheel 16 to the right, the shaft S will he reciprocated inwardly toward the catch basin 2 compressing the spring 14 and moving the valve plate 10 so that the pertorations therein will be brought into alignment with the perforations in the plate 3, permitting any water standing above the .catch basin to be drained therethru,

In order to provide for proper alignment for the perforations in the plates 3. and 10, a stop pin 19 is carried by the shaft 8 and is adapted to engage with the shoulder 13 in order to limit the movement of the shaft 8 upon itsinward stroke, thus as the pin 19 strikes the shoulder, the plate 10 will have been moved a suiiicient distance to bring the perforations therein into alignment with the perforations in the plate 3.

It will be apparent from the'foregoing that when the hand wheel is released after completely draining` the water thru the basin, the tension of the spring 111- will return the shaft 8 to its normal position, closing the openings between the plates 3 and 10 whereby the drainage valve will always remain in a normally closed position to prevent any baclr-ingof the water from the sewer thru the drain into the building.

As noted the several parts o-f the device are embedded or arranged beneath the surface of the cement licor whereby they will be entirely out of the way and the hand wheel 16 may be located at one side of the basement and the shaft 8 connected thereto in any suitable mannen While I have shown and described the preferred embodiment of my invention, it will be understood that various changes and alterations may-be made without departing from' the spirit of the invention or the scope of the appended claims.

Having thus descr-ibed'my invention, what claim is: l

l. In combination with a catch basin having a stationary perforated plate therein, a movable perforated plate upon one side of' the stationary plate, a housing adjacent the 2. The combination with a drain opening having a perforated plate against the same, of a movable valve plate disposed beneath the first plate and having openings-therethru, a longitudinally movable shaft having one end connected to the valve plate, manu-- ally operated means connected toY the other end of the shaft, a head portion on the shaft,

a spring normally bearing against: the head for moving the shaft in one direction, a stop,

shoulder adapted to be engaged by the head to h mit the movement of the shaft, a pin carried by the shaft in spaced relation Vwith the head for engagingtjhe stop shoulder upon,

the opposite side to limit the movement of f the shaft in the opposite direction whereby the openings .in the valve plate mayVr be aligned with the perforations'in'the drain plate against the tension of the spring thruthe manually operated means and the tension of said springreciprocatingthe shaft in the opposite direction to move the openings in the valve plate out of alignment with the openings inthe drainv'plat'e. Y.

In testimony whereof I afiiX my signature.
