SLIP-SLEEVE VALVE.

r nsa'tsn filed May 1s, 1923. Serial No. 639,987.

Ta'aZZ whom a may mm. 1

Be itlznownthat I, EDNVARD M. HA Bn-n soN, 'a" citizen of the United States, residing at 'Los Angeles, in the county of Los An geles and State of California, have invented new; "and useful Improvements in Slip-Sleeve Valves, of which the following'is a specification. V I

My present'invention being a slip sleeve valve, it is an object oftliis invention to replace theusual'cap at the end of a drain pipe, or the like, by a construction which ,may present substantially the appearance of a cap'upon a'nipple, and may nevertheless comprise means for directing the outflow of a dr'ainedliquid in a desired direction.

It is a'furtheri object of this invention to provideineans of the character referred to which may cooperate in guiding a cap durmg the seatlng of the same and which may also comprise a gasket or gaskets arranged effectively to prevent leakage when said cap is "seated; and my 'preferred construction for the'purpose referred to may comprise a cap swivelled to a laterally apertured sleeve insuch a manner as to. retain a plu rality of relatively movable gaskets in place, means being optionally provided to hinder or prevent'the complete separation of the parts referred to, 'withconsequent risk of loss or misplacement. I

Other object of my inv 'ntion will appear from the following"description of a p refer'red embodiment/thereof and fromthe appended claim's,'ta'ken connection with the accompanying drawings, in which Figure 1' is a vertical s e ction through one form of valve embodyingmy invention and showing the valve as closed.

Fig. 2 is a corresponding view, the valve being shown as open, and a modified form of sleeve-retaining means being shown.

Fig. 3 is an elevation showing one form I the screw12 appears. y

In order to provide a tight/joint between this liquid being often of. a greasy 'or dis-' agreeable character, I associate with the said cap 7 a sleeve 8, provided with'a lateral aperture 9, and adapted to fit and extend upward to any suitable distance within the outlet pipe 2; and, in order that the flow of liquid through the aperture 9 shall occur in a known or predetermined direction, I prefer to provide for a relative movement between the cap 7 and the sleeve 8, and to provide also a means for restraining or pre venting the rotation of the'sleeve 8 withinthe pipe 2. i

In order to hold the'sleeve'S against rotation in the pipe 2, I may kerf the upper portion of the same in, for example, the manner shown at 10 in Figure 1, whereby the imparting of a slight outward 'bend to the resilient section .11. may serve,.by its frictional engagement with the'interior of the pipe 2, to retain the mentioned parts against relative rotation. Alternatively, I. may employ, for this-purpose, a construction such as is shown in F igure'2', in which the sleeve 8 in provided with a longitudinal slotlO,

through which may project the inner end of a screw 12, seated in the'p'ipe 2 ,and

serving not only to retain the sleeve 8 against rotation, but also to limit the descent thereof when the valve is opened, in the manner shown in F igure2'. vVhen this con.-

struction is employed, ther'user of'my valve may know that theexit of fluid from the valve will occur at the opposite side of the pipe'2" fromthat upon which the head of thecap 7 and the pipe upon which it may be employed, and at the sa'meti'me permit of a relative rotation between the sleeve 8 or 8 and the said cap, as is necessary in applying or removing saidcap, any suitable means may be employed; and for this purpose I prefer to provide a swivelconnection comprising a plate 13, shown as secured by screws 14:, extending through the cap 7 and also through a cupped gasket 15,

secured by said screws and plate; the men tioned swivel connection comprising also a pivot screw 16, seated 1n an inclined plug 17, secured in the lower end of the sleeve 8 or 8 said screw extending through a central aperture in the plate 13, and being provided wlth a head 18 adapted to engage the lower surface of said plate, and being provided also with an adjustable nut 19 and a washer 20, adapted to retain the packing 21; it being understood that the packing 21 is norn'ially secured against rotation and adapted to contact with the inner surface of the pipe 2 or 2 while the gasket 15 is adapted to rotate with the cap 7 and to con tact with the lower end of the said pipe, when my valve is closed, in the manner best shown in Figure 1.

From the foregoing it will be obvious that I have provided a simple and effective slip sleeve valve, especially suitable for use in connection with drain or cleanout openings, and comprising means whereby a tight closure may be effected when desired, and whereby an outflow of liquid may be turned in a desired direction, in order to avoid soiling the hands or clothing of the user of my valve; and also that I have provided a slip sleeve valve which may be manufactured and sold at a very moderate cost, it being, moreover, easily possible either to manufacture and market complete valves of the char acter described or to provide existing outlets with caps and sleeves of the character herein described.

Although I have herein described but one complete embodiment and a modification thereof, it will be understood that various features thereof might be independently employed, and also that various modifications might be made therein without departure from the spirit and scope of my invention,

as the same is indicated above and in the following claims.

That I claim is:

1. In a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said sleeve being provided with a gasket secured at the end thereof and adapted to contact with the interior of said ipe. p 2. In a slip sleeve valve, afixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate.

3. Ina slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured there-1n by a plate provided with a central aperture.

4. In a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate provided with a central aperture and se cured to said cap. I

5. In a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate provided with a central aperture adapted to receive a pivot screw.

6. In a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate provided with a central aperture adapted to receive a pivot screw'extending into an inclined plug.

7. In a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate provided with a central aperture adapted to receive a pivot screw extending into an inclined plug secured in said sleeve.

8. In. a slip sleeve valve, a fixed outlet pipe, a cap therefor, and an apertured sleeve secured to said cap and extending into said pipe, said cap being provided with a gasket secured therein by a plate provided with a central aperture adapted to receive a pivot screw extending through an additional gasket.

In testimony whereof I have signed my name to this specification.

EDWARD HARBERSON.
