. To all whom it may concern Be it` known that I, STANISLAW WILINSKI,

citizenv of Poland, residing at Bay City, in the county of Bay and State of Michigan,

have invented certain new and useful lmrovements in Aperture-Cleaning Syringes, of which the following is a specification.

This invention relates generallyvv to aliquid discharge device, having more -par-. ticular reference to a combination of av syringe element with a discharge nozzle on a pipe or other device conveying a continu'-r ous stream.

The invention has for an object to pro.

vide a device of this kind whereby momentary increase of pressureof the discharged fluid over that of the continuous stream may be obtained, the invention being suitable for use in cleaning out clogged openings of any kind, such as the overflow'openings of sinks,

. wash-basins, wash-tubs or the like.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, andto the appended claims in which the various novel features of the invention `are more particularly set forth.

Figure 1 of the drawings is an axial longitudinal sectional view of a device embodying the invention, showing it applied to clean the overflow openings of a wash-basin.

Fig. 2 is'a side elevation of the device.

Figs. 3, 4 and 5 are central sectional views of modified forms of nozzle tips.

As here shown my improved device coinprises a cylinder 10 which may have a suitable lining element 11 therein and is provided at its forward end with a nozzle cap 12 screwed thereon, the rear end being closed by a plug 13. A pair of nger-grip rings 14 are mounted on the rear portion of the cylinder.

Approximately midway of its length the cylinder 10 is provided with a flanged opening 15, the ila-nge 16 whereof presents an internally threaded socket for the reception of one end of a nipple 17 whose opposite end may be exteriorly conjugated and adaptec for insertion in the end of a rubber pipe or hose 18, a splitcollar 19 being employed to clamp the hose end on the nipple 17. The opposite end of the hose 18 may be connected to a faucet or other source of water supply.V A

A plunger element 22 is located in the cyl- Speccationvof Letters Patent.V Fgttted Bec. 13,

inder 10, vbeing ofapproximately lone-half the length of the latter, with its' forward end-y projecting; slightly .beyond the opening 15 when the plunger is retracted. .This

plunger -22 is chambered'or *hollowed' out from its front end rearwardlyas at 23 and a longitudinal slot 24 is formed inthe Wall of the plunger and communicates with the interior thereof. The-plunger 22 is adapted to be operated by means of a handle 25 fixed on a ring 26 freely surrounding the cylinder 10, thisA ring having ,an inwardly projecting screwj27 vwhich is threaded laterally into the solid rearend of the plunger. To yaccommodate this screw 27 and permit ofmovement of'the'plunger 22 with the S1015` l 24 in or out of registry with-the opening 15 f in the wall of the cylinder 10, the latter 1 provided with a U-shapedjslot the two legsl of which, indicatedv at 28 and 29-respectively, are spaced circumferentially substantially ninety degrees apart and extend forwardly from the connecting transverse portion 30 of the slot. The plunger 22 is normally held in its rearmost position by a coiled expansion spring 31 surrounding the cylinder and bearing at opposite ends between the ring 26 and a flange 32 on the cylinder.

In Fig. 1 of the drawings I have shown my improved vdevice with the nozzle tip 12 directed toward the overflow openings 33 of a wash-basin 34. Assuming the hose to be connected to a faucet from which the water pressure is not very strong, the plunger 22 being in position with the slot 24 register'- f ing with the opening 15. The pressure can' be momentarily increased by hand by quickly pressing the plunger forward with a pressure greater thanthat of the flowing water, the inertia of the water flowing through the hose 18 acting to resist the tendency of the water to flow backward therethrough when the increased pressure is applied to the plunger. Should it be desired to shut off the opening 15, the plunger canbe turned until the screw 27 registers with the slot element 29 and forced forward.

The device may be supplied with the different types of nozzles shown in Figs. 3,

`4 and 5 which may be employed as desired.

Having thus described my invention what l claim as new and desire to protect by 'Let-V ters Patent of the United States is as follows:

1.A device of the class described comprising a cylinder, having an intake opening beeov tween its ends, a discharge nozzle on said cylinder, a chambered plunger within said cylinder having a slot in its side wall and having its rear end closed, and means whereby said plungerV may be advanced with the said -slot'in or out of registry with the said opening.

2. A device of the'class described comprising a cylinder, having an intake opening betweenl its ends,.a discharge nozzle on said cylinder, a chambered plunger within said cylinder having a slot in its vside wall and having its rear end closed, and means whereby said .plunger may be advanced with thesaid slot in or out of registry with the said opening, said means including a handle element projecting through a U-'shaped slot in the wall of the cylinder. f

- 3. A device of the class described comprising a cylinder having an intake opening between its ends and a U-shaped slot the legs of which extend forwardly, a chambered Yplunger. in said cylinder having a longitudinal slot in its side' wall and havingA its rear end closed, a ring surrounding said cylinder, a member projecting inwardly from said ring, through the said U-shaped slot to fix the ring to the said plunger and adapted when engaged'with the different legs of vthe said U-shaped slot to position the slot in the plunger respectively in or out of registry with the said intake opening, and a spring bearing against said ring.

4. A device of the class described comprising a cylinder having an intake opening approximately midway of its length, and a ger, a handle fixed on said ring, a screw projecting inwardly from said ring to said plunf ger through the said U-shaped slot and fixed to said plunger and adaptedrwhen engaged with the dierent legs of the said U-shaped` slot to osition the slot in the plunger respective y in or out of registry with the said intake opening, and a coiled expansion .springsurrounding said cylinder and beare ing against said ring. f

In testimony whereof I have affixed my signature. Y t
