ca'singfor receptacle toa delivery-port, spout or conduit, andparticu'larly to control such v i l by ans h h n TP F f pl'oy alternate suction and compression.

"This objectI have attained by the'means which ar hereinafter described and claimed, andwvhich are illustrated the accompanying drawings, and in which similarst'rucltures are indicated by the same numerals.

Insaid'drawings, Fig. 1 isa ve'rtical cenimproved means for "controlling 'itsffluid delivery, some of'the elements being shown "in elevation. Fig. 2 is a detail cross section on "the broken .line 2 2 of Fig. 1 of the the piston-valve being shown in elevation. Fi '3 is a cop plan of-the valve-casing.

fineexa'mple whiche'mbodies my improveme'nt's is that which is illustrated in Figs.

1 to '3 iiujlusive, being an oil-can adapted for manualfactuation of its controlling piston-valve. The oil-can'f8 has communication at the diminished top with the depending neck 6' of a horizontal casing 3 and its included cylinder 2 containing' a conforming reciprocatory pistOnQvalve' "1. An open ended tube 7 has its uppe'r e'nd fitted in said neck to depend 'at an inclination toward the bo ttoin of the can. The lower end of the neck 6. is widened at 20 and \velded or brazed to the open top of the can. The numeral 4 denotes a spout mounted in an annular seat 21 on the top ofone end of the casing 3 and communicatingby way of the delivery-port 5 with the forward part-of the casing which contains the cylinder 2, the latter being of'slightly less diameter than the diameter of the main casing to the rear, the rear open end of which hasas'crew-cap 13'provided with a central hole to receive the plunger stem 14 having an outer terminaldisk 15.

Upon the top of the casing 3 at the rear is an upwardly projecting curved finge'r-,

hold 16, while below said casingis alooped handle 17 on the oil-can 8 whose upper part is crimped inwardly to provide a smaller finger-hold 18 whose outer interval is filled 'by a stifiening pie e 43, 'whe'reby 1 1,616,634 r TED E-S ENE when the handle 17 is grasped, the forefinger of the user may be "hooked abodt-the up'perfinger-hold 16, -and the finger neiit thereto inserted-in 'thefin er-hold 18, givjing a secure grip and perl ect 'm'a'nual con-v M1 tothe user While th'e'thum'b on the same hand is'used topres's 'u pon'th'e disk 15 to push it reward-1y in the "operation of "the piston-valve 1.

' The piston-valveflisa hollow or' c'upped cylinder in shape with its open end di- "ii 'ini shed at 59,-this diminished annular =part serving as a stop against the abuttin'g end wall of the eyunaer to limit the movement v I V I l softhe valve intliatdirection. ee section of a'n'oil-can equipped withm-y A iplunger head 12 is mounted within th on the end of the-stem 14;, having elastic packing "toeffec't' atight joint. r

the'casing by suction draws to the rear the valve 1, and causes suction 1n the cylinder 2 and the tube 7, oil rising by Way of the .tube into the neck 6 and passing thence through the pair of side ports or passages 19 (see Fig. 2)'into the casing 3. The'annular space around the diminished part 9 of the valve gives the requisite clearance for the oil .to the ports 19 when the valve 1 has moved to the rearsufliciently. This fills the hollow casing 3' with oil. Subsequent compression of said spring returns the valve 1, because the push of theplunger is transmitted to the valve by the oil in the cas- 1 spi'ingieacts towa'rd the right or rear push: ing the plunger-head 12in that direction,

and the partial vacuum thereby caused in ing to' return the valve. In its return to the front, the rear end of the valve uncovers the delivery-port 5 and oil is ejected of the latter,

perforate plunger 'l'rom the casing therethrough into the spout 4. V 7 Having described'my invention, What I claim as new, and desire to secure by Letters Patent, is:

1. A valvular device, comprising a valvechamber having an interior cylinder inter mediate its ends and an enlarged springbarrel opening into one end of the cylinder, the valve-chamber having a port positioned Within said cylinder intermediate the ends an unconnected imperforate floating plunger reciprocably fitting said cylinder and having that end opposite the spring-barrel diminished to be limited in itstravelby impact with the facing end Wall of the valvdchamber, and a coiled spring mounted in said spring-barrel to have one terminal stopped by a shoulder between the cylinder and spring-barrel and the terminal bent diametrically inwardly to serve as a 'lnnlting stop for said plunger, and means for releasably compressing said spring including means for producing alternate suction and pressure on the plunger.

2. A valvular device, comprising arvalvechamber'having a port at one end and having'a cylinder intermediate its ends, and

having its end' part opposite said port en-' larged at a shoulder to serve as a spring-.

barrel and suction chamber, a coiled spring in said spring barrel having one end 00- casionally engaged with said'shoulder and having a terminal bent inwardly, an iminsaid spring-barrel fitting it and occasionally engagingthe outer end ofsaid spring, said spring-barrel having an apertured removable end-closure, said plunger having a stem projecting through said apertured end-closure, an unconnected imperforate floating plunger fitting said cylinder reciprocably to control the delivery 7 of said spring-barrel into' the cylinder, said cylinder having a port intermediate its ends, and the last-mentioned plunger controlling piston in of said cylinder,

, piston.

said port, being stopped at one limit of its travel by and said last-mentioned plunger the inwardly projecting terminal of said end-closure, said plunger having a stem projecting through the .apertured end-closure, an unconnected lmperforate floating plunger fitting said cylinder reciprocably and stopped at one limit of its travel by the in -e terminal of said spring, said Wardly turned cylinder having a port intermediateits ends controlled by the last-mentioned plunger,

and the cylinder'ivall having at opposite 'sides longitudinal recesses separated from said port to serve-asconduits communicating and between the ported end of the valve-chamber V and said intermediate port at a certain position of the last-mentioned plunger.

4:. A! device of the character'described,

characterized by the inclusion of a differential cylinder, an unconnected floating one dilierential part of said cylinder, a plunger in the other differential part and a resilient member intcrn'rediate said piston and plunger adapted to alternately serve as an elastic cushion for the plunger and as an end-stop for the Signed at Waterloo,.I oWa, this 19th day of June,1923.
