ters with port 17 throughout the reciprocation of the piston.

A valve cage 2l is exteriorly threaded upon its lower portion and screwed into the tapped bore of the piston, before mentioned. The upper portion or" the valve-cage is centrally bored, at 22, to torni a guide forthe valve stein, hereafter to bedescribed,y and j the 'lower portion of the valve cage is provided `with the enlarged bore 23 which `conia retainingnut 28 screwed 'upon the lower eX- tended end of the valve cage. The lower edge of valve-cage 2l is7 preferably, beveled, at 29, 'to forni a seat for a valve 30fcarriedupon the lowerend of a 'stem 3l, which extends upwardly through bore'22 of the valve cage and above the top of cylinder 16. N ear theA top ofthe valve stem by nuts 32'is secured a colyso lar having a laterally extending arm A spring' 34 positioned around the valve stein and between the top of the valve 'cage and the lower nut 32-maintains the valvenornially but yieldingly'in closed position. The; Y outer end iol: the'lateral arin`33 is provided rwith a vertically disposed rod 35 which is guided in a hollowfembossmentB extended from the wall ofcylinder 16. rllhe rod 35 is provided lwith, laterally elxteiiding stubs 37 Iand 38 which extendthrough .a slot .'39

. in the side ofthe hollow einbossmentdand upon the ends of :the stubs are provided anti-friction rollers 4:0. Secured upon suitable brackets dl extending from the verti-A cal members 5 ofthe frame isra circularcain track 42 which passes between the anti-frio- -tion rollersLiO of they stubs 37 and 38, here- 4totore described, and said rollers engage, re-

spectively, the top and bottom of the circular cani-trackn rlhe cani-'track secures Vits action through the instrumentality of vertically inclined portions 43, which, when `en-V gaged by rollers 40 will lower and elevate the guide rod 35 and ithe `valve stein 31 assembled therewith, thus opening and closing valve 30. y

Between port 20 and the lower edge of the piston is an annular groove 44 in which is mounted suitable, packing 45.

The operation oi my devices is as follows :--The rotation of shaft 7, together with table ll and tanlr l5 carried'therebywill secure therreciprocation of piston19`in the cylinder 16 through the instrumentality of rthe circular cani track, rod 35. and stubs and 38. When the packing` or sealing gasket 9a7 comes in Contact. with the top of the container the further descent of piston 19 will be arrested, but the-valve stem 3l through the compression of spring 34 continues downwardly, thereby unseating valve 30 andpermitting liquid to flow into the container until the'latter is filled.y Upon the upward reciprocation of valve stein 3l 'g'asl'ret 27 is maintained in contact with the top of `container a through the action of spring' 3e until valve-30 is seated when the further upward movement of valve stein 31 vwill elevate thev piston thereby unseating gasket Q7 from the top' of the can and releasing the can. 1

The size the projecting portion oit collar 28 and valve 30 is so proportioned that when it is withdrawn. from the can the can will not be overiiowed, but willll't-e sutliciently i'ull to suitablyjreceive the closure without thegnecessity oli' .removing Huid therefrom. 'From the foregoing description, talreiiin connection with the drawings, it will be observed that-l have provided a simple 4mechanism for iilling containers with fluid `which may be adjusted for different sizes of containers; which obviates the vertical nieve- -nient or shaking` or the containers atei'jthey have received vthe liquid; `which'automatically -tales care of ordinary diiierences in heights of containers; which fills the` `containers just full enough but not too full; and which will not operate to spill and waste the Huid when no container is in `position to receiveV the saine.

lWhat l claim as newvis :e y l l.l In acan lling-device, a uidcontainer, a cylinder having communication therewith, a piston reciprocable vwithin said cylinder, a valve mounted in the bottom of said piston, a stem on said valve having a `projection ,thereon,a spring interposed Ibetween said piston and the projection-.on said stem for Y yieldingly maintaining said valve normally nieve-d to 'engage a container and the tt'iirfther movement valve.

2. Fluid dispensing instrumentalities coinprising a cylinder, a hollow piston reciprocable in said cylinder, said piston having'a port in one end, a valve .controlling said port, a stem arising .therefroni, yielding means comprising a spring operating between said piston and said stem for -maintaining saidgvalve normally closed, and' means acting Athrough said stem Jor 'reciprocating it with said piston whereby said valvereinains closed until the forward'movement of said piston is arrested.

3. 'Fluid dispensing instrumentalities comprising a cylinder, a piston reciprocable within saidk cylinder; said piston'having a port therethrough, a valve controlling said port. a stem having a projection arising troni said valve, a spring interposed between said of said device unseats said piston and the 4projection on said stem, means acting through said stem for reciprocating it With said piston, and sealing means carried by said piston for engaging a container.

4. n a can filling machine, a luid tank, and devices for controlling the flovv of fluid therefrom to the can to be filled comprising a cylinder in communication With said tank, ahollow piston reciprocable in said cylinder having a port in one end, a valve for controlling said port, a stem arising from said valve, a spring operating between said stem and said piston for maintaining said valve in normally closed position, an element carried by said piston adapted to seal the can to be lled, and means co-acting With said stem whereby said piston is moved to seal the can and the further movement o'l said means open said Valve.

A can filling machine comprising a fluid tank, a cylinder in communication With said tank, a piston reciproeable in said cylinder and having a discharge port, a can sealing member surrounding said port, a valve seated insaid port having a stem eX- tended outside said cylinder, an actuating rod connected to said valve stem and having laterally projecting members, a camtrack positioned between said lateral members, and means for causing a relative movement between said tank and cam track.

6. A can filling machine comprising a rotatable {iuid tank, a cylinder in communication with said tank, a piston reciprocable in said cylinder and having a discharge port, a can sealing member' surrounding said port, a valve seated in said port having a stem extending outside o said cylinder, an actuating rod vconnected tosaid valve stem and having laterally projecting members, a stationary cam track positioned between said lateral members, and means tor rotating said tank whereby said cam track is caused to move saidlateral members and thereby seal the can to be illed and open said valve.
