b all whom it may concern.'

Be it known that l, ADDISON B. CARLI., a citizen ofthe United States, residing at New York, in the county of New York and State o f New York, have invented a new and useful Barrellfiller, of which the following is a specification.

The present invention relates vto an iinprovement in barrel fillers, and has for an ol ject to provide an automatic.barrelllerfor cutting off the flow of liquid when thebarrel or container is filled to thedesired lheight, and wherein the discharge of thefluid into the barrel is had `from the lower end `of a nozzle, which projects into the bung, or top of the barrel.

Another object of the invention is to pro vide a nozzle, which is detachably mounted on the body of the lillerand which is inter` .locked or dis-engaged fromthe body by the rotation of the nozzle in either one direction, or the other. This object of the invention contemplates the mounting of a float in one side of the nozzle, and providing a concentric connection between the laterally offset float and the body, so that the iloat may be free to rise and fall and control the self closing valve `in the body, and at the same time the nozzle may be readily turned in either direction to remove the nozzle or replace the same.

lt is a further object of the invention to provide a discharge nozzle for barrel fillers, wherein the fluid is discharged from the lowerl end of the nozzle and wherein an ec" centric float chamber is disposed in one side of the nozzle. and has the oaenino thereof through the adjacent side of the nozzle slightly above the lower end thereof, so that the suction created by the outflow of fluid into the barrel will not draw the fluid out of the float chamber to thus prevent the free action of the float. The float chamber is provided with a vertically movable Vfloat which is suitably spaced from the walls of the float chamber to prevent sticking of the float, and providing for its free action.

Other objects and advantages of this invention will be more clearly brought out from the following description of the present preferred embodiment of the invention, the same being disclosed in the accompanying drawings, wherein lligure 1 is a side elevation of the iniprovcd barrel filler.

Referring to these drawings, wherein like parts aredesignated by similar numerals of reference, designates the body of the filler, which is in the form of a valve casing having an intermediate horizontal web 16 suitably apertured, and provided with an upstanding valve seat about the aperture. A valve 17 is adapted to engage the valve seat and be held thereto by Va spring 1S, which surrounds theA upstanding valve `stem 19. The valve stem 19 passes lupwardly into a guide 20 formed vwithin a cap 21 detachably placed upon the upper end of the body 15, and preferably engaging screw threaded relation with the body, as shown in Fig. 2. rlhe spring 18 bears at one end against the valve 17 and at its opposite end against the guide 2O so as to normally urge the valve 17 against the valve seat. A. suitable inlet nipple 22 leads from the rear side of the body 15 `above the web 16, and is adapted for connection with a flexible hose, or the like, through which liquid is conveyed to the filler.

The stem 19 of the valve projects downwardly from the valve 17 through the opening in the web 16, and is seated in a stepped bearing or guide 23, upstanding from the lower wall of the body 15. The guides 20 and 23 hold the valve stem 19 in true vertical alinement, so as to insure the true seating of` the valve 17 on the valve seat, and to prevent lateral displacement of the valve 17, when operated by the mechanism hereinafter described. The lower end of the valve stem 19 has an outstanding flange or rim 24 constituting Van abutting shoulder against which the finger 25 is adaptedto strike for raising the valve stem 19 and opening the valve 17. The finger 25 is fixed upon a transverse shaft 26 extending horizontally and' transversely through the body 15 behind the valve stem 19. As shown in Fig. 4,

one end of this shaft 26 is journaled in a 'bearing 27 in the form of a boss projecting inwardly from the side of the body 15, and the opposite end of the shaft 26 is journaled in aninwardly projecting sleeve or boss 28 preferably integral with a detachable ycap 29 fitted in the opposite side of the cas- Y' turned to raise thefinger 25 against the tensionV of the spring 18. The outer end of the VVshaft 26 has a rectangular shank 30 lying adjacent to the sid@J of the body 15 and adapted to receive the angular socket 31 of an arm 32. As shown to advantage in Fig. 4, the arm 32 has a flat inner side adapted to lie close against the side of the body 15, and as shown in Fig. 1, to move against a flat segmental guide or bearing 33 projecting laterally'from the body l5 and terminating at its rear end in a stop 34. The stop 34 projects laterally and outwardly from the guide 33 and engages the rear side of the arm 32 when the latter is in its lowermost position, as shownY in Figs. 1 and V4, and in position to admit the seating of the valve 17 under theV action of the spring 18. A retaining nut 35 is detachably mounted upon the threaded outer extremity of the shaft 26, the nut bearing against the angular socket 31 of the operating arm to hold the latter on the shank 30 of the shaft.

The lower end of the body 15 is offset forwardly as at 36 and is internally threaded at its lower end to `receive a tubular nozzle 37, which is detachably mounted upon the body 15 by reason of its threaded engagement therewith. This nozzle 37, as may be best seen from Figs. 2 and 5, has an eccentric float chamber 38 mounted in one side thereof and extending substantially throughout the entire length of the nozzle 37, although the length of the oat chamber is immaterial. The float chamber is closed at its lower end by a plug 39 threaded into the lower end of the chamber 38, as shown in Figs. 2 and 7, to entirely close the lower end of the fioat chamber, so that the fluid passing downwardly out of the nozzle 37, through the crescent shaped outlet thereof, cannot by suction disturbthe contents of the float chamber. The outer side of the float chamber 38 preferably merges into the adjacent siderof the nozzle 37, as shown to advantage in Figs. 6 and 7, and this common side of the float chamber and the nozzle is provided with one or more openings 40 adjacent the lower end of the nozzle 37 to receive iuid from the barrel when the latter is nearly filled, and to admit the Huid to the fioat chamber. Within the chamber 38 is a float 41. As shown in Figs. 2, 3 and 6, the float is relatively small in diameter, as compared with the inner diameter of the chamber 38, so as to provide a space between the oat and the inner wall of the chamber. The float is held concentric within the chamber 38 by guides or spacers 42, in the form of wings or lugs outstanding radially from at least three sides of the float, and being equally spaced thcreabout so as to hold the float centrally in the chamber, as shown in Fig. 6. The float is thus permitted to movefreely up and down within the chamber 38, without liability of sticking or producing undue wear or friction on the float and chamber. The float 41 is connected by a suitable connecting element 43, such as a wire or rod as shown, with a latch lever 44 pivotcd upon the body 15 to control the operation of the self-seating valve 17. The rod or connecting element 43 extends down into the nozzle 37 and in order to protect the rod 43 from contact with the fluid passing down through the body and nozzle, an inclosing tube 45 is employed which projects downwardly from the body 15 and opens through the body thereof immediately beneath one end of the latch lever 44.

In order that the nozzle 37 may be turned either to the right or left, and rotated a considerable number of times, to entirely detach the nozzle from threaded engagement with the body 15, or to bind the nozzle tightly in the lower end of the body 15, it is essential to so arrange or dispose the connection be- A With:this purpose in view, 4the present invention provides .an upstanding *socket for nipple 46 onthetopofitheiiioat chamber 38,

whichsocket 46 islocated concentric to the nozzle-37. Theconnecting wire orelement 43 is -securedto thesfloat V41 atone side thereof in verticalalinement withithe socket 46, as shown in iFig.12fo;t thedrawings, .and is secured to the lioat preferably byan eye 47, which passes `fthrough one Vof the wings or radiating spacers 42 atthetupper end of the float 41. The socket 46 is adaptedlto slid ably and rotatably receiveiithe lower end of the protecting tube 45 therein. rlhe tube 45 is threaded at its upper end into a threaded socket 48 'opening Adownwardly 4through the upper wall oi the ofset portion 36 of the body. Thus, when the nozzle 37 `is turned-to screw up or unscrew the same, the

ears provide a transverse Ipassage or channel to receive therein the outer-long arm of the latch lever 44. The lever 44 is ulcrumed upon a pivot bolt or pin 51 passing transverselyy .through -the outer ends of the ears 49 and 50 to dispose the outer-end of the latch ylever immediately over the socket 48 and tube 45, whichis'litted therein. This outer end of the latch lever is hooked or arched downwardly as Vat 52 to-receive thereover an upper eye 53 formed upon the upper end of the connecting element or wire 43. Thislatchlever 44 is provided with an inner horizontal arm 54 adapted to support the counter-weight 55, and also has a depending verticalarm56 having a supporting shoulder 57 on its lower end facing outwardlyto receive thereagainst the inner edge of the valve controlling arm 32, as shown in dotted lines in Fig. 1, and in vsection in Fig. 3.

The counterbalancing weight is adjustable so as to vary the eil'ective Vweight of theoat 41 when surrounded by thefluid The counter-weight 55 may be of any desired shape, form or size, but for the purposes of illustration,is shown in thepresent instance, as comprising a lat'relatively thin disk pivoted at its centraliportion upon the top flat `Jface of the horizontal arm 54 of the latch lever by means of an adjustable screw 58 beneath which is placed a. spring washer 59, the ends of which are oiset romone another out of the planeofithe washer to yieldingly holdthe disk against the arm 54. Oneedge ofthedisklis provided withthe fbody of :the weight, .the same 'being in the form of a substantially semi-circular block or thickened `flange upstanding ,from the disk, and being of sulicient size to counterbalance the vfloat 41 to the desired extent. The outer edge of the ldisk andthe outer Aface vof the body `portion of the weight 55 indotted lines the innermost position of the weight 55, showing that the weightis disposed substantially in the vertical plane of the pivot 51 of `the latch lever, so that `the e'ective `weight of the horizontal arm 54`is practically eliminated.

The depending vertical arm 56 of the latch lever carries Vtherein an anti-friction roller 60, which projects slightly above thc supporting shoulder 57, and is adapted for direct contact'with the opposite faces and `the inner edge offthe valve arm 32. It will be noted that the lower outer side of this arm 56isbeveled.inwardly and downwariilly so as to expose a substantial portion ot the periphery of the-roller 60 and to bring the. roller 60 into conta ct with the arm 82, when the latter is swung up to open the valve 17. VVhenthe device is set in the open position,v the parts assume the positions shown in Fig. 3 oflthe drawings. In this arrangement cit the parts, the lloat 41 `holds the latch lever down inlocked positionto secure 'the roller 57`beneath the arm 32 and hold itin raised position against the tensionof Vthe spring 18. As soon as the float 41 is raised a suililcient distance, the weight 55 advances the lever 44 during `the upward movement of the float'ito take up any slack therebetween, and swings the supportingarm 56 inwardly a suili'cientdistance to admitthe release ot the `valve arm 32 from the shoulder 57. Then this condition arises, the arm 82, under the action of the spring 18, presses the roller 57 down to retract the latch lever, the anti-friction roller admitting of the easy operation of the parts and oitsctting undue Wear betweenthe shoulder 57 and the inner edge of the arm 32. Thus, as the friction is reduced, the action of the latch lever a quick one, so that the arm 32 is quickly re leased and the valve 17 immediately closed uponthe raising of the float to the predetermined height. The counter-weight 55 may be adjusted into various positions to regulate the desired counter-action uponthe float 43to increase or decreasethe effective weight of the latter, so as to admit of the line adjustment of this improved barrel filler, irrespective oi" the specific gravity, or

4other characteristics of the liquids, which are passed through the'device.

As shown in Fig. 2 of the drawings, the nozzle 37 is preferably provided with au adjustable support 61 in the form of a split sleeve having outstanding ears 62 at one side through which is passed a clamping bolt 63 for contracting the ears and binding the sleeve 61 on the nozzle. Depending legs 64 radiate from the sleeve 61 and are adapted to rest upon the head 65 of a barrel 66. The legs 64 are spaced about the nozzle to admit the insertion of the nozzle downwardly through a bung, or an opening 67, in the head 65 ofthe barrel, and to support the nozzle at the desired height through the opening 67.

From the above description, taken in connection with the drawings, it is believed that the operation of the device will be clearly understood, for, when the parts are in set position as shown in Fig. 3, and in dotted lines in Fig. 1, the valve 17 is open so that the fluid is permitted to pass freely from the inlet nipple22, through the body 15,-and outwardly through the lower crescent shaped end of the nozzle 37. The tubel 45 prevents the liquid from entering the float chamber at the top thereof, the lateral :disposition of the'openings 40 in the side of the float chamber prevents the suction of thev outflowing liquid from effecting the con tents of the lioat chamber. The roller 60 supports the arm 32 in horizontal position at the forward end of the guide 33 to hold the linger 25 up against the abutment 24, and supports the valve 17 above the seat against the tension of the spring 18. As soon as 'thefloat 41 is raised sutliciently to relieve the outer end of the latch lever 44 of the weight of the float, the weight 55 swings the latch lever 44 upwardly at its outer end and moves the shoulder 57 from beneath the arm 32. The arm 32 now forces the roller 60 inwardly from beneath the arm, the roller reducing frictional contact between the arms 56 and-32, and admitting ofthe quick action of the arm 32 in swinging downwardly and backwardly to seat the valve 17. Should it be found necessary to adjust the counter-weight 55, the same may be turned by hand about its pivotal support 58, so as to dispose the center of gravity of the weight 55 at the desired distance from the pivot pin 51 of the latch lever.

When it is desired to gain access to the interior of the device, or to pack the same for shipment, or for any other reason to se arate the nozzle from the body 15, it is on y necessary to turn thenozzle upon the body .to unscrew the nozzle therefrom, the

float connection with the latch lever being concentric to the nozzle and the body 10, so that the parts will not be dislodged, and will nothave to be removed prior to the turning of the nozzle. When the nozzle is unscrewed, it is only necessary to draw the same downwardly, so as to remove the socket from about the lower end of the tube 45, and withdraw the connecting element 43 from the lower end of the tube to entirely disconnect the Vnozzle from the body. It is, of course, understood that prior to the turning Vof the nozzle, the connecting wire 43 must be disengaged from the hooked end 52 of the latch lever.

In the present practical embodiment of the invention, from which the accompanying drawings have been made, the latch lever or pawl 44 is provided with spacing bosses 68 at its opposite sides and through which the pivot pin 51 passes. lThe bosses take up the frictional contact between the lever 4-4 and lthe ears 49 and 50, and serve to steady the lever in its swinging movements.

It is, of course, understood that various changes and modifications may be made in the above specifically described construction, without departing fromthe spirit of this invention and being restricted only by the scope of the following claims. I I
