.4 Claims.

, 'The object of the present invention is to provide a machine which will receive either cans or drums, which will feed said containers continu 'ously in a circular path with each container brought into registration with one of a plurality of filling nozzles, the latter communicating with metering devices of a known type for filling the containers with a measured quantity of fluid. As each container is brought to the beginning of the circular path an appropriate filling nozzle automatically descends into the container, this being done with respect to each of a succession of containers, so that a plurality undergo filling until they reach the end of the circular path. At this point the nozzles are retracted from the contain- .erS, in succession, and the containers move away for packing or direct shipment. A characteristic of the invention is that the spacing and registration of the containers in the circular path is effected by the means which moves them, such means being pusher arms. There are-two sets' of pusher arm's, each arm of a set-being telesco ic, one set heing for drums or other'la'rge containers and a second and uppermost setbeing -'for cans or other relatively small containers. *Each set of arms lies above its own support for the'com t'ainers. The supports are trackways in "the term of elongated rollers, inwardly tapered, the entire upper tra'ckway being-removablein nrd'er thatthe lower trajckway alone mayiunction with respect todrums or large containers.

The invention will be described with reference to theaccompanying drawings, in which:

Fig. 3 is a horizontal sectiononthe line 33, Fig. 1;

Fig. 9 is a detailed fragmentary view partly in section showing the strap mounting for the pusher arms; and

.2. "Fig. '10 is a plan view of the structure shown in Fig.9;

Rererring to the drawings, I have shown at l a plurality bi vers s-1 standards which support 5 angle rons-z which pivo llycarry between them a plurality of tapered rollers 3'. As shown in Fig. 8 these rollers are preferably formed of tubing and an agile! projects ate'ach end thereof after passing through i'sks 5. The angle irons -2 are bent to o rrn' a c'ircul r partly around a rotary tuloiilar axial ine her 4. at one end the assemlily of ca e ne bus 2 for-msfan entrance length and the opposite end forms an exit len'gth, as sh-own'm'ore particularly inFigs. 2 and 3.

The tubular standard 4' is, as shown in Fig. 4, provided with a flangd b'as e at ta: closed-by a t1iat)la ifagnfi 5 and" thence mounted upon the flanged upper end of'atiiloular dependin'g' e'xten sionfi which enters thelearing' boss-'11: of a gear box '7. fI-h redii'cdlowfendof member-G of the tubular standard Wcarriies a worm wheel 8 en}- gaged-by a worm 9 (Fi-g'j 4?.

For inoving drums or other relatively large contain er s ,on the rollers oft-lie lower "trsekway, there s manages the'tubul'a'ir standard a a sleeve l9 7 'pr ease pluralityof'tubii- ,larcarr'iersjflgc t ible conduit 28 at the end of which is a nozzle 29, each nozzle being supported by a chain or other flexible holder 30, leading downward from an endwise movable rod 3| mounted in a bracket sleeve 32. Carried by the lower end of each rod 3|, is a roller 33 wh i ch rides upon a camtrack 34 supported by standard I. At both the entrance and exit portions of the cam-track it has a high section. That is to say, when the containers reach such position that they are initially and successively engaged by the pusher arms, the respective engaging pusher arms will lie immediately over the high point of the camtrack and immediately adjacent a nozzle which will be held above the can or other container. However, as the container is moved further the roller of the appropriate rod 3| moves to the lower area of the cam-track and the nozzle is dropped from the position of Fig. 6 to the position of Fig. '7 and hence into the filling opening of the container. The appropriate metering valve will be set to institute the flow of oil or other fluid at this point.

As shown in Figs. 9 and 10 the attachment of the tubular members of the pusher arms to the ring 21 may be by means of straps 35, and adjacent the straps, each tubular member 20 may be provided with a set screw 36 for holding the appropriate rod 22 in either projected or retracted position. Also, it will be noted from Fig. 1 that the nozzle holding rods 2| are preferably formed with yoke ends so as to embrace and provide guiding surfaces for the flexible conduits 2B. When small cans or other containers are to be filled a detachable trackway consisting of angle irons 2x, rollers 3x and supporting arms In: is employed. The lower ends of the supporting arms Inc may be forked to receive the bolts 38 by which the upper trackway may be detachably held upon the angle irons 2 of the lower trackway, although the inner supporting arms In: may, as shown in Fig. 4, rest directly upon the cam-track 34.

For cooperation with the upper trackway there is provided an upper pusher assembly consisting of the hollow tubular members 20:1: carried at their inner ends by a sleeve or collar I93: on standard 4 and carried at their outer ends by a ring 2hr. In the embodiment shown the ring 2L1: is but a spacer member for the pusher arms, but it may be arranged to afford a positive support therefor. Each hollow member 209: telescopically receives a pusher arm 20:.

In the operation of the machine with respect to large containers such as oil drums, the drums are successively moved forward on the rollers 3, Fig. 2, at the entrance end of the trackway as shown by the arrow on the upper portion of Fig. 2. Each container will be met by one of the pusher arms 22 which, as shown in Fig. 3, lies adj acen't one of the nozzles 29. In the filling of the large containers the upper trackway with its rollers 31: will have been removed and the pusher arms 2211 will have been retracted. The said large containers will be received within the circular path of the trackway while the appropriate nozzles are held by the high point of the cam-track. In a short, continued, movement of each container a nozzle will be dropped into the filler opening so that the pre-set metering valves may begin the filling operation. The filling proceeds in the slow movement of the appropriate containers until they reach the exit end of the trackway whereupon the high point of the cam-track is utilized to raise the nozzles in succession and the containers are discharged.

It will be understood that various modifications may be made in the form and arrangement of the. elements constituting the embodiment illustrated in the drawings without departing from the spirit of the invention.

Having described my invenion, what I claim and desire to secure by Letters Patent is as follows:

1. A can and drum-filling machine, consisting of a tubular standard and means for rotating the same, a platform embracing and moving with the standard, a plurality of metering valves carried by the platform, a manifold provided by the standard and communicating with the metering valves, said manifold being adapted for communication with a fluid supply, a flexible conduit leading from each metering valve, each conduit having a discharge end, means applied to each conduit and comprising a push rod for raising and lowering the conduit, vertical sleeve members connected to the tubular standard and rotating therewith, the sleeve members receiving said push rods, propelling rods extending laterally from the tubular standard and rotating therewith, a trackway for cans and drums, said trackway at least partially surrounding the tubular standard and below said propelling rods, and a second trackway having elevated and relatively depressed sec tions with which the push rods successively engage.

2. A can and drum-filling machine constructed in accordance with claim 1 in which the tubular standard is closed at its base section and is formed with upper lateral feed ducts leading to the metering valves, the interior of the standard having the function of a reservoir and, with said ducts, acting as a manifold.

3. A can and drum-filling machine constructed in accordance with claim 1, in combination with a plurality of axially directed sleeves projected from the standard and receiving said propelling rods.

4. A can and drum-filling machine constructed in accordance with claim 1, in combination with a trackway supporting frame, upper and lower sets of axially directed sleeves projecting from the standard, such sleeve receiving one of said propelling rods, and means on said trackway supporting frame for mounting a second trackway intermediate the two sets of said sleeves.
