JOHN OFTEDAHL, OF HANLEY FALLS, MINNESOTA,

BOTTLE-FILLER.

To all whom it may concern.

Be it known that 1, JOHN Or'rnonnn, a citizen of the United States, residing at Hanley Falls, in the county of Yellow Medicine and State of Minnesota, have invented certain new and useful Improvements in Bottle-Fillers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in bottle fillers and particularly to portable bottle fillers for use in filling bottles in cases; and, to this end, generally stated, the invention consists of the novel devices and combinations ofdevices. hereinafter described and defined in the claims.

illustrate the invention, like characters inclicate like parts throughout the several-views.

Referring to the drawings,

Fi 2 is a detail view in sectiontaken on the l1ne 2-2 of Fig. 1;

Fig. 3 is a fragmentary detail view, partly in elevation and: partly in central vertical section illustrating the lower end of one of the filling tubes, on an enlarged scale; 1 and Fig. 4 is a detail view in section taken on the line 4-4 of Fig. 3.

The numeral 1 indicates a flexible liquid supply pipe or hose leading from an elevated storage tank or other suitable source of supply, not shown. This pipe 1, if desired, may be arranged to form therein a siphon-acting portion, as in my co-pending application filed February 16, 1916, under S. N. 78,589, entitled Bottle filler. The delivery end of the pipe 1 is telescoped onto the receivingend of a tubeextension 2, integrally formed with the member 3 of a two part cylindrical head, the other member of nected, the former-onto the latter, and the member 4 has integrally formed therewith a pumpcylinder 5. The tube extension 2, head members 3. and ,4 and pum cylinder 5 are all axiallylalined Mounted within the pump cylinder 5, is

members of the head 3-4 in difierent axial adjustments, the member 4 is longitudinally spllt at its inner end and provided with a pair of depending lugs 11, in which is mounted a thumb screw 12 forlcontracting the member 4 onto the member 3. A liquid l j tight joint is'formed between the two head In the accompanying drawings, which j members 3 and 4, by forming in the member 3 annular grooves 13 and packing the same with Vaseline, or other suitable'substance.

On the under side of each member of the head 3-4, is a stufling box equipped nipple dividers. Normally, the filling tubes 15 are yieldingly held in extended positions by coiled springs 16 compressed between the stuffing boxes on the nipples, 14 and annular shoulders 17 integrally formed'in intermediate portions of said filling tubes.

Surrounding each filling tube 15 and slidable longitudinally thereon, is atapered bottle sealing stopper 18, adapted to be inqserted art wayinto theneck of a bottle into w ich the respective filling tnbe15 is "inserted. Set screw-equipped collars 19 are mounted on the filling tubes 15, above the stoppers 18, are engaged thereby and hold said stoppers in their difiz'erent adjustments.

Extended axially through each. fillingtube 15, is an air escape pipe 20, the upper end ofwhich is; extended radiallythrough the head member 4 and has screw-threaded en gagement with a boss 21, formed on the top of said head member.- The inner end of the head member 3 is notched at diametrically opposite points, as indicated by the numeral 22, to permit the required telescopical movement of the head member 3 past theair pipe, 20 and also to hold said members agaiaarmary movement, with reparto normally pressed onto these valves 25 by the springs 16 and closed to prevent the dis charge of liquid therefrom. Screwed onto hubs, on the under side of the collars 24, are cages 26 in each of which is mounted a liquid controlled float valve 27.

The stem 28 of the valve 27 is extended axially therethrough and the upper end projects into the respective air pipe 20 and the lower end projects through the bottom of the cage. It is important to note that the bottoms of the cages 26 are conically recessed at 29 so that the lower circumferential edges of said cages are relatively sharp. On the bottom of each cage 26, is a guide 30 for directing the filling tubes 15 into the bottles. These guides 30, as shown, are

H made up of upwardly diverging wires.v the ends of which extend through the bottoms of the cages 26 and afl'ord rest lugs 31,- on which the floats 27 rest. The purpose of 7 thus supporting the float valves 27 is to hold the same above the bottoms of the cages 26 and permit the free passage of air and liquid into the cages at polnts surrounding the valve stem 28.

Screwed on to the upper ends of the air pipes 20, are cylindrical valve casings 32, having radial ports 33, which have communication with the air pipes 20 through the valve casings 32. Needle valves 34 are screwed into the upper ends of the casings 32 and arranged to close more or less of the ports 33 to regulate the escape of air from the bottles.

The apparatus is intended to be held in 1 both hands of the operator, the one hand grasplng the pump cylinder 5.

grasping the tube extension 2 and the other With the apparatus thus held, the same may be lowered to carry the filling tubes into two of the bottles to be filled and liftedto carry said filling tubes out of the filled bottles. By

- adjusting the members of the head 3-4 rat-us, the filling tubes 15 are laterally with respect to each other, the filling tubes 15 may be set in positions to enter bottles set at different distances apart. The sealing stoppers l8 mayalso be adjusted to vary the depth to which it is desired to have the, filling tubes 15 enter the bottles. I

In fillingbottl'e's with the improved appainserted into two of the empty bottles and the same sealed .by'the stoppers 18. These stoppers 18 also act as stops to limit the downward movement of the filling tubes 15 and by a downward pressure on' the head 34:, the springs 16 are compressed, allowing the pipes 20 to move axially through the filling tubes 15 to open the valve 25, as shown in Figs. 1 and 2. The liquid is discharged radially from the filling tubes 15, strikes the sides of the bottles and thus prevents foaming. As the bottles are filled with liquid, the displaced air passes upward through the openings in the bottoms of the cages 26, around the valves 27, into the air pipes 20 and escapes through the ports 33 to the atmosphere. hen the bottles are nearly filled with liquid, the float valves 27 are raised thereby and close the lower ends of the air pipes 20, thus preventing further displacement of the air from the bottles, .and hence, stopping the flow of liquid from the filling tubes 15. The pressure on the apparatus is thenreleased, allowing the springs 16 to seat the filling tubes 15 on the valves 25 andcutting off further escape of the liquid, when the ap paratus is shifted to the next pair of bottles to be filled.

By screwing the air pipes 20 into or out of the boss on the head member 4, the tension of the springs 16 may be adjusted. The escape of air through the ports 33 may be regulated by adjusting the needle valves 34. The position of the valves 3%, with respect to the ports 33, of course, depends on the force with which the liquid is delivered into the bottles.

In case only one bottle is to be filled at a time, the outer filling tube 15 may be turned into an inoperative position, as shown by broken lines in Fig. 1. This movement of the filling tube is accomplished by separating the members of the head sufiiciently to carry the notches 22 out of engagement with the air pipes 20 to allow the head memher a to be rotated on the head member 3. When the outer tube is in an upright position, the member 4 is then telescoped onto the member 3 to again carry the notches 22 into interlocking engagement with the air pipes 20.

While the apparatus shown has only two filling tubes 15, it is, of course, understood that any desired, number may be employed. As the action of each filling tube 15 is entirely independent of the other, the same will operate, even if the pressure is much harder over one of the filling tubes than the other to cause a wider opening movement of the respective valve 25 and hence,- a faster discharge of the liquid. By making the lower edges of the cages 26 relatively sharp, the liquid, in case any of the same flows down the sides of the cages, will not be sucked by the escaping air into' the pipes 20,

but will drip into the bottles.

The above described invention, while it is very simple, has, in actual usage, proven highly eilicient for the purpose had in view.

What I claim is 2- 1. A bottle filler having a liquid supply head comprising two telesco ically connected members, each having a lling tube, and means for locking the members of the head against rotary movement with respect to each other and in difierent axial adjustments to vary the distance between said tubes.

2. A bottle-filler having a liquid supply head comprising two telescopically connected members, each having a filling tube, and means for securing the members of the head in different axial adjustments to vary the distance between said tubes.

3. A bottle filler having a liquid supply Copies of this patent may be obtained for nected, each member having a filling tube,

a pump cylinder integrally formed with one of sald members, and a flexible liquid supply tube attached to the other of said memhere.

In testimony whereof I affix my signature in presence of two witnesses.
