A CORPORATION OF ILLINOIS.

FILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 788,681, dated May 2, 1905.

Application filed July 25, 1904- Serial No. 218,013.

To all wtont it may concern:

Be it known that I, FRANK C. H. ST1-msnenenn, a citizen of the United States, residing at Chicago, in the county ot' Cook and State ot' Illinois, have invented new and useful lmprovements in Fillingh/lachines, ot' which the following' is a specilication.

'.lhe object oi' this invention is to automatical] y center a receptacle to be lilled in proper relation to the filling-tube ot' the machine, so that the filling-tube will be sure to enter the bottle without encountering' the edge of its mouth.

For convenience in explaining the invention I have shown it in the accompanying' drawings in .connection with the means Afor raising' the bottle of the kind disclosed in my application Serial No. 185,112 and with a lilling-valve mechanism ot the kind disclosed in my application Serial No. 185,161, both iiled December le, 1903; but it will be understood that the invention can be adapted for other i'illing-machines in which the filling-tube enters the bottle.

In the drawings, Figure 1 is a sectional view showing the invention with as much of the general structure ot' the machine as is necessary to understand the operation ot' the invention. Fig. 2 is an enlarged sectional view oi' the lilling-valve and bottle-guide. Fig. 3 is an elevation ot' the parts shown in Fig. 2 on a smaller scale.

Referring to the drawings, 10 is a liquid,

tank or receptacle to which the filling-valve mechanism is connected, and 11 is a bottle supported on a rest 12, which is carried by the vertically-movable stem 13. The bottle is raised to operate the valve by a cam 14, which operates a crank-lever 15, connected by one or more linkslG to the stem 13.

The filling-valve mechanism comprises a body 17, which has a central bore 17', into the lower end of which the iilling-tube 18 is secured. Rods 19 carry the liquid-valve 20, and a head 21, slidable on the lilling-tube, is provided withV openings 19 to receive these rods. Springs 22 on the rods normally hold the liquid-valve against its seat at the upper end ol" the bore 17. The head 21 is provided with an enlarged bore 23, which communicates by a passage 23 with a valve-chamber 24, and an air-tube 25 projects into this chamber and carries a check-valve 26, which will open to permit air to 'How into the bottle, while an opening' 27 in the air-tube (controlled by the set-screw 28) permits air to flow from the bottle through the tube into the tank. The upper end oil the air-tube projects through the body 17 and carries a valve 29 in the housing 3() within the tank, a tube 31 beingconnected to the housing' and extending' above the level oi? the liquid in the tank.

The present invention consists oi' a guide slid ably arranged on the filling-tube to center the bottle automatically, so that the tube will enter the bottle properly without encountering the edge of its mouth, which would be apt to result in breaking the bottle and injuring'themechanism. Thisguide32isshown in its lowest position on the filling-tube in Fig'. 1 and in its elevated position in Fig. 2, and it is iiared or bell-shaped at its lower end 33 and provided with a socket 34 to receive the mouth ol the bottle, which is adapted to engage the rubber seat 35. The upper end ot' the guide is reduced in size or contracted to enter a socket 36 in the lower end of the head 21,`and the guide is provided with a bore 37 to receive the filling-tube and also with one or more passages 39 to permit air to pass 'from the bottle into the passage formed by the bore 23 oi the head. A rubber gasket 21 may be located in the socket 36. The head is prevented from slipping' oil' of the iilling-tube at its lower end by providing a stop of suitable character, as by flaring or expanding the tube, as shown at 38.

With a centering-head of this character the operator may place the bottle rapidly on the rest without being particular to observe that the mouth of the bottle is exactly alined with the iillingtube, because the bottle will on its upward movement lirst engage the guide, which oilers suiiicient resistance by reason of its weight to the bottle to cause it to move into proper position to receive the iillingtube. The inner wall of the socket 3a of the guide is smooth, and the outer edge of the mouth of the bottle will slide easily and freely thereon into position. On the continued upward movement of the bottle the guide is finally moved into the socket 36 of the head and the latter moved upward to first unseat the air-valve 29 and then unseat the liquidvalve 20. Vhile the bottle is being lowered the guide will return to its position at the lower end of the filling-tube by gravity.

Vithout limiting myselt1 to the exact construction and arrangement of parts herein shown and described, what I claim, and desire t0 secure by Letters Patent` isl. In a lilium-machine, the combination of a liquid-tank, a liquid-valve in the tank, a filling-tube, a head slidable on the iilling-tube and connected to said valve, a valved air connection between the tank and the head, and a slidable guide normally suspended on the lilling-tube at the lower end thereof1 to adjust the mouth of the bottle to receive the tube, said guide being provided with an air-passage to form a communication between the air connection in the head and the bottle.

2. In a lling-machine, the combination of a liquid-tank, a liquid-valve, a filling-tube, a head slidable on-the filling-tube and connected to said valve, a valved air connection between the tank and the head, and a slidable guide normally suspended on the illing-tube at its lower end and provided with an air-passage to form a communication between the air connection in the head and the bottle, said guide having' its upper end contracted and said head being provided with a socket at its lower end to receive the contracted end of the guide.
