FILLING DEVICE FOR BOTTLES- SPEGIFICATION forming part of Letters Patent No. 755,600, dated March 22, 1904.

Application filed April 1, 1903; Serial No. 150,583- (No model.)

To all whom it may concern.-

Be it known that I, CHARLEs A. CARLsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling Devices for Bottles, of which the following is a specification.

The object of this invention is to provide means by which bottles may be filled with carbonaceous liquidssuch as ginger-ale, pop, 860. -making the filling operation automatic by admitting the syrup and carbonized water to the bottle and venting the air therefrom by a single operation, and the apparatus is so constructed that the force necessary to operate the device is supplied by the pressure in the tank and the valve for admitting the syrup to the bottle operates the plunger for forcing the syrup through the valve, thereby making the operation automatic and certain, efiecting a great saving of time and labor, and making the flow of the liquid more certain and uniform than has hitherto been the case. The device is one that may be easily applied to any ordinary pressure-tank, the apparatus for producing the various steps aforesaid being'entirely exterior of the tank, thereby enabling the device to be fitted to existing tanks without the necessity for rearrangement or adaptation.

The invention consists of the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure l is a side elevation of the entire device in position to be secured to a pressure-tank; Fig. 2, a longitudinal sectional view taken through the piston-cylinder and end of the filling-valve; Fig. 3, a top or plan view of the valve; Fig. i, a side view of the tapered plug, showing the passages therein in dotted lines; Fig. 5, a top view of the plug; Figs. 6 and 7, cross-sectional views taken on line 6 7 of Fig. 3, showing the water-pasvalve, and Fig. 13 a longitudinal sectional view of the valve open.

The syrup enters the device through a pipe A, leading up to a syrup-containing tank (not shown) located high enough above the apparatus to insure a good head to facilitate the flow of syrup, and said pipe is screw-threaded, as shown, into a nipple'a, in which is located a check-valve a, provided on its face with ribs (6 and further provided with a seating-face a and a downwardly-projecting stud a for regulating the movement of the check-valve. The nipple is entered into a pipe B, provided on its upper face with a screw-threaded ring or collar B and terminating in a screw-threaded end 6, to which the valve proper is secured. Within the ring or collar is a cylinder C, provided with a cylinder-head c at its upper end, upon which are a stufling-box 0 and a nipple 0 through which pressure is admitted to the cylinder. Within the cylinder is apistonlD, provided with a piston-rod D, upwardly extending through the stufiing-box and between upright supports d, which latter are provided with a cross-head cZ, through which the pistonrod passes and above which is located a coilspring 03 secured in place by means of an adjustable collar (Z encircling the end of the piston-rod and longitudinally adjustable thereon.

The end of the syrup-pipe B enters a tubular boss 0, located on the front face of the shell I or casing E of the filling-valve E, and the casing is provided with a squared head 6' for the attachment thereto of a bottle-holder F of a suitable formation, and the casing is further provided with a contact-face e and a screwthreaded plug 6 adapted to screw up into the pressure-tank for attachment of the valve thereto.

Within the shell or casing is a tapered plug F, in which is a passage f, provided with a slotted mouth f ,which when the valve is open, as in Figs. 2 and 10, communicates with the passage in'the boss 6, but when the valve is closed, as in Fig. 11, is out of communication therewith by a very small margin, so that a slight turning of the valve will serve to bring the passages into communication withone another, enabling the syrup to pass through the shell or casing and into the plug. The syruppassage f enters a longitudinally-extending passage f 2 in the center of the plug, which latter terminates in an annular passage G, surrounding a transversely-extending circular opening or water-passageGr, which passes entirely through the plug, and when the valve is open, as shown in Fig. 13, is in communication with a central aperture or passage 9 in the plug of the valve-casing in direct communication with the interior of the carbonized water and pressure tank, into which the valve is inserted. The transverselyextending passage Gr is counterbored in two places 9 and into the former of which is screw-threaded a filling-tube H, which passes through afillingcap H, provided with a screw-threaded neck h, screw-threaded into the counterbore 9 as best shown in Fig. 13, which shows the valve open and the passages in communication with one another. Directly above and communicating there with the transversely-extending passage f is an air-equalization passage I, and when the valve is open, as shown in Fig. 13, the passage I communicates with a passage 7 in the screw-threaded plug, into which latter passage is inserted an air-equalization pipe 2', which extends up above the water in the tank and is adapted to establish communication between the tank and the bottle when the valve is open. As shown in Figs. 10 and 11, the passage I is not provided with a slotted mouth, as is the syrup-passagef, by reason of which the space to he traveled by the passage I in order to come into communication with its companion passage in the shell or casing is much greater than is the distance to be traveled by the passage f, so that as the valve is turned communication between the syrup-passages will be established before communication between the air-passages has been made. Near the end of the filling-tube in the wall thereof is an opening J, which communicates with the annular passage G, extending around the transversely-extending passage G, and the filling-tube is further provided with a longitudinal indentation j in its wall, leading down from the annular passage through the neck h and terminating at a point f in the wall of the filling-tube belowthe filling-cap and within the interior of a bottle when the same has been inserted into place within the filling-cap. It will thus be seen that the syrup first passes through the passages f, G, and J into the filling-tube before communication is established between the water-passages g and G, which communication is established at substantially the same time that communication with the interior of the bottle is complete through the air-passages f 1, f and I, which arrangement enables the bottle to be first filled with a predetermined amount of syrup and afterward filled with carbonized water under pressure at the same time that communication is established between the tank and hottle to enable the air within the latter to pass up and escape into the tank, allowing the water to flow down and fill the bottle.

The piston is operated by pressure from the tank which flows down through a pipe K, which enters a passage k in the screw-threaded plug, which passage, as shown in Fig. 8, is in communication with an angular passage K in the plug, having a slotted inlet-opening in and a similar outlet-opening in communication with a passage 71: in a nipple 10*, to which is attached a rubber hose or similar communication K which leads to the nipple c on the pressure-cylinder and enables the same to be operated by means of the pressure in the tank, and, as shown in Figs. 8 and 9, it takes but a slight movement of the valve to establish communication between the tank and the cylinder, forcing down the piston thereof and forcing. the syrup within the piston and syrup-pipe B through the valve and into the bottle. The movement of the valve causes the syrup-passages and the pressurepassages to be opened simultaneously, so that the syrup will be forced down into the bottle before air is discharged therefrom or water admitted thereinto. The check-valve prevents the backflow of the syrup, and the piston may be so regulated by means of the spring and adjustable collar that the amount of syrup admitted to the cylinder below the piston may be regulated to suit different requirements, thereby causing the amount of syrup forced into each bottle to be the same and insuring uniformity in the quality of the bottled goods.

In order to provide for the escape of back pressure from the cylinder after the syrup has been discharged therefrom, the end of the plug adjacent to the pressure-passages is provided on its exterior with a slot L, running to the end of the plug, as shown in Fig. 4, and communicating with an annular chamber L in a cap L which closes the end of the valve, in which is a vent-port L as shown in Figs. 12 and 13 of the drawings, and, as shown in Fig. 9, when the valve is closed the inner end of the slot L is in communication with the passage 70 and a rubber tube leading to the cylinder, so that as soon as a bottle has been filled and the valve drawn back to closed position communication will be established between the cylinder and the vent-opening, allowing pressure behind the piston to escape and permitting the syrup in the syrup-tank to flow down by gravity and force back the piston, again filling the cylinder preparatory to the insertion of another bottle into place to be filled.

Although the invention has been described with considerable particularity as to details, it is obvious that the latter might be modified and the form of valve and arrangement of piston in relation thereto considerably varied without departing from the spirit of invention. The device is one which makes the entire filling operation automatic after the insertion ofthe bottle onto the filling-tube and relieves the operator from the necessity of removing the bottle after the same has received the syrup preparatory to the admission of carbonized water thereto.
