FILLING MACHINE.

To all whom it may comem:

Be it known that I, EDWARD H. WEATHER- HEAD, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga,

and State of Ohio, have invented a new and useful Improvement in Filling Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements relating, as indicated, to a filling machine, have more particular regard to a device for filling botthis with syrup or other liquid prior to the introduction into the bottles of the greater ortion of the liquid with which they are to e filled. Thus in the filling of bottles with ginger ale, root beer or other soft drinks, it is customary to first supply one or more ounces of concentrated extract in one machine, and then to transfer the bottles to another machine, in which they arecompletely filled with plain or charged water to make the desired beverage. lhe present invention consists of a machine for thus preliminarily filling the bottles with one or more ounces of syrup. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly point- 7 ed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Figure 1 is a side elevation of my imroved machine shown partially in section; igure 2 is an enlarged sectionalview of the syrup compartment and operating mechanism for filling, shown intheir normal positions; Figure?) is a section on line 3-3 in Figure 2; Figure 4'is a similar section, but: with the valve in a different position; Fig-.

ure 5 is a side elevation of the valve; Figure .6 is a section taken on the same plane as Figure 2, but showing the valve in the position shown in Figure'4; Figure 7 is a section through the valve taken on the line 7-7 in Figure2; Figure 8 is a section of the valve on the line 8-.8 in Figure 6; Figure 9 is a section of the valve on the line'99 in Figure 6 and Figures 10 and 11 are other sections of the valve showingthe same in different operative positions, these sections bein taken on the line 9-9 in Figure 6.

eferring now to Figure 1; the machine consists of a base 1 upon which are mounted uprights 2, constituting a framework. Centrally mounted in such base is a vertically disposed support 3, upon which there is rotatably mounted a series of vertically movable supports'or bottle holders 4. These bottle holders are movable vertically by means of a piston 5 operating in a cylinder 6, which is connected at both its upper and lower ends with a source of fluid pressure supply by means of

conduits

7 and 8 respectively. The bottle holders or lifts rest normally upon a sup-porting table suitably mounted upon the central support 3. It will be seen that the general construction of the machine is similar to that of the well-known rowhich is connected by means of

various valves

14, 15 and 16 tochambers or reservoirs containing various kinds of liquids such as syru Extending through the conduit 11 is a uid pressure supply conduit 17, which is connected at,its upper end to a suitable source of fluid pressure supply and which connects at its lower end to a lateral conduit 18 which is branched and leads to either end of cylinder 6. The lower end of the cylinder 6, that is the space below the piston in the same, is always connected with conduit 8, but the upperpart of this cylinder is normally disconnected from the conduit.

18 by means of a valve 20 rotatably mounted in the filling arm 9. p

The syrup supply conduit 11 connectsby means of a passage .21 with the upper part of a syrup dispensing chamber or cylinder 22, which is mounted in the -filling arm 9 directly above the bell mouth 10. The upper part of this syrup chamber 22 is connected to the lower part. by means'of the passage 23, which may be opened or closed as desired by means of the valve 20, as is shown in Figures 3 and 4. Operating in the cylinder 22 is a piston 25, which is connected to a second piston 26 operating in a second and aligned cylinder 27, which in turn is connected direct to a larger piston-28 operating in a third cylinder 29. This lastnamed cylinder 29 is connected at its upper end to the air supply conduit 17 by means of a pipe 30. The upper position of the piston 28, and henceof the

pistons

26 and 25, which are connected thereto, is limited by means of a stop in the form of an adjustable rod 31. This rod 31 extends beyond the cylinder 29 and such extending portion is marked off as shown in Figure 2 by lines which represent ounces of syrup admitted to the dispensing chamber 25. In this way an operator can accurately control the amount of syrup supplied to each bottle of the dispensing chamber.

, The cylinder 29 is at all times connected by means of a passage 90 with the air supply conduit 18. By this system of passages a differential action is secured in the cylinder 29 as follows:

jVhen air is admitted above the piston 28 the piston is forced down, since the air pressure is acting down on the upper surfaces of

pistons

26 and 28, and up only on the bottom surface of piston 28. When the air pressure above the piston 28 is discharged, then the pressure between

pistons

26 and 28 will exert a differential. action or 7 shown in Figures 1 and 2. Assuming that a bottle is in position on the holder 4 when the machine has rotated through a certain distance, an arm 35, attached to the valve 20, is operated by means of a'member 36. Before this operation the valve 20 is in the position shown in Figures 2 and 3, and the new position of the valve is shown in Figures 4 and 6. The valve opening device 36 is shown at the right of Fig. 1, which comprises a frame 50 having a pivotal lever 51' and an arm 52 attached thereto, the end 53 of which normally projects into the path of a bottle as it reaches a position opposite this opening device. The rod 52 is held in this position by means of a coiled spring 54 pressing a plunger 55 out of engagement with the cam or valve operating arm 35. A bottle on the stirrup however acts to press the rod 52 outwardly and force the plunger 55 inwardly into the path of the arm 35. Means, illustrated at the left in Fig. 1, as an adjustable cam lug 56 projecting into the path of the arm 35, when the valve 20 is open, 18 employed to actuate said arm to return the valve to'its normally closed position.

After the valve 20 has been operated and' moved into position as shown in Figures 4 and 6, the various parts of the machine are operated to supply syrup in a measured amount to the bottle. When a valve is moved in the manner just described, the piston 5 is ,raised in the cylinder 6, since the air pressure in the latter is then allowed to escape through the passage 7 into an intermediate connection 40 in the valve 20 to the atmosphere. By thus exhausting the pressure above the piston in the cylinder 6 the air pressure below the same is enabled to lift the piston and with it the bottle holder 4 forcing with it a bottle into the bell mouth 10. This exhaust of air from cylinder 6 is made slightly in advance of the admittance of air to the cylinder 29, as best shown in Figs. 8 and 9 in which the exhaust passage 40 is provided with a lateral offset 100 which will allow the air above the piston 5 to exhaust slightly ahead of the admission of air to cylinder 29 as the valve is rotated in a counter clockwise direction. These two actions follow so rapidly that the operation is almost simultaneous but the difference in time is just sufficient to allow the bottle to actually reach its position in the bell mouth before the syrup begins to flow into the bottle.

When the bottle is so positioned in the filling spout, air pressure is admitted to the top of the cylinder 29 through the

passages

30, 43, 18, 17 and a passage 41 formed in the valve. This air pressure on the top of the piston 28 forces down this piston and also forces down the piston 25 which acts upon the syrup in the chamber 22 to discharge the same through a passage 81 formed in the valve and connecting with the spout.

When the bottle is thus filled, the machine has rotated to such a point that a. second cam operates against the arm or trip 35 to return the same to its normal position, thus moving the valve back to the position shown in Figures 1, 2 and 3. The filling bell mouth 10 is formed with an .undercut recess 61, thus providing a shoulder against which is placed a collar 62 disposed slidably about the filling tube and normally maintained in contact with such shoulder by means of a spring 63. When a bottle is positioned in the spout it forces up the collar 62 and compresses the spring 63. The compression of the spring is suflicient to overcome the sticking of the bottle in the spout due largely to the syrup, when the bottle lift starts to fall. Upon this return movement of the valve the escape of air from the upper part of the cylinder is cut off by the valve and air pressure being admitted to the cylinder through a passage 43 connecting with an intermediate passage 44 in the valve. The pressure is balanced on both sides of the piston 5,

rod attached to the lower side of the piston 5 which causes a greater pressure against the upper side, this excess pressure forcing the piston down.

At the same time the passage 30 leading from'the top of the cylinder 29 is connected to the atmosphere through a passage 45 in the valve, thus permitting the pressure on the under side of the piston 28 to raise this piston and also the piston 25 in the syrup chamber. Such movement of the piston 25 will draw syrup through the: passage 23 and through the valve (see Figure 3) into the syrup chamber 22. On the piston 25 there is formed an annular rib 91 which seats in.the lowest position ofthe piston upon a washer 92 which is placed upon the bottom of the cylinder 22, this rib acting as a valve to prevent any leakageof syrup past the piston when the piston is in its lowermost or filling position. By using this rib and 'washer, it is unnecessary to provide any packing for the piston itself.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, pro

vided the means stated by-any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a syruping machine, the combination of a plurality of radially arran ed horizontally disposed rotatable filling arms, each arm being a single member and being provided with separate passages for syrup and syrup discharging fluid pressure, a centrally disposed syrup supply conduit connecting with such syrup supply passages in said arms, a fluid pressure supply conduit disposed centrally within said syrup supply conduit and connecting with such fluid pressure passages in said arms, a plurality of syrup supply reservoirs connected to said syrup supply conduit, and means for effectlng disconnection of each of said syrup supply reservoirs from said syrup supply conduit.

2. In a syruping machine, the combination of a plurality of radially arranged, horizontally disposed rotatable filling arms, each arm being a single member and being provided with separate passages for syrup and syrup discharging fluid pressure, and having mechanical means operable by fluid pressure to discharge syrup, a centrally disposed syrup conduit connecting with such syrup supp y assages in said arms, a fluid pressure supp y conduit diposed centrally within said syrup supply conduit and connecting with such fluid pressure passages in said arms to operate said mechanical means, a source of syrup supply and means for connecting the same with said syrup supply conduit. K

3. In a measuring and discharging device, the combination of a liquid cylinder having closed ends and capable of connection to a source of liquid, a source of liquid supply,

mechanically-operated valve means adapted to connect said cylinder to said supply, a piston in said cylinder and a passage connecting the two ends thereof whereby liquid may first be drawn into one end and then transferred to the other and then discharged therefrom, said piston and the walls of said cylinder being thereby immersed in such liquid at all times.
