PATENT OFFICE JAMES KANTOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE LIQUID CARBONIC COR- PORATION, OF QHICAGO, ILLINOIS FILLING MECHANISM Application filed. March 14, 1927. Serial No. 175,316.

My invention relates to improvements in,

filling mechanisms of the type which are adapted to dispose measured amounts of liquid, such as syrup, in bottles, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to providc'a filling mechanism in WlllClltllG capacity of the measuring means may be varied to the slightest fraction of an ounce.

A further object of my invention is to provi-de a device of the type described by means of which desired quantities of the liquid may be disposed in each bottle, irrespective of the temperature effect upon the liquid or the den sity of the liquid used.

A further object of my invention is to provide a device of the type described which may be readily substituted for the old type of measuring means.

A further object of my invention is to provide a devlice'of the type described which is simple in construction, durable and eflicient for the-purpose intended. I

Other objects and advantages will appear V in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims. r

My invention is illustrated in-the accompanyingdrawings, forming part of this application, in which :Figure- 1 is a side elevation of my device, portions thereof being shown in section,

Figure 2 isa plan view of myvdevice, and

Figure 3is a sectional View of a portion of my device.

In carry ng out my mvention, I provide a liquid tank '1 having one or more openings 2 in the bottom wall 3 thereof. Aguide or supporting rod 4 is slidably disposed in a bushing 5 which extends through the bottom 8 of the tank 1. A bell 6 for receiving the neck of a bottle, which is indicated at 7,-is

rigidly mounted upon the lower end of the guide rod 4- A compression spring 8 is disposed concentric with the guide rod 4 and bears at one end .upon the bell 6 and at the other end upon the bushing 5. A support 9 in the form of a triangular block is secured to the upper end of the guide rod 4 by means of a nut 10. A measuring cup which is composed of a cylindrical body portion 11 and a bottom portion 12 having its inner wall tapering downwardly toward the center thereof is disposed in the tank 1 in alignment with the opening 2.. The measuring cup is so constructed that the cylindrical body portion 11 may be moved with respect to the bottom por tion 12 and still prevent a liquid from passing from the cup between the body portion 11 and the bottom portion 12. The bottom portion 12 is provided with a groove 13 for receiving one end of a fork 14. The other end of the fork 14: is rigidly secured to a supporting rod 15 which extends upwardly through the support 9 and is rigidly secured thereto by a nut 16. In this manner, the bottom portion 12 is rigidly held against movement with respect to the support 9. I

A sleeve 17, rigidly secured at 18 to the body portion 11, is disposed concentric with is providedwith indicating lines 25 circumferentially disposed thereupon. A look nut '26ris disposed upon the reduced portion 23 for'holding the indicating cylinder 24% in any adjusted position.

a The collar 22 is -held against longitudinal displacement by a forked retaining plate 27,

the forked 'end28 of which is receivable in an annular groove 29 ofthe collar. "The forked retainingplate 27 is rigidly held bev tween the support 9 and the nut 10. I An indicating line or groove 30 is disposed in the forked retainingmember 27, see Figure 2. An indicating wheel-31 is disposed concentric with the collar 22 and is, provided with indicating lines 32 which are equally spaced thereupon and extend inwardly from the peripheral edge thereof, An adjusting nut 33 is provided with an internally threaded portion 3 1 which is adapted to receive external threads 35 upon the collar 22. A set. screw 36 extends through the adjusting nut 33 and is in engagement with the indicating wheel 31. The set screw 36 acts as akey to prevent rotation of thenut 33, and locks the indicating wheel 31 against rotation with respect to the adjusting nut 33.

A liquid valve tube 37 is rigidly secured to the tank 1 and extends upwardly through the opening 2 in the bottom 3 to a point above the level of a liquid 38. This liquid is kept at the predetermined level by means not shown. The lower portion of the liquid valve tube 37 extends downwardly through the hell 6 and is adapted to enter the bottle 7. A drip check 39 is adjustably secured to the support 9 by the nut 16 and is positioned in alignment with the liquid valve tube 37.

The check 39 may be moved into and out of alignment with the tube 37 for a purpose hereinafter described.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. As stated heretofore the liquid 38 maintains approximately the level shown in Figure 1, irrespective of the speed at which the liquid passes from the tank.

Let us assume that the operator wishes to place four ounces of the liquid 38 into the bottle 7. The measuring cup, as shown in Figures 1 and 2, is set to receive just four ounces of the liquid. As the bottle 7 is moved up .wardly by means not shown the bottle engages with the hell 6, thus raising the bell, the guide rod 4, the support 9, and the measuring cup upwardly to a point where the up measuring cup; When the measuring cup has reached its uppermost position, the drip check 39 will have been raised from the liquid valve tube 37 and the upper extremity of the liquid valve tube will be adjacent the lower portion of the tapering surface of the bottom portion 12. This allows the liquid which has been retained in the measuring cup to flow downwardly through the tube 37 into the bottle 7. The tapering surface of the bottom This time remains the same, irrespective of the surrounding temperature and the specific gravity of the syrup. As for instance, a liquid, such as syrup, Wlll flow at a slower rate of speed during a relatively low surrounding temperature than when the surrounding temperature is relatively high. Some syrups or liquids, owing to their density, require more time to flow from the measuring cup into the bottle than do others. To allow for the slowness of the flow of the liquid during a relatively low temperature, or with the use of a relatively heavy syrup, the body portion 11 may be moved upwardly with respect to the bottom portion 12 by rotating the adjusting nut 33 in a clockwise direction, looking from the top of the ad justing nut. With this adjustment, the measuring cup may be tested to allow the desired four ounces of liquid to pass intothe bottle in the limited time. After this ad justment has been made, by removing the set screw 36, the indicating wheel 31 may be reset to register correctly. By again inserts ing the set screw in place, the indicating wheel 31 may be held in adjusted position. In resetting the indicating wheel, it is obvi ous that the indicating line adjacent the marking O should be in alignment with theindicating line or groove 30.

As the bottle 7 moves downwardly, the measuring cup is also moved downwardly by" the force of the compression spring 8, and" the drip check 39 engages with the upper end of the liquid valve tube37 for preventing any'liquid which should remain in the tube from passing therefrom until another bottle is brought into alignment withthe tube. The drip check 39 is essential when the device is used in a low surrounding temperature or with a heavy liquid for holdingall the liquid over four ounces which is received in the measuring cup. If the check 39 is moved out. of alignment with the tube 37,the liquid in the tube would continue to flowtherefrom;

Let .usassume that the operator wishes to place three ounces of liquid within the bottle. By rotating. the adjusting nut 33. in a counter-clockwise direction, looking from" the top of the nut, the sleeve 17 vis moved downwardly upon the supporting --rod 15 thus movingthe body portion 11 downwardly with respect to the bottom portion 12 and decreasing the capacity of the measuring cup to three ounces. The purpose ofthe gradu ations 25 upon the cylinderQt is to indicate to the operator that when the line adjacent the marking ,3 oz. has been moved downward- 1y into alignment with the upper extremityl of the collar 22 and theindicating line adj acent the marking() upon the indicating wheel has been brought into alignment with the indieating line 30, the measuring cup will hold i just three ounces of the liquid38. The indicating lines upon the wheel 31 each represent g of an ounce. One-half a revolution of the indicating wheel 31 and adjusting nut 33 7 increases or decreases the capacity of the measuring cup of an ounce, and one whole revolution of the indicating wheel and adjusting nut increases or decreases the capacity of the measuring cup of an ounce. In this manner, the body portion 11 may be moved with respect to the bottom portion 12 so that the measuring cup will receive any desired amount of the liquid 38. It is obvious that with this adjusting means the capacity of the measuring cup may be varied at will from a fraction of an ounce and more. After the body portion 11 has been moved to the desired position with respect to the bottom portion 12, the indicating wheel 31 may be locked against rotationby a screw which is carried by the support 9.
