MEASURING BOTTLE-FILLING MACHINE.

Specification of Letters Patent.

Patented N ov. 23, 1920.

Application filed July 12, 1919. Serial No. 310,406.

To all whom it may concern:

Be it known'that I, ARTHUR I. RIssER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and' useful Improvement in Measuring Bottle- Filling Machines, of whichthe fol owing is a specification.

This .invention is a machine for auto matically filling one or more bottles at a time with a definite lpredetermined measured quantity of liquid.

The object of the invention is to provide such a machine in which the quantity of liq.

uid delivered to the bottle or bottles is accura-tely measured, and to provide valve mechanism'by which, as such measured liquid is delivered to a bottle, the initial supply in the machine is automatically renewed.

The invention consists in mechanism for carrying out the foregoing objects which can .be easily and comparatively cheaply made,- which is satisfactory in operation, and not readilyliable to get out of order. More particularly the invention consists in the features and details in construction hereafter more fully set forth in the specification and claims.

Referring to the drawings, in which the same numerals represent like parts throughr out the several views:-

Figure 1 is an end view, partially in section, showing mechanism illustrating this invention in its preferred form.

Fig. 2 is a transverse view partially in' section on the line 2 2 of Fig.' 1.

Fig. 3 is a 4plan view of the filling mechanism taken on the line 3 3 of Fig. 1.

Figs. 4 and 5 are changed position views of the mechanism shown in the upper half of Fig. 2. l

The partlcular machine of the drawings i has a capacity for filling si; bottles at once but it may be built for one or any number more.

The bottles 10 to be filled, are placed upon A and back of the frame 14 are two parallel shafts 16 and -18 provided respectively, near their centers, with upwardly extending lever arms 20 and 22,conn'ected together by a link 24. Shaft 16 carries an operating lever 26, terminating in a handle 28 adapted to be grasped by the operator. It also carries a counterweight 3() so positioned and ,arranged as to normally hold all the parts of the mechanism in thev position of Figs. 1 and'2. v

On each end of shaft 18 is, as shown in the drawings, a downwardly inclined lever 32 pivotally connected to a vertical connecting rod 34 whose upper end is pivota-lly attached to a crosshead 36, rigidly attached to and carried by vertical plunger rods 38 slidable in suitable guides 40 and 42 attached to the table frame 12-14.

Rising from the table frame and rigidly l 'secured in the supports 4() and 42, just ref ferred to, are apair of stationary rods 44 supporting, at their tops, a normally sta-4 Y tlonary fixed cross bar 46. Adjustment of this cross bar vertically is (provided however, through the collars 48 placed below the bar on the rods 44 and suitably detachably connected to the rods, as for instance, by the set screws 50.

Normally, permanently secured to the cross bar 46 are two depending rods 52 f* carrying, at their lower ends, a displacing block 54. These rods 52 are, however, selec'- tively adjustable in height with reference to the cross bar 46 through the use ofv nuts 56 provided for thel purpose and usable in the obvious manner.`

Displacing block 54 is inclosed within a liquid tank 60 rigidly attached to the vertical rods 44 by any suitable means, as for instance, that shown at 62. The cover 64 of tank 60 is perforated for the reception of thev p rods 52, heretofore described, so that the tank as a whole may be reciprocated with reference to the displacing block 54 and said rods 52. Onthe bottom of tank 6() and inside it, are arranged a plurality of measuring cu s 65 one for each bottle 10 to be filled. ach such cup 65 terminates at its bottom in a tubular portion 66 contracted at its bottom into a discharge nozzle 68 adapted to deliver liquid to the adjacent bottle. Each measuring cup 65 is detachably secured in the bottom of the tank 60 by being screw-threaded from above through the bottom and finally fastened by a lock nut 70. The measuring cups are so placed with reference to each other and to the walls of the tank 60 that there is space between them for liquid 72 to be measured. Correspondingly, the displacing block 54 is provided with recesses 74 adapted to receive the cups 65 when the parts are moved to the position of Fig. 4 and with corresponding adjacent solid portions 76 which, in the position of Fig. 4, enter the liquid 72 without interference or clash with the cu s 65.

ach measuring cup 65 is provided-with a vertical valve rod 78 terminating at its lower end in a valve member 80 fitting into passage 68, heretofore described. Each one of these valve rods 78 slides freely through a suitable opening in tank cover 64 and also through bar 46 and is adjustably positioned with reference to this bar by an adjusting nut 82 screw-threaded on ther upper end of the rod. The rod is so adjusted that when the parts are in the positions of Figs. 1 and 2, bar 46 will hold each rod 78 with its end 80 out of engagement with nozzle 68 and permit liquid in the adjacent measuring cup 65 to flow out of nozzle passage 68, while when the parts move slightly from that position toward and to the position in Fig. 4 the rod will, by gravity, hold passage 68 closed, as shown in Figs. 4 and 5.

Extending across the machine between the nozzles 66--68 and the tops of the bottles 10 is a bar 86 slidably mounted on rods 38 between the collars 88 and 90 provided for the purpose and normally pressed downward by the springs 92. This bar 86 is perforated above each bottle 10 to receive a perforated bottle centering rubber cap 94 fittable at its lower end over the top of the bottle l0 to insure accurate discharge of liquid passing from nozzle 68 into the bottle. This member 94 is provided in each case to insure accurate positioning of the bottle with reference to the nozzle irrespective of irregularities in the size and co'nstruction of different bottles placed'under the nozzles ofthe machine.

The cover 64 of the tank 60 is provided with an intake or supply valve mechanism housing 96 to which liquid material to be used in filling bottles is delivered from a source of supply, not shown, through a pipe 98. The'exit end ofth'is pipe 98 entering this housing 96 is closable by a valve 100 on the upper end ofra rod 102 terminating in a fioat 104 in tank 60. The parts, just described, are so positioned that when the rest of the mechanism is in the position of Figs. 1, 2, and 4, the valve 100 is closed and no liquid is supplied through pipe 98 into tank 60 but, what when the parts are in the position of Fig. 5 and the intermediate positions, valve 100 is more or less open and liquid is admitted to tank 60.

Starting with the machine in the position of Figs. 1 and 2, with the bottles 10 shown just filled from the cups 65 which are nowA empty, the passages 68 being still open, with liquid 72 inthe tank ready for filling bottles. The operator takes holdl of handle 28 and moves it upward, thus moving rods 38 and, consequently, tank 60 upward. As this movement begins, blocks 88 'move up into engagement with the ends 110 of bar ary, the movement described in effect immerses the block in the liquid 72, as shown in Fig. 4, thus raising the level of liquid 72 sufficiently so that it ru-ns over into and fills cups 65. This movement has raised valve rod 78, as shown in Fig. 4, but they still hold valves seated, as shown in Fig. 4.

lVhen sufficient time has elapsed for all the cups 65 to fill, the operator starts handle 28 back toward initial position. In so doing the parts first reach the position of Fig. 5, in which the liquid 72 is below the upper edges of the measuring cups 65, thus causing float 104 and attached parts to move down and open valves 100, thus admitting new liquid to the tank. As the mechanical mechanism continues from the position of Fig. 5 to normal position, this valve 100 re-y mains open until such time as liquid delivered to pipe 98 refills tank 60 to the condition shown in Figs. 1 and 2, whereupon the liquid in the tank raises float 104 and closes valve 100. As the parts move from the position of Fig. 5 to that of Fig. 1, and just as they reach the latter position, the nuts 82 on rods 78 catch upon the bar 46 so that further downward movement of the tank 60 results in opening the valves 68 and allowing the measured quantity of liquid -viz., the entire contents of the respective cups 65 to fiow into the newly placed respective bottles.

It will be seen that the springs 92 allow for the use of different sizes of bottles in the "'machine and that, irrespective of the size of bottle used, the amount of liquid delivered into the bottles may be varied by selectively changing the size and capacity of the particular measuring cups used and also by determining, in advance, the exact distance which the displacing block 54 is submerged in the liquid.
