This invention relates to a can filling machine, and has particular reference to can filling machinery which is capable of operating at high speed, and which deposits discrete solid material and liquid in each can as it passes under the influence of measuring and depositing mechanism.

The machine of this invention is an improvement on applicants Patent No. 1,533,536, granted April 14', 1925.

In can filling machinery, such as that disclosed in the above patent, and where both granular or discrete solid material is to be deposited in each can along with liquid, such as 15 brine, it has been found that in order that the brine may find its way into all the voids between the spherical or ovate discrete solids, and finally assume a height above the solids, that the speed of the machine must be curtailed, or the machine must be made larger so as to have more measuring pockets and directing funnels, so that the can will remain under the same for a greater length of time.

It has also been found that in machines of 5 the character shown in the above mentioned patent, and where the adjustment for the telescopic cups is on the upper turret, which is removed for cleaning the machine, that the adjustment is oftentimes lost, during the washing a0 process, so that upon the replacement of the upper turret, it is necessary to again adjust the machine for the grade of solids to be canned. It also follows that adjustments must be made for every different grade of solids being filled in the cans and when this adjustment has once been obtained and lost, by adjustment for a different grade, no means is provided for again setting the machine for the former grade, except the mere out and try expedient.

40 One of the objects of the present invention is to provide in a high speed camming machine, means for uniformly filling the cans with discrete solids and liquid surrounding and covering said solids.

Another object of the invention is to provide a machine wherein the liquids and solids may each be measured to any predetermined quantities, and each regulation cannot be disturbed by removing turret parts for cleansing the machine.

A still further object of the invention is to provide a can filling machine in which means are provided for indicating the capacities of the measuring cups, so that when once adjusted for grade, the machine may be quickly readjusted for other grades without experimenting,

A still further object of the invention is to provide in a can filling machine, a liquid supply which is operative only during the operation of the can filling machine.

According to the invention, the can filling machine has means for feeding cans into operative position for filling, means for supplying a measured quantity of liquid to each can during its travel through said feeding means, a pair of measuring devices each comprising an upper and lower turretproviding telescopic measuring cups, one of said devices having means for supplying discrete solid material to its cups, and the other having means for supplying liquid to its cups, a distributing member having funnels each adapted to successively receive the contents of a solid material cup and a liquid cup, and to direct same into a can to be filled; each of said lower turrets being rotated by a hollow shaft; each upper turret having a shaft secured thereto and extending through said hollow shaft; said shafts each provided with means for raising and lowering means, whereby the relationship between the turrets is adjusted to alter the capacities of the cups, and separate means each operated by one of said lastnamed means for indicating the cup capacity. The last-named means is a dial having a pointer operated through the means which operates the non-rotating shaft. The liquid supply is provided with a valve therein operated by means of a governor which in turn is operated by the mechanism which operates the turrets in order to open the said supply, and which said governor closes said supply when the machine is at rest.

Figure 11 is a vertical sectional view of the machine similar to Figure 1 except that the turn operating shafts are split.

The can filling machine shown in Figures 1 and 2 is designed for belt driving, the belt extending over the pulley I8 on the main shaft I1. While a pulley has been shown it will, of course, be understood that the machine may be direct motor driven or may be motor driven through a chain of gears, so as to impart the desired speed to the can filling devices. The main shaft I1 has a bearing I8 mounted on a bed plate I9, and its outer end is provided with a hand wheel 2I for operating the machine manually, when desired. The main shaft I1 has clutch mechanism 22, and a shipper handle 23 for operating the said clutch so that motion is imparted to the operative parts through the operation of the shipper handle engaging the clutch located in the intermediate position in the main shaft I1. This main shaft I1 has a bevel gear 24 on its inner end which meshes with a bevel ring gear 28 mounted on the hollow shaft 21. -In the design shown, the machine is provided with a table 28 which has standards 28 extending to the floor, although the machine may have a cylindrical drum type base with the table at the upper end of the same.

Cans are dropped into the depository 3i formed by the angle plates 32 and 33, and the lowermost one is taken by the feed screw 34 operated from the main shaft I1, and fed in an upright position to the star wheel 38 mounted on the hollow shaft 21. This star wheel 38 has a donwardly depending sleeve 31 terminating in a gear 38, which said gear meshes with a gear 39 operatively mounted on the star wheel 4i, which in combination with the rail 42 discharges the cans from the star wheel 38 after the same have been filled with discrete solid and liquid materials. The can feeding mechanism shown herein is described in detail in applicants Patent No. 1,475,675, granted November 27, 1923. Located above the tops of the cans A, which rest with their bottoms on the table 28, is an external ring gear 43 provided with collared apertures 44, which apertures are aligned with bottoms of the funnels 48 while the said ring gear is secured on the depending sleeve 41 of the funnel casting 45 by means of a set screw 48. The sleeve 41 is in turn secured to the hollow shaft 21 by the set screw 49. This gear 43 meshes with a pinion I84 on the shaft I88, while an idle gear I83 meshes with the gear I84 and with the gear I82 (see Figure 4) on the auxiliary briner shaft I11.

This funnel casting 45 has a flanged rim 5i operating on the ledge 52 of supporting frame 53, and this supporting frame has a partition or plate 84 extending entirely over the same, and closing the upper ends of the funnels 48. This plate 84 is shown in Figure 2, and it is provided with a discharge opening 58 which is located with respect to timing in exactly the same position as the discharge opening 82 in my United States Patent No. 1,533,536, first above referred to. The supporting frame 53 and plate 54 are stationary, while the funnel casting 45 and ring gear member 43, by reason of their connection with the hollow shaft 21, are rotatable. Mounted on the upper end'of the hollow shaft 21 is a collar 51, and this collar has keys 58 providing rotation for a lower turret member 59, which has its bottom end resting on the plate 54. This lower turret has upstanding circular collars 8i adapted to receive depending collars 82 on the upper turret member 83. The upper turret has a recess 84 in the hub 88 of same into which the end 81 of the shaft 88 is secured by means of a key 89. The hub 88 has a reduced upper end H on which is mounted a pinion 12. This pinion meshes with a pinion 13 which, in turn, meshes with the internal gear 14 on the hopper mounting 18, so as to impart rotation to the hopper 11. The hopper 11 extends at one side of the shaft 88, and the telescopic cups formed by the flanges 8i and 82 are closed by a cover 18.

The shaft 88 extends through the hollow shaft 21 and emerges from the bottom thereof, while said hollow shaft has a bearing 82 and a thrust collar 83 on the end thereof, and secured thereto by means of the set screw 84. From this description, it will be seen that the shaft 68 is rotatable with the turrets 59 and 83. The funnel casting 45 is substantially the same as the funnel casting 48 shown in Figures 3, 5 and 13 to 16 of applicants Patent No. 1,533,536, granted April 14, 1925, and its utility in combination with the telescopic cups of the turret members 59 and 63, and the pockets 88 of the turret members 81 and 88, is explained in detail in that patent, particularly as to the timing of the deposits of discrete solid material from the cups of the former members and liquid from the cups of the latter members into the pockets of the casting 45. The principle there explained and described in detail is exactly the same as the principle of the mechanism of this machine insofar as these parts are concerned, and it will suffice to say that discrete solid material is deposited into the funnels 48 from the cups of the members 59 and 83 prior to the deposit of liquid material into the pockets 89 from the cups of the members 81 and 88. The supporting frame 53 has an oblique platform 9| providing a support for a turret plate 92 located in the bottom of a liquid tank 93. The table 28 has an oblique bearing 94 to accommodate a hollow shaft 95 which extends up through the platform 9I and the bottom of the turret plate 92. This turret member 81 has flanges forming cups 98, the capacity of which cups is regulated by the plugs 81 on the turret member 88. This member is in the form of a plate and its hub 98 is secured to shaft 99 by means of a set screw IN. The upper end of the hollow shaft 95 has a driving disk I82 secured thereto by means of a key I83. This disk has depending arms I84 which engage lugs I88 of the lower turret member 81, while the upper turret member has depending pins I81 which are adapted to pass through holes I88 in the driving disk I82, so that upon the rotation of the hollow shaft 95, the lower turret member and upper turret member will rotate in unison, while the upper turret member is retained in position by its own weight, and may be freely removed from its engagement with the lower turret member, and

with the driving disk I82, so that the cups 98 and iii) plugs 91 may be readily cleaned when the machine is shut down, or when the machine is being changed over from one material to another. The hollow shaft 95 has a bevel gear I99'fastened to its lower end by means of a set screw I I9, and this gear meshes with a bevel gear III secured on the hollow shaft 21, so that the solid material turrets 59 and 63 and the liquid material turrets 31 and 88 are geared together and operate one with the other. The hollow shaft 95 has the shaft 99 extending through the same, and its lower end extends dow below the bottom of the hollow shaftand below the bevel gear I99, as shown in Figure 1.

The bottom of the shaft 69 fits within a socket I I3 on the extension I I4 of the regulating member I I6. This regulating member is slidably mounted on a rod HT, and is operated by means of a screw I I8 mounted on a bracket I I 9, which said bracket is in turn mounted on the bearing bracket I2I. The screw III has a bevel gear I22 which meshes with a bevel gear I23 on the end of a shaft I24 mounted in the upstanding bearing I26, and said shaft has a hand wheel I2I on its outer end, so that upon the turning of said hand wheel, the bevel gears I23 and I22 will be operated, which will turn the screw H9, and operate the member I I6 to raise or lower the shaft 68, and thus either push the upper turret 63 upward to increase the capacity of the telescopic measuring cups of the lower and upper turrets 59 and 63, or by drawing the shaft 68 downward permit the weight of the hopper and turrets 59 and 63 to lower the said shaft 68, and thereby decrease the capacity of the said telescopic cups. The regulating member II6 has an overhanging arm I28 to which is attached a link I29. This rod has its upper end fixed to a toothed rack I 3I which is slidably mounted at the rear of an indicating dial I32. This dial is mounted on the partition or plate 54. This slidable mounting consists of a slot I33 in said rack, and pins or screws I34 passing through said disk and through said slot, so that the rack is freely movable upward and downward, when the overhanging arm I 23 is moved by the regulation of the shaft 69. The toothed rack I3I meshes with a pinion I36 centrally mounted on said indicating disk by means of a pin having a shoulder I 31 to which is secured a finger I38. The indicating disk I 32 is provided with a circle of closely spaced holes I39, which said holes are utilized for receiving the spring button I shown in Figure 6A.

In the canning industry, different packers have different systems for grading peas, etc., and in the case of peas may have four or more grades, depending upon the size of pea. Of course, small peas will pack considerably more compact than large peas, and therefore in changing from one grade to another, it will be necessary to alter the capacity of the telescopic measuring cups for measuring the peas to be deposited into the can. When, for instance, the machine is being initially used, and the proper regulation for a Number 1 grade pea has been obtained with the telescopic cups, one of the spring buttons "I can be slipped into the hole I39 indicated by the finger I38, and thereafter the machine need only be regulated until that finger points to the button in order that the operator will know that the telescopic cups are properly set for a Number 1 grade pea. In like manner, the Number 2, Number 3, and Number 4 grades may be set by the use of the buttons, after the telescopic cups are properly regulated for those grades.

In Figure 6 there has been shown a button I42 indicating where the finger I36 should point when the telescopic cups have been set for Number 2 grade. Figures 7 and 8 illustrate an indicating device for the telescopic cups which meas ure the liquid in the liquid tank 93. The end of the shaft 99 rests within the socket I43 in the extension I44 of the regulating member I46. This regulating member is operated by the screw I41 and extends up through the table 28, and is provided at its upper end with a bevel gear I46, which meshes with a bevel gear I49 on a shaft ISI. This shaft and the screw I" are both mounted in the bearing bracket I52, and the shaft I5I is provided at its outer end with a hand wheel I53, so that upon the turning of the said hand wheel, the shaft I5I will rotate the bevel gear I49 which, in turn, will rotate the bevel gear I48, and the shaft I41, and thus tend to raise or lower the regulating member I46 which tends to raise or lower the shaft 99 in the hollow shaft 95, so that the plugs 91 are either raised or lowered in the cups 96, thus changing the capacity thereof.

Of course, the shafts 69 and 99 may be split at X and Z respectively (see Figure 11), so that only the resulting short stub shafts at the top need be rotated, and when the machine is cleaned only the small stub shafts would be withdrawn from the hollow shafts. In such a case the lower part of the interior shafts may be fixed in the sockets of the adjusting members, as shown at S. (See Fig. 5.)

The regulating member I46 has an overhanging arm I45 to which is pivotally mounted a link I45, while the upper end of said link is pivotally mounted at I59 to a rack I3I identical with that shown in Figure 5. This rack 0perates a pinion I36 at the back of an indicating dial I55, which is identical in construction with the dial I32 shown in Figures 5 and 6, and the pinion operates a finger I in exactly the same manner as that explained in connection with Figures 5 and 6. The dial I55 is provided with a series of small holes I55 into which the spring buttons I4I are inserted when the proper regulation of brine is obtained for filling the cans, containing the several grades of peas, or other discrete solid matter. It can be readily understood that when small peas are inserted into the can, the percentage of voids will be much less than when large peas are inserted. Consequently, the telescopic liquid cups in the liquid tank 93 would have their capacities decreased, when the smaller peas are being put into the cans. However, the buttons will be inserted at the points on the dial to correspond with the buttons on the solid material dial I32, so that a Number 3 on each of the dials would indicate the regulation for the cups of the solid material on the dial I32, and the regulation for the liquid material on the dial I55.

The supporting frame 53 is provided with a liquid pot I54 which has ears I56 fastened to said frame by bolts I51. This not has a flat bottom I58 with an intake recess I59 and a discharge recess IGI. The discharge recess has an opening I62 which communicates with a spout I63 which has a flange I64 bolted against the outside of the pot by means of the bolts I66. This spout has its open end I51 directly over the line of travel of the cans A as they are fed to the star wheel 36. The side of the brine pot opposite-to the spout I63 has a nipple i68 adapted to receive a pipe I69 which extends to and communicates with the brine tank 93, so that the common level of liquid is maintained in said tank and pot. This pot has an upstanding bearing I1I while a rotary measuring device I12 has a central sleeve I19 which fits down over said sleeve and is provided with a pair of lugs m which strike against a pin I10 on the end of a shaft I11 which extends through the bearing I'll. The rotary measuring device has the major part of its bearing surface I10 flat and contiguous with the bottom I00 of the pot, and is provided with a pair of pockets I19 and III for obtaining a measured quantity of liquid from the recess I00 and carrying it around to the opening I02 from which it passes out through the funnel I" to the can A. This rotary measuring device I12 is operated by means of a gear I92 which meshes with an idler gear I09, which said idler gear meshes with a gear I94 on the can feeding shaft I99. The pockets I19 and III are each provided with a vent pipe I01 which has an overhanging lid I.00, so that said pocket may readily fill and discharge, while the overhanging lids I99 will prevent any dirt or dust from entering the said vent pipes.

Figure 9 shows the piping arrangement of the can filling machine wherein the supply of liquid consisting of brine, sauce, or other material, is fed from the pipe I09 to a valve I9I and from that valve through the pipe I92 to a valve I93 located in the bottom of the liquid tank 99. This valve I99 is operated by the ball float I94. The ball float I94 is adapted to maintain a level of liquid indicated at I96. Between the valve HI and pipe I92 is a union I91 which has a threaded nipple I99 from which a small pipe I99 leads and passes around, and is provided on its end with an elbow 20I having a nipple 202 which enters the tapered collar 203 of the cover plate 19 at a point directly below the hopper 11. This nipple communicates with small flaring holes 204, so that a small quantity of liquid is fed at the bottom of the hopper to provide lubrication to assist the discrete solid matter in dropping rapidly into the telescopic cups of the turrets 59 and 99 as said cups pass under said hopper. Mounted on the table 29 is a bracket 204 which has a collar 209 surrounding the pipe I92 for maintaining the same in place, while the bottom end of said bracket is provided with a ribbed extension 201 having a bearing 200 at its outer end, which said bearing houses a valve shaft 209, which operates the gate 2 in the valve I9I. This shaft 209 has a grooved collar 2I2 with fingers 2I9 resting therein, while governing balls 2 are fixed to arms 2I6 depending from said fingers so that when the shaft 209 is at rest the weight of the said balls will push the collar 2I2, and consequently the shaft 209 upward and seat the gate 2 firmly over the port 2I1 in said valve. The bottom end of the shaft 209 is provided with a small bevel pinion 2I9 which meshes with a bevel gear 2i 9 on a shaft HI, and the inner end of this shaft is also provided with a bevel pinion 222 which meshes with a bevel gear 229 on the can feed operating shaft I".

It will thus be seen that when the machine commences to operate by throwing in the clutch through the operation of the shipper handle 23 that the can feeding mechanism will be operated, so that the shaft I99 will be rotated. This rotation is communicated to the shaft 22l through the bevel gears 229 and 222 while the bevel gears 2 I 9 and 2 I 9 impart rotary motion to the shaft 209, thus throwing the governor balls 2 outward,

which motion through the operation of the toggle arms 2| opens the gate 2 opening the port 2" of the valve I9I.

When the machine ceases to operate, the governor balls 2I5 will assume the position shown in Figure 9 which will effectively close off the passage of liquid from the pipe I09 into the union I91 and pipe I92, so that no liquid will be fed through the pipe I99 into the bottom of the hopper through the small openings 20, and no liquid can seep in through the valve I92 to the liquid tank 93, and since the height of the liquid in the liquid tank 93 controls the height of the liquid in the pot I54, no additional liquid can be fed into such pot, and, therefore, there will be no danger of the brine tank and pot I94 overflowing.

Of course, it will be understood that while the machine has been described in detail showing certain specific constructions of mechanism to perform certain definite objects, the inventions themselves are of a broad nature, bringing into a high speed can filling machine, functions which are novel, and which have not heretofore been found in this art.

The pre-briner or liquid pot utilizes spare time of the machine in the feeding of the can to position for receiving its preliminary supply of brine or liquid, and when the discrete solid material is deposited therein, the liquid will be displaced, and will assume a higher level, so that less time will be required in the operation of the machine for depositing into the can the necessary amount of liquid or brine to completely cover the solid matter therein. Moreover, the several adjuncts herein described and consisting of the indicating means coupled with regulating means will be found of great benefit to canners and packers who heretofore have been compelled to resort to the cut and try" method for regulating the telescopic cups, and the liquid fiow being positively cut off by governing means operated by the operation of the machine will insure the complete cutoff when the machine is brought to rest.

Of course, the machine illustrated and described may be modified in many and various ways without departing from the invention herein set forth and hereafter claimed.
