'Ihe present invention relates generally to improvements in mechanism for delivering quantities of diverse material to each of a succession of receptacles, and relates more specifically to improvements in the construction and operation of automatically functioning machines for partially or completely lling cans or other receptacles with charges of several kinds of material.

An object of the present invention is to provide an improved receptacle lling machine, which is simple in construction, highly eflicient in operation, and which avoids excessive waste of material when no receptacle are in position to receive the charges.

Another more specific object of my invention is to provide an improved machine for delivering independent quantities of several kinds of material to each of a succession of receptacles, and wherein discharge of material from the several material delivery devices is automatically stopped when the succession of receptacles is interrupted.

A further specic object of the invention is to provide a new and useful can filling assemblage which is adapted to deposit a measured batch of solids such as peas, and a. .charge of liquid such as brine into each o-i a series of cans or the like advancing at relatively high speed along a dcnite path.

Still another specific object of this invention is to provide an improved no-can-no-flll device for receptacle fillers, and especially for filling machines which automatically deliver independent batches and charges of several kinds of material to receptacles.

An additional specific object of the present invention is to provide an improved receptacle filling machine which is durable in construction, safely manipulable, highly sanitary, and which may be installed and operated at moderate cost.

Another speoic object of my invention is to provide an improved Ican ller or the like, which may be readily assembled and dismantled, and wherein waste of materials is reduced to a minimum.

A further specic object of the invention is to provide an improved filling machine having normally movable measuring pockets for some of the material, and wherein the motion of these pockets is automatically arrested so as to positively prevent discharge of material therefrom when no receptacle is in receiving position.

Still another specic object of this invention is to provide an improved receptacle filling machine having a constantly operating pump for delivering charges of liquid such as brine to successive receptacles, and wherein the delivery of liquid is automatically prevented when no receptacle is in charge receiving position.

Another specific object of my invention is' to provide improved instrumentalities for insuring proper ow of materials such as llegumes and liquid through the passages and pockets o-f a can filling machine or the like, so that bridging of solids and proper ow of liquid will be assured.

These as Well as other objects and advantages of the present invention will be apparent from the following detailed description.

While the several features of my present improvement have been shown herein as being specifically embodied in a machine especially adapted to deliver a, pre-measured batch of legumes such as peas and a charge of liquid such as brine to each of a succession of sanitary cans. it is not my intention or desire to unnecessarily restrict the scope or utility of the invention by virtue of such specific embodiment.

Referring to the drawings, the improved can filling machine shown therein, comprises in general a main frame having an approximately horizontal deck I0, a pair of sub-frames II for supporting the deck, and three upright posts or co1- umns I2 rigidly attached to the deck; a-rotary upright shaft I3 journalled in a central bearing I4 carried by the deck I0; a series of can hooks I5 secured to the shaft I3 above the bearing I4 and resting upon a thrust bearing I6; a can guide I1 and an annulartrack I8 carried by the deck I and cooperating with the hooks I5 to conduct cans I9 in succession around the axis of the shaft I3; a member 28 securedto the shaft I3 above the can hooks I and providing an annular series of eight material delivery chutes 2| and a similar series of segregated liquid distributing and delivery chambers 22 disposed outwardly of and communicating with the adjacent chutes 2| through slots 23; a normally fixed plate 24 detachably secured to the upper ends of the columns I2 directly above the chutes 2| and chambers 22 by means of nuts 25, and having 'a central bearing 26 in which the upper end of the shaft I3 is journalled; an annular sexies of eight legume measuring pockets 21 formed by a lower section element 28 rotatably supported upon the plate 24 and centered by an annular ridge 29 formed integral with this plate, and coacting telescopically with an upper pocket section element 30 which is adjustable vertically of the lower element 28 to vary the sizes of the pockets 21; a normally fixed upper support or'housing 3| in which the upper pocket element 38 is journalled for rotation and which provides a mounting for the legume supply hopper 32; mechanism for revolving the pockets 21 between the plate 24 and housing 3 I, and about the axis of the shaft I3; a centrifugal pump 33 suspended from one of the sub-frames II and being operable to withdraw liquid from a liquid supply reservoir 34 suspended from one of the fixed columns I2 of the main frame; a conduit 35 connecting the discharge fitting 36 of the pump 33 with the successive distributing chambers 22 through a discharge fitting or nozzle 31, the conduit having a control valve 38 and a shut-off valve 39 therein; mechanism for feeding cans I9 in succession to the can hooks I5; mechanism for delivering the successive filled cans |9 from the machine; other mechanism for imparting motion to the various normally movable parts of the assemblage; and a no-can-no-flll assemblage for automatically preventing delivery of legumes from the pockets 21 and liquid from the pump 33 through the chutes 2| when no cans I9 are in position to receive the charges.

The main frame is preferably of simple and durable constructionI and the sub-frames II which are rigidly inter-connected at their upper ends by the deck I0, may also be additionally connected to each other at their lower portions by a cross-brace 40, see Fig. l. The posts or columns I2 which are rigidly attached to the frame deck I0, may be formed of central bolts surrounded by hollow tubes of such length that they will properly space the plate 24 and the chutes 2| from each other and from the tops of the cans I9 which are to be filled. By varying the height of the columns I2 and by changing the elevation of the chute supporting member 20 relative to the deck ID, cans I9 of various heights may be handled. The member 20 is secured to the central shaft I3 by means of a spline 4| and set screw 42 in order to permit vertical adjustment of the member 28; and the can hooks I5 are keyed to the shaft I3 above the guide and thrust bearings I4, I8 and supports the weight of the member 20 through an adjusting sleeve 43 the upper end of which has internal screw threads coacting with the threaded central hub of the member 20, and the lower end of which rests directly upon the can hook hub. 'I'he position of the member 20 should preferably be such that the lower fianged ends of the chutes 2| wi11 be in close proximity to the upper open ends of the successive cans I9 as the latter are advanced around the axis of the shaft I3 within the guide I1 by the revolving can hooks I5. The normally fixed guide I1 and can supporting rail I8 may be readily removed from the supporting deck I8, and the liquid supply reservoir 34 may be anchored to any of the fixed columns I2.

As previously indicated, the plate 24 which is supported by the fixed columns I2 is stationary, and the journal bearing 26 carried by this plate cooperates with the journal bearing I4 on the deck I8 to rotatably support the shaft I3 and the elements carried thereby. The pockets 21 which are formed by the telescopically cooperating lower and upper elements 28, 38 are normally revolvable about the axis of the shaft I3 and about the annular ridge 29 of the plate 24, simultaneously with the chutes 2| and cam hooks I5, but independently thereof. This independent revolution of the legume measuring pockets 21 is accomplished by a counter shaft 44 disposed parallel to the shaft I3 and having upper and lower sections journalled in bearings 45, 46 and flexibly interconnected by a resilient coupling 41. The bearing 45 is carried by the fixed plate 24, and a gear 48 secured to the upper extremity of the upper section of the shaft 44 meshes with an idler gear 49 journalled on a fixed stub shaft 58, while the idler gear 49 in turn meshes with teeth 5I formed integral with the periphery of the lower pocket forming element 28, see Figs. l, 3 and 6. The lower bearing 46 is formed in a casing 52 which is rigidly but detachably secured to the stationary deck I0, and it will be noted that When the counter shaft 44 is rotated the pockets 21 will revolve to first cause the open upper ends of the element 30 to successively communicate with the hopper discharge opening 53 formed in the hopper support 3| and shown in dot-and-dash lines in Fig. 3, and to subsequently cause the lower open ends of the lower elements 28 to communicate with the chutes 2| through the opening 54 formed in the fixed plate 24 and shown in solid lines in Fig. 3.

While the legume supply hopper 32 is at all times fixed against rotation relative to the axis of the shaft I3, it is adjustable vertically with the support or housing 3|, with the upper pocket forming element 38 when the capacities of the pockets 21are to be varied. The mechanism for simultaneously vertically adjusting the hopper 32, housing 3| and element 38, while preventing revolution of the housing 3 and hopper 32, is shown in Fig. 3 and may comprise two parallel vertical guide rods 55, 56 secured to the periphery of the fixed plate 24 and slidably engaging bored holes in the housing 3|; and an intermediate vertical adjusting shaft 51 journalled against axial movement in the fixed plate 24 and having at one end screw threads coacting with a threaded hole in the housing 3| while its opposite end is provided with a manipulating hand wheel 58. This assemblage is obviously such, that by turning the shaft 51 with the aid of the hand wheel 58, the housing 3|, hopper 32 and the upper element 30 may be moved up or down without interfering with free rotation of the pocket forming elements 28, 30.' The rods 55, 56 and shaft 51 while avoiding obstruction to the rotation of the pockets 21, positively prevent the hopper 32 and housing 3| from rotating, and the periphery of the housing 3| may be provided with a removable sealing ring 59 coacting with the periphery of the revolving element 30 to center the latter relative to the axis of the central shaft I3 and ridge 29. The housing 3| is also provided with a recessed portion 60 above the path of travel of the pockets 21, which serves to level off the measured batches of legumes without crushing the same, after the pockets 21 have passed the hopper discharge opening 53, see Fig. 1. The upper pocket forming element 30 is rotatably suspended from the hopper support 3| by means of a. central bevel gear 6I and a cap screw 62, the gear 6I being journalled in a central bore in the housing or support 3| and meshing with a bevel pinion 63 secured to an inclined agitator shaft 64 journalled in a bearing 85 which is carried by the lower side wall of the hopper 32. A curved agitator blade or arm 66 is secured to the end of the shaft 64 within the hopper 32 directly above the discharge opening 53; so that when the upper pocket element 30 is being revolved by virtue of its telescopic coaction with lower element 28, the agitator arm 66 will also be revolved within the hopper 32 over the opening 53 and bridging of legumes across this opening will be positively prevented. The gears 6I, 63 are normally concealed and protected by a removable cover 61 secured to the hopper supporting housing 3|.

The mechanism for delivering the successive empty cans I9 to the can hooks I5, guide I1 and rail I8, is of relatively well known construction, and comprises a constantly revolving tapered drum 68 having a helical can feeding projection 69 at the discharge end thereof, adapted to deliver the successive empty cans I9 in properly spaced relation in front of the advancing hooks I5, within the guide I1 and onto the track I8.

The drum 68 is journalled for rotation on the deck I and is provided with a hand wheel 10 for effecting manual rotation thereof. The mechanism for delivering the successive filled cans I9 from the zone of lling, is likewise of well known construction and comprises a horizontal disk 1I mounted on a rotary shaft 12 and cooperating with the hooks I5, guide I1 and rail I8 to automatically discharge the loaded cans in succession, see Fig. 2. The mechanism for driving the receptacle lling machine during normal operation thereof, consists primarily of a main horizontal drive shaft 13 -journalled in bearings 14, 15, 16 and having a driving pulley 11 and a clutch 18 at one end thereof; a bevel pinion 19 secured to the opposite end of the drive shaft 13 and meshing with a bevel gear 80 secured to the lower end of the central shaft I3, so as to impart rotation to the latter; a. gear 8| secured to the shaft 13 between the bearings 14, 15 and meshing with a pinion 82 secured to the pump driving shaft 83; and a bevel gear 84 secured to the shaft 13 between the bearings 15, 16 and meshing with another bevel gear 85 rotatably suspended by a. bushing 86 from the lower headed extremity of the counter shaft 44, see Figs. 1, 2 and 5.

The improved no-can-no-nll mechanism which constitutes an important feature of my present invention, is best shown in Figs. 1, 4, 5, 6 and 1 of the drawings, and comprises generally a rod 81 slidable in bearings 88, 89, 90 formed integral with the casing 52 in which the count-ershaft 44 is journalled; a can engaging shoe 9| secured to one end of the rod 81 and formed to engage the bottom seams of the successive cans I9; a I

compression spring'92 embracing the `medial portion of the rod 81 and coacting at one end with a collar 93 secured to the sliding rod, while its opposite end reacts against the intermediate bearing 89; an arm 94 rigidly secured to the rod 81 between the bearings 88, 89 and having a roller 95 journalled at its upper end; a clutch collar 96 rotatable with and slidable along the countershaft 44 and having a laterally projecting quadrant cam 91 cooperable with the roller 95, the collar 96 also having jaws 98' at its lower end cooperable with complementary jaws formed on the upper end of the bevel gear a compression spring 99 embracing the countershaft 44 and coacting at one end with the collar 96 while its opposite end reacts against a stop plate |00 secured to the shaft 44; and a lever |0I secured to an end of the pivot shaft |02 which supports the shut-off valve 39, and cooperating with an actuating pin |03 secured to the outer extreme end of the rod 81. This nocan-no-ll assemblage is so constructed that when no can I9 is brought intoengagement with the shoe 9|, the rod 81, arm 94 and pin |03 will be retained by the spring 92 in the positions shown in Figs. 5 and 7, and the roller 95 will then coact with the quadrant cam 91. of the collar 96 to lift the jaws 98 out of driving engagement with the jaws on the revolving pinion 85 as shown in Fig. 6; while the pinv |03 will simultaneously coact with the lever I 0I to keep the shut-off valve 39 closed, as shown in Fig. 5.k However, when a can I9 engages the shoe 9|, the rod 81 will be pushed outwardly against the action of the spring 92, thereby rel moving the roller 95 from coaction with the cam 91 and lcausing the spring 99 to restore the driving connection between the gear 85 and shaft 44 through the collar 96; while at the same time opening the valve 39 through the lever I0| and pivot shaft |02.

The shut-off valve 39 is adapted to engage a seating |04 in the conduit 35; and the liquid iiow control valve 38 is of the gate type adapted to seat against a seating |05, this valve 38 being manipulable by means of a hand wheel |06. The centrifugal pump 33 is constantly operable at uniform speed, and has its suction opening connected to the liquid supply tank 34 by a pipe |01, and the discharge fitting 36 of the pump 33 may be provided with a connection |08 leading to the tank 34 and having a control valve |09 therein. This valve |09 may be utilized in conjunction with the control valve 38 to regulate the delivery of liquid from the pump 33 to the chambers 22 through the conduit 35, and is preferably closed so as to prevent by-passing of liquid from the pump to the supply tank when large cans I9 are being filled, so that the valve 38 is used as the sole means of regulation under such conditions of operation. The successive liquid distributing chambers 22 are segregated from each other by partitions I0 which are low enough to clear the nozzle 31 as shown in Fig. 4. All parts are accurately machined to avoid leakage and consequentwaste of material,

not occur.

and the various elements are also freely removable for inspection and cleaning.

During normal operation of my improved receptacle filling machine, and assuming the various parts to have been properly'r constructed and assembled, the hopper 32 should be supplied with an abundance of legumes such as peas, and the supply tank 34 should likewise be furnished with an abundance of liquid such asbrine. The drive shaft 13 may then be operated with the aid of the pulley 11 and clutch 18, to cause the central shaft I3 and the member 28 and can hooks I5 which are associated with this shaft, to revolve about the vertical shaft axis. Before cans I9 are supplied to the machine, the legume measuring pockets 21 will remain idle by virtue of the disconnection of the countershaft 44 from the gear 85 as shown in Fig. 6, and the shut-oli valve 39 will remain closed as shown in Fig. 5, so that the pump 33 will not be 20 delivering liquid into the conduit 35, but may be delivering a slight quantity of liquid back to the tank 34 past the valve |89. As the feed drum 88 delivers the successive cans I9 to the can hooks I5, each can engages the shoe 9| and pushes the rod 81 outwardly. This outward shifting of the rod 81 causes the roller 95 to disengage the quadrant cam 91, thus immediately making the spring 99 effective tc establish a driving connection between the revolving gear 85 and the shaft 44 through the collar 96, thus causing the gears 48, 49 to transmit rotary motion to the lower pocket forming element 28 and from thence to the upper pocket forming element 38. Simultaneously with this rotation of the pockets 21, the rod 81 will also open the shut-olf valve 39 as shown in Fig. 4, and depending upon the setting of the gate valve 38, quantities of liquid will be delivered from the nozzle 31 into the advancing chambers 22 located therebeneath. As each pocket 21 passes the hopper discharge opening 53, it receives a measured batch of legumes from the hopper 32, and as the loaded pockets pass over the opening 54 in the plate 24, the measured batches of legumes are deposited by gravity through the corresponding chutes 2| into the cans I9 located below these chutes. Before the legumes are thus delivered into the cans I9, some or all of the liquid deposited into the chambers 22 by the nozzle 31, will have passed through the slots 23 into the can, and these slots serve to prevent sudden delivery l,of the entire charge of liquid from each chamberl 22 so that undesirable splashing will The cans I9 after having received their charges of legumes and liquid, will be carried beyond the legume discharge opening' V54 and will eventually be delivered from the path of travel of the can hooks I5 onto the dis-charge disk 1I and from thence away from the ms.- chine. The same cycle of operations occurs witn respect to each can I9, and when no can is in position to receive a measured batch of legumes and a charge of liquid, then the shoe 9| will not actuate the rod 81, so that the pockets 21 will not. revolve and therefore cannot deliver material, while the shut-off valve 39 will remain closed and delivery of liquid will likewise be avoided.

From the foregoing detailed description-of the construction and operation of my improved machine, it will be apparent that the machine will function to automatically deliver a measured batch of legumes, and a quantity of liquid, to each v can I9 as it is advanced around the axis of the shaft Il. When n o can isin place, however, the legume measuring pockets 21 will not revolve, and the valve 39 will remain closed against its seating |84, so that waste of legumes and brine 5 due to the absence of a can I9 is definitely avoided. Each of the successive pockets 21 will be properly filled with legumes from the hopper 32 by virtue of the revolving agitator 88 which positively prevents bridging of the legumes over the hopper discharge opening 53. When the revolution of the pocket 21 ceases, the operation of the agitator bar 83 also ceases. The recess 88 in the housing 3| not only insures uniform filling of the successive pockets 21, but also avoids damaging the legumes at the top of each charge, and f fthe capacity of the pockets 21 may be readily and quickly varied by merely manipulating the hand wheel 58 and thereby raising or lowering the upper pocket forming element 30 relative to the lower element 28. While the hopper 32 and the housing 3| move vertically with the upper element 38. this element rotates whereas the hopper and housing do not rotate. 'Ihe resilient coupling 41 located in the counter shaft 44 which imparts rotation to the pockets 21, serves to eliminate shock when rotation of the pockets is started, and when the collar 98 is positioned as shown in Fig. 6, this collar which is keyed to the shaft 44 will not rotate until it is again drivingly connected to the bevel gear 85. 'I'he gear 85 is, however, constantly revolving upon the bushing 88, when the main drive shaft 13 is operating, so that the driving connection for the pockets 21 can be quickly restored whenever a can I9 is in proper position.

It will also be noted that the main control valve 38 cooperating with the valve |89 in the bypass conduit |88, serves to eectively regulate the quantity of liquid delivered to each of the chambers 22. When operating on large cans I9,

the valve 38 will necessarily be opened to a greater extent than when filling smaller cans, and the ei'fect of the adjustment of the valve 38 at such timesv will not be as noticeable as when the valve 38 is closed to a greater extent. It is 45 then preferable to close the auxiliary by-pass valve |89, and to depend upon-the valve 38 alone for regulation of the liquid quantities. The shuton valve 39 will be quickly closed by the spring 92 and opened by the successive cans I9 so as to insure proper delivery of liquid to the chambers 22 and to the cans I9, and the elongated slots 23 effectively distribute the successive charges of liquid and deliver the same through the adjoining chutes 2| to the successive cans I9.

As previously indicated, the entire assemblage may be readily assembled and dismantled and can therefore be kept in highly sanitary condition. The improved structure avoids damaging the legumes while insuring accurate pre-measuring thereof, and also reduces waste of materials to a minimum. All bearings are so constructed and positioned that the materials being handled will not be contaminated by lubricant, and the bearings are also readily accessible for lubrication.

The yimproved mechanism is obviously simple,

durable and compact in construction, and is entirely automatic and highly dependable in operation. My improved receptacle filling machine has proven highly satisfactory in actual commercial use and may obviously be utilized to handle not only peas and brine, but other similar materials.

It should be understood that it is not desired to limit this invention to the exact details of construction or to the precise mode of use, herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
