As illustrated in the accompanying drawings, the improved filling machine comprises a supporting base 20, having an upwardly extending circular part which is hollowed out as shown at 21 to form a housing for a worm wheel 22 which is secured on a vertical operating shaft 23. This shaft is journaled in a bearing 24 formed in the base beneath the chamber 21 and extends upwardly through the housing cover 25'in which it is journaled. The clover 25 is secured to the portion 20 of the base by means of studs 26 and the central hub portion 25a of the cover is threadedly engaged by a hollow sleeve or standard 27 through. which the operating shaft 23 passes. The .upper end of the shaft 23 is tapered as shown at 23a4 to fit the correspondingly tapered bore of a hub member .28 secured to the circular top plate 29 of a rotatable head 30. The head 30 is secured against rotation with respect to the shaft 23 by a key engaging the tapered portion 23a and the hub 28. The extreme upper 'end of thc shaft23 is threaded for engagement by a nut, 31 which holds the hea-d 30 against vertical displacement. The head 30 comprises a plurality of measuring cylinders 33 which register with apertures 34 formed in the top plate 29 and extend downwardly therefrom, being closed at their upper ends by relatively thin cover plates 35 which engage vannular f recesses around the openings 34 and which are maintained in place by cross bars 36 secured to the plate 29 by studs 37. The lower end of each measuring cylinder 33 is closed by 'a plate 38 and the entire group of cylinders 33, of which four are illustrated in the present embodiment, is surounded -by a depending sheet metal skirt 39 which is attached to an annular iiange 29 formed on the under side of the outer portion of the top plate 29. The skirt 39 is cylindrical in form and extends downwardly to the lower edges of the cylinders 33, being beaded at its lower edge as shown at 39.

The head 30 with its measuring cylinders 33 is adapted to carry the cans to be filled and to rotate on the standard 27, durin which time the grease or other liquid to e filled into the cans is forced into the cylinders 33 and discharged froml these cylinders successively into the cans. The rotation of the head 30 is effected through driving connections to the operatingshaft 23 upon which the worm wheel 22 is mounted. The worm wheel 22 meshes with a worm 40 whichis fixed on a horizontal shaft 41 journaled in bearings 42 secmd'to the lateral extension 20" of the base. This shaft 41 has a stepped pleillley 43 xed thereonand is driven by a t 44 which connects this stepped puley with mother stepped pulley 45 secured on a htizontal driving shaft 46. The shaft 46 is journaled in a bearing 46'* secured to the extension 20" of the base and it is also journaled in bearings carried by the housing of a pump 47 by which the grease or other liquid is pumped to the measuring cylinders 33. The shaft 46 has a sprocket gear 48 fixed thereon and this gear is driven by a sprocket chain 49 connected to another sprocket gear 50 fixed on the shaft 51 of a driving motor 52. The driving motor 52 and the pump 47 are both mounted on the base20J and the motor is connected in an electric circuit by suitable connections, not shown, which may,

if desired, be arranged to permit adjustment of the speed of the motor.

The pump 47 is of the centrifugal type and the grease or other liquid to be filled into the cans is drawn into the pum chamber through an inlet conduit 53, being subsequently discharged from the pump case through a discharge pipe 54 which extends upwardly, as shown in Fig. 1, and thence horizontally as shown at 54a. The horizontal portion of the discharge pipe has a valve 55 connected therein which is operated by a handle 55a to permit the flow of grease to be shut off when desired. A pressure gauge 56 is connected in the pipe 54 to indicate the pressure Aof the grease being forced from the I pump to the measuring cylinder 33. The horizontal portion 54 of the discharge pipe is connected through an elbow 57 with a short vertical extension 54" which is threadedly engaged at its lower end by the coupling sleeve 58. This sleeve is engaged on its lower end by another sleeve 59 havin a collar 60 threaded thereon and provi ed with an overhanging annular flange 60l which engages the upper side4 of the outwardly directed annular flange 58 formed on the coupling sleeve 58. The sleevei 59 threadedly engages av tubular .threaded member 61 which in turn has a threaded engagement with an aperture 62 formed in the upper side of a four-way coupling 63. The chamber 63a of the coupling member 63 has communication with four branch openings 63b each of which is threadedly engaged by a relatively short horizontal outlet plpe 64. These outlet pipes are connected through e1- bows 65 with downward extensions 64 which are mounted adjacent the cylinders 33 to rotate with the head 30. During the rotation of the head, the discharge pipe 54 and the connected coupling sleeve 58V remain stationary while the lower coupling sleeve 59 and its collar 60 revolve withthe flange 60L sliding over the flange 58'l 'and forming a fluid-tight joint.

Each4 branch supply pipe 64 extends vertically downward through an aperture 66 in the ,top plate 29 of the head in a position adjacent to and radially inward from one of the cylinders 33, so that one branch supply pipe .64 is adapted to supply grease or the 4 tical portion64 of each branch supply pipe is connected to an elbow 68`with a horizontal extension 64b which communicates with a three-way. connector 69. Each'connector has a pair of horizontally directed pipes 70 and 71 leading therefrom and communicating with the casings f the valves 72 and 73, respectively. VEachvalve casing has an internal cylindrical chamber and these chambers contain the rotatable valve members 72 and 73a. TheY valve member 72 has a passage 74 extending therethrough and communicating with a rightangularly disposed branch passage 74". The valve member 73 is similarl provided with aipassage 75 extending t erethrough and communicating with a branch passage 7 5. The valve casing 72 has one port 76l communicating with a pipe 70 and two other ports 76 and 7 6c each communicating, respectively, with the adjacent cylinder and with a nozzle through whlch the greaseis filled into the can. When the valve member 72 is in the position shown in Y Fig. 7, a communication is established from the pipe 70 through the port 76,val"ve passages '74 and 74l and port 76", with a p1 bows and other connections with the bottom of the adjacent cylinder v33 through its lower wall 38. AWhen the 'valve member 72 isturned throu h ninety degrees to occupy the position s own in Fig. 8, a communication is established through the valve casing from the pipe 77 through' the ports 76b and '76 to a vertical discharge p1pe'78 which extends upwardly adjacent the cylinder and communicates with one of the discharge nozzles 80. The Vvalve casing 73 is similarly provided with a port 81 communicating with the pipe 71 and two other aligning ports 81 .and 81. When the'valve member 73' is in I the position shown in Fig. 8, a communica- Bti tion is established from the pipe 71 through the port 81, valve passages 75 and 7 5f and port 81" with a pipe 82 which communicates with the chamber of the adjacent cylinder 33 through the sideV Wall thereof substan- 'tially midway between its upperv and lower ends, as shown in Fig. 1. When the valve member 7 3 is turned to the position shown in Fig. 7, a communicationis, established from the side of the cylinder 33 through the pipe 82, port 81", valve passage 75 and port '81 with a discharge or outlet pipe 79 which extends upwardly adjacent the cylinder and terminates in another discharge nozzle `8O located abovethe top plate 29 of the head 30.

Each measuring cylinder 33 is thus provided with two outlet pipes 7 Sand 7 9 and with illustrated more particularly in'` two connected discharge nozzles and the der. Each cylinder 33 is therefore provided with acvlindrical piston 85 which divides the space within the cylinder into a lower measuring chamber 86 and "an-upper measuring chamber 87. The grease forced into the cylinder through the pipe 77 passes into the.

chamber 86 and thereby forces the piston 85 upwardly, thereby expelling any grease in the ychamber 87 through the communicating discharge ipe 82 which communicates with the space 8 through the side wall of the cylinder. In a subsequent operation, the grease is forced under pressure into the space 87 `thereby causing the piston 85 to move downwardly and force the grease outwardly from the space 86 through the pipe 77 and the connected discharge pipe 78. In order to vary the quantity of grease drawn into the cylinder 30 on one stroke of the piston 85, the upper'portion of each cylinder is partially occupied by a cylindrical filler block 88 which pe is carried by an adjusting screwr 89 having 77 lwhich communicates through suitable e1- a threaded engagement with a hub 36a of the .bar 36 which extends'across the top end of the cylinder above the cover plate 35. When the iiller block 88 is adjusted downwardly by turning the screw 89, Having the hand wheel 89'L at the upper end thereof, the path of travel'of the piston 85 is thereby limited so that the volume of grease drawn into either chainber 86 or 87 upon one stroke of the piston is reduced. By suitably 'adjusting the position of the ller block 88, the quantity of grease drawn into the cylinder on one stroke of the piston 85, and sub uently ejected therefrom on a reverse stroke o the piston, may be regulated to suit the capacity of the cans being filled.I The iller block 88 is' provided with andwith the cross bar 36 so that' the block 88 is prevented from turning when being adjusted by the screw 89. Each piston 85 is preferablv provided with suitable packing rings of leather or the like to prevent the escape of grease or other liquid from one measuring chamber 86 or 87 to the other.

The valve members 72l and 73n are auto.-

matically operated during the rotation of the head 30 to cause grease to be drawn into and discharged from the various measuring cylinders 30 at the proper intervals during theA rotation of the head. Each valve member 7 2 has a shaft extending through the wall of its casing 72 and connected to .an intermediate part of an operating lever 92. Each valve member 7 3a is similarly provided-with a pro. jecting shaft which extends through the wall of its casing 73 and is connected to the intermediate part of an operating lever 93. The o posite ends of these levers 92 and 93 are pivotally connected to the ends of a pair of connecting links 94. These links are also pivotally connected to a trip lever 95 having a body portion 95 which extends parallel to the levers 92 and 93, being pivotally connected to the links 94 at the points 96. Each trip lever 95 has an operating arm 95 extending toward the outer side of the head 30 and directed at an angle of about forty-five degreesv to the body portion 95. Each trip lever 95 is also provided with a tangentially extending operating arm 95 which is directed at an angle of forty-five degrees to the body portion 95a and at an angle of ninety degrees to the operating arm 95. These operating arms 95 and 95 are adapted to be engaged by stationarilymounted rollers during the rotation of the head 30 forthe purpose of shifting the links 94 and thereby operating the valve levers 92 and 93. As shown in Fig. 6, the arm 95b is adaptedto be engaged by an outer roller 98 While the inwardly projecting arm 95 is adapted to be engaged by an inner roller 99. The roller 9,8 is rotatably mounted at the upper end of a post 100 which extends upwardlyfrom the base 20, as shown in Fig. 1, and the roller 99 is rotatably mounted on a pin 101 which extends upwardly from the housing cover 25. Y

The operation of the valve mechanism 67 may thus be understood by reference to Figs. 5, 6, 7 and 8. In Fig. 7 there is illustrated the relative positions of the parts of the Y valve mechanism 67 when the outer arm 95b of the trip lever is 1n engagement with the outer roller 98, corresponding to the lower set of valve mechanism 67 illustrated in Fig. 6. 'After the head 30 has rotated through one hundred and eighty degrees, the inner arm 95 of the triplever is brought into engagement withthe inner stationary roller 99, as

- shownin the upper part 'of Fig. 6, and that arrangement of the parts, on an enlarged scale, is illustrated in Fig. 8.- Although two different sets of valve mechanism are shown in these different positions in Fig. 6, it will be understood that each of the four valve mechanisms passes successively through each of these stages. When the inner arm 95b of the trip lever of a particular valve mechanism is in enga ement with the outer roller 98, as shown- 1n ig. the valve member 72l is turned so tnat a communication is established from the supply pipe 64 and'branch pipe through the valve casing 72 to the pipe 77.which communicates with the bottom chamber 86 of the adjacent measuring cylinder\33.V The grease is then orced into this chamber 86 under pressure by the action of the pump 47 until the piston l85 is forced to the upper limit of its travel as determined by the position of the filler block 88. As this operation of `illing the space86 goes on,\the head 30 continues to rotate and,-during this rotation, the upward movement of the piston 85 forces the grease which haspreviously been drawn into the space 87 outwardly '5 through the pipe 82 and 'thence through the valve member 7 3, occupying the position shown in Fig. 7, to the outlet pipe 79 through which the grease passes to a discharge nozzle and is delivered by that nozzle to one of the cans 105 positioned on the top plate 29.

This filling of the can 105 continues 4during the rotation of the head 30 until the piston of that measuring cylinder reachesv the upper limit of its travel. The period ottime during which this filling operation takes place will depend upon the` speed of operation of the pump and the capacity of. the cans being filled but it will have been completed before the cylinder and its valve mechanismy 67 reaches the reversed position shown in Fig. 8 at the end of one hundred and eighty degrees of travel. When that reversed position is reached, the inner arm of the trip` lever 95 is engaged by the' inner roller 99 thereby moving the valve mechanism to the kposition shown in Fig. 8. A communication is then established from the supply pipe 64 through the pipe 71 and through the valve member 7 3a to the pipe 82 leading to the space 87 above the piston 85 in the associated measuring cylinder 22. The grease then flows intol the space 87 under the pressureexerted by vthe pump 47 and at the same time the grease previously forced into the space 86 beneath the piston is discharged'therefrom through the pipe 77 and thence through the valve member 72, occup in lthe position shown in Fig. 8, and final y t rough the.pipe\78 to one of the discharge nozzles 80 where it is delivered to another of .the cansv105. This filling of the can from the outfiow through the pipe 78 continues as the cylinder and lts valve mechanism pass around in the direction of the arrow 206 from the'uppermost p0- sition shown in Fig. 6 toward the lowermost position shown in that figure. Thus,

vduring one 'complete revolution of the head other measuring space of that cylinder is.

discharged into a can.

The filling of heavy grease and the like into cans has heretofore resented diiiiculties due to the fact that i the grease be discharged from the nozzle at avpoint adjacent the top of the can, the grease may 11e up in irregular fashion in the can an leave air spaces or voids yso that the can does notv become entirely filled with grease. One of the important features of the present inven- 1l tion is the provision of improvedmeans for 1 counter-bore 107 of the main nozzle 80 and which may be moved downwardly into a can 105. when the can is positioned on the top plate 29 of the rotatable. head 30. The

upper end of each'nozzle extension 106 Ais i* pivotally connected to the lower end of a rod 108 which is slidably mounted in a vertical sleeve 109 formed integrally with or secured to the nozzle and extending upwardly therefrom, as shown in Fig. 10. The rod 108 extends 4[above the sleeve 109 and is engaged by a collar secured in adJusted position thereon ,by means of a set screw 111. Thls collar 110 may be adjusted on the rod 108 to limit the extent of downward movement i" of the nozzle extension 106 within the nozzle 80. Means are provided for elevating the rods 108 and their connected nozzle extensions 106 and the cans are placed beneath the nozzles .on the plate 29 while the members 106 are elevated. As the head 30 continues to rotate, the rods 109 arev released so that the nozzle extensions- 106 are successively permitted to drop by gravityI into the respective cans positioned beneath them.

The mechanism for elevating the nozzle extensions 106 at the the rotation of the head 30 is shown particularly in Figs. 9 to 15, inclusive, and it comprises a circular guide plate mounted on standards 116 which are'secured to the hori zontal portions of the pi 64 and having a central aperture 115n -w ich is en aged b the coupling sleeve 58 previously escri The guide plate 115 has a downwardly and outwardly inclined upper annular surface 115a and this surface has formed therein a plurality of downwardly inclined-guides 11i vlocated in radial planes each of vwhich includes the axis of one of the rods 108. Slidably mounted in each guide 117 is a bar 118 and each of these bars 118 is pivoted at 119 to a connectin rod 120 having its lower end secured to a c evis 121, shown in Fig. 10, the

posite sides ofV one of the sleeves 109. T e arms of the arms of which extend on o proper location during clevis are engaged by a fixed pin 122 which passes through slots 123, formed in the opposits side walls of the sleeve 109, and closey fits an aperture in the rod 108. Rollers 124 are mounted on the pin 122 between the rod 108 and the arms of the clevis 121 so that these rollers travel in the slots 123 when the rod 108 and its connected nozzle extension 106 move vertically. The downward movement of these valve extensions takes i? place by gravit as previously explained, ut the upwar movement is eiected b means of a cam 125 enga 'n h extend upwardly from t e hars 118 carried by the guide plate 115. The cam 125 has a hub 127 which is secured to the stationary portion 51..b of` the supply pipe by means of set screws 129. The body'portion of the cam extends outwardly and downwardly pins 126 whic parallel to the surface 115* of the guide plate and isv provided with a flange 125l directed downwardly at right angles to the surface 115. The inner surface 125" 125 coacts with the ins 126 and the distance of this surface 125? ro`m the axis of rotation of the head 30 decreases in the direction of rotation of the head which is indicated in Fig.'12 by the arrow 130. As the bars 118 and their upwardly extending pins 126 are' of this flange carried around by ther rotating guide plate 115, the pins 126 are brou ht successively into engagement with the ownwardly extending inclined surface 125" of the stationary cam. This moves the bars 118 inwardly and operates through the connect' rods 120 to effect an upward movement of t e nozzle extensions 106, which are thereb withdrawn from the cans 105. This with rawal of the nozzle extension from the cans should preferably take place, in the embodiment lllustrated, in the position indicated at 1,31 vin Fig. 2, and the surface 125 is provided at its inner portion with a part 125 whichis substantially concentric with the axis of rotation of the head so that there is a period during which each nozzle extension 106 is heldin its extreme elevated fposition to rmit the operator to remove a lled can an replace it by an empty can. The cam 125 may be adjusted in lts an ular position on the pipe 54" to cause this eevation ofthe nozzle extensions to take place at any desired point in the rotation of the head and the extent of upward movement of the nozzle extension by `the external- 4lus the `fillingof the cans 105 may be caused to take Aplace substantially as illustrated in Figs. and 15.' In Fi 13 the nozzle extension 106 is shown extending below the lower end -of the main nozzle 80 to a position wherein its may be regulated by adjusting the lenhs ,12

mouth is located adjacent the bottom of the can 105 and the grease 133 being discharged from the nozzle is filling the can from the bottom upwardly, the surface thereof being l indicated generally at 133B. As the filling continues, the upper surface of the grease rises upwardly around the nozzle'extension 106 as shown at 133b in Fig. 13. The filling continues until a point is reached when the W can is nearly filled where the surface of the grease approaches the top of the can as shown at 133c in Fig. 14, while the mouth of the nozzle remains near the bottom of the can. In l15, the can 105 is shown entirely filled l5 with grease and the nozzle extension 106 has been withdrawn therefrom by the action of the cam 125.

- Although one form of the invention has been shown and described by way of illusm tration, it will be understood that it may be constructed in various other embodiments.
