Application filed September 28, 1925. Serial as; 59,178.

The present invention relates to .nachine for treating grain with copper carbonate or other preparation or compound, to prevent smut, and to preserve the grain. and it is an object of the invention to provide a novel and ii'nproved machine whereby the grain may be treated in an eiiicient and practical manner and collected within a bag or sack. I V

Copper carbonate has been recommended by thell'nited States Department of Agriculturefor the treating of seed grain in order to prevent smut in all sections of the country. Copper carbonate being a. light and fluffy powder will, when agitated such as is necessary to mix the same with grain, float in the air in the form of dust. Tl his makes the copper carbonate obnoxious inasmuch as the mixing thereof in the open with the grain will result in the surrounding air be coming laden with the copper carbonate dust and same will be inhaled into the him of the person doing the mixing and others in the vicinity, and such dust becoming moistened in the lungs will become active, causing sickness.

It is an object of the invention to provide a machine for treating andsacking grain, especially seed grain, with copper carbonate or other powder, without the powder escaping.

A further object is the provision of novel sacking means in order that the treated grain may be sacked in a. practical and eiiicicnt manner \vithout creating dust, from the powder used, in the air surrounding the bag and machine.

Vith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wlierein, I

As shown, the machine is an elaboration of the grain treating machine disclosed in my Patent No. 1,274,180, granted July 30, 1918, said patented machine being used as a basis around and upon which the improvements are embodied. Thus, the present machine embodies a mixer of somewhat the same construction as disclosed in said patent, comprising a casing'l in which is mounted a wheel or rotor 2 that has blades orscoops for picking up fthe' grain delivered into said *a'sing and discharging same through the outlet opening l of the casing; The rotor or wheel 2 serves to agitate the grainas well delivering same through the opening l and said rotor is mounted on-a horizontal shaft 3.journaled for rotation in the'casing 1', as seen in Fig.3. Thef'grain that is discharged from the mixer is elevated within an elevator housingfi, aswi'll hereinafter more fully appear, the, grain passingfrom the .openingtof the mixer into the lower portion of the housing 5.

A grain receiving hopper G is provided at one side of the mixer casing 1 and the casing 1 has a lower inlet opening 7 at said side for the flow of grain from the hopper into the lower portion of the casing 1, so that the grain is picked up by the rotor 2. A vertical partition 8 is provided in the hopper 6 adjacent to the casing 1. to provide a vertical passage 9 leading upwardly from the opening 7, and said partition 8 has an opening 12 at its lower end for the flow of grain from the hopper through the opening 12 to and through the opening-'7, the grain flowing across the lower end or". the passage 9 down which the powder or other treatingmaterial is dropped, as will presently appear. The flow of grain to the mixer from the hopper is controlled by a valve 10 slidable along the partition 8 to be projected downwardly below the upper edge of the opening 12, and the valve 10 has an upwardly extending stem 11 that may be controlled manually by any suitable means in order that the feeding of the grain to the mixer may be controlled.

The powder feeder is located above the mixer for feeding powder down into the passage 9 to mix with the grain that enters the mixer. The powder is contained in a magazine or supply chamber 13 composed of two sections for purpose of adjustment to regulate the amount of powder that is ted to the grain. One section oi the magazine 13 comprises the side walls i l and 15, constituting three sides of the magazine. and having their lower ends secured to the top of a belt ca sing- 16. The other section of the n'ia a azine comprises a side wall 17 between the walls 15, and constituting); the fourth side of the magazine. Said wall 1'? has the outstanding doubled portions 18 fitting astride the walls 15, to prevent leakage ot the powder between the walls and 17, and the wall 1'? is adjustable between the walls 15 to ard and away from the wall ll to decrease and increase the cross-sectional area otthe magazine. The top of the casing; 16 has an opening 19 at the lower end of the magazine, and said opening is sutlicicntly large to correspond to the maximum separation ot' the walls 14; and l7. A. base plate 20 is secured to the lower end of the wall 1'? and portions 18 thereof. and is slidahle on the top of the casing 16, said plate 20 having the slots 21. receiving clamping bolts or other elements carried by the top of the casing 16 in order to hold the wall 1'? in place in its different adjustments. and permit oi the ad justment of said wall.

ithin th casing 16 is mounted an endless belt 23 which passes around the rollers 24 and 25 that are mounted on the horizontal shafts 26 and 27 journaled for rotation in said casing 16 The upper run of the belt 23 is disposed close to the top of the casing 16 under the opening 19, so as to form a moving bottom for the magazine. Thus, the belt in moving will carry with it a thin layer of powder from the lower end of the magazine. The. roller 25 is located above the passage 9, so that the powder will drop down into said passage, and a rotary brush is located below the roller for bruslr ing the powder from the belt Said brush 28 is mounted on a horizontal shaft 29 below the shaft 2?. The brush and belt are made to move simultaneously by means of an endless belt 30 extending around pulley wheels 31 secured on projecting terminals of the shafts 26 and 29.

The band of powder taken by the belt or apron 23 from the powder magazine l3 will be of a width corresponding to the spacing ot the wall 17 from the wall 14. Consequently, by moving the wall 17 closer to or farther away from the wall 14:. it is possible to regulate the amount of powder delivered from the powder magi zine to the passage 9. The thickness of the film or layer of powder on the belt or apron 22 will be substantially the same for different adjustments of the magazine 13, but the width of the band or layer of powder depends on the spacing; of the walls ll and 17 of the magazine. This band or layer 0t powder may be narrowed down when it is desired to decrease the supply of powder delivered to the mixer. The proportion of powder may also be varied by changing the near ratio so as to operate the powder feeder either slower or faster with reference to the remainder of the machine.

It is also possible to teed various powders down through the passage 9 to mix with the grain, and provision may also be made for feeding formaldehyde, vitrol and other liquids to mix with the grain.

The grain elevator comprises an endless belt or chain 32 within the housing 5 and passing around a lower pulley or sprocl-Iet wheel 33 and an upper pulley or sprocket wheel 34, which wheels are mounted on the respective shafts 35 and 36 iournaled in the housing- The endless flexible member 32 carries buckets 37 which dip up the grain troni the lower portion of the housing Ii and elevate the grain. The housing 5 has an inclined esitension near its upper end within which operates a secondary elevator comprising the endless belt or chain 39 passme around pulley or sprocket wheels ll and 4-2 at the lower and upper ends of the e: tension 38, respectively. Buckets 14:0 are hing'edly connected with the endless flexible member 39, and the wheels l-l and 42 are mounted on the shafts 44 and respective ly. Tie primary elevator including the buckets 37 discharges the grain from the buckets as they pass ver the wheel 34, thereby delivering the grain to the lower portion of the secondary elevator, and the lll fill

grain is caught in the buckets l and cried upwardly in the extension 38. The secondary elevator operates "at a higher speed than the primary ele ator so that the grain is discharged violently through the upper end oft-he extension 38 as the buckets pass around the wheel roller one swing away from said roller by centrifugal force. The buckets 4:0 rest-on the upper run of the exible element 39 as said buckets move upwardly,and the buckets are swung away from the-flexible element 39 as the buckets pass around the wheel. or roller ther'eb'y throwing the grain through the up per end of the extension 38; The bearings of the shafts and 423 are iireferably adjustable in or'der that the enidlessflexible elements'lQ and 39 of the elevators may be tightened.

The elevated grain fwhielris diseharged from the extension 3816f the elevator housing passesdovvnan'incline'd chute 4:6, and the lower endot't' the chute is connected to the top l7 -01 a tunnel shaped mini and sacking i ember, comprising the llGPL-J' l8 and depending spout 4:9. "The top 47 closes the hopper a8, and the'ehute 4:6, to prevent the esrapeot dust, and the chute 2-6 is located at one side of the center or the hopper so that the grain entering the hopper has a whirling motion therein before dropping down through the spout 49 into the sac; or bag 3' The spout is o'fa size to receive the sack thereon.

The spout d9 isprovided with a valve or closure to control the discharge of grain Thus, the lower end '50 the spout has openings 51, and a vertical shaft disposed axially within the hopper L8 and spoutl9 journaled in the top 4:? and bottom 50.,

and carries the wings of the valve. The wings 53 may be turned over the openings 51, as seen in Fig. 111, to shut oil the dis charge of grain from the spout 4:9, vith the valve in closed position, and the valve may beturned to remove the wings 53 from over the openings 51; is'seen in 10, so that the grain may discharge down through said openings 51. p

Below the spout l9 is mounted for vertical movement a bracket shelf 54 to siuapoi't th sacks S; The shelf 54F. has the back 55 pro vided with the rearwardly extending flange having the bearings 57 slidable on. parallel vertical guide rods 58. The lower ends of the rods 58. are seeured to a frame member 59 secured on the base 60 ot' the .lna- Chine and the upper terminals of the rods 58 he engaged within a bracket 61 secured to posts 62 that are secured on thebase 60.

For example, as shown, a cam 69 is pivoted to the ring above the flange 38 for clamping the edge portion 01"? on. said flange, the severa oi i cams or elan'iping elements niiay be u..:ed it (-2:- sired. The ring '67 is carried by a slide 7-,

that moves up and down on the rods 58 above the yoke- 65, and rods 71 connect the slide with the flange of the hraehet shelt, whereby the ring 67 is raised anlowered with the shelf The rods 7 slide through the yoke 65.

The nine no is driven by an electric motor 72 mounted on the base'60, or other source 01" power maybe used. A belt 'll'pasie. around a pulley wheel 73 on the armature shaft of the motor 72 and around a pulley wheel 75 of larger diameter secured on the elevator shaft thereby driving the elevat r direct from the motor, and a belt tightener 76 is used for tightening the belt 1 i, reference being had to Fig. 1. l pulley wheel 7'? on the shaft 36 is connected by a belt-78 with a pulley wheel'iS of smaller diameter on the shaft 43, whereby the see ondary elevator is driventroin the primary elevator. A gear wheel 80 on the shaft 35 meshes with a gear wheel 81 lllOUIli-(Efllll the trains, and a pulley wheel 82 is'rotutable with the gear wheel 81 and is connected by an endless belt with pulley wh el 84: seeure'd on the shaft 3, so that the rotor or" the mixer is operated simultaneously with the elevators. A belt tightener is proided for the belt 83, or a s 'irooluet chain can be used in lieuot the belt 83.

A reversing r is located betwen the shaft 91': and the shaft 3 from which the screw (ii is driven, in order to reverse the direction of rotation of the screw 6%. The reversing gear, as shown in Figs. 1, 2, 15 and 16, includes a supporting bracket 96 in which the shaft 94. is journaled, and a gear wheel 97 carried by the bracket 96 and meshing with a pinion 98 on the shaft 9 1.. A rocking bar 99 is fulerumed between its ends, as at 105, on the bracket 96 and its opposite arms carry the gear wheels 100 and 101 adapted to alternately mesh with the gear wheel 97 when the bar 99 is oscillated to opposite positions. The gear wheels 100 and 101 mesh with one another, and a sprocket wheel 102 rotatable with tae gear wheel 101 i connected by an endless sprocket chai 10 with a sprocket wheel 104: secured on t shaft 3 so that the wheel 101 is driven in one direction from the shaft 8, while the wheel 100 rotates in the opposite direction. Consequently, when the wheel 101 meshes with the wheel 97, as seen in Fig. 16, the

shaft 91- and screw 6 1 are rotated in the corresponding direction, whereas when the wheel 100 meshes with the wheel 97, as seen in Figs. 1 and 15, the shaft and screw 61 are rotated in the reverse direction.

The reversing of the screw 61- is obtained by the oscillation of the bar 99 to alternately engage the wheels 100 and 101 with the wheel 97. For this purpose, toggle links 106 and 107 connect the opposite arms of the bar 99 with the bracket 96. A lint 108 is comiected to the joint of the links 106, and a link 109 is connected to the joint of the links 107. Said links 108 and 109 are connected to an ev-ener bar 110 which is pivoted between its ends to a link 111 that is in turn pivoted to the lower arm of a lever 112 fulcrumed, as at 118, to the frame. The evener bar 110 distributes the strains between the links 108 and 109 when the lever 112 is swung to move said links 108 and 109 in either direction. A bar 11 1 pivoted between its ends to the bracket 96 has slots 115 and 116 in which the joints of the toggle links 106 and 107 are movable, in order to limit the movement of the parts. lVhen the lever 112 is swung to the position shown in Figs. 1 and 15, the links 108 and 109 are pulled upwardly, tl'iercby moving the oints of the toggle links 106 and 107 in the corresponding direction. lhe toggle links 106 are therefore broken, while the links 107 are moved slightly l38- ond a st sight line position. This will swing the bar 99 to remove the wheel 101 from the wheel 97 and bring the wheel 100 in mesh with the wheel 97. The links 107 moving slightly beyond a straight line or dead center position will lock the parts in this position. the joints of the toggle links being limited in their movement in the. slots 115 and 11.6 of the bar 11 1-. Vl hen the lever 112 is moved to its opposite position, as seen in Fig. 16, the links 108 and 109 are moved downwardly to the position shown in 16. The toggle links 107 are broken, while the links 106 are moved slightly beyond a straight line position, thereby swinging tie bar 99 to remove the wheel 100 from the wheel 97 and engage the wheel 101 with said wheel 97. The links 106 moving slightly be yond straight line or dead center position will lock the parts with the wheel 101 in nesh with the wheel 97.

Loose play or lost motion is provided for between the pinion 98 and shaft 94: to permit either of the wheels 100-101 to come into mesh with the wheel 97 before the power is applied to the shaft 941. Thus. a collar 117 is secured on the shaft 9 1 and said collar has a lug 118 cooperable with a lug 119 on the hub of the pinion 98. Vfhen the pinion 98 is rotated in one direction the lug 119 bears against one side of the lug 118 to drive the shaft 9 1 in the corresponding direction. When the rotation of the pinion 98 is reversed the lug 19 will move through more than one-half of a circle before contacting with the opposite side of the lug 118 to drive the shaft 91 in the corresponding direction. in this way, whenever the rotation of the pinion 98 is reversed, the pinion will turn almost a complete revolution before turning.

the shaft 9 1 with it, and this gives the gear wheel 100 or 101 an opportunity to mesh with the gear wheel 97 before the power is applied to the shaft 9% to rotate the screw 6 1 and move the shelf 5 1.

11 tripping derice is used for operating the control lever 112 of the reversing gear,.

and is in turn controlled by the movement of the shelf 54 to its extreme upper and lower positions. The tripping device includes a horizontal reciprocating bar 120 having a pin and slot connection 121 with the upper arm of the lever 112, so that said lever swung by the reeiprocatory motion of the bar 120. Said bar 120 is slidable in guides 122 that are secured to the legs of the casing 1 or frame of the machme, and

said bar 120 also has a lateral shifting movement in the guides. The bar 120 is pressed inwardly by means of rods 123 slidable in the guides 122 and outstanding loops 124, and coiled springs 125 surround the rods 128 and are confined between the loops 121 and shoulders or washers 126 on the rods 128 in order to yieldingly more said rods and bar 120 inwardly. The bar 120 is slidable across the inner ends of the rods 123, and said rods constantly urge the bar 120 inwardly.

A. disk 127 is secured on the shaft at the outer side of the bar 120 and carries a crank pin 128 arranged to alternately wipe along the ertical portions 129 and 130 carried by the bar 120. Thus, reference being had to the path of movement of the wiper pin 128,.

the pin 128 contacting with the portion 12 (the shaft 3 and d 1-. 127' mutating clockwise) all move the bar toward the 1'igl1t,-ar1d the pin 1.28 engaging and wining along the portion will move the bar 12. toward the left or forwardly. lVhen the ba 121) moved, inwardly by the springnes er rods 123, the portions'129 and 130 are e traeted from: the path of-movement of the pin 128 so that the bar 120 will remain in the position to which it has been slid lonniitudinally thereof.

The tripping; action obtained .by a rock shaft 131' located behind the bar 120 and iournaledin bearings 132 with whichthe guides-122 are provided. The bar 120 has ln s or portions 133 at its inner side adapteo to-enga 'e oppositesidesof the guides 122 for l'iolding the bar120 in either of its opposite positions; moved forwardly and shifted inwardly the lugs 133 engage inv front ofthe guides 122. whereas when the bar is slid rearwardly and shifted inwardly the lugs 133 engagreinrear of the guides 122. The rock shaft 131 has the cams 134 and 135 in front and in rear of the corresponding guides 122 and extending in. opposite directions. In the interme diate or neutral position of. the shaft .131 the cams 13:4.er-ztend downwardiy as seen in l 3; while the cams 135 project upwardly. Thus, if the lugs133eu3rage in front of the guides the proper, direction, the anus 134 will force the lugs 133 outwardly as seen in Fig. 7, thereby enabling thebar 120 tobe slid rearwardly. Similarly, if the lugs 133 are en- ;raged in rear of the" guides 122, and the shaft 131 is turned'in the opposite direct-1on the cams 135 move-the lugs-133 outwardly so that the bar 120 may he slid forwardly.

To assist inusupportinp; and guiding; th. bar 120. angle pieces 1361 are secured by means of bolts 139 orother clamping elementsto the-inner side of thebar 120. The

pieces 136 have horizontal slots 13'? receiving: the shaft 131 and assisting in guiding the bar longitudinally and laterally. "the pieces.136 also have vertical slots 138 reli'PlVlllQ the bolts 139 to permit of the bar 120 being adjusted vertically with reference to the shaft'131.

.1111 arm .140 is secured to the shaft 131 and is connected by a spring 141 with the adjacent post 6201' otherpart of. the frame,- in order to yieldingly hold the'shaft .131 in intermediate position.

The shaft :131 is turned in. opposite directions when the shelf 54 re ches its uppermost and lowermost, positions, toobtain the tripping action for reversing the operative connection between the screw 64' and driving Thus, when the bar 120 is 122' and, the shaft 131 is swung in.

A bar 143 secured to the lever 146 and carries a roller or member 149 at its upper end with which the slide 70 contacts when the shelf 54 and ring 67 reach their lowermost, position, therehydepressing the lever 146 and turning the pinion 1'42and shaft 131 counter clock-wise as seen in Figs. 2, 12, 13 and 14. This particular position of the parts is shown in A depending arm 150-is pivoted to the lower terminal of. the bar 148 and is raised by the flange 56 of the shelf 54 when said shelf reaches its uppermost po sition, (S, seenin v14, thereby swinging the lever 146 upwardly so that the rack 143 rotates the shaft 131 clockwise. l i hen the shaft 131 is turned in either direction from intermediate orneutral'position, the arm 140 being: swung will stretch that the shaft is returned to interu'iediate position as soon-as the lever 146 is released.

T he valve of the spout 49 is also :mtomati-v cally opened and closed when the shelfJS-l and ring 6'? reach their uppermost and lowern' ost positions. The operating means 111-- cludes a vertical'rod 151 slidable in guides.

The link 15% will swing the lever 156 so that the link 15'? swings the arm 158, thereby turning the valve 53 to open position, as seen in Fig. 10. When the slide 'iO reaches its lowermost position, as sen in Fig. 11, it contacts with and depresses the arm 166, thereby sliding the rod 151 downwardly. The link 15 1 will pull down on the lever 156 so that the link 157 swings the arm 158 to close the valve 53.

The operation of the machine is as follows: iissuming that. the sack S has been applied to the ring 67 around the spout 19 with the bottom of the sack resting on the shelf 5 1 with the shelf 5 1 and ring 67 mov ing upwardly, then the valve 53 will be closed by the previous depression of the arm 166 and rod 151 by the slide 70, as seen in Fig. 11. Also, under these circumstances the trip bar 120 is in its real-most position, as seen in Fig. 16, with the gear wheel 101 meshing with the gear wheel 97, so that the screw 6% is rotated in the direction to raise the shelf 5 1 and bag holding ring 67. The lugs 133 of the bar 120 engage in rear of the guides 122, and the bar 120 is in the position opposite to that shown in Figs. 6 and 7, with the bar moved rearwardly to bring the portion 130 adjacent to the shaft 3 and the portion 129 spaced rearwardly from said shaft.

The grain dumped into the hopper 6 from a sack will flow through the openings 12 and 7 into the casing 1 of the mixer, and, at the same time, the powder feeder is operated so as to deliver powder down through the passage 9 to mix with the grain which enters the casing 1. The grain is picked up in the casing 1 by the rotor or wheel 2 to mix the grain and powder and discharge them through the opening a into the lower portion of the elevator housing 5. Too grain is elevated in said housing by the primary elevator and delivered from the buckets 37' onto the lower portion of the secondary elevator whose buckets 4O carry the grain and powder upwardly and discharge same through the housing extension 38 into the chute 4:6. From the chute 16 the grain is delivered into the hopper 4S and has a whirling motion therein, and the grain drops down into the spout 19, being prevented from discharging from said spout by the valve 53 which is closed. When the sack is raised to its uppermost position, the slide 70 contacts with the arm 165 (which occurs as the slide 70 arrives at its uppermost position) thereby raising the rod 151 and swinging the lever 156 so as to turn the arm 158 and shaft 52, thereby opening the valve 53, as seen in Fig. 10. The grain in the spout 49 will therefore drop into the sack,

the bottom of which rests on the shelf 54. At the same time, the shelf 54 being raised rill result in the flange 56 thereof contacting with the arm 150 and swinging the lever 1 16 upwardly, as seen in Fig. 141, so that the rack 1 13 rotates the pinion 142 and shaft 131 clock-wise, as seen in Fig. 1 1. The shaft 131 is therefore turned to move the cams 135 outwardly, and said cams will move the lugs 133 outwardly from in rear of the guides 122. l t the same time, the bar 120 is moved outwardly to bring the portions 129 and 130 thereof into the path of movement of the wiper pin 12S. Said bar 120 being in its rear-most position will result in the pin 123 contacting-with the portion 130 and thereby sliding the bar 120 forwardly, and when said bar reaches its foremost position the lugs 133 engage in front of the guides 122, under the pressure of? the rods 123,

thereby locking the trip bar 120 in its foremost position, and, at the same time, the bar 120 is moved inwardly to remove the por tions 129 and 130 from the path of the pin 128, the bar 120 being now in the position v shown in Fig. 6. The forward movement of the bar 120 swings the lever 112 so as to reverse the connection between the screw 6st and shaft 3, the gear wheel now meshing with the gear wheel 97, seen in Figs. 1 and 15. As a result, the screw 6 1 is now rotated in a direction to move the shelf 5e and bag holding ring 67 downwardly, and the sack is filled by grain dropping down the spout 49 as the sack is lowered. In this way, the grain is delivered into the sack after the sack has been raised, and during the lowering the sack, to prevent the powder passing through the sack as dust.

When the sack reaches the lowermost position, the slide 76 contacts with and depresses the arm 166, thereby moving the slide rod 151 downwardly and closing the valve 53, as seen in Fig. 11. This stops the delivery of grain from the spout into the bag, the bag having been filled. Furthermore, the slide 70 contacting with the roll r 149 will depress the lever 1 16, as seen in Fig. 13, thereby turning the pinion 14-2 and shaft 131 so that the cams 13 1 are moved outwardly, as seen in Fig. 7, to disengage the lugs 133 from in front of the guides 122 and also move the bar 120 outwardly to bring the portion 129 into the path of the pin 128. The pin 128 wiping along the portion 129 will slide the bar 120 rearwardly, and the lugs 133 are moved behind the guides 122 by the spring rods 120. The rearward n'ioven'ient of the bar 120 will reverse the connection between the screw 64 and shaft 3, as hereinbefore described, so that the gear wheel 101 now meshes with the gear wheel 97 to rotate the screw 64 so as to raise the shelf 54. At this point, the filled sack is removed from the shelf 54, and

the machine may be stopped'tor-a slight interval, while removin the tilled sack. An

empty sack is then slipped up on the spout 4-9 and fastened to the ring 67, and the operation is repeated.

One sack of grain is delivered into t hopper 6 for each each that is tilled, and t sack which is emptied into the hopper 6 may be in'imediately applied to the sack holdi ring 67. The mixer and elevator may oper-- ate coi'itinually during: the operation of the machine, 'so that grain delivered con tinually into the hopper 48 and spout 49, it being noted that the valve closes tl spout after a sack has been filled and until the empty bag is brought. to its uppermost position. It is also possible to remove a filled sack of grain and replace same by an empty sack without stopping" the machine. lhe dust resulting from the mini oi? the powder with the grain confined within the casino; 1, housing 5 and hopper i8, and will not escape, thereby protecting the attemh ant. Should the spout 49 become tilled with grain during the time that the valve closed, the grain overflowing from the spout will be held in the hopper a8, and when the valve 53 is opened the grain will drop from the spout 49 into the sack with minimum agitation, the grain moving downwardly as a column from the spout into the sack.
