leaving a passage-way between them.- Some P This tube is provided with one or.

shaft m, and meshes with a corresponding gear-wheel 32 secured .to the inner end of the shaft g. The loose pulley ll is provided with a clutch 33 by which. it may be clamped tothe shaft g' through the shifting of a slidable clutch member. g. 'A bellfcrank lever 1' 'is pivoted toa suitable support 34 on the frameV a, .thedepending arm of which is' .forked to engagethe clutch member g, and its horizontal arm is extended towards the shaft m. A vertical rod 35 is hinged to' t-he horizontal arm of the bellerank`r, andits :upper end slides in a suitable guide 36 secured tothe building or to the 'framework of Vthe machine. Annrm 37 is 'secured upon the rod 35, and a projecting 'tripper 38 is cari ried upon the crossheadl. Thus, the packer having reached its upper position,'the tripper 38 has raised the ann 37, thereby releasing the clutch y, and stopping the rotation of the auger 'nas well as the further upward travel fof the packing mechanism, and these parts remain idle whileotheroperations-are being performed. i l

'A small platform 39 is plaeeddirectly un# -der the filling tube b to slip ort the bag, and it may -be adjustable for lie-ight, Aor be arranged to raise and lower; but itwill usually -be found more convenient to employ a simple structure, as shown, set low enough for the .bag to clear the tube b when supported upon the platform, since the bag is lirstslipped .overthe tube b, and is pushed doivn almost tothe platform'by the filling tube o. y

. The closing 'mechanismfA hinge shaft 40 is .supported in. suitable bearings upon-one side of the platform 39', and support-sia'swinging frame s comprising the upright-arms'lll and .42 fixed to-said shaft and supporting the respective ends of a rotatable screw-threaded 105 shaft 43. The screw 4.3 has a right handed thread at one end and a lefthanded thread at the' other, 'said thx' ads meeting at its iniddlepoint, as shown 1n Fig. IY, and a spur toothed driving pinion 44 is secured to. one 110 end of. it. A pair of fingers 45 and 46 are screw threaded vand .fitted to ride res ectivcly upon the righ-t and the left hande threads of the screw 43, said fingers projecting inbo'ard, and. being normally .held apart by'ra 115 spring. 47.. 1 A second hinge shaft 48 is s up ported in l'iearings upon the Asideof the platF form -39 opposite to the shaft 40, and is parallel with. the latter.- This shaft supports a swinging frainet comprising upright arms`12o 49and 450 secured to the shaft at their lower by'the horizontal` bars-51 and 52.-

A shaft 'tt tofoperate theclosing and tying means-:isl rotatably supported in bearingsjlg 53V and 54, bein driven by asprocket Wheel .5.5 thereonthrougll achain belt pass'ing over a sprocket. wheel-.57 securedupon the driviuends, and .tied together at theirup'per ends ,lng shaft f.,- Afstep-gear. comprising three packe' segmentalspur`to-othed-gear .wheels 58,-59 'and 13.3

with the shaft in the well known way. -v The clutch member v is operated by a foot-ever 62, which maybe a bell-crank pivoted at' 63 having its upright arm64 forked to engage a circumferential groove inthe clutch member, as shown, and it should have a spring 65 to disengage the clutch when the lever is re-' vleased bythe foot of the operator. lThus, whenthe frames s and tare swung together,

-as in Fig. lf, the mouth of the bag is flattened between the screw 43 and-the bars 51 and 52, and the'ends of the gathering fingers 45 and 46 project'between said bars which serve as guides therefor] The operator may now4 throw the clutch fv into engagement' with the segmental gears, which operates to slide the fingers 45 and46 towardeach other to gather up, the bag. mouth and compress it into. a small space between them, and between the bars` 51 and .52 and the screw 43 whereupon the gathered bag mouth is caught by the `tying mechanism before said 'fingers are released.4 Stops 66 and 67 areprovided to support the respective swinging frames s and t'in ytheir idle -positions which latter. var shown -by dotted lines in Fig. I'.

A The tying mechanism:-'A plate 68 is secured upon the swingingframe t, its outer side being supported by struts 69, and guides 70 are secured upon it between which the tier weis freeto reciprocate. `A shaft 71 is rotatably mounted in bearings 7 2 depending fromfthe plate 68, and carries a spur toothed pinion 73 adapted to mesh with the segmental, gear 60. Another toothed pinion 74 is secured on the shaft 71.which meshes with a toothed rack 7 5 fixed t-o the bottom of the reciprocating tier w. The rack 75 projects through `au opening in the plate 68, which arrangement may also serve to limit the travel of the tier w. The tier w is built upon a' box-like` structure comprising a. lower plate 76, having upturned side flanges, and an upperparallel plate 77 secured' upon said flanges. Referring to Figs. VI, VH, and VIH, it will be seen that the tier plates are, reetangul'arto fit between the guides 70., but have a narrowing forwardf extension which 'is recessed in itsv middle portion at 78.

rotary shuttle is mounted at the inner end Y of said recess, and comprises a spur gear ring having 'its toothed periphery `between the tier plates, its upper face fiush with the top of the plate 77, an approximately V-shaped .y gap 79 leading from its interior to a possible registration with the passage' 78, and a' fixed lugv 80 upon its upper face in the'posltion shown. A clamping dog 81 is pivoted at 82 upon the shuttle a, one end of which is up turned and adapted to be held normally against the lug 8 0 by a spring 83, and its other end is inclined outwardly and faced to` correspond with the curvature of the shuttle;

An upright driving shaft 84 is rotatably mounted in the plates 76 and 77, and has secured upon ,it-a gear wheel 85 between said plates, a toothed pinion 86 just above the upper plate, and a` bevel gear wheel S7'upon its upper end. A horizontal shaft 8S, Fig. IV, is rotatably mounted in a bracket 89 'se-v cured to the' tier w, and carries upon its inboard end a bevel gear 90 in mesh with thev gear 87, and upon its outboard end a spur mediate spur wheels 92 and 93 are rotatably f I mounted between the plates of t-he tier. each being in mesh with both the lwheel S5 and the shuttle so that the latter is driven by one or the other, or by both of said intermediate wheels according to its position.

A thin lever arm 94 is pivoted atv its middle point to the tier plate 77, and its outer and broader end extends underneath the wheel y so asto be engaged in succession by two sets' of pins 95 and 96 carried upon the under side. of said wheel. A tripper arm 97 is pivoted at 98 to the tier plate and provided with a projection on its side toward theshuttle. A connecting bar 99 has its ends hinged respectively to the free ends of the arms 94 and 97, and has a projecting pin 106 to engage the tail of the lever arm 101, which latter is pivoted tothe tier plate and lhas a broadened eXtension curving beyond its pivot and' adapted to engage the dog 811 A light spring 102 in tension between a Ypin on thetier plate and the broad end of the arm 101 serves to keep the latter, vand also the arm 97, normallyout of the line of travel of the clamping dog 81, as plainly shown in 106 is a light spring bearing upon the rearward part of the eye-bar e, and otherlight Its forward end oversprings'may be employed ify found desirable Y to assist theeye-bar to traverse the guide' 105. A crcular groove 107 is formed in the upper face of the cam wheel y, and a substantially triangular cam 108 isset therein, as shown. lever 109 is loosely mounted on the vertical shaft 84, its rearward arm being` bent laterally and provided with a depending'pin 110.adapted to slide in the groove 107, and its forward arm being straight and hinged to the end of a connecting link 111, the other'end'of the latter being hinged to a short arm 112 which is secured to the rota-. table bearing 103l of the eye-bar. A light spring 113, is in tension between'l the forward end of the lever 109 and -a suitablefrigid connecting point at the left of said lever. Thus the eye-bar z'is swung laterally by the cam 108', while at the same time the ends Aof said eye-bar move in a substantially elliptical path'. During the greater portion of the revolution of the cam-wheel 'y the eye-bar z is held'4 stationary in the position shown in Figs. VI. and V II, save-for a few slight vibrationscaused by the pin 110 traversing recessesl 14`made in the outer side ofthe groove 107, the purpose of 'which is to assist'the running'of the twine.'

A steel wire, ,or light shaft 115 isro-tatablymounted'in bearings-116 and 117 upon'the Y tier plate, being disposed substantially at right angles to the normal vposition of the eye-bar e. The inner end of said Wire is bentl in'to a lateralloop 118, and has a hook 119 formed by -a sharp outward bend of its enfl treme end, as plainly shown in Figs. IX and AX. The outer end ofthe hook-shaft .is provided .with a small toothed pinion 120.; in mesh' with rack teeth upon the underside' of a bar 1 21 slidably rnountedin bearings l122- and 123 upon the tier plate. A- spring 124 is disposed in tension to keep the rackbar normally-in its forward position, as shown, but Ia cam 125 upon. the wheel y is adapted to engage a pin 126 upon the rack bartop'ush the latter backward oncev in eachrevolution of said wheel, whichreciprocation of the rack bar accom lishes an approximaterevolution of the hoo r-sh'aft' 115. A' cutter 1.27 having a knife edgeis Yprovided. to cut oil the twine.' Herein I have` shown the 4cutteriiiredfu ontthe end of a bracket 128 secured to t e tier. plate, but this part of my'apparatus I propose to imf prove and make itthe 'subjectof anothelI application. f A

A tension device-is employed con-ipris'ingal stud 129 ,attached preferablyito the eye-bar e at its bearing, an aperture 'through said studlower washer 13 1 upheld by afslioulder on the stud, an'iupper'loose washer 1312, an-adjust-` able nut 133 screw threaded upon theup'per'l end of thestud, and a spring'134- on the lstud y incompression between' the nut and the upf. per'washerf 4 is applied tol the shaft l f whichrotateslthe j;

The swingingarms s and t are in their outer position.

A bag to be filled is slipped yover the'lower end of the'filh'n tube I), and av charge of p ow- .,de'red or granu ar material .suiiicient' to fill the bag is fedinto thesaid tube so that substantially all of it venters the tube o, and is upheld bythe auger n. The operator then vgrasps the lever j and releases the clutch i,

The tripper38 in its. descent strikes the bellcrankl r, thus slidingthe clutch member Q to engage the shaft gwith the pulley 11, and' operating to rotate the auger' n; which auger bores vinto lthe materialabove it, transfers said material to' its underside, and packs itdown into the bag. The clutch t should then be thrownfback" into enthe packer torise slowly Vout of. the bag while the rotating auger feeds the material therein and presses it down. These `n iov'ernents continueuntil the trip'er 38'engagesthe arm 37 and releases the c utchi'ember vq,'xi'vhereupon the packer is withdrawnfintojtheftube-b, the .winged valve on. thejbottom of said "tube is closed, the filling andpacking mechanism is rest awaiting a new. change, and theiilled bag 'stands clear upon :the latform 39, The operator then swings intt erames s andt, and'pre'sses the foot-lever@ to start the closing and tyingInecli'anism.'A .The gathering lingers 45 and 4 6 operatefirst, gathering up and Vclosing the 'mouth of the bag, but, before saidiingers yare, released',:theA tier w has been brought forward,the recess 78 and lgap 79 thereinl forming a passage for the gathered bag mouth which, as' 'the tier'comes to rest., is

consider. that for ordinary packages 'two wraps, as shown in Fig. XH, is su flicient; but

it is-obvious that this is a matter of relative tnn'ing ofthe movements of the respective' parts of the machine.

While the wraps are being made, the eyebar z remains in the position shown in Fig. VH, save for the several slight vibrations for assisting the passage of the cord caused by the recesses 114. has been drawn against the looped wire 118, the cani -10.8 .operates the eye-bai' causing it to describe its elli )tical movement', as indi cated in Fig. VH the twine over-'the ho-l .\119, the shaft- 115 of which then revolwjes, sotliat said loop of which throws a. loop of twine is carried up by the said hook inside the wraps, and out overv theni away from the bag, and, as it is carried over, the knife.127

XH, and the shuttle advances to and stops in' the position shown in Fig. VIH. lItwill be noticed that just before the advancing end of the twine is released by the Al filling tu e and project,througlL-thedower l orifice thereof, a packing.- auger seciired to l the lower end of saidshaft within saldi-nner tube, and a valve for closin the lower orifice 110 clamp S1, and while the hook 119` is iin operation, the eye-bar z is returning i'apic ly to its original position; vwhich movements ni connection with the tension device at 129 oper-' ate to pull the cord taut and tighten theknot before the cord is released andcut off. l`he. foot-lever 62 is now released, and the swinging frames s and t are then thrown back t.o

the position shown by .dotted lines in Fig. l,

which causes the tici to recede by gravity fo its outer posit-ion, whereupon the bag may be removed.

As shown in Fig.'Xll, this apparatus ties 'what is known as a millers knot. or what is sometimes termed a half hitch. This knot is comparatively easily undone by dexterous human fingers, but until thus manipulated it holds fast, because the middle wrap, or wraps, is .pulled tightly across the knot, which prevents the loose ends vof the twine slipping backwarilbeneath the strands of the close drawn -enwi'apment- 'overla )ping wings hinged to the loixy But-,falter the last wrap.
