Application filed March 8, 1906. Serial No. 304,814.

Beit known that I, Aonioinii M. BATES, a citizen of the United States, residing at Cleveland, iii-the county of Cuyahoga and State ot Ohio, have invented a certain new and useful .Improvement in Bagging-Machinos, of whichv the following is a specification.

My invention relates to bagging machines,

land has for its' object to provide new and improved constructions in apparatus of that character. i lThe invention is illustrated in the aC- `coni anving drawings wherein- .i i.. 7

, Figure l isa vertical sectional view, Fig. 2.

Fig-et. a horizontal sec tion on line $-il of Fig. 3; Fig. a diathe exact details of construction shown and described for obvious modifications will occur to any persons skilled ni the art.

.Certain parts or'eertaiii operations inight be omitted and others substituted in their place withoutdepartiiig from the spirit of my invention. For purposes of illus'- tratioii I shall consider the machine as constructed for the purpose of filling suitable valve bags, that is, bags which are to be filled through relatively narrow valved openings, and I shall suppose that these bags are to be filled each. with ninety-five pounds of cement. A

rlhe inachine will be supported on a suiti able base board or flooring A, upon which graininatic illustration of a portion of the circular track; Fig. G, a plan view otone `v.of thebag supporting pans efitlrp'arts in section; Fig. 7, a detail plan of the jiggiiig table: Fig. 8, a section on line S---S of Fig. j

' E which serve as supports for the bags. g Above the hub D isa hub F also keyed to the shaft C and-carrying a ring F lstrengthf ened by 4the webs F2. The/ring F1 has the inwardly sloping` flange F3 which supports i7; Fig. t), a detail view ot' the shut-oit' finger, and Fig. 10, a similar view of one of the opening cams.

' Like letters ot' reference indicateI like parts in all the figures.

The invention relatesI to a niachine for l Each bag inakcs a complete circuit et' the machine. During` this c vcle the bag is 'illed. weighed and lischargcd. l have also pro- `automatically filling and weighing bags In its general? rests-,a standard B having a. eentralbeariiig vblock B1 through which extends the niain shaft C. The shaft C has keyed thereto a worin C1 in a `housing C2 which inay be secured by hangers C3 Cg to the rafters C C1l supporting the flooring A. A worm C on the shaft C5 drivesthe worin Cl. Keyed to the sha-ft C is the hub D which bears upon the block Bl and carries the ring D to which are pivoted a plurality of yokes the cone F". rThe cone F 4 extends into a feeding chamber or hopper' formed by a easing G; This easing l have shown as cylindrical and closed at. the top by a disk it .being the object or' i The bags `are connected with the G1 having a tlange Ggand a central upstanding hub G3 which is mounted in a stationary bearing G* supported by the channel bars G G5, chamber or hopper, which I shall designate generally b v the letter G, through 'a feed pipe GT which yextends into the hub G3.

An internal flange GS on the hub forms a vided means for packing the material in the bag. These operations can bepcrioruicd autoinatieal" through the instrumentaiitv oi" i tion between the stationary feed pipe and the rotating hub G3. This is an iniportant however, tlat l do not desire io he liniiied to l feature when the -niachine is used 'for haii-` the constructions which T have shown and shall describe. l wish it to he understood.

packing chainbtr G which isclosed at the T his prevents the esi-ape ofniaterial at .the poiiit-of connec- The material enters the feed dling such material as cement. A stirring rake G11 is secured to the pipe Gr7 and ex lends down into the throat formed between the cylinder G and the cone. This device serves to prevent the material from clogging. The bags are supported by suitable devices carried by the yokes E. One of these yokes and its associated mrts is shown in Fig. G. The yoke, it will e seen. is pivotcd to a lug D2 on the ring D by means of a pin D. At the outer end of the yoke -is a lug E1 (Fig. l). in which is journaled a roller E1 which travels over a track H. Centrally on the yoke are the knife edges E E ou which is supported the bag holding )an E* which has the u )standing curved back rest E5 partially inc osing the bag.

In Fig. l, the dotted lines J indicate the position of the Bags. The back rest Fi' carries a lug E*s to which is pivoted the link ET connected with one of the webs F2 on the hub F.

The ring F1 has the peripheral recesses F*5 Ff and under these recesses are placed cups or receptaclesK K into which the material is fed from the feeding chamber (i6. The ring F1, it will be understood, closes the feeding chamber G at the bottom except for the apertures formed by the recesses Ff;

The cups K are preferably secured to the under side of the ring F1 by means of screws K' as is shown inthe detail view of Fig. 3. The parts of the cups K extending outside 0f' the feeding chamber are closed by the covers "K2 which set. into a tiange K`J on the side of the cups and are secured thereto by screws K4. Extending from each of the cups K is a filling tube K5 preferably under cut as shown at Ko and having the olf-set K7 at the top. The bags are hung on these tubes, the tubes extending through the filling openings. The bags are preferably held in place by clips L normally held pressed against the tubes by springs L1.

The material is fed from the cup through the filling t'ubes by means of a rotary propeller. I have here shown a two wing curved propeller M located in each of the cups K. The propeller in each case is cured tothe end of an upright shaft M1 which turns in bearings .\l`-, M? ou the cyliuder (l and carries at its upper extremity a pinion M* which engages with a gear wheel'M5 rigidly secured on a driving pulley M mounted upon the hub G3 which may be driven from any desired source of power. bythe belt M1. The shaft M1 passes through an aperture in the cover K2 and this connection between the parts` made dust proof by means oi a packing chamber .\l" formed in a bearing block 'M1'. this packing chamber being closed by the nut .\l 1". In order to prevent any -lubricant Vfrom getting into the cement from the bearings of the shaft M1, a

`The feeding .that the fllmg of the bags will be complete dri u M11 is placed below the bearing M2 and under this, a cup M12. A bushin M15 is preferably inserted around the hub n, The several bearings M 'are formed on a ring M1.

It will bc understood from the foregoing that in the operation of the machine the shaft C will be kept in rotation, carrying with it the elements of the feeding chamber, the separate centrifugal feeders, the bag supports and the bags, the weight of the latter being borne by the rail H. The material may be fed continuously or at intervals into the feed chamber G" and will pass down into the cups K and from there be fed through the filling tubes into the bags. devices will be so organized with one rotation of the central shaft. In order that the weight of the material in the filled bag should be uniform, I have provided certain automatic weighing devices which act in conjunction with the means for shutting otf the feed to the bag when it has been filled to the proper extent. Ihe general arrangement of these devices contemplates shutting ofl' the feed when the bag shall have been filled to within a pound or two of the desired weight', this occurring when the cycle of the particular bag in uestion has been almost completed. The ag, in continuing its circularmovement, will be carried upon a scale and the feeding operation automatically resumed and then shut otf precisely when the desired weight is obtained.

The shut-ott I associatepreferably with the fillingA tube K5. It will be understood that each filling tube is so provided with a. shut-off. It will not be necessary to describe but one of these sets of apparatus.

Referring particularly to Figs. 3 and 4. N is a standard fixed upon the cover Kf1 and to this standard is pivotcd an arm N1 to which is secured a shut-off valve or blade N2, which extends into the front ofthe cup K so as to shut ott the filling tube K5. The arm N1 carries a roller N3 which, in the beginning of the travel of the particular filling a-plniratus. comes into contact with an opening cam secured to the inside of a rail )1 supported from some stationary part of the machine` for example byv he brackets O2. This cam. as shown in Fig. 1 may be in the form of an inclined flangefon/a plate O, the plate being adjustablyfsecured to the ram rail t) by the bolts O" O* which pass through the slot 05. The full line position l of Fig. I shows the arm N1 at the top of this cam with the tilling tube open. The dotted liuc. show the arm in its lower position with the tube closed. Associated with the arm N1 is a latch .tevice adapted to hold thc arm in its upper position. Mounted in bearings N,

X on the standard N isa shatvN6 carrying spring bears upon the arm N1 While the ends a latch NT secured thereto by the pin N8. coil vspring if engages the latch and the standard N. This spring is under tension when the arm N1 is in the dotted position and the latch NT engages saidarm to prevent rotation of the shat't.v lVhen the arm N1' rides over the cam O the lifting of the arm N1 releases the shaft No and the spring will rotate the shaft X so as to bring lthe latch under a-hardcned metal piece NV in the lower side of the arm N1. The arm Will, therefore, be maintainedin its upper position and the filling tube open until the latch shall be tripped, as will next be described. l

Associated with the rail O1 is an adjust able shut-oli` trip, this device being shown `in detail in Fig. 9. It consists of a finger l), which l .prefer to construct in one piece, with the block P2 provided with the clips 1.) iUfwhich make a sliding connection with the rail '01. Secured to the block by rivets P1 Pl is a rod l?4 which ispreferably flexible and passes .tl'iroughl the guide P5 on the rail (i). rl`he end of the rod is provided with a hand grip PU.' The position of the linger may thus be varied at the will of the operator. The finger P stands in the Way of a- `linger 11 onv the shaft N and consequently trips the latch'hT7 so that thej arm N1 is carried down to its' closing position by a V- shaped spring i712. The middle part of this are secured to the ring M1" by the n ts N13 N13.

' The finger P is placed at a point onthe machine at which the bags will have been filled to within a small amount of the` Weight desired. Its position may be varied according to the particular kindv of material being handled. lThen set in one position it will ordinarily not be necessary to reset it ftlhvis"apl'iaratus may comprise any desired tor the same kind of material and While conditions remain substantially unchanged.'

` For example, when the machine is to make packages of ninety-tive pounds, the simboli will be set so as to operate when Vabout ninety-two or ninetyLthree pounds of material have been -fed into the bag. f

i During the travel of the bag around the machine, the yoke E which `carries it will bc supported by the roller, E2 which runs on a track H. This track issupported in any desired manner, as for example, on standards H1 Il? resting on a pile of blocks 'HHZ the number of which may be' varied so as to adjust the rail to the track to different heights according to the size of bags handled. Any other sort of *adjustment might, ot' course, be substituted for this arrangement. After the bag has passed a short distance beyond the trip finger P, the roller ,passes upon a separate track lsection 'H5 `-which is carried, by the Weighing device.

form l'of scale, the parts being preferably ar- 65 ranged so `as to automatically cause the insertion in the bag of an amount of material necessary to make up the desired weight.

In the drawings .I have shown a scale platform R upon which are the adjustable standards H1 H1' similar to those which support the fixed section of the track. R1 represents 'the scale beam suitably supported onl the the platform is of any customary construc` tion." As illustrated in Fig. 1 there is shown one form of usual construction wherein the platform R is connected tothe levers WV and lVl. The lever W supports one side of the platform and is `mounted I upon the part VZ attached to a suitable supporting device.

The other side of the platform is supported by the lever W1 vwhich is supported on a similar device W. The i levers are pivoted together at W4 andthe lever W is connected to. the connectingvrod R11, which in turn is connected to the scale beam R1. i

It Will be seen that When the platform R i is moved down by the proper Weight of material, the rod R1 will be moved down. This movement will lift the scale beam R (see Fig. 2) and since the frame R* is conn'ected thereto beyond itspivotal connect-ion loo to the parts R5, it Willbe seen that this upward movement of the scale beam R1 produces a downward movement of the fra-me R, v

' On the cam Arail O1 aty a place coresponding to the place where the roller o the bag in question passes ontoy the secti n of the track supported by the scale. is anopening cam O, which in its construction and operation is similar to the opening cam O. The roller N will ride over this cam as the bag carrying yoke moves trom the stationary track to the scale and thereupon the shut-,ott

blade or valve N2 will be `Withdrawn' fr'om' the filling tube K5 and the operation' ot' .Filling the bag Will be resumed. Byr this time, itrivill be seen, the .trip finger N11 will have passed under the series of lingers Re.

4l-Vhen the weighton-the scale, duc to the addition of material in the bag, shall have reached the Weight at-r lwhich the scaleV is set, the scale beam R1 g for-Yard end of the fraineR'! will be tilted downward causing the trip linger N to be engaged between tivo of the fin gers R8.' The bag -carrying and filling` vdevice will, of

I'ivill-be raised and the course, be continuing its revolution around the axis of the machine and this motion will turn the trip finger, releasing the arm N2 which will be carried down by the spring N12 to shut oil the feed. The bag will then pass oil the scale, making room for the next bag which has, of course, undergone the process of filling in the same manner. On the cam rail O1 at this point is located a cam which serves to lift up the bag clip L against the tension of its spring L1. This cam S is shown in Fig. 8 as hung from a cam rail O1 by means of a plate S1 adjustably connected with thc cam rail by the bolts S2 S2. The clip L is formed with an oil-set L? which engages and rides over the cam. It will be observed that this cam extends for a considerable' distance, thus raising the clip s0 that the tilled bag may be removed and the new bag put in its place.

I have also shown an automatic device for removing the bags from the filling tubes and discharging them from the machine. This consists of a curved arm T supported on an upright T1 and standing in the path of the bag just after it leaves the scale. The upper part of thc bag comes in contact with this arm and the bag is pushed out of the pan E4. The chute T2 is arranged to receive the bag as it leaves tlie machine. tate the removal of the filled bag from the filling tube the section of track Il3 on the scale is raised somewhat above the stationary part of the track. 'Ihe ends of the stationary track H are, therefore, sloped a tritie as shown at I-I4 H4. Tliis clearly appears in the diagrammatic view of Fig. 5.

In order to insure the proper packing of the material in the bags I provide apparatus for agitating or jigging the bags during the process of tilling. This apparatus is shown in detail in Figs. l, 9., T and 8. It consists of a circular tableformed by three metal rings U U U with spacers U1 U1 between them. The table has a plurality of recesses U? U 2 and in these recesses are mounted on the pins U3 the hubs U* of a number of arms U5 associated with eccentrics UG on the shaft U7 journaled in bearings Us in the central standard B and bearings U9 on the base board or liooring A. Thesel shafts carry on their inner ends beveled pinions U1 meshing with the beveled pinion U11 loose on the shaft C and supported by a collar U12 0n such shaft. One of the shafts UT has a pulley U13 on its outer end, this pulley being driven by the belt U from a source of power not shown. The jigging table as thus described, carries three concentric upstanding rings U15 U15 U15 which may be. strengthened by the metal rings U U U. The pans E4 which hold the bags are provided with three apertures or slots ES Es ES and the npstanding rings of the jigging table To facili-4 machine. In order to adjust the height of the jigging table in accordance with the position of the track H, the pins U3 are l set in slots U1 in the metal rings U.

The use and operation of my device are as follows: It has been supposed, for urposes of illustration, that the machine 1s to )e used for bagging cement in quantitiesof ninety-five pounds. The operator will lit the bag onto the filling tube to the left of the-discharging arm 'I in Fig. 2, the clip L being held up at this point by the cam S. The bag will hang upon the filling tube until the opening cam O is reached., when the valve N2 will be withdrawn and the material forced into the tube by the rotary )ropelle.` M. The tube, it is to be observe is arranged substantially tangential to the circle described by the propeller and as this propeller presents a curved blade to the material it will be apparent that the discharge of the material will be peripheral, that is, 1n a line constituting the axis of the tube. The .propeller will, of course, continue its rotation whether the valve is closed or open, the material being simply driven around in ay circle within the cup K when the valve is down. The filling of the bag will continue until the shut-oil' finger I) is reached. The

. machine will be organized so that an amount of material somewhat less than that which the bag is to ultimately hohl will be fed into the bag by the time it has come within a short distance of the Weighing mechanism. A more exact regulation may be obtained by the adjustment of the finger I on the ram rail. During all this period the bag will have been agitated by the igging tablcf The jigging will now cease and the bag will travel for a more or less short distance until the roller E2 passes onto the rail section sup ported on the scale platform. Just at this point-the second opening cam 0' causes the valve to be withdrawn from the lillin'el tube and the lilling begins again. As soon, nowever, as the required ninety-tive pounds. or any other desired weight, is reached, the frame R* will be tilted, the latch holdingl up the arm N2 automatically tripped, and the feed stopped again. A further revolution of the bag will bring it against the arm 'l` which forces it out of the pan and down the lis-charge chute. TheseY` ste is. it will be t l seen, are all carried out automatically. The movement of the elements of the feeding dw vices is not at any time interrupted, the feed being/merely shut ott' from the bag at the proper times. The Weighing is perfectly accurate since it is accomplished after the material has entered the ha s. The processk of measuring thus provide for may be Asaid to consist lirst of filling a bag with an amount of material aged bythe duration of the operation of to feeding device, and second, a supplementary filling to make up the discrepancy in the amount of material desired'nie'asured by Weight.' IVhen the machine is used-for bagging cement or such .l stationary part which` is .nade to slope up to it atI-IHt. This results in s lackening the bag on the filling tubein order that the Weighing may be accurately done and also to permit the final charge ofmaterial to be inserted into the bag which is presumably almost filled when the bag carrier moves Lonto. the scale.
