BAGGING-MACHINE,

Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed May 16, 1906. Serial No. 317,069.

To (LIZ whom it may concerns,

Be it known that ADELMER M. BATES, a citizen of=the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Bagging-Machines, of which the following is a specifica- My invention relates to machines for tilling receptacles, particularly receptacles having relativelyv small lilling openings, for example, valve bags or the. like.

The invention makes a practical application of the well known physical principle that a stream of material acted upon by gravity tends to become attenuated in the course of the fall of the material.

The invention contemplates, among other things, causing the 'material to be fed throughan opening of a size sufiicient to practically prevent the clogging of the material, but at such a distance above the relatively vcontracted opening of the receptacle that it will feed freely into t-he receptacle without hindrance.

The invention has for its object also certain new and improved means for holding the receptacle, for agitating the same so as to pack the material therein, and for .releasing it when thetilling process has'been completed.

The invention is illustrated in the accompanvingdrawings, wherein-- l Figure 1 is a front elevation of the ma-l chine with parts in section; Fig. 2, a View on line 2 2 of Fig, 1'; Fig. 3, a vertical sec-. tion on line 3-3 of Fig. 1; Fig. 4, a detail of the clamping cam; Fig. 5,\avvertical section on line 5 5 of Fig. 1; Fig. 6, asection on line 6-6 of Fig. 2 g'Fig. 7, a plan View 0f the bag carrier, and Fig. 8, a plan View of the agitating device.

Like letters of reference indicate like ,I have shown and shall particularly describe my invention as applied to a machine@ for lling bags, but it will be evident that.-

dled without material variation. y The machine which l have shown consists of ay battery of several bag filling devices whichmay be operated together. The

-beams B4 by the bolts .C1 C1.

apparatusis mounted upon a base-plate A.

Above this plate are supported a plurality Y of feed hoppers B, B, B, B. These are shown as distinctA receptacles, although that will not be essential under all conditions,

these several hoppers being designed'to yfeed This struct-ure is supported from the lbase plate by the uprightslB3 B3.' Securedbetween the beams B4 Bt which form parts of the bottom of the hoppers on each side are the hollow castings C. There will be one of these castings for each of the hoppers, but it will be suiiicientl to refer to anddescribe a single hopper'and itsassociated parts as it is intended that feeding devices connected with each of the hoppers should .be the same.

The casting C is shown as bolted to-the This casting is formed with 'the central .throat C2 'and with the extended vertiealange C3.' This casting forms `the stationary sect-ion oftheK filling tube which is designed to be extensible.` The, lower movable section of the filling tube consists of a casting D extend; ing over the-end 'of the casting C and tapering so as to have a relatively contracted outlet or throat D1 at the lower end. To the end of the casting-D is secured the spout D2 which is preferablycut ott obliquely for convenience vin inserting' into the filling opening ofI the bag. Thelower end ofthe casting D is split andprovided with a pair of lugs D3 through which passes the -bolt D4 anda pair of downwardly extending lugs D5 between which is pivoted at E the' vhandle E1 of the -bag clampmg cam E2.

This cam is preferably provided with the upturned ratchet teeth E3. The full line position, Fig. 3,l shows the cam E clamping the bag against the spout D2". yThe d/ot'ted -cxtendedl set screws F1 F1 and passing loosely through the upper lugs F2 F2 and the lower lugs F3 F3 on the casting D. Springs F4 F4 are interposed between the lugs F2 and the collars F5 F? fixed on the rods F. Buffers F Ff' will preferably be placed at the upper end of the rods.

y'It will be seen that the bag is clamped to the filling tube. This will perhaps not be necessary under all circumstances. but it is my preferred arrangement. I also prefer to support the bag from the bottom. This maynot be necessary under all conditions, but itis very desirable, particularly when the bags are of considerable size or when they are to lbefilled up completely. I have shown all of thel bags which the machine is designed to fill as supported on a single carrying structure suitably made so as to provide a separate support for each of the bags. This carrier is shown in plan in Fig. 7 and in elevation in Figs. '2, 5 and 6. It consists ofa bowed or convexed 'frame Work designed to give a saddle back support for the bags, thereby insuring the complete filling of the corners. I have shown this structure as comprising a pair of channel irons G G connected by suitable bolts G1 G1 to the angle iron supports G2v G2 bearing upon the driving shaft H. The channel irons are connected by the curved castings G3. Upon these channel irons and upon these castings are the longitudinal beams or `strips G4 G4 preferably of Wood and bolted to the iron Work by the bolts GF i5. the elevation ofthe carrying structure one or more shines Go may be interposed bet-Ween the channel irons Gr and the supports G2. The .carrying struct-ure is shown as tilted back as in this particular form of machine the bag is intended to be filled through an opening in thecorner as shown. The carriervvill rest uponthe end blocks G7 G7.

I also prefer to provide the machine with a back restfor the bags. differ considerably in girth it is desirable to have this Asupport adjustable. I have shown the support as consisting of the lower lbox or frame Work J secured to the carrier by the straps J", J2 and of an upper adjustable structure consisting of a back board K, end pieces K1 K1 and dividing partitions K2 K2, the parts being preferably braced by the beam or strip K3. The upper or adjustable section is provided with doWel pins K which may be set into perforations K K in the lower section so as to give the former any desired position. Straps K on the In order to vary As the bags may lower section are arranged to overlap the upper sect-ion.'

My machine also has means for agitating the bags during the process of filling so as to insure the proper packing of material. Preferably this agitating means operates directly on the bottoms of the bags through the slots or apertures in the carrier. This jigging or agitating device is shown in plan in Fig. 8. It consists of a frame work designed to be reciprocated by 'eccentric mechanism connected with the driving shaft and having upstanding members which intermittently strike the bottoms of the bags. This structure consists of two beams L Lfastened `together at the ends by the bolts L1 L1. The upstanding members or jiggers are secured to these beams by the bolts L2 L2 and preferably consist of pairs of uprights L3 L3 which may be of Wood, over Which is the metal sheathing L4. Blocks If secured at each end to the jigging device between the beams L are provided with apertures L6 through which extend the guiding pins LT of the agitating device will be drawn in and out of the slots in the carrier frame, the Whole jigging structure playing up and down on the guide rods L7.

I Wish it to be understood that I do not desire to'be limited to the exact details of construct-ion shown anddescribed for obvious modifications will occur to any person skilled in the art. In a machineof this character 'precise arrangements and constructions are necessarily dependent to a large extent upon the size,-character and number of the receptacles which the apparatus is calculated to handle.

I havefchosen one form of bagging device for the purpose of illustrating the various features of my invention, some of Which may, of course, be omitted under some circumstances and for others, substitutions may be made, according to the exigencias of the particular case.

The use andl operation of my machine are as follows: The bag Will be first. clamped upon the filling tube and a charge of material Will then be deposited in the appropriate hopper. v This may betdone automatically or by hand. I have not shown any particular means for filling the hoppers, as that forms no part of the invention in question. The material, by force of grayity, will begin feeding down through the throat C2 in the bottom of the hopper.l T his throat is made large enough so that there is no danger of clogging. It will ordinarily have to be considerably 'larger than the filling opening of the bag. The stream of material passing through the throat C will. therefore, have to be considerably diminished or attenuated before it reaches the filling opening of the bag and this I prefer to accomplish by placing the bag at a sufiicient distance below the throat C2 so that the stream of material will pass through the saine without hindrance. This method of gravity feeding has marked advantages for certain kinds of material over the method fore, that the distance of fall of the mate-4 rial between the throats C and D1 increases during the process of filling. The stream become more attenuated `as the filling progresses. Thus, if at first there is any tendency to clog at the mouth of the bag; this tendency is automatically ov-ercome as the filling goes on. l

I prefer to support the bag at the bottom and also at the back and sides. -It will,

therefore, be evident that some difficulty might arise in separating the filling t-ube and the bag when the filling has'been accomplished. This difficulty is, however, obviated by the` structure of my filling tube. The operator merely grasps the handle E1 and throws it down to the dotted line position of Fig. 3, releasing the teeth E3 from the material of the bag. The spring F* will immediately retract the filling tube,

drawing the spout out. of the mouth of 'the bag. The operator may still keep his hold on the handle, thus guiding the filling tube back to its collapsed position so as to prevent jar of the apparatus. Then the handle has been pulled up to set the ca'm, it will lbe seen that the weighty added to the bag by the incoming material tends to tighten the grip of the teeth Egon the bag. During this time, it will be understood, the bag has been subjected to agitation by the jigging device. The position of the bag on the .saddle back support insures the packing of the material into the corners. The jiggers, it will be seen, operate directly upon the bottom of the bag. At the same time the bag rests upon a stationary support 'so that it is not subjected to any severe strain as might be the case if it ha'd no other support than the clamp at the upper end.

I claim:
