ADELME'R M. RATES, OF CHICAGO, ILLINOIS.

MACHINE FOR FILLING BAGS.

SPECIFICATION forming part of Letters Patent N 0. 707,544, dated August 26, 1902.

Application filed January 25, 1901. Serial No. 44,681. (No model.)

To all whom it may concern:

Be it known that I, ADELMER M. BATES, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Machines for Filling Bags, of which the following is a specification.

My invention relates to machines for bagging materials, and particularly to machines for filling valve-bags.

It is illustrated in the accompanying drawings, wherein- Figure 1 is an end elevation. Fig. 2 is a longitudinal sectionon line 2 2, Fig. 1. Fig. 3 is a cross-section on line 3 3, Fig. 2. Fig. 4 is a side elevation of a portion of the machine. Fig. 5 is a detail cross-section of the discharge mechanism on line 5 5, Fig. 4. Fig. 6 is an edge view of the cam-board.

Like parts are indicated by the same letter in all the figures.

A A are the timbers of the frame, consisting of suitable standards, uprights,and crossbars.

B is a pulley driven from the belt 3', adapted to rotate the shaft B which is journaled in the bearing B and is connected by an eccentric B with the spring-pitman B ,which is secured at O to the saddle-like portion,consisting of theinclined boards O O and the lower rocker-like piece 0 resting upon the crossspriug O and preferably attached thereto.

0 C are the hinged bottom supports for the bag, and each is held in position by the latch C on the spring CLwhich is secured to the upper part of the board O. The pitman B finds a guide in the aperture 0 formed by the side O of the receiving hopper or chute. It is ob vious that any other form of guide might be used and also that the pitman could be pivoted to the saddle-like piece. If not pivoted, it imparts a certain swinging or laterally vibratory motion. If pivoted and the parts suitably guided,the motion might be made wholly vertical. It is of course substantially so in the form shown.

C O are the sides on the bottom support C The inclined board C, bottom support O", and sides C form a suitable pocket or supporting part for the bag D. Obviously the rotation of the shaft 13* will impart a rapid vibratory motion to the bottom support, to the bags, and

It serves to keep such bottom support from swinging too far inwardly when the latch is released and also serves as a means for restoring it to the position indicated in Fig. 1. The end of each latch is placed in the line of the excursion of the short lever D which has at its outer end a rod Dflwhich is secured at its lower end to the treadle D The treadle is pivoted at D, and a spring D is associated therewith to restore the treadle to its normal position. On the right-hand side of Fig. 3 the parts are shown in dotted lines in the position which they assume when the treadle is operated and the bottom support permitted to fall down to discharge the bag into the hopper beneath. The bag strikes the hopper side O and falls thence onto the side C and drops free from the bagging-machine. In full lines the parts are shown in the position they assume when by manipulating the strap D the bottom support is lifted up, so

i as to be engaged by the latch. On the opposite side of Fig. 3 the parts are shown in the position they assume while the bag is being filled. The bottom support is preferably, as in the illustrations, in a fixed relation with reference to the driving-shaft; but of course it could be made adjustable along the pitman, the other parts being correspondingly adjustable.

E E are filling tubes or funnels, supplied each with a clamp E, which serves as a topbag support and which is preferably of spring material and tends to gently rest against the end of the tube or funnel, so as to hold the empty bag D in position.

E is a reinforcing-spring attached to the slide E by the metal slat E The slide E projects through the side piece E and is attached to the lever E, which is pivoted at E The attachment is made by means of the bolt E The parts E E E E and E are of course duplicated at each end of the machine, and the side pieces E E furnish the support:

.for the upper bottle-case, which has the bottom F, ends F F, top F The bottle-case contains a series of bottle-like or funnel-like feeding and measuring devices F F The lower end or mouth of each bottle is preferably surrounded by an adjustable rubber ring F and the mouth projects down into a socket in the bottom F, where it may rest against the washer F By adjusting the ring F or by varying the thickness of the washer F an individual adj ustment of the bottle may be obtained, and thus the lack of uniformity in the interior cross-section or the cubic contents of the bottles can be reduced to a minimum. The bottle is open at the top, as indicated at F, where it passes through the top of the bottle-case F By means of the lever E the filling funnels or tubes E, with the slide E can be moved with reference to the bottles F. In their normal position they are in line with each other, so that the contents of the bottle F passes through the tube E into the bag D; but when the slide E is moved a short distance they are thrown out of line with each other, and the slide E serves as a.

valve to prevent the escape of the material from the bottles F During this operation, however, the parts move along the fixed camboard G, which has a series of indentations or cut-away parts G G. These cut-away parts are set in line each with one of the bottles F and are held rigidly in this position. When, therefore, the bags are in position on the filling tubes or funnels E E and such filling tubes or funnels are in line with their associated bottles F, the reinforcing-spring E is opposite one of the cam-surfaces G, and therefore is free to engage the light spring E and cause it to firmly grip and hold the bag against the tube or funnel E. It is quite obvious that this portion of the device could be easily altered without greatly departing from the spirit of my invention.

The particular detail which I have here sought to illustrate is that in which the bag is first lightly held by its upper support and is then subsequently firmly attached in position. In reversing the action the firm attachment is first released and then the bag when filled can pull away from the light support by reason of its weight. The slides E it will be observed by referring to Fig. 2, are so supplied with these funnel-like parts as to provide twice as many such parts as there are bottles. In other words, while one half of the funnels are in line with their respective filling-bottles the other half are disassociated with the filling-bottles. In this position, by reason of the action of the cam-board as described, the bags which are being filled are tightly held by the upper support, whereas the funnels not in use are in a position where the attendant can easily attach the bags to their respective funnels by means of the light attachment or support. When the bags have been filled, the lever E is operated so as to carry the funnels to one side, cutting off the connection between each funnel and the bot tle, and the further operation of the machine brings the unfilled funnels and unfilled bags into position under their respective fillingbottles after the filled bags have been discharged and the bottom-support restored to its normal position. I have spoken of the devices F as bottles. They are preferably of glass and in the form of inverted bottles with the bottoms removed; but they may of course be made of difierent material and of different shapes from those shown.

Some difficultysometimes occurs on account of the tendency of the material being bagged to pack in the supply-Ways. This is true even where long funnels are used or where the tubes are made comparatively the same in cross-section for a long distance. To obviate the tendency to pack, I have provided a series of agitators or stirrers, one for each bottle, for in the form of device here shown it is at the mouth of the bottle where the greatest tendency for the material to pack is found. The particular agitator which I have shown is a piece of wire J, which stands upright in the mouth of the bottle, projecting up into the bottle. It is then bent at J, running across through a groove in the bottom piece F, is then turned up at J and at J is attached to a slide-bar J between the two rows of bottles. This bar is supported in the end plates F F and pivoted at J to the elbow-crank lever .1, which is pivoted at J to the arm J which projects from the cross-piece The elbow-crank lever is provided with a series of adjustment-holes J whereby it is pivoted at J to the rod J which is slotted at J to permit of the adjustable attachment by the bolt J to the arm J on the saddle-like part when attached to the pitman. Obviously the action of the pitman, while it is operating the vibrator or series of devices intended to impart a vibratory motion to the bags, will at the same time, through the mechanism which is described, operate the agitators or stirrers within the bottles to keep the material from packing. The adjustment at J is necessary to disengage the rod J and the arm J when the funnels and their associated bottles are to be vertically adjusted.

The frame-standards A A are slotted at K K at each end of the machine, and bolts K K pass through said slots, whereby the crosspieces E E may be secured at any position along the slots, and with them the funnels, bottles, and bottle-case. This entire collection of parts is intended to be adjustable vertically, the means for moving these parts being associated with the hopper mechanism ries of apertures and adapted each to be moved back and forth in the hopper by means of the lever L which is pivoted at L and attached by the bolt L to such cut-off slide L This slide of course operates as a valve for the several tubes leading out of the hopper. There is one such slide and series of tubes for each series of bottles, with of course in each case and at each end a similar operating mechanism. The hopper is provided with bolts L L, which are associated with the vertical slots L U, so that the hopper and its associated parts can be secured adjustably at varying distances along the vertical line. At each end of the hopper are latches L adapted to engage the eyes L L on the end pieces of the bottle-case.

M is a shaft, there being one at each end of the machine, having each a Windlass M and a metal wheel M associated with the locking-dog M On the shaft is coiled the cable M*, which is secured to the bottom of the hopper. Thus by winding the shaft the hopper may be lowered, if the bolts L are loosened, until the latches L can be put in engagement with the eyes L". It now the bolts K K are loosened, the whole upper por tion of the machine may be lowered along its standards until the funnels are brought to the proper distance from the relatively fixed receptacles or bag-supports. The bolts K K will now be set so as to fix the funnels and bottles in position. The latches L are now freed from their respective eyes, and by re versing the motion of the shafts M the hop per can be raised. This motion will continue until the material contained in the bottle F and the tube L up to its valve is exactly the amount required to fill the receptacle. It is obvious that by raising or lowering the hopper and tubes more or less this amount of material may be varied, or, in other words, there is here an easily-operated measuring device. When the proper point has been reached, the bolts L are set and the parts are then in position to operate so long as the same material is being used and the same receptacles are being filled. There is cornmonly an operator on each side of the machine to operate one set of filling devices. A bag is then attached, being held by the light spring to each alternate funnel, the hopperslides L are moved, and the material flows in and fills the bottle and tube. Then the slides are restored to their normal position and the supply is cut off. The funnels are moved with the slide E into position, so that those holding the bags are underneath the filled bottles, and the heavy spring then forces the lighter spring toward the filling tube or funnel and firmly holds the bag by its upper support. l'Vhile the bags are being filled, a series of bags are being put on the intermediatefunnels. Theslidescontainingthefum nels are then moved in the opposite direction, thus throwing the filled bags and their fillingfunnels out of line with the filling-bottles,

.in somewhat general terms.

cutting off the lower ends of the filling-bottles, and freeing the heavy springs of the upper support. By operating the treadle D the lower support or the hinged portion of the lower or bottom support is freed and the weight of the bag forces the same down. The bag falls out and in falling its contents are sharply forced toward the valve end, thus seating or closing the valve. This is very desirable where valve-bags are used, though many features of my invention and many of its several functions or operations would be equally applicable to bags other than valvebags or, indeed, to receptacles other than bags. This dropping of the bag, however, is particularly important in the case of valvebags.

It will be readily understood that the mechanis'm which I have shown and described can be greatly varied in many important respects and in numerous details without departing from the spirit of my invention, and I wish, therefore, to describe said mechanism and the functions and operation of its several parts mechanism may be, broadly considered, the entire mechanism from the supply, wherever it may be, whether in the hopper or elsewhere, to the bag or receptacle. The measuring device is in a sense a portion of such feedingmechanism. Thevalvearrangement for the admission of the material into the upper measuring-tube and also for retaining the material in the lower measuring tube or part may be arranged in any desired manner. I have shown an arrangement which is quite satisfactorily applicable in the case of a ma chine of the general construction shown. This measuring apparatusis of course entirely applicable to the measurement of any The feeding 1 such materials as those referred to and without regard to the character of the receptacles in which the materials are to be received.

The agitator, which frees the material in the feed mechanism or stirs it at the points in the passage-ways where it would be inclined to pack, may be of any desired form, as, for instance, that of a screw; but I prefer the oscillating wire.

I have spoken of a tube in various places, meaning sometimes thereby to include also the tunnel or the funnel-shaped receiving portion of the measuring device. These several. parts can of course be shaped in the various ways; butIprefer those parts which are round in cross-section and at certain'places funnelshaped, as indicated. 7

The upper support and the lower support of the bag are arranged with means for releasing them, and these means may be simultaneously or separately operated.

I have spoken throughoutthespecification of valve-bags, by which I mean to indicate bags where the space through which the material is admitted is relatively smallthat is,

.bags where the material is not introduced through an opening as large as the cross-section of the bag-and by speaking of introducing the material in a relatively small stream I have reference to the same idea.

Obviously my invention is applicable to numerous bags where the apertures for the in-' I used this term as a convenient term to designate the class of bags which are filled through a comparatively small aperture. On the other hand, many features of my invention are applicable to receptacles other than bags.

The vibration or vibratory action given to the bag or receptacle or its support, as the case may be, or intended to be given to the contents of the bag or receptacle is such a vibration as will produce the result of breaking down the pyramid of material which tends to form within the bag and of filling out the material into the corners or the outer portions of the bag and to fill the upper portion of the bag and freeing the discharge end of the filling-tube from the material. It may be a lateral or vertical vibration or a combination of the two. In the machine shown the direct vibration is vertical; but there is an incidental lateral vibration and the bag in a certain sense dances about on its lower support.

Preferably the vibration is so rapid that the bag is frequently free from its support or, in other words, is tossed in the air. a The platform descends more rapidly than the bag, for its descent is positive, while the bag responds only to the action of gravity and is in a certain degree retarded by its upper support. It therefore is free from its bottom-support, and the bottom-support quickly rising strikes the bag and tosses it upward. The excursions of the bag and its support are of course not very extended, but the action is substantially as described.

When the bags are all full,they can be simultaneously 0r successively freed at bottom and top, whereupon they fall down and the material within them is given a sharp thrust toward the valve to close it. Of course when receptacles other than valve-bags are under treatment this latter action would have to be dispensed with. The arrangement is such that the lower supports are immediately restored to their normal positions. The upper support of the bag, if placed near the discharge end of the supply-tube and if placed where in the process of filling the matter within the bag approaches the lower end of such supporting attachment, it will force the material of the bag down into the material and by reason of the rapid vibration of the nearly-filled bag 7 will speedily punch a hole through the material and ruin the bag. It is to avoid this difficulty that I have placed the bag preferably with one corner up and with the upper sup port above the lower end of the dischargetube, so that this punching action against the material within the bag never takes place. A very small portion of the bag just below'the upper support is left unfilled. This is only necessary where the material of the bag is very flimsy. This small portion of the bag about and below the upper support is left unfilled for two reasons; First, because if it is allowed to fill up the upward and downward motion of the upper support and funnel will destroy the fabric of the bag about the valve. This is true because the bag is made of thin weak material heavily starched, and if there is any downward punching against the mass of material within the bag the starch is broken and the fabric weakened, so that there is danger of leakage about the valve. Second, because .if this space is left slightly unfilled there is room for the material within the bag to move en masse toward the Valve end, and thus better seat the valve. For these reasons the excursion of the vibrator is so relatedto the distance from the end of the feeding-tube to the point where the bag is clamped that when the bag is thus nearly full this unfilled portion will be a small portion about the valve and funnel, and it will have a collapsible or accordion-like movement, so that none of the goods will ever be stretched across a surface of compact salt or material within the bag.

The measuring device is intended to make it easy to determine by measurement, the correct amount of material to supply to fill these bags. It is also desirable to adjust the parts to suit different sizes of bags. For example, if a bag of three pounds is to be filled the distancebetween the lower support and the upper support should be, say, ten inches. With a bag of five pounds it should, perhaps, be twelve or thirteen inches. To secure asuflicient amount of material to fill a three-pound bag, the upper of the two telescopic tubes will be left well down in the lower, while to fill a five-pound bag it would be raised considerably. The parts are set so that the cubic contents of the upper telescopic tube and the lower telescopic tube up to the point to which it will fill will be just sufficient to contain three or five pounds, as the case may be, of material in question.

It will be understood that the filling tubes or funnels are arranged, as it were, in two groups, each group consisting of the alternate funnels or tubes. They could of course be arranged in groups of each third or fourth funnel if under any conditions such arrangement became important. The funnel or tube is a portion of the supply-passage, and the partimmediately above it is of course another portion. For convenience I have referred to this latter part as being a supply-section, so as to describe and claim its operation in connection with the funnels beneath it. The

top support I call a duplex support or group, for it is composed of two parts, one of which has a light grip or clamp action, and the other a strong or heavy grip or clamping action.

The wavy cam, as explained, presents a series of waves, and the lengths from one swell to the other is in this case twice the distance from one filling tube or funnel to the next, so that when one of the heavy clam ping devices is opposed to or in operation with the swell of the cam the other is in the interval between such swells, and thus one set of heavy supporting devices is operated while the other set is thrown out of operation. This result can be accomplished by the motion of the cam or the motion of the funnels.

The devices for tripping the bag-supporting parts, so as to throw the bags out when they are filled at the will of the operator, I would describe under the general term of trip mechanism operable at will.
