GRAlN-BAGGlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,121, dated September 20, 1898. Application filed May 8, 1897. Serial No. 635,650. (No model.)

To ctZZ whom it may concern.-

Be it known that we, JAMES W. HENRY and ALEXANDER GUNN, of Wallace, in the county of Shoshone and State of Idaho,have invented a new and Improved Grain-Bagging Machine, of which the following is a full, clear, and exact description.

The object of the invention is to providea new and improved grain-bagging machine arranged to properly support and hold open an empty bag or sack during the filling operation, to close the open end of the bag by sewing after the bag is filled with the grain, and to finally discharge the filled and closed bag from the machine.

The invention consists of such parts and combinations as will be fully described hereinafter and then defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Fig. 15 is an enlarged side elevation of the needle with parts in section. Fig. 16 is a side elevation of the tension device for the thread in the needle; and Figs. 17, 18, 19-, and 20 are sectional views similar to the left-hand portion of Fig. 7, the views showing the parts in various positions to illustrate the operation thereof.

Theimproved machine is mounted on asuitably-constructed frame formed with a base A, posts or columns A, and a top plate A in which and the said base- A is secured a vertically-disposed shaft B, on which is mounted to turn the bag-carrier C,provided at its lower end with a table 0, resting on a collar B, attached to the shaft '13. The bag-carrier is also provided with a top resting on the collar B secured to the shaft B, and the said top is connected with the table O by adjustable standards, each formed of two pieces C 0 fitted to slide one on the other and adapted to be secured together by bolts 0 after the desired distance is obtained between the table G and the top 0 It is understood that when an adjustment is made to increase or diminish the distance between the table 0 and the top 0 the standards are adjusted and the table 0 is moved up or down with the collar B adjusted accordingly on the shaft B. This arrangement isnecessary for different-sized bags to be filled with grain, the said bags resting with their lower ends on the table 0 and the upper ends or the mouths of the bags being engaged by bag-holders, as hereinafter more fully described.

The bag-carrier O is rotated by mechanism driven from the main driving-shaft D, journaled in suitable bearings on the top plate A ator, andon the said shaft is also secured an eccentric E, connected by its eccentric-rod E with a block E fitted to slide in a suitable casin g A attached rigidly to the main frame.

In the block E is formed an openingE into which extends one end of a bellrcrank lever E fulcrumed in an opening formed in a second block 6, also sliding in the casing A The block F. is formed with a recess 6 in its I oo upper side, into which projects a pin 6 fixed in the block c. The blocks 6 and 6 therefore have independent sliding movement limited by the slot e and pin 6 The bellcrank is provided with a tooth E adapted to engage the notches 0 formed on the peripheral edge of the top C of the bag-carrier O, as shown in Figs. 7and 17 to 20. The rod E, being reciprocated by the eccentric E, drives the block E rapidly back and forth in the casin g A The block 6, being also slidable in the casing A and carrying the bellcrank E is moved with the block E As the block E moves leftward from the position shown in Figs. 7 and 17, it moves independently of the block e until the pin 6 is engaged with the right-hand end of the recess e. WVhen this takes place, the bell-crank 1ever 6 will have been thrown to engage its joint F. with one of the notches G of the top 0 of the table. Then when the block e begins to run with the block E the bell-crank lever itself will be advanced leftward and the top 0 will be driven. Fig. 18 shows the position of theparts immediately before the block (2 begins to move. Fig. 19 shows the two blocks 6 and F. moved leftward after having advanced the top 0 and Fig. 20 shows the parts in the position which they assume when the block E has been partly recovered and immediately before the recover of the block e begins. The casing A is provided with a spring-pressed pawl E, which engages the notches C of the top (3 to prevent retrograde movement of said top.

The top C of the bag-carrier O is out out at four places to form openings, in which are arranged four ba -holders F, each formed with a fixed segmental jaw F, integral with the top 0 and the two movable segmental jaws F and F pivotally connected at their ends to the top 0 and pivotally connected at their inner or free ends with a radial bar G, fitted to slide in suitable bearings C formed or attached to the top 0 The pivotal connection between the bar G and the movable jaws F and F is by means of a pin in the bar G, the said pin passing through elongated slots in the free ends of the jaws F and F so that on moving the bar G radially inward or outward the jaws F and F are opened or moved into a closed position, as illustrated in Fig. 1.

Each of the bars G is provided near its outer end with a depending lug G, carrying a radially-extending rod G fitted to slide with its inner end in a bearing formed on the under side of the top C (See Fig. 2.) On this rod G is coiled a spring G resting with one end against the aforesaid bearing and with its other end abutting on the lug G. The spring G serves to move the bar G into an outermost position, so as to hold the movable jaws F and F normallyin a closed position, as indicated at the left and right in Fig. 1. The lug G of each bar G is also connected with one end of a chain G passing around pulleys G and G, journaled on the top 0 the chain extending downwardly from the pulley G to connect with a vertically-disposed arm G fitted to slide vertically in suitable bearings attached to the standard parts C previously mentioned, each arm G being provided at its lower end with a foot-piece G adapted to be engaged by the foot of the operator to press the foot-piece downward to impart a sliding motion to the arm G in the same direction, so as to exert a pull on the chain G to pull the corresponding bar G inwardly, so as to open the movable jaws F and F as indicated at the front and rear in Fig. 1. When the front holder F has its jaws F and F in an open position, as shown in Fig. 1, then the bagis attachedwith its mouth to the said jaws by means of fixed pins F held on the movable jaws F and F and by pins F forming part of the fixed jaw F, but laterally movable thereon, as hereinafter more fully described.

When the bag has been placed in position on the holder, the operator releases the pressure on the foot-piece G to permit the spring G to push the bar G, with its holder, downward to close the jaws. When the carrier G is now rotated or given a quarter-turn, the closed jaws move into the position shown to the left in Fig. 1. A friction-roller G on top of the bar G now moves in engagement with a cam G fixed to the under side of the top plate A of the main frame, and when a quarter-turn is now given to the carrier 0 this friction-roller G in traveling along the fixed cam G causes the bar G to slide inward, so as to bring the jaws F and F of this holder into an open position at the time the holder moves into a rearmost or filling position, as indicated in Fig. 1. The bag is now filled, and when this has been done another quarterturn is given to the bag-holder C, so that the friction-roller G passes off the cam G to permit the spring G to act on the bar G and close the jaws F F so as to hold the mouth of the bag over the grain contained in the bag during the time the bag is closed by sewing, while the bag passes from the fourth position back to the first position at the front of the machine.

Each of the fixed jaws F forms an integral part in the form of an upwardly-extending segmental flange of the ring C of the top C of the bag-carrier, as plainly indicated in Figs. 2 and 5. The pins F extend parallel one to the other and pass through openings in the jaw F, and the set of pins for each jaw are attached at their inner ends to segmental blocks F fitted to slide on top of the ring C in the rear of the jaw F. 011 the top of each block F are formed angular recesses F each engaged by a pin H, depending from a seg ment I'I, fitted to slide on the top of the ring (3 and held in place thereon by bolts 1-1 passing through segmental slots H formed in the segment H. On the under side of each seg ment H is formed a recess H (see Figs. 5 and 6,) engaged-by the wrist-pin of a crank-arm H formed or secured on the upper end of.

the shaft H arranged vertically and mounted to turn in suitable bearings in the ring G On the lower end of the shaft H is secured a handle H adapted to be taken hold of by the operator to impart a turning motion to the shaft H so as to cause the crank-arm H to impart a sliding motion to the segment H, so as to shift the block F inwardly or outwardly, according to the motion given to the handle H The block F by moving outwardly pushes the pins F a suitable distance beyond the inner face of the fixed jaw F, so as to securely engage the web or fabric of the mouth of the bag to securely hold the mouth of the bag in an open position when the jaws F and F move inward, carrying along the inner part of the web or fabric of the mouth of the bag to hold the mouth open during the filling operation. When the block F moves outwardly, the points of the pins F are partly withdrawn in the fixed jaw F, and when this takes place the bag is in a filled position at the front of the machine, and the withdrawing of the pins disengages the fabric of the bag, so as to release the closed-up mouth to allow the removal of the bag from the table C. Each of the pins F is preferably provided on top with a transverse notch F to retain the fabric of the bag in place as long as the pins are in an outermost position and during the time thebag is being filled.

The device for sewing up the mouth of the bag while the latter passes from the fourth to the first position is arranged as follows, special reference being had to Figs. 8 to 14.

On the end of the shaft D is'secured a wheel I, formed on its inner face with radial grooves I and I engaging blocks 1 and 1, respec tively, extending with their outer endsinto openings J and J respectively, formed in the segmental needle J. The blocks 1 and I are provided near their inner ends with pins 1 and I", engaging the cam-groove K of a disk K, provided with a hub K rigidly supported on the main frame and through which passes loosely the forward end of the shaft D. In the disk K is formed an annular race K for the segmental needle J to travel in, the latter being carried around by the,blocks I and 1 as the shaft D is rotated, the said blocks being carried around by the wheel 1, before mentioned. In the under side of the disk K is formed a transversely-extendin g recess K through which passes the doubled-up edge of the mouth of the bag, the said edge extending above the closed jaws F F F as the latter pass from the third to the fourth position and from the'fourth position back to the first position, as will be readily understood by reference to Fig. 1. Now during the time the needle J passes through the doubled-up edge of the bag the corresponding block I or- I is moved inwardly by the action of the pin I or I traveling in the cam-groove K, the latter being shaped so as to move the corresponding block into an innermost position at the time the block passes over the recess K Thus both blocks are always in engagement with the needle J for pushing the same around in the race K except when one of the blocks 1 I is drawn inwardly to pass the recess K". The forward end of the needle J is provided with a point J and the rear end thereof is made hollow and provided with a hinged plate J held in an open position by a spring J but adapted to be opened to place the coil of thread L in position in the hollow part of the needle, as shown in Fig. 15.

The sewing-thread is doubled up and formed into a coil with the doubled-up middle portion extending lengthwise through the coil and with the outer loop L adapted to hook upon the hook K of the plate K fulcrumed on the ring K at the side of the recess K. The doubled-up ends of the coil of thread L pass through a tension device N, fitted into the outer end of the hollow portion of the needle to give the desired tension to the thread passed through the fabric material of the bag. The tension device is formed with two longitudinally-extending elliptic springs N N having their convex sides inward toward each other, as shown in Fig. 16.

Now when the several parts are in the position, as shownin Fig. 15, and the needle iscaused to travel in the raceK then the needle passes through the bag material and the loop L of the sewing-thread at the hook- K and as the cord is now drawn tightlythe loop slips off the hook K and locks the first stitch on the bag. The cord or thread is carried through the bag material within the needle and over it, so as to form a succession of overstitches. The coils or spools of threads L are so formed that the thread is unwound from the forward end and. drawn through the center of the coil,

the outer coil being the last to unwind. 1 The adapted to form back-rests for the sides of the bags. The upper end of each board 0 is con nccted by a short chain 0 with the corresponding chain G so that when the treadle or foot-piece G is pressedby the operator and the corresponding jaws are opened then a pull is exerted by the chain G on the chain 0 to tilt the upper end of the dumping-board O inward and the lower endvoutward to throw the filled and closed bag off the table 0, as shown by dotted line at the left of Fig. 2. The chain 0 is somewhat slack to permit the jaws to open before the board commences to throw the bag off.

The operation is as follows: When the several parts are in position, as illustrated in Fig. 1, the jaws F and F at the front of the machine are opened by the operator pressing the corresponding foot-piece G A bag is now placed on the pins F and F after which the operator removes his foot from the footpiece G to permit the corresponding spring G to close the jaws F and F, as previously explained, so that the two sides of the mouth of the bag are pressed against each other or clamped between the fixed jaw F and the movable jaws F F The operator now shifts the belt from the loose to the fast pulley D, so that the shaft D is rotated, and a rotary motion is now given to the bag-carrier C by the mechanism above described to move the bag from the first to the second position, so as to bring the friction-roller G in engagement with the cam G In the second quarter-revolution of the bag-carrier the jaws F F are opened, so as to hold the mouth of the bag open at the time it passes to the third or rearmost position, and while in this position the bag is filled with the grain, it being understood that the belt is shifted from the fast to the loose pulley after each quarter-revolu tion of the bag-carrier has been made, so as to give sufficient time for filling the bag. During the next quarter-revol ution-that is, after the bag has been filled-the movable jaws F F close by the action of the spring G at the time the friction-roller G passes off the cam G so that the mouth of the bag is closed when the bag arrives at the fourth position. The projecting edge of the mouth of the bag above the jaws now passes into the recess A and during the first quarter-revolution the needle J is caused to travel around in its circular race K to sew the edges of the mouth of the bag, as previously explained. Then the bag finally arrives at its first position, its

mouth is sewed up, and the operator now turns the handle H so as to withdraw the pins Fiand then presses the foot-piece G so as to open the movable jaws F and F As the movable jaws F and F swing inward their teeth F move out of themeshes of the jaws of the fabric of the bag, and as the pins F have been withdrawn they are also out of engagement with the fabric, and consequently the mouth of the bag is wholly free from the jaws, and at this time the dumping-board 0 turns, as before explained, so as to throw the bag 01f the table 0. Another empty bag is now inserted in the jaws and hung on the pins F F, after which the operator releases the foot-piece G to permit the jaws to close, as before explained.
