BAGGING-MACHINE.

To allcuhom it may concern:

Be it known that I, LORENS C. LORENSON, a citizen of the United States, residing at Hudson, in the county of Columbia and State of New York, have invented a new and useful Bagging-Machine, of which the following is a specification. This invention has reference to bagging machines intended more particularly for bagging coal and coke, and its object is to provide a machine of the weighing type which is, in the most part, automatic and requires but a, minimum amount of attention by an operator. I

The invention comprises a storagebin or hopper from which the coal or coke is fed intermittently into another hopper designed to deliver dlrectly into a bag, the second hopperoperating as an automatic weighing hopper which, when the predetermined amount of material is delivered into the second hopper, will shut off further flow of material thereinto and deliver into the-bag which may be taken as typical of any suitable container but which will be hereinafter simply termed a bag without limitation to such particular container.

The invention includes various mechanisms of simpleand inexpensive but durable construction, which mechanisms are of a character. to be reliable and certain in action. .The invention will be best understood from a consideration of the following de tailed description taken in connection with the accompanying drawingsfforlning part of this specification, with the understanding,

however, that the invention is not confined to any strict conformity withthe showing of the drawings but may be changed and modified so long as such changesand modifications mark'no material departure from the sallent features of the invention as expressed in the appended claims;

umns 1, 2, which maybe made of angle steel 7 or in any other suitable manner and these columns are connected by a cross bar 3 and are strengthened and stiffened by braces 4, 5 and connecting members 6 wherever needed. Secured to and supported by the upper ends of the columns 1 and 2 is a storage hopper 7 provided'at the lower end with'a slanting spout 8 having a downturned extremity 9 for the discharge of the contents of the storage hopper. The spout has a top wall 10 provided with 'an angle portion 11 held against the corresponding wall of the hopper 7 by clamp screws 12 extending through'slots 13 in the angle extension 11 so that the wall 10 may be moved toward or i from the bottom wall of the spout,thereby a changing the effective cross sectional area of the spout for conductingthe material to be delivered through thespout. \Vithin the spout is a gate 14 having a hinge connection 15 with-the bottom of the spout, whereby the gate may be moved into closing relation to the spout with the edge remote from the hinge engaging the adjustabletop 10. The

hinge 15 is exterior to the spout so that when the gate is open it forms a continuation of the bottom of the spout, which bottom is cut away, as indicated at 16,.to permit thengate between the arm 17 an'dlink 20. Fast to the columns 1 and 2 and extending therefrom on,

the side of the columns remote from the spout 8 are fixed supports 22, 23 respectively, and these supports are connected by a cross length, is erected a post 25 constituting a pivot support'for a lever 26 having an arm 1105 beam 24: on which, about midway of its' 27 connected to the link 20 at the end of the latter remote from the arm 17.

Pivoted to the columns 1 and 2 by bolts 28 or otherwise are the legs of a U-frame 29 having a yoke portion 30 underriding the lever 26 and this yoke portion of the U- frame carries a counterweight 31. Hung from the free ends of the legs of the U- frame 29 is a bagging hopper 32, ears 33 fast to the hopper on opposite sides thereof being provided for the purpose. per discharges through the lower end, which is the smaller end, the hopper being conical, and this discharge end is surrounded by a ring 34 fast to the hopper to accommodate the mouth of a bag. The discharge end of the hopper is traversed by oppositely movable gates 35 movable in guides 36 so that the gates may be approached to close the mouth of the hopper or moved away from each other to leave the mouth of the hopper free. Each gate is provided with ears 37 having a pin 38 thereon extending through an elongated slot 39 in one arm of a bell crank lever 40 having a pivot support 41 carried by brackets 42 on the outer face of the hopper 32. The arm 40 is expanded toward the slotted end thereby providing a slanting or angle edge 43.

Carried by the cross bar 3 are spaced brackets 4 forming a pivot support for the yoke portion 45 of a U-shaped rod 46 of which latter the free ends of the legs are so disposed as to move along the slanting edges 43 of the bell crank levers l0 and also to engage the other arms of the bell crank levers, which arms are indicated at 41-7. Rocking movements of the U-rod 46 will cause corresponding rocking movements of the bell cranklevers 4:0 by engaging the arms 40 as the rod 46 is moved in one direction and by engaging the arms l? as the rod is moved in the opposite direction. The axis of rocking of the rod 46 is substantially horizontal so that when the free ends of the rod 16 are raised they engage the arms t? of the bell crank levers 40 and rock these levers in a direction to separate the gates 35. lVhen the rocking movement of the rod 46 is downward, the legs of the U-shaped rod move downwardly along the slanting edges 43 and cause the bell crank levers to rock toward each other in a manner to close the gates 35, thereby shutting off the outflow of any material in the hopper 32.

Pivoted to one of the braces 6 on one side of the main frame is a treadle lever 48, the pivot of the lever being conveniently in the form of a bolt 49 but of course may be otherwise formed. The lever 4L8 is provided at one end with a readily accessible treadle 50 and at the other end is connected by a rising link 51 to a bell crank lever 52 carried by the support 23. The bell crank lever 52 has an angle extremity 53 under- The hopv masses riding one leg of the U-shaped frame 2 Adjacent to the pivot 4-9 011 the side thereof remote from the treadle 50 the lever 48 has fast thereto another link 54 connected to one arm of the U-shaped rod 46.

That portion of the bottom of the hopper 7 leading toward the spout 8 has a screen section 55 for sifting out material sufl iciently fine to pass through it, and in order to avoid undue scattering of such material, the screen section is underridden by a chute 56 directing the screenings into a narrow path and these screenings are prevented from interfering with an operator standing in front of the machine by a shield 57 extending between the columns 'i and 2 and dropping to near the bottom of the device, where a turned out portion 58 serves to direct the screenings away from the operator either onto the ground or floor or into a suitable receptacle. The treadle lever 18 may be held with the treadle lowered either by the foot of the operator or by a latch 59 adjacent to the treadle and in position to be readily disengaged by the foot of the operator. lVhen the parts are in the position shown in Fig. 3, in which case the treadle end of the lever 48 is lowered, the other end of the lever 48 is raised and acts through the link 51 to rock the bell crank lever 52 in a direction to raise the weighted end of the U-frame 29 in opposition to the normal tendency of the counterweight 31. This movement causes the yoke portion 30 of the frame 29 to lift the corresponding end of the lever 26, thus lowering the link 20 and rocking the arm 17 in the direction to close the gate 14 so that any material in the hopper cannot at the time flow through the spout 8. At the same time the lowering of the treadle end of the lever 413 causes a raising of the free ends of the arms of the :"wrme 46, thus bringing these arms into engagement with the arms 47 of the bell crank levers 4:0 and rocking the latter in a direction to open the gates 35. Therefore, the' parts, as shown in Fig. 3, but before the treadle 50 is operated, are in position to have a bag applied to or located beneath the ring 34, and then, on pressing the treadle, coal or coke, or whatever material is in the hopper 32, is released to gravitate into a positioned bag or other receptacle beneath the hopper.

Now, when the hopper 32 has emptied, the release of the treadle end of the lever 48 either by relieving it from the pressure of the foot of the operator or by disengaging the latch 59, if utilized to hold the treadle end of the lever down, permits the counterweight 31 to become active to return the parts to the position shown in Fig. l. The effect of the counterweight is to rock the frame 29 about its pivot supports 28 to raise the hopper 32 close to the mouth of the spout 8 and directly beneath it. The raising of the treadle end of the lever 48 causes a lowering of the U-wire 46 which, moving along the slanting edges 43, of the levers 40, rocks the latter in directions to cause the closing of the gates 35. At the same time, the lever 26 is relieved from the restraining effect of the frame 29, whereupon, the gate 14 opens, both because of its own weight and the weight of the material bearing against it and tending always to open it. Now, the coal or coke has free outflow through the spout 8 and into the hopper 32 until the load is sufficient to overbalance the weight 31, whereupon, the hopper 32 drops to theposition shown in Fig. 3 and then withthe bag properly adjusted under the hopper the operator must, press upon'the treadle 50, thus raising the frame d6 sufficiently to cause the ends of the arms of the frame to engage the arms 47 of the bell crank levers 4L0 and-open the gates of the hopper 32 and discharge the contents of the latter. The dropping of the hopper 32 automatically causes the closing of the gate 14:, thus shutting off further movement of the coal or coke into the hopper 32 until the latter is again raised.
