TYING ATTACHMENT FOR BALING-PRESSES.
SPECIFICATION forming part of Letters Iatent No. 761,305, dated May 31, 1904.
Application iiled June 30,1903. Serial No. 153,790. (Remodel-X To all whom it concern Be it known that I, ROBERT S. JOHNSON, a citizen of the United States, residing at Coleman, in the county of Coleman and State of Texas, have invented a new and useful Tying. Attachment for Baling-Presses, ofwhich the One object of the invention is to-provide a device which may be made and sold as an at tachment and readily applied to baling-presses in ordinary use without the necessity of employing specially-skilled labor.
A further object of the invention is. to pro-.
' vide a device of simple and economicalconstruction in which a pair or a plurality of pairs of jaws are simultaneously forced through the. compression chamber, the jaws constituting each pa r moving, respectively,
. in opposite directions and carrying a binding wire to an intermediate point in thecompress1on-chamber, the wlre bemg afterward twist:
ed together by mechanism actuated after the,
. jaws have reached proper position.
used to introduce the wire to A still further, object of the invention-is't o provide a device of this character in which the wire-carrying aws will at all times be threaded so long as the coil or reel of wire may last, rendering it unnecessary toemploy the auxiliary threading mechanism usually the jaws or carriers after operation. a j
A still further object of the invention is to provide a mechanism of this character which may be conveniently operated by a single workman, rendering it unnecessary to employ any auxiliary power for the purpose.
A-still further object of the invention is 'to provide a novel form of cutting mechanism for severing the wire between two bales, a
ing the knife-carrying jaw -in section.
With these and otherobjects in View, as will hereinafter more fully appear, the invention consists in the novel construction and arrangement of parts'hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of the lI1V6I1'Dl0IL- In the accompanying drawmgs, F1gure 1 is a transverse sectional elevation of a portion of a baling-press provided with a tying attachment constructed in accordance with the invention. Fig. 2 is a'plan view illustrating the arrangement of the operating devices. Fig. 3 is a sectional elevation of a pair of wire carrying and twisting jaws, taken transversely of the baling-chamber. Figs. Land 5 are sectional views, on an enlarged scale, showing the operation of a pair of jaws. Fig. 6 is a detail perspective View of one of the jaws. Fig. 7 is a side elevation of the'cutting-knife, showi Fig.
8 is a diagram showing the arrangement of V the tie-Wires as they would pass around successive bales without cutting the wires. Fig. 9 is a sideelevation. of a portion of the top of the press-box and the actuating mechanism.
Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings. i
I To the opposite sidesof the compressionbox are secured vertically-disposed bars 1 and 2, these being slightly spaced from each" other and provided with aliningj openings, forming guides for the slidable wire-carrying jaws. Inthe present instance two of the jaws are arranged at each side of the compression-chamber for the fOrmati n oft'wowire bales, although any desired number of jaws may be employed in accordance with the size of the bale to be made.
To each side of the compression-chamber is bolted a bracket 3, projecting outward for some distancefrom the side of the box and bifurcatedtd receive aforked arm 4, one end of which is pivotallyconnected by links 5 to a pedal-lever 6, arranged at the top of the compression-box. and within convenient reach of the foot of a workman standing on said box. This system of levers serves to effect the movement of the wire into the compression-chambers, while a spring or springs 7 serve to with-. draw the jaws from the chamber when pressure on the pedal-lever is relieved.
At one side of the compression-chamber are arranged one or more horizontally-guided bars 10, the-outer ends of which are connected to the forked arm 4, and at the inner end of each of these bars is a wire carrying and twisting jaw 11. The extreme inner end of the bar 10 is bifurcated to form a pair of centrally-spaced arms 12, having openings for the reception of the hubs or reduced end portions 13 of a ratchet-wheel 14:, and the extreme end portions of the arms are slit and so arranged as to 1 form flaring forks 15, through which the wire is directed into a groove or recess 16, formed in the ratchet-wheel and its hub members, and
when 'two wires areintroduced into this slot the ratchet-wheel is revolved and twists them together, the ratehet-wheel being held from rotative movement in the opposite direction by means of a small spring-pawl 17. Near the outer ends of each of the bars 10 are arranged two oppositely-directed arms 18 and 19, the
arm 18 being bent for a shortdistance into parallel relation with the main body of the bar, while its extreme outer end is directed outwardly at an angle, and from the end portion to each other, as indicated at 23, in order to permit their ready engagement with the wire leading from the side of thepreceding bale. Under normal conditions the mouth of the slot 16 is in direct alinement with the recesses formed at the ends of the bifurcated portion of the bar 10, and the wire is led from the preceding bale between the forks of arm 19 ver.
and thence through the slot of the ratchetwheel and the eye 21 to the supply coil of reel. At the opposite side of the compression-box the openings in the vertical strips or bars serve to hold the jaw-carrying members 31, each of the same construction and connected to one of the forked arms 4 in order to permit their operation from the pedal-le- At the extreme inner end of the bar are two oppositely-directed arms 32 and' 33, the arm 32 being provided with a wire-receiving eye 34:, through which the wire extendsfrom the reel, while the arm 33 is provided with flaring forked members 35, through which the wire is guided from the corresponding side of the preceding bale, and the relative arrangement of the flaring forked members of the opposite jaws is such that the arm 33 will be received slightly within the forks of arm'19, and thus insure the parts being guided to correct position, while the two sets of forks when brought together form, in effect, a guiding-eye for the two wires. The single wire carried by the arms 32 and 33 extends across between the cye and forked arm in such manner that when the two jaws are moved into engagement with each other the wire will be received within the slotted portion of the ratchet-wheel and when the latter is rotated will be intertwisted with the wire already located within the slot. To operate the ratchet-wheel, there is employed a slidable bar 40, one of said bars being carried by each of the sliding bars 31. The lower surface of the inner ends of bar 40 is provided with a rack, the teeth of which intcrmesh with the teeth of the ratchet-wheel 14: when the bar is moved inward. In order to guide the rack-bar, the bar 31 is provided with aslot 12, with which engages a depending pin 13, carried by the rack-bar, and as a further guiding means the bar 31 is provided with a guide 14 in the form of an inverted U, the'side members of which serve to'prevent lateral play of the rack-bar. The cross-bar of the guide 1 1 carries a swinging block 45, the lower end of which is slightly inclined and normally rests in engagement with the upper surface'of the racl'r-bar, so as to positively prevent upward movement of the rack-bar to an extent sufficient to allow its disengagement from the teeth of the ratchetwheel during the twisting movement, and at the same time this block acts as a frictionpawl to prevent the withdrawal of the rackbar until the latter has been forced inward to a predetermined extent. This inward movement is governed by a notch 48, which when it arrives under the swinging block allows the block to tilt and move out of locking engagement with the rack-bar, so that the latter is free to return to its initial position. In the outer end of the bar 31 is an opening 50 for the reception of one end of a pivoted catch 51, arranged in a slotted portion of the bar 4:0, the upper end of said latch being disposed slightly above the upper surface of said bar 10 to permit the engagement therewith of one arm of a bifurcated lever 52, and when so engaged the upper end of the catch is depressed V and its lower end moved out of locking engagement with the opening 50, so that in ward movement of the rack-bar is allowed after the movement of the aw 30 has ceased; but during the advancing movement of the jaw 30 the rack-bar will be compelled to travel therewith. As an operating means for the rackbars, a shaft 53 is arranged in suitable bearings at one side of the compression-box, and the upper end of said shaft has a cranked handle 5 1 within convenient reach of thc'operator. The levers 52 are rigidly secured to this shaft and have bifurcated outer ends which embrace headed pins or studs 55, carried by the rack-bars.
In operating the device the jaws are normally clear of the compression-chainber, so
" as to permit free operation of the plunger. At the proper time the workman depresses the pedallever and'through the vforked arms 4 and connecting mechanism forces the jaw.
members inward from opposite sides of the compressionrbox until the wirecarried by the Holding the parts in the crank and moves the levers 52 into such position as to disengage the catches 51 from the openings 50. Continuing themoveme'ntof the'crank and shaft the rack-bars are forced inward into engagement with the ratchet-teeth and turn the ratchet-wheel until the two wires held therein are firmly twisted together. The
J pivoted friction-pawl prevents disengagement, of the rackI-bar from the ratchetteeth during the twisting operation and further prevents returnmovement until the twisting operation has been fully accomplished, at which time the'slotted portion of the ratchet-wheel will have regained its normal position, the
' mouth of the slot'being open to permit the escape of the twisted wires. This operation} is carried on-continuously, the wires being introduced from corresponding sides of the formed bales, and as the bales issue'from the press-box they-may be severed by cuttingthei twisted portion of the wires at an interme-i' diate point; but it is preferred to accomplish this cutting operation at the end of the I twisting movement of the ratchet-wheel. The
cutters employed. are each in the form of L-@ shaped "cntte'r'-' bars 60, mounted on pins at one side of the bifurcated portion of the barf 10,and the lower or substantially horizontal arm of bar 60 is provided with a cutting edge adapted to coact with the end of the ratchet wheel hub and the wall of the slot therein td effect the cutting of the wire. The rack-bars are each provided with projecting pins 64,
' which at the completionof the twisting opera-j tion are forcedinto engagement with the ver@ thereby severing the wires;
tical arms of the'L-shaped bars and move the cutting edges thereof'up. and past the slot, I The beginning of the movement of the cutter-bar will of course'occu'r before the completion of the twisting operation; but the actual cutting op eration cannot take .place .until the slot has:-
approximatelyreached itsinitial position.
When the cutteris used, the severed portion I of the twisted wire at the end of the completed bale will readily escape as the forked por-f tions of the arms 19 and-33 separate, while, the remaining portion .in advance of a bale to be formed will escape from the slot and will be held between the. two eyes of the jaw members, and as'the latter are moved outward this twisted portion will remain at about the center of the bale to be formed. When the arms ber"31 In order to prevent wear, the fork or forks may be provided with antifriction-roll sliding through the eyes and one wire being guided to position in the jaw carried by memers 7 O, and said rollers may be curved in order to formguides for the wire.
' In carryingout the invention it is to be understood that the actuating mechanism may press, and for this purpose the pedal-lever is extended rearwardly and in convenient position to be engaged by a pivoted arm 71, mounted in a suitable bracket at the top of the pressbox, the lower end of said arm being adapted to extend within the press-box in position to be engaged by the plunger-head and when so 7 engaged to operate on the pedal-lever and forcethe wire-carrying arms into proper, position in the baling-chamber. This arm 71 is normallyheld in an inoperative position by a spring 72, which may be released whenever it is desired to permit the plunger-head to effect .the desired operation. 1
