BINDING ATTACHMENT FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 496,628, dated May 2, 1893.

Application filed April 20, 1889. Serial No. 308,021- (No model.)

To aZZ whom it may concern:

Be it known that I, ANDREW WIOKEY, of Quincy, in the county of Adams and State of Illinois, have invented certain Improvements in Binding Attachments for Baling-Presses, of which the following is a specification.

This invention has reference to that class of presses in which the material is delivered in rapidly succeeding charges into one end of a trunk or chamber, the charges compressed against the preceding mass, the slowly advancing mass divided at suitable intervals into bales, and these bales delivered in succession in the open end of the trunk.

The invention relates to improved means for automatically binding the bales with wire previous to their delivery. With-the exception of the binding mechanism the press may be in all respects of ordinary construction, and in the drawings I have represented the improvements applied to a press of the type represented in numerous Letters-Patent heretofore granted to me.

The details of the mechanism for feeding the press and for operating the follower or plunger are omitted as they form no part of my invention.

In the accompanying drawings,Figure 1 isa side elevation of the body or trunk of the press with my improvements applied thereto. Fig. 2 is an elevation of the same from the opposite side. Fig. 3 is a cross-section on the line -00 of the preceding figure. Fig. 4 is a perspective view of one of the needles for passing the wire around the bundle to the corresponding twister or fastening device. Fig. 5' is a bottom plan view showing the mechanism for operating the binding devices. Fig. 5 is a plan view showing details of the twister driving gear. Fig. 6 is a horizontal section on the line yy, Figs. 1, 2 and 3. Fig. 7 is a face View of one of the twisters, the adjacent wall of the bale chamber being shown in vertical section. Fig. 8 is an edge view of the same. Fig. 9 is a plan view of a twister and attendant parts, showing the manner in which the ends of the bands are united and the bands severed. Fig. 10 is a vertical section on the line zz, Fig. 8. Fig. 11 is a diagram illustrating the binding operation.

Referring to the drawings,A represents a horizontal trunk or chamber into which the material is delivered at one end through a top-opening at a, and from which the bales are delivered at the opposite open ,end,-a'.

B represents the reciprocating plunger or traverser by which the successive charges are forced forward past the retaining dogs 0, and added to the previously accumulated mass.

The foregoing parts are of ordinary construction.

In applying my improvement I locate close to oneside of the trunk in a vertical line,

two, three or more rotary twisting devices D, adapted, as presently described, to unite the ends of the applied binding wires. At the opposite side of the trunk I mount a corresponding number of horizontally-movable needles E, intended to carry the wires through the trunkfrom sideto side between the ends of the adjacent bales and present them to the action of the twisting devices. Suitable reels or other wire-holders, F, corresponding in number with the twisters are located on one side of the machine, and a like'number of reels or holders, F, are located on the opposite side. The wires are laid from the reels F over the ends of the corresponding needlesand thence through and across the trunk to the corresponding twisters at the opposite side. The wires fromthe reels F, are laid directly to the twisters on the same side of the machine.

In order that the operation of the foregoing parts and the details to follow, may be more fully understood, attention is directed to Figs. 6 and 11, which disclose the general mode of action. The mass of compressed material divided into suitable lengths or bales by intervening boards as usual, progresses through the trunk in the direction indicated by the arrow. When the line of separation between two bales arrives opposite a needle the latter advances through the trunk and passes the wire between the bales in a double or looped form to the twister at the opposite side as shown in Fig. 6, the course of the wire being also indicated on the extremeright in Fig. 11. When the wire thus passed between the bales reaches the twister the latter operates and unites the wire which has just entered from the opposite side with the wire entering on the side where the twister is located, thus uniting the two wires as shown, at the middle, in Fig. 11. The cutter then actsto sever the twisted portion at the middle of the twist, leaving the forward bale completely surrounded by the two wires as shown on the left hand in Fig. 11, the one wire extending as shown, around three sides of the bale, and being connected at its extremities by the shorter wire extending along the fourth side. The binding operation being completed and the applied bands severed,the mass advances step by step the length of one bale, causing the remaining or unsevered wires to be eX- tended lengthwise of the second bale, after which the needle advances as before, carrying the one wire between the bales to its companion on the under side, that the twister may again complete the binding action.

Each twister consists of a beveled pinion, D, supported by a horizontal journal, d, in a rigid bearing, (P. The bearing, the journal and the pinion are slotted in an axial direction from one sideinward to the center, or, in other words, slotted radially, as shown in Figs. 7 and 10, the slots being of a width equal to the diameter of the-wire so that when two wires are laid side by side therein, and the pinion rotated, the effect will be to twist the wires together above and below the pinion, as shown in Fig. 9. -In order that the pinions may grasp the wires and direct them into the slots with certainty, I provide them with hooklike arms, d extending outward and forward from the rear wall of the slot, which arms, passing through the notched ends of the needles, pick up the wires carried forward by the latter and carry them up over the rounded bearings (1 The wires so picked up, being under tension, enter the radial notches in the pinions D, and when they reach the openings in the bearings d they drop down into the hub d, upon the wires passing at the opposite side of the trunk, which are already in said hubs. The grooves in the hubs being only wide enough to admit a single wire it follows that by the rotation of the twist-er the two wires therein are wound or twisted together at both ends of the hubs, as represented in Fig. 9. The wires passing along the side of the trunk on which the twisters are located pass on the outside from the spools to the openings opposite the twisters and then pass through said openings to the inside, as represented in Fig. 6. Thus, when the wires are severed after being twisted together the succeeding bale, as it is formed and advanced, draws the connected wires forward. As the bight of the wire is carried outward by the rotation of the arm 61 it rides against the open rounded side of the bearing 01 shown in Figs. 8 and 9,which acts to open or spread the bight or looped end of the wire in a vertical direction so that it will ride over the bearing and pinion and enter the slot therein.

The severance of the wire after the completion of the twisting operation may be effected by a knife of any suitable construction, but I recommend, as shown in Figs. 3

and 9, knives d pivoted at d to fixed supports, and arranged to move closely over the face of the respective pinions so that the united wires are severed between the two twists, leaving the two wires which constitute each band united.

Referring now to the needles for passing the wires across the ends of the bales and presenting them to the twisters, attention is directed to Figs. 3 and 4:, in which it will be observed that the inner end of the needle is notched vertically and also slotted horizontally to admit a peripherally-toothed wheel, 6, mounted to turn on a vertical pivot therein. The wheel having the notched teeth to sustain and carry the wire serves all the purposes of an ordinary anti-frictiondevice or sheave, allowing the wire to pay smoothly and easily around the end of the needle, while at the same time, the space between the teeth being exposed by the notch in the end of the needle admits of the hook on the twister passing in between the teeth and behind the wire so as to grasp the same with certainty.

For the purpose of driving the twisters, the needles and the knives, I mount on the under side of the frame or trunk in any suitable guides, a longitudinally-reciprocating frame H, which I denominate the rackframe. This frame is provided with an operating pitman, 71, adapted to be connected to the plunger or traverser at will, so that it' may be carried to and fro thereby as hereinafter described in detail.

The rack-frame is provided on one side with a rack-bar h engaging a semi-circular pinion, 773, on one end of a vertical shaft, 71. in fixed bearings. This shaft carries at its upper end a crank-arm, 72/ and the pinion 71. is pro' vided with'a corresponding crank-pin. The crank-arm and crank-pin are connected, as shown in Fig. 3, by the pitman h, to opposite ends of an upright bar, 71. to which the outer ends of all the needles E, are attached so that as the rack-frame is moved to and fro it causes the needles to be thrust through the trunk or bale chamber and retracted.

The twisters receive motion in the manner following: A second rack, 71 on the rack-frame engages a pinion, h, on the lower end of a vertical shaft, h mounted in a fixed bearing. The shaft, h is provided on the lower end with a fly-wheel and is connected by a beveled gear with a pinion, It, on the bottom twister.-

The pinion h instead of being fixed on the shaft h is mounted. loosely thereon, and provided, as shown in Figs. 3 and 5, with a pawl 71, which engages a ratchet wheel, h, on the shaft. The arrangement is such that the pinion is permitted to turn while the twister remains at rest during the outward or backward movement of the plunger and rack-frame. The bottom twister in turn communicates m0- tion through beveled pinions h it, and their connecting shaft 71, to the middle twister. The middle twister in turn communicates mo tion in like manner through gears h h, to

eeaeas 'top and bottom, as shown in Fig. 3. In order to secure a proper action it is found advisable to have the angles or corners formed by the junction of the horizontal and vertical walls filled out or rounded. To avoid the great expense of rolling the main sheets into suitable form for this purpose I have adopted filling pieces a ,which are inserted between the horizontal plates and the flanges on the vertical plates, the inner edges of these pieces which are exposed within the trunk being rounded so as to fill the angle as shown in the drawings.

The operation ofthe series of knives is effected by a vertical gravitating bar, d, to which they are all pivoted at their tail ends, the bar being provided'at its lower end as shown in Figs.- 3 and 5, with a roller d? which is acted upon and raised at the proper time by an inclined arm or cam, (:1 projecting rigidly from the reciprocating rack-frame. It will thus be understoodfrom the foregoing description that the twisters begin to rotate with the forward movement of the needles, and that the first rotation carries thewire on that side over the bearing and into the slot in the twister, the latter merely revolving around the wire without twisting it. Assoon, however, as the wire carried'forward by the needles from the opposite side comes within reach of the arm d", it is picked up and carried over and caused to enter the twister, as already explained, and this occurs at the instant that the rack-bar and needles reach the limit of their forward movement and when the action of the pawl and ratchet mechanism h 71. also ceases. It is evident that without some provision for continuing, the

rotation of shaft h, the twisters would also stop before twisting the wires together. Hence I place a fiy-Wheel h on the shaft 71 the momentum of which revolves the shaft and twisters a sufficient number of times to form the twists after the driving force ceases to act.

The plunger or traverser is required to reciprocate rapidly and constantlywhile the.

binding devices are to be brought into action only at comparatively long intervals. It is for this reason that the connection between the plunger and rack-frame is placed under the control of the operator as before mentioned. The most simple and preferred arrangement to this end is that represented in Figs. 1 and 2, in which it will be observed that the pitman h, is provided at one end with a vertical stud, h, to enter an arm on the plunger from the lower side. A lever, h mounted on theframe lies at one end beneath the pitman which slides longitudinally thereon. The opposite end of the lever is-controlled by a vertical rod h mounted in guides on the main-frame and under the control of the attendant. When this rod is depressed so that the lever will raise the pitman the stud on the latter will engage with the plunger and cause the rack-frame and plunger to move together, but when the lever is released it permits the pitman to fall out of engagement so that the rack-frame and the entire binding mechanism connected therewith'may remain at rest until a sufficient quantity of material has accumulated to form another bale. duced between the lower end of the rod and the lever to prevent excessive pressure being applied through the lever to the pitman, but this is not a necessary feature.

The detaining dogs 0 are subjected toa severe lateral pressure by the reaction of the hay against them,and as ordinarily mounted it is found that they are liable tobind and fail to move in the proper manner. To overcome this difficulty I adopt the construction shown inFig. 6. Each dog is in the form of a horizontal bolt having one end beveled and projected inward through the wall of the trunk. At the outer end it slides through a stationary guide and at the inner end it is'connected by a vertical pivot, 0 to one end of a horizontal link, 0 which is in turn connected by a vertical pivot to a frame. This gives the bolta strong lateral support but avoids side friction thereon and permits it to move endwise in a smooth and easy manner. A spiral spring, 0, applied around the upperend of the dog urges it constantly inward. At the inner end each dog is formed with an open horizontal slot, as shown in Fig. 3. The binding wires are laid through these slot-s which serve to guide them and also to prevent them from getting into such position as to be pinched or cut by the ends of the plunger.

The operation of the binding apparatus is as follows: During the accumulation of the bale the pitman his out of connection and the binding devices remain at rest. When the proper time arrives for the binding of the bale the operator, depressing the rod, h

against thelever it, causes the lever h, to lift the pitman into engagement with the plunger whereupon a rack-frame is moved to and fro and caused to operate the binding devices. During the retreat of the plunger from the compressed material the needles are thrust. through the trunk so as to present the wires across the end of the completed bale to the twister at the opposite side. During this action the twisters owing to the existence of the ratchet mechanism in the driving train, remain at rest, but the instant that the plunger starts forward again the twisters revolve and unite the wires, after which they are severed.

A spiral spring, 71 is commonly intro- Owing to the fact that the needle operating pitmen, h, stand practically upon the center the needles remain at rest or practically so momentarily and until the twisters have grasped the wires presented by them. The entire binding operation is performed by a single forward and backward movement of the plunger, after which the binder driving pitman is again disengaged. The fly-wheel on the lower end of the pinion driving shaft serves to continue the motion of the twisters after the action of the driving-frame ceases, wherebythe wires are the more firmly united.

Having thus described my invention, what I claim is- 1. In a baling-press, the trunk and plunger, in combination with the reciprocating rackframe connected with, and operated by the plunger, the crank-shaft geared with the rackframe, the transverse binding needles, and pitmen connecting the same with the crankshaft, whereby the reciprocations of the rackframe rotate the crank-shaft and operate the needles, the twisters also geared with, and driven by, the rack-frame, and cutters adjacent to the twisters for severing the Wires.

2: In a baling-press, the combination with the trunk and plunger, of the reciprocating rack-frame connected with, and operated by, the plunger, the crank-shaft geared with the rack-frame, the reciprocating needles, and pitman connections between the cranks and needles, whereby the latter are reciprocated, the twisters also geared with the rack-frame, the cutting devices adjacent to the twisters,

and a cam-arm on the rack-frame for operat ing the cutters.

3. In combination with the trunk and plunger, the reciprocating rack-frame detachably connected with, and operated by, the plunger, the crank-shaft driven by the rack-frame, transversely moving reciprocating needles coupled to the cranks of the shaft, the twisters geared with, and operated by the rackframe, and means for disconnecting the rackframe from the plunger and again connecting the same.

4. In a baling-press, a needle notched across its end and slotted in a plane at right angles to the notch, a toothed wheel pivoted or journaled in the slot, the ends of the teeth being notched for the reception of the binding wires, in combination with a rotary twister having an arm adapted to pass through the notch ot' the needle and between the teeth of the wheel therein, to take up the binding wire, substantially as shown and described.

5. In combination with a slotted twister wheel substantially as shown, a binding needle, provided at its end with the wheel having the teeth with notched ends to present the wire to the twister.

In testimony whereof I hereunto set my hand, this 9th day of April, 1889, in the presence of two attesting witnesses.
