This invention relates to automatic machines for tying cord or other relatively limp binding materials about any desired work, although par ticular utility is to be found in the tying of compressible substances such as sausages, bologna and other food products encased in readily deformable covers. An important object oi the invention is to provide an improved tying machine capable of quickly tying and pulling taut upon desired work a modified bow or slip knot which, when completed, eiects a very secure tie yet may be quickly and easily released.
Another important object is the provision of improved tying apparatus which is of particular utility in repeatedly tying a plurality of such knots in succession, as in automatically tying into link form an elongated sausage casing fed into the machine, and whereby compressible material such as encased sausage may, by the automatic tightening of the knot, be constricted to form the usual divisions between the links of sausage and the like. u
Other objects and advantages will be apparent from the following description wherein reference .i is made to the accompanying drawings illustrating a preferred embodiment of my invention and wherein similar' reference numerals designate similar parts throughout the several views.

Figures 13 to 17 inclusive are diagrammatic Views successively showing positions assumed by the tying elements and the cord in positions they occupy during the tying of a knot, indicating the manner in which the tie is effected; and
Figures 18 and 19 are sectional and elevational views respectively of the tied knot, before and after it is pulled taut.
Referring now to the drawings, reference character 2| designates the bed of my improved machine, shown as comprising a relatively heavy horizontal plate carried on legs 22. Suspended beneath the bed is a driving motor 25, which, through worm 25 and worm wheel 2l, drives the countershaft 30, hung beneath the frame in bear# ing brackets 32-33 (Fig. 3). Worm wheel 2l is secured to the sleeve 3Q, which is integral with the clutch drum 35. The unit comprising the sleeve 34 of the drum 35 is mounted for free rotation on the shaft 39. A notched disc 36 is freely journaled on the sleeve 35i between the gear and drum, While a helical torsion spring 35st encircles the drum and isk fastened at one end to the disc and at the other end to a collar 3l secured to the shaft. The spring Vmay be some- Whatbiased to contract, and arranged so that the frictional drag of the drum upon the spring tends to expand the spring when the disc is held. When the notched disc is released, as by depressing the foot pedal 45, the biasing of the spring and/or the inertia of the disc tend to wrap the spring about the drum, the engagement of the spring and drum being tightened by cumulativeincrease of friction between the spring and the drum as the latter picks up the drive and turns'the shaft through the spring and collar. When rotation ofthe disc is halted, the turning moment at the collar end of the spring expands it to free the drum and interrupt the drive, again allowing free rotation of the gear and drum. If, as shown, a single notch is provided in disk 3S, (see Fig. 2) the operating parts will always stop in the same position, and the gearing, cams and mechanism are preferably so proportioned that one complete tying operation and advancement of the work to the extent of one link take place during one revolution of the countershaft, which Fast upon one end of shaft 30 is a gear 41, the y web of which also serves as a face cam, carrying upon its outer surface a lobe 48 which when the gear is rotated intermittently reciprocates the follower 50. The follower, slidable in a bracket 52 also hung from the under side of the frame, engages a bellcrank 53 which abuts the bottom of and transmits the intermittent motion to a rod 55 vertically slidable in the bed and carrying at its upper extremity a pawl 51 engageable with the teeth of a ratchet wheel 59. The ratchet wheel is rotatable with and serves to actuate the work drum 60, carried therewith on a shaft 62 trunnioned in bearing supports 63, which bearings may be uncapped and the drum held in place only by gravity, in order to enable its easy removal. It will be seen that by virtue of this arrangement the drum may be intermittently rotated in a clockwise direction, as viewed in Figure 3. The drum serves to intermittently actuate the continuous sausage casing 65 shown as comprising the work, along which at spaced points the machine ties tightly constricting binding material defining the links of the sausage, the rest periods being coordinated with the tying mechanism presently to be described and. the tying of course being effected during such periods of rest, while the degree of each intermittent rotation of the drum determines the lengths of the individual sausages. The rope or chain of sausage may simply be wrapped once or twice about the drum to enable the latter to exert tractive effort thereupon, and thereafter may debouch into a receptacle (unshown) or to any other destination. The tractive eifort of the drum pulls the sausage chain through a tube 61 carried above the bed of the machine in the main brackets 1 -12.
The tying mechanism includes a reciprocating needle 10, and a shuttle 15. whose tapered nose portiongis both rotatable and reciprocable into and out of intertted engagement with the needle. Sliding movements of the needle and shuttle are effected and controlled by a plate cam 11 mounted between the brackets |50-12 to rotate on an axis concentric with the Work tube 61, on the tubular shaft encircling the work tube and driven from countershaft 30 by gear 41, meshing with an idler 19 which in turn drives the tubular cam shaft through gear 80 mounted thereon outside the bracket 12. Idler gear 19 is rotatable upon a stub shaft formed by a shouldered cap screw 8| carried by the bracket.
Grooved tracks 83-86 are formed in opposite faces of the plate cam 11, the former engaged by a follower 81 carried by an arm 89 extending be hind the cam and connected to a slide 90 reciprocable across the opposite face thereof toward and from the work, which is exposed by a break I 65 in the work tube, the slide element being carried upon slide bars 9 |-92 extending transversely of the work tube axis above and below the same, and supported from the bed by brackets 94-95. Slide 90 carries the needle 10, which is reciprocable relatively to the slide in brackets 96-91 shown as cast integrally with the slide, movement of the needle therethrough in one direction being limited by the stop 98, while spring 99 allows yieldable movement of the needle with respect to the slide in the opposite direction. The resistance of the spring is adjustable by means of lock nuts |0| threaded on the end of the needle and the spring is trapped between the lock nuts and bracket 91. A guide screw |02 carried by bracket 91 may also slidably extend into a slot |03 formed in the needle, to hold the latter against turning. The nature and extent of the sliding movement of the needle will be explained later in conjunction with the description of the machine.
A somewhat similar slide |00 also carried by the slide bars ill-92 upon the kopposite side of the work tube and likewise reciprocable toward and away from the work, carries the shuttle which is formed integrally with a shuttle tube 16, forming a continuation of the shuttle, both being hollow, and the shuttle and tube being mounted for rotation in, but held against longitudinal movement with respect to the slide |00, the tube 16 being secure-d in and extending through a collar |04 journaled in the slide |00 as in antifriction bearing |05. The follower |01 by which slide |09 is reciprocated engages track 86. Such follower is not directly carried by the slide, but by a yoke |09, through which it may impart a yieldable drive to the slide, to which it is connected through springs I0 mounted between col,- lars xed to rods H3, and brackets 2 carried by the slide member |00. lThe rods 3 are slidable in the brackets and secured to the yoke |99 soV that a yieldable drive from the latter may be transmitted through the springs. Further constructional details of the shuttle, and the purpose and extent of its movement, will be set forth in detail later in connection with the explanation of the operation of these parts.
Rotation of the shuttle is effected through gears |5-I I6, the former mounted on and drivable with the cam shaft 18, and the latter carried by an inclined shaft I8 extending there from to a point adjacent the end of the shuttle tube remote from the work tube, and supported in supplementary brackets |9| |2 carried by the bracket 12 and bed 2| respectively. The shaft ||8 carries at its lower end a mutilated bevel gear |22 through which intermittent drive is imparted to the bevel gear |23 carried upon stub shaft |25 which transmits the drive to helical gears |26, |21, the latter keyed upon a hollow shaft rotatably mounted in anti-friction bearings |3|, |32 carried by' bracket 95 and in extension |20 thereof. 16 is slidably keyed in and extends through the hollow shaft |30. The central bore in the shuttle tube is designated |33, and allows passage of the tying cord therethrough, which is supplied from a cop |31 mounted'beneath the open end of the tube on a bracket |42 projecting from the frame. Carried by the shuttle tube and movable into and out of the hollow shaft |30 by sliding movement of the former, is a gripping device |3B, |39 carried in a cut out portion |35 of the shuttle tube. The gripping device is formed of hinged jaw sections |38, |39 which as the shuttle is retracted from the work by rearward movement of the shuttle tube grip the cord to cause continued retracting movement to exert a pull thereupon.l The jaws are pivotally mounted in the transverse slot |36 extending through the tube 16, which slot intersects the central bore |33, as upon a cross pin |40. The jaws are tapered at their ends facing the tubular shaft |30, and so proportioned that when slid intov the hollow shaft by rearward movement of the shuttle tube, they are thereby forced together so closely as to tightly grip the cord |35, Where- 'Ihe shuttle tube as at other times, the jaws not being forced together, the cord is freely slidable between them.
The cor-d passes through the shuttle tube to' and out of the shuttle, for engagement with additional cord handling means. Such means are carried partly by a xed standard |50 mounted upon the bed between brackets 1 |-12 and assisting in the support of the rods ill- 92, and partly by a plate |5| rotatable concentrically about the work tube upon the other side of the standard |66 from cam 11 and arranged upon a hollow shaft |53 rotatable in and extending through bracket 1| and drivable by gear |54 mounted on the shaft on the opposite side of the bracket, the gear being drivable from countershaft 38 by countershaft gear |55 and idler |56.
Plate |5| carries a cord gripping and cutting device including a plunger |51 slidable therethrough and extending into a slotted head |58 projecting from the plate upon its side facing the standard |58. The slot |59 in the head is tapered, as best shown in Figures 10 and 11, and at one side of one end a sharpened projection |68 adapted to serve as a cutter is provided. The bottom of the slot terminates in a partly cylindrical transverse opening, while the plunger |51 is provided with conformingly shaped slotted openings, whereby when the plunger is reciprocated in the head, one end of a cord extending through the slot is cut off, while the other end is gripped between the plunger and head. The cutter head assembly of course travels in a planetary orbit when the plate is rotated. Such orbit lies approximately in the plane of the break |65 in the work tube which exposes a short length of the sausage casing or other work, between a standard |56 and plate |5|. The plunger |51 is urged toward retracted position by a spring |62 acting upon the plunger within a housing provided by an enlarged opening in the plate and by a continuation thereof formed by a bracket |61 carried by the rear face of the plate, through which the plunger |51 extends,
carrying upon its rear extremity a follower roller |64 actuable by a face cam |66. The cam |66 is carried by the plate |5|, being mounted lfor planetary rotation and to revolve about its own axis upon a post |68 eccentrically carried by the plate in such position that follower |64 lies upon the circular track of the cam. Rotation of the cam about its own axis is effected by a fixe-d gear |18 secured to bracket 1| concentrically surrounding the work tube and shaft |53, upon which gear rolls an idler |12 meshing therewith and with the gear |14 mounted to turn as a unit with and drive the cam |66 and carried by the plate |5| upon another post |13.
The side of the shuttle facing the plate |5| is cut away as at |15, and its tapered nose is slotted as at |16 to provide connection between its end and the cut out portion |15. It will also be seen upon inspection of Figure 1 that when the shuttle is in its inwardly projected position, the orbit of the head |58 carries it through the cut out portion of the shuttle, in which cut out portion the cord extending through the Shuttle is exposed. In threading the machine the cord is carried through the cut out portion of the shuttle and out the rear wall thereof through an opening |11, and its end is placed in and gripped by the head |58, which maintains its hold upon the end of the cord during a greater part of a single orbital revolution of the head.
At the commencement of the cycle of operations involved in the tying and tightening of a knot, the operating parts occupy the positions shown in Figure 13, the shuttle 15 and needle 18 being retracted with respect to the work 65. The rotation of plate |5| carries the head |58 in a clockwise direction as the parts are considered in diagrammatic Figures 13 to 17 inclusive. The shuttle together with its tube moves forward with the rotation of member |58 until the shuttle reaches a position shown in Figure 14, where it dwells for a certain interval. TheV gripping device |38|36 being freed by the advancement of the shuttle tube, continued rotation of the head |58 pulls the cord from the shuttle, and it is caught by and wrapped about the spring fingers |86, |85 mounted on the plate |5|, and spaced outwardly from the work. 'Ihe tension upon the cord subsequently pulls it 01T the hooks and it is drawn in against the work as the gripping head approaches'the position shown in Figure 15. As the head travels from the positions Yindicated successively at A and B in Figure 14 to the position indicated in Figure l5, the shuttle is rotated to wrap the cord about the end (by the toothed portion of mutilated gear |22). The needle then enters the shuttle. Its hooked end engages beneath the portion of the cord stretched between head |58 and the work, and the needle is then retracted, as indicated in Figure 16, forming a simple bight which it pulls through the loop constituted by the portion of the cord wrapped about the nose of the shuttle, the cord portions extending to the head |58 and to the Work traveling through the slot |16 and pulling free of the shuttle with the loops, as the shuttle is retracted, in the manner indicated in Figure 17.` The retraction of the shuttle closes the gripping device |38, so that continued retraction pulls upon the end of the cord running through the shuttle Yto the supply, to tighten the noose, while the continued retraction of the needle pulls upon the bight which extends through the loops, tightening the part drawn about and constricting the sausage.
It will be seen that the bight is freed of the shuttle, except for the portion running through opening |11, to the supply, by the retraction of the shuttle and by the holding effect of the cord portions which extend from the slot |16. During the entire period thus far described cam |66 has held plunger |51 in projected position, the head |58 having traveled more than 360 degrees, but at this phase, after the knot has been tightened suiiiciently, cam |66 allows plunger |51 to recede under the inuence of spring |62, freeing the end of the cord. Thereafter, as indicated at C in dotted lines in Figure 1'1 the head |58, continuing its travel, strikes the loop held by the needle, disengaging the cord therefrom, thereafter traveling freely until it engages the portion of the cord stretched between the shuttle opening |11 and the work, which it catches in the slot |58. Cam |66 then projects plunger |51, severing the end of the cord connected to the work and gripping the end extending from the shuttle, which end it thus picks up to carry around the work in the commencement of another cycle, which repeats in the same fashion, the parts at this time having reassumed their Figure 13 positions and the phases recurring as described. The cam in order to effect desired operation of plunger |51 makes one revolution in two complete turns of the disc |5| and head |58, and the other parts are of course proportioned and timed to impart in their indicated and proper sequence the movements described in conjunction with the foregoing description of the operation of the machine.
