Application filed July 18,

My invention has for its object to provide an efficient tying machine wherein the bundle wrapping and tying operations will be automatically started upon placing the bundle or object to be wrapped and tied in position in the tying machine. The invention also provides a means for yieldingly pressing the bundle wnile the cord is being drawn to increase the tightness of the cord when the bundle has been wrapped and tied. The invention also has for'its object to provide coordinating parts whereby the improvements that contain the invention may be applied to wrappingand tying machines. The invention also has for its object the accomplishment of other advantages and features which will appear upon examination .of the drawings and from the following description.

The invention may be contained in structures of different forms and to be used for tying cord or twineor the like for connecting parts .or wrapping bundles of different kinds, and thus the structure may be varied to be used for a great variety of purposes and still be within the purview ofthe novelty of my invention. For the purpose of describing and showing a practical application of my invention, I have selected a bundle tier containing the invention as an example of structures that embody the invention and shall describe it hereinafter. The structure selected for purposes of illustration is shown in the accompanying drawings.

trates an, automatic clutch for connecting the tying mechanism with the driving mean of the machine. i

The structure shown in the drawings is of that type of bundle tier machines described and shown in the Patent Number 1,597,696 granted August 31, 1926, to myself and JosephJ. Bachmayer, and contains many of the features describedin the said application. The said application described a machine for forming loops of cord in tags and tying the ends of the loops that are thus formed, while the machine selected illustration and shown in the drawings of this application is for wrapping bundles with cord and tying the ends of the portions of the cord that are used in wrapping the bundles, and particu larly relates to a means for automatically setting the mechanism or parts thereof in operation and for depressing each bundle along the line in which the cord is placed to aid in producing atightly wrapped bundle, together with other features 'more particularly described hereinafter and shown in the drawings, and the coordinating parts whereby the improvements may be properly operated in conjunction with a machine of the type referred to.

The machine is supported on a tripod 1 having an adjustable pedestal 2 for adjusting the height of the machine. It is drivcn by means of a suitable motor such as the electric motor 2 that drives the wheel 3.

located in the casing dthat is suitably sup ported on the pedestal 2. The wheel 3 is located on a shaft 5 and by means of a pinion drives the gear wheel 6. The wheel '6 is freely rotatable on its shaftexceptas it is positively connected thereto by meansof a clutch as hereinafter described. A link 7 is connected to the gear wheel 6 and to an ar1n8 formed of two yieldingly'con'nected parts 9 and '10, and so as to cause oscillatory ,movelnentsof the arm 8 to produce oscillatory movements in ashaft 11 and, if need be, to break the joint between the parts 9 and 10 if the shaft 11 should be stopped by a positive forceand to prevent breaking or of any parts of the machine or iniury to the person operating the machine.

'The'shaft 11 is connected to the needle arm l-Zhaving the needle .13, and consequently the link 7 produces oscillatory movements the-needle to raise the needle well above any package and to draw the cord about the bundle to be wrapped. The cord 14 passes through a suitable guide 15 and a tension device 16 and is threaded through openings formed in bosses 17 on the top of the needle and in the end of the needle. The cord may be drawn from a suitable bobbin or ball 18 that is supported on a shelf 19 forming a part of the frame of the machine. hen the needle is moved down, it places the twine in position to be engaged by the knotting mechanism20 that ties the portions of the cord placed about the package and severs it from that portion of the cord that extends through the openings in the needle and is connected to the bobbin 18, while at the same time the knotting mechanism 2O grips the end of the last named portion of the cord to hold it preparatory to being tied with the portion of the cord that surrounds the succeeding bundle. The cord is severed by means of the combined knife and guide that is operated by the arm 21 that is manipulated by the knotting mechanism 20. The knotting mechanism 20 is driven by the shaft 22. These features are 'described in detail in the said patent referred to above.

The controlling elements for starting the mechanism described and referred to are actuated by the movement of an arm 25 on Which is supported a rack 26. The arm 25 is pivotally connected to the frame of the machine by means of the shaft 27 and is operated by an arm 28 that is also connected to the shaft 27. Thus the arms 25 and 28 form a bell crank lever for lifting the rack 26. The bell crank lever is connected to an arm 29 by means of an adjustable link 30. The arm 29 is connected to a shaft 30 to which a sprocket or chain gear wheel 31 may be releasably connected, as hereinafter described. Rotation of the gear wheel 31 causes rotation of the arm 29 which in turn causes oscillatory moven'ients in the bell crank lever formed by the arms 25 and 28 which operates to raise and lower the rack 26. The gear wheel 31 is driven by means 'of the pinion. 32 which is connected to the shaft 5 which is driven by the wheel 3 that is directly connected to the motor 2 by means of the belt 33. Thus the chain gear wheel 31 is being rotated while the motor 2 is in. operation, but it is connected to the shaft 30 only during these periods that the rack 26 is being ra .fl and lowered.

The movement of the rack 26 is controlled by the weight of the bundle 3*, that is, the

rack 26 is caused to be raised whenthe bundle 35 is placed on the rack. The rack '26 is formed of strips of metal 36 that extend at- Substantially obtuse angles to each other and are secured to an angle bar 87 which is connected to the arm25. The parts 38 of the strips 36 are preferably the arm 44.

slightly curved to lie substantially within the path of movement of the cross bar 37, While the other portions 39 of the strip 36 extend rearwardly from the machine and form a shelf on which the bundle 35 may be conveniently placed. If desired, a finger 40 may be secured to one of the strips 36 to confine the bundle to the corner of the rack and indicate roughly the position at which the cord will be placed when the bundle has been wrapped and tied. It also operates to hold the bundle loosely on the table until it is tied.

The connection of the chain gear wheel 31with the shaft 30 is produced by theoperation of the lever 42, which is pivotally connected to a frame 43 that forms a part of the frame of the machine,it being part of an arm 44 that extends from the machine. The arm also supports the shaft 30 that is located in suitable bearings formed in The lever 42 is connected to a shaft 45 to which is keyed an arm 46. When, therefore, the bundle 35 is placed on the rack26, the arm 46 is raised, the weight of the arm 46 and the parts connected thereto being such as to normally maintain the lever 42 raised, and consequently the arm 46 lowered, that is, before a bundle is placed in position on the rack 26. arm 46 is provided with a spreading block 47 for spreading the jaws of a clutch that is formed of the two clutch members 48 and 49. The member 49 is connected to the chain gear wheel 31, while the member 48 is slip-keyed" to the shaft 30 One of the clutch members 48 and 49 has a lateral cam face such as that shown at 50, while the block 47 also has a coacting cam surface whereby the block 47 will separate the clutch members 48 and 49 so as to discon nect the chain gear wheel 31 from the shaft 30 when the arm 46 is lowered so as to place the block 47 into engaging relation with respect to the cam surface 50, that is, the block 47 resting on the edges of the clutch members 48 and 49 will at one point during the rotation of the shaft 36* engage the cam surface 50 and will wedge or se 1 rate the clutch members 48 and 4. as the shaft 3O continues to rotate the clutch members until the connecting teeth of the clutch members are disengaged. To ieldingly resist this separation of the clutch members and to cause the clutch members to reengage when the block 47 is pulled from beneath the clutch members. a. spring 51 may be located on the shaft 30 and between the clutch member 48 and a ring 52 that is secured to the end of the shaft 30". Thus when the lever 42 is lowered by the weight of the bundle, the block 47 is lifted from between the clutch members 48 and 49 and the spring will establish connection between the continuously rotating chain gear Wheel 31 and the shaft This will; cause-the shaft 30 to rotate and-cause the arm 25-to oscillate, which will raise the rack 26. The lever 42 beingsupportedon the part 43 of the frame of the machine will not move with the rack 26 and consequentlyQas the bundle is raised by the rack 26, it will be lifted fronr the lever' l2. This" will lower-theblock t? in position to engage the cam surface of the clutch'member 48, but owing to the fact thatthe shaft 3O considerable distance before the block 47 will sufiiciently separate'theclutch members 49 to cause disconnection between'the 31 and-the shaft-30 the to an arm that protrudes from the arm 25. Also, in order to yieldingly;disconnect the rack- 26 from the driving chainof mechanical elements that causes the rack to be raised, the arm 28 may be releasably con nected'to theshaft 27, as shown in Fig. 6; A. plate 56 is connected to an arm 57 that is supported'on the shaft 27, 'and'an arm 58 is keyed to the shaft 27 but is connectedto the arm 57 by meansof a latch' 59 that is spring-pressed by the spring 60. One end of the latch 59 is located beneath the spring 60 and extends through an opening formed in the plate.56 andiis provided with a suitable notch 62 that engages the end of the arm 58; The arm 25 is also keyed t0 the shaft 27 and so that if the arm 25 is stopped in its movement by some substantial positive force, the arm 28ibeing moved up ward by the link '30 and the chain gear wheel 31 may continue to move, but the arm 58 will be disconnected therefrom since it will push the latch member 59 to one side against the action of the spring 60 and thus become released from the connection with the arm 28. Thus the arm 28 may continue in its upward movement while the rack 26 will discontinue its movement and will be held by the object or force that is sufficiently great to cause the latch 59 to be tripped and permit the disconnection of the end of the arm 58 from the latch. connection may be easily established, the latch 59 protrudes below the plate 56 as best shown in Fig. 2, and the end portion is bent or cammed away from the shaft 27 so that the arm 58 may be easily snapped" into engaging relation with respect to the latch.

In order that the rack 26 maybe held more positively in its uppermost position than it could be held through the jointed must necessarily rotate a to its uppermost position.

It will then fall of its own weight to the frame 43 exceptas it is resiliently caught by the buffered.

The knotting mechanism is started when the bundle has been placed in position on the-table or rack.- The lever 25, when itis raised to its uppermost position to so place the gear wheel 6 with theshaft 22 to which he lever 65 is connected to a shaft 66 and an arm 67 is connected to'the shaft 66. A cam. block 68 is raised by the arm 67 so as to permit the parts of theclutch 69 to engageshaft 22. The

and cause rotation of the clutch and its operation are the same as that described in the said patent referred to above except that the shaft 66 is actuated-by the arm 25 striking the arm 65 which is connected to the shaft66. j

The table 70 is formed strips 71 that are'connected to cross bars 7 2 that are suitably supported on the frame The ends of the strips 71 bend downward for-receiving the bundle,

which is carried upward by the rack 26, as no at 73. The rear ends of the strips 71 may also be bent downward, as at 7st, for the purpose of delivering the bundles from the 'table into any suitable receptacle, such as a basket or a suitable conveyor. Thus the in succession on the table and the portions of the cord between the l znotting i'nechanism 20 and the raised placed in position on the rack '26.

I have provided means for lever65 that connects mechanism 2-0 is connected."

of a plurality of i along the line that the cord is drawn by the machine, and while the knot is being tied. A presser foot 7 6 is provided which will be lowered when the bundle has been placed in tying position on the table 70. The presser foot 76 is preferably channeled or U-shaped and so as to spread that portion of the cord that extends over the top of the bundle. The presser foot 76 has a considerable length so as to extend across the top of the bundle. ihe resser means may be formed of two or more presser feet that may be connected to a T-shaped bar 77. The T-bar is provided with a plurality of holes 78 in its head that may be tapped, and where a plurality of presser feet Y6 are used the presser feet may be adjustably located at any point along the head of the T-bar 77. The T-bar 77 and consequently the presser feet 76 are located substantially in the same plane that the needle 13 moves in its operations on the cord to draw portions of the cord about the bundle. Thus the cord will be drawn over the bundle beneath the presser feet 7 6 while the presser feet are operated so as to press the top of the bundle while the cord is being drawn by the needle and being tied by the knotting mechanism.

The T-bar 77 is adjustably connected to parallelogram of elements '7 9 consisting of two levers 80 and a slotted frame 81 that forms a supporting head and connects the levers 80 at two of their ends and the member 82 that connects the levers 80 at their remaining ends. The levers 80 are pivotally supported on the part 83 of the frame of the machine and thus substantially vertical. movements are produced in the presser foot 76, while the T-bar 7? is maintained in a vertical position. The member 82 is provided with a centrally located slot 84: and hooked portions 85 located. on each side of the slot. 84:. Rollers 8G ride upon the surface of the member 82 above the hooked portions 85. The rollers 86 are supported on a shaft 87 that i. connected to a pair of springs 88, the lower ends of the springs being positively connected to the lower end of the member 82. The shall; 8'? also extends through the end of an arm 89 that is pivotally connected to the end of the frame. The arm 8!) extends through the slot 84!. formed in the member 82 and so as to receive the shaft. 87. Means is provided for rah i the arm 89 which will operate through the springs 88 to raise the member This lowers the presser feet it; and presses the presser feet a i the top of the bundle, which occurs during the drawing of the cord and the tying thereof. As the bundle may have different heights, the presser feet 76 will strike the top of the bundle at different times according to their different heights, but the arm 89 will continue to be raised by the mechanism although the presser feet by the jointed arm 8 that is connected to the shaft 11. The jointed arm 8 is provided with a cam surface 90, while thearm 89 is provided with a pivoted block 91 that is provided with a cam surface 92 that coaets' with the cam surface to raise the lever 89 when the jointed arm 8 is raised by the operation of the link 7, that is,'the cam surface 90 rolls on the cam surface 92, the two being held in substantially definite relation with respectto each other by means of a link 93 that is connected to thejointed arm 8 and to a nose formed at the end of the cam surface 92 of the block 91. As the arm 8 is raised, the lever 89 is raised and when the presser feet 76 strike the bundle, the continued movement the prcsser feet 76 to the tension of the springs 88, which causes more or less compressing of the bundle while the cord is be ing drawn and tied. To cause the return of the arm 89 when the arm 8 is returned in its oscillatory movements produced by the link 7, a spring 94 is connected to the arm 89 and to the frame of the machine and so as to draw the arm 89 downward, and thus the presserfeet 76 will be raised well above the tops of the bundles and so that succeeding bundles may be placed in the tying position on the table 70.
