TYING-M ASE-ENE.

To all whom it may concern:

Be it known that I, LINDLEY CLARK, a citizen of the United States, and a resident of Greenfield, county of Hancock, and State of Indiana, have invented a certain useful Tying-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.

The object of this invention is to provide a simple and effective device for economical and easy tying mechanically of small packages, suchas bundles of letters, newspapers and small boxes and the like.

The machine has been invented with particular reference to use in post-ofiices for tying mechanically bundles of letters, but itmay be used for other purposes, as above mentioned.

The general features of the knotting mechanism and some of the associated parts are substantially the same as that heretofore in use in twine binders and other tying machines.

An important new feature of the invention is the use of a rectangular needle bar adapted to reciprocate overathe package.

Another feature of the invention consists in severing the cord or twine and stripping it off from the knotter instead of the machine discharging the bundle as in binders and tying machines heretofore. Small packages of letters cannot be mechanically discharged without injury to the same.

The nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a side elevation of the machine showing a package being tied and with the normal position of the needle bar indicated by dotted lines. Fig. 2 is a side elevation of a portion of the breast plate from the line 22 of Fig. 1,

portions of the breast plate beingbroken away. Fig. 3 is a section on the line 33 of Fig. 2. Fig. 4 is a plan View of the twine receptacle. Fig. 5 is a front elevation, or an elevation of the left-hand side of the machine as it appears in Fig. 1. Fig. 6 is a horizontal section on the line 6-6 of Fig. 5. Fig. 7 is avertical section on. the line 7-7 of Fig. 6. Fig. 8 is a vertical section on the line 88 of Fig. 1, parts being broken.away Fig. 9 is a plan View of the machine. Fig.

1, the other parts of the machine being omitted, and showing the pos tion of the parts preceding tying the knot Fig. 11 is a vertical section on the line l111-of Fig. 10. Fig. 12 is the same as'the upper part of Fig. 11, showing the parts in adifi'erentstage of the operation. Fig. 13'is asection on the line 13-13 of Fig. 9, but on a larger scale. Fig. 1 1 shows the same as Fig. 13 in a diiferent stage of the operation and with positions of the guide shown by dotted lines. Fig. 15 is a section on the line l5l5 of Fig. 13. Fig. 16 is a side elevation of part of the mechanism shown in Fig. 14. F1 17 is a lILOI'lZOIXtZLl section on the line 1 '-17 of ig. 1. i

In detail there is shown herein a skeleton frame 10 with a table 11 forming the upper part thereof upon which the package 12 which is to be tied is placed by hand as hereafter explained. The twine 13 is shown held in the twine receptacle 14 having a hole centrally located in the top and a flat spring 15 is secured to the top of the twine receptacle, see Fig. 4, for frictionally engaging the twine so as to resist slightly the outward pull on the twine. The twine passes about a pulley 16 on the lower end of the needle bar 17. Said needle bar 17 is rectangular, having a long vertical portion which is vertically reciprocable through a guide 18 secured uponthe table'll. There is also a horizontally extending portion of the needle bar 17 and a front downwardly extending end which carries a needle 20. The twine passes from the little roller 16 over a little pulley 21 on the upper left-hand corner of the needle bar, as shown in Fig. 1, and another little pulley 22 at the upper right-hand corner of the needle bar, and

package to be tied is moved by hand later-- I ally against the slackened portion of the twine and laid upon the table 11 so that the -t wine will extend from the twine holder 28 and clamp, 25 around the packa e and through the needle-and over the p leys of needle bar b7.

finger 37 pivoted at the ner.

' tion' of this part of a ratchet wheel 49 the needle bar to the twine receptacle 1%. llhen this is being done the needle bar and needle are in an elevated position, as shown by dotted lines in Fig. 1, so that there is a metal arm between the knotter, hereafter explained, and the needle above it for lateral movement and placing of the package, as explained. The needle and needle bar are held normally in such elevated position by the spiral spring 130 which extends from the table 11 down t-o-a bracket 31 on the When the package is in place ready to be tied, the needle and needle bar are depressed by the operator placing h1s foot upon the foot piece 32 which is secured to the lower part of the needle,

bar 17, as shown in Figs. 1 and 5. That moves the needle down to the position shown in Figs. 1 and 10, so that it carries the twine between the knotter fingers 35 and 37. The knotter consists of a finger secured to the knotter shaft 36 which is mountedin the upper part of the frame 27 in a somewhat inclined position. There is another finger 35 and shaft 36 in a customary man- Tt is pivoted between its ends and carries a roller 38 on its upper end which engages the cam-like surface of the end of the portion of the frame 27 inwhich the shaft 36 is mounted. The arrangement and posiunderstood by those'skilled in the art as it is not difl'erent from what is common in tying mechanisms.

As the needle goes down it'moves the twine down through a slot 46 in a breast plate t1, see Fig. 2, so that it lies upon a finger 42 which is secured to said breast plate and projects across said slot arid yet is placed away from the breast plate, as appears in Fig. 3. At this time the other end of the twine lies under the linger d2 of the slot 40 so that both portions. of the twine, as shown in Fig. 10, at this stage of the operation will be in osition to be engaged by the knotter and w en the latter is given one revolution it will twist or knot the twine together. The knotter is actuated by a mutil ateol pinion 43, see Fig. 11, which engages a mutilated gear 44 on a shaft 45 mounted horizontally in the lower part of the frame 27 and said shaft carries a pinion 1-6 which meshes with a pinion at on a shaft l6 mounted in the main frame which carries adapted to be actuated by a pawl 50, see F ig. 8, which is mounted on the side of a gear 51 which rides loosely on the shaft 48 and is driven by a segmental gear 52which is pivoted at 53 in across bar 54 secured to the main frame, see Fig. 5, and is actuatedby an arm 56 pivoted in the upper end of a connecting bar 57 which, at its lower end, is pivoted to a foot lever 58 junction of the revolution during the revolution of the the mechanism will be surface of v the twine has been severed, the knot frame. W hen a peddle 61 on the lever 58 is depressed, the segmental gear 52 Wlll cause the mutilated gear it to give one revolution. This wheel has only a small portion of the periphery thereof provided with teeth but sufficient to give the knot-tor shaft one revolution and during the remaining revolution of the wheel 44:, a flattened portion of the pinion d3 rides on the smooth peri hery of the wheel at so that the knotter will e given no more than one revolution during each revolution of the wheel i l or during one operation of the machine. The segmental gear 52 is returned to its normal position by a spring 62 which extends from the arms 56 to the frame bar 60, see Fig. 5.

O n the-shaft 45, see Fig. 1, there is a mutilated gear 6 see Fig. 11, secured beside, the gear a l, and provided with a-front row of teeth meshing with a double segmental pinion 65 on a shaft 66 which carries the twine holder 28, said shaft 66 being mounted in the frame 27, see Fig. 1. The Jinion 65 has two oppositely located sets of teeth so that it and the shaft 66 are given one-half gear 64 or one operation of the machine. During the remaining revolution of the gear 64, the g flat side of the pinion 65 slides over the smooth periphery of the gear 64.

After the machine has been started in its operation by actuating the pedal lever 58,

the knotter is given a revolution which knots twine and immediately thereafter or ties the the twins is severed or out by one of the knives 70which is secured to the inner end the twin holder 28 and revolves therewith. and'their ends are curved over the periphery of the twine holder 26 so as to be paral' lel with the shaft 66.. The twine holder 28 is provided with recesses 71, see Fig. i, which as the twine holder revolves, the twine car ried by the twine holder enters said recess 1Z1, whereby the twine held by the holder There are two of these knives.

is carried in'against the clamp 25 and then the knife 70 severs the twine, leaving the end of the twine which passes through the needle, caught under the clamp. This part of the mechanism is substantially the same i as that used in twine binders and familiar to those skilled in the art and further expianation isthought to be needless. After is left on the lrnotter and that is removed or at? by means actuated by the needle bar 17 as it is returned after being depressed by the spring 130. shown in Fig. 5, one edge of that bar is provided with teeth 76 to form a rack bar. A gear 77 on a shaft 78 mounted to the main frame, see Figs. 5 and 6. The gear 7'? drives a gear 80 which rides loosely got-ten is secured in the bars 79 secured on a shaft 81 mounted in the bars 79 and which carries a pawl 82 and engages a ratchet wheel 83 secured on the shaft 81- and whereby the shaft is driven in only one direction and intermittently and is not affected by the return movement of the needle bar 17. The shaft 81 carries a pit-man wheel 84, see Fig. 6 with which a pltman 85 is pivoted, see l ig. 5, which, as seen in Figs. 13 and 14, has a pin 86 toward its upper end which projects through a slot 87 in a guide 88 so as to reciprocate a jaw 89. carried on the-extreme upper end of the pitmanf85;

The jaw 89 is fixed but associated therewith is a movable jaw 90 pivoted on the pin 86 having a downwardly extending shank 91 which engages a stationary spring 92 which is secured to the guide 88, see Fig, 16, and

curved so that as the pitman 85 is pushed upward, the movable jaw 90 will close down on the twine near the knot which haspreviously been formed. As the pitman 85 recedes, the spring 92 is so formed as to tighten the grip of the jaws on the twine still more and cause the receding movement of the jaws to pull the twine from the knotter, and when the pit-man 85 operates, its

lower portion or movable jaws relax and the jaws disengage the twine and the package is tied.

The cog portions of the wheels s4 and 6a i'egister'with each other radially, but as the I wheel 44 is of much greater diameter than the wheel 64, the segmental gear 43 will be given an entire revolution, while the gear. 65 is given only a half revolution, as shown f in Figs. 11 and 12. Also it is obvious that the knotter shaft will be operated faster than theshaft '66 which carries theknives so that the knot will be tied before the knife operates. There are two knives 70 diametrisegmental pinion, 65.
