PARVIN WRIGHT, OF CHICAGO, ILLINOIS.

MACHINE FOR TYING BUNDLES OF WIRES.

Application led February 18, 1922. Serial No. 537,610.

To all whom it may concem:

Be it known that I, PARvrN VRIGHT, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois', have invented certain newA and use- --ful Improvements in Machines for Tying Bundles of Wires; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a machine for placing caps on bundles of tie wires and then placing tied wires around said bundles, twisting the ends thereof together and cutting oif the twisted ends preparatory to shipment, and has for its object to provide a mechanism of this character which will be simple in construction, comparatively inexpensive to manufacture and more eiiicient in use than those heretofore proposed.

With these and other objectsin view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views;

Figure 9 is a detail plan view illustrating a portion of the twister mechanism;

Figure 10 is a detail view illustrating the twisting element or hook; and

Figure 11 illustrates a. portion of a bundle of -tie Wires after its tied wire has been twisted and severed.

Referring more particularly to Figs. 1, 2

and 3, 1 indicates any suitable frame work' supporting the mechanism, 2 any suitable motor, provided with a driving pulley 3 over which passes a belt 4. This belt also gasses over the pulley 6 carried-by shaft 5.

igld with the shaft 5 is the driving pinion 7 meshing with the driving gear 8 mounted on the stud shaft 9, meshing with the driving gear 10 mounted on the stud shaft 11. Rigid with the driving gear 8 and also mounted on the said shaft 9 is the mutilated gear 12 having the gear teeth 13. the smooth portion 14 and the cutaway smooth portion 15, all as will be clear from Figure 2. Also mounted on the stud shaft 11 and rigid with the driving gear 10 is the multilated gear 16 having the smooth portion 17, the cutaway smooth portion 18 and the gear teeth 25, all as will likewise be clear from Fig. 2.

Mounted on the frame 1 of the machine and extendingy from end to end thereof is the oscillating shaft 20 carrying at one end rigidly attached thereto a pair of mutilated oscillating` gears 21 and 23 each having the smooth portions 22 as best4 illustrated in Figures 1 and 2.

The parts are so proportioned and timed that after the teeth 13 of the gear 12 have engaged the teeth of the pinion 21, and thus turned the shaft 20 in one direction. the teeth 25 of the mutilated gear 16 will engage the companion pinion 23 and turn the oscillating shaft 20 in the opposite direction, all as will appear more fully hereinafter.

vThe mutilated gear 16 carries a pin 26, see Fig. 2, which plays in a slot 27 of a reciprocating pitman 28, pivoted as at 29 to the crank arm 30 rigid withthe oscillating shaft 31 which likewise extends from end to end of the machine. see Fig. 1. It therefore results that as the motor 2 continues to revolve the shaft-s 20 and 3l will be continuously oscillated at predetermined intervals depending upon the speed of the motor. The shaft 20 is provided with a driving oscillating bevel pinion 33 which meshes with a bevel pinion 34 rigid with the shaft 35 all as will be clear from Figs. 1 and 6.

Rigid with the 'shaft 35 is a member 36 carrying a spring pressed pand/37 taking in member 43 carried by the reciprocating bar v 44 and in the cam slot 41 plays the roller member 45 carried by thereicprocating bar 46, so that as said cams revolve, sa1d bars 44 and 46 are reciprocated, all as wlll be clear from Figs. 6, 7, and 8.

Distributed along the length of said shaft 20 are also the plurality of bevel osclllating pinions 50 meshing with the companion twisting pinions 51 carried by the plurahty of short shafts 52, each having rigldly attached thereto a slotted twisting hook 53 or its equivalent, see Figs. 9 and 10.

Rigidly mounted on the shaft 31, and oscillating therewith, as will be clear from Figs. 1 and 4, are a plurality of wire carryin needle members 56 having the roller memers 57 in their outer ends over which pass the wires 58 supplied by reels or other means not shown.

Mounted on the supports 60 carried by the frame 1, are a pair of motors 61 and 62 each driving a gear 63 and crank 64 which reciprocates a pitman 65. Also carried by said supports 60 are a pair of stud shafts or supports 66 on which are revolubly mounted a plurality of segmental cone shaped members 67 adapted to receive the ends of a bundle of tie wires to be capped. The capping mechanism forms no part of this invention, but it is or may be constructed substantially in accordance with my copending application, Sr. No. 526046. filed Dec. 30, 1921, and entitled Machine. for capping` bundles of tie wires. Suffice it to say that the power for the capping opera.- tions is derived from the pitmen 65 and the plurality of collapsiblel cone shaped members 67, are or may beof different dimensions to facilitate the capping of bundle ends of different sizes.

The bundles 68 of wire having received the end caps` normally rest in the supports 70, see Figs. 1, 3, 4 and 5 which are carried by the frame 1, and they are lowered from these supports to the pivoted supporting arms 72 carried by the shaft 73 and which are held in their upright positions by the pawls 74, pivoting with the shaft 75. all as will be clear from Figs. 5 and 4. Normally as the bundles 68 arelowered from their supports by hand or by suitable mechanism not shown they strike the fixed guide surface 76 and strike the wires 58 which lie across their paths as said bundles are guided into said supports 72. The extreme severed ends of the wire being caught and held by the reciprocating cutter bar 46 between its flat side and its guide surfaces in the manner well known, the wires pass over the rollers 57 of the needles 56 and partially encircle a bundle 68 when it reaches the position shown in Figure 4. The shaft 31 being now rotated on its axis by -the means just described to bring the needles 56 from their ositions shown in Fig. 4 to those shown 1n Fig. 5, the wire completely encircles said bundle 68. Vhen this last named position is reached, theI shoes 78 carried by the needle bars will yieldingly press on the bundle of wires under the influence of the springs 79 and thus serve to bring the individual Wires of the bundle more closely together. rlhese spring cushioned shoes will further serve to facilitate the handling of bundles of different sizes. rllhe parts are so timed and proportioned that when the positions indicated in Fig. 5 have been reached the two bights 80 and 81 of the wire will occupy the positions shown in Figs. 8 and 10, and the rotation of the pinions 51 and twister hooks 53 will twist said bights together in the manner well known. Immediately after the twisting operation the cam slot 40 will pull the cutter bar 44 to the left as seen in Figs. 6 and 8, and will thus sever both bights 8O and 81, as indicated in Fig. 11, and at the same time bend the twisted knot 82 into the position shown. An instant later, the cutter bar 46 will be suddenly pushed to the right as seen in Figs. 6 and 7, whereupon the held end 80 of the wire will be released and the needle end 81 will be caught in the slot 84 as will be clear from Figs. 6 and 7. An instant later the cutter bar 46 will be suddenly moved to the left as seen in said Figs. 6 and 7, and the needle end 81 of the wire will be severed and caught in the osition indicated at 80. Fig. 6. The twisted portion 85, Fig. 9, being now completely severed, Will drop to the floor, and upon a reversal of the rotation of shaft 31, the parts will be restored to the positions indicated in Fig. 4. The bundle 68 having been thus tied with as many wires 86 as there are needle members 56, the finished bundle 68 is discharged from the machine as follows: Carried on the gear 10, Fig. 3, is a pivoted member 88 which strikes a pin 89 on the left hand member 74 which is rigid with the shaft 75, and thus are all the other supporting pawls carried by said shaft rocked out of engagement with their corresponding supporting members 72, the result is said members 72 will fall from their full line position shown in Figure 5 to their dotted line position shown in said Figure, and the bundles 68 4follow the guiding member 76 on their way from the machine. The supports 72 are restored to their normal positions b v turning the guide 7 6 and shaft 73 and then turninof the shaft 75 through the handle 90 to cause the pawls 74 to reengage said supports 72.

The operation of this machine will be understood from the foregoing but may be briefly summarized as follows A bundle of wires 68 being brought to the machine, it is rested in the supports 70 whereupon its left hand end may be thrust into the appropriate collapsible cone shaped member 67 which is adapted to cap a bundle of the particular size in hand. The capping head is conveniently turned and locked in place by mechanism not shown so that the desired cone shaped member 67 will be opposite the end of the bundle to be capped. The motor 61 is then conveniently started as by operating the switch lever 98 and a cap 69 is placed on the bundle 68 in the manner fully disclosed in my said copending application above mentioned. The vleft hand end of the bundle having thus received its cap 69 a similar operation is performed on the right hand end of the bundle and the corresponding motor 62 is started by manipulatingits switch lever 91. The bundle having thus received its two caps 69 it is brought from the position shown in Fig. 4, resting on the supports 70 by hand or by any suitable mechanism not shown to the position shown in said figure resting 011 the supports 72. In the meantime the guides 76 will aid in carrying the bundle 68 which is quite heavy to the last named position, and t-he swinging of said guides will turn the shaft 73 and bring all the supports 72 up to the position shown in Fig. 4, whereupon they are held there by the supporting dogs 74 under the manipulation of the lever 90 as will be readily understood.

The positioning of the bundle 68 on the supports 72 causes said bundle to cross the positions of the various wires 58 which are carried by the various needles 56 and thus do said wires 58 encircle portions of the bundle as will be clear from Fig. 4.

The motor 2 may be started now by a suitable switch or other mechanism, not illustrated, whereupon the belt'4 will turn the pulley 6, the shaft 5 and the pinion 7 meshing with the gear 8 which meshes with the gear 10; and the turning of said gears 8 and 10 will turn their companion mutilated gears 12 and 16. These mutilated gears mesh at predetermined intervals with the gears 21 and 23 carried by the shaft 2() and thus is the said shaft 2O osc-illated through predetermined arcs at predetermined intervals. The turning of the mutilated gear 16 further through the pin 26, the pitman 28 and crank 30 oscillates the shaft 31 at predetermined intervals. `The oscillation of the shaft 31 carries the various needles 56 from their positions indicated in Fig. 4 to their positions indicated in Fig. 5, so that the various wires 58 are caused to completely encircle the bundle 68 at a plurality of points. The oscillatiorfl of the shaft oscillates the pinions 33 and 34, and shaft 35 which has fixed rigidly thereto the collar 36 carrying the spring pressed pawl 37'engaging a notch in the cam wheel 38.

at 1s to say, when the shaft 20 makes a complete turn in one direction, it will, through the pawl 37, cause each of the cam slots and 41 to make a complete turn, in a given direction. But, when the shaft 20 4makes a complete turn in the opposite direction the pawl 37, which is beveled as at 99, rides out of its notch in a manner well known and thus fails to turn the cam member 38 at all. That is, it merely rides around the hub of said cam member, and reengages its notch ready to give said cams 40 and 41 another complete turn when the shaft 20 makes a second complete turn in the direction first mentioned. It thus results, that the cam slots 40 and 41 are given complete turns at every other oscillation of the shaft 20 and by this means the cutter bars 44 and 46 are given reciprocating motions at eve other oscillation of the shaft 20. Said cutter bars are provided at each needle bar with the notches 95 and 84 as illustrated, and these notches are disposed opposite the twister elements 53. The arrangement and operation isy such that when the various needle bars are brought into the positions shown in Fig. 5 the previously severed end of the wire 58 is still held between the cutter bar 46 and its guide support 96 see Fig. 6, and its unsevered bight 81 is brought down into the notch 84 of the cutter bar 46, while both of the bights orpportions 8O and 81 of the wire are disposed in the twist-ing element 53 in the mailer well known, and somewhat after the manner illustrated in Fig. 10. The parts are so timed and proportioned that as the said shaft .20 turns 1n one direction and rotates the various smaller sized pinions 51 through the bevelled gears 50, a predetermined nurnber of twistsare imparted to the various smaller sized pinions 51 through the bevelled gears 50, a predetermined number of twists are imparted to the various pairs of bights 80 and 81 by the twisting members 53, and as soon as this is accomplished the cutter bar 44 is drawn toward the left as seen in Figures 6,'8 and 11, to the end that a twisted portion of the wire is severed at each needle bar and a portion 82 thereof is bent down into the position illustrated in Figure 11. An instant later, the cam slot 41 pushesl the bar 46 toward the right as seen in Fig. 7, and the upper bight 81 of the wire at each needle bar which an instant previously had been brought down into its corresponding notch 84 is severed in the manner well known in that class of invention.

The severing of this bight 81 disengages the severed portions 85 of the twisted wireV and the latter drops out of the machine, while said Vbar tucks the end 80 attached to the needle down between the body of the cutter bar 46 and its guide support 96 all as indicated at 80 in Fig. 6. The parts are now ready for another operation. In the meantime, by manipulating the lever 90, see Fig. 4, all of the supports 72 are permitted to drop into the dotted line positions shown in Fig. 5, and the tied bundle 68' is discharged from the machine.

It is obvious that those skilled in the art Vmay vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore, I do not wish to be limited to the above disclosure except as may be required by the claims.
