WIRE STRAIGHTENING AND SWAGING liTACHI'NE.

Application filed June 14,1922. Serial No. 568,307.

. To all whom it may concern:

Be it known that we, Am J. GERRARD and PARVIN Vvnlorrr, respectively a subject of the King of Great Britainand a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in. Wire Straightening and Swaging Machines; and we do herebyde- 1o clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention relates to a wire straightening and swaging machine and has for its object to provide a machine which will be more eflicient in action and less costly to construct than those heretofore proposed.

With these and other objects 1n 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-'1 is a side elevational view of a machine made in accordance with this invention;

Figure 2 is a plan view of the parts shown in Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2 looking in the direc- 5 tion of the arrows;

Figure 4-is av sectional view taken on the line 4-4'of Figure 3 looking in the direction of the arrows;

Figure .5 is a detail view illustrating the swaging and cutting dies;

Fi re 6 is a view taken on the line 6-6 of Flgure 4, looking in the direction of the arrows; and

Figure 7 1s a detail view of the swaged '45 wire showing how the swaged parts are cut in two.

1 indicates any suitable base or support on which is mounted the shaft 2 of any suitable motor 3 provided with the power W pulley 4 around which passes the belt 5.

fit the springs 21, the upper ends of which Said belt also passes over the power pulley 6 rigid with the power shaft 7 carrying the pinion 8, meshing with the gear 9, mounted on the short shaft 10, carried by the swing- '16 and 17 as best illustrated in Figure 4,

and above these cams is positioned the swaging bar 18 provided with a plurality of die members 19 as shown. The said swagingbar is recessed at each end as indicated at 20 and 22, and into said recesses rest in the recesses 22 with which the cap members 23 are provided.

25 represents a stationary swaging bar provided with pivoted supports 26 resting in said cap members 23, and also carrying at its lower surface the swaging die members 27 as shown. The cams 16 and 1.7 dip into the oil cups 30 carried by the brass bushings, and are thereby kept in condition. The wire 35 comes into the machine from coils not shown, passes over pulleys 36, pivoted as at 37 to the levers 38, pivoted at 39 in the brackets 40 and provided with the notched trigger members 41. Goactin with each trigger member 41, is a pivot tri'gso ger 42 rigid with thecutting member-l3v into which the wire 35 passes into the machine and which is controlled by the spring 44. Should the. wire in its travel become knotted or tangled, its pulley 36 will be elevated which will depress its corresponding notch 41, thus releasing the trigger 42 which'causes the cutter 43 to sever the same, and thus will the particular tangled wire not stop the operation of the machine.

After the wire 35 has thus passed the cutter 43 it enters the barrel 45 of I the straightening mechanism 46, which is pro vided with the worm 47'engaging thegear 48,'Inounted on the shaft 49 operated by the sprocket 50, see Fig. 2, rigid with the shaft 7 over which passes the belt or sprocket chain 51; Said chain 51 also passes over the sprocket 52 rigid with the shaft 49 and thus is the worm 47 and'barrel 45lturned, The 100 continuous and is provided 'with grooved surfaces as best indicated in Fig. 3, while a plurality of short rolls 56 are mounted on short stud shafts 57 carried in the individual frames 58. Each of the short. rolls 56 are provided with grooved surfaces 59 which are adapted to coact with the grooved surfaces of the rolls 55, and to frictionally engage the wire' strands between them. Each of said rolls 56 is provided with a gear 60, as best shown in Fi res 2 and 3, and the roll 55 is provided with a plurality of similar gears 61 which mesh with said gears 60; and thus are the individual short rolls 56 positively turned from the continuous longer roll 55. As will be readily understood from Fig. 2 of the drawings, there are a plurality of wires being drawn through a plurality of straighteners 46, and

.undera plurality of cutters'43, simultaneously.

- After a wire strand 35 is thus forcibly drawn through its straightener 46, it is.

pushed forward by the said rolls 55 and 56 between the cutting and swaging dies 19 and 27, as will be clear from Figures 3 and 4. The swaging die 27 is held stationary in its supporting ar 25 while the swagin die 19 is raised vertically by the action of t e cams 16 and 17 to cut and deform the wire into the shape shown in Fig. 7. That is to say, in the types of wire tying machines which have been recently developed, it is very desirable indeed that the tie wires be provided with the depressions such as 62 providing the holding shoulders 63 in each end of the -,wire and this machine accomplishes this It is often convenient to change and to re pair the cutting dies 19 and 27 and with the construction just illustrated, by loosening up a few bolts and nuts the bar 25 can be readily turned-onits pivots 26 through an angle of 90 or 180 which notonly exposes the die member 27, but also the die members 19. This movement of the bar 25 will be readily understood from the detailed view shown in Fig. 6, wherein there is shown a. stationary stop member 81, ada ted to contact with one side of the pivot swaging bar 25, as well as a pivoted stop member 82 ada ted to contact with the other side of sai bar 25. The members 81 and 82-are conveniently secured to the capmember 23, and the member 82 is ca able of swinging around its pivot 83, to re ease the bar 25 and permit it to swing from its full line osition to its dotted line position shown ,in' igure 6.

During the cutting and swaging o eration it is desirable that themotion o the various wires 35 be stopped andzto this end the swaging plate 18 is provided with the extension 65, best shown in Fi 3, on which rests the set screws 66 with w ich the various individual frames 58 are provided. It thus results that when the swaging plate -or bar 18 is elevated to deform the wires 35, all of the frames 58 are raised at their ends carrying the screws 66 and the raising of these ends raises each individual short roll 56a very slight distance.

This said distance is suflicient to decrease the friction between the several rolls 56 and the several surfaces of the roll 55 so that the various wires are stopped in their motion. The said frames 58 are pivoted on s'tuds 96 indicated in Figures 1 and 2, to permit this slight movement. Said short frames 58 are also provided with adjustable screws 97 resting upon the frame work, as best shown in Fig. 1, in order'that the desired friction on the wires may be accurately attained.

After the various wires 35 are thus deformed and severed in the manner disclosed, their cut ends are carried out of the machine by means of the rolls 70 and 71mounted on the shafts 72 and 73, respectively. The shaft 72 is driven by the sprocket 75 ri id therewith, over which passes the sproc et chain 76 driven by the sprocket 77 rigid with the power shaft 7, as will be clear from Fig. 2. I

As these straightened out and swa ed tie wires are intendedto band boxes an packages of various sizes, it is evident that a single length of wire would not be suitable for all purposes. Therefore, it is desirable to change the lengths of the wires cut by this machine. In order to do this, it is only necessary to change the multiplying gears 9 and 13. These said gears are carried on the lever like means 11 which is preferably made of two parallel arms as best shown in Fig. 4. These said arms carry thestuds 80 between which are mounted the gears 9 and 13, so that it is only necessary to remove the said gears and their pivot 10 and to sub stitute gears of the proper size'to feed the desired lengths of wire through the swaging mechanism before the cutting action takes place. a

It is obvious that those skilled in the art may vary. the details of construction as well as the arran ement of fparts without departing from t e spirit 0 the invention, and therefore, it is desired not to be limited .to the above disclosure except as may be required by the claims.
