This invention relates to a pull-out device and more particularly to such a device in combination with a machine for straightening and cutting lengths of wire or rod.
An object of the present invention is to facilitate the straightening of the last length of a heavy wire or rod straightened from a reel of the same for the purpose of cutting the wire or rod into pieces of predetermined length.
Another object of the present invention is to provide a novel vise or clamping means guided in such a manner that it prevents the wire or rod from turning and twisting as the last end is pulled through the straightening arbor.
Another object of the invention is to provide a novel means for supporting a vise or clamp for movement lengthwise of the path traveled by the wire or rod to be cut.
Another object of the invention is to provide a novel toggle-operated clamp for firmly gripping the wire to insure that it does not turn or twist as the last end is drawn through the straightening arbor.
Another object of the present invention is to provide in combination with a straighten-and-cut machine wherein a guide bar normally holds the wire or rod in proper position for gaging and cutting, novel means for moving the guide bar out of the way when my improved pull-out device is operating. This novel means comprises a cam on the traveling vise, a follower, adapted to cause movement of the guide bar to the desired position, and latch means for holding the guide bar out of the way.
Other objects and advantages of my inven- --tion will be apparent from the accompanying drawings and description, and the essential features thereof will be set forth in the appended claims.

The device here disclosed and claimed is an improvement on the wire cutting machine shown in Patent No. 2,101,860 granted December 14, 1937, to Marvin W. Lewis and Carl B. Jones, to which patent reference may be had for details not described in the present application.
In this type of machine, as shown in the previous application and as shown in Fig. 1 of this application, a long length of wire or rod in coil "form 20 is supported on a rotatable reel 2!. The
free end of this rod is fed through a set of straightening rolls 22 then through a rotatable straightening arbor 23 (which crimps the wire back and forth while rotatin about it), and a final set of feed rolls 24 to the straightening and cutting portion of the machine at the right-hand end, as viewed in Fig. 1. The rod then passes through a shear head 25, which in all respects is like the shear head 2| of the above mentioned patent. This carries a vertically reciprocable blade for cutting the rod.
The length of rod to be cut passes through a guide bar 26, best seen in Figs. 6 and 7, which is of slightly different form than that shown in the earlier patent but which performs a similar function. It will be noted that this guid bar in the position of Fig. 6 supports the rod 20 as a length of the same is run out to be gaged and out. In the present form the guide bar has a somewhat semicylindrical recess 26a open at one side for the discharge of the cut rod. As shown in Fig. 6, while the rod is being gaged and cut it is held in the recess 26a by means of a clapper bar 21 which sufficiently closes the recess to hold the rod in the guide bar. Normally, as disclosed in the above mentioned patent, the guide bar is swung downwardly to a position similar to Fig. 7, except not quite so far, in order to dump the cut length of rod, as explained in detail in the prior patent. This is accomplished by means of a 01- lower 28, shown in Fig. 1, which is engaged by a cam on the side of the shear head 25 so as to dump the cut piece at the proper time. As shown in Fig. '7, the clapper bar is supported by arms 2%] which are pivotally mounted on one or more of the machine frame brackets 30 for pivoting motion around the point 3|. The rear end of arm 2!; is pivotally connected with a link 32 which in turn is pivotally mounted on the frame at 33. It results from this construction that when the guide bar 26 is moved from the position of Fig. 6 to that of Fig.- .7, the clapper bar ismoved farther in a counter-clockwise direction so: as to open up the recess 26a as shown in Fig. 7. Since the guide bar and clapper bar have considerable length in this type of machine, say of the order of 10 to 16 feet, it is necessary to provide a nurhb'er of supporting arms spaced along their-length. For this purpose, a guide bar control 'sh'aft M'is rotatably mounted in a number oi-thei'm-achine frame brackets 38. clamped or otherwise rigidly secured to this shaft are a number of arms '35 which carry at their lower ends the angular arm extensiontea which is 'conne'cted*with the guide bar 26. It is this arm 35-iv1'iichsupports the "pivot-point 3i -p'reviously-mentioned.' Means is provided for urging the fgu'idebanarm dfia' for movement in-a clockwise direction, -as viewed in Fig. 7. This comprises -a numberbf springs -3'l connected-between thepivotpinsconnecting arms 29 and links -32 andpins SFon-the machine frame (Fig. 12). This biases theguide hartoward the position of Fig. 6 at all -times whenitisnot under the control-of oneofits operating cams. The
follower 28 (Fig. l) is carried by and 28a clamped to theleft end of -sh aft td (Fig. 4) and serves to oscillate shaft 34,
- Hand operated -means "is also provided for- -op'ening the-clapper bar. This comprises a handie- 39 'rigidly faste'nedtoshaft' Z-tand-having at its lower endgas bestseenin'Fig. 6*a stop'mem- "ber 39a-whichengagesa stop Q'fid on one of the machine brackets :30. The stop merhber tfia extends laterallyat 39b; asshownin Figs. -and 7,
to provide a -rnounting-means'for pin ill-which is connected by-spring 'M with pin 42=-which is mount'ed on bracket '43- connected with the machine" frame. *"Thus; *the spring I: always tends -to return handle tfi-to theposition shown in Fig. sane also aids in returning the guide-bar tothe "position ofFigi 6.
-A ieature present in the above'mention'ed-patem; and I in the present device-also. should be understood although --it has "no i-mme'diate bear- *ing on the present invention.

It shouldbe understood. that in the-machine under discussion,- the portion-atthe right-hand end of Fig. 1; a part ofwhich-is shown'in Fig.2,
is of a length of the order of ll) tolSfeet-forthe' cutting of longer lengthsof-rod andtherefore; a number of the machine bracketed!)araneceSSary, spaced approximately 30-iriches apart on the-subframemember 46 and provid'edwitlrasuifioient I number'of supporting legs '41.
a When theend of a-long-=-coil 20--is'- reached-so that the coil runs-free of 'the reel 2 l-iin thtype ofmachine shown "in the previous patennithere was nothing toprevent thebending and whipping l ofthis last-piece -oi wire or r'od. A l his bending 4 and whipping is caused by the straightening device, more particularly the rotating arbor 23. As a result of this action, the last length of rod became snarled and was of no commercial value. 5 This Was of no importance in smaller diameters of wire but in rods one-half inch and threequarters of an inch in diameter, the loss of a length of or 16 feet of rod due to this cause was of serious commercial importance. The 10 present invention does away with this loss.
As best seen in Figs. 4' to 10 inclusive, 2. vise generally indicated at 48, is mounted for sliding movement lengthwise of the machine just above l'lthez'rod 20. The mounting means comprises a p rectangularly shaped way 59 supported from above by the'machine brackets 30. The vise is formedwith a c shape portion 58 which embraces the way 49 so as to slidably mount the vise 48 on the way 49. It results from the embracing structure 533 about the way 49 that it is impossible for :the vise 48 to oscillate or" rotate: l'transversely pf the rod 20. I
As best seenlin Figs.

This is of the order of a few thousandths of an inch, but is suflicient to give additional driving force to the rod 20.
Since the guide bar 26 would interfere with the operation of the vise 48 as above described, means is provided for taking the guide bar and clapper bar out of the way, as shown in Fig. 7. This means is more clearly shown in Figs. and 11. On the shaft 34 is rigidly clamped an arm 11 which extends downwardly from the shaft and then is bent at right angles to support the rotatable roller '18. On the side of vise 48, is clamped acam. bracket 19 by means of bolts 80. The cam bracket supports a cam 8| which slopes outwardly and downwardly, as shown in Figs. 10 and 11. As viewed in Fig. 4, the cam extends toward the top of the sheet as one moves toward the left and the cam face extends downwardly toward the left also. In other words, the roller 18 is in the same position in Fig. 4 as it is in Figs. 10 and 11. It results from this construction that when the vise 48 (which normally is at rest near the shear head 25) is clamped on the rod and starts to move toward the right as viewed in Figs. 1, 4 and 5, the cam surface 8| forces the roller 18 downwardly and follows it in a counter-clockwise direction so as to move arm TI to the dot-dash position of Fig. 10 or to the position shown in Fig. 7. This moves the guide bar 26 to the position shown in Fig. '7 which is slightly beyond the normal position to which it is forced by the action of the follower 28 operated by the shear head 25 as previously described.
After the guide bar is moved out of the way, latching means is provided for holding it there.
This is best seen in Figs. 6 and 7. Secured to one -i of the frame brackets 30 is a fixed latch member 82 which coacts with a movable latch member 83 pivotally mounted at 84 on arm 85 which is rigid with guide bar control shaft 34. The rear end of latch member 83, as indicated at 83b; is urged upwardly by a spring 86 which is held in compression against a shoulder 85a formed integrally with the arm 85. An upstanding pin 85b is embraced by the helical spring at its lower end and a recess 8'? in the latch member holds the upper end of the spring. A handle 88 is provided for manipulation of the latch member. Coacting shoulders 830. on the movable latch member and 82a on the fixed latch member are engageable,
as shown in Fig. 7, to hold the guide bar out of the way while my improved vise 48 is being used. Normally however, the latch member 83 rides on the surface 8% of the member 82 each time the guide bar and clapper bar are operated to dump a cut length of wire, as described in connection with the follower member 28. This follower member 28 does not operate the latch nose 83 far enough to engage the shoulder 82a, as shown in Fig. 7. This holding engagement is also possible when the handle 39 is moved toward the left, as viewed in Fig. 6, engaging against the pin 840, which extends out from the pivot point 84, as best seen in Fig. 5. Either this hand operation of handle 39 or the operation of cam BI and follower 1'8 is relied upon to lock the latch members 82 and 83 in the position of Fig. '7 to hold the guide bar out of the way during a pull-out operation. To release the latch from the position of Fig. '7, handle 88 is pushed downwardly, whereupon the springs 31 and Al return the guide bar to mal position.
