WIBEWOBKING MACHINE.

Application led February 16, 1927. SeriallNo. 168,684.

My invention has to do more especially with the cutting olf and delivery of cut off lengths of wires from the machine, and, therefore, only a brief description of the machine in general and as shown in the drawings herein Will be given, such machine comJ prising a bed 10 supporting a frame 11 upon the latter of which driving and operating mechanism is supported, this mechanism being of any ordinary type and construction and which may include a motor 12 for driving such mechanism with feed rolls 13 and breaker rolls 14 for supplying wire to a flier or straightening arbor 15.

The flier 15 is supported between bearings 16v-17 and a burnisher 18 is located between the bearing 17 and a pair of feed rolls 19. This burnisher is not illustrated in detail herein but forms the subject matter of a se arate application'led by me concurrent y herewith and, therefore, no claims to the de tails of the construction are made herein.

. My invention comprises a mechanism for cutting the Wire into definite lengths as it passes from the burnisher and the feed rolls 19, this mechanism being caused to travel by and With the wire as the latter is moved.

This cutting mechanism comprises a supporting sleeve 20 secured Within and projecting from the side of albracket 21 attached to the end of the frame 11, a carrier sleeve 22 belng mounted upon the sleeve 20 and movable lengthwise thereon, one end of this sleeve 22 being slidably supported in a side of said bracket opposite the end of t-he supporting sleeve 20. A retracting spring 23 is secured within the sleeves 20 and 22 and at opposite ends of each, so that when the sleeve 22 is moved j in a manner to be hereinafter described it will, when released, be moved to its normal position by means of the spring.

A cutter frame is carried by the sleeve 22 and comprises a die carrying arm 24, a supporting arm 25 and a cutting arm 26. The arms 24 and 25 are secured to the sleeve 22 in a manner to prevent movement of said arms lengthwise of the sleeve, but to permit said sleeve to rotate within said arms, and the cutting arm 26 is secured to said sleeve that forms an immediate support for said arm and that is rotatable upon the sleeve 20.

The arms 24 and 25 are provided with actuating rollers 27-28 rotatably mounted on studs at the ends of the arms and in engagement with a cam sleeve 29 on a shaft 30 rotatably. mounted in one of the sides of the bracket 21 hereinbefore mentioned and a bearing in a bracket 31 secured to the frame 11, and as shown in Figure 1 of the drawings. The shaft 30 is driven as by means of intermeshing pinions and gears from a shaft 32 connected by a train of gearing 33 with the motor 12, and as shown in Figures 3 and 4 'of the drawings, said shaft also being connected by intermeshing gears to drive the breaker rolls 14 and feed rolls 19, in a manner that will be readily understood without further illustration and description herein. The cutting arm 26 also has a roller 34 in contact with a cutter operating cam 35 secured to the sleeve 29. f

In the operation of this cutting mechanism a wire 36 is fed through the straightening arbor 15 and burnisher 18 by means of the feed rolls hereinbefore described, and

Cal

through ya hole in a cutting die in the arm 24, and thence into a receiver 37. This receiver 37 comprises a bar with a roove in its under surface into which the wire passes and within which itengages a trip block 38 connected by a rod 39 with a clutch actuating lever 40 rotatably mounted on a wire receiving frame, to be hereinafter described. The lever 40 comprises an arm 41 having a connection 42 with a clutch actuator bar 43 appurtenant to a one revolution clutch 44 mounted on the shaft 30, and as shown in Figure 1 of the drawings.

This one revolution clutch may be of any ordinary construction well known to. those skilled in the art and in the operation of which, when the bar 43 is actuated will make one com lete rotation and then stop. When the bar 1s actuated by a length of wire passing along the receiver, as herein just described, the operation of the clutch will Set the shaft 30 in motion thereby rotating the sleeve 29 and actuating the cam 35 to swing the arm 26 and the sleeve 22 on the supporting sleeve 20. As soon as the cutting device on the arm 26 encounters the wire the latter will move the sleeve 22 together with the arms 24-25-26, the cutting device thus moving simultaneously with the wire to sever the end thereof. The cam 35 is very short as shown in Fig. 6 and the action of the arm 26 is, therefore, comparatively' quick. Consequently, as soon as the end of the wire is severed the arm 26 reti-acts and the spring 23 returns the sleeve 22 and said arms to their normal position, and as shown in Figure l.

It will be noted that the arms 24-25-26 are partly supported by the sleeve 22 on the sleeve 20, and in order to prevent cramping action as force is applied to the cutter to move it with the wire the. rollers 27-28-34 are so inclined on the sleeve 29 that rotation of said sleeve will tend to move these ends of said arms in the same direction as that in which the sleeve 22 is moving, and this construction enables the cutting apparatus to be su ported on a single bearing.

{re supports 45 in the shape of fingers are secured to a rocking bar 46 mounted on a receiving frame including supports 47. These fingers underlie the groove in the receiver 37 hereinbefore referred to and the wire in said groove` rests upon these fingers. The bar 46 has a bar actuating arm 48 connected by a rod 49 with a wire releasing lever 50 pivotally mounted on the bracket 2l and having a roller 5l engaging a cam surface 52 on the sleeve 29, and as shown in Figures 5 and 6 of the drawings.

In the operation of the wire releasing mechanism just described, when the cam sleeve 29 has been set in motion by the operation of the clutch 44 as hereinbrtore referred to, the releasing lever 50 will be operated to withdrawthe wire supports or fingers 45 and permit the wire to drop on to wire rests 53 where they are retained by jaws 5 4. The cam 52 is so positioned that this release of the wire will take place just before the arm of the lever 26 is operated to sever the next succeeding length of wire.

The clutch actuator bar 43 has a latch 55 spring pressed to enfrage one end thereof with a clutch trip 56Ll1aving a stop arm 57 adapted to be interposed in the path of movement of a nose, 58 of the clutch 44 hereinbefore referred to and of ordinary con struction, and which will be set into clutching action when the arm 57 is moved from engagement with the nose 58 by operation of ithe bar 43 in a manner that will be readily tunderstood, springs 59-60 returning the parts to their normal positions as soon as a wire has been severed as hereinbefore described, and the stop 57 being thusin position to engage the nose 58 and stop operation of the clutch at the end of each complete rotation thereof.

As hereinbefore noted the cutter mechanism is supported upon a single bearing, this being the sleeve 20 upon which it has an easy sliding fit, the opposite ends of the several levers with their diagonally arranged rollers aiding in the movement of the structure along said sleeve. The arms 24 and 25 are rigidly connected at their ends opposite the supporting rollers by a tie 61.

The wire supporting fingers 45 are held normally underneath the groove in the bar or receiver 37 by means of a spring 62 in a case 63 pressing against a rod 64 pivotally connected with the wire support 45, and as shown in Figure l0 of the drawings.

rThe trip block 38 has guide plates 65 slidably fitting grooves in the receiver 37, and as shown in Figure 10 and by means of which an easy sliding movement of said trip block is provided for.

A treadle 66 is attached near each end of a wire discharge shaft 67 rotatably mounted in the frame supports 47, said treadles being connected by bars 68 with each of the jaws 54, whereby upon pressure as of a foot upon either treadle said jaws will be swung downwardly to permit wires collected on the rests 53 to slide therefrom and be discharged from the machine.

In order to provide for a quick discharge of the wires from the jaws 54 the bar 68 is pivotally attached at its lower end to a toggle lever 69 loosely mounted on the shaft 67 and underlying the treadle 66, and as shown in Figure 2 of the drawings. When the jaws 54 are in their receiving positions, as shown in Figure 3, the pivot connecting the bar 68 and toggle 69 will be at one side of a line extending between the axes of the shaft 67 and the pivot connecting the bar 68 with the jaws 54, in which position the toggle rests against sin a tube ormin a part of the wire dis char e frame, so t at pressure upon lthe )aws 54 will tend to force the toggle into contact with said tube. Pressure of the treadle 66 will move said pivot to the opposite side of said line, whereupon there beln no further resistance to movement of the ]aws 54 they will swing quickly downwardly b reason of the weight of the wires, thereby ischargmg the latter. It is here remarked that the jaws 54 are secured to a rock shaft 71 rotatably mounted in the frame supports 47.

In accordance with the provisions of the patent statutes I have ldescribed the principles of o eration of m lnvention, together with the evice which now consider to represent the best embodiment thereof; but I desire to have it understood that `the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
