l Claims. (Cl. 140-140) My invention relates more particularly to that class of wire. Working machines which are employed for cutting lengths of wire into comparatively short pieces after being straightened, commonly in the machines of which my invention forms a part and which lengths of wire may be extended from a coil, not herein shown, and an object of` my invention, among others, is the production of a machine of simple construction which will operate to rapidly cut the wire into accurately even lengths and particularly without creating marks on the lengths of wire produced in the cutting operation.

One form of a machine embodying my invention and in the construction and use of which the objects herein set out, as well as others, may` be attained is illustrated in the accompanying drawings, in which- Figure 1 is a view in front elevation of my improved Wire working machine with parts omitted as not material to an understanding of the invention.

Figure '7 is a view in f ront elevation of the mechanism for operating the cutter, the scale being slightly enlarged o-ver that shown in Fig. 3.

Figure 8 is a view in section on a plane denoted by the dotted line 8 8 oi Fig. 5.

My invention has to do more particularly with the mechanism for operating the cutter that severs the wire and to the means for controlling the 7' operations of the cutter and while, in order to disclose enough for a clear understanding of the operation of the machine, some' parts not otherwise pertaining to the invention are shown such parts will be only briey described herein. In the accompanying drawings the numeral I0 denotes generally the base of the machine comprising the wire straightening and cutting `part, thisbase being of any desired construction `and having'mounted thereon a straightening set of rolls generally denoted by the numeral Il, to-

gether with a straightening arbor I2 and a second set of feed rolls I3, the Wire I4 being fed from a coil (not shown) through the set of rolls I I, the arbor I2 and the set of rolls I3 in-.a manner common to machines of this type. 'I'hese straightening elements are suitably connected to be driven as from a motor I5, the driving connections being of any suitable kcharacter common to machines of this class and for whichE reason a more detailed showing and description of the operation is omitted herein. A driving shaft I6 is mounted on the base of 'the machine and is connected in any suitable manner with the motor' l5, the showing of such connection also being omitted herein. The connection between this 15 driving shaft I6 and a carrier driving shaft i1y comprises a bevel pinion I8 meshing with a bevel gear I9 in mesh with a pinion 20 the teeth of which are engaged with the teeth of a driving gear 2| secured to the shaft I1, as shown in- Fig. 20 3 of the drawings. The shaft I1 is mounted in any suitable manner on the base of the machine.

A brake drum 22 secured to the shaft I1 is engaged by a brake band 23 secured at one end t0 the frame of the machine and at its opposite end 25 to a brake .operating lever 24 pivotally mounted on the frame, or base as shown in Fig. 3, and operated in any suitable manner as by means of a cam operated by the shaft I1, the cam being timed to operate the brake to slow rotation of 30 the shaft I1 at such times as may be desired, a further and detailed description of this brake mechanism being omitted as not essential to an understanding of the invention, it being noted that the brake is operated to slow the operation of the mechanism for brief periods only, particularly during operation of the clutch hereinafter described. A cutter carrier 25 is mounted for sliding movement on the frame of the machine, this carrier having a cutter die support 26 pro- 40 jecting upwardly therefrom with a cutter die 21 fixed therein, and-a cutter slide 28 secured to the support for sliding movement thereon in any suitable manner, this cutter slide having a cutter 29 secured therein, as shown in Fig. 3. The wire I4 is projected through the die 21 and through a slot in the slide 28, the cutter 29 operating in connection with the die 21 to shear oi lengthsof wire in a manner that will be readily understood. The cutter carrier is reciprocated in a horizontal plane and the slide 28 in a vertical plane by mechanism now to be described.

A bracket 30 projectsdownwardly from the under side of the carrier 25 this bracket consisting of two side parts, and a carrier reciprocating lever 3| is pivotally attached to the bracket between said side parts as shown in Figs. 5 and 7. The opposite end of this lever is pivotally attached to a crank 32 secured to one end of the shaft |1. A cutter lever 33 is pivotally connected to the lever 3| intermediate the ends of the latter as by means of links 34. The lever 33 consists of two parts pivotally attached intermediate` their ends to opposite sides of the bracket 30, as shownin Fig. 5, the links 34 connecting the two side parts at one end of the lever and a trunnion 35 being pivoted between the side parts of said lever at the opposite ends thereof. A link 36 is secured at one end to said trunnion and its opposite end is pivotally attached to the slide 28, as shown in Fig. 7 of the drawings.

From this construction it will be seen that the carrier 25 and the cutting mechanism has a variable movement gradually increasing and decreasing in rate owing to the crank connection of the lever 3|, this rate being greatest at the instant the crank is traveling parallel with 'a line extending centrally along the lever 3|, and to simplify the description this movement will hereinafter be referred to as being substantially horizontal. The rate of travel of the wire through the machine is xed to be substantially the same as the rate of movement of the cutter mechanism at the moment just referred to and the cutter mechanism is arranged so that the cutting of the wire will take place at this time and when the wire andv cutter mechanism are traveling at substantially the same rates of speed so that there will be no crowding of the Wire or cutters against one another and the cut lengths of wire will kbe permitted to drop free just as soon as severed. 'I'hev carrier V25 is mounted on rails 60 and is retained thereon by means of guides 6| as shown in Fig 8 of the drawings.

It will be noted at this point that the cutter mechanism is operated intermittently to effect its function, including that of severing the wire, the latter moving continuously, and when the cutting mechanism is at rest. This intermittent operation is obtained by an intermittent operation of the shaft |1 that is effected by means of a clutch 31 of the one revolution type, that is, which automatically stops operation of the -parts connected thereby upon a completion of one revolution. 'Ihe clutch shown is also of the roller clutch type but as such clutch structure comprises no part of the present invention and as its construction and operation is readily understood by those skilled in the art a detailed illustration and description are omitted herein and the clutch is designated generally by the numeral 31. Its operation involves contact of a nose 39 with a fixed stop 38 and the brake 22-23 hereinbefore referred to is for the purpose of slowing operation at this time to avoid shock and disastrous results which would otherwise occur by the blow of the nose 39 against said-stop.

Control of the clutch is effected by means of a target interposed in the path of movement of the end of the wire and connected with said stop 38 to operate the latter and remove it from beneath the nose 39 on the clutch, whereupon the latter immediately acts to start operation of the shaft |1, which operation will cease automatically upon completion of one revolution of the clutch as hereinbefore explained. The mechanism connecting the target and the clutch is constructed and. operated as follows: A wire receivlng lframe is positioned ahead ofthe main frame -to receive the cut lengths of wire hereinbefore referred to, this wire receiving frame, briefly described, comprising a base 40, supporting posts 4|, and a table 42 upon the latter of which cut lengths of wire are received and from which they are automatically discharged in a manner well known in machines of this kind and for which reason a detailed illustration and description are omitted herein.

The target hereinbefore referred to comprises a block 43 slidably mounted on the table 42, or in a trough therein and is connected by a rod 44 with a trip slide 45 mounted for reciprocating movement in a guide groove 46 in an extension 41 comprising a part of the wire receiving frame, as shown in Fig. 4 of the drawings. The rod 44 extends through the slide 45 and is adjustably attached thereto as by means of a set screw, as shown in said Fig. 4. A trip 48 projects from the upper side of the slide 45 for contact with a trip block 49 pivotally mounted on a swinging arm 50 suspended on a support 5| projecting from one of the posts 4|. The block 49 is pressed downwardly as by means of a spring plunger in a box 52 secured to the arm 50, and a stop 53 projecting' from said arm limits swinging movement of the block 49. There are two of the arms 50 and supports 5| at the upper ends of the posts 4| at opposite ends of the wire receiving frame and they are operatively connected by a wire 54. The arm 50 at the opposite end of the frame from that bearing the trip block 49 is connected by a rod 55 with a rocking lever arranged on the main frame and comprising lever arms 56--51 secured to opposite ends of a rock shaft 58 as shown in Figs. 3 and 5 of the drawings. The arm 51 is connected by a rod 59 with the stop 38 for the clutch hereinbefore referred to and operates to remove the stop to effect operation of the shaft |1 and -parts connected therewith upon contact of the end of the wire |4 with the target 43 hereinbefore described.

During the operation of the parts just described the end of the wire striking the target 43 moves the latter andthe trip slide 45, carrying the trip 48 against the end of the block 49, this effecting swinging movement of the arms 50 and a pull upon the rod 55 which operates through'the connected mechanism to disengage the stop 38 from the nose of the clutch thereby effecting operation of the clutch to rotate the shaft |1 and operating the mechanism connected therewith including the cutter mechanism to sever the wire. As the trip 48 moves to the right from the position shown in Fig. 4, the block 49 being 'carried by the arm onthe arc of a circle said block travels upwardly until it disengages from the trip 48 and the latter thereupon moves rearwardly independently of said block. Upon release the block 49 and the levers 58 returnV to their former positions and through the connecting wires and rods the stop 38 is positioned in the path ofthe nose 39 `of the clutch to effect disengagement'of the latter upon the completionof its revolution.

Resetting ofthe trip devices-hereinbefore mentioned is effected by means of a resetting arm 62 projecting-from a resetting slide 63 mounted in a slidewayf64 in the extension 41, as shown. in Fig. 4. The slide 63 has a roller engaged in a notch in a'resetting block 65 fast to the top of a resetting lever 66 pivotally mounted at its lower end on the base 40 and pivotally connected at its upper end by a resetting rod 61 with an inter-- mediate lever pivotally mounted on the base 40 and comprising arms 69-10 secured at opposite ends of a. rocker 1I pivotally mounted in a bracket 12 on the base 40, as shown in Figs. 4 and 5. The arm is connected by a bar 13 with a crank pin on a gear 14 rotatably mounted on a standard 15 mounted on the base of the main frame and meshing with a gear 16 fast to the shaft I1, as shown in Fig. 5. From this it will be seen that the resetting mechanism is actuated intermittently by a like operation of the shaft I1. In order to regulate the movement of the arm 62 relative to that of the trip slide 45 a contact 11 is formed as a head on the end of a sleeve 18 threaded into the arm 62 whereby adjustment of the contact relative to the trip slide 45 may be had, a set screw as shown in Fig. 4 being employed to hold the stop in any position of adjustment and the rod 44 extending through the sleev to permit movement of said sleeve independently of saidl rod.

As an aid to a full understanding of these machines by those skilled in their use some parts are shown without specific reference thereto. As an instance, a cam 19 on the shaft I1 is connected with a shaft 80 which through a link connection 8| and connecting rod 82 operates to discharge the cut lengths of wire from the table 42. Other parts are similarly shown but a description is omitted herein as not necessary to an understanding of the invention.

While the target 43 is shown and described herein as a means directly acted upon by the wire for controlling the clutch mechanism, it will be obvious that the trip slide 45 may serve this purpose, and wherever the word target is used in the description or claims herein it is considered to refer to either of said members, the target 43 or the trip slide 45.

The gears -14 and 16 are of such relative sizes and the crank connection of the rod 13 is such as to impart gradually increasing and decreasing rates of movement to the arm 62, this movement being such as not to interfere with or restrict movement of the trip slide 45 but to effect movement to engage the slide at the proper time to eiect resetting movement thereof.
