BENJAMIN SCARLES, OF CLINTON, MASSACHUSETTS, ASSIGNOR TO THE CLINTON VIRE CLOTH COMPANY, OF SAME PLACE. l

WIRE-NETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,664, dated April 3, 1888.

Application filed December 3, 1886. Serial No. 220,584. (No model.)

To @ZZ wtom it 71mg/ concern.-

Beit known that l, BENJAMIN SoaRLEs, of Clinton county of Worcester,and State of Massachusetts, have invented an improvement in Tire-Netting Machines, of which the following description,in connection with the accompanying drawings, is a specication, like letters on the drawings representing like parts.

' lThis invention has for its object the production of an improved machine by which to automatically manu fact-ure wire-netting.

In the improved machine to be herein described eacli cop-holding tube is provided at its side near its upper end with an opening for the insertion of a cop-of wire, such opening enabling the cop tozbe readily and quickly inserted, the operator retaining the wire at the delivery end of the cop in his hand in position ready to be inserted through the twisting-segment above the tube.

In the manufacture of wire-netting great difficulty has been experienced in producing perfect netting, because of inequality of ten- To obsion upon the bobbin and cop wires. viate such difficulty,the machine has been provided with tension-rolls, one set operating upon all the bobbin-Wires,thus regulating and keeping uniform the tension on all the bobbinwires, and to compensate for the free delivery of the cop-wires as the cops are being unwonnd the cop-holding tubes are provided each with a block having a bulged or convexed f surface against which the wire issuing from the .dro

cop ,is gradually bent more and more, thus adding tension, which counteraets the greater freedom of delivery of the cop as the diameter of the central opening in the cop increases.

The greater the extent of contact between the,

wire and the said bulged surface, which constitutes a compensating tension-surface for the cop-wire, the greater the friction, and so also the greater the diameter of the central opening iu theV cop caused by the withdrawal of the wire the more easily the wire is uncoiled; but as the wire being uuwound from the cop approaches the periphery of the coil it is obvious that the increase of tension made by the increased contact of the wire with the compensating tension surface may be made to counteract any evil which would otherwise be effected by the greater freedom of delivery of -the wire from a cop.

In my invention one of the segments in one of the upper carriages is connected positively to a cop-holding tube, and the said tube in turn is connected positively to a semicircular foot which takes its bearing in a recess in one of the under carriages, the said foot being made instrumental in rotating the lower twisting segment-carrying one of the bobbin-wires.

Other features of my invention will be hereinafter described, and particularly designated in the claims at the end of the specification.

Figure 1, in front elevation, represents a sufficient portion of a machine embodying my invention to enable the same to be understood,

the machine being broken out between the ends to save space upon the drawing, the meshroll being shown partially by dotted lines, some wire-netting being also shown; but the said figure shows but four cop-holding tubes, as they will all be alike. Fig. 2 is a left-hand elevation of Fig. 1. Fig. 2 is a sectional detail in the line w', Fig. 2. Fig. 2b is a detail of part of the frame with the circular plate shown in Fig. 2 removed. Fig 3 is a section of Fig. l in the dotted line x zr, looking to the right. Fig. 4 is a right-hand end elevation of Fig. 1. Fig. 5 is a partial section of Fig. 1, the section being longitudinally through the center of the carriages. Fig. 6 is a horizontal sectional de` tail showing part of the shaft and means for operating one of the carriages. Fig. 7 is a section of Fig. 6 in the line x2. Fig. Sis a section of Fig. 7 in the line rc3. Figs. 9 to 12, inclusive, show details of connecting devices, to be described, instrumental in operating the carriages. Fig. 13 shows two of the carriages moved into a different position from the position shown in Fig. 6 to enable the :ne-Xt mesh 4t0 be twisted. Fig. 14 shows one of the upper The power-shaft A', having suitable bearings, as A2, and driven in any usual manner, has at one end a bevel-pinion, A3, which engages a bevel-gear, A4, on a shaft, A5, having a worm, A, and two spur-pnions, A7 and A8, of like diameter. The worm A@ engages a worm-gear, B, fast to the end or journal of the mesh-roll B', provided with suitable teeth, Bt, herein shown as made of wire and adapted to enter the mesh of the net, the said teeth entering the meshes of the net acting thereon to pull both the bobbin and cop-wires through the twisting-segments a tt b and from the bobbinsf2 and cops g2, to be described.

The worm A6 is herein shown as having a single thread of ordinary pitch; but if a larger mesh should be desired for the netting I may provide it with a double thread, which would enable me to rotate the gear B and mesh-roll at an increased speed, or the worm may be made liner' and left single to correspond with a shorter mesh.

The spur-pinion A7 engages a gear, B3, fast on the camshaft B4 and aids in rotating the said cam-shaft, the latter also having fast on it a spur-gear, B5, which is engaged by the spur-pinion A8, the two spur-pinions operating in unison to rotate the said shaft very steadily and positively, thus obviating any lost motion because of twisting of the shaft, and also preventing torsions of the shaft B4. The shaft B* has fast on it a cam, C, made, as herein shown, (see Fig. 7,) of segmental shape, the said cam in the rotation of the said shaft acting on one and then on another of two fric tion-rollers, c e', mounted upon studs c'Z c",hav ing dovetailed bodies 2, (see Fig. 8,) which are fitted into slots (see Fig. 6) in an ear, C2, attached to or forming a part of the main carriage D, it being herein shown as attached by screws 3 to the Lipper side of the said main carriage. The studs c c are made adjustable as to their position in the said ear C2 by the adjusting-screws 4, the studs when in adjusted position being clamped by the clampingnuts 5. The ear C2 has aslot, 6, at the point where the shaft B is extended through it, so as to provide for the longitudinal movement ofthe said ear and main carriage to which it is attached.

rlhe main carriage D and the cooperating carriage E, arranged in the upper part of the machine, rest at their under sides upon suitable supportingledges, as d, from end to end of the machine. The carriages D and E, at their under sides, have attached to them a plate, as d', having slots, as d2. (See Fig. 9, where the said plates are shown in detail.)

Outside the end of the frame A is a vertical shaft, F, having three bearings, as at F. The

t shaft F has attached to it two slotted cross arms, F2 F3, (see Figs. 1 and 2,) the said arms being shown separately in Figs. 10 and 12.

The slots of the crossarm F2 receive and have fastened in them two adjustable collated studs, d3 d*, which at their upper ends are provided with suitable friction-rolls to enter the slots d2 made in the under carriages, D E.

in the plate d, one attached to the carriage D and the other to the carriage E. The slots of the oross-arm F3 have fastened in them two studs, d5 d6, which are provided with loose blocks 8, (see Fig. 11,) which enter slots dT d8 If desired these rolls and loose blocks may be omitted; but their use is preferred. These studs da d'1 d d6 will be adjusted in the slots of the cross arms to insure for the carriages the necessary movement to insure uniformity of mesh as well as proper size.

The main carriage D is moved, as described, positively by the cam C, and as thesaid carriage is so moved the plate d, attached to its under side, acting upon the stud d3, effects the partial rotation of the shaft F, and consequently the stud d" in the slot of the plate d', attached to the under side of the carriage E, causes the latter carriage to be moved in a direction op posite to that of the carriage D, each moving the same distance. In like manner the studs in cross-arm F3, entering the slots dT d8 in the under carriages, D E, cause the said carriages to be moved in like manner.

Each carriage in practice, as best shown in Fig. 11, is provided with two adjustable stops, d d, which are attached by suitable screws, d, to the said carriages at each side of the end frame of the machine, so that in the move ment of the carriages the said stops strike first one and then the other against the end frame, and are there held while the bobbin and copwires are being twisted together. These carriage stopping devices 0l12 d13 are, as shown, composed of blocks having each a hole at one side of its center, and thereby it is obvious that a quarterturn ofa block will permit of a slightly-different throw of a carriage before a stop meets the end frame.

The Acarriages referred to are provided at their Working-edges (scc Fig. 5) with a series of semicircular recesses, as e, to receive in them twisting-segments a b b' and the foot a of the cop-holding tube g. The segments a and the foot a' are contained, respectively, in the carriages D D', and the twisting-segments b b', respectively, in the carriages E E'.

The twisting-segments b b are in fact short tubes, substantially semicircular in cross-section, each tube having a longitudinal hole for the reception of a bobbin-wire, f, taken from a suitable spool or bobbin, f, free to turn on suitable pins or studs,f3, each tube having suitable flanges (see Figs. 3 and 14) at each end to embrace the edge of the carriage in which it is loosely mounted, the said flanges preventing longitudinal movement of the segment. The twisting-segments I; b derive their movement of rotation by the pressure against them, respectively, ofthe twisting-segn'ientaandthe foot a.

Each twisting-segment b and twisting-segmenta (see Figs. 3 and 14) is provided between its flanges with a semi-gear, 13, the two semigears, when any two segments a b are directly opposite each other, forming, as it were, one

IOO

tro

complete gear to be engaged by the teeth of a rack, m, to be described, such rack in engagement with the said gear effecting one or more rotations of the said twisting-segments,`according to the length of stroke of the said rack. The twisting-segment a, also provided with suitable ilanges to rest above and below the carriage D, has attached to or forming a part of it a compensating tension device, a2, for the cop-wire, the said device being herein shown as a block, to which is secured rigidly, by braz'ing or in other well-known manner, the upper end of the cop`holding tube g, the said tube being extended down to nearly the bottom of the machine, where it is suitably attached to a block, a, forming a part of the segmental foot a', the latter having suitable iianges to embrace the carriage D'. rIhe lower end of the tube is rigidly connected to the foot a', the connection being preferably by means of a pin, as 88.

To enable the tension on all the bobbin-wires fto be maintained uniform, I have provided aseries of rolls, ftffsfl, (see Fig. 3,) between which all the bobbin-wires areled and treated alike. The central rollers, ffbetween which the wires f are led, have their journals 26 extended through slots 24 (see Fig. 2") in a part of the frame-work or a stand bolted thereto, the said journals entering notches in an annular plate, 25, one at each end of the frame, and pivoted on studsfg, held in the frame-work, the frame-work, as shown, having an annular projection, 27, to aid in retaining the journals 26 in the notches of the annular plate 25. These rollers f4 f5 f6 f7 act not only to regulate the tension on the bobbin-wires, but also straighten the said wires, and by turning the annular plates, the serewsf9 being first loosened, the wires may be bent more or less and the tension increased or diminished at will. j

By inspection of Fig. 3 it will be seen that the block connected to the twistingsegment a and extended below the carriage D, to forni not only a compensating tension device, but also a means for the attachment to it of the tube g, is located at one side or eceentrically to the dividing-line of the semi-gear described, such location of the block ai and a corresponding location of the block a enabling the cop-holding tube to be made to rotate entirely about the bobbin-wires extended between the twisting-segments b b without coming in contact with the bobbin-wires, thus obviating any friction which would change the tension on the bobbin-wires.

All the carriages referred to are acted upon at their outer sides by suitable gibs, as h, made adjustable in usual manner by adjustingscrews h', the purpose of the gibs being to keep the meeting edges of the pairs of carriages D E and D E pressed closely together during their sliding movement,notwithstanding wear, the withdrawal of the screws, and with them the gibs, enabling the separation of the carriages sufficiently for the retrieval of the twist ing-segments.

Each cop-holding tube g is provided near its upper end (see Fig. 3) with an opening, g', of suitable size to permit the ready and easy introduction therein of the wire cop 912, the said cop being wound in usual manner, so that the wire is drawn out from the interior of the cop, the cop'being of suitable size to substantially iill the said tube g. By providing the tube with an opening, as described, near its top, the cop may be readily introduced and the delivery end of the wire be retained in the hand oi the operator to be easily inserted up through the block a2 and the hole 10 in the twisting-segment a.

rlhe lower end of the block a2 (see Fig. 3) is provided with a surface of peculiar shapeviz., it has an abrupt convex annular ridge, 89, (see Fig. 17) which is extended into the space between the tapering throat 90 of the block al and thetube g, the said ridge being so shaped and located close to the end of the cop of wire in the tube g, so that as the wire being unwound from the interior of the cop in the tube g approaches the periphery of the cop, where the power. required to draw the wire from the cop is lessened, the said wire will be gradually bent more and more across the said abruptly-convexed surface, thereby putting upon the wire an increased amount of friction to compensate for the more free delivery of the wire from the cop.

I am aware that a cop of wire has been placed in a tube having a conical end with a narrow tube at the apex of the conical end, as in United States Patents Nos. 209,520 and 341,230; but with only a conical surface at the end ofthe tube, as shown in the said patents, it is impossible to automatically vary the tension, as when the surfaces have an abrupt convex annular ridge, as-herein provided for.'

The abrupt convex surface of the block a2 constitutes a compensating tension device, and is of special importance in machines of the class herein described, because by its use it is possible to insure substantial uniformity as to the tension exerted upon the cop-wires,which results in greater uniformity in the mesh of the netting, the said bulging surface also act ing to take out any bends or crooks in the copwire.

It is absolutely essential for the production of good work that the tension on the two sets of wires being united to form the netting, the one set coming from the bobbins]c2 and the other from the cops g2, be alike and uniform and constant, for otherwise the slacker wire, whichever it may be, will be twisted about the more tautwire.

The opening g in the tube gis closed by means of a cover, g, herein shown as made tubular, it being free to be raised by hand above and thus uncover the opening g. The

tube g2 is provided with open slots or spaces, as gl, to enable the operator to see as to the quantity of wire remaining therein, and also to enable him to insert into the tube a pin or IIO other suitable device to lift the cop in case of breakage of wire or for other reasons.

Each twisting-segment a bis provided with a series of teeth, as 13, (see Fig. 5,) constituting a semi-gear or one-half of a pinion, the teeth projecting from the said twisting-segments, when the said twisters are in contact with and practically opposite each other,form ing a full pinion,which is engaged by teeth of a longitudinal sliding rack-bar, m, the recip rocation of which causes the positive rotation in unison of the said twisting-segments, the Wires issuing from the said twisting-segments a b above the carriages D E being at such time twisted together, the number of twists depending upon the number of rotations given tothe said twisting-segments, the number of rotations depending upon the length of the stroke of the rack-bar m.

It is frequently necessary to alter the stroke of the rack-bar according to the number of twists desired in the wire.

As herein shown, the carriages D and E are slotted from their inner edges in the direction of their width throughout their length, the slots so made in the said carriages serving as chambers to receive the semi-gears attached to the twisting-segments a b, the width of the said slots in the thickness of the rail being enough larger than the length of the semigears to enable them to be rotated without friction against the carriages, the shoulders of the said segments retaining them in place in the carriages. The chamber in, as herein shown, the front upper carriage, D, is broad enough to receive and constitute a guide for the rack-bar m, and the front side of the carriage D is slotted, as at 28, (see Fig. 5,) to enable connection to be made between the said rack-bar and the devices employed to reciprocate it, the slot 28 being long enough to permit the rackbar to be moved while the carriages are stationary, and vice versa. The rack-bar m has attached to it by screws m (see Fig. 5) a lug, m2, which is struck first at one and then at its other side by the screws m5 m5, held in ears m5m5 of a slide, G, mounted upon suitable guideways, G, attached to or forming part of the main frame-work. The slide G derives its movement of reciprocation from an adjustable link, G, attached at one end by stud G3 to the slide, and at its other end by a stud, G4, to a crank, G5, suitably secured to and rotating in unison with the shaft B5, before described. The link G2 is composed of three parts, 15 16 17. The parts 15 and 16, at their inner ends, have, respectively, right and left hand threads, which are engaged with screw-threaded projections at the ends of the part 17, (see Fig. 1,) the part 17 constituting a nut, the rotation of which in one or the other direction enables the link G2 to be made longer or shorter to thus enable the crank G5, operating the rack m through the said link G2, to leave the rack in exactly the proper position to enable the contacting faces of the twistingsegments to lie parallel and flush with the contacting faces ot' the carriages D and E, so that` as the said carriages are to be moved, as previously described, in opposite directions, the said twisting-segments do not constitute any barrier to their movement.

While the carriages opposed to each other are being reciprocated in opposite directions by the devices described, it is obvious that the twisting-segments must not rotate, but as soon as the proper two twisting-segments arrive opposite each other in the shifting of the carriages then the rotation of the twisting-seg ments must commence.

To arrest the longitudinal movement of the rack-bar for a sufticient length of time to enable the movement of the carriages to take place, I have provided the screws m5 m5, which are made adjustable in the ears m5 m5, so as to leave spaces between their inner ends, which shall be more or less in excess ofthe width of the lug m2, attached to the said rack, the distance between the points ofthe screws and the lug m2 determining the amount of lost motion between the carriage and the rack. It is obvious that the effect would be just the same were the screws m5 m4 supported by the lug m2 rather than by the ears m5 m6.

In the class of machine herein described the strains are very considerable, and to compensate for wear in the cam C,whi ch operates the main carriage D positively, I have made the bolt G5, which connects the link G2 with the slide G, adjustable in the slot 18 in the said slide. To lessen the number of twists in each mesh,the stud G, connecting the link G2 with the crank G5, may be placed in the hole 19 of the said crank. When the stud G4 is adjusted to occupy the hole 19 of the crank G5 to give a definite length of stroke to the rack-bar, it has sometimes been found necessary to change the position of the crank G5 with relation to the shaft B* driving it in order to preserve correct timing of movements ofthe operative parts. To provide for this the gear B5 (see Fig. 15) is provided atone side with a series of holes, n, which receive in them screws n,'attached to a plate, a5, forming part of a collar, a5, fixed bya screw, n4, to the shaft B4, the loosening of the said screws enabling the gear B5 to be turned either forward or backward the distance of one or more of the holes n, the adj ustment of the gear taking with it the crank G5, the latter, as herein shown, being attached to the gear B5 by screws a5, the face of the said gear being recessed or slotted to receive within it a suitable portion of the hub and arm of the crank G5. The twisting-segments a b will in practice be provided each at its upper side with a removable eye-plate, 30, preferably of steel and of dovetail shape, as shown in Fig. 14, the said eye-plate being easily changed when one has been worn by the wire.

The journal or shaft of the meshroll has attached to it a pulley, H, which receives a belt, H', that is extended over a pulley, H5, fast upon and so as to rotate the take-up roll H3 frictionally, the effective power of the said IfO roj

belt in rotating thesaid take-u p roll being regulated and determined according to the requirements of the netting, being made by means of a tension device composed,essentially,of alever, H5, pivoted at IrlG and provided with a sheave, Hl, the lever having at its opposite end an adjustable weight, H8.

The mesh of the netting may be more or less elongated and the width correspondingly narrowed by increasing the speed of the take-up roll H3 driven by the band.

As herein shown, the rack-bar m is placed in the carriage D and is moved by a crank at the left-hand end of the machine; but I wish it to be understood that I do not desire to limit my invention to locating the said rack-bar in the said carriage, for the rack-bar might be located in the carriage E, and the driving mechanism for the rack might be located at the opposite end of the machine. With the rolls o o in the position, Fig. 6, the carriages will be moved a distance to carry one twisting-segment in one carriage from one to another adj acentsegment ofthe opposite carriage; but by placing the 'said rolls closer together the movement of the carriages may be increased to enable a segment to be brought into line with only each alternate opposed segment, or one segment may be skipped to thus make a larger mesh, the segment so skipped not carrying a wire. The cover for closing the opening g of the tube prevents the cop being thrown out of the said opening by centrifugal action.

Prior to my invention the bobbin-wires used in machines for the manufacture of wire-netting,such as herein described, have been each controlled independently by a separate tension device, such construction requiring constant attention of an experienced operator to produce netting of uniform mesh.

The bulging surface a? herein shown is first shown by me in connection with application Serial No. 209,303, led July 28, 1886, for an improved shuttle for wire,the said surface being claimed in connection with a shuttle.
