MACHINE FOR AND METHOD OFWEAVING COILED-WIRE FA BRIC.

ESPBCIFICATION forming part of Letters Patent No. 511,435, dated December 26, 1893.

Application filed September 8,1892. Serial No. 445,383. (No model.)

To ttZZ whom it may concern:

Be it known that I, CYRUS KEHR, a citizen of the United States, residing at Lakeside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in-Machines for and Methods of Weav-' ing Coiled-Wire Fabric; and I do hereby declare 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, reference being had to the accompanying drawings,

and to letters of reference marked thereon,

which form a part of this specification.

My improvement consists in certain additions to and improvements of such machines and methods as are described in Letters Patent of the United States No. 348,150, granted to Orlando P. Briggs, August 24, 1886; No. 480,007, granted to O. P. Briggs and F. LJBryant, August 2, 1892; and No. 463,993, granted to me November 24, 1891. My improvement is also applicable to what are termed hand machines; namely, machines in which the coil-forming mechanism is operated by hand and the fabric is formed upon a table and shifted and controlled by hand upon said table and the coils are cut by hand. In other words, the mechanism involved in my improvement is to be so geared as to operate automatically in conj unctionwith the coil-forming mechanism. Whether the remainder of the work is performed automatically, is immaterial so far as my improvement is con- 35.

cerned.

What is termed coiled wire fabric is formed by pushing the wire through a'spiral passage, whereby it is formed into a spiral, to a sufficient distance to form the length of the fabric, and then cutting off the coil and forcing more wire through the spiral passage and causingth e second coil to intertwine with the first at each turn, then cutting the second coil and forming a third and ,causing it, while being formed, to intertwine with the second." Heretofore, in the insertion of the new or in-coming coil into the last-finished or marginal coil of the fabric, the strength of the wire of which the coil has been composed has been solely relied upon to effectthe pro- .same machine.

, gression of the coil and devices designed to keep the coil in the proper'course to intertwine with the marginal coil were relatively stationary and therefore passivein character and dependent for effectiveness upon the strength of the coil. It has been found that friction and the flexibility and pliability of the wire' prevent this method from being perfect. The unavoidable variationin the pitch of the coils is also an element operating against the success of this methodyfor, if

the incoming coil differs in pitch from the marginal coil, the end of the iii-coming coil will meet the turns of the marginal coil or any faces of parts of the machine concerned in holding and shifting the marginal coil and be deflected or stopped thereby.

According to my improvement, the end of the in-coming coil is engaged and guided or led through its proper path. By this method the insertion of the new coil is not dependent upon the strength of the wire, but upon the operation of the mechanism employed in engaging and leading the forward end of the coil.

Theessential part of the apparatus for practicing my improved process may be the path to be traversed by thein-coming coil and then made to engage the end of the incoming coil and travel synchronously with the latter from the coiler spirally through the turns of the marginal coil.

The accompanying drawings show my improvement applied to such a machine as is illustrated in said patent to Briggs and Bryant, No. 480,007.

In said drawings, Figures 1 and 2 constitute a vertical sectional view of the machine, the machine being of such length as to require two sheets for one view. Figs. 3 and 4' constitute, in a similar manner, a plan of the Fig. 5 is a vertical section in the line a-b of Fig. 3 looking in the direction of the arrow. Fig. 6 is aplan of the coilforming mechanism. Fig.7 isa detail of the rolls andguides concerned in forcing the wire through the spiral passage. Figs. 8, 9, and 10 are details of the needle, coils, and; knife.

Figs. 11 and 12 show alternative means for 100 termed a spiral needle, which is inserted into rotating the needle. Fig. 13 shows a detail of the mechanism for reciprocating the marginal coil longitudinally.

In said drawings, A is aframe upon which the operative parts of the machine are supported. Said frame is a little more than twice as long as the length of the fabric to be woven.

A is a horizontal carriage supported by wheels, A arranged at each corner of said frame and resting in ways, A fixed upon the frame, A, parallel to the length of said frame. The same result may be obtained by applying the wheels, A to the frame,A, and the ways, A to the carriage, A. The object of said wheels and ways is to provide a limited longitudinal reciprocation of the carriage, A, as and for the purposes hereinafter set forth.

B is a band-wheel mounted loosely upon a driving-shaft, B, which shaft is supported in bearings, B suitably located upon one end of the frame, A.

B is a bevel-gear loosely surrounding the shaft, B, and secured to the wheel, 13, and B is a bevel-gear meshinginto the bevel-gear, B and surrounding and keyed to the worm-shaft, B which worm-shaft engages the worm gearwheel, B and imparts rotation to the latter. The worm-gear, B surrounds and is keyed to a horizontal shaft, B and uponsaid shaft, B at one side of the worm-gear wheel, B and keyed to said shaft, is a spur-gear, 13 meshing into a small spur-gear, B mounted upon and keyed to the horizontal shaft, 13 Surrounding the shaft, B is a cam-wheel, B, provided with two cam-faces, Z1

B isa clutch-lever pivoted between its ends,

as at 12 and having its upper end in engagement with a clutch, 13 which is keyed to the shaft, 13', and adapted to engage the bandwheel, B, so that motion may be transmitted from said band-wheel to said shaft, B. The relation of said band-wheel, clutch-lever, B and cam-wheel, B is such that when the clutch, B is thrown into engagement with the band-wheel, B, the lower end of the arm, B, will be in the path of the cam-faces, b, and ready to be moved by the latter when they pass said end. The said clutch is held normally in engagement with said band-wheel by an expanding coiled spring, B (See Figs. 4. and 6.)

From the foregoing it will be seen that if the band-wheel, B, is rotated continuously the gears, B B worm-shaft, B worm-gear, B, shaft, B spur-gears, B and B shaft, B

and cam-wheel, B, will be operated continuously, while the clutch-lever, B clutch, B and shaft, B, will be operated intermittently, and that the interval during which the shaft, B, rotates will hold the same ratio to the interval during which it does not rotate as the ratio of the spaces between the cam-faces, b, holds to the length of said faces. For example, if the length of each cam-face is only onetenth of the space between the two cam-faces, the interval during which the shaft, B, does not rotate will be only one-tenth as long as the period during which it does rotate. The object in providing these continuous and intermittent movements is to afford means for periodically arresting the action of the coilforming mechanism and at the same time provide continuously-moving parts which may be treated as a source of movement for other portions of the machine which are to operate during thesuspension of the operation of the coiling mechanism.

For convenience, the coil-forming mechan ism will be termed the coiler. This is designated by the letterC. As any suitable form of coiler may be used in connection with the other parts of the machine, and as a variety of coilers are alreadyknown to those familiar with this art, it is deemed suflicient to herein describe one of said coilers as to merely its general features. From the base, 0', rise four bearing-posts, each of which has extending from its upper end-downward through its middle a space in which are the bearingblocks, 0 Said bearing-blocks, 0 form bearings for the horizontal parallel shafts, C and 0 O designating the lower of said shafts and C the upper of said shafts. Said shafts are geared to each other by spur-gears, 0, applied, respectively, to the shafts, G, and 0 O is a spur-gear located upon the shaft, 0, and meshing into another spur-gear, O, suitably supported between the shafts, O, and B, and in turn meshing into a spur-gear, 13, mounted upon the shaft, B. Upon the middie of the shafts, C, and C are located wireforcing rolls, o and c, respectively, which rolls bear upon each other and are turned when said shafts are rotated. The two middle posts, 0 terminate above in arches, C and a vertical screw, 0, extends downward through each such arch and bears upon an expanding spring, (not shown,) which spring in turn bears upon the bearing-block, G located in the adjacent bearing-post, C The lower bearing-blocks, 0 have fixed positions in the lower portions of the channels or vertical spaces in the posts, 0 so thatthe positions of the spur-gears, C, and the wire forcing roll on the shaft, 0 are unyielding. Driving the screw, 0 downward will cause the spring, 0 to press the adjacent upper bearing-block, C downward upon the shaft, C, and said shaft will be pressed down so that the upper wire-forcing roll and the spur-gears upon said shafts will be forced together.

0 is a guide for leading the wires,f, to the wire-forcing rolls, and C is a guide to lead the wire from the forcing-rolls to the coilforming spindle, C Said coil-forming spindle has around it a spiral passage and a shell, The wire is forced through said spiral passage between said spindle and said shell. and is thereby transformed into a coil, which passes off over the end of the spindle, 0 into the channel, D, to be hereinafter de-,

with the spindle, 0 so as to receive the needle, N, and the coil projected from the coiler, C, and at the side of said channel is a wall, d, to aid in retaining said coil and needle.

D is a roller mounted upon and extending lengthwise of the frame, A, at the rear of the channel, D, and arranged to be rotated, as will be hereinafter described. g I

D is aroller located above and parallel to the roller, D, and having its journals resting loosely in vertical guide-Ways D so that it will rest by gravity upon the roller, D, or upon the woven-wire fabric, F, when the latter lies between said rollers. The roller, D,

is rotated in the direction indicated by the.-

arrow, and, together with the roller, D serves to draw the coiled fabric away from the line in which the coils are formed.

The shaft, B whichhas alreadybeen described as rotating continuously, has surrounding it rigidly the spur-gear, B Beneath, parallel to, and extending along the entire length of the carriage, A, is a shaft, E, which receives motion from the spur-gear, B through the spur-gear, E, with which it meshes and which surrounds and is keyed to the shaft, E.

At the left end or foot of the machine, a mutilated gear, E surrounds and is secured tothe shaft, E. Said mutilated gear has upon its periphery four equidistant teeth, 6 The roll, D, has at the foot end of the machine a spur-gear, D which is in plane with the mutilated gear, E and of proper diame-v ter-to have its teeth reach into the path of the teeth, 6 of said mutilated gear. The rolls, D, and D may or may not be provided with intermeshing gears like the one shown at D Fig. 4. It will now be seen that with each quarter rotation of the mutilated gear, E the rolls, D, and D will be rotated through a few degrees. The extent of this rotation of said rolls is sufficient to move a point in the circumference of one of said rolls through av distance equal to the diameter of one of the coils of the fabric, the precise distance being attained 'by establishing the proper ratio of difference between the mutilated gear, E and the spur-gear, D tervals between these partial rotations of the rolls, D, and D is dependent upon the velocity of the mutilated gear, E and the gears intervening betweensaid mutilated gear and the band-wheel, B.

In starting the machine, the fabric, F, is managed by the operator until enough has been formed to be properly engaged by the mechanism of the machine.

Then the marginal or last-finished coil is held parallel to and partially in the groove, D, by the pins,

' G, of the pin-bars G, the pins G, one of The length of the insaid pin-bars standing in the coil next to the marginal or final coil and bearing against both of said coils, and the rolls, D, and D tending to draw the fabric away from said pin-bar. (See Figs. 8 and 9.) By this means every marginal coil is brought with great accuracy into the desired relation with the coiling-axis, or the line which coincides with the axis of, the new coil as the latter is being projected from the coiler, so that every turn of the marginal coil is in the precise position best adapted to allow the new coil to intertwine at each rotation with said turn. The groove or channel, D, is'thus in accurate relation with every turn of the marginal coil,

and the needle, N, in being projected through said groove toward the coiler is guided at every turn into precise relationwith each turn of the final coil. As soon as a coil is completed and cut adjacent to the coiler, the pin-bar, G, then in engagement with the fabric must be released, in order that the fabric may be drawn from the coiling-axis by the fabric-drawing mechanism, and at the same time the other pin-bar, G, must be brought .1

the movement of the entire fabric is arrested.

The upper pin-bar, G, is located beneath and has its pins, G, rising through the openings,'g, in the top of the carriage, A. The lower pin-bar, G, is located beneath the upper pin-bar and has its pins, G, rising through the upper pin-bar between the pins, G, of the upper pin-bar and through openings, 9, inthe top of the carriage, A. Each of the pin-bars,

G, has a vertical support G resting upon a cam, G on the shaft, E, the extended portions of the cams which receive the supports from one pin-bar alternating in radial relation with the extended portion of the cams supporting the other pin-bar, so that as the shaft, E, is rotated, the pin-bars, G, are alternately elevated, whereby the pins on the respective bars, G, are alternately extended upward through the top of the carriage, A, into the path of the coils of the fabric, one set of said pins always rising through the top of said carriage, while the other set of said pins is being drawn downward through said top.

G G are depending arms attached by their upper ends to the carriage, A, close to the sides of the pin-bars and serve to so confine the bars, G, as to allow the latter to move only in a vertical plane. (See Fig. 2;) If so desired, such knife-bars as are described in said patent to Briggs and Bryant, No. 480,007, inay be placed upon the machine in proper arrangement to co-operate with the pin-bars, G, as described in said patent.

The mechanisms leading from the shaft,E, to the pin-bars, G, and from said shaft to the rolls, D, and, D are properly timed with reference to each other to producethe necessary simultaneous action.

Attention is now asked to the mechanism for periodically shifting the carriage, A, from and toward the coilert An arm, A extends from said carriage toward the shaft, E, and there supports two rollers, a one extending to each side of the periphery of a cam, J, and each presenting to said cam a face to which the line of movement of the carriage is sub stantially perpendicular. Said cam is duplex, being composed of two disk-form sections, J, each loosely surrounding and separately adjustable upon the shaft, E, by means of setbolts, J and having on the face toward the adjacent roller, a one or more cam faces, j, the cam face or faces" on the one section, J, alternating in radial spacing with that of those on the other section. The sections, J, of the duplex cam, J, are separated suflicicntly to cause each roller to be pressed laterally by the passing. of the cam-face on the other cam-section, so that when said other camface, J, is rotated past the second roller the movement is reversed. Thus the carriage, A, is alternately shifted upon the ways, A, a distance equal to the difierence between the distance betweenr the rolls, a and the thicknessof the cam,J, from the plane of the cam faces at one side of the 0am to the plane of the cam-faces at the other side of said cam. This distance may be varied by shiftin g the cam-sections of the cam, J. The precise path of reciprocation of the carriage, A, may also be varied in location by bodily shifting the cam, J, toward and from the head of the machine upon the shaft,E. The distance through which said carriage reciprocates should be equal to about onahalf the distance between the turns of the coils in the fabric, F, in order that suchturns may always be brought out of the spiral path through which the new coil is projected, to the end that the new coil may run forward in its path and intertwine at each turn with the marginal or last-finished coil without hitting the latter. The radial position of the cam-faces,j, with reference to the shaft, E, is to be so adjusted as to cause upon the stem, N, of the needle, N.

oneof said cam-faces to operate immediately after the operation of the knife which cuts thecoil adjacent to the coiler.

L is the knife for cutting the wire adjacent to the coiler as often as a coil is completed. L is a stationary block through which the coiL passes as it comes from the coiler and against which the coil is cut by said knife, L. Said knife, L, is attached to a vertically-reciprocating bar, L confined abovein a guide, L ,.and extending below through a guide-plate,

better guided to register with the opening in i said block, L. (See- Fig. 10.) The new coil is projected through said opening, Z, and the downward movement of the knife causes the.

shearing of the coil. From a point below the level of the shaft, 13 an anti-friction roller, 1, is supported by said bar, L and extends laterally beneath a cam, L surrounding the shaft, 13 As the extended portion of said cam passes between said shaft, 13", and said roller, 1, the latter and the bar, L and knife, L, are forced downward, so as to out, and when said extended portion is passed out of engagement with said roller, the latter and said bar and knife are allowed to rise in respouse to the expansion of said spring, L The extended portion of said cam, L is so placed radially upon the shaft, B as to cause the knife, L, to operateimmediately after the forcing-rolls of the coiler have rotated a sufficient number of times to project; a coil of the desired length and have stopped.

The needle, N, is shown located uponacarriage, O, which carriage is supported by the frame, A, at the end of the. latteroppositethe coiler, O. Said carriage, 0, is arranged in horizontalways, 0', extending lengthwise of the frame, A. The needle, N, has astem,N, resting in bearings, n, axially in line-with the coiling-axis. From this stem the needle extends toward the coiler a distance equal to the length of the fabric to be woven. The spiral turns of the needle conform in direction, pitch, and mean diameter to the direction, pitch,and mean diameter of the coils to beformed, so that said needle may be rotated and simultaneously movetoward the coiler through the precise pathto be traversed by the in-coming coil. At its free end, said needle is tubular for a short distance, as indicated in Fig. 9, in order that the new coil may enter or telescope with said needle tothe extent of a few turns.

0 is a relatively small gear pinion mounted O is a relatively large bevel gear mounted on a shaft, 0 located upon the carriage, Q,

at right angles to the stern, N, so as to allow the bevel wheel, 0 to intermesh with the pinion, 0

O is a spur-gear mounted on the outer end of the shaft, 0 and meshing into a horizontal rack, 0, extending lengthwise upon the frame, A, beneath said spur-gear. seen that by reason of this arrangement of It Will be gears, rotation would be imparted to the neel cupies.

bodily toward the coiler and at the same time rotated in the same manner that the new coil 1s rotated while being projected through the channel, D; that when the carriage, O, is held in the opposite direction, the needle, N, will be moved bodily away from the coiler and at the same time rotated in the opposite direction. Thus the needle,-N, may be made to traverse toward the coiler through the precis'e path to be traversed by the new coil and then retract through the same path.

The carriage, 0, should rest during a short interval at each end of its range of movement. Then, when the carriage is at its limit of movement toward the coiler, the needle, N, is resting in proper position to receive the end of the new coil, as shown in Fig. 10. The needle should be thus at rest until the incoming coil has progressed sufliciently to enter the needle. It should then start and move away from the coiler synchronously with the new coil. Then, when the carriage is at the other limit of its movement and the needle has been entirely retracted from the fabric, the needle and carriage will remain stationary long enough to permit the cutting of the wire by the knife, L, and the shifting of the fabric on the pins, G, and the longitudinal shifting of the carriage, A. This period of rest may, however, be avoided by retracting the needle farther than is necessary to disengage it from the fabric and'then returning it, the cutting and shifting above mentioned being effected during thetime in which the needle is out of the range of the fabric.

Various means may be employed for controlling the carriage, O. In the drawings, I illustrate the bevel gear, P, mounted upon a shaft, B and meshing into a bevel gear, P, on a vertical shaft, P having suitable bearings in the frame, A, and hearing at its upper en'd beneath and between the ends of the ways, 0', toward the coilera sprocket wheel, P Beneath and between the opposite ends of the ways, 0, is a similar sprocketwheel, P mounted on a vertical shaft, P also having suitable bearings in the frame, A. An endless sprocket chain extends around the sprocket wheels, P and, P in a horizontal plane. Above a portion of the chain, P, at each side of the sprocket wheels, P and, P", the carriage, O, has a depending lug, 0, extending almost to said chain. chain is a lug, p resting in ahorizontal plane of the lug, 0. Since the shaft, B has continuous motion, it follows that the sprocket chain, P, must have continuous motion and that the carriage, 0, must move whenever the lug, 10 is in engagement with one of the lugs, 0, the direction of the movement Of'SEtld carriage depending upon which side of the circuit of the chain the lug, pflat the time oc- -thenext new coil.

Upon said In Figs. 1 and 3, the lug, pflisshown in contact with the lug, 0, at the side of the latter toward the coiler and drawing the carriage away from the coiler. An inspection of Fig.8 will show that the lug, 19 will soon be carrying said ways out of engagement with the lug, 0, and around the wheel, Pflinto the path of the other lug, 0. Between the time of the disengagement fromthe first lug, 0, and the engagement with the other lug, 0, the carriage is at rest, and the coiling, cutting, and fabricshifting mechanisms are so timed as to operate during this interval. As soon as the lug, 10", engages with the second lug, 0, the carriage, O, is set in motion toward the coiler, and the needle is again inserted into the last-finished coil and through the channel, D, to receive In going around the wheel, P the lug, p, is disengaged from the lug, 0,

t at that side of the carriage and subsequently re-engaged with the log, 0, at the other side of the carriage. Thus an interval of rest is afforded during which the coiler may be started and a new coil driven into the tubular end of the needle, N, before the needle is retracted.

The sprocket chain may, obviously, be replaced-by any other form of endless band, but I recommend the sprocket chain as being more precise in its operation.

It is to be noted,that the needle, N, may be made of a relatively thick and rigid wire, so that there will be little tendency for the free end thereof to depart from the true path on being inserted. At the time of retracting, the entire needle is intertwined with-the lastfinished coil and cannot depart from the proper path, and'because the forward end of the new coil is engaged by the end of the needle, such end of the coil must follow the latter through the proper path.

In Figs. 11 and 12, I show alternative means for rotating the needle asthe carriage, 0, progresses; In each case the stem, N','ofthe needle is mounted in bearings, n, as shown in Fig. 3, but the gear wheels, 0 and, 0 are omitted. In Fig. 11, a block, Q, is located toward the coiler and provided with a stationary passage, q, conforming to the diameter and pitch of the needle. Throughthis passage the needle extends. When thecarriage, O, is reciprocated, thev needle is forced through said block and rotated. In Fig. 12, a block, R, is located at the opposite endof the ways, 0', and the stem of the needle is extended through a stationary grooved passage, r, in said block and has its stationary groove to conform to said passage, 1'. It will be readily seen, that the reciprocation of the carriage, 0, will involve the rotation of the needle by the passage of said extended part of the stem through the block, R.
