MACHINE FOR WEAVING CFOILED-WIRE FABRIC.

SPECIFICATION forming part of Letters Patent No. 463,993, dated November 24, 1891.

Application tiled February 16, 1891. Serial No. 381,630. (No model.)

. full, clear, and exact description of the invention, such as will enable others wskilled in they 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.

This invention relates, particularly, to the weaving of coiled-wire fabric for bed-bottoms and similar purposes, such fabric consisting of parallel longitudinal interlinked spiral wire coils.

The object of my invention is to render unnecessary the longitudinal shifting of the fabric after each new coil has been made. Heretofore it has been the custom to shift, either manually or mechanically, as much of the fabric as has been woven longitudinally toward the coiling-machine a distance equal to the distance traversed by the wire of the coils in making a half-turn and after the completion of the next coil to shift the entire fabric away from the coiler the same distance. The coiling-machine is usually arranged at one end ofa table and the fabric formed upon such table by projecting the coils from the machine horizontally over said table, each new coil being made to intertwine at each turn with the last preceding coil, the coils already made being shifted back and forth by the hand of the operator. In a few machines the table or equivalent part supporting the fabric is arranged to be shifted back and forth toward and from the coiler by automatic mechanism. Such a table or supporting apparatus must necessarily be as long as or longer than the fabric, which is usually six feet, and such table and the mechanism thereto connected and the fabric form a heavy and awkward loadto reciprocate. In my improved apparatus the weaving-machine is of itself of such construction as to avoid the necessity for this longitudinal reciprocation of the fabric. In this class of machines the wire is coiled by being forced through a spiral die or passage, and

such passage is made so accurate that the wire projected therefrom travels continuously forward in the same path, so that if suicient wire for one length of coil of the fabric be projected from said coiler and the ooiler stopped and the wire cut at the proper length and the coiler Vagain started the new coil of Wire now driven forward will go in exactly 6o the path traversed by the wire just cut oif, so that it cannot proceed over the length of the fabric without at every turn meeting the wire of the last coil, notwithstanding the fact that the last coil has been shifted laterally. The work can progress only by so shifting the finished coillongitudinall y as to bring every porf tion of it out of the path in which it was //l formed. If the coil be merely shifted laterally away from the coiling-axis a sufficient 7 distance to allow for the intertwining of the next succeeding coil, the coil so shifted will at every turn cut or almost cut through the path in which it was formed. The foregoing is the condition, because the coiling-path i constant as to location. By myimprovernent the radial relation between the last-completedA coil and the coiler is changed after the completion of one coil and before the beginning of a new one.

S is a section in line c e of Fig. 3,1ooking to- 9o ward the right. Fig. 9 is an end View. Figs. 10,11, and l2 are detail views of the cuttingknives.

For conveniencein description the portion of the machine at the right in Figs. l, 2, and 3 is called the head of the machine, while the portion at the left is called the foot of the machine, and for the same reason an imaginary line, of which the axis of the coiling mechanism and the axis of the path ioo through which the wire being coiled is pro# jected form a part, is called the axis of the machine. The portion of said line extending through the path traversed by the wire after entering the coiler is also called the coilin gaxis.

A is a table which forms a support for the mechanism.

A' is a support rising from the head end of the table, and A2 is a similar support rising from the table between the ends of the latter. Said supports terminate above in bearings a a2, respectively. In said bearings rests a rotary frame B, having trunnions b b2, extending through the bearings a a2, respectively.

B is a lever rising from the frame B, and B2 is a rack arranged at the side of the lever B in a plane perpendicular to the axis of the frame B and having two notches B2 ninety degrees apart and of suitable form to alternately receive and hold the reciprocating bolt B, supported by said lever. By means of this lever and rack the frame B may be given a quarterrotation upon its axis and secured at the end of such quarter-rotation.

C is the ceiling-spindle resting with its axis coincident with the coiling-axis and clamped between the parts C and C2 by one or more bolts C2, the part C and the seat of the bolt or bolts being stationary upon the frame B and the part C2 being relatively movable. A passage OL extends between the parts C and C2 in the axis of the frame B to the coilingspindle C, and thence spirally around the latter toward the fabric supporting rollers. These parts constitute the coiler.

D and D are wire-feeding rolls located near the rear end of the coiling-spindle at opposite sides of the axis of the machine, and the same are supported, respectively, by shafts D2 and D3, arranged transversely in the frame B, and the former is supported in the sides of the said frame, while one end of the latter is preferably supported by the curved arm D4, extending inward from the side of the frame. Since this coiler has its axis coincident with the coiling-axis, it has, while at rest, a certain ra-A dial relation to the coiling-axis, and when the support of the coiler is turned upon its axis that radial relation is changed; and the rolls D and D being located at opposite sides of the coiling-axis while the support of their shafts is at rest, they sustain a certain radial relation to the coiling-axis, and when said support is turned upon said coiling-axis said rolls are turned bodily around said coilingaxis and that radial relation is changed. At one side of said rolls spur-gears D5 and DG are located, respectively, around the shafts D2 and D3 and intermesh, so that if either of said shafts is rotated the other must also rotate. From a point near said rolls a hollow shaft D7 extends toward the head of the machine through and beyond the trunnion b', concentric to the axis of the machine and supports a loose wheel DS and the feathered clutch D, arranged to engage said loose wheel. The front end of the shaft D7 is secured to a skew bevel-gear D10, having an open end and meshiu g into another skew bevel-gearD, mounted upon the shaft D2 or D3.

E is the wire to be coiled. This enters the head end of the hollow shaft D7 and passes forward through the latter and the wheel Dl" and between the rolls D and D into the passage C4. The wheel D8 is rotated continuously by means of a belt d8 or otherwise; but since it is loose on the shaft D7 the latter will not be rotated by the wheel D8 without the aid ofthe clutch D. Since the latter is feathered upon said shaft, it cannot be rotated without also rotating the shaft D7, but said clutch may be shifted forward and rearward upon said shaft into and out of engagement with the wheel DS. lVhen it is desired to drive the rolls D and D so as to feed the wire E forward through the passage U4, the clutch D9 is thrown forward into engagement with the wheel D8, so that the latter in rotating will rotate said clutch and the shaft D7 and the skew-gear D1, and the latter will rotate the skew-gear D, shaft D2, roll D, gears D5 and D, shaft D2, and roll D. The wire thus forced through the passage C4 is formed into a spiral coil in the well-known form, and said coil is projected forward a distance equal to the length of the fabric to be woven.

Any suitable means may be employed for shifting the clutch D9. In the drawings I show an arm F extending downward from said clutch to a transverse horizontal rockshaft F', from which the foot-lever F2 extends forward a convenient distance to the side of the machine at which the operator is to stand. A spring F3 is connected byone end to arelatively-fixed portion of the machine and by the other end with the rock-shaft F', the arm F, or the foot-lever F2 (as shown) in proper relation to normally raise said foot-lever and throw the arm F and said clutch rearward, so that said clutch is normally out of engagement with the wheel D8. By this arrangement the coiling mechanism is normally at rest and will operate only while the operator presses the foot-lever F2.

A portion of the frame B, as one of the sides of the latter, may be extended above the axis of the machine a convenient distance, and some yielding part made to bear down upon said part so extended in order to aid in effecting the quarter-rotation of the frame B when the latter is turned suiiiciently to bring.r said raised part over the axis of the machine. The drawings show for this purpose, a yoke G surrounding said frame and bearing upon the upper portion of the latter and having joined to its lower portion astrong spring G', whose lower portion is secured to the table A. Said spring draws downward upon said yoke, and whenever the frame B is rotated more than one-half of the quarter-turn the part of said frame upon which the yokeG bears passes over the axis of the machine, and said yoke then draws downward upon said part of the frame and shifts the latter to the reverse position. By this means the operator need only draw the lever B until the frame has been rotated alittle more than onc- IOO IIO

ilO

half of the quarter-turn and thereafter the yoke G and spring G will complete the movement of said frame, and when such movement is completed such yoke and spring will continue to draw on that side of.the axis of the machine and aid in retaining the frame B in position. Rollers g g may be placed upon the frame B between the latter and said yoke to reduce friction when said frame is turned. It will be seen that if the spring G is made strong enough the lever B need not be provided with the locking-bolt. It is also to be noted that the spring G may be omitted altogether.

The mechanism thus far described is suflicient for making the fabric if the latter is formed upon the ordinary stationary ceilingtable and shifted laterally by hand. I have, however, devised an automatic rotary mechanism for supporting and giving movement to the fabric in a direction at right angles to the axis of the machine, and the same will be next described; but it will be understood that other mechanical means forthis purpose may be used in lien of those which I describe.

H and H are tinted rolls located in a horizontal plane a short distance above the axis of the machine and parallel to and so near each other as to engage the finished fabric E when the latter is passed between said rolls. roll H is supported at its ends by standards H2, rising from the table A, and the roll H is supported in a similar manner by standards The two rolls are made to operate in unison by means of intermeshing spur-gears H4, located upon the. foot end of said rolls, so that if one of said rolls is rotated by extraneous means the other roll must also rotate, but in a direction reverse to that in which the other roll is rotated. Vhen these rolls are arranged above the coiling-axis, as herein described, they must rotate so that their opposing faces will rise, in order that the fabric may be raised from thev axis of the machine. I have devised mechanismby which movement is given to these rolls from the movenient of the frame B. The movement of said rolls is of necessity intermittent and following the completion of each new coil through a suficientpnnmber of degrees to raise the fabric through a distance equal to the diameter of one of the coils E. The head end of the roll H has its shaft or journal extended forward of the standard H3 a sufficient distance to receive a ratchet-wheel I and a double-toothed wheel J. Both of these wheels are xed rigidly upon said shaft. The teeth I on the ratchet-wheel I are directed rearward with reference to the rotation to be given to said wheel and roll. A pawl Pisarranged at the side of the wheel I farthest from the roll H to engage the teeth I and is secured to or a part of a vertical arm I3, which extends downward, and is connected to a horizontal arm I4, extending beneath the forward extension B4 of the frame B and hinged by its opposite end to the table A. The draw- The ings show this as being accomplished by securing two standards A3 to the table in a line parallel to the axis of the machine and at right angles to said arm I4 and extending a shaft A4 from one of said standards A3 to the other and through the end of said arm I4, the latter being loose 011 said shaft. An antifriction roller I5 is preferably placed upon the arm I4 beneath the axis of the machine. The extension B4 of the frame B has on its lower side and above the arm I4 a cam B5, so located as to be directly beneath the axis of the machine when the frame B is moved to a point midway between its two extremes of movement, and said cam extends far enough from the axis of the machine to press upon the anti-friction roller I5 sufficiently to draw the arms I4 and Pand the pawl I2 far enough downward to cause said pawl to turn the rolls H and H the proper number of degrees to move their surfaces through a distance equal to the diameter of one of the coils E. A spring I is located between the arm I4 and the table A and serves to press the arm I4 as far as allowed by the cam B5 and the adjacent portion of the extension B4 of the frame B, and a spring I7 is shown located between the standard H3 and the arm I3 to press the latter toward the wheel I and force the pawl I2 into engagement with 4the teeth I of said wheel.

From the foregoing itwill be obvious that with each shifting of the frame B the rolls H and H will be given apartial rotation and will feed .the wire fabric forward in a direction at right angles to the axis of the machine. To prevent the rolls from turning after they have been given aforward movement by the pawl I2, another pawl Is is hinged by ICO one end to a relatively stationary part, as the standard H3, and the other end arranged to fall behind one of the teeth I upon the instant that the forward movement of the roll ceases. Then any tendency on the part of the rolls to return is stopped by said pawl I8. Said pawl may have a spring l9 arranged to press the free end of said pawl against the wheel I, or said pawl may be extended be; yond its hinge in the direction opposite the wheel I and there provided with a weight 140, which shall tend to tilt the pawl and press the end nearest the wheel against the periphery of the latter. (Both I9 and 110 are shown in Figs. 4;' and 6.)

In addition to the mechanism already described for turning the rolls forward and preventing their return, I have devised means for preventing the rolls from-moving farther than the distance measured by the length of one of the ratchet-teeth I. This I accomplish by a locking mechanism, of which the wheel J forms a part. Said wheel has two sets of teeth J', one set being arranged radially upon said wheel in one plane and the other set being arranged radially upon said IIO radial distance from one tooth to the other being equal to the radial distance through which the rolls H and Il' are to be turned.

J2 is a horizontal shaft located above the wheel J in bearings in the branches h5 of the standard H5, and J 3 is a wheel surrounding and rigidly xed upon the shaft J2 and of sufficient diameter to reach the periphery of the wheel J between the teeth J of said wheel J. Said wheel J5 has radial teethj5 with sufcient space between each two teeth to allow the passage of one of the teeth J.

JA1 is a ratchet-wheel fixed upon the shaft J 2.

J5, JG, J7, and J8 are respectivelyapawl and arms and a friction-roller similar in nature to the parts l2, 1:2111, and l5, the end of the arm J7 opposite the 4arm J6 being hinged to some relatively stationary part-as, for example, the shaft A", to which the arm I4 is hinged, and said pawl being arranged to engage the teeth of the ratchet-wheel J'l and said arm J7 may be kept in its elevated position by a spring J, similar to the spring 15, which keeps the arm l'l in its elevated position, and two coiled springs J10 may each be secured by one end to the rear face of one of the branches h3 of the standard H5 and by the other end to the arm J5, so as to hold the pawl J5 against the ratchet-wheel J '1. The forward extension B" of the frame B has above the anti-friction roller J S a cam B5 of proper depth to cause said anti-friction roller J5 and the arm Jito be depressed sufficiently to cause the pawl J5 to turn the wheel J a radial distance equal to the distance between two ratchet-teeth on said wheel J '1, and said ratchet-teeth are equal in radial spacing to the radial spacing of the teeth j" on the wheel J5. The relation of these parts is such as that one of the teeth j; on the wheel J3 will normall y stand in the path of one set of teeth J on the wheel J and against one of said teeth and the forward side of the latter, while a space between two teeth l75 is in the path of the other set of teeth J. From the foregoing it will be seen that while the wheel J3 is in this position the wheel J and consequently the rolls H and H are locked against forward movement, and that at the same time the pawl I5 prevents backward movement. Thus the said rolls are held rigidly while itis desired that they shall not move, and a forward movement cannot be produced by the pawl l2 until the tooth jg, which is in engagement with one of the teeth J is turned out of the path of the latter. This is accomplished by the pawl J in advance of the movement of the pawl l2. To elfect this prior movement the cam B6 is made so long radially as to throw the anti-friction roller J8 and the arm JT away from the axis of the machine before the cam B5 can turn the anti-friction wheel I5 away from the axis of the machine. To this end the middle of the cam B5 is in line with the middle of the cam B5, but the former extends laterally beyond the cam This is illustratcd particularly in Fig. l of thc drawings, where B5 is seen in front of and smaller than 135. Then the pawl J5 thus turns the wheel J 2, the tooth j, which was in contact with one of the teeth J', moves out of the path of the latter tooth and one of the spaces between that tooth and another is then in line with the tooth J, which was last held, and another tooth j5 is thrown into the path of the other set of teeth J, and the next succeeding tooth of said second set is, upon the next movement of the wheel J, thrown into contact with the tooth js then in the path of the teeth J', so that neither the'momentum of the rolls ll and H nor the momentum or weight of the fabric already woven can turn thc rolls farther forward than the radial distance equal to the diameter of one of the coils of the fabric.

L is a trough, having its bottom preferably rounded on an axis which substantially coincides with the axis of thc machine, and said trough is of a diameter only a little larger than the external diameter of the coils to bc formed. This trough leads from end to end of the rolls lll and H', and its sides are preferably formed higher than the diameter of one coil. (See Fig. 5.) The coil 'is projected from the ceiling-spindle into this trough,and the latter serves as a guide for said coil. Then one coil has been completed, the rolls are turned so as to raise the last coil, so that its lower side will be a short distance above the axis of the machine. Then the next coil will be guided horizontally and laterally by said trough, and at each turn the new coil will intertwine with one of the turns of the last previous coil. By the aid of this trough a very accurate movement of the new coil is insured. Said trough is preferably supported by standards L', arranged at its sides and also intermediate points, if so desired, upon the table A.

lVhile the new coil is being projected through the trough L and the last-finished coil it is desirable that the latter be held firmly against vibration or other movement. To thus hold said coil I have arranged at each side of and above the trough L a presser L2, having a straight edge resting upon the upper side of the last-finished coil. The drawings show a b ar L, journaled in ears L5, rising from the standards L', and the sides of the pressers L2, which are farthest from the axis of the machine, are secured to said bar. Thus said presser is hinged and the weight of the free side causes the free edge to press down upon the last-finished coil and hold the latter in place while the new coil is being formed. The pressure dueto the weight of the presser maybe supplemented byanysuitablenleansas, for example, a screw .l 15, extending through an arm L5, projected outward from the bar L5, said screw being arranged to press upon an adjacent portion of the standards L or the table A. As will be seen from an inspec- TOO IIC)

tion of the drawings, the space between the free edges of thc pressers Ij2 is less than the diameter of the coils e; but. as said pressers are yielding their edges will separate sufficiently to allow the last-finished coil to rise between them when the fabric is shifted by the turning of the rolls I-I and Il.

L7 is a knife secured datwisc to the rear end of the trough L and extending above the bottom of the latter and almost to the axis of the machine and having a cutting-edge at each side substantially radial to the axis of the machine and separated from each other a little less than ninety degrees. Upon the front end of the forward extension B4 of the frame B are secured two knives B7, such knives being arranged in a plane parallel to and incontact with the face of the knife L7, and said knives B7 having cutting-edges directed toward each other and substantially radial to the a'xis of the machine and separated a little more than the thickness of the wire. The position of the passage C4 on the spindle C is to be such as to bring the wire E first beside one edge of the knife L7 and on the other side of said knife when the frame B is in its other position, and the position of the pair of knives B7 upon the end of the extension B4 is to be such that one of said knives shall be opposed to and a little away from the edge of the knife L7 by which the wire of the last-made coil is passed, and that the other of said pair of knives will be opposed to and a little away from the opposite edge of the knife L7 which the wire of the last coil has passed and said other edge of the knife L7, the purpose being to always pass the wire between two knife-edges, in order that the wire may be cut as soon as the coilingmechanism is stopped and the frame B turned. These knives are illustrated in detail in Figs. lO, 11, and 12. From the extension B4 a proj ection BS may rise and have extending through it a passage B7 axially'in line with the axis of the machine. This passage will serve as a guide for the coil coming from the spindle C and will serve to direct said coil into the trough L.
