CANE-WEAVING MACHINE.

SPECIFICATION" forming part of Letters'Patent No. 547,449, dated October 8, 1895.

Application and April s, 1895.

To all whom it may concern/.-

Be it known that we, EDWIN H. POWERS and EUGENE A. TELEAIR, citizens of the United States, residing at Michigan City, in the county of La Porte and State of Indiana,

have invented certain new and useful Im-A ducing the diagonal strand into the cane lfabric used particularly in the manufacture of` the seats of chairs, its object being to secure the rapid introduction of such strands in a` uniform manner and by means of an automatic machine of simple construction.

The invention consists of a shuttle having a spiral pirn, to which is communicated a positive rotary motion, and which draws the strand into the interstices of the fabric.

It consists, further, of means for measuring off and cutting the strands into suitable lengths and automatically attaching them to the pirn.

It consists, further, in-means for reversing the shuttle, so that it operates in both directions. A i

It consists, further, in various features and details of construction accessorylto the several principal features above enumerated.'

The standrof the machine is a rectangular frame 1, and may be constructed of gas-pipe, as shown. The fabric to be operated upon is shown at 2 as `it is being passed through the machine and at 2a as it leaves the machine, withone set of the diagonal strands introduced. The fabric is fed tothe machine from a spool (not shown) mounted upon a rectangular shaft 3, carried by blocks 3c 3d, secured to' two of the end legs of the frame. llt is passed upwardlyand over aro1ler3b,journaled in a pair of arms extending upwardly from the end of the frame, and then, being carried the length of the frame, passes between a pair of feed-rollers 4 4, to which an intermittent motion is communicated, as will be hereinafter described, and is thenf wound upon a spool 1lb, journaled in blocks secured tothe two legs at the opposite end ofthe table from that at which the feed-spool is located. The shaft 3a is removably clamped between the blocks 3e 3f, the former of which is fixed in a socket in the block 3c by means of a set-screw 3S, and has a stud 3h for the engagement of a socketin the end of the shaft 3", While the latter is journaled' in theblock 3d and has a rectangular socket for the reception of the end of the shaft. The block Sfis permanently set within its bearing. Vrlhe Ashaft 3a is removed from theframe for changing spools by loosening the set-screw 3g, when theblock 3 will slide back in its bearing, releasing the haft. The block 3f hasv at itsinner end a head to prevent it from sliding in its bearing to release the shaft, and upon the opposite end are mounted a fixed collar 3J', aleather washer 3k, and a loose metal washer 3m. The

outer end of the block 3f has a screw-threaded ICO ' 3m against the washer 3k.

socket, into which is set a screw 3P, which carries a spiral spring 3, which forces the washer The washer 3m is notched for the engagement of the catch 3f, fixed to the post of the frame 1, and is thereby prevented from rotating. The friction between the washer 3k and 3m, or between the former and the collar 35, prevents the too rapid feeding of the fabric from the spool.

The head of the machine is supported by a frame 21, comprising uprights secured to opposite sides ot' the frame and a cross-bar uniting their upper ends. This frame 21 is diagonal to the frame 1, and to it are secured horizontal slide-bars, upon which are mounted the shuttle-carriers. The shuttle consists of the upper and lower members 9 9, between which the fabric to be operated upon is carried.

The pirn for carrying the diagonal strand into the fabric is carried by the shuttle by being` clamped between its two members, is spiral in form, and runs through the fabric, as will be hereinafter described. This pirn is shown at 5 and is made of a round steel rod worked to a spiral form with a pitch to correspond with the mesh of the fabric. Its forward end is pointed that it may more easily find its way through the fabric. It is provided with a central backwardly-projecting stem 5, to which is swiveled a tailpiece 6, having a lateral recess 6l for engaging and holding the strand. The attachment of the tailpiece to the stem is accomplished by providing the latter with a shank b, having an annular groove 5 and socketing the end of the tailpiece to fit this shank. The tailpiece has a transverse aperture adapted to register with the groove and in this is fitted a pin 6, which, entering the groove 5, holds the tailpiece 6 upon lthe shank 5, but allows it to turn freely. The pirn is given a positive rotary motion by the cam action of a pair of notched plates 8 8, located between the two members of the shuttle, their notches S being cf such size and location as to engage the several convolutions of the pirn.

The plates 8 8 are supported by plates 3, extending between the uprights of the frame 2l, and supported, also, by posts S, standing up from a plate 8, secured to the top of the frame 1. r1`he shuttle comprises the two blocks 9 9, the one above and the other below the plates 3 S. rThe faces of these blocks are beveled at their forward ends that they may advance more smoothly and are centrally recessed. lVithin the recess of each block is journaled a pair of antifriction -rollers 15, which bear against the pirn. Bearing or wear plates 9b 9c are secured to the rearward ends of the blocks 9 9, closing their central re cesses and forming internal bearing-surfaces for such blocks. These plates project beyond the faces of the blocks, their adjacent edges being spaced apart only sufficient to clear the plates S S. The pirn is carried forward by the wear-plates 9b 9c bearing againstits rearward end, which is radially flattened to make a bearing-surface of considerable area, so that as the pirn is turned by running in the notches 8 1 its flattened end slides upon the inner faces of the plates 9b 9c and does not leave one of them until after it has engaged the other.

The shuttle-blocks 9 9 are carried by slideblocks 1S 19, to which they are secured by means of trunnions 9 and 16. Wear-blocks 1S 19 are interposed between the blocks 18 and 9 and 19 and 9 and are preferably of brass.

The blocks 18 19 are apertured to slide upon rectangular bars 2() 20, set in the upright members of the frame 21, and are united by means of a U-shaped frame 10, whose arms are of sufficient length so that its bow or transverse portion 10 always extends beyond the end of the supporting-frame 2l. The bars 2O 2O are also prolonged beyond this frame, and the frame 10 has at its outer end loops 10h 10b, adapted to slide upon these bars.

The shuttle is caused to reciprocate by means of a sprocket-chain 11, carried by horizontal sprocket-wheels 12 12, located below the plate Sb. Motion is communicated to the machine by means of a4 drive-pulley 13, mounted upon a shaft 13, journaled in suitable blocks carried by the lower portion of the frame 1, and which carries, also, a beltpulley 13b, from which a belt 14 leads to a pulley 14, mounted upon the vertical shaft 14h, which carries the sprocket-wheel 12.

The sprocket-chain 11 has one of its links (shown in Fig. 17) provided with an upwardly-projecting stud 11. A link-bar 17 is mounted upon this stud and projects inwardly between the two turns of the chain and is in rigid connection by means ofthe set-screw 17 within the tr-unnion or arbor 16, rigidly attached to the shuttle-block 9, thereby communicating the motion of the chain to the shuttle and reversing the latter as the studded link is turned around the sprocket-wheels. The block 9 is caused to turn with the block 9 by reason of the engagement of the pirn with the friction-rolls 15 15 of the two blocks.

The notches 8 of the plates 8 8 terminate at the end of the travel of the shuttle, and the plates 8 S and Sb Sb are recessed, as shown, to admit of the turning of the shuttle. As it turns the tailpiece 6 slides over the surface of the plate 8, and is thus prevented from being accidentally turned.

The shuttle-block 9 is held in proper position during its movement across the fabric by means of the latches 22 23, pivoted upon the opposite sides of the block 19 by means of a pin 24, upon which both are fixed. rThe latches 22 23 are adapted to be thrown down alternately below the block 19 in front of the link-bar 17. The latch 22 is in the form of a. rock-lever. The latch 23 is in the form of a. swinging lever'. A slide-bar 25, having on opposite sides cam-notches 26 27, reciprocates through the block 19, bearing against the top of the latch 23 and the lower side of the inlal ner end of thelatch 22. As the shuttle reaches the limits of its travel, the end of the bar 25 strikes the vertical members of the frame 2l. and is thrust back iu its bearingin the block 19, the cam-notches 26 27 shifting the latches 22 23, so as to'raise the one which was in advance of the link-bar 17, and thus allow this bar to swing around as the'link to which it is attached turns the sprocket-wheel, and to lower the one which was behind the link-bar, so that it will be engaged by it as it starts upon its return across the fabric.

The spool 4b, upon which the fabric is rolled after being operated upon by the machine, is rotated by means of a belt 4d, leading from a pulley 13c upon the shaft 13a to a pulley C upon the shaft carrying the spool, the pulleys 13C and 4C being differentiated in size, so as to secure the necessary slow motion for the spool 4h. lt is necessary, however, that the movement of the fabric through the machine shall be intermittent, as it must be stationary while being operated upon by the shuttle. This intermittent motion is obtained by means of the feed-rollers et sa, between which the fabric is passed after leaving the head of the machine. The roller 4 is driven by means of a friction-clutch 4e, which is of the same form as is used in connection with the strand-feed, as shown in Fig 16, which will be presently described. This clutch is incorporated into the hub of a crank-arm 4f, which is oscillated` by means ofa pitman 4g, leading from a crankpin set in a gear-Wheel et, journaledinasuitable bracket attached to the frame l and driven by a gear-wheel 4J', mounted upon the shaft of the sprocket-wheel12a. The rollers 4 et are connected at one end by intermesh ing gears, as'shown.

The action of the clutch te is so timed by suitably proportioning the gears 4th 4j that the feed-rollers are actuated while the stud ll, by means of which the shuttle is connected with the sprocket-chain l1, is turning about either one of the wheels l2 12, so that the fabric is stationary while the shuttle is operating upon it', and is moved by the feed-rollers while the shuttle is being turned or reversed. The length ot' each step of the fabric feed is controlled by the pointof attachment of the pitman lg to the crank-arm 4f, and as the cane fabric is made with different sizes of mesh it is important that provision be made for varying the feed. This is accomplished by making the connection between the pitman 4g andthe crank-arm 4f of the pinand-slot form, as shown, and in order that the feed may be changed from the side of the machine this connection is controlled by a lever 4ck, pivoted upon the shaft of the spool 4b, its free arm bearing against the vertical l post la, forming a part of the frame l, and is transversely notched or serrated for the purpose of increasing the friction and preventing the accidental shifting of the arm 42k. The short arm of the lever 4k is connected with the pitrnan 4g by means of a link 4P. lt is of advantage that the feedmechanism be under easy control by the operator for the reason that the mesh of the fabric is apt to be irregular, so that the feed needs to be varied a little from time to time.

The material for forming the strand 7 is fed to the machine from any desired source of supply above, which we have not deemed it necessary to show, and is fed to each side of the machine by means of a pair of frictionwheels 26 27, mounted upon and at each end of the frame 2l, the strand 7 being carried downwardly between them, the `faces of the wheels being knurled to increase the friction.

The wheel 27 is carried by a sleeve 27a, mounted upon a stud 27h, having an eccentric stem 27e, which is journaled in a block 2l, mounted upon the frame 2l. A crank-arm 27d is xed to the shaft 27c and its outer end is connected by means of a spring 279with the block 2la in such manner as to tend to draw the wheel 27 downwardly and toward the wheel 26, thereby adapting the feed mechanism to any irregularities in the material while insuring a grip of the strand however thin it may be.V The wheel 26 is carried by a sleeve 26", mounted loosely upon a stud 26C, set in the block 2l, and a two-channel drum 261L is mounted upon4 the sleeve 26b and is provided with the roller friction-cluteh 26d, adapted to lock the drum and sleeve together for rotation in one direction. At 26e is shown a spring for holding the roller 26d in such position in its race that it is instantly engaged when the drum turns against it.

The drums 26a at opposite sides of the machine are united by cords 28 28, each wound oppositely upon the two drums, both with reference to each other and with reference to its own ends. The cord 28 is attached to an arm 29, projecting upwardly from the shuttle--carrier, so that as the shuttle travels it unwinds this cord from one of the drums and, winding the cord 2Sa onto the same drum, unwinds it from the drum at the opposite end, thereby winding the cord 28 onto that drum. The clutches 26d are'so disposed that the wheels 26 are rotated so as to draw the strand 7 downwardly and are motionless when the drums 26 turn in the opposite direction. The strand after passing between the wheels 26 27 enters a guide-tube 30, which leads to a vertical aperture in a reciprocating slide-bar 3l. This bar is carried in a socket 82, from which it protrudes and within which it slides inthe post of the frame 2l and is held within this socket by means of a bolt 32a, set in the frame and projecting into a longitudinal recess 31* in the side ot the bar, thisrecess being of sufficient length to allow of the reciprocation of the bar within the desired limits.

A spiral spring 32b is placed within the socket 32 behind the bar 3l and tends to expel the latter. The aperture of the bar 31 continues IOO IIO

the passage formed by the tube 30, but is contracted approximately to the shape in crosssection of the strand 7. A blade 33 is fixed to the side of the postof the frame Qlimmediately below the socket 32, so as to cutoff the strand projecting through the aperture of the bar 3l when the latter is forced into the socket.. A rod 34 projects in each direction from the shuttle-carrier 18 in the direction of its movement and is adapted for contact with the outer end of the bar 31 as the shuttle-carrier reaches the limit of its travel, thereby forcing the bar within its socket and cutting off the strand 7, which has been fed down. 'It is necessary that the strand thus cut off be held by some form of clamping device until engaged by the tailpiece of the pirn. The mechanism provided for this purpose comprises rectangular rods 35 35, mounted, respectively, to slidein suitable apertures in the wear-blocks 18a 19, parallel with the line of travel of the shuttle. These bars 35 35a are provided at each end with rigidly attached and laterally-projecting arms 36 36, the arms projecting in each instance toward the plates S 8. A spiral spring 37 is mounted upon. each end of each of the bars, being interposed between its lateral arm and the block by which it is carried and being normally under slight tension. At the outer end of each of the arms 36 36a there is a horizontal offset 36h, in each instance projecting across the slot between the plates S 3, within which the pirn 5 travels. The length of the bars 35 35a is such that their lateral arms 36 36'DL come into contact with the vertical portion of the frame 2l before the rod 34 actuates the shears, and they are thereby forced backwardly through their bearings, the springs on the forward ends of these bars being compressed. This action securely clamps the strand 7 between the offsets 36b of the arms 36 36 and the frame 2l, preventing it from falling when cut off by the shears. A recess 38 is formed in the inner face of the upright portion of the frame 2l to receive the tailpiece 6 of the pirn 5 when the shuttle is reversed for its return movement. The recess 6b in the tailpiece 6 of the pirn is on the forward side as the shuttle turns and automatically engages the strand 7 as the shuttle is brought into its proper position. As the shuttle starts upon its next trip across the fabric the expanding springs 37 hold the arms 36 36a firmly against the frame 2l, and in the meantime the tailpiece of the pirn has traveled with the shuttle and doubled the strand as it has been drawn between the offsets36", so as to secure a hrm grip upon it. The springs 37 having resumed their normal tension, the arms 36 36n leave the frame 2l and the strand 7 is free to be drawn into the fabric by the shuttle. As indicated in Fig. 4, the folded end '7a of the strand 7 is held by the off- Y set of the arm 36, thereby preventing the disen- The aperture in the block 18a, within which the bar 35 is carried, opens to and slightly encroaches upon the socket serving as the bearing for the trunnion 9e. This trunnion has its surface cut by two transverse V-shaped recesses diametrically opposite each other and parallel with the longitudinal line of the block 9 and adapted to receive an angle of the bar 35. The bar 35 engages with the recess in the trunnion 9e, serving as a dog to hold the block 9 steady as it advances. angle of the bar 35, which enters the recess of the trunnion 9e, is provided with two recesses 9c 9, located upon opposite sides of the trunnion and at such distances therefrom that the movement of the bar 35 Within its hub by means of its contact with the frame 2l causes one of these recesses 9c 9d to register with the trunnion-socket, thereby permitting the block 9 to be turned.

XVe are aware that a spiral needle and spiral path-nder or a so-called shed-former for a straight needle have been used for introducing the diagonal strand into cane fabric, such implement or combination of implements being operated by a thrust and being necessarily of a length equaling the diagonal width of the fabric. Such construction necessitates the withdrawal of the needle after the fabric has been crossed or it is necessary to draw this long needle throughthe fabric after the tip of the spiral finder has reachedthe opposite side.

In using the term pirn we intend to distinguish from this long implement and mean thereby a short piece which travels entirely across the fabric, drawing the strand with it, so that when the pirn has once crossed the fabric the operation is complete, the pirn, as herein described, differing from the pirn of a shuttle us'ed in the weaving of textiles only in that it does not carry a supply of the material to be paid out as it advances, but draws the strand after it through the mesh.

Ve believe we are the first to introduce the diagonal strand into cane fabric by the use of a spiral pirn havinga central swiveled tail piece or strand-holder for the attachment of the strand and rotated by mechanical means and that We are entitled to protection in the manufacture, use, and sale of such a device by Whatever mechanism the pirn is rotated.
