As the shed-former is pushed in a diagonal line across the fabric it coils about the several junctures of the warp and weft, forming a shed and passing a strand-carrier between the strands of the fabric and inserting a diagonal strand upon the reverse movement of the strand-carrier; As the shed-former is advanced through the fabric it is preferably pushed through a stationary nut Fig. 1, adapted to engage its spiral turns and impart a rotary motion, thereby causing it to enter the fabric at the proper point with a corkscrew movement and relieving the strandsof the fabric of the strain required to rotate the shed-former. The shed-former and strand-carrier form no part of my present inven tion, and they are fully described in the Letters Patent aforesaid, No. 539,601,to which reference may be had for a more detailed description. In my present machine, however, the shed-former when Withdrawn from the fabric is preferably inclosed in a sheath k, provided on one side with a slot Zto receive an arm m, carrying the strand-carrier and projecting from the outer part a of the reciprocating block,and an arm 11, provided with abearing for the spindle (Z and projecting from the inner part f of the reciprocating block A.

Journaled in the framework 1 is amain driving-shaft 3, carrying a revolving belt-pulley 4, receiving motion through a clutch mechanism 5, suitably connected by a fork 6 with a rocking shaft 7, to which a foot-plate 8 and a handlever 9 are attached, by either of which the shaft 7 may be rocked by an attendant to engage and disengage the clutching mechanism 5. The driving-shaft 3 carries a bevel-gear 10, engaging a bevel-gear 11, which turns loosely on astud held in the frame of the machine, and attached. to the bevel-gear 11 is a spur-gear 12, engaging a spur-gear 13 on a cam-shaft 14, which is placed obliquely to the driving-shaft 3 and carries a cam 15 provided with a camgroove 16, inclosing a cam-pulley carried by a reciprocating lever 17.

The reciprocating lever 17 is pivoted at its upper end to the framework of the machine and is connected near its lower end by a link 18, a reciprocating lever 19, which is pivoted at its lower end to the framework of the machine and is connected at its upper end by a link 20 to a sliding block A, which carries the shed-former b and strand-carrier C, thereby imparting a reciprocating motion to the shed-former b and strand-carrier in a diagonal line across a work-supporting table 22, supported upon the framework 1 and provided with a diagonal groove 23 to form a passage-way for the shed-former in its movement through the cane fabric. The table 22 is also provided with a series of openings 24, arranged on opposite sides of the diagonal groove 23 or passage-way for the shed-former to receive the toothed feed-wheels 25, which are carried upon shafts 26, journaled beneath the table 22 and connected by gears 27 with a ratchet-wheel 28, to which an intermittent motion is given by means of a pawl 29, earried upon a plate 30, which is pivoted concentrically with the ratchet-wheel 28 and is capable of being rocked by means of a link 31, connecting the plate 30 with an arm 32, attached to a vertically-sliding bar 33, which carries an arm 34, supporting a cam-roll 35, which rests upon the periphery of a cam 3e, carried upon the cam-shaft 14, thereby causing an intermittent rotary motion in one direction to be imparted to the ratchet-wheel 2S and the feed-wheels The ratchet-wheel 28 is held from reverse movement l a retaining-pawl 37, pivoted on the framework of the machine and held in engagement with the teeth of the ratchet-wheel by a spring 38. The cane fabric to be operated upon is carried upon a roll 39, supported in brackets ie at the side of the framework, and is carried around rolls 41 and 41 and across the table 22 to a take-up roll 42. The take-up roll '12 is connected by a belt 43 with a pulley 44. on the driving-shaft 3, and the tension of the belt 43 is regulated by a tightening-pulley l5, turning loosely on a stud 46, held in a plate 47, which is ad j ustably attached to the framework of the machine. The shaft of the roll 3% is provided with a friction-wlmel 43, carrying a belt 49, having one end connected to an arm 50, which is attached to the frame of the machine, and its opposite end is connected to an arm 51, carried by a lever pivoted on the frame of the machine and having a tooth 52 engaging a stationary notched plate 53, allowing a tension to be imparted to the friction-lwlt -l.) to restrain the roll 39 from turning.

The tension of the driving-belt 43 causes the fabric to be stretched across the table 22; but it is not sullicient to move the fabric thereon, and the feeding of the fabric is accom plished by the intermittent motion of the toothed feed-wheels 25,which project through the openings 24 of the table and engage the meshes of the fabric, causing the fabric to be fed along with an intermittent motion at the withdrawal of the shed-former and strandcarrier in order to draw a new row of diagonal meshes over the passage-way 23 of the table in position to be engagedby the shedformer and straml-carrier at their next forward movement. As the toothed feral-wheels 25 engage the fabric upon opposite sides of the diagonal groove 23 the fabric is moved bodily over the passage-way for the shedformer, and the strain exerted by the feedwheels upon the fabric is applied equally upon both sides of the passage-way, thereby preventing the meshcs which are to be engaged by the shed-former from becoming distorted.

In case an imperfect insertion of the diagonal strand should occur provision is made for drawing back the cane fabric on the table 22 by means of a-hand-wheel'54 on the shaft of the ratchet-wheel 28 and by interposing a take-up between the table 22 and the takeup roll 42, consisting of a swinging frame 55, pivoted to the framework of the machine at 57 and provided with a rod 58 and a roll 59 parallel with the axis of, the take-up roll 42. The fabric 60 is taken from the'table 22 around the roll 59 and rod 58 to the take-up roll 42.

A spring 62 is inserted between the framework of the maehineand the swinging frame 55, w ith'its tension applied to normally hold an arm 63 of the swinging frame 55 against the framework ofthe machine. The woven fabric as it passes from the table 22 is held in contact therewith by the pressure of weight ed covers, consisting of the triangular plates 64 64, having parallel edges 65 65, separated by-a space 66 suliicient to allow the passage of theshed-formcr. The plate 64 is hinged at 67, and the plate 64 is similarly hinged at'68 to stands supported on the framework of the machine, and the plates are proloom with strings or cords 70 interwoven in its weft-strands onopposite edges of the fabric to form a selvage, which it is desirable to remove before inserting the diagonalstrands, and I accomplish this result by passing one of the cords 70 through holes'in fixed pins or studs 71 and" 71, projecting upwardly from the frame of the machine on each side of the fabric, and the opposite cord 7 O is taken through a guide-plate 72 and stud 71.

From the pins 71 71 the two cords 70 are carried between the two rotating milled rolls 7 3 and 74, by which the cords are taken up as fast as the fabric is'fed along. The milled roll 73 is driven by one of the shafts of the feed-wheels 25, and the milled roll 74 is supported by asliding bearing which is acted upon by a spring 75 to pinch the cords 7 0 between the milled edges of the rolls.

' hen the strand-carrier,with astrip of cane, looped through its eye, has drawn the diagonal strand through themeshes of the fabric, as described'in Patent No. 539,601, the strand is removed from the eye of the strand-carrier by holding the strand from longitudinalmovement while the strand-carrier is completing its return movement by a clamping mechanism consisting of a fixed plate 76, overhanging the path of the strand-carrier and extending over the upper end of a clamping-bar 7 7 capable of a vertical sliding movement, by which the strand is clamped between the end of the clampingbar and the fixed plate 76. The clam pingbar 77 is moved upward at the proper period to seize the diagonal strand by means of a lifting-bar 81, having a vertical arm 82 capa ble of sliding in fixed ways, and a horizontal arm 83, provided with a forked end, inclosing the clamping-bar 77. The vertical arm 82 of the lifting-bar is provided with a vertical slot or mortise 84 to receive the end 85 of a link 86, pivoted at its opposite end 87 to an arm 88, attached to the reciprocating lever 17, by which the link 86 is given a reciprocating movement through the mortise 84 of the lifting-bar 81. The link 86 is provided on its upper side with a projection 89, having on one side a vertical surface and on its opposite side an inclined or cam-shaped surface 91.

Pivoted to the lifting-bar 90 and within the mortise 84 is a curved latch 92, with its lower end extending into the path of the projection 89 and having its upper end provided with a shoulder 93, which is normally held against the lifting-bar 81 by means of a spiral spring 94. As the link 86 moves forward in the direction of the arrow the vertical wall 90 of the projection 89 strikes the latch 92 and rocks it upon its pivot, thereby allowing the projection 89 to pass the latch and allow it to be returned to its normal position by the action of the spiral spring 94. Upon the return movement of the link 86 the cam-surface 91, acting against the curved end of the latch 91, serves to raise the liftingbar-81. Between the forked end of the horizontal arm 83 of the lifting-bar and the shoulder 78 on the clamping-bar 77 a spiral spring 79 is inserted, against which the lifting-bar bears in raising the clamping-bar 77, causing the strand to be clamped with a yielding pressure between the clamping-bar 77 and the fixed plate 76. When the projection 89 on its return movement has passed the latch 92, the lifting-bar 81 falls by its own, weight and i the horizontal arm 83, bearing against a nut of the hand wheel 54, thereby rocking the swinging frame 55 and compressing the spring 62. The release of the pawls 29 and 37 is accomplished by means of a vertically-sliding bar 96, held in ways at the side of the machine and provided with a curved plate 97, which extends beneath a stud 98 on the pawl 29, and with a pin 99, which projects beneath the pawl 37, so that the lifting of the bar 96 will disengage both pawls 29 and 37.

The bar 96 has attached thereto in a convenient'position to be engaged by the knee of the IIO operator an arm or bracket 100, enabling the bar to be raised and leave the hands free to draw back the fabric.

As the shed-former is pushed through the fabric it is liable to be slightly deflected from its direct diagonal course, and 1 form a tapering recess 101 beneath the clamping-plate 77, provided with converging sides 102 102, Which contact with the end of the shed-former and center it, so that the end of the strand-carrier will be brought in registration with anarroW slot 103.

WVhen the shed-former has reached the limit of its forward motion, the strand-carrier is advanced by the independent movement of the outer part a of the reciprocating block A movingthe end of the strand-carrier into the slot 103 and bringing its eye into registration With a hole 104. at the bottom of a tapering recess 105. The end of a cane-strand is then inserted through the eye of the strand-carrier, so that it will be drawn through the fabric in the return movement of the strand-carrier and shed-former, the operation of these parts being described in Letters Patent No. 639,601 aforesaid.

The clam ping-bar 77 is raised at the proper period in the return movement of the strandcarrier to hold' the cane-strand from move ment and cause it to be withdrawn from the eye of the strand-carrier, and I have found in practice that it is desirable to vary the time of clamping the strand relatively to the movement of the strand-carrier according to the quality and condition of the cane-strands, and 1 accomplish this by adjustably attaching the arm 88 to the lever 17 by means of slots 106 and bolts 107, enabling the clamping mechanism to be adjusted to clamp the strand at the desired point of time in the return movement of the strand-carrier.

As the shed-former is pushed forward and rotated by the fixed nut 7' it is desirable that the first juncture of the crossed strands of the fabric should lie in proper position to allow the tip of the shed-former to coil around them, and this is secured by means of the guideplate 72, which is shown in Fig. 1 and on a larger scale in Figs. 2 and 3, not only serves to withdraw the selvage-cord from one edge of the fabric, as shown in Fig. 2, but it separates the ends of the weft-strand by its pointed end 108, causing the ends of theweftstrands 109 to pass alternately over and under the guide-plate, while the edge 110 of the guide-plate serves to crowd the first cane strandlll of the warp toward the fabric and in position to be engaged by the tip of the retating spiral shed-former.

The cane fabric as it comes from the weaving-loom is shown in Fig. 2 and consists of a series of rectangular meshes, and in Fig. 1 1 a portion of the cane fabric is shown with diagonal strands 112 inserted in one direction.

The operation of my machine is as follows:

A cane fabric like that represented in Fig. 2 is wound upon theroll 39, which is held from turning too freely by the friction-belt 10. From the roll 39 the fabric is carried around rolls ll and 41 across the table 22 with the meshes of the fabric engaged by the teeth of the feed-wheels 25. From the table 22 the fabric passes around the roll 59 and rod 53 of the swinging take-up frame and is wound upon the take-up roll 12, having a. belt connection with a rotating pulley on the drivingshaft 3 by which a constant strain is exerted upon the fabric, but not sul'licient to move it across the table 22. A reciprocating motion is imparted to the shed-forum and strandcarrier, carrying them through the fabric by means of the cam 15, carrying the tip of the shed-former into the tapering recess 10l,eans ing the shed-carrier to be restored to its true alinement by the converging sides 102. The straml-earrier then advances to bring its eye beneath the hole 101, through which it receives a cane-strand, which is drawn into the fabric by the return movementof the strandcarrier. An illtOllIlit'tOlli; feeding motion is given to the fabric by the toothed feed-wheels 25, actuated by a pawl-aml-ratchet mechanism upon the withdrawal of the strand-carrier and shed-former. As the fabric is advanced it is drawn past the edge of the guide-plate 72, which restores the outer cane warp-straml in case it has been displaced, while the cords 70 '70 are withdrawn and taken up by the milled rolls 73 and '74:.

By exerting a constant strain upon the fabric by the belt 43 1 reduce the strain upon the fabric exerted by the teeth of the feed-wlwels. In other words, the pulling strain required to move the fabric along is divided between the strain exerted by the take up roll 12 and the teeth of the feed-wheels, thereby preventing the displacement of the fabric which would be liable to occur if the feeding motion were to be accomplished entirely by the feed-wheels or by the movement of the take-up roll.

By inclosing the shed-former in a sheath l itisheld from buckling when the resistance to the entrance and advance of the shml-former is unduly increased by its lack of proper registration with the meshes of the fabric or for any other cause.
