LOUIS JANSON, OF BROOKLYN, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 745,062, dated November 24, 1903-.
Application filed September 19, 1902. Serial No. 124,001. (No model.)
To ctZZ whom it may concern.-
Be it known that I, LOUIS JANSON, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Inserting Diagonal Strands in Woven- Oane Fabrics, of which the following is a full, clear, and exact description.
My invention relates to that class of machines adapted to insert diagonal strands in woven-cane fabrics; and the purpose of the invention is to so construct the machine that it will be simple, durable, and effective in operation and capable of being operated manually or by power, and, furthermore, to provide a machine in which a rotary depressing device is mounted to travel over the cane fabric, depressing the warp-strands at each side ofthe weftstrands, and to so reciprocate a needle adapted to carry the diagonal strands that the said needle will move concertedly with the depressing device, passing over the depressed Warp-strands and under the adjacent weft-strands.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of the machine. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal section through the bed of the machine, taken practically on the line 3 3 of Fig. 2, in which the parts are shown in normal position or in position to start. Fig. is substantially a similar view, but the needle is shown at the end of its receiving stroke, being in position to receive the diagonal strand. Fig. 5 is a transverse section through the bed of the machine, taken practically on the line 5 5 of Fig. 2, the rotary depressing device being shown up or in idle position. Fig. 6 is a section taken on the same line as the section in Fig. 5, but showing the rotary depressing device in lower and operative position. Fig. 7 is a plan view of the guide-bar for the needle and the rotary depressing device. Fig. 8 is a side view of the forward end portion of the guide-bar shown in Fig. 7. Fig. 9 is a longitudinal section through a poition of the guide-bar and a side elevation of the depressingwheel operating thereon, a section through the cane fabric and a side elevation of a portion of the needle, illustrating the position of the needle with respect to the depressing-wheel when the latter is operating on the fabric to form a passage for the needle while traveling to a position to receive a diagonal strand. Fig. 9 is a view similar to Fig. 9, but showing the position of the needle with reference to the depressing-wheel while the needle is carrying the diagonal strand through the cane fabric. Fig. 10 is a detail plan view of a portion of the needle-guide bar and cane fabric thereon, the eye portion of the needle in the position it occupies after having drawn a diagonal strand through the fabric, and a plan View of the gripping device for the delivered end of the diagonal strand to permit the separation of the needle from the strand. Fig. 11 is anenlarged transverse section through an extension from the bed, illustrating in detail the threading mechanism for the needle, the section being practically on the line ll 11 of Fig. 12, the guide portion of the threading mechanism showing in side elevation. Fig. 12 is a longitudinal section through the needie-threading mechanism, which section is taken practically on the line 12 12 of Fig. 11.
Fig. 13 is a section through the tracks between which the needle passes, a side elevation of the supporting or carrier block for the needle, and a transverse section through the needle, the section being taken practically on the line 13 13 of Fig. 3. Fig. l-it is a section taken practically on the line 14: 14 of Fig. 13. Fig. 15 is a side elevation of the cam forming a portion of the power-driving mechanism of the machine. Fig. 16 is alongitndinal central section through the bed of the machine,
illustrating a slight modification in the forma-' tion of the rotary depressing devices or mechanism. Fig. 17 is a perspective view of the wheel employed for depressing the cane fabric to receive the diagonal strands. Fig. 18 is a detail View illustrating the construction of the eye of the needle, and Fig. 19 is a detail view of mechanism actingin conjunction with the needle when it is about to be withdrawn from the diagonal strand it carries.
A represents a pillar or post upon which a base A is supported, and the said base preferably consists of upwardly and outwardly flaring side andend sections, as is shown in Figs. 1 and 2, and outwardly-extending horizontal upper marginal flanges 10. At one end of the base on the end flange the trunnions of a roller 11 are journaled in suitable bearings 12, and from the same flange downwardly and outwardly extending hangers 13 are carried, in which hangers a drum 14 is removably mounted, adapted to carry the woven cane A through which the diagonal strand is to be passed. Preferably at the lower end of each hanger 13 a horizontal slot 15 is formed to receive the trunnions of the drum 14, and pins 16 normally close the said slots, as is shown in Fig. l. On one trunnion of the said drum 14 a crank-handle 17 is secured to facilitate the operation of the drum. At the opposite end of the base and upon the end flange 10 a second roller 18 is journaled in suitable bearings 19, and from this latter end of the base hangers 20 are projected downward, having slots 21 produced therein to receive the trunnions of a drum 23, the slots 21 being normally closed by pins 22 or their equivalents. The woven cane A is passed from the drum 14 to the drum 23, or vice versa, and a trunnion of the drum 23 is provided with a suitable crank-hanger 24, as is shown in Fig. 2.
A drive shaft 25 is passed diagonally through the pillar or post A, as is indicated by dotted lines in Fig. 2, and at one end of this shaft 25 a driving-pulley 26 is located, while at the opposite end of the shaft a bevelgear 27 is secured, adapted to mesh with a similar gear 28 on a short horizontal shaft- 29, journaled in suitable bearings extended from the said post A, as is shown in Fig. 1. An arm 30 is pivotally mounted on the shaft 29, and the said arm 30 is provided with a roller 33, which roller travels in a race 32, formed in one side of aheart-shaped cam 31, (illustrated particularly in Fig. 15,) which cam is secured upon one end of the shaft 29, as is shown in Figs. 1 and 2. The arm 30 is pivotally attached to a lever-arm 34, the said lever-arm being suitably pivoted in bearings on the support for the machine or on a projection from the lower portion of the supporting post or pillar A of the machine.
The bed or operative section of the machine extends diagonallyof the base A, as is shown particularly in Fig. 2, and the said bed in its entirety is designated by the reference-letter O. This bed 0 is supported by brackets D and D, located on the side flanges 10 of the base A near diagonally opposite ends of the'base, and these brackets D and D will be hereinafter fully described. From the bracket D track-bars E are projected horizontally in parallel lines, a cross-section of which track-bars is fully shown in Fig. 13. These track-bars are connected at their inner ends by, preferably, an angular cross-bar e, which is secured to the bracket D and to the base A. Each track E is provided with a T-head 36, as is best shown in Fig. 13, whereby longitudinal upper ribs are formed on each track. On the said inner ribs formed by the T- heads 36 carrier or supporting blocks are mounted to slide, the said carrierblocks consisting, preferably, of a substantially U-shaped body 37, having side members or plates 40, as is shown best in Fig. 14, and these side plates carry upper rollers 38 and lower rollers 39. The upper rollers 38 engage with the upper surfaces of the inner ribs of the tracks E and the lower rollers 39 with the nndersurfaces of the said ribs. Preferably each carrier or supporting block 37 is provided with a sleeve 41, fixed to its body portion and extending longitudinally of the bed (J of the machine, as is particularly shown in Fig. 14. Within each sleeve 41 a tubular section 42, of rubber, leather, or other elastic material, is located, and through the said tubular sections 42 the shank of the needle 43 of the machine is passed, which needle is adapted to draw the diagonal strand through the woven cane.
The carrier or supportingblocks 37 are adapted to support the needle between its ends when the needle is in its normal position, as is shown in Fig. 3; but when the needle is in position to receive adiagonal strand, as is shown in Fig. 4, the carrier or supporting blocks 37 are brought close together in any suitable or approved manner, spreading out again in any suitable w'ay-as, for example, through the medium of pins of different lengths extending from the inner faces of the tracks E, so as to permit sundry of the blocks to pass, while others will be held stationary in position to support the needle when it is carried outward or travels in a direction to draw a diagonal strand through the fabric. The blocks are brought to their assembled position (shown in Fig. 4) through the medium of acarriagelF, which is preferably rectangular, as is shown in Fig. 2, and is adapted to travel and be guided upon the upper portions of the tracks E.
It may here be remarked that set-screws 42 are employed in connection with the supporting or carrier blocks 37 to cause the flexible or yielding inner sleeves 42 to have sufficient hearing at all times on the needle 43 to enable the needle in its forward or rearward movement to bring about a similar movement on the part of the said bearing-blocks.
' The carriage F is provided with an opening 44 therein, the length of which opening regulates the distance the needle shall move at its point to and from the rotary depressing devices, to be hereinafter described, as the point of the needle assumes one position relative to such devices when the needle is being carried to a position to receive a diagonal strand, as
IIO
48 from the upper movable section 47 of each bracket D and D horizontal bars 69 are carried fromone bracket to the other in parallel lines, and each side bar 69 for each upper section 47 of a bracket is provided with a longitudinal guide-slot 70, and said slots at what may be termed the rear end portions of the side plates 69 are upwardly curved, as is illustrated at 71 in Figs. 3 and 4, for the purpose of carrying a depressing-wheel H, to be hereinafter described, in an upward direction when the sections of the brackets D and D are brought together, so that the said wheel H will not be in the way when the needle is to be threaded with a strand to be carried diagonally through the fabric.
At the lower portion of each side plate 69 angular additional side plates 72 are secured, as is shown in Figs. 5 and 6, and in the bottom portions of these additional side plates 72 recesses 73 are made, which receive the projections 62 on the needle-guide bar G when the sections of the brackets D and D" are brought together for the purpose of passing a diagonal strand through the fabric held between them.
The depressing-wheel H, above referred to, is provided with trunnions 74, which travel in the slots 70, and these trunnions 74 are journaled in the end portions of links 75, carried in parallelism to a pivotal engagement with a post 76, which extends upward from the inner end of the carriage F, as is shown in Figs. 3 and 4, so that the depressing-wheel H is given movement through the movement of the carriage F, and the carriage is not given movement until the cross-head 44 engages with one or the other of its end walls. The depressing-wheel H is provided with projections 77, arranged in transverse pairs, so as to form a central circumferential channel between the said projections, and the position of the wheel H is such that the channel thus formed is immediately over the longitudinal channel 64 in the guide-bar G for the needle, so that the needle will not be interrupted in its passage through the fabric on account of the action of the wheel on the fabric, which wheel H through the medium of its lug 77 as itis moved over the fabric depresses the warp-strands X of the fabric, permitting the needle, which closely follows said wheel and whose eye is immediately below the vertical center of the wheel, as is illustrated in Fig. 9, to pass over the depressed strands X and under the adja cent weft-strands X, and in this manner as the wheel H moves in one direction the needle quickly follows it, and the needle is practically diagonally woven in the fabric and will at its return movement draw the strand diagonally through the fabric as the needle recedes therefrom. The position of the needie and diagonal strand with reference to the warp and weft strands is clearly shown in Fig. 10.
Preferably in the construction of the depressing-wheel H recesses 78 are produced in the side edges between the projections 77, so that the said wheel will not interfere with the projections 62 upon the needleguide bar G. Diagonal guideways or depressions 78 are formed between the projections 77, as is illustrated in Fig. 17, so that the depressing-wheel may better adapt itself to the strands of the cane fabric over which it is to pass; but such guideways or depressions are not absolutely necessary and may be dispensed with, if desired.
Direct motion is imparted to the wheel H through the medium of a rack-bar 79, secured to the inner face of one of the side bars 69, and a gear 80 is located at one side of the supporting-arm for the wheel H adjacent to the said rack, the said gear being mounted upon a suitable stud 81. At the opposite side of the said arm 75 a pinion 82 is carried by the said stud. The gear 80 engages with the rack 79, while the pinion 82 engages with a gear 83, which is fast upon one side of the wheel H, as is best shown in Figs. 5 and 6. In this manner it will be observed that through the rack and gear 79 and 80 rotary motion is communicated to the wheel H by the pinion 82, operated from the gear 80 and the gear 83 on the said wheel.
The upper and lower portions of the bed C of the machine are moved to and from each other by a foot-treadle 84 at one side of the supporting-pillar A, which treadle is secured upon a shaft 84, mounted to turn in the said pillar-support, and at the opposite side of the pillar-support a crank-arm 85 is secured.
At the inner end of the foot-treadle 84 one end of a connecting-rod 86 is pivoted, the other end being pivotally attached to a lever 87, fulcrumed upon a post 88, extending down from the flange 10 of the base, and the lever 87 is also connected with one of the shafts 49 on the upper section of the bed, while upon the opposite side of the pillar A the connecting-rod 86 is duplicated and the lever 87, the latter being attached to the opposite shaft 49, while the connecting-rod is con nected with the crank-arm 85, and a spring 89 is attached to the crank-arm 85 and to the base A, acting to normally hold the two sections of the bed separated.
The threading mechanism for the needle 43 is as follows: At the outer side of the lower fixed section 46 of the bracket D an angular table 90 is secured,- consisting of a horizontal and a vertical member, as is particularly shown in Fig. 3, 4, 11, and 12, having a slot 91 produced continuously in both of its members. A buffer-block 93 is secured upon the upper face of the horizontal member of the table 90, as is particularly shown in Fig. 12, and this buffer-block at its inner end is provided with a recess 92, which receives the point of the needle 43 when the needle is carried to the end of its rearward stroke to receive a strand to be carried diagonally through the fabric on the machine. At the bottom portion of the horizontal member of is shown in Fig. 9, and another position when the needle has received a strand and is carrying it through the fabric, as is shown in Fig. 9
In the opening 44 of the carriage F a crosshead 44 is adapted to slide in suitable bearings, as is shown in Figs. 2 and 3, and in this cross-head the outer end of the needle 43 is secured in any suitable or approved manner, the head 43 of the needle being at its inner end. Motion is imparted to the carriage F when the cross-head 44 has engaged with the inner end of the carriage by means of a link connection 45 with a post 45, extending downward from the cross head, the said link 45 being pivotally attached to the lever-arm 34, as is particularly shown in Fig. 1, so that the driving mechanism heretofore described opcrates directly upon the cross head and through the cross-head upon the carriage F; but it will be understood that the cross-head 44 may be so formed that it may be manually operated, if so desired.
The brackets D and D heretofore referred to are alike in construction, and each consists of a lower section 46 and an upper section 47. The lower sections 46 of the brackets D and D are securely and diagonally attached to the side flanges 10 by bolts or their equivalents, while the upper sections 47 are movable to and from the lower sections 46. Each upper section of a bracket is provided withaninverted-U-shapedsection48. (Shown best in Figs. 5 and 6.)
The body portion of the upper section 47 of each bracket D and D is secured to a pin or vertical shaft 49, the said shafts being at opposite sides of the bed 0, as is shown in Fig.
- 2. The upper sections 47 of the brackets D in Figs. 5 and 6.
and D are usually attached to their shafts 49 by means of upper and lower nuts 50 and 51, secured to the said shafts, as is also shown At the upper end of each shaft 49 an arm 52 is secured to the upper surface of the upper or movable section 47 of each bracket, preferably by means of the upper nuts 50 on the shaft 49, and these arms 52, as is shown in Figs. 2 and 5 and in Fig. 6, extend in the direction of the bed O, and at their lower ends carry horizontal extensions 53, and said extensions 53 support horizontal plates 54,vertically located in parallelism at suitable distances apart, as is especially shown in Figs.5 and 6,0ne vertical guideplate 54 being supported by each vertical arm 52.
Preferably the opposing guide-plates 54 are connected at their end portions by lower crossbars 55, and from these cross-bars 55 arms 56 extend to one side of the bed. Each arm 56 is of angular construction, being provided with an upwardlyextending member 56*. These arms 56 are adjacent to posts 57,which extend upward from the flanges 10 of the base A and carry pointed projections 58 at their upper ends, adapted to enter apertures 60 in horizontal extensions 59 from the U-shaped Incidentally the projections 58 likewise serve to hold in position the cane fabric between the two sections of the bracket, and when the upper sections 47 of the brackets D and Dare carried upward the vertical extensions 56 from the angular arms 56 will likewise be carried upward and will serve to disengage the fabric from the projections 48. The plates 54 will perform the same function as the sections 47 of the brackets are carried upward, serving at this time to disengage the fabric from the projection from a guide-bar G, to be hereinafter described, and through which the needle is passed which carriesthe diagonal strand.
It may here be remarked that preferably each shaft 49 is provided with a shoulder 50, (shown in Fig. 6,) which limits the upward movement of said shafts.
In the upper edge of each lower fixed section 46 of each bracket D and D an opening 61 is produced, narrower at its bottom than at its top. Vertical bars 68 are supported by the bottom walls of the openings 61 in the fixed bracket-sections 46, the bars 68 extending from one bracket-section 46 to the other, and these vertical bars 68 act as supports for the guide-bar G, heretofore referred to.
The guide-bar G is shown in detail in Fig. 7 and is provided with projections 62 from its upper face, the projections being preferably arranged in parallel lines near each longitudinal edge of the bar, and between the rows of projections 62 diagonal recesses 63 are produced in the upper face of the bar G, preferably the same distance apart one from the other, and a central longitudinal recess 64 crosses all of the diagonal recesses 63 and extends from one end of the guide-bar G to the other. The projections 62 from the guide-bar G are adapted to enter the spaces formed in the weaving of cane in the usual open manner, and the diagonal recesses 63 are adapted to receive projections from adepressing-wheel acting on the fabric held between the sections of the brackets D and D to depress the Warpstrands, so that the needle in passing through the central channel or recess 64 will pass'over the depressed warp-strands and under the adjacent weft-strands.
At the outer end of the needle-guide bar G a recess 65 is made in one side, and'at the junction of the walls of the recess 65 a curved or rounded surface 66 is formed over which the eye of the needle passes when the needle is carried toward the bar G, and the said surface 66 serves to guide the needle to the recess or channel 64. At one side of the recess 65 a vertical anvil-block 67 is formed for a purpose to be hereinafter particularly described.
At each inner side wall of each projection IIC the said table one end of a spring 94 is secured, and the opposite end 95 of the said spring is curved upward and is made to bear upon the under side of the shank of the needle 43, as is shown also in Fig. 12, for the purpose of supporting said shank of the needle, and the upper end 95 of this spring is immediately below a guide member 96, beneath which the needle passes. This guide member is located a suitable distance below the upper surface of the horizontal member of the table 90, as is also shown in Fig. 12, and at its outer portion is given a decidedly upward curve. The said upwardly-curved outer portion of the upper guide 96 extends over the recessed end'of the buffer 93. This guide 96 is secured to a block 97, which in its turn is attached to the horizontal member of the table 90, and adjacent to the curved surface of the guide extension 96 from the said block 97 a pawl 98 is pivoted, which pawl adjacent to the guide 96 is downwardly inclined. The inclination of the pawl 98 is such that it is directed to the point of the needle when the said point of the needle is in position of rest at the end of its rearward stroke, as is shown in Fig. 11. -The pawl 98 is held in its normal position relative to the guide member 96 by means of a spring 99, (shown best in Fig. 2,) which spring is suitably applied, and in the surface of the pawl 98 which is opposed to the guide extension 96 from the block 97 a channel 100 is made. This channel receives the strand 101, which is to be delivered to the needle 43 and is to be a diagonal strand in the fabric, and directs the said strand through the eye of the needle. After passing through the eye of the needle the strand is prevented from passing too far downward by engagement with a stirrup 102, secured to the under face of the horizontal member of the table 90, as is shown in Fig. 11, so that when the needle is drawn backward to carry the strand diagonally through the fabric the strand 101 to be thus carried is bent over at the point of the needle, as is shown in Fig. 10, and said strand is gently drawn through the space between the guide 96 and the pawl 98 as the needle makes its return movement. Under this construction it is evident that the needle may be quickly threaded, and the operator is assured that the strand for threading the needle is properly passed through the eye of the same.
It may be here remarked that the forward wall of the eye of the needle is made more or less sha p fora purpose to be hereinafter described, and this sharpness of the forward wall of the eye of the needle does not act detrimentally on the strand passed through the eye of said needle as the strand is being drawn through the fabric, as at such time little or no resistance is offered to the passage of the strand. After the needle has carried the strand through the fabric the needle is released from the fabric, preferably in the following manner and as is best illustrated in taohed.
Figs. 2, 3, and 10: A spring-controlled bolt 103 is mounted to slide in suitable bearings 104, located upon the upper portion of the lower convexed section 46 of the bracket D, and the head of said spring-controlled bolt 103 is directly opposite the anvil 66 of the guide-bar G for the needle. A member of an elbow-lever 105 engages with the outer end of the bolt 103, the said lever being pivoted upon a suitable support upon the aforesaid bracket D, and to the other member of the said elbow-lever 105a rod 106 is pivotally at- This rod, as is particularly shown in Fig. 2, extends in direction of the outer end of the track-section of the bed outsideof one of the said tracks E, and at the outer end of the said rod 106 a link 107 is pivotally attached, said link being likewise pivotally attached to the inner surface of the track E, adjacent to the outer face of which the rod 106 passes. This link 107 is provided at its outer edge with a pivoted dog 108, the upper end of which dog extends upward, so as to be in the path of the carriage F, as is shown in dotted lines in Fig. 3, and the said carriage at that side where the dog 108 is located is provided with a downwardly-extending spur or lug 109, as is also best shown in Fig. 3. When the needle has drawn the strand 101 through the fabric, as is shown in Fig. 10, the carriage F will have reached such an outer position as to engage with the upwardlyprojecting portion of the dog 10S, pressing the lower portion of the dog against the link 107 and compelling the upper portion of the link to move outward, and consequently draw the rod 106 in the same direction, which action on the part of the rod 106 causes the elbow-lever 105 to press the spring-controlled bolt 103 inward in direction of the anvil 66 to clamp the delivered end of the strand 101 between the bolt and the anvil. The carriage F has still further outward movement, and in effecting this further outward movement the needle is drawn outward, and the sharp wall ofits eye, heretofore mentioned, will cause the delivered end of the strand to be severed, as the strand is firmly held at such time in the manner stated. As the carriage F completes its rearward movement the lug 109 slips over the dog 10S, permitting the rod 106 to move inward and causing the elbow-lever 105 to release its pressure on the bolt 103, which bolt, owing to its spring action, will return to its normalposition. WhenthecarriageFmakes its inward movement to bring the needle in position to receive a strand, the lug 109 sim ply passes by the dog 108, as the lower por- ICC tion of the dog will leave the link 107, and
consequently the carriage F will at such time have no controlling action on the clampingbolt 103.
In Fig. 16 I have shown a slight modification in the construction of the improved structure or bed of the machine in which the needle-guide plate G is substituted bya pressurewheel H and connected mechanism corre- -carriage F, the eye of the needle will have sponding in construction and operation to the wheel H, heretofore described. The wheel H travels at all times below the wheel H, the projections or lugs from one wheel entering the spaces between the projections or lugs of the opposing wheel, and consequently side pieces 69 are employed in the lower fixed portion of the upper structure of the bed, ex-
tending to the upper side pieces 69, and the said side pieces 69 are provided with slots 70, in which the trunnion of the wheel H travels. slots 70 incline downward, or in a contrary direction to the inclination of the terminals 71 of the upper slots, and in connection with the lower section of the bed just described a rack 79* is employed, adapted to be engaged by a gear 80, operating a pinion corresponding to the pinion 81 described, which pinion acts upon a gear on the depressing-wheel H corresponding to the gear 83, also previously described. A second stud or post 76 is extended downward from the carriage F, to which stud arms or links 75 are pivoted,
which arms or links 75 carry the depressing wheel H and associate gearing.
In operation, supposing the needle 43 to be in the initial position shown in Fig. 3 and the upper section of the bed or upper structure being raised or in normal position, the openly-woven cane fabric K, with warp and weft strands woven upon any suitable machine, is passed diagonally over the base between the sections of the bed or upper structure O, the said fabric being wound upon one reelsupported upon the base andisadapted for attach'mentto the opposing reel as the diagonal strands are passed through the fabric. In placing the cane fabric adapted to receive the diagonal'strands the projections 62 on the needle-guide G and the projections 58 from the standards 57, attached to the bracketsD and D, are made to enter the openings in the fabric K, and then the treadle 84 is pressed down, closing the upper section of the upper structure or bed-section 0 upon the lower section. Power is now applied to the cross-head 44 of the carriage F and the needle 43 is started upon its forward movement,the guides 37 closing up as the needle advances, as is shown in Fig. 4. When the cross-head carrying the needle reaches the inner end of the reached a position below the depressing-wheel H practically in vertical alinement with the center of the wheel, as is shown in Fig. 9, and the carriage F will then be forced forward by the said cross-head 44, causing the wheel H to revolve upon the needle-guide G and the needle to travel in the channel 64 of said guide Gin the above-mentioned position relative to the depressing-wheel H. The projecti'ons 77 on the wheel H asthe said wheel advances over the fabric depress the warpstrands at each side of the Weft-strands, and the needle, moving concertedly with the depressing device, will be interlaced through The outer terminals 71 of the said,
the fabric, passing over the depressed warpstrands and under the adjacent weft-strands diagonally of the fabric. The needle 43 remains in the fabric after its eye has passed beyond the outer margin of the fabric onthe forward movement of the needle, and the eye of the needle at the end of its forward throw will have entered a recess 92 in the barrier 93, and the trunnion of the wheel H will at that time have entered the upwardlyinclined terminals 71 of the slots 70, carrying the said wheel H to an upper position and permitting the threading of the needle to conveniently take place. At this time astrand 101 is threaded between the parts 96 and 98 of the threading mechanism in the manner heretofore described, and after the needle is threaded it is carried back bythe reverse movement of the actuating mechanism described connected with the cross-head 44 in the carriage F. As the cross-head 44 has limited sliding movement in the carriage F, before the cross-head acts to propel the carriage at the initial return movement of the crosshead, the eye of the needle, with the strand 101 connected, will be drawn to a point in advance of thedepressing-wheel H, as is shown in Fig. 9 before the said wheel H starts upon its return journey, as such return cannot take place until the cross-head 44 is in engagement with the outer end portion of the carriage. Under this independent movement of the cross-head 44 the eye of the needle is taken out of possible contact with the depressingwheel H, and the strand 101, carried by the needle, cannot be chafed at the needle-eye while being drawn through the fabric. The independent movement of the cross-head 44 relative to the carriage F at the forward movement of the former brings the eye of the needle, as stated, centrally beneath the depressing-wheel H in order that the eye or point of the needle without failure will enter the path in the fabric formed by the wheel H in depressing the warp-strands at each side of the weft-strands. On the return movement of the needle the attached diagonal strand 101 is drawn through the above-mentioned path, and after the strand 101 has been drawn through and has passed the opposite edge of the fabric, as is shown in Fig. 10, the clamping devices for the strands therein particularly illustrated act in the manner heretofore described to hold the strand, so that the needle as it approaches the finish of its return stroke is automatically disconnected from the strand, and at the finale of the return stroke of the needle the clamping devices automatically pass out of the path of the needle, leaving said path free for the needle in its next forward movement.
