MACHINE FOR W'IEAVING REED FABRIC.

Application filed. December 29, 1924:. Serial No. 758,548.

' or ornamentation thereof, relative to the single course of over and under weaving f the filler strand upon the stakes and which comprises the main body of the finished fab- Another object of the invention is to so construct the machine that the weaving of the designs in a fabric is automatically controlled by a tape of peculiar construction which actuates the stake staggering means to hold the desired stakes in a manner permitting the laying of the strand with respect thereto, thus pro'dncin g the design or ornamentation therein, the designs, of course, varying in accord.- ance with the particular tape or ribbon to be used. p

A further object of the invention is to produce a machine wherein the designs or ornamentations are uniform and may be produced upon opposite sides of the finished fabric so that when the same is applied to an article, as for instance a baby carriage, a design appears in symmetrical arrangement and proportions upon each side of the baby carriage.

My invention further consists in the form, construction, and arrangement. and co-operation of the various parts thereof, whereby the above mentioned objects, together with other objects and advantages which will hereinafter appear. are readily attainable and my inven tion will be more readily understood by reference to the accompanying drawings which illustrate that form of my invention which I consider at this time the preferred form.

The improved machine as herein illus trated and described is similar in some re spects to the machine forming the subjectmatter of my prior Patent No; 1,459,781 issued on June 26, 1923. The embodiment of the present invention shown herein comprises generally the followlng parts:

Frame.

Stake holding and positioning means.

Stake manipulating and controlling means.

Filler strand inserting means.

Filler strand packing mechanism, and.

Driving mechanism. 7

In order to facilitate and simplify the description of the various parts and the operation of the machine I will describe said parts generally in the order above outlined.

The frame. The frame comprises a base portion 1, a

filler strand packing mechanism guide portion 2, and fabric limiting portion 3. The base portion includes a bottom base flange 4, an upstanding annular flange 5 and a horizontal top wall 6, there being a centrally disposed tubular sleeve 6 depending from said top wall and connecting it with a second horizontal wall 6" near the flange 4. The filler strand packing mechanism guide portion 2 is made up of two horizontally, disposed circular plates 7 and 8, respectively, which are rigidly connected together in vertically spaced apart relation by means of a set or plurality of upright rods 99. The top plate 8 is of a diameter greater than that of the bottom plate 7 and depending from the mar ginal part of said top plate is a second set or plurality of upright rods 10-10, to the bottom ends of which is fixed a ring 11 in the plane of the plate 7. The

rods

9 and 1 0 are positioned on radial lines and are secured at their top and bottom ends to said plates and ring, as for example by the nuts 12 and 13 which permits of a more ready assembly of the parts. The

rods

9 and 10 form guides for the sliding parts of the filler strand packing means. In Fig. 2 only the two diametrically opposite sets ofrods 9 and 10 are shown, the other sets of rods which would be seen in this view being purposely omitted for the sake of clearness and simplicity.

The fabric limiting portion of the frame is composed of a ring 14: mounted on the top plate 8, just inside the annular ow of rods 9 and is properly positioned thereon in a manner permitting its ready removal and replacement by dowel pins 15. Secured in said ring 14- and upstanding therefrom is a plurality of members 16 as best shown in Figs. 1, 2 and 5. In Fig. 2 only the two oppositely disposed members are shown, the others being omitted for sake of clearness. There is one of said members 16 for every stake in the reed fabric and the purpose thereof will more fully appear later. The members 16 are given the shape desired in the finished fabric and act to limit the inward forming tendency of the fabric. The top end portions of said members are fixed in position in the peripheral marginal part of a plate 17, which construction rigidly holds all of said members 16 in proper spaced relation.

Stake holding and positioning means.

The stake holding and positioning means comprises in part a ring or annular eclgewise disposed band 20 in which are provided a plurality of spaced holes to receive the bottom ends of the stakes 21 which fit snugly therein. As said band is of the kind employed in the machine of my prior patent before mentioned it is not thought necessary to more fully illustrate or describe the same in detail herein. The said ring or annular band with the stakes 21 positioned thereon may be placed upon the member 14 where it will snugly surround or embrace the bottom ends of the fabric limiting members 16. hen thus positioned, the stakes 21 upstand from said band and will follow closely the general formation of the members 16. Having thus generally described the stake positioning and holding means together with the fabric limiting means I will next describe the means by which the said stakes are manipulated to form the shed in which the filler strand is laid in single courses and in groups of courses upon desired stakes and the means by which said manipulation means is automatically actuated and controlled.

Sta/re manipulating and controlling means.

The stake manipulating and controlling means includes a circular plate 22 of a size substantially coextensive with the outer portions of the top ends of the members 16, and in one sense forming a continuation thereof. Said plate is removably mounted and positioned upon the plate 17 before mentioned as by means of the dowel pins 23 (see Fig. 2) so that when they are operatively engaged they will rotate together. In the periphery of said plate 22 is provided a concave groove 24 in which a portion of a helical coiled spring 25 is seated. Said spring is of such a size relative to said plate 22 that it tends to compress itself upon the plate and into said groove 24., said spring being formed with. two complete convolutions for ever stake 21 of the fabric. This spring is so poiitioned with respect to the stakes that each stake can be moved into contiguous V-shaped spaces formed by oppositely disposed portions of the spring as is best shown in Fi 9. The stakes may move into the associated Vshaped space a certain distance but cannot move out of the spring entirely and said spring acts to carry the stakes in proper spaced relation during that interral in, which they are separated or removed from the plate 22 for the insertion of the filler strand. The plate 22 is provided in its periphery with a plurality of arcuately spaced, vertical recesses or pockets 26 for the accommodation of the llfi prevented from leaving their asso iated recesses. In order to provide a sr-rteguard to prevent said stakes from springing out ol' their respective recesses 26 for any reason whatsoever, I provide a second but smaller coiled spring which encircles the stakes ill just below the helical stake guiding spring Upon the top of the plate 22 is fixed a duplei; gear ring comprising top and bottom

external gear members

27 and 28, respectively. Preferably the bottom gear member 28 is positioned between the top gear member and plate 22 and lag screws 2:) pass through the top gear member and are threaded into said plate. The gear ring 28 while held in position by the gear ring 2? may be driven a direction opposite that it the gear 2? when necessary, as will later appear. l ithin said duplex gear ring is a non-rotative circular plate 30, said plate. and member having coacting flange and groove construction by means of which said plate ass s the menbers 16 in supporting the plate 5-3 The pila e is keyed to the top end of a centrally dirposed, shalt 30 which extends down through the

plates

22, 17, 8 and 7, respectively, to have its bottom end non-rotati-vely secured in the sleeve 6" before mentioned, the plates 7 and 8 having suitable bearing sleeves 7 and 8, respectively, journalled upon said shaft. An chored at their bottom ends in said plate 30 are two dian'ietrically opposite upright posts or standards 3l-3l and disposed in planes at a right angle to the plane of said posts are laterally extending blocks 32, one of which is shown in perspective in Fi l, Each block is secured in position upon the plate 30 by means of bolts which exten d throu the tapered sides as shown in The outer end of each block 32 has extend ng side portions 35 which are thicker than the inner ends of said plate and the bottom surface of said thickened end and side parts are rounded upwardly in opposite directions from the middle thereof, as best shown in if'aig. 8. To said bottom surface is secured coacting wear plates EMS-37 which are spaced apart at the middle of the block in line with. a groove 38 in the bottom portion of the block at the middle thereof. Each bottou'i wear plate 3? has a shallow groove 37 see ll '4') in its top surface, and said bottom wear plates, together with the top wear plates define a shallow channel 39 which intercepts the groove in said block in the plane ol the ring 28. In said groove 38 is provided a flat, radially extending bar 38* which is ustably secured at its inner end to the plate 30 by means of bolts 38 passing through short longitudinal slots 38 in said bar and threading into said plate, enlarged openings 3-iin the block 32 providing access to said bolts for the purpose oi tightening or loosening them. The purpose of this channel 39 is to receive and'guide a flexible metallic ribbon or tape 40 which is provided along one margin with teeth ll, meshing with the ring 28 and along its other margin with a plurality of humps and intermediate depressions -12 and 43, which operate to control the action of the stake manipulating means in a manner hereinafter to appear.

In the top surface of each block is provided a groove 44: which ext nds radially with respect to the centrally disposed non-rotative shaft 30. Said groove is adapted to receive rib 425011 the underside of the base 4:6 of an upright standard 4-7. A bolt 46 extends through a slot 46 in said standard base 46 (see Fig. l) and is threaded into the block 32 in a manner permitting a radially inward or outward adjustment of said standard upon said block To the outer end of the bar 38 associated with each block is fixed a depending guide member 48 in said guide member is formed a rectana 11' slot 49 extending parallel with and in the median plane of said recess. To one side oi raid slot, said guide member has utwzirdly extending top and bottom cars 50.

Pivoted between said ears by means of a pin 51, is one end of a lever 52- vhich extends toward and terminates at its other end in sub stantially the vertical plane of the groove 44 in the block A coiled spring 52 surrounds said pivoted end oi? the lever and is attached one end to one of the ears 50 and at its other end to said lever in such a manner as to iuu'mally urge the free end of said lever inwardly toward the associated block To the free end of fit-id lever is pivotet a trigger or latch 53 which, under the out ward. swinging movement of the lever, is adaptcdto engage the projectin top end of the desired stalces 21. Said trigger is pivoted to said free end of the lever 52 so as to be capable of a lii iitcd swinging movement, a spring 53 being interposed between said lever and trigger for yieldingly holding it in a n'edctermined position with respect to said ever. In the slot 49 ot' the guide member 4-8 's slidably mo unteda pusher bar 54 0t reeangular cross section which is arranged in the plane of thetape or ribbon l0 where it passes through the recess 38 in the block The inner end of said pusher bar is bifurated to embrace opposite sides of the notch and recessed mar fln of said ribbon or tape, and carried by said end of said pusher bar a roller adapted to ride the various humps and depressions 42 and 423, respectively and thus impart a corresponding in and out reciprocation to said pusher bar. The outer end of said p sher bar engages against a Lupe ll l Inn

roller 52* carried by the lever 52, as best shown in Fig. 9, the spring 52' acting to hold said lever in engagement with said pusher bar. it is apparent that as the gear ring 28 is rotated, the ribbon or tape will move through the channel 39 at the same rate of movement and that as each time a hump or projection of the tape or ribbon engages the roller of the pusher bar a reciprocation is imparted thereto which, through the lever 52, causes the latch or trigger to engage the desired sta e and flex or stagger it outwardly. Thus by positioning the humps or projections on the tape in the desired manner any one stake or any one group of stakes may be staggered to provide the shed for the pasof the filler strand weaving means. To prevent the lever 52 from swinging outwardly too far, under the action of the pusher rod, 1 provide on the top of said lever a pin 52 which is adapted to engage a stop shoulder 56 secured to the block 32 and overhanging said lover.

The controlling ribbons or tapes are wound upon. and unwound from reels which are adapted to be positively driven so that, although said ribbons or tapes mesh. with the lower gear of the duplex gear ring before mentioned they do not rely upon this engagement alone for their movement. To this end I provide the following construction Fined to the two upright posts 3l31 before mentioned are brackets 60-60, each of which includes a horizontally arranged yoke 61-61. Said yolres face in opposite directions and are disposed in a plane extending at a rightangle to that of the blocks and supported thereupon is a rectangular open frame-lil e plate 63 which connects said yoires together. The outer ends of said yolres terminate in horizontally spaced bearing sleeves 65-65 in which are

journalled shafts

66 and 6?, the ends of which project a suitable distance beyond said bearing sleeves 65. Loosely mounted on the ends of the shaft 66 are

reels

68 and 68 and loosely mounted on the ends of the shaft 6'? are

similar reels

69 and 69*. respectively. The ends of said shafts beyond the

reels

68, 69 are each provided with a pulley 1 0 and 71, respectively, over which a belt not shown) is trained to operaaively connect them together. On the inner face of each reel is secured a clutch member '1' 2!' 3*74; and 75, rea ectively. Keyed to the shafts 66-67 between the yoke sleeves 65 and the clutch members before mentioned are associated clutch collars 72'l 37 l and. 75, respectively. The clutch members ?2-73 are connected together by a U- shaped member 76 and the clutch members l f -75 are also connected together by a similar ll-shaped member '77. The adjacent end n'iembers 78 of said ll-shaped members are slotted as at 79 and through said slots extend screws 80 which are threaded into the pen frame plate 63 near its middle. The ends of said U-shaped members connected to said associated clutch collars are further connected by arched brace bars 76'77, respectively. Journalled at its top end in said plate 63 between the members 78 is a manually operable shaft 81, the bottom end of which is journalled in abracket 82 clamped to one of the posts 31. To said shaft, which is axially aligned with the shaft 80 and preferably below the bracket 82 fined a handle 83 by means of which said shaft 81 may be turned. To the top end of said shaft 81 above the plate (33 is fixed a lever 84 with oppositely disposer slotted arms which overhang and are operatively connected to the members 78 of said lJ-shaped members, as best shown in Fig. 1]..

Fined to the shaft 67 between the bearings 65-65 is a pulley 85 which is driven ly a belt 86 from a smaller pulley 8'7 secured to a short iorizontal shaft 88 journalled in bearing sleeves 88 upstandino from a rectangular bracket plate 89 bolted to the plate 30 before mentioned. This plate 80 includes an upright bearino' sleeve 00 which overhangs the gear rings Fir--28 and in which is journalled a short vertical shaft 91 to the top end of which fixed a bevel pinion 92. Said pinion 1. eshes with a bevel gear 93 on the horizontal shaft 88. To the bottom end of said upright shaft 01 is lined a gear pinion 94 which meshes with the top gear ring 27. Thus said gear ring rotates it will, through the gearing and belt above mentioned drive the shaft- 67 which, in turn, drives t 1e shaft )6. With the clutclrcollars 73 and 74" engaged with their associated clutch members on the

reels

68 and 69, said reels will act to wind up the tapes 40-40 which pass through the associated guide channels 3. -30 of the blocks 32 after unwinding from the reels (58 and 69?, respectively. Said. tapes are of such length that when the fabric is completed, the ends of said tapes on the unwinding or paying off reels are approached. However, it is not necessary in starting a. new fabric to rewind the tape upon the depleted reel but all that is necessary is to actuate the handle 83 to shift the clutc members 72 and 75 into engagement with the c utch members 7275 on the respective reels (58 and 69 when said reels become the winding reels and the other reels become the unwinding or pay otl' reels. This shifting of the clutches is performed once at the completion of each woven fabric. As the tape is wound and unwound from the associated reels 68-60 and Gib-439 from the same side thereof as best shown in Fig. 1, it is advisable to provide a 1 ride for the ta e, being unwound or paid elf iroin the

reels

08 and 09" so that said tapes need not turn such a sharp corner when entering or leaving the associated channels 30 in the blocks 32 as will tend to make said tapes bind loo or buckle. To this end I provide the curved guide member which, as best shown in Fig. 1 is secured to the top of the associated block 32, and terminates adjacent the reel. 09. Of course, there is U310 of these guide members provided for each pair of associated reels.

Filler strand iris-erasing means.hlounted on each upright standard is a bracket 98 securedthereto for both a rcrtical and horizontally swinging adjustment by means of a clamp screw 99. Said bracket extends laterally from said post and adjustably secured in the outer end thereof by means of a clamp screw 100 is a vertically arranged tubular stem 101. Said stem and bracket have tongue and groove connections by means of which angular turning movement between the two is prevented. Said tube is adapted to receive the filler strand 102 which passes out through its bottom end to be'laid in the shed provided by the ends of the stakes which are staggered. in the manner before mentioned. Said filler strand before it enters said stem passes over 7 guide rollers 103 and mounted, respectively on the bracket 98 and on a second bracket 98 (see Fig. 1) also ad'justably secured to said standard 47. The filler strands are carried upon supply reels (not shown) and pass up through a guide 105 mounted on a cross arm 10(lwhich connects the two posts 31 together, as shown in 1 after which said strands pass over suitable tension devices 107 carried on the top end of one of said standards 31. From said tension device the filler strands pass about the guide rolls 103-10 1 and'to therespective stems 101, as before mentioned. The bottom end of each stem carries a tapered or pointed stake spreader comprising upper and

lower members

108 and 109 respectively. As the staggered stakes approach said spreaded members they are caused to move further outwardly by engagement therewith to make a wider shed in which the filler strand which emanates from the bottom of the member 101 is laid. In this way,the filler strand is laid over one stake and under another and in some instances is laid in groups of courses over and under one or more stakes depending upon the operation of thestake staggering means as controlled by the tape or ribbon 10.

Filler strand packing means.It is, of course, important that the filler strand be uniformly packed in place so that the finished fabric be of a character suitable for use upon high class articles. To this end I employ substantially the same packing means as is embodied in the machine of my prior patent hereinbefore referred to so that I have not illustrated the same in detail herein nor will the same be described in detail but only in general. It will be understood that where the filler strand is laid between the stakes at the upper portions thereof it is necessary to pack the same from a polnt adjacent its ontrance in the shed between the stakes to a point cont iguous'the preformed fabric. As will be apparent, as the fabric is formed the extent of the packing varies. Said packing means includes a weight member 110' which is mounted for vertical sliding guiding movement between adjacent pairs of rods 9' and 10, by means of top and

bottom stud shafts

111 and 112, the bottom one of which carries antifriction rollers. In the bottom end of the weight member is provided a roller 113 which rolls upon a cam track member 114% supported by means of rods 115 from the top member 6 of the base. Said cam is of such formation as to impart the desired rise and fall to each weight at predetermined intervals as set forth in said prior patent, to elevate said weight and to permit the descent thereof once for every filler strand inserted. Said weight members are each provided near their bQtr tom end with a radial shaft 116, the outer end of which may be manipulated by hand when desired, either to test the packer, to permit release of the fabric or for such other purpose as may be necessary. To the inner end of said shaft is pivot-ally connected the bot- ,tom end of an upstanding packer arm 117.

Upon the top end of the packer arm 117, each of which extends up through an associated slot in the plate 8, is mounted a finger118 having a nose portion 118 which normally projects through the spaces between the fabric limiting members 16, as shown in Figs. 1'

and 2. Said packing arm is urged radially outward by means of a tension spring 119 as shown in Fig. 2. The construction just described permits the packer arm and finger to follow the members 16 of different forms as is necessary for the construction of differently shaped fabrics. The cam track 11 1 which elevates the packer weights and arms is stationary with respect to the frame portions 2 and 3 which are rotated by means now tobe described under the heading Driving mechanism.

The machine is driven from a main drive shaft 120 suitably journalled in the base 1 as shown in Fig. 2. Upon the outer end thereof are fixed and

loose pulleys

121 and 122 and secured upon the inner end thereof within the base is a bevel pinion 128. Said pinion meshes with a bevel gear 124 carried by a suitably journalled upright shaft 125. Upon the top end of said shaft is fixed a. spur pin ion 126 which meshes with a-spur gear 127 secured to the under side of the plate 7 In this manner, the frame parts 2 and 3 are given a rotative movement and the plate 22 together with the gear member 27 is driven in a direction toward the pointed ends of the Spreaders 108-109, as indicated by the arrow in' Fig. 9.

Secured to the non-rotative or stationary 2 plate 30 at a pointsubstantially diametrically opposite the bracket 89 are two; bearing held by means of the

brackets

130 and 131, respectively, the latter including an upright tubular extension 132 (see Fig. 13) which is spaced a suitable distance above the plate 30, In the outer end of the bracket 130 is fixed a bushing 13% in which is journalled the intermediate portion of a short upright shaft 135. To the bottom end of this shaft is fixed a pinion 136 which normally meshes with the bottom ring gear 28 and to the top end of said shaft is fixed a larger pinion 137. In the tubular extension 132 is a vertically movable or adjustable but non-rotative shaft 138 to the bottom end of which is keyed a Vertically elongatedpinion 139 and between said pinion and said sleeve is a second gear 140 which is adapted to be moved into and out of meshing engagement with the gear 137. Said gears are so proportioned that when the

gear members

139 and 140 are in their uppermost position the gear 139 will mesh with the ring gear 27 and the gear 140 will mesh with the gear 137 and when said gears 139 and 140 are in their lowermost position, the gear 139 will mesh with both ring gears 2728 and the gear 140 will be out of mesh with the gear 137. When the

gears

139 and 140 are in the full line position shown in Fig. 13 the bottom ring gearZS is driven in a direction opposite from that of the top ring gear and when said gears 139 and 1 10 are in the dotted line position, the ring gear 28 is driven in the same direction as that of said ring gear 27. e

llfeans are provided for manually raising and lowering said

gears

139 and 140 to change the rotation of the bottom ring gear each time a new fabric is started so that the desired tapereels 6868 and 69- -69, respectively, are driven in the proper directions after the associated clutches have been manipulated as before mentioned. Such means are as follows :-In the top end of the shaft 138 is pro vided a recess 142 in which two interiorlv threaded half sleeves 143 are non-rotatively pins 144, as shown in Fig. 14. The bottom end of a correspondin 1y threaded rod 145 has threaded engagement with said sleeve parts but said rod is secured against endwise movement in a manner soon to appear so that when said rod is turned in one direction the shaft 138 will move verti' cally downward and when said rod is turned in the other direction said shaft will move vertically upward, the

gears

139 and 1 10 moving in accordance therewith. The top end of the rod 145 is formed to provide a gear pinion 146. of a diameter larger than said rod. Said rod beyond the top end of said gear is journalled in the free end of a bracket 1 17 which is secured to and extends laterally from one of the standards 47. A clip 1 18 secured to said bracket and engaging the bottom of the gear 146 provides the other bearing for said rod. Said gear meshes with a larger gear 149 which is made rigid with a handle 150 journalled to the underside of said bracket 14? near its free end. It is apparent that turning the handle 150 in the proper directions, will act through the threaded rod to shift the

gear elements

139 and 140 into and out of the operative positions before mentioned.

It is apparent that the machine weaves upon diametrically opposite sides and that therefore the several duplicate parts bear the same reference numerals. In this manner, the time consumed in Weaving a complete fabric is materially reduced and the designs embodied therein are located diametrically opposite upon the finished article.

As the frame parts 2 and 3 are rotated in one direction the stakes are staggered in accordance with the humps and depressions upon the tape so that the filler strand is laid in the shed, under one or more adjacent stakes and over others as is apparent to produce the various designs which may be determined during the making of the tapes or ribbons 40. l i hen one fabric is completed it is not necessary to rewind the tapes upon the reel from which they were just unwound, but all that is necessary is to actuate the handle 83 to shift the reel clutches and then actuate the handle 150 to change the position of the gears 139 and 1&0 when the said tapes will operate in the oppositedirection. After one fabric is completed the top part of the machine from the plate 22 upward is removed, after which the fabric which is tubular in plan may be re moved by lifting it upwardly above the plate 17. A new band 20 with the stakes 21 is placed in position and the plate 22 and parts mounted thereon is replaced, after which the top ends of the stakes are positioned in the recesses 26 and under the springs 25-425? The filler strand may then be threaded over and under the stakes either by hand or by simply pulling a sufficient length of filler from the supply reel because when the machine is started the filler strand is automatioally laid in position and carried by the packers from the entrance position into a position closely adjacent the band 20. Continued rotation of the machinequickly lays in a suliicient amount of strands to form the fabric to the proper height. The machine is then stopped, the incoming filler strands severed, the plate 22 and associated mechanism raised. The packer fingers which rest upon the completed fabric, are then pressed inwardly by hand, thus lowering the associated weight so that it will rest upon the cam track. W' hen all the fingers are thus released, the fabric can be bodily raised and removed from the machine, the band removed from the stakes, new stakes then inserted therein, after which the band and new stakes thereon are replaced in position as before described. The plate 22 is again placed in position and the machine is again ready to start weaving the next fabric.
