Cross reterenceis-here made to my pair of stake gripping blocks embodied in pending, application Serial No..5t,l39 filed v Sept. 14, 1925, wherein certain matter herein shown but ynot claimed, is shown and claimed ranged tliat even though the stake be slightlyk bent or crooked, it will insert the stake into i the shed, and. in the forward movement of the iabi'ic, the stake is straightened so that the fabric is regular. Thereafter the fabric passes between coacting rolls having longitudinally.y extending angular corrngations lill) which accurately form the strands upon the stakes after which the finished fabric is wound upon a roll or mandrel.

Referring now in detail to that embodiment of the invention illustrated in the accompanyino' drawings; the machine includes upright spaced side pla-tes or frames. 1 and 2, respectively, of suitable form. Said side plates are held in the desired spaced relation by means of a front plate 3 and a rea-r tie rod l and if desired other members may be arranged between said front platev and the tie rod to assist the same as is apparent. The side plates or frames include near their forward ends, upright extensions 5 5 and in each of said extensions is formed a rectangular opening 6, closed its front end by a standard 7. Journalled in the rear portions of the said side frames is the main drive shaft 8 which is driven by suitable belting (not shown) and from which the associated mechanisms of the `machine are driven, as will later appear.

Fixed to the rear sides of both standards, in the median plane of the rectangular openings 6, is an edgewise disposed plate 9. rThis plate is provided with a plurality of holes or openings 10--1O therein (see Fig. 6) arranged in different horizontal and vertical planes so as to bring them all into closely spaced adjacent planes, longitudinally of said plate. rlhe warps of the finished fabric on the filler strand members 11-11 and said warps or strands are passed through said openings 10 and to prevent undue abrasion on said strands, the front ends of said openings taper outwardly (see Fig. 6). After said warps or filler strands proceed beyond said plate they occupy closely adjacent vertical planes as is apparent.

At the rear of the opening 6 of each side frame member, are fixed top and bottom cross bars 12 and13, respectively, of angle bar cross section with their vertical flanges 111 at the front and in alignment with each other. In the front face of each vertical flange is provided, longitudinally spaced, vertically disposed grooves 15 as best shown in Fig. 111. Spaced forwardly of said cross bars 12 and 18, are top and bottom transverse bars 16 and 17, respectively, which are rectangular in cross section and are vertically reciprocable toward and away from each other. ln the rear surface of the' transverse bars 16 and 17 are formed longitudinally spaced vertically disposed grooves 18-18 and on the top surface of the top transverse bar 16 and in the bottom surface of the bottom transverse bar 17 is fixed a shoulder' plate 19, each having a portion projectino' rearwardly beyond the plane of the rear face of the associated bar. 2O and 21 indicate, respectively, top and bottom transverse bars arranged above and below the frame connecting

cross bar

12 and 13 in The extreme vends of the bar 17 extend into the openingsv G in the side frame

mem# bers

1 and 2 and are eachthere provided i with an upstanding rael-r bar 24 (see Figli) while the ends of the bar 16 terminate short of said openings 6 and are each there provided with a rack bar 25 facing in opposition to the rack bar 24. Ai wear 23 suitably journalled in the machine frame side members meshes with and operatively connects said rack bars together so that they move in opposition to each other. Each rack bar 25 has sliding bearing against a guide bar 2G arranged vertically of the associated opening 6 (see Fig. 5).r

Secured to the bars 2O and 21 respectively, yis a plurality of filler strand manipulating members 27, one of which is best shown in perspective in F 12. Each member 27 is in the form 'of an L-shaped block like body 28 having a head 29 at its top end by means of which it is attached to the bar 20 by screws 30. rEhe bottom end of saidmember has a right angular extension and insaid extension and part way up said body portions are grooves or recesses 31 which define spaced plate like parts 82. The grooves and plate like parts are so relatively disposed as to provide a platelile part on one side of the body and a groove like part on the other side of the body. rlChe bottom edges 83 of said plate like parts are finished off on an angle less than a right angle and is inclined upwardly from the rear side of the body 28 toward the front andvon said rear side of the body part is formed a tongue or 3a'- which has sliding' guiding bearing in one of the grooves 15 in the cross bar 14.

`lliounted on the bar 21 is a plurality of filler strand manipulating members 27 which occupy a position reversed end for end-with respect to those on the bar 20. Associated with the bars 16 and 17 are filler strand manipulating members 27a which are identical with respect to the members 27 with the exception that they have no head parts 29 but have a flat end 29a as shown in Fig. 13. The members 27 a associated with the bar 16 occupy a position reversed end for end with respect to those associated with the bar 17 and the flattened end parts 29- thereof engage against the overhanging parts of the shoulder bars 19-19. Then all of said members 27-27a are in their respective positions, the plate parts 32' of said members associated with the bar 20 are locatedl in the same plane as the plate parts 32 of the llltl members 2721 associated With the bar 17, which plane is the plane of the recesses 31 of the other members 27 and 27L associated with the

bars

21 and 16, respectively. Likewise the plate parts 32 of the last mentioned members 27 and 27n are arranged in those planes which are coincident With the planes of the recesses 31 in the first mentioned member 27 and 27L associated vvith the bars 2O and 17 respectively. ln threading7 the filler strands through the` block of the manipulating device, said strandsvare disposed between thc angular ends 33 ofthe plate portions of the respective manipulating members and in the reciprocation there of, the strandsare free to follou7 said plates which are movable in the grooves 31 ofthe associated plates as before described. TWith the ends 33 of said blocks disposed in a plane less than a right angle to the body parts thereof, at no time Will all of said ends be arranged in the same common plane but said ends will overlap one another so that thestrands are at no time in a position wherein t1 may become displaced laterally or pinched or otherwise engaged by the laterally adjacent plate parts. As alternate strands are moved in one direction, the intermediate strands are ymoved in the opposite direction, so as to form a shed into which a stake 11a is inserted and after insertion of one stake said strands receive a reverse movement to lock said stake in place and to form a new shed into Which another stake is inserted and so on as best shown in Figs. and 11 respectively. n

The stakes indicated by the numeral 11L and which are the vvefts in the finished fabric are fed into the sheds as they are formed by continuously rotating top and bottom rollers 35 and 36 (see Fig. 15) suitably journaled'in the opening 6 of the side frame member 1, and geared together. T he top roller has a pulley 37 associatedivith 1tl which is driven by a belt 38 from a motor 3S). The sole function of saidmotor which is mounted on the extension 5 of said frame member 1 is to drive the stake feedingl mechanism and stakes are delivered to said feed rollers from a suitable hopper or magazine as Will later appear.

The preformed fabric passes overthe top of a transversely extending` horizontal roll 4() With which a second and similar roll '41 is associated, the fabric following about a portion of said rolle() and then in between both said rolls and is led olf the bottom of the roll 41 to a Winding roll or mandrel at the rear of the machine. The

rolls

40 and 41 which are fixed on associated shafts 40" and 41a respectively, journaled in the

side frame members

1 and 2, have longitudinally extending corrugations 42 (see Fig. 8) on their peripheries Which corrugations have angularly disposed surfaces as distinguished horizontal plane o f the main drive shaft'S but forwardly thereofand parallel thereivitli is a driven shaft 43 suitably journalled inthe

side frame vmembers

1 and 2. On said shaft adjacent the 'inner surface of the side frame member' 2 is a gear'44 which meshes with a. pinion 45 on the ma-in drive shaft. Gn that end of the shaft 43 Without the side frame member 2 is .provided a crank disc and arm 46 and upon said crank arm is journailed one end of a connecting rod 47 (see .Fien

The other end of said rod is operatively connected to a swinging arm 48 loosely mounted on the shaft 41- associated With the corrugated roll 41.v Fixed to the end of the shaft 41a adjacent the swinging' arm 48 is a ratchet Wheel 49 and adjacent said ratchet wheel is a gear 50 Which meshes With and drives a similar gear 52 on the c rresponding end of the shaft 40a associated with the corrugated roll 40. The swinging arm 48 carries a pavvl 48a normally engaged with the ratchet. W'hen'the shaft 43 is driven it is apparent, a step by step rotative movement is imparted to the shafts 40u`and 41@l vnd to the rolls thereon.

Secured to the shaft 43 adjacent the gear 44 is a sprocket 53 which through a chain '54 drives a similar sprocket 55', joilrnaled on a stud 56 fixed lto the side frame mem- 13er 2. arranged in'the vertical plane of but below that of the rack bar 25. Rotative with said sprocket is a mutilated gear 57 and said gear meshes with an associated mutilated gear 58 fiXed on a horizontal shaft 59 arranged vertically above the stud 56 'and journalled at its ends in the

side frame members

1 and 2. The

gears

57 and 58 are so formed that for each revolution of thegear 57 the gear 58'receives ahalf of a revolution. aired to the ends of the shaft 59 are eccentrics 6G and associatedstraps 61 and said straps are pivotally connectedto vthe rack bars25 of the strand manipulating and shed forming devices to impart the .desired movement thereto. as before described. Also fixed on the .shaft 43 is another sprocket 62 which through a kchain 6.3 drives a similar sprocket secured to a horizontal shaft in the horizontal plane of the shaft but located at the front end of the machine. the shaft' 65 being suitably j ournalled in said

side frame members

1 and 2.

l'lO

(ill

y which is in the form of a tubular sleeve mounted at its ends in the grooves G7 of end plates 68 and (39, respectively, said sleeve being split longitudinally to provide a slot l0 therein. The end plate v68 is fixed to a stub shaft 71 journalled in a suitable bearing T2 fixed on an extension 1a on the rear end of the side frame member 1, while the end plate 69 is fined on a similar stud shaft 73 journalled in a suitable bearing fixed on an extension 2 on the rear `end of the side frame member 2. The purpose of the slot 70 is to permit the insertion of the free end of the formed fabric to operatively connect it to the winding roll so that in the forma-- tion of the fabric, the saine will be wound upon said roll. rllhe stub shaftl 71 includes an extension 71"L of reduceddiameter and loosely mounted on the rsame adjacent the shoulder 71D formed by the parts of different diameters of said stubv shaft is a sprocket ill. Said sprocket is driven by a. chain 75 from a similar sprocket 76 mounted on that end of the shaft dla which extends beyond the side frame member 1. also mounted on the reduced end 71*L ofthe stub shaft 71 is a friction. slip clutch 77 which includes a plate 771 loose on said reduced end and a second plate 77 keyed to said reduced end 71 but capable of a limited endwise movement thereon, disc 77 of liber or the like being interposed between said plates. Said plates are held in close engagement with the liber disc by an expansion spring 78 which surrounfL s the extreme end of said reduced portion Z12L and abuts at one end against the plate Z7 and at its other end against a member 79 mounted on a bolt 80 threaded into said end portion 71a. lt is apparent that in the step by step rotation of the shaft 41a a similar movement is imparted to the winding roll and as the material wound thereon increases in diameter, the clutch 77 will slip to accominodate this increasing diameter. rlhe winding roll is so constructed that when a su'l'licient amount of fabric has been wound thereon, said sleeve 6G may be removed from the

end plates

68 and 69 and another one substituted in its stead.

In connection with the means for inserting a stal-re into the shed. which means includes the

rolls

35 and 36, l provide a means for feeding` the stakes 11a one at a time from a magazine or holder in proper timed relation to the forming of the successive sheds and such means are as follows: Projecting laterally from the end frame member 1 near its forward end is a frame extension 82 (see Fig. 1) which includes along its forward portion a horizontal flat plate 83 having screw threaded openings 84 therein. That said end frame member 1, said bolt also passing through the proper hole Si so that the position of the magazine may be easily adjusted to the length of the stakes to be used, which, of course, also approximates the desired width of the finished fabric. A

plurality of stakes 11a are placed with their outer ends in bunched relation in said magazine andthe forward portions thereof passed between two vertical plates 88 and 89 which plates are spaced apart a distance to provide a slot 90 equal to substantially the diameter' of the stakes employed. Said plates are located nearer the inserting rolls 353-38 than the magazine 8G and are supported from the rails or guides 235 by brackets 91, with the bottom ends of said slot forming plates 88H89, spaced above the guides 85. l/Vhen said stakes are in the magazine with their forward portions posi.- tioned in the slot 90, one above the other, they will assume a fan shape-like formation. lhe extreme forward ends of the stakes engage with a guide plate 92 of curved form and suitably supported in a substantially vertical position adjacent the frame member' 1, said guide plates having guide rods 93 which prevent said extreme ends of the stakes from flexing laterally thus holding them in the desired plane. ln the bottomend of said guide plate 92 is formed a round opening 9d (see Fig. 15) which is located in the horizontal plane of the peripheral meeting parts of the stake inserting rolls 35-36, which plane' is substantially coincident with the plane of the bottom ends of the slot (SO) forming plates 88 and 89, respectively.

Means are vprovided for gripping the bottom-most stake in the slot and for inserting its inner end through the opening 94 into and between the rollers 35-36 to be fed into the shed formed by the strands and such means are as follows z-Slidable on the rails or guides 85 between the. slot forming plates S25- 89 and the guide plate 92 is a reciprocating block 95 and pivoted on said block as at 96 is a pair of outwardly ex'- tendingand normally diverging links 97-97- Said links are pivotally connected to link blocks 98-98, one of whichis shown in'perspective in Fig. 18 which yblocks are pivoted on a common vertical axis 99 mounted on the inner end of a carriage 100 slidable on said rails or guides 85. Said carriage comprises top and

bottom plates

101 and 102, the longitudinal marginal parts of lili) which embrace opposed inner portions yof the rails A--85 andsaid plates are secured together by coacting bolts and springs-103 which act to draw said plates together and provide a frictional clamping action on said rails. Each link block 98 carries a gripper jaw..104 and, on the inner end of one awv is lsecured aftransverse bridge or guard plate 105. The top edge of said guard plate terminates short-of the plane of the top surface ofthe jaw blockso that whenl said jawsolose they can only grip one stake at a time. l I .Reciprocating movement is imparted 'to the block by a connecting rod 106, one endA of which is pivot-ed at 107 to an eXtension on the bottom of said block and the otherend of which is connected to a crank pinv108 on a disc 109 fixed on a horizontal shaft 110 journalled in and extending transversely of and below the extension frame cating movementftowardthe rollers 35`33 will loel impartedy to the. block 95. Said movement of said block-is resisted somewhat by the frictional engagement ofthe carriage with the rails 85-85 with the result that the inner ends of the links 97 97 are caused to `movetoward each other imparting a similar movement to the inner ends of the jaw blocks 98. As said jaw blocks carry the gripping jaws 104, said jaws will grip that stake resting on the guard plate and in the further forward movement of said block 95 will overcome the frictional resistance of the carriage 100 so that said stake is' fed through the opening 911 in the guard plate 92 into and between the feed rolls"35`-36 to be inserted thereby into the shed formed by the strands, as lbefore mentioned. In the rearward reciprocation of the block 95, the links 97 and jaw blocks 98 will open up due to the resistance offered by the carriage 1-00 and in the further movement of said block, the resistance of the carriage is overcome so that all parts are returned to their normal starting position. v

ln the forward movement of the block 95 means are lprovided to engage the stakes near the bottom end of the slot 90 between the plates 881-89 so that no more than afsingle stake is engaged by the jaws 104 and fed to the rolls 85 3G. Said means includes an inverted bell crank leve-r which is pivoted to the plate 88 as at 116. The-vertical arm 115@A is adapted to swing towardrand. away from the slot I90 and-is so formed as to` normally engagey the Vnext tothe bottom stake fin said 4slot sov that it cannot descend.

9 in the outward .withdrawal oftthebottommost stake. The horizontal arm 115b 'of said levery projects laterally Abeyond the plate 88 whereitvis connected by-links 117 with the free end of a lever '118.' Said lever is 1ocated belowfthe rearmost -rail 85 whichicarriesfa depending bracket 119 to lwhich the other endfof the lever 118 is pivoted.- The free end rof said lever which is roundedofl' normally engages upon a`v roller -120 coincident withrthe connection 107 between ythe block `95 and connecting rod 106, A spring 121 (see Fig 15.) which is connected atrone end to aipart of the machine frame and at its other endis connected to said lever, normally kurges said lever into engagement with't-he roller 120. However, when said block 95 is moved towards the rollers235-36as .before described, the lever 118 is left unsupported so that it moves downwardly, thus rocking the .bell crank lever 115 the vertical arm of which willacton the stakes as before described. -In the reverse movement of the block 85 the roller 120 will again engage the lever 118 andwill move it upwardly against the action of the spring 121 when the ver tical'arm of thebell crank lever 115a swings away'from.. the slot 90 under the action of a spring 122eonnecting the horizontal arm of the bell'crankwith the plate 88 so thatfthe now` bottommost stake is presented to the gripper jaws 104, the link 117 being made in two parts to provide movement. ,f l 'i ln many instance-s, the stakes are not Ipei'- fectly straight but are slightly bent and some timessaid stakes arevslight-ly oversize or undersize' and-if inserted-into the shed in its bent condition it is apparent that an irregular-fabric will resultwhich will not meet the requirements of a lirst class fabric. To overcome such a condition I provide means to straighten the stakes and preferably at aftime after `insertion into the fabric and suoli means are as follow-sz-Above the roll 10 and in vertical alignment with the axis ofl its shafti's provided a non-rotative but endwise movable shaft 125 and above said shaft and spaced equal distances on each lside of the plane 'thereof' are rock shafts 126 and'127, respectively, which are journalled at their-ends in the upright extensions 5 of the side frame '

members

1 and 2. Fixed on said rock shafts are segmental o'ears'126a and 127, respectively, which are offset with respect to each other.- The gears 126 mesh with sets of

segmental gears

128 and 129, respectively loose on the non-rotative shaft enough latitude in 125. Fixed toand connecting the gears 128L is a plate 128?l while a similar plate 12921v is fixed to and'connects the gears 129 and said plates are so arranged that in one .position of said-.gears128-129 they substantially meet in thevertical fplane ofthe axis 'of the shaft 125, asbest shown in Fig. 8.` On the under side-of each,- plate. is a strip member 130 which carries depending lingers 131. Said fingers extend transversely of said plates and are spaced suitable longitudinal distances apart. As the Woven fabric reaches the `plane. of the shaft 125 said blocks 128"L and 129il are rocked towardy each other, the fingers 181 entering' the spaces between alternate strands on the top surfaces of the stake to engage the stakefrom opposite sides and bring all parts thereof into the same plane so as to straightenthe stake after which the blocks are rocked in the other direction into an open position as shown in dotted lines in Fig. 8. Of course, as it Will be understood, this stake straightening operation is carried'on when the roll 40 is at rest which period is on the back stroke of the paivl 48 before mentioned.

A short endvvise movement is imparted to the shaft 125 so that said fingers may operate upon each successive stake, the end- Wise movement being` equal to the diameter of a filte strand. This endvvise movement is essential because it must be borne in mind that said fingers operate in the plane of the strands and that the strands pass over one stake and underthe next and if said endWise movement was not provided for said fingers they wouldv directly engage portions of fille." strands passing; over said stakes. Endwise movement in one direct-ion is imparted by means of an arm 135 secured on the extreme end of said shaft youtside the frame member 2 and this arm carries a roller 136 adapted to be engaged by radial vcam teeth'137 fixed to the face of the gear 52. Movement in the other direction is imparted to said shaft' by a helical expansion springllS (see Fig. 7) which is interposed between a collar 139 fixed on said shaft and liiearing sleeve 140 foi-nrl ingr a part of the end frame extensions 5 and through which said shaft has sliding bearing. Movement in this last direction is limited by a second collar 141 fixed to the shaft 125 between the arm 135 and said bearing; sleeve 140. The gears on the 'various shafts are of such length as to still main tain 'their meshing` engagement in the ree ciprocation of the shaft 125.

Rockingy movement is imparted to the shafts 126 and 12iw Which carry meshing

gears

126 and 127C' at their extreme ends (see 3) as folloivs:-Secured to the shaft 12S near the end frame member 2 is an arm 145 to which is connected the rear end of a connectingl rod 146. The other. end of said rod is'connected to a crank pin 147 adjustably mounted in a slotted disc 148 f carried on the inner end of a short horizontal one direction is imparted to the shaft126 Which by reason of the gears 126ic and 127 C imparts an opposite rocking movement to the other shaft 127 The machine may be operated to produce a fabric of a Width substantially equal to the length of the roll 40 or less than that when .so desired. fabric be desired, the number of strands employed are reduced accordingly and the length of the stakes Wili'be made in proportion and an L-shaped stop member 155 fixed to the portion 14 of the frame member 12 is provided, as best shown in Figi'. 1, against which the ends of the stakes Will engage as they are inserted into the shed.

As the operation of the parts, as Well as their construction'has been clearly described, itis not thought necessary to again go into a detailed description of said operationbecause the same will be indeed apparent to i thosefamiliar with the art.

rllhe machine is fast andpositive in its operation so that production is attained Without sacrificing the quality of ythel product. rll'he stakes need not be carefully positioned for feeding' into the sheds, and even if said Should a much narrower v stakes are bent When fed -into lthe sheds,

they are straightened While in the fabric.
