ALVA L. KITSELMAN, AOF RIDGEVILLE, INDIANA.
WIRE-FABRIC MACHINE.
SPECIFICATION forming part of Letters Patent No. 592,931, dated November 2, 1897. Application filed J'u1y`22, 1896. Serial No. 600,149. (No model.)
To all whom it may concern:
Beit known that I, ALvA L. K1TsELMAN,'a citizen of the United States, residing at Ridgeville, in the county of Randolph and State of Indiana, have invented a new and useful Wire-Fabric Machine, of which the following is a specification. v
This invention relates to wire-fabric machines..
The main and primary object of the present invention is to effect certain improvements in machines for weaving wire fabric, especially for fencing purposes, whereby the same shall be entirely automatic in character to provide for the twisting of the weft-wires together or onto the lines wires, and also for the transferring or shifting of the spool-carrying devices from one twister-wheel to another.
The invention also contemplates improved means for propelling the machine with accuracy and despatch, whereby the mesh of the fabric being woven may be varied at will, accoi-ding to the character of the work, and as a general object it is the intention to provide a wire-fabric machine constructed in such a manner that all of the parts thereof may be readily assembled and replaced without the services of a skilled mechanic.
With these and many other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed. Y

Fig. 28 is an Fig. 14 is an enlarged detail vertical ysectional View of that portion of the machine IOO enlarged detail elevation of the catch device for the beveled gear drive-pinion.
Referring to the accompanying drawings, the numeral 1 designates an upright frameboard of a suitable height, according to the height or width of fabric or fencing to be woven by the machine, and said upright frame-board 1 is supported for travel over the ground at its lower end on the opposite parallel base-plates 2. The base-plates 2 are arranged at opposite side edges of the upright frame-board 1 and are provided near one end with short upwardly-disposed arm extensions 3, which are pivotally secured to the side edges of the frame-board on pivot screws or belts t, which permit the plates 2 to be moved at an inclination to the upright disposition of the frame-board. Immediately above the pivotal support t of the base-plates 2 the arm extensions 3 are provided with segmental slots 5, receiving the clamping-bolts G, mounted in the frame-board 1 and providing means for rigidly clamping the base-plates 2 stationary when adj usted. The base-plates 2 project beyond the front and rear sides of the upright frame-board 1, and the portions of said plates in front of the frame-board are somewhat longer than their rear portions, so as to steady the machine as it advances along the line of fencing or fabric being woven, and at the opposite extremities of the said baseplates 2 the latter are provided with short inwardly-disposed bearing-axles 7, on which are mounted the ground wheels or rollers 8, which support themachine for travel over the ground.
In connection with the wheeled support of the machine is preferably employed a groundtrack f), (illustrated in Fig. 2 of the drawings,) and which may consist of ordinary planking, and by reason of the adjustability of the wheeled base-plates 2 it will be obvious that such plates may be adjusted to suit the inclination of the ground without affecting the desired vertical disposition of the frameboard, which is quite an important feature in connection with wire fencing or fabric machines.
The upright frame board 1 is provided therein with a series of vertically-alined regularly-spaced openings 10, in which are detachably fitted one end of the hollow vertically-alined stationary spindles 11. The hollow vertically-alined stationary spindles 11 are arranged in a number equal to the greatest number of warp or line wires in connection with which the machine can be used, and each of said spindles 1 1 is provided in opposite sides, near one end, with the diametrically opposite notches 12,adapted to receive therein the opposite parallel side portions 13 of an open locking-key 111. The open locking-key 1l for each stationary spindle is substantially rectangular in form and is provided at one end with a circular portion 15 sufliciently large to be readily slipped over the end of the spindle projecting beyond the rear side of the upright frame-board, and at one side of the circular portion 15 for the remaining portion of its length the locking-key 14 tapers in thickness, so as to form a wedge to tightly fasten the spindle in place. It will be obvious that when the spindle is inserted through the opening 10 therefor, so as to carry its notched end beyond the rearside of the frame-board, the circular portion 15 of the locking-key is slipped over the notched projecting end of the spindle, so as to bring the opposite parallel portions 13 of the key in alinement with the side notches 12, and by moving said side p0rtions 13 of the key into the notches 12 and hammering the key so that it will wedge itself aga-inst the frame board and in the notches 12 the spindle will be drawn tightly to its proper position on the frame-board.
Each of the verticallyalined stationary spindles 11 is provided intermediate of its ends and at the side of the frame-board opposite the locking-key with an annular bearing shoulder or flange 1G, between which and the upright frame-board 1 is arranged a detachable bearing-bushing 17. The detachable bearing-bushing 17 loosely registers on the spindle 11 and bears at one end directly against the shoulder 1G, and at its end opposite the shoulder 1G the bearing-bushing 17 is provided with an annular bearing-flange 18, which rests flat against the front side of the upright frame board 1, and arranged to loosely revolve on the bearing-bushin g 17, between the shoulder 10 and the flange 18, is the cylindrical iianged hub 1f) of the toothed or gear twister-wheel 20.
In connect-ion with the mounting of the twister-wheel a very important feature to be noted is that the detachable bearing-bushing is a trifle longer than the length of the wheelhub 19, so that when the locking-key for the spindle is tightened, so as to draw the shoulder 1G against the bushing 17 and the latter against the frame-board 1, it is impossible to bind or wedge the twister-wheel, which will always be sufficiently loose between the lianges 1G and 18, so as to freely revolve on its spindle. This is of especial importance in assembling the parts of the machine together and in dispensing with machine-work in fitting the parts so that the twister-wheels will freely operate.
The locking-keys provide for detachably locking the spindles in place, whereby the same can be readily removed and replaced, and at their outer ends beyond the front side of the machine frame-board 1 the said spindles are provided with the bearing portions 21, which loosely receive thereon the central bearing-collars 22 of the combined guide and supporting disks 23, loosely arranged at the outer end of each spindle. rlhe combined guide and supporting disks 23 have the collars 22 preferably formed integral therewith and projected from one side, so as to loosely engage over the spindles, and at their inner edges the collars 22 are provided with a se- IOO IIO
ries of retaining-tongues 24, which are bent over and loosely engage with an annular bead or rib 25, formed exteriorly on the spindles near their outer ends. The disks 23 are used in connection with the spool-carriers for the purpose of guiding and supporting the outer portions of said carriers, as will be hereinafter described; but said disks are provided with central wire-openings 26, communicating with the interior of the spindles and designed to receive the longitudinal warp or line wires of the fabric being Woven by the machine. Y
Since each spindle has mounted thereon in the manner described a cogged or gear twisterwheel 20, ihese wheels are arranged in vertical alinement one abovethe other and the cogs or teeth of the adjacent wheels mesh, so that the entire series of wheels are geared together for a simultaneous rotation, and one of the intermediate twister-wheels 20 carries at its inner side a beveled gear-wheel 27, meshing with an adjacent beveled gear-pinion 28, mounted on a short drive-shaft 29, journaled in a suitable bearing 30, secured at the rear side of the upright frame-board l and having attached to its outer end a crankhandle 3l, which is grasped by the hand and turned in a continuous forward direction to provide for the simultaneous turning of all of the twister-wheels, as will be readily understood. Directly above the beveled gearpinion 28 is arranged acasing or box 32, provided in its outer side with a slot 33 and receiving therein a self-adjusting check-dog 34, provided with a lower beveled end 35, loosely riding over the cogs or teeth of the beveled gear-pinion 28 as the same is turned in a forward direction.
The check-dog 34' is raised automatically by the teeth of the pinion and drops between the teeth by gravity; but the lower end of said dog is beveled in a direction so as to ride over the teeth of the pinion only when it turns forward, thereby causing the dog to lock itself between the teeth of the pinion should the crank-handle be turned in a backward direction. The said self-adjusting catch-dog 34 is provided with an offstanding stop-pin 36, working in the slot 33 of the casing 32 and serving to limit the movement of the dog, while at the same time permitting the dog to be lifted out of engagement with the gear-pinion should it be found necessary during the operation of the machine.
The intergeared vertically-alined twisterwheels 20 are of a uniform size and are provided at diametric'ally opposite poi-nts with peripheral notches 37, and at the points where the notches 37 occur the cogs or teeth of the wheels are interrupted to leave spaces for the notches and provide for the proper connection of the spool-carriers 38 with the wheels, so that such wheels during their rotation will positively carry the spool-carriers therewith. rlhe spool-carriers 38 carry the weft or mesh wires, which are twisted together at the points of intersection or around thev longitudinal warp or weft wires, and, as is common in machines of this character, every alternate twister-wheel is active and carries a pair of spool-carriers, excepting, of course, the top and bottom wheels of the series, which at intervals carry only onespool-carrier `when the weft lor mesh wire is being twisted around the top, and bottom line-wires of the fabric, all of which is well understood by those skilled in the art.
Each spool-carrier 38 essentially comprises a substantially U-shaped frame-arm 39, provided at one side and at a point intermediate of its ends with an offstanding spool axle or spindle 40 and at one end with a pair of spaced parallel elliptical retaining plates 4l, connected together by a short rounded neck-piece v42,.which registers in the notches 37 of the end of the spindle about which the spool-carrier rotates. The circular bearing-head 44 at one end of each spool-carrier is provided therein with a central wire-gugde slot or opening 45, and at opposite sides of said slot or opening with separate wire-guide openings 46, all adapted to receive and form guides for the weft or mesh wire b, which is twisted together or onto the warp or line wire a. The weft or mesh wire Z9 is carried in quantities o n the wire spools or reels 46a, mounted to turn on the spool axles or spindles 40 of each spool-carrier, and in connection with the slot 45 and the separate guide-openings 46 in the `head 44 of cach spool-carrier it is to be ob- IOO IIO
servedA that lby passing the weft or mesh wire through the said slot 45 or either of the openings v46 the tension of such wire maybe partly regulated, according to the character of thcl work.
The offstanding spool-axle or spindle 40 of each spool-carrier is provided at one end with a squared locking-head 47, from opposite sides of which are projected the short locking-studs 48, which together with the head 47 cooperate with a sprin g-plate 49, which serves the double function of a spring-tension and locking-plate forthe spool 46a. The spring-plate 49 is bowed in a longitudinal direction and is provided with bent contact ends 50, which have a direct contact with one of the circular flat end heads of the wire-spool 4G, and at a point intermediate of its ends the combined tension and locking plate 49 is provided with a central squared opening 5l, at diametrically opposite side edges of which opening and communicating therewith are formed guide-notches 52, which pass over the studs 4S in itting the plate 49 on the axle 40 and in removing the plate. In adjusting the plate 49, after the wire spool or reel 4G has been placed on the axle or spindle 40 of the spool-carrier, the said plate 49 Ais brought to a position with the oppositely-located notches 52 in alinement with the short locking-studs 48. The plate 49 is then passed over the locking-head 47, and by then pressing on the central portion of the f plate, so as to force the same toward and against the adjacent spool-liead, the squared opening 5l is carried below the plane of the locking-studs 4S. Vith the locking-plate held in this position the same is turned with the spool until brought to a position at direct right angles to the position when first fitted over the axle 40, and when the locking-plate reaches this last position the opening 5l again registers with the squared locking-head 47 and the plate springs out against the inner sides of the studs 4S, with the opening 5l engaging over the head 47, thereby locking the plate 49 on the spool-axle 40 and preventing such plate 49 from turning with the spool or reel as the weft-wire is pulled off of the same. XVhen the plate 49 is locked in the position referred to, the same exerts a spring-tension against one side of the spool 4G, so as to retard the rotation of such spool sufficiently to place the proper tension of the weft or mesh wire wrapped thereon. Vhen it is desired to remove the plate 49, the saine is pressed inward out of engagement with the lockin g-liead 47 and turned until the notches 52 aline with the studs 4S, as will be readily understood.
The `engagement of the short neck-piece 42 of each spool-carrier with the notches 37 of the twister-wheels disposes the elliptical retaining-plates 41 of each carrier, respectively, at the front and rear sides of the twisterwheels, and as thus positioned the said vretaining-plates travel in contact with the guide plates or castings 53. The guide plates or castings are substantially V-shaped and are arranged with their apices or points projected into the rentrant spaces formed between the adjacent meshing twister-wlieels at opposite sides of such wheels. The said V-shaped plates or castings 53 are provided with the iianged attaching-feet 54, adapted to rest flat against the front side of the upright frame-board l, and certain of said attaching-feet 54 are preferably provided with the securing-pins 55, cast integrally therewith and engaging in previously-bored openings 56, formed in the front side of the upright frame-board, and it is to be observed that the said pins 55 not only assist in securing the guide plates or castings in position, but also form guides in assembling the parts of the machine together, so as to insure the guide plates or castings being fitted in true positions. Other ot the said attaching-feet 54 are provided with screw-openiiigs 57, which receive the fastening-screws 5S for iirmly fastening the guide plates or castin 0fs in position.
The V-shaped guide plates or castings 53 essentially comprise an outer segmental baseilange 59 and a main guide-flange 60, projected from the inner side of the base-flange 59, intermediate of its edges and at right angles thereto, and said main guide-flange G0 is provided with a fiat bearing-surface G1, arranged parallel with the main base-flange 59, it being observed at this point that the main guide-ange 90 is illustrated in the drawings as being of a substantial T shape, but this formation of the flange is simply for the purpose of imparting lightness to the casting, as it is simply necessary to provide a ila-nge (50, disposed at right angles to the iiange 59, so as to project between the pair of spaced retaining-plates 41 of each spool-carrier.
The plates or castings 53 are arranged in vertical alineinent on opposite sides of the vertically-alined series of twister-wheels and are of a uniform V shape, excepting at the extreme top and bottom of the machine, where for the upper and lowerniost twister-wheels of the series is employed a pair of segmental guide plates or castings 53, which, excepting for their segmental shape, are of precisely the same construction as the plates or castings 53 and serve to complete the circular guideways for the spool-carriers as they are rotated with the said uppermost and lowermost twisterwheels.
Referring more particularly to the circular guideways referred to, it will be noted that the V- shaped guide plates or castings are placed together as closely as possible, so that the segmental side portions of the directly-adjacent guide plates or castings will be arranged in the same circular plane, and thereby practically forni continuations of each other, and this arrangement being duplicated at opposite sides of each twister-wheel it will be obvious that a complete circular guideway for the spool-carrier is formed directly adjacent to and around the periphery of each twister-wheel. rlhe elliptical retaining-plates 4l of each carrier are disposed, respectively, at the front and rear sides of the twisterwheel carrying the saine, and said retainingplates are of a sufficient width so as to project beyond the cogged periphery of the twisterwheels and work, respectively, at the opposite sides of the main guide-flanges GO surrounding the twister-wheel. This disposition of the retaining-plates 4l ot each spool-carrier respectively at the front and rear sides of the segmental guide-flanges G0 surrounding the twisterwheel serves to retain or hold the spool-carrier in engagement with the twisterwheel so as to rotate therewith, and it will be further observed at this point that the outer segmental edges of the retaining-plates 4l ride in contact with the outer base-flanges 59 at opposite sides of the in ain guide-flanges GO, while the short neck-pieces 42 of the spool- IOO IIO
carriers ride in contact with the flat bearingsurface :Gliat'the -inner edgesfof the 'said mai-n guide-flanges 60, thereby completing a bearing-contact of the spool-'carriers with the guide plates or castings that serves not only to retain the spool-carriers properly in ensteady the spool-carriers and insure :a positive even running of the machine.
Every alternate guide plate or casting 53 in each vertical row of 4such .plates or castings is provided with ka pivot-collar 63, pivotally reeeiving the pivot-pin 6i at lone end of an os'- cillatory switch point or iinger'65, workingat the front side of the guide plate or cast-ing and havin gata .point intermedi-ate of its ends a connecting-pin `66, working in a'segmental slot 6.7, formed in the plate 0r casting-at one side of the pivot-collar and directly'adjacent to the point or lape-X of the casting. At each side of the vertically-'alined series 'of twisterfingers arranged, respectively, at diagonally opposite points of the wheel, as clearly illustrated in Figs. 5a and 6 of the drawings.
are tapered towardtheir inner swinging terminals and are provided with curved side edges 69, so as to readily guide or transfer the spool-carriers from one twister-wheel to another in the manner to be presently described.
vertical row of spindles and work in front of i the upright frame-board in rear of the twisterwheels and the guide plates or castings, and
each of the verticali y-reciprocatin g operatingbars is provided with a series of perforations 7l, loosely receiving one end'of the connecting-pins 6G 0f the switch points or fingers in front of such bar. ciprocatin g operatin g-bars 70are respectively pivoted at their upper ends, as at 72, to .the opposite extremities of an intermediate connecting-link 7 3, pivotally mounted intermediate of its ends, as at 74, on the upright frame-board near the upper end thereof and providing means for the simultaneous movement of the operating-bars in opposite directions, whereby all of the switch points or iingers in`one vertical row will be oscillated or moved in one direction ,while the switch points or iingers in the other vertical row will be simultaneously moved in an opposite direction In connection with the opposite vertical rows of the oscillatory switch points or Y They The two vertically-r'e- One of the vertical]y-reciprocatng operatv ing-bars 70 has iiXedly secured to the inner v side thereof at a point intermediate of its gagement with the twister-wheels, butalso to 1 upper and lower ends a substantially rectangular yoke 75, having straight upper and lower sides 76 and opposite curved end portions 7 7. The yoke 75 has arranged to work inside of the same a cam projection 78 -of substantially triangular` form and projected from one side of a toothed cani-wheel- 79, mounted on the inner end of a short stubsh'aft 80, turning in a bearing-opening 81, formed in the upright frame-board 1 and carrying on its outer end at the rear side of the upright frame-board ra pointer 82, working in front `of a numbered dial-plate 83, circular in shape and fastened on the rear side of the upright frame-board for the purpose to be presently referred to.
vThe toothed cam-wheel 79 works within a wheel-recess Si, formed in the front side of the -upright frame-board, and arranged in said lrecess in rear of the said wheel 7 9 is a bowed leaf-spring 85, which draws the pointer 82 firmly against the dial-plate 83 and takes up all slack in the mounting of the shaft 8O and vexerts a sufficient friction against the inner side of the wheel 7 9, so as to prevent the sarne from turning accidentally and thereby interfering with the operation of the machine.
` The said cam-wheel 79 is illustrated as be- The oscillatory switch points or Afingers 65 y ing provided with a peripheral series of regularly-spaced strike-teeth S6 and adapted to be engaged by the adjusting-pins 87, projected from the inner side of one of the twister-wheels 2O at diametrically opposite points of the spindle on which said wheel is mounted. By reason of employing a pair of Adiametrically opposite adjusting-pins 87 the cam-wheel 79 is moved a distance of two of its teeth at each complete revolution of the twister-wheel, and as the cam-wheel is preferably provided with eight strike-teeth 86 it will require four complete revolutions of the twister-wheels to .make one complete revolutio'n of the cam-wheel, during which complete revolution of the cam-wheel the switch points or fingers Vare adjusted twice to provide for two transfers or shifts of the spool-carriers, as will be more particularly referred to. Y
The cam projection 7 8, carried by the camwheel 79,- while of substantially triangular form, is provided with a single eccentricallydisposed contact-point S8 and a curved or segmental bearing portion S9, whichis concentric vwith the center of the cam-wheel '79. Assuming the said cam 78 to be in the position illustrated in Fig. 15 of the drawings Aand traveling in the direction indicated by the arrow, the contact-point 88 will ride against the lower straight side 76 of the yoke 75 and will lowersuch yoke, together with the operating-bar 70 to which it is fitted, such movement causing an elevation of the opposite op- IOO erating-bar by reason of the link connection 73. As the wheel 79 continues to turn under the adjusting influence of the pins 87, the segmental port-ion 89 of the cam projection 78 rides over the lower straight side 76 of the yoke 7 5 and serves t0 hold the operatingbars, and consequently the switch-points or fingers, in the position to which they were adjusted by the engagement of the cam with said lower straight side of the yoke 75, and the parts remain in this position until the contact-point of the cam projection reaches the upper straight side 7G of the yoke, when the reverse action or adjustment takes place. ly reason of the cam 7S holding the yoke 75 in its elevated and depressed positions for a portion of the time while the cam-wheel 79 is rotated means are provided to allow each pair of spool-carriers to make two complete revolutions with the twister-wheel carrying the same before they are shifted or transferred to the adjacent twister-wheels. This operation insures two complete twists of the weftwires around the line or warp wires or together before a transfer or shift is made.
The free swinging ends or terminals of the switch points or lingers (55 are thrown by the vertieally-reciprocating operating-bars 70 against the front circular guide-fianges 90, formed on the front sides of the twister-wheels and serving in conjunction with the switch points or fingers to properly guide the spoolcarriers while being rotated with the twisterwheels and also while transferring' or shifting from one wheel to another, and this is important to note in connection with the operation of the machine for weaving a line of fabric, whether for fencing or other purposes. As already referred to, in the operation of the machine every alternate twister-wheel is an active wheel, while the other twister-wheels carry no spool-carriers until the adjacent wheels have made two complete revolutions. Each active wheel, excepting, of course, the uppermost and lowermost, carries in its diametrically opposite notches 37 a pair of spoolcarriers which, when rotated with the wheel, pay out the weft or mesh wire as the same is twisted together at the point of intersection or onto the warp or line wires, as is well understood by those skilled in the art, and while the active twister-wheels are rotatin with the spool-carriers locked in their notches in the manner already described the switch points or fingers are disposed in such positions as to hold the spool-carriers in place until a shift or transfer is to be made.
lVith the spool-carriers rotating with each active twister-wheel it will be noted by a reference particularly to Figs. 5"L and G of the drawings that the switch points or fin gers at diagonally opposite sides of such twisterwheels are disposed in a position with their swinging ends or terminals respectively against the guide-danges 90 of the twisterwheels above and below the wheel carrying the spool-carriers, so that as the said active twister-wheel rotates the outer elliptical retaining-plates tl of the spool-carriers carried thereby strike against the guide-flanges 90 of the adjacent twister-wheels and also ride against the switch points oriingers contacting with such flanges and which deflect the said elliptical retaining-plate onto the segmental guide-flanges Gl im mediatelysurrounding the active twister-wheel. XV hen two com plete revolutions of cach active twister-wheel are made, the position of the switch-points is reversed, so that when the outer elliptical retaining-plates 4l of the spool-carriers carried by said wheel reach the circular guide-flanges 90 of the adjacent twister-wheels the swinging ends or terminals of the switch points o1' iingers will be in contact with the front circular guide-flan ge 00 of the said previously-active wheel,and will deflect the elliptical retaining-plates onto the segmental guide-flanges (il immediately surrounding the adjacent twister-wheels immediately above and below the previou sl y-aetive wheel, it being of course understood that as the twister-wheels rotate the notches 37 of such wheels come to a position where they register, so as to receive the short neck-pieces 42 of the spool-carriers.
In connection with the adjustment of the switch points or fingers and the transferring of the spool-carriers the pointer S2 and dialplate 83 have an important function, it being noted that the dial-plate 83 is provided with numbers corresponding with the number of teeth on the cam-wheel 79, so that the operator turning the crank-handle and facing the rear side of the wheel can tell by glancing at the pointer and dial when a transfer or shift of the spool-carriers is about to be made, so that the machine can be moved along to the desired width of the mesh before another twist is made, it being noted that the pointer and dial would indicate when the switch points or fingers are thrown immediately in advance of the transfer or shift of the spoolearriers from the active to the previously-inactive wheels.
To provide for propelling or advancing the machine and to regulate the size of mesh of the fabric being woven, a propelling device is employed that operates in conjunction with the warp or line wires of the fencing or fabric, and this propelling device essentially comprises a circular drum ill, provided with a peripheral wire groove 92, adapted to receive one complete wrap of the warp or line wire a, so that as the drum 91 is rotated in the manner to be described the machine will pull itself along on the warp or line wire. The rotating drum 91 is provided at its center with oppositely-disposed spindle projections 93, which loosely turn at their tip extremities in the bearing-collars (A, formed at one end of the angled clamp-plates 95, adapted to adjustably embrace opposite side edges of the upright frame-board l, so as to support the drum 91 for rotation at the rear side of the said frame-board. The drum 0l. is mounted IOO IIO
for rotation between' the parallel arms 96 of the angled clamp-plates, and adjacent to the. angled portions of said plates which embrace the opposite side edges and rear side of the upright frame-board the parallel arm portions 96 of said plates are connected by the clamping-bolts 97, which when tightened serve to rigidly clamp the plates 95 onto the upright frame-board and when loosened allow the clamp-plates and the rotary drum to be adjusted to the desired elevation, according to the height of fabric being Woven.
The rotating drum 91 is provided at opposite sides of its vertical center with the opposite internally-toothed ratchet-Hanges 9S and 99, respectively, the ratchet teeth of said flanges 9S and 99 being respectively disposed reversely to each other. The 'internallytoothedratchet-ange 9S at one side of the drum 91 is designed to be engaged by the points of a pair of diametrically opposite gravity check-dogs 100, pivotally mounted on the pivotpins 101 at the inner side of the stationary cap-plate 102, preferably formed on one of the parallel arms 96, supporting the drum and serving as a cap for oneside of the drum. The teeth of the opposite internally-toothed ratchet-flange 99 of the drum are designed to be engaged by a pair of diametrically opposite gravity adjusting dogs 103, pivotally mounted on the pivot-pins 104 at the inner side of a movable cap-plate 105, provided with a bearing-collar 106, loosely turning on one of the spindle projections 93 of the drum and carried at the inner end of a'hand-lever 107, which is adjusted 'up and down to provide for the oscillation of the plate 105 and the consequent movement of the adjustingdogs 103 over the ratchet-teeth of the flange 99. The gravity adj usting-dogs 103 are preferably provided at one side of their pivotal support with the finger-pins 108, projecting through segmental slots 109, formed in the plate 105, and adapted to be grasped by the fingersA of the hand to entirely disengage the points of the dog 103 from lthe flange 99 for a purpose to be hereinafter described.
The parallel arm 96 opposite the arm having the stationary cap-plate 102 is provided with a circular series of pin-openings .110, adapt-ed to receive an adjustable stop-pin 111, and said openings 110 are numbered on the outside of the arm to indicate the length of the mesh of fabric to be woven, and saidadjustable stop-pin 111 is adapted to limit the movement of the hand-lever 107 by engaging with a web or lug 112, formed on one side of the lever 107 and having a play between the movable cap plate 105 and the adjacent clamp-arm 96, as clearly illustrated in Fig. 16 of the drawings. the adjustable stop-pin 111, is also provided with vertically-ahmed diametrically opposite limiting-pins 113, which limit the extreme upward and downward movement of the lever 107, it being noted that the Web or lug The arm 96, carrying 112 is also designed to engage against the pins 113.
When it is determined what the size of the mesh of the fabric is to be, the adjustable stop-pin 111 is adjusted in the proper pin-opening 110 according as the mesh is to be a oneinch, two-inch, or other size mesh, and the pin 111 will positively limit the play of the hand-lever 107, so that such play will be fixed and uniform and thereby positively insure the making o f a fabric having a uniform mesh. When the hand-lever 107 is moved in one direction, the adj Listing-dogs 103 freely travel over the teeth of the ratchet-flange 99, but when the lever is moved in an opposite direction the points of the dogs 103 engage with the teeth of said flange and rotate the drum 91, thereby causing it to travel along the warp or line wire and carry the machine therewith. As the drum 91 is rotated in this manner the points of the check-dogs 100 freely ride over the teeth of the ratchet-flange 98 and engage with the teeth of said iiange to positively prevent the drum from slipping back and disturbing the adjustment of the machine, as will be readily understood, said dogs 100 therefore simply serving the function of checks to hold the drum to its adjustment.
In the use of the machine to provide for a positive and even movement thereof it is found desirable to employ a plurality of the propelling devices just described, and in the drawings are illustrated three of such devices at the rear side of the machine. The central one of the propelling devices has already been particularly described, but the other propelling devices, respectively above and below the central propelling device and designated by the numerals 91fL and 91h, respectively, are duplicates in construction of each other and of the said central device, excepting that the said upper and lower propelling devices ,are not provided with the construction for regulating the size of the mesh, this construction only being necessary with one of the propel# ling devices. The said upper and lower propelling devices are adj ustably clamped onto the frame-board substantially in the manner already described, but the operating-levers 107a thereof are shorter than the hand-lever 107 and are connected to each other and with said hand-lever 107 by a single continuous connecting-bar 115, provided with a series of perforations 116, adapted to receive the pivotpins 117 of the levers 107 and 107a according to the adjusted position of the propelling devices at the rear side of the machine.
By reason of the use of a connecting-bar 115 themanipulation of the hand-lever 107 of the central propelling device provides for the simultaneous operation of all of the propelling devices,so that the machine will be evenly moved along as the weavin g progresses, it being noted at this point that the warp or line wires are stretched to a tight tension and by having one or more tight wraps around the ro- IOO IIO
ISO
tating drums of the propelling devices causes the said drums to move along the wires by reason of frictional engagement therewith.
The provision of the finger-pins 10S is important in connection with the propelling` devices above and below the central propelling deviceas, for instance, the lower propelling device might feed along the wire a trifle faster than the upper propelling device and thereby tend to produce an uneven mesh. Should this occur, the linger-pins 10S of the lower propelling device would be grasped, so as to disengage the adjusting-dog 103 from the drum of said lower propelling device, so that said lower propelling device would not operate until the upper propelling device had been moved along suficiently to correct the uneven feeding, after which the adjusting-dogs of the lower propelling device will be allowed to again engage with the ratchet-teeth of the rotat-ing drinn.
Modifications of the machine might be observed, such as illustrated in Fig. 27 of the drawings, in which figure is illustrated a modification of the stationary spindles for the twister-wheels. In this modified construction the spindle ll is illustrated as being suffieientlylarge to receive therein a barbed lin ewire should wire of this character be used in weaving the fabric, and said spindle is also closed throughout its entire length, so as to leave no edges to be engaged by the barbs or wire, and at one end the spindle has detachably fitted thereon a flared mouthpiece 1lb, which serves as a guide for the barbed wire to prevent its catching on the end of the spindle which moves along such wire.
Other modifications of the machine may be observed and various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
