SPECIFICATION forming part of Letters Patent No. 624,532, dated lllliay 9, 1899.
Application filed May 5,1898. SerialNo. 679,782. (No model.)
To all whom it may concern:
Be it known that I, JAMEs A. PARK, of White I'IouseStation, in the county of Hunterdon, State of New Jersey, have invented certain new and useful Improvements in Fence-Machines, of which the following is a complete specification, reference being had to may obviously be used for manufacturingthe fabric in factories.
My improvements consist generally in means for facilitating the forward movement of the machine and for steadying it in its upright position, in improved means for twisting the weft-wires, and in other details,which will be hereinafter more fully pointed out.
In the accompanying drawings, which illustrate my invention, Figure I is a perspective view of my improved fencing-machine in 0p erative position, the twister-wheels and bob-. bin-holders being omitted. Figs. 11 and III are side and top plan views, respectively, of the upper portion of Fig. 1, illustrating the manner of moving the machine forward. Fig. IV is a side view of several of the twisterwheels, bobbin-holders, and shafts. Fig. V is a central vertical section, enlarged, through two of the twister-wheels shown in Fig. IV. Fig.VI is a front View of three of the twisterwheels and apair of bobbin-holders. FigVII is a perspective view of two of the twisterwheels. FigVIII is aside view of part of the intermeshing cogs of the twister-wheels and the stem of the bobbin-holder in engagement therewith, the latter being shown in cross-section. Fig. IX is a perspective view, partly broken away, of one of the hollow shafts through which the warp-wires extend and which support the twister-wheels. Fig. X is a central longitudinal section through one of the bobbins and bobbin-holders. Fig. XI is a horizontal section, partly in plan view, taken centrally through the driving-shaft of the machine. Fig. XII is a section on the line .60 :0
of Fig. III. Fig. XIII is a vertical longitudinal section through the upper part of the forward standard of the machine, showing the wire-clutch mechanism. Fig. XIV is a central vertical section through the clutch shown in Fig. XIII. Figs. XV, XVI, and XVII are perspective views of parts of the clutch. Fig. XVIII is a front perspective view of the base of a bobbin-holder. Fig. XIX is a similar, view of one of the pivoted dogs for connecting the bobbin holder to the twister-wheels. Fig. XX is a similar view of one of the bobbin-clamps. Fig.'XXI is a similar view of one of the bobbins. Fig. XXII is a section,
on the line y y of Fig. II, and Fig. XXIII is a section on the line 2 z of the same figure.
Referring to Fig. I of the drawings,.1 and 2 indicate vertical standards, by which the working parts of the machine are supported. The rear section of the machine consists of a standard 2,longitudinally divided in the plane of the warp-wires, the two parts of the standard having opposing recesses, as shown, on 1 their faces, within which the hollow station; ary shafts 3, 3, and 3 are clamped by means of 13011334 passing through the standard and between each pair of shafts. The stationary shafts are each secured to one part of the standard by means of screw-bolts 5, having their heads within and flush with the interior of the shafts and the screw-th readed end passing out through the standard and secured by a nut. The drive-shaft 3 is mounted in suitable bearings, (shown in Fig. XL) and this.
arms 8, extending in a plane at right angles to the shoe, these arms being provided at their 7 outer extremities with a 'thumb-screw9, by means of which they may be drawn together to form a clamp. The arm may be connected to the side of the upright 2 by a suitablebrace 10. Beneath the arms 8 and extending at right angles to the machine is a shaft 11,
' screws and washers 26.
connected by pins 17 to cranks 27, secured to hinged to the shoe, so as to swing in a vertical plane, and carrying at its outer extremity the wheel 12. A curved link 13 is rigidly connected to the shaft 11 near its outer end and extends between the two parts of the arm 8, the set-screw 9 passing through the opening in the link. By means of the arrangement just described the wheel 12 may be arranged at-different angles, so as to maintain the machine in a vertical position under all conditions.
The standard 1 of the forward section of the machine also consists of two parts 14 and 15. This standard may be much shorter than the rear standard 2. As shown in the drawings, the part 15 extends below the part 14, and a large wheel 16, journaled in this extension, supports the standard. Certain of the hollow stationary shafts-as, for instance, the shafts 3 -are longer than the others and extend for ward between the opposing sides 14and 15 of the standard 1. These shafts pass freely through guides 20, which are secured to the (shown in section in Fig. XXIL) having vextically-projecting studs 23, upon which are journaled the ends of links or pitmen 24,'the latter being held in place by means of set- The links 24 are the opposite ends of a vertical shaft 28. The crank-arms 27 are each provided with a series of holes 18 for the reception of the link-pins, so that the movement of the links may be graduated. The shaft 28 is journaled in boxes 29, mounted upon the intermediate stationary shafts 3 and 3 and secured to a brace 30, extending between the shafts 3". Abeveled gear 31, rigidly secured to the upper part of the shaft 28, engages a beveled gear 32,
' supported in a suitable manner upon the uppermost journal-box 29. As shown in Figs. 1 and XII, the gear 32 has a central bore in its inner face, which engages with a projecting stud 33 upon the side of the journal-box 29, and its shaft 34is supported by an angleiron 25, secured to the top of the journal-box. A turning crank 36 is connected to the shaft of the bevel-wheel 32. The brace-bar 30 extends between the upper and lower ext-ended shafts 3" and is connected to the several journal-boxes, so as to make the machine more rigid. Its upper end 37 is curved forward, so as to clear the gear3l, and is secured rigidly to the uppermost shaft 3 v i It will be seen that by turning the crank 36 the shaft 28 will be rotated and the links 24 will be given a reciprocating motion through the medium of the cranks 27. At each semirevolution of the shaft 28, therefore,the standard 1 will be forced forward on its wheeled support a distance equal to the' diameter of the circle described by the crank-pin 17 from 'clusive,and described below.) These clutches slide freely over the warp-wires during the forward movement of the standard 1, but grip the wires whenever the standard commences to move in the opposite direction. It will be seen, therefore, that the continuous movement of the crank 36 through a complete revolution or a rocking movement will of necessity draw the rear section of the machine toward the front section,'since the latter cannot move backward. In this manner the movement of the machine is greatly facilitated, as the forward and rear parts of the machine are moved separately and steadily and no tracks are required. The manner of moving the machine forward is clearly indicated in Figs. II and III. By adjusting the crank-pins 17 the movement may be regulated so as to wind the weft-wires at different intervals. I
The clutches above referred to (illustrated in Figs. XIII to XVII, inclusive) consist each of a base-plate 40, having a projecting stud 41 at its lower extremity and a clip 42 at the top, and a spring-pawl 43, depending from a bearing-piece 44, the latter being eccentrically mounted upon a bolt 45, which passes through the base-plate and the upright 14 and is secured by a nut 46 upon the outside of the upright. The bearing-piece 44 is surrounded by a boss 47 and the latter in turn by a flange 48. The pawl 43 has on its lower and forward side a flange 49. A coiled spring 50 surrounds the boss 47, its ends resting within the catch 42 on the base-plate and the flange 49 upon the pawl. The end of the pawl normally hangs directly above the pin 41, and the pawl is adjustable vertically by means of the eccentric bearing 44, so as to adapt the clutch to wires of different gage. The warpwires pass between the pawl and the pin 41, and it will be seen that when the standard 1 is moved forward the pawls will glide over the wires, but will immediately and firmly engage the wires as soon as a backward pull is exerted upon them. The warp-wires are held against the pins 41in proper relation to each other by means of bolts 51, passing through thestandard 1 in advance of and .engagement with the pawl when the shaft has been rotated to the desired extent. As shown in the drawings, the stops are arranged so that the shaft can only make two and onequarter revolutions in either direction. The shaft is driven bymeans of beveled gears and 61, which are operated by a crank 62.
The twister-wheels, as shown in Figs. IV, V, VI, and VII, are each formed with front and rear skeleton plates, the front plate 63 being flat and the rear plate 64, as shown, extending outward toward the center. Each of the stationary shafts is provided with a collar 65, by means of which the wheels are maintained upon the shafts. In placing the wheels upon the shafts the collars G5 are first inserted within the respective wheels and the two are then slipped overthe end of the shaft. The collar is then secured to the shaft by a set-screw 66. The wheels will then be free to revolve on the shafts and the collars will prevent lateral displacement. The wheel upon the driving-shaft 3 is rigidly secured to the shaft by means of a key or set-screw. As shown in the drawings, one tooth is omitted from each of the twister-wheels, its place being supplied by two small separate auxiliary teeth 67, which extend slightly above the pitch-line. I designate the teeth 67 as F separate teeth because of the fact that they are separate both from each other and from the remaining cog-teeth. A web or flange projection 68, arranged in rear of the gear-teeth, extends across the space between each of the auxiliary teeth 67 and the adjacent cog. The
opposed faces 69 of the webs, and also the faces of the teeth 67, are curved to conform.
openings 73, arranged on either side of the axis and in line with the space 74 between the. auxiliary teeth 67.
The bobbin-holder or twister consists of a base-plate 75, having curved upper and lower edges 7 6 and 77, respectively, a tubular extension 78, projecting rearwardly from the center of the plate, a pair of parallel forwardly-projecting arms 79,arranged upon one side of the plate, and a similar pair upon the opposite side. The plate is also formed with two curved oblong openings 81, arranged near the top and bottom, as shown. Each pair of arms 79 and 80 is provided with registering perforations 82 midway of the arms and similar perforations 83 at the ends. In Fig. XIX, I have showua dog consisting of a bar 84, having a longitudinal groove 85, a pair of perforated ears 86, projecting from one end at an angle to the bar, and a peculiarlyformed head 87, projecting in a plane parallel to that of the cars 86. The head, as shown,
projecting partly above the bar84c, its outer surface 88 being curved or inclined and the faces 89 and'90 being straight. A narrow flange 91, having its outer face in the same plane as the face 90, extends downwardly from the bar. Two of these dogs are connected to the arms 79 and 80, respectively, by means of pivot-pins passing through the perforated cars 86 and the perforations 82 in the arms. When the dogs are in place, their heads will swing into the openings 81 in the base-plate, as shown in Figs. V and VI, the flange 91 limiting the movement of the dogs. The dogs are normally held in this position by means of springs 92, which are wound around the pivot-pins 93, one end of the spring resting within the groove and the other end of the spring being hooked around the stud-94 upon the end of a spool-clamp 95, one of which is pivoted in the ends of each pair of arms 79 and 80. It will be seen that the springs 92, while normally forcing the dogs into the openings 81, will also press the spool-clamps 95 toward each other. These clamps are each formed with a stud 96, which projects into the openin gin the bobbin 97, and a flange 98, which presses against the end of the bobbin with sulhcient force to prevent thespool from turning loosely and. too freely unwinding the weftwire. The wire is fed from the bobbin through the tubular stem 7 8 in the rear of the bobbin-holder. This stem I prefer to fitwith a screw-threaded bushing 99,0f brass or other metal different from theweft-wire, so as to avoid friction as much as possible. This bushing is formed with a flange 100. As shown in Fig. VIII, the stem 78 is hexagonal in cross-section, the sides 101 and 102 being adapted to fit against the wheels within the spaces between the cogs and the remaining sidesbeing formed in the shape of two cogs with their bases abutting. This stem is adapted to fit within the space 74 between the auxiliary teeth 67, and when the wheels intermesh at that point, as shown in Fig. VIII, the curved sides of the stem 78 will cut the cogs of the adjacent wheels upon the pitchline.
In assembling the machine the extensions 7 8 of the bobbin-holders are placed within the spaces 7 4, the base-plate of each bobbin-holder lying next to the flat front faces of the two adjacent gear-wheels. hen the spaces 74 are in alinement, the heads 87 of the dogs will project through the openings 81 in the baseplate of the bobbin-holderinto the rectangular openings 73 of the adjacent twister-wheels, as shown in Figs. V and VI. In this position the bobbin-holder will be anchored by stationary disks 105 upon the shafts which are fitted close to the base-plate of the bobbin. The disk upon the driving-shaft 3 is secured to the standard 2 by a sleeve, as shown, while the disks upon the stationary shaft are so: cured by set-screws to said shaft. These disks are cut away on their upper and lower consists of a part arranged at an angle to and edges 106 in the are of a circle corresponding with the curvature of the outer walls of the openings 81 in the base-plates of the bobbinholders. The bobbin-holder base-plate is in width about equal to the distance between two adjacent shafts, and the edges 76 are formed in the arc of a circle whose radius is approximately equal to the distance between the center of one shaft and the outside of an adjacent shaft.
It will be seen that when the wheels are in the positions shown in Figs. V and VI the dogs are maintained within the openings in the base-plate and twister-wheels only by the tension of the springs 92; but if the upper gear A in Fig. VI be assumed for the purposes of illustration to be the driving-gear rorating in the direction of the arrow the wall of the lower opening 73 in this gear coming into contact with the inclined surface 88 of the dog will force the latter out of engagement with said opening, whereas the wall in the upper opening of the gear B below coming into contact with straight face 89 of the lower dog will draw the bobbin-holder forward until the face 90 of the dog passes under the disk 105, adjacent to the wheel B. The bobbin-holder will therefore be disengaged from the upper wheel A and will be carried around by the wheel B, being held in engagement therewith by the flange 105 and the flange 100 upon the stem 78. In a similar manner the lower bobbin-holder will be carried around by the wheel B, and the weftwires will be twisted around the warp-wire passing through the shaft upon which the wheel B is mounted in the usual way. By reversing the direction of the wheels the bobbins instead of passing around the wheel B will pass around the adjacent wheels.
As stated above, I prefer to rotate the shafts about two and one-quarter times in each direction in order to twist the wires twice, the quarter-turn being allowed to compensate for backlash in the gears. This movement is li mited by the worm 56, pawl 57, and stops -59. (Shown in Fig. XI and previously described.)
In operation after the machine has been moved forward a step in the manner already described by turning the crank 36 the gears are operated to twist the weft-wires upon the warp-wires by turning the crank 62. The machine is then moved forward another step and the gears turned in the opposite direction to effect the twisting of the weft-wires upon the adjacent warp-wires, and so on.
It will be noticed that in my machine the bobbin-holders or twisters are in front of the twister-wheels and that the weft-wires are fed out centrally through the tubular stems 78, which at all times firmly rest within the spaces formed in the gear-teeth. At the time when the greatest lateral strain is exerted to, of means for moving both sections forward by independent steps, .substantially as set forth.
