DESCRIPTION OF THE PREFERRED EMBODIMENT The roller arrangement is shown generally and identified by reference numeral 10 in FIG. 1 and comprises an elongated hollow steel roller 12 supported on bearing support members 14 at spaced locations on a tufted textile machine frame to receive yarns thereagainst. Roller 12 is supported on respective short shafts 16 at each of the respective ends by means of steel plugs 18 fixed in the ends of the hollow portion of the roller 12 5 and each having a shaft hole therein. Shaft 16 has Short US. Pat. No. 3,089,442; Nix US. Pat. No.
SUMMARY OF THE INVENTION A plurality of yarns delivered to respective tufted textile needles are controlled by means of an eccentric roller operated against the yarns to vary the path thereof from a straight line to create a curvature which when released results in slack varying the amount of yarn fed. The problem of adjustment has been reduced in the present device by means of a simple repositioning of the roller on the shaft which supports the roller and easy set screw operation to accomplish this. There is no significant disadvantage of wear because there are no readily wearable moving parts and the initial construction and installation cost is relatively moderate.
An advantage of this invention resides in the quick and easy manner of changing the pattern control roller from one position to another to vary the pattern. A principle object of this invention is to provide a pattern control arrangement which can be quickly and easily changed from one position to another to vary the pattern. A beneficial arrangement is found in the construction whereby no machine shop operation is necessary to change from one pattern within the number of settings provided by the particular roller.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pattern control roller made in accordance with the present invention.
FIG. 2 is a cross-sectional view taken substantially along lines 22 in FIG. 3.
FIG. 3 is a cross-sectional view taken substantially along lines 33 in FIG. 2.
an elongated smooth portion 19 which is inserted in the plug '18 through the hole 20 and a reduced groove portion 24 which receives two set screws 26 threadedly engaging a threaded bore 28 near the end of the roller 12. Shafts 16 also include a series of elongated grooves or notches 30 spaced around the circumference of the shaft 16 and receiving therein a ball bearing 31 seated by a set screw 32 which is threaded into a tapped hole 34 near the end of roller 12, against a coil spring 33. Shaft 16 can be turned after set screws 26 are backedoff. Grooves 30 are numbered outside tube 12 for selective reference. Hole 20 is eccentrically located with respect to the center line of the roller 12 and the end of shaft 16 at the journal support member 14 is concentrically mounted in a bearing 36 on the frame member 14. Shaft 16 is attached to the bearing 36 by means of a dovetail locking groove arrangement comprising the plate 40 attached as part of the bearing having a protruding dovetail portion 42 thereon and a plate 44 attached to the end of shaft 16 and having a dovetail groove 46 therein which receives the dovetail protrusion 42 in the manner shown in FIG. 7 thereby connecting the end of shaft 16 to the bearing 36 on the frame member 14. Other rollers 12 may be added to and on other side of frame members 14 in the manner shown in FIG. 7 it being preferable not to use rollers that are too long due to the manufacturing expense and the deflection from the weight of the roller but rather a series of shorter rollers.
Each of the positions 30 represents a different cyclic motion based upon the cyclic diagram shown in FIG. 5 with the center of the bearing 36 representing the center reference point and the roller surface traveling in the pattern shown.
In FIG. 4 the path of the roller is illustrated diagrammatically from FIG. (a) thru FIG. (d) wherein the yarns are shown as numbers 50, 52 there being a plurality of yarns on opposite sides of and all along the roller 12 and as the roller 12 is driven by a power means in the counterclockwise direction shown the yarn 50 is moved from shorter length position shown in (d) thru the series from the right to left hand side until yarn 50 is in the longer arc shown in (a) and yarn 52 is shortened in a similar manner. Each time the roller 12 revolves the procedure is repeated and the amount of yarn is controlled by the position of the ball bearing 31 in the notch 30 on the short shaft 16 from the maximum position of eccentricity to the minimum position of eccentricity as illustrated in FIG. 5.
With reference to the illustration in FIG. 8, a typical tufted textile machine frame is designated generally by reference numeral 56 and comprises longitudinal frame members 58 and vertical frame members 60 on which is mounted the carpet spool 62 on a shaft 64 below the tufting bed 66 which contains the plurality of side-byside tufting needles receiving respectively a yarn 50 or 52 depending on whether it is on the front side or the back side of the roller 12 which is mounted on the frame members 14 in the manner previously described. The yarn 50 or 52 is delivered from yarn packages on bobbin frames and carried across rollers 68, 70 mounted on journals and frame members 72 and driven by a chain 74 carried by the end of roller 12 which in turn is driven by a chain 76 from a power source not shown. Observing the diagrammatic series in FIG. 4 and FIG. 5 in connection with the machine arrangement shown in FIG. 8 it is seen that as the roller 10 is driven eccentrically yarns 50 are moved from the extended positions shown in FIG. 4(a) to the position shown in FIG. 4(d) during which time yarn is released to the needles and the pattern is varied and the cycle is repeated each revolution of roller 10.
While I have shown and described a particular embodiment of this invention together with the suggested mode of operation this is by way of illustration only and does not constitute any sort of limitation on the scope of the invention since various alterations, changes, deviations, amendments, revisions, omissions and departures may be made in the embodiment shown without departing from the scope of this invention as defined by proper interpretation of the appended claims.
