PHJE STZTCHEIG Joseph Lewis tCard, Chattanooga, Tenn, assignor to Singer-Cobble, Inc, Chattanooga, Team, a corporation of Delaware Filed Sept. 15%, 1957, Ser. No. 684,836 (Zlaims. (Cl. 112-79) This invention relates to a multiple needle tufting machine and more particularly to a tufting machine for simultaneously forming rows of cut pile stitching and rows of loop pile stitching.
Heretofore tufting machines have been designed for forming either fabric of loop pile or fabric of cut pile. Because the inherent characteristics of a loop pile machine are entirely different, and in many instances opposite, from the characteristics or a cut pile machine, attempts to combine the characterisics of the two machines to form both loop pile and cut pile in a single machine have not been successful. In a conventional loop pile tufting machine, the loop pile hooks are pointed in the direction of fabric feed to permit the loops to feed off the hooks, whereas in a conventional cut pile tufting machine, the loop hooks are pointed in a direction opposite to the fabric feed in order to hold the loops until they are cut by a cooperating cutting mechanism. Moreover, the timing of the reciprocating movements of a loop pile hook and the timing of a cut pile hook are just the opposite since a loop pile hook must be moving backward to engage a loop formed by a descending needle at the same moment that a cut pile hook must be moving forward for the same purpose. Attempts have been made to design a machine that would form both cut pile and loop pile by having two sets of needles and two independently driven and independently timed sets of hooks, one for out pile and one for loop pile, spaced to stagger the rows of cut pile tufts between the rows of loop pile tufts, and vice versa. Such a combination has the same effect as providing a cut pile tufting machine and a separate loop pile tufting machine through both of which the base fabric fed progressively. Such attempts have proved highly unsatisfactory.
It is therefore an object of this invention to overcome the disadvantages enumerated by providing a tufting machine which will form rows of cut pile and rows of loop pile without employing dual mechanisms.
Another object of this invention is to provide a tufting machine for simultaneously forming cut pile and loop pile in which the loop pile mechanism is of novel construction.
Another object of this invention is to provide a tufting machine for forming cut pile and loop pile in which the out pile hooks and loop pile hooks are mounted in a single hook bar.
A further object of this invention is to provide a tufting machine for forming cut pile and loop pile in which the cut pile hooks and loop pile hooks are pointed in the same direction, opposite to the direction of fabric feed.
Another object of this invention is to provide a tufting machine for forming cut pile and loop pile in which the cut pile mechanism and loop pile mechanism have the same timing and reciprocate in unison.
Another object of this invention is to provide a multiple needle tufting machine for simultaneously forming rows of cut pile stitching and rows of loop pile stitching with selected needles and havin yarn feed control means for forming loop pile of various heights according to a predetermined pattern.
A further object of this invention is to provide a multiple needle tufting machine to simultaneously form rows ice of cut pile and rows of loop pile for selected needles and having yarn feed control means for selectively forming loop pile higher than the cut pile and loop pile lower than the cut pile.
Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the drawings, wherein:
FIG. 1 is a perspective view of the invention;
FIG. 2 is a section taken along thelines 22 of FIG. 1 disclosing the cut pile hook and the loop pile hook in their forward operational positions;
FIG. 3 is a view similar to FIG. 2 in which the cut pile hook and the loop pile hook are in their withdrawn operational positions;
FIG. 4 is a perspective view of one type of loop stripping finger associated with a loop hook;
FIG. 5 is a perspective view of a modified form of loop stripping finger associated with a loop hook;
FIG. 6 discloses a modified form of loop hook; and
FIG. 7 is an enlarged view showing the operation of the loop pile hook and loop stripping finger in FIG. 3.
Referring now to the drawings in more detail. FIG. 1 discloses the operating parts of the invention, with parts broken away, as they would appear in a conventional multiple needle cut pile tufting machine. A needle carrier it? adapted to be vertically reciprocated by means, not shown, support a plurality of needles, preferably arranged in a front row of cut pile needles: 11 and a back row ofloop pile needles 12. As disclosed in FIGS. 1, 2, and 3, thecut pile needles 11 are staggered with respect to theloop pile needles 12 in order to form alternating rows of cut pile and loop pile stitching. it is to be understood that the number of cutpile needles 11 does not have to equal the number ofloop pile needles 12, nor do the needles have to be alternately staggered, but the spacing and relation of the cut pile needles ll to the loop pile needles 1?; may be selective to produce the desired corresponding relationship of the rows of cut pile stitching to the rows of loop pile stitching in the base or backingfabric 13. It is also conceivable that the cut pile needles ll andloop pile needles 12 may be employed in a single row alternating with each other or in any other desired arrangement. The needles are disposed in a pair of rows in order to permit a more narrow needle gauge.
FEGS. l, 2 and 3 also disclose theloop pile needles 12 set lower than the cut pile needles Ill. in order to normally form loop pile of greater height in thebase fabric 13 than the cut pile. it is also to be understood that the needles l1 and 12 may be set at equal elevations in order to form cut pile and loop pile of equal height.
A throat plate M of conventional construction and fixed to the machine, not shown, is provided withfingers 15 which extend between the needles Ill and 12 to support thebase fabric 13 as it is fed through the machine.
Mounted below thethroat plate 14 is ahook shaft 16 and a knife shaft 37 of similar construction to those employed in a conventional cut pile tufting machine, both of the shafts being adapted for limited rotary reciprocatory motion in a. manner Well known to the art. Fixedly mounted to the hook shaft to is ahook bar 18 provided with equally spacedvertical slots 19. in a preferred form of the invention as disclosed in FIGS. 1, 2 and 3, a conventional cut pile hook 2t) and aloop pile hook 2 1 of novel construction are both inserted in eachhook bar slot 19. In the preferred arrangement, the spacing of the hook slots 1'9 are approximately equal to either the gauge of the needles ll or the gauge of needles and twice the gauge between theneedle 11 and theneedle 12.
As best disclosed in FIGS. 4 and 5, theloop pile hook 21 comprises a substantially vertical plate-like shank 22 having athroat portion 23 bent at substantially right sniaras angles to the shank along thejoint 24. Thebill 25 of the hook is preferably integral with and extends beyond the end of thethroat portion 23 and is bent down at itspoint 26. Thepoint 26 may be either arcuate (FIGS. 4 and 5) or at an angle (FIG. 6) with respect to the remaining portion of thebill 25, so long as thepoint 26 is bent sul'liciently to retain a loop ofyarn 27 formed thereon by aneedle 12;, and so long as thebent point 26 is not so pronounced as to prevent theloop 27 from being removed by theloop stripping mechanism 28.
Theloop stripping mechanism 28, disclosed in P168. 1, 2, 3, 4- and 7, comprises aloop stripping plate 29 fixed to a portion of the machine, not shown, and adapted to support a loop stripping linger 3!} for eachloop hook 21. Theloop stripping plate 29 is fixed in such a position that each loop stripping finger 3% is adapted to engage aloop 27 formed on aloop pile hook 21 as the loop pile hook is rocked backward by thehook shaft 16 from its forward position disclosed in FIG. 2 to its withdrawn position disclosed in FIG. 3, to thereby remove theloop 27 from the hook 211. As disclosed in H68. 1, 2 and 3, the loop stripping finger 35 comprises a strip of metal, such as spring steel, engaging and biased against the bottom of thethroat portion 23 orbill 25 at all times. Thus, as the loop pile hook 2i is rocked backward to its extreme withdrawn position disclosed in PEG. 3, a stationary loop stripping linger 36 engages and slides along the bottom of thebill 25 to strip theloop 27 from thepoint 26.
A modified loop stripping finger 3ll, disclosed in FIG. 5, is so constructed that theloop hook 21 is adapted to rock backward beneath thefinger 31 as the finger engages and strips theloop 27 from thepoint 26. Thefinger 31 comprises a substantially flat elongated plate having a down-turnedside flange 32, which is adapted to slide against or in close proximity to the side of thebill 25 as thehook 21 is rocked backward. Thefinger 31 may or may not engage any portion of theloop hook 21 at any time, so long as the finger engages and completely strips theloop 27 from thehook 21. Once theloop 27 is stripped from the hook 2d, the loop will be carried by thefabric 13 over the top of the loop stripping finger or 3' and theloop stripping plate 29.
heknife shaft 17 supports aknife block 33 which carries aknife 34 adapted to associate with each cut pile hook 2b to cut loops formed thereon and create cut pile in a manner Well known to the art.
Both thecut pile hooks 2% and theloop pile hooks 21 may be vertically adjustable relative to each other Within eachhook slot 19. Theloop pile hooks 21, as disclosed in the drawings, are set lower than thecut pile hooks 20 by an amount corresponding to the dilference in heights of theneedles points 26 of theloop pile books 21 are staggered with respect to the cut pile hook points in the same relation as the needles 12- are staggered with respect to theneedles 11. However, it is to be understood that the difference in height between the cut pile hooks 2a and theloop pile hooks 21 does not nece sarily have to be equal to the dilference in the height between the needles l1 and theneedles 12, so long as eachloop pile hook 21 is in a position to form aloop 27 with itscorresponding needle 12.
It is also to be understood that eachcut pile hook 20 and eachloop pile hook 21 may be inserted in separateindividual slots 19, and for this purpose, the shank 22', thebill 25 andpoint 26 of a modified form of loop pile hook. 221 may be formed in the same unbent vertical plane as substantially disclosed in PEG. 6. Fig. 6 also shows a modified form of the point 26' being bent down at an angle to thebill 25 rather than having an arcuate shape.
The means for reciprocating theneedle carrier 10, the fabric feed mechanism, and the means for driving thehook shaft 16 andknife shaft 17 have not been disclosed, as they are of conventional construction for a multiple needle cut pile tufting machine, and are synchronously driven so that the cut pile hooks 2t and the loop pile hooks 21 or 21 are rocked forward when theneedles needles knife shaft 17 rocks theknife 34 upward to simultaneously cut the loops formed by the cut pile hooks it? to form cut pile thereby. As the machine is operating, thefabric 13 is continuously fed across the throat plate 14- from the front to the rear of the machine as indicated by the arrows in FIGS. 2 and 3.
It is also contemplated that a pattern control means, such as that disclosed in the co-pending applications, Serial Number 327,807, now abandoned, and 630,343, now Patent No. 2,935,037, granted May 3, 1960, of Joseph L. Card may be associated with this invention in order to form high low loops in the loop pile stitching to form predetermined designs in the completed tufted fabric. By setting the needles 1]. and 12 and the cut pile hooks 26 and the loop pile hooks ill substantially at the elevations disclosed in FIGS. 2 and 3, and employing the pattern control means disclosed in the above applications, cut pile may be formed at a substantially uniform height, while loop pile both higher and lower than the cut pile may be simultaneously formed according to a predetermined pattern. Moreover, if the cut pile stitching alternates with the loop pile stitching, the high loops would overlay adjacent cut pile tufts, while the cut pile tufts would overlay adjacent low loops, to form contrasting designs of cut pile and loop pile in a single fabric.
It will be apparent to those skilled in the art that varions changes may be made in the invention, without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.
