13 Claims. (01. 66-117) There are actually two different kinds of 're-- looping needles, viz, the so-called latch and slider needles. With both these needles it is necessary to use a certain amount of force to move the latch or the slider, and this force has to be supplied by the. loops. The highest mechanical effort exerted on the'loops'occurs when use is made of nee-- dles with sliders and this mechanical effort can 5: be considerably reduced when use is made of needles with latches. Yet even in this case there is with certain needles the ,force, small as it may be, of a spring to be overcome. ther, attention must be drawn, in particular 511 with regard tothe superior needles with latches to the fact that the to and executed completely, or else it may easily hap' pen, that the loop sliding up along the needle does notreach the tip .of the latch and again slides down the latter; the work must then be interrupted or the needle slips out of the fabric. The subject-matter of the invention is a needle,

with which all these inconveniences are eliminated, and this due to the fact that it has, in a longitudinal groove inthe shank of the needle and near the hook ending said shank, a member lying free and-rolling between two end positions, which when touched tangentially by the loops sliding along the shank is taken along in Q rolling movement and in one of its end positions closes the hook opening and brings the loop taking it along over said hook, and in the other end position on the contrary lies at a short distanee from the bent back part of the hook.

I} As however the loop slidingupwards along the shaft out of .the inside of the hook should, when the needle isforced possible overits path without friction and impediment, it has further been'provided that the i so constructed rolling member orv small wheel can when rolling back disappear into a cavity in the groove of the needle. Then in order to be able during the following workingmovement to draw the small wheel out of this position, the front part of the shank is, finally, at corresponding points provided with a notch to enable the downsliding loop to reach from behind the cir-v cumference of the roller and thus to raise said roller out of the cavity and bring it into the rolling position.

Practice has however shown that the operation in questionjdoes not always takeplace readily and particularly that the small wheel does not always-roll out of the cavity as desired, but is more often simply displaced. The consequence Fury no movement isforward, .travel as far as is an increase in the effort exerted on the loop in question.

By increasing the diameter of the rolling member and widening the cavity, so that the small wheel lying therein projects from behind over the rear part of the shank, the back loop already raised and sliding along the rear part of the shank simultaneously with the front loop can be made to reach the small wheel and raise it out of the cavity. When the needle withdraws from 0 the working 'fabric, the'small wheel is then so to speak delivered by the back loop to the front loop, since it is known that with regard to the movingdire'ction of the needle the back raised loop precedes the front loop to be raised.

If, however, as just pointed out, a small wheel of greater diameter is chosen, this means nothing else but another wider part of the needle exerting on the loops a greater mechanical elTort and this is tobe avoided.

In order to eliminate the inconveniences just mentioned, a further object is to provide a needle having a small wheel with a slider capable of a limited swinging and sliding movement in a front groove in the shank; this slider has aside from a rear rest-point for engaging the small wheel adjacent its axle, the feature of utilizing the axle of the wheel as the front rest-point, while profiled parts provided onthe front and back side of the slider serve to transmit the impulsions received from' the loops to the small wheel, so that the latter is readily raised from a cavity and made to roll. 3

It has alreadybeen proposed to use in the shank sliding sliders as well as rectilinear guided sliders and also sliders that are capable of moving and swinging simultaneously. The former sliders mentioned have however the disadvantage that they render more difficult the. penetration of the needle into the fabric. In particular because it is necessary to provide these sliders with an under projection which widens the profile of the needle and causes a useless and even dangerous stretching of the loops. This'was the reason why the slider was then made slidable and capable of swinging, in order that during the penetration of the needle the preceding loop picked up could raise each time the slider provided with the back projection; the slider was then sunk again by the following loop to be raised entering into contact with its upper edge so that a smoother sliding through was the result. When, however, the needles constructed in this way draw back, the'slider is so to speak jammed between the two above named loops and brought along into the closing position against the action of a spring. This jamming however causes once more a useless and defective mechanical effort of the loops, in particular because the action of a spring is to be overcome, which only discharges the loops when the needle is forced forward, and stretches them all the more in the other direction. This spring cannot in this known execution be dispensed with, since it prevents the slider from sliding under the action of its own weight and ensures moreover a sliding back movement of the slider in the rear rest position, which would not otherwise be effected in a regular manner.

The accompanying drawings show by way of example a relooping needle according to the invention with its small wheel and an improved needle of this kind having a small wheel and a slider. The working and the advantages of these needles will be made clear by the following explanations, accompanying said drawings.

Fig. l is a side view and Fig. 3 a plan view of the needle according to the first embodiment with a wheel; Fig. 2 shows the hook in side view; Fig. 4 shows said hook in a slight variant; Figs. 5, '7 and 8 show side views of a needle according to the second embodiment, with a wheel and a slider, on a larger scale and in the close position, in an intermediate position and in the lowest position of the small'wheeh Fig. 6 is a corresponding plan view of Fig. 5; Figs. 9 to 17 show in perspective a view of the whole working when a loop is raised, and are all seen from above, so that the upper side of the fabric is visible, with the exception of Fig. 14, which corresponds to a view seen from underneath; Figs. 18 to 21 relate to some variants which can be made in the needle according to the invention and these are shown on a greater scale compared to that of Figs. 5 to 8.

The needle according to Figs. 1 to 4 consists of a body I with a hook 2. In the shank is provided a longitudinal groove 3, which by means of a narrow part at l is divided into two parts, of which the second and foremosfljils designated by the numeral 3'. In said groove a lies a small wheel 5 constructed in the form of a grooved wheel, which can roll to and fro between two end positions in the groove. Fig; 1 shows the hindmost end position, which is limited by the abutments is forming the narrow part l. Fig. 2 shows the foremost end position which is limited by the end I of a wire 8 which is bent round in the form of a hook.

Said wire has its rear end 3 jammed in the shank of the needle, and this at a certain distance from the hook 2, near the rear end of the shank. Further on, it lies free in the groove 3, then in the groove of the wheel 5. The latter is effected with a certain play, so that no friction can in any way arise between wheel and wire and the latter, besides limiting the forward rolling movement, further serves to prevent the wheel from falling out.

The working of this needle is easy to see from Figs. 1 and 2.

A loop sliding up over the hook 2 and along the shank arrives tangentially over the wheel 5 and takes same along with it without friction and in rolling movement, to the position according to Fig. 1.

If the loop slides down again, the wheel is likewise taken along without friction and in rolling movement, to the position according to Fig. 2. In said position however the entry into the hook 2 is closed and the loop, led by the circumference of the wheel, sides over the hook 2.

For this operation the upper surface of the shank lying on the side of the loop can be made rectilinear or for instance as shown in the drawings, have a notch 9, owing to which the loop arrives a little lower down behind the wheel, which itself lies in the corresponding end position in a hollow ll] .in the groove 3, into which it constantly rolls.

"Fne needle, as well as the wheel are preferably made of material capable of being magnetized and are magnetized, so that the wheel 5 remains in the end position, being subjected to no friction or hindrance except a very small magnetic force.

With the variant according to Fig. 4 the difference lies in the fact that the foremost end position of the wheel 5 is determined by the inner abutment H, while the end of the wire 8 is straight.

Of course the wire 8 can shorter, yet it is preferable to provide its point of fixation 8 as far from the wheel 5 as possible so that should any eventual contact between the wire and the wheel occur in the course of the rolling movement, the braking and elastic action of the wire remains as small as possible.

The needle according to the second embodiment shown in particular in Figs. 5 to 8 consists likewise of a body I with a hook 2 and comprises like the needle just described a small wheel 5 which can roll to and fro in the wider front part 3' of a groove 3 the back part of which is narrower. At 3" the broader part of said groove penetrates into the shank of the needle, so that the small wheel can reach a, lower position corresponding to Fig. 8, in which the groove-opening, the length of which is somewhat smaller than the diameter of the wheel holds back the small wheel, i. e., prevents it from falling through.

In the narrow part of the groove 3 as well as in the notch of the small wheel extends a slider H. which has two rest points one in front on the of the small wheel and the other at the back inside the groove 3.

Near this rear part the slider has a notch M which in cooperation with a pin i5 of the shank limits the liberty of movement lengthwise. Immediately behind the small wheel the slider has an under projection it which in the lowest position of the small wheel (see Fig. 8) behind the shank projects over the lowest position of the small wheel. To let through this projection the narrower part of the groove 3 in front between the positions 3 is led through the shank of the needle.

The connection with the small wheel is effected in that the corresponding end of the slider is constructed in the shape of a fork and received therein the axle of the small wheel. Further the upper edge of the slider has immediately behind the small wheel an incipent notch I! behind which a raised part l8 of the upper edge leads to the notch l4.

Attention is drawn to the middle position, according to Fig. '7, occurring between both end positions of Figs. 4 and 8 during the forward movement of the needle, in which position the best practical measurements of every part of the needle can be determined. In this position, in which the axle of the small wheel lies on the middle line AA of the shank of the needle, the small wheel whose diameter is slightly greater be made considerably than the width of the shank containing it, ex-

the small wheel is however tangential to a line B -B, which extends the direction of the rising part from the inside of the hook to the upper edge'of the shank, while the slider strikes backwards against the pin l5.

It is to be remarked that the length of the slider to the pin is immaterial, so that the notch I 4 and the correspondingly situated pin 15 may be if desired far removed from the small wheel.

The measurements of the projection 16 are chosen according to the following points of view: it must approximately, as shown in Fig."20,"ex, ceed the circumference of the wheel by a height H which corresponds to the height or thickness of the Wall of the shank of the needle inside the groove. This, in order that the small wheelcan be raised by a loop travelling behind the shank of the needle up to the inner fiat part of the part of the groove in question, in order tobe able to roll there without difliculty.

Then the outer or upper-edge-part ll of the slider (see Fig. 8) must however, also run, at least approximately, parallel to. the under edge iii of the projection l6.

Further the lowest part of the notch H as is easily gathered from Fig. 5 must, with regard to the highest part of the projection l6 be located behind. Y

Finally the raised part l8 of the upper edge of the slider must in the inmost position of the latter (according to Fig. 8) project still a little over the upper edge of the shank.

In Figs. 9 to 17 the loop about to be raised in a working operation has been represented in black so that this operation may be better understood. Said loop, which has been designated as the front loop has the reference numeral 1 9 while the so called back loopjust raised is designated by the numeral 20. The appellations front and back loop are justified in that in the working operation to be described the first loop slides along in front and the second behind the shank.

In the issuing position according to Fig. 9 the slider and small wheel can, as shown, eitherbe in the close position, which is the case, when the operator is in the middle of the work, or they can also be in the open position according to Fig. 8, when the operator is just beginning to work. The loops lie in both cases, as shown in Fig. 5 at 69 and 20. I

The needle is now from the position shown, driven in the direction of the arrow 2! into the fabric and soon reaches the position according to Fig. 10, in Which the front loop 19 is about to come against the small wheel 5 and to move the latterbehind in arolling movement. Owing to its slight tension, this front loop l9 during the movement of the needle hastens after the loop 20 as this can be inferred-from the positions of these loops shown at Ma and 20a in Fig. 5.

When the needle is advanced, these loops ar-.

rive in the position according to Fig. 11, in which the loop l9 now over the small wheel, accelerates,

owing to the frictionless rolling of the latter, its

movement with regard to the needle, so that it suddenly reaches the position designated by the'numeral llib in Fig. '7, in which it neither precedes nor hastens after the loop 201). Si multaneously with the rolling of the small wheel "is slider it was brought into its back end position to strike against the pin l5. It is stillonly possible both for the end of the slider and the small wheel to swing round the pin I5 as centre.

The rolling movement of the small wheel which has just taken place fromthe previous close position in the last position described is actually the first movement which occurs, taking place over a very short distance along the groove 3' in the direction of the axis of the shank, until the small wheel comes over the opening 3" and there becomes free, to move across the direction of the shank. The small wheel however remains prevViously in its middle position, because the small wheel and slider as will be seen from the positions I 9b, 2% of the loops in Fig. 7, arebrought between the latter. during this operation the loops are practically in no way subjected by any wider parts to an eifort greater than the penetration of the smooth shank of the needle requires.

When the needle is driven further into the position according to Fig. 12, the loop it reaches the notch I I of the slider, which is simultaneously It is to be remarked thatv raised a little out of the shankby the loop 263 meeting the projection l6. Said operation can be understood with the help of Fig. 7, that,

the loop 20?), which now slides up the back part, of the shank I, forces the projection it into the shank, while the loop illb, which slides up the front part of the shank, moves along the part ll into the lowest part of the notch ll. The two loops are in no Wise however drawn away from each other or stretched in. an inadmissible way because the edge it" runs ape proximately parallel tothe edge it? '(see Fig. 8). The needle thus forces through the fabric, as if the shank were runningsmoothly over its whole length. I

Nor do any of the loops, when the needle is pushed further into the end position according to Fig. 13, meet with any considerable resistance.

The loop 20, which now lies behind the projection I6 has below it toward the lower end of the needle the smooth back part of the shank of said needle' The front loop 19 on the contrary comes against the raised upper edge It of the slider, which though constantly swinging round the pin it is sunk into the shank and the small wheel 5 is pushed under to its end position into the opening 3". This movement takes place without any friction or application of force and finally -the two loops are found inthe positions the and 200 of Fig. 8, and this again with the loop 590 lagging behind.

As will be seen in the last named Fig. 8, the slider is so constructed that in said lowest position it projects slightly though very little over the frontedge of the shank, so that the loop it presses it securely down and there holds it rather Of course the needle can be pushed into the same will of necessity be limited.

The arrow 22 in Fig. 13 shows that the needle is now drawn back. During this drawing back operation the loops l9 and 29 slide down along the shank, yet while'the loop I9 is first being taken along so that it again. with regard to the new sliding direction, hastens after the loop 29, until the positions [9d, 2001 represented'in S are reached, which correspond to the view from underneath of Fig. 14. Here the loop 2% is situated close behind the projection it of the slider I2, which through the further advance of this loop is raised and pressed forward, so the small wheel has .difficulty to turn roundthe edge K of the opening 3" in the direction of the arrow 23. This rotation is partly executed,

but the small wheel is also partly raised from the edge K and raised up into a position, ap-

proximately as shown in Fig. '7, though moved a little more forward. This depends on the inclination of the needle with regard to the fabric, on the actual position of the downward sliding loop l5 and on the profile of the part it of the front edge of the slider which has come against the last named loop, whereby the swinging and moving action of the slider and small wheel is influenced.

At a given moment, when the loop 20 is sliding over the side of the projection iii, the loop i9 arrives in the lowest part of the notch H which with regard to the point of the hook lies behind the side of the projection 16. This again corresponds to the movement of the loop 59 hastening after the loop 28.

The slider has, as already said, swung, also moved a little forward. Both loops however go past the slider, without being in any way pulled apart by a sudden widening of the needle or subjocted to too great a mechanical effort.

When the needle is further drawn back according to Fig. 15 the loop l9 slides over the front of the sloping outer edge portion ll of the notch l1, and the immaterial resistance here occurring contributes to move the small wheel. a little further forward, into a position, where then under the influence of the loop brought and rising upon same is moved according to Fig. 16 readily into the rolling. Simultaneously, however, the hook 2 has seized another loop.

From the position according to Fig. 16 the small wheel rolls frictionless to the end'position and brings the loop over the hook which is closed by this small wheel, as shown in Fig. 17. Moreover the exit position shown in Fig. 9 is reached, with the loop 20 occupying the former position of the loop l9 and the loop l9 occupying the previous position of the loop 23.

On the next to and fro movement of the needle the operations just described are repeated.

From what has already been said it follows that the different members of the needle have the advantage of certain particular relations which were mentioned at the beginning of this description and which can be recapitulated as follows:

The raising of the outer edge portion H lies substantially parallel to the edge I6 of the projection [6.

This projection exceeds the circumference of the small wheel by a height H, which corresponds to the thickness H of the wall of the shank of the needle inside the groove.

The lowest part of the notch l'i lies with regard to the point of the hook further back than the side of the projection Hi.

In the lowest position of the slider, the upper edge of same projects slightly over the front end of the shank.

Finally the operations already described with the help of Fig. '7 are complied with in an excellent manner.

The inner back edge 2d of the slider need have no particular form, but merely the possibility of swinging round the pin l5 and the sliding of the slider must be ensured a little play.

The back-edge-part 24' is made concave, especially in order that the slider may be lighter and this result is also obtained by the fact that the slider is bored at different points to provide perforations.

The needle according to the last described embodiment has, like other needles with sliders, the advantage that it can in no manner slip out in the course of the work, as is often the case with needles provided with latches. If, for instance, with the needles provided with latches the stroke of the to and fro movement is unintentionally shortened, it may happen that the needle is drawn back with the slider half-open; then the slider slides into a front loop to be raised next and brings the latter with the loop sliding along the shank over the hook, which then contains no more loops and slips out. This ac cident cannot occur with the needle according to the invention.

With the known slider-needles provided with a back-drawing spring it may however happen, in particular, if the fabric is not tightly stretched, that the loop sliding along in front of the shank makes it impossible to bring the slider forward against the action of the spring and against the friction arising from the pressure of the loop along the bottom surface of the needle-groove. In this case the loop slips off the slider and arrives in the hook with the loop that has already been taken up. The hook, then, contains two loops, for instance the loops l9 and 23 of Fig. 16. On the next to and fro movement of the needle, the matter can of course be put right once again, the needle however stops once or several times in succession, and this leads to an irregular execution of the work undertaken. This is impossible with the needle according to the invention. In the latter there is neither an increase in friction nor the action of a spring to be overcome, so that slider and small wheel are taken along regularly and readily to the close position.

Another advantage to be remarked is the fact that the path travelled over by the working needle in its to and fro movement, that is to say the stroke of the needle, can be maintained considerably shorter with the needle just described than with the usual needles with sliders. With the .latter the slider cannot on the one hand be made considerably wider than the width of the shank and on the other hand the slider must when pushed forward, give with the front edge of the hook a smooth surface. The hook of the needle cannot thus be considerably wider than the shank of the needle, but must for this reason be rather far removed longitudinally therefrom, i. e., there must be a rather great hook-opening to prevent the loop sliding along the shank in front of the slider from slipping off the hook. This lengthens the needle unnecessarily and consequently the stroke necessary in the working.

With the needle according to the invention the hook-opening can be considerably diminished longitudinally, because the hook of the needle can be made a little wider than the needle. owing to the slight lift which the loop brought over the hook receives from the small wheel. The shortening of the stroke of the needle saves time in working and diminishes the friction on the loops.

Practice has further proved, that the needle according to the second embodiment described can never slip out, even when several rows of loops lying side by side have to be picked up. The needle readily picks up both the series lying with regard to the direction of working to the left and to the right, and this has hitherto never been attained. This is peculiarly advantageous when owing to a hole in the fabric several rows of loops have sprung up on either side of said hole, forthen for instance on one side of the hole a row lying on the right can be picked up and then on the other side of the hole a row lying on the left, which row is immediately tied with the first named row, and so forth, whereas hitherto the process was to pick up all the rows lying side by side on one side of the hole and to hold them fast with a thread, till all the rows lying side by side on the other side were likewise and similarly picked up.

Fig. 18 shows on a larger scale a variant of thefront end of the slider, which is intended, through-the arrangement of a front edge-part 25 rising and projecting over the small wheel, to facilitate or at least to bring the rising movement of the loop sliding up from the hook on to the small wheel, while the small wheel is rolling back a little earlier than in the case already described. The arrangement must of course be such that the nose formed by'this bevel on the end of the slider projects over the back 23 of the needle nowhere in the hindmost and lowest position shown in dot and dash line.

Fig. 19 shows, how asmall spring 27 can be fixed behind in the groove 3 of the shank of the needle, for instance-by pressing its back part 28 drawn'in black, between the'side walls of the shank, with the object of jamming very slightly the slider l2 in its rear rest position and thus to ensure the corresponding open position of the needle, so that the latter is constantly ready for work. If such a spring is absent, the needle can be opened very easily, while it is being driven into the fabric in the usual manner. It opens readily and on the following drawing back movement executes its work correctly.

Figs. 20 and 21 show, how by altering the inclination of the back edge of the projection IS the needle can be constructed so as'to close early or late. In the embodiment according to Fig. 20 this rear edge It lies almost perpendicular to the direction of the shank, so that slider and small wheel arevery quicklyraised by a'loop arriving in the direction of the arrow 29 against said edge. In the embodiment according to Fig. 21, the edge i6" is on the contrary very much inclined, so that a loop sliding along the back part of the shank-part in the direction of the arrow 38 will produce a slow rising of slider and small wheel. I

By means of a suitable inclination of the edge IE or 16" theworking speed of the needle can especially be influenced. Thus the needle must correspondingly be more or less inclined according to the fabric treated. The more or lesser grossness or fineness of the fabric can finally influence the working, so that in the event of different fabrics having to be treated, needles can be made having projections of different shapes.
