2 Sheets-Sheet Original Filed Feb. 26, 1929 1 7a IZ Patented Sept. 6, 1932 PATENT OFFICE MAX 0. MILLER, 01 CUMBERLAND, RHODE ISLAND KNITTING NEEDLE Application filed February 26, 1929, Serial No. 342,858. Renewed February 4, 1932.

The invention relates to knitting needles and methods of manipulating the same and more particularly to a mending needle adapted for repairing runs in stockings or other 5 knitted. fabrics, although the invention in certain of its aspects is well adapted for use in a knitting needle used in conjunction with other needles in the knitting of new fabric.

The primary object of the present inven tion is to produce a novel and improved mending needle adapted for use in mending fine gage fabrics "which may be operated rapidly and efliciently by one having little or no experience in this work, and which requires 16 no especial skill for its successful operation.

Difliculties have been encountered in the development of mending needles, particularly when these are intended for use in the repair of fine gage fabrics, to produce a mend- 20 ing needle which can be readily and easily manipulated by the operator without long experience and considerable skill in this type of work.

In the operation of these needles as normally constructed with a swinging latch, the needle is held at an angle both to the fabric and to the wale being repaired to facilitate the manipulation of the swinging latch, as the needle is moved back and forth in the fabric, so that the tip of the open latch will pass under the strand of yarn which is to be picked up without catching additional yarns in the hook of the needle or entangling the latch in the fabric. A great deal of skill and experience are necessary before it is possible to operate one of these needles successfully to pick out a single yarn without tangling the needle hook or latch in the fabric and to cause the latch to open and close at the proper time. I

In carrying out the present invention, a mending needle has been developed which is almost entirely automatic in causing the new strand of yarn to be drawn into the needle hook and the old loop cast off, so that the operator is enabled to advance the needle through the fabric and retract it without the necessity of the delicate handling and high degree of skill ordinarily required in this work.

An important feature of the invention consists in the provision of a yarn guide which overlies the needle hook and is adapted on the advancing stroke of the needle to select or engage the next succeeding strand of yarn in the run between the guide and the needle hook and then on the retracting stroke of the needle to guide the strand into the needle hook. The yarn guide perfectly shields the hook from contact with other strands of the fabric and thus prevents any possibility of tangling the hook in the fabric on the retracting stroke of the needle.

Cooperating with these parts is a hook closing slide or member which is slidably mounted on the shank of the needle and is also shielded from contact with other strands of the fabric by the overlying yarn guide above described. With this arrangement of the parts, the operator in manipulating the needle is required merely to engage the next succeeding strand of yarn in the run between the yarn guide and the needle hook at the beginning of the fabric piercing stroke of the mending needle and then to advance and retract the needle in a substantially vertical direction through the work to take up the stitch.

Another feature of the invention therefore consists in the construction and arrangement of the needle, the hook closing slide and the yarn guide to enable the old needle loop and the new strand of yarn, by merely advancing and retracting the needle through the work, to be controlled and manipulated in such a manner that the new yarn is guided into the needle hook while the old loop is cast off.

The several features of the present invention consist also in the method of manipulating a needle in mending runs in knitted fabrics and in the devices, combinations, and

arrangement of parts hereinafter described and claimed which together with the advantages to be obtained thereby will be readily understood by one skilled in the art from the following description taken in connection with the accompanying drawings.

The preferred embodiment of the invention in a mending needle comprises a needle A, a hook closing slide B mounted to slide on. the shank of the needle, a spring C for controlling the movement of the slide, a yarn guide D which fits over the needle and hook closing slide, and a handle into which these parts are fitted indicated at E.

The hooked needle employed with the present construction comprises a substantially cylindrical shank portion indicated generally at A. which is rigidly secured at its rear end to the handle E. Towards the hook end of the needle, the shank is cut down and is provided with two parallel grooved portionsl for the hook closing slide .B, which are formed by two side walls or flanges 17 and a central dividing wall 16. At the point where the grooves 1 reach the cylindrical portion A of the needle shank, the centralwall 16 is cut away so that the slots 1 are merged into a single guiding slot 19 for the hook? closing slide B which is thus permitted to move to an open position some distance up the shank of the needle.

The hook closing member B in cross-section takes the shape of an inverted U which is adapted to run in the grooves 1 and is provided with two forwardly extending flanges 7 which serve to close the hook of the needle and are notched at 9 to engage with the loop of yarn to be cast off over the needle hook. A certain amount of frictional resistance is offered to the movement of the hook closing slide by means of the spring C which is rigidly secured at one end within the slide B by the engagement of a pin F in the slide with a corresponding grooved portion of the spring and at its free end is shaped to provide the cam surfaces 4 and 5 which ride over a pin G fixed in the grooved portion 19 of the needle shank to retard the movement of the slide B from one end of its travel to the other. The surface 5 is shaped to offer a somewhat greater resistance to the slide on its forward or hook closing stroke than is offered by the surface 4 on the return stroke. The movement of the slide B is limited at each end of its travel by stops which are indicated at 2 and 3 in the bottom; of the groove or slideway.

The hook portion of the needle A is shaped to cooperate with the hook closing slide B being provided with a thin tip 6 which extends downwardly between the flanges 12 of I the slide B to a point below the level of the notches 9 and is further provided with two laterally extending flanges 10 which are elevated sufficiently to permit the notched flanges 12 of the slide to pass under them to the hook closing position illustrated in Fig. 5. During the operation of the needle,

the surfaces 6 and 10 of the hook act to lift the loop of yarn held on the notches 9 and spread it so that it is permitted to slip off the end of the needle.

Cooperating with the needle and hook closing slide above described is a tubular shaped yarn guide D which is fitted over the needle A and slide B and is secured rigidly in position on the needle shank by a pin H. Towards the hook end of the needle, the guide D is cut away to form the tip 22 and the nibs or guiding surfaces 21 for forcing a, new strand of yarn into the'needle hook and is further cut away as indicated at 20 in Fig. 7 to permit free play of the strands of yarn between the yarn guide and theneedle shank at this point.

During the Work piercing stroke of the ,mending needle, the loop held on the needle out by the yarn guide D will be forced into the space formed as above described by the cut-away portion 20 of the guide D, the hook closing member B being forced back by the loop to its retracted position as shown in Fig. 3. On the retracting stroke of the mending needle, the new strand of yarn moves toward the tip of the needle and is directed into the needle hook by the guiding surfaces 21 of the needle guide, while the old loop is caught on the notched surfaces 9 of the hook closing slide and acts to move it forward to hook closing position against the pressure of the spring C. On the fabric piercing stroke of the mending needle, the strands of yarn are the needle shank so that the new strand of yarn which is stretched rigidly across the needle is lifted over the notches 9 of the hook closing slide 13 on the retracting stroke of the mending needle to enter the needle hook. At substantially the same point on the needle shank, the side walls 17 are cut away, as shown at 18, so that the old needle loop which conforms closely to the contour of the needle shank will be certain to engage with the notches 9 on the retracting stroke of the mending needle.

In order to operate the mending needle above described as embodying the several features of the present invention, it is desirable to stretch the fabric containing the run over a suitable frame, so that the separate strands are tightly stretched and separated to facilitate the mending operation. The needle A with its hook closing slide held in a retracted or open position by the engagement of the spring C with the pin G is placed in a substantially vertical position over the fabric and the last loop left at the end of the run indicated at 24 in Fig. 13 is caught in the needle hook. The needle is now advanced through the work in such a manner that the bar of yarn which represents the next dropped stitch, as indicated at 26 in Fig. 13, is brought between the tip of the guiding member D and the hook 28 of the needle, as indicated by the arrow at 23 in Fig. 3. As the mending needle is advanced to its foremost position, the bar of yarn 26 and the loop 2A will slide under the nibs 6 of the yarn guiding member and ride up the cam surfaces 15 to clear the notches 9 of the hook closing slide B into the open space formed between the cut-away portion 20 of the yarn guiding member D and the. corresponding surface of the needle shank as indicated in Fig. 3. Due to the taut condition of the fabric on the mending frame, the bar of yarn 26 will tend to extend horizontally across this aperture in a straight line, whereas the loop 24: will tend to conform closely to the contour of the needle shank.

The needle is now retracted or withdrawn through the fabric to cause the bar of yarn 26 to be looped about the needle hook and pulled through the old loop 24 which is cast off over the needle hook. The yarn bar 26 rides over the raised portion 16 of the central flange or wall of the needle shank to clear the yarn notches 9 of the hook closing slide B and, is then deflected by the nibs 21 of the yarn guide member D into the hook of the needle. The yarn loop 24, however, conforming to the contour of the needle shank, iscaught in the notches 9 of the hook closing member B and causes this member to move forward into the position illustrated in Fig. 5 to close the hook. The resistance offered to the movement of the hook closing member by the engagement of the spring F with the stationary by contact with the fiat portions 10 of the hook so that it is entirely freed from the notches 9 and is permitted to slide off the end of the needle hook.

The mending needle is now inserted through the fabric to recover the second stitch of the run; the bar of yarn indicated at 27 in Fig. 13 being made to pass between the tip of the yarn guiding member D and the needle hook. The hook closing slide B is retracted to the position shown in Fig. 3 during this advancing movement of the mending needle by the engagement of the yarn 26 with the end surface 14 of the hook closing slide B as it is forced out of the needle hook through the aperture 13 between the guiding surfaces 11 and 2, as indicated in Fig. 9. From this point, the operation of the mending needle to take up the next stitch of the run is as above described in taking up the previous stitch.

As previously stated, certain features of the invention are not limited to the specific construction above described, but may be applicable to mending needles and to knitting needles more generally. The mending needle herein disclosed, for instance, may be successfullv operated without the use of the guard D.

Obvious advantages both in construction and in mode of operation are secured by the use of the mending needle herein disclosed, whether the needle be intended forhand operation or whether it is operated by power. The movements required in the manipulation of the needle have been reduced to the simplest form, only a substantially vertical fabric piercing and retracting movement being required. In hand operation, the operator is required only to insert the needle in the fabric at the required point in order to insure proper working of the needle to take up the next succeeding drop stitch in the run. With the swinging latch needles usually employed, it has been necessary to insert the needle at an angle to the bars of the run in order to manipulate the latch and also to prevent the fabric from becoming entangled with the various parts of the needle, considerable skill being required to cast off the old loop and place a new strand of yarn in the needle hook, whereas in the present construction, the needle can be held in a substantially vertical position and is advanced and retracted through the fabric without the necessity of further manipulation while maintaining the needle and the fabric relatively stationary in the direction of feed to bring a new strand of yarn into the needle hook and cast off the old loop.
