Application August 1, 1936, serial No. 93,849 (Cl. 139-129) 4 Claims. 'I‘his invention relates to a needle and more particularly to a Weaving needle having an oifset pointed end adapted to easily separate’ and suc cessively pick up adjacent strands of thread or 5 yarn on opposite sides of the needle while weaving. The general aim of the invention-is to provide an improved needle by means of which weaving operations may be performed with greater facility and speed and with less attention and effort on the yarn may be located in a well-known manner. This weaving frame does not comprise a part of the present invention but is simply illustrated as a convenient support for the weaving operation, and it may be constructed in any suitable manner. 5 As herein shown, the yarn is wound about the successive pins I5 in such a manner as to provide a multiplicity of slightly spaced but substantially parallel threads'or strands I 6 extending across 10 the part of the person doing the weaving. More particularly, I provide an improved nee dle by means of which the successive threads may the frame throughout its length and correspond 10 be more conveniently and readily picked up», and danger of dropping a stitch is minimized. My improved arrangement permits of the use 15 of a longer needle, the weaving of a wider pattern, and the weaving with warp threads more tightly having a suitable strand of yarn Il passing through its eye I I, is alternately woven above and beneath the warp strands I6 to form the cross 15 strands or weft. It will be understood, of course, stretched. that the strands I6 and Il may comprise indi vidual strands, or they may comprise a single ` Other objects and advantages will be evident as the description proceeds. 20 My invention accordingly resides in the features of construction, combination of elements, and ar rangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indi cated in the appended claims. In the accompanying drawing wherein I have shown, for illustrative purposes, one embodiment which the present invention may take: Figure 1 is a sectional view through a weaving 30 frame and showing in side elevation the applica tion of my needle to a weaving operation for strands supported on the frame; Fig. 2 is a fragmentary plan view of a weaving operation and showing my needle in substantially the same position illustrated in Fig. 1; Figs. 3 to '7, inclusive, illustrate the successive steps of a weaving operation with my needle; Fig. 8 shows the application of my needle to a 40 weaving operation wherein the warp strands ini 25 tially lie in diiîerent planes; and ing with the warp strands in a weaving operation. To complete the weaving operation, the needle Ill, > I Fig. 9 is a fragmentary sectional view taken substantially along line 9-9 of Fig. 8. In accordance with my invention, I have pro ’ vided a needle I0 having the usual type `of eye II adapted to receive a suitable strand of thread or yarn and having a forward tapering end, gen erally indicated at I2. This forward end is of a somewhat stepped shape and adapted to greatly facilitate a weaving operation in such manner that it tends to prevent the dropping of stitches. My needle is shown performing a weaving oper ation in conjunction with a suitable weaving frame I4 of substantially rectangular shape and 55 supporting a series of spaced pins I5 about which continuous strand suitably wound about pins I5, as illustrated in Figs. 1, 2, 8, and 9. In Figs. 1 and 2, strands I6 are successively wound about adjacent pins to lie in substantially the same plane. Figs. 8 and 9 show a different way of winding the warp strands and wherein the end of the strands pass around pins I5 in adjacent over lapping relation to initially position the warp 25 strands in different planes. Prior types of weaving needles not only tended to drop stitches, but also had to be carefully and angularly moved during a weaving operation in order to elevate or dip the point of the needle relative to the plane of the warp strands to pick up successive warp strands. In fact, with a tight ly stretched warp, this angular movement proved so diiñcult after the needle had advanced a short distance across the pattern as to necessitate a manual manipulation of the warp strands to aid in locating them above or below the point of the needle. To overcome these various diñiculties which are inherent with prior needles, the for ward tapering end I2 of my needle is provided with a short offset pointed end portion I2’. This end portion is substantially parallel to the body portion of the needle and preferably provided with a length slightly longer than the diameter 45 of a strand of the material being woven. The end portion and body portion of the needle are interconnected by an intermediate angularly dis posed short shoulder portion I2” which is of such length as tgto oifset end portion I2’ to such an extent that during a weaving operation it will normally project above or beneath the warp strands. This shoulder portion prevents tend ency of the needle to drop stitches and also serves to cam the warp strands into their required po 55 2 ’ 2,117,350 l sitions on either side of the needle during a weav ing operation. As shown in Figs. 3 to 7 which illustrate the successive stages of my needle movement during a weaving operation with respect to three adja cent warp strands lying substantially in the same plane and herein designated as a, b, and c, the needle is ñrst fed beneath strand a and over strand b with end portion I2’ located above the 10 plane of the body portion of the needle and pro jecting above the warp strands I6 so that the shoulder portion I2” first deiiects strand by away from strand a and towards strand c, as shown in Fig. 3. As the needle is further fed forward 15 (Fig. 4), shoulder portion I2” cams strand b beneath the body portion of the needle and on the opposite side therefrom from strand a. Un like p-rior weaving operations, the extent of for ward needle movement at this time is relatively unimportant as long as the needle is fed forward sufñciently to depress strand bt beneath the body portion of the needle and on the opposite side of the needle from strand a. It will be appreciated, of course, that the weaving operation could have 25 been started in a reverse manner to accomplish the same general result by iirst passing the needle above strand a, and thereafter beneath strand b` with the pointed end I'Z' located beneath the plane of the body portion of the needle. As herein illustrated, during the initial feed ing operation of my needle, end I2' and the body portion of the needle overlie strand b. After the needle has reached this position7 it is rotated in either direction through approximately 180° so that end portion I 2’ depresses against the warp' strands and lies below the plane of the body por tion of the needle, as shown in Fig. 5. The needle is then withdrawn in a reverse direction to its normal feeding movement and to the posi tion shown in Fig. 6 wherein shoulder portion I2” ^ deñects strand b towards strand a to such an extent that end portion I2' will underlie the gen eral plane of strand c. The needle is then fed forwardly again so that shoulder portion I2” will cam strand c above the body of the needle and "Y on the oppositeV side thereof from strand b, as shown in Fig, 7. Similar to the prior forward feed of the needle, the extent of feeding move ment at this time need not be precisely limited, 51'). but must be suflicient to engage the body portion ' of the needle beneath strand c. This oscillatory and rotary feeding cycle is successively repeated until the needle has passed between all of the warp strands, after which the needle is pulled .\ , through the warp to bring the weft strand into ' proper woven relation with the warp strands. In View of the deñecting and camming action of shoulder portion I2", a wider pattern may be woven than has been found practicable with 60 prior types of needles, since it is not necessary to angularly move my needle during weaving. Fur thermore, the deñecting action of shoulder I2” facilitates weaving between warp strands which are closer together and more tightly tensioned than in prior types of weaving operations. It is not believed necessary to illustrate or describe in detail the weaving operation with my needle in respect to warp strands as posi tioned in Figs. 8 and 9 since the cycle of opera l tion is identical and the offset of end I2’ is suñi cient to position the advancing point of my needle above or beneath the warp strands, as the case may be, and shoulder I2” operates in the same manner as previously described. 75, It will thus be evident that the weaving opera tion of my needle is easily accomplished by an alternate forward and reversed feeding operation interposed by a semi-rotation of the needle, and the shoulder portion I2” will serve three dis tinct purposes; namely, separating the strands so that the pointed end I2' may lie thereabove and therebeneath, camming the strands into desired positions, and preventing the tendency of the needle to drop stitches. It will further be ap preciated that my needle has provided a con 10 venient and simple means for accomplishing the weaving operation which does not necessitate a careful scrutiny of the work by the operator dur ing a Weaving operation, since the needle may be fed any distance beyond one of the strands 15 and then turned and pulled back to drop the point beneath the next strand. It will also be appreciated that the needle may be fed through the warp strands by an inter mittent forward feed interposed by a semi-rota 20 tion of the needle to cam the strands into their successive required positions. In this method of> using my needle, it is simultaneously fedforw‘ard and rotated through approximately 180° to cause the shoulder portion I2” to flex the strands into desired positions during its rotation and cam them back onto the body portion of the needle.> It will be understood that this combined feeding and camming action is successively repeated for each strand, and it will be further understood'that in either of these methods for employing my needle, it is preferable to first rotate the needle 2.5. 319 in one direction and then in an opposite direction' to prevent snarling of the weft strand secured to the eye of the needle. This latter method of weaving is particularly useful in weaving the last few weft strands since the pattern is well ñlled at this time and the warp strands are less capable of deñeoting as the needle is moved there between. « - 40.
