Definitions

  • a device for the transfer of stitches laterally or transversely which is secure in operation A body member with a profiled part has releasably mounted therein spaced parallel stitch transfer elements.
  • the transfer elements are made of thin sheet steel of U-shaped cross-section having recesses at the sides.
  • the profiled part is provided with two spaced slotted strips to receive the transfer elements and one of suchstrips is provided with an inwardly directed nose to receive a locking strip to releasably lock the transfer elements in the body member.
  • Each transfer element has a rounded point and a concavity at the back adjacent such point to secure accurate cooperation with the needle in transferring the stitch and also the U-shaped construction allows secure cooperation with the needle to receive the stitch.
  • tickler combs are known, by means of which entire groups of stitches can be mechanically transferred laterally.
  • small tickler combs are known, by means of which a number of stitches can be manually transferred together.
  • Manual tickler combs with one to six needles are usual.
  • the needles are pulled upwards with the combs so far until the stitches are positioned behind the needle tongues in order to push the needles with the comb downward again, so that the stitches come above the tongues onto the shaft of the tickler needles.
  • the comb has to be removed from the needle hooks in order that the transfer of the stitches onto the desired needles can be facilitated.
  • tickler needles For the transfer the eyes of the tickler needles have to be hooked again into the corresponding needle hooks in order to accomplish by pulling forward said needles and overturning of the tickler combs that its stitches are brought into the hooks of said needles. All of these manipulations require long experience and besides, often tickler needles are broken oil? at their eyes, or the hooking 3,385,083 Patented May 28, 1968 of all tickler needles is not accomplished perfectly on all needles so that those stitches fall olf. It has been the dream of any knitter since the invention of the double bed machine by Lamb to find a possibility to accomplish the transfer of entire or partial rows of stitches laterally onto the neighboring needles or transversally onto the needles of the opposite needle bed. So far, most of the efforts were not successful by way of the well known tickler needles because until now nothing besides the expensive and complicated industrial mechanisms has been devised which would be rational for the home industry or for household machines.
  • the object of the present invention is to provide a novel process and device for the transfer of stitches in a lateral as well as in a transverse movement which is very secure in its function and which device can be built inexpensively in order to be utilized for home-work and household machines.
  • a further object of the invention is to accomplish the following:
  • Open-work patterns can be knitted in stocking stitch, or other cable-type patterns knitted in other stitches in an economical manner;
  • FIGURE 1 illustrates a cross-section through the mechanism
  • FIGURE 2 is a plan view of the mechanism
  • FIGURE 3 shows a transfer element in elevation, plan and section
  • FIGURE 4 is an enlarged illustration of a transfer element showing it inserted into the stitch beneath the needle head
  • FIGURES 5 to 9 illustrate details of a method in accordance with the invention.
  • FIGURE 10 illustrates a needle cam in partial plan and partial end view at the moment when the needles are being advanced.
  • FIGURES 1 and 2 illustrate a stitch transfer mechanism indicated generally at 2 having a profiled part 2 made for example of aluminium. At the underside of this profiled part there are two spaced and mutually parallel strips 2:: and 2b. In these strips, there are several parallel slots 2e (FIGURE 2) disposed perpendicularly in relation to the longitudinal .axes of the strips, into which slots stitch transfer elements 1 are inserted.
  • FIGURE 2 parallel slots 2e
  • the transfer elements 1 are constituted substantially by thin-walled U-section pieces, the forward parts of which are in the form of a rounded tip 1a.
  • the two side portions of the U-section piece each contain a recess 10 near the rear end of the transfer elements. If the elements 1 are now so inserted in the slots 2e of the component 21, that the recesses 1c come to be situated in the space between the two strips 2a and 2b, then the elements 1 can be anchored to the component 2] with the aid of locking strips 3.
  • the locking strips 3, preferably made of a springy material such as sheet steel, are so inserted between the elements 1 and a nose 2g provided on the bottom end of the strip 2b, that they locate the transfer elements 1.
  • a tongue 12 projects from above into the space bounded by the two portions 1d, this tongue very considerably simplifying the removal of the elements '1 from the components 2.
  • the strip 3 is first of all forced slightly downwards by the tip of said needle so that the left-hand edge (FIGURE 3) of the recess 10 can pass over the edge of the locking strip 3.
  • the transfer element 1 is forced out of the slot 2e of the profiled component 2.
  • the transfer elements 1 are constituted by thin sheet steel. Their tips are rounded so that they can easily be introduced into the stitches. Again, at least at the forward part near the tip, the elements 1 should be as smooth as possible.
  • the back parts of the transfer elements exhibit an inwardly-directed concavity 11; at the forward part in the neighborhood of the tip 112, the function of which will be apparent from the ensuing description.
  • the profiled component 2 also exhibits a horizontal arm 2h extending from the upper part of the strip 2a, the end of which arm has the form of a projecting lip 2d. Beneath the lip 2d a shoulder 2c is created.
  • FIGURE 4 illustrates the head or hook 11a of a needle 11 located in the channel of a needle bed 5 and situated in the incompleted castolf position.
  • a stitch 8 is suspended ready for transfer to the opposite needle bed.
  • the transfer elements 1 are fed into the stitches 8 beneath the needles 11 (FIGURE 4) as illustrated on a larger scale in FIGURE 4.
  • the needles can be placed in the incomplete cast-off position using a slide which has facility for special adjustment of the cam, or using a needle rule. In this position, the stitches are still held at their full opening by the full cross-section of the needle shank so that the transfer elements 1 can easily and surely be introduced into the stitches.
  • the concavity 1b in the transfer elements already mentioned definite centering of the transfer elements with the needles is achieved. Since the tips 1a of the elements 1 are rounded and polished, the elements 1 pass easily through the stitches and cannot hit the threads.
  • FIGURE 5 shows the mechanism inserted beneath the needles of the front bed.
  • FIGURE 6 illustrates a situation obtaining after the needles 11 have been retracted by a needle cam 12 and also shows how the stitches 8 are suspended upon the transfer elements.
  • the entire mechanism 2 is now simply tilted over the needle heads of the rear bed, as shown in FIGURE 7.
  • the portions 1d of the transfer elements 1 drop down to enclose the heads of the needles 11 at either side.
  • the profile 2 of the mechanism then rests upon the needle bed and abuts the slide rail 10 with its shoulder 20. This position is taken up at both sides of the machine independently of whether transfer is being made from the front bed to the rear or vice versa.
  • the needles 11 are then moved upwards using the cam 12, until they have passed through the stitches, this is shown in FIG- URE 8.
  • the needle cam may be made of synthetic material. It is guided directly upon the needle bed, being passed along the upper slide rail 10 for retracting the needles, and along the lower slide rail 13 for advancing them (as seen in FIGURE 10).
  • the transfer mechanism has its appropriate elements inserted beneath those needle heads in the first bed onto which the stitches are to be carried;
  • the mechanism has chiefly been described in relation to double-bed machines, but the method is also claimed in application to lateral transfer on single-bed machines.
  • a device for transferring stitches laterally or transversely comprising a body member, spaced parallel stitch transfer elements on said member, said elements being spaced at intervals corresponding to the intervals between the needles in the needle beds, said elements being made of thin sheet steel having recesses at their sides, said body member having a profiled part, two spaced slotted strips to receive said transfer elements and one of said strips having an inward pointing nose for accommodating a spring locking strip to lock said element to said body member.
  • (5696 transfer elements has a rounded point and a concavity at 3,167,939 2/1965 Imon 6696 the back adjacent said point to guide said element on the FOREIGN PATENTS back of the needle.
