KNITTING MACHINE.
Filed Dec. '16, 1936 AITOR NE Y Patented July 12,1938
UNITED STATES PATENT oer-ice Adolf Max Miller, Ghemnltz, Germany Application December 16, 1936, Serial No. 116,101 In Germany October 17, 1935 The present inventionrelates to knitting machines and to needles therefor.
In circular warp knitting machines, the needle .is generally tipped or rocked on the knocking over comb, in order, when moving up and down, alternately to diverge from or move to one side of the thread and then to catch the thread or a thread lease or crossing. The tipping and moving of the needle necessitates complicated needlebars for its operation.
According to the invention, on the contrary, the rocking out of the needle to catch the thread is effected by a device which operates between the needle and the needle-bed and presses out the needle. For this purpose, a movable intermediate'piece is provided between the needle and needle-bed, which rocks out the needle during its descent in order to catch the thread or, a thread crossing or lease, while on the upward movement of the needle the intermediate piece comes out of operation to such an extent that the needle diverges from the thread. The m'ovable intermediate piece, acting as an expanding member, can be formed by a stop. such as a lever, cam or the like, pivotally mounted on the needle or on the needle-bed, which by bearing'against a counter-stop at the beginning oi. the descent of the needle automatically rocks this latter towards the thread. At the end of the descent oi! the needle, the expanding action ceases by the counter-stop, formed for instance by a toothed rock, and the movable intermediate piece again resumes such a position that the needle in its upward movement in the non-expanded or pressed out position passes by the thread or thread crossing.
The accompanying drawing illustrates one example of construction of the invention, and show various positions of the needle in the needle-bed.
Figures 1 to 5 are sections through a needlebed, in the grooves of which the needles are moved up and down in known manner.
Figure 6 is a plan view of a portion of the needle-bed, with the needles in the highest position shortly before the needles again descend and catch the thread leases or crossings.
Figure 7 shows a single needle having a pivotally arrahged lever in the expanding position.
Figure 8 shows a single abutment in the form of a toothed rack-bar for the said lever.
The needle-bed I has grooves 2, in which the needles 3 are moved up and down. The needles are held and pressed on the needle-bed in known manner by a helical spring I. A lever I for pressing out the needle is plvotally mounted in a recess III on each needle, while on the opposing part of the needle-bed a toothed rack-bar I having locking teeth 6 and forming a counter-stop is inserted and secured by a screw 8, so'as to be capable of being changed and adjusted, 9 de- 5 notes threads or thread crossings, which are caught by the hooked end of the needle to form the knitted fabric ll.
In Figure l the needle is shownin its highest position. At the beginning 01' the descent. a stop 10 comes into operation between the point of the lever 5 and the teeth 6, so that the needle on its further descent is rocked out by the action of the lever, catches the thread 9 (Figure-2) and descends with the thread (Figure 3).
Towards the end of the descent the lever 5 comes out of engagement with its counter-stop I and passes into a sufilciently large recess I! in the needle-bed or the stop I, so that the expanding action ceases and the needle returns to its 20 normal position in the needle-bed. When now the needle moves upward from its low position (Fig. 5) the lever 5 moves in the corresponding recess III of the needle and remains depressed except for a projecting small point, so that the 25 needle on its upward movement can move to one side of the thread 9, as Figures 6 and 1 show.
- The lever or other movable stop acting on the needle as an expanding or rocking out member, may also, conversely, be arranged on the needle- 30 bed i, in which case the counter-stop, e. g., the toothed rack I will be arranged on the needle itself. The lever may also be replaced by a cam or the like.
I claim:--
1. In a knitting machine including a needlebed and a needle movable relatively to the bed, the provision of an intermediate movable member between the needle and the bed adapted to rock the needle out of its normal path on move- 40 ment of the needle in one direction and to remain inoperative in movement of the needle in the other direction. 2. In a knitting machine including a needlebeg and a needle movable relatively to the bed, 45 th provision of a stop' member pivoted to the needle on that side adjacent the bed and a counter-stop on the bed adapted for engagement by the needle to move the needle out of its normal path during movement otthe needle in one direction.
3. In a knitting machine including a needlebed and a needle movable relatively to the bed, the provision of a pivoted stop member and a counter-stop member between the needle and the 5 bed one of said members being secured to the needle and the other to .the bed said stop and counter-stop members being adapted to rock the needle out of its normal path during movement 5 of the needle in one direction.
4. In a knitting machine including a needlebed and a needle movable relatively to the bed,
the provision of a pivoted stop member and a counter-stop member between the needle and the bed, one of said members being secured to the needle and the other to the bed,- said stop and counter-stop members being adapted to rock the needle out of its normal path during movement of the needle in the downward direction.
6. In'a knitting machine including a needlebed and a needle movable relatively to the bed, the provision of a stop member pivoted to the needle on that side adjacent the bed and a counter-stop on the bed adapted for engagement by the needle to move the needle out of its normal path during movement of the needle in one direction said counter-stop member being detachable from the bed.
7. In a knitting machine including a needlebed and a needle movable relatively to the bed, the provision of a stop member pivoted to the needle on that side adjacent the. bed and a counter-stop on the bed adapted for engagement by the needle to move the needle out of its normal path during movement of the needle in one direction, said counter-stop member being adjustable relatively to the bed.
8. In a knitting machine including a needlebed and a needle movable relatively to the bed, the provision of a stop lever pivoted to the needle and a toothed rack secured to the bed, the
' stop lever being adapted to engage the rack at the commencement of the downward movement of the needle to cause angular displacement oi. the lever d to rock the needle out of its normal path, the rack being of such length that the lever moves out of disengagement therewith before the end of the downward movement of the needle to enable the needle to move back into its normal path.
9.--In -aknitting machine including a needlebed and a needle movable therein, the provision of a stop lever pivoted to the needle and adapted to be substantially housed in a recess in the needle and a toothed rack on the bed, the stop lever, during upward movement of the needle, being adapted to remain in said recess to enable the needle to move in its normal path and to pass to one side of the thread but, at the commencement of the downward movement of the needle, to engage said rack bar to rock the needle out of its normal path to enable the needle to engage the thread.
10. In a knitting machine including a needlebed and a plurality of needles movable relatively to said bed, the provision of a toothed rack bar in the needle-bed adjacent the path of the needles, and means in connection with said needles and adapted to cooperate with said rack to divert said needles from their normal path.
11. In a knitting machine including a needlebed and a needle m'ovable relatively to said bed, said needle having a recess in one of its longitudinal surfaces and spaced from both ends thereof, a stop lever pivoted to said needle and movable into said recess, and means in connection with said bed and adapted to cooperate with said lever to divert said needle from its normal path.
