No. 344,081
Claims priority, applicatignsggarmany, Feb. 15, 1963,
2 Claims. (a. 66-75) This invention relates to knitting machines, and particularly to a needle selection mechanism for producing patterned knitted fabrics on a knitting machine.
It is known to produce patterns in knitted fabrics by lifting only selected needles to a clearing position, while lifting others to a tuck position, and leaving others in the rest position. The needle selection of the known machines relies on Jacquard card mechanisms and similar relatively complex devices. The preparation of Jacquard cards is relatively costly, and other known mechanisms similarly require a relatively large amount of costly labor to prepare a knitting machine for knitting a specific pattern.
An object of the invention is a needle selection mechanism which can be set for any specific pattern in a simpler manner than was heretofore available.
Another object is a needle selection mechanism which occupies but a minimum of space.
The invention relies on an electromagnetically actuated selector mechanism which controls movement of each needle from the rest position to the tuck position or the clearing position. It is known to actuate electrornagnets in timed sequence by means of moving punched tapes which cooperate with microswitches, or which transmit light pulses in timed sequence. The light pulses are converted to electrical signals by photoelectric cells, and the signals energize relays in circuit with the electromagnets. Obviously, program carriers other than punched tape may be employed in cooperation with photoelectric cells, such as moving film strips having areas of different density. Magnetic recording tape cooperating with reading heads in a conventional manner also is a suitable program carrier,
and others will readily suggest themselves to those skilled in the art. :It will be understood that the transport mechanisms for the punched tape, the film strip, or the magnetic recording tape must be driven by the main drive of the knitting machine or be otherwise synchronized therewith.
The exact nature of this invention as well as other objects and advantages thereof will be readily apparent from consideration of the following specification relating to the annexed drawing in which:
I FIG. 1 shows portions of a flat bed knitting machine equipped with a needle selector mechanism of the invention, the view being in side-elevational section on the longitudinal axis of a needle and perpendicularly to the needle bed;
FIG. 2 shows a part of the cam arrangement of the machine of FIG. 1 in the plan view;
FIG. 3 shows the cam arrangements of FIG. 2 in front elevation, and partly in section;
FIG. 4 is a fragmentary view of the device of FIG. 1
in a different operating position; and
FIG. 5 is a view corresponding to that of FIG. 4, but illustrating yet another operating position of the device of FIG. 1.
Referring now to the drawing in detail, and initially to FIG. 1, there is shown only as much of a flat bed knitting machine as is necessary for an understanding of the needle selector mechanism with which this invention is more directly concerned.
A latch needle 1 is longitudinally slidable in a groove of a needle bed 14*which supports a plurality of needles as is conventional. The needle has a long lifting butt In at the end of its stem remote from the latch. A jack 2 abuts against the needle 1. A finger 3 is pivotally attached to the end of the jack 2 remote from the needle 1 by a hinge 3a. The finger 3 carries a short pattern butt 4. While only a single needle 1 and the associated jack 2 and finger 3 have been illustrated in the drawing, it will be understood that the knitting machine has a multiplicity of needles arranged in the bed 14 in the manner shown.
The butts 1a and 4 cooperate with two longitudinally spaced sets of cams arranged on a common support 40.
The cams travel with the support 40 transversely of the direction of elongation of the needles 1 during operation of the knitting machine as is conventional. The cam set 41 is longitudinally aligned with the short butt 4 when the needle 1, jack 2, and finger 3 are in the rest position illustrated in FIG. 1. The set 42 is longitudinally offset from the long butt 1a in the illustrated position.
The cam set 41 constitutes the pattern cam of the knitting machine. It includes a hump 43 whose face 5 slopes from the cam support 40 toward the needle bed 14 in the direction of relative movement of the camsupport and needle bed. It drops abruptly from a flat top to the surface of the support 40. A hump 44 aligned with the hump 43 in the direction of relative movement of the support 40 and of the needle bed 14 has two parallel sloping faces 6, 17 which are perpendicular to the support 40 and obliquely inclined to the direction of elongation of the needles 1. The cam face 17 is adjacent the support 40 and nearer the hump 43 than the 'cam face 6 which is spaced from the support 40 toward the needle bed 14.
The second cam set 42 includes the knitting cams of the machine. A tucking cam 12, a clearing cam 13, and a guard and stitch cam 13a are separated from each other by gaps adapted to receive the long butt 1a. The clearing cam 13 is longitudinally aligned with the cam face 17, and the gap between the tucking cam 12 and the clearing cam 13 is aligned with the cam face 6.
A lever rotatably mounted on a stationary pin 9 is associated with each needle 1. One arm 7 of the lever is urged against the finger 3 by a helical tension spring 16 attached to the other lever arm 8. The spring 16 holds the butt 4 in engagement with the pattern cam set.
A solenoid 15 having two axially spaced windings is adapted to cooperate with the lever 7, 8, The armature rod15a of the solenoid carries a latch 10. An edge of the latch 10 has a notch 11. In the normal condition of the solenoid 15, the latch 10 is out of range of the lever arm 8. When the solenoid is energized, the latch is moved toward the lever arm 8 until the notch 11 can receive the arm, as shown in FIG. 4, or until a stop 15b of the armature abuts against the solenoid as shown in FIG. 5.
The aforedescri'bed apparatus operates as follows:
With the latch 10 in its normal position, as shownv in FIG. 1, the short butt 4 travels over the hump 5 under the pressure of the spring 16 and sequentially assumes the positions thereof illustrated in FIGS. 1, 4, 5, and 1. It is then engaged by the cam face 17 of the hump 44 and travels longitudinally in the needle bed 14. The finger 3 pushes the jack 2 and the needle 1 toward the right, as viewed in FIG. 1, and the long butt 1a enters the gap between the clearing cam 13 and the stitch cam 13a. The needle is shifted to its clearing position and performs a normal knitting cycle.
When one of the windings of the associated solenoid 15 is energized while the butt 4 travels over the flat top of the hump 43, the latch 10 is pushed toward the lever arm 8 into the intermediate operative position illustrated in FIG. 4. When the butt 4 drops from the end of the hump 43, the arm 8 engages the notch 11 on the latch 10. The butt 4 is held far enough from the cam support 40 to clear the cam face 17, but is engaged by the cam face 6.
The resulting longitudinal displacement of the jack 2 and of the needle 1 shifts the long butt 1a into the gap between the tucking cam 12 and the clearing cam 13. The needle 1 is only shifted to its tuck position.
When the second winding of the'solenoid 15 is energized while the short butt travels over the flat top of the hump 43, the lever arm 8 engages the side of the latch 10 when the butt 4 reaches the end of the hump 43. The butt 1a is held in an inoperative position in which the butt 1a clears the knitting cams during relative movement of the cam support 40 and of the needle bed 14. The needle 1 is not moved from the illustrated position.
Instead of a solenoid with double windings, a solenoid having a single winding may be employed, and the stroke of the armature rod a may be controlled by abutment of the latch 10 against the arm 8. Movement of the armature takes place at the precisely timed moment at which the edge portion of the arm is aligned with the notch 11. With a solenoid having only a single winding, I prefer to omit the notch 11 from the latch 10, and to provide the arm 8 with one or more notches analogous to the notch 11, so that the end face of the arm 8 is stepped. The distance traveled by the needle 1 is then determined by the step of the arm 8 engaged by the latch 10.
In the invention described hereinabove with reference to the drawing, the pattern mechanism depends mainly on an electromagnetic control device for limiting the longitudinal movement of a knitting needle. The well-known simple and reliable devices for controlling the flow of electric current to an electromagnet are available for energizing and deenergizing the electromagnetic control devices of the invention in timed sequence with the other movements of the knitting machine.
It should be understood, of course, that the foregoing disclosure relates only to preferred embodiments of the invention, and that it is intended to cover all changes and modifications of the example of the invention herein chosen for the purpose of the disclosure which do not constitute departures from the spirit and scope of the invention set forth in the "appended claims.
