In this manner, the size of the newly formed loops can be influenced. It is also possible to turn sleeve 10 within hub portion 33 a few degrees in order to regulate the coulier motions of the dial needles which is accomplished by a worm gear transmission, not shown, in a known manner, and since such a transmission is selflocking, no turning movement of sleeve 10 in hub portion 33 is possible during normal operations.
- Cylinder support ring 7 has a cylindrical outer portion 7a to which a ring 9 is secured. Ring 9 extends around the entire periphery of the machine and has an annular This recess is used for Bowden cables by which certain patterning operations are controlled, and also for electric wires for drive motors at the several knitting stations of the machine. This construction has no bearing on the present invention. Above recess 43, an annular duct 44 is provided in accordance with the present invention and communicates through a plurality of circumferentially spaced openings 45 with the chamber II which surrounds cylinder cam box 5, needle cylinder 1, dial 2, and dial cam box 6.
- a tube 44a is connected to duct 44 and to an exhaust fan means, not shown, for drawing air out of duct 44 and consequently through openings 45 in direction of the arrows s out of chamber II.
- Ring 9 has a rim portion 9a projecting above cylinder-support ring 7 and being formed with openings 45, and with a pair of adjacent circular grooves 9b confronting a corresponding pair of circular grooves 38b in rim portion 38 of dial support means 11.
- Transparent wall sections 42 are mounted for sliding movement in grooves 912 and 38b and can be placed in a position in which they form a substantially circular transparent wall surrounding chamber 2 and closing the same. When some of the transparent wall sections 42 are shifted in the grooves, an opening is formed between rims 38 and 9a, permitting access to the cam boxes and to the needle carrying rotating elements 1 and 2.
- the spaces between the radial ribs 39 are also closed by transparent walls or panels 40 which have openings with eyelets 41 through which threads are guided at the several knitting stations into chambers II and to needles 3 and 4. Otherwise, the transparent panels 4 completely close chamber II, although they may be detached if access to the chamber is desired.
- a completely closed housing with an annular chamber II is formed around the cam boxes and the needle carrying portions of the needle carrier means 1 and 2 preventing any extraneous dust from falling onto the needles or other moving parts of the machine.
- dust developed during the knitting operations can be carried through the annular gap between the dial and the needle cylinder by air entering through tube 49, annular duct 47 and openings 48 into the inner space IV. The dust is then exhausted through openings 45.
- Thread guide housing 15 is mounted on top of dial support means 34.
- Thread guide housing 15 has a bottom wall 54 and a circular curved side wall terminating in a peripheral flange portion formed with a circular recess 30.
- Thread guides 19 project in the region of the knitting stations from the flange of housing 15.
- Housing 15 has a circular bottom face 72 resting on a corresponding circular top face 31 of annular portion 34a.
- An annular duct 35 is formed in portion 34a and communicates through openings 36 with chamber II. Part of duct 35 is formed by a recess 32 in the bottom face of housing 15 and openings are provided into which air hoses 37a, 37c, 37d are inserted.
- Circular walls 54 and 34 form another chamber III in which gear 53 and hub 53a are located.
- Cap wall means 23 and 24 form a housing portion 16 for supporting thread transporting means 17 and thread spindles 18.
- the thread transporting means 17 are provided at each knitting station, and are preferably smooth cylindrical rollers driven by electric motors disposed within the hollow rollers.
- 'Electrical cables for supplying the motors are preferably located in the annular recess 30 which is closed :by the annular bottom surface 29 of wall 2-4 which rests on two annular top faces '25 of the flange of housing 15. Electrical cables may also lead to the motors within a chamber 1 formed between the capshaped housing 16 and the thread guide housing 15.
- the thread passes from spindles 18 to thread guides provided in a position above the cap wall 23 and from the same downwardly to the respective thread transporting rollers 1 7 which supply the thread through thread guides 19 and 41 to the knitting needles in chamber II.
- the higher thread guides are mounted on arms of a rod 21 secured to the center of the top wall 23. The details of the arrangement are not an object of the invention and therefore not illustrated.
- blower means 28 are mounted in the closed chamber I formed by circular walls 23, 54 and annular walls 24 and a. Tangential blower means, such as a cross flow fan, are preferred.
- the blower means have a housing with an inlet 28a communicating with an opening 26 in wall 23 which is closed by screen and air filter 2 7.
- the outlet 28d of blower 28 is connected to hoses 37a, 37c, 37d by which air is blown into annular duct 35 to pass through circumferentially spaced openings 36 in direction of arrows B into chamber II.
- annular recess 55 is provided in which circumferentially spaced lamps 56 are mounted. Lamps 56 illuminate chamber II and the knitting area to facilitate inspection of the same through the transparent walls 40 and 42.
- a particularly advantageous elfect of lamps 56 is illumination of transparent wall sections 42 from the inside whereby reflections of the outer surface of a transparent wall section 42 are eliminated which would develop if only extraneous light would be used for illuminating chamber II.
- wall means 34, 33, 6, 5, 7, 42 and 40 form a closed annular chamber around the knitting area. Nevertheless, the knitting operations can be observed through the transparent wall sections 42 or 40.
- Dust blown out of the annular gap between the dial and the needle cylinder into annular chamber II may settle in this chamber, and in order to prevent such occurrence, air is blown by blower 28 onto the annular duct 35 and passes through openings 36 into chamber H where it stirs up the dust and develops air tubulence in which dust is suspended.
- the exhaust fan means not shown, connected to tube 44a draw the air and the dust out of chamber II through openings 45 and annular duct 44. In this manner, the working area is completely free of dust, which results in reduced wear of the moving parts of the machine, and a more reliable operation of the tongues of the knitting needles 3 and 4.
- Blower means 2-8 and the corresponding hoses are fully protected in the closed chamber I, and gear 53 and the bearing faces of hub portion 36 and sleeve 10 are also located in a closed chamber 3 and protected from dust.
- lamps 56 are provided which illuminate the working area to permit observation of the knitting operations through the transparent walls.
- transparent wall portions 42 can be shifted in grooves 9b and 38b to provide openings through which the working area can be reached.
- the construction of the present invention renders it possible to enclose existent knitting machines of standard construction without substantial structural changes.
- the thread transporting means '17, and the thread guide 19 and 41 can be provided at the required positions in relation to the knitting stations although closed chambers I, II and III are provided in accordance with the present c-ircumferentially spaced openings 45, 48, 36 assure a uniform distribution of the air currents around the central axis of the machine.
- the blower connected to tube 49 and the exhaust fan conected to tube 44a, not shown, are preferably mounted in the hollow legs 8 of the machine. Due to the fact that the air streams out of openings 36 impinge the air stream passing through the gap between the needle cylinder and dial, particular turbulence is created in the region of the knitting operations so that removal of dust is assured.
