CIRCULAR KNITTING MACHINE FOR STOCKINGS AND THE LIKE Filed Nov. 10, 1949 Vtwramszu d /m1: PPE 6 01. u l/PO Patented May 6, 1952 cIRcIiLAn KNITTING MACHINE FOR STOCKINGS AND THE LIKE Carlo Camnasio, Giovanni Aurelio Venturelli, and Giuseppe Colalupo, Milan, Italy, assignors to Oflicine Moncenisio, gia An. Bauchiero, Turin, Italy, a corporation of Italy Application November 10, 1949, Serial No. 126,562 In Italy November 17, 1948 This invention relates to circular knitting machines for stockings and the like having one or two needle carrying cylinders and has forits object improved means in such machines for the transmission of the impulses of the cam discs or drum which forms the actuating member of the machine to the various members to be actuated.
In the machines at present in use, each transmission is carried out by means of levers and rods acting under traction or thrust, the delicate and complicated construction of which impedes the movements of the machines and makes their operation uncertain.
According to the invention each transmission is a thrusting transmission formed by a small tube with a flexible incompressible core and which is curved in such a way as to connect the actuating member with the member to be actuated, and following the most suitable path along the intermediate parts of the machine taking in account the construction and the use of the machine.
All the levers, pivots and rods are thus dispensed with and the cylinders of the knitting machine are only flanked by small tubes, more or less curved, which are of no encumbrance.
In the accompanying drawings:
Figure 1 shows one form of a circular stocking knitting machine with two needle carrying cylinders, on which the improvement according to the invention has been fitted;
Figure 2 shows the drive with a cam drum;
Figure 3 shows a side elevation, in part in section of the mechanism for selecting the needles in the upper cylinder;
Figure 4 is a. plan view of said mechanism;
Figure 5 is a front view of the same mechanism, and
Figure 6 shows a longitudinal section of a portion of a transmission.
In Figure l the base of the machine is denoted by I having at its upper end a box 2 where are mounted the means for transmitting the motion of a motor (not shown) to the different members of the machine. Above this box and offset therefrom is fixed the support 3' in which the needle-carrying cylinders 4 and 5 are mounted for rotation, and in the lower part against the base I and coaxial with the needle carrying cylinders there is a collecting receptacle 6 for the finished stockings.
n the side of the machine and on the box 2, rotationally mounted is the cam drum I which is actuated by a ratchet system of the usual type, and which carries as many cam discs as there 6 Claims. (01. 66-154) are drives to be effected in the machine, each disc carrying one or several cams 9 having positions and heights suitable for producing the required movements.
In Figure 1 only two drives are shown, that is to say the drive of the movable sinker carrying disc in the lower orifice of the upper needle carrying cylinder 4, and the drive of the needle selecting cam in the upper cylinder 4.
The driving member for each of the drives is installed opposite the cam drum I, and for this purpose there is a support III in which the movable heads II of the different driving transmission members are arranged.
Each of these members is composed of a simple tappet as indicated at I 2 in Figure 2, and between the said tappet and the corresponding cam 9, preferably a lever I3 pivoting on the stationary support In is interposed. Starting at the fixed support I0 a small tube I4 extends terminating opposite the member to be driven. Said tube I4 contains inside a flexible, incompressible core by means of which the displacement of the tappet I2 is transmitted in its entirety to the driven member or receiver.
In the case of the drive of the sinker carrying discs of the upper needles cylinder, the drive which must cause an axial displacement of a rod (not shown) situated in the interior of the needles cylinders is produced by means of a rightangled lever I5 of which one arm rests against the end of the said rod, and the other arm abuts against the extremity of the receiving member I6 of the transmission situated in the extremity of the tube and supported by a stationary upright II. In this way when the cam 9 of the drum 1 imparts a determined vertical displacement to the tappet I 2, the receiving member I6 undergoes an equal horizontal displacement, which is transmitted to the right-angled lever I5, and consequently to the vertical rod mounted inside the cylinder 4, thus causing the sinker carrying disc of said upper cylinder 4 to sink.
In the case of another drive such as, for example, the drive of the mechanism for the selection of the needles in the upper needles cylinder, the tappet I2 opposed to a cam disc of the drum 1 transmits its displacement to an horizontal rod I8, movable in the guide III, the extremity of the rod operating on the shaft 20 of the blade 2| (Figures 3-5) which functions as a selector for the needles and is mounted axially movable against the spring 22 in a support 23.
As is known, the selection of the needles in the upper cylinder is made by means of a blade 2| 3 which, as is shown in Figure 5, can occur at an interval in the running of the needles where the changeover takes place between the single guide 24, and the two superposed guides 25 and 25'.
The efiect of the drive is that the blade 2l, which normally allows the free passage of the needles from the guide 24 to the guide 25, forms a prolongation of the guide 24 and acts as a gradient which forces the needles to rise into upper guide 25. This takes place when the cam 9 of the corresponding disc 8 of the drum I acts on the corresponding tappet l2 and the rod l8, moving forward, causes the displacement of the shaft 20 of the blade 2|.
The operation of the machine is quite conventional but it is obtained in a manner which eliminates the drawbacks of the transmissions as at present used which, because of their complicated nature, made known knitting machines unreliable in operation and rendered them cumbersome and difficult to look after.
For this purpose, between the support It), where a guide H for a tappet I2 is mounted, and the upright ll of the rod 15, and between the support [6, where another guide II is mounted, and the guide 19, a transmission is disposed which is contained in a fiexible tube M which is arranged in the machine in such a manner as to cause it to follow a path which is the most adherent possible to the intermediate stationary parts of the machine so that it does not increase the space occupied by the machine nor impair the visibility and the easy and direct accessibility to all other members of the machine.
In order to ensure the transmission of motion from the end, where the control member is arranged, the tube 54 contains a flexible but incompressible core constituted by spherical pellets alternated with pellets each having two flat endraces on which abut the tWo adjacent spherical pellets.
. Fig. 6 shows in axial section one portion of the said transmission. In this figure the tube i4 is seen, which is filled with a set of pellets 2B of a spherical form alternated with pellets 2'1 of a substantially cylindrical form, each ending at the two ends by fiat faces against which abut the two adjacent spherical pellets.
The tappet l2 of a guide as H abuts against the first pellet, while the lastpellet abuts against the rod it or iii adapted to slide in the corresponding guide at the other end of the tube l4.
By the construction described, it is possible to allow a considerable transverse play to the internal core formed by the set of pellets 28 and 27, which renders the tube It so flexible, that it ma be disposed along a path comprising several curves, even such of a small radius.
On the other hand, the transverse play of the pellets in the internal core does not hinder the function of the transmission because even though the pellets move transversely in relation to the axis of the tube N no jamming is produced nor a reduction of length of the internal core takes place.
This is due to the fact that in all relative transverse positions of the pellets 26 and 21, the spherical surfaces of the pellets 26 are constantly abutting on flat surfaces of the pellets 21 and the relative distance of all pellets 26 remain always unaltered.
Thus, the flexible core of the transmission maintains always an invariable length whatever the path may be along which the transmission is disposed.
