  • This type of cylinder construction is incorporated in circular knitting machines which are generally referred to in the art as sinker-top or open-top machines.

  • the cylinder 20 also includes means for guiding vertically disposed needles 28 about the outside surface of the cylinder 20, and such means may include grooves formed into the cylinder wall, or alternatively, insert members 30 may be welded, soldered, or otherwise afiixed to the outside cylinder wall to receive needles 28 about the entire cylinder.
  • a sinker dial 32 is affixed to an upper end of the cylinder 20, as by means of set screws 34.
  • the sinker dial 32 is slotted across its upper surface to receive the same sinkers 24 that are received in the slots 27 of the cylinder, and the slots in the sinker dial are appropriately positioned with respect to the slots of the cylinder in a well known manner.
  • a typical construction of this type is illustrated in Grothey Pat. 2,163,461, and the disclosure of that patent is incorporated herein by reference to further describe the well known features of this art which are not a separate part of the present invention.
  • a supporting ring means 22 is integrally formed on an end portion of the cylinder 20 to support the horizontal movements of sinkers 24 on the upper end of the cylinder.
  • the uppermost surface of the supporting ring means is heat-treated and hardened to reduce wear from the frictional contact of operating sinkers 24 on the horizontal surface upon which they are riding.
  • a hardened surface for the supporting ring means it is well known that over a period of time in the operation of the machine, grooves are formed in the surface from frictional contact of the sinkers with the hardened surface. The substantially downward pull of the knitted fabric, as it is being produced, against the inner edges of sinkers 24 further aggravates and accelerates this wear condition.
  • an important feature of the present invention is to sufliciently dissipate frictional heat away from the hardened surface so as to substantially reduce the rate of wear thereon, and other embodiments of the invention will be described with reference to a provision for an adjustable or replaceable bearing surface for the supporting ring means.
  • a groove 36 is formed into the upper horizontal bearing surface on the supporting ring means 22, and the groove extends about the entire annular end of the supporting ring means of the cylinder.
  • the groove 36 functions to increase the surface area of the upper end of the cylinder so as to better dissipate heat during normal use of the cylinder when sinkers are riding on the bearing end of the cylinder, and also to make possible more uniform heating and cooling during the process of heat-treatment. Further, the groove 36 functions to reduce the amount of surface actually in contact with the sinkers so that there is less frictional heat generated in the first instance.
  • passageways 38 are formed through the supporting ring means 22 so as to communicate between the upper bearing surfare of the ring, and an inner vertical wall surface of the cylinder 20.
  • the passageways 38 communicate with a second continuous groove 40 which is formed through at least a portion of the cylinder wall so as to complete the communication of the passageways with the upper groove 36 and with the inner wall surface of the cylinder 20.
  • the passageways may be in the form of elongated slots 38, or alternatively, they can be circular openings which are bored or otherwise formed through the supporting ring means 22.
  • the annular grooves 36 and the second annular groove 40 are preferably continuous grooves formed about the entire cylinder assembly, and both grooves by exposing greater surface areas function to facilitate heat-treatment during the initial manufacture of the assembly and also to dissipate heat during the subsequent use of the assembly.
  • passageways 38 be formed as shown in FIG. 1a so as to provide concentric rows of elongated slots about the annular end of the cylinder. Further, the elongated slots are placed to overlap one another in adjoining rows so that each sinker element 24 passes over at least one passageway 38. It is to be especially noted however that the botom portions of the sinker elements do not ride directly on the surface in which passageways 38 are formed. The reason for this arrangement is to provide an improved construction for reducing frictional contact between the sinkers and the bearing surface, and for dissipating heat which is generated from the frictional contact of the sinker elements with the supporting ring.
  • passageways 38 provide for more uniform heating and cooling during heat-treatment, thus facilitating the relieving of internal stresses and strains in the cylinder member and minimizing any tendency to distort. Also, the arrangement shown permits a more rapid and efficient cleaning of the sinker top machine, while the machine is stationary or in operation. Because of the novel arrangement of passageways 38 which communicate between the supporting surface for sinker elements and an inner wall surface of the cylinder 20, there is provided a construction wherein the sinker elements and the topsurface of the supporting ring means can be at all times maintained free of lint and other accumulations.
  • Pneumatic cleaning devices of well known constructions may be utilized to force air downwardly between the sinker elements, through the passageways .3 8, and from there inwardly through the groove 40, thus carrying all lint and other particle accumulations away from the knitting elements.
  • air may be forced through the passageways either by blowing an air-stream therethrough or by drawing air through with a vacuum creating means.
  • FIG. 2 illustrates a modified form of construction wherein the upper supporting ring surface is merely an extension of the cylinder body 20.
  • the passageways for the FIG. [embodiment are provided by a plurality of equally spaced borings '42 which are horizontally disposed about the upper end of the cylinder 20, and these horizontal borings 42 provide for a communication between the upper bearing surface of the supporting n'ng means 22 and both of the vertical walls of the cylinder 20.
  • FIG. 2 embodiment also illustrates av cylindrical shielding member 44 which may be attached to the inner vertical wall of the cylinder 20 so as to be spaced away from the outlets of the horizontal openings 42.
  • the shielding element 44 may be made of any suitable material, and may be attached to the cylinder wall in any well known manner, such as by the illustrated bolts.
  • FIG. 3 is a variation from the FIG. 2 embodiment and illustrates a further manner in which passageways can be formed to communicate with an upper bearing surface of a cylinder and an inner vertical wall of the same cylinder.
  • an annular groove 36 is formed into the upper bearing surface of the supporting ring means 22, which is an integral part of the entire cylinder body.
  • a second continuous groove 40 is formed into a vertical inner wall of the cylinder, as was discussed for the FIG. 1 embodiment, and finally, a plurality of equally spaced holes 38 are drilled to complete a communication between the two annular grooves.
  • the annular grooves also provide for increased surface areas and improved heat dissipation, and the plurality of openings 38 provide for the passageways which must communicate between the upper bearing surface of the cylinder and an inner wall surface of the same cylinder.
  • FIG. 4 illustrates a still further variation in the FIG. 9
  • the second annular groove 40 is formed in a slightly different configuration from that described in the other embodiments.
  • the groove 40 is formed in such a way that passageways 38 can be drilled or formed at an angle to an upper groove 36. In this manner, the formation of the assembly is facilitated by providing an easy arrangement for drilling equally spaced holes as the passageways 38, and further, the angled passageways more quickly carrying away lint and other accumulations when pneumatic devices are used to flush air downwardly through the cylinder.
  • FIGS. 5 through 9 illustrate sinker top circular knitting machines incorporating further features of the present invention.

  • the cylinder body includes an upper end extension 22 which may be considered the equivalent of a supporting ring means in the sense of previous discussions for supporting rings associated with cylinder assemblies.
  • the FIG. 5 embodiment differs from previously described assemblies by a provision for a replaceable and adjustable bearing member 46 which is mounted at an upper end of the cylinder 20 so as to present a bearing surface 48 in alignment with or preferably slightly above the bearing surface 50 of the cylinder end.
  • the bearing member 46 may be in the form of a metal ring element which has been previously heat-treated to provide the necessary hardness for a bearing surface for sinkers. Significantly, this separate ring element can be heat-treated to hardness different from that of the cylinder body when operating conditions dictate.
  • the ring element can be held in place at the upper end of the cylinder 20 by set screws 52, or by any other equivalent means.
  • the bearing member 46 is formed and mounted to leave a gap or annular groove 36 about the entire upper end of the supporting ring means of the cylinder 20.

  • the bearing member 46 is constructed to provide an annular groove 36 in the upper surface of the cylinder end when the bearing elements making up the member are mounted in their final positions.
  • FIG. 7a illustrates elongated slots or passageways 66 which are formed through an upper end of the cylinder to provide a communication between the upper bearing surface of the cylinder and an outside vertical wall surface of the cylinder.

Spacers 55 perform the added function of insuring proper location of bearing surface 57 with respect to the sinker dial 32.
  • Integrally associated with bearing member 46 are sinker-guiding fins 59 which insure true radial movements of the sinkers and eliminate any tendency for lateral displacements of the sinkers during the knitting process.
  • bearing member 46 incorporates a hardened bearing surface 57 located at a height above ledges 61 formed by adjacent sinker-guiding fins as shown in FIG. 9. This feature facilitates heat-treatment of bearing member 46, reduces the area of contact between the sinkers and the bearing member, minimizes the possibility of lint or other accumulations from packing below the sinkers in the grooves formedby adjacent guiding fins 59, and permits the use of pneumatic means to keep the fin slots below the sinkers clean of foreign matter. It is also a feature of the FIG. 9 embodiment that a substantial air space is left below the sinkers 24 so as to reduce frictional contact and to facilitate a removal of lint from beneath the sinkers. As shown in FIG. 9, a substantial length of lower edge portion of the sinker 24 is unsupported and out of contact with any surface structures at the upper end of the cylinder.
