FIG.
Nov. 10, 1959 v. LOMBARDI KNITTING MACHINE Fild Feb. 24, 1956 3 Sheets-Sheet 2 INVENTOR V/A/C'A/T LfiMBAAD/ AQOR United States Patent KNITTING MACHINE Vincent Lombardi, South Miami, Fla. Application February 24, 1956, Serial No. 567,687
12 Claims. (CI. 6650) This invention relates to knitting machines arranged to knit both the forward and return feeds from a wrapyarn-feed.
When knitting of the return yarn by a multiplicity of needles is desired, it is important that the knitting wave move in the reverse direction to the normal knitting wave (whereby the forward yarn is knitted), so as to avoid binding and permit the yarn to flow freely as the loops are drawn out. While this is most important in the operation of needles, it is also important in the operation of other knitting elements such as sinkers.
With the foregoing and other considerations in view, the present invention contemplates the provision of particularly simple, eflicient, and effective means for imparting a reverse knitting wave to knitting elements engaged in the knitting operations on the return course from a warp-yarn-feed.
The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accom panying drawings, in which:
Figure 1 is a transverse sectional view of a portion of a circular knitting machine embodying the invention;
Fig. 2 is a vertical sectional View along the line 22 of Fig. 1;
Fig. 3 is an enlarged side View of the reverse-knitting Fig. 4 is a perspective view thereof; and Figs. 5, 6, 7, 8 and 9 are diagrammatic views illustrating the operation of the machine.
While, in Figs. 1 and 2, the invention is exemplified in connection with a needle-bed in the form of a stationary needle-cylinder, arranged to knit jersey fabric, it will be appreciated that the invention is adapted for use with various types of knitting machines and in connection with various forms of knitting elements other than needles. As exemplified, the cylinder 20 has independent latch needles 21 in the slots 22 thereof. Means for setting up selective needle-advancing waves moving about the cylinder are provided as shown in Figs. -9. These may be of any well known or suitable type, and, as exemplified, include selective mechanism and needle-advancing mechanism at least one of which rotates about the cylinder in one directionthe direction of movement of main-yarnfeeds 24, if provided as in the exemplified form, and of the forward swing of wrap-yarn-feeds 25. In the present instance, this mechanism is shown diagrammatically in the form of cams 26, a selective drum 28 and a pusher mechanism shown diagrammatically at 30, and jacks 31, and jack-retracting means 331:, all as shown in my Patents 1,797,006, dated March 17, 1931, and 2,740,277, dated April 3, 1956. Alternate needles have long butts 32 the intermediate needles have short butts 33, so that low gee 2,911,807
The left-hand cam 35 in Fig. 6 is shown as so operating as it moves toward the right after the wrap feed above it has fed yarn to a group of needles by a swing to the right. The earns 26, 34, and 35 and the wrap-feedoperating mechanism 27 form, in the present instance, part of actuating mechanism 38 which revolves around the needle cylinder.
When the return movement of a Wrap feed has fed yarn to a group of needles in the opposite direction, as by a swing to the left (Figs. 5-9), a specialcam 40 is adapted to act on special butts 42' of the needles to retract them as it moves from right to left. The righthand cam 40 in Fig. 8 is shown as so acting, at it moves to the left over a reciprocating course 44. Each cam 40 and its associated mechanism are carried by a carriage 45 (Figs. 1 and 2) forming a partof the actuating mechanism 38. The cams 40 are constructed with operating cam surfaces 46, and with curved slip surfaces 48, and are mounted for swinging movement on shafts 50 against the tension of springs 52, so that they will swing clear of any butts 42 which may accidentally be in their path during the inoperative strokes of their reciprocation. However, as in the exemplification of Figs. 5-9, the setting of the selective mechanism is preferably such that no butts 42 will be intentionally moved into the path of the inoperativestroke of a cam 40.
The shaft 50 is mounted on a driven arm 55 formed with an arcuate gear 56 meshing with an arcua'te gear 58 of smaller radius on a segmental driving member 60 pivoted on a shaft 62 on the carriage 45. Also mounted on the carriage 45 is a gear 64 meshing with an annular gear 65 mounted on the cylinder 20. Fixed to gear 64 is an eccentric in the form of a crank 66 to an end portion of which is secured one end of a piston 68 the other end of which is secured to the segment 60 at a suitable point between the shaft 62 and the gear 58. Thus, as the crank or eccentric 66 rotates, the arm 68 connected to the eccentric 66 and driving member 60 will be reciprocated, and thus the segment 60 will be reciprocated, as will the cam 40, while the carriage moves more slowly about the needle cylinder.
In Figs. 5-9 there is shown one form of operation in an arrangement where spaced wrap feeds are employed to provide ten-Wale stripes in a jersey fabric. It will be appreciated, however, that the invention is adapted for the production of much wider stripes, for the production of fabric from wrap yarn alone, as formed by overlapping wrap feeds, for the production of rib-stitch fabric, and/ or for the production of a wide variety of variations in types and characters of fabric.
As shown in Figs. 5-9, wrap yarn is knitted by groups of needles indicated at a, c, e, g, and i; and main yarn is knitted by groups of needles indicated at b, d, f, h, and j, and inlaid by the groups of needles which knit the wrap yarn. A main yarn feed follows swings of the wrap feeds in one direction, and a main yarn feed follows the swings of the wrap feeds in the opposite direction.
In Fig. 5, a cam 40 is shown knitting reversely-extending wrap yarn at a, a cam 35 is about to knit forward ly-extending wrap yarn at c, another cam 35 is knitting main yarn at d, a cam 40 is passing thru the inoperative- Patented Nov. 10, 1952 the knitting (see Fig. 8) of yarn formed by the return swing of the wrap feed at g where the knitting of yarn from the forward swing is just being completed, and the inlaying of a main yarn is being conducted at it (this operation also being shown at e of Figs. 6 and 7). The sequence of operations proceeds as shown in Figs. 6-9.
Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
