MECHANISM FOR CONTROLLING KNITTING NEEDLES IN PLATING RELATIONS.
Original application filed March 10, 1927, Serial No.
This application is a division of application Serial No. 174,176, filed March 10, 1927.
This invention relates to mechanism for controlling knitting needles in plating relation, and particularly to means for moving outwardly predetermined needles when normal plating is to occur thereat.
In order that the principle of the invention may be readily understood, we have disclosed one embodiment of the invention as well as certain instrumentalities whereby the invention may be practised.
In the drawings, Fig. 1 is a plan view of the sinker or web holder bed ring and showing in horizontal section the cams of the sinker cam ring, the top plate of said ring being removed;
Fig. 2 is a detail in plan of the sinker ring and certain parts in the grooves thereof;
Fig. 3 is a vertical transverse sectionupon the line 33 of Fig. 1 and looking in the direction of the arrows in said figure, the needle being shown in its inner position; and
Fig. 4 is a perspective view of certain instrumentalities employed with this form of our invention.
In the patent to Robert H. Lawson, No. 1,605,895, dated November 2, 1926, there are disclosed means for efiecting reverse plating by the action of casting ofi mechanism, whereby lengthwise extendin stripes maybe formed in hosiery or other itted fabrics. In the patent to Robert H. Lawson, No. 1,605,896, dated November 2, 1926, there are disclosed means for efiecting, reverse plating through the action of instrumentalities, the transverse movements whereof are selectively governed, wherebya great variety of patterns may be provided. In the present application means are disclosed particularly constituting improvements upon or adapted to be used with the mechanism shown in said Patent No. 1,605,896, but which may be used with mechanism such as shown in said Patent No. 1,605,895. The mechanism here shown is also of general application.
The web holder bed ring is indicated at 1, it having radial or transversely extending grooves 2, for receiving the regular web hold? ers or sinkers indicated at 3in the several figures and also for receiving the special instrumentalities indicated at 4 in said figures. The sinker cam ring, the top plate whereof has 174,176. Divided and this application filed January 8,
1928. Serial No. 244,073.
Between the pathways 8 and 9 is a cam 11 of general segmental form, and between the pathways 6 and 8 is acam 12 also of general segmental form. The said cams 11 and 12 are sufliciently spaced from each other to receive the butts 10 of the specialinstrumentalities when the same have been directed thereinto in any suitable manner, as, for example, by selective means such as shown in the Lawson Patent No. 1,605,896. It will be noted that the special instrumentalities 4 are of greater length than the regular sinkers or web holders 3, and also that the outer'ends and butts of the special instrumentalities 4 are thickened so as to occupy the entire width of each groove 2. The segmental cam 11 is provided with an inwardly sloping or inwardly extending end part 14, the purpose of which is to move the special instrumentality radially inward at an'earlier point circumferentially considered, or, inother words, at an earlier point in the stitch forming operation than the regular web holders are moved inward at or near the casting ofi point. The purpose of this action is substantially. that described in said Lawson Patent No. 1,605,895. Slightly circumferentially beyond the point where the special instrumentalities are so moved inward, that is, to the left thereof viewing Fig. 1, the inner edge of the cam 9 is sloped inward, as indicated at 15, such slope terminating in the point 16 circumferentially beyond which the edge of the cam 12 slopes again outwardly as indicated'at 17. The purpose of the slope 15 u to the point 16 is to force the regular we holders in wardly in the regular stitch forming opera.
tion.
At an earlier point circumferentially considered than the inwardly extending end part 14, the cam 11 is provided at its outer edge with an enlargement or radially thickened cam of substantial circumferential extent in dicated at 18 in Fig. 1. The purpose of this enlargement is to cause the special instrumentality 4 to be moved slightly further outwardly by engagement with the butt end thereof.
Assuming that the mechanism is used with that type of selective means shown in the Lawson Patent No. 1.605.896. the butts 10 of those special instrumentalities 4. which are selected for reverse plating, ride in the pathway 8, the other special instrumentalities 4. being those at which normal plating is to be effected, remaining in the outermost pathway 9. In the continued movement of the parts. the said selected special instrumentalities 4 are projected inward by the inclined edge 14. and very shortly thereafter the regular web holders or sin kers 3, whose butts 7 ride in the inner pathway 6. are also projected inward. The mechanism disclosed constitutes one type of means for effecting normal and reverse plating and is selected merely for purposes of illustration of means which we hereby term primary means for effecting normal and re verse plating.
In accordance with our invention, we provide means for effecting deflection of the needles at the hook end and particularly for outwardly deflecting those needles upon which normal plating is to be efleeted. IVhile we have shown regular web holders or sinkers 3 and also certain special instrumentalities 4, it is clearly to be understood that our invention is not limited to mechanism wherein special instrumentalities are employed.
The needle grooves 19 are here shown as of usual depth, but our invention is not limited in this respect. IVhile thc needle movement may be effected in any suitable manner. it is here shown as effected by a hook or bent part 20 formed upon each of the special instrumentalities 4, as shown most-clearly in Fig. 4. While the hook 20 or like formation might be employed upon a special instrumentality, which itself is shaped to cooperate in effecting reverse plating at desired times, it will be evident that the special instrumentality 4'is not provided with a formation to cooperate in effecting reverse plating. In other words, the construction of Fig. 4 is particularly intended for use where reverse plating occurs in some manner or through some instrumentalities at certain needles, and it is desired to change from reverse plating to normal plating. The special instrumentality 4 is provided with the usual butt 10. and the latter engages the edge 18 shown in Fig. 1 for the purpose of effecting outward movement of the needles against the tension of the spring hand or hands 22. The needle represented at 23 is shown as provided with a butt 24.
It is clearly to be understood that our invention may be employed in mechanisms where the radial grooves of the web holder bed ring receives only regular web holders or sinkers. In other words. our invention is not limited to any particular means for cffccting the outward deflection of the needles. The outward deflection of the needles is. however, for the purpose of effecting change from reverse plating to normal plating relation. An important object is to secure a sharp or well defined change from reverse to normal plating.
