I NEEDLE-CARRIER AND NEEDLE FOR KNITTING-IVACHINES.
Application filed August 31, 1914.
To all whom t may conocen.'
Be it known that l, Roninrr W. Sco'rr, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Needle-Carriers and Needles for which the following is a specification.
This invention relates to needle carriers and needles for knitting machines.
One object of my invention is. to provide a needle bed, carrier, cylinder or dial with an improved inserted-wall structure providing grooves for independently movable needles.
A further object is to provide said grooves with structures coperating with independently movable needles to prevent the needles from being accidentally withdrawn from their grooves.
In the accompanying drawings,
Figure l is a section transverse "to the axis of a cylindrical needle carrier and needles therefor, on the line lhl of Figs. 9 and 10.
Fig. 1a is an form of needle;
Fig. 2 is a section similar to Fig. l through a fiat or straight bed or carrier;
Fig. 3 is a side elevation of a single inserted piece;
Fig. l is a side elevation oi form of insert;
Fig. 5 shows another modification;
Fig. 6 is a perspective showing the forni of an inserted wall suitable for use in a dial or radial fiat bed;
Fig. 7 is a section on line 7-7 of Fig. 4l;
Fig. 8 is a section on the line 8-8 of elevation illustrating one a modified Fig. 5;
Fig. 9 is a sectional View showing the hottom or back of a needle in engagement with a needle groove formed by two inserts;
Fig. 10 is a similar view showing the coaetion of a needle of a different form with one of the grooves.
In the usual forms of independent needle knitting machines, grooves for movement of the needles with respect to their carrier by the action of cains on butts 1. ofthe needles are cut in the carrier, or formed Knittiiig-lvachincs, of
Specification of Letters Patent.

between walls inserted in grooves cut in the carrier, as well known in the art.
In the operation of such machines, especially of circular machines having automatic cam devices, difficulty has been experienced in retaining the needles within their grooves during `all of the operations.
Various devices are fai'i'iiliar in the prior art for hold ing the needles in position, such, for iiistance,.as endless rigid or spring hands encircling the cylinder, but such necessarily located with devices are respect to the needles at a point out of range ot' the reciprocal path of the cycle.
needle-butt in its working The dimensions of the needles employed 1n such machines have grown progressively finer, increasing the resiliency of the needles,
so that they are now often unable to resist stresses tending to lift their lower or butt ends out of their grooves.
Such stresses arise especially from the operation of the narrowing and widening devices or needle pickers, or trom the employment of 'adially movable cams, especially when said devices move at high speeds.
In the lat bed knitting case of dial knitting machines and machines, stresses tending to lift the needles out of their grooves are more common wi illes, the needles Hndei l avoid the tendency generally being duc to ih stiffer, coarse-gage neelhe leverage of the pull of .the fabric.
of the butt end of the needles to be withdrawn from their carrier by the devices shown in the drawings. As sho-wn inder 2 is provided ywith parallel in which Suchl walls or iiidei' in any instance. by ends with an un eled collar, such in Fig. 1, the needle cylgrooves 3,
are seated inserted walls or hars 4.
bars may be held in the cylnner usual inthe art, for
the engagement oi their beveled der-cut groove and a bevas described iii the patent to Harry Swinglehurst No. 1,089,021, March 3, 19141-, Such a bar ma,7 have the outline in elevation shown in Figs. 3 and 4.
In order to provide allel-sided slot capable formed from a throughout, the
inserts el may be a sul'istantially parof guiding a needle blank of even thickness gross cioss-section of the \ve .lgesliaped, as shown in Fig. 1, although an insert of the parallel iform shown m cross-section at 5 in Fig. 2- Kwill be operatlve when applied to the surface of a cylinder. hlt ot whatever shape lthe general cross-sectional area of such walls may be made, I prefecto form them with -one facet offset longitudinally ot the bar to provide a shoulder 7, thus restricting the entrance of the groove formed between two like inserts in width with respect to the .width of the groove at a deeper part ot' said slot. This form may be given to the ybars or inserts by rolling or drawing them, or the shoulder 7'1nay be formed by reducing or grooving the bar 4 along one face.
The shoulder 7 preferably will present a rounded surface or be formed at an angle not quite a right angle.
When the carrier is built up by the insel'- tion ol' the bars lin the grooves of the cylinder 2,'the shoulder 7 will be at such a distance above the periphery or face of the carrier as to provide between said periphery or tace and said shoulder a space wide enough to -lreely receive the oll'set portion 10 of theineedles 1, which may be l'ormed in any convenient manner, as by bendinev said needles out o1' line through a part ot their length, as 'shown in Fig. 1", or by oil'setting a tail or pal't o'lI the needle, which may be reduced in thickness, as shown at 11, Fig. 10. '.lhe resilience ot the needle will then enableit to be 'l'oreed into its groove through the restricted mouth thereof. or to be rcmoved in the same way by the application of, considerable torce, but during their no1'- lnal operation the needles 'will be held in their grooves by, the engagement of theiil portions 10 or ll with shoulder 7. 1t will be noticed that the interlocking engagement ot the needle is with a part near its butt, where the needle most needs support. For some uses an offset or bend `l0. such as is shown in Fig. 5), which is so short and sti ll` as to necessitate the removal o'l' the needle endwise from its groove may be. employed. 0r when a needle ot this type is to be employed, 1 may cut the oll'set l'aee G a 'ay at one end of the bar, prel'erably at a point beneath the range o'll r aciprocation olE the needle by the cams, as shown at 2t). Fig. i), to permit .the needle to lbe moved out ol' its groovegwhen the ollset part 10l is in a part o'l' the` groove hav-'ing no l'are and no sh..ul der 7.
The structure shown in Fig. l for a straight or llat bed is similar to that shown in Fig. l except that there is in this case no occasion 'for making the inserts 5 wtalge-shaped. For either thesituation of Fig. 1 or the situation o'l` Fig. 2, l may l'orm the insert or needle wall by another construction, but with the sume etl'ect, for instance, in the manner shown in Figs. 4i and 7. 1n this form of my device the wall is built up ot plates -12 and 13, both of said plates being cut to the neces` sary form in elevation to enable them to be fastened in the grooves of the carrier. The plate 12 is llat or wedge-shaped in cross section throughout its length, while the plate 13 is formed with a slot or window 1'1-, the outer edge o' which forms a shoulder similar to the shoulder 7, and for the same purposes.
llhe slot 1-t is of such width as to bring its lower edge at or below the level of the surface of the carrier in which it is inserted.
While in some situations the plates 12 and 1?) are sullieiently stitl when merely locked in place. in the grooves 3, l prefer to attach them together by soldering, brazing, or, as illustrated in Figs. et and 7, by spot-welding at the points 15.
A similar structure results when, as shown in Figs 5 and S a flat bar 16 is similarly joined to a U-shaped section 17, as by brazing the two together as indicated at 18.
As shown in Fig. (3, I may apply my device to an inserted wall dial, for instance such a structure as that shown in the patent to .llarry Swinglehurst, No. 1,025,169, May 7, 1012, byl forming the bars :v of the said patent on one side thereof with overhanging ledge or shoulder 19 similar to the shoulder 7, to cooperate with the needles having otl' sets 10 or 11.
What I claim is:
1. In a knitting machine the combination of needles having an otliset portion with a needle carrier having inserted spacing walls for guiding the needles on the surface of said carrier, each wall having a surface iny terloclt'ing with said olliset portion of a needle to prevent movement o'l' the needle away lrom the carrier.
L). In a knitting machin. a needle carrier having thereon spacing walls each having one plane surl'ace and one surl'aee presenting an overhanging shoulder, in con'ibination with independently movable needles held between said walls each having a lateral o'l'set in engagement with one ot said shoulders.
3. A needle carrier for knitting machines having therein a system of parallel grooves, and inserted walls in said grooves each having an ollset surl'aee parallel with the diret-- tion o'l. their greatest length, said surface being spaced away from the surface of the carrier and overhanging the space between Aadjacent bars.
4. As an article of manufacture an insert or wall 'for inserted-wall needle-carriers for knitting machines, consisting of a bar having a longitudinal shoulder on one face parallel with and near one edge thereof.
5. As an article of manufacture an insert or Well for4 inserted-Wall needle-carriers for name to this specifcaton in the presence of l n1tt1ng nnachnes7 conslstlng of a bar havtwo subscrlblng Wltnesses. lng at its ends a formatlon enabhng 1t to be held in place, and having a longitudinal ROBERT W' SCOTT' Shoulder on' one face parallel with and near Witnesses: one edge thereof.
