Specification of Letters Patent.

Patented July 1' 1913.

Application filed November 18, 1910. Serial No. 593,097.

of a foreign substance such as a broken 7 needle, theyield ing of the evener preventing the needle towhi'chthe yarn is sunk from being bent and interfering-with the succeeding sinker, and thus, in turn, affecting the succeeding needle and finally causing a" smash up.

The invention consists in the fen-ores and combination and arrangement of parts hereiiiafteidescribed and particularly pointed out in the claims.

In the accompanying drawings :Figure l is a sectional view of a part of a knitting head embodviiv ni invention )ai'lsbein k: in elevation; Pig. 2 is a planview of; the parts shown In Fig. l; and Fig. 3 is a view of one member of the evcncr detached; Fig.

though it will be understood that I donot liniit myself in this particular.

In these drawings, 1 indicates a part of the needle cylinder in grooves on the out-side of which the spring needles 2 work.

3 is the presser ring encircling the row of needles, i the sinkers, 5 the sinker cam, 6 the web holders, 7 the web holder cam, 8 the cover rin for the sinkers and 9 the top plate of the knitting head.

Upon the top plate or sinker can section is mounted a bar 10 extending radially inward and carrying the needle evener. This evcner ma be variously constructed, but in the form shown it consists of an upper member 11 fixed t0 the bar 10 by a shouldered screw 12 and by a shouldered stud 13, the latter being held by a nut 14, and the evener also consists ofa member '11, having its face 14' which contacts with the needles normally fiush' with the upper fixed part of the evener. This lower part is yiel'dinglymounted to have movement radially in relation to the center of the machine, and for this purpose it is slotted at lfyand is held up to the upper member, and guided in its movement by the shouldered screw and stud above mentioned, which pass through the slot. A spring 17 is arranged within thesl'ot, bearin; at its inner end upon the shouldered" screw, and at its outer end upon a shoulder 18 on a pin 19 which passes through an open' ing in the shouldered stud;- and bears at its citer end upon the interior wall of the mo\' able member of the cveiier. its outward movement under the action of the spring, is limited by its rear interior wall striking the shoulder on the screw, and this maintains j the movable partof the evener Flush with the fixed portion as above 'described.-

The purpose of the evener is primarily to even up the needle row at'the point where the yarn issunk by causing any needle which is bent out of shape, or for other cause is not inproper position, to be straightened up sinkers, thereby insuring the even sinking of the yarn and the formation of loops of equal length.

By my construction the lower member of the evener is free to slide radially to compensate for any excessive pressure on the needles, this yielding action being permitted by the spring connected with the lower member ofthe evener allowing it to retract and permitting the needle to bend toward the center of the machine Without creating sufficient resistance to cause interference with the succeeding needle or sinker. After the obstruction has passed, the evener is returned to normal position by its spring. As above stated, the yielding evener may be variously constructed and arranged, the essential feature of the invention being an evener that. will automatically take care of.

any excessive pressure brought to bear upon the needles atthe time the sinking of the yarn takes place. Instead of a twopiece construction, the evener may be made in one The evencr, in

results.

,k'pieee, and yieldingly mounted by a spring, or, as shown in Fig. 5, a single evener men"- ber may be used pivoted at 20 and pressed by a spring 2L against a stop 22 on the bar 10, so that when excessive pressure occurs, the evenerwwill yield'in the direction of travel of the needles indicated by the arrow, the evene'r being returned by the spring against the stop'when the undue pressure is relieved by the passing of the obstruction. I have also illustrated at 24 the clearer plate for smoothing down the fabric and clearing it of obstructions, and at 23 is shown the presser wheel, but these partsform no part of the present invention As one instance of the utility of this invention,- I \vouldmention that the evencr will yield when an obstruction-occurs inv the throat of the sinker and is pressed against the needle by the advance of the sinker, and

this obstruction-may lie present at either a single sinlcer'or may span several sinkers. This conditionis liable to occur with some frequency in the operation of themachine, and the yielding evener will take care of this obstruction and prevent disastrous I claim as my invention '1. In a sprn'ig needle knitting machine,

needlcs, sinkers, an evener for the spring needles maintainingnor'mal position under ordinary conditions, said evener being yieldthe combination of. the needle bed, spring 3. In combination in a spring needle knit-V ting machine, a needle bed, needles, sinkers,

a sinkercam and a two-part needle evcner to engage and even up the needles, one part being rigidly mounted and the other part 'being yieldingly mounted, the rigid member being above the yielding member, and stop means to hold the yielding member in a certain relation'to the rigid member, substantially as described.

4.. In a spring needle knitting machine, a needle bed, spring needles, a resser ring outside of the needle row, a presjser inside of the circular row of needles, radial sliding sinkers on the outside of the needle row, and a yielding evene-r on the inside of the needle rowto engage the hook endsof the needles when raised, said yielding even er being located adjacent the point where the yarn is sunk to the. needles, substantially as described.

Inwtestimony whereof, I affix my signa ture in presence w tnesses.
