KNITTING-MACHINE NEEDLE.

Application filed May as, 1921. Serial No. 471,515.

To all whom it nmg concern:

Be it known that I, Anenn'r E.PAGE, a citizen of the United States of America, residing in Fla-tbus'h, -'in the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Knitting-Machine Needles, of which the following is a specification.

My invention relates to knitting machine needles of that class in which the needle is made in two parts in sliding relation to each other as distinguished from the more common pivoted latch construction. The object of my invention is to so combine the two parts of the needle that they can easily be manufactured, assembled and repaired and that the twoparts will be maintained in proper relation to each other under all conditions of the knitting.

In the accompanying drawing:

Fig. 1 is an enlarged side elevation of my improved needle mounted in the dial, which is shown in section. and indicating the operation in connection with the cylinder needles of a ribber;

Fig. 2 shows the same parts in other positions.

Fig. 3 is a sectional view on the lines 3 of Fig. 2.

Fig. i is an underside view of the sliding latch part of the needle.

My improved needle is shown as mounted in the dial 1), and I. will for convenience term the part A the needle body, while the otherpart B, I will call the sliding latch, although this latter performs or may perform other functions in addition to those which are performed by the ordinary latch. These two parts are in sliding relation to each other along their shanks, and each is provided with a suitable butt (1' (1)). Suitable cams in the dial or cylinder of the knitting machine acting on these butts, cause these two instruments A and B to be projected or withdrawn to manipulate the threads in an appropriate way for knitting.

l have shown my invention embodied in a type of knitting machine needle which forms the subject of an application for patent filed by R. W. Scott, April 14, 1921, Serial No. 461,195. a characteristic feature of such needle being that the latch part B to take the old loop from the shank of the needle part A, as the latter is projected to take the yarn to draw a new loop, and also with a forwardly projecting hook 5 to carrv a loop of yarn out beyond the upward path of the cylinder needle n, Fig. 2, at a certain stage in the knitting.

lily invention has to do with the means by which these two part A and B are maintamed 1n proper relation -'to each other, wlule free to slide upon each other, especlally agalnst the strain indicated in F ig. 2. For thls purpose I prefer to form the rear part of the needle body A both front and back of the butt a, vertically deeper than the forward part, and I cut in the side of thls rear part and in the side of the butt a an open groove C. This groove is not a slot extendmg through the needle body but is made m depth say about half the thickness of the metal plate from which the needle 1s made. By the term side I refer to a face which is lateral to the plane of the hook. using said term to distinguish from the front and backedges of the needle shank. The lower edge of this groove C is preferably a continuation of the upper or outer face :10 of the forward part of the needle shank.

The sliding latch B is provided with a narrow tail piece B, of about one half the thickness of the body of the sliding latch and adapted to fit slidingly in the open groove 0 in the side of the rear part of the needle body A.

The thinned tail piece B is slightly bent sidewise to form a spring (Fig. 4) which. acting against the side walls of the contalnlng groove in the dial, serves to maintain both parts under tension in the groove so that they will not become displaced by flying beyond the scope of action imparted to them. by the operating cams.

When the two parts are thus fitted, they present but the thickness of a single needle- (Fig. 3), and when the two are inserted in a needle groove of the dial D or the cylinder, as the case may be, the sides of the needle groove will keep the two parts of the needle laterally in place. At the same time the sliding latch B will be maintained in proper relation to the part A by the tail piece B" bearing against the upper and lower walls of the groove C in'the needle, and thereby the latch will be prevented from tilting under the pull of the yarn, Fig. 2.

lit)

The described construction is easily manufactured and the parts easily assembled, and no undue thickness of the needle results.

I claim as my invent1on:-

1. A knitting machine needle in two parts, comprising a needle body and a latch in sliding relation to each other, one of the parts having an open groove in its side to receive and uide a part on the other.

2. A knitting machine needle composed of ai needle body and a. latch insliding relation to each other, one having an open oove in its side to receive and guide a part on the other, said guided part being thinner than the rest of it.-

3. A knitting machine needle composed of a. needle body and a latch in sliding relation to each other, theneedle body having an open groove in the side of its rear part to receive and guide a tail piece on the slidin latch. I

4. g knitting machine needle composed of a needle bod and a. latch in sliding relation to each ot er, the needle part having its forwardshank adapted to support the latch and having its rear part of extra depth with an open 'roove in its side to receive and guide a tall piece on the sliding latch.

5. A knitting machine needle, composed of axneedle body and a latch in sliding relation to each other, one having an open groove in its side to receive and guide a bent tail piece on the other part.

In testimony whereof I have signed my 35 name to this specification. 1

ALBERT E. PAGE.
