KNITTING MACHINE NEEDLE AND METHOD OF MAKING SAME Feb. 24, 1948.

mm- 2 llll'llllll w-ullm- Patented Feb. 24, 1948 KNITTING MACHINE NEEDLE AND METHOD OF MAKING SAME Roy Charles Amidon, Reading, Pa., assignor to Vanity Fair Mills, Inc., Reading, Pa., a corporation of Pennsylvania Application June 14,1945, Serial No. 599,493

\ 11 Claims.

My invention relates to needles of the kind disclosed in my Patent No. 2,403,961, issued July 16, 1946, and it particularly has for its object to provide a novel method of manufacturing the needle and certain improvements in the structure of the needle which permits manufacture by the method hereinafter disclosed.

A further object is to so improve the structure of the needle that all danger of the needle and needle tongue catching on the thread guides as the needles pass between the guides, or the guides pass between the needles as the case may be.

In my application aforesaid the needle is grooved along the edge of the shank which is on the side of the-hook'and the tongue is made of a single thickness of metal. 'While this arrangement is generally satisfactory in needles of the coarser gages it is not entirely so with'very fine gage needles as, for example, in needles of 32 to the inch.

In order to positively provide against the needles and thread guides engaging edgewise I have now made the needle of a single thickness of metal and provided the tongue with sides or wings to go around the edge of the needle which is toward the hook and overlap the sides of the needle shank below the place where the thread would engage the edge of the needle in passing between the thread guides after racking.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends the invention also includes those novel details of construction, combination and arrangement of parts all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawing in which:

Fig. 1 is a side elevational view of the needle blank.

Fig. 2 is a view similar to Fig. 1 showing the hook bent in toward the shank in the second step of manufacture.

Fig. 3 is a side elevational view of the completed needle, the thread passage being shown normally open in full lines and closed in dotted lines.

7 Fig. 4 is a cross section on the line 44 of Fig. 3.

Fig. 5 is a cross section on the line 5-5 of Fig. 3.

Fig. 6 is a detail top plan view of the needle shown in Fig. 3.

Fig. 7 is a detail elevational view of the upper 'end of a tongue blank before folding.

Fig. 8 is a diagrammatic view illustrating the movement of the needle and tongue through be,- tween adjacent thread guides.

Fig. 9 is a diagrammatic view showing the path taken by the hook end of the needle with relation to stationary threadguides.

In the drawing in which like numerals of reference indicate like parts in all the figures, 1 represents the shank of the needle which needle. in the present invention, is stamped from a sheet or strip of steel with the beard 2 of the hook portion, diverging from the point end or top 4 of the hook portion toward the inturned point 3' of the beard, and provided with a heel or inward projection 5 adjacent the top which projection is spaced from the shank a distance of about the thicknessof the tongue portion Ill as shown in Fig. 1. After the blank has'been stamped out the heard 2 is bent toward the shank! until the heel 5 contacts the shank as shown in Fig. 2. This leaves an opening 6 into which the curled end ll of the tongue is later placed.

The tongue is also stamped from a piece of sheet steel in the form shown in Fig. 7. The width of the tongue blank is sharply reduced by tapering the sides of the blank as at 9 leaving the end portion ll] of the same width as the thickness of the needle, see Figs. 3 and 4. The tongue blank is stamped with a hole l2 to receive the point 3 of the beard 2 when the needle and tongue are assembled and the thread passage l8 into the hook end of the needle is closed by the tongue. The end ll of the blank portion I0 is curled over to fit the opening 6 and the sides 1 are bent over at right angles along the

lines

8, 8

in Fig. '7 to fit over the sides of the needle shank I, see Figs. 3 and 5.

After the needle blank has been stamped and the hook pressed together (Fig. 2), the needle is properly tempered. The tongue is also tempered, after which the two parts are ready to be assembled. In order to assemble the parts the beard 2 is sprung open far enough to permit the tongue loop to be inserted sidewise in the opening 6 and the part l0 to lie between the heel 5 and the shank l. The tapered sides 9 will permit this sidewise method of assembly after which the sides are released to embrace the needle shank as shown in full lines in Fig. 3. It should of course be understood that the sides 1 engage the sides of the needle shank with a sliding fit.

The needle shank is set in a lead base l3 in the usual manner and the tongue is similarly set in a lead base 14 as shown in Fig. 3.

By reference to Figs. 8 and 9 the movements 4. In a knitting machine needle having a shank and a hook end and a thread passage into the hook end, and having a thread-passagecloslng tongue anchored at one end within the hook, the

improvement which includes: a needle comprising a flat metal body including a shank and a hooken-d, the beard of-thehookhaving its point spaced from the shank to constitute a thread passage and a tongue having a longitudinally grooved .shank and an ungrooved portion anchored to the needle .at the hook end andlying within the hook the path I9 shown in Fig. 9, first straight up to 7 about the position shown in Fig. 3 and then to the right in the direction of the arrow .a'until it passes the eyes of the thread guides and then upwardly backwardly over the loop of the "P to the left of the thread guide-eyes and back down again to pick up the threads and pass down through the sinkers and the previously .iiormed.

1001) L of the knitting.

/ By-constructing the needle with the tongue as the outside member and leaving the sides of the tongue ed for a distance from the anchorage of the tongueindicated at an in Fig. '3), all danger of tangling. with the thread guides isavoided.

It will be noted by reference to the dotted line position in. Fig. 3 that whenthethread passage -in-tothe hookis closed, the freeedges of the sides "I willvnotproiect beyond the front (right hand) edge of the shank of the needle, and will thereioreinot'. present edges which might tend to cut theploop as the :hook is passed; through a loop or sas itiisbeingca st'ofi' the needle.
