KNITTING-NEEDLE.

Application filed October 2, 1919.

['0 (I? Z in 720m it may concern:

Be it known that 1, Bar .FENN, a citizen of the llnited States. and a residentof Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Knitting-Needles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to knitting needles and more particularly to knitting needles having relatively slidable hook and casting-off members as distinguished from needles having latches or spring beards.

"he invention consists in the combinaof parts set forth in the following specification and particularly pointed out in the claims.

In the drawings wherein I have shown merely for illustrative purposes one embodiment of the invention- Figure 1 is an enlarged side elevation of the knitting needle;

Fig. 2 is an enlarged perspective the hooked member of the needle;

view of Fig. 3 is an enlarged detail perspective I view of the casting-off member thereof;

Fig. 4 is a transverse section taken on the line =i-4. of Fig. 1;

Fig. 5 is a transverse section taken on the line 5-5 of Fig. 1;

Fig. 6 is a very much enlarged longitudinal section of the loop forming end of the needle;

Fig. 7 is a diagram illustrating the first step in the formation of 'a loop;

Fig. 8 is a view similar to Fig.7 illustrating another step in the formation of a loop and Fig; 9 is similar to Figs. 7 and 8 illustrating the completion of the formation of a loop upon the needle embodying this invention.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 1 indicates one member of the needle which for purposes of identification is termed a hooked member having a hook 2 formed at one end thereof.

3 indicates another part of said needle which for convenience has been designated a sheath, and this sheath preferably has a groove 4 formed in the back edge thereof to receive the stem 1 of the hooked mem- Specification of Letters Patent.

her 1 and permit a relative longitudinal movement between said hooked member and said sheath. The sheath 3 may be and is herein shown formed from sheet metal bent substantially U-shaped or in channel formation as will be seen most clearly in Fig. 5, so as to engage the front edge and opposite sides of the stem of said hooked member 1; the term .front edge herein designating that edge of the needle that is directed toward the open end of the groove of the needle cylinder or that edge from which the hook of the needle projects.

Furthermore the sheath 3 constitutes what has been called the casting-off member of the knitting needle and which I alSO designate as the hook guarding member and in order to render said sheath capable of effecting the casting-0H of loops a suitably formed loop guiding element, herein the finger 5, is provided at one end thereof to cooperate hook 2 of said hooked member. The finger 5 is outwardly or laterally curved with respect to the body of the sheath 3 as at 5 and its front edge or face which is extended slightly beyond the end 7 of the hook 2 may, if desired, be recessed as shown at 6 to receive said end 7 at certain times in the loop forming operations in order to cover said end so that the old loop upon the needle shank may be properly cast off over the new yarn held within the hook of the needle as hereinafter more fully described.

The end of the finger 5 is bent backward at an angle to the portion 5 and is herein formed to extend into the hook 2, of the needle and means are provided for guiding the extremity of said finger during relative longitudinal movements of said hooked memher and said sheath, said means including a groove 8 formed in the front edge or hook side of the stem of said hooked member 1 preferably in a thickened portion 9 thereof. In order to facilitate cooperation with said slot the tip end of the finger 5 is herein flattened as at 10, (see Fig. 4), that is the opposite edges of the U-shaped portion are pressed together so as to fit into said groove 8 and thus properly guide said finger during its loop forming operations.

During the formation of loops by the needle embodying this invention said needle may be and preferably is reciprocated in the usual manner, that is if knitting is to be produced by hand, said needle will be moved longitudinally by hand, or if the needle is to be used as a machine needle then the reciprocating thereof will be effected by the usual knitting cams and in the present example I have illustrated a. needle constructed to be used in a knitting machine and to be functioned in the usual manner by knitting cams. Therefore the needle is provided with a knitting butt 11 formed in the usual manner and herein projecting from the front edge of the hooked member. During the reciprocation of said hooked member by the knitting cams to form loops of the fabric it is desirable that the sheath 3 be retarded in its longitudinal movement so as to create a relative movement between said sheath and said hooked member, thus movingthe loop-forming finger 5 toward andaway from the end of the hook 7.

For the purpose of retarding the movements of said sheath I have herein provided an enlargement 12 at a suitable point upon said sheath preferably at the front portion thereof, as shown and in such a location. as to engage, (hiring certain portions of the reciprocating movement of the needle, the

usual spring band or bands. 13 of the knitting machine within which the needle is arranged (see Fig. 1).

Itis also desirable toprovide means for limiting the relative longitudinal. movements of said hooked member and. said sheath and for this purpose I have herein provided means including a slot 14 formed in the front wall of the sheath 3 near the lower end thereof and through which is arranged to extend the knitting butt 11, said slot being of a length sufficient to permit the finger 5 of said sheath to move away from the end 7 of the hook of the needle in order to allow new yarn to be inserted between said finger and said book, while in the opposite direction said slot is made sufficiently long to allow the tip 7 of said hook to enter the'recess or notch 6 of said finger.

The design of the stem of the hooked member 1 of the needle may within the scope and purpose of the invention be varied as desired and likewise the design of the sheath may be altered to conform to a greater or less degree with that of the hooked member. It is, however, desirable that the walls of the sheath be as thin as possible in order that the combined hooked member and sheath below the finger 5 and also at the finger 5 will not cause the loops that are being formed thereon to be unnecessarily enlarged, in fact these loops need upon the usual latch needle.

It is furthermorewithin the scope and purpose of the invention to form said sheath in any esired manner, the present example which preferably involves the stamping of the same from sheet metal to substantially be no larger,'if as large as those formed correspond with the shape of the stem of the hooked member, being but one of the many methods that may be followed in this respect.

-In Figs. 7, 8 and 9 are illustrated three the construction of the particular type of fabric shown. v p

In Fig. 7 the hook 2 is shown in itshighest position withnew yarn 15 laid around the front portion of the stem 1 directly beneath the end 7 of said hook, while the finger 5 is illustrated-in its lowermost position with respect to said hook and the old loop previously formed upon the needle is shown at 16 below the curved finger 5 of said sheath. The hooked member'is raised to the position shown herein by the usual knitting cams engaging the knitting butt 11 and during the upward movement of said hooked member a similar upward movement of the sheath 3 is prevented, or retarded at least, by reason of the enlargement 12 engaging the spring bands 13 of the knitting machine which are gener ally disposed in circumferential grooves formed in the outer face of the needle cylinder. The extent of the movement of the sheath in a downward dil ectionis in the present example sufiicient only to separate the finger 5 thereof from the extremity 7 of thehook to allow for the admission of the new ya'rn 15 as shown in Fig. 7, but obviously this movement may, within the scope and purpose of this invention, be varied as desired by lengthening 0r shortening the slot 14.

The next step in the formation of a loop is shown in Fig. 8 wherein the hooked member has been depressed far enough for the extremity 7 of the hook thereof to enter the recess 6 of the casting-off member or loop forming finger and upon continued downward movement of the needle to the position shown in Fig. 9 the casting-off of the old loops 16 will be effected in the usual manner to form a new loop 17 from the new yarn 15 held within the hook 2 of the needle.

' lVhile I have herein shown and described merely for illustrative purposes oneyspecific embodiment of my invention. and have disclosed and discussed in detail the construction and arrangement incidental to such disclosure, it is to be distinctly understood that the invention is limited neither to the mere details or relative arrangement of the parts nor to the specific application herein shown, but that extensive variations from the illustrations may be made without departing from the principles thereof.
