KNITTING-MACHINE NEEDLE.

Application filed May 25, 1927.

My invent-ion relates more particularly to that class of knitting machine needles in which the latch and the hooked part of the needle are movable relatively to each other, and preferably the latch is asliding latch in guided sliding relation to the hooked part ot the needle, which draws the new loop.

The main object of my invention is to construct the needle so that the sliding latch will always close properly and facilitate the casting of the old loop.

In the accompanying drawings:

Fig. 1 is a side elevation to an enlarged scale of a knitting machine needle construct- 7 ed in accordance with my invention and adapted for use in circular or straight knitting machines;

Fig. 2 is a similar side view showing the sliding latch projected to the casting oil position;

Fig. 3 is a perspective view of the sliding latch;

i -i is an edge view of the closed latch,

ionding with Fig. 2;

F 5 is atransverse section on the line 5 of Fig. 1.

This takes the place of my application Ser. No. 636,082 filed May 2, 1923.

The hooked part- A01 thelneedle, which has at its outer end the usual hook a for taking the yarn and drawing the new loop may be o t any suitable construction and by pretercnce, it has at its rear end a suitable butt A by which the knitting cams may cause the necessary reciprocation of the needle.

On the side of the shank toward the hook of the needle is formed a longitudinal groove 10 adapted to receive and guide the toe 12 of the sliding latch 13. The outer end of this groove 10 is canimed out as indicated at 1 l. in Figs. 1 and 2, to cause the point 12 of the sliding latch B, when fully projected, to more outwardly to meet the point of the hook (I.

The rear end of this sliding latch may be n'ovided with a butt B to be operated by a cam or cams on the machine, or it may be actuated in any other convenient way.

I prefer to limit the longitudinal move ments of the latch B with relation to the needle part A by providing a projection 13 on the latch to contact with shoulders 14: and 15 on the part A at the extremities of the relative movements of the two parts of the needle.

Serial No. 194,223.

One of the most im iortant features of my invention consists in making the outer end of the point of the latch split through to embrace between those split ends the point of the hook a. As the best way to accomplish this I make the sliding latch of a pair or thin plates 16, 16, closely secured together by rivets 1'7, 17, or in any other suitable way, and I thin down the point 12 of the sliding latch at the side next the shank of the needle A as seen in Figs. 3 and 5, so that it may conveniently enter and be guided within the groove 10, as before explained. The parts of the two plates 16, 16 constituting the point oi the sliding latch are so constructed as to tend to spring apart slightly, as seen in Fig. 3, when they come out of the groove 10. Thus the split point of the latch is collapsible, or closes up, when drawn back into the groove in the shank of the needle and can consequently be then buried in that groove while on the other hand the split point of the sliding latch expands laterally when it is projected out of the groove to em brace and bury the point of the hook a. I also prefer to make the rear ends of the plates 16, 16, spring apart slightly so as to provide a frictional bearing against the side walls of the needle grooves of the cylinder, dial or frame of the machine, as the case may be.

The groove 10 in the shank of the part A is preferably deep enough to substantially cover the point 12 of the sliding latch B, when the latter is drawn back, as seen in Fig. 1. And this is preferably true for the full length of the groove so that when the instep needles in a hosiery knitting machine are projected to inoperative positions during the knitting of the heel and toe pockets, the points of the sliding latches B may be reciprocated within the loops on the shanks of the parts A without harm,

IVhat I claim is:

1. A knitting machine needle having a hooked part with a grooved shank, in com bination with a relatively movable latch having an end split-through permitting the two sides of the end to yield and embrace the point of the hook when projected, said end being adapted to slide in the groove of the shank.

2. A knitting machine needle having a. hooked part, in combination with a relatively movable latch having an end splitthrough permitting the point of the latch to expand laterally and embrace the point of the hook when the latch is projected.

3. A knitting machine needle having a p hooked part with a grooved shank, in combination with a sliding latch constructed of two plates closely secured together, the point of the latch being adapted to slide in the groove of the shank of thehooked part and to resiliently yield and embrace the point of the hook when projected.

4. A knitting machine needle having a hooked part with a grooved shank, in combination with a sliding latch constructed of two plates, the point of the latchbeing resilient and the two plates being adapted to yield laterally and embracethc point of the hook when thelatch .is projected, the side of the latch adjacent the shank being reduced in width to enter the grove in the shank.

A knitting machine needle having a hooked part, in combination with a sliding latch constructed of two plates riveted together with the forward and rear ends rcsilient said forward end being adapted to yield laterally and embrace the point of the hook when the latch is projected, as and for the purposes set forth.

6. A, knitting machine needle having a hooked part with a grooved shank, in com bination with a relatively movable latch having a resilient split-through end which when projected will yield and embrace the oint of the hook and when retracted will be wholly contained within the groove of the shank.

'Z. A knitting machine needle having a hooked part with a grooved shank cammed out at the outer-end, in combination with a relatively movable latch having a resilient split-through end which when projected will belcalnmed outwardly and yield and cmbrace the point of the hook and when retracted will be wholly contained within the groove of the shank.

8; A knitting machine needle having a hooked part with a grooved shank, in combination with a sliding latch constructed of two plates riveted together, the parts of the two plates forming the point of the latch being adapted upon retraction to be compressed within and to be covered by the groove in the shank but adapted when projected to be pushed upwardly toward'the point of the hook, to expand laterally and to embrace the point of the hook, substantially as described.

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

ALBERT E. PAGE.
