KNITTING-MACHINE NEEDLE AND LEVER FOR HOLDING SAME.

SPECIFICATION forming part of Letters Patent No. 781,654, dated February 7, 1905,

Application tiled June 2, 1904. Serial No. 210,806.

To It nrhmm it may concern:

Be it known that I, HARRY A. Housmmn, a citizen t the United States,residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Knitting-Machine Needles and Levers for Holding the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object certain improvements in knittiiig-machine needles and levers for holding the same, such as are shown and described in Letters Patent issued to me October 18, 1892, No. 464,737, in which each needle rests between the jaws of a lever, the needle being supported in line with the knitting-cams, but resting on a ledge extending around from the knitting-cams. By rocking a lever its needle is moved by contact with the jaw inward out of line of the knittingcams and is supported in that position by the end of the needle resting upon a ledge on the lever. In practice there is a tendency in moving these levers to throw these needles from operative position to inoperative position, and vice versa, and while in inoperative position for the needle to move upward, due to jar or otherwise, and thus releasing the loop from the latch, which is liable to close, and when again operated to miss a stitch, leaving a hole.

By my invention, as will hereinafter be fully described, I so construct the needle and lever that the needle is held from upward movement d uring the rocking ot' the lever and when in position to hold the needle in inoperative position.

I will tirst describe the embodiment of my invention illustrated in the accompanying drawings and then point out the invention in the claims.

In the drawings, Figure 1 is asectional view of needle, needle-lever embodying my invention, and a portion of cam-cylinder and portion of needle-ledge. Fig. 2 is a detail view of needle embodying my invention.

A is a portion of the cam-cylinder, and B the needle-ledge of the character and construction described and illustrated in my Patent No. ASL (37, be't'ore spoken of.

C is a lover of the general character described in said patent, pivoted at w and having the tailpiece C for tilting it. This lever, as in my previous patent, has the jaws c If, between which the shank/Z oi the needle I), having the butt 1/, the hook 1/ and pivoted latch 1/, projects. In Fig. I I have shown the lever tilted, with the needle moved so that the butt is oti the ledge B and the needle supported by the shank resting on ledge/l in lever-jaw c.

In my improved construction the needlelever jaw 0* is provided with a rectangular projection a and the needle with an inset w on the edge of its shank portion. \Vhen the lever is tilted to the position shown in Fig. 1, the projection w enters the inset I. and pushes the needles from oil the ledge into inoperative position. The projection and ledge also ooact in this movement and while the lever is in that position and in returning to operative position to hold the needle from moving upward.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

I. In a knitting-machine, in combination, a needle, a pivoted needle-lever in which said needle is loosely held and, by the movement of which, is adapted to be moved from operative to inoperative position, said needle being free to move vertically in the lever when in operative position, and means to hold the needle from upward movement during said movement of the lever from operative to inoperative position.

2. .In a knittii'ig-machine, in combination, a needle, a pivoted needlelever in which said needle is loosely held and, by the movement of which, is adaptedto be moved from operative to inoperative position and vice versa, and means to hold the needle from upward movement during said movements of the lever from operative to inoperative position and vice versa.

In combination,a needle and pivoted needle-lever in which said needle is held, the lever having a projection and the needle an inset normally out of contact and adapted to coact, in one position of the lever, to hold the needle from moving upward.

4. A jaw needle-lever having a lateral projection from the upper portion of one of the aws.

5. In combination, aneedle and pivoted needle-lever in which the needle is loosely held, the needle having an inset and the lever a projection, adapted, on the tilting of the lever to move the needle, to coact with the inset and hold the needle from vertical movement.

6. In combination, a needle and pivoted needle-lever in which said needle is held, the needle having an inset and the lever a projection, adapted, on the tilting of the lever to move the needle, to coact with the inset and hold the needle from vertical movement during said tilting and when in tilted position.

7. A needle having an inset in the edge of its shank portion.

8. A needle having a solid shank and an inset in the edge of said shank.

In testimony of which invention I have hereunto set my hand, at Philadelphia, on this 21st day of May, 1904;.
