Yi, ASSIGN ORS, BY MESNE ASSIGNMENTS, TO GOTHAIE KNITBAC MACHINE COREGR-ATION. OFTJEW' YORK, N. 'Y., A CORPORATION OF DELAWARE KNITTING NEEDLE Application filed August 14, 1938. Serial no. 299,487.

This invention relates in general to the form of knitting needles adapted for use in our machine for repairing runs in fabrics of the type described in our co-pending application, Serial No. 248,806, filed January 28, 1928, patented April 9, 1929 as No. 1,708,675.

This invention relates particularly to improvements in knitting needles of the form disclosed in our co-pending application, Serial No. 293,430, filed July 17, 1928.

This invention relates particularly to the form of construction of the hook of the needle as disclosed in our co-pending case No. 293, 430 mentioned above.

The form of hook construction employed is termed the fish hook form in view of its similarity to a fish hook.

Another object of this invention is the construction of a knitting needle of the above type for use in the machine disclosed in our first mentioned application by means of which runs in fabrics may be rapidly and quickly repaired without the danger of skipping threads and as a result leaving undesired marks or holes in the repaired fabric.

These and other objects as will appear from the following disclosure are secured by means of this invention.

This invention resides substantially in the combination, construction, arrangement and relative location of parts all as will appear more fully hereinafter.

Figure 1 is a vertical cross sectional view through one form of needle having an off set portion running into the fish hook formed end.

Fig. 2 is a side elevational view of a modified form employing a straight shank. Fig. 3 is a front elevational view of the form of needle shown in Fig. 2.

It has been found in practice that while a knitting needle for use in the machine described in our co-pending application will do acceptable and commercial work, the form of needle disclosed herein where the ends form similar to a fish hook has also been found to give good practical results.

By means of this form of hook construction the hook readily passes between the threads which cross the run one at a time 'without danger of skipping or striking the cross threads. v vReferring to the drawings the needle is shown in F ig.-1 having a straight shank por tion 1 connected to the inclined portion 2 which extends at an angle with respect to the straight portion. The lower end of the inclined portion 2 runs into a curved portion 3 which is in the formof a fish hook so to speak. The curved portion 3 which forms a smooth surface running into the straight inclined portion 2 terminates in a barbed portion 4 which is straight as shown in the figures. The inclined portion 2 is provided with a slotted projection or hump 5 in which is pivotally mounted a latch member 6 having a widened portion to form a cam 7. A spring 8 is attached to the shank and its free end lies in the space-between the slotted portion 5 and presses against the cam 7. The

spring 8 is positioned so as to engage the cam shaped portion 7 of the latch member and to normally hold the. latch member under a slight tension in open position as illustrated in Fig. 1.

The form of needle shown in Fig. 2 only differs from that in Fig. 1 in that the shank portion 9 is straight throughout its length until it runs into the curved portion 10 which curved portion together with the straight part 11 forms a hook somewhat similar to a fish hook in shape. As before, the shank is provided with two parallel projections spaced apart to form the slot 14 in which is pivotally mounted a latch member 12 having the cam 13 on the end thereof. The cam 13 engages a spring 15 secured to the shank and having its free end extending into the slot and engaging the cam 13 of latch 12.

Fig. 3 is a front elevational view of the knitting needle shown in Fig. 2.

We will not attempt in this application to describe in detail the use of these needles since this has been done very carefully in our co-pending applications referred to above, and we areonly interested in particular, in the form of hook shown at the end of the needle. I

We are of course, well aware, that some changes in the details of construction and relative arrangement of parts as Well. as their proportion Will Occur to those skilled in the art and We do not therefore desire to be particularly limited to What We have shown for the purposes of illustration but to the scope of the appended claim.

What We seek to secure by United States Letters Patent is:

A knitting needle of the type described comprising a strai ht shank portion and a straight line portion inclined at an angle to said straight shank portion, a curved portion running abruptly into said straight line portion, and a latch member pivotally supported on the straight line portion of the needle, said latch portion being of such length as to just overlie the end of the hook portion when closed and reaching to the angle on the straight line portion When the latch is open. 7

In testimony whereof We have hereunto set our hands on this 8th day of August,

SAMUEL B. LEAVIN. WILLIAM H. LEAVIN.
