Filed July 3, 1929 I v gvwentoz Patented May 20, 1930 UNITED STATES PATENT OFFICE ALEXANDER C. PARLINI, OF WOODSIDE, NEW YORK, ASSIGNOR TO GOTHAMI IKN'I'IIBAC 'IACHINE CORPORATION, OF NEW YORK, Y., A CORPORATION OF DELAWARE imrrr'mo NEEDLE Application filed July 3, 1928. Serial No. 875,658.

This invention relates to knittin needles adapted to be manipulated by han or in a machine for repairing runs in knitted fabrics such as hoisery, and more particularly relates tothe latch construction of such a type of needle.

One of the great difficulties encountered with knitting needles used for'the repairing ofruns in fabric has been the failure of the latch member to remain in its retracted or open position when thrown upwardly by a thread of the run being repaired, a suflicient length of time so as not to interfere with the engagement of the hook of the needle with the next cross thread of the run. In needles heretofore constructed there is a tendency for the latch to jar out of, or become displaced from itsretracted position prematurely and thus prevent the proper or rapid operation of the needle.

It is the object of the present invention to provide a construction of latch member which will frictionally retain itself in open position, or in fact, in any position it is moved, with respect to the shank, by a thread of the run being repaired.

Further objects of the invention will appear more fully hereinafter.

The invention resides substantially in the structure hereinafter described, as illustrated in the accompanying drawings, and pointed out in the appended claims.

Referring to the drawings:

Figure 1 is a front elevation of a needle constructed in accordance with my invention showing the latch member in closed position.

Fig. 2 is a view in side elevation of the needle also showing the latch member in closed position.

Fig. 3 is a viewin transverse section taken on the line 33 of Fig. 2 looking in the direction of the arrows.

Fi 4 is a top plan view of the latch mem er.

Fig. 5 is a side view of said latch member.

The needle comprises a shank portion 1 which terminates in the hook 2. If the needle is operated by hand the shank is secured to a suitable handle (not shown) so that it can u be more readily operated. In case the needle is used in a run repairingmachine the shank is secured in the usual manner to the needle bar thereof.

The shank is provided wit-h a slot 3 which 1ios adlapted to pivotally receive the latch mem- The latch member comprises a resilient piece of metal which is slit into two fins 5 and 6 and is formed with a hood ortion 7 adapted to contact with the point 0 the hook portion 2. A hole 8 is provided in each of the fins 5 and 6 which is adapted to receive the pivot pin 9 secured in the shank.

The fins 5 and 6 of the latch member are separated from each other sufiiciently so that a slight pressure is necessary to bring their faces together and when such pressure is released they will have a tendency to spring away from each other.

In assembling the latch member with the needle shank the resilient fin portions 5 and 6 thereof are pressed together so as to fit in the slotted portion of the shank and the pivot pin inserted through the hole 8 thereof.

When the pressure is released from the fins the flat side faces of the fins spring'into frictional engagement with the inner side faces of the slot 3.

It will be seen that due to the frictional pressure exerted by the faces of the fins against the inner faces of the slot that the latch member will tend to stay in any position it is moved around the axis of the pivot pin 9 and will retain this position until forced therefrom by the action of a thread of the run being repaired.

By such a construction of the latch member there is no liability of the latch dropping to closed position or partially closed position prematurely and it is necessary in order to change the position of the latch to force the same manually or by means of a thread to a new position.

Having now described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. A run repair needle having a hook portion and a slotted shank portion with a pivot pin in said shank portion, in combination with a latch member having a hood to protect said hook and resilient fins' extending from said hood to said Fivot pin tofrictlonally engage the sides 0 said slot.

2. A run repair needle having a hook portion and a slotted shank ortion with a p1vot pin in said shank portion, in combination with a latch member comprisin a hooded body part and divergin fin mem ers to frictionally engage the si es of the slot about said pivot pin.

3. A latch member for run repair needles having a slotted shank, said latch member comfigrising a head having a cavity and a pair of s diverging from said head, said fins resiliently engagmg the walls of said slotted shank.

4. A latch member for run repair needles comprising a hood like head and two diverging fins extendinghtherefrom.
