HAND-OPERATED LATCH NEEDLE.

Application med July so,

eration.

A further object is to provide a hand-operated latch'needle in which means is provided, for releasing the latch in the event that the latch should become locked, thereby insuring accurac in operation;

Other objects an advantages will'appear in the following specification, and the novelfeatures of the invention will be particularly pointed out in the appended claims. 7

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a perspective view of my-device,

in Figure 1,

Figure 3 is -an elevation of the device shown in Figure 2 turned 90, and

Figure 4 is a view showing an application of the device. r

In carrying out my invention, I make use of a handle 1 of any suitable shape adapted to support a needle 2 bent to form a stop 3. The needle 2 is provided with a hooked portion 4 anda latch 5 hinged at 6.

A flexible spring member is secured to the handle 1 and is bent double at 8 to provide a slotted member 9. The needle 2 passes through the slot and the member 9 is adapted to be moved relative to the needle from the full line position into the dotted line position shown in Figure 3. Movement-of the member 9 is limited by reason of the stop 3. During the operation of the device, that 1s,

when. the needle is passed through the fab ric, a thread will pass between thelatch 5 and the hooked portion 4; moving the latch 5 into the position shown in Figure 2. At this time, the slotted member 9 will be moved in contact with the stop 3. The slotted memher 9 acts as a guide for the device when the Figure 2 is an elevation of thedevice shown 1928. Serial No. 296,347.

latch 5 is in the position shown in Figure 2 a space 10 is provided between the latch and the slotted member 9. The space is such that a thread may be moved therein and between the latch and the needle 2. When the needle has been passed through the fabric and is removed therefrom, the spring-pressed member 9 will of course move back to its original position. It will be seen from Figure 2 that should the latch 5 become locked or bind, the member 9 will dislodge the latch, thereby insuring the operation of the device.

It will thus be seen that I have provided a needle which is easy to manipulate in that a guide 9 is provided. l/Vith this provision, a hand-operated needle may be operated rapidly and with a maximum degree of certainty.

While I have stated that the spring member 7 is secured to the handle 1, the spring "member 7 is preferably soldered to the needle I or secured thereto by other desirable means,

and associated with the needle for limiting the movement of the needle when the latter is passed through a fabric.

2. A hand-operated latch needle comprising a handle portion, a latch needle secured to the handle, and flexible means secured to the handle and disposed in operative relation with respect to the needle and adapted to be flexed by contact with a fabric for guiding and limiting the movement of the needle when the latter is projected through the fabric. 1 i

3. A hand-operated latch needle comprising a handle, alatch needle secured to the handle, spring means secured to the handle and disposed in operative relation with respect to the needle and adapted to be flexed when moved into engagement with a fabric for guiding and limiting the movement of the latter when the needle is projected through the fabric, and means secured to the handle for stopping the movement of said spring means.

4. A hand-operated latch needle comprising a handle, a needle secured to the handle, and spring means secured to the handle and disposed in operative relation with respect to-the needle and adapted to be moved by contacting with a fabric for limiting the movement of said needle when the latter is projeo'ted through the fabric, said needle being provided with a stop for limiting the movement of said spring means, said needle being provided with e latch adapted to be moved for bringing one end of said latch relatively near a portion of said spring means, whereby said spring means is adapted to move said latch in the direction of its original position when said latch needle is removed from the fabric.

Signed at Chicago, in the-county of Cook and State of Illinois this 25th day of July,

A Di. 1928.
