PATENT SPINNENG MACHINE.

SPECIFICATION forming part of Letters Patent No. 699,672, dated May 13, 192`.

Application filed May 29, 1901.

To @ZZ whom it may concern.:

Beit known that I, JOHN G. Fnnnnntcxs, a citizen of the United States, residing at Reading,in the county of Berks and State of Pennsylvania, have inventednew and useful Improvements in Spinning-Machines, vof which the following is a specification.

This invention relates to new and useful improvements in jenny-tubes for spinningmachines for producing twine, rope, yarn, &c., from flax, manila, hemp, and other hard fibers. Its primary object is to provide a device of simple construction whereby a thread of uniform size and strength is produced.

A further object is to employ dies for securing this result, said dies being provided with novel means for securing the desired pressure upon the fibers.

With these and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure lis a side elevation of the invention. Fig. 2 is a vertical longitudinal section therethrough. Figs. 3, 4, and 5 are detail views of the lower and upper dies, respectively.

Referring to the drawings by numerals of reference, 1 designates a base-plate, upon which is mounted a tube 2, having a pocket 3 in the top thereof. Seated within this pocket is a die 4, having a groove 5 extending longitudinally in the upper face thereof and in alinement with the passage 6, extending through the tube. A block 7 is secured in any suitable manner to the top of the tube and over the pocket therein, and extending from this block is a tube S, within which is slidably mounted a stem 9, which extends through the bloclt and is secured at its lower end to a second die '10, which is adapted to bear upon the die 4. This second die is also provided in its lower face with a longitudinally-extending groove 11, which registers with the groove 5 in theA die 4. The stem 9 is provided with a shoulder 12, and a coil-spring at opposite ends upon said shoulder and upon a bolt 14, which screws into the upper ends of the tube 8. This spring serves to hold the stem 9 normally projected downward. Slots 15 are ar- Serial No. 62,396- (No model.)

ranged in opposite sides of the tube 8, and

within these are slidably lnounted laterallyextending arms 16, which are formed with or secured to the stem 9 and serve to limit thc movement thereof within the tube.

A collar 17,is slidably mounted upon the tube 8 and is provided with an upper cam edge 18, which is adapted when turned in one direction to raise the arms 16. This cam, however, is normally in such position as to permit the arms to lie at their lowest positions. An arm, as 19, may be employed for turning the cam 18, and a suitable stop 2O may also be employed for limiting the movement of said cam.

A third die 21 is arranged in front of the die 10 and is provided in its lower face with a groove 22, which is in alinement with the groove 1l in die 10. This die 21 is provided with a stem 23, which is slidably mounted within the forward end of the block 7, and the die is held normally projected downward below the lower face of die 10 by means of a coil-spring 24, which bears at opposite ends upon said block 7 and the die 21,respectively. An arm 25 is adjustably secured by the stem 23 at a point above the block 7 and is contacted by the cam 17. This arm and its stem are adapted to be' raised in unison with thc arms 16 when the cam is turned.

Vhen the fibers are fed to the j enny-tube, they are passed between the dies 4 and 10, and the pressure of these dies thereon will produce a thread of uniform size and strength. The front die 21 normally extends below the die 10 and bears tightly upon the fiber and prevents the twist from passing through the tube.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware that modications may be made therein without departing from the spirit or sacrilicing any of the advantages thereof, and I-'therefore reserve the right to make all such changes as` fairly fall within the scope of the invention. Having thus fullydescribed my invention, what I claim as new, and desire to secure vby Letters Patent, is-

1. The combination with a tube having a pocket therein; of a grooved die seated within the tubo; a vertically-movable die theres above; a stem to said die; a spring inclosing the said stem and adapted to hold the dies normally in contact; arms to 'the stem; and a cam inclosing said stem and normally contacting with the arm, said cam being adapted to raise the stem and its die.

2. In a device Of the character described, the combination with a tube having a pocket therein, Of a grooved die seated Within the pocket, independent vertically-movable dies thereon, means for holding said dies normally in contact with the grooved die and means for raising the movable dies simultaneously.

3. In a device of the character described, the combination with atube having a pocket therein; of a grooved die seated Within the pocket, independent vertically movable grooved dies thereon, springs for holding said dies in contact with the die in the pocket,
