TWISTING-MACHINE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed August 21, 1905. Serial No. 274,990.

To all whom it may concern:

Be it known that I, JASPER L. Saonn'r'r,

a citizen of the United States, residing at 1 to be used in twisting various materials intostring form, or 111 enveloping strings of any stance.

The object of my invention is to produce a machine of simple construction, by means of which any material, fibrous or metallic, may be twisted into string form, or by the use of which a string or cord may be enveloped in a covering of metallic or other material.

My machine is particularly designed for use in the manufacturing of my packing, as shown in an application heretofore filed by me in the Patent Ofiice, on May 19, 1905, Serial Number 26l,109, upon which Letters Patent No. 86%,996 were issued September 3, 1907, and in that connection serves to cover the flanor fibrous thread with a metallic covering by twisting the two together. Although especially made for such use, it may be employed for other purposes.

The following isa clear description of my invention, reference being made to the accoi'n'panying drawings, in which,

Figure 1 is a view in perspective of my invention, Fig. is a side elevation of my invention, Fig. 3 is another side elevation of the same. Fig. 4 is an end view of the same, and Fig. 0 is a vertical longitudinal sectional view of a portion of the same.

Similar numbers refer to similar parts throughout the several views.

Briefly, my invention comprises 'a rotatable shaft mounted on a standard or in suit able bearings, and provided with an arm carrying a drum and means whereby the drum is turned when the shaft is rotated.

Referring to the drawings, 1 represents a standard of ordinary construction, having a head-portion 2 on which is mounted, in suitable bearings, a shaft 4, held by a topplate 5 secured to the head-portion 2 by bolts (3, (3. For the purpose of lubricatingthe shaft 4, an oil-cup 7 is mounted on the top plate 5. The shaft 4: is bored longitudinally,

v i 4 l l i the boring 8 being of a diameter suflicient to accommodate the cord or string made or covered by the machine, and at one end the shaft is provided with a driving pulley l0, driven by belt 11, or in any other suitable way. Upon the other end of said shaft 4, is mounted a. collar or sleeve 16, and a transverse arm 20, said arm being held in place on said shaft by the loclonut 2t and washer and all said members being fixed to and v a rotating with said shaft. 1L fixed pulley 1? material in a covering of metal or other sub- 1 Both said fixed pulley and the end of saidv arm are provided with a central opening or boring, through which passes the shaft at and the collar 16, but said pulley 1? is secured to the arm 18 and is not affected by the rotation of the shaft 4 and collar 16.

The winding mechanism is carried upon a winding arm 25, extending parallel to the shaft 4 from one end of the transverse arm 20 and fixed thereto, and consists of a gearpulley 26, fixedly mounted on a rotatable arbor or pin 27 at the free end of the arm 25, and a drum 28 also fixedly mounted on a similar pin or arbor 29, situated about midway on the opposite side of said arm 25. The pin 27 extends through the arm 25, and has attached to that end a small gear 35, which enmeshcs with a large gear 37, mounted on and secured to the pin or arbor 29 between the drum 28 and the winding arm 25, the relative sizes of the two gears being such that it requires several revolutions of the gear-pulley 2G to turn the drum 28 one complete revolution, the turning of said drum being regulated entirely by the revolution of the. gear-pulley and gears. As the drum 28 is used to receive the finished product, it is so adjusted that the boring 8 in the shaft, if continued, would be tangent to its periphery as shown in Fig. 4c, and for this purpose the arbors or

pins

27 and 29 are mounted diagonally as respects the arm 20.

In onder to turnthe gear-pulley 26 when the machine is in operation. the periphery of said pulley is provided with a groove 40, in which travels an endless belt 42 connecting the gear-pulley to the fixed-pulley 17. the direction of said belt being changed by idlers A and 45.

For the purpose of steadying the machine by eradicating, as far as possible, vibration 11.v

I ous materia-ls'are twisted in stringform-,bnt v g operation. The twisting movement of the machine causes the metaltobetwisted around the string, enveloping. itgentirely material to be twisted together in'such man- .,ner' that the outside presents alternate f above stated, the'machine' is primarily em auism, I mount on the other end of said arm,

arm 20 around and causesfthe windingmechto pass throu the center. As the windingjmechanismconthis result a metal ribbon, V-sha-ped in cross wi'thi nthegroove in the' metal ribbon and due to the revolutions of the arm 20, which is weighted at one end by the winding mecha counterweight 50.

The operation of my machine is as follows. The ends of the materials to be twisted together are carried through the boring 8 and attached to the drum 28. The operator then stands on the other side of the machine and holds the materials as illus. trated in Fig. l, and the operation of the machine twists the materials into string form and at the same time winds the finished product upon the druni 28 which. when full, may be-' removed and an empty drum substitutedtherefor. The twisting of the materials is accomplished through the rotation of the shaft 4', which carries the p h a circular-orbit, of which theboring' 8'1f continued would be' 'tinues .to revolve through its. orbit, thel e'ndless belt'i42 being held on the, pulley 17 causesz a rotarymovement of thegean pul ley 2 6"""nd through the

gears

35 and 37. of the. Thewi-nding of the drum is 'r lated- ;by the relative sizes of-thesaitl gears and-false by the size of the'fixed pulley," as the belt-travels in each complete-revolution of thezflshaft' l' a difiance'j'equal to the-i grooved circumference'of the'fixed pulleys In the-ordinary use of my machine variit is als'ocapable of'being used for'envelope ing fibrous strings iii-metal. To accomplish 'sect1on,--and a string of any'fibrous' mate'-' rial are employed, the. string being laid;

held bythe operator while the machineis and does not" cause the metalv and fibrous" strands of metal and fibrous material. As-

ployed for this purpose n order to produce metallic coi'ered strands as shown in .1

and means for turning said pulley when said shaft is rotated. I

2. In a twisting machine, the combination of a shaft, an arm secured to said shaft, a drum or reel mounted on said arm and-provided with a gear, provided with a gear which meshes with the car on said reel or drum, and flexible means or turning said pulley when said shaft is rotated. A

whereby said pulley is turned when the sha isr'otated' .7 '4. In aftwisting machine, the-combination of a' shaft, an armmounted on said shaft, 'a-drum-rotatably mounted on said arm and a pulley on said armprovided with a gear, a pulley rotatably mountedfbn said arm andhavi a gear en- 'Ineshing with the gea'r on said rum, a stationary pulley and abelt running upon said pulley and 'said stationary pulley. l
