EDWA HD STICKLER, OF .lQNALASKA, WISCONSIN.

TWISTINQMCHINE.

T0 all whom it may Concern.: Be it known that I, Emmen STICKL'ER, a

citizen of the United States. .esiding at Onalaska', in the county of la Crosse and State of Wisconsin, have invent ed a new and use ful Twisting-Machine, of which the following isa specification.

This invention relates to means for tvsting- Tarn, twine, cord, rope and the like.

The principal object is lo provide :novel means of a simple nature, wherein the winding and twisting means are operated'in-such a manner that spools. bobbins or other holders lill, their speed will be automatically and properly varied with respect to the twisting means so as to avoid all drag, insure the same tension upon the material to be twisted and thus insure the same twist throughout the entire length, thereby securing a uniform product. A

Another' and important object is to provide novel means, whereby when the spools or holders are filled, the machine will beaufomatically stopped, thereby preventing' overwinding and permitting the removal of the filled holders and the introduction of the em )ty ones.

i still further object is to provide simple and novel means for insuring the proper operation of the twisting devices, avoiding any danger of their slipping and to provide tension mechanism for the strands, that is readily adjustable to secure the proper resistance and to avoid too free feed, to provide mechanism that can he stopped at any time when it is .found convenient or necessary, andto provide mechanism whereby the twist of the yarn can be varied as desired.

The preferred form of construction is illustrated in the accompanying drawings, wherein:- v

Figure 1 is a front elevation of the machine. Fig. 2 rs a rear elevation o f the machine. Figi3 isla side elevation thereof. top planview. Fig. 5 is a detail perspective glie/w of tihe autoi'natic stopping mechanism.

ends of the bars 8 are provided with notches 10 that receive guide rods 11 secured to the frame. Upon the reciprocatory frame are journaled a plurality of winding devices, consisting of upright spindles 12 that reject above the upper bar 8 to receive s oo other holders for the com lete` material. These spindles 12 are provided between the bars S of the reci )r'ocatory frame with pulleys 14, around which pass belts 15 that also `ass around a. drum 16, carried by a secon ary drive shaft 17', journaled in the frame and projecting beyond the opposite sides thereof. Journaled in a pair of s aced bars 7*l of the main frame 7 are a plura ity of twisting devices or fliers that are associated with the winding means above described, and comprise spaced depending arms 18 carried .b upright tubular shafts 19, the arms of eac flier bein located on opposite sides of one of the spind es 12 and having eyes 20 formed at their lower ends. The tubular shafts 19 of the'iliers are provided between the bars 7 with oblique toothed gears 21, and meshin with these gears are larger obli ue toothe gears 22 carried by a horizonta y disposed main driving,r sha-ft 23 that is alsojournaled in the main frame 7, and rejects beyond the opposite sides thereof. 'lphe main drive shaft 23 is designed to be operated from any suitable souree of. ower, transmitted by a belt (not shown), w lich operates upon loose and tight pulleys 24 and 25 mounted on one of the projecting ends of the shaft 23. The power imparted to the drive shaft 23 is transmitted to the-secondary shaft 17, through the medium of a' crossed belt 26 that operates upon oppositely disposed cone pulleys 27 secured to the shafts 17 and 23 on the opposite side of the machine to the loose and tight.

pulleys 24 and 25.

The reciprocatory movement of the carrier fra-me 8-9 is secured hy the following mechanism. A shaft 28, journaled on the main frame, is provided with a pair of heartshaped cams 29- that operate against the inner ends of a pair of levers 30, said levers being fulcrumer as shown at 31 between their ends. The outer ends of the levers rest against the under side of the reciprocatory frame. One end of the shaft 28 carries a worm wheel 32, and meshing therewith is a worm 33 carried by a countershaft 34 journaled on one side of the frame and having a worm wheel 35 on its rear end. A worm 36, carried by the secondary shaft 17 cooperates able movements of the winding and. twisting devices, the following mechanism is employed. A reciprocatory rod 37 is mounted in the supportin frame 7, and carries at one end, a yoke 38 t at engages the crossed belt 26. The rod 37 is held against rotation by ar screw 39 mounted in the supporting frame fscrew and engaging in a slot 40 in said rod. Upon the rod is loosely journaled a s iral cam 41,

yand operating against the spira face of said cam, is arm-42 fixed to the rod 37 by a set A spring 44, surrounding a portion of the rod, has one end secured thereto,

' as shown at 45, while its other end is fastened to a hanger 'bracket 46, depending from the su orting frame. This spring serves to hold) the inner end of the arm 42 against the spiral face of the cam, and yet permits the outward movement `ot' the rod, as will be apparent. Fulcrumed between its ends on one side of the frame,.is a lever 47. The rear end of this lever carries a dog 48 cooperating with a'ratchet wheel 49, connected to the spiralv cam. 41. A loose do 50 engages the ratchet wheel and prevents the retrograde movement of the same, and consequently of the cam. The front end of the lever 47 is located above and in the path of movement of the carrier frame 8 9 so that when ysaid carrier frame is moved upwardly, the' front end of the lever will be moved in a corresponding direction, and the dog 48 will ride loosel over one or more teeth of the ratchet whee 49. The return movement of the lever 47 is secured by means of a weight 51, adj ustably mounted on the front arm of the lever 47, and it will be evident that upon the downward movement of the lever, the dog will interlock with the teeth of the ratchet wheel 49 and effect a par-s tial rotation of vsaid wheel. The downward movement of the lever is stopped by an adjustable screw 52, adjustably carried by the frame and having its upperend disposed in the path of movement of the front end of the lever.

Associated. with the loose and tight pulleys 24 and 25 is a belt shiftimr "oke 53, carried by a horizontally disposed bell crank lever 54 pivoted shown at 55 to the` top of the machine. '.llie outward movement of this lever is limited by a stop spring 56 secured to the top of the machine and having a downset portion 57 that frietionally engages said lever to hold itin a predetermined position. The bell crank lever 54, and consequently'the belt shifting yoke 53 is moved by a'crank arm 58, the upper end of which is loosely engaged in an openingr in the lever 54, the lower end being iixe'l to 'a rock shaft 59, journaled on the adjacent side of the machine. This rock shaft has another .upstanding crank arm 6() the upper end of which is disposed inthe path of movement of a reciprocatory plunger rod 61, slidably mounted on the rear upper end of the machine. A coiled spring 62 urges said rod outwardly7 but it is normally held against outward movement by a sliding and swinging latch 63, the upper offset end 64 ofwhich engages in a notch 65, formed in the rear side of the rod, said rod having an upwardly inclined portion 66 disf posed ,directly in rear of the notch. The lower end of the latch 63 extends between a pair of guides 67, and is disposedin the path fof movement of a pin or projection 68, iixed tothe inner side of the ratchet wheel 49. A spring 69 bears against the upper end of the latch 63I to hold 1t. in the note 1 65. An actuating handle 70 is referably secured to the front end of the roc shaft 59, and affords convenient means, whereby the belt can be manually shifted from the loose to the tight pulley or vice versa. l Y

The Ymaterial to be twisted and wound, is preferably mounted on spools or spindles 71 that are journaled on upstanding stems 72, which stems are mounted in a carrier frame 7 3 fastened upon the to of the machine. Between this holder and t 1e twisting devices or fliers,- is a tension frame, the same consisting of spaced rods 7 4`eonnecte'd at their ends to cross bars 75. The frame thus formed, is rotatably 'mounted in a pair of standards 76 secured to the top of the frame, and is normally held against rotation, and in dillerent fixed positions by nuts 77 that bear against the Iupper ends of the standards.

The o eration of the machine may be briefly r escribed as follows. When the winding and twisting operations are first started', the caln 41 is so arranged'that the arm 42 bears against its innermost end, and

ios.

consequently the belt 26 will be upoirthe inner ends of the cone pulleys 27. lf n ow, the shifter 53 is moved by the handle 70, so that the belt will be upon the tight pulley 25, it will be evident that the various mechanisms will be thrown into operation, that is to say, the spools or holders will be rotated, and the fliers will also be rotated, thereby twisting the strands, as they come from the s iindles 72, and winding them upon the spools. At the same time, the carrier frame 8-9 will be reciprocated. 'lhis movement will cause the swinging of the lever 47, effecting a step-bystep rotation oi' the ratchet wheel 49, and 'the rotation of the cam 4l. As a result, the

belt 26 will be gradually moved toward the varying the relative rates of speed of the fliers, and winding devices. The yarn, cord, twine or other material is thus wound evenly from one end of each spoolto the other'and the v relative change of speeds insures the roper tension and uniform twist of the same. en the spools are iilled, 'the cam 41 has made one com lete revolution, and therefore the arm 42 wi l be 'forced back to the inner j@ end'of the spiral face. At the same time, the pin or projection will strike the `latch 63,

i swinging it so that its upper end will disongage from the notch 65, thereby releasing the rod or bar 61. 'The spring 62 will there y" fore force said 'rod or bar outwardly, swinging the crank arm 60, operating the rock s aft 59, swinging the crank arm 58, and thus shifting v'the belt back to the loose pulley.' At the same time, the latch 63 will be raised by the inclined ortion 66 of the rod or bar and said pin wil move beyond the same.

s o ols have been removed, and empty ones p aced in positionthe machine can be a ain started by merely throwing the belt shifter 53, so' that'the drivin belt will be moved on to the tight pulley, whereupon the operation will be repeated.4

` One of the important features of the invenf tion `relates to the means, whereby the mechanism maybe made to produce various kinds y' of twists, said mechanism being such that the ,twist of the yarn or other material can be varied from one turn, to two hundred turns,

`:i5 to the inch, depending upon the vfinish and character of the yarn or material. This is done by loosening the thumb screw'43 and adjustin the shifter rod 37 in one direction,

or the ot er, thus moving' the belt 26 on the 40' cones 27, so as to change the intakejof the yarn, or in other words, vary the speed of rotation of the winding devices with respect to the twisters. AnotherI very important feature is the positive spiral gear drives for the fliers. As is wellknown to those skilled in the art, bands are ordinarily used, and while bands may be employed in connection with the other features of this machine, the spiral caring` is advanta feous, particularly in eavy work, for bant s are liable to slip, and thus produce variable twists inthe yarn, but

by the Imechanism set forth, the twisting action is made positive. The frame 74-7 5 is also an important feature, for by means of it,

E5 the proper tensioncan be placed on the yarn passed through the same, and said frame constitutes very simple means for varying this tension.

From the foregoing, it isthougbt that the fr .constructiom operation, and many advantages ofthe herein described invention will out urther description, and it will be understood that various changes inthe size, shape, (E proportion, and minor details of construc- Ii." will ,thus be evident that after the filled beapparent to those skilled in the art, withf tion, may be resorted to without departing from the s irit or sacrificing any of the advantages o the invention.
