l Patented Feb. 11, 190s.

Application filed January 18. 1907. Serial No. 352'851.

To all whom 'it may concern.'

Be it known that I, PAUL GUENTHER, a citizen of the United States, residing at Dover, Morris county, State of New Jersey,

have invented new and useful Improvements" thatone is accurately alined with the other.

This alinement is desirable, first, to prevent the inner -or lining thread from being eX- posed, and second, for preventing the outer or coveri with the od of the wearer, the threads being general y so selected, that While the outer thread appeals to the e e, the inner thread adds to the comforto the wearer.

By my invention the accurate alinement of the two threads is insured,` the alinement being princi ally produced by 'seatingthe outer threa within the sinker before the inner thread is carried linto juxta osition therewith Within such sinker. In t 's Way any intertwisting or other disarrangement of the threads ontheir way from the carriersl to the sinkers is prevented and a perfect product is insured.

The invention also comprises novel means lfor starting and stopping the carriers of the inner threads, while forming the two-pl sole flaps that Hank the top of openwor stockings and various other features of construction, hereinafter more fully pointed out. In the accom anying drawlngs: Figure 1 is a plan of the eft hand end of a straight knittlng machine embodying In Fig. 2 a plan of the right han end of the same; Fig. 3 a cross section4 through the machine; Fig.v 4 a front view of a needle-bar and coperating parts; Fig. 5 a plan of the left han head of the machine; Fig. 6 an end elevation artly in section thereof; Fig. 7 a cross section lon line 7 7, Fig. 5; Fig. 8 a cross section on line 8 8, Fi 5; Fig. 9 a

The drawings illustrate only thoseparts 0f a straight knitting machine of the Cotton type which are pertinent tol my invention, t e parts omitted being of Well known construction.

' The numeral 21 indicates the main frame of a knitting machine adapted to su port the shogg'ing-bar 22 and the shogging-s

afts

23, 24 and 25.

Parts

22, 23,24 and 25 are axi'- ally reciprocated by well known mechanism, (not shown). Shafts 23 andv 24 are connected to and reciprocate longitudinal main shogging bars 26, to which the

main thread carriers

27, 28 are secured in'the usual manner. Of these, carrier 28 is used onl for purposes foreign to this invention. haft 25 is adapted to reciprocate a lower longi tudinal auxiliary shogging bar 29 and an upper auxiliary shogging bar 3.0, both of which are supported in suitable bearin s 31.

Bars

29, 30 may be coupled to sha usual frictlon boxes 32 slidably secured' to such shaft and rovided with Ylevers or catches 33 ada te to engage corresponding notches 34 of t e bars.

To lower bar 29 are secured the hand lining or splicing thread carriers 35, while' to the u per bar 30 are secured the left hand lining tliread carriers 36. Carrier 35 is designed for lining or reinforcing the right hand sole-portion 37 of the stocking foot 38, While carrier 36 is designed for reinforcing the left hand sole-portion -39 thereof. After the foot has been knitted up to line 40, (Fig.

-20) the toe isknitted by rendering one of the

lining thread carriers

35, 36 inoperative,

ig. 14 'a rear view of the rightJ 25 by the While the other carrier travels across the entire Width of the foot.- As shown in the 41 against the action of. s ring 50.

drawings, the left lining thread carrier 36 is 35, 36, is so timed with relation to the movement ofthe main thread carrier, that the former will follow the latter at a uniform distance. In this way sufficient headway is obtained for the main thread carrier to always roperly place its thread into the sinkers beore the splicing thread carriers introducel their threads into the same.

In order to release and arrest the

splicing thread carriers

35, 36 at the proper time, while the main thread carrier 27 travels over the entire width of the sole, there are provided four crank-

levers

41, 42, 43 and 44, of which lever 41 is ivoted to a left head 45 of the'machine, whi e lever 42 is pivoted to a right head 46 thereof.

Heads

45 and 46 receive the necessary inward movement for narrowing the sole, by

screws

47, 48, which are operated in the usual manner.

Levers

43 and 44 are fulcrumed to the stationary frame 21 of the machine.` It will thus be seen that levers 41, 42 articipate in the lon itudinal movement ofp heads and 46, Whi e levers 43 and 44 are immovable in a longitudinal direction.

Levers

41, 42, 43, 44 are ada ted to en age bars 29, 30 and to arrest suc bars antgl guides for a certain period after t e main thread guides have begun to move. Lever 41 is pivoted to head 45 at 49, and is influenced by a spring 50. The upper arm of lever 41 has a pair of noses`51, 52 which are adapted to be projected into the ath of

lugs

53, 54 secured to the left ends of

ars

29, 30 respectively.

Lugs

53, 54 have beveled lower sides so that when bars 29, 30 travel towards the left, the lugs will tilt lever When bars 29, 30 bear, at the en of their race towards the left, against stops 55, 56, lugs 53, 54 will clear

noses

51, 52, so as to permit spring 50 to tilt lever 41 and thereby arrest bars 29, 30 against movement towards .the right. The lower arm of lever 41 is adapted to be engaged by a projection 58 of an arm 59 secured to shoggmg-bar 22 and reciprocating with the latter. When rojection 58 engages lever 41, the latter wil be tilted, so that noses 51 52 are swung out of the way of

lugs

53, 54, respectively. If different kind of work is to be made on the knitting machine, lever 41 is made inoperative by ermanently depressing its u per arm. or this purpose there is pivotek tothe latter a latch 60 adapted to enga e a in 61 secured to a perforated plate 62 o hea 45. If latch 60 is turned upwards, its shoulder 63 will engage pin 61 and thereby depress the upper arm of lever 41, to swing

noses

51, 52 permanently out of the path of

lugs

projecting upwards from machine frame 21. lhe up er arm of lever .43 has a nose 66 ada te( to engage lug 53 of lower bar 29, whi e its lower arm, being .influenced by a spring 67 is adapted to engage arm 59 or projection 58. Y

YVithin a guide-way of standard is received a slide 68 having a forwardly projecting abutment 69. VVhen slide 68 is in its lowered position, abutment 69 will be in the path of lug 53 of bar 29, to constitute a first displaceable stop for such-bar, when the latter is moving towards the left. This stop is used while the thread guides 35, carried by bar 29, areA operated to reinforce the soleportion 37 of foot 38. After the foot has been knitted up to l-ine 40, abutment .69 is brought outof the path of lug 53, by raising slide 68 into the position shown by dotted lines in Fig. 8. In'this way, bar 29 is free to. continue its race towards the left beyond rst stop 69,. until it bears against second stop 55 hereinabove referred' to.

Lever 42 is fulcrumed at 70 to end plate 71 of right head 46 and is influenced by a spring 72. The upper arm of lever 42 is provided with a nose 73 adapted to engage a beveled lug 74 on the right end of lower bar 29, the latter being guided in'a perforated plate 75 of head 46. Lever 44 is fulcrumed at 77 to a bracket 76 of frame 21, the lever being'influenced by a spring 78. Nose 79 of lever 44 is adapted to engage a beveled lug 8O on the right end of up er bar 30. The lower arms of levers'42 an( 44 are adapted-to engage a projection81 of an arm 82 secured to the right end of shogging-bar 22. When bars 29, 3() move towards the right, the beveled lower sides of

lugs

74, 80 permitthe same to pass beyond

noses

73, 79, thereby tilting

levers

42, 44 against the action of their springs. After lugs v74,80 have. cleared

noses

73, 79, they springs will swing

levers

42, 44 back into their original position, so thatV revent bars 29, 30. from moving towards t e left, until

levers

42, 44 are again engaged by projection 81. Assuming the shogging-bar 22 and the Shogging-

shafts

23, 24, 25, to be in their extreme -1 right hand position, the main carrier y27 will be in vertical alinement with s licing carrier 35. of the sho ging-bar and shogging shaftsV towards the eft, the main carrier 27 will have been takenI along, while the bars 29,340, carrying the lining carriers, are locked against movement by the engagement of

lugs

74, 80 After the main carrier has traveled for a short distance, (Fig. 1),v so as to properly place the main thread between beaks 83, 84 of sinkers 85, projection 81 will engage lever 42 and tilt the same; In this way nose 73 will be "withdrawn from lug 74, so that bar 29 will also start its movement towards the'left, and

Duringthe first part of t e movementi l the lining vcarrier 35 will follow the main carrier 27 at the distance desired, to place the ment with notch 34 of bar 30.

lining thread 86 upon the top of -the main thread 87, which had alread been pro erly laid in the mouths 88 of sin ers 85. Yhen the lining carrier 35 arrives at4 the straight line 89, formed between soleortion 37 and top 90 of foot 38, bai' 29 wil bear against abutment 69, so that the 'latter, together with carrier 35, will be arrested.v During the last portion of travel of bar 29, lever 43 has been tilted by the en agement of thefbeveled side of lug 53 wit nose 66. When bar 29 has arrived at its terminal left position nose 66 will clear lug 53, so as to be projected in the path of such lug and to thereby prevent the movement of bar 29 towards the right during the beginning of the return stroke of the shogging-shafts.

After bar 29 has engaged abutment 69, the main carrier 27 alone will continue to travel towards the left for the desired distance, viz: until it has passed straight line 91 formed between top 90 and sole-portion 39 vof the foot, whereupon projection 81 will e age lever 44. In this way the latter Wi be tilted to withdraw nose 79 from lug-S0 of bar 30,- whic-h, together with lining carrier 36, will now start its travel towards the left. Lining carrier 36 will thus follow main carrier 27 at`the same distance at which carrier 35 had previously followed carrier 27. the end of this movement, the main carrier will be first arrested by bearin against the usual stop of head 45, (not s own), while carrier y36 will continue its movement until it bears against sto v nose 52 which is t en projected behind lug 54. Stop 56 is so arranged with relatin to the main carrier, that in their terminal posi-4v tion,

thereby bringing the lever out of engage- Sto 56 is then swung out of the path. of bar 30 y tilting lever 92, that carries stop 56, on its pivot 93. Bar 30 is now moved to its extreme left position, so that its carriers will not interfere' 56, when it is locked by:

The shogging-bar and-shaftsl Awill now start their travel towards theright, j the operation corres ondirig4f in all respects the engagement; of nose 51 with lug 53. After carrier 27 has traveled for the desired distance, to properly lace its thread into the sinkers, nose 51 wi lbe withdrawn from lu 53 by' the en agement of projection 58 with lever 41. repeated until the toe is completed, the narrowing being effected by the usual inward movement of the heads 45 'and 46.

It will be seen that by my improved knitting machine, means are provided for placing the main thread and lining thread always in the same relative position into the mouths of the sinkers. As the threads retain the same position during the knitting operation following, the thread for reinforcing or lining the stocking will be laid true against the ground thread, so as to be invisible, and prevent any contact of the ground thread with the flesh of the wearer.
