- Figs. 7 and 8 are lan views of part of the motion-translating ever and its associated. elements at different points in their movements;

- Fig. 10 is a side elevation of the mechanism for transmitting movement to the guide bar in the desired manner;l Y
- Figs. 13 and 14 are detail views 0f.. the connection between the rackingv barfandthe guide bar.
- each needle bar descends just after the individual thread guides pass between the needles to the same side of the machine as that needle bar.
- the yarns are fed to the guide bars from the usual warp beams 71 mounted in racks 7 2.
- lVe provide permanent operating mechanism originating and controlling all longitudinal movements of the guide bar, and absolute/ely independent pattern means indicating to the operating mechanism which movement it is to give to the guide bar.
- the operating mechanism can produce only movements of a definite series based on a predetermined linear unit,-such as the distance required to lay the thread in front of one needlewhile the pat-tern means merely releases the movements in their desired order. These movements are unidirectional, are each independent of its predecessor, and may bc in either direction as selected by the pattern means.
- jacquard mechanism For selecting means we have shown a jacquard mechanism, but its function and its relation to the knitting are entirely novel.
- the individual jacquard pins and perforations have always controlled specilic knitting elements or positions but we continually change their operative relation to the knitting and let them designate merely the length and directionl of a movement.
- the point of application of the movement is not designated by the paper pattern at all, but is determined by the cumulative sum of the previous movements of the guide bar. In this way the pattern need not be punched from any laborious calculation based on a zero position, but can be transcribed into pei-forations which actually correspond to the yarn ,movements
- the direction of movement is similarly governed as will be explained in detail later.
- e means transmitting kthat movement the guide bar in the desired manner (Figs. 2, 10, 11, 12, 13 and 14).
- A. Tl'ie se ctng mana-This part of our, mechanism includes the selecting device proper, for which we prefer to use a form of jacquard-and the 'device enablingthe jacquard to make an advance selection while the remainder of the apparatus is carryingv out the previous selection.
- the jacquard has the usual, perforated paper pattern advanced intermittently over a drum 111 by any suitable means driven from the main shaft 105, the drum being moved against a row of jacquard pins Aor needles 120 after each advance of the pattern and the pins to be selected asslng through holes in 'the pattern an not being pushed back all in a manner'similar to that described in the R. Zahn Patent No. 1,049,556, dated January 7, '1913.
- the pattern is a strip of heavy paper and is kept in register by'any of the customary registry pins 112.
- Each jacquard pin 120 is secured to a bar 121 sliding horizontally in a jaw on the main frame 100 to which bar can be attached any desired jacquard safety devices.
- a wire 122 adapted to move with the bar 121 connects it pivotally to a horizontal selectingbar 140 mounted at its rear end in a jaw on the main frame 100.
- This rea-r end of the selecting bar is curved on its edges in a manner which enables the front end of the bar to ti up a little if necessary.
- Projeeting laterally Yfrom vertical arm 160 of each L slide are two low lugs 161 between which the associated selecting bar slides, the selecting barlthus lifting the L slide whenever the selecting bar itself is lifted.
- each selecting. bar ⁇ 140 at the lower edge is a-'toe 1415and'just back of this toe there is 'a deep notch or instep 142 in the lower edge -of the bar.' Situated just beyond the freeends .of these bars is a shaft 149 on which are-.pivoted two ⁇ adjusting claws 150 andi155 which: lie respectively below and above the row of selecting bars 140.
- the claw 150- when swung. up is adapted to enter thefnotches 142 .of such selecting bars as are pushed back by the paper'pattern and to contact.
- the translating melma-It is in this iapo poespas part ofthe apparatus that the power to operate the guide bar is introduced, the movements originating with cam 206cm the drive shaft 105.
- This cam is an internal groove cam and operates a bell crank lever 210 connected to a translating lever 200 by a link 211.
- This translatin lever may take the form of an open four-si ed frame pivoted at the center of the to and bottom and linked to the bell crank ever at one side.
- the translating lever is pivoted at its middle points 201 and the lever is swung through a fixed arc by the link 211.
- Each half of each arm of the lever 200 is devoted to the translation of movement for a single guide bar, so we shall confine our attention to one half of the upper arm.
- the arm is grooved lengthwise on its lower side and a keeper 202 having nine holes 203 therein slides in this groove (Fig. 4).
- the translating lever can be consi ered as at the beginning of its stroke and the slide frame as at zero.
- the mechanism for engaging and ⁇ disen gaging the racks and thepinion are shown in Fig. 10. It is driven from a cam 306 on the main shaft 105 and controlled b a direction wire 167 connectedby a bel crank lever 166 to the particular vertical arm 160 which controls direction for that-guide bar.
- the central elements in this part of the mechanism are a double jaw 320and an associated rocking sleeve 330.
- This double jaw member 320 has two jaws 321 facing each other at a sufficient distance-iapart-to enable; one jaw or the other to enga ey one off-the" pins 331, 332, on the rocking s eeve, but not close enough to allow both4 jaws' to' grip pins at the same time.
- the double jaw member is pivoted at 323- ⁇ on one end of a bell crank lever 316 which fin turn is pivoted on the main frame 100'.
- the direction wire 167 is connected to the double jaw member 'near' the jaws 321 at such an vangle that'when the pattern'does-lnot-liave.
- the operating cam 306 imparts a linear -reeiprocation to the double jaw member by means of a bell crank lever 310 pivoted on the frame, a rod 312 and the bell crank lever 316.' The osition of the double jaw member when pu led b the cam 306 is partly indicated by dotte lines in "Fig, 10, and it will be seen that the reciprocation is directly away from and towards the rockin sleeve 330.
- pins 331 and 332 are so located on the sleeve with relation to the reciprocatory movements of the double jaw member, that if one pin is engaged b that member the sleeve will rock 1n one irection and if the other pin is engaged in the opposite direction.
- the rocking sleeve is linked to the yoke 340 by a rod 333, a bell crank lever 334 pivoted on the main frame and a lost motion link 335 between the bell crank lever and the yoke.
- a moments examination of this 'mechanism will show that when the double jaw member is in the up position (shown m solid lines in Fig. 10) neither of the racks 350 will be in engagement with the pinion 560, no matter which jaw 321 is in engagement with its pin, but when the double jaw is pulled down to the dotted position one or other of the racks will mesh with the pinion.
- the inion 360 is coupled directly to thel ide ar by any suitable means such as own in Figs. 11 to 14.
- the shaft 361 on which the mion 360 is mounted also has on it a bevellgear 363 transmitting the movements by bevel gear 364 to a vertical shaft 365 and a pinion 366.
- This latter pinion 371 on a racking bar 370 which takes the place of the transfer bar heretofore used.
- the racking bar is fastened to the guide bar by means of a T-headed bolt 372 on the end of the guide bar.
- This bolt slides in a curved slot 373 in a plate 374 fastened on the end of the racking bar at right angles to the guide bar.
- the slot is undercut leaving shoulders 375 which hold the T-headed bolt from coming out, thus coupling the guide bar positively to the operating mechanism and at the same time ermitting the cradle to rock the guide bar back and forth.
- the pinion is so made that the space between two of its teeth should be opposite the tooth 362 after each movement. If for any reason it is not the pointed wedge or tooth will bring it into register and thus automatically bring the gulde bar into register.
- the tooth 362 also serves as a lock to hold the guide bar in (position while the racks 350 are disengage What we claim is:
