STRAIGHT-KNITTING FRAME.

Application filed November 13, 1924, Serial No. 749,646, and in Germany December 18, 1923.

My invention relates to straight knitting frames and has particular reference to such a frame provided with a movable knockover comb the knock-over sinkers of which are-provided with a locking-in throat.

The known knock-over sinkers provided with a locking'in throat are moved elther in a horizontal and vertical direction only or, if the knock-over sinkers are rotatable,

the pivot point is not arranged in such a manner, that, by simply turning the knockover sinkers, the loops may be transferred from the jack sinkers directly to the knockover sinkers provided with a locklng-in throat.

The object of the present invention is to provide means which allow this direct transfer of loops for which purpose the knockover sinkers are pivotally arranged about an axis passing through the points of their nibs.

In the accompanying drawings the invention is illustrated diagrammatically by way of example. Figs. 1 and 2 are two views of the device according to the invent-ion showing the parts in two different positions.

Figs. 37 are detail views of the knock-over comb and the jack sinkers in different working positions.

The knock-over sinkers 1, provided with a locking-in throat 1, a nib 1 and a beak 1 are arranged in a horizontal bar 2 which is pivoted to the ends of arms 3 of double armed levers 3, 9 mounted upon a shaft 4-.

The pivot axis of the bar 2 around the arms 3 is arranged in the same axis as the points of the nibs 1 of the locking-1n throats 1 of the knock-over sinkers 1.

Mounted upon a shaft 5 journaled in the machine frame is a disc 8 carrying cams 6 and 7. The free end of the arm 9 of the double- armed lever 3, 9 carries a roller 9 bearing against the disc 8. Upon a second shaft 10 a bell crank lever 11, 12 is arranged the arm 11 of which also carries a roller 11 bearing against the disc 8. Pivoted to the other arm 12 of the bell crank lever 11, 12 is a rod 13 the free end of which is connected to an arm 14 pivoted to the axis of the bar 2. The jack sinker is designated 15 and 16 is the needle.

Normally the parts are in the position shown in Fig. 1 in which the rollers 9 and 11 carried by the arms 9 and 11 bear against the circular part of the disc 8. The knockover sinker 1 assumes the position shown in Fig. 3 in which by advancing of the jack sinker 15 the sinking of the loops begins. 4 shows the pressing off, following the slnking of'the loops. Thereupon the cam 6 engages the roller 11 on the arm 11 which is shifted. Hereby the arm 12 and by means of the rod 13 the arm 14 connected to the bar 2 is lifted. The knock-over sinker 1 thereby come into the position shown in Figs. 2 and 5. As in this movement the knock-over sinkers 1 turn about the point of the nib 1 of the locking-in throat 1, the knock-over point of the knock-over sinker 1 approaches the jack sinker 15 in such a manner, that the loop, without making a special way, is directly and safely taken over from the knock-over sinker 1. Fig. 6 shows the knocking-over proper, whereas Fig. 1 illustrates the locking-in.

What I claim is:

1. In a straight knitting frame, the comblnation of knock-over sinkers each provided with a locking-in throat, a nib and a beak, with jack-sinkers, a bar carrying the knockover sinkers and means for turning said bar parallelly to itself in such a direction that the beak of each knock-over sinker approaches the loop-carrying end of the appertaining jack-sinker, the points of fulcrum of said bar being situated in the ideal line passing through the ends of the nibs of the said knock-over sinkers, as set forth.

2. In a straight knitting frame, in combination jack sinkers, knock-over sinkers having each a locking-in throat, a nib above the latter, and a beak below the same, a bar carrying these knock-over sinkers, doublearmed levers carrying this bar at one of their arms, the points of fulcrum of these levers lying in the ideal line extending through the ends of the nibs of the said knock-over sinkers, and means engaging said double-armed levers at their other arms and rocking them in predetermined intervals, as set forth.

3. In a straight knitting frame, in combination jack sinkers, knock-over sinkers having each a locking-in throat, a nib above this latter, and a beak below the same, a bar carrying these knock-over sinkers, double-armed levers carrying this bar at one of their arms, the points of fulcrum of these levers lying in the ideal line extending through the ends of the nibs of the said knock-over sinkers, a shaft and a cam thereon, a lever rocked by this cam in predetermined intervals, arms connected with this lever, and rods connecting these arms with the free arms of said double-armed levers, as set forth.

4. In a straight knitting frame, in combination jack sinkers, knock-over sinker-s having each a locking-in throat, a nib above this latter, and a beak below the same, a bar carrying these knock-over sinkers, double-armed levers carrying this bar at one of their arms, other double-armed levers supporting the first-mentioned ones at their upper ends, the points of fulcrum lying in the ideal line extending through the extreme ends of the nibs of the knock-over sinkers, a shaft and two cams thereon, a lever arranged to be rocked by one of the cams in predetermined intervals, arms connected with this lever, and rods connecting these arms With the free arms of the first-mentioned double-armed levers, the second cam being arranged to rock the double-armed lever mentioned in the second place in predetermined intervals, substantially as de scribed.

In testimony whereof I aflix my signature.
