' ATTOR N EYS l at'ented Dec. 31, 1929 UNITE STATES PATENT ()FFICE ASHER- KIPNIS, OF BROQKLYN, NEV YORK, ASSIGNOR TO REPUBLIC KNITTING MILLS OF BROOKLYN, NEW YORK, A. GOPARTNER-SHIP CDMPOSED OF ASHER KIPNIS, JOSEPH KILPNIS, AND DAVID L. REICHELL KNITTING MACHINE Application filed November 26,1928. Serial No. 321,985.

This invention relates to knitting machines and more particularly to an improved attachment for knitting machines which permits a fine adjustment of the stop block or blocks.

A further object is to provide a means which permits the stop block to be very accurately adjusted on the yarn carrier bar, for example, an exact needle distance adjustment so that there may be a proper registration of yarn carriers so that the needles may knit, in a continuous fabric, strips of different colors knitted together smoothly and continuously without any overlap or 5 projection from the surface such as is common in making longitudinally striped material in the past.

Heretofore it has been common practice to provide yarn carrier bars with a series of recesses or openings and with a pin or pins in the stop blocks so that a fine adjustment of the stop block on the bar is impossible as the space necessary for the series of openings precludes the possibility of anything but a limited adjustment that is not sufficient for accurate registration of the yarn with the needles to cause the needles to knit the various colored yarns in longitudinal stripes.

With my improved mechanism or attach ment the adjustment can be made such as to cause a proper registration and produce a flat knitted fabric which is a vast improvement in the art.

A further objectis to provide an attachment of the character stated which enables the proper registration of the yarn carriers so that yarns of different colors are presented to a single needle which knits both colors alternately on opposite sides of the fabric.

\Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arragements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure l is a view in vertical section through a portion of a knitting machine showing suflicient parts thereof to illustrate my invention;

Figure 2 is a plan View of Figure 1;

Figure 3 is an enlarged plan view of my improved stop block in position on the carrier bar;

Figure 4 is a view in section on the line 4-4 of Figure 3;

Figure 5 is a View in longitudinal section 011 the line 5-5 of Figure 3;

Figure 6 is a perspective view showing an assemblage of needles and yarn carrier guides with a needle in position to engage yarns of different colors. t

1, 1 represent inclined needle beds having grooves 2 therein in which needles 8 are mounted and guided in their movement. 4:, 4: represent yarn carrier bars on which yarn carrier blocks 5 are mounted in the customary manner, and yarn carriers 6 are connected to the blocks 5 and have spring held flexible or yieldable guides 7 at their ends through which yarn 8 is fed to the needles 3. 9 represents carriage plungers, such as commonly employed, and the parts above described constitute standard equipment and form no part of my present invention except in combination therewith.

My invention has particularly to do with an improved construction mounting and manner of adjusting stop blocks 10 which control the position of the yarn carrier blocks 5. The mechanism at opposite sides of the machine is duplicated so that the description of the parts at one sideof the machine will apply alike to both.

Reference is particularly made to Figures 2, 3, 4 and 5 of the drawing.

The upper or outer portion of the bar 4: has, tapering sides corresponding with the recessed under face of the block 10 so that while the block is free to slide on the bar it cannot be displaced in any other direction.

Instead of providing in the face of the bars 4 openings or sockets such as commonly employed, I cut transverse grooves or notches in the bar which are of exact needle distance apart, that is to say, the notches as indicated by the grooves or notches 11 in the bar 4 are spaced apart a distance exactly equal to the distance between the needle grooves 2 in the beds 1.

On the block 10 I secure a spring tongue 12 fixed at one end to the block, as shown at 13, through the medium of screws or other attaching devices. This spring tongue 12 projects beyond the block 10 and at its free end has a downwardly projecting tongue 14 which engages in a groove or notch 11 so as to securely hold the block in exact position.

To facilitate the lifting of the spring tongue to release it from operative engagement with the bar 4 I provide a transverse finger gripping strip 15 on the free end of the tongue 12 which may be readily grasped between the thumb and finger so as to manipulate the tongue.

By reason of this construction the yarn carriers can be placed in proper register so that two colors of yarn, as indicated in F igure 6, cross each other for engagement by a single needle, and this needle knits the two yarns so that yarns of different colors alternate longitudinally of the material on opposite sides of the material, and a smooth, continuous knitting of the material is had without any raised or other imperfection in the smoothness of the material.

While I have illustrated what I believe to be a preferred embodiment of my invention it is obvious various changes and alterations might be made in the general form of the parts described without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. In a knitting machine, the combination with a carrier bar having transversely extending notches or grooves therein, of a stop block movable on the bar, a spring tongue on the stop block, and a lip on the ton ue adapted to engage in the grooves of the ar, said grooves of the bar being spaced a distance exactly the same as the distance between the needle grooves of the machine.

2. In a knitting machine, the combina tion with a carrier bar having transversely extending notches or grooves therein, of a stop block movable on the bar, a spring tongue on the stop block, a lip on the tongue adapted to engage in the grooves of the bar, said grooves of the bar being spaced a distance exactly the same as the distance between the needle grooves of the machine, and a fingerpiece on the free end of the tongue extending transversely of the tongue and adapted to be grasped to lift the tongue out of holding engagement with the bar.

Signed at New York, in the county of New York and State of New York, this 23rd day of November, A. D. 1928.

ASHER- KIPNIS.
