UNITED STATES RANDOLPH C. GEBER'S, OF EAST ELMHURST, NEW YORK.

KNITTING APPARATUS.

Application filed September 8, 1922. Serial No. 586,873.

To all whom it may concern:

Be it known that I, RANDOLPH C. GEBERs, formerly a citizen of Hungary, and a resident of East Elmhurst, Long Island, in the county of Queens and State of New York, have invented a certain new and, useful Improvement in Knitting Apparatus, of which the following is a specification.

My invention relates to a process of manufacturing hosiery and one form of apparatus capable of use therefor and has for its object to produce full-fashioned, fiat, knitted hosiery at less expense, more rapidly, with less waste, and with less complicated machinery than has been possible heretofore.

Other objects of my invention will be apparent from the following description and from the accompanying drawings of one embodiment thereof, in which- Figure 1 represents the lower part of the leg and the heel portions of a stocking at the completion of the first stage of manufacture in accordance with one embodiment of the present invention, shown for purposes of. illustration with the heel .portion at the left still engaged with the needles and with the heel portion at the right removed from the needles;

Figure 2 a continuation of the manufacture by one embodiment of the present invention of the stocking, shown for purposes of illustration with the heel portion at the left disengaged from the foot portion and with the heel portion at the right sewed to the foot portion;

. Figure 3 a perspective of a portion of the needle bar of a flat knitting machine with one embodiment of the invention appliedthereto; F

Figure 4 a view similar to F igureB with the parts in different position to illustrate the utilization of the invention;

Figure 5 a section on the line 7-7 of F igure 3 looking in the direction of the arrows;

Figure 6 a section on the line 8-8 of Figure 4 looking in the direction of the arrows.

Similar reference characters refer to similar parts throughout the drawings.

By the present invention, the hose is completed on the leg machine without change, thereby saving the time and labor necessary to take the partly completed hose from the leg machine and place it on the footer and preventing the loss resulting from the necessity of unraveling the edge on heel por-.

tions B and in portion E at the bottom of the leg. In the embodiment illustrated in the present drawing, the needles F of the leg machine (Figure 1) always remain engaged with the bottom of leg portion heel portions B are being knitted. When the heel portions B are completed the thread corresponding to said portions is laid aside, and the entire foot portion completed on the same machine, the top of the foot portion forming a continuation of and being integral with the leg portion. As the bottom of the sole G (Figure 2) is not joined to the heel portions B by this method of knitting, these two parts can be sewed together as indicated at the right of Figure 2, and then the stocking completed in usual manner by sewing the entire back and bottom.

An apparatus capable of carrying out this process is illustrated in Figures 3, 1, 5, and 6. A needle bar consisting of needle holding sections 1 and 2 is shown. These sections may move together as a unit, or one of the sections may be moved with respect to the other section, as may be desired. Movement is imparted to the needle bar as a whole in the usual manner, section 1 being shown with depending guide lugs 3 in which are mounted rotatably a rod 4 connected with ,a

lever 5 secured to a shaft 6 to impart ver- A while the tical and lateral reciprocation to the needle bar as a whole in well known and usual man'- ner. Section 2 is cut away at 21 (Figure 6) to fit over a reduced intermediate portion 11 of section 1, and is provided with downwardly extending, vertical extensions 22 having inwardly extending, horizontal flanges 23 on which rest rods 24 fixed in the top of section 2 and slidably extending through intermediate portion 11 of section 1. Com pression springs 30 surround rods 24 between intermediate portion 11 of section 1 and inwardly extending flanges 23 of section 2 and tend normally to keep section 2 in horizontal alignment with section 1.

During the knitting of the leg portion,

- both sections 1 and 2 reciprocate in unison.

When the leg portionA is finished, however, and it is desired to knit only the heel portions, section 2 of the needle bar, which cor- I responds to the width of the leg portion between the heel portions, is maintained above the level of the goods so that the,need 1es do not become disengaged therefrom. Thls may be accomplished in any desired manner as by a stop 40 mounted on a shaft 42 and operat ed in any desired manner, which is swung, when the needle bar is in raised position, from its normal position (Figures 3 and 5) to a position underneath section 2 of the needle 'bar (Figures 4: and 6'). When the needle bar then is lowered stop 40 will maintain section 2 in raised position so that the needles of said section will remain above the level of the goods and will not become disengaged therefrom. The tension of the finished leg portion is released so that as the heel portions are knitted the needles 25 of section 2 will not tear the leg portion. Stop 40 may be provided with adjustable means 41 of any desired type so that the proper height can be maintained. It will be seen that as the needle bar is reciprocated for forming the heel portions, section 2 always will be maintained in upward position and with its needles in engagement with the bottom of the leg portion.

In order to keep heel portions B under proper tension while they are being knitted,

I a wire or similar device 50 (Figure 4) may be slipped under each portion after a few rows are knitted and secured to any fixed part by a rubber strop 51 or similar tension device. The goods already knitted will be held under stationary tension by the usual take-up roll (not shown) which will not be operated during the knitting of the heel portions B. When the knitting of the foot part is resumed, the sole portions, outside the middle portion connected directly with the take-up roll, will be engaged by the regular hook bar (not shown) to provide necessary tension therefor.

When the heel portions are completed it then is necessary only to start knitting the sole and top of the foot as indicated in dotted lines at the left of Figure 2 to complete the knitting of the hose on the single leg machine. When removed from the machine the heel and sole parts are sewedtogether as indicated at the right of Figure 2 and then the entire back and sole sewed together to form the completed hose in customary manner.

The additional parts shown in Figures 5 and 6 of the drawings are standard appliances. 50 indicates a thread carrier of the usual type, 51 sinkers of the usual type to push the thread between the needles, 52 the knocking-over bits to hold the goods in position, and 53 the usual presser against which the needles are pressed to close their spring loop.

The knitting machine will also be understood as having the usual narrowing fingers for the purpose of picking up the stitch from a needle 25 and moving it over to the next needle; four of such narrowing fingers are usually employed, one at each end of the needle bar and two adjacent thesection 2 thereof. When the machine is operating with the section 2 of the needle bar maintained in raised position, the two central narrowing fingers may be spread apart in any suitable manner which it is not considered necessary to describe in detail, to prevent interference with the section 2 of the needlebar.

Many modifications of my invention will be apparent to those skilled in the art without departing therefrom or from the scope of the claims, my invention not being limited to the particular embodiment chosen for purposes of illustration but consisting of the process and one embodiment of an apparatus therefor capable of completing the knitted portion of a stocking on one machine without the necessity of change.

What I claim and desire to secure by Letters Patent is:

1. In a knitting machine, a needle bar having a part of its needle supporting side cut away to provide a reduced portion in said bar, a needle bar section located in said cut away part and adapted to seat against said reduced portion, a guide member engaging between said needle bar section and the needle bar permitting said section to slide relative to the needle bar substantially in the plane of the needles, and a stop member adapted to engage the needle bar section to hold the latter against reciprocation with the needle bar.

2. In a knitting machine, a needle bar having a part of its needle sup-porting side cut away to provide a reduced portion in said bar, a needle bar section located in said cut away part and adapted to seat against said reducedportion, a spring yieldingly urging said section against said reduced portion, a guide member engaging between said needle bar section and the needle bar permitting said section to slide relative to the needle bar substantially in the plane of the needles, and a stop member adapted to engage the needle bar section to hold the latter against reciprocation with the needle bar.

3. In a knitting machine, a needle bar having a part of its needle supporting side cut away to provide a reduced portion in said bar, a needle bar section located in said cut away part and adapted to seat against said reduced portion, a guide member engaging between said needle bar section and the needle bar permitting said section to slide relative to the needle bar substantially in the plane of the needles, a stop member adapted .to engage the needle bar section to hold the latter against reciprocation with the needle bar, and a special tension device engageable with the goods being knitted on the needle bar when the needle bar sectlon 1s held against reciprocation as aforesaid.

In testimony that I claim the foregoing, I have hereunto set myhand this 30th day of June 1923.

RANDOLPH C. GEBERS.
