This invention relatn'to a fiat hosiery frame fitted with needle bars subdivided in each section.

Frames of this type are known already and used particularly in the manufacture of hosiery when the heel pieces have to be worked onto the legs and, in the meantime, the middle portion of the goods is to remain on the needles and no rows are temporarily to be added to it. The various parts of a needle bar were hitherto disposed in one line, with the lines of separation passing usually through the web between two needles, so that the border needles on both sides of such. a dividing line could be securely held in position only in case of a coarse and medium gauge. A fine gauge was out of the question in connection with needle bars subdivided in the manner de scribed. In addition, needle bars of this kind suffer from the further defect that the number of needles and the width of the middle part of the bar could not be varied, so that the width of the portion of the goods remaining on the needles had to be the same for all sorts of hosiery and, for example, the width of the heel pieces could not be altered. This drawback could not be eliminated even if a movable shorter needle bar was arranged in front of the central portion of a bar extending over a section and having only its ends -equipped for the insertion of needles, since in this case the various bar portions were equipped only for the reception of a certain number of needles and no arrangements were made for distributing the needles over the parts of the section in a different order also. As in other cases where the middle part was fitted with lateral wings to which, separated from the needles of the central part, one or two special needles were attached, it was merely intended to lower individual needles within the side parts together with the middle part in order to form a ladder parallel to the edges of the heel pieces to facilitate the transfer of the latter. known that the above-mentioned defects of the subdivision of sections can be remedied by the alteration of the known devices which particu larly do not permit widening of the central portion and a corresponding narrowing of the side portions.

To avoid these defects connected with the known devices the invention provides that the side parts, at the ends adjacent each other, in addition to the border needles, have portions longer than a needle division which do not have recesses for the insertion of straight needles, whereas the portions of the middle piece, which overlap them, possess so many fixing points for It remained, however, un-' ermany September 15, 1931 needles bent like a knee in the lower part of their stems that the number of needles connected with the middle part may be varied without producing a gap in the section.

By way of example, one form of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side view of a section with the middle part in operative position; Fig. 2, a plan thereof; Fig. 3, a side view, similar to the one shown in Fig. 1, but with themiddle part drawn 66 back; Fig. 4, a plan thereof; Fig. 5, a plan on a larger scale of a portion of the arrangement shown in Figs. 1 to 4; and Fig. 6 explains another possibility of arrangement.

Referring to the drawings, the needle bars of 70 a section comprise the two side parts 1 and 2, the middle part 3 and the additional parts 4 and 5 which are firmly connected with the middle part 3 and adjustable therewith. When in operative position, the parts 1, 2 and 3, which have essentially the same form, will be arranged in a line, as indicated in Figs. 1 and 2. In each 0! these three parts the needles are fixed in the same manner,- so that the heel 6 thereof is disposed in the same direction as the stem 7.

However, according to Fig. 5, the needles fixed in the three bar members 1 to 3 do not extend as closely to the separating lines 8 between the various bar members as is desirable to insure a uniform needle arrangement free from gaps, since on both sides of the line 8 one needle has been omitted, so that the border needles fixed in members 1 to 3 are sufilciently removed from the free ends of those bar members to be reliably held in position. The omitted needles 9 are fixed in the additional parts 4 and 5 disposed outside the row of bar members 1, 2,3 with their heels 10 bent out of the direction of their stems. Otherwise, these needles are constructed so that their loopforming parts are exactly in line with those needle heads that are held by the middle part 3, so that, when the part 3 is in operative position, not only its own needles but also'those of the additional parts 4 and 5 will be in a row with the needles of the side parts 1 and 2.

The additional parts 4 and 5 overlap the separating lines 8 between the bar members 1 to 3 and may be of any length, so that any number of grooves 11 may be provided therein for holding correspondingly formed needles. This makes it possible to fix on both sides of the separating lines of two bar parts the necessary needles either in the main bar members 1, 2, 3 or in the additional parts 4 and 5. If one or several border needles are removed from the side parts 1 and 2 and replaced by needles fixed in the additional parts 4' and 5, it becomes possible to increase at will, within certain limits, the number of needles which during the withdrawal of the middle part are taken along into the position indicated in Figs. 3 and 4 and thus rendered inoperative. The middle part 3 will therefore be equipped only tor as many. needles as have to be stopped in such a case while any number of additional needles may be fixed on both sides in the additional parts' with the middle part and the 4 and 5 connected side parts 1 and 2 of the bar receive only as many needles as are needed to produce the desired heel width.

The device described may ways. a middle piece between the line with the latter when be varied in many tioned in the row of the additional parts 4 and 5 and made integral therewith, it being essential of course in this arrangement that the ends of the side parts facing each other be overlapped by additional parts of the middle piece which should haveas many fixing points for needles asis necessary for varying the-number, of needlesthat can be ;stopped and for adapting it to requirements without producinga gap in the section.

.How the various bar members should be constructed to insure unfailing uniformity in the fixing of needles and how the adjustable parts of the sections should be moved must lie-decided in each case, and quite a large number oi possibilities covering these points are known already.
