ROUND-KNITTING MACHINE.
Application med February 7,' 1925, Serial No. 7,596, and in Germany February 14, 1924.
A l shape of the human body. In th pearlingknitting machines as heretofore suggested by the previous art, it was the usual course to effect the reduction or enlargement of the diameter in jumpers, skirts, sweaters, gaiters i and the like by the usual reduction or diminishing of the meshes, or by alternately loose and fast knitting, with the inconvenience, however, that this resulted in a distortion of the proportions of the several constituent parts of the pattern itself, while,
on the other hand, the manufacture of .such
goods from ordinary flat or tubular knltted fabric by the cutting-out and subsequent combination of sections required a prevlous v stretching and the use of a model for the preparation of the Vseveral parts and the union thereof.
With my invention this diiiculty is overcome by a novel construction of pattern- 3u producing knitting loom by means of which it is possible to combine the pattern fabric with additional knitted portions, whichlby a kind of 'tension produce the same result as has been obtained heretofore by the reduction or diminishing of meshes.
In the round-knitting machines as heretofore constructed for patterned goods and .operating with or without jacquard for` allpearling goods with superimposed single 4.0 cylinders and double-tongue needles cooperating therewith, it has been posslble to manufacture smooth pearled and patterned oods. This kind of manufacture, however, ailed to produce the tubular goodsreferred to and adapted to hug the human body.
Now, in accordance with this invention it becomes possible to manufacture the goods referred to, such as Cuffs, gaiters, four-inhands, ties, stocking shafts, sleeves, gloves,
sweaters, bodices and stays, caps, jumpers, ladies skirts and other garments and the like in the regular manner and withoutI Seam.
The deviceis shown in the accompanying drawing by way of exemplilicatlon, 1n Fig.
1 partly in elevation and partly in longitudinal section through a round knitting machine in accordance with my invention with the `needles and sinkers shown diagrammatically only by way of clearness lof illustration; in Figs. 2-8 the cooperation of the needles with the draft sinkers and pushing sinkers is illustrated, Fig. 2 is an aggregation of four different views showing the sinkers in different positionswith relation to the double-hooked needle and respectively in side view and front view and Figs. 3 8 are vertical longitudinal sections through the wall of the machine for the better illustration of the operation of the sinkers and consecutively corresponding to the section lines af-w to ee-' from r1 ht to left of Figure 1. Fig. 9 illustrates iagrammatically the connection of a jacquard apparatus of ordinary construction with the knitting machine. Fig. l() indicates diagrammatically another construction of the usual knitting lock and Figs. 11 and 11a show respectively side elevation and front view of another modification illustrating the use of a dividing comb employed in place of a jacquard for the raising and lowering of the sinkers.
Broadly speaking, the new feature of the invention as compared with the previous art may be indicated as follows: The two single cylinders P are arranged above each other and are composed of several portions and comprise sliding surfaces or guides D and E along which the draft sinkers G, which are provided with correspondingly inclined surfaces, are adapted to move. By means thereof the sinker G is moved immediately above the operating needle J into a position adapted for the direct engagement or disengagement with the operating needle to be displaced. The pushing sinker F, which is disposed below or adjacent the movable engageable or disengageabledraft sinker G, is
adapted to move with the'latter in the vertical direction. .The pushing sinker may operate directly upon the operating needle, so as to move the same into the central inoperative position indicated in Fig. 2 in which position the securing of the stitches has already taken place. B this means it is possible by the pressure of the weak cards of the jacquard to securely and reliably operate the sinkers for the operation of the'needle. This operation takes place by the direct acoperative position, thread guide Q, needle` tooth o ener R and needle lock S, N the 'upwardy pointing arrows indicating in a conventional manner the operation of the needles in the direction of the arrow. O'n the lefthand side of the drawing at I the sinker and needle bar H isshown mounted in the case C and withthesliding surfaces D and E for the sinkers G. On the righthand side of the drawing at II the sinkers F and G are shown, the draft sinkers being indicated at G and the pushing sinkers at F in their positions of rest with relation tothe sliding surfaces D and E and in the disengaged position.
.The needles controlling locks S are constructed in such amanner that in the operating lock of the lower group of needles the sinkers F and G are adjusted to be constantly operated, while otherwise the arrangement issuch that with the operating lock of the upper grou of needles only the vsinkers F and G are a apted to be engaged with or operated and pulled by the jacquard apparatus, Fig. 9,. oroan e uivalent means, by the cord K -or the lille. 'The 'acquard or other pattern-producing niemr is iexibl connected to the pulling sinker jack but inasmuch as thetwo sinker jacks F and G are in engagement with each other b means of their angularly projecting feetv M the pullin of the sinker jack G will also carry a ong the pushing sinker jack F. A
Now, referring more particularly vto the figures of the drawing which correspond to the second section indicated in Fig. 1, I would say that in Fig. 2 the pushing sinker is indicated enerally at F, while the draft sinker is in 'cated at G, in side view at 1, 1 andvin plan .view at 2, 2, also showing the pushing shoulders T and the pushin lugs. Fi 3 shows the pushing sinker and theraft sinker G 1n side view, correponding to section V-W. o .c ig.-3 shows the position of the-o eratmg needle J and of the lower sinkers and G 1n the position of rest, while the upper sinkers F and G have been pulled by the,
cord K of' the jacquard a paratus or-equivalent -means,'the"dra't si er G b'eing at the same time sitione along the sliding surface's'Daan `Eready for enga ement with theirpperating needle J and int e depressed positlon, whereupon the draft sinker'G israised together with the pushing sinker F.
Fig. v4: is a side view, with parts in section, corgesponding to Vsection X-Y Fig-i1)v wi the sinkers Fand G elevate -byfthe thereby, while the lower draft sinker G,-
being; contrary to the arrangement of the upper sinkers in enga ement with the lower needle-controlling loc as above set forth,
is disengaged from the operating needle J and is engaged by the substantially camshaped lower lock section S.
Fig.v 5 is a side view with parts in section, corresponding to section .AA- BB of Fig. 1, showing the parts in reverse position with relation to Fig. 4, and with the upper sinkers F and G in the 'inoperative position, so as not to be aiiected by the jacquard a paratus, while the lower sinkers F and (gr,
which are controlled as above set forth by the lock S, are adapted to become engaged and pull the o erating needle J. hose of the sinker-jac vin the upper ,cylindrical needle bed which have not been pulled by the jacquard or similar pattern-making member will be operated u on in the usual manner by the cam-like-loc member S, N.
Fig. c6 is a side view with parts in section corresponding to sectional line CC-DD showing the` position of the' sinkers with the operating needle .J -a'- securing the stitches, these stitc es as'seen in the direction" of the arrow being inthe inverted position with relation tothe other stitches thatis to say pearling stitches or j -I osition of stitchesfturned lfor the purpose of forming f a patterni.' L k Fig. 7 shows the n position with relation-'to Fig. 6 and with the operating needle J m the lower cylinder P disposed for the fasiteningl and securing of the stitches.
Fig. 8 is a side view-with parts in'sectionA :corresponding to sectional view 'EE-FF ptas in the inverted of Fig. 1 in which the lower sinkers F and G have already assumed theirv pperative position while the upper sinkers vand G are in the positionv in which the pushing sinker is adapted to push the operating needle in the directiontowards the lower sinkers F and G'so as to restore the parts totheir position of rest.
Fig. 9 shows a well-known jacquard apparatus of conventional manner in side elevation with cords K beingadapted to pull the stitches into the operating position 1n accordance with the position and the configuration ofthe jacquard'-cards.
Fig. 10 illustrates an auxiliary lock section adapted to be employed in a modiiication of my invention-in place of the jacquard The arrangement mal be such that, while r the upper portion of t e machine in which only those sinkers adapted for the working of the pattern are in engagement with the controlling locks of the needles, is called upon to producethe iguring or fancy pattern of the goods, all the sinkers of the lower cylinder bar, as'hereinbefore set forth are in engagement with the lock portion of the particular lower machine section and are arranged to produce the rows or other iigures on which the variation of tension of the fabric depends for producing the reduction or enlarging, similar to the eect hereinbefore obtained by the usual lessening or diminishing of stitches or equivalent means.
Thse rows or stitches may preferably be arrangedin such a manner as to extend in a parallel direction or transversely with relation to the pattern and at the outside or w'ithin the same. The engagement of the pushing and draft sinkers may be such that the draft sinkers or the like in their descent move alon their guides past the'push'ing sinkers an along a corresponding guiding portion of the same, while upon the pulling of the draft sinkers the pushing sinkers become free to drop ast the draft sinkers to be engaged with t e needle in their turn. Within the scope of my invention I also contemplate arrangin the tension lvarious other modifications and alterations to answer other urposes and to suit diierent working con itions,l without thereby deviating from the scope and spirit of my invention as defined in the appended claims.
