METHOD OF KNITTING.
Specification of Letters Patent.
Patented Oct. 1'71, 1916.
Application filed December 22, 1915. Serial No. 68,196.
To all whom it may concern:
Be it known that I, WILLIAM WALL CHAoE, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Method of Knitting, of which the following is a full, clear, and exact description.
Among the principal objects which the present invention has in view are: To control the guide of a knitting machine for localizing the weaving thereof for forming designs having alternate filled and blank spaces; and to form fabric incorporating the design by a knitting machine and by a continuous operation thereof.
Drawings-Figure 1 is a detail view showing on a magnified scale, a fragment of net constructed in accordance with the present invention; Fig. 2 is a view illustrating the arrangement of the interwoven threads, said threads being spread to facilitate the tracing of the same; Figs. 3 and 4 are diagrammatic views illustrating the relative movementof the guide bars employed for laying the threads for the fabric; Fig. 5 is a detail view showing bearing members of guide bars employed by machines when opcrating pursuant to the present invention, and operating cams for shifting the bars when laying the threads guided thereby.
Description-The method herein disclosed is eniployed by me chiefly in the manufacture ofnet, and particularly net wherein the threads are laid to produce a honey-comb as indicated on an enlarged scale in Fig. 1 of the drawings, where the open spaces A are formed by laterally disposed woven bodies B, which are connected diagonally by relatively thinner connecting sections C. When constructing this fabric, 1 preferably employ a machine wherein two guide bars are used, which are laterally shifted and advanced in a horizontal plane, moving in relatively opposite directions, to form similar evolutions, as indicated by the diagrams shown in Figs. 3 and 4. The method may be performed by hand. I prefer, however, to employ a machine wherein the cams 10 move the guide bars laterally, the said guide bars having rollers such as 12 and 13, which ride the edge surfaces of the cams 10 and 11. The guide bars are of conventional construction.
of sources of supply, each source being in- K dependent of all other sources. The fingers 14 are caused to move in the path of needles 15, which are conventionally arranged and reciprocated vertically. These needles are furnished with a suitable crooked end, the opening of. the crook being adapted to pass over the thread furnished by the fingers and to engage the same in the downward movement of the needles to draw the loops, as shown best in Fig. 2 of the drawings. As in the usual knitting machine, each loop is drawn through another loop, the resultant fabric being .a multiplicity of interwoven oops.
When operating the guide bars connected with the rollers 12 and 13, and carrying each a series of fingers 14, they are moved around the needles 15 in the paths indicated by the lines designated by the numerals 16 and 17 and shown in Figs. 3 and 4, respectively. In
each of said figures, the line designated portrays the movement of one finger and the lay of the thread carried thereby for operation upon by three needles 15. The result of the movements of the opposite bars in the paths indicated in the presence of the cooperating needles 15, produces the weave shown in Figs. 2 and 1, respectively.
. To facilitate the description of the method herein desclosed, the needles 15, which, it is understood, are arranged in groups of four, with which groups two fingers 14 cooperate. In Figs. 3 and 4 the numerals 15 indicate identical needles. The lines 16 and 17, however, indicate the paths of and thread laid by the opposed bars and the fingers 14 thereon.
All the stitches forming the particular design herein described are identical, the bars and fingers 14 thereof moving synchronously. Thus from an initial station, designated by the numeral 18 in the drawings, a thread is carried from a position juxtaposed to the first needle of one group, past the middle needle of the same group, to a station juxtaposed to the third needle of the group, and to a point designated by the numeral 19. The guide bar is now shifted,
so that the finger14 and thread carried thereby pass between the middle and third needles of the group, to a position indicated by the ngen:
be observed that the thread at the back of loop 22, as seen in Fig. 2 of the drawings.
To resume the path of the needle as shown in Fig. 3, the thread isnow carried from the position 21 through the station 23 juxtaposed to the middle needle of the group. At this point, the bar is swung back and around the middle'needle to deposit at the back thereof, the thread which this needle engages to form a loop 24. When the guide bar and the finger 14 is brought forward, it is again returned to the posltion 25 juxtaposed to the third needle of the group, from which position it is again returned'back of and around the said third needle, which cooperating therewith forms a loop 26. The finger after coiiperating in the formation of the loop 26, returns 'to the forward position designated by the numeral 27, from which it moves to the positionin front of and juxtaposed to the first of the group of needles, said position being indicated by the numeral 28. From this position, the finger is carried between the first and second needles of the group, and around the first needle to a forward position 29, permitting the first needle to form the loop 30. From the position 29, the finger moves to the position 31 between the first and second'needles, and is carried between the said first and second needles and back of and around the second needle, and brought forward to a position32, permitting said second needle to form the loop 33. The finger and thread is then laterally advanced to the position 34 between the first and second needles to be moved therebetween back ofand around the first needle to the initial station 18, permitting the said first needle to form the loop 35.
The above describes the complete cycle of one finger 14 and thread carried thereby in the presence of three needles. In Fig. 2 of the drawings, it will be noted that the black thread at the left of said figure has been employed to illustrate the movement and lay of the thread and the loops forming the net. The white thread shown in the said figure, is laid by the finger 14 on an opposite guide bar, and the movement of one finger and the thread carried thereby on said guide bar is shown in Fig. 4 of the drawings.
In Fig. 4, the initial station selected is designated by the numeral 36, juxtaposed to the fourth needle, and which corresponds in 'point of time with the station 18 in Fig. 3.
From thissta-tion 36, the finger on the second uide bar moves laterally in a direction opposite that formerly described until the finger is brought to the station 37 in front of the third of the above denoted fgroup of needles. From this position, the nger of the second guide bar passes behind and around the second of the group of needles to permit the. same to form the loop 38. The second finger passes from the forward position indicated as 39, to the position between the second and third needles, from which it is carried back of the third needle andaround the same to permit it to form the loop 40. The needle is then brought'to the forward position 41.
It should now be noted that the loop 22 formed by the cotiperation of the third needle with thefinger of the first-mentioned bar, and'the loop 38 formed by the second needle with the finger of the second-men- I tionedbar, were formed simultaneously, and
that when the loop 24 formed by the cooperation of the finger of the first bar and the second needle, and the loop 40 formed by the third needle and the finger of the second bar, were perfected, they were drawn through the previously formed loops 22 and 38.
From the position 41, the finger of the second bar moves to'a position between the second and third needles, and ispast back of and around the second needle and brought forward to a position indicated by the numeral 42. The first needle then forms the loop 43,-which, it will be noted, by reference to Fig. 20f the drawings, is drawn through the formerly perfected loop 24. 1 From the position 42, the finger of the second bar is now carried to a position 44 between the third and fourth needles of the group from whence it is moved back of and around the fourth needle, and brought forward to a a it is carried back of and around the thirdneedle and brought forward to a position indicated by the numeral 48. Laying the thread-at the back of the third needle permits the same to form a loop 49. From the osition 48, the finger moves to a position '50,
etween the third and fourth needles, from whence it is carried back of and about the fourth needle and brought forward to the, finalposition, thereby forming the loop 51.
It will be noted that the loops 49 and 51 were drawn through the 100 s 38 and 40, respectively. It should also e noted that in the above description and operation of the same has been continued past the complete cycle to form the loops 35 and 51, re-
spectively, which loops in reality form the initial loops of a second cycle of said bars and fingers.
It Will also be noted that the loops 43 and 1 46, and 26 and 30, are connected by relatively long threads or stitches, which, when the fabric is completed, constitute, in part, the connecting sections G. The loops 38, 46, 49 and 40 form the filled sections B of the completed fabric, and the open spaces A are the blanks between the said connecting sections and filled sections.
A process of knitting consisting in first forming a pair of chains of stitches by the employment of a pair of yarns, each yarn forming alternate stitches in the respective chains of said pair, then shifting said yarns from the last formed stitch of each chain laterally to cross said other chain of the pair and thereafter similarly forming other pairs of chains embodying stitches in continuation of the last named chain of said pair and of said laterally shifted yarn.
