ATTACHMENT FOR KNITTING-MACHINES.
SPECIFICATION forming part of Letters Application filed April 22, 1903 To all Ll/77107721 it may concern.-
Be it known that 1, JOHN B. HIPWELL, a citizen of the United States, residing in'the city and county of Philadelphia,State of Penn- 5 sylvania, have invented a new and useful Improvement in Attachments for Knitting-Machines, of which the following is a specification.
My invention consists of means whereby lo the foot portion of a stocking is knit in two colors in such a manner that one of the colors is in the upper part'of the foot of a stocking and the other color isin the lower part thereof.
It also consists of means whereby certain of the loops in the upper half of the foot portion of a stocking are interlocked with certain of the loops in the lower half ofthe foot portion during the process of knitting and in such a manner that no seam exists where such interlocking of the loops occur, thereby pro: ducing a stocking in the foot portion of which two colors of yarn are used and so arranged relatively to each other that one color is in the upper part of the foot portion and the 2 5 other color in the lower part thereof.
Figure 1 represents a partial side elevation and partialvertical section-of a portion of a knitting-machine with certain portions of my improvements applied thereto. Fig. 2 reprego sents a plan view of certain of the parts seen in Fig. 1. Fig. 3 represents a vertical section on line 00 00, Fig. 2. Fig. 4 represents a perspective view of certain detached portions of the device. Figs. 5, 7, and 9 represent elethe machine opened out or developed. Fig. 6 represents a vertical section on line y y, Fig. 5. Fig. 8 represents a vertical section of certain detached portions of the ma- 0 chine. Fig. 10 represents a vertical section of certain detached portions of the machine. Fig. 11 represents a vertical section on line a 2, Fig. 9. Figs. 12 and 13 represent plan views of certain detached 'portions'of the ma- 5 chine. Fig. 14 represents a plan view of the needle-cylinder. Figs. 15 and 16 represent side elevations of needles employed in connection with my invention herein referred to.
Fig. 17 represents an elevation of the inte- Patent No. 733,964, dated July 21, 1903.
Serial No. 153,733. (No model.)
rior of a portion of a cam-cylinder with cer- 5o tain parts somewhat modified from similar parts seen in Fig. 5. Fig. 18 represents a vertical section on line to w in Fig. 17. Fig. 19 represents a partial plan view and partial horizontal section of certain of the parts seen in Fig. 18.
Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings, l designates a cam-cylinderofiusualconstruction and driven by any well-known mechanism, it being noted that the cam-cylinder 1 is provided with the yarn-guides 2 and 3, which are pivoted at 4 and 5, respectively, in the standards 6, which latter rise from the cam-cylinder 1, as seen in Fig. 1.
Projecting radially from the cam-cylinder 1 is a stud 7, on which is loosely fitted the sleeve 8, whose outer end is provided with the inclined faces 9, so as to produce a wedgeshaped extremity which is adapted to enter at certain times the recess 10 in the collar 11, which is loosely fitted on the stud 7 and is adapted to slide thereon for a purpose hereinafter described. The collar 11 is provided Y with the projecting members 12 and 13, through the outer ends of which are passed one end of the rods 14 and 15, respectively, as seen in Fig. 1. The inner ends of the rods 14 and 15 are provided with the cams 16 and 17, respectively, and as best seen in Figs. 5, 10, and 11. The rods 14 and 15 are loosely fitted in guides 18, secured to the cam-cylinder 1, as best seenin Fig. 1, it being noted that said rods 14 and 15 are provided with springs 19, the object of which is hereinafter described, and, furthermore, that the sleeve 8 is provided with an arm 20, whereby said sleeve 8 may be turned on the stud 7 when desired.
Rigidly secured to the cam-cylinder 1 are cams 21, 22, 23, 24, 25, and' 26 of usual construction.
Secured to the cam-cylinde-r"1 are guides 27 and 28, (see Fig. 2,) in which are guided 95 the rods 29 and 30, respectively, itbeing noted that the rod 29 is provided at its inner end with the cam 31, which passes through an opening 32 in the cylinder 1, and that the rod is provided at its inner end with the cam 33, which passes through an opening 34 in the cam-cylinder 1, and, furthermore, that the cams 16 and 17 pass through openings and 36, respectively, in the cam-cylinder 1. The rods 29 and 30 are each provided with a collar 37, the inner end of each of which isin the shape of a wedge 38, which is adapted to enter its respective recess 39 in the guides 27 and 28 for a purpose hereinafter described, it being noted that the rods 29 and 30 are each provided with a spring 40, the object of which is hereinafter described.
Located Within the cam-cylinder 1 is the needle-cylinder 41, of ordinary construction, and is supplied with needles 42, which are provided with hubs or butts 43, which are longer than the hubs 45 on the needles 44. (See Figs. 1, 8, 10, 14, 15, and 16.)
The operation is as follows: Assuming that the leg and heel of a stocking are finished and that the foot portion is to be produced, the same is accomplished by bringing into action the yarn-guide 3 from the position seen in dotted lines in Fig. 1 to that seen in full lines in said figure, after which the yarn 47 is connected with the stocking in the machine, which was previously" stopped. The arm 20 is then operated by any suitable mechanism and causes the sleeve 8 to turn upon the stud 7 in order to bring the wedge-shaped portion 9 of said sleeve 20 in alinement with the recess 10, whereupon the springs 19 expand and in doing this move the rods 14 and 15, and consequently the cams 16 and 17 thereon, inwardly, thereby causing said cams 16 and 17 to project within the cam-cylinder 1, as seen in Figs. 10 and 13, it being understood that when the cams 16 and 17 are in their normal or not-working positions they do not project within the cam-cylinder 1 and are in the positions seen in Figs. 2, 3, and 11. The sleeves 37 are then turned upon the rods 29 and 30, so as to cause their Wedge-shaped portions 38 to register with the recesses 39, whereupon the springs 40 expand and cause the rods 29 and 30, and consequently the cams 31 and 33 thereon, to move inwardly, and thereby bring said cams into action by causing the same to project within the camcylinder 1, as seen in Figs. 8 and 12, it being understood that when the cams 31 and 33 are in their normal or inoperative position they do not project within the cam-cylinder 1, as seen in Figs. 2 and 6. After the cams 16, 17, 31, and 33 are brought into their operative positions, as just stated, the machine is again started, so as to impart motion to the camcylinder 1 and rotate the same to the extent of one revolution in one direction and then in the opposite direction and to a similar extent, and this reciprocating rotary motion of the cam-cylinder 1 is continued until the foot portion of a stocking is finished, after which the toe portion thereof is made. Assuming the yarn 46 to be black and the yarn 47 white and that the camcylinder 1 is rotating in the direction indicated by the arrows ain Fig. 5, the needles 42 and 44 are then operated in the following manner, it being understood that the hubs 'or butts 45 are not of sufficient length to be engaged by the cams 16, 17, 31, and 33, although they are of sufficient length to be engaged by the cams 22, 23, 24, 25, and 26: The needles 42 follow the course indicated by the arrows *c in Fig. 5 when the cam-cylinder 1 is rotating in the direction indicated by the arrows at, whereupon said needles 42 are supplied with one color of yarn and knit the same into the upper half of the foot portion of a stocking when depressed by the cams 31 and 24. When the cam-cylinder 1 is reversedthat is to say, when it is rotating in the direction indicated by the arrows b in'Fig. 9the needles 42 will follow the course indicated by the arrows d in said figure, after which they again follow the course indicated by the arrows c in Fig. 5, and so on. As hereinbefore stated, the hubs 'or butts 45 do not reach the cams 16, 17, 31, and 33, whereupon it is apparent that when the cam-cylinder 1 is rotating in the direction indicated by the arrows (t in Figs. 5 and 7 the needles 44 will follow the course indicated by the arrows e in Fig. 7, it being understood that the hubs or butts 45 are, as hereinbefore stated, acted upon by the cams 24, 25, and 26, whereupon the needles 44 are supplied with white yarn when the same are in their elevated positions, and when they are depressed by the cams 25 and 26 they knit said white yarn into the lower half of the foot portion of a stocking. When the cam-cylinder 1 is reversedthat is to say, when it is rotated in the direction indicated by the arrows b in Fig. 9-the nee-v dles 44 follow the course indicated by the arrows (1, except where they branch off, as indicated by the arrows f indotted lines, after which they again follow the course indicated by the arrows c in Fig. 7, and so on until the foot portion of a stocking is completed, after which the toe portion thereof is finished in the usual manner.
In Fig. 17 1 illustrate a modification of certain of the parts seen in Fig. 5, said modification consisting in rigidly securing the cams 48 and 49 to the cam-cylinder 1 instead of having them movable,as are the cams 16 and 17, and, furthermore, in making the cam 50 a movable one instead of a rigid one, as is the cam 21, it being noted that the mechanism employed for operating the cam 50 is identical with that employed for operating the cams 31 and 32.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a knitting-machine provided with a cam-ring having stitch-forming mechanism and a needle-cylinder with two sets of needles, one set being provided with long hubs and the other with short hubs, the two sets TIO being arranged on opposite sides of the cylinder but'overlapping one or more needles at each side; an auxiliary stitch-forming mechanism to codperate only with the needles having long hubs, and means for throwing the same into and out of action a pair of inclined cams movably mounted in said cam-ring in operative relation to the main stitch-forming mechanism for the purpose specified, and means for throwing them into and out of action.
2. In a knitting-machine provided with a needle-cylinder and a cam-ring having stitchforming mechanism, the cylinder having two sets of needles, one set having long hubs and the other having short hubs, the two sets being arranged on opposite sides of the cylin der but overlappingione or more needles on each side; an auxiliary pair of stitch-cams rigidly mounted in the cam-cylinder and not as thick as the regular stitch-cams; a movable center cam in the cam-ring cooperating with said auxiliary pair of stitch-cams; means for throwing the same into and out of action, and two movable inclined cams in operative relation with the main stitch-forming mechanism for the purpose specified.
