  • the cam K is so formed that in the revolution of the wheel it maintains the lever H in the position shown in Fig. 1 or returns it to that position.
  • I provide the following mechanism: Z is aprojection from plate J, which by means of link Z is connected to bell crank lever L, one arm of which has at its end the toepiece Z and below the end the pin Z to which is connected a spring Z", which normally holds the bell-crank L and the plate J in the position shown in Fig.
  • the gear-wheel K is intended to make one revolution for three revolutions of the cam-cylinder, and, as shown, the cam K controls during one-third of the revolution and the cam K" during two-thirds of the revolution when both are acting.
  • the lever H will be acted on to throw the predetermined needles out of action for two revolutions of the camcylinder and in action for one revolution.
  • the lever L is locked in its position after action upon it by the lug M on the pattern-chain by reason of the pivoted latch N, which by gravity engages the pin Z".
  • the latch N is released and the bell-crank L returned to its initial position by the projection N on the pattern-chain M, which strikes the latch N, lifting it, and the spring Z draws the bell-crank L to its initial position, lifting the plate J, bringing the roller J into action only with the cam K, and the cam K will operate the lever H and the plate F to bring the levers E into action.
  • the position of the cam K with reference to the gear K is such as to make it operative, so that the needles will be thrown into action at the proper time.
  • WVith my mechanism in order to arrange which of the needles are to be thrown in and out of action during the formation of the lace or open work it is only necessary to arrange the pattern-plates f and f that is, provide orifices in the plate f corresponding to the tails of the levers E desired to be thus operated and orifices in the plate f corresponding to the tails of the levers E not desired to be then operated.

  • cams K and K are such that in one revolution thereof the cam K acts through two-thirds of the revolution and the cam K one-third and that they are designed to run as one revolution for three revolutions of the cam-cylinder, this may be varied, as it may be desirable to have the needle stitch every second course or only every fourth course, and this would only require a change of extent of rotation and relative revolution of the cams.
  • fashioning-needles,as is well known, in circular-knitting machines are those needles which are used to form the back of the stocking, the heel, toe, and sole. They are termed fashioning-needles because in the formation of the heel and toe their number is gradually reduced course by course until the fabric is narrowed down and then gradually increased course by course until the full number are again in use.
  • fashioning-needles This is called fashioning, and the needles used in this operation are termed fashioning-needles. They comprise one-half of the needles and arein practice placed in the front half of the machine.
  • tuck-stitching upon the fashioning-needles is accomplished in the following manner:
  • Such of the fashioning-needles which I intend to use to form tuck-stitches I form with latches of extra length, so that in the normal position of such needles the regular throw-01f cam of the machine will not in its ordinary position lift the needles high enough to throw off the stitch.
  • These'needles are lettered Z.
  • this throw-0E cam so that it can be elevated to such a level that these tuck-stitch fashioning-needles, as well as the remaining fashioning-needles, will be elevated high enough to throw off the stitch.
  • the throw-off cam in its normal position the fashioning tuck-stitch needles will receive but not cast off a stitch.
  • I also connect the mechanism for lifting this throw-off cam so that it is lifted during rotary work of the machine during the same course that the mechanism to 01)- erate the non-fashioning tuck-stitch needles to throw off their stitches acts.
  • I also provide mechanism which will operate the camlifting mechanism so that the cam is elevated and maintained elevated during reciprocating work of the machine (forming the-heel and toe) and during the formation of the sole.
  • the left-hand switchcam is provided at or near one end with a pin 10, which rests in a horizontal slot 11 in the block 3, so that While still connected as in my Patent No. 521,860 its upper surface will by the vertical movement of the block be elevated or depressed 0., is vertically movable. hen at its lower position, its height is such that in the passage of the needles over it before reaching the stitch-cams 12 the long-latched needles are not elevated sufficiently to throw off the stitch, while the short-latched needles are elevated sufficiently to throw off their stitches. (See Fig. 16.) When the block is elevated, the upper surface of the cam 7 is elevated sufficiently to lift both the long and short latched nee)dles, so as to release the stitch. (See Fig. 15.
  • lever 13 is a lever or plate pivoted at 14 upon a plate 17, secured to the cam-cylinder, and having the projection 15, adapted when the lever 13 is swung to move under and operate upon the cam-face 6 of the block 3 and lift the block.

UNITED STATES HARRY A. HOUSEMAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO STANDARD MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
CIRCULAR-KNITTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 779,423, dated January 10, 1905.
Application filed October 31, 1902. Serial No. 129,521.
T all whom it may concern:
Be it known that I, HARRY A. HoUsnMAN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Circular-Knitting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
The object of my invention is an improved circular knitting machine which will automatically and without stoppage of the machine produce a seamless stocking having a I 5 lace or tuck stitch upon the front of the leg, the instep, and upper portion of the stocking, tuck stitch work upon the rear of the leg, and plain stitches upon the heel, toe, and sole of the foot.
2 In a previous patent issued to me, No. 654,347, dated July 24-, 1900, I have shown, described, and claimed devices so combined in a circular-knitting machine that tuckwork is formed in a seamless stocking upon certain 5 of the needles used to form the front of the leg, the instep, and the top of the foot.
In my present invention I provide, in addition to the above, separate mechanism that will form tuck-stitches upon certain needles 3 used to form the back of the leg of the stocking. The last-mentioned mechanism is automatically and in the operation of the machine thrown out of action during the formation of the heel, toe, and sole, while during the formation of the leg the two tuck-stitch mechanisms operate in unison and uniformly. A circularknitting machine embodying my improvements will knit a stocking such, for instance, as is shown and described in Letters 4 Patent of the United States No. 702,843 in the continuous operation of the machine.
For the general construction of the circular-knitting machine to which my improvements have been added reference may be had to Letters Patent No. 538,518, issued to me April 30, 1895.
In the drawings, Figure 1 is a side elevation of a part of my improved knitting-machine. Fig. 2 is a side elevation of the operating-cam and its driving mechanism. Fig. 3 5 is a plan view of the same. Fig. 4: is a plan view of pattern-plates. Fig. 5 is a side elevation of the machine. Fig. 6 is a section through a portion of the cylinder, showing the operating-levers and their connections. Fig. 7 is an enlarged side elevation of portion of machine.

' The machine of Patent No. 538,518, as is Well known, consists of an operating-cam cylinder A, which is driven by the gear B upon the shaft Z), which shaft 7) is rotated by means of the bevel-gear c on the driving-shaft D, meshing with the gear 0 loose upon the shaft 5 andreciprocated by means of the gear D, 8 5 also loose upon the shaft 5, operated by the rack D By means of the clutch D feathered upon the shaft 6, the shaft 6 is connected with either the rotary gear 0 or reciprocating gear D, and thus the cam-cylinder rotated or reciprocated. The needles are held in levers E and E The levers E control those needles which in the manufacture of circular goods, such as stockings, are during the formation of the heel and toe thrown out of action. In the operation of this machine, as is fully set out in the Patent No. 538,518, last mentioned, before the levers E are at the desired point in the knitting they are automatically oper ated upon to throw them out of action bya plate F, in which the tails of the levers E rest, the plate having depending rodsf, which are operated upon by mechanism described in said patent to move the rods and plate. In order to operate upon the desired number of levers E and their corresponding needles to throw certain of the needles in and out of action for predetermined rotation of the camcylinder, and thus form the tuck-stitch, I add the following mechanism to this part of the machine:
I make my levers E with bifurcated ends a c. The plate F is formed with a cut-away portion f, beveled at its lower surface f in which the end rests. Upon the top of this plate F is a pattern-platef, removably secured thereto and which projects into the space between the ends 0 e of levers E. In this plate f corresponding to the levers desired to be acted upon in the formation of the open or lace work of the fabric, are orifices f of a size sufiicient to allow the tail 6 of lever E to pass up through them. For the rods f, connected to the plate F, I use tubes. Superimposed upon the pattern-plate f 3 is a second pattern-plate f removably secured to the plate F. The plate F has a cut-away portion in which the end a of lever E rests. The pattern-plate f has a portion which projects into the space between the ends 0 e of the levers E, and the thickness of the plates f f is equal to the space between said ends.
The upper surface of this plate f is beveled. In this pattern-plate f corresponding to the levers which are not desired to be acted upon in the formation of the open or lace work of the fabric, are cut-away portions f of a size sufficient to allow the tails e of the levers E to pass through. Secured to the plate F by nuts f" are the rods f and f", which pass through orilices in the patternplates f and f and plate F and through the tubes f. The lower end of rod f passes into an orifice g in the lever Gr, and by means of a nut g the vertical height of the rod f may be adjusted. This lever G is secured to the rock-shaft G. The lower end of rod f 9 is correspondingly secured to a lever G which is also secured to the rock-shaft Gr. The end of lever G opposite the shaft G has upon it the cam-plate Upon the rods f 7 and f are the springs f H is a lever pivoted to the frame of the machine at it and having at one end the camplate It, adapted to operate the camplate g When the lever Gris in the position shown in Fig. 1, the rods f f" are lowered and the needles acted on by the plate F are in action. When the plate F is moved to the position shown in Fig. 6, the cam-plate operates on the cam-plate and through it upon the lever G, lifting the rods f f" and elevating plate F and certain of the needle-levers E, throwing those needle-levers and their needles out of action. I operate this lever H as follows: j j" are pins upon the lever H below the pivotpoint h. J is a superposed plate having a roller J at its lower end and slots j j through which the pins jj project. K K are two cams secured upon the face of the gear-wheel K. The cam K projects from the face of the gear-wheel a greater distance than does cam K The roller J is normally in such position that it rests against the cam K at a point above the cam K The cam K is so formed that in the revolution of the wheel it maintains the lever H in the position shown in Fig. 1 or returns it to that position. In order to bring the roller J under the influence of both cams K and K and remove it from such influence, I provide the following mechanism: Z is aprojection from plate J, which by means of link Z is connected to bell crank lever L, one arm of which has at its end the toepiece Z and below the end the pin Z to which is connected a spring Z", which normally holds the bell-crank L and the plate J in the position shown in Fig. l in contact only with the cam K. In this position the toe-piece Z is in line with a pattern-chain M upon the shaft on. Upon this chain is the lug lV This lug in its movement strikes the toe-piece Z moving the bell-crank L against the action of the spring Z, depressing the plate J and bringing the roller J into operative relation with both cams K and K at different portions of the gearwheel K.
In the specific illustration shown in the drawings the gear-wheel K is intended to make one revolution for three revolutions of the cam-cylinder, and, as shown, the cam K controls during one-third of the revolution and the cam K" during two-thirds of the revolution when both are acting. Thus when the bellcrank has been acted on by the lug on the pattern-chain, as just described, the lever H will be acted on to throw the predetermined needles out of action for two revolutions of the camcylinder and in action for one revolution. The lever L is locked in its position after action upon it by the lug M on the pattern-chain by reason of the pivoted latch N, which by gravity engages the pin Z". The latch N is released and the bell-crank L returned to its initial position by the projection N on the pattern-chain M, which strikes the latch N, lifting it, and the spring Z draws the bell-crank L to its initial position, lifting the plate J, bringing the roller J into action only with the cam K, and the cam K will operate the lever H and the plate F to bring the levers E into action. The position of the cam K with reference to the gear K is such as to make it operative, so that the needles will be thrown into action at the proper time. WVith my mechanism in order to arrange which of the needles are to be thrown in and out of action during the formation of the lace or open work it is only necessary to arrange the pattern-plates f and f that is, provide orifices in the plate f corresponding to the tails of the levers E desired to be thus operated and orifices in the plate f corresponding to the tails of the levers E not desired to be then operated. By having a series of these plates with orifices at different points change of pattern may be obtained by merely changing the patternplates. While I have described the cams K and K as being such that in one revolution thereof the cam K acts through two-thirds of the revolution and the cam K one-third and that they are designed to run as one revolution for three revolutions of the cam-cylinder, this may be varied, as it may be desirable to have the needle stitch every second course or only every fourth course, and this would only require a change of extent of rotation and relative revolution of the cams.
The preceding description relates to that part ofthe machine which is used to form the lacework upon the front of the stocking and with the needles which are thrown out of action during the formation of the heel and toe and which is disclosed in Patent No. 654,347. I will now describe the additional features over those of the last-mentioned patent and which form the subject-matter of the present invention. The particular object of these additional features or devices is to provide tuck-stitching upon certain fashioning-needles Z Z during the formation of leg of the stocking, and thus form a tuck-stitch all around the leg of the stocking and yet have no tuckstitching upon these needles during the formation of the heel, toe, and sole. Further, I so connect the tuck-stitching mechanism of these fashioning-needles with the tuck-stitching mechanism of the non-fashioning needles, before described, that when the tuck-stitching mechanism of the fashioning-needles is in operation the tuck-stitching will be uniform throughout. The fashioning-needles,as is well known, in circular-knitting machines are those needles which are used to form the back of the stocking, the heel, toe, and sole. They are termed fashioning-needles because in the formation of the heel and toe their number is gradually reduced course by course until the fabric is narrowed down and then gradually increased course by course until the full number are again in use. This is called fashioning, and the needles used in this operation are termed fashioning-needles. They comprise one-half of the needles and arein practice placed in the front half of the machine. Speaking generally, the tuck-stitching upon the fashioning-needles is accomplished in the following manner: Such of the fashioning-needles which I intend to use to form tuck-stitches I form with latches of extra length, so that in the normal position of such needles the regular throw-01f cam of the machine will not in its ordinary position lift the needles high enough to throw off the stitch. These'needles are lettered Z. I also arrange this throw-0E cam so that it can be elevated to such a level that these tuck-stitch fashioning-needles, as well as the remaining fashioning-needles, will be elevated high enough to throw off the stitch. Thus it may be seen that with the throw-off cam in its normal position the fashioning tuck-stitch needles will receive but not cast off a stitch. I also provide mechanism or devices for lifting the regular throw-off cam to a level or height that will throw off the stitches upon the fashioning tuck-stitch needles. I also connect the mechanism for lifting this throw-off cam so that it is lifted during rotary work of the machine during the same course that the mechanism to 01)- erate the non-fashioning tuck-stitch needles to throw off their stitches acts. I also provide mechanism which will operate the camlifting mechanism so that the cam is elevated and maintained elevated during reciprocating work of the machine (forming the-heel and toe) and during the formation of the sole.
I will now describe the specific mechanism illustrated in the drawings for accomplishing the above purposes. The wall of the camcylinder A is cut away, forming the slot having the projecting tongues 2. In this slot rests the block 3, having the vertical slots I, in which rest the tongues 2. Between the top of the block 3 and the under surface of the top of the cam-cylinder is the spring 5, tending to hold the block at its lower point. The block has the projecting cam-face 6, which projects outwardly beyond the cam-cylinder.
The stitch-cams of my machine, speaking generally, are shown in Letters Patent No. 521,860, dated June 26, 1894, granted to me. As shown in that patent and in the drawings illustrating my present invention, I use as a part of the stitch-cams the switch-cams 7, each of which normally rests against a corresponding stitch-cam 12. As in my previous patent mentioned, each of these switch-cams 7 has a pin 8 secured to it, which pin rests in an orifice 8 in the cam-cylinder, and a springactuated pin 8 bears against said pin 8. The function of these switch-cams 7 of the stitchcams is in ordinary knitting both reciprocation and rotation to determine the direction of the travel of the needle, whether above or below the stitch-cam 12. Its operation is clearly described in my previous patent spoken of and may be stated here as follows: The movement of the cam-cylinder causes a switchcam 7 to strike a needle. If it is the upper surface of this switch-cam which strikes the needle, the needle follows that surface toward the top of the stitch-cam 12. If it is the under surface of the switch-cam 7 which strikes, the needle lifts the switch-cam at that point, allowing the needle to pass. In the present machine the function of these switch-cams, so
far as the purpose heretofore described is concerned, is the same as in the previous patent mentioned.
In my improved construction in addition to the above one of the switch-camsas shown, the left-hand switchcamis provided at or near one end with a pin 10, which rests in a horizontal slot 11 in the block 3, so that While still connected as in my Patent No. 521,860 its upper surface will by the vertical movement of the block be elevated or depressed 0., is vertically movable. hen at its lower position, its height is such that in the passage of the needles over it before reaching the stitch-cams 12 the long-latched needles are not elevated sufficiently to throw off the stitch, while the short-latched needles are elevated sufficiently to throw off their stitches. (See Fig. 16.) When the block is elevated, the upper surface of the cam 7 is elevated sufficiently to lift both the long and short latched nee)dles, so as to release the stitch. (See Fig. 15.
13 is a lever or plate pivoted at 14 upon a plate 17, secured to the cam-cylinder, and having the projection 15, adapted when the lever 13 is swung to move under and operate upon the cam-face 6 of the block 3 and lift the block. This lever or plate 13 has also the projecting portion 15. The plate or lever 13 is also pivoted at 13 to a second plate or lever 16, which latter lover is also pivoted at 16 to the plate 17; but the plate or lever 13 is at a higher level than the plate or lever 16. The plate or lever 16 has also a projecting portion 18. Secured loosely upon, so as to be movable around the upright 19, is the arm 20, held in frictional contact therewith by the pin 20. The outer end of this arm is provided with the cam-face or operating-cam 21.
22 is a frame secured to the upright 23 and loosely surrounding the upright 19. In a projection 24 from frame 22 is the set-screw 25, and a spring 26 connects the arm 20 and frame 22. By lifting either upright 19 or 23 the arm 20 is lifted. hen it is lifted, the camface 21 is in line with the projecting portion 15 of the lever 13 and in the rotation of the canrcylinder is acted on to lift the block 3 and the cam 7 to a position to throw off the stitch on both the long and short latched fashioning-needles. When the uprights 19 and 23 are down, the cam-face 21 is in line with the projection 18 .of lever 16, which by the previous action has been moved into such alinement, and in the rotation of the cam-cylinder moves said lever and through it the lever 13, releasing the block 3, which by the action of its spring returns to its low position, bringing the switch-cam 7 to the low position, where only the short-latched needles of the fashioning-needles cast their stitch. (See Figs. 8 and 9.) The upright 19 is supported and guided so as to be movable and is provided with the spring 27, tending to hold it in its lower position. The end of this upright 19 rests upon one end of the pivoted frame 28, the other end of the frame 28 being connected to a connecting-rod 29, which in turn is connected to the crank 29 upon the shaft G. The upright 23 is also guided so as to have avertical movement. The lower end of this upright has the collar 30, which is provided with the projection'31, under which one end 32 of the pivoted gravity dog or catch 33 is adapted to rest. This dog or catch 33 has the cut-away portion 34.
36 is the frame to which the shifting-rods 37 for the clutch D are connected. This frame 36 is connected to the upright 38, operated by the clutch-shifting cam 39 and frame 46, all as in Patent No. 538,518, heretofore referred to, and for shifting the clutch to change the connection of the cam-cylinder from rotation to reciprocation. Projecting from and connected to the frame 36 is arm 41, having at its upper end the lateral projection 42 and the vertical projection 43. Upon the lower end of the upright 23 is the projection 44, having the tailpiece 45. The cutaway portion 34 of the catch 33 is in line of movement of projection 43 and the projection 44 in line of movement of lateral projection 42. The pattern-chain M has also upon it the lug 50. The revolution of pattern-chain is so timed and the lug 50 so arranged upon it that the lug strikes the tailpiece 45 at the time the body of the foot is being formed.
' From the foregoing the operation of the machine may be'readily understood. WVhen the leg of the stocking is started to be formed, the uprights 19 and 23 are both down (see Fig. 7) and the lever 13 free from the block 3 and the switch-cam down, so that the long-latched fashioning-needles will not lose their stitch. During the rotation of the cylinder forming the leg at each time the rock-shaft G is operated to throw off the stitch upon the tuckstitch needles of the non-fashioning needles, as before described, the upright 19 is lifted by means of the frame 28 and connecting-rod 29. The elevation of the upright 19 has no effect upon upright 23, but lifts the arm 20, so that the cam-face 21 is in line with the projection 15 of lever 13. and when in the retation of the machine it is struck by said lever the lever turns, lifting the block 3 and bringing the switch-cam 7 to the high level, so as to throw off the stitches upon both the short and the long latch fashioning-needles. (See Fig. 15.) WVhen the upright 19 descends, due to the downward movement of the frame 28 imparted by the connecting-rod 29 and the rock-shaft G, the cam-face 21 is brought in line with the projection 18 of lever 16, and when struck by said projection the lever 13 is moved to bring the end free from the block 3 and the block by the action of its spring descends and the cam 7 is brought to the low point, so that the long-latch fashioning-nee- IOf IIC
IIC
dles take the thread but do not cast the stitch, while the short-latched fashioning-needles both take and cast the stitch. (See Fig. 16.) When the clutch-shifting cam 39 is operated to shift the connection of the cam-cylinder from the rotary mechanism to the reciprocating mechanism, (forming the heel or toe,) the arm 41 is lifted, bringing the projection 42 against the projection 44, lifting the upright 23 and through it the upright 19, bringing the cam 21 in alinement with the projection 15 of lever 15, thus forcing the cam 7 to its high point, Where all the fashioning-needles will cast the stitches. The movement of the arm 41 also moves the vertical projection 43 against the cut-away portion 34 of catch 33, holding the catch out. This position is maintained during the entire reciprocation, and thus during this period none of the fashion,- ing-needles form tuck-stitches. When the shift of the cam 39 is made to change the camcylinder-operating mechanism from reciprocation to rotation, the arm 41 descends, releasing the upright 23, which will then descend and bring the cam 21 in alinement with the projection 18 of lever 16, releasing the block and bringing the cam 7 to its low point. If, however, this last-mentioned shift from reciprocation of the cam-cylinder to rotation be for the formation of the foot, the lug 50 on the pattern-chain strikes the tailpiece 45, the upright 23 is lifted or held lifted, and the catch 33 holds it there until the shift is made again to and from reciprocation. Thus by this construction the tuck-stitching upon the fashioning-needles during the formation of the leg of the stocking is formed corresponding to that formed upon the non fashioning needles. Again, where the fashioning-needles are used in the formation of the heel or toe or sole of the foot tuck-stitches are formed upon none of them. The reason for pivoting the arm carrying the cam 21 and making it freely yielding in one direction is that it will yield if for any reason during the reciprocation of the machine it should be struck.
