CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 465,938, dated December 29, 18 91.

Application filed October 2, 1891. Serial No, 407,512; (No model.)

To all whom it may concern.-

Be it known that I, FRANK MALsOH, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia an d State of Pennsylvania, have invented certain new and useful Improvements in Circular-Knittin g Machines, of which the followin is a specification.

In knitting certain articlesfor' example, the heels or toes of socks or stockings or the breast-pockets of ladies under-vests-it is customary to shapeor fashion the article by narrowing or widening the web during the process of its manufacture and according to the requirements of the article being knit. This result is usually accomplished by dividing the needles of the maehine'into two sets or divisions and throwing one of these sets or divisions out of orinto action, and then throwing certain of the needles constituting the other set into or out of action, thus narrowing or widening the web during its formation. The present invention relates in general to knitting-machines, and more particularly to simple, durable, and efficient mechanism for automatically controlling the operation of the needles as well as to certain improvements in the construction and arrangement of the devices for clamping the needle-cylinder to place.

The principal objects of the present invention are, first, to provide a knitting-machine in which the operationsof throwing certain of the needles successively out of or into action are automatically controlled and regulated by the needles previously thrown out of hi into acti n; second, to provide simple, durable, and efficient mechanism for throwing one set or division of the needles collectively out of action in order to permit of the accomplishment of the operations of narrowing and widening the web being formed by the other set or division of the needles; third, to provide positivelyoperated mechanism for automatically and successively throwing certain of the needles out of or. into action in order to accomplish the operation of narrowing or widening the web during its forma- ;.tion, fourth, to provide comparatively inexpensive means for retaining the bits of the needles that are thrown out of action in proper posit-ion for engagement by the automatic needle-controlling mechanism, and, fifth, to provide convenient devices for permitting of the adj ustm'ent of the needle-cylinder and for clamping and unclamping thesame.

My invention consists of a knitting-machine provided with needles, a needle or operating cam, a traveler normally engaging with the hubs or bits of the needles previously thrown out of range of said cam, a finger engaging successively the hubs or bits of the needles in range of said cam, and means connected with. said finger and traveler and operating at the release of the latter to cause out of range of-v the cam.

My invention further consists of a knittingmachine provided with needles, a needle or operating cam, a traveler normally engaging with the hubs or bits'of the needles in range of said cam, a hammer engaging singly the hubs or bits of the needles out of range of said cam, and means connected with said hammer and traveler and operating when the traveler engages the needles to cause the former to throw the needles singly into operative position.

My invention further consists of a knittingmachine provided with a bed-plate, a movable ring having a crown-cam, a needle-cylinder having a crown-cam, and a clamping device interposed between said bed-plate anti cylinder and comprising a recess, a wedge, and an operating-lever.

My invention further consistsof aknittingmachine provided with needles, ,aneedlecylinder, a cam-cylinder, and a sectional ring having the parts thereof united by hinge and screw connections and interposed between said cylinders above the needle-bits.

My invention further consists in the improvements hereinafter fully described and claimed.

The nature and characteristic features of the present invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof, and in which Figure 1 is an elevation on the line :0 0c of Fig. 2, showing a knitting-machine having a sectional ring interposed between the needle and cam cylinders for limiting the range of motion of the needles in an upward directhe former to throw the needles successively too tion and also showing at the left-hand side thereof a carrier provided with stems or rods adapted to engage the shanks of certain of the needles in order to shift them collectively out of range of the operating-cam. Fig. 2 is a top or plan View of a knitting-machine showing two systems of needle-operating levers embodying features of my invention in application thereto. Fig. 3 is a development of the interior of the cam-cylinder, showing two sets of travelers, fingers, hammers, and two systems of spring-controlled levers or links connecting the fingers with one set of travelers and the hammers with the other set of travelers. Fig. 4 is an elevation of a knitting-machine showing a side View of two systems of levers embodying features of my invention, and Fig. 5 is a detail View on an enlarged scale, showing the devices for clam ping the needle-cylinder in position.

In the drawings, A is the bed-plate of a knitting-machine provided with a rotatable ring a, havingcrown-cams ct engaging crowncams on the needle-cylinder, by means of which the needle-cylinder B is adjusted up and down, and with circular ways a for the reception of the cam-cylinder O.

D are knitting-needles adapted to work in suitable axiall -disposed recesses Z2, formed upon the needle-cylinder B, and provided, re spectively, with bits or hubs cl for normally engaging the operating-cams upon the interior face of the cam-cylinder C.

b is a spring fitted into a groove at or near the top of the needle-cylinder B and adapted to retain the needles D in the respective recesses b in such manner that the needles may be shifted up and down vertically by the opcrating-cams in order to perform theoperation of knitting in the ordinary or in an y preferred manner.

Referring now more particularly to Figs. 1 and 4, a is a bracket depending from the under side of the bed-plate A, and adapted to support a collar a in such manner that the latter may be shifted up and down thereon. a is a carrier attached to or formed integral with the collar a and provided with stems or rods (1 projecting into certain of the recesses 19, so that when the carrier a is shifted upward the rods or stems to engage the lower extremities of certain of the needles and thus cause the needles themselves to be shifted upward, as shown at the left-hand side of Fig. 1, out of range of the operating-cams E. b is a sectional ring provided with a flange b and having the parts thereof united by a hinge-joint b and removable screw b so that the ring may be readily placed in position upon or removed from the cylinder B in order to remove or insert the needles or for any other purposes. The ring b itself is fitted into an annular groove formed upon the exterior of the needle-cylinder, so that portions of the ring in eflfect form projections that lie in the recesses of the needle-cylinder and are engaged by the bits of the needles when the same are elevated and are out of action, and the flange b" of the ring b serves a purpose tobe presently described'and also protects the interior working parts of the machine from dust. a is a hand-lever pivoted upon the bed-plate Aand having one extremity extended through a slot in the bed-plate and connected with the collar a by a slotted connection a so that the carrier a may be shifted upward in order to throw certain of the needles out of action or downward in order to permit these needles to be returned manually to operative position. The object in throwing certain of the needles out of or into action is to permit of the accomplishment of the operations of narrowing or widening the web during its formation, so that the number of needles that are collectively thrown out of action by means of the carrier (L5 will vary in different instances, and in all instances there will be one stem or rod a for each needle D that is to be thrown out of action by the carrier In the present instance thirty-six stems are shown, so that thirty-six needles, or one-half of all the needles of the machine, may be thrown collectively out of action by means of the hand-lever (L7.

Referring now to Figs. 1 and 5, (t are lugs projecting upward from the bedplate A and working in grooves b in the needle-cylinder B, in order to prevent accidental rotation of the latter. lhe needle-cylinder B may be adjusted up and down in the usual mannerthat is, by rotating the ring a in one direction or the other by means of a handle attached to the lower face of the ring and working in a recess in the bed-plate and operated from the exterior of the machine. Such a handle is well known and common in circular-knitting machines, and hence is not shown upon the drawings. The rotation of the ring a causes the cams a to be shifted with reference to each other, and the wedge-like shape of the working-surfaces of these cams effects the required movements of the needle-cylinder. After the needle-cylinder B has been adjusted upward or downward by means of the cams a, and in the manner hereinabove described, it may be clamped in place by means of a lever a connected with the baseplate A and provided at its upper extremity with a pivotal jaw a adapted to engage the inclined side wall b of a recess 1), cut or otherwise formed in the needle-cylinder, so that the needle-cylinder B may be adjusted up and down by means of the ring a and then clamped to place by means of the operatinglever a In the drawings only one operating-lever a provided with a movable jaw a, is shown; but it must be understood that more than one such operating-lever and its accessories may be employed.

In the ordinary operation of a knitting machine certain of the needles D-for example, the twelve needles located diametrically opposite the bracket a that is between the lines 2 2 and 3 in Fig. 2'are not thrown.

out of action, and the widening and narrowing operations are performed upon the two sets of needlesbetween the lines 1 1 and 2 2 and 1 1 and 3 3, Fig. 2, which are thrown singly and successively out of action, beginning with the needles nearest the line 1 1 and proceeding in the following order, first, a needle on one side of the machinefor example, the left side-and then a needle on the otherside of the machine, the right side, and so on until all the needles of these two sets of needles are out of action and only the twelve needles between the lines 2 2 and 3 3 in Fig. 2 remain in action. In widening the web the same needles are thrown into action singly and in a reverse manner.

Referring now to Fig. 3, e, e, and e are the ordinary cams for engaging the hubs or bits of the needles. e e e and e are auxiliary cams located upon the interior of the camcylinder 0, and disposed upon opposite sides of the heart-shaped cam e. The auxiliary cams e and c serve to transfer needlebits from near the upper portion of the cam-cylinder G into range of the cam 6 and the auxiliary cams e and e serve to transfer the needle-bits from the cam e to positions near the upper portion of the cam-cylinder 0. Of course the needle-bits are ordinarily out of range of all the auxiliary cams, but are shifted into range thereof by means of mechanism presently to be described. It may be remarked that the bits or hubs of the needles in operative position rest normally upon the upper edge of the portion 6 of the knittingcams E, and the bits of the needles that are out of action rest normally upon the ring b In throwing needles out of action use is made of the following mechanism:

1' are fingers located upon opposite sides of the cams e 6 and provided respectively with curved extremities t" and 11 The extremities 'i' of these fingers are shifted in a manner to be presently described into cavities 2' formed in the top surface of the cam 6 and thus are caused to engage a needle-bit d, as shown at the right-hand side of Fig. 3. Subsequently the fingers t' are shifted into the position shown at the left-hand side of Fig. 3, so that the rotation of the cam-cylinder 0 causes the needle-bits cl to travel along the upper, surfaces of the fingers 1' into range of the cams e and c and these latter direct the needlebits into contact with the ring 12 as shown in Fig. 3, and consequently out of range of the knitting-cams. The movements of the fingers t'are controlled and regulated by means of travelers 2' adapted to slide under the bits (1 of the needlesD that are in contact with the ring b which in most instances includes all the needles previously thrown out of action by the carrier as, plus the needles previously thrown out of action in the process of narrowing. When the travelers i are under the needle-bits d, the fingers tare in contact with the recesses t in the cams 6 as shownat the right-hand side of Fig. 3, and when the travo are levers supported at ornear their centers by means of studs 0', formed upon or connected with the exterior of the cam-cylinder 0 and provided at their outer ends with lugs or shanks 0 working in oblong slots 0 in the cam-cylinder O. The extremities of these shanks c extend through to the interior of the cam-cylinder O and support the travelers 1. The ends of these travelers i are beveled upward and inward, as shown, in order to permit them to be depressed by the needle-bits when the cam-cylinder is rotated back and forth during the operation of fashioning.

c are levers connected at or near their centers with studs 0? upon the exterior of the cam-cylinder O, and having at their ends shanks 0, extending through oblong slots 0 into the interior of the cam-cylinder 0. These shanks c are connected with and carry the fingers i. a

v s are small springs connected with the out side of the cam-cylinder O and with the levers c and adapted to shift the travelers 2' upward into contact with the ring b or with the bits cl of the needles D that have previously been thrown into contact therewith.

s are springsconnected with the outsideof the cam-cylinderO and with. the levers c near the shanks 0 thereof, in order to maintain the fingers 7: normally in contact with the cavities i c are links connected with the levers c by pivotal connections c and withthe levers c by slot-connections 0 The object of the slot-connection 0 is to permit the fingersi to slide over the needle-bits d in one direction without shifting the levers c and travelers i and also to insure the operation of the fingers 11 by the travelers 1' j are keys pivotally connected with the outside of the cam-cylinder O and provided with pins for engaging the levers c and c Thesekeysj serve to shift and lock the levers in such position that the travelers i" and fingers t' are entirelyout of range of the needlebits, or they permit them to assume such a position that the travelers 73 cause the fingers to engage the needle-bits.

The operation of throwing needles into action during the process of Widening is accomplished by means of the following mechanism.

f are travelers located on opposite sides of the came and farther from it than the fingers t. The travelers f are adapted to work in recesses e in the cam 6 and arelozenge-shaped, as shown, so that when they are shifted in one direction they ride over the bits d of the needles in operative position, and when they are shifted in a reverse direction they ride under the same and hence occupy positions in the recesses e.

1" are hammers normally occupying positions above all the bits (Z of the needles, and in the space between the ring b and its flange 12 Moreover, each of these hammers f is adapted to strike one needle-bit at a time and knock it into range of the auxiliary cams e and e. The movements of these hammers f are controlled by means of the travelers f through the instrumentality of a system of spring-actuated levers comprising the following mechanism:

f are levers pivoted at or near their ends upon studs 71 projecting from the exterior of the cam-cylinder C, and provided at their other ends with shanks f extending into the interior of the cam-cylinder O, and working in oblong slots n'in the side walls thereof. The hammers f are connected with and carried by these shanks f s are springs connected with the exterior of the canrcylinder C, and with hooks f 4 extending in rear of the points of pivotal support n of the levers f These springs s serve to maintain the hammers normally in contact with the flange b f are levers pivoted at or near their centers by means of lugs 02 upon the exterior of the canrcylinder O, and having their inner ends provided with shanks f, extending into the interior of the cam-cylinder through oblong slots a The travelers f are connected with and carried by these shanks f".

s are springs connected with the exterior of the cam-cylinder O, and with the other ends of the levers f in order to shift the travelers f normally above the needle-bits d by forcing them out of the cavities e f are links connected with the outer ends of the levers f by pivotal connections f and with the central portions'of the levers f by means of slot connections f so that when a traveler f rides above the needle-bits (Z that are in contact with the cam e a hammer f is caused to strike a blow upon a needle-bit d, and when the travelers f are beneath the needle-. bits (Z that are in contact with the cam e or in other words are in the cavities e the hammers f remain at rest underneath the flange b of the ring 12 The object of the slot connections f is to afford the travelers f a slight range of play without affecting the position of the hammersf.

f" are keys interposed between the levers f and f and pivotally connected with the exterior of the cam-cylinder C. These keys f are provided with pins that serve to force the levers f and f apart, whereby the travelers f and hammers f are shifted below and above the needle-bits, and consequently into an inoperative position. a

The mode of operation of the hercina-bovedescribed knitting-machine is as follows: The

needle-cylinder B is adjusted to the proper height with reference to the needles by means of the movable ring (a and crown-cams a in the usual manner, and is then clamped to place more readily and more securely than has been heretofore possible by means of the clamping device comprising the slot 1), handlever a and jaw a, whereupon the cam-cylinder is rotated in the usual manner by means of a gearing, (not shown,) and the needles D are consequently operated by the cams E in such manner that, in connection with the thread-guide G, they produce a tubular web. In order to accomplish the operation of narrowing the web during its formation, the thirty-six needles shown above theline 1 1 in Fig. 2 are thrown out of range of the operatingcams E into contact with the ring D by means of the handle a and stems or rods of, connected with the carrier (L5. The narrowing operation is performed by knitting back and forth upon the needles below the line 1 1 in Fig. 2 and throwing out a needle first on one side of the machine, beginning with the needles nearest the line 1 1, and then on the other side of the machine, and so continuing until the two sets of needles between the lines 1 l and 2 2 and 1 1 and 3 3 are thrown out of action. This operation of throwing needles singly and successively out of action is accomplished automatically by means of the fingers 17 and travelers t' and their accessories I after the keys j have been shifted into proper position for releasing the levers c and c in the following manner. \Vhen the cam-cylinder O is shifted toward the right in Fig. 3, the traveler 2' (shown at the right-hand side in said figure) slides along beneath the bits cl of the needles that have been previously thrown out of action, and thus causes the point i of the corresponding finger i to oecupy a position in the cavity i because the traveler L" and its corresponding finger t' are constrained by the levers c and 0, links 0 and springs s and s to move in the same directionthat is, both upward or both downward. During the progress of the cam-cylinder 0 the traveler '7 runs off the bits (Z of the needles previously thrown out of action at the same time that the point '5 of the finger i runs under the bit of the next needle to be thrown out of action, and as soon as the traveler runs off the last needle-bit cl, in contact with the ring b the finger 2' engages the needle-bit and shifts it into range of the cam e whereby it is transferred into contact with the ring D and hence out of operative position. During the remainder of the travel of the cam-cylinder toward the right the traveler 2 runs in contact with the ring 0 and thus maintains the finger t'above the bits (I of the needles that are in contact with the cam e Vhen the cam-cylinder C is shifted toward the left, the pointvl of the finger t' rides freely over the bits (I of theneedles that are in contact with the cam 0 The abovedescribed operation is repeated whenever the ICC ITO

cam-cylinder O is'rota-ted toward the right and until the required number of needles-in the present instance, twelve needlesat the right hand side of the' machine have been thrown singly and successively out of action. Of course the traveler i" and its corresponding finger t at the left-hand side of the machine operate in a similar manner whenever the cam-cylinder Ois shifted toward vthe left, and cause the needles to be successively and singly thrown out of action at the left-hand side of the machine. The result of the reciprocation of the cam-cylinder is to cause needles to be thrown out of and into action singlyffirst on one side of the machine and then on the other side thereof. The web is widened by first throwing the fingers 2' and travelers 7 out of operative position, and then throwing the travelers f and hammers f into operative position in the manner hereinabove described, and then continuing the operation of knitting back and forth. When the cam-cylinder is shifted toward the right in Fig. 3, the traveler fat the left-hand side in Fig. 3 rides over the needle-bits d, that are in contact with the cam 6 and thus causes the corresponding hammer f to strike the last needlebit that was previously thrown into contact with the ring 6 on the left side of the machine. The blow of the hammer f forces the.

needle-bit into range of the cam e whereby it is transferred into range of the operatingcams E of the machine. During the remain der of the travel of the cam-cylinder toward the right, the traveler f rides upon the needle-bits d, that are in contact with the cam 6 and thus permits the hammer to-remain ininoperative position. hen the cam-cylinder is shifted toward the left, the said traveler f by reason of its shape is forced under the bits of the needles that are in contact with the cam e whereby the corresponding hammer f is permitted to remain at rest. Of course the traveler f at the right-hand side of Fig. 3 and its corresponding hammer f are operated in a similar manner when the camcylinder 0 is shifted toward the left. The result of the reciprocation of the cam-cylinder C is to cause the hammers f to throw needles singly and successively into action, first on one side of the machine and then on the other side thereof. After all the needles have been thrown into operative position by the hammers f, the levers f and f are thrown into inoperative position, the carrier a is shifted downward, and the needles above the line 1 1 in Fig. 2 are pushed by the hand into action, whereupon the formation of the tubular web is continued in the usual manner.

Among the many advantages possessed by the hereinabove-described machine the following may be particularly mentioned: first, the bits or hubs -of the needles are all of the same length, so that the needles may be employed interchangeably, and, second, the operations of throwing needles singly into and out of action are performed in a positive manner, so that the production of perfect goods in a rapid manner is assured.
