SPECIFICATION forming part of Letters Patent No. 691,888, datedfl'anuary 28, 1902. Applioetion'filed March 15, 1897; Serial No. 627,468. (No model.)

To all whom it may concern: Be it known that I, CHARLES J. APPLETON, of Long Island City, in the county of Queens and State of New York, have invented a cer- 5 tain new and useful Improvement in Knitting-Machines, of which the following is a specification.-

Myimprovement relates mainly to circularknitting machines. V I0 I will describe a machine embodying my improvement and then point out the novel features in claims.

"In the accompanying drawings, Figure l is a top view of a machine embodying my im- Fig. 2 is a front elevation of the same. Fig. 3 is a transverse vertical section taken at the plane of the dotted line 3 3, Fig.

2, looking in the direction indicated by the arrows at the end of said line. Fig. 4 is a transverse vertical section taken at the plane indicated by the dotted line 4 4, Fig. 2, but omitting certain parts which might be repre sented in the background of said figure. Fig.

, 5 is an enlarged transverse vertical section taken at the plane of the dotted line 5 5, Fig. 2, and looking in the direction of the arrows marked at the end of said line. Fig. 5 is a top view of the top bar shown in Fig. 5. Fig.

b is a central longitudinal section parallel 0 with the front of the machine. Fig.-7 is a transverse vertical section taken at the plane of the-dotted line 7 7, Fig. 6. Fig. 8 is a transverse vertical section taken at the plane of the dotted line 8 8,-Fig. 6. Fig. 9 isa cen- 5 tral vertical section of the cylinder in which the knitting is done and correlated parts, this view being upon a large scale. Fig. 10 is a side elevation of parts shown in Fig. 9 looking in the direction indicated bythe arrow 0 10 marked adjacent to Fig. 9. Fig. 11 is a horizontal section taken at the plane of the dotted line 11, Fig. 9, the needles being ornitted. Fig. 12 is an elevation of cam mechanism comprised in Fig. 9, but instead of being shown of cylindrical form it is developed. Fig. 13 is a vertical section at the plane of the dotted line 13, Fig. '12. Fig. 14 is a vertical section at the plane of the dotted line 14, Fig. 12. Fig. 15 is a plan of certain parts shown in Fig. 9, including cam-rings. Fig. 16 is a vertical section of certain parts,including a 'pattern chain that serves to vary the length of stitches. Fig. 17 is an elevation, partly in section, of mechanism for regulating the tension and for throwing in an extra thread 5 for thickening any part of a knitted fabric.

Similar letters of reference designate corresponding parts in all figures.

It may be added as a summary of the various views that Figs. 1, 2, 6, 10, and 17, so 6 far as the full lines are concerned, represent the parts in the positions they occupy while the cam-cylinder is oscillating, and Fig. 17 in dotted outline and Figs. 9 and 11 represent the parts in the positions they occupy 6 during the time that the cam-cylinder is 1'0- tating. The remainder of the figures are not distinctive as to the positions of the parts for either operation.

A designates a cylinder, through which the 7t knitting fabric descends. It may be made of any suitable material and will preferably be open at both ends. As here shown, it is provided in the lower portion with an internal recess a, the top of which forms a shoul- 7 der a, that rests upon the upper part of a cylinder A. This cylinder A is open at both ends and at the lower end is fastened to a table or bench B of any suitable form, an opening being provided through it for the passage of the knitted fabric. As here shown, this cylinder A is provided with an outwardly-extending base-flange a in the outer portion of which is a rabbet a for fitting the opening in the table or bench B.

The cylinder A may be secured in place by screws or otherwise passing through its basefiange and engaging withthe table or bench. To prevent the cylinder A from accidentally turning relatively to the cylinder A, the latter is provided in its upper edge with notches a. and the former with lugs a extending downwardly from the shoulder a of the cylinder A. These lugs may consist of screws inserted in the shoulder of the cylinder A.

In the outer circumference of the cylinder A are a number of vertical grooves a, in which are fitted needles 0' C The shanks of the needles 0 are longer than those of the needles 0 as may be seen in. Fig. 9. The Ice needles may be held in place by helical springs l, surrounding thecylinder A and passing through notches in the ribs or partitions between the needle-receiving grooves, so that they may press against the shanks of the needles. By contacting with the needle-shanks they produce sutlicient friction to retain the needles in any positions into which they may be adjustedf 130th series of needles may be of ordinary form, except that the needles 0' have extra lugs 0. Besides these lugs the needles C have lugs and the needles C have lugs 0 The lugs c are for coaetion with a jacquard mechanism,which will presently be described. The lugs c of the needles 0' and the lugs c of the needles C are for coaction with triangular cams D D arranged'outside of the cylinder A and supported by a cam-cylinder D. These cams are shown well in section in Fig. 9; but their shape may best be understood by reference to Fig. 12,whcre they are developed. These cams D D are arranged in relation to recesses formed in the inner surface of the cam-cylinder I), so that they may be withdrawn into the recesses in order to be inoperative or shifted beyond the recesses to become operative. As here shown, the cam I) is supported by two shanks or rods d and the cam D is supported by shanks or rods (Z having a sliding connection with a block (I, that is fastened to the exterior of the cam-cylinder. The shanks or rods (1' of the cam I) are connected to ayoke (1, having on that side which is the nearer to the cam-cylinder a cam-face d. A similar yoke rl" connects the shanks or rods (Z of the cam D and is provided with a camface (1. Springs d surrounding the shanks or rods d of the cam I), tend to force this cam out of its recess into an operative position, and similarsprings disurroundingtheshanks or rods (1 of the cam D perform the same ofiice for the cam l). notched to embrace the shanks or rods (1 of the cam D, is fitted to move vertically between the outer side of the block d and the cam-cylinder D and serves by presenting a suitably-shaped surface to the cam of the yoke d to move the latter away from the said block d, and consequently to withdraw the cam D into its recess. A similar slide at' coacts in the same way with the yoke (Z -to withdraw the cam D into its recess. The slides d d are actuated by levers (1 d, which are pivotally connected to the slides and have ring-shaped portions surrounding the cam-cylinder D. These levers are pivoted by pins or trunnions d d to the sides of the cam-cylinder at diametrically opposite portions. The purpose of pivoting these rings or levers d (l is to constitute rockers or rocking levers thereof. Obviously when both the cams D I) are shifted into operative positions and the cam-cylinder is rotated or oscillated the cams will cause both sets of needles 0 C to be reciprocated vertically. By withdrawing the cams D' D both series A slide (Z slotted or I of needles will cease to be operated by these cams. At times the needles 0 may be operated by cams D and the jacquard mechanism hereinafter mentioned. will merely mention these cams D in passing, and later on fully describe their construction and operation. Above the cam D is a cam D, which coaets with the cam D and also with the cams D It is a fixture on the inner side of the cam-cylinder D, and hence is not adjustable horizontally into different positions like the cams D D Above the cam D are cams D D". The cams D D are incapable of any horizontal movement into and out of operative position. To make the operation of these cams perfectly clear, I will add that the cam D is incapable of any movement except a horizontal movement relatively to the inner surface of the cam-cylinder for the purpose of adjusting it int-o an operative or an inoperative position. The cam D is susceptible only of a similar movement.

The cams D have no horizontal motion, butthey are fastened to vertical slide-bars D which work in grooves formed on the innersurface of the cam-cylinder D. Hence the cams D are susceptible of an up-and-down movement. The cam I) is "attached to one of these slide-bars 1). Hence it may move similarly to the cams D and with them. The cams D D have no movement of any kind except that they participate in the oscillation or rotary movement of the cam-cylinder, in which also all the other cams D D l) D"'partieipate.

The slide-bars D are shown as retained in the grooves (Z by reason of the fact that the cams D D extend across such grooves. Shanks or rods (1 extend rearwardly from the slide-bars D through vertical slots formed in the cam-cylinder D and bear upon springsupported rods (1", which are fitted to vertical sockets d, with which the exterior of the cam-cylinder is provided, springs (1 being arranged in these sockets below said supports (1". Thus the slide-bars D will be raised to their upper position. They are lowered by means of cams D fitted to the exterior of the cam-cylinder (see particularly Figs. 10, 11, 13, and 14) and capable of moving horizontally upon the circumference of the camcylinder. As here shown, these cams are longitudinally slotted and held in place by screws passing through slots and engaging with tapped holes in the exterior of the camcylinder, springs being interposed between the heads of the screws and the cams for keeping them in place with sufficient friction to preclude accidental movement. There are two of these cams; but they may be made integral and are so represented. The lower edge of each is provided with a notch (1 Then the cams D are moving in one direction, both the slide-bars I)" and the cams D D connected to them, will be lowered, and upon a movement of the cams D in the reverse direction the springs (1 will raise the slide-bars saidcams D D., The means for imparting movement to the cams D will be describedlater on. It is sufficienthere to say that it is;.directly efiected by a; rod D pivotally connected at one endwith the cams and at the other end with parts from which it derives motion.

It will be manifest from whatI have already stated that when the cams D D are adjusted into operative position, as shown in Fig. 9, and the cam-cylinder is rotated both series of needles 0 (3 will be reciprocated vertically by means of these cams in conjunction with the cams- D D D D.

The manner in which the lugs c of the needles C are operated upon at this time isindi c'ated by-dotted line 61- in Fig. 12, and the manner in which the lugs c of the needles C are operated upon at the same time is indicated by the'dotted line (1 in the same figure. I have shown arrow-heads at the ends of these lines (Z d for the purpose of indicating the relative direction cf the needles and cam-cylinder. The actual direction of movement of the cam-cylinder is indicated by the arrow 01 in Fig. 12. To avoid any misapprehension, I may add that although the cams D D are in their operative positions at the same time, yet neither occupies an operative position during the whole time that the other occupies such a position, one being adjnsted into its operative position and out of its operative position in advance of the same actions in the other. While the machine is operating in this way, straight work is being done, or, in other words, work like the leg of a stocking as distinguished from the heel and toe. I do not, however, mean that the work is necessarily straight in the sense that it does not vary circumferentially in size. If during any portion of this straight work it were desirable to elongate the stitches for the purpose of makinga looser texture to enlarge the fabric, the cams D and the cam D will be suitably lowered to give an extra length of reciprocation of the needles at certain times, the operation of these cams D D being determined, as already indicated, by a pattern-chain H, hereinafter to be described.

For making work which is not straight as, for example, theheels and toes of stockings the cam-cylinder will be oscillated instead of rotated and the cams D D will be adjusted into inoperative positions within their recesses and the needles 0 will be left inop' erative. The needles 0 will remain operative, but will then be actuated by the jacquard mechanism presently to be described, the upward movement being given by the jacquard mechanism and the downward movement by the cams D D. The action of the needles Cduring this time is indicated in Fig. 12 by the dotted line (2 in one direction and by the dotted line (Z in the other. During this work the stitches may be lengthened by a downward movement of the cams D produced by the'pattern-chain H, already mentioned and hereinafter to be described. The line (1 indicates that the needles 0 will notbe affected during this action, because their lugs 0 may pass the cams without contacting with them.

I will now describe the means for rotating or oscillating the cam-cylinder. At the base of the cam-ring is an outwardly-extending flange,forming a bevel gear-wheel d 'fiand this derives motion from a bevel gear-wheel d, which is affixed to a shaft E. This shaft is journaled in brackets e e extending downwardly from the table or bench B. Preferably antifriction-rollers c1 will be interposed between the base-flange of the cam-cylinder and the base-flange of the cylinder A. Any

suitable means may be provided for retaining the base-flange of the cam-oylinder in proper relation to the base-flange of the cylinder A-as, for instance, an annular plate bar E, which is fitted to slide in a groove formed in the top of the table or bench B in a direction parallel with the front. With one end of this bar E a spring e is combined, it being here shown as arranged in a socket a", connected with the bracket e, which contributes to the support of the shaft E. Motion of the bar E in one direction is efieoted by this spring 6 The reverse motion is imparted to the bar by means of force transmitted through a post F in a manner which may best be described later on. When the belt-shifter E is moved in such direction as to apply the belt to the pulley E, which is affixed to the shaft E, rotary motion will be imparted to the shaft E continuously, and a rotary movement of the cam-cylinder D will consequently be produced. When the beltshifter E is moved in the reverse direction, the rotary movement of the cam cylinder D will be terminated, and motion will then be transmitted through the belt-pulley E and pinion E to a gear-wheel E aflixed to a rotary shaft E ,supported by a bracket 6 which is affixed to one of the side pieces of the table or bench B. Affixed to the same shaft E is a gear-wheel E which so far as the mechanism now under consideration is concerned may be considered merely as a crank, it being provided with a crank-pin e, which transmits motion through a rod e to a gearsegrnent E, oscillated upon a shaft or stud e, which is supported by a cross piece or stretcher e", connected to the two side pieces of the table or bench B. An adjustable connection is afforded between the rod e and the segment E by means of a slot e in the segment and a bolt e passing through said slot and through said rod. Thus provision is af- IIO forded for varying the throw of the segment. The tooth-segment E engages with a small gear wheel or pinion E mounted loosely upon the shaft E. This gear-wheel E forms .partof a clutch, and therefor has on one face a cylindrical boss 6 with a single radial notch e Just beyond this cylindrical boss the shaft E is provided withaspline e, which is here shown as formed upon an enlarged portion e of the shaft. Upon this enlarged portion of the shaft is fitted a clutch-piece E, having a clutch-tooth e capable of engaging with the notch e of the gear-wheel E This tooth is shown as spring-actuated, and for this purposeis provided with a shank e", which passes into a socket in the clutchpiece E and iscombined with a spring 6 for moving it outward into the notch e of the gear wheel E Obviously when the clutch-piece E is moved into such position that its spring-tooth 6 will engage with the notch e of the gear-wheelli. the latter will be engaged with the shaft E, so as to be capable of turning said. shaft. As the motion imparted to the gear-wheel E by the segment E will be oscillatory, a corresponding movement will be imparted to the cam-cylinder D whenever the belt-shifter E shift-s its belt upon the pulley E The clutch-piece E is shifted into and out of engagement with the gear-wheel E by means of a rod e, at-

, tached to the slide-bar E said rod 6 being bifurcated atits lower end and provided there with pins for engaging a circumferential groove with which the clutch-piece E is provided.

Now I will explain the means for operating the lovers (1 (1, through which the cams D D are adjusted into and out of operative positions. Upon the post F a tappet-blockf is mounted, so as to be free to move vertically, but so as to be incapable of any rotary movement. As here shown, this tappet-block is provided with a socket vertically arranged to fit loosely upon the post F, and a crosspiece f extends through the post into vertical slots f with which the sides of the tappetblock are provided. One side of the tappetblock fis provided with notches f f. Upon this side of the tappet-block,above and below the notches, tanpets F F F 3 are arranged. The levers d d fiwhich effect the shifting of the cams D D into and out of operative position, are provided with extensions or fingers d 01 that extend into the notches of the tappet-block f. By cooperating with the tappets F F F these extensions or fingers d d are in the machine as here organized. The tap pets F F F operate to shift the levers (1 d by means of a vertical movement which they have in common with the tappet; block f. This movement is produced by a vertical movement of a rod F which is moved by a pattern-chain G, it being provided at its lower extremity with a blockf for bearing upon the pattern-chain. The pattern-chain merely elevates the rod F". It is lowered by gravity aided by a springf. Itwill be understood that whenever the pattern-chain raises the rod F it 'will raise the tappet-blockf and cause the tappets F F F to shift the levers d (Z controlling the position of the cams 1) D I will now describe the manner in which I operate the slide-bar E The upper end of the rod F is provided with a socketin which is fitted a pin f and below this pin a supporting-springf Whenever the rod F is raised, the pinf will first contact with the tappet-blockf; but this will have no effect upon the tappet-block, because the springf is so light that it will permit the pin f to descend into the socket of the rod F \Vhen the rod F elevates the tappet-block f, a plate f which is attached to the bottom of the tappet-block f, will be raised into the plane of an antifriction-rollerf carried by the cam-cylinder D,it being shown here as mounted upon an arc-shaped piece 1, which is attached to the base-flange J" of the eam-cylinder by means of postsf The rotary or oscillatory movement ofthe cam-cylinder will cause this antifriction-rollerf to coact with the opposite edge of the plate f, and thus force the tappct-blockf in a direction away from the cam-cylinder. As the tappet-block is mounted upon the post F and the latter is rigidly connected with the slide-bar E the latter will participate in the movement of the tappet-block in a direction away from the cam-cylinder. It will be seen, therefore, that the cam-cylinder by means of its ant-ifrictionrollerf operates the belt-shifterE and also connects and disconnects the clutch E E". The movement of the tappet-block produced by the antifriction-rollerf will not, however, move the tappets F F E" into such position as to prevent them from operating upon the levers d d. Attached to the under side of the plate f is a plate f. When the tappet-block is by the rotation of the cam cylin der D moved by the antifriction-rollerf in a direction away from the cam-cylinder, the pin will rise in front of the platef, and thus the tappet-block will be prevented from returning to its position adjacent to the camcylinder until the pattern-chain G permits the rod F to descend. In order to relieve the pin f of any friction, the motion of the tappet-block f, produced by the antifrictionrollerf", will be great enough to move the plate f slightly away from the side of said pin.

The pattern-chain G has a number of links IOC no l

- screws g or otherwise.

g of slight depth or thickness and a number of links 9' of greater depth or thickness. Gonsidered with reference to their elfect these are high and low links. The low links permit the rod F to descend under the influence of gravity, with or without the aid of the springf and the high links elevate'the rod to produce the efiects already described. Only when the high links pass under the rod F does this pattern-chain have any function. This pattern-chain is moved by means 'of a sprocket-wheel G, which is loosely mounted upon a sleeve 9 that is shown 'as formed integral with the bracket e, that contributes to the support of the shaft E. At the side of the sprocket-wheel G are two ratchet-wheels I The ratchet-wheel G is fastened to the side of the sprocket-wheel by means of The inner circumference of this ratchet-wheel G2 is rabbeted .andwithin it fits a revcrsely-rabbeted cylinder g which forms the hub of the ratchet wheel G As shown, it is made in a separate piece and fastened to the ratchet-wheel proper by means of screws. The cylinder or hub g is pressed by pins g upon that side which is adjacent to the sprocket-wheel G, and these pins extend into recesses with which the sprocket-wheel is provided, springs being interposed between the bottoms of the recesses and the pins, so as to force the ratchet-Wheel G3 away from the sprocketwheel, and consequently away from the ratchet-wheel G The purpose of the springs is to produce enough friction between the overlapping portions of the ratchet-wheel G2 and the hub of the ratchet-wheel G to prevent any accidental movement of thelatter.

G designates a slide which is provided with vertical slots g through which pass bolts 9 A spring g fastened at the lower end to a stud g extending from the slide G and at the other end to a pin g extending from the bracket 6 tends to raise said slide, and a cam g, affixed to the shaft E and operating upon an antifrict-ion-rollerg", mounted upon the slide G serves to lower said slide. A pawl 9 pivoted to the slide, is held into engagement with both ratchetwheels by means of a spring 9 For each rotation of the shaft E the pawl coacts with the ratchet-wheels. The ratchetwheelG has'five teeth of the same projection, and every sixth tooth g is a deeper tooth. \Vhenever the pawl coacts with one of these deeper teeth 9 it is alsopermitted to coact with an adjacent tooth of the ratchet-wheel G but at other times it does not coact with this ratchet-wheel at all. Because of this combination of ratchet-wheels with the sprocketwheel that operates the pattern-chain G it requires six rotations of the shaft E to produce one movement of the sprocket-wheel equal to the length of one link of the pattern-chain G.

I will now describe the means for operating the cams D*, by which the up-and-down movement of the cams D D is effected. I

have already stated that these cams D are operated by a rod D which at one end is pivotally connected to them. At the other end this rod is pivotally connected to a pin d that projects'npward' from a lever (1 that is fulcrumed by means of'a stud d in a bracket (1 attached to'the exterior of the cam-cyl: inder I). Another leverd is provided with a longitudinal slot, through which also passes the pin (1 that connects the lever d with the rod D. This lever 11 is fulcrumed bya. pin or screw d to a bracket (1, that is fastened to the exterior of the cam-cylinderD. D is a rod having a sliding movement in a hollow pos' d", which is here shown as connected with the table or bench B by means of a a screw-threaded boss. This rod is raised and lowered by means of a pattern-chain H,which willbe presently described. At its upper end it has two different projections at d. The projection d is inclined .on the side which is adjacent to the lever d It may be inclined all the way around, as represented. The upward projection, while shown here as a cylinder, need not 'be anything more than a finger. It is not inclined on its operative surface. The rod D is capable of adjustment to such a position that neither of its projections d d" will have any effect upon the levers d (1 It may also be moved intoa position, as'shown in Fig. 16,- where its projection '61 will operate upon the lever (1 and its projection d I will have no effect upon the lever d If elevated still more, its projection (P will be moved beyond the plane of the lever 01 and its inclined projection cl will be brought opposite the lever d, as indicated by dotted lines in Fig. 16, and according to whether different portions of the inclined surface of its projection (i will be opposite the lever (1 so will the effect of the said projection upon this lever be varied. I The rod D is connected at its lower end with'one end of a lever d*'',which at the other end is fulcrumed to a bracket d. Intermediate of its ends it is provided with an antifriction-roller (Z and this coacts withthepattern-chain ll. Thepattern-chain 11 passes around the sprocket-wheel G and derives motion therefrom in harmony with the pattern-chain G. This pattern-chain H comprises different links, some low links 71',

which allow therod D to descend to such a position that neither of its projections (Z (Z will be operative, some links 7L2, which are graduated in height, so as to elevate the rod D sufficiently to bring different portions of its inclined projection (1 into operation for varying the transverse dimensions of the fabric-as, for instance, while knitting the calf portion of a stockingsome high links h for elevating the rod D into such a position thatthe lower part of its inclined projection d will continuously be opposite the end of the lever d'' for the purpose of knitting several lines of extra long stitches for indicating the division line between two stockings, and occasional depressed links h occurring one at a,

said projection, and thereupon the cams D will be shifted into operative position; but the operative position will vary in degree according to the elevation of the projection 01 of the rod D.-, -When the rod D is lowered sufficiently fqrits projection (Z to occupy the same planeas theend of the lever (1 the rotation of the cam-cylinder will cause said "projection d to oscillate the lever d in such a direction as to shift the cams D into an inoperative position.

I will now describe the jacquard mechanism, premising that it is more particularly represented in Figs. 2, 4, 5, and 5'. E designates a wheel which has heretofore been considered merely in its function of a crank for imparting motion to the gear-segment E for oscillating the cam-cylinder D. It will be seen that this wheel is a gear-wheel and that it engages with a similar gear wheel or pinion I, that is afiixed to a shaft 1, journaled in brackets 1', extending from the side pieces of the table or bench B. Affixed to this shaft If is an eccentric 1 whose rod 71' extends to toggle-levers 2' i The toggle-lever 2' is mounted loosely upon a cross-rod or stretcher e connecting the side pieces of the table or bench B, and the toggle-lever 2' is pivotally connected by means of a pin or screw 71 to a block i which is made in the form of a collar and adjustably connected by means of a set-screw 2 to a sleeve 2' The sleeve i is mounted upon an upright rod 2' which at the lower end is supported in a bracket 2' and at the upper end is supported by means of an arbor 1' which is here shown as made in the form of a screw fastened to the table or bench B. The eccentric-rod is pivotally connected by means of a pin 2' to the toggle-lever '6 The sleeve i is provided with a horizontallyextending bar 2' having upon its ends downwardly-extending lugs i 1'. To the lug c is pivotally connected one end of a rod 11 which at the other end is pivotally connected to a yoke 1', that is loosely mounted upon the shaft or stud e". A similar rod 11" is pivota-lly connected at one end with said yoke and at the other end with the lug i its connection with this lug being made by extending a pin through a lug 1' and thence into the lug 2' The lug 1' is elongated horizontally, so as to provide room for the passage of screws 2'", that are employed for securing this lug rigidly to the lug 2. When the eccentric operates the toggle-levers i i in one direction, the sleeve i will be raised, and when the toggle-levers are moved in the reverse direction said sleeve will be lowered. Upon the raising of the sleeve i the lug -i will be carried upwardly by means of the crossbar 1"". The purpose of the rods 2' 2' and yoke 01 is to secure a parallel mot-ion for the said rod t". Rigidly connected with the lug 2' is a frame comprising a bar 2' and two bars 2' extending from the ends of the latter at right angles to it. The outer ends of these bars 2' are connected by an independent bar '5 The bars 2' 11 support'studs 2' 11 upon which gear-wheels 2' are loosely mounted. Thesegear-wheelsintermesh. Affixed to the gear-wheel 2' is a ratchet-wheel 2' with which engages a pawl 1' which is pivotally connected to a stationary post 1' which is mounted upon the cross-piece or stretcher e of the table or bench B. A spring 71 holdsthe pawl e inengagement with the ratchet-wheel 2' When the gearwheels and ratchet-whee1 are elevated by the eccentric 1 no rotary motion of the gearwheels will occur, but the pawl will play over two teeth of the ratchet-wheel and take a new position beyond the second tooth. The gearwheels and ratchet-wheel will be carried up beyond the reach of the pawl, and the latter will then be drawn against a pin 2' and remain there until the descent of the gearwheels and ratchet-wheel. Upon the descent of the gear-Wheels and ratchet-wheel the pawl will impart a short rotary movement to the ratchet-wheel, and consequently to the two gear-wheels. This motion in the present instance will be a quarter-rotation.

Affixed to the gear-wheels t are sprocketdrums 1' with which are engaged chains I 1 comprising jacquard-cards r whose vconstruction is best shown in Fig. 2. The drums are square, and each surface corre- ICO sponds in size with a jacquard-card. The

drums of course are rotated a quarter-turn each time that the ratchet-wheel 1' and the gear-wheels 2' 71 are similarly rotated. As they are rectangular, they will always stop with a flat surface presented upwardly. To make sure that they shall always stop with the upper surface exactly in a horizontal position and to prevent them from accidentally turning, I combine with them a bar i which extends across them near one side and coacts with rollers 2' with which the corners of the drums are provided. This bar has connected to its ends rods that extend downwardly through brackets on the bars 1' and below these brackets are fitted with springs 71 which rest at the lower ends upon cross-pins passing through said rods. Thus it will be seen that the bar i will be held downwardly by springpressure upon the rollers 2' of the drums and also upon the ca'rds which happen to be at the top of the drum, and yet this bar may rise to permit of the rotation of the drums. Reference to Fig. 5 will show that the top of the bar 2' has a horizontal extension Wlrom one side. This extension is to cover the space between the two drums, and hence between the two uppermost jacquard-cards.

It will be seen that the uppermostjacquardcards are beneath the needles 0'. The cards are provided with holes 2, and only those needles whose lower ends can pass through such holes will be left unmoved when the cards move upward. ent in the different cards. "The holes 1:0f alternate cards are narrowed at one end, so that they will only permit the lower extrem I ity of the opposite needle to pass through without permitting the lug c to pass through; Thus the needles which are at the narrowed ends of these holes will be moved upward a less distance thanthe others. The needles thus operated will be working along'one edge of the knitted fabric--as, for instance, along an edge which will subsequently form part of that seam or point of union which occurs at an angle in the heel portion of a stocking where the work turns at approximately a right angle. Each needle which is lifted, as just described, less'far than the remainder will be the last-operated needle in its course of knitting or stitch-forming, and by reason of the fact that it is lifted less high than the others it will at the next succeeding operation have a second loop formed around it in contiguity with the last previous one instead of being made as an independent loop for a stitch. Thus a double loop will he formed, because the next to the last loop will not be released, by reason of the shorter upward movement of the needle. In the diagram of Fig. 12 the lines c1 and 01 show the paths at the commencement of each reciprocation which the needles lifted less far than the other needles will take, and the paths (Z and 01 will meet as the stationary cam D contacts with the two kinds of needles.

I will now describe the holddowns. They consist of a number of independent radiallyarranged bars J, having hooks j, which extend rom points intermediate of the length of the bars upwardly and toward the axis of the cam-cylinder, and lugsj', extending downwardly from near their outer ends. The inner ends of these bars extend into a rin-gj which is fitted into a rabbet formed in the upper part of the cylinder A and engaged with it, so as to be stationary. In the exterior of the upper portion of the ringj is a circumferential groovej into which the inner ends of the holddown-bars J extend. In

the upper end of the cylinder A are a num-,

j*, with which the exterior of said ringj is provided. In the upper part of the cam-cylinder is an annular rccessj, into which the The holes i -are differ-' l gs of the holddown-bars extend. Cams ,7 ,7." 7 9are arranged within the recessf', near the outer circumference thereof, and cams 7 7 are arranged in said recess near'the inner circumference thereof. These two sets of cams cooperate with the lugsj of the hold down-bars to shift said holddown-bars radierate upon the fabric with a pushing move-" ment. 1 l

I will now describe the thread-guide. As

here shown, it consists, essentially, of an eye K, rigidly afiixed to a bark, that is hinged at '70 to a block k the latter being fitted to slide vertically upon a post 15 fastened to the block 0?, that is attached to the exterior of the cam-cylinder D. The sliding block k is connected, by means of pivot-pins k, with the lever (1 When the lever 01 is raised or loweredat that end or arm which is connected with'the sliding block 10 the latter will be similarly moved, and such movementwill be imparted to the thread-guide. During the operation of the thread-guide it does not have any oscillating movement upon the pivot-pin 7t, because just forward of said pivot-pin it is supported upon a shoulder portion of the sliding block 70 The object of the pivot-pin k is to permit the thread-guide to be drawn backward out of the way. A ring 70 is rigidly connected to the bar It and encircles all of the needles when the latter are elevated, its purpose being to preclude the latches of the needles from being accidentally moved out of their proper position. When the bar 70 is swung back upon the pivot-pin 10, not only the thread-guide K, but also the ring it, will be moved out of the way. The thread-guide is reciprocated vertically at the time that the cam D is shifted into and out of its operative position, and hence when a change of Work occurs. The advantage of this will be seen-as, for example, when the change is from straight knittingto work requiring the jacquard mechanism. The cams D and D Fig. 12, being then in operation, thethrow of the needles is thereby lessened and the point at which the needle takes the yarn is less elevated, as will be clear from said figure. It is at this time the thread- ICO IIO

guide is lowered. Thus my thread-guide is seen that the guide 25 is pivotally connected eye 1", arranged upon a rocking plate I, which with the bar I by means ofa pin 1". While is fulcruined by a pin or screw 6, having an the cam-cylinder is oscillating the rod t is oscillating connection with the bar Each elevated to the position in which it is repre- 70 plate Z normally bears against a hub extendsented by full lines in Fig. 1?, and the extra 5 ing beyond the sides of the corresponding thread T is allowed to pass freely through wheel 1 thus acting as a brake.

The free end of the the eye I, each thread passes up through an thread will by the raising of the. guide i be eye Z in a rod i which is fastened to a sleeve adjusted into a position where it may engage 75 Z, that is mounted upon a stud 1", attached with the main threads, so as to be carriedinto to a side of the bar Z, a spring I being coiled the thread-guide. I may here remark that around such sleeve and connected at one end both the main threads T are brought together therewith and at the other end to a stationby passing through an eye Z formed at the my part. The tendency of the spring is to outer end of the bar 1;. \Vhen the lever i is 80 raise the rod Z, and hence this rod operates lowered, its rods t depress the plates l thus 1 5 .with a spring tension upon the. thread pass leaving the rollers Z free to rotate.

The rods Z are sprung downward as the from the latter through aguide t and thence thread is drawn through the guide K; but to the thread-guide K. The bar t is fastened whenever the eye Z on rod Z is drawn down rigidly to the post Z The lever 15 is fulto contact with plate Z it tends to lower said we crumed by a pin 25 to the bar t. Between the plate, relieving, partly, the pressure upon the rear end of the lever 25 and the bar 25" is a hub of wheel Z and thus acontrol is afiorded spring F, that is compressed every'time the of the tension upon the main threads. The forward end of the lever t is raised.
