Serial No. 155,661.

This invention relates to improvements in knitting machines.

The primary object of this invention is the provision of a circular knitting machine,

embodying improved means to knit thereon a fabric with terry threads held therein in the wales of the base yarn, in such manner that the terry threads provide loops outstanding at both sides of the fabric, in a slack 10 free relation, in a preferably thickly matted relation, so that the base yarn wales are sub stantially hidden, and produce a fabric simulating, in appearance only the well known Turkish towel, which is a conventionally woven product, in contra distinction to knitting.

A further object of this invention is the provision of means and an improved method for producing slack looped pile towelling;

0 wash rags; bath mats; bath robes; and other fabrics, by means of knitting.

A further object of this invention is the provision of an improved method or process for the knitting of fabric, by manipulating main knitting yarn in such relation as to provide a base fabric, and in cooperation with which is employed terry yarns drawn through and interknitted with the wales of the base fabric to provide slack outstanding loops in a closely matted relation at both sides of the fabric.

A further object of this invention is the provision of a method and apparatus for knitting looped terry fabric, such as described in my co-pending application Serial Number 146,680, filed November 6, 1926, and including departure from such application in the efficient manipulation of a plurality of terry threads to knitthe same in a novel relation in a base knitted fabric. a

A further object of this invention is the provision of knitting apparatus including three cooperating sets of needles, one of which is adapted to knit a base fabric, an-

other which is adapted to control a terry yarn for the formation ofslack loops at one side of the base fabric, and the other set of needles being adapted to control another terry yarn for the formation of slack loops at the opposite side of the base fabric.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevation, partly in section, of the upper part of the improved knitting machine, showing the needles of the same in position for the feeding of different yarns into the cylinder and dial needles.

Figure 2 is a vertical sectional View taken through the improved knitting machine, substantially on the line 22 of Figure 5 of the drawings.

Figure 3 is a plan view of the dial cap of the improved machine, showing the carriers thereon for the guiding of the main and terry yarns, as well as showing beard pressers, and guides thereon for holding latch needles open.

Figure 4 is-a developed plane View of both the dial and cylinder needles, showing three cooperative sets of needles, one set of which is shown in the upper row of needles; the same being dial needles; and the other two sets of which are shown in the lower row of needles, as being cylinder needles, and showing the same in their cooperative cam operated relation for the handling of knitting and terry yarns.

Figure 5 is a plan view, showing the cam operation upon the dial needles, with the dial cap and cam removed to expose the relative location and relation of the dial needles, in so far as the dial cam operates upon the same with respect to the needles of the cylinder, and the feed of the threads.

Figure 6 is a fra mentary sectional view taken through aportion of the cylinder, showing the grooved arrangement thereof for the reception in each groove of the cylinder of two needles, one of the needles being a latch needle to cooperate in the knitting of the base fabric, and the other needle being a beard needle for cooperatively controlling the terry thread to be looped at one side of the fabric.

Figures 7 to 11 inclusive are enlarged fragmentary views, somewhat diagrammatic and exaggerated, but showing progressively various steps in the knitting of terry looped fabric.

Figure 12 is a distorted diagrammatic representation of an enlarged fabric knitted upon the improved knitting machine, and after the improved method herein described, this view being merely intended to show the relative inter-knitting of the main and terry threads, and not being a simulation of the resultant product, since in the resultant fab-- ric the terry loops preferably completely hide the base knit portion of the fabric.

Figure 13 is an enlarged sectional view taken transversely through a portion of the fabric, showing somewhat the relation in which the fabric would appear in cross sec tion.

In the drawings, wherein for the purpose of illustration is shown only a preferred embodiment of this invention. the letter A may generally designate the improved knitting machine, which may be of various types suitable for knitting a fabric of the type herein described, but which includes novel operating mechanism as hereinafter described.

In the preferred construction the machine A preferably comprises a head ring or supporting frame 10, which rotatably supports therein the gear ring 11 centered on the portion 12 of the head ring or frame 10. The hollow cylinder 14 is rotatably supported in a suitable seat provided in the portion 12, and is of course concentric with the gear ring 11. Diametrically opposed supporting posts 15 and 16 are vertically carried by the gear ring 11, for rotation therewith, and a yoke 17 is carried at the top of these posts, in a detachable relation, as is usual. The bobbin supporting construction and guide for the threads or yarns is suitably supported above the yoke, in a. conventional relation, such as set forth in my copending application above referred to, and more specifically detailed in Patent 1,012,966 granted December 26, 1911, or in other approved manner, and includes a rotatable bobbin supporting piece 20, beneath which is a stationary ring 21, thru which centrally extends the stationary post 22, to which the dial 23 is keyed, as illustrated at 24 in Figure 2 of the drawings.

A dial cap 25 is rotatably supported upon the post 22, and is rotated with the gear ring 11 and with the posts 15 and 16, by means of an attaching bracket or arm 26 illustrated in Figure 1 of the drawings. It is of course understood that the dial cap 25 has attached thereto, preferably at 28, see Figure 2 of the drawings, a disc like cam 29, wherein a cam groove 30 is provided, which receives the butts 31 on the preferably spring beard type of dial needle 31, illustrated to best advantage in Figure 2 of the drawings, in order to project and retract the dial needles after the manner illustrated in Figures 4 and 5 of the drawings.

The dial 23 has a plurality of radially disposed grooves 33 therein, of any approved number, consistent with the size and character of the machine and fabric to be knitted, and these grooves 33 open at the periphery of the dial, and slidably receive therein individual reciprocating spring beard needles 31, as is well illustrated in various figures of the drawings.

A multiple section cam casing 35 may be bolted or otherwise keyed at 36 upon the gear ring 11, so as to surround the needle cylinder 14, and the same receives some of the cams thereon, to be subsequently described, for manipulating various needles of the two sets of cylinder needles to be subsequently described.

As is illustrated in Figure 1 of the drawings, means is provided to rotate the gear ring 11, including a driven shaft 38, having a gear 39 thereon which meshes with the downwardly facing gear teeth 40 on the lower surface of the ring gear 11, as is conventional, and it can readily be understood that upon rotation of the ring 11 the posts 15 and 16 will be rotated therewith, and thru the bracket arm 26 the dial cap 25 will be rotated, and likewise the connected cam 29, for causing reciprocation of the dial needles 33, which are located in individual grooves in the stationary dial 23.

The cylinder 14 includes a somewhat novel construction. It is of preferably hollow cylindrical formation, and as is best illustrated in Figure 6 of the drawings, and likewise illustrated to advantage in Figures 7 to 11 of the drawings, the said cylinder body is provided with external vertically disposed grooves 45 therealong, each of which reciprocably receive a spring beard needle 46 and a latch needle 47 The needles 46 form one series or set of spring beard needles adapted to control a terry yarn or thread in a cooperative relation with the latch needles 47 which form a second set or series of needles adapted to control knitting yarn and to knit the base fabric from which the terry loops project. The

needles

46 and 47 are operated upon by means of cams carried by the sections of the cam carrier 35 and by the upstanding annular flange 49 concentrically surrounding the cylinder 14. The set of

needles

46 and 47 are respectively provided with long and short inch, although this difference may vary, since it determines to-a considerable extent the length of the terry loops at one side of the fabric.

Referring now to the control of the knit and terry threads or yarns, and'the reception thereof in the fabric, the operation is more particularly designated in Figures 4 and 7 to 12 of the drawings, and the direction of rotation of the cams is as desi nated by the arrows adjacent the various figures of the drawings; it is of course understood that the cam cylinder and needle dial do not rotate, but that their respective needles reciprocate. The

needles

46 and 47 are of course disposed in alternating relation about the cylinder, and a single dial needle is provided for each pair of

needles

46 and 47; it being understood that the dial needles project in a reciprocating relation through the spaces between the pairs of needles'46 and 47, as is illustrated in Figure 5 of the drawings and elsewhere.

In the formation of the fabric, a typical series consists of a first terry thread or yarn 60; a first knit thread or yarn 61, a second terry thread or yarn 62; and a second knitting yarn or thread 63. It is of course under stood, and intended, that any number of such series may be provided on the machine A, and that the number of needles shown on said ma\ chine may be vastly increased, since the illustration of the invention requires, for clearness, that only the series illustrated need be shown, to designate the principle, and the arrangement illustrated may be multiplied any number of times desired, without departing from the spirit of the invention as claimed.

Referring now to operation of the needles of the cylinder and dial, by the respective ca ins thereof, for controlling the yarn threads above mentioned, it is to be noted from Figures 2 and 4 that the gear ring flange 49 has attached thereto

cams

66, 67, 68,- 69 and 7 O, in a circular relation; the cams being attached by means of set screws 71. as illustrated in Figure 2 of the drawings. The cams 72, 73, 74 and 75 are supported upon the cam casing 35, by means of detachable screws or elements 97,

' as is conventional.

As the gear ring 11' and the cam casing 35 rotate, all of the

cylinder needles

46 and 47 ride upon the inclined cam edge 76 of the cam 66; this cam 66 being sufficiently thick that the. edge 76 will engage both long and

short butts

50 and 51 as is well illustrated in Figure 4 of the drawings. The cam 66 on the inside face thereof s provided with a preferably horizontal short butt receiving groove 77, of a depth sufiicient to permit the short butts 51 of the knit thread receiving latch needles 47 to enter, whereas the elevation of the spring beard needles 46 is continned inasmuch as the longer butts 50 therereason for elevating the latch needles 47 on the cam 66, is in order to open the latches and permit the latches thereof to ride above portions of the terry yarn 62 and knit yarn 63 which have been previously received on said knitting needles 47, as will subsequently .ap-

pear, and by elevating the needles '47 on the cam 66 the latches thereof may be made to ride above the yarns held on the needles 47 at this location,in order to prepare for a cast off of said yarns at a subsequent knitting location. During the elevation of the needles 47 to the groove 77 of cam 66, the latches, of course, open due to the sliding of the yarns over the latches as the needles elevate, and the carrier 80 at the lower edge thereof acts as a cam to retain the latches of the needles 47 open until the first knitting yarn or thread 61 has been fed thereinto.

After the needles 46 havebecn elevated by the cam 66 to the desired extent, the first terry thread or yarn 60 is fed beneath the beards thereof, as illustrated in Figure 4, and immediately thereafter the long butts 50 of the needles 46 are pushed downwardly by coming into engagement therewith of the downwardly inclined cam edge 82 of the cam 72, as illustrated in Figure 4. Immediately prior to the lowering of the spring beard needles 46 to their lowest points on the cam 72, it is to be noted that the latch needles 47 are also lowered by the pushing downwardly of the short butts 51 thereof in a downwardly inclined cam groove 83, of cam 66, as is illustrated in dotted lines in Figure 4 of the drawings, and the purpose of lowering the latch needles at this location is in order to slip the

loops

86 and 87 of the second terry and knit yarns under the latches, and the butts 51 then ride along the horizonal groove 89, inthe cam 66, and the latch needles have then been lowered to a point on the cylinder approximately designated in Figures 4 and 7 of the drawings. In this location it is to he noted that under the latch of each of the latch needles 47 is engaged yarn looped

portions

86 and 87 of the terry and knit

threads

62 and 63 respectively, and the beard needles 46 are lowering with the first terry thread 60 under the beards thereof. The enlarged view Figure 7 is taken at the location where the cams 66 and 72'operate on the long and short butt needles 46 and 47 approximately at the designation B in Figure 4 of the drawings.

75 the latch needles 47 of the cylinder. Another I From the location B the cam 72 continues to lower the long butt spring beard needles 46 until the

butts

50 and 51 of the long and short butt needles 46 and 47 are on a horizontal line, and the butts thus ride along the lower cam edge 90 of the cam 72, and it is to be noted that the spring beard needles 46 at this location have drawn the terry yarn into the grooves 45 of the cylinder 14, with the intermediate portions of the terry yarn 60 between the grooves overhanging the top of the cylinder, as well illustrated in Figure 8 of the drawings, which designates in an enlarged fragmentary and somewhat diagrammatic manner the upper end relation of the

needles

46 and 47, at approximately the location C, designated in Figure 4 of the drawings. At this point it is to be noted that the spring beard needles 46 have drawn the thread 60 down beneath the hooks of the spring latch needles 47, although not below the latches of said latch needles 47', and at the location C the first knit thread 61 is fed through an opening 100 in the carrier 80 beneath the hooks of the elevated latch needles 47. Thus, at the location C it is to be noted that beneath the latch of each of the needles 47 the loops 86 and 87 above described are retained on the needles, and above the latches of each of the needles 47 and beneath the hooks of said needles the threads 60 and 61 are received, and the terry thread 60 is drawn downwardly into the groove 45 by the lowering of the spring beard needles 46, as is well illustrated in Figure 8 of the drawimmediately succeeding the location C, the cam 73 advances and the downwardly inclined cam edge 102 thereof rides against both the long and short butts 50 and 51 to project said needles 46 and 47 downwardly to a knitting point 103, and at which location the latch knitting needles 47 have been projected low enough to cast off the loop portions 86 and 87 previously beneath the latches thereof, and since the threads 60 and 61 are engaged beneath the hooks of the latch needles 47, the cast oif of the loop portions 86 and 87 receive the terry and knit threads 60 and 61 through the cast off loops, in order to thus form a wale of the loop 87 and the loop 86 follows around the wale and intermediate the wales provides terry loops 140, at the inside of the fabric; said loops 140 being formed as subsequently described, by the dial needles. At this knitting point 103, designated by letter D in Figure 4 of the drawings, and illustrated in enlarged relation in Figure 9 of the drawings, the latch needles 47 have been lowered suificiently to cause the knitting operation to take place, as can be readily understood, and well illustrated in the drawings, and it is to be noted to what extent the beard needles 46 have been lowered, to pull the first terry thread or yarn 60 downwardly into the grooves 45 of the cylinder 14, to provide relatively long terry loops 107 which will subse uentl form the loops at the opposite side of the fabric from the loops 140, say the outside of the fabric. The extent to which the beard needles 46 are retracted downwardly into the grooves 45 of the cylinder 14 determines the length of the loops 107, as is readily apparent from Figure 9 of the drawings.

Succeeding the knitting location 103 the cam 68 advances and the long and

short butts

50 and 51 both ride upwardly on the lower portion of the upwardly inclined edge 110 of the cam 68 in order to project both the beard and

knitting needles

46 and 47 upwardly. The beard needles 46 are elevated at the cam 68 in order that the terry loops 107 may be slipped from beneath the beards thereof in order to cast the same off during the next lowering of the needles 46; and the reason for elevating the latch needles 47 at the cam 68 is in order to open the latches thereof and receive beneath the hooks thereof the second terry yarn or thread 62, which is fed in cooperation on dial needles 31 and the cylinder latch needles 47'.

After the latch needles 47 have been elevated to open the latches thereof the butts 51 of the latch needles 47 ride along a horizontal cam groove portion 115 of the cam 68, but the long butts 50 of the needles 46 will continue to ride along the cam edge 110 to 1 the peak of the cam 68, due to the fact that at the groove 115 the cam 68 is not cut all the way through as is quite readily apparent, and will be understood by anyone skilled in this art. Thus, the beard needles 46 are elevated until the beards thereof are elevated above the top of the hooks of the latch needles 47,

which condition occurs at the peak of the cam 68. The extent to which the latch needles 47 are elevated by the cam 68 is limited, so that preferably the lower ends of the latches of said latch needles 47 here are received within the grooves 45, although the latches are held open by means of a guide rail 118, carried by the dial cap 25, and the latches of said latch needles 47 remain open for a considerable travel of the cam arrangement to a point which will be subsequently mentioned, and during their open position the needles 47 receive thereon the second terry yarn 62 and second knit yarn 63 as will be subsequently mentioned.

During the time that the

needles

46 and 47 have been projected upwardly by the riding of the cam 68 against the butts thereof, the dial needles 31 have been projected from their respective grooves in the dial 23, in an intermeshing relation through the spaces between each pair of

needles

46 and 47. The butts 31 of the needles 31 ride along the groove 30 of the dial, and are projected outwardly by riding along a portion 30 of the groove 30,

and the beards of the needles 31 are projected sufficiently beyond the circular line'of needles of the cylinder so that the second terry yarn or thread 62 may be fed from a thread carrier 119 over the needles 31 beneath the beards thereof, and immediately thereafter the needles 31 are retracted by the riding of the butts thereof along a groove portion 30". The needles 31', however, are not retracted until at a location where the same have received the second terry yarn 62 beneath the beards thereof and after the needles 47 have been fully elevated by the cam 68, so that upon retraction of the needles 31, the second terry yarn 62 will be looped beneath the hooks of and above the latches of the now open latch needles 47.

Upon continued rotation of the cam means, only the long butts 50 are caught on the downwardly inclined edge 120 of the cam 7 4, to project the spring beard needles 46 downwardly, to cast off the terry loops 107 previously received thereon, as at the position E designated in an enlarged relation in Figure 10, and during the riding of the long butts of the needles 46 along the cam edge 120, the beard presser 122 operates upon the beards of the now lowering beard needles 46, to close the beards thereof and enable the beards to slip past the terry thread or yarn 62, and the beards are held closed by the presser 122 for a sufiicient length of time that the lower ends of said beards will slip through the loops 107 of the first terry yarn 60, and at the location 125, at the lower end of the cam 74 the spring beard needles 46 have cast off theterry loops 107, as designated in somewhat diagrammatic relation in Figure 10 of the drawings, which shows an enlargement of a fragment of the cylinder and the needles operating in the grooves thereof, together with the dial needles in associated relation; this view being taken at approximately the location E designated in Figure 4 of the drawings. It is to be noted that at this location the second terry yarn 62 now lies upon the dial needles 31, beneath the beards thereof, and said yarn 62 is ready to be received in the hooks of the latch needles, which are open, upon lowering of said latch needles 47, and it is to be noted from Figure 10 that the open latches of the needles 47 have been elevated so that their lower ends are above the looped

portions

128 and 129 of the first terry thread 60 and first knit thread 61, and enables said looped

portions

128 and 129 to slip behind the latches to enable a cast off when the latch needles are next projected downwardly into the. cylinder as will besubsequently described.

Preferably just before the cam 75 operates upon the

needles

46 and 47, the second knitting thread 63 is fed through an opening 130 in a carrier 131, beneath the open hooks of the elevated latch needles 47, and since the beard needles 46 are retracted in the grooves of the cylinder 14 the thread 130 will not catch thereon. Immediately after the feeding of the second knitting thread 63, the downwardly inclined cam edge 135 of the cam 75 operates upon the short butts 51 of the needles 47, to lower the needles 47 in the grooves, andrelation in Figure 11 of the drawings; this being also designated in F igure 4 as location F, and the result of operation of the cam 75 on the

needles

46 and 47 is to permit the

loop portions

128 and 129 of the first terry and

first knit threads

60 and 61 to slip ofi of the latch needles, which in the meantime have caught the

yarns

62 and 63, and knitting is effected and the

loop portions

86 and 87 now on needles 47 are the same as above described at the start of the description of the op eration of the improved machine.

It is to be noted that the dial needles 31 after their retraction into the dial grooves succeeding the point E, pull the terry yarn 62 under the beards of said needles 31, into loops designated at 140 in Figure 11 of the drawings and likewise designated at 140 in Figure 7 of the drawings, the retraction of the needles 31 to provide these loops being of any degree desired, and these loops with respect to the latch needles 47 are illustrated in Figure 5. Immediately succeeding the location F, dial needles 31 are again projected outwardly by riding of the butts 31 in an inclined grooved portion 30; the beards of said needles being projected to a point outwardly beyond the circular line of

needles

46 and 47, and the beards are then operated upon by the beard presser 148, carried by the dial cap, to close said beards of the dial needles 31, and immediately thereafter the butts 31 of the dial needles 31 are operated upon by a cam groove portion 30 and the dial needles retracted to cause the beards to cast off the second terry thread loops 140. The loops 107 at about the location F are shown disappearing into the cylinder, in Figure 11 of the drawings.

The knitted fabric of course passes downwardly through the passageway 150 in the cylinder 14, from the top edge of the cylinder thru the space 151 between the dial 23 and the top of the cylinder 14, and as illustrated in Figure 11 the loops 107 are shown just disappearing into the cylinder, and the terry loops 107 will be at the outside of the fabric, whereas the terry loops 140 when cast off will be at the inside of the fabric, in approximately the relation illustrated in Figure 13, although this view is also partly diagrammatic, since due to the method and the disposed relation of the terry loops, to hide the base fabric, the real nature of the fabric is practically incapable of fair illustration.

The relation of the wales and terry loops is illustrated to advantage in Figure 12 of the drawings, which only gives a representation of the relative location of the terry loops with respect to the base knitted fabric, and therein it is shown that the terry yarns follow about the wales of the knit yarns with which they are associated in the knitting operation, and intermediate the wales, the terry yarns provide the loops which produce the matted terry looped appearance on towelling, in simulation of the slack terry loop arrangement of conventional woven towelling.

Any multiple of the series of cams in the relation above described may be provided upon the machines, to produce a large tubular knitted fabric, and it is to be understood that the invention as illustrated applies merely to the principle and the mechanism employed to carry out that principle.

Various changes in the shape, size, and arrangement of parts of the improved knitting machine herein shown and described, as well as alteration in the steps of carrying out the method of knitting may be made to the form of invention herein shown and de scribed, without departing from the spirit of the invention or the scope of the claims.
