JOSEEH B. MAGNAMEE, OF LLANERCH, PENNSYLVANIA, ASSIGNOR TO B. BRINTON COMPANY, 02 FRANKFORIO, EHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

Application filed. October 21, 1925.

To all whom it may concern:

Be it known that I, Josnrrr B. MAONAMEE, a citizen of the United States, residing at Llanerch, in the county of Delaware and State of Pennsylvania, have invented certain new anduseful Improvements in Dial- Aligning Devices, of which the following is a specificationf v My said invention consists infa dial aligning device for rib knitting machines. As is well understood bythose skilled in the art circular rib knitting machines having revolving needlecams are commonly provided with means known as dogs for holding the dial in correct angular position relatively to the needle cylinder so as to insure correct positioning of the dial needles relatively to the cylinder needles,,each dial needle being mid way between two cylinder needles and vice versa. Such devices are commonly objectionable to a certain extent, especially when used with delicate fabrics, by reason of the fact that the fabric must be pulled down between two contacting devices or dogs which make dog marks in the fabric such marks varying from a very faint streak to a distinct depression or even a torn place in the fabric. These dog marks are of course more or less objectionable according to the extent of the injury to the fabric. 1 have found that by the use of rollers which extend over a considerable number of wales and which are mounted so as to be capable of rocking transversely of the wales, or transversely of the direction of movement of the fabric, the objectionable features of dial and cylinder machines using dogs are largely eliminated.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure l is an elevation of a dial and cylinder knitting machine of the type known as a body machine, viewed'from the left in Fig. 3, parts being broken away for clearer I showing,

Serial No. 63,841.

indicates a part of the stationary frame of the machine provided at its upper end with a ring 11 on which are supported a plurality of brackets 12 held in place by set-screws l3 bearing against the under side of the. ring and set-screws 1 1 bearing against the said under side and aninclined face 15 on the ring for drawing the brackets securely down to place the set-screws 14- serving to position the brackets by swinging them radially and also to fix them against inward swinging movement. held in looking position by means of locknuts 16. A cam ring 17 is mounted for rotation on the ring 11 and a needle cylinder 18 is fixed in relation to the frame inside the cam ring. A dial'19 is supported at the upper verge of the needle cylinder in any conventional or desirable manner and said dial has depending therefrom a bracket 20 with an oil cup 21 serving to keep the oil from the driving shaft of the dial cam cap (not shown) off the fabricas it moves downward through the cylinder. The bracket 20 is connected by a link 22 to a part 23 having at its ends abutments 24 and 25 provided with inclined faces positioned in a manner to be opposed to the direction of rotation of the cam ring and the dial cam cap.

The tubular fabric passes at oposite sides of the tube between the faces of abutments 24 and 25 and the adjacent faces of a pair of cylindrical rollers 26 journaled in yokes 27 which are pivotally mounted at 28. in a manner to permit them to oscillate about vertical axes while holding the axes of the rollers substantially in alignment with the planes of the faces on abutments 2e and 25. The oscillation permitted by the pivotal mounting ofQthe yokes enables slight inequalities in the cloth to pass between the rollers and the inclined faces without damage to the cloth and the width of the fabric in contact with said faces and with the rollers is such as prabtically to eliminate any possibility of dog marks" in the completed fabric. The means for carrying the yoke comprises a forked support 29 with either one fork or a pair of forks perforated to receive the bolt 28 and another fork with a threaded aperture for a set-screw 30 held in plac by a lock-nut 31. The support is pivoted at 32 so that adjustment of the setscrew brings the roller 26 closer to or further The set-screws are shown a support from the almtment on the tace 24: and thus determines the pressure of the roller on the cloth.

At the opposite side of the machine is 33 ot somewhat dilierent term, this support being in the form of a bent lever having a bracket 27 mounted at the angle between the two principal arms and having a set-screw 3-1: in a threaded aperture at the outer end, the lever being pivoted at 15 on a bracket at slightly di'l ierent in term 'trom the bracket 37 on which the support is pivoted. Either t'orm oi lever and either term of bracket may be used as desired. The two brackets are connectel by a rod 238 to which the braelnits are clamped by set screws 39, the rod 38 serving to hold the brackets against rotation whereby the adjustment of the rollers would be lost.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit at the invention and thereitore I do not limit: mvsel't to what is shown in the drawings and described in the specification but only as indicated in the appendai claims.

Having thus fully described my said invention, what I claim new and desire to secure by Letters Patent, is:

1. In a knitting machine, a needle cylinder, a dial, and connections between them including a cylindrical roller engaging one face of the fabric transversely of the wales, means in contact with the opposite face of the fabric for holding the fabric in engagement with said roller tl'iroughont the length oi the roller, and supporting means For the opposed fabric-engaging devices permitting a relative rocking movei'nent thereot in a direction transverse to the wales of the fabric, substantially as set torth.

#3. in a knitting machine. a needle cylinder, a dial, and connections between them comprising a llat-taecd element engaging one taco ot the knitted tabric, a roller opposite the tint three of said element, and supporting means for the flat-faced element and the roller permitting relative rocking movement thereoi in a direction crosswise oi the wales ol' the Fabric, substantially as set? i'orth.

ii, in a knitting machine, a needle c vlindeiu a dial. and connections between them comprising an element having an elongated thee in position for engagement with the knitted fabric, a roller engaging the fabric opposite said lace, and means supporting the roller for movement about an axis perpendicular to its axis o't rotation, substantially as set forth.

t. In a knitting machine, a needle cylinder, a dial, and connections between them comprising an element having an elongated face in position for engagen'ient with the knitted fabric, a roller engaging the fabric opposite said iace, means supporting the roller for movement about an axis perpendicular to its axisof rotation, and means for adjusting the roller toward and from said. "face, substantially as set forth.

In a knitting machine, a needle cylinder, a dial, and coin'iections between them comprising an element having an elongated face in position for engagement with the knitted fabric, a roller engaging the fabric opposite said face, a support pivotally mounted on the upright frame of the ma chine, a pair of arms on said support, a yoke on one of said arms, a roller on said )(Oh't? engaging said elongated face, and a screw on the other arm extending outward into engagement with alixed abutment on the machine, snbstantiall as set forth.

(3. In a knitting machine, a needle cylinder, a dial, and connections between them comprising an element depending from the dial said element having l'lat faces positioned to engage the tubular knitted fabric at opposite sides of the tube, yokes pivotally sn 'iported outside the tube, and cylindrical rollers on said yokes engaging the Fabric opposite said faces, substantially as set forth.

7. In a knitting machine, a needle cylinder, a dial, and connections between them comprising an element depending from the dial said element having flat faces positioned to engage the tubular knitted fabric at opposite sides of the tube, yokes pivotally supported outside the tube, rollers on said yokes engaging the fabric opposite said faces, and means including a support for each of said vokes pivoted on the machine trame whereby the rollers may be adjusted toward and tron] said :laces, substantially as set forth.

In witness whereof, have hereunto set my hand and seal at .lhiladclphia, Pennsylvania this th day of September, A. D. nineteen hundred and twenty-five,
